RAILROAD WAY CONSTRUCTION AND MAINTENANCE CAR.

Application rifled. December 22, 1920. Serial No. 432,481.

To all whom zf may concern:

lie it known that 1, ROBERT E. BRESSLER, a citizen of the United States, and a resident of Aurora, in the county of Kane and State of Illinois, have invented certain new and useful Improvements in. Railroad Way Construction and Maintenance Cars, of which the following is a specification, reference being had to the accompanying drawings. 7

My invention relates to railway cars used for. grading and road maintenance work, and has particularly to do with cars provided with means for spreading or grading earth along the right of way. Such cars usually comprise wings mounted at one or both sides of the car and connected at one end with the car by pivotal connections arranged to permit the wing either to be extended at a greater or less angle with the car while occupying a horizontal or approximately a horizontal position, or to be raised and swung back substantially parallel. with the sides of the car when not in use. These wings are necessarily made strong and heavy in order to withstand the heavy strains to which they are subjected when in use, and are provided with braces which hold them firmly in operative position and at the same time are so constructed that they do not interfere with the raising and folding back of the wings when that operation is to be performed. The pivotal connections about which the wings swing are also usually arranged to be vertically adjustable so that the height of the inner end of the wings may be regulated to suit varying conditions.

My present invention has to do with cars of this general type and has for its object to provide the spreading or grading wings withauxiliary wings disposed at their outer ends and arranged to retain and carry material along so that it may be deposited in low spots along the right of way or discharged in a fill, in connection with means for holding such material carrying wings firmly in operative position when thegrader wings are extended, and for folding them into a position substantially parallel with the grader wings when the latter are swung back out of 'operative position. The several improvements by which I accomplish this object will clearly appear from the followin g description of the QHlbOtliifiQllt thereof ill lustrated in the accompanying drawings, in

which I have illustrated them asapplied to a car equipped with compressed air actuated mechanism for operating the grader wings which is fully shown and described in my pending application, Serial No. 421,845, filed November 5, 1920. It should'be understood, however, thatthe improvements which constitute the subject-matter of my present application may be applied to the grader or spreader wings of cars equipped with other forms of operating mechanism by which said wings may be swung toward or from the sides of the car.

In the accompanying drawing :Fig. 1 is a side elevation of my improved car showing the spreader wingand material carrying wing at one side thereof in their folded or inoperative positions;

Fig. 2 is a diagrammatic plan view showing the wings at one side of the car folded, and those at the other side thereof extended in operative position, certain parts being in section and one of the forward braces for the material carrying wing being partly broken away;

Fig. 7 is a partial longitudinal section on line '7-7 ofFig. 4;

Fig. 8 is a partial longitudinal seetionpn line 8--8 of Fig. 4:;

Fig. 9 is a partial longitudinal section on line 99 of Fig. 4:; and

Fig. 10 is an enlarged detail, being 'a front view of the wings and their brace's'a-t one side of the car with some parts in section, the view being substantially one as seen from the right of Fig. '2.

Referring to the drawings,10 indicates the body or frame of a car which is of any suitable construction to support the side wings and the operating mechanism thereof. 11 indicates the spreader or grader wings, two of which are provided disposed at opposite sides-of the car, and so mounted that their rear ends are capable of swinging toward and from the car and also vertically. This is best accomplished by connecting the forward end of each wing 11 r to a hinged plate 12 by means of a horizontal pivot 13, the plate 12 being connected by hinges 14 with a sliding block 15 mounted to slide vertically between upright guides 16, 17 secured at the side of the car. By this construction the wing 11 is capable of swinging laterally about the hinges 14 and vertically about the pivot 13, and its forward end is capable of being adjusted vertically. I preferalso to provide a looking plate 18 by which the sliding block 15 may be secured at different heights. For movingthe spreader wing ll into or out of its operative position and holding it in its difi'erent positions, I prefer to employ telescopic braces 19, 20 and 21 provided with compressed air actuated locking devices 22, 23 and 24, and with a compressed air operated cylinder 25 and plunger 26. The

