STELLA HINDS SCHLUPP, OF SABEIHA, KANSAS.

TIMER.

Application filed July 27, 1923.

To all whom it may concern:

Be it known that I, STELLA Hines Sonnurr, a citizen of the United States, residing at Sabetha, in the county of Nemaha and State of Kansas, have invented a new and useful Timer, of which the following is a specification.

This invention aims to provide a novel form of timer casing, so constructed that it may be taken down readily for inspection or repairs, novel means being provided for holding the parts of the casing together and for imparting rocking movement to the casin Another object of the invention is to im prove the contact member which, being as sembled with the timing shaft traverses the terminals in the casing.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention can be F made without departing from the spirit of the invention.

In the accompanying drawings:

Figure 1 shows in front elevation, a device constructed in accordance with the invention, mounted on a portion of an internal combustion engine; Figure 2 is a side elevation wherein the casing is viewed edgewise; Figure 3 is a transverse section; Figure 4 is a rear end elevation; Figure 5 is an elevation showing the arm and the contact member; Figure 6 is a fragmental transverse sectional detail.

The device forming the subject matter of this application comprises a casing including an annular body 1 and a convexed cap 2. A disk-like carrier 3 made of insulating materail is located within the inner ends of the body 3 and the cap 2 and has a marginal flange 4 extending outwardly between the inner edges of the cap 2 and the body 1. In the flange at of the carrier 3, a notch or seat 5 is formed, as shown in Figure 6, this notch or seat being alined with a similar notch or seat, formed in the edge of the cap 2 and indicated at 6 in Figure 2. Within the casing, the carrier 3 is supplied with binding posts Serial No. 654,193.

7 having terminals 8 embedded in the carrier or track, in accordance with the common practice. The cap 2 has a sleeve 9 through which the conductors (not shown) on the binding posts pass.

One object of the invention is to provide, in a device of the class described, a member which has a three-fold ofiice, in that it serves as a radius arm whereby rocking movement may be imparted to the casing, the said member serving to prevent relative movement between the body 1 and the cap 2, and serving, also, as a clamp for holding the cap 2 on the body 1, with the flange 4 of the carrier 3 disposed between the cap and the body Having the foregoing consideration in mind, a bracket 10 is secured at 11 to the body 1 and extends transversely thereof, the bracket engaging in the notch or seat 5 of the flange 4 of the carrier or track 3, and in the notch or seat 6 which is formed in the edge of the convexed cap 2. The bracket 10, in view of the foregoing, obviously serves to hold the members 1 and 2 together for simul* taneous rotation. The bracket 10 is extended to form a loop-shaped arm 12 having an opening let adapted to receive the operating member 15 whereby the casing is rocked to secure a change in the timing. The loopshaped arm 12 is extended to form a spring clamp 16 having a boss 17 adapted to engage in a concavity 18 formed at the center of the cap 2, the clamp 16 serving to hold the cap in place. It will be obvious that the clamp 16 may be sprung outwardly, permitting the cap 2 and the carrier or track 3 to be disconnected readily and quickly from the body 1, it being possible, thus to take down the casing without the use of tools. A concaved recess 19 is formed in the boss 17 of the clamp 16. Any suitable means may be supplied for holding the casing in place. Thus, as shown in Figure 1, the gear case of an internal combustion engine is marked by the numeral 20, the breather pipe appearing at 21, and the numeral 22 designating a spring arm assembled with the breather pipe, the free end of the spring arm being adapted to be received in the concaved recess 17 of the spring clamp 16, to hold the body 1 against the gear case for rocking movement.

The timing shaft 23 of the engine projects into an opening 2 1 formed in the carrier or track 3. An arm 25 is secured at 26 to the shaft 23. The arm 25 has outstanding ears 27 carrying a pivot element 28 whereon a lever 29 is fulcrumed intermediate its ends, the lever being curved, as shown at 30 to conform to the cycle in which the terminalsT of Figure 4 are located. The lever 29 embodies a short arm 31, extended toward the member 25, and a long arm 32 extended away from the member and conveXed at its free end, as indicated at so asto traverse the track or carrier 3 and to cooperate with the terminals 8 without wearing the track or the terminals unduly. The lever 29 preferably is made of a single piece'o'l metal, twisted as shown at 34:, so that the short arm 31 of the lever stands at right angles to the long arm 32 or" the lever. With the short arm 31 of the lever is assembled a retractile spring 35, extended between the ears 2. and secured as indicated'at 36 to the arm 35, the sprin obviously, serving to hold the conveXed portion 33 of the lever 29 yieldably engaged with the track 3. 3

VJ hat is claimed is 1 1. In a device of the class described, a casing comprisinga body, a cap, and a. track therebetween, and a spring clamp secured at one end to the body, the other'end of the clamp bearing on the cap to hold the cap, the body and the track assembled, the clamp being provided with an intermediate operating arm.

2. In a device o1 the class described, a cas-- ing comprising a body, a cap, and a track a s arin clam 3 en 'a in the ca 3 to hold the 2D 2D 23 b cap, the body and the track assembled.

3. In a-device-ot the class described, a casing comprising a body, a cap, and a track therebetween, a bracket on the body, the track and the cap having elements which interengage with the bracket to hold the cap, a

the track ant the body together for simultaneous rotation, the bracket being extended to form an operating arm, and the operating arm being prolonged on a spring clamp engaging the cap, to hold the cap, the track and the body assembled.

at. In a device of the class described, a casing comprising a body, a cap and 'atrack therebetween, and means for holding the cap, the body and the track against relative circumferential movement, said means embodyi a part cooperating with the cap to bind the cap, the track and the body 'to gether, and comprising projecting means wnereby rotation maybe imparted tothe casing.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature;

Mas. STELLA HINDS SCHLUPP.
