MANDREL FOR TUBE-MAKING MACl-llNES.
SPECIFICATION forming part of Letters Patent No. 634,191, dated October 3, 1899.
Application filed October 20, 1898. Serial No. 694,072. (No model.)
paper-rolls produced by such mandrel as.
known to me the inner end of the strip is left projecting across the bore of the roll; and it is the object of my invention to cause the projecting end of the strip to be laid along the inner wall of the bore of theroll as the latter is pulled from the mandrel.
To this end my invention consists in a mandrel having a bore and a slit in its side leading to said bore and adapted to receive the end of a paper strip and a tongue projecting 2 5 into said bore to lie in the path of the end of the strip as the roll that. has been wound on the mandrel is pulled off from the same, said tongue acting to lay said projecting end of" the rolled strip against the inner wall of the 0 bore of the roll.
The invention also consists in the novel details of improvement and the combination of parts that will be more fully hereinafter set forth and then pointed out in the claims.
Reference is to be had to the accompanying drawings, forming part hereof, wherein Figure 1 is a perspective View of a mandrel embodying my invention. Fig. 2 is a section on the line 2 2 in Fig. 1. Fig. 3 is a section on the line 3 3 in Fig; 1. Fig. at is an end view of the mandrel, and Fig. '5 is an end view of a paper-roll before the inner projecting web is laid against the wall of the bore.
Similar numerals of reference indicate corresponding parts in the several views.
1 indicates a mandrel which may have screwthreads 2 or other means at one end for attaching it to a rotative supporting and drivcorresponding part of the wall of the mandrel .inwardly and by beveling the edge of the tongue from the part 7 toward the opening 5 along the edge 8. Thetongue 6 is bent inwardly on a curve, as shown in Figs. 3 and 4, and its inner edge 9 preferably lies transversely of the bore 3, whereby the tongue extends into the bore of the mandrel.
When the mandrel is being used, the end of a strip of paper is passed through the slit 4, and then the mandrel is rotated. This causes the end of the paper strip to be bent,
as at 10 in Fig. 5, and as the mandrel continues to rotate the strip will be wound on the same in convolute form, producing a roll 11, having a web 10 extending across its bore, as shown in the drawings. The roll 11 is next pulled from the mandrel, and in its passage along the same the web 10 will engage the tongue 6, and as it travels along the same the web. 10 will be pressed by the tongue back along the inner wall of the bore of the roll, whereby the bore will be clear and free. Paper-rolls thus produced are useful for firecracker bodies and other purposes.
Instead of making the tube or mandrel of hollow metal it can be formed from a solid bar or built up in any desired way.
Having now described my invention, what I claim is 1. A mandrel having a bore and a slit in its wall leading to said bore, and a tongue projecting into said bore, substantially as described.
2. A mandrel having a bore and a slit in its wall and also an opening in the wall at one side of said slit, and a tongue between said opening" and the end of the mandrel and projecting into said bore, substantially as described. V
A mandrel having a bore and a slit in its wall, and a tongue formed by bending thewall leading to said bore, and a tongue extending into said bore, the inner edge of said tongue extending transversely of the bore,
substantially as described.
(3. A mandrel having a bore and a slit in its wall leading thereto, and a tongue bent on a curve and extending into said bore, substantially as described.
Signed at the city, county, and State of New York this 17th day of October, 1898.
EDVARD O. TRUYTER.