plunger 26 serves to extend the wing 11, the braces 19, 20 hold it in its extended position, and the brace 21 holds it against upward movement except when the several locking devices are released by the'operation of the compressed air actuated mechanism to permit the wing to be retracted and swung upwardly to the position shown in Fig. 1. This retraction and elevation of the wing are accomplished by the operation of a cable 27 one end of which is connected with the upper portion of the wing and the other end with a fixed support. The cable operates over suitable pulleys and is actuated by a pulley 28 carried by a plunger rod 29 operating in a compressed air actuated cylinder 30 shown in Fig. 1. Compressed air is supplied from a reservoir 31, and

suitable valves 32, 33, 34, and 36 are provided for. controlling the admission of compressed airt-o the several compressed air operated devices by which the different movements of tho-spreader wing are controlled. The details of the mechanism which I prefer to employ for this purpose, and which is illustrated in a general way in the drawings, are all fully shown and described in my said pending application,

. and it is not believed to be necessary to illustrate and describe them here, as my present invention is not dependent upon the specific mechanism employed for controlling the operation of the spreader wing, it belng essential only that it be capable of swinging laterally scribed.

Coming now to the improvements which constitute the subject-matter of my present invention,37 indicates my improved material carrying wing, which, as shown in Fig. 1, is similar in shape to the spreader wing 11 and is preferably a rectangular metal plate of suitable dimensions. The wing 37 is-connected between its ends, and

and vertically in the manner deertical hinge 38 so that the material carrymg wing is capable of being folded up against the spreader wing substantially parallel therewith, as indicated by dotted lines in Fig. 2, or of being extended relatively thereto to form a pronounced angle therewith, as shown in full lines in said figure. At its forward end the wing 37 is provided with a plow or earth cutting member 39, as shown in Figs. 1 and 2. The forward end portion of the material carrying wing 37 is held in operative position when extended by a pair of rearwardly converging braces 40, 41, preferably in the form of channel bars, which are connected with the hinged plate 12 by hinges 42, 43, as shown in Figs. 1 and 10, the rear ends of said braces being pivotally connected with sliding plates 44 mounted to slide longitudinally of the inner surface of the wing 37. The arrangement of these plates is best shown in Fig. 5, from which it will be seen that they bear against the surface of the wing 37 and are held in position and guided by separated guide plates 45, 46 arranged in pairs and secured to the wing 37. One of these plates 44 is preferably placed near the upper margin of the wing 37 and the other somewhat below the vertical center of said wing, and they are provided with lugs or ribs 47 which project through the spaces between the guides 45, 46 and serve as means for the attachment of the operative connections of said plates. as indicated by dot ted lines in Fig. 1, the upper and lower plates 44- are connected together by a cross-connection 1S, and the braces 40, 41 are pivotally connected to the lug 47 of the upper plate by a pivot 49, as shown in Figs. 2 and 10. The arrangement is such that when the material carrying wing 37 is in its extended or operative position the pivot 49 is near the forward end of said wing and the braces 40, 41 are approximately perpendicular to the plane of said wing. Said braces, therefore, serve to hold the forward portion of the wing against further outward movement, and when the plates 44 are locked in position, as will be hereinafter described, they also serve to hold the wing against inward movement. When, however, said plates are released so that they are free to slide rearwardly along the wing the forward portion of the wing may be swung toward the spreader wing 11. until it is substantially parallel therewith. In order to permit the wing 37 to lie closely against the wing 11 the brace 41 is preferably offset as shown at 41 in Fig. 2 to provide a space to accommodate the projecting portion of the hinge plate 12. \Vhen the wing 37 is swung into parallel relation with the spreader wing 11 it is automatically locked in such position by means of a fixed shown in Fig. 3.

hook which is secured to the intermediate portion of the outer or forward face of the wing 11, asshown in Figs. 2 and 3, and adapted to project through a slot 51 in the material carrying wing 37 and to be engaged by a latch plate 52 1nounted to slide on the outer face of the latter wing, as best shown inFigs. 3 and 5. This latch plate is fitted between guides 53 and i preferably provided with a slot 52 through which the hook 50 projects when in operative position, as The slot 52 is made long enough so that the latch plate 52 may be n'ioved longitudinally of the wing 37 far enough to permit the book 56 to disengage it, thereby permitting the *ing 37 to be swung outwardly away from the wing 11. The devices for operating the latch plate 52 will presently be described.

The sliding plates 44 are arranged to be locked in position when the wing 37 is extended to its operative position, by means of bolts 54 pivotally connected with the forward end portions [of bell-crank levers 55 which are pivotally mounted upon the outer face of the wing 37 by pivots 56 shown in F 7, the arrangement being such that by pulling back upon the rearwiu'dly-e'xtending arm 57 of said levers the bolts may be moved perpendicularly with reference to the wing 37. When the bolts 54 are in operative position they extend through slots 58 in the wing 37 adjacent to the lugs 47 carried by thesliding plates 44, as best shown in Fig. 7, thereby preventing rearward movement of said plates. When, however, the bolts 54 are withdrawn from the slots 53 by the actuation ofthe bell-crank levers 55 the plates 44 are free to slide rearwardly as the forward end of the wing 37 is swung toward the wing 11. Preferably the levers 55, as well as the operating parts therefor hereinafter described, are mounted between the flanges of channel bars F9 which extend longitudinally of the wing 37, as shown in Figs. 4 and 5, and serve to reinforce said wing.

The bolts 54 and also the latch plate are automatically operated to release the parts which they severally engage when the spreader wing 11 is swung inwardly out of operative position by mechanism which will now be described.

60, 61 indicate the members of a telescopic brace or thrust bar which at its inner end is pivoted at one side of the car so that it is free to swing laterally and vertically, as shown at 62. The member 61 is adapted to slide in the member within certain limits, its range of movement being limited by a pin 63 in the member 60 which passes through a longitudinal slot 64 in the member 61. The outer end ofthe member 61 is connected by a pivot'SOto the outer end of a incl-ting lever 81 which is mounted upon and non-rotatably secured to the lower end of a pivot rod 65 and extends between brackets 66 secured to the rear end portion of the wing 37, which, as shown in Fig. 2, extends some little distance back of the hinge 38. The lever 81 is mounted between its ends upon the rod 65, which extends parallel with the rear edge of the wing 37, and the inner end of said lever is rounded or inclined at its forward side so that when said lever stands substantially perpendicularly with relation to the wing 37 it cannot swing to the left as viewed in Fig. 9, but is capable of swinging to a limited extent to the right. As shown in Fig. 6, the brackets 66 are located near the lower edge of the wing 37 and the pivot rod 65 extends up to near the upper edge of said wing, being journaled in brackets 67 secured at intervals to said wing. Said rod is provided with ri idly attached arms 68, 69, which extend through slots in the wing 37, as shown in Fig. 6. The uppermost arm 68 and the lowermost arm 69 are connected respectively with rods 71 which extend longitudinally of the wing 37 between the flanges of the channel bars 59, asbest shown in Fig. 4, and are connected with the rearwardly extending arms 57 of the bell-crank levers 55. Intermediately of the length of the rods 71 brackets 72 are secured to the channel bars 59 having outwardly projecting flanges 73 through passages in which the rods 71 extend. Between the arms of each. bracket 73 a spring 74 is mounted which at one end bears against one of the flanges 73 and at the other end bears against a collar 75 carried by the rod 71, so that said spring tends to move the rod 71 toward the right as viewed in Fig. 4 and therefore to actuate the bell-crank levers 55 to move the bolts 54 carried thereby into operative position. In like manner the arm 70 carried by the'pivot rod 65 is connected by a rod 76 with the locking plate 52, as shown in Fig. 4, and said rod passes through a guide bracket 77 similar to the bracket 72, and is provided with a spring 78 and collar 79 similar to the spring 74 and collar 75. The spring 78, therefore, tends to move the locking plate 52 to the right, as viewed in Fig. 4, or'in other words to hold it in locking position, as will be clearly understood from'an inspection of Figs. 3 and 4.

When the parts are in operative position, shown in full lines in Fig. 2, the brace member 61 is extended to its extreme position and the pivot 80 lies forward of a line intersecting the pivot 62 and the pivot rod 65. At this time the wing 37 is held in its operative position by the braces 40, 41, which resist swinging movement of said wing in either direction, and also by the brace comprising members60, 61 which resists inward swinging of the forward portion of said wing. When, with the parts in this posidevices controlled by them.

tion, the side wing 11 is swung inwardly and upwardly toward the car the wing 37 does not changeits angular relation to the wing 11 until the brace member 61 is moved into the brace member 60 to the limit of its movement, this inward movement of the brace member 61 being caused by the inward movement of the wing 11. As soon as the outer end of the slot Set in the brace member 61 engages the pin 63, further inward movement of the brace member 61 is prevented, and as the wing 11 continues to swing inwardly the members 60, 61 operate as a thrust bar which acts upon the lever 81 in such manner as to tend to rotate said lever in a clockwise direction, viewed in Fig. 2. This causes the arms 68, 69, 70 carried by the rod to swing to the left as viewed in Figs. 4 and 8, thereby releasing the locking The release of the sliding plates 4% permits said, plates to slide rear wardly along the wing 87 and consequently said wing is free to swing into parallelism withthe wing 11 under the action of gravity and the thrust of the thrust bars 60, 61. \Vhen the wing 37 moves into approximate parallelism with the wing 11 the hook passes through the slot 51 in the wing 37 and into position to be engaged by the latch-plate 52, and as the inward swinging of the wing 37' operates to draw the member 61 somewhat out of the member the lever 81 is relieved from pressure and consequently is free to rock in the opposite direction under the action of the springs 7 4:, 7 8. The latch plate 52 is, therefore, caused to move into engagement with the hook 50, thereby locking thewing 37 in parallelism with the wing 11. lVhen the parts are in this position, as shown by dotted lines in Fig. 2, the outward swinging of the rear end of the wing 37 carries the pivot 80 to the rear of a line intersecting the pivots 62 and 65, and, therefore, when the spreader wing 11 is again swung outwardly toward its operative position the member 61 is first drawn out of the member 60 to the limit of its movement, and when the pin 63 reaches the inner end of the slot 64 further outward movement of the wing 11 exerts a pull upon the lever .81 which tends to rock it in a clockwise direction T as viewed in Fig. 2, thereby operating said lever to move the locking plate, 52 out of engagement with the hook 50. This releases the material carrying wing 37 so that upon further outward movement of the wing 11 the material carrying wing is swung outwardly into its operative position, and this outward swinging of the wing 37 causes the sliding plates 44 to move forward along said wing until they reach the position shown in full lines in Fig. 2. The early part of the outward turning movement of the wing 37 releases the pull upon the member 61 and consequently under the action of the springs 74 the levers are rocked to carry the bolts 54 into locking position. These bolts are bevelled as shown in Fig. 7 so that the sliding plates 44 may trip past them into the locking position shown in said figure.

From the foregoing description it will be seen that the material carrying wing 37 is automatically moved into or out of operative position; that when in its operative position it is locked against movement in either direction with reference to the spreader wing 11; and that when said spreader wing is moved into its inoperative position the material carrying wing is automatically folded against it and is locked in such folded position. So far as I am aware I am the first in the art to provide a material carrying wing operating in this way, and the claims hereinafter made are, therefore, to be construed generically, except in so far as they may be directed to specific features of cmistruction shown and described.
