This invention relates to improvements in rallroad spreaders and it consists of the matters hereinafter described and more pa-rticu larly pointed out in the appended claims.

The primary object of the invention is to improve the general arrangement of the parts of the spreader, wherein it will be more,

strong and rigid, more symmetrical in appearance, better balanced and more convenient for operation in its intended use.

A further object of the invention is to provide a spreader wherein the operation thereof may be controlled from a central station or cab so arranged as to provide an unobstructed My invention consists generally in a spreader of the form, arrangement, construction and coaction of the various parts whereby the above named ob ects together ,with

others as well as the many advantages therer of as will hereinafter appear are attainable and my invention will bemore readily understood by reference to the accompanying drawings which illustrate what I consider, at the present time, to be the preferred embodiment thereof.

In said drawings I Fig. 1 is a view in side elevation of a railroad spreader embodying therein the preferredform of my invention.

Fig. 2 is a top plan view'thereof with the cab illustrated in horizontal section, the plane of said section being indicated by the line I inder. the front plow as a whole may be Fig. 3 is a transverse vertical sectional view through the spreader on an enlarged scale, the planeof the section being indicated by the line 33.of Fig.1.

Referring now in detail. to that embodiment ofthe inventionillustrated in the acusual front and rear wheel trucks 2 and 3 respectively for rolling engagement on the rails 4 of arailroad track. Said car is similar to what is usually termed a fiat car but in this instance its deck 5 is more in the form of an arrow, with awide pointed front endor platform 6, a rectangular rear end or platform 7 and a narrower intermediate deck portion 8. The construction just de scribed thus presents cut in or recessed sides 9 forthe car between the front and rear platforms along the intermediate deck portion 8. In Figs. 1 and Qthe deck portion 8 is broken away or foreshortened as shown. The deck is supported on pairs of center and side sills 10 and 11 respectively, the former being I-beains andrthe latter being channels with their flanges directed inwardly as best shown in Fig. 3. y

12 indicates the front plow of the spreader which comprises plow members 1313 that are normally disposed at a right angle to each other and diverge rearwardly from a common axis l l at the nose of plow to conform to thepointed end of the front platform 6. Said plow members are of a height at their rear ends approximating the height of the platform but are higher than said deck atthe nose so that material being spread by said plow cannot pile on the front platform. The nose of the front plow is cut away between its top and bottom ends as indicated at 15 in Fig. 1 to accommodatethe draw bar 16 when the spreader is in transport and this cut away portion is elongated vertically to permit a limited amount ofvertical adjusting movement of the front plow; Such vertical movement of the front plow is provided by an upright power cylinder 17 mounted on a pedestal18, at the nose endof the front platform 6. By means of said cylraised and lowered within certain limits and it is held in its raised position for purpose of transport by a locking pin 19 disposed in the. pedestal 18, said pin being actuated by a smaller and horizontally disposed cylinder 20 at therear of said pedestal. Eitherfront plow member 13 may be swung about the axis 14 into a position parallel with the other member when it is desired to move the material to be spread from one side of the track to the other, as is Well known in spreaders of this kind. Said plow members are normally locked in the full line position shown in Figs. 1 and 2 by means of a lug and wedge pin 21, thewedge being removed when it is desired to bring one member into line with the other.

At each side of the front platformfi is'an apron or auxiliary wing 22 which normally extends parallel with the sides of the front platform throughout their length. Said aprons are hinged at their front ends to the car, each by a vertical axis pin 23, positioned at the rear end of the associated front plow member 13 and prevent the material engaged and moved by the front plow from flowing under the car as it leaves the rear ends of the plow members. Normally such aprons parallel the platform but for light spreading in connection with the front plow they, may be swung about their axis pins 23 into the desired angular position and held therein in any suitable manner. To the rear end of each apron is fixed an extension 24 in the form of a flexible metallic plate which normally projects a suitable distance beyond the'rear of the front platform 6.

Arising from the intermediate'deck portion 8 and on each side thereof just to the rear of the front platform 6 is an upright wing post 25 in each of which a wing post carriage 26 is capable of a vertical guided movement. Such movement is imparted to the wing post carriages by means of upright fiuid pressure cylinders 26 positioned just within each associated wing post. Said posts each comprises a pair of longitudinally spaced front and rear angle bars 25 -25 so fixed to the side sills 11-11 that their bottom ends project below the same. The bottom ends of the pairs of angle bars on one side the car are connected to the like angle bars on the other'side of the car by a cross sill 27 while the top and bottom ends of the angle bars of each pair are connected together by U-shaped brackets 28. The top ends of each pair of angle bars forming a post are braced from the car body by oppositely and downwardly inclined braces 0r struts 2929.-

