Abstract: 220,114. Edmonds, O. D., and Sennitt, E. A. June 18, 1923. Switches, quick-action. - A multiple two-way switch, applicable to wireless telegraph or telephone circuits and of the kind comprising a movable contact member caused to contact with either of a pair of fixed contacts situated one on each side of the movable contact, has the arrangement within a suitable body of a plurality of pairs of fixed contacts and a. plurality of movable contact blades or plates projecting from plungers adapted to be slid along parallel axes in the body. The plungers are moved against spring action by a. rotary cam engaging the ends, the cam being so formed that, according to its angular position, the plunger contact blades contact with the one or the other of the fixed contacts of the appropriate pair in various combinations. The body a has a cover band contains insulating blocks c, d carrying fixed contacts e, f, each of which is secured by a screw passing through the body a from the outside where the leads are attached. Plungers h, carrying flexible blades j, are adapted to be slid so tha.t the blades j contact alternatively with the fixed contacts e, f, and each receives one end of a spring m the other end of which abuts on a fitting k to which a lead is attached. Each plunger further carries a seating n against which bears a ball o co-operating with apertures q, Fig. 8, in a rotary cam disc p, the arrangement being that in one position of the cam both balls will enter the apertures q in the cam and the blades j will engage the contacts e, and in another position neither ball will enter the apertures ,and the blades j will engage the contacts f, while in the third position only one ball will enter an aperture and the corresponding blade will engage the corresponding contact of the pair e and the other blade j will engage the other contact of the pair f. Thus the leads at k may be connected to the appropriate contacts e, f, the position being indicated by a line 11 on the operating knob y and by the Sguces on the cover b. The hub T of the cam p extends into a boss s on the cover b and is slotted to receive dog teeth on the knob y, one of which is elongated to engage a cut-away part of the boss s to limit the travel of the knob y. The number of plungers and contacts may be increased to produce a greater combination of contacts. According to the Provisional Specification, each fixed contact may consist of a piece of brass or like metal which constitutes a guide for a short spring-pressed button adapted, if necessary, to yield to ensure good contact.

Filed: 1961-05-03
Abstract: 966,565. Machine tool details. WAVIS ENGINEERING DEVELOPMENT CO. Ltd. May 2, 1962 [May 3, 1961], No. 15958/61. Headings B3C, B3K and B3N. [Also in Division F2] A drilling, reaming, tapping, milling &c. head comprises a tool spindle driven by an electric motor and a feed nut driven by a separate motor, the spindle and nut being driven at differential speeds. Ths head comprises a twopart spindle 121, 122 pinned together, which is driven from an electric motor 19 through a belt 18 and pulleys 191, 17. A second electric motor 24 rotates a feed nut 26 by gears 241, 23, 22, 21 and the nut co-operates with a lead screw 27 pinned to spindle part 121 at 271, the motors being connected by a magnetic clutch 25. Adjustable dogs 310-312 are carried by a rod 30, fixed to spindle part 122, and co-operate with plungers 320-322 for tripping microswitches 33 for controlling the motors. Lead screw 27 is threaded in the opposite direction to the rotation of the spindle and, as nut 26 is rotated a rapid approach to the work of the spindle is effected. Dog 310 actuates switch 33 to switch on motor 19 which rotates the spindle at a lower speed than nut 26, consequently the feed continues at a lower rate. When the operation is completed dog 311 causes motor 24 to stop, and a rapid return of the spindle is effected. Dog 312 then causes motor 19 to stop and the head is ready for a further cycle. The motors are coupled by clutch 25 when both are rotating and as feed screw 26 requires less power than the spindle the excess power from motor 24 is used for driving the spindle during cutting. The drives from the motors may be by gears or belts.

Title: Improved method of producing paper containers
IPC: B31B17/00
Filed: 1937-06-11
Abstract: 488,752. Making conical paper containers. PERCIVAL, S. (Jagenberg-Werke Akt.-Ges.) June 11, 1937, No. 16256. [Classes 18 and 66] Conical paper containers with separate dishshaped bottoms are made from blanks z, Fig. 17a, fed by bands 44, Fig. 16a, from a magazine to a conveyer band 48 which is passed over guide rollers 49, 50, 51, Figs. 16a and 16b, by bevel gears from a main shaft 43. Spring rolls 52, 53 adjust the tension. Guide rails 54, 55, Fig. 20, and a roller beam 56 serve to guide the blanks past a gluing dish 58 in a glue tank 57 which places a strip of glue parallel to the lateral edge. One edge of the blank is then gripped by discs 61, 63 moving slightly slower than the conveyer so that the blank is turned to bring folding line c into the direction of movement of the conveyer, one lateral edge of the blank then engaging a folding rail 66 which bends it as indicated in Fig. 20. Next the other lateral edge is similarly delayed and folded by a rail 67. Folding belts 68, 68<1>, Figs. 16b and 17b, then fold the edges of the blank entirely down, after which the blank is pressed by rollers 71-78, a roll 89 serving to bring the blank into alignment with the direction of the conveyer. The tubes thus formed are delayed and spread by rolls 90, 90<1> which produces a nesting of the tubes ; then, passing between rolls 101, 101<1>, Fig. 17c, and 103, 103<1>, they are recollapsed in a direction perpendicular to the original direction. The tubes are then again opened by rolls 104, 104<1>. The blanks may also be arranged with the longer edge forwards. A circular dished bottom is inserted by a plunger which may be arranged as in Fig. 14, a form block 31, jaws 34, elastic rubber &c. lining 35 and arms 36 being employed in known manner. The final joint may be as in Figs. 11 or 13, the joint being glued or the container wax impregnated.

