Title: Improvements in and relating to methods and apparatus for use in the remoulding of pneumatic tyres
IPC: B29D30/54
Filed: 1954-09-22
Abstract: 812,908. Remoulding tyres. BARWELL RUBBER CO. Ltd., BARWELL, J. H., and LANHAM, D. J. Sept. 12, 1955 [Sept. 22, 1954], No. 27434/54. Class 87(2). Pneumatic tyres are remoulded by the direct application to a prepared tyre carcass of camelback strip in hot, tacky condition, as it emerges from the extrusion head of a press which produces the strip. The tyre 25 which is to be re-treaded is slipped over two parallel horizontal rollers 26 and the end 62 of extruded strip rubber 23, in the tacky plastic condition in which it issues from the extrusion machine 21, is applied to the tyre, which is rotated to wind on the strip. The extruded strip is conveyed from the die over horizontal rollers 27 which are spaced apart so that the strip may be festooned, as at 63, to allow for differences between the speeds of extruding the strip and of applying it to the tyre. A second, parallel row of rollers is positioned on which extruded strip, which is not to be applied directly to a tyre may be festooned and allowed to cool. The extrusion die head 36 is fitted on the end of a cylinder 35, Fig. 4, in which works the head 34 of the extrusion ram. The ram also comprises a hollow sleeve 33 inside which is a piston rod 44 and into which extends the cylinder 46 in which the piston 45, mounted on the rod 44, is reciprocable. The cylinder 45 is fixed to the end plate 47 of a larger cylinder 32, through the other end of which the sleeve 33 passes with suitable packing. The die head 36 may be swung open about a hinge 38 ; when closed it is held by a pivoted locking arm 39, Fig. 6. Milled rubber containing compounding ingredients and a vulcanizing agent is softened, by heating it in a steam or water heated chamber, and placed in the open cylinder 35, the extrusion ram being retracted. A choke is then inserted to ensure an even flow of material over the whole die area. The choke comprises two plates 52, 53 spaced by bars 54, 55 and shaped pieces 56, Fig. 8, and cut away at 58, 59, to provide flow channels for the rubber which is also deflected by bars 61 on the front face of the plate 53. Arcuate rim plates 57 are an easy fit in the extrusion cylinders 35. The extrusion cylinder 35 and die-carrying head 36 are jacketed at 48, 49 for steam or water heating. With the rubber charge inserted the die head is closed and locked by the arm 39 and hydraulic pressure is applied to the piston 45 to bring the extrusion ram rapidly into contact with the material, when the hydraulic pressure is diverted to the ram itself to effect the extrusion. The thickness of the extruded strip may be controlled by varying the hydraulic pressure on the ram, and a thickness indication may be associated with the die head. The choke may have alternative forms. The dies may be interchangeable.

Title: Improvements appertaining to apparatus for buttering and slicing bread
IPC: B26D7/34
Filed: 1932-10-07
Abstract: 407,749. Buttering and slicing bread. DRUM ENGINEERING CO., Ltd., and BEVER, A. J. M., Humboldt Street, Bradford, Yorkshire. Oct. 7, 1932, No. 27890. [Classes 28 (i) and 28 (ii).] The butter container of a machine for buttering and slicing bread is moved automatically, by the reciprocations of the bread carriage, away from the bread during the return stroke of the carriage, and then towards the bread to apply and spread the butter. The butter container 5 is mounted on guides 5b and is pressed towards the slicing plane by springs 9. A spring- returned pivoted member 7, carried by the carriage 6, bears during the return stroke, against an inclined cam 8 carried by the container 5 and ending in a step 8<a>. The container is thus forced away from the bread during the return stroke, until the member 7 falls over the step 8<a> when the springs 9 restore the container to the operative position. During the slicing stroke, the member 7 rocks against the effort of the spring 7b, and rides over the step 8<a>. The knife 23 is a straight stationary blade, the angle of incidence relatively to the bread being adjustable by a knob 23<a>. The carriage 6 may be reciprocated automatically, but as shown, is of the push-pull type. The pusher 6<f> has spikes 6d associated therewith and is actuated by slice feed mechanism comprising a sliding rack 11 which abuts, at each end of its stroke, against adjustable stops 11<a>, 11<w>, the rack gearing with a pinion 11<b> carrying a pawl 12 which engages a ratchet wheel 12<a> on the feed screw 6<a>. An adjustable guide 32 for the forward end of the loaf is provided and a spring- pressed roller 33 bears on the top of the loaf, the roller being raisable to an inoperative position by a handle 34b associated with locking- means. The butter feed is effected by a projecting pin 22 on the carriage 6 engaging, at times, with a slotted arm 21 which is thus rocked, and transmits its oscillations through the shaft 20 to a slotted link-work 19<a>, 20<a> associated with a ratchet mechanism 18, 18<a> actuating the screw 14 on which the pusher 13 is mounted. Adjustment and retraction of the pusher 13 is effected by a knob 60b and, when the butter feed is not to be operated, the pawl 18<a> is held away from the ratchet by a releasable spring-pressed member 60<a>. When it is desired to slice without buttering, the shaft 36<a> is turned by a handle 36 to rotate the cam 38 to the dotted line position, Fig. 4. The spring 20<w> then moves the arm 21 to the dotted position, i.e. out of the path of the pin 22. The connecting rod 38<a>, and link 39 simultaneously allow the swinging catch 40 to fall and lock the butter container, by engagement with the pin 50, in its inoperative backward position. The cut slices are guided by fixed guides 80, 80<w> and slide on to plates 81, 83 which are carried by spring-returned shafts 82, 83<a> in such manner that the plates yield under the weight of the slice and allow it to fall on the pile 80<y>.
