STARTING DEVICE FOR EXPLOSION-ENGIN ES.

Specification of Letters Patent.

Application filed Kay 16, 191'1. Serial No. 627,584.

To all whom it may concern:

Be it known that I, Amer V. WINEGARDEN, a citizen of the United States, residing at Eldorad0,- in the county of Butler and State of Kansas, have invented a new and useful Starting Device for Explosion-Engines, of which the following is a specification.

This invention has reference to improvements in starting devices for explosion en'- gines, and its object is to provide a means whereby power may be stored to be utlhzed when desired to impart to the crank shaft of an explosion engine one or more rotations in order to establish the power cycle, whereafter the engine will continue to run in the usual manner, while the power may be again stored in the power storing mechanism by the runnihg engine, and the device be automaticallycut out from connection with the running engine when the capacity of the power storing means has been reached.

The invention comprises a device to be attached to an explosion engine, and more particularly to the engine of an automobile, whereby cranking is avoided, except under emergency conditions, when the engine may be cranked through the device the same as though the latter were not present. The power storing meansemployed is by preference a spring carried bya shaft, which in turn is coupled to the crank shaft of the engine, but the spring is connected to the shaft carrying it only at the will of the operator through suitable clutch mechanisms, while the arrangement is such that when the initial rotary impulse has been imparted to the'engine shaft, the spring is disconnected automatically, but may be again put into service at the will of the operator if the initial impulse proves insuflicient, it being customary to make the spring of such capacity as to be capable of imparting two or more starting impulses to the engine without rewinding. Furthermore, the construction is such that at the will of the operator the device may be so set that the running engine will cause a winding of the spring for the storing of power, and when the capacity of the spring is reached, it will operate a trip, which will cause the engine to be disconnected from the spring, but the latter is held against return movement to its initial unwound condition until purposely released by the operator.

The invention will be best understood from a consideration of the following detailed description, taken in connection with the accompanying drawings forming a part of this specification, with the understanding, however, that while the drawings show a practical form of the invention, it is susceptible of various modifications and changes while still retaining the salient'features of the invention, and, therefore, the invention is not limited to the exact showing of the drawings. I

In the drawings :F igure 1 is an elevation with parts in section of the starting device with so much of the showing of an explosion engine and adjacent parts of an automobile as will illustrate the application of the invention. l ig. 2 is a plan view on a larger scale than Fig. 1 of the starting device. Fig. 3 is an elevation of the starting device on a scale somewhat larger than that of Fig. 2. Fig. 4 is a longitudinal section with some parts in elevation of the struoture of Fig. 3. Fig. 5 is a section on the line 55 of Fig. 3. Fig. 6 is a perspective view of a trip device used in connection with-the structure.

Referring to the drawings, there is shown in Fig. 1 in outline a portion of a hood 1 of an automobile without any attempt to illustrate any special form of hood or any details of the structure, and there is shown also an engine 2 likewise illustrated indicat-ively and without attempt to show any details, it being understood that the engine is, as is customary, of the explosion type and is provided with a crank shaft 3, it being immaterial whetherthe engine be of the single or multi-cylinder form.

Coupled to and in line with the shaft 3 is another shaft 4 constituting the shaft of the starting device, and this shaft is pro vided with journal bearings 5 of any suitable type in which it may rotate freely. The end of the shaft 4 remote from that connected to the shaft 3 is sufiiciently extended to receive a crank 6, whereby the shaft may be rotated to impart an initial rotative movement to the engine shaft 3 should under any circumstances such procedure become necessary. The bearings 5 are shown as mounted upon a base or support 7 in the form of a plate, but it will be understood that this is largely indicative and the support for these hearings will depend entirely upon the particular type of automobile in i which the device is installed. At a point about midway of the distance between the bearings 5 the shaft carries-a sleeve 8 which may terminate in or have attached to it at one end a bevel gear 9, while atthe other end the sleeve has formed on it or attached to it a ratchet wheel 10, this ratchet wheel, however, having on one side an offset 11, adjacent which latter the ratchet wheel may have a smooth peripheral section 12 for a purpose which will presently appear. The sleeve, 8 is continued wheel 10. and terminates ina-radialfrib -13 adj acent which there is secured a hub 14 on the shaft 4 in any suitable manner, as by a set' screw 15 The hub 14 is provided with a suit-able number of radial pairs of ears 16, between which are pivoted dogs 17, "ea h with one end formed to engage the rib 13, which latter may be rounded orbe of any other appropriate Shape, so that the ends.

of the dogs 17 designedrto engage the rib 13 may have a sufficient expanse of engaging surface to provide an appropriate frictional engagement to cause the dogs and flange to move together under-circumstances to be described. The ends of the dogs 17 re- 'mote from the flange engaging ends are elongated and formed with cam surfaces '18 designed to be engaged by an annular rib 19 on a sleeve. 20 capable-of sliding 1011- gitudinally of the shaft 4. The hub 14 being secured to the shaft 4 by a set screw 15 acts as a stop or confining member for the 'sleeye 8, preventing it from moving longitud nally of theshaft 4 in one direction, while a set collar 21 held to the shaft 4 by a setscrew 22 is solocated as to engage the corresponding face of the gear9 and thus prevent longitudinal movement of the sleeve 8 in theother direction along the shaft 4.

