Specification of Letters Patent. Application filed December 30, 1908. Serial No. 470,094.

To all whom it may-concern: l

Be'it known'that 1,.TILLIAM PHILIP SMITH, a citizen of the United States, and a resident of El'Paso, in the county of El Paso and State of Texas, have invented a new and Improved Signaling Device, of which the following .is a full, clear, and exact description. t

This invention relates tosignaling devices for use on engines, railroad or trolley cars. The object of the invention is to provide an improved device which may be operated from the cab of an engineer by the operator of a car.

In its present'embodiment, itcomprises a plurality 'of levers rranged to display signals or be housed wi hina, asing, and mechanism whereby the levers ay be locked in either position,- and also means for locking the operating mechanism, Said loekin or other locality occupied by the operator;

The invention consists in the construction and'co'mbination of parts, t9 be more fully described hereinafter and particularly set forth in theclaims.

Reference is to be had to the accompanying drawings, forming a part of this spec'ifi cation, in which similar characters of reference indicate corresponding parts in all the views, and in which,

Fi re 1 is a perspective view, showing the evice applied to a locomotive boiler;

' Fig. 2is a front elevation, dpartly insection,

showing the device applie to aboiler, and

. having additional signals displayed; Fig. 3

is a horizontal section, taken on the line 3-3 in Fig. 2; Fig. 4 is an enlarged detail view, in sectlon, of the mechanism for lock-y P g ing t e levers agalnst movement; and Fig. 5 is a detail view, on an enlarged scale, showing the means for locking the operating mechanism.

'As at present shown, the mechanlsm 1S arranged to display four green signals, 1,2, 5

and 6, and two white signals, 3 and 4. It is to be understood that the number and colors of the signals may be varied to suit various requirements.

Although the mechanism is shown mount-= ed upon the front endof a locomotive boiler,

it will be understood'that said mechanism may be mounted upon'a car orin any other the spirit of the invention. Y

The signal may comprise a disk mounted suitable locality, without departing from Y I larto the rodlO.

upon one end of a lever 8. Said lever is pivoted about a rod 10 mounted in a bracket 12 which is secured to the outside of the boiler 14 of the engine. The lower end 15 of the lever 8 is pivotally connected-to one end of a link 16. The other end of the link 16 is pivotally connected to the upper end 17 of a lever 18. Said lever is pivoted about a rod 19, which may be supported at its ends in a casing or housing 20.- The lower end of the lever 18 is pivotally connected to one end of a link 22. The other end of the link 22 is pivotally connected to one arm 24 of a bell-crank lever 25. Said bell-crank lever is pivoted about a vertical stud 26 mounted in lugs 27 extending laterally from a bracket 28, which is bolted to the outside of theboiler 14.' The arm 30 of the bellcrank lever 25 is connected to a rod or other operating instrumentality 31, which extends to the cab of the engine.

The signal 3 comprises a on one end of a lever 34, also pivoted about the rod 10. The other end of the lever 34 is pivotally connected. to one end of a link 35, the other end of which is pivotally connected to the'upper end 36 of a lever 37 which is also pivoted about the rod 19; The lower end of the lever 37 is pivotally connected to one end of a link 38, the other end of which is pivotally connected to one arm 39 of a bell-crank 40, which is also pivoted about the stud 26. The arm 42 of the bellcrank lever 40 is connected to a rod or other instrumentality 44 also extending to the cab of the engine.

The signal 5 comprises a disk secured to one end'of a lever 45 pivoted about the rod 10. Said signal 5 and also the signal 6 are markers, which are used when the engine is to be backed up. As these signals are seldom displayed as compared with the signals intended to be operated by the engineer, they may be operated by hand from the front of the eng1ne.. 1

The signal 2 comprises a disk mounted upon one end of a lever 48, pivoted about a 'rod49's'uitablysugported in a manner simihe lower end of the lever 48 i's pivotally connected to one end "of 'a link 50,-:which has its other end pivoted to the 1ever 18..; p

r The signal 4 comprises a disk mounted on one end of a'lever 52, which is also pivoted disk mountecb aboutthe rod 49. 1 The other end of the lever 50is pivotally connected to oneend of a link 54, having its other end pivotally connected to the lever 37.

