I sranrme-cnann'nonnnnf Application filed December is, was Seria1"No. 755, 733.

I To all whom itmag aoncem: V Be it known that I,,R0BERT H. VIssEn', a citizen of the United. States, residing at of Macoupin and] State of Illinois, have invented certain new.

and. useful Improvements in. Starting- Crank Holders, of which the .followin is a specification, reference being had to t e ac-' companying' drawings.

Thlsinvention relates to starting crank holders for the starting cranks of automo biles, tractors and the like. i

,An important object of the invention is to provide a device-of this characterior secnrely holding starting cranks of the vehi cles in one. position thereof to prevent the unpleasant rattling and squeaking noises caused by oscillation and vibration of the crank in its bearing. r

An important object of the invention is 7 to provide a device' of this character, the apstalled on the vehicle,

against movement; engagement with the plication of which necessitates nochanges whatever in the present structure'of the veh-iclel.

A still further object of the invention-is toprovide a device ofthis' character which will, in event of the breakage of the spring norms lly'employed for holding the starting crank out of engagement with the crank shaft of the engine, securely hold the crank crankshaft. a ,o

"A still. further object is to provide a de-., viceof this character which may be cheaply v and many produced and as readily in These and other objects Iattain by the construction shown-in the accompanying: drawings, wherein for the purpose of illuse tration is shown apreferred embodiment of my invention and wherein:-,

1 Figure 1 is a perspective view showing a. startingcrank holder constructed in accords, ance with my invention applied to the front end bearing-of a vehicle; l

Figure 2 is a vertical sectional: through; Z, U"

view there- Referring now more particularly to the 7 lar 22 :having' at its forward-edge .a proof-jthe engine of the vehicle. This front end'ibearing receives a hearing 511 formed upon thefront end of thecrank case which bearing 11in. turn rotatably receives a crank 12' to maintain the same insali'gnment with the crank shaft 15 of the; engine. This crank-has secured rtheretonne 'end' of a spring 14, theopposi-te end of which bears against theaforward end of the I bearing 12 to urge the crank iorwardly and to with dral the crank from engagement with the 1580' that thestarting head-16 will have itsratchet'teethl? out of engagement with the starting pin 318 of the crank shaft 15. The starting, head. of the crank" 13 is' usually secured in position b a pin (not herein shown): which in acoor ance with my invention is'replaced by a bolt 19. q I

Inaccordance with my invention I -pro-, vide a plate '20 opposing the forward end of the starting head and having-an opening 21 formed therein. Upon the starting head by means of the bolt 19 I securea col jecting latch lug- 23 secured vto the collar by ja reduced neck 24 producing a rear- Wardly fac'inglatching shoulder 25;, Due to the factothatthepexte'rior surface'ofthe starting head-16 is'usnally unfinished and,

"therefore, subject to variations-in size the collar'22 is split as atx26 so thatfjit maybe T readily varied' in size to fit the startin head. Thiscollar. is provided with openings 271501 the pasmgecofthe bolt 19. The opening 21 o'fthe plate '20 is of sufiicient Width to permit the passage therethrough of thejlatching h1g2? and the neck 24 is of the; same width as the thickness of the plateQG. v, a

Pivoted totthe plate 20'a's at 28 is a latch.

29ihaving a shoulder 30 adapted to engage against the rear face 31; This shoulder .30 is vertically disposed andx'fiatly engages against the rear face 31 of the latch lug 23 y when the latching has its shoulder 25 fully f engaged with the plate 20 at the opening 21 and is normallyiurged to this position by. a spring. 32 seated upon an integral extension 33 of the plate 20 'andabutting the 9 upper fac'eof. the latch. v This spring, when the latch "is in the last named position,

comes into engagement with the upper surface of the plate 20 and is accordingly inoperative to urge the latch further for a p urpose presentlytoappean v 1 V The opening 20 is oitslightly greater width.

than the extreme width of the latching lug 23 and accordingly by rotating the crank 13, the latching lug 23 will have its rear face 31 forced into engagement with the latch shoulder 30 causing the same to retreat against the action of its spring '32, the entire latch swinging about its pivot until the rear face 31 of the latch is engaged with the edge 34 of the opening 21. At this time if the crank be forced rearwardly, the latch lug will pass through the opening and the entire crank may be moved rearwardly to permit engagement of the starting head with the crank pin 18. The forward end of the latch 23 is reduced in width to a point where it will enter through the opening 21 and between adjacent edges 35 of the opening 21 and that formed by the shoulder 30 of the latch, this reduced end portion being connected with the rear face 31 by an inclined wall 36 operating as a wedging when the crank is moved forwardly to shift the latch 29 about its pivot against the action of its spring 32 and permit the lug to engage in the opening. This inclined shoulder or face forms also a ratchet face preventing sticking of the lug 23 in the opening 21 when the crank is rotated in a clockwise direction as it will be during starting of the engine and will thus prevent the starting crank from being brought to an abrupt stop in event it is forced outwardly by its spring 5 14 during a cranking operation. The front face 37 of the lug being straight will provide an efiicient stop when the crank is being aligned with the opening 21, it being necessary at this time to simply rotate the crank in a counter-clockwise direction and when the lug 23 aligns with the opening 21, the crank will be forced outwardly by the spring 14 and the face 39 of the lug 23 and will engage against the face 35 of the opening 21. The plate 20 must, of course, be secured against movement with relation to the crank case 11 and as a convenient means for securing the plate in such position I provide the plate with integrally formed forwardly extending arms 40, the forward extremities of which are adapted to rest upon the upper surface of the ears 42 of the bearing cap 43 of the bearing 10 and having openings through which the cap bolt 44 may extend. I

It will, of course, be obvious that the structure hereinbefore set forth is capable of a considerable range of change and modification without in any manner departing from the spirit of my invention and I accordingly do not limit myself to such specific structure except as hereinafter claimed.

7 I claim 1. In combination with a rotatable starting crank for engines, the starting crank being longitudinally shiftable to engage the crank shaft of the engine, a collar secured to the starting crank and having a latching lug provided with a rearwardly directed shoulder, a plate fixed with relation to the crank shaft and at the opposite side of the collar from the crank shaft, said plate having an opening through which the latching lug of the collar may extend and over one edge of which the shoulder of the latching lug may engage and means carried by the plate yieldably maintaining the latching lug with its shoulder so engaged.

2. In combination with a rotatable starting crank for engines, the starting crank be ing rotatably mounted in a bearing carried by the engine and longitudinally shiftable through said bearing for engagement with the crank shaft of the engine, coacting latch elements carried by the bearing and crank for latching said crank against longitudinal movement and out of engagement with the crank shaft of the engine.

3. In combination with a rotatable starting crank for engines, the starting crank being rotatably mounted in a bearing carried by the engine and longitudinally shiftable through said bearing for engagement with the crank shaft of the engine, coacting latch elements carried by the bearing and crank for latching said crank against longitudinal movement and out of engagement wit the crank shaft of the engine, including a latching lug carried by the crank, a plate fixed with relation to the bearing and in which the lug is engageable in the forward position of the crank and a yielding element maintaining the latch in engagement in the opening of the plate and from which the latch lug may be disengaged by predetermined operation of the crank.

4. In combination with a rotatable start-- ing crank for engines, the starting crank being longitudinally shiftable to engage the crank shaft of the engine, a collar secured to the starting'crank and having a latching lug provided with a rearwardly directed shoulder, a plate fixed with relation to the crank and at the opposite side of the collar from the crank shaft, the plate having an opening through which the may extend and means carried by the plate and engaging the latching lug when extended through said opening for forcing the latch lug to one side of the opening and thereby engaging said shoulder over one edge of the opening.

5.
