Specification of Letters Patent.
ELECTRIC swirrcn.
Patented Oct. 11, 1910.
State of Connecticut, have invented certainncw and useful llmprovements in Electric Switches, of which the'fol'lowing is a speci- -l ig. a is a detail showing the fication. Y
The object of the invention is to produce. a compact and durable switch easy to manu'-.
facture by introducing certain new features of construction. 7
In the draw1ngsF1gure 1 is a side view of the switch'mechanism with one pair of poles removed in order to show construc tion. Fig. 2 is a bottom view'of the complete switch. Fig. 3 is a detail side view of one of the hub-plates of the pole pieces. le-plate. Fig. 5 is a side view of the same. ig. 6. are front and edge views of the hub with the locking pin and lug. Fig. 7 is an edge view of the frame. Fig. 8 is a side View thereof. Fig. 9 is a side View of the escape-plate. Fig. 10 is an edge view thereof.
Referring to the drawings a is the frame formed as shown to substantial U-shape, the lower edge of each side being cut away to form shoulders at a by which the throw of the poles is limited. Z2 is the spindle supported in the frame; a e are the poles mounted on the spindle; 0 is a U-shaped poleplate each side of which lies next to one of the poles and is secured thereto by downturned cars 0 in one side of the pole-plate there is a slot 0 cl is an escape-plate having a locking-flange d; e e the push-buttons connected with the escape-plate and by means ofwhich the escape-plate is moved; f a hub pivoted 'on the frame having two radial arms f f on one of which there is a locking-pin 7 which coiiperates with the slot 0 in the polewplate, there being a downturnedlug f on the other arm cooperating with the locking-flange d on the escape plate. A projection 01 on the escape-plate underlies the connecting bar 0 of the pole-plate and a spring s is coiled on the spindle with its ends projecting on either side of the projection 01 and bar 0 A pin or on the frame rides in a slot d in the escape-plate, limiting the extent of its oscillation. c
The operation is as follows: As seen in 1 the lug f rides on the outer side of turns tothe'left, the lockingflange'df riding under'thelug f At the same time the projection 0Z carries one end of the'spring "the locking-flange d. As the left-hand push-button ,is pressed in the escape-plate around the spindle, the other end being held against movement for the reason that itrests against the opposite side of the bar 0? on the pole-plate which is connected with the poles, this pole-plate being held against movement during this initial movement of the pushbuttons and escape-plate by reason of the fact that the pin f is in engagementwith the slot 0? in the pole-plate and the hub is kept from turning by reason of the engagement of the lug f with the locking-flange d. As soon as the locking-flange passes completely from under the lug f the poles and connected parts are free to turn and they are thrown with a quick sharp action by the spring until the bar of the pole-plate strikes against one of the shoulders a.
It is to be noted that the point of engagement of the locking-pin with the pole-plate is inside of the point of engagement of the lug with the locking-flange and that the locking-fiange moves through an arc of a circle which is to one side of the median line through the center of the hub and spindle while the locking-pin travels the are of a circle which cuts this median line.
By this arrangement and construction of the parts a very compact switch is produced, yetone having a long break, very eflicient in its action and very strong in its construction.
I claim as my invention 1. In an electric switch, a frame, a spindle, a pole-plate,'poles secured thereto, an escapepl'ate, push-buttons connected with the escape-plate, a locking-flange on said escapeplate, a hub,radial armsextcnding therefrom, a pin on one arm in engagement with c an escape-plate mounted to oscillate on the spindle, push-buttons Connected therewith, a hub .pivotally mounted on the frame movable independently of said escape plate, intercn gaging'parts on said hub and said pole-plains.
interlocking parts on said hiib and said escape-plate, the point of engagement of the former being inside of thepomt of engage mentof the latter, and a s rin connecting the escape-plate with the po e-p ate, substam tially 'as described.
stopping shoulders, poles secured to said pole-plate, an escape plate mounted to oscillate on the s indle, push-buttons connected therewith, a ng on said esca e-plate underlying the cross-bar on sai pole-plate; a spring .wound about the spindle with its ends located on opposite sides of said projection and cross-bar and connecting sald 'escapelocking-flange on the escapeillange,
plate with said pole-dplate, said pole-plate having a slot in one e e thereof a hub .pivotall mounted on the me, radial arms extending from said hub, a on one of said arms ndingin the slot'in said pole-plate, a lateya lug on the other arm coiiperating wit said lockmgthe path ofmovement of said pm crossing the median line connecting said spindle and hub, the path of movement of said lug being "wholly to one side thereof, substantially as described and for the pur- 30 poses, set forth. 1
