摘要： 777,090. Copy-milling. ONSRUD MACHINE WORKS, Inc. May 19, 1955 [June 8, 1954], No. 14459/55. Class 83 (3). A contour-milling machine comprises a cutter-carrier 18 swingable on a carriage 12 about an axis 19 at rightangles to the relative path of travel of the carriage and a work-table 10, a rotary-cutter 14 on a parallel axis, a second carrier 25 which may carry a roller 26 and is interposed between the carrier 18 and a track 27 on which the carrier 25 bears, and jack-means 34 for moving the carriers to- and-from each other. The track 27 is adjusted to be truly horizontal by screws 30, 31. As the carriage 12 is traversed by rack-means to cut a wing spar, the jack is adjusted to vary the position of the cutter by a motor 37 which, through bevel gears, rotates a nut 35. The motor is controlled by a template 50 having one edge 53 contoured and the other formed with a driving rack engaged by a worm 55 driven by the mechanism traversing the carriage 12 or by a rack on the table 10. The template is engaged by a reciprocating tracer 58 which controls the position of the tool and a double-armed tilting-tracer which decreases or increases the speed of the head 12 according to the slope of the template. The carriers 18, 25 are moved to an inoperative position by a fluid-pressure device 21 which, in operation, also assists in relieving the pressure of the roller 26 on the track 27.

摘要： 275,572. Onsrud Machine Works, Inc., (Assignees of Onsrud, R. F.). Aug. 4, 1926, [Convention date]. Regulating.-In a turbine provided with a nozzle 10 for starting and ior idle running, the additional nozzles 11 for full-load running are supplied by a passage 23 and a valve 16 actuated by a governing device 30 which is operated by the working-fluid discharged from the rotor vanes 12. The device 30 comprises a lever pivotally mounted on the casing by a pin 38 and bent at its outer end so that this part 35, which carries, angular vanes 36, lies between the first and second wheels 5, 6. A spring 32, the tension of which is adjustable, holds the lever so as to close a relief portion 26 by means of a ball valve 27. The valve 16 has a passage 28 admitting the fluid to its interior and is held closed by a spring 25. The operation of the device 30 is as follows. At low speeds the fluid from the starting nozzle 10 is deflected from the vanes 12 backward into the vanes 36, thereby moving the lever 30 to open the relief port 26. The valve 16 is thereupon opened by the fluid pressure, and the fluid from the chest 14 is admitted to the nozzles 11. At higher speeds the deflection off the fluid is decreased, and the lever 30 tends to return to normal position to close the valve 16 and decrease the speed.

摘要： 1,075,248. Copy-milling. ONSRUD MACHINE WORKS Inc. Aug. 14, 1964 [Nov. 15, 1963], No. 33341/64. Heading B3K. A router comprises a workpiece and patternholding fixture and a programme mechanism for moving a workpiece 49 along a path prescribed by the pattern 46 by energizing first and second reversible power units 31 (32), 37 (38), alternately, the power units being positioned to move the table in linear directions at rightangles to each other. A bed plate 21 can be adjusted vertically by a hand wheel 22 and carries brackets 24 supporting rods 26 on which slide blocks 27 attached to a plate 28. The plate carries a bracket 35, attached to the rods of hydraulic and pneumatic cylinders 31, 32, and a rail 30 on which slides a block 36. The block 36 carries an angle bar 42 to which is bolted the pattern block 46 having a guide groove 48, Fig. 2, on its under-surface. The block carries pneumatic clamps 50 to secure the workpiece 49. The guide-groove is engaged by a roller 53 1 , Fig. 9, which may be retracted by a lever operated by an hydraulic device 54. In the groove are mounted a number of dogs 59 which may engage the end of a plunger 57 to actuate an hydraulic valve 56, which, by way of a speed control valve 105 1 , advances a ratchet wheel 65 attached to a cam drum 60. The drum has a series of grooves in which dogs are positioned to actuate pneumatic valves 81-84 and hydraulic valves 85-88 in a given sequence. In operation, the hydraulic and pneumatic means are used to hold the follower 53 1 against one side of the guide groove. Thus, an hydraulic ram is used to move the pattern in one direction while the pattern is urged in a direction at right-angles thereto by a pneumatic ram. Meanwhile, the other two rams are allowed to move freely. The speed of movement is controlled by a valve 99.

摘要： 1,011,519. Woodworking. ONSRUD MACHINE WORKS Inc. Oct. 28, 1964 [Nov. 15, 1963], No. 43987/64. Heading B5L. A profiling machine comprises a work-table 14 mounted for horizontal reciprocation past a stationary cutter unit 12 and adapted to carry a profile pattern 84 and a workpiece 80, first and second cutter carriages 27, 29 in the cutter unit each mounted for horizontal reciprocation towards and away from the work-table, reversible means for each carriage operable to urge the carriages resiliently toward the worktable, a vertical axis motor driven spindle on each carriage and a cutter 44, 77 on each spindle, a pattern follower 43, 78 on each carriage coaxial with the respective spindle, means 21 for driving the table through a forward stroke past the cutter unit and automatically returning the table to its starting position, and a pattern 84 on the worktable engageable endwise by the followers for positioning the cutters individually relative to the profile of the pattern when the carriages are urged towards the work-table by the reversing means. The work-table 14 is slidable longitudinally on a frame 10 supported on pedestals 11, 12, 13 and has a flat portion 15 on which are a plurality of clamps 16 for securing the pattern 84. A bridge 17 is supported by uprights 18, 19 mounted on the table and has a plurality of vertically adjustable clamps 20 for the workpiece 80. The table 14 is movable past the cutter unit 12 and back to its initial position by a hydraulic piston-and-cylinder device under the control of a valve 22 which is automatically operated to effect the forward and return stroke of the table by a pneumatically operated cylinder 23 in an electrically controlled pneumatic circuit. The valve is also actuated by a lever 25 having a follower engaging a cam 24 on the work-table to control the speed of the table. The cutter unit is mounted on the pedestal 12 and has a pair of horizontal rods 31 for slidably supporting the carriage 30 of the cutter device 27 which has a vertically disposed motor 34 mounted on a slide 35 which, in turn, is adjustable along vertical guideways in the carriage 30 by a screw 38. The motor is coupled to a spindle 40 which has its upper end supported by an arbor 41 and carries a cutter 44 and a freelyrotatable follower 43. The carriage 30 is movable towards and away from the work-table 14 by a pneumatic motor 50 having a rod 51 formed with a head 53 abutting a spring which urges a bracket 52 secured to the carriage against a collar 55 secured to the rod. The cutting device 29 is also mounted on the pedestal 12 and has a carriage 30 1 movable towards and away from the work-table in a similar manner to the carriage 30 by the rod 51 1 of a second pneumatic motor. A base member 60 is vertically adjustable by means of a screw 62 in guideways 61 on the carriage 30 1 and supports a column 69 carrying a housing 68 which has a pair of vertical guide rods 66 for slidably supporting a motor 64 having a spindle on which is a cutter 77. The weight of the motor 64 is counterbalanced by a pneumatic cylinder in the housing 68, and a second pneumatic cylinder is provided for raising and lowering the motor and is controlled by a valve 81 actuated by a button 82 which co-operates with a cam or rail 83 projecting below the pattern 84. A shoe 76 is vertically adjustable on the motor 64, the cutter extending below the shoe, and a follower roller 78 coaxial with the cutter 77 is mounted on the base 60. In Fig. 7 (not shown), both cutters may rotate in the same direction, the first cutter effecting a rough shaping of the workpiece under the control of the pattern 91, and the second cutter effecting a final shaping, or alternatively, the cutters may rotate in opposite directions, the motor 64 being reversible. The pattern may be formed with two levels 84, 84 1 and each follower engages a respective level to control its associated cutter. The first cutter may thus be a face contour cutter and the second a grooving cutter, the level of the pattern controlling the second cutter being masked at various parts so that only predetermined parts of the workpiece are grooved. In Fig. 10 (not shown) the first cutter may be used to shape the edge of the workpiece under the control of the level 84 1 of the pattern which is engaged by the follower 44, the second cutter 77 is controlled horizontally by the follower 28 engaging the lower level 84 of the pattern, and the raising and lowering of the second cutter is controlled by the cam rail 83 engaging the button 82 of the valve 81 controlling the motor for raising and lowering the motor 64. The followers 43 and 78 are resiliently urged against the pattern by the springs on the rods 51, 511 of the pneumatic motors 50 during the forward feed of the table which is automatically reversed at the end of its stroke to return the machined workpiece to its initial loading and unloading position, the motor 64 being raised and the motors 50 operated at the end of the forward stroke to retract the cutters and followers from the workpiece and pattern. Blocks 96, Fig. 1, may be mounted at each end of the workpiece and pattern to assist the smooth engagement of the cutters and followers with the workpiece and pattern.

