SAFETY CUT-OUT.

SPECIFICATION forming part of Letters Patent o. 480,009, dated August 2, 1892. Application filed October 14, 1891. Serial N0.l'98,707 (No model.)

To @ZZ whom t may concern.-

Be it known that I, RUDOLPH FURGANG, Qt Boston, in the county of Suffolk and State f Massachusetts, have invented new and useful Improvements in Safety Attachments for Electrical IVires, of which the following is a specification.

This is a device intended particularly for application to electric-light wires or power- Wires for electric railways, whereby the end of a wire broken accidentally or ,cut intentionally-as by the fire department, forinstance-is automatically and instantly insulated, thereby being renderedperfectly harmless in caseit falls and comes in contact with any object or person, and also whereby a section of wire may be safely removed at will.

In the accompanying drawings, in which similar letters of reference indicate like parts, Figure l is a plan View of my device with the parts in their usual or normalposition, so that the electric current passes freely through it. Fig. 2 is a side elevation of the same. Fig. 3.

, isa central longitudinal vertical'section. Fig. 4 isa view of the side opposite to that shown in Fig. 2, with the parts so arranged that a section of wire may be safely removed. Fig. 5 is a cross vertical section taken 011 line Fig. 4. Fig. 6 is an end' elevation of the de,- vice. Fig. 7 is a cross vertical section on line y, Fig. l.

A is a metallic plate or base made iu two parts, said parts being separated by a central longitudinal opening a, Fig. 3,andconnected by the metallic end plate B, which extends up from the outer end of the plate` and the metallic cross-piece C, Fig. l, which extends from one part of the plate to the other and is preferably integral with both. 'lh'e inner parallel edges of the parts of the'plate A are lined with insulation b, Figs. 3, 5, and.6. Metallic side rails D D are secured to the opposite side outer edges of this plate, and as the plate is cut away at a e', Figs. l and 5, spaces are formed at these points. These side rails extend below the plate and when the device is used in connection with the'pow'er- 4Wire of an electric railway-serve as guards to prevent the trolley fromjumping the wire.

5o These plates are'made in duplicate, as shown,

and are supported centrally by an insulatedy frame E, which extends up from the adjacent ends thereof, said frame being surmounted by a ring or eye E or other suitable device by which the frame may be secured to and the plates sustained by the guard -wire or other convenient means of support.

F F are cylinders lined with insulation, secured centrally and longitudinally to the plates directly over the longitudinal openings 6o a by means of suitable straps F', the rear ends of said cylinders heilig' placed against the end wallsB and the front ends thereof being open. Within these cylinders are spiral springs d, covered with insulation and lying between the rear ends of the' cylinders and shoulders H on the bolts II, Fig. 3. These bolts, which are covered with insulation, have screwed in to them from the rear rods I, which extend through the insulated rearends of the go cylinders and thence through suitable open ings B in the end walls B, Fig; 6, but without coming into contact with said walls, as shown. These rods are provided near their outer ends with vertical holes I', Figs. l and 75 3, and inclines I, leading to said holes. Shafts J have their bearings in the end walls B, and catch-pinsJeXtend ccntrallyfrom said shafts (but being insulated therefrom) and lie normallyin the inc'lines I. Rigidlysecured 8o to the opposite ends of said shafts are the metallic weights K, provided with the contact points K.

,L L are metallic pieces extending from within the spaces d through the side rails D D and insulated therefrom, as shown, and to theseA pieces may be secured ground-wires. The plates A are connected centrally beneath the frame E .by metallic gates N, which are hinged at N to the rails D Dand can be 9o swung up and back at will by means of the insulated handles N".

These gates may be' locked, when closed, by means of the screws N", which extend through the openings n in the gates.

