FUSE CABINET Filed Jan. l2, 1927 INENTOR.
ATTORNEY.
Patented Oct. 29, 1929 UNITED STTS Peur oFFicE FUSE CABINET Application led January 12, 1927. Serial No. 160,751.
The present invention relates to fusing de vices and especially to such devices for heavy fuses, and it has among its objects means in which the fuses when conducting current are entirely insulated and therefore cannot be touched accidentally.
Another object is a device of the character indicated which can be used as a safe form of switch witho t removal of the fuses.
1o Other objec s will readily appear to those skilled in the art upon reference tothe following description and drawings, in which Fig. 1 is a front elevation of a cabinet involving the invention and adapted for two fuses;A
Fig. 2 is a vertical section on line 2-2 of Fig. 1;
Fig. 3 is a cross section on line 3-3 of Fig. 1;
Fig. 4 is a section on line 4 4 of Fig. 1; and
Fig. 5 is a section like that of Fig. 4 but with the fuse block reversed.
In the drawings there is indicated at 10 a metal cabinet provided with a flanged cover 11 having a depressed central portion 12 cut out at its central part and forming a mask for that part of the interior of the cabinet surrounding the fuse block (to be described in detail) and forming a chamber or compartment 13. Over the depressed portion 12 may be hinged a door 14 as shown in Fig. 1.
The fuse block consists of a rectangular cup or cup-shaped socket of insulating material 2O having at each end an extension or foot 21 and one or more openings 22 to the inside of the cup immediately above the foot 21. Also, at each end inside the cup is a vert-ical rib or part of a dividing wall 23.
The current carrying wires 29 are led into the cabinet 10 through suitable openings and secured to contact members 30 on top of the feet 21, as shown in Fig. 2, which members 30 extend through openings 22 to the interior of cup 20 at the ends thereof and are of spring material and divided as shown in this ligure so that a co-operating finger or blade may be inserted between them. It is preferred to protect the members 30 against accidental contact with the ends of the fuses by securing in block 2O strips 20? of insulating lmaterial extending up in front of the members 30A as indicated in Fig. 2. A I' i Co-operating with cup v 20 is a block 35 adapted to lit into the cup. ,This .block is recf tangular in its upper4 portion and isprovided with a rib 36-co-operating with :the lower 'por tions of ribs 23 to divide.thelo-vverI part of the cup interior into f two ,'compa rtmentsA The I block at each end has vertical g'roovescofoperl ating with ribs 23- and .therebyzguidinglthe block during insertion. i
The underside oftheblock on each fside'of rib 36 is provided with fus/eholdingclips' 37 to which are attachedthe L- shaped fconta.ct 65 blades 38 extending some/what; ibeyond .the clips and ldownwardly so'` as to lbe 'adapted to be inserted between ,thetwopart-.s of.v inembers 30 indicated in,Fig.f2,
In this reversed position. of course, no current can Iiow through leads 29 and the device may therefore be used as a switch. so
In order to facilitate the removal of the block 35 a small bail or handle 35i is provided, which bail is preferably hinged so that it will be flat when not being used.
It is also preferred to make the block and cabinet of such relative proportions that the door of the latter in closing will push the part 35 into its fina-l position if this has not already been done by the operator. Y
While the cabinet has been described as adapted for two fuses, it is of course obvious that it may be adapted for any number of fuses and such adaptation is contemplated.
It is also contemplated to provide blocks 35 with fuse clips for different sizes of fuses so that the same cabinet may be used for systems designed for different currents, or the fuse clips may be omitted and conducting strips used. In this case the device becomes simply a switch.
'[he device constructed as described provides a neat and compact instrumentality in which the live conductors are completely covered when the block 35 is in place and which provides efficiently against accidental contact with the live terminals When the block is out as such terminals are located within the socket pprtion and completely surrounded by insulating material.
Having now described the invention and the preferred form of embodiment thereof, it is to be understood that the said invention is not to be limited to the specific details herein set forth but only by the scope of the claims which follow.
1 clam- 1.- .In a filsng device, a Cup-Shaped Socket of inslating material having ribs on oppo site walls, contact members in the bottom of said socket on QppOsite sides of said ribs, a fuse block of insulating material having a thereon with fuse holding and contact marie 0.11' @its er 'Side thereef, seid fuse block adapted ho into said socket and make contactbetween said means and members with" said ribs alinement whereby to form a dividing Wall between said fuses and contacts.
2- In 'a'fung device e @11p-Shaped Socket of insulatinglfnaterial Having Contact members therein connected t0. Suitable Condutors, means in said socket to lprevent accidental Contact with said members and a block of insulating material oarryinf 4fuses on one side thereof ada ted to fit ino .said Socketand connect sai Contact members through the fuses, said'block also adapted to fit into said socket in reversed position and thereby cover said Contact members and separate the fuses from said contact members.
