PATENT OFFICE BERNARD W. BTRAW, OF LIOUNT AIRY, MARYLAND, ASSIGNOB TO AUTOMATIC BALLAST SPREADER CORPORATION, OF WILMINGTON, DELAWARE, A CORPORATION OF DEA- WARE mums non msenaneme BALLAST Application filed August 6,

This invention relates to means for distributing ballast on a railway roadbed.

In the discharge or deposit of ballast on a track ballast cross-section by the use of an ordinary hopper car, substantially all of the ballast in the hopper must be discharged when the hopper door is opened, and said door cannot be closed or controlled during the time the ballast is being discharged, so that the latter is therefore discharged at a substantially uniform rate. Since Widely varying quantities of ballast are requirred at various points along the track, the ballast dls charged from a hopper car must subsequently be moved from place to place by hand labor to form the proper ballast cross-section.

Another objection to the use of a hopper car for depositing ballast resides in the fact that the ballast is necessarily deposited between the track rails and immediately adjacent the ends of the crossties, due to the construction of the car. In many instances, however, it is desirable to discharge the ballast onto the ballast shoulder or into the center ditch when ballasting a double track railway, and for this purpose special ballast cars are provided. The use of special service cars is, however, disadvantageous since said cars are practically limited to this one use and must be hauled great distances as empties after ballast has been discharged therefrom. Moreover, special cars heretofore provided have been subjected to one of the objections resulting from the use of hopper cars in that the amount of ballast distributed cannot be properly controlled and must be manually distributed after being discharged from the car.

In my Patent No. 1,689,694, granted Oct-o-. ber 30, 1928, there is disclosed ballast distributing means for discharging ballast onto a road Way or track at one or more selected points and in the desired amount or amounts. The present invention is, however, primarily concerned with means for controlling the delivery of ballast to form the outside shoulder of the track ballast cross-section. So far as I am aware it has always been necessary heretot'ore to manually handle ballast distributed onto a roadway or track ballast cross-section to form the outside shoulder of the cross-sec- 1927. Serial No. 211,111.

tion, and in the event the ballast has been discharged onto a double track railway, it has been necessary to manually distribute the ballast deposited between tracks in order to properly form the center ditch.

The principal object of this invention is to provide apparatus adapted to be associated with a ballast carrier, whereby ballast may be distributed in the required amount and formed into the desired shape on a particular portion of a railway track ballast cross-section.

Another object is to provide apparatus for receiving ballast from a ballast carrier and for depositing it on the ballast section shoulder in the proper amount required to form the shoulder, whereby the shoulder is properly shaped without the necessity for manually handling the ballast.

Another object of this invention is to provide, for use in combination with a ballast carrier, apparatus adapted toreceive ballast from the carrier and to deposit it in the required amount and form to constitute a balfiist section shoulder or a center ditch, or bot Another object of this invention is to provide a ballast distributing and shaping deviceor dresser for forming a ballast' crosssection shoulder, or a center ditch, said dresser being adapted for use in combination witha ballast spreader.

A further object of this invention is to provide a ballast dresser adapted to be adjustably and removably attached to a ballast spreader.

Another object of this invention is to provide novel ballast spreading and dressing means for use in combination with a railway hopper car, said means being so constructed that the same are operatively associated with said car without the necessity for making any structural changes-in the car, whereby the latter may be employed for other purposes.

A further object of this invention is to provide a novel ballast distributing means whereby ballast may be deposited in a proper amount at the desired point or points along the track ballast cross-section,the discharge of the ballast being capable of being stopped, retarded, or adjusted as desired, and the balmeans for forming the ballast line at the outer being sides of the car and the lower ends of the 7 known type ed e of the berm of the ballast cross-section. he invention is capable of receiving a variety of mechanical expressions and it will therefore be understood that the embodiment shown on the accompanyin drawings is for purposes of illustration on y, and that said drawings are not to be considered as defining the limits of the invention, reference being had to the appended claims for this purpose.

Referring to the drawings- Fig. 1 is a side elevation of a portion of a ballast carrier provided with a structure em- .bodying the present invention;

2 is a transverse sectional view of a having attached thereto one form the latter being Fig. hopper car of the present invention, shown in side elevation;

onl of the latter being shown; and

E ig. 5 is a fragmentary plan view partly in section, illustrating one manner in which the dresser means may be operatively connected to the ballast carrier.

