Abstract: 1,033,739. Hydraulic reciprocating motors. KEELAVITE HYDRAULICS Ltd. June 18, 1963 [June 19, 1962; Dec. 3, 1962], No. 23584/62 and 45665/62. Heading F1A. An hydraulic motor, e.g. for a percussive tool, comprises a double-acting, working piston 4 in a cylinder 1 forming working chambers 8 and 9 of different effective cross-sectional area, chamber 8 of smaller cross-sectional area being in communication with an hydraulic accumulator 1 1a connected via a check valve 24 to a source of working liquid pressure, e.g. pump 21, and chamber 9 of larger cross-sectional area being connected alternately to the source of working pressure and to a relief passage 25 by a control valve 17 hydraulically controlled by piston 4. From the position shown, piston 4 moves  rightward until port 29 is exposed to the pressure in chamber 9 and ports 30 and 31 are interconnected, thereby connecting the left-hand end of valve 17 to pressure and its right-hand end to exhaust, to effect reversal. During rightward movement of piston 4, the liquid on the righthand side is forced into accumulator 11a and raises its pressure above the pump delivery pressure. On reversal of valve 17, working chamber 9 is connected to exhaust and piston 4 is moved leftward by the pressure in accumulator 11a, until port 30 is exposed to pressure and ports 29 and 31 interconnected, to effect another reversal of the valve. Holding pistons and cylinders 33, 35 and 34, 36 in valve 17 act to hold the valve in position at each end of its movement. Check valve 24 allows limited leakage to discharge accumulator 11a when the motor is not in use. An accumulator 26a and a relief valve 21a are incorporated in the pump delivery circuit. In another embodiment, accumulator 26a is omitted and relief valve 21a located adjacent the motor. In the embodiment of Fig. 4, (not shown) the working chamber of smaller cross-sectional area is defined by a chamber 46 in the working piston and a projecting portion 47 of the cylinder.

Title: Web severing and sheet delivering mechanism
IPC: B65H35/08
Filed: 1938-08-11
Abstract: 521,141. Sheet-delivery apparatus; cutting- apparatus. HOE & CO., Ltd., R. (Hoe & Co., Inc., R.). Aug. 11, 1938, No. 23760. [Class 100 (i)] In an apparatus for cutting printed &c. webs into sheets and delivering the same, the cutting- cylinder is fitted with suction-operated means which is flush with the cylinder as it holds the leading edge and is subsequently moved radially outwards to permit the leading edge of the sheets to be taken by the grippers of a delivery device This device is preferably arranged to be gradually accelerated as it moves to co-operation with the suction device and to be retarded as it moves to the delivery zone. The web 11 is fed between the cutting-cylinders 22, 23 by pressing rollers 27, 35 engaging the cylinder 23, these rollers being carried by levers 28, 36 actuated by a cam 33 on the shaft of the cylinder, to press the rollers against the cylinder to maintain the web taut during the cutting operation. Arms 43 pivoted to the cylinder 23 at 45 are pressed by springs 49 against a fixed cam 48 so that their outer surfaces 53 which are adjacent to the cutter 25, normally lie flush with the surface of the cylinder 23. Suction openings are provided in the surfaces 53 and communicate by passages 56, 57, 58 and a valve 59 with a suction pipe 61. The valve 59 is pivoted to a lever 66 -actuated from cams 79 on the slowly driven shaft 72 of sprocket-wheels 73 for delivery chains 74, so that suction is applied to grip the leading edge of the web and is released when the edge is adjacent to the grippers 51, 52 on the chains 74. At the moment of release, the cam 33 causes the arms 43 to move outwardly. The delivery grippers each comprise a member 51, Fig. 6, fixed to a tube 94 and a coacting member 52 fixed to another tube 96 rotatable within the tube 94. A spring 102 normally holds the gripper closed, but an arm 97 fixed to the tube 96 carries a roller 98 which is engaged by cams such as 99 to open the grippers when adjacent to the sheetreceiving station and the delivery pile 26. As the grippers pass around the sprocket-wheels 73 their speed increases to that of the web because of their greater distance from the shaft 72 compared with the chain 74, and . subsequently decreases again. In order that such speed variations should be gradual, the tube 94, is mounted in brackets 81 so that it lies outside the pitch line of the chains 74. One end 82 of each bracket is pivoted to a pin 84 situated midway between the pivots of one of the chain links, and the other end is pivoted to an arm 87 itself pivoted to a pin 88 also situated midway between the pivots of one of the chain links. The arrangement is such that the speed of the gripper starts to increase when the pin 88 reaches the sprocket and reaches its maximum when the pin 84 reaches the sprocket. In a similar manner, the gripper speed is caused to decrease gradually

