Title: Improvements in or relating to the manufacture of footwear
IPC: A43D119/00
Filed: 1932-11-02
Abstract: 392,084. Boot-making machines. BATA AKCIOVA SPOLECNOST, Zlin, Czecho-Slovakia. Nov. 2, 1932, No. 30838. Convention date, Nov. 2, 1931. [Class 17 (i).] Last supports for hand-work.-Relates to apparatus of the type wherein a series of carriages with lasts thereon are intermittently moved in succession from one operator to another along a track by mechanical means ; and consists in the provision of automatic means for adjusting the lasts on their carriages to positions convenient for the new operators. Each last carriage has a roller 36a engaging a channel rail 20 in the machine framework and a pair of rollers 32a running on a rail 19 The carriages are intermittently moved by an endless chain 1. Each carriage has a table 35 for supporting the materials required by the operator. The body 32 of the carriage supports a spindle 36 to which is keyed a spurwheel 37 normally locked against rotation by a pin 56 engaging one of four holes positioned 90 degrees apart in the wheel. A cross pin 41 in the spindle co-operates with four recesses 40 spaced 90 degrees apart in a member 39 keyed to a head 48 rotatable about the spindle, the members 39 being urged toward the body 32 by springs normally locking the head against rotation by pins 42 secured to the body and engaging holes in the member 39. This member is also engaged by a plunger 61 parallel with the spindle 56. The spindle 36 carries a bevel wheel gearing with another on a last spindle 50 on which a last is retained by a spring catch 52 provided with a roll 55 for retraction. At the operator's positions each spur wheel 37 comes to rest above the axis of a gear segment 64 which is then set in motion by a chain 2 to adjust the last into a position convenient for the new operator. The segment carries a cam 65 for withdrawing the locking pin 56 as the teeth come into mesh. For permitting the pin to lock the wheel before the segment has left the spur wheel, the last tooth 68 of the segment can yield against a spring. If the last is to rotate about the shaft 36 instead of about the shaft 50, the cam 65 is shaped to engage a second roll 60 actuating a plunger 61 moving the member 39 toward the last, this plunger having a pin 62a also moving the plunger 56. For conveying the carriages from one side of the machine to the other each of the main chain sprockets carries an annular member 26 formed to provide a support 26a for the rollers 32a and a channel 26b for the roll 36a. One of these sprockets is carried by a slide 30 adjusted to tension the chain by a screw engaging a nut and turned by a head 31. This adjustment also tensions the chains 2, but these are provided with supplementary adjusting means 29.

Title: Improvements in and relating to buttonhole sewing machines
IPC: D05B3/08
Filed: 1931-11-06
Abstract: 377,524. Buttonhole sewing-machines. HUGHES, R. M , 72, Cannon Street, London.-(International Button Hole Sewing Machine Co. ; 502, Harrison Avenue, Boston, U.S.A.) Nov. 6, 1931, No. 30851. [Class 112.] The supplementary devices such as thread pull-off and cutters are positively operated by a cam carried on the main driving shaft and actuated by the mechanism for controlling the clutch of the machine. The clutch 9 for actuating the machine is actuated by the manually controlled lever 15, rod 10, block 11 and bifurcated arm 12 in the usual way. The stop-motion bar 18, actuating the rod 19 and cam 20, are also controlled by the rod 10 in the usual way. The tl.read gripper 21 and thread trimmer 22, associated with the clamps 3, are both actuated after the machine has come to rest, through the medium of the cam 24 which is loosely mounted on a continuously driven shaft 25. The cam 24 is disconnected from the shaft 25 during the stitching operation but is clutched thereto to make one revolution when the shaft 7 and the stitching mechanism has come to rest. The cam 24 is clutched to the shaft 25 by a pin 27 normally held inoperative by the dog 28. The clutch dog 28 is positively released by a cam 34 which strikes a lug 36 on an arm 32. This engages the arm 31 of the lever 30, rocking the shaft 29 to raise the dog 28 and release the pin 27. The work clamps 3 are normally held in their raised position by a latch 37 on the arm 39 fast on a rock shaft 40. This shaft has another arm 41 actuated by the cam 24. When the cam 24 makes its single revolution. after the stitch-forming elements have come to rest, the rock shaft 40 causes the latch. 37 to make a to-and-fro movement, causing it to engage the lug 42 carried by the work clamp arm. This arm is then pulled backwards to raise the clamps. The latch 37 has a tail 44 engaged by a cam face 45 on an extension 46 secured to the block 18. When the driving clutch 9 is engaged by shifting the member 10, the cam face 45 engages the tail 44 of the latch 37 and raises the latch so long as the clutch is in driving position. The latch is released to allow the work clamps to close by a swinging lever 55 actuated by a connection 56 leading to the starting treadle.

Moulds for ice &c. blocks are .inverted for harvesting, valve means operating on inversion to supply warming fluid to free the blocks and, on restoration to the upright position, to supply coolant for a further freezing period. The moulds 39 of any suitable cross-section are mounted in staggered relation on a plate 36 bolted to an insulated trough 33 provided with baffles 40 and having hollow end shafts 29 working in bearings 28. The shafts extend into valve chambers 27 and carry cams 58, 62 actuating valve rods 55, 61 carrying spring-loaded poppet valves 54, 60 which are opened and closed alternately as shafts 29 are rotated through 180 degrees. When the moulds are upright, valve 54 is open and cold brine from a storage tank 17 is circulated by a pump 19 through an evaporator-cooler 16 and a pipe 46 to the trough 33. From the trough it passes back to the tank 17 through a pipe 51. When freezing is completed, the trough 33 with the moulds 39 are tipped up by handles 63 and this closes valves 54 and opens valves 60. Brine from a tank 20 warmed by the refrigerant condenser is forced by a pump 23 through a pipe 48 to the trough and returns to tbe tank 20 through pipe 52. The thawed-off frozen bodies are deposited on a tray 26. As shown in Fig. 6, two trough units working in antiphase are provided. When the valves are changing over, the discharge valves change rather later than the entry valves so that time is allowed for residual cold or warm brine as the case may be to be discharged from the trough to the tanks 17, 20 respectively. Different heating and freezing liquids or fluids may be used. The troughs may be tipped up automatically and be held in extreme positions by detents. The discharged bodies may be caught in trays carried in a space 42 above the moulds.

