` .To a/ZZ whom it may concern:

Beit known that I, CONSTANT T. OUNDALL, a citizen of the'Uiiited States, and a resident of Ashaway, in the county of Washington 5y and State of Rhode Island, have invented a s new and useful Improvementin Sheet-Delivery Apparatus ,forl Printing and Folding Machinery, of which i the following is a specification. I p 1o The principal object of this invention is to facilitate the transfer of-` folded sheets .from a folding mechanism, which may be an ad# junct to a printingm`achine, to a carrier, by which the sheets are delivered in piles or fin a train; and to this end the improvement con! i sists in part of a sheet-dropper of the novel construction 'hereinafter described and incertain combinations hereinafter described and claimed, in which the said dropper con- The invention is illustrated in the accom- I panying drawings, in which- A,

asectional view corresponding with parts of Fig. 5, but illustrating a carrier on which the 4o`sheets are collected from the dropper in a train. i

` Referring first to Figs. 1, 2, and 5, the fold'- ing mechanism, which is therein 4represented and which serves as well as any other for the 45, illustration of my invention ,consists of a folding-cylinder 10, furnished with two sets of gripping-jaws 11 and a tuking-cylinder 12,` furnished with a tucking-blade 13, coperating alternately with one andthe other set Serial No. 158,313. (No model.)

of gripping-jaws to fold sheets presented `to said cylinders in any suitable manner. The

shafts 45 46 of said cylinders run in fixed bearings on the side framing 9 and are geared together by gears 47 48, so that the tuckingpieces 15 15, carried by one of a series of Vpairs of shafts `19, which are irmly-secured in the chains 14 and the ends of which are furnished, as shown in Fig. 6, with rollers 20, running in the horizontal guides 18. .The wheels 16, which are sprocketwheels engaging with the chains 14, are carried by the shaft 21, which is the driving-shaft of the carrier and which runs in fixed bearings in or on the side framing 9. The wheels 17, which are merely supporting-wheels, run loosely on xed studs 22 in the horizontal frames 23, of which the guides 18 form part and which are supported in part by the transverse framing .24 and in part by standards 25, erected on the bed-plate 26.

The dropper 27 2S,which constitutes the principal feature of the present invention and which is for receiving the foldedsheets or signatures from the folding-cylinder and depositing them in the carrier-pockets 15, is

shown in Figs. 1, 5, 6, and 8l arranged some two similar members 27, each consisting of a longitudinal projection of cruciform oru winged transverse section from one'end of one of two horizontal shafts 28,which are arranged parallel with each other and with the length of the pocketed carrier and transversely to the axes of the cylinders 10 12 in bearings 29j in the transverse framing. The space between said members 27 and the relative arrangement of said shafts 28 and the pocketed carrier and cylinders is such that two opposite margins of a folded sheet or signature 3l may, as shown in Fig. 6,be supported upon two of the wings 32,-that is to say, upon one wing 32 of each member-Which are prescnted horizontally with the corresponding edges of the sheet or signature betwee'n two others of said wings, which are at the same time presented upward. The dropper-shafts 28 are geared together in such manner, as will be hereinafter described, that they rotate together in opposite directions, each in such diing the said members downward and outward removes the support from the sheet, which then drops into one of the pockets 15, which is at the time stationary under the dropper. To provide for the transfer of the sheets or signatures from the folding-cylinder 10 to the dropper, there is represented a carrier consisting of two sels of tapes 33 34. (See Fig. 5.,) The tapes 33 run in'grooves in the cylinder and around wheels 35, running loosely on a shaft 36 and being kept at proper tension by idler-wheels 37 in swinging arms 38. The tapes 34 run on wheels 39 40 4l, the wheels 39 being fast on a shaft 42, running in bearings in theside framing 9, the wheels 40 being loose on a fixed shaft 43 and the wheels 41, which are tightening-Wheels, being hung in swinging arms 44. The tapes 33 are driven by the cylinder l0 and those 34 through the gearing of their shaft 42 by a gear 46* with the gear 48 on the cylinder 10.

The relative movements of the several parts ofthe machine illustrated by Figs. l'to 8, inclusive are as follows: The tucking and folding" cylinders 12 10 have continuous rotary motion, and the carrier 33 34 has a continuous movement.l The intermittent rotary movements of the dropper are so timed that they take place quickly once for every folding operation. The movement ofthe pocketed carrier takes place only after every such number of sheets or signatures 31 as are desired in avpile have .been deposited in a pocket 15, which has been stationary under the dropper.

' The means for imparting these movements to the several parts, which all derive their movements from the shaft 46 of the foldingcylinder 10, will now be described.