30-30 indicate the main spreader or side wings, one arranged'on each side of the car and normally positioned within the recesses 99. Each wing which is vertically edgewise disposed has a bottom edge cutter blade 30 and the inner bottom corners of each wing are cut away as at 30 so as to clear the ties of the railroad track when the wing is disposed at an angle to the car as when in its operative position. The inner end of each wing is embraced upon both sides by the front and rear walls of a hinge plate 31 and is hinged thereto for a swinging movement in a vertical plane by a horizontally disposed hinge pin 32. Said hinge plate has vertically spaced ears 31 positioned to engage similar ears 33 of a hinge block 33 rigidly secured to the bottom end of the carriage 26 slidable in an associated post 25. Through the engaged ears'of said hinge plate and hinge block there extends a vertically disposed hinge pin 35?. To the top end of each carriage 26 is fixed'a second hinge block 34 having laterally projecting spaced ears 34a which extend between top and bottom ears 36 of a second hinge plate 36, a vertically disposed pin 35, in line with the pin 33 before referred to, pivotally connecting the hinge block 34 and'hinge plate 36 together.

Each hinge plate 36 is pivoted by a horizontal pin 37 to the top or inner end of a wing lifting brace 38 the bottom end of which is pivoted by a pin 39 to brackets on the top edge ofan associated spreader wing 30 at a point substantially midway between its ends. Each wing lifting brace comprises inner and outer telescopic parts 3838", the inner part including a power cylinder 38 the piston rod 38 of which extends down through the telescopic part 38 to be fixed to the other telescopic part 38. When fluid under pressure is admitted to the bottom end of the cylinder, the wing is swung upwardly about its axis pin connection with its associated hinge plate into the desired angular position and is held therein in any suitable manner. hen air is permitted to escape from said cylinder the wing swings downwardly under its own weight.

As before'mentioned when either wing is in its normal inoperative position, it extends parallel with and alongside of the intermediate portion 8 of the car and is located wholly within the associated recess or cut in side of the car as best shown at the top of Fig. 2. However, when said wing is in its operative position it extends at quite an angle with reference to the car body as best shown at the bottom of Fig. 2. Swinging movement of each wing away from or toward the car body is imparted thereto by means operatively connected to vertically disposed cylinders 4040 one disposed on each side of the intermediate portion 8 of the car body at a point about midway between its ends. Each cylinder is suitably positioned adjacent an upright post 41, each of which comprises front and rear angle bars 41-4l", the front angle bar being the long- Ver. Each post 41 suitably supports a sheave shaft 43 journalled in laterally extending.

brackets 44 on each side of the car body portion 8. The said parts are so correlated that when fluid under pressure is admitted to one end or the other of one of said cylinders, the associated shaft 43 is rocked in one direct-ion or the other. To each shaft is operatively connected the inner ends of a plurality of folding braces 4545, the outer ends of which are suitably connected to the rear side of an associated side wing. Folding of said bars is permitted by a knuckle joint 46 in each bar. Thus when a shaft 43 is rocked in one direction, the associated wing 30 is caused to swing away from the car body into its angular operative position with respect to the car body by reason of the unfolding of the bars 4545 and when the said shaft is rocked in the other direction, said brace bars fold up and cause the wing to be swung into parallelism with the car body. hen the wing is in its operative angular position with respect to the body, its inner end is engaged or substantially engaged by the extension 24 of anassociated apron 23 so that the material operated upon cannot flow or be moved under the cutaway inner end portion 30 of the associated side wing to pile in a ridge along the rail.

47 indicates as a whole the operators control cab which is supported a suitable distance above the car body portion 8 between the wing posts 25 and cylinder posts 41. As shownhere in the posts on one side of the car body are connected together by longitudinally extending angle bars 48-48 the horizontal flanges of which face inwardly toward each other and the vertical flanges of which face upwardly, said angle bars assisting said posts in supporting the cab. Said cab has upright side walls 49 and upright front and rear walls 50 and 51, a roof 52, and a floor 47, the floor resting upon the horizontal flanges of the angle bars 48. In said side walls are windows 53 for light and air and said windows slide longitudinally on rails 49 so that they may be readily closed or opened to permit a clear vision fore and aft for the operator. In each front and rear end wall suitable doors 50"-51 are provided which are of the kind having panes therein for clear vision fore and aft. Suitable front and rear steps 5455 are also an'd plow members and other parts thereof on the respective sides of the car.

By arranging the cab in themanner described, there is nothing to obscure the full,

vision ofthe operator with reference to the workbeing carried on and the front-and rear platforms are free to receive such tools and extra parts as is usually carried on a railroad spreader. The spreader with its front plow is admirably adapted'for snow plow Work and the operator and crew are comfortably housed in the cab against the weather elements: when carrying on such work. Again-the parts are more symmetrically arranged than heretofore thus properly distributing the weight and providing a better balance thereof so that the car as a whole is more capable of withstanding the heavy strains to which it is subjected in use. The spreader has a more neat and orderly appearance and all controls for the various operations are grouped in the cab in a position most convenient for the operator. Again the spreader which must of course be of a massiveness commensurate with its strength is well within the width tolerance permitted on railroads.
