Filed: 1937-04-29
Abstract: 477,137. Jigging-couveyers. BRAUN, W. April 29, 1937, No. 12285. [Class 78 (i)] [Also in Group XXVI] Driving means for a jigging shoot comprises a compressed air motor b arranged at one side of the shoot a, and a compressed air cylinder f having a piston which also drives the shoot, arranged at the other side, the air cylinder, which is not provided with a controlling valve, being in communication with the cylinder of the compressed air motor by means of a detachable connecting pipe i so that the compressed air is also admitted thereto. The piston rods d, d<1> of the cylinders b, f, are connected to a yoke k on the shoot. The controlling device of the cylinder b is moved in one direction by the action of the piston rod d on a cam e, and is returned by compressed air as soon as the piston g has moved beyond the pipe h. During the movement of the pistons to the right the air in front of them escapes through apertures (not shown) in the ends of the cylinders. The singleacting motor b can be replaced by a double acting motor, in which case the cylinder f is connected to it by two pipes. In a modification the pipe i is arranged at a small distance from the ends of the cylinders so that the pistons travel over it, and it does not act to reduce the compression. A second pipe of small cross-section connects the cylinders and serves to equalize the pressure in them. This pipe may also be used to admit an initial quantity of compressed air to behind the piston of the auxiliary cylinder when the pistons come to rest near the ends of the cylinders.

Abstract: 777,002. Ball joints. EHRENREICH & CIE., A. April 28, 1955 [May 21, 1954], No. 12294/55. Class 65 (2). A ball joint of the kind in which a ball stud enters a socket with a cylindrical inner surface and has a coinpressed lining of deformable material round its middle zone is assembled by inserting the lining in the form of a cylinder (which may be formed by a wound strip of material) and then compressing it into close contact with the ball. In the forms shown in Fig. 2, the lining 3 rests on a shoulder at the lower end of a sleeve 4 and after insertion of the ball 1 the upper edge of the sleeve is turned over to compress and retain the lining. In these forms an additional lining 9, which may extend around the neck of the ball stud as at 10, is provided between the sleeve 4 and the socket 5. The parts of the joint are secured by a cover 7 or a screwed cap 8, whether or not the lining 9 is provided; in a modification the lining 3 may be compressed by a spring placed between the cover and an annular plate resting on the lining, the upper edge of the sleeve 4 not being turned over. In a further form, Fig. 8 (not shown), the lining has an internal diameter smaller than the size of the ball, which is forced into'it after it has been placed directly in the socket, the sleeve 4 being omitted; a disc of rubber-elastic synthetic resin, which may be perforated and may have radial slits, is pressed against the top of the ball by a spring under the cover, and a flanged collar of similar material fits round the ball stud with its flange between the lining and the socket. Spaces may be provided for flow of the lining in compression, such as apertures 12 in the lining 9 in Fig. 2, or a notch or groove in the lining 3, or apertures in the sleeve 4. The lining 3 may be formed by wrapping a strip of material round the ball, the strip having notched edges to facilitate its compression round the ball, but is preferably cut from a length of tube; it may comprise two layers of different material and thickness, for example to provide a more suitable bearing surface for the ball of a rubber-elastic synthetic resin of the group of poly-addition products with a cross-linked structure, while the outer layer may be of rubber or some other more or less elastic synthetic resin.

Abstract: 415,983. Valve generating circuits. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. April 24, 1934, No. 12334. Convention date, April 25, 1933. [Class 40 (v).] Intermittent current impulses are generated from an alternating-current source 11 by the use of a discontinuous-control triode valve 12 connected in series with the source 11 and with a resistance 13. A positive half-cycle of current passes through the valve, and charges up a condenser 14 by virtue of the voltage developed across the resistance 13. The negative side of this condenser is connected to the grid of the valve which prevents the passage of further current. The condenser gradually discharges through an adjustable resistance 15, and after a determined number of cycles of the source 11 the valve is again conductive. Intermittent current impulses are thus passed through the load resistance 10.

Abstract: 654,442. Signature gatherers; feeding sheets. HOLMEN, K. May 5, 1948, No. 12347. [Class 100 (i)] Signatures or sheets are gathered from a number of piles arranged in parallel rows by transferring one sheet from the first pile in each row to a collecting path associated with the row and moving it step-by-step along the path to positions where it is associated with sheets successively removed from each of the remaining piles in the row, the groups thus formed (one from each row) being collected in a similar step-bystep manner to form a complete set in correct sequence. Fig. 4 shows an arrangement wherein sheets from each of piles A<SP>1</SP>, A<SP>2</SP>, A3, B<SP>1</SP>, B<SP>2</SP>, B<SP>3</SP> are simultaneously transferred by grippers 7 to two collecting paths 6, and are then pushed one step to the right by pins 15 on conveyer chains 16; at the right-hand end the groups of sheets from each path 6 are received by cages 19 on a vertical conveyer E which moves down one step simultaneously with the transfer of the sheets from the piles to the paths 6; before this movement of the conveyer E the complete group of sheets from the lower cage 19, Fig. 7, is transferred by an ejector 21 to a delivery table 20. The piles of sheets are placed, folded edge downwards, on inclined tables 2, Fig. 1, each having a weighted prop slab 4 which presses the sheets towards a front stop 3 and rods 14; conveyer belts may replace the tables 2. The grippers 7 comprise suction cups slung by blade springs 8 from a common horizontal pipe 9 and connected thereto by rubber hose 10; during transfer of the sheets to the paths 6 the pipe 9 is connected through valves to a source of suction and is rotated in bearings on arms 12 pivoted at 13. The collecting paths 6 have a front edge 6a and a back wall 6b extended into baffles 18 (see also Fig. 4). The ejector consists of ribs 23, Fig. 4, which move through openings 24 in the cages 19; blade-springs (not shown) hold the sheets on the delivery table 20. Collecting paths 6 may be arranged to feed right- and lefthandedly into cages on a common vertical conveyer E.
