Application filed January 6,1905. Serial No. 239.918.

To ali/Z whom, t ntay concern:

Be it known that I, MAX MNZEL, engineer, a subject of the German Emperor, residing at Brunswick, Duchy of Brunswick, Empire of Germany, have invented certain nev.r and useful improvements in Automatic Cut-OHS for Explosive-Engines, of which the following is a specification.

This invention relates to automatic cutfor use in connection with explosive-motors or for other purposes wherein it is found applicable.

Primarily, the invention resides in providing an automatic cutoff in a manner as hereinafter referred to which is particularly adapted for closing the suction-pipe of an explosive-engine when the latter discontinuos its operation, thereby preventing the escape of gas. l

The invention further aims to provide an automatic cut-ofi which shall be simple in its construction, strong, durable, efficient in its use, and comparatively inexpensive to set up.

To this end 4the invention consists of the novel construction, combination, and arrangement of parts hereinafter more specifically described.,v illustrated in the. accompanying drawings, which formo. part of this specification, and particularly pointed out in the claims hereunto appended. y

ln the drawings, wherein like reference characters denote corresponding parts throughout the several views, Figure l is a side elevation of a (portion. of an air-suction pipe, showing the a aptationof a cut-oit in accordance with this invention. Fig. 2 is a sectional plan. Fig. 8 is aplan. Fig. 4 is a side elevation of amoditication; and Fig. 5 is a sectional eievation'cf an explosive-motor, showing a cut-oit in accordance with this invention arranged in operative relation with respect to the motor.

Referring to the drawings hy reference characters, a denotes an air-conduit or suction-pipe through which air is supplied to form the explosive charge or the gas mixture, and the said conduit d is closed when occasion requires hy the automatic cut-off now to he described. rihe automatic cut-oil' consists of a valve conduit d and carried hy a stem b, which is journaled for rotation in and projects laterally from each side of said conduit a. Upon one of the projecting ends of the stem t is Vmounted -a coiled tension-"spring g, which has one of its ends, as at g?, to a diskh, se-

c, arranged within said the lever d in the position to which it had cured to the outer end ofthe stern b, and has its other end, as at g3, fixed to the conduit a. The function of the spring ically close the valve c when the same is released in a manner as hereinafter referred to. The springv g is inclosed in a sleeve g4, which is carried by the disk h and disconnected from the conduit a.

' Upon the other projecting end of the stem b is loosely mounted a lever d, having its upper end enlarged and formed in a segmentshaped manner, as at 1", with the top edge rnl thereof formed with a recess o for a purpose to he hereinafter referred to. A second lever e is connected with the stem b in such a manner that the said lever c can move longitudinally upon the stein b as well as rotate said stem b when necessary. The lever` c is arranged in iront lof the lever d, and the said levers are clamped together upon the stem b so as to turn in unison when necessary by means of a wheel f, which is shiftableupon the stem I), so as to press the said levers together and clamp them against an abutment p upon the stem b. Fixed to the conduit a is a support i and to the top of which, as at 7c, is pivoted one end of a swinging lever Z. The other end of said lever lis attached to a holding-arm fm, which is adapted to engage in the recess o for preventing the lever d from being shifted by the action of the spring g. The arm m is moved into and out of the recess through the action of the governor m2 'upon a lever-arm m3, attached at one end to the arm m, Fig. 5.

The manner in which the cut-oi'f operates in connection with an explosive-motor is as follows: The valve c is adjusted to working position by the lever d and is then retained in such position by hand or by an optional stopping has operated to such an extent that the governor m2 causes the arm m to move downwardly into the recess o, and thereby retain the lever c from movement. The wheel f is then released, the valve c then vadjusted through the medium of the lever e, according to the requirements. The wheel f is then adjusted so as to clamp the levers d c to the stein b, the arm m in the meanwhile retaining been moved when adjusting the valve cy to working position, said arm m after the two levers have been clamped to the stem b continuing to retain the lever d in the position to which it. had been adjusted, and at the same g is to automatlongitudinally device (not shown) until the motorf IIO .two levers d e therewith and moving the are clamped together upon the stem b, the

j the arm mis moved out ofthe recess o. The

tors comprising the combination with. a suetime, owing to the fact that the two levers latter-is also prevented from movement until movement of the arm m out of the recess 0 is had when the motor is stopped, the stopping ofthe motor causing the governor m2 to rock the lever-arm m3, so that that end of the lever m3 which is connected with the arm m will be elevated, consequently shifting the arm ,m out of the recess 0 and permittingv the action of the spring g to turn the stem carrying the valve c to closing position. A scale r2 is arranged oii the segment-shaped portion r, so thatthe position to which the valve c is to be or has been ad'usted can be ascertained.

A modified orm of eut-ofi is shown in Fig. 4, and in which a denotes the conduit, c the valve, and b the stein. s denotes a vertically-movable rod connected at its lower end through the medium of the link t to the stein b. The rod s carries a weight g and also a sliding block g5, to which is ivotally connected, aszat g", a'lever d. he block g5 is adjusted through the medium of the screw Wheel e', mounted upon the upper end of the rod s. The lever g carries a trip-arm having a nose 0', which is adapted to abut against the lower end of the holding-arm m when the `said arm m is moved to a position in the path of the nose o through the action of the gov? ernor of the motor. The arm m is connected with the governor in. the same manner as the arm m.l The 'function of the weight g is to lower the rod s when the nose of the trip-arm r is released, owing to the action of the governor upon the arm m. The weight g is used instead of the spring g heretofore referred to. The adjustment of the valve c is caused through the operation of the wheel e.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is- I 1. An automatic cut-off for explosive-mtion-pipe, of a valve mounted therein, means for shifting the valve to openv position, means for retaining the valve iii. an open position, l

means for automatically returning the valve to closure position when released, and means foradjusting the'valve after the saine has been shifted to open position.

2. An automatic eut-off for eXplosive-motors, comprising a valve, means for shifting the valve to open position, meansfor retain^ for opening the valve, means for retaining the valve in an open position during the operation of the motor, means operated by the governor of the motor for moving said retaining means to and from operative position during lthe operation of the motor, and for moving said. retaining means to and holding it in inoperative position when the .motor diseon` tinues its operation, means 'for automatically returning the valve to closure position when said retaining means is moved to inoperative position, and means for adjusting the valve after the 'same has been moved to open position.

4. An automatic cut-ofi' 'for ex losivelengines comprising a valve, means or opening the valve, means for retaining the valve in an open position during the operation of the mtor, means operated by the governor of the motor for moving said retaining means to and from operative position when thernotor is started and for moving said retaining means to and holding it in inoperative position when the motor is stopped, and means for automatically returning the valve to closure position when released.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

MAX MUNZEL. Witnesses:
