Application filed May 17,

To 117/ whom it may concern:

lie it known that 1, llous'rox M. tanuoim, a citizen of the United States, residing at San Antonio in the county of Bexar and State of Texas, have invented a new and useful Attachment tor Automobiles. of which the following is a specification.

itis the object ot this invention to provide a simple and inexpensive structure, adapted to be n'iounted upon auttuuobiles and other motor propc led vehicles, the device being so constructed that a spring motor may be employed for giving initial movementto the shaft of he engine whereby the vehicle is propelled. Another object of the invention is to provide a novel means for putting the spring motor under tension, to provide novel means for operatively connecting the spring motor with the engine shaft, andwto provide novel means for releasing the spring motor, so that it may operate upon the engine shaft to give an initial movement to the saute.

The drawings show typical embodiments merely, and it is to be understood that. changes, properly falling within the scope of what is claimed, may be made without d eparting from the spirit of the invention.

In the accompanying drawiugs,-Figur'e 1 shows the invention in side elt'w'atiou, parts being broken a way and sectioned: Fig.2 is a top plan, parts being removed; Fig. 3 is an end elevation; and Fig. l is a vertical transverse section upon the line ltll of Fig. 1.

In the drawings. that end ot' the structure to whiclrthe letter A. is applied, obviously is the front end, and the terms trout,"

rear and the like will be selected accordingly.

The support in which the device is housed, is, in the present instance, shown in the form of a vehicle framcl. Fixed to and rising from the vehicle frame 1, is a trout plate 2, and a rear plate 3, spaced apart.

and 3, an intern'imliate plate i, the outline o't which is seen most clearly in Fig. -l of the drawings. It will there be seen that this in termediate plate 1 is U-shaped in'genoral Outline, there being an arm 5 depending vertically from the intermediate, upper portion of the plate 4.

within the frame 1 in any common and well known manner, the engine shaft being denoted by the nume'al 7, and the fly-Wheel thereof by the numeral 8. The engine and the spring motor for imparting an initial movementto the crank of the engine, are housed beneath a hood 9, the construction being common and well known.

.lourualed tor rotation at its forward end in the front plate 2, is an auxiliary shaft 10, the rear endo'f which incloses, and is rotatable. upon, the forwardend of the engine shaft 7. Fixed to the auxiliary shaft 10, is a pinion ll. The auxiliary shaft 10 is actuated by a spiral spring 12, one end of which is secured at, let to the shaft 10, the other end of the spring being secured to the front plate 2, as shown at- 15. If desired, the spring 12 may be housed within asuitablc Case 16.

Operating upon the auxiliary shaft 10 is a clutch 17, adapted, when slid rearwardly, to interlock with a transverse pin 18, or with a similar element adapted to a like end, located upon the engine shaft 7. Disposed above the shafts T and 10, and journaled for 3"and 4, is a winding shaft it), the rear end of which protrudes through th plate 3. the protruding end of the shaft 19 being provided with a suitable operating wheel 2U, or the like, whereby the shaft it) may be rotated. Secured to the forward end of the winding shatt' l9, and located between the plates 2 and 4, is a pin ion 21. in mesh with the pinion it, and oi. considerably less diau'ieter than the last named pinion. This pinion 2t as seen in Fig. 1. so constructed that when the winding shatt it) is moved rearwardly, the said pinion 21 may be drawn rearwardly with the sl tit 19, out of engagement with the pinion it. A compression spring 29 surrounds the winding shatt til, the spring hearing at its rear'end upon the plate 4, and at. its forward end against the pinion 21, the spring 2; obviously acting to hold the pinion 21 normally in mesh with the pinion 't't.

Secured to the wiut ling shatt 19, to the rear oi the plate 4. is a ratchet '23, adapted to engage a pawl 24-, pivotally mounted upon the plate 4 and actuated by a spring It will be seen that this atchcti 2S, en-

engagement with'the ratchet 23, when the -shaft"28 is rotated as hereinafter described.

gaging the plate 4, serves to limit the forward movement of the shaft 19 under the i action of the spring 22. The pawl and ratchet mechanism 23, 24, constitutes the primary means for preventing the winding shaft 19 from rotating/L under the action of the spring 12 of the winding shaft against rotation is provided This secondary holding means consists of a pawl 26, pivoted uponthe plate 4, and adapted to engage the ratchet- 23, adjacent the lowermost portion thereof. The pawl 26 is held normally in engagement with the ratchet 23, by means of a spring 27, secured at one end to the plate 4, and at the other end bearing against the Slidably and rotatably mounted in the plates 3 and 4, and located to one side of the winding shaft 19, is a shaft28, adapted to operate the clutch 1-7, the shaft 28 being hereinafter referred to as the clutch operating shaft. The clutch operating shaft- 28 carries a finger 29, adapted to bear against the lower pawl 26, to move the same out of One end of the shaft 28 protrudes rearwardly through the plate 3, and upon the protruding ends of the shafts 28 and 19, is mounted a connection 30, in which the winding shaft 19 is readily rotatable. In this connection 30 is, as seen most clearly in Fig. 2, a transverse slot Through this slot 32 extends a lever 31, the same being operatively connected with the clutch shaft 28. This lever 31 serves at once, as a means fo operating the shaft 28, and as a means for retaining the rear end of the shaft 28 within the connection 30,-so that the said shaft 28 may have a limited rotary movement within the connection. Secured to the forward face of the plate 3, is a spring 33, the forward end of which engages beneath a projection 34 upon the'clutchshaft 28.

