LINOIS TIMER ELEVATGR 1 0E) OAR-S.

Application filed February 2 T 0 all whom it may concern:

Be it known that I, Vrcron W. T1;

a citizen of the United States, residing at Waukegan, in the county of Lake and State of Illinois, have invented new and useful Improvement in Timer Elevator for Ford Cars, of which the following, is a speciiica tion.

My present invention relates to the provision of a timer elevator for Ford e Such a structure is for the purpose of elevating the timer from the front end or the c ;n shaft, where it is as present located, to a position where it will be more accessible and will be in a. position where it will less liable to fouling from grease fro? and from the road dirt-either solo it or thrown upon it by the drart er s by the fan as its present location is directly behind the fan.

It is not unusual for the cam-shaft either have originally or develop an aporeciable longitudinal movement or end-play" and the cam-shaft is not uniformly positioned with respect to the bolts for holdine; on the cover plate for the timing gears through which plate the cam-shaft extends. As the timer elevator is most conveniently secured in position by bolts fitting: into the same bolt holes which are at present used for holding the timing gears cover plate in position the variation in the location of these bolt holes with respect to the camshaft is liable to effect the operation of the timer elevator.

The particular object of my present invention is to provide a timer-elevator tructure, the operation of which will not be affected by end-play in the cam-shaft and which may be located with respect to cam-shaft and independently of a varia tion in the location of its points or attachment.

I prefer to attain the aforementioned objects by means of the structure illustrated in the accompanying drawings, in which- Figure 1 is a front elevation of a structure embodying my invention showing its relation to the cover plate of the timing gears.

Figure 2 is a vertical section on line Figure 1, and

Figure 3 is a vertical section on line 8-3, Figure 2.

Similar reference characters refer to similar parts throughout the several views.

The bracket for effecting the elevation a Serial No. 4455-421.

the timer comprises a lower portion aof d, and which seats, or approxe, in the seat 6 provided in the years cover plaie 7. Arisingi rom i a substantially vertical e 1ten- 1e upper end whereof is horizontaled to form a platform 9- for reand supporting the timer casing 10, Y 7 s bee moved from about the end the cam-sh t 11. it bored and interiorly threaded cap 12 'ded which is screwed upon the alended end of the cam-shaft. This as provided upon its circumference a wear and upon its outer end is a sea is ed slightly extended port-ion 14, which a socket 152 in the inner face of the i of the box-like cylindrical portion 4t of br ck t. he extended portion 14; on

' o 'ether with socket 15 esaction ot these parts through or by reason of end-ph y in the ca rn-shaft.

7 1e bracket is further provided with latarmg 2L 22 and which extend oppothree of the bolt holes in the timing irs cover plate. and these arms are bored v th holes somewhat larger than bolts 24 which are to pass through them so that the bracket w ll be located with relation to the cam-shaft and not by reason of its points of attachment.

The oil which works through from the engine or motor casing will serve to lubricate the spiral gears and the lower jouroi? the vertical shaft, or the spiral gears casing may be packed with a suitable bear- .r grease cup 25 is provided for lubricating the upper journal of the vertical shaft.

The timer casing 10 is held upon the platform 9 by means of a spring 26 extending from the top of the timer casing to a stud 27 arising from the platform, to which stud the spring is secured by a screw 28.

lVhat I claim new is:

1. Means for mounting and actuating a timer for ignition system of an internal combustion engine comprising a centrally bored and interiorly threaded spiral gear having an axial extension thereon, a casing having a socket for receiving the extension upon said gear, a shaft journaled in said casing, a second spiral gear mounted upon.

said shaft and Within said casing, an exten- I sion from said casing terminating in a timer casing platform located adjacent and surrounding the outer portion of said shaft, and means carried by said casing for securing the same as located through the interfitting of said first-mentioned gear With said cas- 'ng.

2. Means for mounting and actuating timer for ignition system of an internal combustion engine comprising a centrally bored and interiorly threaded spiral gear having an axial extension thereon, a casing having a socket for receiving the extension upon said gear, a shaft journaled in said casing, a second spiral gear mounted upon said shaft and Within said casing, an extension from said casing terminating in a timer casing platform located adjacent and surrounding the outer portion of said shaft, and arms extending from said casing for securing the same in desired position.

Means for mounting and actuating a timer for ignition system of an internal combustion engine comprising a spiral gear gear adapted to be mounted upon the end of the cam-shaft of the engine and having an axial extension, a casing having a socket for journalling the extension of said gear whereby said casing is located and a bearing is provided for the outer end of the cam-- shaft, a shaft journaled in said casing, a second spiral gear mounted upon said shaft and meshing With said first-mentioned gear, an extension from said casing terminating in a platform through Which said shaft extends, and arms extending from said casing to secure said casing as positioned through the interfitting of said first-mentioned gear therewith.
