Description
EMIL HARTUNG, OF DENVER, COLORADO.
CUT-OFF AND GOVERNOR.
SPECIFICATION forming part of Letters Patent No. 397,361, dated February 5, 1889'.
Application filed June 26, 1888. Serial No. 278,233. (No model.)
To (all whom it may concern:
Be it known that I, EMIL IIARTUNG, a citizen of the United States, residing at Denver, in the county of Arapahoe and State of 0010- rado, have invented a new and useful Improvement in Combined Cut-Offs and Governors, more especially the Tremper eom bined cut-off and governor, of whichthe following is a specification.
The object of my improvement is to stop the engine or keep it under control and not let it speed up to a speed which frequently causes destruction and loss of lives and property when the belt driving the governor breaks or slips or the governor does not work from any other reason. This object I attain by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a side view of the 'lrempercombined eut-ott and governor with my improvement attached to it. Fig. 2 is a part of said governor, showing the lifters with thumbs, also the lifting-block and cone in correct position to st op the engine. Fig. 3 is a section of Fig. 2 on line 1 and 2. Figs. 4 and 5 are details of the thumb-rod.
Similar letters refer to similar parts th roughout the several figures.
The operation of the Tremper combined eut-ott' and governor is as follows: The rockrod A, being attached to the slide-valve rod, imparts a rocking movement to the bell-crank B, which moves the lifters U and D upward and downward alternately a given distance.
The hardened-steel plates E and F, fitted into the lifters, project so far as to engage with the corresponding plates, G and H, in the liftingbloek I. \Yhen the cone K is raised to its full height by the governor-ball L, the lifters will carry the lifting-block upward, opening the cut-off valve, which is fastened to the stem M, and as the steel plates (eitherE and Gor II and F) .under these circumstances remain in contact the cut-off valve remains open until it is closed by the lifter on its dmvnward movement. It is then reopened by the lifter on the opposite side, which represents thereturn-stroke of the piston. In this condition the engine is taking steam full stroke. If a less amount of steam is sufficient to maintain the speed of the engine, the cone K is moved downward by the operation of the governorballs N and O, and the lifter, sliding outward as it moves upward, is disengaged from the lifting-block I, and the cut-off Valve on the stem M is allowed to drop instantly into its seat, cutting off the passage of steam into the cylinder. In this condition the engine is working steam expansion.
The operation of myimprovementis as follows: Before stopping the machine the ring W' is swung over the head R on rod Q, inorder to have the engine in readiness for starting. This position will enable lifters to operate eut-olt' valve, when engine is started, as before described. When the engine is at rest, the tlmmb-rod Q is kept down in its lowest position by the ring \V being swung over head R, which then rests on governor-:t'rame S. In this position. the small roller V, which is fastened to the lower end of rod Q, as shown in Fig. 5, is kept far enough below the two thumbs X and Z (parts of lifters O and D, as shown in Fig. 2) to enable the lifters C and D to engage with the steel plates G and H on beater I. Under these circumstai'ices when starting engine the litters will raise the cutoff valve and allow the steam to pass into the cylinder of the engine and the engine will be running. When up to full speed, the ring \V is swung off head R, and as the lever P has swung downward in the slot T of rod Q, as shown in Fig. 4, rod Q will be kept down by its own weight. Now it anything happens either to the governor or the belting, the governor-balls O and N coming to rest, raising cone K, lever P must swing upward, raising at the same time thumb-rod Q, (in point The small roller V, fastened to lower end of rod Q, engages at once with thumbs X and Z, as shown in Fig. 2, which serve as levers to throw out the litters and in turn keep the lifters C and I) far enough from beater I to prevent the steel plates IE and F from engaging with G and If; consequently the cut-off valve must remain on its seat, no steam can pass into the eylimler, and the engine stops. Rod Q is adjusted to the requisite length by screwing its IOO moving lifters C and I) and liftii'igdiloek I, of levers or thumbs connected with said lifters and means automatically brought into play on derangement of governor or belting to act on said levers to throw the litters away from the beater, so as not to ei'lgage therewith in the movement of the stem carryin the beater, substantially as and tor the purposes set forth.
2. The combination, with the alternately moving lili'tcrs C and .l) and liftiugbloek l, of levers or thumbs X and. Z, eonneeted with said lifters, a reciprocating rod constructed to engage with said levers or thumbs, and means for automatically moving said rod on derangement of governor or belting to engage with said levers to throw the lifters away from the beater, so as not to engage therewith in the movement of the stem carrying the beater,
substantially as and for the purposes set lorth.
3. The (mmbination, with the altornatclymoving lil'ters t and I) and lifting-block l, of
levers or thumbs X and Z, couneeted. with said 2 lifters, a reciprocating rod constructed to en- 1 gage with said levers or thumbs, means for holding said rod out of engagement with said levers or thumbs, and means forautomatieally moving said rod on derangement ol governor or belting to engage with said lovers to throw the lifters away from the beater, so as not to engage therewith in the movement of the stem ez'trrying the beater, substantially as and for the purposes set forth.
4. The combination, with the beater I, lifters C l), and lever 1, of the levers or thumbs X and Z, connected with said lifters, a rod constructed to engage with said levers or thumbs, when moved in line therewith, to throw said lifters out of line with said heater, an d adapted to have said lever P engaged with it to bring it to bear against said thumbs, and a locking device, \V, to hold said rod out of engagement with said thumbs while the engine is being started, said rod being free to be moved by said lever P after the engine is started, whereby the engine may be automatically stopped, should the necessity therefor arise, substantially as set forth.
