Title: Materials handling pallets adapted for use as accessories in fork lift truck operations
IPC: B65D19/00
Filed: 1945-11-22
Abstract: 608,874. Pallets for handling loads. CAHNERS, N. L. Nov. 22, 1945, No. 31487. Convention date, May 14, 1943. [Class 78 (iv)] A pallet for handling loads comprises a base with a platform supported above and parallel to the base by spacing members which are located at the corners of the base and intermediate of the corners so as to provide on at least two adjacent sides of the pallet two openings for the forks of a lifting truck. In the embodiment shown in Fig. 1, the pallet comprises a base 4 and platform 2, each formed from a sheet of plywood and secured together by spacing blocks 6 and a central block 8 so as to form openings such as 10, 12, 14, 16 for the lifting forks 20, 22. The blocks are preferably formed with bevelled edges. To enable the pallet to be used with trucks providing only a low lift in which the forks are provided at their ends with pivoted wheels which are lowered so as to raise the end portions of the forks a small-amount, the base is formed with openings 30a, 30b, 30c, 30d for the passage of the wheels. To facilitate handling of the pallet by slings, the blocks 6 may be spaced inwardly from the edges of the base as in Fig. 2 to allow the insertion of rods along the opposite edges of the pallets, said rods having sling ropes attached to their ends. Fig. 3 shows a modification in which the base and platform are built up of spaced planks.

Drawings to Specification. [Class 98 (i)] In a focal-plane shutter having a pair of curtains movable relatively to one another to form an exposure slit, and then moving together to make the exposure, on operation of the release member the second curtain is held by a latch on a pivoted lever until the first has moved to establish a slit between them of a width corresponding to the setting of a speed-selector member made by a manually-operated cam, the latch being then tripped to release the second curtain by means of a floating lever pivoted between its ends to a pivoted lever which is moved by a cam rotating with the first curtain and which moves the floating lever until one end bears against the adjusted speed-selector member, whereupon the other end trips the latch and thus releases the second curtain at the moment when the first has moved to form a slit of the width pre-determined by the setting of the speed-selector member. The invention is described in connection with the focal plane shutter described in the abridgment of Specification 520,957, the manual speed-controlling means illustrated in Fig. 13 (cancelled) being employed.
