(Crm1-88) My invention relates to delivery mechanism platform stands substantially at thellevel of the for printing' presses, and has Wfor its'object 'the top face ofthe conveyer belt 12. The arrangeprovision of a new and improved form and arment lfurther is such that, upon delivery of a rangement of parts by which the folded products signature or other folde'd'productv into position in the form of complete papers `or pamphlets or upon the platform, the' platform is adapted to in the form of signatures or other parts of aV4 descend slightly against the Vaction of thesprings magazine orL book may be stacked evenly in a VS0 alito bring the t0n faee Of SuCh folded Product pile for convenient handling. .Itis another object 'substantially to the level of the top face of the of my invention to provide an'improved arrangedeliverybelt. As a result of this arrangement,`

Collars 19 are pro- Upon the link 33 I have mounted a coil spring vvidedv on the upper ends of the rods 16 'serving V34, one end of which bears against a collar g to limit the upward'movementwof the platform.` 35 carriedby the link 33 and the vother vend of The-arrangement is such that when the platfor'iri which i bears against a bracket 36 Y rising from 17 is not provided with a load the'top face of the the base 10. The arrangement is such that the 110 spring r34 normally holds the arm 30 in the position as shown in solid lines in Fig. 2, in which position the arm serves to stop the outward movement of successively delivered signatures. When upon the continued operation of the press and the delivery belt 12 a pile of signatures or other folded products have accumulated upon the platform 17 in neatly piled superposed po-V sition thereon, an operator is able to grasp such pile by the outer corners thereof and withdraw the same very readily and quickly toward the left in said Figs. 1 and 2., the arm 30 being adapted to yield readily vagainst the 'action of the spring 34 into the position as shown in dotted lines in Fig. 2 for permittingsuch, removal of the papers. The springs 18 thereupon bring the platform 17 again to its elevated position ready to receive the next successive signature from the delivery belt. At the same time the spring 34 serves to vbring the arm 30 again toA normal position as shown in solid lines. o

" For providing additional assurance thatI the papers will be kept in evenly piledk arrangement on the platform, I have provided means yfor jostling 'the' papers slightly as they are deliv-l ered. In the construction illustrated, this jostling effect is brought about through the medium ofjthe arm l which is given a limited swinging movement toward and from the platform. The 30 "ward the `platform 17 when it is released after spring 34 serves to provide .the movement toa movement away from the platform. The means for effecting movement of thearm away from` the Iplatform against the action of the spring .34'comprises a yoke lever 37 mounted upon a "rock shaft 38. The shaft `38 is actuated by means of a lever 39 mounted on said shaft, with'its free end connected to an upwardly extending link 40. The upper end of the link 40 is en- ,gaged during a portion of the rotation of the "sprocket gear 1 5 by a pin`41 extending outwardly from said gear; such pin 4l serving totforce the link 40 downwardly. This movement of the link serves to rock the shaft 38, causing the .,lever 37 to swing toward the right in Fig.2,

'serving by engagement with a pin 42 carried by the link 33 to move the link v33 `toward the right in said figure so as to swing the arm 30 toward'the left. When the pin 41 inthe rotation of the gear 15 reaches the lower part of its 'movementit passes out of engagement with the upper end of thetlink 40, whereupon the spring 34 is free to lmove the arm 30 again toward the right into engagement with the face of the pile `of signatures upon the platform 17 so as to deliver a light blow upon any V paper extending Yslightly beyond the face of the pile. This intermittent jostling movement of the arm 30 serves to keep etheedges of the signatures in evened --position with respect to each other. AWhile I prefer to employ the construction substantially as shown in the drawing and as above described, it is to be understood that my invention is not limited thereto except so far as the claims may be so limited by the prior art, it being vunderstood that' changes may well 'be made in the construction without departing from my invention.
