PUsH-BUTTon swrrm;
' Application filed December 9,- 19241: "serial i f .3754,851'.
My inventionielates to improvements in push button" switches, and ,in particular to mea'ns'whereby the switch may be locked in a desired position. V H
In certain classes of work such, for -in-' stance, aslinlthe control of motors fordriving printingpresses machine tools and the like, ,it is customaryto provide push button switches for manually 'etfectinga remote v controlfof the driving motors for such equip- 7 mental These switches ordinarily comprise a start push-buttonswitch and astoppush button switch, the energization of the motor beingv initially'effected through the start push button switch' and then maintained through the stop push button switch There are certain-applications 'for which it is desirable. to effect jogging by repeated depressionand release of the start push button 7 and in such cases it-is necessary to hold the stop push button switch in the open position to prevent the maintaining circuit being established unless some special provision is made therefor. The operator is thus com pelled. to=hold the stop button depressed while hemanipulates the start button and this is obj ectionable 7 One of. the objects-of my invention is to provide a-simple; inexpensive and effective arrangement for: rendering it" unnecessary font-he operator. to holdthestop push buttonldepressed. Other objects and purposes of the invention will appear inthe courscof thefollowing -descriptionwhen taken inconnection'with the accompanying drawing in which I have shown the invention embodied in, concrete'form for purposes of 1llustra-' tion. 4
Referring to the drawing-Fig.1 is a plan view 'of my improved switch witha'portion of :the cover. for the switch casing broken" away in'. order .to show the arrangement whereby therstop push button switch is -op-.
erated to and held in, the open position. Fig. 2 is a sectional view-showing the parts of-thecswitch assembly-in their respective,
normalspos'rtionsp Fig. 8 is a similar crosssect-ion-i V16W-- showing. the a parts in their re; speotivepositions when the stop push buttonswitch .is ,held in itsop enapositionw Fig-4 is :a perspective-view of-the-yarious parts'of the: switch.withathe casing and the cover ofs-thei'casingt .removedi:'or thesake. of clearnessaand-Fig. 5 is-a-very simple diagram of a motorcc'ontrol system embodying the push button switch of the invention. Y
Referring to the drawings the various parts of the switch assembly are mounted within'a casing 10 having a cover 11. The various part-sot the start and stop push but ton switches'are mounted as a' unit'on a base 12 of suitable "insulating 1naterial,"the base beingsecuredto thecasi'ng 10 in any suitable manner. This pushbut-tori switch assembly comprises a switch member 13 which cooperates with a corres 'jon'ding con tact 14E andrfor'ms a normally-open starting switch: The push button 15' isprovided for operatingfthe switch in'emberg lifi -the' push button 15 projecting from the cover 11 ofth'e casing and [being connected with the switch member 18. by means of the'post 16; The switch member 17 cooperates with a st'a-' tionary switch contact'18, the'switch memf ber lTbeing' normally biased intoerlgage m'ent with thecontact 18 and forming a normally closed stop switch. The stop' pus h' button '19, is connected with thevswi'tch'me'mber 17 by means of'the post 20 and thi's" stop push button likewise projects tl'ii' oi'igh the cover of the casing 11. The switch'mern bers 18 and'l? are biased so as to be normally'in their respective positions as indicated in Fig, 2, vby fme'ans of the sin l t spring- ,21 which cooperates with a corre sponding end of each switch member, The particular arrangement of a r-push" button switch assembly above'described, is thefirb vention of George S. Leddick, for which-he" obtained Letters Patent of the United States; No; 1,477,884, dated December '18; 1923- j The resilient detent 22' is secured at one end'to the cover 11' for the casingof the switch assembly and the free end otthis detent is arranged to'cooperate with a projection 23 on the'stop pus'lrbutton 19. g This detent is preferably somewhat resilient and; is preferably shapedas shown in the drawings The operating-member 24: for the detent 22-is mounted so' asto be carried by. the cover 11' by the inherent resiliency of the detent 22; in other 'words,the-operating member 24c-is interposed between the detent and the-interiorf surface otthe'cover 11" and" held in that position by. the detent. 9
button of the first switch as in normal operation but that the movable memberis, under these circumstances, returned from its second to its first position upon the release of this push button. e
In accordance with the provisions of the patent statutes, I have described the principle of operation of my invention, together with the apparatus which I now consider to represent the best embodiment thereof, but I desire to have it understood that the apparatus shown is only illustrative and that the invention can becarried out by other means.
\Vhat I claim as new and desire to secure by Letters Patent of the United States,
1. A push button switch having a casing, a movable switch member within the casing, the said switch member being biased to one position, a push button projecting from said casing for operating the switch member to a second position against the bias thereof, a resilient member secured within said casing andarranged to hold said switch member in the second position thereof and normally biased out of cooperative relation therewith, and an operating member for forcing the said resilient member against the bias thereof into holding relation with said switch member, the said operative member being" yieldingly held within the casing by said resilient member and having a portion thereof extending from the casing for operating the same.
2. A push button switch having a casing, a movable switch member within the casing, the said switch member being biased to one position, a push button projecting from said casing for operating the switch member to a second position against the bias thereof, a resilient member having one end thereof secured to said casing and the free end thereof arran ed to hold said switch member in the sald second position thereof and normally biased out of cooperative relation therewith, and an operating member within the casing for forcing the free end of said resilient member against the bias thereof into holding relation with said switch member, the said operating member having a portion thereof projecting from said casing for operating the same.
3. A push button switch having a casing with a removable cover, a movable switch member mounted-within the casing, a push button extending through the said cover and connected with the said switch member, the I of cooperative relation with said switch member, and a reciprocating operating member mounted on said cover within said casing for operating said detent, the said operating member having a portion extending through said cover for reciprocating the operating member to move the said det'ent into and out of cooperative relation with said switch member.
4. A push button switch havlng a casing, a movable switch member within the easing, the said switch member being biased to one position, a push button projecting from said casing for operating the switch member to a second position against the bias thereof, a resilient member within said casing having one end thereof held in posi-' tion and the "free end thereof arranged to Gil hold the switch member in its second position and normally biased out of cooperative relation therewith, the said resilient memher having a portion angularly disposed to the main body thereof, and an operating member within said casing having a s1milar angular-1y disposed portion cooperat ing with the said resilient member with the angularly disposed portions of said members in alignment when the resilient memher is out .of cooperative relation with said switch member, the said operating member being yieldingly held within the casing by said resilient member and having a portion thereof extending from the casing for operating the same, whereby moving the said I extending portion of the operating member in one direction causes the angularly d1s posed portion of said member to move the IOU free end of said resilient member into holding relation with said switch member.
In witness whereof, I have hereunto set my hand this 6th day of December, 1924.
