To all whom t wacom.'

Be it known that l, JOHN F Rona, a citizen of the United States, residing at? Cleveland Heights,l inI the county of Cuyahoga and State of Ohio, have invented certam new and useful Improvements in Finishing Machines, of whichthe. .following is a speciiication.

In the art o f making'concrete pavements and roadsit has been proposed to utilize a finishing machine comprising a roller adapted to be moved back. and forth over the plastic concrete so as to act thereon by pressure, or ironing, so to speak, to finishthe road surface. This roller, arranged transversely of the road-bed is of considerable.

Weight, and, therefore, is enabled to have the ironing eiiect desired in order to strikeod, and Work the concrete in such a manner as to form the desired smooth surface.

The present invention com rises the com-v bination with la roller suitab y supported to operate on the plastic aggregates of a concrete road, in the making thereof, the said roller being arranged transversely ofthe road,`of a second roller disposed longitudinally, or lapproximately longitudinally of the road, and movable back and forth `crosswise of the road-bed, so as to supplement the action of the first named roller inperforming the finishing operation. The transverse and longitudinal rollers are complemental in tlieiiiunctions, in that oneacts -primarily to iron the plastic road a gregates in one direction whilst the other irons or works the aggregates in another direction,

'namely transversely of the road-bed,- the latter roller furthermore acting to carry of surplus water that may rise to the surface of the aggregate in the finishing operation.

Subsidiary to Lthe foregoing, I utilize means whereby, if desired, the roller which operates transversely of the road may be caused to 'shift into slightly angular posi-v tions, as distinguished from a true longitudinal position in relation to the roadfbed,I so that said roller is given asort of'diagonal disposition'enablin it to travel slightly forwards as the machine which carries the sev' eral rollers moves forwards in itsprogressive finishing action. Since. this second acting roller reclprocates 1n its movement /across the road-bed, 'in its practical operation, it is evident that its angularity of l on the line 8 8 of Fig. 71

when its direction of reciprocation is reversed, and the invention comprehends means enabling such action.,

My invention embodies other phases of construction and combination of parte which will be more fully understood upon reference to the following description in conjunc tion with the' accompanying drawings in which;

Figure 1 is a top plan view illustrating a simple embodiment of my combined transverse and longitudinal roller type finishing machine. l y

lReferring to the drawings, and especially Figures 1 to 5 inclusive, A. denotes a wheeied l trucker support in which is mounted in suitable bearings a main finishing roller 1. The wheels of the support A. are denoted 2, and are adapted to operate upon what are ordinarily knownas road rails or forms disposition just referred to must. bev reversed tracted toward its middle portionv *from op-l H0 posite ends, or in other words, is provided A with a contour which corresponds with the crown of the road. This roller 1 may be mounted for vertical adjustment, if desired, this not being material to the present invention.- I utilize any suitable power plant, such as a motor B,Yon cross pieces 3 of the support A, for driving the roller 1. For the above purpose I utilizes. dri-ve shaft 4.lead ing from the motor B to one end of the support or carrier A, said shaft having a bevel gear 5 meshing with the corresponding gear 6 on a shaft The shaft 7 has a gear 8 with which either one of two clutch gears 9 and 10 is adapted to engage. The gears 9 and 10 are carried byl a suitable shaft 11 to which they are keyed, and are movable by a yoke 12 to alternately engage with the gear lau 8. In this wav the motion of the shaft 7' isadaptedto be Atransmitted to the shaft 11 to `operate the latter in reverse directions. The shaft 11 has a gear 13 meshing with'a bevel gear 14 on a cable actuating shaft 15. The shaft 15 carries a'drum 16 about which win'ds and unwinds a cable 17. The cable 17 passes over a pulley 18 on a shaft. 19 supported at one side of the carrier or wheeled support A, the shaft 15 and the drum 16 being located 'at'the opposite side.. Itwill'be evident that by connecting thev cable 17 with the frame of a trolley 20, and controlling the clutch gears 9 and 10 to reverse the 'driving of the cable 17, a reciprocating mo- -tion may be imparted 'to said trolley 20. The trolley 2()` is mounted in curved tracks 21 which consist of channels, shown best in Figure 5, there being attached to the. under side of -one of said channels, an operating rack 22. The tracks 21 .are supported upon..

a pair of arms 23, which really constitute a 'sort of auxiliary support extending to the rear of the main wheeled su port or carrier A. The arms 23 are pivotecrl at their front ends at 24 to verticall adustable members 25 adapted to be raised, an lowered slightly by means of turning collars 26 mounted upon Athreaded portions of said members 25 and having a bearing against the u per surfaces of the sides of the frame W ich constitutcsthe support A. Any suitable means may be used to adjust the pivotal connect1ons24 between the arms 2.3 and the truck or carrier A. rlhe rear ends of the armsmay '.'be equipped with wheels 26, or not, as may be found most desirable, and rendered susceptible of 'vertical adjustment by means of adjusting screwsV 27, adapted to raise and lower the wheels 26 in their journals. The trolley 2O is equipped with small rollers which operate in the channels or the tracks -of channel beams 21, and this trolley 20 supportsl what .may be called the transversely .moving roller 28 of the machine. The roller l 28 is suitably journalled in a U shaped frame 29, carried by the frame of the trolley 20.

Mounted inthe frame of the trolley 2t) is a connected by bevel gear 33 with a bevel gear 34 on the upper end of a short vertical shaft 35 which passes thru the central portions of the trolley frameandthe roller supporting frame 29. At its lower end-4 the shaft 35 carries a bevel gear 36 meshing with a corresponding gear 37 mounted on a short shaft 38 thatleads from the center of the frame 29 to one end thereof and is connected by a train of gears 39 and a shaft 40 with the rollei` shaft 41 that carries lthe roller 28.

