To all whom it may concern:
Be it known thatI, LAURENT A. Fao- BERGER, a citizen of the United States, residing at Lynn, in the county of Essex, State of Massachusetts,have inventedcertam new 7 and useful Im rovements in Controller Finers, of whic the following is a specication.
My invention relates to contact fingers for electric circuitcontrollers and has for its object the provision of an improved device of this character which will be of a rugged construction and at the same time sim 1e and cheap tomanufacture. Devices of t is character, coinmonly known as controller fingers, are liable to be subjected to hard usage and the construction must, therefore, be of the most'rugged character. As often constructed a contact button of copper is riveted at its center to a contact spring. This construction doesnot, however, prevent the button from getting loose and turnin on its riveted center. One of the objects of my invention is to produce an arrangement in *which such turning will be prevented even thou h the. button should become loose, and whic is constructed of punchings which may be easily assembled.
Other objects and purposes of my invention will appear in the course of the following description in which I have disclosed my invention in one form for purposes of illustration.
In the accompanying drawings illustrating my invention, Fig.1 is a perspective view of an assembled controller finger embodying my invention; and Fig. 2 is a perspective view of the separated parts.
Referring to the drawing, 10 indicates the contact button which is the part that actually makes contact with the segment on the This button is made of hot pressed copper provided with ears 11. 12 represents an elongated spring member preferably made of phosphor-bronze. This member is notched on opposite sides of one end at 13 and is provided with holes 14 for securing it to a suitable support. 15 represents a copper shunt made of two or more difierent pieces of sheet copper. This shunt is the same shape as the spring strip 12, be-
ing provided with similar notches 16 which coincide with the notches 13 on the sprin strip when the two parts are superim ose The shunt in its fiat condition is slightly 921. Serial 10. 805.911.
longer than the sprin strip 12 in order to provide forv the usuaF loop 17 to permit a sli ht extension under bendin Slotted ho as 18 are provided to coinci e with the holes 14 for the supporting screws. A washer 19, likewise notched at 20, to correspond'to the notches 13 and 16, is provided to be superimposed upon the copper shunt.
This washer is preferably of spring tempered sheet'steel.
1 shows the parts assembled. The
While I have described my invention as embodied in concrete form and as operating in a specific manner in accordance with from the spirit of my invention the scope of which is set forth in the annexed claims.
What I claim as new and desire to secure by Letters Patent of the United States, is
1. A controller finger comprising an elongated spring member having a notched end and a contact button provided with ears which enter'the notches and are bent over the sp g andpressed down so as to firmly grip the spring member between the bent over pdbrtion of the ears and the main body of the utton.
23% controller finger comprising an eloncenter the notches and are bent over and p down so as to firmly grip the spring member between the bent: over ortion of the ears and the main body of t e button.
3. A controller finger comprising an elongated spring member having one end provided with oppositely disposed notches and a contact button provided with integral ears which enter the notches and are bent over and pressed down so as to firmly grip the ring meinber between the bent over portion of the ears and the main body of the button. I r
4. A controller finger comprising an elongated springlmember having a notched end, a similarly s aped and notched copper shunt pressed, down; so asto firmly grip noon-roe superim osed thereon and a contact button with ears which enter the notches rovid 1n the two parts and are bent over and the said parts between the bent over portion of the ears and the main body of the button.
5. A controller finger com rising an elongated spring member provi ed at one end with oppositely disposed notches, a similar shaped notched copper shunt su rimposed thereon, a similarly notched meta l icwas superimposed on said shunt and a contact button provided with integral ears which her enter the notches in said parts and are bent over and ressed down onto the washer so nsnnnsr A. snosnnen.
