Specification of Letters Patent.

Patented Oct. 1'7, 1905.

Application filed February 18, 1905. Serial No. 246,208.

'1'0 a whom it may concern:

Be it known that I, GRAHAM H. CRAVENs, a

citizen of the United States of America, residing at De Queen, in the county of Sevier and State of Arkansas, have invented certain new and useful Improvements in Apparatus for Ballasting Railway Road-Beds; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others to make and use the same, reference being had to the accompanying drawings, forming a part of this specification.

The object of the invention is to convey the ballast upon the sides of the road-bed beneath the superstructure in advance of the deposit of the ballasting material between the ties, and is an improvement upon the invention as shown and described in application for Letters Patent filed by me in the United States Patent Office on the 6th day of May, A. D. 1904, Serial No. 206,699.

The invention consists in the novel construction and combination of parts, such as will be first fully described and then specifically .pointed out in the claims.

In the drawings, Figure 1 is a side view in elevation of the improved railroad-ballasting apparatus,show ing the'railroad superstructure elevated in position above the road-bed and the improved ballast conveying and leveling devices upon the forward end of the apparatus. Fig. 2 is a plan view in detail of the forward extended end of the platform of the car, showing portions of the elevated track superstructure and the ballast conveying and leveling devices beneath the superstructure. Fig. 3 is a view of the forward extended end of the platform-car, showing the novel devices applied thereto and leveling devices beneath the superstructure. Fig. 4c is .a view of the upwardly-extended end of the adjusting-beams, showing the novel devices for adjusting the same.

Similar numerals of reference indicate corresponding parts in all the figures of the drawmgs.

Referring to the drawings, 10 represents the platform of a vehicle or car, which is shown mounted at its forward end upon the flanged track-wheels 12 12 and at rear end upon the track-wheels 14: 14:. Upon the forward end of the platform is a forwardly-extended frame for supporting the devices for raising the superstructure of the railroad and also the improved ballasting and leveling devices constituting the present invention and which consists of the longitudinal beams 15 15, the rear ends of which are connected with the vertical sides of the platform 10 and the forward ends are projected horizontally the proper distance to support the superstructure raising and ballast-conveying devices and are rigidly connected with a forward transverse beam 16. On the under surface of the forward ends of the beams 15, a short distance rearwardly from said ends, is an I-beam 17 ,which is supported by straps 18, connected with the under surface of the beams. Upon the forward end of platform is an upright structure or frame 19, secured rigidly to the platform, from the upper ends of which extend the supporting truss-rods 20, which are connected with the forward end of the longitudinal beams 15 15.

In rear of the platform-car is a materialconveying car 21, which is coupled thereto, both cars being mounted upon the track-rails 22, which are supported by the cross-ties 23, and said ties and rails form the superstructure of the railroad-bed, the portion of the road-bed 24: directly beneath the cars being raised to the proper level and ballasted, the cross-ties and rails laid in position, and the ballast completed between the ties. This latter operation formed the subject-matter of the previous application, and the devices performing the operations of ballasting the roadbed and tamping the material, as well as the devices for elevating the superstructure of the railroad road-bed, will be briefly alluded to.

The material in the conveying-car 21 falls by gravity into conveyer-buckets 25 on the endless conveyer-chain 26, which passes over the guide-rollers 27 27 on the under surface of the car, thence over a wheel on the shaft 28 on the elevated frame 19, on which shaft is a band-wheel 29, over which extends a belt 30, driven by the band-wheel on the shaft of a stationary engine 31 on the rear end of the platform, power from which through the belts 32 conveys power to the axle of the forward car-wheels 12 of the platform-car. The engine also supplies power to an air-compressor 33, which in turn conveys compressed air to the material-tamping cylinders 34 beneath the forward end of the car, and also to the cylinders of the air lifting-jacks 35 36, the latter jacks being mounted on the rear truck 37, which is narrow in width and movable on the inner track-rails 38 on the extended portion or frame on the forward end of the platform 10 of the car. The jacks 35 are within the truck-frame 38, mounted on the outer parallel track-rails, so that these truck-frames when moved on the track-rails will telescope with each other. Upon the piston-rods of the jacks are chains 39, and upon the lower ends of the chains are rail-grasping books 40, which grasp the rails and by means of which and the chains the superstructure of the railroad road-bed is raised in position above the bed of the road. For the purpose of the present invention upon each side of the forwardlyextended frame is rigidly connected a guideframe 41, consisting of vertically-arranged channel-beams 42 42, one of which is near the forward end of the frame and the other a considerable distance rearwardly from said end. The upper ends of the beams extend a short distance upwardly, above the line of the beams 15, and the lower ends extend a like distance below the line of the under surface of said beams. The upper ends of the beams are connected by a horizontal bar 43, upon which are outwardly-extended shaftsupports 44, in which is journaled a rotary shaft 45. In the channel-beams 42 are slidingly arranged the separate channel-beams 46 46, the lower ends of which beams extend downwardly beneath the level of the railroad superstructure. The upper ends of the frames are connected by the transverse bars 47, which are parallel with each other. Near the lower ends of the bars 46 is a horizontal bar 48, connected rigidly with the inner surface of said beams. On the inner surface of the sliding channel-beams 46 are racks 49. Upon the ends of the rotary shaft 45 are the cog-wheels 50. Upon the shaft 45 is a shaft-operating wheel 51. Upon the inner ends of the beams 46 are downwardly-extended pivots 52.

53 represents the winged ballast gathering and spreading plates, upon the rear surface of which are the sockets 54, which receive the su pporting-pivots 52 on the forward beam 46, thelower portion of the plates being bent outwardly and forwardly at an angle to the beam 46. The plates 53 are similar to an ordinary plowshare and project outwardly the required distance, the winged portion extending inwardly and rearwardly at an angle to the track-rails beneath the railroad-ties a considerable distance, and these portions are braced by the rods 54 extending to the connectingbar 48 on the lower end of the slidable channel-beams 46 and detachably connected therewith.

In rear of the plates 53 are the leveling devices, which consist of the narrow plates or bars 55, upon the rear surface of which are the sockets 56, which receive the pivots on the lower ends of the sliding channel-beams 46 in the rear portions of the frames. These bars extend forwardly and inwardly at an angle to the track-rails and are movably connected together at their inner ends. These bars are braced by rods 57, connected therewith and removablyzconnected with the bar 48 on the lower beams 46.

In the construction of the road-bed the ballasting material is distributed upon the sides of the road-bed and also supplied to the car 21. In the forward movement of the car the quantities of ballasting material in advance of the winged plates 53 upon the side of the road-bed are conveyed and spread by said plates upon the road-bed, and the leveling bars or plates 55 level the material to the grade desired, upon which the superstructure is laid, and the ballast from the conveyers 3O falls through the conveying-spouts 59 to the ties, and the tamping devices 34 complete the work of tamping the material between the ties. When it is desired to adjust the position of the plates 53 upwardly or downwardly to provide for the varying positions of the ballasting material upon the side of the roadbed, the wheel 51 is operated, which moves the channel-beams either upward or downward, as may be required. In the completion of the road-bed the rods connected with the winged portions of the plates 53 are detached, the plates are turned on the pivots outwardly in a like manner, and the leveling devices are detached at their inner ends and turned on the pivot'into a position parallel with the bar 48. The wheel 51 being operated, the shaft 45 is rotated, and the channel-beams 46 move upwardly, so as to remove the material conveying and leveling devices above the level of the superstructure.

Such modifications of the invention may be employed as are within the scope of the invention.

Having fully described my invention, what I now claim as new, and desire to secure by Letters Patent, isp 1.
