SHELL-HOLDER FOR ELECTRIC CUT-OUTS.

To all whom t may concern Be it known that I, GEORGE HEIEMAN, a

-citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Shell-Holder for Electric Cut-Outs, of which the following is a specification.

. My invention consists of a holder` for the shell of an electric cut out, the same being.

of novel, simple, and inexpensive construction as willbe hereinafter set forth.

It consists also of a novel holder of the character stated, the same comprising an open frame, a neck7 and an eye formed from a plateof suitable material in which said eye and neck are punched out of the portion of said plate of which said open frame is constructed, thus effecting a vast saving of material and consequent eXpense.`

The invention is satisfactorily illustrated in the accompanying drawing, but the important instrumentalities thereof may be varied, and so it is to be understood that the invention is ynot limited to the specific details shown and described, as long asthey are within the spirit or scope of the claims.

Figure 1 represents a perspective view of a shell holder -for an electric cut outembodying my invention.

Fig. 2 represent-s a longitudinal section.

thereof on line 2--2, Fig. 1.

Fig. 3 represents a top or plan view of the holder and shell.

Fig. 4 represents a'central section of the device and its connections on an enlarged scale. A y

Fig. 5 represents a perspectivevlew of the shell.` v p Fig. 6 represents a central section thereof. Fig. 7 represents a plan view showing the method of producing the holders.

Similar numerals of reference indicate.

corresponding parts in the drawings.

Referring to the drawings 1 designates the porcelain base of anl electric cut-out, and 2 designates a shell which occupies the tubular portion thereof, and is adapted to receive a fuse-plug usual in such cases.

3 designates the holder for said shell, the same consisting of the open frame 4', the neck 5 extending from a side thereof, and

a head with anope'n'ing therein forming,

the eye 6, said head being on the outer terminal of said neck.

On the periphery of said eye are the Specication of Letters Patent.

turned-up lips 7 which are spaced apart and deslgned as guards to receive between them an electric wire or conductor and prevent shifting of the same from said eye, the opening lin the latter being adapted to receive the screw 8, which by means of the washer 9 serves to connect' said wire or conductor with said eye.

' In the side of the shell 2 is the throat 10 which forms 'a passage for the insertion of the frame 4 of the holder 3 into said shell, said frame when so inserted being adapted to rest on the bottom fiange 11 of Isaid shell. A screw 12 is passed through the washer. 13 which rests on the top of the frame 4 of the holder 3, and also through said frame, and the bottom wall of the base 1, its threaded end engaging the threaded sleeve or nut 14 in said base whereby said frame may be connected with said bottom wall of the base 1, and the shell 2 retained irmlywithin the This is asgagement with the adjacent portion of the base 1, as shown at the left side of Fig. 4.

In the manufacture of the holder 3, I take a plate of suitable metal 'and punch out of t'he same the contour of the eye 6, the lips 7 "and the neck`5, and I cut the plate across `from the inner terminal of said neck right and left on the lines 15 to the side edges of the plate thus producing the contour of the open frame 4, it being noticed that said neck, eyeand lips are removed from the adjacent portion of the plate that comprises said open frame, thus effecting a vast saving of material and consequent reduction of expense in the manufacture of the holder, it being noticed that the opening in said frame admits the` securing screw 12 passing through the same into' the base, while also reducing the weight of the frame portion of the holder and admitting of sufiicient surface of the latter to be supported flat on the flange 11y of the shell.

The lips as punched out as in Fig. 7 are subsequently turned up at an angle to the periphery of the eye as shown in Fig. 1, and the other figures. f

It will be' seen that a portion of a side of the frame punched or cut out forms the opening 16 in said side and' the material removed therefrom comprises the neck of thev i adjacent holder, and s o there 1s a utilization of a portion of the material of which said open frame is formed A to produce said neck and eye of an adjacent holder which is a vast saving of material in the manufacture of the holders in that the neck f and eye of one holder are made within the confines of the open frame of the adjacent holder.

The plate of the eye 6 is coincident in size with the opening in the framefl, and the lips 7 of the head are coincident in size with the recesses 17 in the wall of said opening. The neck 5 is coincident in size with the opening 1B. Consequently, in cutting or punching out the eye-head, the lips 7 are formed therewith.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is z- 1. The combination of a shell having a bottom flange and athroat inV its side, with an open frame having a neck, said frame and neck resting upon said flange with an eye eX- tended through said throat and having bendable fianges, fastening means passing through said eye, securing means passed through said bottom of the shell, and means beneath the bottom of the shell for retaining said securing means.

2. The combination of a shell having a bottom flange and a throat in its side, with an open frame having a neck, said frame and neck resting upon said flange with an eye extended through said throat and having bendable flanges, fastening means passing through said eye, a washer resting upon the open frame, securing means passed through the bottom of the shell, and means below the bottom of the latter for retaining said securing means, said shell having in its side a throat forming a passage for the insertion of said open frame.

GEORGE HEINEMAN.
