moved from the crank shaft extension in a simple and expeditious manner.

The nature and advantages of the inven tion will be better understood when the following detailed description is read in connection with the accompanying drawings, the invention residing in'the construction, combination, and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals of reference indicate similar parts in the several views, and wherein Figure 1 is a side elevation of the motor vehicle crank shaft extension, which forms a component part of my invention, the operating handle being therefore removed and an end cap being applied in its stead.

Figure 2 is a view similar to Figure 1, the said end cap being shown in cross hand section.

F igure 3 is a view similar to Figures 1 and 2, but showing my removable cranking lever in position upon the end of said crank shaft extension.

Figure 1 is an end elevation of the" said cranking lever per se, and

Figure 5 is a perspective view of a collar member employed in conjunction with this invention.

Referring to the drawings in detail, my device constitutes the provision of a shaft 5, having secured to the inner end thereof at 6 a conventional form of clutch" member 7. In the practical application of my device to Ford type of automobile, the usual crank shaft extension is removed from its journal A after which my shaft 5 is positioned therein, in a manner more clearly shown in Figure 3.

After being positioned within the journal A, there is positioned upon the shaft 5 a coll r 8, the same b g irc mf ntially grooved as at 9, formed at its front face with a pocket 10. Adjacent the outer end of the said shaft 5, there i positioned a cross pin 11, and encircling the said shaft 5 between the cross pin 11, and the said collar 8 is a relatively strong coil spring 12, the inner end thereof engaging within the said pocket 10 of the collar for maintaining the same in face to face contact with the adjacent face of the journal A as well as maintaining the said clutch member 7 normally in face to face contact with the opposite end of said journal A.

The cranking lever designated 13 is a well known type, the upper end thereof being formed with a right angular extending head 14 within which i a socket 15, the front end of the said head being slotted at 16 upon diametrically opposite sides thereof for the reception of the ends of the cross pin 11 of the shaft 5. e

In view of the above description, it will at once be apparent that the clutch member 7 upon the inner end of the shaft 5 is normally maintained out of engagement with the co-operating clutch element upon the end of the motor crank shaft through the instrumentality of the coil spring 12 Whenever it is necessary to crank the engine, the cranking lever may be expeditiously placed upon the end of the shaft 5, this shaft engaging within the socket 15 of the head 14: at which time the shaft 5 may be slidinwardly of the journal A for consequently engaging the clutch element 7 with the corresponding clutch element upon the end of the motor crank shaft, whereby through a turning movement of the cranking lever 13 the engine may be cranked. In Figures 1 and 2, I have showna cap 17 for the end of the shaft 5 when the cranking lever 13 is removed therefrom. This cap consists of a relatively elongated and open ended cylinder formed at spaced points thereon with spring fingers 18, the ends of which are curved inwardly of the said cap for forming heads 19 which are adapted for engagement within the said circumferential groove 9 of the collar 8.

In view of the above description, it is believed by me that the advantages of a device of this character will be readily appreciated by those skilled in the art, and although I have herein shown and described the preferred embodiment of my invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the in vention as claimed.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

In combination with a shaft journaled in a bearing, a collar loosely mounted upon. the shaft and hearing at one face against the shaft bearing, spring means confined at one end upon the shaft and bearing at its opposite end against the collar to hold the same in contact with the bearing shaft, said collar being provided with a circumferentially located annular groove, a cap adapted to re ccive the end portion of the shaft and the said spring means, and adapted to snugly [it about the periphery of the collar and bear at one end against the shaft bearing, and resilient arms out and formed up from the material of the cap and disposed at spaced intervals around the cap, each of said arms having an inwardly disposed bend formed therein and in the vicinity of the free end thereof'to provide heads which are friction- 25 ally received in the groove of the collar.

In testimony whereof I afliX my signature.

MORRISE E. ROGERS.
