14 Claims. (01162-2) My invention relates 'to an apparatus for cleaning the ballast of the shoulders adjacent railroad tracks in order to induce properdrainage; the invention more specifically, stated involving a vehicle or car adapted to travel on the tracks (self propelled or otherwise) and provided with adjustable means, operable on the ballastat opposite sides of the track, whereby the ballast is taken up, cleaned, deposited at the track sides and reshaped in its original position at the ends of the track-ties.

The invention also contemplates means which is so mounted and secured on the car that it may be elevated and moved within the vertical planes of the car sides so as not to project beyond the prescribed railroad car clearances when not in use; said means being designed to perform the operations mentioned during movement of .the car along the track and'to uniformly reshape the cleaned shoulder ballast.

The invention also' has for its object the provision of apparatus whereby the functions of cleaning, depositing and reshaping can be performed in a shorter period of time than has heretofore been the case and consequently at a materially less expense.

The objects and advantages of my invention as above recited as wellas other advantages inherent in the invention will all be readily comprehended from the detailed description'of the accompanying drawings wherein Figure 1 is a top plan view of a railroad car with my approved apparatus mounted thereon, with'the rear end of the car broken away "and the apparatus shown inoperative position and a portion shown in section.

Figure 2 is a sectional end elevation as viewed along the line 2--2 of Figure 1.

Figure 3 is a sectional elevation taken on the line 3-3 of Figure 2 looking in the direction of the arrows, withcertain portions broken away and shown in section. 7

Figure 4 is a side elevation of the forward end of the car and apparatus with the forward car truck omitted.

Figure 5 is a longitudinal sectional view taken on the line 5-5 of Figure 3 looking downwardly.

Figure 6 is a detailed perspective View of one of the grizzlies of my apparatus.

Figure '7 is a perspective view with portions broken away and shown in section.

My invention is intended to clean the ballast of the shoulders at opposite sides of a railroad track and to deposit and reshape the cleaned ballast in proper position adjacent the ends of the ties of the track; the apparatus preferably involving a railroad car of the flat car type with portions of its deck at opposite sides of the center sill and intermediate the endsof the car out out to permit the apparatus to be swung outwardly and downwardly into operative position.

' In the specific embodiment of the-invention illustrated in the drawings, l5 represents a portion of the car deck whichgintermediate the ends is inset or cut away to the centensill IS; the wheels of the forward truck of the car being shown in dotted lines in Figure 1,- and the rail supporting ties shown in dotted lines at 'IT in Figure I and in fulllines in Figure 2. f

The apparatus involves a gallows frame consisting of suitable'uprightsor posts l8 of predetermined height and extending down'wardlybetween thetwo channel members of the center sill [6 to which they are suitably secured; the posts l8 being arranged at opposite endsof the recesses in the car deck and the tops of the posts preferably connected by a suitable top plate or angle bars as-indicated at IS in Figure 2, while the lower ends of the posts, beneath the car deck l5, are provided with suitable brackets 20 to which the inner ends ofthe links or arms 2| are pivotally connected so as to swing through vertically disposed arcs. The uprights I8, intermediate their ends, are also provided with laterally disposed brackets 22 located a distance above the car deck, see Figure 2 to provide pivotal support for the links or arms 23.- I I v The outer ends of the arms 2| and 23 are piv 'otally connected to a box-like skeleton frame 24 consisting of the longitudinal members 24 tiebars 24 and cross-bars 24} 'Similar frames with associated elements areemployed on both sides of the car, as shown in Figures 1 and 2,'and these frames (which are constructed of channel bars) are preferably raised and lowered by means of pneumatic or hydraulic cylinders and pistons arranged at each end of each frame as shown in Figure 1; the cylinders 25 at one of their ends are pivotally secured to one of the cross-bars or members 24 of the frames while the outer ends of -the pistons 26 are pivotally connected to the gallows frame adjacent the top thereof as shown in Figure 2. The upper ends of cylinders 25 are intended to receive pressure medium from a suitable source of supply .by means of hoselines as indicated at 21 in Figure 2; the pressure medium being introduced intermediate the end wall of the cylinder and the piston-head when it is desired to lift the frames upwardly and within the vertical planes ofthe car sides the upward and inward swinging of the'frame being induced by the pivoted links or arms 2|,

