Title: Improvements in or relating to machines for operating upon heels
IPC: A43D87/00
Filed: 1936-09-05
Abstract: 481,168. Trimming heels. BRITISH UNITED SHOE MACHINERY CO., Ltd., HAZELTON, G., and JAMES, C. H. Sept. 5, 1936, No. 24270. [Class 17 (i)] A machine for trimming unattached heels comprising a cutter, a jack including rotatable heel-clamping means, and template means for controlling the aspect of presentation of the heel and cutter during trimming, is provided with means for ejecting a trimmed heel from the clamping means and with heel-clamping members and templates so mounted as to be quickly replaceable by others of a different size or shape. The improvements are described as applied to the machine described in Specification 411,448. The member 3 for engaging the heel tread face is formed as a metal plate, instead of a rubber pad, on a stem 37 which is secured in the sleeve 39 by a screw 41 and keyhole slot. The tread endlocating member 27 is secured by a tongue and groove and by screws 57 and keyhole slots to the member 45, which also has openings giving access to the screw 41. The fibre block 5 for engaging the attaching face of the heel is secured by a metal slide member 63 to the sleeve 69 and is locked in position by the spring-pressed plunger 35, the latter being retractible by means of the stem 131. The shafts 71 and 73 are connected by a piece 75, and are relatively adjustable by means of flanges 81, 85, to allow slight adjustment of the angular position of the plate 3 and block 5. The template 21 comprises a fixed portion 97, Fig. 4, formed on the sleeve 99 keyed to the shaft 71, and a major portion 103 which is a sliding fit on the portion 97 and is secured in position by pins 111 on a clamping member 105. Thus, the portion 103, which controls the aspect of presentation of the heel to the cutter, is readily replaceable. The template 23 is formed similarly of a fixed portion 113 and a replaceable portion 117 held in position by clamping members 119, 121 and screws 125. Each fixed portion 97 and 113 is formed with a notch 95 co-operating with a roll 91 to assist in indexing the jack in stopping position. The clamping handle 25 is spaced to the left of the block 5 to provide room for a resilient mounting for the sleeve 69. The latter, on which the gear-wheel 19 is keyed, is urged to the left by a spring 153. It is moved to the right, to clamp a heel, by cam surfaces, on a collar 171, acting through compression springs 177. The handle 25 is secured to the collar 171. By this arrangement, a longer clamping movement is imparted to the block 5, and the latter is moved by the springs 177 to release the heel when the handle 25 is released. The heelejecting arrangement consists of a finger 191 which is urged by springs against the heel breast. To facilitate ejection, the member 27 is held against return to its normal position of rest by a catch 199, which is only released at the end of the return of the lever 25 to its inoperative, unclamping, position.

Title: Comminution process and apparatus
IPC: B29B13/10
Filed: 1954-08-23
Abstract: <PICT:0788542/IV (a)/1> In a process for comminuting a solid synthetic resin which is too tough for ready comminution at normal or room temperatures, the resin is introduced into a bath of a liquid cooling agent arranged in advance of a comminuting device, is allowed to remain in the bath until it is brittle, and is then passed through a liquid seal adapted to prevent access of external air, the embrittled substance finally being directly fed to the comminuting device. Examples given of resin to be comminuted are thermoplastic resins, e.g. polyethylene, polyisobutylene polyvinyl chloride and other polymers, and poly-addition products such as polyurethanes,. The cooling agent e.g. liquid air or liquid nitrogen, is preferably applied at a temperature between -80 and -200 degrees centigrade. Apparatus for carrying out the process comprises a chamber 5 containing a bath 4 of liquid cooling agent into which the tough material is introduced from a supply vessel 1, the chamber 5 being provided with a screw conveyer 8 which carries the material, after it has been rendered brittle by the cooling agent, into a comminuting device 13 and the bath 4 and conveyer casing 7 being so inclined relative to each other that the bath 4 forms a liquid seal.  The supply of liquid cooling agent from a vessel 2 to the chamber 5 is controlled by a valve 9.  Gases evolved from the chamber 5 may be (a) sucked off by means of a fan 10 to pre-cool the tough material, and (b) conducted, by means of a valve-controlled blowing conduit 20, through a conduit 11 and a pipe 12 into the comminuting device 13 to cool the latter.  The powder from the device 13 is fed from a funnel 17 into a collector 18 and is blown through the conduit 20 into a filter bag 21 and collected in a container 22.