Abstract: 1425900 Unwinding textile material; weft measuring; shuttleless looms SULZER BROS Ltd 5 April 1973 [28 April 1972] 16331/73 Headings DIE and D1J A stationary cylindrical store 9, Fig. 1, is orbited by means 6 that winds textile material 21 onto the store, there being brake means 14 at the outlet from the store that acts on the material 21 from the inside of a balloon 31 formed during unwinding, and an annular balloon limiter arranged to act on the material from the outside of the balloon. In Fig. 1 the braking means is a ring of bristles 14 directed against a balloon limiter ring 16. The store or drum 9 is rotatably mounted on a rotating stub shaft 8 but is held against rotation by a permanent magnet 11 in the frame 1 and a permanent magnet 12 fastened in the drum 9. The winding 28 is monitored by a photoelectric control device 27. When the winding exceeds a given axial length, the control device 27 stops the drive of the shaft 4 so that as the unwinding of the thread 21 progresses off the store or drum 9 the length of the winding 28 decreases again. The drive of the shaft 4 is then restarted so that more thread is wound onto the drum. Fig. 2 (not shown) shows how the balloon limiter 16 is axially adjustable relatively to the bristles 14. Fig. 3 (not shown) shows how there may be an axially adjustable ring (37) within the ring of bristles 14 so that the bristles 14 can be supported, particularly in the region of their tips 17 to produce an increased braking effect. In Fig. 4 (not shown) a ring of bristles (15b) is arranged such that the bristles are directed radially outwards. A balloon limiter 16 causes the thread 21 to engage these bristles (15b) as well as a bead member 13 that is downstream of the bristles (15b). In Fig. 5 (not shown) the balloon limiter is a ring (42). This ring may be stationary or it may rotate with the drum 9. In Figs. 6 and 7 (not shown) the balloon 31 is braked by a flow of fluid. The fluid is directed against the interior of the balloon from apertures (52) in the periphery of an annular element (51). The fluid may be caused to swirl in a direction opposite to the direction of rotation of the balloon 31. The supply of fluid may be controlled in rhythm with the unwinding of the material. The fluid may be air or liquid. In Fig. 8 (not shown) the bristles 14 are replaced by an air-inflated tube (57) that bears against the inner surface 32 of the balloon limiter 16.

Title: Improvements connected with mechanism for the feeding of sheets to die relief stamping press
Filed: 1948-06-19
Abstract: 647,677. Platen printing machines ; feeding sheets. CURRIER & SON, Ltd., S., and CAMPLIN, C. NOBLE-. June 19, 1948, Nos. 16516 and 16518. [Classes 100 (i) and 100 (ii)] Sheets are fed to die relief stamping presses by a reciprocating carriage member which traverses the lay of the press to feed a sheet thereto and release it therein, and means interconnected with the member is adapted to position the sheet in the lay. Air suction means retaining the registered sheet in the lay, prevents the stamping operation if a sheet is not in the lay. A known air suction means 6, guided in a slot 9, carries a sheet from a pile 7 to a pair of jaws 10, 14 on a carriage 12 slidably mounted on a chain housing 13. The jaw 10 is fixed on a tubular member 11, and the jaw 14 is secured to a rod 15 slidable within the member 11 against the action of a compression spring 16. A rod 21 carrying a roller 22 adapted to co-operate with fired cams 23, 25, abuts the rod 15, whereby the jaws 10, 14 are opened to receive and release the sheet. A sleeve 27, pressed away from a fixed collar 26, by a torsion spring 31, into contact with a further fixed collar 17, has an extension 28 on which is pivoted a twoarmed lever 29, 30. The arm 30 is arranged below the collar 26 and is adjustable by a screw 32, and the arm 29 carries a pivoted extension 33 having a resilient pad, brush, &c, 34 thereon. A stop 35 lifts the extension 33 at position A. When the carriage 12 moves to position C, the cam 25 depresses the rods 21, 15 to release the sheet in the lay 24. The collar 17 is also depressed to allow the extension 33 to drop into contact with the sheet, and on continued travel of the carriage 12 to the right, a stop pin 36 (not shown) on the sleeve, 27 abuts a fixed stop 37 to swing the sleeve lever 29, 30 and extension 33 around the member 11 against the action of the torsion spring 31. The released sheet is thus pushed by the extension 33 to register against two lays 39, 40 (not shown), arranged at right-angles to each other. The registered sheet is held by a suction box 50 disposed beneath the lay 24 during stamping by a die 41. Tripping &c. arrangements.-Means whereby the die 41 is rendered inoperative if' a sheet is not in the lay 24, comprises a vacuum bellows, connected to the suction box 50, controlling a switch in an electric circuit which controls the operation of the die. A second switch in the circuit is operated automatically by a cam, and 'when both switches are closed, a solenoid is energized to prevent operation of the die. If a sheet is not in the lay 24, the vacuum pump cannot create a vacuum in the piping to the box 50, the bellows cannot be contracted to open the switch connected thereto, and so the die 41 will not be operated. Specification 601,689 is referred to.
