C. D. BOTTOMLEY ELECTRIC SWITCH Filed July 8, 1921 T o all whom it may concern new'and useful Improvements in anElectric.
Patented Sept. 18, 1923.
ELECTRIC SWITCH.
Application filed July 8,
Be it known that I, CLARENCE Liar a citizen of the United States, residing at Charlotte, in the county of Eaton and State of Michigan, have invented certain Switchyand I do hereby declare the following to be a full, clear, and exact description off the invention, such as willenable others skilled in the artto whichit .appertains T to make and use the same.
This invention relates to closing means for electric circuits whereby a single push button whenpressed upon closes the circuit against the tension of a spring, the circuit closing elements being retained in "closed position by locking means, the latter being antomatically released when the button is next pressedupon whereby the circuit is broken. This alternate pressing inward of the push button effects a closing and a breaking of the circuit.
Other objects parent and suggest themselves as the nature of the invention is understood.
While the drawing illustrates ancmbodiment ofthe invention it isto be understood that in adapting the sameto meet different conditions and requirements, various changes in the form, proportion and minor details of construction'may be resorted to without departing from the nature of the invention.
Referring to; the accompanying drawing .1 forming "a part; of the specification.
' Figure 1 is a vertical central sectionof a push'button switch embodying the invention showing the parts in normal position. Figure 2 is a view similar to Figure 1 with the button depressed and. the contact elements locked in closedapositionp Figure *3 is a view similar to ,Figure 1 showing the relation of -the parts when the button has been depressed a second time to release the circuit closing element.
Figure 1 is a top plan view of the switch, the cover and the button being removed.
Figure 5 is a front view of the parts illustrated in Figure 4, and
Figure 6 is a detail View.
Corresponding and like parts are referred to in the following description and designated in the several views of the drawing by like reference characters.
The switch comprises a base 1, a cover 2 and a push button 3. The base 1 may be of an insulating material such as compressed D. BOTTOM-- and. advantages willbe ap- CLARENCE D. BOTTOMLEY;
or CHARLOTTE, MICHIGAN.
,1921. Serial No. 483,254.
paper, vulcanite or the like. The cover '2- 1s of dome shape and 15 adapted to be sc-.
cured to the base 1 in any preferred way. The block 4 is provided centrally upon the upper or outer side of the base 1 and pivotally supports a member. 5 which is normally pressedoutwardly at its free end by meansv secured to the base 1 at opposite sides of the pivoted member 5 and are adapted to engage the curved ends of the contact 8 when the pivoted member 5 is pressed inward. The terminals of the electric circuit are adapted to be connected with the contact 9 in the usual way.. l
lVhen the free end of the pivoted member 5 is pressed inward and the electric circuit closed by the contacts 8 and 9 engagine the circuit is maintained in closed position-by locking-means which in thepresent instance consists of a spring catch 10 secured to the base 1 and extending through a cut away portion of thepivoted member 5 forwardly of the cross bar 7 The spring catch 10 has an inner shoulder 11 which is adapted to en- I gage over the-cross bar 7 and hold the free end of thezmember .5 pressed inward- An outer shoulder 12 of the spring catch 10 is adapted to engage over the forward portion base 1 in any convenient and substantial way.
Thebutton .3 is mountedin a boss of the cover 2 and is free to move in and out but is held from rotating by a pin and slot connection. The pin 13 is carried by the button 3 and the slot 1 1- is formed in a side of the boss of the cover 2 in which the button 3 is mounted. The outer end of the slot 14 is closed to limit the outward movement of the button. An expansible helical spring 15 normally exerts a pressure to hold the button 3 pressed outwardly. The spring 15 is mounted upon an extension 16 of the button which forms a guide therefor. The inner end of the spring 15 is seated in an opening formed in the block 1. A tr p 17 is pivoted within a groove 18 formed in aside of the button 3 and its free endis formed with a shoulder 19 and a bevel 20. A spring 21 normally exerts a lateral pres sure on the trip 17 to move its free end outwardly to coact with the spring catch 10 and the pivoted member 5. The spring 21 is seated in a recess formed in a side of the button 3.
When the parts comprising the switch are properly assembled they appear substantially as illustrated in Figure 1 when in normal'position. To close the switch the-button 3'isfpressed inward as indicated in Fig ure 2: The extremity-of the'trip 17 engages the cross bar 7 of the'pivoted member 5 and V when the'butto'nfi is pressed inward to the limit of its'movement the crossbar 7 clears the inner shoulder 11 of the catch l0, and
the latter swings inward to cause the' shoul-T der'll 'to-fengage over the cross bar and lock the pivoted member 5 and holdthe p switch in closed position, This is indicated most clearly in Figure 2;
inward a second time. This causes the beveled end 20 to ride upon the spring catch 10 and disengage theshoul'der 11 thereof from the pivoted member 5, the shoulder 19 of thetrip '17 engages-a second shoulder 12 ofthe catch 10 thereby limitingthe inward movement ofthe button 3 and holding the catch 10 clear of the pivoted member so-that upon releasing the button 3 both it and the pivotedmember 5 'move outward, thereby breaking; the circuit by the separation of the contacts 8 and 9. This operation isindicated most clearlyin'Figure 3 which'illus- "trates the button 3' at the limitof its inward movement and the catch 10 clear of the pivotedimember 5. The inward mov'ement'of the'bu'tton 8'upon :therelease stroke is less than the inward movement to effect closing of 5 theswitcli this being due to the engagement 1 of the shoulder 19 with the shoulder 21.
Having thus described the invention, what I claim is:-
1. An electric circuit closer'of the char acter specified, comprising a relatively fixed Upon releasing the button 3 the same moves outward under the actionof the spring 15; To break the circuit itis necessary to move the button 3' cooperating contact, a catch havingfa lateral' shoulder to engage the movable member, a' push button, anda movable trip car r V ried by the push button and havingashoulder to engage the shoulder of the catch.
3. An QlGCtIIC CIICHItjClOSGf-Of the-jchan acter specified, comprising {a relativelyfixed a cooperating contact, "a catch having opposed shoulders. at different. points in its lengtl1,:a push button, and a mOVabIe-trip carried'by the push-button and adaptedto engage catchf a. An electric'circui't closer of the char act'erspecificd.comprisingfixed contacts, a
pivoted member, a contact 'carried by the pivoted member andelectrically insulated therefrom and adapted to "cooperate; with the fixedcontac't, a spring catch extending:
through the pivoted member andfhaving tinner and outer shoulders, a push-button, and a pivoteditrip carriedjby the push button and having a: shoulder at its inner end.
5. A circuit closer comprising a. spaced fixed contact thereon, apivoted member, a cooperating contact carried by'the pivoted member and electrically insulatediftherei from-,a cover, a push button mounted in the cover and held from turning "and a trip pivoted to the push-button and adapted to "contact, a movable member provided'wit'h' and coact with the shoulders of the v eii'e'ct release o-fjthe pivoted member at each alternate button.- c
