FUSE-MOUNT.

Specification of Letters Patent.

Application filed April 19, 1906. sol-a1 no 312,687.

l i l useful Fuse-Mount, of which the following is a specification, reference being had to the accompanying drawings, illustrating same.

My invention relates to means for clamping electrical fuses in place in suitable electrical circuits, and more particularly to spring clamping means adapted to automatically hold such fuses in place.

The principal objects of my invention are to provide improved spring clamping means for clamping a terminal of a fuse in place by placing the latter under binding stresses, to arrange the spring clamping means to increase the efiiciency of the connection with the fuse, and to provide durability and simplicity in such a device.

Referring to the accompanying drawings, illustratmg the preferred form of my invenmountings a projecting portion 11 is first inserted through a hole in the terminal portion t, somewhat larger than the portion 11, and then the other end of the fuse 9 is depressed into a slot in spring 7, which slot is adapted to tightly grip the fuse-terminal, and thereby securely hold same therein. When the, fuse is depressed in the direction of arrow 14, the

flexible contact-spring engages a portion of the metal terminal and is thereby placed under tension, so as to make good electrical connection with the terminal 10 and at the sametime produce a lateral stress thereon. This causes the projecting portion 11 to firmly engage the rigid portion 4 in the hole therein. The forces impressed on the fuseterminal 10 firmly secure the fuse in place and make a very eflicient electrical connection for same. The free end of spring 5 may be formed to conform to the terminal 10, if desired. The spring 7 firmly grips its termam 10 to prevent the lateral stress on the tion, Figure 1 is a side elevation of a fuse and l the clamping means therefor. plan view of Fig. 1 with the fuse removed,

The base 1, preferably of insulating mate rial, carries the two insulating mountingpieces 2 and 3. Mounting-piece 2 carries a rigid terminal portion 4 and a flexible spring member 5, preferably formed as shown and ri idly mounted to the mounting-piece 2. Tl ie terminal portion 4 is adapted to accommodate an electrical conductor leading thereto in any suitable manner.

Fig. 2 is a shown in Fig. 3,if desired. and Fig. 3 is a side elevation of a modified opposite end of the fuse from throwing the latter out of circuit.
