STARTER FOR INTERNAL-COMBUSTION ENGINES.
Application filed December 17, 1914. Serial No. 877,8315.
To all whom it may concern:
Beit known that we, EDWARD J 2 THURBER, a citizen of the United States of America, residing in New Orleans, parish of Orleans, State of Louisiana, and JOHN W. RACK- LYEFT, a citizen of the United States of America, residing at Detroit, county of Wayne, and State of. Michigan, have invented certain new and useful Improvements in Starters for Internal-Combustion Engines, of which the following is a specification, reference beinghad therein to the accompanying drawings. v
The invention relates to starters for internal combustion engines and more particularly to rotary starters of the type actuated by a compressed fluid.
The invention has among the objects thereof to provide a simple and efficient starting mechanism; to provide a starting mechanism that is compactly arranged and comparatively light, so that the apparatus will not take up any unnecessary room or add much' weight to the engine. Further to provide an apparatus in which the parts are compactly arranged within the casing so as to form a single unitary structure for attaching to or detaching from the engine.
Other objects of the invention will more fully hereinafter appear.-
The invention resides in the peculiar construction, arrangement and combination of parts as hereinafter set forth and as particularly pointed out in the claims.
In the drawings,Figure, 1 is a central vertical longitudinal section of 'a starting mechanism embodying the invention; Fig. 2 is a section on the line 6 -6 of Fig. 1 with certain parts broken away; Fig. 3 isa section on the line 3-3 of Fig. 1; Fig. 4 is a section on the line 44 of Fig. 1; Fig. 5 is a section on the line 5-5 of Fig. 1.
The invention is primarily designed for use on automobile and marine engines of the explosion or combustion type, and generically embodies in a compact structure a fluid-operated rotary motor, a transmission. mechanism and other suitable elements.
Referring to the one embodiment of the inventionshown in the drawings, 1 desig-, nates thecasing, divided by aweb or partitioni;-2: into two chambers. Within one of the chambersis arranged a rotary motor, while of a clutch.
in the opposite chamber is arranged the transmission and clutch mechanism. In the structure illustrated, the casing upon one side of the web is provided with an annular rim 3' that is disposed eccentric with rela tion to the shaft bearing 4 in the web, while connected to the outer edge of'the rim 3 as by screws 5 is a cap'plate 6, the latter forming with the rim 3 and the web 2 a chamber for the rotor. The inner peripheral wall6 of this chamber-as will be noted upon reference to Figs. 1 and 3-'is eccentric to the Patented May so, rat a shaft bearing 4. The rotor consists ofa web 7 having an inwardly-extending flange 8 arranged concentric to the hub 9 of the web 7. J
I 10 are the blades ofthe rotor, three being herein shown, which are arranged for longitudinal movement in, slots 11 in the web 7 and flange 8.- The latter and theblades 10 are of a width to nicely fit between the ,web 2 and plate 6. As shown in Fig. 1, the blades are provided adjacent their lower ends with .cut away portions 12 which are adapted to engage a ring 13 arranged to travel within an annular guide groove 14 in the flange 8. This ring is free and acts as a .means for causing the blades. to move outto be reciprocated longitudinally, as will be readily understood. During the rotation of the motor the sleeve 16 will turn therewith.
The, transmission inechanismis herein shown as of the naled upon. stub or rim gear 21. The latter is carried by a disk 22 which is connected by means of screws 23 to a member 24 that forms a part 25 is the other clutch member which is keyed to a shaft 26 that is free to rotate in the sleeve 16.
28 are spring-pressed dogs which in one if planetary type. Thus jourshafts 19 are pinions 20, which are in constant mesh with an internal direction of rotation of the'member 24, are adapted to lock said member to the member 25, while in the opposite direction of rotation will disconnect the members 24 and 25.
As shown in Fig. 1 the sleeve 16 is provided with a portion that projects within the transmission mechanism housing, and this portion of the sleeve is provided with a pinion 29 that meshes with the pinions 20.
, 30 is a shaft journaled in a bearing-31 and fixedto rotate with the shaft 26, the shaft 30 in effect forming a continuation of the member 26.
The transmission mechanism chamber is closed by a cap memer 32 that is connected by means of screws 33 to the edge 34 of an annular flange 35 extendinglaterally from the web 2 and concentric with the bearing 4. The cap 32 is provided with a recessed or chambered portion 36 within which is arranged the clutch mechanism and this cap carries at its outer end the bearing 31. Detach'a-bly connected to the cap of the rotor chamber is a pump housing 37 within which is arranged a pump 38, the pump housing being attached to the cap by means of bolts 39. As shown, the end of the driven shaft has a portion 40 projecting within the pump housing and splined orotherwise' suitably connected to a sleeve 41 journaled adjacent itsouter end in a bearing 42. The pump. is provided with an eccentric 43 having a bearing 44 journaled upon the sleeve 41' and the latter and the bearing 44 are adapted to be coupled together by means of aclutch member 45 free to slide upon the sleeve 41 but secured thereto against rotation, and
having teeth 46 adapted to engage teeth 47 on the bearing 44. As the detailed construc-' tion of the pump mechanism does not form a part of the invention of this application,
'a description thereof will not be given. The
outer end of the pump casing is closed by -means of a cover plate 48'andpreferably the outer end of the sleeve 41 is provided with a crank-engaging. portion 49 for receiving the usual starting crank in case the rotary starter becomes inoperative. Normally the crank-engaging portion 49 is inclosed by means of a cap 50. As before stated, the sleeve or driving shaft 16 is journaled' in a bearing carried by the web or partition 2. This bearing in the structure illustrated projects laterally from. the partition into the chamber. of the rotor, this being permitted by the cut-away portions of the plates or pistons. As shown.
' in Fig. 1, the openings between the several chambers in the casing are all suitably sealed by packing material.
In operation, assuming that the portion 30 is fixedly connected to the engine shaft when compressed air or other compressed fluid is admitted into the rotor chamber, the rotor is started in motion, which turns the through the latter, the crank shaft. When the engine is started the speed of rotation of the shaft 30 is greater than that of the drive shaft 16, which causes the dogs to allow the member 24 to be disconnected from the member 25.
The pump is employed for storing compressed air in a tank or other chamber, as will be readily understood, and normally is disconnected from the shaft 26. During the operation of the engine, when'it is desired to add compressed air to the tank the clutch member 45 is longitudinally shifted through the medium of a lever 51, to cause the pump to be coupled to the sleeve 41 that is splined to the shafts 26.
From the foregoing description it will be readily understood that a starting mechanism embodying the invention forms a very compact structure and a complete unit in itself, the unit being arranged within a single casing. However, for certain uses the pump may not be employed, and we consider the invention to be of suiiicient scope to embodya starting unit having but the rotor and the transmission mechanism.
While a novel and very efficient construction has been shownand described, we do not desire to limit the protection to the one embodiment of the invention illustrated, but
consider the invention to be of sufficient scope to embody various modifications.
