FEEDING DEVICE.

SPECIFICATION forming part of Letters Patent No. 761,040, dated May 24, 1904. Application filed May 19, 1903. Serial No. 157,830. (No model.)

To (all whom it may concern:

Be it known that we, WILLIAM FRANCIS, FRANcIs L. MORTON, and WILLIAM SPINK, citizens of the United States, all residing in the city and county of Philadelphia, State of Pennsylvania, haveinvented a new and useful Improvement in Feeding Devices, of which the following is a specification.

Our invention relates to a feeding device adapted to carry stock from a dolfer to a floorapron or elsewhere.

It consists of means for laying the stock in even folds and for regulating the laying device to suit the stock handled.

It further consists of novel details of construction, all as will be hereinafter set forth.

Figure 1 represents a top plan view of our device detached. Fig. 2 represents a vertical section through line a: m, Fig. 1, with a portion of the cooperating mechanism. Fig. 3 represents an end elevation of a portion of our device. Fig. 4 represents a detached portion of the device shown in Fig. 3. Fig. 5 represents a section through the line y 1 Fig. 2. Fig. 6 represents a detached end elevation of the roll portion of our device, Figs. 5 and 6 being on an enlarged scale, Fig.6showing a slight modification. Fig. 7 is a fragmentary vertical section through line 2 a, Fig. 1.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, 1 designates a doffer-roll from which a stripper 2 deposits the stock 3 n acarrying-apron 4. These are well known in the art and form per se no part of our invention. Mounted on a suitable stand is a shaft 6, which may berotated in any convenient manner, as through the pinion 7. On the shaft6 areeccentrics 8 8, radially slotted at 9 and secured by means of collars 10 and nuts 11, as is clearly shown in Fig. 5.

Straps 12 and connecting-rods 13 lead to a frame 14,reciprocahle on a stand 15 and running on casters 16.- Shafts 17 and 18 on the frame 14 carry rolls 19 and 20. At the end of the shafts 17 and 18 are connecting-pinions 21 and 22, beyond which on the shaft 18 is a sprocket-wheel 23. A chain 24 connects this with a driving-sprocket 25, cccentrically mounted on the shaft 6, as shown in Fig. 7, the tension of the chain being maintained by an adjustable idler 26. Slots 27 and 28 in the frame 14 permit an adjustment within the limits of the teeth of the pinions 21 and 22 of the distance between the rolls 19 and 20. A floor-apron 29 of usual or desired form is located beneath the rolls 19 and 20.

The operation is as follows: The rolls l9 and are interposed between the discharge end of the carrying-apron 4 and the floorapron 29. Between these rolls is carried the stock 3. It is evident that the reciprocation of the rolls 19 and 20 will act to lay the stock in even folds upon the floor-apron. The width of the folds is varied by changing the throw of the eccentrics 8 by engaging them with the shaft 6 at any desired points of the slots 9. The propersupport of the stock during its downward travel and its compression to the desired extent is secured by the rotation of the rolls 19 and 20 and the adjustment of the distance between them.

We have shown at the discharge end of the carrying-apron 4 a roll 4, over which the stock 3 passes to the rolls 17 and 18. We find in practice that the roll acts to take the stock 3 off the horizontal portion of the apron 4 completely and cleanly. When the stock is allowed to flow over the curved end of the apron in the usual manner, it has a greater tendency to adhere than where the roll is used.

It is evident that various changes may be made by those skilled in the art which may come within thescope of our invention, and we do not, therefore, desire to be limited in every instance to the exact construction herein shown and described.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

plane and means for reciprocating said rolls, the rolls being located in the path of the sheet of stock passing downward from said receiving means and operative to lay the stock in folds upon said carrying means.

2. A stock-feeding device comprising a doffer-roll, means for receiving the stock therefrom, a floor-apron, rolls intermediate said means and said apron and spaced away from said means, a track on which said rolls are guided, means for reciprocating said rolls and means for rotating the same, said rolls being located in the path of the sheet of stock passing downward from said receiving means and operative to lay the stock in folds upon said floor-apron.

3. A stock-feeding device comprising a doffer-roll, a carrying-apron adjacent said doiferroll and running in a substantially horizontal direction, a floor-apron, a pair of rolls intermediate said aprons and spaced away from both, means for maintaining said rolls in a substantially horizontal plane and means for reciprocating said rolls, said rolls being located in the path of a sheet of stock passing downward from said carrying-apron and operative to lay the stock in folds upon said floor-apron.

' 4. A stock-feeding device comprising a doffer-roll, a carrying-apron adjacent said dolferroll and running in a substantially horizontal direction, a floor-apron, a pair of rolls intermediate said aprons and spaced away from both, a track on which said rolls are guided in a substantially horizontal plane, means for reciprocating said rolls on said track and means for rotating said rolls in opposite directions, said rolls being located in the path of a sheet of stock passing downward from said carrying-apron and operative to lay the stock in folds upon said floor-apron.

5. A stock-feeding device comprising a doffer-roll, a carrying-apron adjacent said dofierroll, a floor-apron, a pair of rolls intermediate said aprons and spaced away from said carrying-apron, means for maintaining said rolls in a substantially horizontal plane and means for reciprocating said rolls, said rolls being located in the path of the sheet of stock passing downward from said carrying-apron and operative to lay the stock in folds upon said floor-apron.

6. A stock-feeding device comprisinga doffer-roll, a carrying-apron adjacent said dofl'erroll, a floor-apron, a pair of rolls intermediate said aprons and spaced away from said carrying-apron, a track on which said rolls are guided in a substantially horizontal plane, means for reciprocating said rolls on said track and means for rotating said rolls in opposite directions, said rolls being located in the path of the sheet of stock passing downward from said carrying-apron and operative to lay the stock in folds upon said floor-apron.

7. A stock-feeding device comprising a dotfer-roll, a carrying-apron adjacent said doflerroll, a floor-apron, a pair of rolls intermediate said aprons and spaced away from said carrying-apron, a track on which said rolls are guided in a substantially horizontal plane, an eccentric by which said rolls are reciprocated, and an eccentrically-mounted drivingpulley operative to rotate said rolls in opposite directions, said rolls being located in the path of the sheet of stock passing downward from said carrying-apron and operative to lay the stock in folds upon said floor-apron.
