IAN I. WALBERG NEDRA, OF IRWIN, PENNSYLVANIA, ASSIGNOR TO PENN ELECTRICAL AND MANUFACTURING COMPANY, OF IRWIN, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.
FUSE CLIP AND RETAINER.
Application filed November 25, 1921. Serial No. 517,729.
To all whom it may concern:
Be it known that I, IAN I. WALBERG NEDRA, a citizen of the United States, and a resident of Irwin, in the county of Westmoreland and the State of Pennsylvania, have made a new and useful Invention in Fuse Clips and Retainers, of which the following is a specification.
This invention relates to fuse clips and similar retaining devices and an object thereof is to provide an efiicient clip of simple construction for fuses of the ferrule contact type or similarly mounted devices.
A further object is to provide a single piece clip having a stop at one end which serves not only as a stop, but as additional tension means for the gripping portions or ears of the clip.
These, as well as other objects I attain by means of the clip described in the specification and illustrated in the drawings accompanying and forming a part of this application.
In the drawings, Figure 1 is a view in side elevation of two clips and a fuse assembled in position on a mounting member. Fig. 2 is an end view of the assembly. Fig. 3 is av side view in elevation of a single clip embodying this invention. Fig. 4: is an end view of the same and Fig. 5 is an end view similar to Fig. 4, but in this view, a fuse is shown being inserted within the clip and the view by means of dotted lines graphically illustrates the functioning of the clip and the bridging spring.
The clip is formed from a single piece of suitable strip metal, such as copper or bronze of the desired width and is bent to form a base portion 6 with upstanding grippin portions or ears 77. The strip extending longitudinally in opposite directions from the center is slotted or slit off from the main portion and the separated portion is bent up between the gripping portions as shown in Figs. 2, l and 5, so as to form a stop 8 which functions not only as a stop but as a bridging spring between the gripping portions 7-7, and, on account of its form, increases'the gripping power of the ears The base is preferably punched to provide a hole 9 to receive a screw or other fastening means.
In Fig. 1, two clips are shown mounted upon an insulating piece 10 and the ends of the terminals or leads 11 and 12 are drilled and tapped to receive screws 13. A fuse 14 is shown in place within the clips. In Fig. 5, the deflection of the gripping ears to receive the fuse or other device is illustrated in full lines and the normal position of the gripping cars is shown by dotted lines. The fuse itself in normal position is also shown by dotted lines.
The spring ears 77 are bent forwardly as shown at 15-15 so as to form a saddle for the fuse.
The bridging spring, by prolonging the effective spring life of the clip, increases the eflicient life thereof and ensures proper electrical contact, thus minimizing the chance of heating due to poor contact.
Having thus described my invention, what I claim is 1. A spring cli formed from a single strip of metal an comprising a base, upstanding gripping ears' and a bridging spring connecting said gripping ears.
2. A fuse clip according to claim 1, in
which the top of the bridging spring extends at least to the center of a fuse when in clipped position.
3. A spring clip according to claim 1, in which the gripping ears form a saddle for the fuse and the bridging spring is constructed to form afuse stop.
In testimony whereof, I have hereunto subscribed my name this 21st day of November, 1921.
IAN I, WALBERG NEDRA.