S S are the electric wires, their inner ends being secured to metallic blocks l. The normal position of the apparatus is as shown in Figs. l, 3, and 3. The blocks P are held by the taut electric wires S snugly against the roo small ends of the bolts H, suitable grooves or recesses being provided in the blocks P to preventthem from slipping. The blocks torce vthe bolts H back against the power of the on the wire) or bet-Ween this apparatus and the next point of support for the wire the wir would of course instantly lose its tautness and the bolt H on the side next the break would by means of the spring d throw the block P, with the broken end of the wire, forward, and it would drop out of the apparatus through the open space between the two parts of the apparatus beneath the frame E. Ot course this broken wire, which would thus fall to the ground, would be dead and harmless. Then the bolt H iiies forward ,it carries with it the rod Land the catch-pin J slips by gravity from the incline I and drops into the hole I', thus preventing thebolt from tiying entirely out of the cylinder. At the same time the weights K, which are -fast on the same shaft as the catchpin J', swing down by gravity, aiding the m0- tion of 'the catch-pin and swinging into the spaces a and by means of the contact-pointsK striking and lying against the metallic pieces L, to which the ground-wires are secu red, thus allowing the electricity from' the live wire secured to the other en d of the apparatus to pass through its block Pand the frame A at that end to the gates N, and thence to the frameA at the end of the apparatus nekt the break, and thence through the weights K to vthe pieces L and to the ground-wires secured to said pieces. If a section ot the wire is cut instead ot' being accidentally broken, the effeet is of course the same.

. On one side of each frame A the rail D is cut away to allow of the insertion ot' the me- A talliclatch'R. This latch is hinged at fr to the 'rail D and provided with the insulated handle R and also with the opening R,Fig. 4, which drops over a pin R, secured to the frame A. A contact-piece R serves when the latch is thrown back, as shown in Fig. 4, to make connection with the piece L. On the opposite side of each frame A, next the open end of4 the cylinder F, la portion Af of the frame is hinged to the main portion of the frame at A".

By the,` removal of a screw t, which extends through a slotted locking-piece T, rigidly se"- cured to the surface ofthe swinging portion A', this portion or gate may be swung out vhorizontally, sothat access can readily be had to the block P. VNowin case a section-of 'wire between two of my apparatus is desired' to be removedas in case of a fire, for .instancethe gates N are raised, thus disconnectingthe two parts, of the apparatus, and the latch R between the section desired to be removed and the source of electricity is raised and swung back into contact with Athe piece L, thus conducting the electricity to the groundwire. Then by swinging out the gate A the block P can easily be removed and with it the section of wire connecting it to the next apparatus. The other end of this section of wire is of course removed by similarly operating upon the nearest end of the next apparatus. The space between the two parts of my device-t'. e'., the space under the4 frame E-is so small that atrolley will easily jump it.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

l. In a safety attachment for electrical wires, the plate A, of conductive material and provided with the spaces or openings a', end pieces B, and swinging weights K, held normally up, as described, the ground connections L, the bolt H and spring d within the cylinder F, and the block P, to which the end of the wire is secured, combined and arranged substantially as set forth.

2. In a safety attachment for electrical wires, the plate A, of conductive material, cylinder F, spring d, end piece B, rod I, provided with the perforation I', shaft J, sustained by the said end piece, and catch-pin J', whereby when the spring is released the` bolt is checked in its-outward movement, substantially as described.

3. In a safety attachment for electrical wires, the pair of plates A A, of conductive material, a supporting insulated frame, as E,

conductive. gates, as N, capable ot being opened to destroy the connection, bolts and springs sustained by said plates, and blocks, as P, to which the ends of the electric wire are secured, said blocks being held against lthe bolts by the tension of the wire, whereby ranged, as described, to swing back into con-A tact with the said ground connections, sub' stantially as set forth. 'l

' 5. In an apparatus' of the character described, the combination of the plates A, of conductive` material, bolt H, and spring d,

block P, tov which the end of the wire is secured, and outwardly-swinging gate A,where by access may behad tothe said block, substantially as described.
