Patented Oct. 13, 1914.

Application filed October 13, 1913. Serial No. 794,843 I To all whom it may concern Be it known that I, JOSEPH C. HOFFMAN, a citizen of the United States, and a resident of New York, borough of Bronx, in the county of Bronx and State of New York,

- have invented a new and Improved Spool,

of which the following is a full, clear, and

I exact description.

The invention relates to spools, and has reference more particularly to spools made of pastebo-ard; and the object thereof is to provide a simple, strong and inexpensive spool in which the flanges and the central tubular. portion of the spool are rigidly connected. I obtain the above object" by providing a tubular member and flanges having the central opening substantially equal to the bore of the-tubular member, each of the flanges being secured to the tubular member by means of a member fitting tightly into the opening of the flange and the bore.

Reference is to be had to the accompanying drawings forming a part of this specification, in which like characters indicate corresponding parts in all the views and in which: 7

Figure 1 is a perspective view of an embodiment of my invention; Fig. 2 is an end view of the same; and Fig. 3 is a section on line 3-3, Fig. 2.

Referring to the drawings, 5 represents a tubular member, preferably of pasteboard, to the ends of which are connected flanges 6 of similar material by means of metallic.

tubular members .7. The central opening 8 of the flanges 6 is of substantially the same diameter as the bore of the tubular member 5 and the exterior diameter of the tubular member 7, whereby said member 7 is made to fit tightly into the opening 8 and the bore of tubular member 5. The metallic tubular member 7 which binds the flange t} to the tubular member 5 has at its outer end a lateral flanged portion 9 which draws the flange 6 to the tubular member 5 when the metallic tubular member 7 is made to engage the opening 8 and the bore of the pasteboard tube 5, as shown in Fig. 3. To prevent the rotation of the metallic tubular members 7 in the bore of the tube 5 and bind the same to it, the exterior lateral surface of the tubular member 7 is provided with a pair of parallel, circular grooves 10, and the surface between the said grooves is knurled so as to interconnect said grooves,

whereby the adhesive material with whibh the metallic member 7 is covered previous to itsdnsertion into the bore of the tube 5 receives a support and binds the tubular member 5 to the metallic member 7.

The lateral flanged portion 9 of the metal- 110 tubular member 7 has its faces waved,

'this being the result of the stampingof the tubular member 7 occasioned by the drawmg out of the cylindrical portion from a disk, of which the flanged portion 9 is the remainder, Due to the same cause, the edge 11 of the flanged portion 9 is unequally disposed from the axis of the tubular member 7; and this feature is utilized as will appear herei-nafter. In view of the fact that the flanged portion 9 has a wavy surface,

the adhesive material placed between the outer face of the flange 6 and the inner surface of the flange portion 9 will have a hold, due to the unevenness of the flange 9, and bind the flanged portion 9 to the pasteboard flange 6. This binding will prevent the rotation of the flange 6 the metallic tubular member 7, which, furthermore, will be resisted by the unevenness of the edges 11, as

previously described. The opposite or inner edge of the tubular member 7 is preferably reinforced by means of an end wall 12 having a central aperture 13. The reinforced wall or bottom 12 of the tubular member is preferably formed integrally with the tubular member 7 and flange 9. For very small spools the metallic member 7 can be formed without the reinforcing wall 12, if desired.

From the above it can be seen that the metallic member 7 has the shape of a cup having at the open end a lateral flange, so that the connection between the paste-board tube 5 and the flange 6 of similar material is obtained by'a metallic cup, the flanged portion of which prevents the movement of the flanges away from the tubular member; and the tubular member forms an abutment for said flanges on said cup and prevents their movement toward each other. As shown, each of the flanges is mounted on a .cup in contact with the flanged portion 9 of the same; and, similarly, the end of the tubular member is mounted on the cup so as to abut against the flange 6, and, therefore, force the flange 6 against the flanged portion of the cup.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. In a spool, the combination of a paste -to the bore of the tube, with metallic tubular members, each havmg a lateral flanged portion, each of said tubular members fitting tightly into the opening of each of the flanges and said bore of the pasteboard-tube, said metallic tubular members having means forming an anchor for adhesive material to secure the tubular members to the pasteboard tube, with said flanged portion of each of the metallic members contacting with the pasteboard flange.

2. In a spool, a tubular member; flanges having a central opening substantially equal to the bore of the tubular member; and a cup adapted to fit into each end of the bore of the tubular member and engage the central opening of each of the flanges and whereby said flanges are secured to the tubular member, each of said cups having means on the lateral surface thereof forming an anchor for adhesive material, whereby said cups are secured to said tubular member. Y

3. In a spool, a tubular member; flanges having a central opening substantially equal to the bore of the tubular member; a flanged cup for each end of said tubular member fitting snugly into the bore of the same and in the central openings of said flanges and whereby each of said flanges is secured to the opposite ends of the said tube, each of said cups having grooves in the lateral surface thereof formin an anchor for the adhesive material whereby the cups are secured to the tubular member.

4. In a spool, a tubular member; a flange ateach end of said tubular member, each of the flanges having a central opening substantially equal to the bore of the tube; a flanged cup securing each flange to the tubular member by tightly engaging the flanges opening, and the bore of the tube with the flanged portion of said cup against the face of the flange, said cup having in its lateral surface a pair of circular grooves and a knurled portion between said grooves,thereby forming an anchor for adhesive material to secure said cup to the tubular member.

5. In a spool, a tubular member; a flange at each end of said tubular member, each of said flanges having a central opening substantially equal to the bore of the tube; a flanged cup securing each flange to the tube,

each of said cups comprising a cylindrical portion adapted to fit snugly into the bore of the tube and the openings of the flanges, said cylindrical portion having means forming an anchor for adhesive material to secure the cup to the tube, the flanged portion of said cups having a wavy surface forming an anchor for adhesive material, whereby the cup is secured to the flange.

6. In a spool a tubular member a flange at each end of said tubular member, said flanges and tubular member having substantially equal bores; a cup securing each of the flanges to the tubular member, said cup comprising a cylindrical portion fitting snugly into the bores of said flanges and tube and having on its lateral surface two parallel circular grooves and a knurledportion between said grooves, said knurled surface and grooves forming an anchor for an adhesive substance whereby the cup is secured in the tube, said cup having also a lateral flanged portion, the surface of which is wavy, thereby forming an anchor for an adhesive substance to secure the flange to the cup.

7;In a spool, a tubular member; a flange at each end of said tubular member, said flanges and tube havingsubstantially equal bores; a on securing each flange to the tube, the said cup having a polygonal lateral flange the surface of w ich is wavy, thereby forming an anchor for adhesive material and whereby said flanges are connected to said cups, each cup having also on the lateral surface thereof .a pair of parallel circular grooves and a knurled portion between said grooves establishing connection between said grooves, said grooves and knurled portion forming an anchor for adhesive material whereby said cups are secured to said tube.

8. In a spool, a tubular member; a flange at each end of said tubular member, said flanges and tube having substantially equal bores; an apertured cup securing each flange to the tube of said cup comprising a cylindrical portion having a knurled portion fitting tightly into the bore of the tube and whereby the tube is secured to the cup, each of said cups having also a lateral flange at the open end adapted to be forced into the flange, the edge of said flange of each cup being of a polygonal shape and the surface of the same being wavy, whereby said flanges are prevented from rotation on said cups and secured to the same.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
