Title: Improvements in devices for producing proofs in type-bar making machines
IPC: B41B11/00
Filed: 1932-07-29
Abstract: 389,362. Type-bar-making machines. GJAERDER, A., 48, Mollergaten, Oslo, Norway. July 29, 1932, No. 21439. [Class 100 (iii).] Proof-taking apparatus.-In apparatus for taking proofs in type-bar-making machines, of the kind wherein directly outside the type-bar delivery channel a paper strip is arranged and supported by a yielding platen to receive the impression directly, or through ink ribbon during the motion of the type-bar between the delivery channel and the galley, the platen is so arranged at a short distance from the mouth of the delivery channel that it is struck by the type-bar during the first part of its travel out from the channel, and is pushed completely or partly back thereby during impression, the platen being maintained in a withdrawn position allowing the succeeding endwise motion of the type-bar into the galley. The type-bar 2 in its passage from the delivery channel 3 to the galley 4 strikes against an ink-ribbon 7 and presses this against a paper ribbon 6 which passes over a yielding platen 5. The paper-feeding mechanism, ink-ribbon, and platen are carried by a frame 8, which under the pressure of the type-bar slides back in stationary guides 11, 12 against the action of springs 34, 35 until a pin 26 on the frame 8 engages beneath a spring hook 28, when the whole is held stationary in its withdrawn position to allow the type-bar to move sidewise into the galley 4. The frame is then released to move back into its proof-taking position by a projection 42 on a periodically moved member such as the elevator 43, which rotates a bar 40 through a lever 41, and thereby causes an arm 37 to swing the hook 28 to the left to release the pin 26. During this upward movement the paper is advanced by the pawl-andratchet mechanism 19, 20, while the ink ribbon 7 is advanced by a mechanism similar to that used in typewriters. One side of the frame 8 carries a bar 30 which slides in a fixed guidebolt 31 and is provided with nuts 32, 33 for adjusting the position of the platen relative to the channel 3. In a modification, the frame is held frictionally against movements in the backward direction until the pressure of the type-bar becomes excessive, when the frictional resistance is overcome ; the completion of the backward movement and the ensuing forward movement is effected by a rod attached to one end of the frame actuated through linkage from a cam surface carried by the elevator 43, which causes the frame to move back more quickly than the type-bar is ejected so that the latter may move sideways to the galley. The pressure of the type-bar may be assisted by a rod which moves with the mechanism ejecting the type-bar and presses against a projection carried by the frame as soon as the proof has been effected, the retraction of frame being assisted by a tensioned spring. The ratchet feed for the paper strip may be adjusted to vary the length of paper fed at each reciprocation.

Title: Method of and apparatus for insulating the carbon dollies of electrical dry batteries
IPC: H01M4/10
Filed: 1929-07-18
Abstract: 337,001. Bumke Ges., H. A. April 8, 1929, [Convention date]. Electrodes.-Dollies for dry cells, i.e. the linen or like sacs containing a carbon and surrounded by powdered carbon and graphite, are carried by a conveyer having a step-by-step movement past a dipping bath, where their lower ends are coated with insulating composition. In the apparatus shown, the dollies 16 are inserted in cylindrical receptacles 15 mounted on a conveyer belt 14, and are carried over a hopper 18 into which they fall and from which they are delivered into apertures 3 in a rotating disc 1. A plate 17 beneath the lower run of the conveyer prevents the dollies falling from the receptacles 15 until they are over the hopper 18. The driving mechanism imparts corresponding step-by-step movements to the conveyer 14 and the disc 1 through a pawl- and-ratchet mechanism 36, 37 and an eccentric pin 10 which engages teeth 4 on the edge of the disc. On entering the hole in the disc, the dolly rests on a stop beneath the latter and is thus positioned vertically. As the disc moves on, a spring-pressed bolt 21, Fig. 3, previously retracted by a cam 23, moves forward and clamps the dolly in position in the aperture. As each dolly arrives in position over a bath 25 of molten insulating composition a dipper 27 carried by a vertically reciprocating slide 30 rises and coats the lower end of the dolly with the composition. When the dipper has fallen, the dolly is carried on over a heated stop 34 which smooths the lower face. The dolly is finally discharged as the bolt 21 which retains it is again retracted on reach. ing the cam 23.

