Filed: 1953-10-26
Abstract: 763,610. Forging. TURNER BROS. (BIRMINGHAM), Ltd. Oct. 25, 1954 [Oct. 26, 1953], No. 29468/53. Class 83 (4). Mechanism for feeding blanks into a press comprises a slide 17 having a blank receiving pocket 20, movable from an outer position where it receives a blank from a supply station to an inner position adjacent the press die 51 and an ejector 23 mounted on the slide for ejecting the blank into the die. The mechanism is particularly adapted for a press having a tool 49 moving in a horizontal or inclined direction, and the feed slide 17 reciprocates in horizontal guide-ways 13 disposed transversely of the axis of the main tool. The blanks fall down a shoot 22, Fig. 3 (not shown) to the feed slide. The latter is actuated from the main press ram 47 through a rocking lever 36, pivoted at 37 to a yoke 38 pivoted on a stationary pin 39, drag links 35, links 32, triangular plates 28 mounted on a stationary pivot 29, and driving links 26 connected at 25 to the slide. The ejector 23 is actuated by a lever 24 mounted on the pivot 25 and connected by links 33 with the links 32. The latter are biased by a strong spring 43 passing through a hole in a spacing block 44 disposed between the triangular plates and connected to the latter at 46. During the retraction of the ram 47 the slide 17 moves inwardly until it engages a stop 52 whereupon the pivotal movement of the triangular plates 28 is arrested and the links 32 stretch the spring 43 and move the links 33 to actuate the lever 24 and hence the ejector 23. A block 40 adjustable along the rocking lever 36 enables the stroke of the slide 17 to be varied.

In a free-piston motor having compression chambers 16, 17 and working chambers 20, 21 arranged independently, a device, such as a rotary valve 22 mounted in the piston 11, for controlling the inlet and outlet for the working fluid is driven by an unbalanced member 27 which is rotatably mounted at right-angles to the axis of the piston and driven by the acceleration forces thereof in such a manner that for each complete oscillation of the piston a complete revolution-of the member 27 occurs, the rotary movement of the latter being initiated by a starting device which is disconnected automatically after a predetermined speed of rotation is reached. The member 27 is mounted on the valve spindle 26 and is provided with a passage 39 which leads from the valve interior tangentially outwards and through which compressed-air escapes for rotating the member at starting. A centrifugally controlled device in the interior of the member 27 closes the passage 39 at a given speed. At starting, compressed-air enters annular grooves 28, 29 in the cylinder 10 and passes through passages 31, 32, valve 22 and bore 34 to the chamber 21 so as to move the piston in the direction of arrow 42, the chamber 20 being exhausted through bore 33, valve 22 and outlet groove 30.

[Class 80 (ii)] [See also Group XVI] In a hectograph - copying machine, a gelatine band is operated from a main shaft 11, Figs. 23 and 26, driven in either direction and at a variable speed according to the position of a control lever 55. The shaft 11 is rotated from a rotary shaft 10 by an epicyclic gear train, the direction and speed of rotation being controlled by fluid pressure. Each of two pairs of gear wheels 30, 31 and 37, 39 forms a pump adapted to suck lubricating oil from a tank 63 through pipes 60, 61, and to discharge it through outlets 48, 49, into a gear casing 15 draining back into the tank through a pipe 71, a baffle 64<a> directing the returning oil to a point remote from the suction point so that the circulation is maintained. The gear 30 is fixed to a sleeve 27 loose on the shaft 11 and integral with a sun wheel 73 having twenty one teeth, the gear 37 is fixed to a sleeve 38 integral with a sun wheel 85 having twenty-seven teeth, and a sun wheel 90 of twenty-four teeth is keyed to the shaft 11. Each of three sets of corresponding planet gears 74, 86, 92, is fixed to a sleeve mounted on a spindle 76, the three spindles being carried by a housing 79 fixed to the shaft 10. A valve 50 is rotatable to open and close the outlets 48, 49, so as to vary the retarding effect on the pumps and therefore on the sun gears 73, 85. When both outlets are fully open, there is equal effect on both gears, and the planets 92 roll on the sun 90, the shaft 11 being stationary. When the port 48 is closed and the port 49 is open, the sun 73 is at rest, and the shaft 11 is rotated in the same direction as the shaft 10 but at a reduced speed. When the port 49 is closed, the direction of rotation is reversed. In intermediate positions, one port is closed and the other is partly open so that intermediate speed values in either direction are obtained. A byepass 290 is connected through a relief valve 291 to the delivery side of the pump 38, 39, to prevent over-tensioning of the gelatine band.
