Specification of Letters Patent.
Patented July as, 1914.
Application filed April 30, 1913. Serial No. 764,573.
To all whom, it may concern:
Be it known that I, FRANK MIsKvsKY,
a citizen of the United States, and a resident of Lynn, in the county of Essex and State of Massachusetts, have invented a new and Improved EngineStarter, of which the following is. a full, clear, and exact description.
This invention relates to an apparatus for starting automobiles or other engines, and it relates more particularly to a starting device of that type in which a single actuating means in the first part of its,
movement relatively connects the starting shaft with the crank shaft of the engine,
and during the remaining part of its movement causes the starting shaft; to rotate the crank shaft sufficiently to enable the engine to start. i e
The invention has for its generalobject to improve and simplify the construction and operation'of engine starting devices of the type disclosed in United States Letters Patent No. 1,047,103, granted to me December 10, 1912, whereby the apparatus will --be more reliable andefficient, and comparatively inexpensive to manufacture and install.
Another object of the invention is the provision of improved means for imparting longitudinal movement to the starting shaft to' operatively connect the same with the engine crank shaft and thereafter" to impart rotary movement to the starting shaft, said means serving to restore the parts to normal position when thd operator releases the actuator, and provision is made whereby thestarting shaft is automatically disconnected from the crank shaft in case of backfire,
\Vith these objects in view, and. others as will appear as the description proceeds, the lnventlon comprlses various novel features of construction and arrangement of parts which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.
Tn the accompanying drawings, which illustrate one embodiment of the invention, and wherein similar reference characters are employed to designate corresponding parts throughout the several views,=Figure l is a. view of the starting apparatus showing the samefapplicd to an automobile; Fig. i2 is an enlarged-side view with the parts in normal position and with a portion of the ratchet wheel broken away; Fig. 3 is a longitudinal section coincident withthe axis 0 the starting shaft; Fig. 4 is a view similar to Fig. 2 with the parts in a position occupied during the turning of the crank shaft of the engine; and Fi 5 is a plan View of the starting device wit the parts in the position shown in Fig. 2.
Referring to the drawings, A designates an ordinary automobile engine in which the shaft 1 is provided with a bevelgear 2 with which is adapted to mesh a bevel gear 3 of. the starting device, such bevel gear 3 be-' with the gear 2,
in this bracket or bearing 4.is a rotatable and longitudinally movable starting shaft 5, to which the miter gear 3 is fastened. Keyed to the end of the shaft 5 opposite from the gear 3 is a ratchet wheel 6, and spanning this ratchet wheel are bifurcations 7 of a'lever 8 which carries a pawl 9 that is adapted to engage the teeth 10 of the ratchet wheel 6, the parts being so disposed that when the lever 8 is moved in a clockwisedirection, Figs. 1- and 2, as for instance by the operating rod 11 connected with such lever, the ratchet wheel 6 and the shaft 5 will turn in the same direction.
As the gear 3 is normally out of mesh with the gear 2 it is necessary to impart a longi-- tudinal movement to the shaft 5 to cause such gears to mesh, and this resultcis obtained by employing the initial part of the rotary movement of the shaft by the use of means new to be described.
On the shaft 5 is a cam collar 12 that is provided in its periphery with a slot 13 having its ends a and b offset from each other and in this slot is arranged a roller 14 which is carried'by a plate 15 fastened to the bearing or bracket 4, and as a result, when the collar 12 is rotated, the roller 14 engaging in the cam slot 13 will cause the shaft 5 to move in a direction to mesh the gear 3 with the gear 2. A device is em loyed to oper- "atively connect the cam col ar 12 with the shaft 5 wil lever 8, so that the collar will rotate with the lever during the first part of the move: ment thereof. This device comprises a rib or catch block 16 carried by the hub 17-of the inner bifurcation 7 ofthe lever B, and cooperating with this catch block 16 is a pivoted hook or latch 18 that has a shoulder 19 that is engaged by the catch block 16, as
shown in Fig. 2. The hook or latch 18.is mounted on a pivot 20 carried by and proje'cting from the cam collar 12;and the latch has a heel 21 which is'adapted to strike an abutment 22 formed by the plate 15. When the collar 12 hasmoved a sufficient distance to cause the shaft 5 to shift longitudinally for the engagement of the gearwith the gear 2 at this point the latch orhook 18 is raised, as shown in Fig. 4, so that continued movement of the lever 8 will cause the shaft 5 to rotate and in turn impart rotation to the crank shaft of the engine. The catch block or rib 16 extends into a circular groove 12 in the collar 12, so as to provide a lostmotion connection between the lever' dand such collar, the extremity 12 of the groove 12 being a shoulder with which the project ing end-of the catch block 18 engages during the return or anti-clockwise movement of the lever, so that. the camcollar 12 will be restored ito normal position, whereby the gear 2. I
In order to prevent backfiring of the engine from injuring the starting device, pro- ;vision is made for causingthe automatic disengagement of the gear 3 froni'the gear 2;
'- and to accomplish this an arm :23 is carried by thecam collar .12, and on this arm is a pawl 24; which engages the ratchet wheel 6, so that: when the latter ismoved in the reverse direction'by backfiring the arm 23 is carried with it sothat the collar 12 will be caused to. shift in a direction to move the shaft 5 longitudinally for releasing the ear 3 fromthe gear 2, the shifting of the shaft being effected by the roller 14: working in the cam groove 13 of the cam collar-l2.
In starting the engine the handle 25 of the operating or pull rod 11 is pulled upwardly by the operator while seated in the automobile, and this movement of the rod causesthe lever 8 to swing from the full to the dotted line position, Fig. 1. The initial position of the parts is shown in Fig. 2, and as the lever moves to the left the abutment 16 by engagin with the hook or latch causes the cam co lar 12 to move with the lever 8 as auni-v tary device until the shaft 5 is shifted longitudinally to engage the gear 3 with the gear 2, At this-point the heel 21 strikes the abutment 22 and releases the hook 18 from the abutment 16, so that continued movement of the iever'8 in the same direction as before will result in only a rotary movement of the v Patent:
be retracted to position where the gear 3 will be disengaged from the,
shaft 5, whereby the latter rotates the crank shaft. As soon as theengine has started the crank shaft will rotate the starter shaft 5 and cause the ratchet wheel 6 to slip past the pawls 9 and 24:. Theoperator now returns the pull rod 11 to normal position, so that the shaft 5 will be shifted longitudinally in a direction to release the gear 3 gear2.
From the foregoing description taken in connection with the accompanyingdrawings, the advantages of the method 0. operation and of the apparatus shown will be readily understood by those skilled in the art to.
which the invention appertains,.and while I have'described the apparatus which I -now consider to be the best embodiment thereof, I desire tohave it understood that the apparatus shown is merely illustrative, and
that such changes may be made when desired as are within the scope of the appended claims.
