STARTING DEVICE FOR INTERNAL-COMBUSTION ENGINES.

To all whom tt 'may conca'ng Be 1t known that I, HAROLD B. ANDERSON,

a citizen yof the AUnited States, residing at. Lakewood, in the county of Cuyahogazand 5- State of Ohio, lhave invented acertain new and useful Improve-ment in Starting De vices for Internal-Combustion Engines, ot whichthe following is a full, clear, and exact description, reference being had to the ac-' companying drawings.

This invent'on. relates to' starting devicesv for internal combustion engines, whereby the operation of the engine can be commenced without the usual laborious crank# Such mechanism may be divided intoy three generic types: first, those in which the l lng.

. operation of the engine is confimencedv by the unwinding of a spring in which poten--v tialA energy has been stored during the pre- 2C in which the operation of the engine is begun by means of the admission to thecylinders in proper order of compressed, gas. of

. some sort stored i-n a suit-able receptacle;.

and, third, those inwhichthe operation of the engine iscommenced bymeans of 'the vexplosionain the cylinders of a charge of gas introduced therein either prior to the stopping of the engine at its' previous operation.

or in some other manner. v y

Itis, of course, a well known fact that an engine will sometimes start from the spark by reason of an explosive gasolene mixture remaining in the -cylinders 'from the previous operation, but this operation is uncertain and unreliable', owing tode-terioration and l akage vof gasolene mixture'.

to my invention disclosed herein, for the purpose of supplying acetylene mixed with air to the engine cylinders, but most of these devices have been complicated and expensive, prone to leakage, and unrehable in operation.

The object of this invention is, therefore,

Application mea May 1,1912. serial No. 694,390.

the provision of new and improvedl devices for admitting'acetylene mixed with air iny `the right proportions tothe cylinder' of an explosive engine for the purpose of starting the same, the chief points of superiority of the present device over previous devices being those of simplicity, economy, reliability, freedom from leakage, and cheapness of manufacture. l

-This invention also relates to a connect-ion whereby a. radial handle, arm, or pointer may be adjustably secured to a rotatable shaft, stem, or spindle, and hasparticular reference to a connect-ion whereby the handle of a valve may be secured to its stem or a pointer secured to a valve stem or other rotatable member in such fashion as always` to register correctlywith the dial graduations with which it coperates. -Many differentexpedients have heretoforebeenelnployedfor this purpose but the same have been deficient either in failing to permitrelative adjustment or in not securing the parts tightly in place, the result being that upon t-he wearing of the valve parts or the slipping of the handle `on the stem the' pointer would fail to accord properly with its scale. It is also a well known fact that the usual method of securing the hand or pointer of an indicator to its spindle is very clumsy and inefficient, '.theresult. being that the hand frequently becomes displaced and indicates an'improper reading. It is also frequently the case that the handleof a valve is called upon to effectsome secondary result at a given point in the opening or closing of its valve, such as to make or break an lelectrical connection ordto operate arelated valve, and this necessitates an adjustable connection between the handle and valve stem so that the secondary action will take placey at a fixed time with respect to view through my improve'd starting device showing my improved connection associated therewith; Fi 2 isa right hand end view i..

of the sall i 3 is a bottom plan-view of the valve hand e; Fig. 4 represents'a-side' elevation cfa valve ofsl'ightly different type equipped vvith .my improved connection;

Fig. is an edge vievsT of an indicator dial showing the application of my connection to the pointer or hand; 'and F ig. 6 is an inside face view ofthe Washer which forms an essential part of improvedfonnection.

