ENGINE-STARTER.
Specification of Letters Patent.
Patented Apr. 4, 1916.
To all whom it may concern Be it known that I, GEORGE Y. LAUCHIN, acitizen of the United States, residing at Crystal Falls, in the county of Iron and State of Michigan," have invented certain new anduseful Improvements in Engine- Starters, of which the following is a specification. g t
This invention relates to an engine starter, and more particularly to a manually operable starter for gas engines.
The principal object of the invention is to provide. an improved form of apparatus of this class which is simple and durable in construction and effective and efficient in operation. For the attainment of these ends and the accomplishment of other new and useful improvements, as will appear, the invention consists in the features of novelty in the construction,combination and arrangement of the several parts generally shown in the drawings and described in the spec1 fication, but more particularly pointed out 1n the appended claims.
In the accompanying drawings, Figure l is a plan view, partly in section, of a starter constructed in accordance with the principles of my invention showing its relation to the crank of an engine to be started; F 1g. 2 is an elevation, partly in section, of the mechanism in one position; Fig. 3 is a sectional plan view with the mechanism in another position; Fig. 4 is a view, partly in section, showing the knock-out mechanism,
" and Fig. 5 is a detail view, partly in section,
showing the operating mechanism. V
This invention comprises in general a palr of members connected to ratchets operating in opposite directions with a gripping shaft, one of the members being for manually operating the shaft in one direction of rotation and the other member constituting a knockout' for releasing the shaft from operative engagement when the engine, which is to be started, kicks back. i 1
Referring now more ;particularly to the drawings, the numeral 1 designates generallyan engine ,of the type to be started having a shaft 2 with projecting pins 3. The starter is secured to a suitable frame 4 fixed in relation to the engine The starter proper comprises a casing with sections '5 and 6 secured togetherby fastening devices 7, the casing being formed in the outer portion of the inside,
thereof with a projection 8 having a shoulder 9 with an opposite inclined face 10. The casing is also provided with a wedging portion 11 through which the rotatable and longitudinally movable shaft 12 extends. To the other end of the shaft adjacent the englne 1 is connected a gripper 13 with teeth adapted to be moved in engagement with the projecting pins 3 of the engine shaft, the teeth being formed with'inclined faces so that the shaft 12 turns the engine shaft 2 in one direction of rotation, but if the engine shaft should be turned in the opposite direction the shaft 12 will be knocked out by the wedging portion 11.
Secured to the shaft 12 is a toothed ratchet member 14 and end plates 15. Mounted on the ratchet member and one of the end plates is an operating member 16 having a peripheral groove 17 and provided wit a spring-pressed ratchet pawl 18 which is adapted to engage the teeth of the ratchet member 14 for moving the shaft in one direction of rotation when the operating member' is rotated. This operating member is free to rotate in the other direction, and if desired, ball-bearings 19 are provided for assisting the free rotation thereof. The casing is formed with an 5) adjacent the lower extremity thereof in which an anti-friction roller 21 is disposed, and through the aperture a flexible member 22 extends which is wound in the groove 17 of the operating member and is secured thereto by a pivotally mounted lug 23. en the flexible member 22 is manually "drawn from within the casing the operating member 16 is rotated in such a direction that the ratchet pawl engages the teeth of the ratchet member to rotate the shaft 12.
Extending from the side of the operating member 16 is a shouldered projection 24 adapted to engage the shoulder 9 of the projection in the casing, and this extension 24: is also formed with a cam surface 25 which is'adapted to engage and cooperate with the inclined face 10 (see Fig. 2) of the projection within the casing when the operating member is rotated from its inoperative position, as shown in Fig. 2, nearly one complete revolution in the operative direction. A knock-out member 26 is also mounted on the ratchet member 14 and one of the end plates 15 and has a ratchet pawl 27 to engage the teeth'of the ratchet when the shaft is r0 tated in the direction opposite to the direction of rotation produced by the operating member 16. This knock out member is formed with wedging projections 28 preferably surrounding the shaft 12 and the projections are adapted to be received between the wedging projections 11 of the casing for holding the member 26 against rotation when the shaft 12 is rotated by the operating member 16 and to cooperate with the projections 11 when the shaft 12 is rotated in the reverse direction for moving the shaft longitudi When the shaft 12 is rotated in the operative direction by means of the operating member 16 the latch 29 is moved upwardly into a dotted position, as shown by Fig. 2,
to permit the longitudinal movement of the shaft into engaging position, falling into locking position by its own weight when the shaft is returned to its inoperative position.
At the outer end of the casing it ispreferably provided with a projection 30 in which is mounted a bearing31 for the outer end of theshaft 12, and surroundingthe bearing within theprojection 30 is a coil spring 32, one end of which is secured to the 7 bearing 31. The other end of the spring is secured to a member 33, which is freely movable on the bearing, with an arm 34 extending upwardly over the adjacent end plate 15.
' for securing the member by means of .a
To secure the starterto the frame or support 4 it is preferably provided with perforated lugs 36 through which the fastening devices extend, and one portion of the casing is formed with a segmental curved housing portion 37 (see Fig. 1) for covering the knock-out device of which the member 26 has only a limited movement.
In operation it is necessary only to pull crating member 16, to which it is connected,
' will be rotated. The rotation of the operating member a slight distance releases it from engagement with the shoulder 8,.
whereupon the spring 32 presses the shaft and the member 16 longitudinally in the cas- 7 mg in the position shown by dotted outline in Fig. 2, at which time the wedging projection 28 of the knock-out member 26 has engaged with the wedging projection 11 of the projection of said member will engage with V the cam face 10 of the projection of the casing throwing the member 16 into inoperative position and moving the shaft 12 longitudinally whereupon the shaft-12, being disengaged from the engine shaft, the operating member'16 will be returned by its spring 32'to the inoperative position with the shoul- I der 2 1 in engagement with the shoulder 9. This action will also rewind the flexible member 22 in the groove and the starter ca be manually operatedas before. 7
Should the engine to be cranked ,kick' back at any time when an attempt is made to start it, the reverse rotation of the enginemay tend to produce a reverse rotation of the shaft 12.. A number of safeguards areprovided for this'condition. In
the first place the, 'teeth of the engaging member 13 are inclined so that they grip. in
one direction of rotation of the shaft 12 but do not grip in the other direction of rotation. The kick-out device proper is thrown into operation as soon as the direction of r01 tation of the shaft 12 is reversed whereby the wedging projections 28, which have been seated between the wedging projections 11 of the casing, are caused to engage the wedg- 1 ing projections: 11 thereby moving the shaft longitudinally and throwing the gripping the inoperative position and in position to'be again operated. I
It is obvious. that those skilled in the art to which this appertains may make various changes-in the construction, combination and arrangementof the several parts without departing from the spirit and scope of. the invention.
