j To'all whom it may concern:

Be it known that I, SAMUEL HOWARD of Great Britain and Ireland, and resi ing at 48 London street, Norwich, in the county of orfolk, England, have invented certain new and useful Improvements in Devices for Starting Motors on -Motor-Oars from the Drivers Seat or Footboard, of which the following is a specification.

This invention relates to devices by which the motor upon a motor car can be started ment with a ratchet shaft.' Theobject of' from the drlvers seat or footboard by the -driver merelyjdepressing a pedal, and there by throwing a driving pawl into engage wheel on the motor th'isjinvention is to improve the apparatus above referred to in er to avoid shook being transmitted to 'the drivers' foot in back firing 'while it consists in the event of the motor isbeing started, and it providing a stop or buffer in such a position that it arrests the starting device and automatically withdraws the driving pawl when the device is rotated in the firing.

' f Reference will now be made companying drawings'in which, L Figures 1 and 2 are a front and rear View respectively showing the starting device in a position assumed when a backfire occurs. Fig.3 is a fragmentary side View. In the .drawings a device of the type befo'rejmentioned is illustrated, comprising a ratchet wheel, 6, keyed upon a motor shaft, a, apawl, d, pivotedjto' a plate, 0, which is free to be oscillated about the shaft, 4, by means of a foot rod, is, the latto the ac# operative stroke is adapted to engage the ar, g,j;on the the ratchet wheel, b. The foot rod, is, may

According to the present invention also a buffer or stop, 1-, tion that in the event of the motor-tackfiring while being started, the rod, k', strikes the buffer, r, which causes the rod, la, to move about its pin, 8, and to thereby bring a heel, 25, into engagement with a small leits end, 1:, to withdraw the pawl, 0?, through the medium of the rod, h. In th starting device is released from the motor and no damage is done to it.

By providlng a rubber pad or the like upon the' bufi'er any shock which otherwise occur is avoided. In'Fig. l the device is indicated in one might posltlon in dotted lines with the pawl, (Z, in

engagement with the ratchet wheel, 6, this being one position which it occupies during the starting ndwhile the footrod, k, is being depressed.

Should backfire occur, the ratchet wheel,

Instead of employing a rubber. or like'pad upon the buffer a spring or dash pot may be adopted in order to cushion any shock' which may occur.
