Specification of Letters Patent.

Patented July 16, 1907.

Application tiled November 21, 1906. Serial No. 344,395.

To all whom it may concern:

Be it known that I, BENJAMIN Tomi/En HAMILTON, a citizen of the United States, and a resident ol' Fort Smith, in the county of Sebastian, and State ol' Arkansas, have invented a new and Improved Locomotive-Pilot, of which the following is a hill, clear, and exact description.

This invention relates to pilots designed to be used on locomotives, and particularly on those engines used for both switching and road service.

Switching engines are provided on their forward ends with a draw beam having a coupling attached thereto adapted to be connected with a car in [ront of the engine, and such engines are generally used without a pilot or with a stub pilot so as not to interfere with coupling the engine to a car on its forward end. .Where no pilot is used the engine is not suitable for road service, for the reason that live stock when struckby the engine going at a high rate of speed are liable to be thrown under the train thereby often causing serious accident. When, moreover, a stub pilot is used the draw beam projects so far beyond the face ol' the pilot that the live stock when struck frequently become lodged under the draw beam and fall oft' the pilot on to the track, frequently derailing the engine.

My invention has for its object, therefore, to provide a pilot adapted to be used on an engine designed for either switching or road service. Such objects I accomplish by the means illustrated in the accompanying drawings, in which drawings like characters of reference indicate like parts throughout the views, and in which Figure 1 is a vertical section of a pilot embodying my invention, taken on the line 1-1 of Fig. 3; Fig. 2 is a similar View oi the pilot shown in Fig. 1 with the parts differently arranged; Fig. 3 is a horizontal section taken on the line 3-3 of Fig. 1; and Fig. 4 is a detail taken on the line 4 4 of Fig. 3. c

As illustrated in the drawings, my invention comprises a pilot having a main and an auxiliary section. The main section comprises diagonally arranged side bars l having slats 2 of ordinary construction secured thereto at their lower ends, and at their upper ends connected in any suitable manner with a pilot beam 3 attached to the`forward end of. the engine. The rear ends of the side beams 1 are connected together by means of a transverse beam 4 having parallel longitudinal braces 5 connected therewith, and with the forward ends of the beams 1. The rear beam 4 is secured to vertical beams or hangers G attached at their upper ends to the pilot beam. A transverse plate or beam 7 is secured to the forward ends of the main section, adapted to support an auxiliary section composed of side bars 8 having slats 9 connected therewith at their lower ends, the upper ends of said slats being connected with side bars 10. The slats 9 are shorter in length than the slats 2 of the mainframe, and terminate below the plane ol' the lower surl'acc ol' a draft beam 1l secured to the pilot beam 3, so as to enable the auxiliary section ol' the pilot to be l'oldcd into the main section below said draw beam, as shown in Fig. 2.

The side beams 8 ol' the auxiliary section are provided with parallel extensions 8, and the upper side beams 10 ol' the auxiliary sections are also provided with parallel extensions, which have a sliding engagement with upper stationary guide bars 12 extending longitudinally of the pilot. The lower extensions S" ofthe auxiliary frame have a similar sliding engagement with longitudinal guide bars 13. The auxiliary central section of the pilot is movable longitudinally of the main [rame of the pilot by means of crank arms 14 mounted upon a shaft 15 which is journaled in boxes 1G secured to the hangers 6, as shown in Fig. 1. The shaft l5 is provided with hand wheels 17 and the cranks 14 are pivotnlly connected by means ol' pivot pins 141L with links 1S which are pivoted at their forward ends to brackets 19 secured to the upper' and lower portions of the auxiliary frame.

