These Another object of the invention is to prochains carry a plurality of cross bars 8, duce such av construction which will be of these cross bars carrying belts or tapes 9, simple form and eflicient in operation and these belts or tapes being divided into pockwhioh may be employed without complicatets by fingers 10 carried by the beltsand bars, these pockets being capacitated to receive the desired number of products.

In accordance with the lnvcntion, mechanism is provided for pressing down or fiattening the folded back not as it is delivered from the folding cylinder into the pocket and, in the best constructions, these means 'will also act to assist in the positioning of the products 1n the pocket. While various devices may be employed for this purpose, in the particular construction illustrated, there is provided a plurality of stripper fingers 12, which act to strip the folded product from the fold ng cylinder 3, these stripper fingers bemg formed with curved ends 13 which are arranged to set into grooves let formed in the cylinder Wall. To afford a simple construction, these stripper fingers, are utilized for effecting the flattening or pressing down of the folded backs of the books. The fingers are, therefore, mountedto have a swlnging movement from the cylinder to the bottom of the pocket, the fingers being arranged to move between the pocket fingers 9 of the delivery carrier. WVhile various mechan sm may be employed for effecting this pressing movement of the fingers, in the particular construction illustrated, the fingers are car lied on a rock shaft 15 supported in brackets 16 in the side frames, before referred to. This shaft, at one end, has fast thereon a lever 17 to the ,arm of which is secured one end of a forked rod 18, the forked end 19 of this red taking over a driven shaft 20 suitably-journaled in the side frames 1, 1, before referred to. Fast on the shaft 20 is an operating cam 21 and the forked rod.

' 18 has secured thereto a cam roll 22 which "the stripper fingers runs on the cam 21 on the shaft 20. Also fast on the shaft 15, preferably at the end opposite the lever 17, is a lever 23 to one arm of which is secured a spring rod construction 24, this spring rod acting to keep the cam roll in operative position on the cam and to keep the stripper fingers 12 in the raised position shown in Fig. 1.

Located adjacent to the stripper fingers 12 is a plurality of stop fingers 25. these stop fingers being carried on a cross shaft 26 supported in the frames of the machine, before referred to, these.stop fingers preferf ably having curved ends 27 and assisting 12 in positioning the folded products in the pockets of the car rier. With this construction, as the cam roll 22 rides on the high part of the cam 21, through the rod 18 and lever 17, the shaft 15 is positively rocked and the stripper-fingers 12' given a quick downward slapping move ment which efiects a flattening or pressing down of the folded products which have been deposited in' the pocket, the parts being timed so that these stripper fingers are given their pressing movement as each prodor edge of each prodnot is stripped off by them and deposited in the pocket. The stripper fingers are, as shown in Fig. 2, of a sufficient lengtlrso as to bear a substantial distance inward from the folded edge of the product when they are in pressing position, as shown in Fig. 2, so as to effect a good flattening or pressing of the folded back of the product. These fingers, furthermore, act in conjunction with the guide fingers 25 to position the products in orderly piles in the pockets. It will be seen that with this construction a very simple and effective mechanism is provided for flattening the products and one which, as shown and described, adds but aminimum amount of mechanism to the delivery. This is particularly advantageous where two deliveries are'arranged close together.

Any suitable means may be employed for effecting an intermittent movement of the delivery carrier. In the particular construction illu'strat'ed the .driven shaft 20 is provided at one end with a gear 28 which meshes with a gear 29 supported on a hub 30 mounted in the side frame 1, before referred to. This gear has secured thereto one end of 'a link 31, the other end of this link being secured to one arm of a lever 32 journaled on a hub 33 ofa gear 34 mounted on a stud 35 suitably supported in the side frame 1,'before referred to: On the hub 33, adjacent the lever 32, is secured a ratchet Wheel 36 and adjacent the ratchet 36 1s a second slightly larger ratchet 37, this ratchet being loosely mounted on the stud 35. The operating teeth of the ratchet 37 are cut so that the bottom of the teeth are above the outside periphery of the ratchet 36. One or more of the teeth, as'for instance as shown at 38, of the ratchet 37, are

cut deeper than the others, the bottom ofv shown in Fig. 1. Co-operating with the ratchets is an operating pawl 39 pivotally mounted on the lever '32 and normally pressed into operating position by a spring 40, The operating face of the pawl is. as wide as both ratchet 36 and 37'and will pass over ratchet 36 except when it drops into the deep teeth 38 of ratchet 37, in which case, the. pawl will engage the ratchet 36 and thus operate to rotate the gear 34 and cause the carrier to advance a pocket length. The shaft 20 may be driven in any suitable manner, as by a gear 11 on the end of the shaft opposite the gear 2-8, before referred described in what is believed to be its best without departing from the invention as defined in the claims hereunto annexed.

What I claim is:

1. In a delivery, the combination with means for forwarding folded products, a traveling carrier provided with pile supports to which the products are delivered flatwise in piles, meansfor giving the carrier a horizontal movement away from the forwarding means, and means for pressing or flattening the folded backs of certain products on their fold lines after the products have been delivered on a pile, said pressing means acting on the same pile a number'of times durin the completion of the pile.

2. n a delivery, the combination with means for forwarding folded products, a traveling carrier provided with pile Supports on which the products are delivered in piles, means for effecting an intermittent fi movement of the carrier, and means for flattening or pressing down the folded backs of certain products on their fold lines after the products have been delivered 011 a pile, said pressing means acting on the same pile a number of times during the completion of the pile.

3.
