摘要： 382,608. Feeding webs. SMITH, E. J., 18, Whitefriars Street, London. Sept. 21, 1931, No. 24963/32. Divided on 382,383. [Class 100 (i).] A web-tensioning mechanism for use with printing or other machines having a number of web rolls mounted for use in turn as the active roll comprises brakes upon the spindles of the rolls selectively controlled by a pilot roller engaging the web, and straps or other friction members engaging the surface of the active roll, the normal running tension being wholly or in part created by the straps &c. and an additional braking force being applied to the roll spindles when the web breaks or the machine is stopped. Three rolls 10 are mounted on spindles 16 carried by frames 12 rotatably mounted by means of a shaft 15 to bring the rolls in succession to the feeding position in which the roll engages straps 17 tensioned by weights 20. Each spindle 16 is provided with a brake drum 26 engaged by brake shoes 24 carrying armatures 27 of an electromagnet 28. Commutator rings divided into three segments 30 are mounted on one of the frames 12 and the segments are connected to the corresponding solenoids, the segments relating to the active roll also being connected by brushes 32 to a source of current supply. A pilot roller 36 engaging the web 11 is carried by an arm 37 fixed to a rock-shaft 38 which also carries the arm 43 of a rheostat 44 arranged in one of the leads to the brushes 32, so that changes in the position of the roller 36 cause a corresponding change in the current supply to the solenoid 28. The roller is held against the web by a torsion spring on the shaft 38 one end of the spring being fixed to the arm 37 and the other end to a stationary sleeve adjustable by a worm 41 and quadrant 42. Specification 382,383 is referred to.

摘要： 341,947. Electric clocks. SMITH, S. J., GRIMBLEY, J. F., and TELEPHONE MANUFACTURING CO. (1929), Ltd., Hollingsworth Works, Martell Road, West Dulwich, London. Oct. 23, 1929, Nos. 32157/29 and 25075/30. [Class 139.] Ratchet gearing.-Dial mechanism for an electric secondary clock consists of a ratchet drive for the hands which is operated by an electromagnet with an oscillating armature, there being an inertia device which (for silence) retards the return of the armature under spring pressure. This inertia device is a flywheel driven in one direction by a pawl formed of bristles or hairs. The armature 19 of magnet 30, 31 (21, 22 being the pole faces) has pivoted in it a wire pawl 24 which, when the magnet is energized from the master clock once every half minute, drives the ratchet 18 one tooth, this rotating the clock hands one step through a worm gear. The armature spindle 20 carries a cup 35 having a saw cut which holds one end of a return spring 3 (for the armature), the other end of which is anchored at 38 by an adjustable milled disc. Spindle 20 also carries a member 48 holding bristles 39 which coact with the velvet (or chamois leather) face of a flywheel 40 pivoted at 42. When the armature is attracted to drive the ratchet 18 the bristles 39 move to the right in Fig. 2, idly over the surface 43 but on the return movement the bristles engage the velvet and rotate the flywheel. The pawl 24 has a tail piece which is magnetic and coacts with a pole face, when the magnet in energized, to draw the pawl firmly into engagement with the ratchet. A pad 44 of felt deadens the sound of the pawl tail as it descends, On retraction of pawl 24 an inclined stop 45. covered with felt or chamois leather, holds the pawl in engagement with the ratchet. The backstop pawl 25 is pivoted in the frame and after passing over a pole face is bent upwardly to provide a tail for releasing it from the ratchet. The part of pawl 25 overlying the pole face is rubber-covered for silence. The worm gearing, &c. for the clock hands, the ratchet drive (including armature), and the magnet coils are attached as three separate units to the back of the clock face. Specification 297,891 is referred to in the first Provisional Specification. Mechanism such as that described may be used in a barograph.

摘要： 341,261. Feeding webs. SMITH, E. J., 18, Whitefriars Street, Fleet Street, London. Jan. 10, 1930, No. 996. [Class 100 (i).] In a braking-device for the web rolls of printing and other machines, of the kind comprising friction belts engaging the roll periphery and a pilot roller engaging the web, for automatically controlling the belts to maintain a constant predetermined tension in the web, manually-operated means are provided for taking up the slack of the belts as the diameter of the roll decreases. As shown, applied to an apparatus for supporting an active roll 14 and a reserve roll 15, each roll is provided with a braking-device comprising a number of belts 32 secured at their lower ends to pivoted arms 34, the upward movement of which is limited by adjustable stops 38, and at their upper ends to pulleys 39 fixed to a shaft 40 mounted in arms 41 secured to a shaft 42 provided with an operating- handle 47. A pinion 44 on the end of the shaft 40 meshes with a segment 45 whereby upon turning the shaft 42, the pulleys 39 are rotated to wind up or release the belts as desired. The segments 45 are idly mounted on the shafts 42 and are connected by links 58 to one of a pair of arms 54 carrying a pilot roller 50 around which the web passes so that movement of the roller 50 due to varying web tension operates the segments 45 to adjust the belts 32 to restore the tension of the web to normal. The roller 50 is held against the web by a compression spring 59 and by a helical spring on the shaft 57 carrying the arms 54, one end of the helical spring being secured to a collar fixed on the shaft 57 and the other end being fixed to a worm wheel 63 loose on the shaft and rotatable by a worm 64 and hand-wheel 65 to vary the spring tension and thus the normal web tension. The rolls 14, 15 are carried by arms 10 secured to a cross-shaft which may be turned to raise and lower the arms for the insertion of the web rolls by a quadrant 20 on the shaft and a hand-operated worm 21. The arms are adjustable on the cross-shaft to suit rolls of different widths and the cross-shaft is adjustable axially for side register of the webs by a screw 27, rotatable in the machine frame and threaded into the end of the cross-shaft.

