A Tram/[r Unite This invention relates to improvements in ballast distributing machine for railroads. The principal objects of this invention are:

First, to provide a railway vehicle capable of moving forwardly and rearwardly along a railway to distribute or level ballast along the roadbed while moving both forwardly and rearwardly.

Second, to provide a ballast distributing machine for railways capable of collecting ballast deposited along the sides of a roadbed and uniformly distributing it.

Third, to provide a ballast working machine having side scraping and distributing means that is vertically and laterally adjustable to function over various widths of shoulder area alongside a railway track and which are swingable vertically to a traveling position to provide clearance for the vehicle while traveling to and from work location.

Fourth, to provide an adjustable and flexible mounting for side distributor boxes on a ballast distributing machine which permits the boxes to function while traveling in either direction and which permits the boxes to tilt longitudinally and spill excess ballast therefrom where encountering piles of ballast exceeding the capacity of the boxes to completely distribute the ballast.

Fifth, to provide a ballast distributing machine with a double acting two faced scraper or plow capable of spreading ballast laterally across a roadbed while traveling in one direction and collecting or converging ballast toward the center of the roadbed when traveling in the opposite direction. I

Sixth, to provide a ballast distributing machine having side distributor boxes with ballast working harrows therein that are automatically swingable to operative position upon reversal of the direction of movement of the machine and the boxes.

Other objects and advantages of the invention will be apparent from a consideration of the following description and claims. The drawings, of which there are three sheets, illustrate a highly practical form of the distributing machine of the invention.

FIG. 7 is a fragmentary vertical cross sectional view through the ballast collecting harrow taken along the plane of the line 7-7 in FIG. 5. i

' FIG. 8 is a fragmentary vertical cross sectional view Bfi llfih Patented Aug. 7, 1962 through the adjustable support for the front plow of the machine taken along the plane of the line 88 in FIG. 3.

As appears most clearly from FIGS. 1, 2 and 3 the distributing machine consists generally of a mobile carriage having a bed or platform 1 supported upon flanged wheels 2 for movement along the rails 3 of a railway. A driving internal combustion engine 4 is mounted on the bed in front of a suitable drivers cab 5 and connected through suitable gearing 6 to the axles 7 for driving the wheels 2. Vertically adjustably mounted on the front end of the carriage is a double faced scraper or plow 3 and laterally swingably and extensibly mounted on the sides of the carriage are a pair of side distributor boxes indicated generally by the numeral 9.

Considering first the construction and mounting of the plow or scraper 8 as shown most particularly in FIGS. 1, 2, 3 and 8, it is pointed out that the plow has a forwardly facing convex V-shaped face 10 connected to and spaced from a rearwardly facing concave V-shaped face 11. The faces 10* and 11 are notched as at 12 over the rails 3 to permit the plow to be lowered to below the level of the rails when desired. Connecting plates 13 connect the

opposite faces

10 and 11. Certain interior connecting plates are provided with upstanding ears 14 supporting vertically spaced pairs of pivots 15. Pairs of vertically spaced parallel arms 16 connect the pivots to vertically spaced pivots 17 carried by brackets 18 on the front end of the platform 1. Movement of the plow is thus guided in a vertical plane. Hydraulic cylinders 19 pivotally connected to cars 20 on the carriage have their piston rods 21 extended upwardly and forwardly and pivotally connected to cross bars 22 extending between transverse pairs of the arms 16. Hydraulic pressure delivered to the cylinders 19 through conduits 23 from suitable supply and control elements not illustrated actuates the cylinder to adjust the elevation of the plow to the desired position.

Considering the construction and mounting of the side distributor boxes 9, it is pointed out that the boxes consist of inner side walls 24, outer side walls 25 and outwardly converging end walls 26. The end walls as are shallower or narrower than the side walls and have hinges 27 on their lower edges to which scraper blades 23 are swingably connected. Outwardly converging brace rods 29 extending between the inner and

outer sidewalls

24 and 25 at the longitudinally outer sides of the scraper blades act as stops to limit outward swinging motion of the scraper blades 28. Thus as appears most clearly in FIG. 5 with the carriage and distributor box advancing in the direction of the arrow, the forward scraper blade will swing inwardly in passing over piles of ballast distributed along the roadbed but the rear scraper blade 28 will be stopped by the rear rod 2? to function as a scraper to level the ballast and scrape excess ballast inwardly toward the rails.

