BUSHING oe ROLLS OF PAPER.

SPECIFICATION forming part of Letters Patent No. 737,407, dated August 25, 1903.

Application filed May 22,1903. Serial No. 158,817. (No model.)

To all whom, it may concern:

Be it known that I, MONTEFIORE LEWIS HIRSCH, a'citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented new and useful Improvements in Bushings for Rolls of Paper,of which the following is a specification.

My invention relates to cores for rolls of paper, and has for its object to provide simple and efficient bushings calculated to secure the centers of rolls of paper and at the same time form bearings for the rolls, so that the same may be turned freely upon shafts.

With the foregoing in mind the invention will be fully understood from the following description and claims when taken in connection with the accompanying drawings, in which- Figure 1 is a view illustrating two of my improved bushings in diametrical section as properly arranged in engagement with a roll of paper and on a shaft. Fig. 2 is an enlarged diametrical section of one of the bushings removed from the roll of paper, and Fig. 3 is a perspective View of the same.

Similar letters designate corresponding parts in all of the views of the drawings, referring to which-- A is a shaft such as ordinarily used to support rolls of paper, B a roll of paper, and C O my improved bushings for securing the center of the roll and forming bearings therefor, so that the roll may be turned freely on the shaft. The bushings are similarin construction, and therefore a detailed description of the one shown in Figs. 2 and 3 will suffice to impart an understanding of both. Said bushing is formed of one piece of metal or other suitable material and is provided with a smooth bore a, tapered or gradually reduced in diameter from its inner to its outer end, as best shown in Fig. 2. Exteriorly the bushing is tapered or gradually reduced in diameter from its outer end to its inner end and is flutedt'. a, provided with longitudinal ribs Z) I). These ribs 1) b are beveled at their forward ends, as indicated by c, to facilitate the placing of the bushing in a roll of paper, and the ribs 1), of which there may be four, (more or less,) merge at their outer ends into wings d, which are by preference of V shape in cross-section and have knife-edges e pitched at a greater angle'to the axis of the bushing than the major portion of the outer side of the bushing, this in order to enable said wings to readily take secure hold of the paper.

In practice the bushings are placed as shown in Fig. 1 with reference to a shaft and a roll of paper, when, as will be readily observed, they will secure the center of the roll and form bearings for the same, so that the roll may be turned freely on the shaft. The bushings in practice are made in various sizes to suit shafts and rolls of paper of different sizes.

I have entered into a detailed description of the bushing constituting the present and preferred embodiment of my invention in order to impart a full, clear, and exact understanding of the same. I do not desire, however, to be understood as confining myself to the bushing as shown and described, as such changes or modifications may be made in practice as fairly fall within the scope of my invention as claimed.

Having described .my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. A bushing for rolls of paper, exteriorly fluted and tapered toward its inner end, and interiorly tapered toward its outer end.

2. A bushing for rolls of paper, exteriorly tapered toward its inner end, and having wings provided with knife-edges, pitched at a greater angle to the axis of the bushing than the major portion of the outer side of the bushing.

3. A bushing for rolls of paper, exteriorly tapered toward its inner end, and interiorly tapered toward its outer end, and having a plurality of wings projecting from its outer side.

4. A bushing for rolls of paper, exteriorly tapered toward its inner end, and interiorly tapered toward its outer end, and having exterior, longitudinal ribs, some of which merge, at their outer ends, into wings.

5. A bushing for rolls of paper, exteriorly tapered toward its inner end, and having exterior, longitudinal ribs, some of which merge, at their outer ends, into wings; said wings being of V shape in cross-section, and hav- 10 knife-edges pitched at a greater angle to the axis of the bushing than themajor portion of the outer side of the bushing.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit-r nesses.

MONTEFIORE LEWIS HIRSOH.
