Specification of Letters Patent.

Application filed March 7, 1914. Serial No. 823,142.

To all whom it may concern:

Be it known that we, FREDERICK J. HARRI- soN and WILLIAM J. KNOX, citizens of the United States, residing at Dubois, Pennsylvania, have invented a certain new and useful Improvement in Locomotive-Pilots, of which the following is a full, clear, and eXact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a front elevational View of a locomotive pilot of our improved construction, the same being applied to a bumper' beam. 'Fig. 2 is a plan view of the pilot ap plied to a bumper beam with a portion of the latter broken away. Fig. 3 is a side elevational view of the pilot. Fig. 4 is a vertical section taken on the line lf-4 of Fig. 1. Fig. 5 is an enlarged detail section taken on the line 5-5 of Fig. 1. Fig. 6 is a sectional View similar to Fig. 4 and showing a modified construction of the pilot. Fig..7 is a front elevational view of the upper portion of a modified form of the center section of the pilot. Fig. 8 is an enlarged detail section taken approximately on the line 8-8 of Fig. 7

Our invention relates to new and useful improvements in locomotive pilots of the general type shown in Patent No. 1,071,155, issued to us August 26, 1913, the principal objects of our present invention being to generally improve upon and simplify the constructions disclosed in the patent aforesaid; to construct a pilot, the main body portion of which consists of a skeleton frame preferably cast, and to combine therewith a separate center section preferably cast, and comprising a coupler pocket, a support for the coupler head, and the center slats for the pilot. Y

Further objects of our present invention are: to provide a pilot having slats which can be readily detached and replaced in case ofV breakage; to provide a couplerpocket having a readily detachable plate or bracket which performs the function of a coupler head seat or support; to form integral with the base of the pilot plates 4which perform the function of steps to enable trainmen to readily mount the pilot and bumper beam, and further to provide a pilot of compara tively simple construction, of great strength and rigidity, and which can be readily applied to or detached from the locomotive bumper beam.

With the above and other objects in view, our invention consists in certain novel features of construction and arrangement of parts, hereinafter more fully described and claimed.

As shown in the drawings our improved pilot is in the form of a skeleton frame preferably cast in a single piece and comprising a horizontally disposed triangular base l, a pair of end uprights or posts 2, and a horizontally disposed top rail 3. The end uprights or posts 2 project above the rail 3, and said upwardly projecting portions are fixed in any suitable manner, preferably by means of bolts 4, to the locomotive bumper beam 5. Formed integral with and projecting rearwardly from the upper portions of the posts 2 are brackets 6 which engage the underside of the bumper beam, and are fixed thereto in any suitable manner. Formed integral with the ends of the triangular base 1 and the lower ends of the posts 2 are horizontally disposed plates 7 which constitute steps to permit trainmen to readily mount the pilot and bumper beam.

rThe upper portion of the rail 3 is cut away at its center as designated by 8 in order to receive the upper portion of a separate center section of the pilot hereinafter described, and to compensate for thus cutting away said top rail, a horizontally disposed flange 9 is formed integral with the lower portion of the center of said rail, which Harige projects rearwardly and bears against the underside of the bumper beam 5. The'slats 10 of this form of pilot are preferably constructed of wood4 with their upper ends attached bv means of bolts or screws 11 to the rail 3. The lower ends of these slats are attached in any suitable manner to the base member 1, andby reason of the triangular form of said base member, all of the slats occupyy inclined positions. rlhe independent center section which includes the' coupler pocket, coupler support and center slats ofthe pilot is formed in a single piece, preferably by casting, and includes a vertically disposed plate 12 which is fixed inany suitable manner to the central portion .of the bumper'beam 5, and the lower portion of this plate occupies the cut awayportion. of the top rail 3. Formed integral with and Patented Apr. 13, 1915..

projecting forwardly from this pl'ateris` a housing comprising side walls 12a, top plate 13, and bottom plate 14, and the space withn in this housing is adapted to receive the shank of a coupler head. The plates 13 and 14: are perforated so as to receive the coupler head attaching pin. Formed integral with the plate 12 below the bottom plate 14 is a forwardly projecting plate 15 which forms a seat or support for the coupler head. Formed integral with the lower portion of the plate 12 is a depending plate 16 which is attached in any suitable manner, preferably by means of rivets, to the central portion of the member 3 below the openingv 8 therein. Formed integral with the plate 12 and housing therein is a downwardly and forwardly projecting skeleton member 17 which forms the center slats for the pilot, and the lower end of this member is attached by rivets or like fastening devices to the central portion of the base 1.

In Fig. 6 we have illustrated a pilot wherein the slats, instead of being constructed of wood, are formed of metal tubes 18, such as old flues, the same being cut into sections of proper length and having their ends ilattened and attached by means of rivets or like' fastening devices to the top rail 3 and basef1.

In Figs. 7 and 8 we have shown a coupler pocket provided with a detachable coupler support in the form of a. plate 19 which is adapted to normally rest upon a pair of lugs 20, which latter are formed integral with the upper portion of `the skeleton member 17. These lugs 2O are perforated and receive depending lugs 21 which are formed integral with'the plate 19.V Formed integral with the rear edge ofthe plate are upwardly projecting lugs 22 which,when the plate is properly positioned' on the member 17, engage behind a, portion of the front wall thereof. (See Figs. 7 and 8.) By virtue of the construction just described, the coupler head supporting plate can be readily replaced in case of breakage. A pilot of our improved construction is comparatively simple, can be easily and cheaply manufactured, is very strong and rigid, and can be easily applied to a locomotive bumper beam.

It will be readilyunderstood that minor changes in the size, form and construction lof the various parts of Vour improved locomotive pilot may be made and substituted for those herein shown and described, without departing from the vspirit of our invention, the scope of which is set forth in the appended claims.
