Application mea December 16,1902. serial No. 135,363.

Be it known that I, CHARLES E. SAGE, a citizen of the United States, residing at Jersey City, county of Hudson, and 'State of New Jersey, have invented certain new and useful lmprovementsin Sheet Separatingand Feeding Mechanism, fully described and represented in the following lspecification and the accompanying drawings, forming a part of he same.

This invention relates to machines for feeding sheets successively from a pile and for associating sheets as they are advanced successively from a plurality of sources, and the invention aims generally to improve such machines and to provide mechanisms for accomplishing these results which shall be rapid and sure in'operation.

A full understanding of the invention can best be given by a detailed description of a preferred construction embodying the various features of the invention, and such adescription will now be given in connection with the' accompanying drawings, showing such a'preferred construction. I

ln said drawings, Figure 1 is an end elev'ation of a' sheet separating and associating machine constructed in accordance with the invention. Fig. Q is a front side view thereof. Fig. is a rear View thereof. Fig.A 4 is a sectional detail view taken on the linel4 of Fig. 1. Figs. 5 and 6 'are sectional detail views taken on thelines 5 and 6, respectively, of Fig. 2. Fig. 7 is a plan View of two sheets as associated by the machine', and Fig. 8 is a front elevation of-the magazine and feeding devices shown in Fig. 4.

'lhis invention has been made with the idea of providing a machine for feeding small sheets, such as coupons, from a pile and for associating such sheets or coupons with larger sheets. such as wrapper-sheets. Any suitable mechanism may be provided for advancing the wrapper-sheets separately, but they are preferably, and as shown, advanced successively from the pile by sheet separating and feeding mechanism such as is described in my application, Serial No. 80,789, liled No- I vember 1, 1901.

sheets of the pile in position to be engaged by the separatingand transferring devices. The sheets are removed singly from the pile by means of a suction-transferring device, comp`rising a suction-cup 35, carried' by an arm 36, which is pivotally connected to a supporting-lever 37, actuated by a cam-disk 39 f on a-shaft 41 to raise and lower .the suctioncup. The arm 36 is also given a forward and rearward swinging movement by means of an eccentric 42 on the shaft 41, acting through a pitman 43, pivoted to the arm 36 and con- 6 nected to the eccentric-strap. The suctioncup is connected with a vacuum apparatus, vand communication between the suction-cup and the vacuum apparatus is controlled by a valve 46, which is operated to establish communication between the suction-cup .and

vacuum apparatus, and to close such communication and open communication between the suction-cup and atmosphere at proper times to cause the suction-cup to seize and release the sheets. This sheet-separating mechanism also includes an auxiliary suctiorrcup', connected with the vacuum apparatus by a passage controlled by a suitably-operated valve, and which auxiliary suction-cup 8 acts to raise the edge of thesheet slightly before the sheet is seized by the suction-cup 35. The sheets are deposited by the suction-transferrer 35 upon the table or Way 150, alongv which they are advanced by means of fingers 151 on endless chains152. These parts are or may be as shown and described in my application above referred to and for fuller description of such parts reference is made to said application.-

Mounted above the IWay is a magazine or holder 300, adapted to receive a pile of sheets b and from which the bottom sheets are fed successivelythrough an opening beneath the front wall of the holder by means of a feeder 301, mounted in position tocoact with the bottom edge of "the front Wall of the -holder to cause but a single sheet to be aderabl y formed by a vertically-adjustable plate Y 302, and the inner face of the lower portion of the front wall of the holder is preferably inclined outward, as by means of an outward bend of the plate 302.

The feeder 301 is preferably a rotary feeder ing one or more slightly-projecting segmental feedingfaces 303 of a circumferential length less than the length of the sheets to be fed. If' formed of a roll o f a size to provide sufficient space between the feeding-segments, the feeder may be continuously driven,

as shown. Forcompleting the feeding of the sheets from the holder drawing- rolls 304 and 305 are preferably vprovided mounted in position to receive between them the edge of the sheet which has been advanced by the feeder 301. These rolls are preferably geared to rotate together, and one of said rolls is preferably spring-mounted, as shown. The rotary feeder will thus act to advance the sheet from the holder far ehough to enter its forward edge between the rolls 304 and 305 and will then release the sheet and permit it to be entirely withdrawn by the rolls 304 and 305. By having the rotary feeder release the sheet after its forward edge has been advanced by the feeding-rolls the feeding of but a single sheet at' a time betweenthe feeding-rolls is insured, since even if the-edge of the second sheet should be drawn between the bottom sheet and the lower edge of the plate 302 there will be no further forward movement vof the second sheet when the feeding-segment of 'the rotary feeder has passed the edge of the plate 302; but it will remain stationary until the feeder again begins to coact with the plate 302'for ad vancng the next sheet in time tothe feeding-rolls.

