UNITED. STATES PATENT OFFICE.
WILLIAM WURDAOK, OF ST. LOUIS, MISSOURI.
COMBINATION SOCKET-SEATING AND FUSE-TESTING BLOQK.
Application filed December 31, 1923. Serial No. 683,653.
erally constructed is more or less inconvenient and involves tl'ie'expendlture of considerable time, work, and labor; and it is the chief object of my present invention to provide means in the form of a combination socket seating and fuse testing block so constructed that the blown fuse of the panelboard may be located quickly and with facility and convenience.
With the above and other objects in View, my present invention resides in the novel features of form, construction, arrangement, and combination of parts hereinafter described and pointed out in the claims.
In the accompanying drawing,
Figure 1 is a fragmental plan view of a panel-board equipped with combination socket seating and fuse-testing blocks embodying my invention;
Figure 2 is a perspective view. of one of the blocks illustrated in connection with a fuse-testing device;
Figure 3 is a fragmental inverted plan view of one of. the blocks; 7
Figure 4 is a vertical sectional view of one of the blocks; and
Figure 5 is a plan view of one of the blocks.
Referring now more in detail and by reference characters to the drawing, which illustrates a preferred embodiment of my invention, A indicates the block proper, which is of hard rubber, porcelain, or other insulation and of suitable height and dimensions, having preferably the form and shape best seen in Figure 2.
Formed in the block A and opening upon its one or upper end, is a pair of spaced circular recesses or pockets 1, 1, and disposed centrally at the base of each pocket 1 is an insulation boss or lug 2 integral with block A. Seated in each pocket or recess 1, is a cup-shaped socket-member 3 of copper or other suitable conducting material, the annular or side wall of which is suitably threaded, and the end wall of which is apertured to accommodate the insulation boss 2, as shown, the sockets 3 being adapted to receive and accommodate fuse-plugs 4 of standard form and construction. As so seated, it will be seen that the sockets 3 are embraced, and the outer faces of their walls concealed, by the block A.
Having its head 5 disposed upon the boss 2 and forming the end or center contact of the respective socket 3, and extending longitudinally through the block Avto the lower end thereof, is a preferably threaded pin' or bolt 6 adapted for electrical connection upon the lower end of the block A with the terminal 7 of a conductor 8, as best seen in Figures 3 and 4.
Having engagement with the end wall of each socket 3 and threaded longitudinally through the block A also to the lower end thereof, is a pairof suitably elongated screws 9, 9, for detachably fastening the respective sockets 3 to their seats and also, in turn, adapted for threaded electrical connection with the legs 10, 10, of a yoke-shaped terminal 11 having a laterally extending stem 12 adapted for electrical connection with the terminals 13 of conductors 14.
Preferably, as best seen in Figure 3, the
block A is suitably cut-away or recessed upon its lower end, as at 15, 16, for seating the terminals 7 and 1], respectively.
At and adjacent its upper end, the block A is integrally formed with a pair of spaced lateral enlargqnents 17, 17 and formed obliquely in each enlargement 17 to 0 en at its one end upon the upper face of t e enlargement and at its other end in the pockets 1, are ways or grooves 18, 18, for accommodating the terminals 19, 19, of a circuit-testing device 20,0f standard form, the same, as is usual, including a lamp or other signaling member 21 for visually or otherwise indicating the electrical condition of the electrical device being tested.
' In use and operation, a plurality of the blocks A are sultably disposed and mounted in the desired electrical arrangement and connection with the conducting bus-bars, not shown, u on a panel-board B and the sockets 3 thereo in turn, connected in circuit by .means of the conductors 8 and 14 with the various translating devices,- also not shown, the system being electrically protected by the several fuse-plugs 4 seated in the sockets 3. Heretofore, as stated, in the employment of panel-boards of the type here generally described, considerable difficulty, inconvenience,
and consumption of time have been experienced in locating a blown fuse-plug. With my invention, however, the enlargements 17 and their ways or grooves 18 permit convenient electrical engagement through or in the blocks A of the terminals 19 of the cir cuit-testing device 20 with the concealed walls of the several pairs -of sockets 3, the then completion or non-completion of the test circuit depending upon the condition electrically of the plugs 4 seated in the tested sockets and their electrical condition being at once indicated by energization or non-energization of the signal 21. Thus, in a simple, but most efficient manner, my invcntion enables the locating quickly, without requiring the removal of the seated fuseplugs 4, of the blown fuse-plug of the panel, whereby consumption of time, work, and labor and the consequent cost and expense thereof are greatly obviated.
I .am aware that changes in the form, construction, arrangement, and combination of the several parts of 'my new combination socket seating and test-blocks may be made and substituted for those herein shown and described without departing from the nature and principle of my invention.
Having thus described my invention, what I claim and desire to secure by Letters Patent 1s:
1. In a combined socket-seating and fusetesting device, an insulation block formed with a pair of spaced pockets, sockets seated in, and having their walls embraced by, the pockets, andterminalmembers engaging the sockets and the block for including the sockets in an electrical circuit, the block having normally 0 en ways both opening at an end upon a sur ace of the block and leading at their opposite ends intb the respective the upper pockets for freely removably accommodat- 1n the projection of circuit-testin termina s through the block and into direct engagement with the walls of the respective sockets.
2. In a combined socket-seating and fusetesting device, an insulation block formed with a pair of spaced pockets, sockets seated in, and having their walls embraced by, the pockets, and terminal-members enga the sockets and the block for including the sockets in an electrical circuit, the block being obliquely rovided with normally open ways both 0 ening at their u per ends upon ace of the bloc and leading at their lower ends into the respective pockets for freely removably accommodating the projection of circuit-testing terminals through the block and into direct engagement with the walls of the respective sockets.
3. In a combined socket-seating and fusetesting device, an insulation block formed with a pair of spaced pockets, sockets seated in, and having their walls embraced by, the pockets, terminal-members engaging the sockets and the block for including the sockets in an electrical circuit, and lateral enlargements integral with the block and each provided with an obliquely downwardly disposed normally open way opening at their upper ends upon the upper aces of the enlargements and leadin at their lower ends into the respective poc ets for freely removably accommodating the projection of circuit-testing terminals through the block and into direct en agement with the walls of the respective soc ets.
In testimony whereof, I have signed my name to this specification. I
WILLIAM WURDAGK.
