and the invention morepartlcularlyrelates to certain features of Construction pertaining to the method of mounting and operating the wings of .the'spreader, whereby the latter may beadjusted and raisedand lowered to meet the requirements of use.

The invention further relates to the formation and method of mounting and operating the supporting arms for the spreader wings, Where y the vertical elevation and lateral distention of the win' s can be adjusted at a. single operation, and y means of pneumatic or other power, thus facilitating the o eration of the device and enlarging its fie d of operation.

The invention further relates to the mounting for permitting vertical adjustment of the s reader wings, and to the arrangement 0 sheaves and rollers, whereby the friction is mimimized, and the adjustment of the wings facilitated. j

The invention further relates to the construction and arrangement of the wing braces and to the mode of adjusting the same; also to the arran ement of pressure cylinders and pistons -or operating the mechanism;

j also to the constructionand arrangei'nent of the entire car body, and the mode of reinforcing the same and securing the various operating structures'thereto.

. The invention finally consists in the features of construction and combinationof parts hereinafter descrlbed and claimed.

In the drawings Figure 1 is a side elevation of the entire spreader, showing the spreaderwing lowered and distended; Fig. 2 a to or plan view'showing', one of the wings disten ed, and the other wing retracted or folded back; Fig. 3 a rear end elevation, showing one of Fig. a cross sectional detail of the car bod showin the arrangement of sheaves on t e forwar bridge; Fig. 5 an inner face view of This invention relates to spreaders for use the mounting for one of the wings; Fig. 6 a cross sectional elevation taken on line 6-6 of Fig. 5, looking in the direction of the arrow; Fig. 7 a top view of the mounting; Fig. 8 a detail, showing the mechanism for raising and lowering one of the supportiiw arms Fig. 9a side elevation of the same, s owing the arm projected Fig. 10 a sectional view of the same and Fig. 11 a detail of the-wing hanger.

Referring to Fig. 1, the mechanism 1s carried by a flat car bed 11 mounted upon forward trucks 12, an rear trucks 13 of the usual character. The car body is preferably I of somewhat less width than the standard, in

order to accommodate the wings when folded alongside the car and ermit the car to travel under standard con itions. The car has -mounted thereon a forward bridge 14 and a rear bridge 15, which serves to sup ort various structures and mechanisms to e hereinafter described. The forward bridge comprises a cross beam lfi, which is supported by means of two pair of divergent uprights 17, which serve to elevate the beam 16 a considerable distance above the car level. The rear bridge likewise comprises across bear-Ii 18, which is supported by means of two-pair of divergent uprights l9. vThe forward] bridge, furthermore, is provided with dia'gonal braces 20, as shown in Fig. 4; Forward of the forwardbridge, on each side of the car, and outside of the edge thereof, is a guide post 21, the lower-end of which is supported within astep 22, shown in dotted lines in Fi 1 which uide osts, above the floor'lcve,,

l g P are space and s'u ported by means of a cross brace23, the en s 24 of which are clamped around the vertical guideposts and serve, in conjunction with the steps, 'to hold the guide posts rigidly in position and out of contact with the sides of the car. The cross br'ace23 is supported, near its ends, upon raised side frames 25, elevated above the car level.

26, whi wings consist of a timber backing 27 and aplate metal facing 28. The inner forward ends of the Wings are entered between inner and outer attaching plates 29 and 30 res ectively, which lates project rearwardly rom and are rigidl y securedto a pivotal mounting head 31, 'as shown in, Fig. 5, which head '18 of enerally rectangular formation having its fower forward corner Each plost serves as a guideway for a wing cut away and above the cut away corner, on

' 33, within which are mounted four sheavesb? means of the central 1pivot bolt 35 and a p u t 3.4, adapted to bear against the o positesides of the vertical guidepost, Whic 1s rounded to permit a swingin movement of the wing as well as an-up an down movement. [The inner and outer sideplates are securedtothe interposed mounting ,head 31,-by means of bolts, or in any other suitable manner; and the wing is secured between the side plates rality of clamping he s 36 arranged in a ring, which arrangement permits the Wing to be raised and lowered upon the pivotbolt35 as a center, and held in adjusted position by the clamping bolts. in addition to the lower bearing sneaves'34 is a guide bearingsheave 37, which is pivoted nut-hm, a mounting 3S embracing the guide post a considerable distance above the wing, which mounting is se cured to the head byinea'ns of a vertical bar 39, which is supplemented by a diagonally extending brace bar 40 which is hooked onto the wing at its outer endand is adjusted by means of a turn buckle 41. This method of pivotaily mounting the wingpermits it to ride up and down the guide post asa bearing, and permits it to swing aroundisnch ostto any position of lateral adjustment, an "these movements will. be ea'eil performed by" rea son of the very c'hnsidera le distance between the upper and lower sheaves, whichobviates any cramping or wedging which. might take widely se arated. i v