In order to insure an accurate'timing of the sheets, .the feeding-rolls 304305 are preferably driven intermittently, having a movementiong enough to insure the feeding between the rolls of a sheet and then resting until the edge of the next sheet has been entered between them. To move the bottom sheets toward the plate 302 and insure the forward edge of the bottomsheet entering between the plate 302 and the feeding-segments 303,`a feeding-roll 306 ris preferably provided in the bottom 'ofthe holder.

Any suitable connections may be employed for driving rolls 301,` 304, 305, and 306, as described. As shown, the shaft of the roll 301 carries a sprocket-wheel 307 and is driven by`means of a sprocket-chain 308 from a sprocket-wheel on a main driving-shaft 309, and the rolls 304 305 are driven intermittently by meansyof a mutilated gear 310 on the shaft of the roll 301, adapted to engage a pinion 311 on the shaft of the roll 304 and to give the rolls 304 305 two movements for each rotationfof the roll 301 and to rotate them at each' movement a distance at least sufficient lto feed a sheet between them. To insure the stopping of the rolls 304 305 `after each feedspaces -with a greater surface-speed than the feedingroll 301. The feeding-roll 306 is drivenvby a pinion on the shaft 301 through an intermediatev meshing with a pinion 314 on the shaft of the roll 306.

The sheets may be received from the rolls 304 30.5 by any suitable conveying, or othermechanism. In the machine shown the sheets fed from the rolls 304 305 drop onto a way 320, along which'they are advanced by feeding-iingers'321 on a chain 322, the feedingfingers being spaced. and the chain driven at such a speed that the rear edges of successive sheets dropped onto the way will be engaged by the feeding-fingers and the sheets advanced along the way.

For associating the sheets fed from the holder 300 with sheets fed from the holder 10 the way 320 is preferably provided with a downwardly-inclined `extension 323, which forms an inclined way into which the sheets are advanced by the-feeding-fingers 321 and l from which they drop onto sheets ,being advanced `in the way 150. If the sheets b were allowed to simply slide down the inclined` way 323 and onto the'sheets a in the way 150, they would have considerable momentum and be apt to slide along too far on the sheets in the way 150. To prevent this, a stop 324is.

provided at or near the lower extremityA of the inclined way 323 in position to arrest the movement of the sheets near the end of the way alud which after arresting a sheetis with-` drawn. to permit the sheet to slide from the inclined way-onto the sheet in the way 150. The sheets will thus fall onto the way 150 with but little momentum, and there will be but slight, if any, sliding of the sheets on the Vsheets in the way 150.

The stop 324 may be operated by any suitable means; but, as shown, it is carried by a lever 330, which is operated by means of a cam 331 on the shaft of one of the sprocketwheels 332, about which the chain 322 turns, said cam acting through a connecting-rod 333, one end of which is pivotally connected to an arm of the lever 330 andthe other end of which is suitably guided in position to bear against the face of the ca'm 331 and held in contact therewith by means of a spring 334.

An opening 335 is preferably provided in' the way 150 at the point where the sheets from the inclined way fall. A plate 336 is preferably provided to guide into-a suitable receptacle the sheets 7;, which will fall through the and to which the foregoing description hasv opening if no sheet a is over the opening when the sheet b falls to the way 150.r

In order to prevent backward movement of the devices for feeding the sheets b from theA tion with said shaft by lmeans of a one-wayoperating clutch 340. This clutch may be of any suitable form; but as shown a shouldered collar is provided fast on the shaft and engaged by the shouldered face of the hub of the sprocket-wheel, the sprocket-wheel hub being held in engagement with the fast collar by a spring 341, and the shouldered'collar and face of the hub being formed witliinelined faces, so that if the sproket-vsheel is moved backward its hub will be mowed away from the fast collar against the tension of the spring 341, and no movement will be given to the shaft. l

The feed-chain 322 may be driven in any suitable manner. As shown, it is driven from theshaft of the` roll 301 by means of a sprocketchain 342, running over sprocket-wheels on the shaftof the roll 301 and on -the shaft of one of the sprocket-wheels 332, by which the chain 322 is carried.

.It is to be understood that the invention is not limited to the exact arrangement or construction of parts as shown in the drawings for the purpose of illustrating the invention mainly been/confined, but that various changes and modifications thereof may be made within the claims. It will be understood also that A parts of the invention may beemployed independently of other parts thereof and in combinationwith other coacting parts.
