Specification of Letters Patent.
Patented May 19,1908.
Application filed August at, 1907. Serial no. 389,973.
and State of New Jersey, have invented cer.
tain new and useful Improvements in Timers, of which the following is a specification, reference being had therein to the accompanying drawing.
My invention relates especially to electrical contact breakers-for sparking circuits of automobiles, and the like, and has for its object the provision of a simple and effective interrupter wherein the defects of the usual wipe-contact circuit interrupter are obviate-d.
To attain the desired end, my invention consists in the combination with a casing provided with one or more contact pieces, of a loose ring of less diameter than the chamber Within the casing, and a roller carried by a rotatable member adapted and arranged to move the ring in,an eccentric orbit, all of which will be hereinafter first fully described, and pointed out in the claims.
In the drawing, Figure 1 is a perspective View of a timer embodying my invention. F1 2 is a lon itudmal axial sectional view thereof. Fig. i1 is a i'ace view with the cover removed.
Similar numerals of reference, wherever they-occur, indicete' corresponding parts in all the figures.
1. is a casing made of'any pref rred mate rial. 2 is' a cover therefor.
3 is the chamber within the casing.
4 are binding posts, the construction of timer illustrated being provided with four,
. but it is obvious that my invention may be used with one or more circuits, as required. Each post 4- is secured. to a cap 5 which in .tui'ii is held to e perforated insulating piece 6 by screws 7, the piece tl'entcring a perforation 8 in the circumferential wall of the eas- .tending through the ing 1, 'whe reit gis held, as by it screw, 9.
10 1s a hollow conductingcontact-piece exlator 6, a. flange at t 2 outer extremity limiting the inward movement of the piece 10.
11 1s.- a conductingspring which forces the piece/I0 inward, this construction being particularly shown. in Fig. 2 of the drawing.
-12 en arnior holding the cesing'iin it lined position oerforation in the insu 13 is a sleeve projecting into the casing 1, adapted to be secured to a rotatable shaft by means of a set-screw, 1.4; the inner end of the sleeve beers a projection, 15 on which is fixed it ring 16 carrying ears 1'? whereon is pivoted a yoke 18, the free end thereof is forced outward by a spring 19.
20 is a roller mounted inthe yoke 18.
21 is a metallic ring, preferably mede of brass, of less diameter than the chamber 3,
said ring being held between the wall of the chamber and the roller 20.
In operation, as the sleet e 13 revolves, the ring 21 moves eccentrically, coming in contact with each of the ieces 10 in succession,
and as the ring is of ess diameter than the wall of the chamber wherein it moves, and also slips slightly, practically a new contact surface is presented to the pieces 10 with each revolution of the sleeve, preventing pitting or wear of the rin increasing the efliciency of the timer, and greatly augmenting its durability and life.
Having now fully described my invention, what I claim {LS new therein, and desire to secure bylictters Patent, is:
1. In a timer of the character herein specilied, the combination with a hollow casin contacts carried thereby, and arotatahe member located therein, of a spring-actuated roller carried by said member, and a loose ring having smooth inner and outer faces located. between the roller and the wall of the hollow casing.
A timer in which is comprised a hollow casing; a. plurality of insulate binding posts mounted on the periphery of the ass mg; movable contact-pieces extending into the hollow casing from the binding-posts; a rotatable member extending into the hollow casing; a yoke carried by the rotatable member; a roller jcurneled in said yoke, and a loose ring having smooth inner and outer faces, located between the roller and the wall of the hollow casing;
In testimonywiiereof I hereto afiix my signature in presence oi two witnesses.