The structure constituting the subject matter of the present invention is particularly adapted for use in combination with a wellof railway car, but it is to be expressly understood that the invention is not limited to such use.

Referring more particularly to Figs. 1 and 2, a railway ho per car 6, provided with a suitable hopper and hopper door 8, has associated therewith ballast spreading means which, in the present instance, comprises a ballast spreader and a pair of ballast dressers.

The ballast 5 reader comprises a substantially reotangu ar pan structure 9 provided with side walls 10 and with detachable end walls 11. The pan 9 may be operatively connected to the hopper car by means of suitable hook-shaped bars 12 and chains 13, the bars adapted to engage the top edges of the chains being secured to the upper corners of the end walls 11 in any suitable manner. The

pan-shaped spreader is thus removably se- P cured immediately below the hop er 7 in a 'tion to receive ballast from t e hopper when the door 8 is open, said pan extending transversely of the car. Means including a lever 14 are preferably connected to the bar 12 and chains 13 for readily adjustin the height of the ballast spreader above the ead of the rails 15. The bottom 16 of the pan structure 32 is provided with one or more longitu ina ly extending openings 17, and with one or more sliding doors 18 for controlling the flow of ballast throu h said 0 enin or o enin s said slidin oor or doors being suitably actuated, as by means of levers 19. Each end wall of the spreader is provided with a sliding door 20 for controlling the discharge of ballast outwardly over the end of the pan 9, said door beingpreferably controlled by means of a lever 21 having a link 22 which is pivoted to the door 20.

As the details of construction of the ballast spreader or distributor per se constitute no part of the invention herein claimed, it is only necessary to point out herein that the required cribs may discharge onto the ballast crosssection through the opening or o enings 17, and that doors 20 control the discharge of ballast from the ends ofsaid spreader.

. Means are provided at the opposite ends of the ballast spreader 9 for depositing ballast on the track ballast cross-section in the required amount, beyond the opposite ends of the crossties, said means being so constructed that the portions of the ballast cross-section beyond the outer ends of the ties are pro erly shaped substantially simultaneously wit the discharge of the ballast. For this purpose there is provided a pair of

dressers

23 and 24 respectively, which are operatively connected to the ballast carrier and spreader for receiving ballast therefrom.

wall 29 having an openin 30 therein. End

walls

25 and 26 may be substantially parallel and inner portions 27 n and 28 of the two side walls are also substantially parallel,'but the outer portions of said. side walls are pref amount of ballast for the crosstiev erably convergent outwardly. The outer end wall26 is therefore of less length than the inner wall 25. The end wall 25 is preferably inclined with respect to the vertical, and is provided with a centrally disposed opening 31 which forms a. continuation of opening 30, thereby enabling ballast to be distributed intermediate the ends of the crossties and the inner end of bottom wall 29. The lower edge of each of the

side walls

27 and 28 is preferably inclined from the horizontal, the inner end of each edge being higher than the outer end thereof, and the upper edgeof each outer ortion of said side Wall is substantially parallel to the lower inclined edge thereof.

The bottom wall 29 is preferably constituted by two

plates

32 and 33 which are substantially triangular in shape, the inner end of each plate being flanged upwardly as at 32, 33", respectively, and said flanges being,

secured adjacent the lower edge of the inner end wall 25, as by means of rivets 34. The outer edges of

plates

32, 33 are flanged u wardly and engage the lower portions of t e outer faces of'the side walls 27 and' 28 respectivel rivets 35 being preferably employed fbr securing the. parts. The outer ends of

side walls

27 and 28 are flanged inwardly and are secured to the opposite edges of the outer face of end wall 26, as by means of rivets 36.'

In the form ofthe invention shown, the dresser is adapted to be operatively connected to the ballastspreader 9 adjacent the end thereof, whereby ballast flowing past door 20 is discharged by gravity into said dresser. Since it is desirable to vary the angle of the ballast shoulder, and since this angle is controlled by the angular position of the bottom of the shoulder dresser, means are provided for adjustably associating the dresser with the ballast carrier. For this purpose a pair of hanger plates '37, 38 are secured adjacent the upper ends of each fof the

portions

27 and 28 of the side walls of the dresser 23, as by means of rivets 39, the upper portions of said hanger irons being bent inwardly into engagement with each other immediately above the u per edges of the dresser side walls. Secure to the upper ends of the hanger irons, as by means of rivets 40, is a pair of alined pivot pins 41,42. Each of the outer pivot pins 41 is preferably of greater length than the inner pivot pins 42 for a purpose to be described hereafter. The side walls 10 of the spreader 9 are provided with a plurality of openings 43 for receiving the

pins

41, 42. As shown, three openings 43 are provided adjacent the end of each wall 10 in order that the height of the inner end of the dresser,'relative to the ballast crosssection, may be adjusted.

