COMBINED SWITCH AND CUT-OUT.
Specification of Letters Patent.
Patented. April 27, 1909.
Application filed December l 1902. Serial No. 133,377.
To all whom it may concern:
' specification.
My invention relates to electric lighting, and especially to series systems oflighting such as are employed upon street cars and similar places Where relatively high tension electric currents are used, and its object is to provide a simple and highly-eiiicient combined switch and cut-out.
My invention will be more readily understood by reference to the accompanying drawing forming a part of this specification. in which- Figure l is a plan of a combined switch and cut-out with the cover removed showing one form of my invention; Fig. 2 is a cross section of the device taken on a plane indicated by line 2-2 of Fig. 1; Fig. 3 is a plan view of the inner side of the coveryand Fig. i is a longitudinal section taken on a plane indicated by line i-e of Fig. 1.
As shown-in the drawing the base A. and
the cover B are of porcelain and form an insulating box for the several electrical parts of the device. The base A. is a plane rectangular slab pierced byv a number of countersunk screw holes and two plane apertures 1 for the passage of the line wires. Upon the upper surface of the base. A and to one side of its center line 1S mounted a snap switch C having a two-arm blade 3. and in. nne with 1 the switch are two stationarycontacts 4 consisting of U-shaped strips of spring metal and connected by screws or rivets to bent arms 5 of the punchedmetal supports (5 and T. The support 6 has its middle portion bent up into a loop 8 and carries a binding screw 9 in an arm 10 extending out. at right angles, and is secured to the base A by two screws 11 extending through the base and engaging threaded holes therein. The support 7 is provided with a loop 12 corresponding to loop 8 of support 6 and a long arm 13 which extends nearly across the base and e ngages afuse contact, and is secured to the base by two screws 14. I
The fuse D may be of the well known cartridge type, provided with metallic caps or end pieces 15 to which the fusible member 15 is attached at its respective ends, and
adapted to make contact with metallic U- shaped clips 16 and 17 of spring metal. The clip 16 is connected to the arm 13 of support 7 by means of an offset 18 from the arm which extends between the arms of the clip and is held in engagement therewith by a screw 19 extending through the base and engaging a-tapped hole in the offset of arm 13. The clip 17 is connected to a metallic strip 20 provided at one end with a binding screw 21, and at the other screw 19.
The cover B has two main cavities 22 and 23 in its underside which are adapted to receive the switch and fuse members respectively and effectually insulate the one from with an otfset 18- and the other by means of tliewall or barrier 24 between the cavities. At each end of the switch cavity 22 is secured a U-shaped clip 25 by means of a screw 26 extending through the cover and engaging a nut 27 located between the arrns of (the clip. When the cover is in place these clips 25 engage the loops 8 and 1201? the switch contact supports 6 and 7, and operate" to hold the cover in place. lthe forward end of the cover is provided with two grooves 28 and 29 through which the line wires may be led to the respective binding screws 9 and 21, when it is-impracticableor inconvenient to lead the wires through the apertures 1 in the base. A hole 30 is provided in the cover for the .assage of the stem of the switch G. T he ower edges of the cover B, with the exception of the grooves 28 and 29 and a slight groove 31 for the passage of the connection 13, are in a plane and make close joints with the upper surfaceof the haseB.
The cover is held in engagement with the base by the clips 25 engaging the loops 8 and 12, and by the thUHlb-plC of the switch, so that when it is desired to remove the cover to inspect or renew any of the electrical parts of the device. it is only necessary to unscrew the thumb-piece and pull upon the cover-to disengage the-clips 25 from the. loops 8 and 12.
litis to be noted that my deviceis adapted to be opened forinspcction without interference with the electrical connections, that when the cover is in place the connections are "substantially sealed against dust. that tween the switch contacts and the fuse con- I tacts, and a cover of insulating material neving two cavities and holding clips adapted to engage said loops.
In Witness whereof I have hereunto set my hand this 2&th day of November, 1902.
