HOLDER FOR ELECTRIC FUSES.
Application filed April 21, 1925.
o are.
A further object of the invention is the provision of a fuse holder which shall be adapted to permit the ready application or removal of a fuse, to establish a good electrical contact between the leads and the fuse, and to prevent the accidental displacement of the fuse.
A still further object of the invention is the provision of a fuse holder which shall be simple, durable and inexpensive of manufacture.
The foregoing and other objects are attained by the construction, combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawing, wherein:
Figure 1 is an elevational view of a fuse holder constructed in accordance with. my invention,
Figure 2 is a view in end elevation of the fuse holder,
Figure 3 is a transverse sectional view of the fuse holder, the section being taken on the plane indicated by the line 33 of Figure 1,
Figure 4 is alongitudinal sectional view of the fuse holder, the section being taken on the plane indicated by the line 4- 1 of Figure 1, and
Figure 5 a detail sectional view taken on the plane indicated by the line 55 of Figure 3.
Corresponding and like parts are referred to in the following description, and designated in the several views of the accompany inp drawing, by similar reference characters.
The fuse holder comprises a base 1 which may be made of slate, porcelain, marble or other suitable material. Metal strips 2 provided with outstanding ears 3 are secured to the base 1 in relatively spaced relation and are connected to binding posts 4 by conduc- Serial 1T0. 24,1;34.
When it is desired to either apply a fuse to or remove it from the holder, the cams 11 are swung out of contact with the movable jaws 7 and the latter swung away from the fixed jaws 6. The fuse 8 may now be readily positioned upon the fixed jaws 6 or removed therefrom without danger of forming an are. To secure the fuse in place, it is only necessary to swing the cams 11 in the direction of the fixed jaws 6. This carries the movable jaws 7 into contact with the ends of the fuse, and they may be held in contact therewith under the pressru'c necessary to establish a good electrical contact between the conductors 5 and the metal ends of the fuse 8.
It should be understood that the drawings are merely illustrative and do not pretend to give exact proportions. Furthermore, the
- able cams connected to the base and cooperating with the movable jaws to retain them in fuse clamping position.
2. A fuse holder comprising a base, fixed jaws connected to the base, movable ja s connected to the base, movable jaw actuating and retaining cams connected to the base, and a hand bar connected to the cams to simultaneously operate them.
8. A fuse holder comprising an insulating base, strips secured to the base and provided with ears, resilient relatively fixed jaws se cured to the strips, movable jaws pivoted to the ears, simultaneously operable cams conneoted to the ears for holding the movable 25 jaws in fuse clamping position, binding posts, and conductors connected to the bind ing posts and fixed jaws.
4. A fuse holder comprising a base of insulating material, metal strips secured to the base and provided with ears, jaws secured to the strips, other jaws pivotally connected to the ears, binding posts, conductors connected to he jaws and binding posts, cams of insulating material connected to the ears for cooperation with the pivoted jaws to hold'the latter in fuse clamping position, and a cam operating bar of insulating material bridging the cams to simultaneously operate them. 7
5. A fuse holder comprising a base, fixed jaws connected to the base, movable jaws connected to the base, cams of insulating material connected to base and cooperating with the movable jaws to hold them in fuse clamping position, and a cam operating bar of insulating material b a glng the cams to sii'nultaneously operate them.
In testimony whereof E my signature.
