Abstract: 159,006. Karck, G. S., and Varndell, S. H. Nov. 17, 1919. Delivery and hiring of towels etc.; coin action, mechanical-connection.-Apparatus for delivering towels and other articles and comprising shelves one above another adapted for release successively from the lowest upwards by the angular movement of a vertical member operated through coinfreed mechanism is constructed with the releasing-mechanism for each shelf as a self-contained unit consisting of a plate carrying a pivoted shelfsupporting lever, a spring-pressed trip lever normally holding up the supporting-lever and carrying a pivoted controlling-arm, and a sliding striker, the arm being automatically positioned for actuation by the striker by the operation of the unit immediately below. Provision is made for ensuring a full movement of the operating- lever, for closing the coin shoot when all the shelves have been released, for returning the released shelves to normal position, and for securing the towels to the apparatus. Superposed shelves are pivoted at c<1>, c<2>, Fig. 1<a>, in a frame a and supported by separate release mechanisms each comprising a plate e<2> carrying a lever f<2> pivoted on the axis of the shelf pivot and engaging the shelf frame by a pin h<2> Fig. 4. a pivoted spring-controlled lever o<2> normally supporting the lever f<2>, and a longitudinal slider k<2> with pin m<2> and foot n<2> from which an arm q<2> pivoted on the lever o<2> is normally held disengaged by a finger r<2> on the arm resting on the supporting-lever f<2> of the unit below. The lowest shelf-releasing mechanism differs from the others in that there is no finger and the arm q<1> is normally engaged with the slider k<1>. The sliders are moved longitudinally simultaneously, thereby rocking the lever o<1> to release the lever f<1> so that the lowest shelf falls and the arm q<2> of the mechanism above engages with its slider ready for release at the next operation and so on, by the engagement of their pins m<2> by a channelled extension w of a rock-shaft v actuated by a link 32, Fig. 7, from a pivoted bell-crank lever 31 oscillated by a spring-controlled pivoted arm 23 on a slide plate 9 carried by an operating-bar 5 with a handle 6. A coin 21 inserted through a shoot 47 falls through a slot 10, Fig. 6, in the plate 9 and rests on an inclined groove 19 in a spring-supported lever 13 pivoted to a bracket 2 supporting the plate, and a pivoted stop 15 on the lever projects through the bracket to prevent a complete movement of the plate. by means of the bar except when a coin is present, in which case the plate acts on the coin to depress the lever 13 and withdraw the stop 15 so that the bar can be drawn forward fully by the handle 6 to operate the release mechanism for the lowest supported shelf. A rack 7 on the bar and a pawl 8 on the bracket necessitate a complete movement of the bar before it can be returned, and a press pin 22 is provided for releasing the slide when the mechanism is out of order. When the top shelf is released, a vertical rod 41, Fig. 1<a>, supported thereby falls and rocks a counterweighted bellcrank lever 44 so that its end 45 is projected across the coin shoot 47. The towel falls from a released shelf into the curved bottom 53, and the towels may be secured to the apparatus by chains passing through an eyelet in the towel and terminating in rings sliding on a rod 48 extending across the bottom and up one side of the frame. All the fallen shelves are lifted collectively by a bell-crank lever acting through a rock lever to reciprocate a rack 33, Fig. 1<a>, gearing with quadrants 34<1>, 34<2> which carry lugs engaging under the shelf-supporting levers f<1>, f<2>. The frame is enclosed in a casing provided with apertures for the handle 6, coin insertion and towel outlet.