A locking device is mounted upon brackets 20, secured to the auxiliary frame, and consists of beams 21 mounted upon pivot pins 21XL and provided on their ends with links 22 having hooked ends 22ll adapted to loop the upper and lower edges oll the guide bars 12 and 13 and engage sockets 12 and 13 formed in said bars respectively. The looped ends of the links 22 are held in engagement on the guide bars 10 and 13 by means ol' the links 18 which bear against pins 21" attached to the beams 2l, thereby preventing the beams 2l from tilting on their pivots and holding the links on said guide bars, when the auxiliary section of the pilot is projected, as shown in Fig. 1. When, however, said auxiliary section is folded into the main section, as shown in Fig. 2, the links 22 are released from engagement with theI guide bars 12 and 13 by means of springs 23, which are securedto the brackets 20 and bear at their ends 23L against said beams, so as to release the links from engagement with the guide bars 12 and 13 and permit the auxiliary frame to be drawn into the main frame, as illustrated in Fig. 2.

The shaft 15, provided with the lower hand wheels 17, may be connected with a vertical shaft 24 by meatns of a bevel gear 25 secured to said shaft, and a similar gear wheel 26 secured to the shaft 15, and the vertical shaft 24 may be connected by means ol similar bevel gears with a shaft 27 journaled in bearing boxes 28 supported upon the pilot beam 3 and provided with hand wheels 29 so as to enable the auxiliary section to be operated by either the upper hand wheels 29 or lower hand wheels 17 located on both sides of the pilot.

When the device is in use for road service, the auxiliary frame is extended on the main frame, as shown in Figs. 1 and 3. When in such position the auxiliary frame is held against a backward movement by means of the links 18 and cranks 14. The auxiliary frame is further locked in position by means of the links 22 connected with the pivoted beams 21 and the guide bars 12 and 13.

When the engine is to be used for switching, the auX- iliary section may be folded into the main section by rotating either the hand wheels 29 or the wheels 17, thereby raising and drawing backward the cranks 14 and links 18, and also the auxiliary frame of the pilot, as shown in Fig. 2. As the cranks 14 and link 18 are raised and drawn backward, said links are released from the pins 21b of the pivot beams 21, thereby allowing the springs 23 to release the ends or' the links 22 from engagement with the guide bars, as shown in Fig. 2.

In the construction herein shown and described, I have embodied my invention in its preferred form. I do not desire to be limited to this construction, however, as other means having similar capabilities may be used without departing from the spirit of my invention, and in some instances I prefer to dispense with the tubular section shown herein, and substitute therefor other devices having similar capabilities, consisting of wooden or iron slats Working in keepers oi' any suitable construction.

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

l. The combination of a draw beam, yand a pilot having a stationary main frame and a-n auxiliary frame adapted to be folded into the main section below said draw beam.

2. The combination with a draw beam, of a pilot having a main frame provided with slats extending upward to the plane of said draw beam, and an auxiliary section adapted to be folded into the main frame and provided with slats stopped below said draw beam.

The combination with a draw beam, of a pilot having oppositely disposed stationary sections provided with slats extending to the height of said draw beam, and an intermediate auxiliary frame adapted to slide between said stationary sections and provided with slats stopped short of said draw beam.

4. A locomotive pilot comprising horizontally inclined side sections, and a central section adapted to be folded between or projected beyond said side sections.

A locomotive pilot comprising horizontally inclined side sections connected together at their forward ends by means of a transverse bar, and an auxiliary section provided with vertically inclined slats adapted to be retracted between or projected beyond said sections.

G. A locomotive pilot comprising horizontally inclined stationary side sections, and a central auxiliary section mounted to slide between the side sections or be projected therefrom, and means for locking said auxiliary frame in its projected position.

7. A locomotive pilot comprising horizontally inclined side sections provided with longitudinal guide bars, and an auxiliary section provided with slides adapted to engage said guide bars and enable the auxiliary frame to be projected beyond or retracted between said side sections.

S. A locomotive pilot comprising stationary side sections horizontally inclined and provided with vertically inclined slats, an auxiliary section provided with vertically inclined slats adapted to be projected beyond or retracted between said side sections, a rotatable shaft, and links connected with said shaft and said auxiliary section.