摘要： 708,411. Copy-milling. ONSRUD MACHINE WORKS, Inc. July 10, 1952 [Jan. 31, 1952], No. 17408/52. Class 83 (3). [Also in Group XXIII] A pattern-controlled routing machine comprises a carriage 8 straddling a work-bed 28 and movable along it by a motor 10 driving a rack and pinion 11, 12 through a belt or chain and a worm drive, an annular support 1 traversable across the carriage 8 by a motor 14 and lead screw 13 and rotatable on its axis by a motor 4 and gearing 5, 6, and a routing head 2 carried within the annular support on an arm 18 pivoted on a bracket 19. The pattern follower comprises a collar 27 surrounding the cutter spindle 16 and engaging the pattern 31 mounted above the work 3. The motors 4, 10, 14, are variablespeed, direct-current amplidyne-controlled units and are controlled to cause the routing head to move round the pattern and work by, in the case of the longitudinal and traverse motors 10, 14 a joy-stick 129 on a controller 128, and in the case of the annular support motor 4, by a selsyn transmitter 55 having a handle 57 which, when rotated, controls the motor 4 through a selsyn receiver 58 to give the same angular movement to the annular support. During the copying movement a fluid-pressure cylinder 62, sliding on a piston rod 60 fitted across a chord of the annular support and having a pair of flanges 66 engaging a tooth 67 on the routing head, pivots the arm 18 and presses the follower laterally into engagement with the pattern with a yielding force substantially normal to the line of the pattern. The routing head 2 and the follower bracket 24 are independently movable up and down by, respectively, a pair of yoked fluid-pressure cylinders 20 and a cylinder 26. The annular support 1 is mounted in a frame 34 by an oil-bathed bearing 43 on the gear ring 6 and a pair of uprights 47 support a bridge member 48 carrying a distributor 49 having a rotary shaft 68 with collector rings 74 and brushes 75 for supplying current to the motor 4, and a conical valve-type distributor 78 for supplying compressed air to the cylinders 20, 26, and for supplying lubricant and compressed air to the follower bracket 24 for lubricating the cutter and blowing away chips. Adjustable stops are provided for limiting the movements of the follower, routing head, lateral-motion cylinder 62 and the motors 10, 14. Compressed air from a supply 97 is connected to a master valve 99, which is of the reciprocable piston type and is controlled by an operating valve 109, the latter preferably being footoperated. From the master valve, lines 100, 101, are connected to the ends of the follower cylinder 26, and from the line 100, a line 102 leads to a master valve 103 controlled by an operating valve 110 and thence to the routing head cylinders 20, and a further line 106 leads through a reducing valve 107 and blow-off valve 108 to one end of the lateral-motion cylinder 62. Flow control valves 117, 118, cushion the downward movements of the pistons 20, 26. The valve 109 is operated first so that the follower is lowered to the pattern level and reduced pressure is supplied to the cylinder 62 to move the follower laterally at a slower rate to engage the pattern. The valve 110 can then be operated to lower or raise the cutter independently of the follower but, to prevent the follower being raised without also raising the cutter, an interconnecting line 119 having a non-return valve 120 is provided.

摘要： 692,527. Centrifugal governors; elastic-fluid turbines. ONSRUD MACHINE WORKS, Inc. May 28, 1951 [Feb, 21, 1951], No. 12446/51. Classes 57 and 110(iii) [Also in Group XXIX] A centrifugal governor, particularly for controlling the flow of pressure fluid to a high speed turbine rotor 10 driving a rotary tool, comprises a centrifugally expansible elastic body 33 carried by a member 9 secured to a driving shaft 3 and an axially movable sleeve 25 radially confining the elastic body and abutting one end thereof, whereby the body is caused to expand axially under centrifugal force and move the sleeve which causes the speed to be controlled. The latter is keyed to the elastic body at 34 to ensure its return movement. The flow of pressure fluid from an inlet 14 through passages 15, 19 leading to a turbine nozzle 11 is controlled by a valve 16 which is loaded by a spring 21 and is subjected to fluid pressure on its front surface through the passage 15 and on its rear surface through passages 22, 22.1 in which an adjustable throttle 23 may be provided. A bleed passage 24. controlled by a shoulder 27 on the governor sleeve 25, is normally open to atmosphere so that the pressure on the rear of the valve 16 is reduced and the latter remains open. When the speed increases beyond a predetermined value the bleed passage 24 closes and full inlet pressure acts on the rear of the valve 16 and closes it. The bleed passage 24 is formed in a plug member 35 and the inner end of the passage is eccentric with the axis of the plug' member. Rotation of the latter adjusts the axial position of the inner end of the passage with respect to the shoulder 27 and thus the speed at which the bleed passage is closed. A second nozzle 11.1 uncontrolled by the governor is provided. In another embodiment the governor sleeve 25 is loaded axially by a spring washer. Instead of the second nozzle the valve 16 is provided with a restricted bore which is always open to the nozzle.
