J. H. MILLER. RAILROAD LAMP ELEVATOR.
No. 586,314. Patented July 13,1897.
UNITED STATES PATENT OFFICE.
JOHN H. MILLER, OF XVEILERSVILLE, OHIO.
RAILROAD-LAM P ELEVATOR.
SPECIFICATION forming part of Letters Patent No. 586,314, dated July 13, 1897.
Application filed October 30, 1896.
To all whom, it 7mm concern.-
Be it known that I, JOHN H. MILLER, a citizen of the United States, residing at lVeilersville, in the county of \Vayne and State of Ohio, have invented a new and useful Railroad-Lamp Elevator, of which the following is a specification.
The annexed drawings and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting but one of various mechanical forms in which the principle of the invention may be used.
In the said annexed drawings, Figure 1 represents a side elevation of my improved elevator, illustrating the position of the apparatus during the act of hoisting the lamp up to its seat. Fig. 2 represents a perspective view of the apparatus during the act of seating the lamp upon its seat, and Fig. 3 represents a similar View illustrating the position of the apparatus when the lamp is seated.
The semaphore-pole P, the top of which is adapted to form a seat for the signal-lamp, has pivoted, by means of pivots g, near the said top the arms to, having a rearwardly-projecting portion a, to which is attached a spring s,which, in conjunction with the stops a, cause the arms to project substantially horizontally from the pole.
The ends of the outwardly-projecting portions of the arms a are each provided with a pulley p, suitably mounted thereon, and with a downwardly-projecting curved lug j. A standard 0, provided with bifurcations c, is suitably fastened upon the pole and is provided at the top with two pulleys p, each so disposed as to be substantially directly behind one of the pulleys p. A dog or catch 6, formed with the downwardly-projecting arm 6, is suitably pivoted near the ends of the bifurcations c and is provided with suitable stops, which prevent it from dropping below a substantially horizontal position, and projects over the middle of the lamp-seat. A cross-bar m connects transversely the two arms a.
Suitable cords 4' pass over the pulleys p and the opposite pulleys p, the ends depending from the ends of arms a, to which ends is attached the signal-lamp by means of the suspenders 'i and the spreader-barfiwhich form a part of the lamp. Pins 1" are placed transverselyone in each of the cords and at equal distances from the spreader-bar f. The suspenders are of such a length that the lamp when suspended is in a position in which a line drawn through the center of its lenses is horizontal. The spreader-bar is made of sufficient length so that it will engage, when drawn up, the two arms a.
In operating the device the lamp is attached to the cords and drawn up to the top of the pole, where the pins r engage the ends of the arms a, which, on further drawing of the cords, rotate upon their pivots, carrying with them the lamp, until the lamp is directly over the seat, in which position the catch 6 catches the cross-bar m, and thereby locks the arms, whereupon the cords are released and the spreader-bar drops upon the curved arm e, slides off and into the lugs j, and the lamp is thus placed upon its seat. The parts are so adjusted that the spreader-bar and the lamp reach their respective seats simultaneously.
To unseat and lower the lamp, the cords are pulled until the spreader-bar lifts the dog 6 by engaging the arm 6. The cross-bar and arms are thus released, and the sprin gs s throw the said arms forward and thereby carry the lamp outwardly from the pole, whence it may be lowered to the ground.
The arms a are formed with a curvature, so that when the lamp is seated they shall not cross the lenses.
By these means I obtain a simple and effectual lamp-elevating apparatus which en ables the light to be seen at all times during the operation of hoisting, seating, unseating, and lowering.
Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means covered by any one of the following claims be employed.
I therefore particularly point out and dis- 1 tinctly claim as my invention 1.
