masses To aZ whom it may concern:

Be it known that 1, WILLIAM A. NORMAN,

a citizen of the United States, residing at handling of roll-paper.

Chicago,in the county of Cook and State of Illinois, have invented a certain new and useful ln'iprovement in Roll-Paper Shoes,

of which the following is a specification.

My invention relates to shoes for the It will be understood by those familiar with the print paper trade that there is mumm a tremendous loss in CODIIGCtlOlTWltlI paper rolls due to the crushing of the edge of the paper when the roll is tilted during handling. Much of.

the press.

of paper. the chord of the are formed by the pethe roll print paper, especially that intended for newspaper-work, is comparatively thin and tender and the edge of the paper crushes when the roll is tilted up on edge in putting it in or out of the freight cars and in preparing to place the roll in The object of my invention is to provide simple and efficient means for protecting the paper and distributing the weight over a considerable portion of the roll thereby rendering it possible to tilt the roll as frequently as desired without doing any damage to the paper.

I accomplish my object by the device shown in the accompanying drawings, in which Figure l is a perspective View thereof.

Fig. 2 is a transverse section thereof on the line 22, Fig. 1.

Fig. 3 is a side elevation of a roll showing my shoe applied thereto.

.Erlimilar numerals refer to similar parts throughout the several views.

The shoe consists preferably of sheet steel and may be one-sixteenth of an inch thick more or less. In the form shown, it con sists of two pieces, a sole 1 and a back 2. When, viewed in plan the outer edge of the sole conforms to the arc of a circle and the inner edge 1 is sharpened to a dull edge to facilitate itsinsertion under the rolls This inner edge is parallel to riphery but lies closer to the center of curvatime and therefore is wider than a mere segment of the arc would be. This affords more area and also facilitates insertion under the roll. In other words, the sole curves toward the center at the ends 1 and hence the width of the shoe from the inner edge 1 to the arc 1 is greater than it would otherwise be.

Specification of Letters Patent.

Serial No. 54,107.

The outer edge of the sole is turned up to form a flange 1 which is riveted or otherwise securely fastened to the lower edge of the back 2 and backs up the portion 2, as

shown in the drawings. This results in two advantages; first, all strain on the rivets is removed, for the weight of the rolls when tiltlng tends to keep the back and the flange in contact; second,'an extra quantity of material is afforded at the corner where the greatest stress occurs and'hen'ce the life of the device is greatly prolonged. There is another advantage arising from the fact that the flange is integral withthe sole as there is no danger that the partswill become separated in use.

The back when viewed 1n elevation is approximately triangular, the center point 2 being highest and being preferably approximately six inches high. The ends 2* do not descend to the level of the sole but have vertical ends which are approximately two inches high. The back is curved outward at the points 2 and 2 the purpose being to prevent at all hazards these points from cutting into the side of the roll. I have found. that by rounding these slightly backward, the paper will he supported without damage of any kind.

Operation: My shoe is intended for use only at those critical moments when the roll is being tilted up either during shipment or at the time when the roll is to be set in the printing press. It is intended simply to dis tribute the strain due to the weight of the roll over a large surface and hence enable the delicate paper to withstand the stress to which the roll as a whole is subjected upon the occasions mentioned. Let it be assumed that a roll is standing upright in a freight car. In order to put it upon a truck it must be laid partially or entirely upon its side. In emplnying my shoe, when the roll is to be tilted, the operator first lays the shoe on the floor near the roll. He then exerts a slight pressure sidewise against the roll near the top thus causing it to release part or all of its weight at that point from the floor but without actually tilting the roll. This lifts the weight sufliciently to enable the operator to apply the shoe and slip it under in position by the aid of his foot. The forward or inner edge of the shoe being sharpened, readily finds its way under the roll. When the shoe has been inserted as far as it will go and the back 2 is in contact with the side of the roll, the roll may be tilted, whereupon the shoe Will tilt With it and the Weight of the roll Will be distributed overthe entire .curvatureof thecurvature of the periphery sot-the shoe. Inany case the end of the roll 1 -.Will bear, upon the entire surface of the sole of the shoe and willbear upon a considerable ;.a rea of-ftheback, for my shoe is so constructwedfthat the curvature .ofits periphery con- --J"iorms to the curvatureof vthe commonestsizes-10f roll. Zhen the roll has been tilted i"a1' .enougl1 foreits-Wejght to be carriedby the-truck or the paper holder of the press,

:theshoe is no longer needed and falls away.

From the. foregoing it will be evident that this,article; ie-extremely simple and yet prehve its the crushing of the. paper Which is the occasion of such an important percentage of loss in practically every shipment of paper that is made. The article is of great durability and infact is indestructible in the ordinary sense of the term; Furthermore, it accommodates itself to rolls of different diameters and requires no attaching means nor fastening devices during its use. Having thus described my lnvention, What I claim as new and desire to secure by Let ters Patent, 1s:

A. shoe whereby rolls otprint paper :may

be-supportedon edge Without damage, said shoe having a; flat sheetmetal sole for contacting thewend of the roll, the outer periphery-of the sole being circular and. having an upstandingintegral flange, and a sheetz metal back r1s1ngirom saidsole and being fastened to theainside of. said flange whereby the device ,is; reinforced at the ,corner said back being cylindrical except atathe top Where it is curved outwardly to prevent digging into the-sides of the roll.

In Witness whereof, I; have hereunto subscribed my name.
