CUT-OUTn SPECIFICATION formingpart of Letters Patent No. 766,490, dated. August 2, 1904.

To all whoml it my concern:

Be it known that I, FERDINAND BUoHnor, a citizen of the United States, residing at the i city of NewYork, inthe borough of Brooklyn l description.

This invent-ion relates to electric cut-,outs`r l the object being` to providea simple and eompaci structure operated by a push-button or plunger and especially adapted for insertion in or combination with an incandesceutdainp socket, the cut-out being' used bv me in suoli a location for the purpose of controllingv a tapcircnlt taken from the main circuit ol the socket; but it will be understood that the improved cutout may be used under various conditionsand that the invention resides iu the construction itself and not in any special combination with other devices or apparatus. .My im provci'l cut-out con ipi'ises,essi`:ntially,

a lixed plate. opposite and parallel to which is arranged arotary disk carrying on the surface i opposed to the plate a pair of contacts adapted when the disk is in one position to make contact with said p lute and whenin another posia g tion to straddle said plate without making' cong tact therewith. The disk provided with a series of ratchet-teetli` and inunedialelv adioinl ing these and in a parallel relation is a fiat plat-e actingr as a plunger by manual manipulation, said flat plate having' two dogs, one of which 1 is adapted to engage one of the ratchet-leeth i of the disk during the forward movement of the plunger, while. the other dog engages another of the ratchet-teeth during' the return movement of the plunger. gagements cause the disk to be. rotated each 40 acne-eighth turn, so that a movement of the g plunger inward and outward rotates thedisk i a, quarter-turn and either completes or breaks l the circuit between the disk and tixed plate. Auxiliary to these devices is a spring' comv bined and arranged in such manner as to keep the plunger to its work and ,vet permit g it to yield to avoid interferiuiee with theI E ratchet-teeth during rotary motion of the disk.

The parte of my cut-out are housed within a block of hard rubber or other suitable inrifhis bioeh made in two part-s r and il. each beingsubstantially a disk having' a diamctrical raised portion across one face, thus leaving' a srgnncntai opene Fig'. i [sun edge view Fig. 8 is a the joining' of the two disks. held together by bolts u". one on each side ot' 'flfhe disks are ln the disk if there is an axial metal stud Z1, having' attached to its j uteren=1l a contact head and at its' inner end. a crosrelni-ad 12in the lorni ol" a plate, each rnd of v. hielt tor-shaped and olI .slightly less than ninetyde- This plate is a fixture in noir# cular depression .'f and leaves open sectorshaped spar/es /f' at\' pp sile sides. lfiiis plate /fis a circuit terminal or contact through whirh the current mai be ied to the head 1)' and to an extension Ji'- l'oi anydesired arrange ln the disk u." there is a contact-head c, exposed outside, which is attached to the end of an axial screw c', around the head of which lits a rotaia` disk f, which stands parallel to the fixed plate and concentric with the stud lf. The upper surface of this disk c is provided at diainetrically'opposite points with two lugs i" if, shaped similar to ratchet-teeth,

'lhese teeth are adapted to make cont-act siuuiitancously with the opposite `Aends oi' the plate when the dish is rotated to bringl this connect-ion about; but when the disk is rotated ninety degrees from the position of contact the lugs project engage the ratchet-teeth e2 on the disk.

into the spaces b b", and thus break* the eircuit. The under side of disk e is provided with' four ratchet-teeth e2, arranged in a circle at the outer edge of the disk and all pointing in the same direction. Immediately beneath the disk is a fiat plate f, serving as an operating-plunger, said plate having a slot j", through which the screw c passes, and having two dogs f 2 and f3, extending upward on each side of the slot and in a postiorjr1 ttio C plate f extends radially outward through an opening in the side oi' the block A and carries at its outer end a push-button f. A spring g is provided between the head of the pushbutton and the block A, having a tendency to force the button outward. Beneath the plate fis a disk upon the stud e', which disk is forced against platef by a springj, surrounding the stud c' for the purpose of holding plate f up against disk so that its dogs f s and f3 will engage with the ratchet-teeth. At the same time the disk is free to tip in any direction, thus permitting the plate f to yield when the ratchet-teeth of the disk e ride over the dogs of the plate, as will be hereinafter described. It will be seen that when diskeand plate 712 are in contact a circuit is closed from Contact c through the stud c', disk e, plate b2, from which it branches, one branch leading through the stud to the button b and the other through the extension b5.

The operation is as follows: Referring more. particularly to Figs. 4 and 5, it will be seen that the plunger f is extended outward in Fig. 4. 'Ihis is the normal position, during which the circuit may lbe either open or closed. We

will assume that at the present time the lugs e' of disk e are.I occupying the spaces b, the circuit being thus open. By pressing the push-button f* and forcing the plunger inu ward the dog f engages with a ratchet-tooth e2 and the disk is rotated one-eighth of a turn, during which motion a ratchet-tooth e2 on the opposite side of the disk slides over the dog f3 and assumes the position shown in Fig. 5, where the dog will engage with its shoulder upon 4the return movement of the plunger. The plunger now being released, spring g acts` and forces it (outward, during which movement dog f3 aforesaid Aengages with ratchet-tooth e2 and moves the disk another one-eighth turn in the same direction as before. This completes a quarter-turn of the disk and carries the two lugs e', respectively, into contact with the ends of the plate and closes the circuit. it will be seen that dur- I plate in one direction.

ing the movement of the disk to carry the yield or tip. This is permitted by the yielding support beneath the plate; It will ybe seen that the to-and-fro excursion of the plunger completes either a make or vbreak of the circuit.

It is obvious that this structure may be used'also for a double-pole switch by insulating the lugs e' from each other and insulating the ends of the plate b2 from each. My invention is therefore not limited in respect to the number of circuits or lines controlled.

Having described my invention, I claim-- 1. In an electric cnt-out, the combination with a fixed plate forming one terminal of the circuit, a rotary plate arranged parallel thereto and adapted to make and breakI contact therewith, in combination with-a' plunger 2. In a cut-out, the combination of a fixed.

contact-plate, a rotary disk carrying contactpoints adapted to engage and discngage with the plate, ratchet-teeth arranged in a concent'ric'crcle on said disk and a reciprocatory plunger provided with two dogs adapted to engagerespectively and alternately with ratchet- (tieelh o n opposite sides of the center of the v3. In a cut-eut, the combination of a fixed contact-plate, a rotary disk carrying contactpoints adapted to engage and disengage with the plate, ratchet-,teeth'arranged in a concentric circle on said disk, a reciprocatory plunger provided with two dogs adapted to engage respectively and alternately with ratchet-teeth 'on opposite sides of the center of the disk and aspring tending to hold the plunger in engagement with the ratchet-teeth.

4. The combination of the fixed contactplate b2, the rotary contact-'disk e' having ratchet-teeth, a reciprocatory plate provided with a slot through which the axis of the disk passes, two dogs carried by said plate adapted to engage the ratchet-.teeth alternately and a spring adapted to move the reciprocatory In witness whereof` I subscribe my signature in presence 'of two witnesses.