23; the frames in Figure 2 being shown in lowered operative position. v

The forward ends of the frames (namely the ends to the right in Figures 1 and 3) are provided with spaced apart cross-bars 25 (seeFigure 1) between which a plurality of depending scarifiers 28 are mounted whereby the shoulder ballast is stirred and loosened; the scarifiers being arranged in sufficient number transversely v, of each frame 24 in keeping with the width of the shoulder. q s W The forward ends of the frames rearward of the scarifiers 28 are each provided'with a rearward the car and hence adjacent theendsof the tiesi]; the blades 29 (preferably somewhat tapered toward the lower ends as shownin Figure stationary frames 24 and extending throughout ;as shown in dotted lines at the left in Figure 2; ly sloping flange 42, while the lowerend of the closure plate terminates in or is provided with a rearwardly and downwardly sloping dirt guide plate 43 adapted to direct the dirt, separated from the ballast discharging from the buckets,

onto conveyor means later to be described; it being understood that the arcuate closure plate 4| and dirt plate 43 extend throughout the width of the ballast elevating wheel; the plates 4| and 43 however,, being fixedly secured to the stationary frame 24.

.Immovably secured to the upper rails of the the width of the wheel is a vertically disposed r the flanged-end 42 of the closure plate 4| to pro- 3) plow out and guide thescarified ballast towardthe center beneath the frames 24. The outer sides of each frame 24 at its bottom are provided'with depending guide plates 3| whereby the ballast plowed out by the blade 29 and scarifiers 28 is confined to the path of ballast pick-up and elevating mechanism hereafter de-, scribed. V The lower ends of frames 24 at the rear ends of the guide plates 3| are each provided with a downwardly and forwardly sloping scoop 32 arranged transversely of the frame 24 and terminating at its upper end in a rearwardly sloping guide plate portion 33, see Figure 3; the scoops 32, extending to the bottoms of the guide plates 3|, are adapted to cut beneath the ballast and deliver it to the elevating mechanism now to be described.

Rotatably mounted in each box-like or skele ton frame 24 is a ballast elevating wheel composed of two spaced apart annular plates 34 between which a'plurality of triangular shaped ballast elevating buckets 3 5 are mounted; the sides of the buckets being suitably connected to the annular side plates 34; the buckets as is apparent from Figure 3, being open at opposite ends so as to receive the ballast from the scoop 32 and the guide plate 33 during counter-clockwise rotation of the wheel as viewed in Figure 3, with the car moving forwardly or to the right in said figure. s V

The outer sides of the wheel side plates, adjacent the inner perimeters, are provided with an-' nular racks 36 with which the gears 31 mesh;

the gears 31 .being journaled in suitable bear-.

ing blocks as at 38 which are mounted on the stationary frames 24. I prefer to employ a rackand-gear drive at both sides of the wheels to avoid improper thrusts; the gears 31 being driven at a predetermined speed by any suitable power imparting mechanism. 7 l V The elevating wheels are rotatablysupported by a plurality of flanged guide wheels 39 supported on the stationary frames 24 so as to engagethe inner perimeters of the wheel side plates 34 at circumferentially spaced points as shown inFigure3. I

Secured within each stationary frame 24 are I oneor more side plates 40; and between; the

is an arcuate closure plate 4| (see Figure-3) whose upper edge is provided with a downw ardvide a hopperlike structure for guiding the ballast," discharging .from the upwardly moving vibrate as a result of the jars encountered during rotation of the elevatingwheel and forward movement of the car. The grizzlies or grilles are of a well known construction consisting of parallel and closely arranged bars or rods 45 with a connecting plate portion 45 at the upper ends thereof (as shown in Figure 6) which is secured to the side plates 40, while the other or'lower ends of the rods 45 of the grille are free to vibrate; 'the grizzlies being so arranged that the ballast will discharge from the upper grille or grizzly onto the next succeeding grizzly, causing the dirt to be separated from the ballast and to drop between the grille and onto a transversely traveling conveyor to be described. Iniview of the fact that the buckets during their travel past the hopper formed by the flange 42 of. closure plate 4| and bafile plate 44 are not in'position to completely discharge the ballast, I prefer ,to provide a second series of grizzlies 46, similar in construction to grizzlies 45 and similarly mounted and arrangedlin a suitable downwardly sloping manner so as .to discharge the cleaned ballast through the rear downwardly rotatingportion of the elevating wheel and onto the track shoulder.

Disposed transversely through the lower part of the wheel and beneath the grizzlies is a belt conveyor 4'! whose rollers are suitably supported on the stationary frame at opposite sides of the wheel; the conveyor to be driven in any suitable manner and traveling toward the outside of the frame so as to deliver the dirt onto the earth shoulder beyond the ballast shoulder which is located beneath the frame and wheel.

' In order to-prevent the dirt separated by the upper tiers ofgrizzlies falling onto the lower tier I provide additional dirt receiving hoodshape plates 48 arranged within the wheel and disposed between the grizzlies 45 and 46; the plates being secured to the stationary frames and sloping downwardly toward the opposite sides of the frame and discharging into the vertical passages formed between spaced side plates 40,

'50vv of the frame; the lower ends of theinner 'vertical passages having. inwardly sloping baffles 50* 'which deliver the dirt onto the conveyor belt 4'! which in turn discharges the dirt onto the earth shoulder beyond the ballast shoulder.

