One object of my invention is to make a locomotive pilot, preferably of shaped bars cut into lengths, assembled and welded to make a unitary structure.

A further object of the invention is to make the entire pilot of angle bars.

In the accompanying drawings:

Fig. l is a plan view of my improved pilot;

Fig. 2 is a front view Fig. 3 is a side view;

Fig. 4 is a sectional view on the line 44, Fig. 3;

Fig. 5 is a detached perspective view of the upper transverse member of the pilot to which the long angle bars are welded; and

Fig. 6 is a plan view of the central upper member to which the short bars are secured, the view showing the member before being bent into shape.

The views illustrate the pilot detached from a locomotive or other rolling stock and it consists of a base frame 1, comprising a transverse angle beam 2, which extends from one side of the pilot to the other and a front '25 member 3, which is made of an angle bar bent at the center 4 and welded to the transverse member 2 at each end. Extending from the center of the member 3 to the center of the member 2 is a tie member 5, made of '80 two angle members 5a welded at their outer ends to the member 3 and at their inner ends to the member 2. 66a are vertical members, made also of angle bars, which extend from the transverse member 2 of the base 85 frame to a point abovethe pilot proper, in

order to provide means by which the pilot can be secured to the bumper or front of the locomotive.

Extending from the angle member 6 to the angle member 6a at each side of the pilot is an angle bar abutment 7 It will be noticed on referring to Fig. 3 that the angle members 7 are arranged so that their edges 88 rest against the rear member of the an '41 gle members 66a, so as to provide an inclined surface 9, to which the beveled ends of the long bars 10 of the pilot are secured by welding. The lower ends of the bars 10 are cut at an angle and welded to the upper face of the angle bar 3 of the base frame 1.

In the present instance the bars 10 are made from angles and are arranged so that the corner edges project forwardly. The side members of the bars form an-inc-lined surface as clearly shown in thedrawings. The bars 11 are also preferably made of angles, and are located at the center of the pilot, and are shorter than the bars 10, and are beveled at their lower and upper ends so as to fit against the base member 3 of the base 1, and against the vertical portion of a frame 12, and they are welded both to the base and top of the member 3 and the front surface of the member 12. The frame 12 is made of an angle bar, one member of the bar being cut away at 13, 6 so that the bar can be bent at 14 to produce a member to which the upright bars 11 are secured, and the end por- -t-ions 15 of the frame 12 are welded to the uprights 6. This construction allows room a coupler. 16 are corner brackets which are secured to the rear of the'pilot structure andare arranged to be attached to the underside of the bumper. Each bracket 16 is made of pressed sheetmetal in the present instance and has a vertical flange 17 at the front, and a horizontal flange 18 at the top. The flange 17 of each corner bracket is welded to the vertical members 66a of the pilot, but in some instances the brackets may be secured to the pilot by bolts or rivets.

The members 66a are perforated for the bolts which secure the pilot to the bumper of the locomotive, and the upper flanges 18 of the corner brackets 16 are also perforated for securing bolts.

I preferably construct the pilot entirely of angle bars, as shown in the drawings. The

bars 10 and 11 may be made in other shapes such as channels, Ts, rectangular or round solid bars, or tubular bars, without departing from the essential features of the invention.

By the above description it will be seen that the pilot is made of bars or shapes either made by rolling or by pressingyand the bars may be made of any suitable material. The parts are welded together, to form a unitary structure.

I claim:

1. A pilot consisting of a base frame made of a, transverse angle bar extending from one side of the pilot to the other; a forward angle bar bent at the center and welded at its ends to the transverse member; a thrust member consisting of two angle bars extending from the rear member of the base frame to the forward member and welded thereto; vertical members at the rear of the pilot and formed of shaped bars; horizontal upper members at each side of the pilot; av

central upper horizontal member between the side members; and inclined members welded at their ends to the forward member of the base frame and to the upper members.

2. A pilot consisting of a base frame of angle bars; vertical members at the back of the pilot; two horizontal members, one at each side of the pilot; a central horizontal member bent to shape and welded to two of the vertical members at a point below the rim of the line of the horizontal members, to leave space for a coupler; and inclined members formed of angle bars and welded at their lower ends to the outer member of the base frameand at their upper ends to the horizontal members.

3LA pilot consisting of a base frame eX- tending fromone side of the pilot to the other; a forward angle bar bent at the center and welded at its ends to the transverse member; vertical members at the rear of the pilot; a horizontal upper member at each side of the pilot; a central horizontal member between the side members; and inclined members secured at their ends to the forward member of the base frame and to the upper members.

l. A pilot consisting of a base frame of angle bars; vertical members at the back of the pilot and secured to the base frame; two horizontal upper members, one at each side of the pilot, said members being secured to the vertical members; a central horizontal member secured to the vertical members; and inclined members formed of angle bars and welded at their lower ends to the outer portion of the base frame and at their upper ends to the horizontal member.

THEODORE J. HAMMER.
