ELECTRICAL FITTING.
Specication of Letters Patent.
ratenteauuiy 14, 1914.
l Application led April 4, 1913. Serial No. 758,796.
To all whom it may concern.'
Be it'known that* I, MORRIS F. FINKEL- STEIN, a citizen of the United States, and a resident of the city of New York, borough of the Bronx, in the county and State of New York, have invented a new and lm- .proved Electrical Fitting, of which the following is a full, clear, and exact description. rllhis invention relates to electrical fittings, and has reference more particularly to a device of this class used for connecting the ends of wire or like conductors, and comprising an insulating body, conductor-receiving andy holding means within the body,
means for electrically connecting the conf ductors, and a guard for the last-mentioned means, movable longitudinally of the device, intoan operative and into an inoperative position.
The invention also Arelates to the provision in a device of the class described, of conductor-securing members and a guard normally covering these members and slidable longitudinally of the body of the device to uncover the members. I'llheobject of the invention is to provide 'a simple and efficient electrical fitting, particularly useful as a connector for wire or other conductors, by means of which the ends of the conductors can be securely joined both mechanically and electrically, which permits theconductors to be attached and released easily and expeditiously, which thoroughly insulates the bared ends of the conductors, in which the ends of the conductors and the members for gripping and clamping them are normally guarded and covered, in which the guard can be very readily disposed in operative and inoperative positions, which is compact in form and presents no projections or protuberances, and which can be inexpensively manufactured.
The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claims. Reference is to be had to the accompanying drawings forming a part of this specilication, in which similar characters of reference indicate corresponding parts in all the views,and in which Figure 1 is a perspective View of-an embodiment of my invention.; Fig. 2 is an enlarged, longitudinal section of the device;
Fig. 3 is a similar though fragmentary view, showing the guard in a different position; Fig. l is a perspective view of one section of the body of the device; and Fig. 5 is a transverse section on the line 5--5 of Fig. 2.
Before proceeding to a more detailed eX-V planation of my invention it should be understood that the present form of the device constitutes an improvement upon one of the ittings disclosed in mv co-pending application for Letters Patent of the `United States,
filed November 17, 1911, Serial No. 660,868. Certain of the features of the present device are common to that ofthe application referred to, particularly the means for receiving, gripping and electrically connecting the conductors. The present invention resides mainly in the guard which normally covers the conductor-connecting means; this guard is slidable longitudinally of the device to cover or uncover the set screws which clamp the conductor-'gripping jaws.
Referring more particularly to the draw- -ings 1 provide a fitting the body of which is formed in two sections 10, each of semi-cylindrical form. These elements 10 are fashioned from porcelain or any other suitable insulating material. The fitting has at each end a socket 11 terminating at the inner end in a partition 12 which separates it from a central chamber 13. rllhepartitions have openings 111 therethrough. rlhe chamber 13 is of Substantially rectangular form and receives a correspondingly-shaped sleeve 15, fashioned from suitable material such 'as 'metaL The two semi-cylindrical sections and the body of the device are held-together by end rings 16 of metal, indurated fiber or other material adapted for the purpose.
`Flach end ring has a downwardly directed flange 17 engaging at an end face of the body, so that the rings cannot be moved longitudinally of the body, toward the middle thereof.
Positioned within the sleeve 15 I provide a pair of oppositely disposed spring clips 18 each having serrated jaws 19 adapted to receive the bared end 20 of a conductor 21, the end 20 being inserted through one o f the openings 111 into place between the jaws. rllhe conductor itself enters the socket 11 as is shown in Fig. 2. The sleeve 15, above each of the conductor-receiving clips'has 4a threaded opening 22 in which is received a correspondingly threaded set-screw 23. By
" sisting of a lia-t, elongated member` of less screwing the latter inwardly, the gripping jaws will be clamped together against their' spart longitudinally cut away so that when they are assembled they form a guideway 25, extending the entire length of the body ofthe device and having the ends covered and closed by the rings 16. Slidably mount'- A ed within the guideway is a guard 26 conlength than the length of the guideway. In
the present form of the device theguard is' fashioned from two superposed plates 27 andv 28, the former being the upper and having the extremities downwardly bent-over the ends of the lowerl plate 25. The plates have near one end registerin openings 29 therethrough, and near the ot er end openings 30, y likewise registering. The upper plate about the last-mentioned opening is provided with an annular flange 31 which affords a grip for thelingers in the manipulation of the guard. When the guard is in an operative position it is so disposed that the openings 24 of the body are covered. As is shown in Fig. 3, by sliding the guard as far as it will go to the other end of the body, the openings 29 and 30 register with the openings 24, and thus give access to the screws '23.
Between the two openings 24 the body is provided with a flat projection or stud 32 adapted to engage the opening 30. It will be understood that when the stud engages the opening 30 it tends to hold the guard in position against accidental displacement.` This arrangement thus permits the guard to be held in closed position. The plates will naturally spring aside as the guard is forced from one positlon to the other, and it will not interfere with the desired manipulation. When the guard is in an open position the plates are bowed over the stud` 32 'as is shown in Fig. 3.
It will be noted that the openings 29 and 30 are so proportioned that they are smaller in diameter than the diameter of each of the screws 23. Consequently, when the openings are disposed over the screws, access can be had to these to permit their manipulation lby means of a screw-driver, but should they become accidentally unscrewed they cannot escape through the openings, owing to the smaller size of the latter. The movements of the guard in each` direction are limited by the end flanges 17 of the ring 16.
It will be noted that the threads are car-l' ried down .the side walls, the screws 23 themselves exceeding in diameter the internal width of the sleeve. The purpose of this is to give a better hold to the screw, as the thickness of the top of the sleeve is not adequate for the purpose.
To secure the end rings 16 upon the body sections of the device they are provided with indentations 16";l at which the material is forced into corresponding recesses provided for the purpose in oneof the sections 10.
Having thus described my invention I claim as new and desire to secure by Letters Patent 1-. A device of the class described comprising an insulatin body, a conducting sleeve therein, conductorreceiving and holding clips within said sleeve, screws for controlling said clips, said body having a guideway extending longitudinally thereof, and a guard. movably mounted in said guideway and having openings therethrough, said guard in normal position covering said, screws, said body having end rings partly covering said guideway, said rings having means for limiting the movements of4 said guard.
