STARTING APPARATUS FOR AUTOMOBILES AND THE LIE.

To all juhom it may concern:

Be it known that I, SAMUEL .J. "EVANS,

citizen of the United States, residing at.

ing the engine for the operator to leave the machine and perform the manipulation known as cranking. Besldes the inconven- -ience this cranking operation is a dangerous one owing to the liability of an explosion taking place prematurely and causing the crank to fly backwardly and strike the'operator. With my invention an accident of this kind ifs impossible and the whole operation may be conveniently and safely per- I formed by the chauffeur.

The invention consists in the features and combination and arrangement of parts hereinafter described and particularly pointed out in the claims.

In the accompanying drawing, Figure 1 is a plan view of my invention as combined with the fly-wheel of the engine, parts being in section and some parts being omitted. Fig. 2 is an elevation of a portion of the starting shaft, and the starting mechanism parts being in section. Fig. 3 is'a detail view-of the relation of the starting lever to the spark adjusting connections and showing means whereby the premature ignition of the charge is rendered impossible, that is, in relation to the position of the starting appliances. ,Fig' is a detail. 1

In these drawings 1 is a crank shaft of the engine having its bearings in the frame, one of which bearings is indicated at 2, and this shaft carries the flywheel 3 as ordinarily.

A transmission shaft 4 is arranged in line with the engine shaft, the end of this starting shaft projecting into the hub 5 of the fly-wheel and finding a bearing at this point upon brass bushing 6. The fly-wheel carries a clutch member 7 attached thereto by a casing 8 on which the clutch member is Specification of Letters Patent.

formed, said casing having its arms or rim attached by screws 9 to the fly-wheel. The

companion clutch member 10 is carried by a sleeve 11 adaptedto turn on the supporting shaft or rod 1, this sleeve finding a bearing in a frame 12 which is adapted to have longitudinal sliding movement along the support or shaft 4, said frame haVina second bearing portion 13 on the said slh support and having also an extension or ortion 14 in which bears the end of a sha t or rod 15, which also finds a hearing at 16 on the frame, and which latter shaft carries fixed thereto a starting lever 17:. On the reduced portion of the shaft 15 at the inner end thereof is fixed a segmental gear 18 which meshes with a bevel gear 19 connected with the sleeve 11 and the clutch 10. The

aft orclutch memberlO together with its gear 19 and frame carrying these parts is under the pressure of a spring 20 surrounding the shaft or support 4 and bearing atone end against a collar 21 fixed on the said shaft by a set screw 22. This spring tends to press the clutch section 10 into engagement with theclutch section 7 and when the parts are in engagement a movement of the hand lever 17 from the position indicated in Fig. 3 in dotted lines toward the left, will, through the segment and the gear 19, operate the clutch to rotate the fly-wheel and thus start the engine.

I have provided means whereby as soon as the movement of the lever '17 is completed and the fly-wheel is set in motion the clutch -member 10 will be retracted from the clutch member 7 so as tolet the latter rotate freely without contact with the'clutch member 1.0,'

thus avoiding the ratchet noise which would otherwise occur if'the teeth of the member 7 were allowed to run over the teeth of the member 10. For this purpose the clutch member 10 together with the gear 19 and frame associated with these parts are retracted automatically as the final movement. of the hand lever is completed and in order to effect this result I have provided the segment lever 18 with an extension 22 which extension carries a roller 23 arranged in the final parts of the turning movement of the segment to strike against the fixed lug 24 on the frame, which acting as a fixed fulcrum will cause the frame, together with the clutch member, the bevel gear, the shaft- 15, all to be retracted and thus withdraw arm 29 the chitch member 10 from engagement with theclutch member 7 and as this movement is completed-the lever 17 has arrived at the position in which it will be locked to the segment 25 and the engine may now continue its movement while the clutch members 10 and 7 are out of engagement. It will be observed that the bearing 16 is provided with an enlarged opening or slot to allow the lateral shifting movement of the shaft 15.

