摘要： 652,547. Turning. WARD & CO., Ltd., H. W., and HOOSON, G. C. Aug. 25, 1948, No. 22423. [Class 83 (iii)] In a lathe, particularly a capstan lathe, in which a slide such as a capstan slide is manually movable through rack- and-pinion gearing the latter is combined with a locking device in the form of a unidirectional clutch adapted to prevent undesired return movement of the slide. A capstan slide carries a rack c, Fig. 1, with which meshes a pinion b carried at the end of a shaft a journalled in the machine bed. A hand-operated member e is keyed to a sleeve g which is freely rotatable on the other end of shaft a. The sleeve is provided with projections h which engage in recesses j in a member i keyed to the shaft a. Rollers n, Fig. 2, are spring-pressed into wedging relation between the member i and a surrounding stationary ring o and these prevent a force on the slide from moving it in reverse direction after adjustment. Rotation of the hand-member e through the projections h, pushes the rollers out of wedgeengagement and enables the slide to be operated reversely by the hand levers f. On forward adjustment of the slide by the hand levers the projections h engage the free ends of the recesses j and the wedge-pieces are inoperative in this direction. The sleeve g and complementary clutch-member i may be locked together by a bolt p.

摘要： 630,833. Lathe details. WARD & CO., Ltd., H. W., and HOOSON, G. C. Dec. 11, 1947, No. 32667. [Class 83 (iii)] Bar-feed mechanism for a lathe comprises a reciprocable holder a actuated by spring means i in the forward direction, a catch m for retaining the holder against the action of the spring i, and reciprocable means q, which is operable in one direction to retract the holder against the spring until retained by the catch and operable in the other direction to release the catch and allow the spring to advance the holder. As applied to a hollow-spindle lathe, the tubular holder a, Fig. 3, has a split collet a 1 for frictionally gripping the stock and is rotatablymounted in a bearing located in an arm c secured to a movable feed-rod d. A bridgemember g, which is attached by the spring i to a casing e, is secured to the rod d and is slidable on a stationary guide-rod f ; a projection k on the member g co-operates with the catch m which is controlled by a spring n. The rod d has slidably mounted thereon a rack-sleeve p co-operating with a pinion s, and a second pinion r, interconnected and coaxial with the pinion s, co-operates with the reciprocating bar-rack q which is actuated by a hand lever associated with the operating mechanism of the lathe chuck. When the hand lever is actuated to close the chuck on the bar, the rack q rotates the pinions r, s, to displace the rod d until it is retained by the catch m, the collet a 1 being drawn along the stock. The bar q, when moved in the opposite direction to open the chuck, releases the catch m and allows the holder a to feed the stock under the influence of the spring i. In the modification shown in Fig. 4, the racks and pinions are replaced by drums r, s and tapes u, x. The Provisional Specification describes also the bar q as being attached to the hand lever which has free movement in addition to that required for operating the chuck.

摘要： 629,199. Controlling change-speed gearing. WARD & CO., Ltd., H. W., and HOOSON, G. C. Sept. 15, 1947, No. 25171. [Class 80 (ii)] A lathe headstock or like change-speed gear has slidable gear elements each actuated by an individual hydraulic unit controlled by its own manually-operated preselection valve, separate manual means being provided which both operates a single main executive valve and releases a main clutch having a driven shaft brake. A centrifugally-operated valve may prevent forward-reverse executive action above a predetermined speed of the corresponding gear elements. Power inching during gear changing may be effected hydraulically or mechanically. As shown applied to a lathe or other machine tool headstock in which slidable pinion groups a, b, c combine to give twelve speeds and a further forward-neutral-reverse group d conveys the resultant drive to the chuck or work spindle, sliding of the groups is effected by hydraulic pistons f, m, p, i operated by pressure fluid supplied by pumps P1 ... P5 and controlled by preselective plunger valves f1, m1 p1, i1 and an executive plunger valve 8. The valves f1, m1, p1, i1 are operated, preferably against springs (not shown) through rotary cams 10 ... 12 and 15 by control knobs 14, 18 respectively, and may be pre-set whilst the machine is running, the speed selected being rendered effective only when the change-speed mechanism has been disconnected from the power source and brought to rest as follows. Whilst the machine is running, the valve 8 connects the pumps P1 ... P5 through its hollow interior to exhaust as shown, and prevents operative pressure building up in the control system. The valve 8 has a lost-motion connection to an extension 6 on a cam 2 rotated by a hand lever 3 having a transverse pivotal connection 4 to the cam shaft and moving in a slotted gate 5. Initial movement of the lever 3 to the right acts through a cam follower z and a rod x to disengage the main pulley-driven clutch s, t. Continued movement to the right, allowed by transverse movement of the lever into a second slot, brings the driven clutch member first into connection with a brake. member w and then into a central neutral position. The lost-motion in the connection 6, 8 has now been taken up, and a final movement of the lever 3 closes the valve 8 to render the pressure fluid effective on the control system according to the setting of the valves f1, m1, p1, i1 as follows. Pumps P1, P2 constantly supply pressure fluid directly to both sides of the piston f, which has a gearing operative position at the middle, as well as at either end, of its stroke. Preselective movement of the valve f1 to the position shown connects ports 20, 21 to exhaust ports E1, E2 and, when the valve 8 is closed, centralizes the piston f to bring in the corresponding speed. Subsequent preselective movement of the valve f1 in either direction connects one or other of the pumps P1, P2 to an exhaust port E3 and prevents the pressure fluid from that pump becoming operative when the .valve 8 is closed, so that the piston f moves correspondingly to one or other end position. Operation of the piston i is effected similarly in conjunction with the pumps P4, P5 and the valve i1. Each piston m, p has only two gearing operative positions, one at either end of its stroke, opposite sides of each piston being connected alternately to the pump P3 and to an exhaust port E4 respectively by movement of the corresponding valves m1, p1. To prevent inadvertent actuation of the valves f1, m1, p1, i1 when the valve 8 is closed an interlock (not shown) may be provided between the lever 3 and the spindles 13, 16 of the knobs 14, 18. The gate 5 may co-act with the extension 6 in which case the extension may be formed in one with the lever 3. To prevent operation of the piston i when the pinion group d is rotating too rapidly, centrifugal weights 25 thereon act on a valve 27 to connect the pumps P4, P5 to exhaust above a pre-determined speed of the group. Power inching of a pinion group, as the group a, during gear changing, may be effected by tight engagement of the main clutch, or by rotating the gears through turbine means associated therewith, as from a pump P6. According to the Provisional Specification, such inching may be effected by a light spring pad disposed in the main clutch, by jets of oil impinging at high pressure on one or more gears in the train, or by the employment of fluid flywheel or like devices.

