CHARLES C. PHILLIPS, O'F CINCINNATI, OHIO, ASSIGNOR OF ONE-HALF TO ALBERT UNGER-BUEHLER, 0F CINCINNATI, OHIO. I

TIMER.

Application filed December 8, 1922.

To (all whom it may concern Be it known that I, CHARLES C. PHILLIPS, a citizen of the United States, and residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented a new ant useful Improvement in Timers, of which the following specification is a full disclosure.

This invention relates generally to current distributors and particularly to that type of distributors designed for use in automobile timers.

An object of the invention is to provide for positive and constant electrical connection or contact between the timer shaft and a pivoted wiper or brush element, which object is accomplished by providing direct relatively great surface contact between the terminals of the wiper-actuating spring disposed between the pivoted brush element or wiper and the timer shaft, one terminal. of the spring being curved to conform to the configuration of the timer shaft throughout a portion of its circumferential arc.

Another object of the invention is the pro vision of an oiling device as a part of and movable with the wiper or brush element, said wiper providing a tubular contact portion or sleeve in which is retained a wick element, which wick is adapted to be charged with oil at each revolution of the timer shaft by passing through the oil deposited at the bottom of the timer casing, and said wick adapted to supply oil by capillary action, over an extended period of time, after depletion of the oil supply in the casing.

Other objects will be more fully set forth in the description of the drawings, forming a part of this application, in which:

Figure 1 is a rear face view of the timer casing and related parts showing my improved wiper or brush and oiling device operatively disposed with reference thereto.

Figure 2 is a vertical section on line 2-2, of Fig. 1.

Figure 3 is a detail sectional view showing the relation of the spring terminal to the timer shaft.

Figure 4 is a view showing the action of the stop to prevent undue angular movement of the wiper when the timer casing is removed.

Figure 5 is a side elevation of the timer, with the parts positioned with correspondence to Fig. 4.

Serial No. 605,569.

Figure 6 is a fragmentary detail section showing the relation of the wick element to the casing in its lowermost position.

Figure 7 is a detail section showing the manner of attaching the wiper-carrying sleeve to the timer shaft.

The numeral 1 designates the timer casing, in this instance, of a Ford type, adapted for rotative engagement with one end of the engine casing, indicated in dot-and-dash lines, Fig. 2.

The timer shaft is indicated at 3 and is centrally located with respect to the casing 1. WVithin the casing is a timer contactcarrying ring 4 provided with contacts 5 connected with usual binding posts 6, all the foregoing parts being of well known construction.

My improved brush comprises a shaftengaging element 10 composed of a sleeve 11 having radial spaced lugs 12 extending laterally therefrom and having a circumferential slot 13 extending therethrough, a portion of the slot lying between said lugs. The lugs are pierced for the reception of a pivot 14, which pivot traverses eyes 15 of the wiper element 16, hereinafter described.

The sleeve 11 is slotted at its outer end as at and the timer shaft is bored at 21 for the reception of the shank of a pin 22, the head of which engages the slot 20 and prevents rotation of the sleeve upon the shaft. Disengagement of the pin 22 is prevented by a rimmed Washer 25 placed over a screw threaded extension 26 at the outer end of the timer shaft, said extension being engaged by a nut 27 for clampingly holding the washer in position.

The wiper element 16 is formed from a. sheet metal strip, one end of which is circularly turned as at 30 to form a tubular sleeve as a contact or brush and for supporting and securing a wick 31 therein, in this case, of cylindrical formation, and projecting laterally one side of the sleeve 30. The opposite end of the element 16 is saw-slitted longitudinally to provide three tangs, the outermost of which are circularly bent to form the aligned bearing eyes 15, the central tang being curved upwardly and then downwardly to form a stop for engagement with the sleeve 11 to limit the angular movement of the element 16.

The wick is designed to be saturated with about the pivot 14 and having its one termina-l 4L1 engaged fiatwise against the element 16 and its other opposite terminal 4L2 disposed within the slot 13 and against the timer shaft, this terminal being bent to engage the shaft throughout a considerable portion of its circumferential arc.

The upper extremity 13 of the slot 13 is so related to the terminal 42 as to form a stopifor limiting the inward movement of said terminal when the sleeve 11 is removed from the shaft, disposing said terminal portion with relation to the bore-of the sleeve, in such manner that the device may be thrust over the end of the timer shaft without interference of the spring as a stop to prevent convenient engagement there-wit-h, the terminal portion of the spring, by engagement with the end of the shaft, being pushed outwardly.

Having described my invention, 1 claim:

1. A current distributor brush of the character described,.comprising an attaching element composed of a sleeve having a pair of opposing spaced radial lugs extending therefrom, a wiper element formed of a flat metal strip having a tubular free end and an opposite end shaped to provide a pair of opposing spaced eyes for pivotally connecting the wiper element to and between the lugs, and an intermediate curved extension to provide a stop element adapted to engage the sleeve of said attaching element 7 lugs, said slot adapted to permit engagement of a current carrying element with the timer shaft, a wiper element pivoted between said lugs and having a tubular contact end and wick therein, and a spring between said elements having one end engaged with said wiper element and the opposite end within said slot.

3. In combination with a timer including the timer shaft, a raceway and easing, a current distributing brush comprising an attaching element composed of a-sleeve having radial lugs thereon and having an arcuate circumterentially disposed slot extending through said sleeve, a wiper element pivoted between said lugs, having a tubular contact end and wick therein, and a spring between said element having opposite terminals respectively engaged with said slot and-against said shaft, the shaft engaging end of said spring conforming to the shaft surface throughout a portion ofits arc whereby intimate, contact is maintained and eificient electrical connection assured between said shaft and wiper element.

In witness whereof, I hereunto subscribe my name, as attested by the'two subscribing witnesses.

CHARLES C. PHILLIPS.
