Abstract: 201,734. Salter & Co., Ltd., G., and Bache, E. W. July 10, 1922. Delivery of articles stored in piles; coin action, mechanical-connection; storage.-Relates to coinfreed delivery apparatus for towels &c. wherein the towels are separated by plates with opposite projections resting on lugs on controlling slides which are moved to allow a bottom plate to fall and deliver the towel through a chute. On inserting a coin and operating a rock shaft by an ex. ternal handle, an arm on the shaft first acts through the coin and then directly to move one of the slides and the other slide is simultaneously moved to release the bottom plate and towel of a pile. Means are provided which necessitate full movement of the slide before it can return, and also to prevent insertion of a coin when the pile is exhausted or after partial movement of the operating handle. The projections of the bottom plate of the pile of plates and towels rest in lugs 10, Figs. 2 and 6, on controlling slides mounted by pin-and-slot 14, 13 inside a, casing with a lockup front 3 having a coin aperture 5 opposite a coin shoot 24 which directs the coin to a recess 22 in one slide 9. The coin is supported by a fixed pin 25 until on actuation of an externally-operated rock shaft 17 an arm 21 thereon acting through the coin 23 displaces the slide 9 sufficiently for the coin to fall into a receptacle 26 after which the end of the arm 21 acts on the slide to complete its movement and thus displace the lugs 10 to release the bottom plate and towel, the next plate then descending on to lugs 11. The opposite slide is connected with the rock shaft by link or other mechanism to release simultaneously a towel support, and on the return movement of the slides, under spring action, the lugs 11 pass from below the pile of plates and towels which descend on to the lugs 10. When the arm 21 is moved in the absence of a coin, a notch 44 in the arm engages the edge of the coin slot in the slide 9, which is not therefore operated. The plates 6 are notched to fall past inclined arms 27 which direct the towel &c. to a delivery shoot 28 leading to an aperture 4 in the casing front 3. To prevent return of the slide 9 before completion of its movement, an eccentric-shaped pivoted pawl 37 engages a part 38 on the slide and is only released and tilted out of action into engagement with a spring plate, 42 by means of a lug 40 when the slide completes its movement, another lug 41 placing it in operative position again on return of the slide. Coin-slit closing-devices.-Insertion of a coin into the chute 24 is prevented when the pile is exhausted by the entry into the chute of bent wires 45 pivoted in lugs 46 and extending into contact with the 'bottom plate 6 of the pile which holds them against spring or weight action clear of the chute. A coin is also prevented from passing down the chute to the slot in the slide 9 after the rock shaft 17 and arm 21 have moved by additional spring or weight actuated pivoted wires which are bent so as normally to be held clear of the chute by resting on the arm, but which penetrate the chute when the arm is moved.
