1933- A. L. REAGLES END CAP FOR PAPER CORES Filed Nov. 22, 1932 INVENTOR ATTORNEY at the rim and the other in the center.

Patented Oct. 3, 1933 I Q 1,929,036 'END car ron PAPER COBES Annie L. Beagles, Corinth, N. y., assignor to Elixman Paper Core-Co. Inc., Corinth, N. Y.,

a corporation of New York Application November 22, 1932 Serial N0. 643,805 I 2 Claims. (Cl. 242-68) This inventionrelates to end caps of the kind used on tubular cores on which rolls of paper are wound, and my object is to provide an end cap having two separate driving holes or sockets, one It sometimes happens thatin the paper factory the driving mechanism for the cores is of the type that engages in a slotprovided in the rim of the cap, whereas the consumer uses a drivingconnection adapted to engage in a central hole of the cap. Or, the reverse may be true, but in either case the consumer gets a paper core with an end cap unsuitable for his particular form of driving machine. It would be manifestly impractical to have each consumer or user of paper rolls provide his factory with both kinds of driving connections.

I overcome the above-mentioneddifliculty by constructing an end cap with a rim slotand a square (or equivalent) hole in the center, so that either form of drive may be employed. The novel features and practical advantages of my invention will be understood from a description of the accompanying drawing, in which Fig. 1 is an axial section through'one end of a core provided with my new end cap;

Fig. 2 is a transverse section on line 22 of Fig. 1; and 7 Fig. 3 is a fragmentary detail showing a plan view of the rim slot in the cap, this view being on line 33 of Fig. 1. V V

The cap comprises an outer sleeve 10, an inner sleeve 12, an annular web 13 connecting the outer ends of the sleeves, and a transverse web 14 extending from the inner end of the inner sleeve. These parts are shaped from a single piece of sheet metal, preferably cold-rolled steel. The concentric

cylindrical sleeves

10 and 12 are adapted to receive the end of a tubular core 15 in a tight fit, and the cap is secured in place by indenting the outer sleeve 12, as indicated at 16, or in any other practical way.

The transverse web 14 has acentral driving hole 17, preferably square, and the metal surrounding this hole is bent back to formintegral flanges 18 whichofl'er a sufficiently wide bearing surface for the square end of the driving shaft that enters the hole. In the case of extra-large caps, I may use a reinforcing washer 19 attached to the rear face of web 14 by rivets or spot-welding 20, or otherwise. The washer 19 has a square hole which fits snugly over the four flanges 18, thereby greatly strengthening the web.14.

The rim of the cap is cut away to provide a slot 21, which extends through both'sleeves 10 and 12 and through the end of core '15. The purpose of slot 21 is to receive a driving lug to rotate the core 15 for winding or unwinding a roll of paper. It should be noted-that the rim slot 21 is aligned with the square driving hole 1'7. That is to say (referring to Fig. 2), the sides of slot 21 are substantially par hole 17, so that either a allel with two sides of driving lug can be inserted in the rim slot or a square shaft in the central hole 17 without changing the radial position of the core.

especially in very large central and peripheral driving connections are F It is also possible to use the two

driving sockets

17 and 21 at the same time,

caps, where combined capable of exerting great power without danger to cap and cover.

Although I have shown and described a specifi structure, my invention is not limited to the details set forth, for changes and modifications may be resorted to without departing from the scope of the appended claims.

I claim as my invention:

1. An end cap for paper cores, said cap comprising a pair of concentric sleeves adapted to receive one end of a tubular core, at least one of said sleeves being recessed to provide a socket web extending from the having a central non-circ for receiving a driving member, and a transverse inner sleeve, said web ular opening adapted to receive a driving member.

2. An end cap for paper cores, said cap comprising a pair of concentric sleeves adapted to receive one end of a tubular core, said sleeves being slotted to provide a rim socket for receiving 3 a transverse web cona driving member, and

two sides of the square h ole.
