CRANK-HOLDER.

Specification of Letters Patent. Patented Dec. 23, 1919.

Application filed. June 23. 1919. Serial No. 305,954.

ToaZZ whom it may concern:

Be it known that I, URBAN HERMAN, a citizen of the United States, residing at Marshfield, in the county of Wood and State of Visconsin, have invented certain new and useful Improvements in Crank-Holders, of which the following is a specification.

This invention relates to crank holders, for motor vehicles.

The object of the invention is to provide a simple and efficient device for holding the engine cranking device out of engagement with the driving shaft after the engine has been started, and the handle of the crank in adjusted position.

Another object is to provide a device of this character, which is simple and cheap and is especially designed for attachment to a Ford car.

With the foregoing 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 changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings Figure 1 represents a side elevation of a portion of an engine crank case with parts broken out and this invention shown applied,

Fig. 2 is a top plan view thereof,

Fig. 3 is a transverse vertical section taken on the line 33 of Fig. 1, and

Fig. 4c is a detail perspective view of the holder detached.

In the embodiment illustrated, a crank case C of usual construction is shown, having the ordinary fan pulley P mounted thereon, and a bearing B which is designed to receive the starting crank c which has the usual handle H at its front end and a ratchet member or clutch R at its rear end. This starting crank 0 is slidable longitudinally in the bearing B to cause the ratchet R to move into and out of engagement with the cooperating clutch member carried by the driving shaft DS.

The device constituting this invention comprises a substantially J-shaped member 1, the short arm 2 of which is curved longitudinally to fit snugly around the head of the ratchet B when the latter is in retracted in operative position in Figs. 1 and 2, the" curved arm 2 frictionally engages the head of the ratchet B when the starting crank is in inoperative position, and when it is desired to start the engine, the crank is moved longitudinally inward, thus disengaging the ratchet head from the holder arm 2 and per.- mitting the clutch or ratchet to connect with the cooperating member on the driving shaft. After the engine has started, the

ratchet will be disengaged from the driving shaft clutch, and an outward pull exerted on the handle H will cause the ratchet head to be brought into operative engagement with the holder arm 2 and saidhandle H if desired, may be swung upward out of the way and will be held in this position by the holder.

From the above description it will be seen that this device which is extremely simple and cheap to manufacture may be applied to any automobile engine having the parts above set forth and is secured by the bolt 5 which also operates as a connector for the crank bearing B.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains and while I have described the principle of operation of the invention together with the device which I.

now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made as are within the scope of the claimed invention.

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

1. A crank holder comprising an attaching member having an arm provided with means to engage the ratchet of the starting crank and hold it in inoperative position.

2. A crank holder comprising an attaching member having an arm provided with means for frictionally engaging the ratchet head of the starting crank of an engine and hold it in inoperative position.

3. A crank holder comprising an attaching member having a hook-shaped arm extending laterally therefrom and adapted to frictionally engage the ratchet head of a starting crank and hold it in inoperative position.

4. A crank holder comprising a substantially J-shaped member, the short arm of which is curved longitudinally to form a hook for frictionally engaging the head of the crank ratchet to hold 1t in inoperative position.

5. A crank holder comprising a J-shaped attaching member, the short arm of which is curved longitudinally and its long arm apertured at its free end to receive an attaching bolt.

6. The combination with a crank case and an engine starting crank having a clutch member on its inner end; of a holder in the form' of a substantially J-shaped member fixed at the free end of its long arm to said crank case, with its short arm extending laterally inwardly and curved longitudinally to fit snugly around and frictionally engage said clutch member, the long arm being arranged parallel with the starting crank.

In testimony whereof I afliX my signature in presence of two witnesses.

URBAN HERMAN.
