SWITCH-BUTTON.

Original application filed October 24, 19Q7,'Serial Serial No.

To all whom it may concern:

Be it known thatl, GHARLEs A. CLARK, a citizen of the United States, and a resident of Hartford, in the county of Hartford and State ofConnecticut, (whose est-office aid dress is 62 Maple avenue, I" artford, Connecticut) haveinvented certain new and useful Improvements in Switch-Buttons, of which the iollowin is a full, clear, and exact art may make and use the to buttons for The invention relates automatic adjustment.

Theobjects of the-invention are to provide the button of the spindle thereof.

A further object is to. induce a button parts so ar range that therew-illbe practically no liability of relative rotation between the button and said arts. v I 1 A still urther object is to provide an adjustable button havin -are'sihent cushion of extreme simplicity and onewhich is not lia ble to lose its effective tension in use.

Referring to the drawings: Figurel is a view illustrating a button ap lied to a rotary snap switch and with parts roken away in section to better illustrate the constructibn. Fig. 2 is an enlarged side view illustrating .the retainer and its several appurtenant parts. Fig. 3 is a section view taken on the line of Fig. 2.

The button hereinafter'described is par ticularly designed for an used in connection with switches and may be a plied either to'a rotary snap switch such as illustrated or to what is commonly known as a flush spindlejfor actuating the switch mechanism which extends through, or adjacent to' an which incloses or covers the Working parts. The button is screwed or otherwise seoured to the spindle and is used for rotating same.

It has been found desirable and necessary to.providesome'*means appurtenant to the i Specification of Letters Patent.

No. 398,887. Divided and this application filed February 15, 153113.

' button for permitting a close fit oi said but ton with reference to the face plateor cover Without liability oi undue cramping.

It is the primary object of the present in vention, to provide a button having a re. silient cushion interposed between the buii-- ton and its means for attachment to the spindle. it is also intended to arrange the resilient cushion in such form that it will maintain its spring action and will not be liable to lose its resiliency.

In the accompanying drawings the nu meral 1 denotes the button applied to the s indle' 2 which, as shown herein extends t rough the cover 3 of the snap switch i. The switch forms no part of the invention and its details have not therefore been illustrated, although it is to be understood that the spindle 2 upon rotation of the button 1 actuates the switch mechanism.

The button l is composed of any desirable material, preferably one, which may be molded, vulcanized, or otherwise employed to surround and hold a suitable retainer 5.

This retainer 5 is substantially cylindrical in form and is provided witha header 6, opened. sides 7 and 8, and side frame members 9 and 10. The side frame members 9 and 10 nor mally extend below button 1 and are arranged to pass through and be bent over a Washer 1 l. This washer ll is notched on opposite sides, andthe ends 12 and 13 are passed through the notches and then bent inward over the plate or washer 1 l. The retainer 5 is arranged to be secured in the body or the button in any desired mam nor as by lnoldinig it therein or otherwise curing it, and forms a suitable recess for the spring cushion and appurtenant parts.

Nithin the recess of the retainer there is located a spring plug 14, which has, at its inner end a head 15, corri'isponding in ge11-- eral form to the inner walls of the retainer. I

The body part of the spring plug is pref erably of angular cross section and upon it are arranger: a series of leaves 17, having pen iorations corresponding 1n shape to the body the lower end. 10 of the r its lower end by which part of the spring plug 14. I As shown herein these spring leaves are arranged in pairs with their curvature opposed to each other, so that each pair of leaves thus arranged fbrm a 'ng' member of substantially elliptical sen the opposed spring leaves, hearing ates 18 are interposed between them and is the two semi-elliptical leaves bear upon pcsite sides of the bearing plates 18. It

' i has be seen that the springcushion bethe header and the washer 11 .is

c, it is apparent that the interhearing plates 18 may or may not desired. ring the spring leaves and the spring angular form, there is little or no possihcity of any of the parts rotating rela- 20 tively to each other and as thev are all held \Jitllifi an inclosed retainer, tiere is pliac Rally no opportunity for the parts crampon herein described is similar A application. The articular v H} herein shown and descrl ed being n. To secure'greater ease of action be v "p of a series of elliptical springs, and

n forming the subject mattermatter divided from said coending a plication. Ser. No. 398,887, file Oct. 24, 1907.

What I claim as my invention and desire to secure by Letters Patent is:

1. A switch button having a recess, a spring plug located therein, curved spring leaves arranged in pairs and with their curvatures opposed and means for retaining said s ring leaves Within the recess.

2.1 switch button having a recess, a spring plug located therein, curved spring leaves arranged in pairs and with their curvatures opposed, bearing plates intermediate the said opposed spring leaves, and means for retaining saidzleaves and bearing plates within the recess. I I

3. A switch button having a recess, a

spring plug located therein, a Iplurality of spring members of substantialy elliptical' fennarranged upon said spring plug and means for retaining said spring members within the recess.
