APPARATUS FOR STOPPlNG STEAWl=ENGlhitZ-.
EPECIFICATIOH forming part of Letters Patent No, 31%,466, dated March 2%, 1885.
Application filed July 14, 15 84. (No model.) Patented in Bvlgium July 2, 1884. No. (55,063; in England July 2, 1984, No. 9,692, and in Austria-Hungary Oc'nher 7, 1884, No. 25,284 and No. 45,779.
To all whom it may concern.-
Be it known that I, HERRMANN OnLnn'r, a subject of the King of Prussia, residing at Vippes, near Gologne on-the lthine, have invented certain new and useful Improvements in Apparatus for Stopping Steam-Engines, (for which I have obtained Letters Patent in Belgium, No. 65,663, dated July 2, 188i; in Great Britain, No.9.692, dated July 2, 1854., and in Austria-Hungary.No. 25, 284C and No.45,779, dated October 7, 1884;) and I do hereby declare the following to be a full, clear, and exact description of the in vention,such as wi 11 enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters or figures of reference marked thereon, which form a partof this specification.
Accidents frequently happen in factories or machine-shops or other works by employs being caught by some part of a machineand either seriously injured or killed outright for want of means to instantaneously arrest the movement of the prime motor and thereby that of the driven mechanism.
The object of this invention is to provide means whereby the movement of the prime motor from which machinery is driven may be instantaneously arrested from any desired point of the shop, factory, or works; and said invention consists in the construction and rangement of mechanism for stopping the prime motor by uncoupling the slide-valve rod from the eccentric-rod from a point or points located at any desired distance from the engine, substantially as hereinafter fully described, and as shown in the accompanying drawings, in which Figures 1 and 3 are side elevations of so much of a vertical and horizontal engine, respectively, as is necessary to illustrate myinvention. Figs. 2 and 4 are top plan views of Figs. 1 and 3, respectively. Figs. 5 and 6are detail views. s
In the drawings, F indicates the frame or stationary portion of the engine, (J the valve chest, S, Figs. 3 and a, the driving or eccentrio shaft, E the eccentric, It the eccentricrod, and R the slide-valve rod, these parts being constructed and arranged as is usual in vertical or horizontal engines, except that instead of permanently connecting or coupling the rods It R, as is customary, I connect these in such a mannerthat they may be uncoupled instantaneously. To this end either of said rods may be provided with a fork, 1*, while the other carries a coupling-pin, r, which is or may be rigidly connected thereto or form part thereof, as desired. In Figs. 1 and 2 I have shown the valverod B as provided with the fork r,and the eccentric-rod R as provided with the coupling-pin r passing through the jaws of its forked end r, while in Figs. 3 and 4 I have shown the arrangement reversed. In either case the fork r is formed at right an gles to the fork r. The uncoupling of the valve and eccentric rods can, therefore, be readily effected by moving the eccentric-rod laterally, as in the case ofa vertical engine, or vertically, as in the case of a horizontal engine, as shown in Figs. 1 and 3, the valverod, owing to its guides, not being able to follow such lateral movement. To this end I employ a two-armed lever, L, pivoted to a stationary portion of the engine. In Figs. 1i and 2 I have shown the lever pivoted to the frame F of the engine, and in Figs. 3 and 4. to astand ard, K, secured to the bed-plate P of the engine. The outer end of the long arm Z of the lever L is held in its normal position (when the rods It It are coupled) by the arm a of a bell-crank lever, A, said arm having a suitable notch in its upper end, in which the end ofthe long arm Z of lever L rests. The short arm Z of lever L is pivoted to a connectingrod, B, that is connected with the couplingpin of the eccentricrod It, the outer end of which is forked, as shown at r in Fig. 5, or said rod may be connected in any other suit able manner with the outer end of the eccentric-rod B. When the rods are coupled, as shown in Fig. 1, the fork r of the valve-rod passes through the fork r of the eccentric-rod and embraces the pin 1*, as more plainly shown in Fig. 5. \Vhen, however, the long arm Zof the lever L is released by tripping the bellcrank lever A, the arms of said lever will assume the position shown in dotted lines, and the cocentric-rod and coupling-pin 1' will be moved laterally out of engagement with the fork r of the valve-rod 1%.
