Title: Improvements in or relating to sheet delivery mechanism applicable for use in connection with printing and other machines
IPC: B65H29/68
Filed: 1940-05-17
Abstract: 537,909. Sheet-delivery apparatus. TIMSON, E. A. May 17, 1940, No. 8827. Addition to 477,620. [Class 100 (i)] In a sheet delivery mechanism as in the parent Specification in which sheets while being deposited are controlled by suction nozzles which engage the rear ends of the sheet and move forwards with the sheet, then downwards and finally slightly rearwards before releasing the sheet, the suction nozzles 1 are mounted on a carrier A formed of bars 3 connected by a bar 4 and mounted adjustably in carrier bars 2 having spaced blocks 2a supported by a pair of swinging levers 5 which are operated by cams to give a swinging to-and-fro motion to the nozzles. The nozzles 1 are also given a swinging up-and-down movement by means of oscillating levers 8, which carry a spindle 7 on which the nozzles are mounted and which are connected to parallel links 12. The levers 8 are mounted on the bars 3 and are operated by a lever-andlink connection 18, 19, 20 with a slotted bar or link 14 carried by a pair of parallel levers 15, 16 connected by a link and operated from a cam 24 by a lever 27 and a link 29. A knocking-up device 30 may be mounted in the carrier and it moves with the suction nozzles 1, and partakes of the adjustment movements of the bars 3 which may be effected by a rack 3a and pinion 31 operated by a hand-wheel. The lowering of the delivery table is controlled by feelers 35 mounted on the carrier A and acting upon a catch 51 which normally restrains the motion of a masking device 40, and so keeps the mask in a position in which it renders the action of a pawl ineffective to operate the table-lowering ratchet. When the pile needs lowering the catch 51 is rendered inoperative and the mask then moves to such a position that the pawl 36 can operate. Specification 325,906, [Class 100 (i)], also is referred to.

Title: Improvements in or relating to devices for controlling or regulating air supplies
IPC: F23D11/04
Filed: 1934-03-23
Abstract: 425,262. Valves. BURROUGHES, S. H., Dean House, Dean Street, Oxford Street, London. March 23, 1934, No. 9183. [Class 135] [See also Groups XXVI and XI] A current of air created by a fan 32 is controlled by a valve 8 operatively connected to a differential pressure device 9, the arrangement being such that air is not discharged normally from the fan until a predetermined time has elapsed from the start of the fan. A cylinder 7, attached to, or integral with, the fan casing 28 has a gunmetal piston forming the valve 8. The differential pressure device has a flexible diaphragm 9 clamped between the two parts 11, 12 of the casting ; the centre of the diaphragm is held between two metal discs 20 secured to the tube 15 which forms the stem of the valve 8. The position of the valve 8 can be adjusted and fixed, on the tube by means of lock nuts, and its upward movement is limited by the screw 3. Openings 24, 23 in the casing above and below the diaphragm respectively are controlled by adjustable screws 1, 2. In the form shown the fan is applied to an oil burner having a nozzle 29 to which fuel is supplied by the valve 30 and the tapering passage 31 which is rotated by the fan driving motor 27. When the motor is started and the valve 30 is opened, oil is thrown out from the tube 31 and can be ignited electrically. During this initial period the valve 8 is closed and the fan draws air from above the diaphragm 9 through the tube 15, and some of it passes through the passage 23 to the space below the diaphragm. Eventually the diaphragm rises as a result of the difference of pressure created and this raises the valve 8 thereby opening the inlet for the fan to operate normally, and the valve is maintained in its open position. Air is then blown to the nozzle 29 to produce the normal flame indicated by the dotted lines 34. The time required for the lifting of the valve 8 may be varied by adjusting the screws 1, 2.
