To all whom it may concern:
Be it known that I, HARRY W. YOUNG, a
citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Electrical Fuse-Holders, of which the following is a specification.
My invention relates to improvements in electrical fuse holders and has for its object the production of a device of this character which will be of improved construction and efiicient in use.
Other objects will appear hereinafter.
ihe invention consists in the combinations and arrangements of parts hereinafter described and claimed.
The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,
Figure 1 is a perspective View of a fuse holder embodying my invention, Fig. 2 is a central longitudinal section of the holder, Fig. 3 is an enlarged transverse section taken on substantially line of Fig. 2, Fig. 4: is a side elevation of one of the half parts of the holder, exposing the inner side of said part, Fig. 5 is an end elevation of the holder, the samebeing shown closed in full lines and open in dotted lines, and Fig. 6 is a perspective View of the cotiperating cap members provided at each end of the fuse holder.
The preferred form of construction, as illustrated in the drawings comprises a tubular body which. is formed of a suitable insulating material. Said body is cylindrical in form and is constituted of two similar half parts 1 each of which is semi-circular in cross section. The parts 1 are lined within with a layer 2 of non-combustible material, asbestos being'preferably used in this connection. A transversely extending partition 3 of insulating material is provided within each of the parts 1 midway.
of the extremities thereof in order to divide the layer 2, the opposite ends of said layer being thusinsulated from or electrically independent of each other.
Provided at the extremities of the body of the holder are metallic caps, each of which comprises two similar half parts. 4 which are secured to the bodyparts 1 by means of rivets 5, as clearly shown in the several views. Prior to connection of the 1, the former are hingedly connected by means of cars 6, which are provided at corresponding edges of the capmembers i, said ears 6 being adapted to be interlocked with each other-by reason of slots 7 which are provided at saidears 6, as clearly shown in Fig. 6. After the interlocking of the ears 6 in order to form a hinge connection between the cap members 4. for each end of the body, said cap members are riveted to the body, as shown. When thus secured to cap members i to the respective body parts the body it will be seen that the parts 1 of the latter will be hingedly. connected and so that said parts may be swung to open position when desired for the placing of a fuse in or removing a spent fuse from the interior of said body.
Cotiperating cap members 4 and hence the body parts 1 are releasably locked in closed position by means of resilient engaging tongues 8 which are provided at the free" edges of one of the members 4 at each end of the body, the tongues 8 being adapted to pass through openings 9 provided in the adjacent sides of the cooperating members t and engage slots clearly shown in Figs. 3 and 6. The arrangement is such, as will be observed, that upon swinging of the members 4 to closing position, the ears 8 will automatically engage the openings 10 and thus effect the automatic locking of the holder in position.- The engaging extremities of the tongues 8 are accessible through the exteriorly opening slots 10 so that the same may be readily engaged by the finger nail or a pointed tool to move said tongues to disengaging position inorder to open the holder.
Formed integral with and projecting in- 10 provided therein, as-
wardly from the free edges of the cap'members 4 are fingers 11 which are adapted to serve as retainers for the fuse which is ar- .ranged in the holder, the inner or free ends .of said fingers being provided with grooves 12 which, when the holder is in closed position, are disposed substantially axially of the latter, for embracing the respective extremities of the fuse.
edge will traverse the V-shaped openlngwhich is constituted at each end of the Provided at the inner edge of the" end porholder between the inneredges of the heads or end Walls of the cap members, and serve as a means of supporting and centering a fuse arranged in the holder so that proper serve as cutting edges and effect the severing of the exteriorly pro ecting portions of the fuse, when the holder parts are rocked to closing position. The inner edge portions of the partitions 3 as Welles the corresponding edge portions of the layer 2 are recessed, as clearly shown in Figs. 2 oxide to permit of the passage of the fuse through the holder. The recesses, however, provided at the extremities of the layers 2 are comparatively small. so as to just permit of the passage of the fuse therethrough, a chamber thus being formed Within the holder which is complete'ly lined or surrounded-With non-combustible material. The cap members 4 will be formed of a conducting material, and so that in use the current Will be conducted from the fuse through the retaining fingers 11 to said cap members which may be supplied. with suitable means for connecting therewith the terminals of the conductor Wires of the circuit in which the fuse is in terposed.
- Nith a fuse holder of the construction set forth it will be seen that in the event of the use blowing out or becoming disabled, the same may be readily and expeditiously replaced by opening the holder in the manner above set forth. The holder by reason of the layer or lining 2 of noncombustible material is rendered substantially nonarchable and hence safe. The device may be manufactured at an exceedingly low cost,
and is'highly efiicient in use.
While I have illustrated and, describedthe preferred form of construction for car rying my invention into efi'ect, this is capebio of variation and modification without de-' parting from. the spirit of the invention. I,
therefore, do not wish to be limited to the to one end of one of said body members;-
cooperating locking catches on each pair of said caps removably securing said caps together; and resilient cooperating inwardly extending fuse holding arms of conducting material in each pair of said caps, each of said arms being; provided with a recess in its fuse holding port-ion; and complementary semi annular members in the central portion of said body members, each of said semiannular members being secured to one of said body members, substantially as described.
2. A fuse holder comprising a pair of complementary, semi-tubular body members of non-conducting material; a pair of complement-ary semi-circular caps of conducting material on each end of said pair of body members, each of said caps being secured toone end of one of said body members; co-
operating locking catches on each pair of said caps removably securing said capstogether; resilient cooperating inwardlyextending fuse holding arms of conducting material in each pair of said caps; and ears on certain of said semi-circular cap portions to edect longitudinal registration of said cap portions, substantially as described.
In testimony whereof I have signed my name to this-spemification' in the presence of two subscribing Witnesses.