It is obvious, therefore, that as the trolley 20 is pulled in one direction across the niachine and ac rossthe roadbed, the roller 28 will be driven by rotation in one direction, and when the movement of the trolley is reversed, the roller 28 will be driven in an opposite direction. rIhe elevation. of the roller 28 may be controlled by thev parts 27 and 26 as before described. The movement of the trolley 20 is automatically reversed as the roller 28 approaches one side of the machine, by contact of one end of the trolley 20 with a clutch reversing lever .42 associated with the shifting yoke 12 previously mentioned, and when the trolley has been reversed, and moves so that it has reached the opposite side of the machine, lthe said trolley engages another reversing lever 43 which is connected by a rod 44 with the yoke 12 by which the ears 9 and 10 are shifted. Any suitable mec ianism may be utilized for effecting the desired movement in opposite directions, automatically controlled, of thetrolley `20 and its roller28. It is conteur# plated that the roller 28 sli-all move transversely of the machine` until it reaches a point'very slightly beyond the road forms or rails upon which the wheels 2 and'26 of the machine move. This insures a -proper surfacing action by the roller 28, anactlon upon the wholeI surface of the concrete aggregates, andthe pushing oil of surplus Water if desired; It is notable that the rails 21 for the trolley 2O are curved crosswise of 1 the machine to correspond with ,the crown of the road-bed, so that in ellect the roller `28 moves in a curved path conforming with It isdnotable alsothat the roller 28 is preferably tapered at its opposite ends so as to prevent endwise pushing ol the surface aggregates of the plastic concrete being operis driven either in the same direction as the I forward movement., or in an opposite direction,as ma `be found most desirable in practice. Att e same time, the roller 28 moves transversely of the machine, iny rear of the roller 1, and during its transverse movement the roller 28 is positively actuated while it bears with pressure upon the surface aggregates. 'l`he roller 1 irons out the surface aggregates, so to speak, in one direction, and

the roller 28 acts likewise in another direction.

I contemplate to use certain means'best illustrated in Figs. 7 to 11 inclusive, to shift the frame 29, to position the roller 28 with a slight degree of angularity, or facing slightly forwards in the direction of its transverse movement, so that in effect it is not presented exactly lengthwise to the progressing movement of the entire machine.

This adjustment Vof the roller 28 will have a tendency to avoid any possibility of edgewise pushing or disturbance of the surface aggregates, and will facilitate the free move-4 nent of the roller over the aggregates as the machine progresses. With the above in view, instead of having the frame 29 substantially rigidwith the frame ofthe trolley, as s hownfin Fig. 5, I utilize the shaft 35 as a pivot means connecting the trolley frame 20 and the roller supporting frame 29 at their central portions. As seen best in Fig. 9, the gear 34 has mounted thereon a friction arm 46 which engages in the fork 47'of a trip arm 48 carried by the stub shaft 49 mounted in the `trame 20. At its lower end the shalt 49 carries a trip member 50 engaging between lugs 51 of a reversing slide 52 mounted and guided on the .under side of the frame 20. 0n the roller frame 29 is a sliding latch 53 normally spring actuated y to become disengaged at its inner end from clutch lugs 54 on 'the gear36. At its outer endthe latch 53 has an upwardly extending projection or lug 55 passing thru-a slot in the frame 29 and engaging 1n a cam slot 52 of4 the reversing slide 52. The cam slot 52 has cams at its opposite ends and theact-ion of the mechanism described is substantially as follows:

When the trolley 20 reaches one end of its traverse on the truck or support A, the movement of the trolley is :reversed and this results in a reversalot the movement ot' the shaft 30. Such movement ot the shaft 30 is transmitted tothe gear 34 and its fri`ction arm 46. Such action causes a rocking of theshatt 49 and this thereby shifts the reversing slide 52 camming'the latch 53 into engagement with the gear clutch lugs 54 and against' the tension ol the spring 53a surrounding said latch. The latch. 53 is thus momentarily clutched and the gear 36 which is of course turning in the now reversev direction to its previous movement and since the latch 53 is carried by their-ame 29, the latter-is compelled to 'turn with the gear 36 a slight distance until-the lug 55 of the latch reaches the other end olf the cam slot .52a of thereversing. slide 52, see Fig. 10, where' upon the lug enters the cam` slot extension at the opposite end ot' the slide 52, and the latch becomes disengaged from the gear 36.; rThe Aframe- 29 will thus have been' shiftingl soy and seen in Fig. 10. The action oli the slide 52 is automatic both in engaging the latch 53 with 'the gear 36, and

disengaging it, and

is controlled by the operation ot reversa-lot -rnovementot the shalt 30 incident tothe Vreversal of direction out drive oit the trolley 20 thru the operating mechanism including- 'the gears 9 and 10, cable 17, and vintermediate connections. The operation ot the parts shown in Figs. 9 and 10 takes place lurthermore at both extremes-ot movement of the' trolley 20 and its roller 28. x

For the purposes of this description, 4the roller 1 may be said to be a transverse roller in the sense that it is mounted transversely of the machine; roller 28 is a longitudinal roller generally speaking, and moves transversely of the machine. Furthermore, the rollers 1 and 28 are disposed at angles to one another, a right angle as shown in Figures 1 `to 4 inclusive, and at slightly difiere-ut angles when adjusted in the operation of the parts set forth in Figures 7 to' 11 inclusive.
