ROAD-SURFACING MECHANISM. s*

Application med August 7. 192,2. Serial No. 580,!i80.

which the following is a specification.

My invention relates to a road-surfacing and grading mechanism, and more particularly7 to a mechanism for distributing 'cleaning up rendering uniform and finishing the material used as ballast either on the road bed of a railroad or of a highway, and also for grading the track of a railroad.

fMy, invention Wil-l be particularly described as related to a railroad but it is understood that its application is not limited to this particular field of use. Heretofore in railroad construction the practice has beento run the gravel train upon the uneven newly laid track, and dump the Xgravel or crushed rock constituting the ballast material between the rails and then employ a large number of workmen to manually distribute the ballast material and properly surface the road-bed. Previous to distributing the material the rails must be elevated to track grade; and this lifting is ordinarily accomplished by means of jacks. @bviou'sly the distributing of the material and elevating of the track manually is costly and very slow. i

lt is in general the purpose of myinv'en-V tion to perform this work by a machine, to do the same Vexpeditiously and to cheapen the cost. A primary object of my invention is to provide a road surfacing mechanism which will level ofi', distribute, and position the surfacing material in the form of roadbed desired. A further primary object of my invention is to provide such a road surfacing mechanism which Will carry a supply of ballasting material which may be precipitated in front of the surfacing mechanism in places where there may not be a suiiicient supply of such material. A further primary object of my invention is to provide such a surfacing mechanism that the parts of the machine which actually come in contact with the road-bed may be elevated so thatv proper clearance may be had of the road-bed While transporting the surfacing mechanism to and from the sections of the road-bed which are to be operated upon by the machine. A further primary object of my invention is to provide a mechanism which may be employed in lifting the track, inlorder that the same may be raised to predetermined track level or grade, and in order that said track may be raised in cases of repair Work, Y for the quick removal of vvorn out ties and for the quick replacement ofthe same.

Theabove mentioned general objects of my invention together with others inherent in the same are attained by the mechanism illustrated in the following drawings, the same being merely preferred exemplary forms of embodiment of my invention thru,4

Fig. 9 is a View in side elevation of a modiiied form of my mechanism provided With caterpillar traction members for operation on highways or in the absence of a track.

A. supporting vehicle or car (10) havin fixed frame (11) mounted on railroa wheels (12) is provided with a secondary frame (13) pivotally mounted at (14k). Upon this secondary frame (13) are disposed in large measure the material distrib-- p ting parts of my mechanism. rfhis secondary frame is preferably provided with an elevating mechanism for the same. rllhis Vmechanism as illustrated consists of a screw (15) provided with a gear (16) which in turn engages a pinion (17). This pinion is in turn operated by a crank (18), or if desired the said elevating means may be connected with the power means of the device.

On the front part of this secondary frame (13) is rotatively mounted a rotary digger (19) the function of which is to loosen the ballast material with which it may come in contact. rihis digger is mounted on a -vertically adjustable shafting (20) which is journaled in a housing (21) to which is secured rod (22). About this rod is a compression spring (23) disposed to hold said digger in its lowermost position, but which will permit said digger and its journal to rise upon meeting unduly great resistance so that breaking of the teeth may be prevented.

Back of thesaid digger is disposed a scraper (24) pivotallyl mounted at (25) and supported on its forward end by a wheel (26) idly mounted on shaft (27) having a link (28) which inclines backwardly, which shaft is journaled to the secondary frame (13). A carrier (29) preferably in the form of an endless belt is mounted immediately back of the said scraper (24). This belt is mounted on pulley (30) and driving pulley (31).l Back of the said carrier belt is mounted surfacing rollers (32) and (33) pivotally mounted at (34) by means of arm (35) said arm vbeing pivotally attached to a rod (36) which is preferably provided with a spring (37) which exerts a downward force upon its respective rollers.

On the rearmost part of the secondary frame is preferably disposed a rotary brush (38), the function of which is to provide a neat finish to the work and sweep all ballast material olf the top of the ties. This brush is adjustably mounted on rack (39) which rack engages pinion (40) by means of which the said rotary brush may be elevated so as to clear the track if desired.

A transverse conveying endless belt (41) receives the material deposited thereon by the endless belt (29). This transverse carrier will deposit the material into a spout member (42) which will discharge the eX- cess of ballast material to one side of the road-bed or, if preferred, conveyors could be provided to return said excess material to other cars in the rear. Moreover, this spout member is provided with a hole (43) covered by a slide (44) which will permit the material to fall upon the longitudinal carrier (45) which in turn is disposed to deposit the material in a hoppenshape bin (46) having a sloping floor (47) which causes the said material to move toward the middle of the car. This bin is provided with a sliding member (48) which may be withdrawn and permit the material to fall upon such portions of the road-bed as may have been inadequately supplied with the ballast material. A sloping screen (49) is preferably provided paralleling and spaced above the sloping Hoor (47), which provides for supplying line material in a separate compartaient (50) formed by a partition (51).