As shown in Figure 3, the buckets 35 after by a pair of circumferentially spaced baffle plates The cleaned ballast drops from the lower griz-- zlies 45, 46 between the buckets 35 at a point rearward of the ballast take-up position of the wheel, passing down through the defined. channel formed by the two annular side plates 34 of the wheel and is deposited on the track shoulder rearward of the wheel where it is properly spread and shaped by an angularly disposed blade 5| whose lower edge is sheared or cut away in a rearward and upward manner, as more clearly seen in Figure 3.

The ties of railroad tracks vary in length from scarifiers 28, plates 23 and 3|, a scoop 32, elevating wheel and grizzlies and the ballast shaping blade 5|, to the rear of the elevating wheel, whose drive gears 31, namely the gears 31 of the two wheels, are preferably driven by separately controlled means so as to permit the two wheels to be driven at different speeds when desired and the ballast shoulders on both sides ofthe track simultaneously cleaned and replaced during the forward travel of the car and the separated dirt deposited on the earth shoulders beyond the ballast shoulders so that proper drainage away from the ties on both sides of the track may be proeight feet to nine feet and in order that the scarifiers and the take-up scoop adjacent the pick-up position of the-elevating wheel. I therefore provide the forward end of the vehicle or car (see Figure l) with a rearwardly slanting scraper blade 52, suitably supported from the car underframe as for example shown in Figure 4, and preferably with a number of concavoconvex discs 53, 54, 55, arranged at an acute angle relative to the car side, with their concaved sides disposed away from the track so as to throw the ballast outwardly.

Blade 52 is mounted to clear the end of a nine foot tie by approximately one inch and is adapted to plow out ballast from the end of a nine foot tie and leaves a vertical ballast face approximately seven inches from the end of an eight foot tie.

Disc 53 then plows out a two inch cut from the vertical face of the ballast left by blade 52; disc 54 plows out another two inch out; while disc 55 plows out the remaining two inches at the end of an eight foot tie.

The discs are substantially similar to those of a disc cultivator except that discs 53, 54, 55 are provided with blunt perimeters and the hubs of the discs are secured to the end of links 56, 51 and 58 whose upper ends are pivotally secured to the car underframe as shown more clearly in Figure 4. 'As the links are pivotally connected to the car frame it is apparent that the discs which encounter the ties or operate between them may ride over the tie-ends and by reason of their blunt perimeters will not cut into the ties.

With the inset arrangement of the discs my improved apparatus adapts itself to varyng conditions encountered along a railroad right-ofway with some ties eight feet and others nine feet in length; the inset spacing between the discs corresponding to the difference in tie length mentioned.

With the concaved sides of the .discs arranged in the rearwardly and outwardly slanting manner, the ballast intermediate and at the ends of the ties will be thrown toward the center of the ballast shoulder and in line with the scarifiers 28 and pick-up scoop 32 and hence in position for the buckets of the elevating wheel.

It will be understood that both sides of the car are provided with similar elements, namely with vided. a l

The ballast pick-up wheels preferably are driven by a source of power independent of the power for driving the car.

For example, the car may be provided with a suitably driven electric generator indicated at 60 having current. conducting cables 6| leading to motors 62 (one for each pick-up or bucket wheel) suitably mounted in the swinging frames 24, with the outer ends of the armature shafts of the motors provided with sprocket wheels for driving sprocket chains 63 which in turn drive sprocket wheels 64 secured to the inner ends of the shafts 31 of gears 31 which mesh with the annular racks 36 of the bucket wheels; any suitable means being employed to control the speed of rotation.

Likewise, any well known means may be employed to drive the dirt conveyors 41' at proper speed; the outer rollers of the conveyors'constituting the driving'shafts or rollers which are provided with suitable bevel gears as shown at 65 which in turn are driven by bevel gears 66, whose shafts are provided with gears 6'| which mesh with the annular racks 36 of the bucket wheels.

As is apparent, the flexible driving connections between the source of power and the motors permit the frames to be swung upwardly as indicated in dotted lines in Figure 2', when the apparatus is not in use, by means of the cylinders 25 and their pistons 26, operated by a suitable pressure medium supply mounted on the car.

In actual practice, I employ a Diesel engine indicated generally at 68 for driving generator 60, but other suitable power generating means may be employed if desired.

The exemplification shown and described is believed to be the best embodiment of the invention but certain modifications are possible without, however, departing from the spirit of my invention as defined in the appended claims.
