Application filed March 25, 1903. Serial No. 149,570. (No model.)
' To all whom it may concern:
Be it known that I, CLARENCE N. 0001:, a citizen of the United States, residing at Mu n-V gen, inthe county of \Vood and State of Ohio, have invented certain new and useful Improvements in Starting Mechanism for Explosive-Engines, of which the following is a specification,
Considerable difficulty has been experieucedin starting engines ofthe explosive type, and it often happens that valuable time has been consumed and much trouble and annoyance occasioned before the desired result has been attained. a
To overcome these objectionable features and others attendant upon the use of engines of the type aforesaid are the primal objects of this invention.
In accordance with this invention an ex-' plosive, such as gunpowder, is utilized for firing the first gaseousmixture in the cylinder and at the same time imparting the initial movement to the piston, whereby the momentum of the fly-wheel is sufficient to return the parts to proper position for opera-.
tion by explosion of the second charge by the electric spark or other igniting means commonly employed in engines of this type.
For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and drawings hereto attached.
While the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of an explosive engine equipped with starting mechanism embodying the invention. Fig. 2 is a section of the starting mechanism on the line X X of Fig. 1, on a larger scale, showing the relation of the crank to the trip-bar for releasing the firing-pin. Fig. 3 is adetail perspective view of the explosion-barrel and adjunetive parts. Fig. 4 is a vertical central section of the explosion-barrel, means for setting off the percussion-cap, firing-pin, guide therefor, and trip-bar. Fig. 5 is a perspective-view of the lower portion pf the guide for the firing-pin.
Fig. 6 is a perspective view of the trip-bar and operating-crank. V 1
Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.
The engine illustrated is of common con str'uction, being shown Ito demonstrate the workings of the invention. The explosionbarrel 1 is of substantial formation to with- .stand the internal pressure resulting from setting off an explosive, such as gunpowder. The explosion-barrel is threaded at oneend to make firm connection with the head 2 of the engine-cylinder and is in 00 m unication with the latter to admit of the ash igniting and efiectingexplosion of the gaseous mixture, by means of which the engine is operated. The explosion-barrel is constructed for reception of a wrench or spanner, whereby same may be fitted to or removed from the enginecylinder at will, and, as-shown, the barrel is flattened at opposite sides, as indicated at 3.
The bore 4 of the barrel communicates with a lateral opening internally threaded to receive coupling 5, provided at its outer end with nipple 6 for reception of the percussion cap, whereby the explosive is supplied to the barrel when starting the engine. A bonnet 7 is fitted to the outer end of coupling 5 and forms a housing for nipple 6 and serves to confine the force of the explosion. The hammer 8 for striking the percussion-cap is mounted in the upper end of bonnet 7 and is directed in its movements thereby and is held at the l'nnit'of its upward movement by coilspring 9, mounted upon its stem and confined between bonnet 7 and stop 10, fitted to the upper threaded end of the hammer-stem.
Bonnet 7 may be readily disconnected from the upper threadedend of coupling..5, and opposite sides are-fiattenedfdr reception of a Wrench or spanner for this purpose. Coupling 5 is provided intermediate of its ends with flange or collar 11, which constitutes a stop and is flattened at opposite points for reception of a tool to admit of tightening or loosening said coupling, as may be desired.
The guide 12 for reception of firing-pin 13 is tubular and consists, preferably, of a section of pipe adapted to be fitted at its lower end to bonnet 7 and collar 11, whereby it is held in place. A transverse slot 14 is formed in a side of guide 12 a distance above the hammer 8 to provide sufficient fall for firingpin 13 in order to insure explosion of the percussion-cap applied to nipple 6. The firingpin 13 consists of a heavy bar loosely fitted in the upper portion of guide 12 and normally supported by trip-bar 15, which has a portion entering slot-'14 a distance to support the fi-ring-pin. The trip-bar 15 is supportedin any suitable manner, preferablyby keepers 16 applied to the engine-cylinder and forming guides to direct the trip-bar in its movements and hold same in place. The outer end of the trip-bar is bent about at a right-angle, as shown at 17, to enter slot 14 and support firing-pin 13. The rear end of trip-bar has ver-.
t'icalextension 18, extended within the path of the projection 19 of thecrank-shaft 19, to which the balance or fly wheel 20 is secured. The engine is primed for starting by supplying explosion-barrel 4 with a charge of gunpowder or other explosive, same being supplied to the barrel either by removing the 'lattrfrom the engine-cylinder or by discon necting coupling 5 therefrom and placing the. charge in position through the side openingin communication with the bore of the barrel.
The percussion-cap is fitted to nipple 6 by removing bonnet 7, the latter being replaced in order to confine the gas resulting from the,
explosion. The firing-pin is supported within the upper-part of guide 12 by'the bent end 17 of trip-bar 15. The fly-wheel 20 is turned to draw a charge or carbureted' air or otherv driving thepiston forward with a. force to overcome the inertia of the'parts and impart a momentum to the fly-wheel snflicient to keep. the engine in motion, provided the igniterand-= means for supplying carbureted or explosive a percussive igniter, a bonnet inclosing the percussive igniter, a tubular guide fitted to said bonnet and suppdrted thereby, a firing pin located within said guide and directed in its movements thereby, and a tripbar coopcrating with the tubular guide for supporting the firing-pin and adapted to be operated by a moving part of the engine to efiect'a release o'fthe firing-pin at the flatly as set forth.
