The invention relates to electrical plugs and fuses and more particularly it relates to a combination electrical plug and fuse suitable for insertion in a socket to supply energy for a lamp or for a radio, and for general use.
The invention contemplates the provision of an electrical plug of the kind d'escnbed having a plurality of fuse members interiorly 1 mounted therein. Electrical for a building usually have a central fuse box located in the basement or in some other part i of the building remote from the occupied quarters, and in the event a fuse blows out, its replacement is more or less inconvenient and is also a difiicult and time-consuming process.
An object of the invention is the provision of a novel electrical appliance suitable both for a plug and for a fuse box whereby a fuse may be replaced without leaving the room in which the equipment is located.
Another object of the invention is the provision of electrical equipment comprising a combination plug and a plurality of fuses wherein the fuses are shiftable in turn to replace those that have been blown out.
Still another object of the invention is the provision of a simple economical fuse and a mounting therefor, by means of which fuses can be easily replaced.
A further object of the invention is the provision of a combination plug and fuse which is sufficiently simple that a novice can manipulate the same and replace a blown out fuse with a minimum expenditure of labor and time.
Still another object of the invention is the production of a combination plug and fuse of the kind described which is simple, compact, durable, reliable, efficient and satisfactory for its intended purpose.
Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the-disclosure herein given.
To this end my invention consists in the novel construction, arrangement and com-- bination of parts herein shown and described,
and more particularly pointed out in the claims.
installations 1931. Serial No. 529,660.
' principles of my invention;
Fig. 2 is a View along the line 22 of Fig.
The sections 11 and 12 may be fastened together by any desired means, and in the drawings they are shown as fastened by interlocking members 13 positioned in sockets 14 and by a spring latch 15 positioned to engage one wall of a recess 16.
An insulated cord 17 provides a conduit. for a pair of conductors 18 and 19 on one end of which the plug 10 is mounted. The other ends of the conductors 18 and 19 may be connected with a lamp or with a radio or with any other device to which electrical energy is to be supplied. The conductors 18 and 19 are connected with binding posts 20 in the usual manner and a pair of terminals 21 and 22 project from the end of the block 10 to provide means for inserting or connecting the plug with a wall socket or the like.
The invention contemplates a combination plug and fuse block so constructed that in case thefuse is blown out it can be quickly such that fuses of any desired strength may Fig. 3 is a sectional view along the line 3-3 there are a corresponding number of fuse members 27 equally spaced about the fuse be employed by increasing or diminishing the CIOSS sectional area of the mid-portion there- 0 The fuse members can be stamped or otherwise formed from sheets of fuse material with a minimum of waste and at a small fraction of the cost of the type of fuses in general use. In replacing the supply of members 27 for the fuse block 25, fuse members all of a givenstrength may be used or, if desired, the block may be loaded with fuse members of different strengths.
The fuse members 27 are shown as located in grooves 28 and the terminal 22 is shown with its inner end projecting through the wall of the housing in spaced apart relation to the corresponding end of the terminal 24. The adjacent exposed ends of the terminals 22 and 24 may be operatively connected by any one of the fuse members 27 mounted on the block 25.
The fuse block 25 and the fuse members 27- may be mounted in the plug in any desired manner but it is found advantageous for some reasons to arrange the block and the fuse members longitudinally of the plug. In the embodiment shown, the fuse block 25 is provided with a hexagonal stem 26 mounted ina corresponding socket in'thehousing memher. The stem 26 may be made octagonal or of anv other equiangular cross-section and be fully as effective as that shown providing block so that in any position of the fuse box there will be a fuse member operatively connecting the exposed adjacent ends of the terminal sections '22 and 24.
If one of the fuse members 27 blows out, all that is necessary to replace it is to remove the plug 10 from its socket, separate the sections 11 and 12 by manipulating the latch member 15 and thenshift the block 25 through the necessary angle-to bring the next adjacent fuse into operative position. It is obvious that the plug maybe used until all of the fuses are blown out and that it is an easy f" matter to replace the old fuse members 27 with a new supply. A transverse groove 29 is formed in the block 25 under each fuse member 27 so that the melted material from the blown out fuses will flow into the grooves and thereby avoid the possibility of a partial connection of the terminal sections 22 and 24 through the melted material.
Thus it will be seen that I have-provided a combination plug and fuse dwice which is sim le, easy to manipulate. economical to .pense."
manu acture and one in which the supply of fuses can be replaced witha very slight ex- Having thusfidescribed my invention, it
is obvious that various immaterial modifications may be 'made in the same without departing from the spirit of my invention;
hence I do not wish to be understoodas limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described, or uses mentioned.
ber, one of said terminals comprising two sections having their adjacent ends arranged in exposed spaced apart relation on the inner periphery of the housing, a cylindrical fuse block positioned on the interior of said housing, said block having a plurality of fuse members on its outer periphery, a mounting for said block providing means permitting the block to be shifted to bring any one of said-fuse members .into cooperative relation with the adjacent ends of said terminals, said fuse members extending longitudinally of said cylindrical fuse block, and said block having .grooves underlying each of said fuse members providing receptacles of substantial depth for the melted material of the burnt out fuses.
2. In an electrical device, a plug, a housing member comprising a pair of sections of insulating material detachably fastened together to form a hollow body, a pair of terminals embedded in the walls of said housing member, one of said terminals comprising two sections having their adjacent ends arranged in exposed spaced apart relation on the inner periphery of the housing, a cylindrical fuse block positioned on the interior of said housing, an axial stem having an equiangular cross section projecting from said block, said housing member having a socket 'in which saidstem is positioned to provide a mounting for the block, a plurality of equally spaced fuse members mounted on the outer periphery of the block, the mounting of said block permitting it to be shifted to bring any one of said fuse members into cooperative relation with the adjacentv end of said terminals.
In witness whereof, I hereunto subscribe my name this 7th day of April A. D., 1931.