For driving the dropper there is provided onone end of said shaft 46 a bevel-gear 49. This bevel-gear` gears with a bevel-gear 50 on av shaft 51, Figs. 1 and 2, which runs in bearings in brackets 5,2 on the outside of the framing 9 and which carries another bevel-gear 53, which gears with a bevel-gear 54 lon a shaft 55, Figs. 1, 2, 5, 8, and 8i", which is ar ranged crosswise of the pocketed carrier and of the dropper-shafts 28 in bearings in brackets 56 on the cross-framing 24. The said shaft 55 carries two ruiter-gears 57, which gearwith two miter-gears 57* on short shafts 58, arranged parallel with the dropper-shafts 27 in bearings in the cross-framing 24. The said shafts 58, which receive a constant rotary motion at the rate of one revolution for every half-revolution of the folding-cylinderl 10 and every delivery of a folded sheet, are each furnished with a disk 58, (see Fig. 7,) which carries an eccentric-pin 59, which engages with radial slots 60 in disks 61 on the dropper-shafts 28, the said slots in each disk corresponding in number with the wings of the droppers, so that a quarter-revolution of the dropper-shafts and one operation of the dropper is produced by each revolution of the shafts 58.

The means represented in Figs. 1, 3, 4, 4*, 5 for giving motion to the pocketed carrier are such as are now well known, having been described in United States Letters Patent No. 604,004, dated May 10, 1898, and therefore need here only to be briefly described. They derive their movementsfrom a cam 62, Figs. 1 and 3, on a shaft 64, which is arranged parallel with the folding and tucking cylinders in bearings in the side frames l9 and which is geared with the folding-cylinder 10to make two revolutions for every one of the said cyl-- inder by means of a spur-gear on the shaft of said cylinder, a spur-gear 66 on said shaft 64, and an intermediate spurl-gear 67, running onafixed stud 68,carried by the side framing 9. This cam 62 acts at the proper time against a roller 69 on a lever 70, which works on a fixed fulcrum 71 in a stand 71*, the upper end of said lever having connected with it a toothed rack 72,which engages with and turns a pinion 73, which is loose on the driving-shaft 2l of the carrier, but which is engaged with said shaft by means of a pawl 74 and ratchet-wheel 75, (see Fig. 4*,) the said-ratchet-wheel being fast on the shaft and said pawl being carried by an arm 75*,attached to the said pinion. This engagement only takes place when turning in the direction of the arrow shown near it in Figs. 1 and 3, this direction being the the lever is held out of the operative rangeV of the continuously-rotating cam 62 by means of a detent 76, which is pivoted by a pivot 76* to the stand 7l* and which is engaged by a stud 77 on the said lever; but at the `proper time for moving the carrier the said detent is lifted from the stud, and Vthe lever .is brought within the operative rangeof the 4cam by means of a spring 78, which always IIO presses it toward the cam.

stand 7l* and which acts against a toe 8l,

`attached to the detent. `The operation of i this trip-lever 79 is produced and controlled by intermeshing gears 82,83 and tappets S4 85, thereto attached. The gear 82, which is carried by the cam-shaft 64, has-a less number of teeth than `that 83, which turns on a fixed stud 86 on the stand 7l* and is driven by that 82.` The tappet 8l on the gear 82 is fixed upon said gear; but the tappets 85 on the gear 83 are attached to slide radially on said gear under the control of springs which tend to press them outward. Once during a y given number of revolutions of the two gears and at a time when the inner end of one of the sliding tappets 85 is opposite the lower end of the trip-lever 79 the tappet4 84 comes against the outer end of said sliding tappet and presses the said tappet inward against the trip-lev`er,`.which then presses upward the toe 8l of the detent,`and so raises the latter from the stud 79 of the lever 70 and allows `the said lever to be brought by the spring 78 within range of the cam 62, which then during a portion of its next revolutionproduces the necessary movement of said lever and its rack 72 to produce the operation of the car- `rier. .While the detent is inoperative it is supported by afixed stop 92 on the side of the stand 7l*, as shown in Fig. et.A The number of sheets or signatures deposited in a pile in the pockets between the movements of the carrier will depend Aon the relative numbers of teeth in the gears 82 83 and the numberof tappets on said gears. If, for example, there are fortyfseven teeth -in gear 82 and forty? eight teeth ingear 83 and there are two tappets on the gear 83 and one on that 82, the

carrier will be moved once for every twentyfour sheets or signatures deposited.

In the modification of my invention illustratedin Fig. 8* the continuously-moving carrier, on which the sheets or signatures are deposited by the dropper, consists of an endless apron or series of tapes 87, carried by wheels or rollers 88 89, carried by shafts 90 91, to which continuous rotary motion may be given by any suitable means. The sheets or signatures deposited on the so-moving carrier lie thereon in a train in which each sheet or signature 31 partlyoverlaps its predecessor, as

shown in said figure.
