REPEATER OR MAGAZINE FUSE.

Application filed May 24, 1921.

To all whom t may concern Be it known that we, HENRY I. Drums, and JosErH B. HILL, both citizens of the United States, residing, respectively, at Millvale and Bellevue, both in Allegheny' County, in the State of Pennsylvania, have invented a new and useful Improvement in Repeater or Magazine Fuses, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, in which:

Figure 1 is a side elevation of a fuse embodying our invention;

Figure 2 is a section on the line II-Il oi? Figure 1; and

Figures 3 and 4 are sections, taken, respectively, on the lines III-III and lV-IV of Figure 2.

Our invention has relation to improvements in fuses, and more particularly fuses of the magazine or repeater type, in which there are a plurality of fuse members adapted to be successively brought into use asa fuse member previously in use becomes destroyed.

The object of our invention is to provide a fuse of this character which will be more simple in its construction and more convenient in its action than other devices ot this character with which we are familiar.

The nature of our invention will be best understood by reference to the accompanying drawings, in which we have shown a preferred embodiment thereof, which will now be described, it being premised, however, that various changes may be made in the details of construction, arrangement and combination of the various parts without departing from the spirit and scope oi' our invention as defined in the appended claims.

In these drawings the numeral 2 designates a fuse block or carrier, which is shown as of generally cylindrical form, and which is of some suitable insulating material, such as porcelain. It is provided at its respective ends with terminal members 3 and :l: ot' conducting material, and which are in the torm of screw caps which can be read- 0 il)7 screwed upon the threaded end portions at' the carrier.

5 designates the fuse members, which are removably seated in spaced relation on the carrier. In the particular device shown,

Serial No. 472,186.

cess 7 in the end of the carrier and also mak-` ing contact with oneof the terminals 3 or 4. The inner end of each fuse section is bent, as indicated at 8, and is engaged with a. recess 9 at the central portion of the ca rrier. Thetwo sets ot recesses 9 are separated from each other by the integral wall 10 of the porcelain body. The sections of the fuse members extend through the apertures 11 `formed in said body. The external portion of the body is cut away centrally, as indicated at 12, adjacent to the inner ends of the sections of the fuse members. A sleeve 13 is rotatably mounted on the carrierover the opening formed by this cutaway poition, being held in place by an inturned lip 15 at one end, which engages with the shoulder 16 of the carrier, and also by a spring .dog'17l secured to the sleeve and adapted to snap `into any one of a member of spaced depressions 18 formed in the outer peripheral surface, of the carrier. Each of these depressions is preferably numbered, as indicated in Figure 1, so that it can be determined at a. glance just which fuse is in useand how many have been used up.

The sleeve is shown as consisting of an inner metal lining with an outer covering of some` suitable insulating material, such as fiber. .The inner metallic lining of the sleeve has a cut and inwardly bent portion 19 which acts as a brush or contact to span the adjacent inner end portions of the two fuse sections of one complete fuse member and thus complete the fuse.

The operation will be readily understood. lV hen any fuse member becomes destroyed, the sleeve is rotated one step, thus bringing the nextpair of fuse sections into operation. and so on until all of the fuse meml` bers have been used. The terminal caps 3 and et can then be unscrewed and removed, together with the sleeve 13, and a new set of fuse sections can be inserted.

The advantages ot our invention will be apparent to those familiar with devices ot' this kind. It provides a magazine or ropeater fuse in which the i'use members are at all times in electrical Contact at both ends with the terminal members, but by reason of the divided character of each complete fuse member only that fuse is actively in circuit which is engaged by the contact device of the rotatable sleeve. This sleeve forms a very simple and convenientmeans of making contact'between the separated sections of the fuse members and of shifting from one tuse member to another. The device is thus free of complicated contact part-s 'of ya. character likely to become deranged and inoperative in use.

We claim:

l. A repeater or magazine fuse comprising a carrier having a plurality or" fuse mernbers, each of said fuse members being formed of two separated sections, and a movable contact device for spanning the gap between the sections of any 'fuse member, substantially as described. v Y

2. A repeater or magazine fuse compr1sing a carrier of insulating material having removable terminal members at its ends, and aplurality of fuse members removably seated in spaced relation on said carrier, each of said fuse members being termed in two sections, each section being in contact with one of the terminals and the two sections having separated end portions, together with a contact device adapted to span the se`parated end portions ot each fuse member and to be moved from one fuse member to another, substantially as described.

3. A repeateror magazine fuse comprising a carrier of insulating material, a terminal member removably engaged with each end portion of the carrier, said carrier having a plurality oi spaced seats tor Jfuse ele ments, a plurality ot fuse elements removably engaged with said seats, each of said elements being formed in two sections, each of said sections being in contact with one of the terminals at one end and having their opposite ends separated from each other, and a sleeve member rotatably mounted on the carrier and having a contact device adapted to span the gap between the ends of the sections ot any one of the fuse elements, substantially as described.

Ll. A repeater or magazine fuse comprising a carrier of insulating material, a terminal member of conducting material removably engaged with each end of the carrier, said carrier having a plurality ot seats for fuse elements and being cut away exteriorly at an intermediate portion, a plurality of fuse elements removably engaged wit-h the seats of said carrier, each of said fuse elements being formed ot two sections and each section having one of its end portions in electrical contact with one ot the terminal members, the opposite ends of said members being separated from each other, and a sleeve rotatably mounted on the carrier and over the cut-away portion thereof and having a contact device tor spanning the separated ends et the fuse sections, substantially as'described.
