Title: Apparatus for processing frozen comestibles
IPC: A23G9/22
Filed: 1960-02-12
Abstract: 866,348. Kneading ice-cream. REED, C.A. Feb. 12, 1960 tFeb. 13, 1959], No. 5083/60. Class 86 In an apparatus for kneading and plasticising hard frozen ice-cream and the like, the ice-cream is placed in a hopper 52 in which it is kneaded, and from which it is extruded, by a helically flighted auger 44 which consists of a tip 46 which is separable axially from the main part of the auger, against the force of the spring 41, so that, as the hopper is thrust upwards on to the auger, the hard icecream is engaged only by the tip 46 whilst the main body of the auger yields axially until the spring pressure gradually brings the whole of the auger into operation. In this way premature extrusion of unkneaded ice-cream is avoided. The tip 46 is secured to a shaft 36 screwed at 35 into a shaft 30 driven by a motor 29, the shaft 30 being splined to drive a slidable sleeve 39 having a pin and slot 43 driving connection with the main part of the auger. The hopper 52 is guided for vertical movement on rods 47, 48, and a door 17 slides vertically with the hopper so that the operator can place a container for the extruded ice-cream under the hopper 52. The door 17 has a pivoted flap 21 carrying a roller 116 which, when the flap is closed, lies immediately over a roller 58 carried by the door 17. The hard ice-cream is wrapped by a strip having a projecting tag which is grasped by the operator who presses the ice-cream against and through the flap. The flap then closes leaving the tag still held by the operator who pulls it between the rollers 116, 58 and strips it from the icecream which falls into the hopper. Nuts, flavouring may now be added through the flap. The hopper is raised by a handle 63 on a shaft 61 which is rotated thereby between stops 62a, 62b, the shaft carrying a sprocket 65 connected by a chain 74 with a sprocket 72 on a shaft 69. Scroll shaped drums 75, 76 are secured to the shaft 69 and are connected by cables 83, 84 with a cross-head 51 carrying the hopper 52. The scroll drums are shaped so that the initial approach of the hopper to the auger is fast and becomes progressively slower as the auger penetrates more deeply into the ice-cream and the load increases in consequence. Return cables 92 are attached to the scroll drums and pass under pulleys 83, on spring-pressed fixedaxis arms 85, to be attached to the cross head 51. When the handle 63 is pulled by the operator, an arm 99 swings towards the lever 98 of a micro-switch 95 in the motor circuit, so that the auger is rotating before contacting with the ice-cream. The arm 99 is frictionally held on the shaft 61 to permit slipping when the switch is closed and the handle 63 is moved further to complete the use of the hopper. A spring 108 tends to move the arm 99 towards the switch and to counterbalance the weight of the hopper assembly. When the extrusion has been completed and the operator starts to move back the handle, the arm 99 is removed from the switch lever 98 and the motor stops.

Filed: 1942-04-16
Abstract: 556,754. Partition walls. WRIGHT, G. C., and GYPROC PRODUCTS, Ltd. April 16, 1942, No. 5086. [Classes 20 (iii) and 20 (iv)] Steel studs 12 for the framing of a partition wall are of channel shape, connected in pairs by bolts 14, and are received at their lower ends in saddles 18 formed of sheet steel plates which are bent upwards and outwards at 19, 20 and downwards at 22. A rectangular aperture 22 is cut in the channel to accommodate the stud 12. A similar but inverted bridge piece 18A is spaced from the saddle by wood blocks 28, and the flanges of the two members 18, 18A secure a skirting 25 of pressed steel, the upper edge of which is arranged to receive the wall panels 11. A steel channel 16 is fixed to the ceiling to receive the upper edge of the panels, and is spaced from the upper ends of the studs to avoid loading the latter by deflection of the floor. The studs are arranged so that they do not coincide with the vertical joints between panels, which may be formed as described in Specification 556,753. Fig. 7 (not shown), illustrates the arrangement at a corner formed by the meeting of two walls, and also the association of a door frame as described in Specification 556,752 with the wall.
Patent GB-612814-A (GB)
Title: Improvements in or relating to change speed gears for bicycles and the like
IPC: B62M9/1246
Filed: 1945-03-01
Abstract: 612,814. Change speed chain gearing. DALLIMORE, C. J., and WILLIAMS, G. March 1, 1945, Nos. 5133 and 12909. [Class 80 (ii)] In a change-speed chain gear for bicycles and tricycles having low- and high-speed sprockets alternatively driven from a driving chain which is moved transversely by a fork member to engage either sprocket, the horizontal operating movement of the fork is effected by back-pedalling. As shown, a fork 19, Fig. 1, normally lying out of engagement with the driving chain 22, is movable under the action of a push-rod 28, first rotating to engage the chain 22 and then traversing horizontally to move it from one to the other of the low- and high-speed sprockets 3, 4 respectively. The push-rod 28 is operated by a pin 30 on the chain-wheel 29, which coacts with a gravity or spring-loaded lost-motion arm 31 pivoted as shown in Fig. 5 on a lever 32, itself pivoted on the bicycle frame. A pin 34 on the end of the lever 32 engages with spring-loaded frictional damping a slot in the push-rod 28 which on back-pedalling is thus moved rearwards from the position shown in Fig. 1 until it has moved sufficiently for the pin 30 to clear the arm 31. The rear end of the push-rod 28 carries a pin 11 guided in a slot 12 in a fixed frame plate 7. Pivoted on the pin 11 are an arm 20 and a pawl 13. The arm 20 is connected to the fork 19 pivoted in the frame plate 7 and controls its rotation, whilst the pawl 13 coacts with ratchet teeth 14 on a rotatable cam plate 15 also mounted on the frame plate 7 and controls the horizontal movement of the fork 19 through a cam track 16, Fig. 3, on the plate 15 against which track the outer end of the spindle 17 of the fork 19 is spring biassed. After a speed change has been effected, forward pedalling is resumed, the pin 30 then moving the push-rod 28 forwards so rotating the fork 19 out of engagement with the chain 22 and causing the pawl 13 to pick up the next tooth of the ratchet 14 ready for another change. The members 28, 32 may be of spring steel or other resilient material, and the levers 31, 32 may have spring-biassed slotted connections with their pivots. In a modification, the fork 19 is operated as before, but from a pin disc rigid with the sprockets 3 and 4 instead of from the chain wheel, the push-rod 28 being replaced by a direct lever system, and the action of the pin in picking up the lost-motion arm being rendered more positive by a friction weight device.
