A pair of arcuate shaped spring arms 14rand 15 respectively are secured at diametrically opposite sides of the crank shaft 13, on the outer side of the crank case. These arms are secured by one of their ends to the case, while their opposite end portions are disposed outwardly of the case, in the manner shown in the drawings. These arms are arranged in'a circular manner. with the outwardly disposed free end portions to project in the same direction.

Normally the shank 9 extends upwardly from the collar 7 l Vhen it is desired to put the engine in operation, the operator takes hold of the handle and through the medium of the connection illustrated moves the shank 9 to the position shown in Figure 1, the said movement of the handle'6 being forward, and the said posiion of the shank 9 being the crank engaging position. Incident to the said movement of the shank 9 said shank 9 is engaged and moved by the arm 15, Figure 3, which brings about engagement of the ratchet on thecollar 7 with the ratchet on the shaft B. Thereupon the operator pulls the handle 6 rearwardly to start the engine, and on starting of the engine the arm 14 will co-act with the shank 9 and 7 from the shaft B.

The rod 4 is disconnected from the shank 9, as before described, in order that a drive belt may be put on or removed from the drive pulley on the shaft'B for the transmission of motion to some apparatus to be actuated by the engine.

It is to be understood that certain changes in the specific shape, size and materials may be resorted to, without departing from the spirit of the invention or the scope of the ap pended claims. 7

Having described this invention, What is claimed as new is:

1. Starting means for a tractor having a rear wheel fender and also having an internal combustion engine with a shaft on which is a ratchet, comprising 'a bearing on said fender, a transverse rock shaft in said bearing and equipped with arms, a bar pivotally connected to and extending rearwardly from one of said arms and disposed above said fender, a rod pivotally connected to and eX- tending downwardly from the other of-said arms, a collar loose on said engine shaft and having a ratchet opposed to that of the shaft and also having a shank pivotally connected to said rod, and arms mounted adjacent to the engine shaft for making and breaking connection between the collar and the engine shaft; one of said arms being adapted to enthereby disengage the collar ward on upward and rearward movement of the shank.

2. Starting. means for a tractor comprising an internal combustion engine having a shaft on which is a ratchet, including in combination a collar loose on said engine shaft and having a ratchet opposed to that of the shaft and also having a shank, and arms mounted adjacent to the engine shaft for making and breaking connection between the collar and the engine shaft; one of said arms being adapted to engage and move the shank laterally inward on downward and forward movement of the shank, and the other arm being adapted to engage and move the shank laterally outward on upward and rearward movement of the shank.

In testimony whereof I aflix my signature.