Abstract: 151,820. Anderson, F. A. B. Sept. 26, 1919. Holders for hand cutting.-A holder for meat &c. while being carved has a vertically adjustable support below the meat and two or more laterallyacting clamps. As shown in Fig. 1, a lateral clamp 4 adjustable by a screw 6 towards a fixed clamping-member 3 co-operates with a support 7 adjusted vertically by a hand-wheel 9 and longitudinally along a slot 11. In a modification, both lateral clamps are adjustable. Pins co-operating with rows of holes, or springs engaging ratchet teeth may be substituted for the screws 6. As shown in Fig. 9, the vertically adjustable support 26 rests on one end of a lever 27 actuated by a thumb-screw 28<a>. Two lateral clamps 18 are pivoted to the free ends of arms 30, the distance apart of which is adjusted by a thumb-screw 33, In the form shown in Fig. 11, three clamps 18 engage eccentric ribs 35a on a plate 35 which may be turned by a projecting handle to adjust all three clamps simultaneously. The support 26 is vertically adjusted by co-operating inclined teeth 38<a>, 39a, the lower set of which are turned to raise or lower the support bv a handle 38<b>. In a modification, Fig. 13, the clamps 18 are pivoted to ratchets 43 each pressed by a spring 44 against the edge of the casing 42 supported on a screwthread 41b of opposite sense to a screw-thread 41<a> carrying the support 26. As the screw-threads 41<a>, 41<b> are of opposite sense, e.g. right and left respectively, relative rotation of the casing and support lowers the clamps while raising the support or vice versa. The meat holder may be of wood, metal, china or earthenware, and may have clips or similar means for securing it to an ordinary meat dish.

Filed: 1935-08-30
Abstract: A machine for impregnating cartons or like articles with wax or the like, comprises a carrier rotating upon a vertical axis and fitted with a plurality of dipping-devices to which the cartons are fed successively, each article being dipped into a tank containing wax, withdrawn and inverted for draining, and then stripped from the dipping-device.  Such a machine is shown in the drawings, and comprises a rotatable carrier 2 for the dipping-devices, a carton feeding mechanism 3, and a rotary table 4 to which the cartons are delivered after dipping.  A belt conveyer 5 brings the cartons to the feed mechanism, and a second conveyer 6 receives them from the table 4.  Carton-feeding mechanism.--The carton-feeding mechanism comprises a wheel 56 having arms 61 provided with fingers 62 which can pass through open slots 63 in a tubular guide 64, and a cam-operated striker arm 76 and plate 78 which push the foremost carton x, laterally of the belt 5, so that it is lifted by a finger 62.  An electromagnetic control device may be provided to ensure that the cartons are struck singly by the plate 78.  On reaching the slotted cradle 100, the carton is pushed into a holder 42 by means of a cam-operated lever 98.  Another cam then raises the lever 98 so that its return movement takes place over the top of the cradle 100. Dipping-mechanism.--The rotatable carrier 2, 14 is provided with radially-disposed dipping-devices, each comprising a tubular pivoted arm 16 provided with a crank arm 18 actuated by a cam-operated slider bar 20.  A second cam-operated slider bar 30 actuates a push rod 36 connected to the bell-crank lever 40, 41 carrying a basket-like carton holder 42.  A part-annular waxing tank 47 is mounted concentrically with the pillar 8, on coupled screw jacks 48, 49, for vertical adjustment, and the circle around the carrier top 14 is completed by two part-circular draining trays <PICT:0463475/III/1> <PICT:0463475/III/2> 52, 53, which may be heated.  As the carrier 2, which may be driven intermittently, is rotated, each carton is first lowered into the waxing tank 47, is then raised so that it passes over the draining trays in vertical and inverted position, and is finally lowered into an approximately horizontal position to be removed from its holder 42.  This removal is effected by a lever 107 operated by a cam 106 on the main shaft 7, the ejected carton falling through a shoot 111 and arriving upon a rotating heated perforated table 4, by which it is led to a conveyer belt 6, and thence to a cooling chamber, storage room or filling machine.
