ROAD-WGRKING MACHINE.

Specification of Letters Patent.

Patented Dec. 7, race.

Application filed. November 27, 1908. serial No. 464,776.

Be it known that it, MICHAEL A. PoPKEss, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Road-Working Machines, of which the following is a specification." A

This invention relates to road-working machines, and more especially to a machine capable of use as a traveling earth-surfacing-material heater, or traveling. mixer of such material with a binder inrliquid condition and preferably having tough, tenacious, sound-deadening and water-proof properties.

- 'With these objects in viewthe invention consists in certain novel and peculiar features of construction and organization as hereinafter described andclaimed; and in order that it maybe fully understood ref-. erence is to be had to the accompanying drawings, in which; L

Figure 1 is a side elevation of a machine embodying my invention, arranged for raising loosened connhinuted or pulverized earth-surfacing material and for heating the same while elevated or for mixing a binder with the elevated material. Fig. 2 is a top plan view of the same. Fig. 3 is a section on the line III-III'of Fig. 2. Fig. 4 is a rear view of the machine. Fig. 5 is an enlarged. vertical section on the dotted line V of Fig. 2. 3

I Referring now to the drawings, 1 indicates a pair of parallel channel bars arranged horizontally and connected by

crossbars

2, 3 and 4, and also by a cross-bar 5 resting upon a bolster 6 equipped with a king-bolt 7 forming the pivot for bar 6, and

engaged at its upper end by a retaining not 8, the bolster forming a journal for shaft 9 equipped with carrying wheelslO.

A pair of horizontal bars consists of par;- allel portions 11 arranged vertically under the rear portions of bars 1, the parallel front portions 12 arranged I a greater distance apart than portions 11 and bent portions 13 connecting the front ends of portions 11 with the rear ends of portions 12 and provided at the rear ends of the latter with arches 14. The portions 12 of the horizontal bars are spaced more widely apart than portions 11 to accommodate the plow or shovel hereinafter referred to which projects laterally beyond portioin l1 and wheels 18 hereinafter more particularly referred to, in order that said wheels may run on the bottom of the furrow or channel made in the ground by said plow or shovel.

15 indicates upright bars secured at their upper ends to bars 1 and at their lower ends to portions 12 of the lower bars, the portions 11 of the lower bars being connected to the upper bars by parallel upri ht bars 16.

17 indicates blocks carried by bars 16 and forming bearings for short shafts 17 on which are mounted the rear carrying-wheels 18 arranged by preference in line with the front wheels at the corresponding sides of the rigid frame described, the rear wheels and it is desired in this connection, to. state that any other type of ground-engaging supports may be employed in lieu of the wheels referred to, and that the machine is adapted to be propelled by horse-power or any other readily ride over obstructions in its path.

20 indicates a fire-brick or equivalent combustion or heat-concentrating chamber superposed upon plate 19 and open at its rear end, its front end being closed by a wall 22 provided with one or more openings 23 through which rearwardly project one or more valve-controlled burners 24 for use in connection with fuel in fluid condition, the holder for the fuelbeing omitted as forming no essential part of the invention, as it may be carried by the wheeled frame or extraneously thereof.

25 indicates a hollow cylinder arranged longitudinally of the frame and provided with a pair of circumferential tracks 26 engaged peripherally by flanged rollers 27 journaled in brackets 28 carried by portions 11 of the lower longitudinal bars of the frame, and said rollers being disposed below the axis of the cylinder and at opposite sides of the same, similar rollers 29 engaging the circular tracks vertically above the axis of the cylinder and being mounted on a longitudinal shaft 30 journaled in

bearings

31 and 32 carried by

cross-bars

3 and 4 respectively. The flanges of rollers 27 and 29 engage the adjacent edges of the circular tracks and thus guard against endwise movedepending to a lower plane than the front wheels for a purpose hereinafter explained,

ment of the cylinder when it is revolved, as

hereinafter explained, it being noticed in this connection that additional rollers 33 may be employed to assist in supporting the cyllnder, two of which rollers are mounted in brackets 34 similar to brackets 28, and the third on shaft 30 as'shown most clearly in Fig. 2. The cylinder is also provided with a circular 'rack 35 engagedby drivepinion 36' secured rigidly'on shaft 30. The shaft isalso provided with a-bevel-gear 37 meshing with a similar gear38 on a transverse shaft 39 journaled near its opposite ends in a bearing 40 carried by cross-bar 4 and a bearing 41 carried by one of the bars 1. Rigidly secured on shaft 39 is a sprocketwheel "42 connected by a chain 43 with a sprocket-wheel 44 rotatable with one of the s afts 17, so that as the machine travels the last-named traction-wheel 18 imparts rotatable movement through the gearing described, to the cylinder 25, and in order that the cylinder may elevate and drop loose earth-surfacing'material in such movement, I provide the cylinder internally with cleats 45 arranged spirally for purposes of imparting rearwardly movement to such material and eventually dropping it upon the roadway.

