FABRIC-ROLL PROTECTOR.

To all whom it may concern:

Be it known that I, CURTIS J. ROTI-IERMEL, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Fabric-Roll Protectors, of which the following is a specification.

My invention relates to an improvement in the class of protectors, in the form of dish-shaped metal disks, or heads, for the opposite ends of tubular rolls of roofing paper, and the like, and tied together by a rod extending lengthwise through the roll, used for reinforcing the end-portions of the latter against crushing. The roll of roofing paper is also utilized as a container for the shipment of packages of nails, caps and cement in quantities sufficient for fastening the predetermined quantity of the paper forming the roll in its place of use, the pack ages being stored in the tubular roll.

My present invention is an improvement, more particularly, on the device of United States Letters Patent No. 825,239, dated July 3, 1906, to overcome certain defects therein hereinafter mentioned and which the extensive adoption of the device, of which I have introduced several millions of sets intouse, has made apparent that it is desirable to avoid. The construction referred to is practically that shown in Figure l of the aforesaid patent,.but dili'ers therefrom, mainly, in the dish-shaped head being single, or devoid of the outer plate, but about as shallow as the depth to that plate.

One of the objections referred to is due to the difficulty of inserting the hooked end of the tie-rod through the hole in the lower head provided to receive it, after the stemportion of the rod has been inserted through another hole therein, because of the trouble and time required in striking or finding the hole for the hook. The adjustment of the heads is effected by placing the roll, on end upon the rod-carrying head and thereupon applying a head to the upper end of the roll and tightening and fastening the rod with a nut at its protruding end. Another objection is due to the tendency of the rod to drop in the assembling position referred to, thereby withdrawing the hook from the hole through which. it was inserted and requir ing the setting to be performed anew, with consequent loss of time. To obviate this last-named difiiculty floor-blocks are some- Specifieation of Letters Patent.

times used, but not always effectively. When it is considered that these protectors must be supplied at avery small margin of profit to the manufacturer, to enable manufacturers of the rolls to equip them therewith without additional cost to their customers, it will be realized that any difliculty in. assembling the parts which adds, even slightly, to the cost of performing the work is objectionable and liable to be more or less prohibitive of employing the means causing it, however desirable the same may be otherwise; and, on the other hand, any material improvement, however slight, tending to minimize that cost, is welcome.

The object of my improvement is to provide a construction of protecting means of the kind referred to whereby the objections mentioned, and other objections, shall be entirely overcome; and to that end I have devised the construction illustrated in the accompanying drawing, in which Fig. 1 is a longitudinal section of a roll equipped with myimproved protecting means; Fig. 2 is an enlarged outer-face View of my improved protecting head; Fig. 3 is a section on line 3, Fig. 2, and Figs. 4 and 5 are sections taken, respectively, on lines 4 .and 5, Fig. 3, and viewed as indicated by the arrows.

The roll 6 containing the central l0ngitudinal opening 7 is intended to represent a tubular roll of roofing paper, which it is customary to cover, for shipment, with wrapping-paper 8 and protect at the ends with sheet metal disk like heads tied together by a rod extending through the roll, which holds for shipment with it a package 9 containing nails and caps and a can 10 of cement.

The protector-head 11, which is shown to be (though it need not be)the same for each end of the roll, is a sheet-metal dish-shaped disk having a circumferential flange 11 about a tapering cupped center 11 The feature of novelty in the construction of the head is that of providing the base of the part 11 with a transverse bearing 12 extending from an insertion-opening 12 near the edge of the base to an opening 12 at or near the center thereof. This bearing may be best formed, in stamping out the head, by depressing a longitudinal section of the head-base to form a ridge, preferably of the concavo-convex shape in cross-section illustrated, with its convex side on the face of the base which is innermost when the protector is in its position of use, at the same time depressing concavo-convexly in the op posite direction sections of the base at the opposite ends of the first-na1ned ridge to form reverse continuations thereof, and pro viding the holes 12 and 12 between the ends of the intermediate ridge and the adjacent ends of the said continuations. formation of bearing enables a tie-rod 13 to be used when provided on one end with a section 14 extending at a right-angle, thus adapting that section to be formed by a single bend in the rod for insertion through the holes into the bearing. The rod is slightly deflected from a straight line, as shown and for the usual purpose, to incline from about midway its length toward its upper end, where it is threaded at 15 for the application of a nut 16.

To equip a roll 6 with my improved protectors the rod is inserted at its section 14 into the bearing on one head 11 and the roll is then placed in upright position 011 that head to be supported vertically there- 011 with the rod extending through the opening 7, and another head 11 is applied to the upper end of the roll in a manner to cause the threaded end of the rod to project through the central opening 12 in the base of that head, when the nut 16 is applied to draw the opposite heads firmly together. If desired, instead of securing the rod with a nut, its protruding end, which may then be unthreaded, need be merely bent to or toward a right-angle to fasten the heads in place. Before applying the upper head, packages 9 and 10 may be introduced into the roll, and confined therein by any suit able means against displacement in handling the roll.

The advantages of my improved construe tion of head relative to that of the head heretofore provided, as hereinbefore described, are manifold. The bearing 12 enables the supporting section 14 of the rod to be connected with a head 11 expeditiously and without difficulty, and it adapts the head to carry the rod, before and while assembling the parts to produce the protected roll, without tendency of the rod to become displaced, since the section 14% is held between its ends by the central ridge of the bearing and at its ends by the depressed cont-inuations thereof against dropping out. The improvement therefore enables any number of heads to be equipped with the rods to be taken, as required, and used, without resetting the rods, in finishing a plurality of rolls, thereby greatly expediting the work, and without requiring the use of head-blocks, thereby saving the expense This thereof. Moreover, the strain in tightening the rod does not, as in the former construction, tend to tear the base of the head along the line of the bent end of the rod engaging it; and the upwardly-projecting end of the hook in the former construction is omitted, with the advantage of avoiding presentation at the base of the roll of a projection into its opening 7, where it is liable to puncture either package 9 or 10 which is first dropped into the roll in assembling the parts as described. Furthermore, the use of my improvement enables the roofing or saturating machine, as the machine is called for making roofing-paper, to be run at its full capacity, with the resultant economical advantage, while with the aforesaid former construction of protector, the relative slowness of assembling the parts of a protected roll of roofingpaper so limited the quantity of the paper that could be handled as to render necessary running the machine far below its capacity.

What I claim as new and desire to secure by Letters Patent is 1. A fabric-roll protector comprising a pair of head-plates adapted to engage the ends of the roll and consisting of a dishshaped disk, one of which is provided in its base at one side of its center with an inwardly-projecting hollow ridge and an outwardly-projecting hollow ridge at each end thereof with insertion-openings at said ends, said ridges forming a bearing extending crosswise of said base, and a tiered having a single laterally-bent end-section adapted to pass through said openings for confinement in the bearing, said rod being adapted to extend lengthwise through the roll and protrude at its upper end through the head thereon and be fastened thereat.