Describing the -parts by reference char-` acters, particular attention being 4given t0 Figs. 1 to 8, 1 represents'a valvecasing having a-suitable aperture into'which is threaded a stem 2, and to the outer end of this stern is secured a' handle 3 provided with a pointer- 4 movable4 over a scale 5. 4`The particular valve shown in Fig. 1 has a needle pointv' valve 'casing being here shown `as mounted upon a dash' boardll. '..Thepassageway 9 is intersectedby a recess 12 having an axial extension 13 parallel to the lstem 2, said extension communicating with the outer air through a port' 14. Seated upon a shoulder between the recess and 'its extension is a spring-pressed valve 15 having -a stem 16 extending through the plate 5 adjacent to the stem 2, theouter end of the stem 1 6 preferably being rounded:-

.The valve handle 3 is formed with a hub 17 having a substantiallyiiat bottom surface which is provided at one point with an arcuate recess'18 adapted to receive the end of thestem 16 to permit the valve 15 to be seated by its spring. The Vposition of 'the recess 18 is such as to cause the valve 15 to assume its closed positionat the time when' the pointer 4 points toward the oit or zero position of the dial, and the adjustment between the valve handle, and the stem 2 is such as to cause the valve needle 6 to be exactly seated at this time, this adjustment being'preferably accomplished by means of the connection now to be described.

In order to secure the handle to the valve 'stem the hub vthereof is internally threaded so as to' be screwed adjustably thereon, vthe outer face of the hub being .formed with radial serrations 20. An annular washer 21 is then slipped over the end of the stem so as to engage the hub, the inner face of said Washer being formed with serrations 22 engaging the serrations 20, said Washer-also having an inwardly projecting finger 23 engaging a longitudinal slot 24 formed in the end of the valve stem. The washer is pressed into engagement With'the hubby means'of a nut 25. f The operation of the engine is stopped by preventing the ignition of the charges in the -to be about right for the vparticular engine I engine stop's, the valve handle is returned to mixture. also be employed for continued operation of nut 25 being employed as in' the preceding cylinders as by opening the sparking circuit, and as 'the speed of the engine decreases, the handle 3 is shifted so as to open the valve by an amount found by former experience with which thestarter is used. This movement of the valve handle opens the passage through the conduit 8 by an amount necessary to deliver the proper quantity of acetylene 'and at .the same time forces the Valve 75 stem 16 inwardly s o as to admit air through the port 14to mix with the acetylene, the mixture of-the two gases being drawn into the cylinders by' suction. As soon `as the off position, thus ,closing the needle valve 6 80 and permitting the re-seating ofthe air valve 15 by its spring. The recess 18 ismade of `elongated shape in order to avoid the necessity of bringing the handle'back to an exact fixed position.' Theobject of using the valve '15 is to prevent air from being drawn through the conduit 10 into the manifold of the' engine durin its normal operation by gasolene, since t e air so admitted would tend to disturb the proportions ofthe fuel My improved starting device can the engine in A'case the gasolene supply becomes exhausted.

The valve illustrated in Fig. 4 is of much 95 *the same type. as that shown in Fig. 1 and comprises a casing 1 a having conduits 8 and 9 securedthereto and providedwitha simil f lar threaded stem 2. The remaining arts '100 are the same as those above illustrate and described and are similarly numbered the sole diilerencc `beingin the omissionoi the i air inlet valve together with its stem and` the corresponding omission of the recess 18. '105 In this instance the sole object of the adjust-A ment of the handle is to cause they pointer 4 thereof to register correctly with the 'graduations ofthe scale 5. This valve may bey employed either for the lamps or the starting mechanism of an automobile or for -any other location where a valve is desired.

When used as .an engine starter, undiluted gas is delivered by the conduit 10 to the intake manifold as before, the necessary air being admitted through the usual throttle.

In Fig. 5 I have illustrated the application of my improved connection to an indicator vor gage dial, the same comprising a scale 5,

a spindle or arbor 2a and a handle 4, said 120 handle havin a hub 18a threaded -upon the spindle 'or ar or and provided with serrations 20 on its outer face, the washer 21 and instance.

It will be understood that many changesl in details of construction and arrangement of parts can be made in my improved starter without sacrificing the advantages thereof or departing from the scope of my inven- 130 tion. It will also be understood that the uses and embodiments of the connection disclosed herein are illustrative 'merely and eating pointer is. to be connected to a spindle or arbor, Whether that rotating member be t-he stem of the valve or other device, or whether that spindle be a part of a gage,

y clock, speed indicator, compass, or the like'.
