ELECTRICAL CUT-OUT.

specification of Letters Patent.

Patented Dec. 6, 1910.

To all whom it may concern:

Be it known that I, JAMES LESLIE BUB- row, a citizen-of the United States, residing at Plainville, in the county of Hartford and State of Connecticut, have invented c'ertain new and useful Improvements in Electrical Cut-Outs, of which the following is a specification. This invention frelates to electrical cut outs the object of the invention being to provide a simple and effective device of this character havmgmeans by which the fuse member can be easily and quickly mounted or dismounted and by which said fuse member can under normal conditions be substantially and solidly held.

The device possesses other features of advantage and' novelty which with the foregoing will be set forth at len 11 in the following descriptio'n where I s all outline in detail that form of embodiment of the invention which I have selected for illustration in the; drawings accompanying and forming part of the present specification. From this itwill be evident that I do not restrict myself to the showing made bv said drawings and description for I may de art therefrom several different ways and stil be within the scope of my invention as expressed in the claims succeeding said description.

Referring to said drawings, Figure 1 is a top plan view of a cut out including my inventlon. 22 of Fig. 1. Fig. 3 is a detail view of the fuse member clip. Fig. 4 is a like view of a supporting clip blank. Fig. 5 is an'edge view of one of the supporting clips.

Like characters refer to like parts throughout the several figures.

The present device as is the case with sev-. eral of those now in existence involves in its make up a foundation, base or back member and the same may he made of any suitable shape and material; a part such as satisfactorily answers my purpose in this connection is that denoted in a general way by 2 and the same may be of porcelain or other suitable'material, and it can be attached to a wall, ceiling or other desirable place in any convenient manner. This part 2 resents a suitable sup ort' for the fuse mem r of the device whici as will hereinafter appear is mounted in a novel manner: The fuse member employed in the present instance is F ig. 2 is a cross section on the line denoted in a general way by 3 and it com- 511565 a body 4 which is shown as of cylinrical form and which is advantageously made of glass although the particular material is not a matter of substance.

The fusible material 5 is inclosed in the glass tube 4 and it may be formed of wire although this is not essential. Where wire, however, is employed its ends are extended through substantially central perforations in the caps 6 closing the ends of the said glass tube, and soldered in place exteriorlyof said caps 6 which as will hereinafter ap pear constitute, respectively, parts of body clips connected with said tube 4. The said glass body preferably rigidly carries at its ends clips such as those each denoted in a general way by 7 said clips extending longitudinally from sald body and one of them being shown in blank form in Fig. 3. This clip 7 can be quickly and inexpensively stamped from sheet metal to secure the blank shown in said Fig. 3 and thegbody of the resultant blank Wlll then be" shaped up to form a tubular shank which is fitted over the open end of the tube the said tubular,shank being then seamed on the glass tube and the same operation following with'its mate at the other end of the said tube 4. In ad dition to this the tubular shanks of the clips 7 can be spun or rolled over .beads 4 near the ends of the tube 4 'whereby there will be no possibility of said clips pulling from place. The said clips 7 have as is obvious outwardly converging resilient branches 8 which constitute in efiect yieldable prolongations of the tube 4 and these branches are adapted 'to fit removably between the branches of supporting clips as will hereinafter more particularly appear.

It is of course a simple matter to shape the blanks of the clips 7 into finished form as indicated in Fig. 1 the bodiesof the blanks being connected with the tube 4 in the manner already described and the formation of the clip bodies naturally producing the outwardly extending yieldable branches 8 to which allusion has been made and these branches 8 will be bent to secure the necessary resiliency. The caps or disks 6 can be bent up after the wire 5 s in place, i the ends of said wire being passed through approximately central erforations in said caps and after the sand ends are passed through said perforations the caps can be pressed firmly and substantially against the open ends of the tube a following which said wires can be soldered in place exteriorly of said caps or disks to secure the finished or complete fuse member, all of the elements of which are positively and securely held together and to such an extent as to prevent their accidental separation from vibration, jars and shocks The supporting clips 9 are mounted upon the back or foundation member 2 and they can be secured in place if desired by screws 10. The supporting clips like the body clips are of integral construction and can be also like the others inexpensively made from sheet metal, the blank of one of the supporting clips being shown in Fig. at. The supporting clips 9 have lateral resilient branches ll bent up or out at practically right angles from the body thereof and while in the present case .the respective branches 11 respectively receive the branches 8, this relation is not essential as it could be reversed within the scope of my invention. The supporting clips substantially and securely hold the fuse member 3 in place by virtue of the construction already described especially under ordinary conditions but there maybe cases where I should prefer not to wholly rely upon the frictional engagement between the respective clips and insuch an event I would prefer to interlock said clips together and I have illustrated and will now describe a means for securing this result.

Upon the outer surfaces of the branches 8 I form projections or teats 12 which are adapted to be sprung into seats or openings 13 in the branches 11 as shown best in Fig. l and the respective projections or teats and seats or openings can be readily formed by the means of a punching tool or other simple pressure means which is used "to slightly press the stock outward to-secure the desired interlocking relations. This interlocking, however, of the resilient branches can be secured in other ways and it will be clear that such a member will have as a relatively permanent part thereof two end clips. These end clips are introduced into the supporting end clips until the sets of clips are interlocked when the fuse member will be solidly held in place although the pull of the hand is sufi'icient to dislod e the same. There is space all around the se member is connected.

so that there is no possibility of dust and other foreign substances collecting therearound. Then there is also a continuous electrical connection between the bod of one end or supporting clip and the ody of the other end or supporting clip and in this case the screws 10 which hold the end clips in position, can be also utilized as binding screws.

hat I claim is It l.- A cut out comprisin a fuse member provided with clips, combined with supporting clips one set of clips being adapted to receive the other set of clips and the respective clips being positively interlocked against accidental movement in all directions.

A cutout comprising a fuse member provided with resilient clips the shanks of which are interlocked with the bodyof the fuse member combined with supporting cli s portions spun over said beads combined with supporting clips one set of clips being adapted 'to removably receive the other set.

4:. A cut out comprising a fuse member having a tubular body, fusible material in said body, and a clip connected to the body said clip having a part closing one end of the tubular body and to which the fusible material is connected.

5. A cut out comprising a fuse member having a tubular body, fusible material in said body, and a clip provided with a tubular shank fitted onto said body and provided with a disk closin an end of the tubular bodv and with which said fusible material 6. A cut out comprising a fuse member having a tubular body, a clip fitted onto said body, and a fuse wire inthe' tubular body,the clip having a part closing an end of the body and perforated to receive said wire. v

7. A cut out ,comprising a fuse member provided with n'esilient clips combined with supporting clips the supporting clips being adaptedto receive the other clips and having seats to interlockably receive projections on-the body clips.