In order to support-the signal levers when displaying the signals, a series of yokes 58, 59 and 60 are secured together and mounted 'upon an upwardly-projecting arm 61 of thebracket 12. A locking bolt 64 is slidably mounted in the arms. 61 and 65 of .the bracket 12 and extends through the yokes 58, 59 and 60 above the point where the levers are fulcrumed about the rod 10. Said bolt 64 is provided with a collar 66 and a coiled spring 67 surrounding said bolt and I extending between the collar 66 and the arm 65 on the bracket 12 A similar set of yokes '70, 71 and 72 are secured together and mounted upon one arm 73 of a bracket 74 fastened upon the boiler 14. A locking bolt 75 is mounted to slide in the bracket 74, and

extends through the yokes above the rod 49 in a manner similar to that of the locking bolt 64.

The casin or housing 20 is provided with bolts 78 and 80, which extend through the same and connect both sides thereof, to formsupports for the levers of the signals which are obscured from view. Said casing may also be utilized to display the number plate of the engine. Said casing also protects the signals from the heat of the boiler and from rain and dirt. Said casing is suitably supported from the front of the boiler by ro s 81 and 82.

A rod 85 is journaled in bearings 86 and 87 formed upon brackets 88 and 89 respectively, which are bolted to the upper side of the boiler 14. Sleeves 90 are secured to the rod 85 and provided with cars 91, to which the upper ends of springs 92 may be fastened. The lowerends of said springs are secured to the boiler. An arm 94 is secured to one end of the shaft 85 and spans the looking bolt 75 at its lower end. Said arm 94 is arranged to engage a collar on the-locking bolt 75 similar to the collar 66 on the locking V bolt 64. An arm 96 is secured to the other end of the shaft 85, and has its lower end spanning the locking bolt 64 and engaging the collar 66. Asleev e 98 is secured to the arm 96. A link 99 is pivotally connected at one end to the sleeve 98 and at its other end to the upper end 100 of a lever 101, fulcrumed about apin 102 mounted upon "the of the bell-crank lever 25.

on a bracket end with a depending projection 114, which is adapted to lie in the path of the arm 24 The free end of the spring-arm 109 is provided with an upwardly-extending projection 115, which is adapted to lie in the path of the arm 39 of the bell-crank lever 40. When the cam 106 is turned so that the spring- arms 108 and 109 assume the dotted-line position shown in Fig. 5, the hell-crank levers 25 and 40 are 3 free to be moved -by theiroperating connections 31 and 44. Until these spring-arms are thus moved, said bell-cranks cannot be moved to operate the signals. The junction of the lower end of the lever 101 with the link 105 is connected to a yoke 120,'which is also connected to a rod 121 extending to the cab of the engine. i

The operation of the device is as follows: In order to operate the signals, the rod 121 is pushed forward, so that the joint between the lever 101 and the link 105 may assume the dotted-line osition shown in Simultaneously t erewith the upper on of said lever 101 is moved toward the left, as vinwed in Fig. 1, thereby drawing the arms 94 and 96 in the same direction, which act u on the collars which are mounted upon the ocking bolts 75 and 64 respectively. This frees any signals which may be supported in the yokes 58, 59, and 71, but if the signals are all housed within the casing, it prepares the yokes to receive the signs. 5. At the same time the cam 106 forces the spring arms 108 and 109 apart, so that their projections 114 and 115 are moved out of the paths of the bell-crank levers 25 and 40. Thereupon the rods or connections 31 and 44 may be operated from the cab in order to. move the signals as desired. when the signals have been moved, the rod 121 is drawn toward the left, as viewed in F' 1, thereby movin 105 into the fa l-line position shown in Fig. 5. Under the action of the springs 92 and the springs 67and 74, the mechanism for moving the locking bolts and 64 is :(per ated. These springs may be so design as to automatically restore the locking mechanism as soon as the rod 121 is-released from the hands of the operator after the signals have been 0 erated.