Eacho the wings is adapted to beraised and lowered and folded by means of a supporting arm 42, which engaiestm wing at a point about one iourth of t e distance from the front to the rear thereof and'is oi the peculiar shape best shown in Fig. 3. Thesupporting arm, in its entirety, comprises a straight inner ivotal end 43, a supporting portion M, an an upturned attac 1n en the, pivotal end portion by a shoulder 46, and

when the arm is in depressed position, as best shown in Fig. 3, the main or supporting ortion of the arm will bmslightly incline towards its outer end, and will extend in sub stantially transverse relation with res ect to the rearwardly divergent wing with w. ioh it cooperates. The wing is connected with the supporting arm by means of a hanger 47,

best shown in Fig. 11, which comprises a yoke 48, between the arms of which is ivplace if the bearing points were not thus prises amain section behind the rear trucks.

The supporting portion is connecte with,

' scares mg arm'is loosely mounted between cars 51,

which outwardly, roject from a slidable block 52 mounted which arerigidly secured to the end of the forward bridge; The-block is provided, on its rear face, with teeth 54, which cooperate with a dog 55 ivotally rnounted between cars 56 rearwardl y extendin from the guideway 53. The dog is provi ed with a rear" wardly extending lever arm 57, which is ada ted I to be retracted by suitable trip inec anisin 58, which is under the control of the operator. The slidable block 52 and the parts connected therewith are adapted to e raised and lowered by, means of a motor cylinder 59, which is preferably connected with a reservoir 60, which is adapted to be charged with compressed air from the train brake system through a pipe 61,01 is,adapted to be supplied from any other source of comressed air, or other medium under pressure.

within guideways 53,

it is to be understood that the mechanism heretofore described is do licated on both s des of the car, so that furt ier description of these features is deemed unnecessary.

'accommo atefthedivergent position of the wing, Thobraces are of tel'esco lc-formation, and, e'xc'eptfor diilerence-in on th, are

of uniform construction, s o that a cscrip tion;cf. .tlie rear or-longest braces 64will apply. to the othertwo' 'mhe brace 64 comofK-beam formation,

whicli terminates, atits rear end, in a tongue 7 66, which is pivoted between crpss beams 67 which are p'ositioncdlbelow the car body and Between the flanges of the I-beamfifi aremo'unted a pair of oppositely disposed channelbeams 68, which con-.

stitute t e outer section of the telescopic brace- The-channelxbearns are adapted to. be adjusted with respect. to the I-beam, with which they 'coo erate, ander'c. held in adjusted position y means of bolts 69, which arrangement permits the lengthjof the braces to be varied considerably by removing tlie bolts and adjusting the channel beam sections with respect to the I-bcam until the desired length of brace is secured; The on ter ends oFthe channel beams are connected, as shown' in Fig. 2, by means of a tie plate 70 provided with a depending pin 71, and the ends, thus connected, are supported, when in lowered position, within an outer seat 72 on the inner side of the wing, which sent is provided. with a hole 73 adapted to receive the pin or stud 71 when the brace is lowered. It will be understood that the method of mountin and positioning the forward and interm'e'late braces is the same as that pertaining to the outer brace, so that further dcscription of these parts is deemed unnccessary.

The intermediate and rear braces are connected by means of a cross brace 74 of I-bearn formation, which cross brace is pivted, at its ends, between cars 75 on the intermediate and rear braces, which connection is a loose one and permits a slight amount of play or movement when the parts are being raised and lowered, which is essential ,to the proper operation of the arts. In like'mancylinders are located upon thelower cy to convey sheave 82 secured to the beam 16 of the orner the intermediate an forward'braces are connected by means of a square rod or shaft 76, which engages the forward brace near its inner or pivoted end, which arrangement of braces and cross braces serves to firmly maintain the wing in its distended position and enable it to withstand the strainof actual usage. a

Near the rear end of the car are located a pair of lower pressure cylinders 77 adapted to operate the wing supporting arms, and a pair of upper to raise and ower the braces. The upp ward bridge. The sheaves above referred to serve to guide a cable 83, the'end of which is attached to the outer end of the supporting arm. The cable, thus attached, is passed over the upper guide sheave 8 2 and the'lower guide sheave 81, and thence around the actuating sheave 80, the end of the cable being piston 84, having, on its en then fastened to any suitable fixed portion of the car structure. This arrangement is one which gives a movement to the end of the supportin ,arm, twiceas reat as the movement of t e piston. In li e manner the uper cylinder 77, which is preferably smaller tflh n the lower cylinder, is (provided with a a sheave in elinement with a guide sheave 86 which is mounted upon a cross beam 87 on the forward bridge, and the sheave 86 cooperates with a guide sheave 88, suitably secured to the rear bridge, which lower guide sheave is immediately beneath and in alinement with an upper guide upon and secured to the cross beam 18 of the rear bridge. The several sheaves, above referred to serve to guide and actuate a cable 190, the outer end of which is attached to a the cable being. thence passed up over the top'guide sheave 89, thence passed around 'In order to more ressure cylinders 78, adapted sheave 89, which is positioned 91 rigidly secured to the cross brace 41,

the lower guide sheave 88, thence forward around the sheave 86, thence around. the actuating sheave 85, and finally secured to a fixed portion of the car structure. This arrangement gives a movement to the outer end of the cable equal totwice, the movement of the piston. The pressure is-supplied to the respective upper and'lower cylinders by means of pressure supply pipes 92, which are connected with the storage cylinder in any suitable manner.