摘要： 309,626. Goss Printing Press Co. of England, Ltd., and Smith, E. J. Jan. 13, 1928. Feeding webs.-In a web-renewing mechanism for a printing-press, the joining of the new web to the expiring web is effected by bringing the old roll and the new roll, to one of which paste has previously been applied, into contact. An active roll 1, Fig. 1, and a reserve roll 2 are mounted in pairs of arms 3 fixed to cross-shafts 4 provided with worm-wheel segments 20 engaged by worms 21 on coaxial shafts 22 the inner ends of which are provided with bevel wheels 24. A bevel-wheel 25, provided with an operating handle, is mounted on a centrally pivoted lever 26 which can be held by a pin 26 engaging either of two holes in the machine frame, so that the wheel 25 can be operatively engaged with either wheel 24 to press the new roll, previously provided with adhesive, into engagement with the expiring roll. Yielding pressure is provided for by permitting the worm shafts 22 to have a limited longitudinal movement against the action of springs 29, and this movement may be prevented when desired by inserting collars between flanges 31 on the shafts 22 and the adjacent hearings of these shafts. The arms 3 carrv short spindles 6, Fig. 4, having bung-like ends 7 to engage the ends of the roll core, and one spindle is slidably keyed within a rotatable sleeve 9 and is movable axially, to facilitate the insertion of the roll, by a lever 14, actuated by a screw 17, and carrying pins 13 engaging a grooved collar 11 on the spindle 6. Lateral adjustment of the rolls is effected by screw 32, Fig. 1, rotatable in the machine frame and engaging threaded bores in the ends of the shafts.4. Each sleeve 9 may be provided with a brake comprising a split friction ring 35 actuated by a screw 36, or with a brake band 52, Fig. 7, actuated automatically by the varying tension of the web. For this purpose, the web passes round a spring-mounted roller 37 and round a roller 38 mounted in guides 40 and connected by a link 41 to a bell-crank lever 42 fixed to a shaft 42b and connected by a link 43 to an arm on a shaft 45 carrying a pulley 46, to which are secured cables 47 connected to arms 51 on shafts 51a carrying arms 51 connected to the brake bands 52. A torsion spring on the shaft 42b urges the roller 38 against the web. As the tension of the web varies, the roller 38 is moved by or against the action of the torsion spring and increases or decreases the pull on the cables to apply or release the brakes and thus restore the normal web tension. To take up slack in the cables when the arms 3 are actuated, the cables are passed round jockey rollers 48 on arms 49 loose on the shaft 45 and having a slot connection with links 53 connecting the arms 49 to collars 54 moving with the shaft 4. The torsion spring on the shaft 42b is secured at one end to a collar fast on the shaft and at the other end to a loose worm-wheel 55 rotatable by a worm 56 for adjusting the tension of the spring.

摘要： 301,630. Smith, L. J., and Ashton, J. J. Nov. 14, 1927. Driving-gear.-In single or double acting steam or other gaseous pressure engines, the pistons of oppositely disposed cylinders or groups of cylinders are connected to opposite ends of a reciprocating carrier 12 which actuates a distributing valve and drives the main shaft 9 through a pair of nuts 13, 14 engaging crossed threads thereon and adapted to be held from rotation alternatively, according to the direction of the stroke, bv clutch engagement with bosses 33 on the carrier. The driving gear is arranged in an oil sump 10 in a chamber 8 to which the cylinders 6 are attached, the device as a whole being mounted in standards 7, the shaft 9 carrying flywheels 32. The actuating fluid is supplied through pipes 24 to a casing 22, the distributing valve 17, Fig. 4, having a diametrical tube 21 adapted to connect the supply alternately to pipes 25 leading to the cylinders. As one cylinder is charged the other is exhausted through its pipe 25 and an exhaust port 26 in the valve sleeve 17. The valve is operated by a cam 19 rocked by lugs or tappets 20 on the carrier 12. Adjustable stops limiting the rocking of the cam enable the valve openings to be regulated according to the pressure of the supply fluid.