Filed: 1955-08-02
Abstract: 780,829. Coiling. SLEEPER & HARTLEY, Inc. Aug. 2, 1955, No. 22131/55. Class 83 (4) A wire coiling machine having coiling tools comprises relatively separable feed rolls arranged to grip a wire therebetween and feed it to the tools, power mechanism for driving the rolls, cam mechanism including a lifting cam and follower which separates the feed rolls and stops the wire feeding, and a holding cam and follower operating in timed relation with the lifting cam which hold the feed rolls separated after the lifting cam has functioned. Wire 7 is fed by driven rolls 1, 2 to a coiling tool 11 and when sufficient wire has been coiled the upper roll 1 is lifted to stop the feed and the coil severed from the wire supply by one or other cutters 14. Wire feed; shearing adjunct. Wire is fed by the rolls until a compound cam 38, 39,. adjustable on a shaft 40 driven slowly through interchangeable gearing from the roll shaft 4 of the roll 2, moves a yoke 27 and ring 25 axially of the shaft 4 to a position beneath a lifting cam 21 on the shaft 3 of the roll 1. The cam 21 then lifts the roll 1, pivoting the shaft 3 about a bearing at its other end, thus stopping the wire feed. By the time the high part of the cam 21 leaves the ring 25, an adjustable two-part holding cam 50 on the slow shaft 40 has moved to lift a roll housing 55 for the roll shaft 3 to hold up the roll 1. During this period a cam 100 on the shaft 40 rocks, through lever-means 103, 105, a support shaft 16 for a cutter 14 to sever the wire from the supply. The cam 38, 39 meanwhile moves the ring 25 to a position between the lifting cam 21 and a lowering cam 20 on the shaft 3 and then to a position beneath the cam 20 so that a high part on the cam 20 supports the roll 1 as the cam 50 releases it, the cam 20 then lowering the roll to commence the wire feed. The ring 25 is then moved by the cam 38, 39 to a position between the cams 20, 21 to allow the wire feed to continue. To vary the diameter of the coil, the coiling tool 11 is moved in or out by means of a cam 133 on the shaft 40 rocking, through adjustable link means 135, 136, 132, 131, an arm 12 connected to a support 110 for the tool 11. To vary the pitch, a cam 150 (not shown) on the shaft 40 moves, through similar connecting means, a pitch tool 13 engaging the wire behind the first coil. Specifications 476,370 and 528,499 are referred to.

Title: Improvements in or relating to stapling-machines
IPC: B25C5/02
Filed: 1922-08-18
Abstract: 206,934. Wade, H., (Boston Wire Stitcher Co.). Aug. 18, 1922. Stapling, hand tools for.-A stapling-machine for fastening together sheets of paper to a greater thickness than possible hitherto without buckling the staple, is provided with a resilient worksupport for holding the sheets to be stitched in an elevated position, above the clinching means, so that the staple-driver inserts the legs of the staple completely through the work before they are clinched on a fixed anvil. Where a spring- mounted staple-driver is used the work-support offers greater resistance to the driver towards the clinching position than the retracting means, to ensure complete insertion of the staple legs through the work before the support moves downwards. Preferably the support is an arched apertured plate. The invention is shown embodied in a machine as described in Specification 206,932 but is applicable to all types of stapling-machines. A work support 90 of thin sheet metal is welded at one end to a base plate 2, and its free end is curled upwards at 94, so as to slide thereon. The work-support is perforated at 95, for the passage of staple legs through the work p. The staple legs are finally clinched on an anvil 70, after passing completely through the work, the support 90 then being pressed flat on top of the anvil. Full details of the machine described in Specification 206,932 are given in this Specification. The machine is made of sheet metal, comprising a base 2, and a stapling-arm 3, hinged at 6, to ears 5, on the base. The arm 3, comprises side plates 7, and a core 15 on which finished staples s are fed by a pusher 12 actuated by a coil spring 11 attached to a hub 55 supported in side plates 22 on the arm 3. The driver 30 is made of sheet metal with a sheet-metal handle 33 and runs in grooves 32 at the forward end of the arm 3. The stapling-arm is normally held raised by a spring 75.

Abstract: 1,114,492. Boots &c. MASCHINENFABRIK MOENUS A.G. 27 May, 1965, No. 22595/65. Heading A3B. [Also in Division B4] In a machine for edge working a shoe sole the sole blank 30 is held stationary in the machine and a milling cutter 22 is moved around the sole blank. The milling cutter 22 is carried on an arm 24 which is mounted on a pivot 20 on a ring 8, the cutter being urged against the sole blank by a spring 26. The ring 8 is rotatably mounted in a slide 4 and is rotated by a motor 14 through gears 16, 18, 12. The ring 8 also carries an eccentric disc 10 which engages a roller 40 on a lever 44 which is pivoted to the slide 4 at 42 and to the machine frame at 48, the rotation of the disc 10 causing the slide 4 to be reciprocated. The combination of the linear motion of the slide 4 and the rotary motion of the ring 8 causes the pivot 20 to move around the sole in an approximately elliptical orbit 32 (Fig. 2) the milling cutter being urged into engagement with the sole blank by the spring 26. The length of the orbit can be adjusted in accordance with the length of the sole by moving the position of the pivot 42 or the pivot 48. In a particular embodiment (Figs. 4, 5, not shown) sole blanks 30 are stacked in a magazine (54) where they are moved by a thrust bar (82) to a working station where they are held between a hold down foot (94) and a thrust plate (96). The milling cutter 22 then moves around the sole blank as described above and the completed sole is ejected as another sole blank is fed to the machine by a parallelogram link (105) on a rod (84) connected to the thrust rod (82).
