Claims. (Cl. 37-105) This invention relates generally to improvements in railroad spreaders, but relates more particularly to improvements in the main wing and in ditcher mechanism carried by the main wing.

Spreader main wing constructions, as heretofore designed, have been constructed of castings, which result in a heavy wing structure, and also one which cannot readily be modified to comply with the particular customers specification. Fabrication and machining are also difiicult and expensive.

Ditcher mechanism of this general type has also been in use heretofore, but is of such construction that it is open to certain objections. For example, such prior ditcher mechanism comprises many moving parts, including in some instances chain driven parts which, in practice, give trouble by premature breakage.

Again certain prior constructions are such that it is difiicult to maintain lubrication of bearing surfaces; the ditcher actuating mechanism comprises screw threaded shafts which are subject to premature breakage, as well as being slow in operation. 7

In certain prior mechanism for this purpose the ditch section or blade has been of cast construction, subject to distortions which prohibited movement in close tolerances.

The general object of this invention is to provide a main wing and ditcher mechanism which shall be of simplified construction involving a lesser number of parts and one which, at the same time, shall be easier to construct and maintain.

A further object of the invention is to provide a main wing and ditcher construction which can be made lighter in weight without sacrificing the necessary strength.

Again, it is an object of the invention to provide a construction which will permit of greater tolerances inconstruction and operation and one in which the operating mechanism for the ditcher blade can be smaller in size, thereby permitting more clearance between the main spreader wing and the car body when the main wing is folded to the side of the car.

I Other objects of the invention are to provide structure sodesigned that the accumulation of dirt and other foreign matter in the main wing cavity, when the ditcher member or blade is exposed, is minimized; to provide structure which will enable the ditch to be out without disturbing the bank or berm, and to provide hydraulic operable means for actuating the ditcher member or blade in such manner that locking in increment positions is possible.

The above named objects of the invention, as well as other features, will more fully appear as the specification proceeds.

In the drawings:

Figure 1 is a side elevationof a railroad spreader, the main spreader wing of which is provided with a ditcher structure embodying the preferred form of the invention, the ditcher section or member appearing in its in- 2 operative retracted position relative to the associated spreader wing.

Fig. 2 is a view in elevation, on a scale enlarged over that of Fig. 1, of the rear side of the main spreader wing, showing the ditcher member in its operative projected position and further schematically showing the hydraulic circuit for moving the ditcher section between its inoperative and operative positions relative to the spreader wing by which it is carried.

Fig. 3 is a horizontal sectional view through the spreader wing, as taken on the line 33 and on a scale over that of Fig. 2.

Figs. 4 and 5 are vertical sectional views through the spreader wing, on the scale of Fig. 3, as taken on the lines 44, 5-5 respectively of Fig. 2.

Fig. 6 is a view in side elevation of the ditcher blade, on the scale of Fig. 2 and will be more fully referred to later.

Referring now to that embodiment of the invention illustrated in the accompanying drawings, 10 illustrates as a whole a railroad spreader in the form of a car having front and rear sets of wheels 11 and 12 respectively, adapted to travel on the rails of a railroad track 13.

The car has a deck 14 secured to the car underframe, which may be of conventional construction for cars of this type and which is, therefore, not shown in detail.

At the front of the caris a plow structure 15 which forms no part of the present invention. A suitable distance rearwardly of the front plow of the spreader is an upright post or column structure 16 and an associated main spreader wing 17. It shouldbe understood that a post or column structure and associated wing is provided on the opposite side of the car but since they are of like construction they have not been illustrated.

The main wing 17 is hingedly attached to the post or column 16 by a hinge 18, thus adapting the wing to be swung outwardly and retracted by known or conventional means. Also, the wing may be raised and lowered under the control or'actuation of the fiuid cylinder or engine 19. Additionally the main wing 17 is pivoted on a horizontal pivot 20, on part of the hinge structure 18 so that the main wing can 'be swung upwardly and downwardly under the control of actuating mechanism 21 which may be of conventional or known construction.

Extending between the inner side of the main wing and the car body or frame are wing braces 22 which are or The main wing structure The main wing 17, as here shown, comprises inner and outer portions or parts I and 0 between which is located a portion D for the support and reception of the ditcher blade or member.

On the outer face of the wing and extending the full length thereof is a sheet metal plate member 25, the inner side or face of portion I being constituted of a sheet metal plate member 26 connected to the plate 25 by means of a plurality of structural channel shaped members 27, 28, 29, 30, 31, 32 and 33, which extend generally lengthwise of the frame (see Figs. 2 and 4). Additionally there are upright channel members 34, 35 and 36 which, in general, constitute the portion I into a boxlike part or section. It will be understood that the plates and structural members and plates are secured together as by welding, so that an extremely rigid, strong structure results. I

The end portion 0 of the main wing includes upright channel members 37 and 38 bounded at the top by channel member 27 which extends inwardly across the top of theportion D .andjisan extension of the channel member 27 of section I.

The plate 25 is affixed to the channels 37, 38 and 39 and constitutes the outer face of the wing.

Th s ru t of in mediate Sect on wil be best understood by reference to Figs. 2, 3 and 1 Itwill. be observed .thattheplate forms the outer face of the section. The dimension of the top part .of the section D from. front face to .rearface is the same as that-o the section I. However, the inner plate 40 extends downa wardly but partway terminating ;a short distance below thechannel fmember 41.

