TOOL.

Application filed March 23, 1921. Serial No. 454,717.

Toall whom it may concern:

Be it knownthat we, JOHN L. Dyna and HENRY T. MACNEIL, citizens of the United States, and residents, respectively, of Balboa and Ancon, Canal Zone, Panama, have invented a new and Improved Tool, of which the following is a full, clear, and exact descri tion.

T 1is invention relates to improvements in tools, particularly to a'tool which is de signed to facilitate the handling of cartridge fuses. An object is to provide a de vice of this character, which will permit the insertion or extraction of cartridge fuses into or from a fuse clip without the slightest danger of injuring the operator.

A further object is to obviate the danger of causing short circuits or grounds when inserting a fuse or withdrawing it from the clip.

A still further object is to provide a tool,

which will be simple and practical in con-- struction, strong and durable in use and comparatively inexpensive to manufacture.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts, to be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings:

Figure 1 is a view in side elevation of our improved tool, the dotted lines indicating the position of the sliding member when it is moved to engage a cartridge fuse;

Figure 2 is a top plan view in Figure 1, the dotted lines indicating a fuse within the cartridge;

Figure 3 is a view in side elevation illustrating the sliding member in another position; and I Figure 4 is a view in transverse section on the line 44 of Figure 1.

Referring in detail to the drawings, our improved tool comprises a pair of elongated super-imposed parallel members 1 and 2 mounted for axial sliding movement relative to each other. Each member includes a flat face 3 engaging the fiat face of the other member.

Both members are preferably of the same width throughout their length, but the member 2 may be appreciably thicker at one end than the member 1, as indicated at 4..

The legs 5 of U-shaped guide brackets such as 6, straddle the members 1 and 2 adjacent each end and are secured to the member 2 by rivets 7 or other suitable securing devices.

The brackets 6 serve to guide the sliding movement of the member 1 upon the member 2 and the intermediate portions of the brackets are spaced suflicient distances from the member 2 to permit a slight lateral movement of the member 1, as seen most clearly in Figures 1 and 4:.

A lug 8 extending inwardly from the intermediate portion of one of the brackets 6 is accommodated in a longitudinal groove 9 in the outer face of the member 1. The groove 9 and the lug 8 cooperate to limit the sliding movement of the member 1, as will be readily understood.

A pair of knurled thumb receiving grooves 10 are provided in the intermediate portion of the face of the member 1 to facilitate its manual operation. Adjacent one end, the flat face 3 of the member 2 is formed with a relatively deep curved recess 11. A shallow curved recess 12 on the fiat face 3 of the member 1, cooperates with the recess 11 to receive a fuse, indicated in dotted lines at 13. The adjacent inner end of the member 1 is of the curved shape illustrated at 1 1 to facilitate its slidingl movement over the fuse.

he other ends of the members 1 and 2 are formed with opposed recesses 14 and 15 respectively, also adapted to receive a fuse of smaller size. The recesses may of course, be of any size which will conveniently accommodate a standard fuse.

The members 1 and 2 may be of any insulating material, which is found suitable for the purpose.

Although we have illustrated one of the preferred embodiments of the invention, it will be apparent that various slight changes and alterations might be made in the general form and arrangement of the parts described without departing from the invention and hence we do not wish to limit ourselves to the precise details set forth, but shall consider ourselves at liberty to make adapted to receive a fuse,

such slight changes and alterations as fairly fall within the spirit and scope of the appended claims.

e claim:

1. A tool of the character described, comprising a pair of superimposed elongated parallel members mounted for axial sliding movement relative to each other, and having coacting recesses in their meeting faces adapted to receive a fuse.

2. A tool of the character described, comprising a pair of superimposed elongated parallel members mounted for axial sliding movement relative to each other, and having coacting recesses v in their meeting faces and means limiting the members.

the sliding movement of comprising a pa1r 3. A-fuse handling tool,

of superimposed elongated parallel mem-' bers, said members formed of insulating material, and slidable axially relative to each other, guide brackets straddling one member and fixed to the other member, said members having coacting fuse receiving recesses adjacent each end and means associated With the brackets limiting the sliding movement of one member on the other.

4:. A fuse handling tool, comprising a pair of superimposed elongated parallel members, said members formed of insulating material, and slidable axially relative to each other, guide brackets straddling one member and fixed to the other member, said members having coacting fuse receiving recesses adjacent each end, -*a lugextending inwardly from the intermediate portion of one bracket and said slidable member having a groove in its outer face receiving the lug.

5. As a new article of manufacture, a fuse handling tool, comprising two superimposed slidable one upon'the other and havingco? acting curved recesses therein adapted to receive a fuse.
