UNITED STATES PATENT OFFICE.
RAYMOND C. FISHER, OF ROCHESTER, NEW YORK, ASSIGNOR TO NORTH EAST ELEC- TRIO COMPANY, OF ROCHESTER, NEW YORK, A CORPORATION- OF NEW YORK.
' GROUND CONN EGTION Application filed January"25, 1923, Serial No. 614,884. Renewed October 16,1925. A
In an electrical apparatus provided with a metallic frame or casing and with an insulated binding-post, it is often desirable to rovide a connection or ground between the I hiding-post and the casing; and this is commonly done by means of a conductive bond or strap secured, at one end, to the binding-post, the other end of the strap being secured to the casing.
The objectof the present invention isto "provide a ground-connection, for the purpose just set forth, which shall be simple,ef-
fective, and neat in appearance. To this end I..use a cup-shaped conductor which is s mounted upon and concentric with the hinding-post and which spans the insulation of a the post, and makes conductiv'econtact' with the casing at its annularmar in.
, A preferred embodiment o theinvention 29 is illustrated in the accompanying drawings,
' in which Fig. 1 is a sectional elevation of a ground connection, and Fig. 2 is a bottom view of the same;
The invention is illustrated as used in con i nection with a binding- 0st 3 which is embedded in and supporte by a body 4 of insulating material. The body 4: is supported on a metal plate 5 which may constitute a part of the casing of an electrical apparatus The binding-post has the-usual threaded exwasher 9 maybe used to tremity, to which wires or terminals may be secured by nuts.
The novel grounding-device is in the form of a cup 6 drawn from sheet-metal and perforated centrally to receive the threaded 8e portion of the binding-post. This cup is preferably bent outwardly at its free margin 7 and at this point it engages the surface of the plate 5. When a nut 8 is screwed home onthe binding-post it presses the cup firmly against the plate, and a spring lockprevent accidental loosening of theparts.
It will be apparent that this grounding- -device may be very easily applied and that it requires no parts for securing it in 0perative position, other than thoseprovided for the ordinary use ofthe binding-post.
The invention claimed is:
jecting through, but insulated from, a conductive body and provided with screwthreaded fastening means, of a groundingdevice in the form of a metal cup, centrally perforated'to receive said fastening-means, the free edgeof the cup being. pressed into engagement with the surface of said conductive body, around the binding-post.-