The bevel gear 9 meshes with an idler bevel gear 23 mounted on a post 24 carried by the base 7, and this idler gear has meshing with it another bevel gear 25 mounted on the shaft 4 and held'against movement in one direction along said shaft by a set collar 26 held in place by a set screw 27. The bevel gear 25 has formed on it'on the face remote from the collar 26, a' hub 28 terminating in an annular radial flange 29 similar to the flange 13. Mounted on the shaft 4 is a hub 30 similar to the hub 14, and like the latter held to the shaft by a set screw 31. The hub 30 is formed with pairs of radial cars 32, each pair carrying a dog 33 like the dog 17 and for a similar purpose, each dog having at the end remoterom that designed to engage the flange 29 an inner bevel .edge 34 in the path of an annular rib 35 on a sleeve 36 similar to the sleeve 20 and capable of sliding longitudinally of the shaft 4.

beyond the ratchet 4 The purpose of the sleeves 20 and 36 is to engage the respective dogs 17 and 33 and cause them'to grip the respective flanges 13 and 29 and as the hubs l4 and 30 are fast to the shaft-4 the sleeve 8 will either be directly coupled as when coupled to the hub 14, or through the idler gear 23, as when coupled vto the hub 30, the arrangement being such that only one set of-dogsis active at a time to couple the sleeve 8 to the shaft 4.

Secured to the sleeve 8 by screws 37 or in any other appropriate manner is one end of a spring 38, which may be a flat spring of the spiral type of sufficient power for the purposes of the present invention. The other end of thespring 38 is shown in the drawings as formed into a loop 39 made fast to a spring 40 near the free end of the latter,

the spring being of the leaf type with the,

end remote from that connected to the spring 38 secured to the base 7, as indi cated at 41. The spring 40 is of such strength that the spring 38 may be wound to the full extent desired before the spring 40 will yield to any material extent, and it is only when the spring 38 is practically wound up that the spring 40 will yield sufficiently for thepurposes of the present invention.

Thea-ratchet wheel 10 is under the control of a. pawl 42 which may be piv ted to the baseas indicated at 43, and 'is' i eld to the ratchet wheel by a spring 44, whereby the pawl 42 is of the spring ty e, yielding to the passage of the teeth of the ratchet wheel, which latter are.'one-way teeth, and the pawl will by engaging these teeth prevent the spring from unwinding under the effect of the stored power. 8

Adjacent the bearings 5 are ings'45 carrying a longitudinally movable rod 46, this rod and the pawl 42 being s related that it extends between the pawl 42 and the ratchet wheel '10. Fast to the rod 46 are two forks 47, 48, respectively, in

straddling relation to the respective sleeves 20 and 36, the latter being each provide with an annular groov 49 f th lodging 0fthe fork? By this means the sleeves Q0 and 36 W111 articipate in longitudinal movements of t e rod 46, the forks holding the rod against rotative movements, since theseforks are made fast to the rod by suitable set screws 50, and the forks permit I thesleeves 20 and 36 to rotate with the shaft 4 when such movement is necessary. I will be. observed that the two sleeves move simultaneously in the same direction, but are presented oppositely to the respective dogs 17 and 33, so that when the sleeve 20 is moved into operative relation to the cam edges 18 of the dogs 17 the sleeve 36 is moved away from the cam edges 34 of the dog 33, and the-contrary is also true, from which it Will be seen that but one set ofdogs is movable actively into engagement with the respective flanges 13 or 29, as the case may be, to couple the sleeve 8 to the shaft 4. Since the spring on being wound must receive motion in one direction and on unwinding the same part of the spring moves in the opposite direction, itfollows that since'the shaft 4 must always rotate in the same direction as is the case in automobile engines, the motion imparted to the sleeve 8 by being coupled to the shaft 4 through the intermediary of the dogs 17 is contrary to that imparted to the sleeve 8 on being coupled to the shaft 4 by the dogs 33, the difference in motion being provided for by the idler gear 23.

Carried by the rod 46 are two blocks 51, 52, respectively, each fixed to the rod by a set screw 53 or by any other appropriate means, and one of these blocks, the block 51, has one end tapered, as indicated at 54.