Title: Photographic type-composing apparatus
IPC: B41B17/10
Filed: 1972-07-04
Abstract: 1389086 Photographic type-composing ASAHI KOGAKU KOGYO KK 4 July 1972 [8 July 1971] 31292/72 Heading B6W A plurality of (e.g. four) rotatable character discs 1-1 to 1-4, Fig. 6, are mounted on a common shaft in spaced relationship, each disc carrying transparent characters arranged in four concentric rows and being aligned to form radial columns aligned with flash timing members. At any given time therefore, four characters on each disc, e.g. 3-11 to 3-14 on disc 1-1, Fig. 4, 3-21 to 3-24 on disc 1-2, &c., are passing through an exposure zone defined by a plurality of prisms 11-1 to 11-5. At the instant when a selected character, among others, is in the zone, a flash light source is ignited, and light therefrom passes as sixteen beams through light guides 10 arranged in four rows of four, guides 10-11 to 10-14 being outside the disc 1-1 and the other guides being between the discs, Fig. 6. The beams passing through guides 10-11 to 10-14 parallel to the discs are reflected by prisms 11-1, 11-2 to pass through the characters and return to a parallel path on the other side of the disc. Beams from guides 10-21 to 10-24 are reflected by prisms 11-2, 11-3, &c. The beams are then reflected by microns 12-1 to 12-4 and each beam passes through an objective 6, the sixteen objectives forming a four by four matrix, Fig. 3. The beams from the respective rows of objectives, namely 6-11 to 6-14, 6-21 to 6-24, &c. are reflected by respective mirrors 7-1 to 7-4, arranged in one plane, and beams from any of the mirrors 7 pass, when not obscured to four mirrors 8-1 to 8-4 and thence to a projector lens 9. In the full line position of the mirrors 7, 8 in Fig. 3, only the beam from character 3-11 reaches the lens 9, because beams from mirrors 7-2 to 7-4 are cut off by at least mirror 7-1, while beams from mirrors 8-2 to 8-4 are cut off by at least mirror 8-1. In order to select a character other than 3-11, one or more of the mirrors 7-1 to 7-3 and one or more of the mirrors 8-1 to 8-3 are moved out of the optical path to the chain line positions in Fig. 3, a preliminary selection of a group of sixteen characters having been made by igniting the light source in response to photo-electric sensing of the timing marks. Other optical devices in the path from the lens 9 to the film accomplish -variation of magnification or other functions.

Title: Improvements relating to the control of selecting switches such as used in automatictelephone systems
IPC: H04Q3/42
Filed: 1930-10-20
Abstract: 361,071. Automatic exchange systems. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, and PATTERSON, W. G., 68, Eltham Road, Lee, both in London. Oct. 20, 1930, No. 31401. [Class 40 (iv).] In bi-directional group selectors which are set under the control of relays in a common control circuit, the release magnet is controlled directly over the test wire. In one arrangement, the release magnet is connected to the test wire when the switch moves off-normal and is short-circuited by the holding potential. A single individual relay when operated associates the switch with the control circuit and when released switches through the connection. In a second arrangement for use in a register-controller system, the switch restores on the relapse of the release magnet, which energizes over the test wire when the switch is taken into use. No individual relays are provided, and the connection is switched through at the preceding first selector. Specification 263,514, [Class 40 (iv), Telephones &c.], is referred to. First arrangement, Fig. 1. Relay C energizes over the c wire when the selector is seized and connects relay X in series with itself, thus marking busy the control circuit and the associated selectors. Impulse relay A energizes over the incoming b wire, connecting up sluggish relays V, D, and impulses are repeated to the vertical magnet VM at contact a1. Relay P pulls up at the first impulse and relay D holds at back contact a3 until the end of the train, and then falls back and closes the hunting circuit for the rotary magnet RM. Test relay T upon operation opens the holding circuits of relays C, X to complete the connection and release the control circuit, while a circuit exists over off-normal contacts k for the release magnet ZM, which however is short-circuited over the test wire as long as the conversation continues. Second arrangement, Fig. 2. When the selector is seized, the back-acting release magnet ZM energizes over the c wire and connects relay ST in series with itself, marking busy the control circuit and the associated selectors and connecting up sluggish relay D. The magnet DM advances the associating switch into engagement with the selector, and relay TC energizes. Impulses are received over the b wire by relay A and are repeated to the vertical magnet VM at contact a1. Relay P pulls up at the first impulse and relay D holds at back contact a2 until the end of the train, and then falls back and closes the hunting circuit for the rotary magnet RM. Test relay T upon operation causes the relapse of relay ST to release the control circuit, but the release magnet ZM remains locked throughout the conversation over rotary off-normal contact w1. The talking connection is completed by the operation of relay WC at the preceding selector when all the impulse trains have been sent.
