Abstract: 1,098,164. Cutting webs. PAPER CONVERTING MACHINE CO. Inc. June 17, 1965 [July 21, 1964], No. 25600/65. Heading B4B. Apparatus for cutting a stack of continuous superposed webs, e.g. stacks of facial tissues, towelling &c., comprises a frame 10, a first conveyer 11 to support and advance the stack, a disc blade 14 mounted for movement through the stack and a second upper conveyer 12 to compress the stack. As described, the lower conveyer comprises crossbars 13 spaced to permit entry between them of cutting discs 14, and is driven by sprockets 15, 16 and a shaft 20, Fig. 2 via gearing 21, 22. Similarly the upper conveyer 12 is driven in synchronism via sprockets 23, 24, a shaft 25, Fig. 2, and gearing 26 interconnected with the gearing 22. The upper conveyer carries U-shaped members 29 which coact with the crossbars 13 to compress the web during its entire travel through the frame. Cutting discs 14 are secured to a shaft 30 and driven via a pulley 31 by a motor 33. The frame 10 includes a shaft 34 rocked by a linkage 36, Fig. 2, and interconnected with the shaft 30 by arms 37 each carrying sharpening rolls 39 for the discs. By swinging a lever 40 controlled by a link 43, longitudinal movement of the rocker shaft is effected, so that the discs move downwardly and forwardly in achieving a out. Retraction of the discs includes an initial forward movement for their withdrawal from between adjacent U-shaped members 29a. This movement is effected by a follower roller 40a on the lever 40 engaging a rotating eccentric cam 45. A second cam 46 rotatable with the cam 45 imparts via a link 44 and roller 44a a rocking movement to the shaft 34 and blades 14 into and out of cutting position. In operation, the spacing between the U-shaped members may be changed by relocating them along the chain of the conveyer, by moving the bars of the lower conveyer and changing the spacing between the cutting discs 14.

Abstract: 888,339. Moulding refractory bricks. DETRICK CO., M. H. July 29, 1959 [March 30, 1959], No. 25984/59. Class 87(2). Refractory bricks having metal plates disposed therein are made by releasably supporting the metal plates within the interior of a brick mould cavity prior to the filling of the mould with a refractory material in such a way that the plates are completely surrounded by the material, releasing the plates after the filling of the mould has been completed, and compressing the material in the mould cavity to final brick size. The mould 23 has two plungers 24 between which the plates 21 are held by a plate holder 22 comprising a frame member 26, to which is rigidly attached a handle 27. A first plate holding comb 28 is rigidly attached to the handle 27 and the frame 26 and is provided with slots 29 for receiving the plates 21. Second plate holding combs 31 are provided and are attached to the distal end of lever means 32 rotatably attached to the frame 26 by a pivot 33. Spring means 34 between the handle 27 and the lever means 32 tend to hold the combs 31 in a vertical position, thus co-operating with the fixed comb 28 to grip the plates 21. On operation of the lever means 32 after the mould has been filled, the combs 31 are rotated against the action of the spring means 34 to release the plates 21 and the plate holder 22 is then removed prior to the operation of plungers 24 to compress and mould the brick. In a second but preferred embodiment, Fig. 15, combs 41 depend from frames 40 of U-shaped cross-section so as to form fingers 43 between which are pivotally suspended fingers 44 and cam members 47 suspended through the frames 40 by shafts 48. Levers 51 are connected to the shafts 48 so that the cam members 47 can be rotated to cause plates 21 to be gripped between fingers 43, 44 and members 47 in one position and to release them on further rotation. In a further embodiment, Fig. 12, handles 52 are rigidly attached to plate holding combs 53 and are connected to an electromagnet 54 which, upon energisation, causes the comb fingers to become magnetised and hence hold the plates 21 in position until it is deenergised. The plates 21 may also be held in position by utilising vacuum means connected to the fingers of combs 53 so as to hold the plates 21 across their vertical faces.
