UNITED STATES PATENT OFFICE.
JOHN HAHN, OF NE\V YORK, N. Y.
SWITCH OR SIGNAL SETTING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 423,554, dated March 18, 1890. Application filed July 23, 1889. Serial No. 818,406. (No model.)
To all whom it may concern:
Be it known that 1, JOHN HAHN, of New York city, New York, have invented an Improved Switch and Signal Setting Mechanism, of which the following is a specification.
This invention relates to an improved device to be applied to locomotives and other motors, and by means of which the engineer can directly set the switches, signals, and gates on approaching them. 7
The invention consists in the various features of improvement more fully pointed out in the claims. I
In the accompanying drawings, Figure 1 is a sectional side view of my improved mechanism, showing the pivoted bar or lever raised.
Fig. 2 is a top view of the mechanism; Fig.-
3, a sectional side view with the lever lowered; Fig. 4, an enlarged side view of a modification of the lever 5 Fig. 5, a sectional side view, and Fig. 6 a top view of the switch and signal operating mechanism engaged by the lever The letter a represents a locomotive or other motor, to which there is pivoted by pin 1) a lever, shoe, or bar 0, adapted to be turned on its pivot, so as to be raised or lowered at one end. WVhen the lever is raised, it clears the ground 5 but when it is lowered it engages the switch, signal, or gate setting device, as hereinafter described.
In order to operate the bar 0, I employ the following mechanism: d is a hand-lever c011- nected by rod c and arm f to a rock-shaft g. This rock-shaft is provided with staple h, passing through a perforated bar 1', having a tooth or notch 11'. The lower end of bar 11 is pivoted to the lever c. When the lever cl is thrown forward, it rocks shaft 9 and raises the staple, which in turn, through bar 1, raises lever c, Fig. 1; but when the lever cl is thrown backward the shaft g is rocked in the opposite direction and the staple is lowered to in turn lower lever 0 through bar 1', Fig. 3. When arrived in this position, a spring it draws bar '6 into an approXimately-upright position, so that its notch z" engages a block j, which looks lever c in its lowermost position and prevents it from rising automatically when it encounters pressure from the bottom. A second spring j causes a disengagement between notch t" and block j when the lever 61 is thrown forward.
which is set by the lever c.
The lever 0 should be provided with a corrugated lower surface to engage a gearing on the switch-setting device and revolve the same; but when the mechanism is to operate upon a smooth surface a rack c is applied to the lever, which engages its teeth and has a smooth lower surface.
In Fig. 4 I have shown a leaf-spring attached to the upper surface of the lever c by a pair of screws 70*, so that a free space is left between spring and lever. This spring extends only over the forward half of the lever, and it receives the pivot 19, by which the lever is connected to the locomotive. It will be seen that as the lever is oscillated in manner described the slight play between lever and spring will reduce the shock when the lever engages the switch-settingdevice.
In Figs. 5 and 6 the mechanism is shown This lever passes over a pair of spring-levers m, and when lowered, as described, depresses them. The levers on, being depressed, move rack m down? ward to turn cog-wheel m This cog-wheel by its shaft m revolves cog ant-meshing into cog m which turns pulley m. This pulley winds the cable of, which operates the switches, gates, or signals.
What I claim is-- 1. The combination of hand-lever d, with a rock-shaft connected thereto, a staple, a perforated bar, and with a pivoted lever 0 connected to said bar, substantially as specified.
2. The combination of a pivoted lever c with a notched bar 2', operated by a handlever, and with a stop j, for engaging the notched bar, substantially as specified.
3. The combination of the following elemen ts: a hand-lever, a rock-shaft connected thereto, a staple and notched bar 1', operated by the rock-shaft, a pivoted lever 0, connected to bar 2', and a stop for engaging said notched bar, substantially as specified.
4. A lever c, pivoted to a motor, with spring is, attached to the lever, in combination with mechanism for raising and lowering said lever, substantially as specified.