Inorder to prevent accidents due to premature sparking or rather to the fact that the sparking has not beenadjusted properly before the starting manipulation is performed, I provide means to obstruct-the movement of the handlever 17 until after thevs arking device has been properly 'adjuste to 'give the spark at the right moment ating lever having a detent 35 adapte to engage in one of a series of notches in a sector 36 which will hold the lever in any position to which it may be adjusted. The

path of the shoulder 27 on the disk 26. The

, arm 29 is connected with a rod 38 extending I ah arm 39 belonging to this device.

to the sparker or timer and connected with In order to set the sparker or timer in correct position the lever 33 is operated, and this movement will also adjust the in 28 in relation to the shoulder of the d1sk'26. The

relation of the parts is such that if the spark retarder is not 1n proper position to furnish the spark at the ri ht period in relation to the stroke of the plston, the pin 28 will be in position to obstruct the movement of the disk, 26 by the shoulder thereof coming against the pin, and under this condition it will not be possible to operate the startin lever 17 to a position where it may be eifiectivel worked for startin the engine but on e contrary it will rst be necessary to adjust the spark retarder by the operation of the lever 33 and the described connections before the lever 17 can be used to set the fly-wheel in motion and thus start the engine. The position of the parts in Fig. 3 is that assumed by them when the spark retarder has been adjusted to proper position and the lever 17 is in position to be operated. At this time the clutch member %)0 is in engagement with the clutch memi I have provided means whereby when the in retracte carries the pin 28 which is in the starting mechanism above described of gear at which time the lever 17 'isat the is out extreme left hand limit of its throw, and it v is desired to throw the clutch into operation for startingf the engine the objectionable noise or e ectwhich would result from throwing the clutch member 10 while in revolution into engagement'with the station-.

ary clutch member 7, is avoided. This means consists of a foot lever 40 pivoted-to the fixed main frame at 41 andghavin-g'a pin or roller 42 adapted to bear on a depending portion of the sliding frame above mentioned, which carries the starting sleeve, gear and clutch member. .By depressing this foot lever the frame together with the starting sleeve, gear andclutch member will hold position while the lever 17 is being moved from its left hand limit to the right hand limit of the segment 25 and is thus getting in a position for the starting stroke. During this time the segment will,

of course, rotate the gear and .the clutchmember 10, but this movement will be without eifect or objectionable results as the clutch member 10 will be held in its retracted position by the footlever while it is rotating. assumed its position for a new stroke the foot lever may be released'and the spring 20 will then move the frame together with the associated parts alongthe transmission shaft to throw .the clutch member 10 into engagement with the clutch member 7 and the parts will then beready for: a starting action.- I 1 The transmission shaft 4 is'driven through the friction clutch 43, the hub of which surrounds the said transmission shaft and has a flange 44 which is en aged by lugs 45 carried by rods 46 mova le longitudinally of the transmission shaft ingrooves 47 As soon as the lever 17 has therein. These rods connect with a ring or lug 48 fitted within a partly spherical body 49 surrounding the transmission shaft and to which is pivoted at 50 a lever 51 which is pivoted to the main frame at 52. This lever connects with a second lever 53 and upon operating this the rods 46 willbe moved longitudinally of the transmission shaft 20 3 as to throw the friction clutch member into or out of engagement with the flywheel, said friction clutch member being partly inclosed by the said fly-wheel. A spring is preferably employed as at 5-1 to press the friction clutch member normally into engagement with the fly-wheel.

It will be observed that the starting gear is arranged on the rear side of the fiy wheel, that is upon the same side upon which the transmission clutch 43 is located and the transmission connection. So far as'I am aware I am the first to devise means whereby the engine may be started through power applied at the clutch side of the fly wheel.

This result I accomplish by the use of the shell or frame 8'which is attached to the rear side of the fly wheel which reaches over or incloses the transmission clutch and carries the starting gear clutch 7. which surrounds the transmission shaft.

It will be understood that while I have shown my invention as applied to automobiles, it is not limited in this respect as it may be used on launches tions where the starting useful or desirable.