Fast to the base 7 is a yoke 55 in which is pivoted an angle lever 56 having an arm 57 in overriding relation to the free end of the spring 40 and another arm 58 forked and straddling the rod 46 in position to engage the block 52. The lever 56 is under the control of a spring 59 connected at one end to the base 7 and at the other end by a link 60 to the lever 56 to one side of the pivot of this lever, which pivot is indicated at 61, and the arrangement is such that as the lever 56 is rocked on its pivot the link 60 will pass to one side or the other of the pivot in accordance with the direct-ion of rocking of the lever.

. It has already been stated that the rod 46 is movable longitudinall and to cause this movement there is provided a link 62 connecting the rod to a lever 63 which may be of the hand type and located within easy reach of the operator of the, automobile. This lever is made to play along a segment 64 which at an intermediate point may be provided with a notch 65 designed to receive a tongue 66 carried by the lever to lock the latter in an intermediate position, the resiliency of the lever being sufiicient to cause it to seat in the notch, but permitting the displacement of the tongue 66 from the notch at the will of the operator.

When the rod 46 is moved in a direction to cause the dogs 33 to'grip the flange 29, the block 52 is moved toward the arm 58 of the lever 56 and will act on this lever to cause the arm 57 to move toward the spring 40, the link 60 ultimately passing the ivot pin 61, and so acting as an elastic loc for holding the lever 56 in the new position, this position being shown in Fig. 3. At the same time the block 51 is carried in a direction away from the pawl 42. clutch formed of the dogs 33 and associated flange 29, the dogs being under the control of the sleeve 86, operates to wind the spring The 38, the idler gear 23 transmitting the motion from the gear 25 to the gear 9 and the latter being connected to the sleeve 8 winds the spring from the interior, while the outer end of the spring 38 is connected to the leaf spring 40. The winding continues until the spring has been put under its full tension, the ratchet 10 turning idly with relation to the pawl 42. Ultimately the tension of the spring 38 exceeds the resistance of the spring 40 and the latter follows the free end of the spring 38, but because the free end of the spring 40 is in underriding relation to the arm 57 the lever or trip 56 is moved toward and into engagement with the block 52, and this block is moved in a direction to cause a movement of the rod 46, which will move the sleeve 36 out of active engagement with the dogs 33, and the latter will ungrip from the flange 29, so that the shaft 4 is uncoupled from the spring and the winding ceases. The movement just described of the rod 46 is participated in by the lever 63, and'after the clutch dogs 33 have become inactive but before the clutch dogs 17 can become active, thelever-63 has reached the central locking position and the tongue 66 is dropped into the notch 65, thus stopping the rod 46 and holding it in the intermediate or neutral position, the trip 56 being now elastically locked by the link 60 and spring 59.

Suppose now that it is desirable to start the engine, the latter having in the meantime been stopped. The operator grasps the lever 63 and moves it in the appropriate direction, which is the opposite to that first considered, and is in the same direction as the movement of the rod 46 just described. The continued movement of the rod 46 in the one direction brings the taper end 54 of the block 51 into engagement with the pawl 42 and the latter is lifted away from locking engagement with the teeth of the ratchet 10, thus releasing the latter, but simultaneously with this movement the fork 47 has caused a movement of the sleeve 20 to actively engage the dogs 17. Since the pawl 42 has been moved. out of holding relation to the ratchet 10, the spring is free to expand, but since the hub 14 is, locked to the sleeve 8 by the clutch dogs 17, the expansive force of the spring is communicated to the shaft 4 and the latter is rotated. This rotative movement continues until the block 11 on the ratchet 10 is brought into engagement with the block 51, which latter carries an offset 67 in the path of this block and the said block is formed with a beveled face 68 so as to en age the offset to move the block 51 in a direction the reverse of which it was pioved to bring it into engagement with the pawb42 and the efiect of this movement is to return the lever 63 to the neutral locked position with the rod 46 also in the neutral or central position, thismovement causing the uncoupling of the hub 14 from the sleeve 8 and the release of the pawl 42 which at once returns into engagement with the periphery of the ratchet 10, but -in order to permit the action of the cam ortion 68 of the block 11, the smooth perip eral surface 12 is provided and the ratchet wheel 10 continues to rotate until the tooth beyond the smooth portion 12 is engaged by the pawl.

By suitably proportioning the parts the shaft 4 may be given a single rotation each time the spring is released and by making the spring of appropriate size it may be made to give several successive rotative movements to the shaft 4 at the will of the operator, the said operator releasing the spring to impart a single rotative movement to the shaft each time the lever 63 is manipulated in the proper direction. When the parts are in the intermediate or neutral position'the shaft 4 is wholly disconnected from the spring and may be rotated by the crank 6 to crank the engine in the usual manner, but such cranking is only necessary should some accident happen to the rest of the device, and is provided simply as an emergency means so that the breaklng down of any part of the starting device will not interfere with the starting of the engine by hand by means of thecrank.

It will be understood that when the device is installed in an automobile a suitable casing is P ovided, so that dust and dirt is excluded, but such casings being commonly used, it is not deemed necessary to show one in the drawings.
