To all whom it may concern:

'Be it known that we, JoHN B. lVns'r and LOUIS J. WALZ, both citizens of the United States of America, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Apparatus for Heading Rolls of Paper, of which the following is a full, clear, and exact description.

In preparing a roll of newsprint paper for shipment, the customary practice is to wrap the roll in heavy paper wide enough to extend beyond the ends of the roll, and fold the overlapping edges of the wrapper inwardly and downwardly, after which a circular or disk-shaped head of stiff paper or light card is affixed to the infolded wrapper by means of glue or other suitable adhesive. In performing these operations the practice has been to affix one of the heads and then up-end the roll so that it stands on the headed end, after which the head is applied to the upper end of the roll and a heavy weight placed on top to hold the head in position until the glue or paste has set. Such rolls of paper are long and unwieldy, and also heavy, and it will therefore be seen that considerable labor is involved in the operations described, which involves handling a roll as long as six feet in some cases and weighing upward of 1200 to 1400 pounds. In fact it requires several work men to wrap and head a roll of paper properly, and moreover the work is slow as well as heavy. r

We have accordingly been led to devise our present invention, which has for its object to provide simple and effective apparatus by which one man can head a roll of paper with comparatively little labor and in much less time than formerly was required in the operation. To this and other ends the invention consists in the novel features hereinafter described.

In carrying out our invention in the preferred manner we provide a pair offlat abutmen'ts' to receive lengthwise between them the roll of paper which is to be headed, the abutments being movable toward and from each other to accommodate rolls of different lengths. 'Between the abutments, at the sides thereof, extend a pair of tensioning members which may be in the form of stout cables or chains, and associated with one of the abutments is a tensioning or binding member which is associated with the cables or chains in such manner that when the binding member is actuated the abutments will be drawn firmly against the ends of the roll. Preferably also the binding member mentioned is sov constructed and arranged that it will lock itself in the binding position thereby holding the abutments in position until the glue on the headers, which are suspended on the inner faces of the abutlnents, has set. The binding member can then be released from locking position and the abutments removed, leaving the roll perfectly wrapped and headed for handling or shipment.

The embodiment outlined above is illustrated in the accompanying drawing, in which Figure 1 is a side View showing awrapped roll of paper in position between the abutments before the latter are drawn up against the ends of the roll. Fig. 2 is a side view similar to Fig. 1 but showing the tensioning member rocked or thrown to binding position, with the heads pressed firmly against the infolded ends of the wrapper.

Fig. 3 is a plan view of Fig 2.

F ig, 4 is an end view from the left of Fig. 2.

Fig. 5 is a detail perspective view of one end of a headed roll of paper, with the head partly broken away to show the infolded edge of the wrapper.

For the sake of lightness and convenience in handling, the abutments l0, 11 are preferably made of wood as indicated in Fig. 4, strengthened, by vertical battens 12, 13, which are provided at their lower ends with feet 14, 15. These feet, which are turned outwardly to avoid possibility of damage to the roll of paper, may be made of short pieces of angle iron or pieces of bar iron bent to the proper shape. Across one of the abutments, as 11, is a bar 16, the ends of which extend beyond the sides of the abutment and are equipped with open hooks 17 to engage the tension members 18 which, as shown, may be in the form of chains, the terminal links of which fit over the hooks mentioned.

The battens 12 and 13 on the other abutment, 10, are provided with outwardly extending brackets 19 which are alined transversely, that is, their fiat upper surfaces are in the same horizontal plane, to receive the self-locking bar 20, which serves to put the chains under tension and draw the abutments toward each other. This bar 20 is flat in form, and when in the position shown in Fig. 1 it is supported on the brackets by its lower edge. The ends of the bar, which overhang the sides of the abutment, are provided with fingers 21, adapted to engage one or another of the links of the adjacent chain, according to the length of the roll between the abutments, as will be readily understood. As indicated in Fig. 1, these fingers are above the lower edge of the bar, preferably at the upper edge thereof.

At the center of the upper portion of each abutment is a stud 22 on which the heads, as 23, well coated near their edges with glue, paste, or other suitable adhesive, are hung. It is to be understood that these studs we tend inwardly, but little if any farther than is necessary to hold the heads in position, so as not to damage the roll of paper when the binding pressure is applied.

The roll having been wrapped and the edges of the wrapper folded inwardly, as

indicated at 24: in Fig.5, the abutments,

with the paste-coated heads in place, are arranged at the ends of the roll as indicated in Fig. 1, and the chains are hooked over the fingers 21. A forked handle or lever 25 is then set down over the fiat bar 20 and is rocked outwardly and downwardly, thereby swinging the bar 20 down fiat upon the brackets 19. As will be readily understood, this movement of the bar 20 draws the abutments toward each other, and thereby brings the heads 23 firmly upon the infolded edges of the wrapper. The brackets 19 and the hooks 17 being at the same or substantially the same height, it will also be seen that the rocking movement of the bar 20 brings the same into the plane of the chains, so that their tension exerts no tendency to swing the bar out of its locking position. In short, the bar in effect locks itself. As soon as the glue or paste or other adhesive on the heads has set, which usually occupies but a short time, the lever 25 is again applied to the binding bar 20 and the same is raised to the position of Fig. 1 by swinging the lever upwardly and inwardly. The chains can then be released at either end andthe abutments removed, leaving the heads attached to the wrapper, as indicated in Fig. 5.

Itwill be observed that during the above operations the roll does not have to be upended, and that if it has to be moved at all,

the necessary shifting can be effected by rolling it on the floor, which requires comparatively little effort. Also, the handling of the chains and abutments is not diificult and their arrangement in the proper positions can be effected rapidly and easily by one workman.

Metal wear-plates 26 may be provided on the battens just above the brackets 19 to protect the battens against wear which would be caused by the rocking movement of the bar 20.

The apparatus is not only simple and effective in use, but is also free from complication and can be constructed at comparatively small cost. At the same time it can be made strong enough to withstand use for an indefinite period.

It is to be understood that the invention is not limited to the specific details herein described and illustrated, but can be embodied in other forms without departure from its spirit.
