SNAP SWITCH. LPI'LIGATION mum slam. 20, 1907. RENEWED JULY 30, 1910.

rams that '-I, qGr ninilns J KLEIN; the United t-at'es, and resident of tjgt of New York,'--inzthe county of New and State of N egw York, have in- .Snap-Switches, of which the following is rinciples. of my invention. 1 he,'struetureshown in the drawing has merely been 'selected to show the nature of invention, and therefore it should be nstrued in- :anillustrative and not in a mitiii'gsensexj' "fl he'pri'nciples of my invention may be embodied in'difi'erentformsand applied to if switches and other devices of various types.
niimbers are as follows I*,"-1:gure" 1 1s a side elevatlon of a switch qvltf-ltthe supporting frame shown n section.

I xproyi'dea cam member 1, whichin the presusiiti instance two oppositely inclined .i ortions 2* and 3 in the form of a double onical ffr istuim The" ends. of 'the cam member 1 are preferably formed as butonsiiwhichimay"protrude through the sides he" frame or casing in which, this cam beif'inay be mounted. The cam memy'befyfmoved'from left-to right, and ($1 1. in 'endsor buttons.

The helical spring has its heliees engaging the cam faces and "h ie slid'ing" member against the cam, can age-movement of said member in 'a peculiar manner which will be explained hereinafter. The helical spring 4 sTATns w. gigar-swrrcn.

"5 by means of a pin, into which are fastened the ends of the spring, said pin. passing through said sliding member. Of course, the spring may be connected to the sliding member in any other suitable way.
The sliding member carries upwardly extending contacts. which contacts are adapted to engage the stationary contacts 6 mounted upon the frame 7 The switch contacts may assume any suitable form and may be associated with the sliding member in any suitable manner so. as to be actuated thereby. y
I shall now describe the operation of the structure shown in the drawing. \Viththe parts standing in the position shown in Fig. 1 the switch is closed. If the button be pushed so as to move the cam 1 to the left, the spring 4 will engage the left side wall of the frame 7, the cam faces 3 will pass through and extend thespring 4.
When the inclined surface 2 comes into' engagement with the spring 4 and'the sliding member 5, the spring, on account of its resilient engagement with said face,- will slide over said face 2 and also cause said sliding member to slide over said face toward the left. thereby quickly imparting a. bodily movement to the sliding member 5. The sliding member will also partake of apiv otal movement upon being shifted from engagement With the 'faceB into engagement These movements will shift the bodily and angular position of'the sliding member, and the contacts carried therebyinto the position indicated by dotted lines,'thereby separating said contacts from the stationary contacts 6 and thus 'opening the switch. In order to close/the switch the left hand button maybepush'ed to movethe cam member lfto the right-{thereby causing the spring 4: to engage the opposite side wall of the frame 7 so that the cam face 2 will pass through said spring 4 until said spring and the sliding member the taper face 3 of th'e'cam, which will cause the sliding member 5Iand the contacts to partake of bodily and angu'larinovement in the opposite direction, thereby throwing .fsaid'contacts into engagement with stationary contacts 6 again: It will beevident that various changes may be made in the structure whlch I have o reengage.
illustrated and described herein,'without in any'way departing from the principles of my invention. 4
What I claim is:
1. The combination of acam, means for moving said cam, a spring'engaging the face of said cam, a member connected to said spring and cooperating with the face of the cam and means for producing a relative movement between the cam and the spring,
thereby causing a bodily and angular move ment of said movable member.
2. The combination of a cam having two portions inclined with relation to each other, a spring directly engaging said cam, a mem- ,ber engaging said cam and connected to said spring and means for producing a relative movement between cam and spring whereby a bodily and angular movement of said member is produced at an accelerated speed.
' 3. The combination of a cam, a spring directly engaging said cam, a member connected to said spring and engaging said cam and means for reciprocating said cam, thereby causing said member to partake of a bodily and angular movement at an accelerated speed in eitherof two directions.
t. In combination, a cam member having an inclined face, a sliding member having abase adapted to engage said face, and a resilient member engaging said face and connected to said sliding member to cause said sliding member to move.
5. In combination, a cam member having an inclined face. a sliding member adapted therewith, a helical spring connecting with.
said sliding member and engaging said cam member, and a switch contact associated withsaid sliding member and actuated thereby. l
8. In an electric switch, in combination, a cam having oppositely inclined faces, a switch member engaging said cam, a helical. spring engaging said cam and connected to said switch member.
In a switch mechanism, in combination,
a frame, a movable cam member in the form bodilv movement at an accelerated of a double conical frustum, a switch member engaging said cam member, a helical spring surrounding the cam member and connected with'said switch member.
10. A mechanical movement comprising a cam member having oppositely inclined faces, a sliding member engagin therewith, a resilient member engaging sai cam member and serving to hold said sliding member upon said cam member, said sliding member being moved 'pivotally and bodily by a (:0- action between said three members, said cam member being moved to shift one .of said in clined faces from engagement with said sliding member and said resilient member and bring the other face into engagement therewith.
11. In an electric snap switch, the com bination of a cam having oppositely inclined faces, a spring engaging said cam, a switch member engaging said cam member. and connected to said spring and means for moving said cam, the parts being so constructed and arranged that the switch member is given an angular and bodilym0vement at an accelerated speed independent of. the means for moving the cam. y
'19.. In .an electric snap switch, the cqmbi nation of a reciprocating camhaving oppof sitely inclined faces, a frame supporting and guiding said cam, a push button carriedby said cam and projecting through the side of the frame, a coiled spring engaging said cam, a switch member cooperating with said cam and connected to said spring, the parts being so constructed and arranged that the switch member is given an angular and speed in;
dependent of the cam.
13. In an electric snap switch, the combi nation of a reciprocating cam, push buttons] 7 mounted at opposite ends of the cam, said; cam having oppositely inclined faces, afframe for supporting and guiding said push buttons and cam through which framethe 10-5 push buttons project, a switch member.engaging said cam member, a coiled sprlng-s'e'fl cured to said switch member, said s" f. likewise engaging said earn, the parts 1' so constructed and arranged that the switc 'member is. given an angular and bodily movement at an accelerated speed. inde pendently of the cam. p f
