ADJUSTABLE Locolvlo'rlvE-PILOT AND DRAW-ena.v

, SPECIFICATION forming part of Letters Patent No. 743,864, dated November 10, 1903.

Application filed April 20, 1903.

To a/ZZ whom, L'U' ntcty concern:

Beit known that I, EDWIN R. HALEsWon'rH, a citizen of the United States, residing at San Bernardino, in thecounty of San Bernardino and State of California, have invented a new and useful Adjustable Locomotive-Pilot and Draw-Bar, of which the following is a specification.

My invention relates to improvements in the means for supporting locomotivelplots and in improved construction of the draw-bar and its connection with the pilot and in details of construction of parts of the draw-bar and pilot, which will be fully described here-v inafter.

The objects of my invention are to provide new and improved means for adjustably attachin g the pilot to the pilot-beam and to provide new and improved construction of parts of the pilot and draw-bar.

The accompanying drawings illustrate the invention, and referring to the same, Figure I is a vertical sectional view taken longitudinally through the pilot. Fig. II is a side elevation of the pilot. Fig. III is a plan view of the pilot. Fig. IV is a sectional detail taken vertically through the pilot-beam and shows a portion of one of the pilot-standards. Fig. V is a front elevation 'of the Vsanne with the nut removed and the attaching-bolt shown in section. FigVI is a detail of the improved turnbnckle. Fig. VII is a front elevation of the draw-bar casting attached to a portion of the pilot-beam with the pilot-supporting straps attached thereto. Fig.v VIII is a plan view of my improved turnbuckle.

1 designatesthe usual pilot-beam, to which is attached the'draw-bar casting 2,' the latter being formed with a base 3, which abuts against the front face of the pilot-beam 1 and from which forwardly project a pair of wings 4, which are united at the bottom by a Wall 5. Projecting rearwardly from the upper edge fromrlthebaserS is a, bracket 7, which lies upon the top face Vof the pilot-beam l1, the

drawbar casting Zbeing fastened to the pi-v lot-.beam by means of bolts S, which pass through the bracket 7.

9 designates the draw-bar, which on the lower side of its rear end is provided with a lug 10. The lug 10 is rounded except for its forward face, which is flat.

the pilot-beam V1. 'standards 16 and secure the proper positionsentira resale. on man.)

opening formed by cutting away the wall 5 nea-r the base 3. In order to form a bearing against which the shoe 1l may draw, I provide another shoe l2, which is bolted, preferably, to the under side of the wall 5 and has4 a concave rear face against which the convex face of the lug 11 bears when the drawvbar 9 receives the tensile strain.

The draw-bar 9 is pivotally attached to the wings et by means of a bolt 13, which passes through the wings 4 and through an elongated slot ljlin theLdraw-bar 9. Interposed betwebieach wing 4 and the draw-bar 9 are coil compression-springs l5, the width of the draw-bar being somewhat less than the space between the wings 4. The length of the slot 14 is enough to allow for sufficient play of the draw-bar, and it will be observed that the draft does not come upon the bolt 13, but is taken up by the shoes .12 and 1l. The rear end of the draw-bar lies very close to the base 3, and the object in forming the lug 10 undercut at its rear portion is to allow the drawbar to vbe tilted. By making the shoes 11 and 12 removable they may be replaced by new shoes when they become so worn as to unfit them for use.

The pilot may be partially carried by standards 16, whichl may extend downwardly from In order to adjust the ing of the pilot, I provide the upper end of each standard 16 with an elongated slot 17. In the slots 17 are inserted plugs 18, which lie above and below the bolts 19, which se- Ecure the standards 16 to the pilot-beam 1.

When the pilot sags and 4it is wished tn raise or lower the same, one or the other of the plugs 18 in each slot may readily be removed and the standards 16 slipped up or down', as the case may be, after which new plugs may be readily inserted to lill the gaps between the bolts 19 and the remaining plugs, after IOO which the nut may be screwed down. tofore in adjusting the pilot-frame it has been necessary to remove the standards 16, plug the old holes, and bore new holes, and this required the use of tools and occasioned considerable inconvenience. It will readily be seen that with the present construction the .adjusting of the pilot is accomplished quickly bar casting with a base 3, having elongated slots 20, through which bolts 2l pass. By loosening the bolts 2l and S the draw-bar casting may be raised and a shim placed under the bracket 7. The slots 20 allow for the raising of the draw-bar, after which the bolts 2l and S may be tightened. In order to further support the bottom frame of the pilot, I provide a pair ot' straps 22, which may be held in place by the bolts 2l and which may extend down and be attached to uprights 23 of the pilot-frame by means of bolts 24, which may pass through elongated slots 25 in the straps 22. The slotted ends of the straps 22 allow of an adjustment of the rear end ofthe pilot-frame relatively to the straps 22. The straps 22 also provide a solid full face, against which the nuts of the bolts 21 take, the straps 22 covering the slots 20.

In order to support the nose of the pilot, I provide a nose-brace 26, the lower front end of which may be hooked to an eyebolt 6. The upper rear end of the nose-brace will be connected by a hooked rod 27 with one of the bolts 2l. In order to adj ust the length of the nose-brace 26, I provide a novel turnbuckle. One end of the nose brace rod 26 passes loosely through a yoke-frame 29 and is provided with threads which engage a nut 30,.

which is held loosely in the yoke-frame 29. The other end of the frame is drilled and receives loosely the threaded end of the rod 27. 3l is a nut inside of the yokeframe and mounted on the threaded end of the rod 27. 32 is a set-nut on the rod 27. It will be seen that the threads are not formed in the frame 29, as is usual in the ordinary turnbuckles, but that the rods pass loosely therethrough. Therefore by loosening the nuts 3l and 32 it is possible to quickly shift the frame 29 along the rods. The set-nuts may be run back from the frame 29, and as the sides of the yoke-frame 29 lie over the faces of the nuts 30 and 3l they act as a wrench to turn the nuts, so that the nose-brace is tightened by merely turning the yoke-frame 29. The nuts 30 and 3l have right and left threads.

In order to hold the draw-bar in a horizontal position, I provide a pin 33, which passes Herethrough the wings 4 and lies over the top of the draw-bar.

IVhen the draw-bar is not being used, the pin 33 may be withdrawn and the draw-bar may be dropped into the position shown in Fig. II, so that it rests between the mid-ribs of the pilot.

In order to cover the space between the mid-ribs of the pilot, I provide gates 34, each of which consists of a pair of slats carried by rods 35, the slats being spaced apart by wooden washers 36.

37 designates hinges, which carry the gates and are mounted on the mid-ribs.

rlhe gates may be swung back to allow the draw-bar to be dropped .into place, after which they may be closed-over the space and cover the draw-bar.
