UNITED STATES PATENT OFFICE.

CARL H. BISSELL, or SYRACUSE, NEW YORK, ASSIGNOR To cRoUsR-nINns COMPANY, or SYRACUSE, NEW YORK, a CORPORATION OF NEW YORK.

COMBINED FUSE AND SWITCH' BLOCK.

Application filed Aprifl 30, 1920. Serial No. 377,950.

To all whom it may concern:

Be it known that I, CARL H. BissnLL, a

citizen of the United States, and a resident of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Combined Fuse and Switch Block, of which the following is a specification.

This invention has for its object a combined fuse block and switch which permits a particularly simple efficient and compact arrangement of the fuses and switch mechanism, and also a simple and compact arrangement of the handles and fastening means by which the block is placed and secured in. a box as the box connected in an electrical conduit system which box or the opening through which the block is placeable and removable is of the same shape and slightly greater in size or areathan the fuse block.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure 1 is a plan view, partly broken of this combined fuse block and switch.

Figure 2 is a plan view of the base block, the fuse contacts, switch mechanism, and cover for the switch being removed.

Figure 3 is a sectional view on line 33, Fig. 2, the switch cap being included.

Figure 4 is an inverted plan view of the base block.

Figure 5 is an inverted plan View of the cover for the switch base.

This combined fuse block and switch comprises a base block of insulation having a substantially plain or fiat face on one end portion or half thereof, an integral switch base rising from the other end portion thereof, fuse contacts on said face, switch mechanism in the switch base including wire terminals and terminals connected to one set of fuse contacts, and a' cover for the switch.

1 designates the base block which is usually formed of porcelain and is rectangular or oblong in form. 2 is the face on which. the sets of fuse contacts 3, 4 are mounted. 5 is the switch base which is circular or of such shape that it recedes at 6 and 7 respectively from the side edges of the block toward the central part and one end of the block, leaving spaces at 8 and 9 respectively for handles and for fastening members by which the block can be placed into aboX or cover opening in one side of the box of the same shape and but slightly larger than the area of the block.

The device, here illustrated, is adapted for a'three wire system and is provided with contacts for three fuses mounted on the face 2 and the pairs of contacts for the respective fuses are separated by barriers 1O integral with the block and extending lengthwise of the face 2 from the switch base 5, said barriers having cutouts 11 between their ends for facilitating handling of the cartridge fuses when being inserted and removed. Said contacts are secured in position in any suit able manner as by

screws

12, 13 extending through the block from the rear side thereof through

holes

14, 15, the screws 1 also extending through wire terminals 16 connected to the contacts 3.

The switch mechanism may be of any suitable form, size and construction, it being of any standard. form ofsnap switch. Said mechanism includes wire terminals 17, 18, 19, located at different elevations on the base and having switch contacts associated therewith, terminals 20, 21, and 22 for connection .with one set of fuse contacts a, and having switch contacts paired with those of'the wire terminals 17, 18, 19, switch arms 23, 2 1, 25 for connecting and disconnecting the

terminals

17, and 20, 18 and 21, 19 and 22, and a rotary operating member or stem 26 extending through the top of the cover 27 for the switch base.

The base 5 and cover 27 are formed with suitable cutouts 28 28 by which the line Wires can pass to the terminals l7, 18, 19.

The cover is secured in position in any suitable manner as by diametrically located screws one of these screws being shown and designated 29 and the hole for the other screw being shown. The terminals 20, 21, 22, are connected to the fuse contacts i by conductors or wires located in grooves 30 in the bottom side of the block, said wires extending through hollow screws 31 to binding screws on the terminals 20, 21, 22. Said screws extend through the base from the rear side thereof and are located in holes 32.

The handles by which the block can be tening screws. By reason of the location of the screw holes the screws can be driven and removed through the cover opening which, as before stated, is of nearly the same size as the base block. 7

An additional screw hole 36 is provided substantially central of the face 2. It is apparent that by reason of the relative arrangement of the fuse supporting surface 2, the switch 5, the handles or cutouts 33, and the

holes

35, 36 for the fastening screws, the device can be readily mounted in a confined space.

This fuse block and switch is especially adapted to be used in a box such as shown in my pending application Sr. No. 111,688, filed July 27, 1916 which has become Patent No. 1,350,486, granted August 24, 1920, and the stem 26 or operating member is provided with a coupling section as a cross pin 37 arranged to coact with a complemental section on the stem of a rotary handle provided on the cover of the box.

that I claim is:

-1. A combined fuse block and switch comprising a rectangular base having a substantial fiat face on one end portion thereof, and a circular switch base rising from the other end portion thereof, the base block being formed with recesses in the opposite margins thereof located at points where the switch base recedes away from the edge of the base block toward the central portion of the block, substantially as and for the purpose described.

2. A combined fuse block and switch comprising a rectangular base having a sub stantially flat face on one end portion thereof and a circular switch base rising from the other end portion thereof, the base block being formed with recesses in the opposite margins thereof located at points where the switch base recedes away from the edge of the base block toward the central portion of the block, and with holes for receiving fastening members located at the corners of the base block adjacent the switch base at points Where the switch baserecedes from the side edges of the base block toward the end edge thereof, substantially as and for the purpose specified.

3. A combined fuse block and switch comprising a rectangular base having a substantially flat face on one end portion thereof and a circular switch base rising from the other end portion thereof the base block being formed with recesses in the 0pposite margins thereof located at points where the switch base recedes away from the edge of the base block toward the central portion of the block, and with holes for receivlng fastening members located at the corners of the base block adjacent the switch base at points where the switch base recedes from the side edges of the base block toward the end edge thereof, the base block being also formed with an opening for a fastening member located in the central portion of said flat face, substantially as and for the purpose set forth.

.4. A combined fuse block and switch comprising a rectangular base having a substantially flat face on one end portion thereof, a circular switch base rising from the other end portion thereof, and barriers running lengthwise of said face from the switch base, finger receiving recesses in side 1nargins of said base block located at points where the switch base recedes from the side edges of the block toward the central part thereof, holes for fastening members located in the corners of the block adjacent the switch base where it recedes from the side edges toward the end edge of the block, and an additional hole for a fastening member located in the central partof said face, substantially as and for the purpose set forth.

In testimony whereof, I have hereunto signed my name, at Syracuse, in the county of Onondaga and State of New York, this 30th day of March, 1920.

CARL H. BISSELL.