For adjusting the'height of the outer end of the dresser with respect to the ballast cross section, the outer end wall 26 is preferably provided with an eye-bolt 44 to which may e connected a flexible member, such as a chain 45 provided on its upper end with a book 46 adapted to engage a link of one of the supporting chains 13, any change in the adjustment of chain 45 serving to swing dresser 23 about pivot pins 41, 42, and hence changing the angular position of said dresser.

It is desirable to provide means whereby permanent damage will not result to the dresser in the event that the latter strikes an obstacle. In the form shown, the dresser is provided on each of the lateral side walls thereof with a pair of eye-bolts 47. Secured to that pair of eye-bolts which extends in the direction that the dresser is to be moved along the track, are chains 48 which lead forward from said eye-bolts in the direction of travel latter at any suitable point above the points of.- attachment of the chains to the dresser, the grab irons of the car being well suited for the purpose. These chains, which primarily transmit the force required for mov ing the dresser along the track, are each provided with one or more comparatively weak links so that, in the event the dresser strikes an obstacle, such as the end of an unusually long cross-tie, the chains will break and the

pins

41 and 42 will readily slide from openings 43, thereby permitting the dresser to fall tothe ballast cross-section without danger of permanent injury to the dresser structure.

In forming a track ballast shoulder, it is desirable to provide a ballast line to limit the outward fiow of the ballast and thus sharply define the lower edge'of the shoulder. this purpose the dresser may be provided at its outer end with a ballast line cutter 49 formed as a slfarpened blade having rounded of the ballast carrier, and are secured to the For ends, the blade being preferably fashioned intermediate its ends with an upwardly ex-' tending portion 49* which may be secured, as by means of rivets, to the lower outer face of end wall 26. Adjacent the cutter 49, plows 50, 51 are adjustably secured, as by means of bolts 52, to the outer faces of the

side walls

28 and 27, respectively, of the dresser k 23. Each plow is provided with a laterally projecting

flange

50, 51" for throwing the upturned earth outwardly. When the dresser is moved to the left, as shown in Figs. 1 and 3, the right hand, or rear, plow 50 is adjusted so that its share is substantially flush with the bottom of the dresser, while the forward plow 51 is adjusted so that its share rojects below the bottom of the dresser a istance substantially equal to that of the lower edge of the cutter. The cutter 49 is preferably provided with a safety runner 53 for guiding the dresser over small obstacles in the path of travel of the outer end of the dresser, said runner being constituted by an angle iron having its opposite ends curved upwardly and having its vertically disposed portion fixedly secured to the outer face of the cutter 49.

, Means are preferably provided on the dresser for supporting the operator who controls the device, the weight of the operator assisting in the proper formation of the ballast cross-section and the ballast line. For this purpose a platform 54 is fizgedly secured in any suitable manner to the outer end of the dresser and if desired the upper surface of this platform may be suitably corrugated to provide a sure footing.

When it is desired to form a ballast shoulfrom the inside of one of the side wa11s 10 of r wallof the spreader .able portion, or

the spreader and pivot in 42 is inserted in one of the openings 43 in theopposite side from the outside of the latter. Adjusting chain 45 is then engaged witha suitable link of one of the chains 13, whereby the dresser is supported in the desiredangular position. Drag chains 48 are then led forward and are secured to a suitrtions, of the ballast carrier structure. he operator then mounts the platform 54 and actuates lever 21 to raise door 20, thereby permitting ballast, which has been discharged from the hopper into the spreader 9, to fall by gravity into the dresser. As the carrier and dresser are moved along over the ballast cross-section, the plow and cutter form the ballast line, the upturned earth being thrown outwardly clear of the shoulder by means of the laterally extending portion 51 of the plow. It will be noted that the plows are secured to converging side walls and due to this convergence the laterally projecting ortion 51 of each plow assumes an angu ar position relative tothe direction of movement of the cutter and plow, thus insuring that the earth will be turned outwardly.

As the dresser moves along the ballast cross-section the ballast falls through the

opening

30, 31 and the shoulder is formed automatically, as an amount of ballast sufficient to completely fill the space between the sub-grade and the lower surface of the dresser will discharge by gravity from said dresser. Flow of'the ballast outwardly beond the desired distance is prevented by the llast line. If the dresser passes over a portion of the ballast section where the shoulder is properly formed, no ballast will escape through

opening

30, 31, but when the dresser is moved over a depression or pocket, sufficient ballast will 'flow from the dresser to fill said pocket and bring the upper surface of the ballast to the desired configuration. The device is thus entirely automatic in action, it only being necessary forthe op- 'erator to raise door 20 to permit the ballast to fall by gravity into the dresser, the latter being maintained substantially full of ballast at all times during the operation thereof.

As shown more clearly in Figs. 2 and 4,

the structure of the present invention indresser 24 for use in properly shaping the ballast deposited between double tracks. The ditch dresser is guite similar in construction to the shoulder resser and comprises

end walls

25, 26, a bottom constituted by

plates

32 and 33, a platform 54, and pivots 41, 42. The lower edges of the

side walls

55 and 56 of the ditch dresser, however, extend outwardly at a lesser angle relative to the inner wall 25 than in cludes a center ditch V the case of the shoulder dresser, although it will be understood that this an varied as desired. Moreover, p

le may be atform 54 may be slightly inclined, since, stances, it is desirable to adjust the angular position of the ditch dresser 24, as b means of a suitable supporting chain 57 so thatsaid center ditch will slope downwardly away from the adjacent edge of the cross-ties initeadgof extending horizontally as shown in As the wall 29 of the shoulder dresser 23 inclines downwardly away from the car its portions on opposite sides of the opening 30 trim or dress posited beyond the ends of the cross-ties, thus shaping the shoulder of the ballast cross-sec tion- The portions of the bottom plate 29, at the sides of the discharge opening in the center ditch dresser 24, similarly serve to dress the ballast deposited at the 0p osite side of the track so as to impart to it'tli shouldered form. The

dressers

23 and 24 are preferably constructed so that the ballast may be delivered therefrom substantially centrally instead of at the side, such a construction being especially advantageous in that, no matter in which direction the dressers move alon the track, it enables one or the other of t e

bottom plate portions

32 and 33 at the sides of the discharge openings 30 to trim and shape the mass of ballast being deposited. Usually the slope of the center ditch is such that when the dresser 24 is adjusted for forming a ditch' of this character, the platform 54 is substantially horizontal. The ditch dresser is provided with chains 48 similar to those employed in connection with the shoulder dresser and they are likewise secured to the car above the oints of attachment of the chains to the resser.

in certain in-.

Secured the ballast as the latter is dee desired to the bottom faces of the platesf32 and 33 to readily pass over the obstruction. In the.

event an obstruction projects an-unusual distance above the desired level of the ballast the dresser may be caused to rotate to an extent such that an inordinate amount of ballast will be discharged. However, due to the fact that an upward swinging movement of the dresser decreases, in effect, the distance between the opposite ends of the chains, the hinge pins 41 and 42 and chains 48 are so proportioned and arranged that when the dresser swings upwardl an unusual. amount the hinge pins will sli e from openings 43 thus permitting the dresser to fall to the roadbed thereby preventing the undesired discharge of ballast. It is obvious that should the shoulder dresser, for any reason, swing upwardly to a similar undesired extent, it will become detached from the an obstacle is encountered which the ditch dresser cannot pass over, the chains, being provided with one or more comparatively weak links, will break and permit disenga ement of the dresser from the spreader in t e manner heretofore described.

Ballast may be discharged into the crosstie cribs by actuating levers 19 and sliding doors 18, said levers being readily actuated simultaneously with lever 21 and door 20 so that ballast is discharged in the proper amount simultaneously onto all portions of the track ballast cross-section. It will also be apparent that the shoulder and ditch dressers may be used separately or simultaneously.

There is thus provided means adapted to be associated with a railway car, for receiving ballast, and depositing it selectively onto the shoulder, the center ditch, or the crosstie cribs in the proper amount, the ballast so I deposited being shaped 'to form'the shoulder and the center ditch. The necessity for manually handling the ballast is avoided. The ballast spreading and dressing means may be. readily attached to, and detached from the car, and no structural change in the latter is required .for this nurnose. The ballast line is formed substantially simultaneously with the discharge of the ballast onto the cross-section. Means are provided for operatively connecting the dressers to the car in such a manner that the dresser structures are not permanently injured when an obstacle is encountered.
