APPLICATION FILED FEB. 6.' 1914.

PATENT @FFM- GoRnoN noEmiiNG AND EDWARD nnoEniJING, or DETROIT, MICHIGAN.

rusia-BUTTON.

To all t may concern.'

` Be it known that we, GORDON E. ROEDDING 4:@United States of- America, residing atDe- 5iig1&oit,. in the county ofWayne and State of Jfichigan, have invented. certainnew and seful Improvements in Push-Buttons, .of vhich the following is a speciication, ref- ,Ifeenee 4being hadI therein to the accompany ng" drawings.

4provide av push button or compact switch j *wherein positive and reliable means are emtarydevice or separate and distinctappli` vances. v

fAnotherobject of this invention is to provide a push button with a plurality of compactly arranged contacts that may 'be leasily and .quickly actuated to complete a desired electrical icircuit, and itis in this connection, that the -button has been especially designed for installation upon the steering-post of an automobile, whereby the -chafueur or operator of thel machine: mayf readily control various electrical circuits lused throughout vthe machine orin connection with a single accessory thereon.

A further object of this invention is to provide a push button of the above type emjbodying a plurality of strong and: durable parts that are easy to assemble and maintain 'in'operatable condition, and highly efficient as anv electrical switch. ,y

We attain the'above and other` objects by ya mechanical construction that will be hei-einaftpr specifically described vand then claimed, and reference will now be had to the drawing, wherein,l l j Figure l is a plan of thepush button with the cover or cap thereof removed;"Fig. 2. is 'a si'inilar view of the push button with the co'verfor cap in place; Fig. 3 is a cross sectonalwiew of the push button, and Fig. 4 is a view similar to Fig. 1, illustrating the electrical connections ofthe device. lIn the drawings 1 denotes a base plate that' isp'referably circular in plan View and.

secured to said'basevplate screws 2 or `otherfastening means, 1s a circular plateor disk 3 'made of insulating material, as ioer nd EDWARD B. RonDDiNc, citizensA of the ...This invention'relates to push buttons, and y fthe-primary object of our invention is to.`

'or'rubberp The top .of the plate 3 has a ,926,1 i Specification of Letters Patent. i Patented Apr; 13, 1915. u Application ledebrnary 6, 1914.' Serial 110,816,916. I

an annular wall or holder 5 'that is preferably made integral with the circular plate 3.

Mounted in the holder 5 are diametrically opposed binding posts 6, 7 8 and 9, preferably inthe form of screws, and adjacent to each, binding post is a slit or slot 10 approXimately half the depth of the holder. The

slits yor slotsy `10 accommodate the outer ends Vof tangentially disposed

resilient contact arms

11, 12, 13, and 14, that extend inwardly to a. point in proximity to the verti` cal aXis of the device. The inner ends ofthe' arms 11 to 14 4inclusive are contiguous` to the inner ends ofthe binding posts or screws 6 to 9r inclusive and constitute contact members adapted to complete electrical circuits when-brought into contact with the inner ends ofthe binding posts. The outer ends yof the contact arms are bent against the outer side ofthe contact holder 5 and secured thereto by screws -15 o r other fastening means, serving as binding posts, as `will hereinafter appear. M

rPhe contact holder 5, adjacent to the binding post 9, has the wall thereof cut away, as at 16 andsecured to said holder in proximity to the plate 3 and within the cut away portion of the holder is a flat Contact member 17, which extends inwardly to af point centrally of the recess 4 and is provided with avertical pin 18,fas best shown in Fig. 3. The Contact member .17 is held in position by a binding post or screw 19 and adjacent to the binding post 19 is another binding post or screu7 20 employed for holding a spiral resilient contact member 21 above and out of contact with the pin 18. The spiral contact member 21 is of the ordinary and well known type used in connection with a push button and is adapted to be depressed -to engage the pin 18 and establish anielectrical circuit independent of the contact arms 12 to 14 and central circular recess 4 having for its d-ls` over the slots 23. is a socket member orslide button 24 having a concentric sleeve 25 exrtendin through the slots 23 into the casing forme by the base plate 1 and the cover 22. .The sleeve 25 is exteriorly screw threaded and screwed thereon is a retaining plate 26 and an insulating member 27 made of liber or rubber. The member 27 is circular in plan view and the sides or periphery there of is engaged by the contact arms 11 to la inclusive, as best shown in Fig. 3.

Movable longitudinally of the sleeve 25 is the .push rod or shank 28 of a push button 29 located Within the socket of the member or slide button 24. Encircling the rod or shank`28, between the button 29 and the bottom of the slide button 24 is a. coiled compression spring 30 that retains the push button 29 normally elevated or in a -pro jected position. The inner end of the push rod or shank 28 is provided With a contact head 3l adapted to engage the central portion or inner convolution of the spiral contact member 21 and shift said member into engagement with the pin 18 of the member 17 to complete an electrical circuit, in a manner similar to an ordinary push button. 'Ihe space within the casing, between the contact holder 5 and the walls of the cover 22 provides suliicie'nt clearance for leadingin Wires which enter the casing through a sleeve 32 carried by the base plate 1 andan opening 33 formed in the circular plate 3.

As illustratedin Fig. 4, a leading-in Wire 34 is connected to the binding post 9 and by branches, to the binding

post

19, 8, 7 and 6. A leading-out wire is connected to the binding post of the contact arm 14, and in a

like manner wires

36, 3S and 39 are connected to the binding posts Iof the

arms

13, 12 and 11, respectively. Another wire 37 is connected to the binding post 20 of the member 21. These leading-out Wires may be assembled in a cable extending through the sleeve and the opening 233, and then the proper connections established. v As an example of means for attaching the push button tofits support, there is illus itrated in Fig. 3, a t\vopart clamp employed for connecting the push button to a steering post of a steering wheel therefor. One part 40 of the clamp is preferably formed integral with the base plate l and the detachable part 41 of said clamp is connected to the part 4() by set screws l2 or other fastening means.

The slide button 2l constitutes means upon the casing of apush button for shifting one of the contact arms 11 to 14 inclusive into engagement with one f the binding posts G to 9 inclusive, as the slide button 2l is guided by the slots 23 in the proper radial directions tocdefiect the arms int'o contact with their posts. The resil ncy ofthe severalcontact arms operates to yieldinglyhold the button in an axial position relative to the casing and to return it to that position when moved therefrom as Well as to break the circuits when the button is released.

As an instance of the operation of the butt-on, We will assume that the button 2,4 is shifted to the right. The member 27 then contacts with the resilient arm 13 and said varm is shifted into engagement with the completing the following binding post 7 circuit from the leading end wire 34 through the binding post 7, arm 13 and screw 15 to the leading out wire 36. With these Wires in circuit with a suitable source the plate 26 to prevent dirt, Water, etc.,

from getting into the casing and interfering with the operation of the electrical contacts.

It is thought that the opera-tion and utilityv of the push button will be apparent without further description, and While in the drawing there is illustrated a preferred embodiment of the invention, it is to be understood that the structural elements are susceptible to such'variations and modifications as fall within the scope of the appended claims.
