Filed: 1937-09-07
Abstract: 501,921. Ambulance stretchers. JACKSON, E. W. Sept. 7, 1937, No. 24443. [Class 108(i)] In an ambulance stretcher comprising longitudinal side bars 2 connected by collapsable traverse bars 1 or toggle levers which are provided with means operative automatically for retaining the bars against collapse on completion of the opening movement of the stretcher, the retaining means is constructed as a gravity catch so that it may be released by inverting the stretcher. As shown, the adjacent inner ends of each pair of bars 1 are pivoted to a block 3 having a downward projection 3b, a rod 5 being secured to one projection and being slidable in the other projection which contains a recess housing a ball 8 adapted to drop into a recess 9 in the rod when the stretcher is fully extended. The ball is released to permit collapse of the stretcher when the latter is inverted. The legs 4 of the stretcher each consists of two, coaxial parts connected by a stud which constitutes the pivot for the outer, end of the corresponding bar 1. The invention may be applied to existing stretchers by forming the blocks with pivot projections adapted to replace the usual hinge pins connecting the traverse bars. In a modification the rod 5 is replaced by a telescopic member one part of which carries the ball or other looking element and the other part the recess for receiving same. In another construction (not shown) the ball or the like may be embodied in one part of the toggle-lever device and arranged to co-operate with a recess in the other part.

Abstract: 979,536. Shovelling equipment. GENERAL MOTORS CORPORATION. June 20, 1963 [July 10, 1962], No. 24538/63. Heading E1F. The length of a fluid-actuated jack 44, such as provided for tilting the shovel of a shovel excavator, is indicated by an associated mechanism comprising a cam 50, a cam follower 64, a pointer 72, and an index. The cam is rigidly secured to the cylinder 53 of the jack 44 whilst the cam follower 64, preferably integral with the pointer 72, is pivotally mounted at 48 on the piston rod 58 of the jack. The movement of the cam follower over the cam resultant to actuation of the jack causes the pointer to swing past the index rigidly mounted on the jack. An alternative form of a cam and follower to the one shown is also described. The cam is a rod extending from the piston rod end of the cylinder parallel to the rod, whilst the follower is formed of a pair of spaced triangular plates between which the piston rod is accommodated. One pair of vertices of the plates form the pointer, whilst a plate is transversely secured between the plates adjacent another pair of vertices with the inner end of the plate spaced from the piston rod so that the inner edge of the plate, which serves as a cam follower, can run along the cam rod and one side of the plate can slide over the end of said rod.

Abstract: 806,283. Locks. YALE & TOWNE MANUFACTURING CO. Aug. 17, 1956 [Aug. 26, 1955], No. 24547/55. Class 44 A lock comprises, a body part 10, a keyoperated bolt 14 slidable within the body and having a longitudinal slot 15 in which a slide 16 is mounted, a member 21 slidable at right angles to the bolt and adapted to move the slide, one or more blocking pieces 24 slidable at right angles to the bolt and having notches 25 to be engaged by a projection 22 on the slide during movement of the bolt. As described, the slide 16 has a longitudinal slot 17 engaged by a fixed pin 18, and a lateral pin 19 which engages an oblique slot 20 in the member 21. This member and one or more blocking pieces 24 are slidably mounted upon fixed pins 18, 23, and have cam edges 27, 26 which are engaged by a key 13. When withdrawing the bolt, the key first engages the edges 26, sliding the blocking pieces upwards so that the lower notch 25 of each piece is in line with the projection 22. Further clockwise rotation of the key causes the member 21 to slide upwards and thereby move the slide 16 so that the projection 22 engages the lower notches 25. The key then acts directly on the bolt to withdraw it, after which the member 21 and the blocking pieces 24 return to their former positions. Upper notches, 25 formed in the blocking pieces are aligned with the projection 22 when a master-key is used. The bolt may be dead-locked by engagement of a projection 30 formed on the member 21 by one of two slots 31 formed in the lower edge of the slot 15. In another embodiment, Figs. 4-6 (not shown), the projection 30 and the slots 31 are omitted, the member 21 is shaped to avoid engagement by the key, and a pin on the member 21 engages an inverted V-shaped surface or slot in the bolt 14. Movement of the bolt raises the member 21 and thereby causes the projection 22 to engage the notches 25. In a further embodiment, Figs. 7-9 (not shown), the slot 20 in the member 21 is so shaped that the slide 16 moves oppositely from its motion in the previous embodiments. The projection 22 passes through a slot in the member 21 and through a smaller slot in each of the blocking pieces 24; and teeth on the projection 22 engage similar teeth on one edge of each of the smaller slots to prevent picking.