The outer late 29 of each of the wings is 'providedwit a forwardlyprojecting guard 93 which, when the wing is extended, projects in close proximity with the rail and is adapted to protect the rail against the dir'tor' filling whic might otherwise accumulate. thoroughly insure the rail against obstructions a wedge shaped pilot 94 is employed, which is pivotally mounted at5 the forward end' of the car by means of de pending brackets 95, and the pilot is ada ted to be raised by means of the cable 96 w iich is carried over'a sheave 97 and extends rearwardly and'connects with the lower actuating sheave 80, the cable being of proper length to ive the necessary movement to raise the pi ot away from the track to the desired elevation. securing or bracing the several structures previously referred to, a series of adjustable race rods 98 are employed, which brace and support the guideposts 21 and the forward and rear brid e structures, and the brace rods are 'pre erably provided with turn buckles, so that the entire structure can be tightened up at will.

' In use, with the wing raised and inwardly folded, as shown at the right of Fig. 3, the supporting arm will be pulled up by the retraction of the lower piston rod and the tension of the cable, and when the supporting arm is in this position, the hanger 47 will be supported by the shoulder 46, which will be raised sufficiently, above the pivotal point, to cause the wing to clear the track surface. The wing will also be thrown back in substantially parallel relation with the car by reasop In addition to means forof the fact that when the supporting arm-1s raised the shoulder portion thereof will be in substantial longitul inal alin'en'icnt with the vertical guide post which affords the pivotal mounting for the forward end of the wing.

With the parts in this position, a forward movement of the lower piston rod and actuatmg sheave serves to release the supporting arm, which will descend in substantially the osltion shown in Fig. 3.' Asthe arm is re eased the sheave in the hanger 47 will roll down from the shoulder and onto the main or supporting portionof the arm, and this movement lowers the wing proportionately to its outward or swinging movement. 1 The. provision of the shoulder permits the wing to be supported upon the arm-a considerable distance above its pivotal point, and the shoulder formation provides a specs, when the arm is raised above the shoulder, for the reception of the wing which is thus enabled to lie closely up against the on! body at this point. As the ri-rm is lowered hanger sheave will roll out along the arm until the limit of distention has been reached, in which .osition the main or supporting portion 0 the arm will have e'slight incline toward its outer end, which incline permits the weight of the arm to serve as the means for swinging it into distendedposition. As the arm is thus distended the universal swivel joint of the -h anger will permit the wing to move into its in tended position without j emming or binding of the hanger sheeve which always Ineinteins its proper enga 'ement with the upper surface of the arm. 'ihe pivotal mounting for the g arm, moreover, is one which permits 0. sufhcient horizontal play or movement to socommodate the arm to the different engiesof distention of the Wing, and this movement of the arm, in conjunction with the movement 5 afforded by the universal swivel oint for the anger, gives en easy and uninterrupted movement to the wing which is enabled to swing outinto position hy grsvity when the eim s released. The pivotal mounting for the win on the vertical. post, is one which gives it ee up and down movement, so that the win when the arm is lowered will auto kinetics y adjust itself, both with respect to its verticel elevation and with respect to its 5 angle of distention, and that without binding or crampin which is prevented by the up or and lower s eave hearings for the wing. he wing can be furthermore adjusted, as to its ,vertical elevation, by the motor cyiinder 59, which is'edapted to adjust the pivotal mount ling for the inner end of the arm to any de {sired degree, and the dog 55, which engages with the teeth on the slidable block, serves to "provide e'positive support for the pivotal regardless o the pressure in the ,motor c iinder. The formation of the braces 'is'jone w 'ch permits further adjustment with "respect to the angle of distention ofthe wing, since the length of the braces can be varied, ,asdesired, in order to accommodate the wing to different angles of distention.

The device, as a whole, is one which permits the various adjustments to be readily and quickly made by a single operatonend dispenses with all manual work in operating: the spreader. T he peri s, when'not in use, can be adjusted in such small oonipsss that thewidth' of the entire spreader will not be great-er siibstantially, than ordinary ii at cars, so that the spreader can be run over any track without removal of any of the parts, which, of course, is edvsntagi-x in actual use. The einployrne oiconipressod air from the train pipesarises with the necessity l'or, providing snnidependent eogine or motor for the. spreader and the some time permits sufficient pressure to be stored up in the reservoir so thet the device can he operated even though disconnected fl who train 13,