Aifixed to the face plate 25 and. extending frqmthe underside of. the channel member 41 is a plurality of vertically spaced channel members 4 2.similar to the nern ber 41, but arranged with the flange portions thereof in substantially perpendicularrelation to the flange portions of the. channel 41. Affixcd to the base portions ofthe channels 42 is a plate member 43.

Extendinglongitudinally of the wing 17 along the-bottom thereof isa beam-like structure designated as a whole by the member 44. It comprises upper and lower angle members 45 and 46 respectively, a channel member 47 and a filler plate 48 which are rigidly secured together, as .by .welding, 10 form a boxlike structure, as best shown in Fig. 5.

The end portions of the beam 44 extend. across the lower parts of the sections I and O, theface parts 45 and 46 of angles 45 and. 46 contacting the same and being secured permanently thereto.

As .clearly appears from the foregoing there is thus provideda -recess portion on the rear side of the main wing intermediate the ends. The portions 45 and 46 of the beam structure being spaced from the plate 43 thus provide-a vertical slot 49 for the accommodation .of the ditcher blade 50.

The ditcher blade mechanism Fig. 2 by means of a pair of links 59.-59, the lower ends:

ofwhich are pivotally secured inthe upper part of the bladeSO- by horizontally disposed pivot pins 60-60, the upper .ends being pivotally secured by pivot pins.61-61.

tothe upper part D of the main wing 17, as best shown in Fig.. 5.

The pivot pins 6161 extend through the plate 40, filler plates 6263, plate 43 and the base or web portion of the uppermost channel member 42, beingheaded .at

opposite ends to complete the assembly.

Inorderto swing the blade there is provided an'hydraw. lic cylinder 64 pivotally secured at 65 to a bracket.6 6, secured to the inner side of the main wing. The piston rod 67, which is secured to a conventional piston memher (not shown) in the cylinder 64, has its lower end. secured to a bracket 68, by means. of a horizontal'pivot member 69. The bracket 68 is rigidly aflixed to the upperpart of the blade 50.

In .thefull line position (Fig. 2) the piston is atthe lower end of the cylinder 64, at which time the blade is.. ,also in its lowest position.

In. order to cause movement of the piston longitudinally of thecylinder 64, means are provided to supply hydraulic flnidunderpressure to one endortheother of the cylinder, depending upon which way it is desired'the .piston shall .move. The means for supplying hydraulic fluid under pressure, and under the control of the operator is schematically illustrated in Fig. 2.

Referring to Fig. 2, 70 is an hydraulic fluid reservoir, and 7.1 a Prime never. cou seled tq pe ate a pump7l- A four way control valve 73 is provided, the spool of which may be shifted, by means of the control lever 74 which is mounted in a position on the car convenient for actuation by the operator.

75 is a fluid line connecting the pump 72 and valve 73. 76 is a return line connecting valve 73 and reservoir 70. Also extending between the valve 73 and-the cylinder 64 are fluid lines 77 and 78.

Thehydr'aulic control circuit is.co mpleted by the pressure relief valve 79 andthe line 80 which is connected to the line 76 leading to the reservoir 70.

The .valve 173 isof the spring pressed typeoperating to return the lever 74 .to the full line position shown in Fig. 2 when ever it is released. At that time all valve ports are closed, thus locking the hydraulic fluid in the system except that when the pump 72 continues to operate relief yalye 79.opens,-permi tting the p mped Ifluid'to return to the, reservoir through line :80.

Assumenow it is desired to move the blade 50upward-: ly, from any position excepting its uppermost position, the control lever 74-is swung to a dot and dash position which moves the valve 'control spool to connect lines -75. and 78. Lines .77 and 76will alsobe connected. In thiscoudition fluid under pressure will flow through line. 78], moving the piston upwardly and retracting the .piston: rod 67, thus causing upward and inward. swinging move. ment of :the ditcher blade.

At the same time lines 77 and 76 .were connected so. that-the fluid displaced by the upward movementrofthe piston can return .to the .reservoir.

1f,- at anytime, it is desired to swing the-:blade. 50

downwardly from any position other-than its lowermost positiontthe lever 74 is swung ;to the other dotted line p osit;io n,.;l'r"ig, 2, thereby connecting lines .75 and 77 .sothat fluid underpressure is supplied to the upper end of the cylinder 64, thus forcing the piston toward the lower end and projecting the piston rod 67 outwardly and.down.-. wardly, At the sametime lines .78.and 76are connected so that the-fluid displaced by the .downward movement of thezpiston' can return to the reservoir.

From the foregoing it will be seen that the ditcher blade may be. moved ,any desired distance betweenits extreme positions and there held against .movementnby the hydraulicfluid which is locked in that .part of the. system between the 'valve -73 and the hydraulic cylinder 64. In this way small incrementsof movement.:can. readily begimparted to the ditcher blade 50 in order to cute ditch ofdesired cross-sectional contour.

General remarks From the foregoingit will be seen that the structure illustrated and described attains theobjects and purposes outlined in the opening of1the specification, as well as others.

The :main wing, being fabricated of conventional structural shapes can be produced and assembled at relatively low cost to produce a light rnain wing of adequate strength.

Furthermore, the structure is one which can be readily modified .to meet the'special requirements of individual. customers- It isnbelieved thesmany :aduantagesxof the main wing and .ditcherrblade construction will be obvious without u e ommen We-claim:
