PATENT ARTHUR R. BUSH, OE BOSTON, MASSACHUSETTS, ASSIGNOR TO PAINE & FRANCIS, OF SAME PLACE.
y SWITCH.
SPECIFICATION forming part of Letters Patent No. 425,205, dated April 8, 1890.
Application filed June ll, 1889. Serial No. 313,836. (No model.)
To all whom it may concern.-
Be it known that I, ARTHUR R. BUSH, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Pocket-Switches, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.
This invention has for its object to provide a novel switch, as will be described, especially adapted to be used on incandescent-electric light circuits.
In accordance with my invention, a disk or plate has secured to or forming part of it on one side thereof two arms or projections, preferably of wood or other insulating material, and separated from each other, preferably, a considerable distancef The arms or projections referred to have secured to them contact arms or strips, preferably bent to present an inclined surface, with which co-operates a contact member, herein shown as a metal plate or strip secured to a block, preferably of wood or other insulating material, fastened in suitable manner to a spindle extended through the disk. The spindle referred to extends, as herein shown, through a sleeve secured to orforming part of the disk on its side opposite to that to which'the arms Aor projections are secured, and the said sleeve is provided with a radial hole or opening, through which is extended a bar or rod, preferably made beveled at its end to engage, preferably, a notch inthe spindle (but which may be a projection of any sort, as will be described) and lock the' said spindle against upward or outward movementwhen the said spindie is pressed upon to bring the contact meniber secured to it in contact with the strips or arms to complete the electric circuit. The rod referred to constitutes a retaining` or locking device and is secured to or forms part of a releasing device, herein shown as a yoke to Which is secured a` finger-piece, and by pressing which the retaining device may be disengaged from the notch of the spindle when it is desired to open the circuit. The retaining device-is normally kept pressed against the spindle, preferably by a spiral spring which encircles it. The spindle and its attached contact member are moved upward or outward when disengaged from the retaining device, preferablyby a spring. The disk and the retaining and releasing devices are preferably eoncealed or covered by a suitable cap having a hole, through which the upper end of the spindle projects, and provided with a suitable opening at its side, through which the finger-piece of the releasing device is eX- tended. The disk will preferably be secured to a shell or casing of tin or other suitable material, which is adapted to be inserted into a hole or pocket in the wall of a building or room, so that when in position the switch is covered by the cap, the remaining parts being concealed.
The particular features in which my invention consists will be pointed out in the claims at the en'd of this specification.
Figure l is a vertical section of a switch einbodying my invention; Fig. 2, a top or plan view of the switch shown in Fig. l, with the cap or cover and thumb-nut removed; and Fig. 3, a' modification to be referred to.
The base a, preferably made as ametal disk, has secured to or forming a part of it at one side thereof arms or projections d d2, which may be 'of wood or other suitable material. The arms c a2 have secured io them contact plates or strips c3 ci, having their ends bent, as at d5, to present inclined surfaces with which co-operates a contact member a6, preferably made as a plate or strip, secured, as shown, to a block d'7, of wood or other insulating material, on a spindle d8, extended through the disk d and through a sleeve b, secured to or forming part of said disk. The spindle d8 is provided with a notch b', which is adapted to receive the preferably beveled end of a rod b2, provided, as shown, with screw-threads b3, to engage the threaded opening of a yoke h4, having detachably secured to its opposite end, as by screw-threads, a finger-piece b5. The rod b2 has its outer end inserted into an opening in a lug bs, against which presses one end of a spiral spring UT, encircling the said rod, and having its other end acting against the `yoke h, the said spring normally acting to force the rodh2 forward, so thatits end will engage the notch o ol' the spindle when the latter is depressed to bring the contact; member a in contact. with the contact-arms u* u, l
' with a notch to be engaged by the retaining the said rod hf constituting a ret aining or locking device for the said spindle.
The sleeve b is provided with a longitudinal slot, (see dotted lines, Fig. 1,) into which a rod c, or it might be a projection on the spindle, is adapted to pass when the spindle is depressed.
The spindle c is moved into its outward position when the retaining device is willidrawn from the notch Z1', preferably by a spiral spring c', encircling the sleeve l), one end of the said spring acting against: a shoulder c2 on the said sleeve and the other end againsta washeror ring ci", eneirelin g thesleeve b, and kept pressed against the rod or projection c by the said spring.
The disk in practice will preferably be inserted into a case or shell f7, fitted into a hole or pocket in the wall of the building, and the parts of the switch on the outer face ol' the disk a will be concealed by a suitable cap or cover d', which may be nickel-plated or otherwise ornamented to give a pleasing appearance to the switch and through which the npper end of the spindle a is extended, it being provided outside the cap with a suitable thumb-nut d2. The cap d is provided at one side with a suitable opening, through which the finger-piece lf extends.
It will thus be seen that when the switch is placed in operative position the-parts are concealed within the cap, leaving only the thumbnut di and the finger-piece if accessible to the operator.
The line-wires are secured to the contactarms a3 ai by suitable screws (Z4 di.
As shown in Fig. l. the switch is closed, the circuit being completed, as will be readily understood, through the contact-arms ci; a' and contact member a, and it it is desired to break the circuit the operator presses upon the linger-piece if, which forces the yoke l2 and the rod ZF, attached thereto, in the direction of the arrow 20, thereby withdrawin the end of the said rod from the notch h in the spindle uf, leaving the latter free to be moved upward bythe spiral sprin c', thus rcmovin the member c from eontactwith the arms of* coi.
My improved switch, being designed to be inserted into a hole or pocket in a wall ol` the building, is designated by me as apocketswitch.7
I have herein shown a single-pole switch; but I do not desire to limit my invention in this respect, as a double or other multiple pole switch may be constructed in similar n1anner-as, for instance, two or more independent sets of contact-arms ufl c" may be secured to the projections a a2, and two or more indtmendently (io-operating contact members u. may be secured to the block (.t, all the contact members beingr moved with the spindle di.
I have herein shown the spindle as provided device; but I do not desire to limit myself to this construction, as it is evident the said spindle may be provided with acollar or other projection f, as shown in Fig. 3, with which the retaining device co-operates.
It will be noticed that when the contact member c is withdrawn from engagement with the contact-arms cada1 to open the circuit an air-space exists between each contact-arm ci o," and the contact member c, thus forining a double air-space or break for the switch, thereby making the best possible break in the circuit, and at the same time reducing the are when the circuit is opened.
I claimn l. In a pocket-switch, the combination, with a base provided with projectingarms a n, having contact-pieces (t3 c secured thereto and bent to present inclined surfaces, of a cooperating contact member consisting of a strip o1' plate a, a spindle extended through the said base and to which the contact mem` ber o" is attached, a spring to move said spindle, a retainii'lg device consisting of a rod h2, a spring to move said rod into engagement with said spindle, a yoke secured to said rod and havinga linger-piece, and an independent cap covering said .yoke and rod, and having openings through which the spindle and 1inger-piece are extended, substantially as described.
2. In a pocket-switch, the combination, with a metallic base provided with projecting arms of insulating material and contact-pieces a (tl secured thereto, of a co-operating contact' member consisting of a block ot' insulatingI material and a metal plate secured to said block, a spindle secured to said block and extended through the said base, a spring to move said spindle, a retaining device consisting of a rod Ui, a spring to move said rod into engagement with said spindle, a yoke secured to said rod and havinga finger-piece, and an independent cap covering said yoke and rod, and having open ings through which the spindle and finger-piece are extended, substantially as described. l
f5. In a pocket-switch, the combination, with a case or shell, ol a base provided with arms c o2, extended into said case or shell, and having contact-pieces c c secured thereto and bent te present inclined surfaces, of a co-operating contact member consisting of a strip or plate a", a spindle extended through the said base and to which the contact member c is attached, a spring to move said spindle, a retaining device consisting of a rod b2, a spring to move said rod into engagement with ICO IIO