Any suitable means for connectingthc clutch shaft 28 operatively with the clutch 17, may be employed. In the present instance, a lever 36 is extended through the arm 5 of the-intermediate plate 4, and fulcrumed, intermediate its ends thereupon, as shown at 35. Secured to the clutch shaft 28, is an arm 37, provided at its lower end with atransverse, arcuate head 38, adapted to bear against the upper end of the lever 36, the lower end of the lever 36'being adapted, as seen most clearly in Fig. 1, to bear against the clutch 17 to slide the same rearwardly to engage the engine shaft 7.

. Fulcruined at 40, upon the plate 3, s a depending foot lever 39, the upper end of which engages the connection 30. between the rearwardly protruding ends of the shafts 28 and 19. Protruding rearwardl y from the plate 3, is a stop pin 41, adapted to be engaged by the lever 31, when the same is I moved transversely of the vehicle.

Presupposing that the parts are in the positions shown in Fig. 1 of the drawings, the handle 42 of the operating wheel 20 is seized, the. winding shaft 19 being rotated. The pinion 21,fixed upon the forward end of the winding shaft 19, will engage the pinion 11, fixed upon the auxiliary shaft 10, rotating the auxiliary shaft 10, and putting the spring 12 under tension. During this operation, the

clutch 17 is out of engagement with'the -engine shaft 7 The pawls 24 and 26, engaging the ratchet 23, will prevent the winding shaft 19 fr an rotating under the action of the spring 12. \Vhen the spring 12 is thus put under tension, the device is operative, at the will of the operator, to impart initial movement to the engine shaft 7. When it is desired to start the rotation of the engine shaft 7, the lever 31, is moved in the direction of the arrow B of Fig. 3, until ,it bears against the stop pin 41, which will indicate that the clutch 17 is properly connected with the engine shaft 7. It may be that when the lever 31 is moved in the direction of the arrow B, the lever may not-come into contact with the stop pin 41, this fact resulting from the relative positions of the clutch 17 and the pin 18 upon the engine sha" 7. In such instance, pressure upon the lever 31 may be applied with one hand, the operating wheel 20 being rotated through a small arc, with the other hand. This rotation of the operating wheel 20 will so position the clutch 17 with respect to the engine shaft 7, that the lever 31 may be brought into contact with the stop pin 41, thus indicating that the clutch is properly connected with the engine shaft. The manner. in which the lever 31 operates to-move the clutch 17 rearwardly, is as follows: Obviously, when the lever- 31 ,is moved in the direction of the arrow B of Fig. 3, the shaft 28 will be rotated through a small are, in the same direction. This movement of the shaft 28 will cause the arm 37 to tilt, the curved head 38 bearing against the upper end of the lever 36,, and

causing theupper end of the lever to tiltforwardly, the lower end of'the lever being tilted rearwardly, to engage the clutch 17,

the clutch being thus slid rearwardly to engage with the engine shaft 7. After the clutch 17 has thus been slid to engage the engine shaft 7, the lever 31 may be moved back to its original position, in the direction opposite to that indicated by the arrow B in Fig. 1.. \Vhen it is desired to actuate the engine shaft 7, the lower end of the foot lever 39 may be pressed forwardly, the upper end of the foot lever engaging the connection 30, between theshafts 19 and 28, sliding the said shafts rearwardly, and

shaft 7.

drawing the pinion 21 out of mesh with the pinion 11. Thus the pinion 11, together with the shaft 10, will be free to rotate under the action of the spring 12, the spring 12 thus acting, upon the will of the operator, to impart an initial movement to the engine It has been pointed out hereinbefore, that the lever 31 may be. moved manually in a direction opposite to the arrow'B of Fig. llowever, this manipulation of the lever not necessary. For, if desired, the shaft 28 may be provided with the projection 34:, which, being vengaged by the spring 33, will rotate the shaft, so that the upper end of the ,lever 31 is normally spaced 21)1I't from the stop pin il.

hen it is desired to operate the winding shaft 19 as hcreinbefore described, to put the spring 12 under tension, the operator may throw the upper end of the lever 31 in the direction of the arrow B to a slight extent. rotating the shaft 28, and causing the finger 29 thereof to engagethe pawl 26, holding the said pawl 26 out of engagement with the ratchet J}. In such instance, the winding shaft 19 held by the pawl 24, alone, the additional friction imposed by the pawl 26 being thus removed, during the operation of putting the spring 12 under tension.
