SAFETY ATTACHMENT FOR AIR-COOLED GAS-ENGINES.
Specification of Letters Patent.
Application filed March 18, 19 13.
Patented June 16, 1914.
Serial No. 755,216.
To all whom it may concern:
Be it known that I, MICHAEL J STANTON, citizen of the United States, residing at Shelton, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Safety Attachments for Air-Cooled Gas-Engines, of which the following is a specification.
This invention relates to safety attachments for air cooled gas engines and has as its object to provide means for automatically stopping the engine upon disarrangement of the driving mechanism for the fan.
It is a well known fact that such engines require almost constant attention inasmuch as should the belt which transmits power from the fly wheel to the fan shaft, break, the fan shaft will cease to rotate and the engine would soon become so heated as to render it unfit for further use.
In the accompanying drawings: Figure 1 is a view in elevation of the device applied to an air cooled gas engine; Fig. 2 is a perspective view of the mechanism removed. Fig. 3 is a detail view partly in elevation and partly in section of a portion of the mechanism. Fig. 1 is a View similar to Fig. 1 illustrating an arrangement of the device for use in connection with a battery switch. Fig. 5 is a view similar to Fig. 2 illustrating the location shown in Fig. 4.
In the drawings the engine is indicated in general by the numeral 1 and the crank casing by the numeral 2. The crank shaft is indicated at 3 and carries fly wheels one of which is indicated at 4. The engine cylinder is provided with a jacket 5 in which the fan is mounted, and the fan shaft is indicated at 6 and carries a small pulley 7. The belt 8 is trained over the pulley 7 and about the fly wheel 4 and serves to transmit power from the fly wheel to the fan shaft for the purpose of rapidly rotating the fan.
A standard 9 is secured as at 10 upon the engine casing 2 and carries at its upper end a pivot pin 11 supporting for rocking movement an arm 12 which extends transversely in rear of the engine, as clearly shown in Fig. 1 of the drawings, and has portions lying at opposite sides of the pivot 11. That end of the arm 12 which projects in the direction of the fly wheel 4 has mounted upon it a pulley 13 which rests upon the rear stretch of the belt 8 and is supported thereby, downward movement of this end of the arm being normally prevented. The other end of the arm 12 is provided with a portion 14. extending toward the engine cylinder and with a finger 15 which projects downwardly from the portion 14, as clearly shown in Fig. 2 of the drawings. A standard 1.6 is secured upon the crank casing 2 or upon any other suitably located portion of the engine, and projecting from the upper end of the stand ard 16 is a sleeve 17, the said sleeve extending beneath the portion 1 1 of the arm 12, as shown in said Fig. 2. Slidably mounted upon the sleeve 17 is a rod 18 carrying at one end a head 19 which rests against the lower end of the finger 15. A spring 20 is fitted upon the sleeve 17 and bears at one end against the upper end of the standard 16 and at its other end against the head 19, and this spring serves to normally hold the head 19 firmly against the said finger 15. At this point it will be understood that should the finger 15 be moved out of engagement with the head 19 the spring 20 will immediately force the said head and the rod 18 by which it is carried, forwardly.
In connection with the engine illustrated in Fig. 1 of the drawings, there is employed a magneto 21 the switch handle of which is indicated at 22, and this magneto is mounted upon the engine in such position that the handle will be located directly in the path of movement of the head 19 when the finger 15 is moved out of position for engagement by the said head. At this point it may be stated that the magneto is so positioned that in order to break the circuit the handle 22 is to be swung forwardly.
From the foregoing description of the invention, it will be understood that the arm 12 is normally held against rocking movement due to the fact that the pulley 13 is supported by the belt 8. Should this belt, however, break, the weight of the pulley would serve to swing that end of the arm by which it is carried, in a downward direction, thereby swinging the opposite ends upwardly and moving the finger 15 out of engagement with the head 19. Immediately upon disengagement of the said finger from the head, the spring 20 will force the head forwardly, striking the handle 22 and throwing the same in a forward direction, thereby stopping the engine. It will thus be apparent that an air cooled engine equipped with the safety appliance embodying the present invention willr'equire no attention so far as damage due to the breaking of the belt 8 is concerned.
It will of course be understood that the safety appliance herein described is not limited in its application to use in connection with the magneto switch but that a battery switch could equally as well be thrown thereby.
In that form of the invention shown in Figs. 4 and 5, the invention is adapted to operate a battery switch, this form of the invention being employed when a battery is used instead of a magneto. In the said figures the numeral 23 indicates a battery and 24 a switch. A wire or small rod is connected at its upper end to the switch lever and at its lower end is pivotally connected as at 26 to the rocking arm 12. In this form of the invention the standards 16 and the parts supported thereby are of course omitted.
What is claimed is:
1. In a mechanism of the class described, a belt supported pulley, an arm pivoted between its ends for rocking movement, and at one end carrying the said pulley a spring pressed plunger member, and a depending finger carried by the other end of the arm and projecting normally in the path oi movement of the plunger member whereby to normally restrain the said member.
2. In a mechanism of the class described, a belt supported pulley, an arm pivoted between its ends for rocking movement and at one end carrying the said pulley, a standard, a sleeve projecting from the standard, a plunger slidably fitted in the sleeve and having at one end a head normally resting against the outer end of the sleeve, a spring fitted upon the sleeve and bearing at one end against the standard and at the other end against the head of the plunger, and means carried at the other end of the said arm normally projecting in advance of the head of the plunger, whereby to restrain the same against movement against the action of the spring.
In testimony whereof I aliix my signature in presence of two witnesses.