摘要： 664,759. Interconnected valves. WARD & CO., Ltd., H. W., and HOOSON, G. C. Feb. 10, 1950 [Feb. 14, 1949], No. 3950/49. Class 135. A manually-operable valve for controlling the actuating mechanism of a chuck and the work-feeding mechanism comprises a body part a having passages b, c leading respectively from and to a fluid-supply pump, and passages d, e leading to the chuck-actuating and work-feeding mechanisms respectively, the valve also comprising a rotary cylindrical control member g having an axial bore h communicating with the passages b, c, and radial passages i and peripheral grooves j which can be moved into and out of communication with the various passages in the bodypart. A hand lever k is pivoted to the outer end of the member g, and in the bore h is a slidable cylindrical plug m controlling an adjacent radial outer passage leading to the passage c. The chuck is actuated to grip the work when the member g is in one of its limiting positions, determined by the engagement of a stop peg n with a segmental peripheral groove therein, and the passage c is closed by the plug m. To release the chuck, the hand lever is first moved about its pivot to cause the plug to open the passage c, and then the member g is turned to its other limiting position, whereupon the hand lever is moved about its pivot to cause the plug to re-close the passage c. Pressure fluid can now pass to the chuck-actuating mechanism for releasing the chuck, and also to the work-feeding mechanism for advancing the work through the chuck. On returning the hand lever to its initial position, the chuck is caused to regrip the work and the work-feeding mechanism is put out of action.

摘要： 597,454. Cam actuation of switches. MACHINERY (BIRMINGHAM), Ltd., and HOOSON, G. C. Aug. 20, 1945, No. 21223. [Class 38(v)] [Also in Group XXIX] A master control device for preventing the starting of any but a selected one of a number of machines e.g. riveting presses, each having its own controlling means comprises a manually operable selector lever, agate for determining the positions to which the lever can be moved and means operable by the selector lever for over-riding the controlling means associated with the individual machines. The selector lever m moves in a gate n having a longitudinal slot o and three branch slots p and is mounted on an angulary and axially movable shaft j carrying three cams k which in the selective positions of the lever are located opposite bell crank levers f pivotally mounted on a shaft g. The levers f are loaded by springs i and act either directly or through adjustable abutments h to hold plunger valve e closed against the fluid pressure in a common supply pipe b. Individual valves are permitted to open when a cam k depresses the respective lever f on raising the lever m in the corresponding slot p. Pressure fluid may then pass through an outlet d to the controlling means of the selected machine. Meanwhile the fluid pressure is cut off from the controlling means of the other machines by the remaining valves e. Each lever f may open a spring-loaded electric switch w when in its valve closing position. Where the individual machine controlling means comprise electromagnetically-operated valves, the switches controlling these valves may be in circuit with the switches w which therefore provide an additional safeguard against undesired starting. Each valveoutlet passage c has an adjustable spring- loaded relief valve q. In the case of electrically-operated machines the levers are adapted to actuate switches instead of valves.

摘要： A precision positioning mount for UV-cured adhesives that provides adhesive junctions between modular assembly mounts and structural elements. Contact edges are placed on a first fixating area of an adhesive junction. The contact edges are pronounced edges of faces that slide along a second fixating area during the adjustment process. Thus, the assembly modules and structural elements are precisely referenced before, during and after their positioning and orientating. First and second fixating areas form a cavity that provides a volume for the adhesive. The mounts and structural elements are preferably made of sapphire for increased thermal conductivity. The elements of the assembly mounts are modular and interchangeable and provide various positioning modes.
