Application filed August 5, 1912, Serial No. 713,262. Renewed March 3, 1916. Serial No. 82,001.

To all whom it may concern:

Beit known that I, ELMER M. COBB, of South Portland, in the county of Cumberland and State of Maine, have invented certain new and useful Improvements in Magazines for Feeding and Storing Rivets, of which the following is a specification.

My invention relates to a magazine adapted to be used for containing a definite number of rivets and for delivering the same one at a time when needed. The magazine is designed particularly to be used in connection with a riveting machine which is to be the subject of a later application but it is adapted to be used for other purposes or wherever it is desired to store and feed rivets or any similarly shaped articles.

The magazine is intended as a holder or container in which the rivets may be stored and shipped and put on the market for the use of said machine and at the same time it is designed to act as a feeding device which may be applied to the machine delivering the rivets one at a time to replace those used.

My invention may best be understood by reference to the accompanying drawing, in which is shown one form of magazine constructed according to my invention.

In. the drawing, Figure 1 is a vertical section through the magazine taken on the line a; 00 of Fig. 4:, Fig. 2 is a plan of the same with the cover left ofi, Fig. 3 is a part elevation and part section on the line 3 11 of Fig. 4 with portions of the casing cut away to show the spiral guides, Fig. 4: is a plan of the bottom of the casing showing the chute in section on the line 50 m of Fig. 1, and Fig. 5 is a section on the line 1 1 of Fig. 1.

Referring to the drawings. A represents a cylindrical casing in which is arranged a spiral guide which is adapted to support the rivets f on their sides and to form an inclined run-way by which they may roll from top to bottom.

As here shown, the spiral guide designated generally as B, is formed of a spiral strip T-shaped in cross section with a stem portion or single flange b horizontally disposed and the double flanged portion Z) vertical. The upper edge of the vertical. por tion 5 forms a spiral run-way for the rivets and the lower portion forms a guide for the rivet head. The flange 12 fits in a spiral internal groove a formed on the inside of the casing and it also forms a guide or runway for the edge of the rivet head and in conjunction with the upper edge. of the flange 6 supports the rivet in a horizontal position, the small end pointing inward.

The pitch of the spiral is such that the rivets will roll freely from top to bottom. A cover a is provided for the top of the cylinder and this cover is provided with a flange, a portion of which is bent inward at a to form a stop which abuts against the upper end of the spiral gui le B. A base or bottom head a is provided with an outlet opening at placed opposite the lower end of the spiral guide through which opening the rivets drop as they reach the bottom of the guide. The cover a and the bottom head a are preferably securely fastened to cylinder A.

A shut-off is provided by which the opening a may be closed when the magazine is being transported and rivets are not to be used.

As here shown, a shut-off platee is pivoted at the center of the bottom head a (shown in dotted lines in Fig. 4:). One end is broadened out to form a shut-off for closing the narrow portion of the opening a and the opposite end is turned down to form an operating handle 6 which travels in a slot 6 An upward extending flange or stop a on the shut-off 0 serves as a guide for the rivet bodies when the rivets are discharging and it also serves to close the lower end of the run-way when the opening a is closed to hold the rivets in place on the guides. The cylinder is supported in an upright position by suitable means.

As here shown, the upright support is utilized to hold the cylindrical casing together. The adjacent edges or flanges a of'the casing are bent outward in a diverging position to form a tongue which fits within the standard d. The standard d is triangular in section and forms with the flanges a a dove-tail connection whereby the cylinder may he slipped into the standard from above. The cylinder is both held together and supported in a vertical position by this locking arrangement.

The lower end d of the standard is enlarged and extended laterally to form a chute into which the rivet falls after it passes through the opening a and within which the rivet head loosely fits. The body of the rivet projects through the slot or opening 03 This chute or guide may be extended and carried to the place where the rivets are to be delivered as desired.

In using the device the magazine is filled with the rivets, and the shut-off is then closed. It is then attached to the support and the shut-off opened, allowing the rivets to run down through the chute. The magazine forms a convenient package in which to supply the rivets to the trade as it is only necessary to attach it to the machine and when empty throw it away or return it to be refilled.

It may be used as a magazine or reservoir in any position where it is desired to feed rivets or similarly shaped articles one at a time. It has considerable storage capacity and may be made as large in diameter and as long as desired.

I claim c 1. In a magazine for storing and feeding rivets and other articles of similar shape, the combination of a stationary, vertically disposed cylindrical casing and a fixed spiral guide in said casing constructed and arranged to support the rivets in a horizontal rollable position on their sides.

2. In a magazine for storing and feeding rivets, the combination of a stationary, vertically disposed cylindrical casing and a fixed spiral guide on the inner surface of said casing, said guide being T-shaped in cross section and being placed to support the rivets on their sides.

3. In a magazine for storing and feeding rivets, the combination of a stationary, vertically disposed cylindrical casing and a fixed spiral guide in said casing, said guide having a T-shaped cross section with the stem portion horizontal, the edges of the vertical portion forming a spiral track for the bodies of the rivets to roll on and a spiral flange to guide the rivet heads.

I. In a magazine for storing and feeding rivets, the combination of a cylindrical casing having a spiral groove therein and a spiral guide T-shaped in cross section with the stem portion horizontal, the stem p0rtion fitting said spiral groove and being held thereby.

5. In a magazine for storing and feeding rivets, the combination of a cylindrical casing, a spiral guide within said casing constructed and arranged to support the rivets in rollable position on their sides, the lower end of said casing having a discharge opening for said rivets and a shut-off for closing said discharge opening.

6. In a magazine for storing and feeding rivets, the combination of a cylindrical casing having adjacent longitudinal edges bent outward divergently to form a dove-tail tongue, an upright support for said casing having a longitudinal recess into which said tongue may slide and a spiral guide within said casing constructed and arranged to support the rivets in a rollable position.

7. In a magazine for storing and feeding rivets, the combination of a cylindrical casing having adjacent longitudinal edges bent outward divergently to form a dove-tail tongue and having a discharge opening in its lower end, and an upright support for said casing having a longitudinal recess into which said tongue may slide, the lower end of said support being enlarged and extended beneath said opening to form a chute to receive the discharged rivets.

8. A magazine for storing and feeding rivets including a cylindrical casing and a spiral guide constructed and arranged to support rivets horizontally on their shanks, said guide consisting of a flange vertical in cross section arranged spirally within said casing, the turns of the spiral being so close that the lower portion of the flange at any given turn acts as a guide for the upper portion of the rivet head when the rivet is on the next lower turn.

In testimony whereof I have affixed my signature, in presence of two Witnesses.
