STAQRTEB FOR EXPLOSIY-ENGNES.
To all 'whowi 'it may concern: Y
Specification of Letters Patent. Application flled'ssptember 1,1903. Serial No. 171,645.
Patented Sept. :3, 1907.
l to, and reference can be made thereto for a full under- Be it known that I, JonN B. BARTHOLOMEW, aicitizen standing of one such set` of parts.
of the United States, residing `at Peoria, in the county of Peoria and State of-Illinois, have invented certain new and useful Improvements in Starters for Explosive- Engines, of which the following is a specification, reference being had therein to the accompanying drawing.
This invention relates to mechanism for starting explosiveengines, it being particularly Well adapted for Ait use in connectionl with the engines employed in automobiles'. v
It consists in providing what may be regarded as a friction clutch one element of which is connected with the engine and the other element of which is adapted to be actuated by manually controlled devices. With the .parts for accomplishing the starting of the engine, I
`also combine means for positively insuring that any reactionary movement of the engine shall not cause serious accident.
The several features of invention and advantage will be readily understood from thedrawings and description following.
Figure l is a view of a sufficient portion of'an automobile to illustrate the manner ofapplying the mechanism embodying my improvements. Fig. 2 is a side elevation of tle fly wheel of amengine provided with one of myimproved starting devices. Fig. 3 shows the fly wheel in vertical section and the starting devices in` lend elevation. Fig. 4 shows the rotary carrier detached.
Fig'. 5 is a vertical sectionthrough the shoe arm E.
It will be understood that my improved starting device can be used with or gasolene engines of different forms and with engines employed for different purposes than thatherein illustrated.
In order to show one way of applying my improvements, l have indicated in the drawings more-orleansconventionally an automobile 0r road vehicle propelled by a gasolene engine.
The body of the vehicle is indicated by l, 2 indicating i be constructed and arranged in any suitable manner, it
is not necessary to here describe them in detail.
In an earlier application for patentl which I` filed on.
.Tune 30, 1903, Serial No. 163,758, I have shown the full details of a mechanism such as is here generally alluded starting device forbringing the parts of the engine tov those positions where they willcommence automatically their desired movements, vthe description herein willbe restricted thereto.
5 indicates the fly wheel which is secured tothe crank shaft 4, this wheel meeting the usual requirements oa gas oroil engine. On one side its hub is made cylindrical, it being preferably trued up in a machine, if necessary, so that its periphery shall be concentric with the axis of tlie'shaft 4. On this hub there is placed a collar 7 fitted snugly thereto and ladapted to turn freely thereon. From this collar there extends outward radially an arm C.' arm there is pivoted aswinging lever carrying afriction shoe. The lever is indicated as a whole by4 G, it having an arm at E provided with a friction shoe-e which is arranged to engage with a concave surface at 8 formed on the fly wheel. `The lever G has also an arm D arranged at an angle to the shoe arm E.
d indicates a pivot which unites the friction lever with the rotary arm C. l
B is a draft link or pitman which is pivotally coni nected to the arm D. It extends upward and preferably at a forward inclination to a point in front of the drivers seat at 2.
A is a lever pivoted at a to a'suitable part of the car-- riage frame. It is approximately vertical in position or slightly inclined, and stands normally within easy reach of, an occupant of the carriage seat. When this seat is adaptedto hold two' riders, this lever is prefer'- ably'arranged in the f-vert'ical, longitudinal plane ofthe Y carriage at the middle partol the seat sothat it can be reached by either occupant.
H indicates part of the framework of the 'vehicle or of thesupport for the engine, and I utilize this frame as one element of a safety device adapted to disconnect A the-hand operated parts of'the starter from the engine in case therfly wheel should tend to rotate backward. I is an arm on the friction lever extending upward i beyond the pivot at d.
F isa stop, preferably a pin, seculfa'lu tothe frame,
21s, for instance, to the bar H. This pin is so situated lthat it canfbestruck bythe arm 'l as the latter movesl backward and when so struck it 'will cause the armto swing the friction shoe'ont of engagement with the fly wheel.
The mode ofeperation, and manner of using the devices which -Ihave described will be readily understood. When a rider occupying' the seat of the vehicle desires lo the outer end of this.
tol
. surface at 8 on the fly Wheel and to firmly engage 'eachiorward' throw of the lever.
therewith, and the next result, forward draft being l exerted by the lever A on the link B, is to cause the forward rotation loi the fly wheel. The parte are so related as to permit about oneaciith lof a revolution at The driver repeats this reciprocating movement until the fly wheel brings the'crank, and the latter brings the engine piston to the proper' place in thecycle tor the first explosion. When this explosion occursythe engine commences to revolve tlie'crank shaft and thereaiter the rotation oi the shaft continues automatically. ritter the engine has started,y the driver permits the lever A and link B to move backward far enough to permit the arm lv to impinge upon the stop F which thrusts and holds 'the friction shoe out of engagement with the wheel until it is again desired to start the wheel from rest. The wheel can revolve forward with safety even when the friction shoe isl in contact therewith, 'as the direction of its motion is such' that there will be no binding or locking, If at any time in starting the engine a premature explosion should occur tending to drivethe piston suddenly backward before it completes its movement toward the larger receiving end of the cylinder, the operator is saved from accident by-theparts at F and I. There may be a short backstroke of the lever A resulting YThe co-aating surfaces -of the fly wheel 'and of the sl'oe are smooth, with theresult that, while suicient seance LWhat I claim is:
1.. In a starting device for an internal combustion` eilgine, the combination of the .engine shaft, a ily wheel mounted thereon,l`1aving a friction surface, a rotary reciprocating friction shoe arranged to engage with the friction surface of the 'fly wheel when moved in one direction, and arranged to easily separate therefrom when moved in the opposite direction, means for moving the friction shoe bodily toward the y wheel to engage with and turn the latter forward or for moving it bodily away from the wheel to disengage the shoe, and automaticallyacting devices fordisengaging the sh'oe'from the ily wheel when it is carried backward, substantially as set forth.
2. In a. starting device for an internal combustionengine, the combination with the engine shaft andl a y wheel thereon, formed with a concave friction surface, of an arm free to turn 'about the axis of the shaft, a lever pivoted to the outer end of the said arm, a friction yshoe carried by the lever and arranged to engage with the friction surface of the tly wheel, and operating means for reciprocating the friction slioe, such means being connected with the said pivoted lever at a point between its pivot Hand theaxis of the fly wheel, whereby the shoe is brought into engagement with the fly wheel or is. disengaged therefrom in advance by a forward or backward movement of the said arm, substantially as set forth.
In testimony whereof I aii myv signature in presence of two witnesses.
