MOUNTING FOR FUSES.

SPECIFICATION forming part of Letters Patent No. 581,455, dated April 2"?, 1897.

Application inea september 19,1896. serai No. 606,342. ea man.)

To all whom t may concern:

Be it known that I, WILLIAM W1 DEAN, a citizen of the United States, residing at the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Mountings for Fuses, (Oase No. 11,) of which the following is full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to a mounting for fusewires, and has for its object to provide convenient means for attaching the fuse-wires to the fuse-blocks and removing them therefrom without danger of straining or breaking even the Inost delicate wires.

In accordance with my invention a length of fuse -wire is provided with a metallic mounting at each end,which I designate fuseterminal. These fuse-terminals are shaped in such wise that they may be grasped by the jaws of a wrench, which is designed to hold them firmly while inserting them into a spring clip or clips forming a part of the fuseblock, when they may be released from the wrench, leaving them tightly held by the clips referred to, which form the terminals of the conductor to be protected by the fuse. Throughout this operation all strains come upon the metallic fuse-terminal instead of upon the fuse-wire, whereby all danger of breaking the fuse -wire is obviated. The mounted fuses are packed for shipment with the fuse-terminals inserted in slots provided in a block of wood, from whence they Inay be withdrawn by the wrench.

The method of mounting the fuse-wire upon the metallic fuse -terminals and inserting the latter into the blocks for shipment is described and claimed in my application, Serial No. 606,343, led September 19, 1896, and forms no part of the present application.

I will describe my invention more in detail by reference to the accompanying drawings, in Which- Figure 1 is an elevation of a 'fuse-block and wrench embodying my invention, the ends of the fuse being provided with metallic terminal mountings in accordance with my invention, which are engaged by metallic springclips upon the fuse-block. Fig. 2 is a plan of the same. Fig. 3 is a plan View showing the wrench grasping the fuse-terminals, said terminals having been placed in engagement with the spring-clips through the agency of said wrench. Fig. e shows the fuse-terminals held by the jaws of the wrench in the act of being inserted within their engaging springclips. Fig. 5 is a detail perspective view of the two fuse-terminals with the fuse-wire mounted between them. Fig. G is a detail en d view of the wrench with the'fuse and terminals inserted therein. Fig. 7 is a similar view, the vfuse-terminals being removed. Fig. S is a perspective view of the block in which the fuses are packed and shipped.

Like letters refer to like parts throughout the several figures.

The conductors a o, which it is desired to protect by the iuse, are soldered to the ends of the spring-clips l) l), which are mounted upon the block g of insulating material. Each spring-clip is formed of a strip of metal which is provided with two cuts extending lengthwise thereof, as shown, which separate the spring-clip into three spring-fingers, the fuse-terminal being engaged between the central finger upon one side of the plate and the outer fingers upon the other side of the plate, as shown. rIhe metallic fuse-terminals c c are shaped as shown most clearly in Fig. 5, each having arms c c formed thereon, between which an ear cl is bent at a right angle thereto, one end of the fuse-wire d being soldered to the ear of one terminal, the other end of the wire being soldered in like manner to the ear c2 of a similar terminal. The ilat ends c3 of the terminals are adapted to be engaged by the spring-clips l) l) of the fuseblock, and it is these ends which are inserted in the slots of the wooden block e, Fig. S, in which the mounted fuses are packed fortransportation.

1Wrenches are employed for manipulating the fuses and the terminals to which they are secured. In order to preserve a fixed relation between the fuse-terminals to prevent the rupture of delicate fuses connected between the same, I provide each wrench with two receiversf7 as I term them, between which a Iixed distance is preserved, each receiver being adapted to secure a terminal in ICO position, whereby a fixed relation is preserved betweenthe fuse-terminals and the rupture of the fuse prevented.

The wrench is preferably 'formed with i'our holes in its ends, into which the arms c of the fuse-terminal are adapted to lit. Jaws f f', pivoted at juf?, are provided, the projections or teeth ffg whereof are designed to grasp the ears c2 c2 of the fuse-terminals c to hold the terminals iirmly in the wrench when the jaws are moved together by the lingers, as shown in Fig. Springs g f/ serve to keep the jaws f f normally apart, each pair of holes ff, that receive the arms c/ c of a fuseterminal, constituting` a receiver for that terminal, the jaws ff/ being provided to preserve the disposition of the terminals within the receivers.

The fuseterminals are disposed iOr shipment or storage in wooden blocks c, the ends c3 Of the terminals being inserted within slots d. In removing the terminals and fuse from the block e preparatory to engaging them with the fuse-block clips the wrench is thrust upon the fuse-terminals c c. The arms c c' it into the holes f f of the wrench. The jaws f of the wrench are closed together, the ends f3 whereof are thereby caused to grasp the ears c2 Oi the fuse-terminals, which may now be withdrawn from the block c and thrust into engagement with the spring-clips upon the fuse-block, as shown in Fig. 3. rlhe jaws f' are then released and the wrench withdrawn, leaving the fuse-terminals engaged by the fuse-block clips, as shown in Fig. l.

It is evident that modiications may be made without departing from the spirit of my invent-ion.

Having thus described my invention, I therefore claim, with only those limitations expressed or implied in view ot' the state of the related arts, the following:

l. In a fuse-terminal, the combination of the end c, and arms cl c', with an ear c2 to which the fuse-wire may be attached located between said arms and bent at an angle thereto, substantially as and for the purpose described.

2. The combination of a fuse, with terminal plates io which the same is attached, said plates having ends c3, arms c c', and cars c2, substantially as described.

In a wrench for manipulating fuse-terminals, the combination of jaws f f adapted to grasp said terminals, with a recess Or recesses ff provided in a lixed portion OE said wrench adapted to receive a portion of each of said terminals, substantially as described.

4L. In a wrench Afor manipulating fuse-terminals, the combination of a 'Fixed portion adapted to engage said terminals, with pivotall y-sin 3poited jaws adapted to grasp said terminals, and springs adapted to separate said jaws, substantially as described.

5. In a wrench for manipulating fuse-terminals, the combination of a fixed portion provided with recesses fj" adapted to receive said terminals, with jaws adapted to grasp said terminals, substantially as described.

In witness whereof I hereunto subscribe my name this 'lGt-h day Of September, A. D. 180o'.