46 indicates a plow or shovel pitched downwardly and forwardly at such an angle that its front end occupies the horizontal plane of the lower side of wheels 18, its rear end projecting into the front end of the cylinder a slight distance. The front end of the plow or shovel is slightly wider by preference than the distance between the outer sides of wheels 18 and at its converging sides is provided with flanges. or moldboards 47 which curve upwardly and inwardly for the purpose of concentrating the material scooped up and discharged into the cylinder, an inturned flange 48 being provided to guard against any of such material escaping from the front end of the cylinder. The plow or shovel is provided with a rod 48 pivotally engaging bearings 49 secured to the underside of portions 13 of the lower bars of the frame, and pivotally secured at their lower ends to the plow or shovel forward of its'pivotal point, are stayrods 50 adjustably bolted at their upper ends at 51, to the upper bars 1 of the frame. By proper adjustment of the stay-rods the plow or shovel can be arranged to cut or operate at varying depths or be raised to ino erative position above the ground.

0 prevent the walls of loose earth, produced at opposite sides by the plow or shovel in its assage, from falling inward behind said p ow or shovel, I provide a pair of guards 52 arran ed arallel, in vertical planes between t e low or shovel and wheels'18. Said guar s underlie the arched portions 14 of the lower bars of the frame its front end.

drying and and forward of said portions curve upward at 53, the curved ends having a series of holes '54 through any one of which of each bar, a pivot-bolt 55 carried by the adjacent lower bar of the frame, plvotally extends.

The guards 52 project beyond the rear end of the cylinder and at their rear ends carry a connecting spreader 56 of V-shape in plan view, said spreader being arranged with its lower edge 1n substantially the same horizontal plane as the lower portions of wheels 10. The function of this spreader is to distribute the material as discharged from the cylinder upon the underlying bed of earth so as to fill the furrow produced by the plow or shovel. As a means of securing the spreader and the rear ends of the guards 52 above the surface of the ground, a pair of rods 57 are secured at theirlower ends to the spreader and at their upper ends extend slidingly through the channel bars 1 and are equipped with adjustable collars 58 to rest on said bars.

The earth-surfacing material is first loos-.

ened and comminuted or pulverized to a suitable depth by any suitable implements, rocks of objectionable size being incidentally removed. The machine is then propelled in as straight a course as possible over the prefirst set in operation so as to discharge a flame or flames rearWardly-tlirough the combustion or heat-concentrating chamber, this chamber being preferably of sufficient length to accommodate'a large volume of hot-air and thus facilitate and insure perfect com bustion of the fuel, in order that an exceedingly hot blast may play upon the mass of loosened material gathered up by the plow or shovel and deposited in the cylinder at The said blast in practice, will be sufficient to effect a consumption of practically all organic matter contained "in the material thus elevated. As the material thus heated, falls into the cylinder, the revolution of the latter through the instrumentality of cleats 45 lifts the material and, according to its speed, drops the same or terial so that in such scattered or widely distributed condition it shall be subjected to the heatinginfluence of the hot-air passing continually through the cylinder from front to rear. In the revolution of the cylinder the material is not only scattered to render it more susceptible to the heat but it is fed continually rearward because of the pitch or inclination of the cleats and through the constant advance of the machine, it being obvious that the material while falling from the upper to the lower part of the cylinder has a relative -rearward movement with regardv to the advancing machine. The'material is raised to the desired temperature by the time it attains the rear end pared material, the burner or burners being.

through centrifugal force, scatters such maerases of the cylinder and falls therefrom back upon the underlying bed or roadway so as to refill the furrow or channel produced by the plow or shovel, it being noticed in this connection that the rear wheels 18 travel in said furrow or channel and thereforeupon a substantially solid bed and thus tend to regulate the depth of cut of the plow or shovel. It will also be noticed in this connection that the cleats 52 flanking the rear wheels and the plow or shovel, act to pre vent the walls of loosened material produced by the passage of the plow or shovel, from falling into the furrow or channel in the path of wheels '18. The heated material as it falls from the rear end of the cylinder tends to pile up, and to. spread or distribute of such miXture being eventually. distribthis material and cause it to eventually fill the furrow or channel, the spreader 5b is provided, though it is to be understood that I do not wish to restrict myself to the use of the spreader as it is not an indispensable element.

When it is desired to employ 'themachine in mixing a binder in liquid condition, with the earth-surfacing material, such binder, preferably while hot, will be discharged from a tank not shown) carried on or movable with themaehine, through a suitable jet. pipe 59 onto the earth-surfacing material as the same enters the cylinder, by preference. The n'iaterial thus sprayed with the binder is stirred and thoroughly amalgamated, with such binder, in its passage through the cylinder, the resultant product uted by the spreader in the furrow or channel produced by the plow or shovel, as will be readily understood, it being of course apparent that the burner or burners and the binder-supplying apparatus are not oper-. ated simultaneously. In practice the machine will be first operated to heat the earth surfacing material and then, while the material is bot, will be caused to travel over the same path for the purpose of reelevating the material and mixing with it a binder of the character described. After the surfacing material has been heated and the binder -incorporated in it, it may be harrowed if desired, to effect a more intimate and thorough mixture, and then it is com.- pacted or con'ipressed'by tamping, rolling or in any other suitable manner, so as to constitute a comparatively smooth, even and dense surfacing possessing resilient, sounddeadening and water-proof properties.

From the above description it will be ap-v parent that I have produced a machine for heating. loosened earth-surfacing material which embodies the features of advantage bodiment of the same I reserve the right to rear endof the frame to evenly spread t make such changes in the form, proportion, detail construction and arrangement of,the parts as properly fall within the-appended claims.
