' 10 rain peculiarities, of the construction, noyel arrangement and combination of the parts thereof as will be. hereinafter more fully set forth and specifically claimed.

The principal object of my invention is, to

provide a very simple and, eificient attachment to be usedin connection with bread wrapping machines, for the purpose of more effectually preventing backwlashing. or buckling of the paper inits operation,- of being fed from. rollers under a knife. or cutter, by means of which it may be severed into proper lengths of sheets, which are afterwards used for wrapping loaves. of; bread.

Another object of the invention is, toprovide means whereby the position of thepaper. holding finger or fingers may, be adjusted to the most effectual position with respect to one of the rollers over which the, paper is fed before it; is cut.

Another object of the invention is, to furnish a pap r Stop. of great, durability, and which shall be automatic in its operation and shall consist of but few parts.

Other objects and advantages of the invention will be' disclosed in the following description and explanation, which will be more readily understood when read in conjunction with the accompanying dra-wlng, in which, an embodiment of the invention is illustrated, it being understood that changes and modifications may be resorted to without a departure from the spir t of the invention, so long as they fall within the scope of the appended claim.

In the drawing V Fig. 1, is a top view of a portion of a bread wrapping machine showing my invention mounted thereon and in its operative position.

Fig. 2, is a view in side elevatlon of a portion of a table or platform of the machine over. the top of which the paper is fed to a knife or cutter and held by my improvements for intermittent movement and.

Fig. 3, is a, detached perspective View of the paper holding stop and its bearing members detached from, the platform or table.

Corresponding numerals of reference refer to like parts throughout the different views of the drawing.

In the accompanying drawing, it will be understood, that I have shown only such parts of a bread wrapping machine with which my improvements are associated, the other parts, of said machine being omitted for the sake of clearness and because their illustration in the present instance would be useless.

A part of the horizontal portion of the 7 table on the, top, of which the paper is fed along in the customary manner, is designated by the reference numeral 5, while the legs or upright portion of one end thereof, is designated by the numeral 6, and may extend entirely across the platform 5, but is usually in the, form of legs at each corner of the platform or t ble. This upright portion 6. is provided at its upper end at each side of the ilatform, 5, with a horizontally disposed brac et 7, which are spaced apart, as shown, and have j ournaled thereon between the same a roller v8, over which the paper 9, passes from the feed roller 10, and a tension roller '11, latter roller is j ournaled on brackets 12, secured to, the upright portion 6, below the brackets 7, as will, be clearly understood by reference to Fig. 2, of the drawing Just below the brackets 12, on which the roller 11, is journaled, is a pair of spaced rearwardly extending brackets 13, with which the upright 6, is provided on and between which is journaled the feed roller. On each of the brackets 7 is pivotally mounted for adjustable movement by means of a pivot pin 14, a bearing member 15, for the shaft 16, of the paper stopping attachment.

Each of the bearing members 15, is provided near its lower end with an arcuate slot 17, in which is located a thumb-screw 18, by means of which the position of each of the bearing members may be held in its adjusted position.

Mounted on the shaft 16, are a number of paper holding fingers 19, each of which isby preference made of rubber and has its lower extremity terminating in an arcuate end 20, which portion of each finger 19, will rest against the sheet 9, of paper and press it against the roller 14, as it passes thereover. Near its opposite end, each of the fingers 19, is provided with a transverse opening in which is preferably molded a circular bushing 21, of metal, or other suitable material. Each of the bushings 21, extends slightly to either side of the finger 19, in which it is lo cated, so that when the fingers are used in groups, or pairs, as shown in Fig. 1, of the drawing, each pair of fingers will be spaced one from the other.

It will also be understood that the fingers when grouped in pairs as shown can be held in such groups by means of pins 22, extended transversely through suitable openings in the shaft 16, adjacent the outer ends of the bushings.

While I have shown the shaft with a plurality of groups of fingers mounted in spaced relation thereon, yet it is obvious that a single pair only of the fingers 19, may be employed and the other groups dispensed with. It is also manifest that instead of using a plurality of fingers on the shaft 16, one finger only may be used. Whether one finger only, or one pair of fingers only are employed, it is by preference located at the central portion of the shaft 16, but when a plurality of pairs of fingers are used, it is desirable that one pair shall be located near each end of said shaft.

Particular attention is called to the position of the arcuate end 20, of each finger with respect to its shaft 16, and with respect to the shaft of the roller 14, over which the paper passes. It will be observed in Fig. 2, that as the bearings 15, are now located, the major part of the arcuate end of each finger 19. will be extended forwardly of a line drawn transversely through said shafts, and it will be understood further, that by this arrangement, as the fingers are loosely mounted on the shaft 16, they will act by gravity on the paper feed in holding it in position on the roller 14. As before stated the positions of the bearing members 15, can be adjusted on their pivots 14, by means of the slot 17, and screw 18, so that the most effectual position of the arcuate ends of the fingers, with respect to the roller 14, may be attained.

It is well known among those skilled in the use of bread wrapping machines, that it is desirable that the sheets cut from the feed should be uniform in size, and by my im- 5 provements this feature is attained, as it will be understood that the roller 8. and knife 23, may be located as closely together as desired, and as the paper will be securely held by the finger or fingers on the support for the paper, whether it be the roller 8, or otherwise, the paper will slide along the platform 5, till it passes under the knife 23, thereby being cut by the latter into sheets or pieces of uniform length and without the danger or liability of the paper back-lash mg.

It is obvious that the holding finger or fingers 19, will clamp the paper 9, in such a way as to cause its intermittent stoppage, 1

but also in such a way that it will be almost continuously fedunder the knife.

Having thus fully descrlbed my invention,

what I claim as new and desire to secure by Letters Patent is In a device of the class described. the combination with the paper supporting platform of a bread wrapping machine, of means for feeding paper thereover, means for cutting; the paper, a shaft journaled on the said machine horizontally and transversely, means depending from said shaft to rest on and hold the paper, said means having its paper contacting portion provided with an arcuate surface extending in the direction of the travel of the paper, and means for holding the said shaft in a back or forward position.
