Title: Improvements in or relating to retaining-ring assembly tools
IPC: B25B27/20
Filed: 1960-06-01
Abstract: 882,040. Tools for assembling split rings on shafts. WALDES KOHINOOR Inc. June 1, 1960 [June 2, 1959; Aug. 21, 1959], No. 19379/60. Class 61. A tool for assembling external, split, retaining rings on grooved shafts comprises a pair of pivoted arms one of which carries a head adapted to spread a ring to be assembled having an unstressed inner edge diameter less than that of the shaft to an internal diameter corresponding to that of the shaft, responsively to axial movement of the ring along the head, the other arm carrying a ring pushing head adapted to exert push on the face of the ring and spread the ring. As shown in Fig. 1, the arm 12 carrying the frusto-conical head 24 is pivoted at 20 to the handle 16, the arm 14 which carries the semicylindrical pusher forks 30a, 30b being fixed to the handle by rivets 18. A leaf spring 22 urges the arms into open position. The top upper corner of the head 24 is chamfered to facilitate positioning of the ring R. The ring R may be positioned by hand on the head 24 or the tool may be inverted and pushed into the opening of an untensioned ring. The head 24 is connected to the arm 12 by a blade-like neck 28 which enters the gap between the open ends of the ring to be assembled. The larger diameter end face of the head 24 is recessed to receive the end of the shaft on which the ring is to be assembled. The tool is held up against the end of the shaft and the arms are closed, final closing movement causing removal of the ring from the spreader head and on to the shaft. In a modification the arm carrying the spreader head is fixed to the handle, the spreader arm being pivoted to the fixed arm either externally or internally of the handle. In another modification, Fig. 13, the ring push head is comprised by arcuate bifurcations 68 on an arm 61. To enable the tool to pick up a ring to be assembled a strap-form member 70 of flexible material, having one end secured flush against the upper surface of the arm 61, terminates at its free end in a downwardly depending blade-like end 72 adapted when pressed into the ring opening to frictionally grip the ring along diametrically opposed points of its inner edge. The end face of the spreading head 66 on the arm 60 is longitudinally slotted to receive the lower edge of the blade 72. In another modification Figs. 17-23 (not shown) the spreader head is of rectangular plate or bar-like form.

[Class 7 (ii)] A suction on the exhaust gases is produced by arranging a slotted aerofoil, or a series of aerofoils adjacent the junction of an exhaust pipe and a collector into which it opens. Fig. 5 shows, in section, half a collector, divided on the line X, which is connected by passages 12a, 12b, 12c to pipes leading to the different cylinders of a multicylinder engine. Slotted aerofoils 13a, 13b, 13c, shown in detail in Fig. 6, are arranged adjacent the outlets of these passages which are flared, as at 20. The flow of gas through the slots produces a zone 25a-26a of negative pressure, indicated also at 23, Fig. 5, which tends to draw out the exhaust gas. In a radial-cylinder engine slotted aerofoils, at the junctions of pipes from individual cylinders to an annular collector, cause the exhaust gas to circulate round the latter. In a further modification a series of small aerofoils are arranged to overlap, intermediate narrow slots producing the effect described above ; the aerofoils are located at the junction of flat pipes with a collector. Specifications 430,134,.446,131 ; 456,063, [Group XXXIII], and 478,576, are referred to. The Specification as open to inspection under , Sect. 91 describes also exhaust silencers comprising stacks of hollow annular washers, inside which the exhaust gas rotates before it emerges through narrow spaces between the washers. The co-operation of these spaces and curved surfaces produces on ejector action on the exhaust gas. Further exhaust details are the same as described in Specifications 478,576 and 482,085. This subject-matter does not appear in the Specification as accepted.

Abstract: 574,564. Refrigerating. STEVENS, A. H. (Gibson Electric Refrigerator Corporation). Dec. 1, 1943, No. 20079. [Class 29] [Also in Group XXIX] Absorption systems. In a system in which a continuously heated generator 10 is replenished intermittently with strong liquor from an absorber vessel 25, transfer of the liquor through a vessel 36 is controlled by a valve device 37 comprising a ported piston valve 49, Fig. 2, actuated by a thermal element 4 6 in the generator and movable from a fully open position, in which a high pressure vapour conduit 43 connects with a conduit 42, leading to the top of the transfer vessel and a liquor conduit 41 from the bottom of the transfer vessel connects with a conduit 44 leading to the generator, to a fully closed position in which all connections are blocked. Vapour rising through an analyser column 13 above the generator passes through a rectifier 17 and down to an air cooled condenser 19, and the condensate is raised by the vapour pressure to a receiver 21 fitted with a float valve controlling flow to the evaporator 22. Vapour flows from the evaporator through a pipe 31 leading into the riser limb 30 of a liquor-cooling circuit including a pipe 26 from the absorber vessel, a jacket 27 around the transfer vessel, a pipe 28 and air-cooled coil 29 and the return pipe 30. Absorption takes place in the pipe 30 and some liquor is delivered therefrom by open branches 30a into a vessel 38 connected by a conduit 39 to a check valve 40 to the bottom of the transfer vessel. The weak liquor flows through a conduit 34 and float valve 32 to the absorption vessel, and a restricted flow is provided through a passage 53 to the transfer vessel. When the valve piston 49 is raised by the action of the thermal element condenser pressure is established in conduit 42 and the transfer vessel to deliver the contents of the vessel through conduit 44 and a jacket 45 of the thermal element to the analyser column. The cooling of the thermal element is rapid and the valve is reversed. The restricted flow of liquor into the transfer vessel causes absorption of residual vapour and reduction of pressure below that of the absorber vessel, and the check valve opens to admit fresh liquor until the vessel fills and a back pressure closes the check valve. A float 52 in the transfer vessel separates the vapour and liquid to reduce absorption.
