SPECIFIGATION forming part of Letters Patent 1\`.|'o. 519,009,l dated May 1, 1894.

Application tiled January 18, 1894:. v Serial No. 497,325. (No model.) v

To @ZZ whom it may concern:

13e it known that L-WILBUR P. SQUIER, a citizen of the United States, residing at Blair, 1n the county of Washington and State of Nebraska, have invented a new and useful Train-Order Signal, of which the following is a specification.

My invention relates to improvements in railway train order signals in which a light with different 'colored glass is used'for night signals and a colored signal board for day work; and the objects of my improvement are, irst,-to provide such 'an apparatus in which all the signalingfparts, shall both individually, and collectively, have anormal tendency to give the stopping or danger sign; second,-toprovideasignaluniversallyadaptable to differently located depots or signal stations; third,-to avoid the disastrous effects of tempestuous, freezing or windy weather; and, fourth,-to provide an easily manipulated, simple, strong, durable, and positive acting signal, together with other important features more fully hereinafter set forth. I attain these objects with others of minor importancethrough the medium of mechanism illustrated in the accompanying drawings, in which- U Figure 1, is a side elevation, partly in section portions being cut away to show the assembly of the several parts, of the whole machine set up for use.y Fig. 2, is a vertical cross section on the broken line X, Z, in Fig.'1, looking toward the signal board 3.- Fig. 3, 1s a top View of the rock-shaft 9 having the arms 33 and 33 carrying the colored lenses 4and 4'; and Fig. 4, is an elevation ,of the operating wheel 16.

Similar numerals refer to similar parts throughout the several views. The horizontal tube 1, has one end seated against thewall 22, a post or other like perpendicular support, the opposite ends snugly inserted in the thimbles 13 and 13 projecting centrally from opposite sidesand near the top of the lamp or lantern-case 28; an open clamping ring 14-having the tightening bolt 14 is placed on the thimble 13 to secure it rigidly to the tube 1` andprevent turning or slipping; the top of the vring has an eye by which to attach guy rods 15, to prevent lateral and vertical motion of the extended end of the tube. The rock-shaft 2 is journaled centrally through the tube, preferably in hardwood bearings 12, 12,'and 12, the outer projecting end has the signal-board 3, rigidly attached by U shaped clamping bolts 27 and 27',

. the inner end .passes loosely through an aperture in the wall 22, and is provided with the operating wheel 16 rigidly attached thereto. Within the lantern case 28, the opening 6 is cut in the tube 1,-shown in cross-section in Fig. 2,-and the rock-shaft has the stud or arm 5 so set as to oscillate in said opening, and limit the rocking of the shaft to a onefourth revolution,the signal board 3 being so adjusted on the shaft as Y to stop either in a horizontal plane as in Fig. 2, or a vertical plane as shown in Fig. 1; the operating wheel 16 has on its side adjacent to the wall-22, the projections 23 and 23 and between these on thewall is set the stop .blockl 24 to limit the motionof the wheely to a one-fourth revolution agreeing with the motion ofthe shaft 2, the object of which is to reinforce the stud 5 and prevent injury by the application of unnecessary force on the wheel, and make apositive stop, and as an alternative in case the stud 5 is broken or desired to be omitted. The rock-shaft 9, has its ends 9 and 9" pivoted in the bars 10 and 10', and spans the case 28 at one side and at right angles to the shaft 2; near its ends the arms 33 and 33 project 'at right angles, and at the ends of the arms are the colored glass disks or lenses, set to normally rest on the buffers 2l and 21 one at each side of the lamp 11 between it and the sight openings or lenses of clear glass 17 and 17v in the case 28, or to swing up to the posi` Vtion indicated by the broken line in Fig. 1.

A bifurcated arm projects from the rock-shaft 9, forming theslot 29, between and parallel with the arms and directly beneath the opening 6 in the tube `1; the eye-boltS is seated in this slot and adapted to'slide therein and `be fastened at any point; the chain 7 has one end attached in the eye of the eye-bolt, the other end passed up through the opening 6 into the tube, over the shaft 2 to which it is attached by the pin 30; by changing 'the position of the eye-bolt iii-the slot, therange of action of the colored disks 4 and 4v isvaried and adjusted as desired. The wheel 16 is grooved on its periphery to receive the cord IOC 25, which is thereto attached; and a cleat 2G is attached to the wall on which to fasten the free end of the cord, when the signal board is horizontal and colored disks raised.

To avoidthe turning of the signal board by the wind or storms it is constructed with its axis of revolution corresponding, or nearly so, with its axis of symmetry. But, to insure 1t takingits position in a perpendicular plane when released by the operator or by accident to or failure of other parts of the apparatus, its center of gravity is xed at one side or away from said axes. This is done in the construction shown, by the additional reinforcing bar 2O attached at one edge. The same result maybe reached by a board made of a single integral piece thickened at one edge. The projected end of the thimble 13 is made conical, the shaft 2 passing loosely through an aperture at the apex, and this forming the chamber 18, around the shaft between the apex and the adjacent hardwood bearing 12. At the base of the cone, on the under side the opening 19 is made, communicating with the chamber, to drain out any water that might be driven in around the shaft during storms.

The lantern or lamp 11,has a circularbase and is retained by lugs 31 and 31 that pass through notches in the bottom of the case; further the lamp is intended to be supplied with a globe and bail so that it may be removed, cleaned, lighted and carried, being independent of the other parts.

The tube 1 servesa double purpose of housing the rock-shaft 2 between the operating wheel and lantern case, and with the collar 32 and suitable guys, is a horizontal support for the whole apparatus projecting at right angles to the road.

Inm operation when the cord 25 is released all the parts normally assume the positions shown in Fig. 1, showing the broad surface of the signal-board, and the colored glass disks, giving the danger or stop sign; the weight ot' the arms and disks, with the eccentrically placed Weight of the signal-board being sufficient to overcome all frictional resistance; draft on the cord, turns the shaft 2 a onefourth revolution, bringing the signal board to a horizontal plane, the chain '7 winds up on the shaft and raises the colored disks showing a white light and indicating a clear track and no stop; the cord 'is then fastened tothe cleat and retains the signals in this position.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A signal-board having ahorizontal axis of revolution corresponding with its axis of symmetry, and parallel with its plane and its center of gravity eccentric to Vsaid axes, to normally sustain the board in a vertical plane substantially as described.

6. In a signaling apparatus, a lantern case having a revoluble shaft projecting therefrom in combination with a cone shaped projection on the case to form a chamberaround the shaft, the cone having an opening at its apex to loosely receive the shaft, and an outer opening at its base communicating with the chamber, substantially as described.