A track lifting mechanism is provided on the front end of the car (10), consisting of a stilt member 52 on each side of the car. said members having oppositely disposed leg members (53), which straddle the track rails (54). Inside the stilt member (52) is a block (55) slidably mounted therein. This block '(55)'is also mounted on a threadedshaft (56), which is journaled in the upper' part of the stilt member (52). Thrust collars (57) and ('58) maintainsaid shaft in said stilt so that it does not move up or down longitudinally of said stilt. A bevel gear (59) mounted on the end of shaft (56) imparts rotary movement to said shaft (56) which causes the block (55) to move up or down as desired. To said block is detachwhich is pivotally mounted by trunnion 66 in bracket 67.

An elevating mechanism for the stilt memberI 52 is provided by means of a pinion 68 engaging a rack 69. The teeth of this rack 69 are in a plane inside of the plane of the edges 70 of the stiltmember, in order that the edges may serve as guide means to the stilt member, and thereby avoid all contact by the teeth with the guide block 65. 'l

The modified form of a device embodying my invention shown in Fig. 9 is provided with the caterpillar 71 which adapts the same to travel independent of any track.

The modevof operation of a device embodying my invention is as follows:

If the track is not at grade the stilt 52 is lowered in position With the leg members 53 disposed astride the track rails 54 as illustrated in Fig. 7. The lowering of the stilt member is accomplished by actuating theV pinion 68, which engages the rack 69. Thereupon a suitable means may be employed to connect the said track'to the block 55. As herein shown. a chain 60 is employed to releasably secure said track to said block. Thereupon the actuating means connected with the bevel ear 59 is set in motion, which causes the said gear to revolve and this in turn causes the threaded shaft 56 to screw into the block 55. Since the said shaft is held by means of thrust-collars in a fixed position, the block 55 is caused to move upwardlv as respects the said shaft, thereby lifting the track tothe desired grade line, and of course lifting'with it the end of the car to which it is attached. Y Let it be noted that in accomplishing this there is no strain put upon the springs of the car itself. Also be it noted that the elevating stress is applied directly above the rail and as close thereto as can be, and pery init-ting a clearance for elevating the track. lt will be understood that the stilt members on each side of the track are thus caused to lift their respective rails.

After thus elevating the rails to grade,

recetas material is disposed beneath the ties so that, the said rails are maintained at said grade. rihis may be accomplished by pulling.;r out slide48 of the bin on the' front end of the car, or by blocking if desired. Having thus secured the rail in elevated position, the stilt member is elevated to clear the ties, and any ballast material that may be between fthe rails. 'lhen t-he surfacing machine is caused to advance. 1While advancingthe digger member 19 is caused to revolve and loosen ballast'material which has been deposited between the rails. After the same is loosened the material will come in contact withy the scraper 24 on which it will ascend either by being pushed by the accumulation of material ahead of the scraper or if preferred the wheel 72 maybe provided with paddle like projections 73 which will assist the material in ascending the scraper 24 from Whichit will fall upon the moving belt 29. From the moving belt 29 the material is dropped upon transverse carrier 41 which carries the surplus material to one side of the track, or if preferred other carriers '(not shown) may be employed to load this'on cars in the rear. Or again, said surface material may be caused to fall through vthe opening 43 upon the longitudinal carrier 45, from which the material may be caused to fall into a bin 4G. ln this wise ballastfmaterial may be available to4 be deposited between the tracks at any point where there may be an insufficiency of material. Imme.

diately behind the moving belt 29 are the surfacing rollers 32 and 33 which operate to smooth the ballast that is left between the ties. These rollers are mounted so as to be yinclined and thereby tend to form the ballast with sloping sides between the rails so that the ballast is higher in the middle than on each side. Immediately behind said rollers is preferably provided a rotary sweeper 38 which serves to sweep clean the top of the ties.

In this wise the machine is advanced section by section, firstelevating thetrack to grade and then doing the surfacing' operation.

0n a finished road, where it is necessary to remove one or more ties, the applicability of the surfacing mechanism herein described 1s manlfest. The rails may be lifted and i thus ties removed that need to be replaced.

If any new ballast material is desired it is readily available in the bin 46, wherein is provided either course or fine material.

lVhen the work is completed it is only necessary to elevate the secondary frame 13 by means of the pinion 17 to remove all of theoperating parts connected thereto, above the ground sufliciently to clear all ordinary obstructions between the rails. The rotary brush 38 is elevated by means of a separate rack 39 as the angle through which it would be caused to revolve by elevating the secforms, dimensions, and arrangement of the parts of my invention without departing from the principle thereof, the above setting forth only preferred forms ofA embodiment.Y
