This invention relates to improvements in Wing` shaft operating mechanisms for railroadfspreaders `and it consists of the matters hereinafter described and more particularly pointed outin the appended claims.

`In railroad spreaders including sidewings for spreading ballast and like operations, each side wing is connected at one endby means of an upright pivot pin to a suitable sliding block arrangement :in an associated side post or column. The wing is` swung away from and toward thecar, about said pin as an axis by `foldingbars connected at one end to the `wing and at the other' end to `arms on `a longitudinally extending shaft journalled on the assop :ciated side of the car. The necessary rotative rocking movement ofthe shaft washeretofore imparted `to said shaft by iiuid pressurecylinders disposed beneath the car deck and extendingtransversely thereof, the piston rodofthe cylinder being connected to the beginning and end of 'an arm on each shaft.v "In such a construction theleverage` of said arm changed in proportion `to the change in the "angular position of thearm on the shaft so that the greatest load was imparted to the operating cylinder at its power stroke,

"thus a great dealof power was absorbed atlthe outsetofoperation, which as is apparent Ais `not a desirable condition. `Again Withothe power cylinders arranged transversely of and on the under side `of: the car deck orframe, they did not readily lend themselves to a ready inspection orrepair and did not permit ofthe best arrangement of parts `of standardapparatus on such `al car of the spreader.:

The primaryyobject of the present invention is toimprove the means by which the wing shaft is turned or rocked and to so dispose the operating 'cylinders therefor that `theymaybeiarranged vertically on the top ofthe car deck," where `they may be readily inspected and at lthesame` time providey for a better distribution and the balance of the associated parts. y

. `A further obj ect of the invention is to simplify the construction of the associated parts and reducethe number thereof to a minimum whereby the cost of production is proportionately reduced and the eiiciency thereof is materially increased.

These-objects of the invention, aswell as others together with the many advantages thereof will more fully appear as I proceed with my specification.

In thedrawingsa-` Fig. 1 is a `vievvin top plan elevation of a railroad spreader embodying my invention.

Fig. 2 is a transverse vertical sectional view through the spreader, on an enlarged scale as taken on the line 2---2` of Fig. 1.

A Fig. 3 is a fragmentary View in side elevation of parts shown 'at the right hand side of Fig. 2. l

Fig. 4 is a. detail vertical sectional view on a further enlarged scale, as taken on the line 4l-1 of Fig. 3. l

Referring now in detail to that `embodiment of the invention illustrated in the accompanying drawings z-1 indicates as a whole the car of a railroad spreader having the usual wheels 2to travel upon the rails 3M?) of a railroad track. The car includes a deck 4 with a wide platform 5 `at the front end and a similar platform 5a at the rear end; the deck itself being narrower than said `platforms to form cut in sides of the car.

`9 in each of which a wing carriage 10 is capable of a guided vertical adjustable movement. 11 indicates the main side wing of the spreader whichis pivoted at its inner or front end to the wing carriage by means of a vertical axis pin 12 so that said Wing may be swung from a position parallel with the sills as shown at thetop of Fig` 1, intola position at an angle to said sills as shown at the bottom of said figure. As the parts associated with each spreader wing on each side of the car are the same, .a description of the parts associated with one wing will suHice for both,

like parts on both sides of the car bearing like reference numerals.

Dependin from each side sill 7, forward of the rear pIatform 5n is a plurality of longitudinally spaced end and intermediate bearing brackets 13 and 14, respectively. The end brackets each include a pair of spaced bearing ears 13a-d3UL while the intermediate bracket includes a single bearing sleeve 14a. Jour-nailed in said ears and sleeve is a longitudinally extending tubular shaft 15 and fixed to the shaft between the ears of each bracket 13 are castings each of which includes a socket 16 extending at less than a right angle to said shaft.l Operatively connecting each socket casting with spaced points on the rear side of the main spreader wing are folding brace bars 17-17 each including inner and outer brace arms 18 and 19 respectively, said brace arms being connected together by a knuckle 20. The inner ends of the brace arms 18 extend into and are pivoted within the sockets 16 by pins 21 arranged at a right angle to the associated shaft 15. The outer ends of the brace arms 19 are iconnected to the wing by brackets and pins 22 as best shown in Fig. 1. This last mentioned connection as well as the socket connectionbefore described permits the brace arms to fold at the knuckles so that the wing may be swung from one position to the other as desired.

23indicates as a whole an upright post arranged in substantially the plane of the intermediate bracket 14, there being one of such posts at each side of the car. Said post comprises a pair of longitudinally spaced u standing angle bars 233--23a which are riveted to the associated side sill. Connecting the laterally arranged flanges of Athe angle bars Von one side of the car with the like flanges of the angle bars on the other side of the car is a pair of cross channels 24-24, said cross channels resting on and being secured to the side and center sills. The top ends of each pair of angle bars forming each post are connected together by pairs of short longitudinally arranged channels upon which engage pairs of short transverse members 26 to form supports for bearing ears 27-27. In said ears are journalled the ends of a short shaft 28 to the middle of which is fixed a sheave or grooved pulley 29. Resting on the top flanges of the cross channels 24-24, to the rear of Veach post 23 is a .pair of short angle bars 24a. Engaged upon and upstanding from said angle bars are fluid pressure c linders 30 each having a piston 31 therein. aid piston has top and bottom piston rods 32 and 33 respectively which extend through suitable stuffing boxes in the respective ends or heads ofthe cylinder. To the top piston rod 32 is connected one end of a cable section 34 which passes over the sheave 29 and to the bottom piston rod is connected a second cable section 35 which is wound or lapped more than a single turn around a grooved sheave or pulley 36 fixed to an associated shaft 15, in the plane of the pulley 29. The cable sections 34-35 are connected together by a turn-buckle 37 whereby they may be maintained taut. The cable section 35 is securely attached to the sheave 36 at one point in its length by clamps 38 arranged in the peripheral part of the sheave and having clampino` nuts 39 arranged in suitable openings in tIie web of the sheave. The cylinders 30--30 are not only secured to the angle bars of the respective posts but are connected to each other in any suitable manner and are operatively connected to a source of fluid under pressure by the usual pipe and hose connection in the manner well known. Preferably such source of fluid under pressure is a compressed air tank 40 carried on the car deck just forward of the posts 23.

In operation, when air is admitted to one end of the cylinder, the piston moves toward the other end thereof and through the connected cable sections, one of which is attached to the sheave 36 as before described, will cause a partial rotation or turn of the associated shaft 15 the leverage on said shaft always remaining constant and in accordance with the air pressure admitted to said cylinder. When piston is moving upwardly in the cylinder, the respective arms of the wing brace are project-ed outwardly into alignment to cause the wing to be projected or swung away from the side of the car and when the piston is moving downwardly the brace arms are folded and the wing is swung toward the side of the car as shown at the top of Fig. 1. By the arrangement described, the action of moving the wing is positive when it is desired to swing the wing in either direction. Should the cable stretch in use, the slack may be taken up by the turn buckle.

While in describing my invention I have referred in detail to various forms and arrangements of the parts thereof, I do not wish to be limited thereto except as may be pointed out in the appended claims.

I claim as my invention 1.
