4 Claims.

The invention relates to an improvement in fuse holders and is particularly adapted for use in connection with small fuses which are of such size that it is inconvenient for the'electrician to i insert or withdraw them from the contacts without danger. i i

It is one of the objects of the invention to provide a simple and economical fuse holderwhich may be readily attached to or removed from the fuse.

, be readily apparent to those skilled in the art when the following description is considered in connection with the accompanying drawing wherein Figs. 1 and 2 show cross section views of one form of the invention wherein the holder is made of a split ring of resilient material and adapted to be clamped about the fuse.

Figs. 3 and 4 are section and side elevation, respectively, of another form of invention wherein the holder is made of a single piece of resilient material.

Figs. 5, 6 and '7 show views of another form of the invention wherein a handle and a spring clip are provided to make up the fuse holder.

Fig. 8 shows a sectional view of another form of the invention which is adapted to be permanently attached to the fuse.

Fig. 9 is a sectional View of one form of the invention which is made of spring like material passed around the fuse and the ends thereof clasped together to form a handle.

Fig. 10 is a side elevation of the invention shown in Fig. 8.

The form of the invention shown in Figs. 1 and 2 illustrates a holder 2 which is made up of a piece of resilient material 3. This material may be cast or moulded as a unitary structure and split along the line 4 so that it may be spread apart as shown in Fig. 1, the split 4 form- 1 ing the

parts

5 and 6 which go to make up the handle 7. It is intended that when the

parts

5 and 6 are separated as shown in Fig. 1 that the fuse 8 may be inserted lengthwise or it may be moved in between the

parts

5 and 6 when they are widely separated. A clip fastener 9 and the Another object of the invention is to devise a,

rEs PATENT OFFICE? clasp 10 therefor have been imbedded in the

parts

6 and 5, respectively, so that after the fuse 8 has been inserted pressure may be-brought to bear upon the parts 5 and;6 to cause engagement of the clasp and socket. Fig. 2 shows the hold er in closed position engaged about the fuse ,8. When the fuse is so held it may beinsertedaor Withdrawn from the electrical circuit as desired. The electrician need merely grasp thehandlefl and need not touch the fuse at any time; The handle 7 extends a sufficient distance outfrom the fuse and from the contacts of the electrical circuit so that there is no danger when the handle is grasped. In the event the fuse is burned out or becomes unserviceable the clasp and socket 9 and 10 may be separated and anew fuse inserted.

It is intended that this form of the invention may be made up of rubber or fiber but preferably of a material which is somewhat resilient to allow insertion of the fuse 8 either longitudinally through the central opening ll or between the

handle parts

5 and 6.

Another form of the invention is shown in Figs. 3 and 4 and comprises an integral piece of resilient material 15. This may be moulded or cast in any manner so that an opening 16 is provided to receive the fuse 8. A sufficient thickness of material at 17 is provided so that the fuse 8 will be frictionally retained and sufficient strength will be provided to allow a pull to be exerted on the handle '7 so that the fuse may be removed from the contacts. It is understood that the fuse 8 is inserted longitudinally through the opening 16 by stretching the material at 1'7 slightly to allow the end members 18 of the fuse to pass there through. The holder shown in this modification may be removed from the fuse after it is unserviceable and placed upon another fuse. It is to be understood that reinforcing material may be imbedded in the moulded material of this modification if desired in order to strengthen the fuse holder and insure that the fuse will not become flanges are arranged to extend substantially halfway around the fuse 8 and one flange is provided with a screw 23 which retains a hinge 24 which is pivoted at 25. This hinge 24 is arranged to pass about the fuse 8 and engage in the groove 26 in the opposite flange 22. In this manner the fuse 8 may be inserted and the hinge 24 moved to clamped position as shown in Fig. 6.

An inturned flange 28 is provided on the hinge 24 and is adapted to engage in the groove 25. Fig. 7 shows a side elevation of this form of the invention.

Fig. 8 shows a sectional view of a form of the invention which embodies a band 30 of springlike material. This material'may be any desired sheet insulation such as horn fibre,.leatheroid or fuller board and is adapted to be bent around the fuse 8 and permanently affixed to the fuse by means of clips or rivets 31. These may take the form of the customary hollow clip which is adapted to be'expanded after it has been inserted through the opening or they may be any suitable type of rivet. It is intended that the band 30 will be of sufiicient strength topermit insertion and withdrawal of the fuse from the contacts in the electrical circuit without actually touching the fuse. Fig. 10sho'ws a side elevation of the inven-. tion illustrated in Fig. 8.

Fig. 9 shows the band 30 illustrated in Fig. 8 as being fastenedtogether by means of

snap fasteners

33 and 34. These fasteners are the same as those usually employed upon gloves or for similar purposes. 1

The present invention is in the nature of an improvement over my prior co-pending application for patent for a Fuse socket and holder, Serial No. 355,645, filed April 16, 1929.

While several modifications of the invention have been disclosed in the drawing and ,specification it is intended that broadly the invention embodies a holder which may be attached to the fuse so that an insulated handle is provided for insertion or withdrawal of the fuse from the electric circuit.

Having described my invention, what I desire to secure by Letters Patent is: I

1. A rubber fuse holder molded in a single piece, a handle portion forming a part of said piece, and a fuse holding portion also forming part of said piece and including an elastic band adapted to have the fuse passed longitudinally therethru and to thereafter hold the fuse due to the inherent resiliency of the rubber.

2. A rubber fuse holder including a solid handle portion, and anelastic fuse holder portion BIO