Laterally adjustable wings 30 carried by vertical hinges 31 on the ends of the outer side plate are adjustably positioned by links 32 connected to the brackets 33 for intercepting and collecting ballast deposited further outwardly from the rail along the shoulder of the roadbed.

In order to collect or accumulate sufficient ballast along the inner sides of the boxes 9 where it is normally more needed, the boxes are provided with collector barrows having disks 34 mounted on yokes 35. The yokes 35 have upstanding threaded pins 36 vertically adjustably received in sleeves 37. The pins are clamped in adjusted position by lock nuts 38 and the sleeves 37 are fixedly mounted in support arms 3% pivoted on pins 40 secured to the middle of the inner side walls 24 of the distributor boxes. The outer ends of the arms 39 are slidably and automatically adjustably supported by ways 41 formed by slots in the outer side walls 25 of the boxes. The arms 39 will automatically swing to a rearwardly inclined trailing positrated, functions to raise and lower the boxes 9 as desired.

In order to permit vertical and lateral adjustment of the position of the distributor boxes in their outwardly swinging horizontal working position, the inner corners of the boxes are provided with yokes 4'7 faced laterally inwardly toward the sides of the carriage l. The ears of the yokes 47 define slots 43 that are generally vertical in the working positions of the boxes and which receive pivot pins 49 extending horizontally and longitudinally of the carriage from the lower ends of piston rods 56 associate with hydraulic cylinders 51. The cylinders 51 are positioned within and supported by tubular uprights 52 positioned adjacent the four corners of the carriage bed 1.

The lower ends of the uprights 52'; are rigidly connected to and supported by tubular slides 53 which extend transversely inwardly of the carriage into tubular bearings or slide ways 54 supported along the underside of the bed by depending plates 55 and 56 secured to the

longitudinal frame members

57 and 58 as appears more clearly in FIG. 4. The tubes 54 thus support the slides 53 and upright tubes 52 so that the hydraulic cylinders 51 are supported from the carriage to vertically adjustably support the pivot pins 49. The pivot pins 49 in turn support the side distributor boxes at various levels as the pivot pins 49 are moved upwardly and downwardly in slots 59 provided therefor in the upright tubes 52. Particular attention is invited to the fact that while the position of the pivot pins 49 establishes the general elevation at which the side distributor boxes will be positioned, the vertical position of the slots 48 in the yokes 47 permits the trailing ends of the boxes to move upwardly and ride over piles of ballast when the accumulation of ballast in the boxes and against the trailing scraper blade 28 exceeds the capac ity of the box and the machine to advance the box.

In order to adjust the position of the distributor boxes laterally to reach further out along the shoulder of the roadbed, the tubular slides 53 supporting the tubular uprights 52 are provided with racks 60 exposed or accommodated by slots 61 in the tubular slide ways 54. The racks 65 on the forward and rearward slides 53 on each side of the machine are connected by a longitudinal shaft 62 having gears 63 secured thereon and meshing with the racks so that the forward and rearward slides move in unison. Hydraulic cylinders 64 mounted adjacent each corner of the bed 1 have one end connected to a bracket 65 on the carriage while the piston rods 66 of the cylinders are connected to bracket 67 on the inner ends of the slides 53. Fluid pressure directed through the conduits 68 forms suitable controls not illustrated, actuates the cylinders to extend or retract the distributor boxes laterally of the machine.

The machine with the collecting and distributing elements just described not only has a high capacity for distributing uneven piles of ballast deposited at various positions along a railway roadbed but has the capability of automatically operating during forward or reverse motion along the railway to distribute ballast by successive operations when the accumulation of ballast exceeds the capacity of the machine to distribute and level the ballast with a single pass.

The machine illustrated is particularly adapted and desirable for use in the distributing or placement of new ballast, that is, new or added ballast on any original track construction but it should be understood that it is adapted for use in reworking ballast on the shoulders of railway track beds. While the harrow discs 34 and scraper blades 28 are illustrated in connection with what is here termed as distributing boxes, it should be understood that the longitudinal members are not necessarily boxes in the sense of conveying ballast as distinguished from working it and levelling it.