Instead of a fork, r, one of the rods may be slitted or recessed at its outer end for the reception of the coupling-pin secured to the outer end of the other rod.
Itis obvious that the lever Aniay be tripped in various Ways and from any desired point or points located at any distance from the engine. For instance, the arm a of the bellcrank lever may be connected by a cord, 0, &c., running over a pulley, 19, from the engineroom to the works, shop, or factory, and there branched out, as at b, to the desired localities as, for instance, in proximity to certain machinery where accidents are liable to occur.
By pulling upon any one of said connections the arm a of lever A will be moved toward the arm lof lever L, while that a will be moved away from said arm, and the lever L will be free to rotate on its pivot and uncouple the rods R R, as described. The cord or wire, &c., may also be connected directly with the arm a and that a dispensed with, as will be readily understood.
Itis obvious that instead of the bellcrank lever a sliding bolt may be employed to trip the lever L.
When the devices are applied to a horizontal engine in which the eccentric-rod is to be moved vertically, the short arm Z of the lever L preferably carries a grooved roller, D, in the groove of which rests the eccentriorod R, as shown in Figs. 3 and 4, the operation of tripping the lever being the samea-s above described; but to enable the short arm Z to lift the eccentric-rod out of engagement with the valve-rod, the long arm Z of the lever carries an adjustable weight, WV, as shown.
The movement of the lever in one direction may be limited, if desired, by a third arm, 1?, Fig. 1, coming in contact with some stationary part of the engine, as in Fig. 1.
To insure the tripping of the lever L, Fig. 1, I attach to its upper face a spring, S, the free end of which bears against a projection on the frame of the engine or other suitable stationary part, and to prevent the accidental tripping of said lever I provide a spring, 8, Fig. 1, that holds the arm a of the bell-crank lever A in engagement with the arm Zof lever L.
To avoid the effects of the shock on the release of the lever L when its long arm l is weighted, as in Figs. 2 and 3, I provide an elastic buffer, G, as shown in Fig. 3."
The coupling of the rods may be eiiected in various ways. In Fig. l I have shown a rackbar, R connected with the valve-rod R, with which meshes a pinion adapted to be rotated by a lever, I, to lift or depress the valve-rod, as may be necessary to couple the fork r thereof to the pin r of the eccentric-rod. For like purposes in horizontal engines the coupling pin r has anextension, T and in proximity to or within range of the pin is arranged a lug or pivot, h, secured to a standard, H, by applying a forked hand-lever, h, to the pivot h and, placing the same against the extension r of the pin r, the rod B may be moved forward or backward to bring the pin in position for coupling with the fork r of the eccentric-rod.
It will be seen that the stopping of an engine may be effected almost instantaneously, and by means which are at once simple and inexpensive, and that in case of a backward movement of the piston the steam will act as a brake to its further movement.
Having now described my invention, what I claim, and desire to secure by Letters Patent, 7 is 1. The herein described mechanism for stopping steam-engines, which consists in the combination, with the slide-valve and the cocentric-rods R R, detachably connected to gether, and the driving or eccentric shaft S, of a two-armed lever, L, and a tripping-lever operating to, trip the lever L, and through the latter disconnect the rods It It, for the purposes stated.
2. The herein described mechanism for stopping steam-engines, which consists in the combination, with the valve and eccentric rods R R, detachably connected together, and the eccentric-shaft S, of a twoarmed loaded lever, L, and a tripping-lever, A, operating to trip the lever L, and through the latter disconnect the rods R R, for the purposes specified.
3. The combination, with the slide-valve and connecting-rods R R, detachably connccted together, and the eccentric-shaft S of a steam-engine, of a coupling-lever, a tripping-leveroperatingto trip the coupling-lever, and through the latter uncouple the rods R R, and a lever operating to carry one of said rods into position for coupling, for the purposes specified.
4. The combination, with the slide-valve rod provided with a toothed portion or rack, and the eccentric-rod coupled detachably to the valve-rod, of a coupling-lever, a trippinglever operating to trip the coupling-lever, a pinion arranged to mesh with the toothed portion of the valve-rod, and a lever for rotating said pinion, for the purposes specified.
In testimony whereof I atfix my signature in presence of two witnesses.
HERRMANN OELERT.
