CLARENCE O. HOWLAND, OF TOLEDO, OHIO, ASSIGNOR, BY MESNE ASSIGNMENTS, TO
THE ELECTRIC AUTO-LITE COMIPANY, OF TOLEDO,
OHIO, A CORPORATION OF OHIO.
ENGINE STARTER.
Application filed March 15, 1920.
To all whom it may concern:
Be it known that I, CLARENCE 0. How- LAND, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Engine Starters, of which I declare the following to be a full, clear, and exact description. 7
This invention relates to apparatus for starting internal combustion engines which, tostart, require the application of an external force.
An object of the invention is to provide a practical, durable and inexpensive apparatus for initially rotating the crank shaft of such an engine.
Another object is to provide a starting apparatus which during normal operation of the engine, shall be disconnected therefrom but which, when operated to start the engine, shall automatically connect with a moving part thereof.
. Afurther object is to provide an apparatus of this kind including a motor driven shaft which remains disconnected from that part of the apparatus cooperating directly with the engine except during the starting operation.
Further objects of this invention relate to economies of manufacture and details of construction as will hereinafter appear from the detailed description to follow. I accomplish the objects of my invention in one instance by the devices and means described in the following specification, but it is evident that the same may be varied widely Without departing from the scope of the invention as pointed out in the appended claims. Structures constituting certain embodiments of my invention, either one of which may be the preferred, are illustrated in the accompanying drawings forming a part thereof, in which:
Figure I is an elevation partly in section of the starter comprising my invention. Fig. II is a similar view showinga modified form.
In the drawings, the same reference numerals refer to similar parts throughout the several views.
Referring to Fig. I, an electric starting motor 5 is shown having a combined bracket and housing 6 which serves to support a bearing? for a shaft denoted as a whole by 8. This shaft 8 is shown as having an outer por- Serial No. 365,790.
The operation of this modified form being similar in all respects to that of the form already described, a detailed description of the same is deemed unnecessary and will therefor be omitted.
i It will thus be seen that I have provided an engine starting apparatus which is e11- tirely automatic in its operation requiring only the closing of the motor circuit and in which the pinion for engaging the fly-wheel wheel and from the motor shaft and supported from an external bearing.
Inasmuch as the invention herein disclosed is susceptible of various other embodiments and as various changes might be made in the embodiment set forth, it is to be understood that all matter described above or shown in the accompanying drawing is to be interpreted as illustrative only, and not in a limiting sense.
Having thus described my invention, what I. claim as new and desire to secure by Letters Patent, is 2- 1. In an engine starting mechanism the combination of a rotatable engine member, driving means therefor normally detached from said member, a drive shaft normally detached from said driving means and in axial alignment therewith and means constructed to be moved into engagement with said driving meansby the initial rotation of said shaft to transmit a driving torque from said shaft to said driving means.
2. In an engine starting mechanism, the combination-of a rotatable engine member, a motor driven shaft, a screw threaded driving means for said engine member, a. screw threaded member mounted on the end of said shaft adapted to engage said screw threaded driving means, and means for cansing said screw threaded member to move into engagement \Vllth said driving means upon initial rotation of said shaft.
In an engne starting mechanism, the combination of a rotatable engine member, a driving shaft, driving means for said engine member normally disconnected from and in axial alignment with said shaft and from said engine member, said shaft having means adapted to move longitudinally upon initial rotation to engage said driving means, said shaft means and said driving means having cooperating parts to cause said driving means to move axially into engagement with said engine member upon continued rotatlon of said motor shaft.
4. In an engine starting mechanism, the
combination of a rotatable engine member, a'
into engagement with said driving means upon sudden rotation of said motor shaft.
5. In an engine starting mechanism, the combination of a rotatable engine member, a driving mechanism therefor, mounted to be moved into and out'ofoperative connection with said engine member, a motor driven shaft, an inertia member mounted on said shaft, means connecting said inertia member and shaft for causing the former to advance toward said driving mechanism when said shaft is suddenly rotated, said inertia member and said driving mechanism having cooperating screw threaded portions normally disconnected but adapted to engage each other when the motor shaft is rotated. 6. In an engine starting mechanism, th combination of a rotatable engine member having teeth on its periphery, an electric moother, the construction being such that upon 10 tor for starting said engine having a bracket sudden rotation of said motor shaft, the forming a bearing, a shaft mounted in said sleeve is caused to move axially into engagebearing, a pinion carried by said shaft, a ment with, and to thread upon the pinion sleeve mounted on the shaft of said motor shaft to move the pinion into mesh with and having a pin and slot connection thereteeth on the engine member to start the en- 15 with, said sleeve and said shaft being in gine.
