Serial No. 410,056.
My invention relates to paving machines, particularly to machines for laying concrete or the like upon the roadway, and the objects of my invention are: First, to provide a ma'- F chine which receives the mixedl concrete or other paving material from trucks or from 'a concrete mixer, spreads it evenly from side to side of the roadway, then tamps it so as to A increase the wearing qualities, andl then v. smooths off any irregularities; second, to provide a road making orpaving machine which is supported and travels on headers formed along the sides ofthe roadway; third, to'provide a machine of this classwhich may operate continuously although the pavingv material is dumped in periodically; fourth, to provide a novel tampln means in connection withv a road paving mac ine; fifth, to provide a road paving machine in which the cutoff and leveler mechanisms and other members which oscillate transversely to the road maintain atV all times the proper contact with the paving or roadway so as to insure the proper crown; sixth, to provide a machine of this d of paving; seventh,to lprovide a machine of this class ,which requires a minimum amount of skill p and labor to operate; eighth, to provide a machine of this class which insures a uniform roadway; and ninth, to provide on the whole a novelly constructed roadwayor paving machine which is simple of construction proportional to its functions, durable, eicient in its action, and which will not readily deteriorate or get out of order.
' With these and other objects in view-as will appear hereinafter, myinvention consists of certain novel features of construction, combination and arrangement of parts and portions as will be hereinafter described indetail, and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters application, in which:
,Y Figure 1 is a longitudinal, sectional view of my road paving machine, taken substantially through '1-1 of'Fig. 3; Fig. 2 isa transverse sectional view thereof, through 5 2-2 of Fig. 1; Fig. 3 is a plan view thereof,
of reference thereon which form a part of this t with parts and portions broken away and in section to facilitate the illustration; Fig. 4 is a fragmentary, enlarged, transverse, sectional view through H of Fig. 1, with parts and portions removed or in elevation to facilitate the illustration; 'andFig 5 is another enlarged, fragmentary, transverse sectionalview, through 5-5 of Fig. 1.
-Similar characters of reference refer to similar parts and portions throughout the several views of the drawings.
Side members l, cross members 2, 3, 4, 5, 6, 7, 8, 9, 10 and 11, wheels 12, hopper 13, cut-off member 14, hanger rollers 15, guide rollers 16, cylinder 17, piston'18, piston rod 19, bracket members 20, cylinder 21, piston 22, piston rod 23, tamping beam 24, sleeve brackets 25, rods 26, springs 27, leveler beam 28,
'cylinder 29, piston 30, piston rod 31, brackupon the roadbed B. The headers are usual- 1y wooden beams which are held in place along the margins of the roadbed by stakes or the like, as shown in Fig. 2.
Two side members 1 are provided which are held in spaced relation to each other, one
1 and 3.
The side members 1 are preferably arranged onthe outer sidev of their r tive wheels 12 so that the hopper 13, which extends the full width ofthe roadbed, may be mounted therebetween, as shown best in Figs. 2 and 3. The hopper 13 is mounted adjacent the forward end of the machine just rearover each margin of the road by cross mem.
wardly of the forward wheels. ,The hopper 13 is not only supported by the side members 1, but also by the cross members 2, 3, and 4.
-The forward side 13a pf the hopper slopes downwardly and rearwardly with a steep enough angle so that concrete or other paving material P, such as an asphalt composition, would readily slide to the bottom of the hopper. The rear side 13b of the hopper extends substantially vertically. The rear side 13b of the hopper does not extend so low as the forward side 13a. Mounted at the rear lower side of the hopper with its lower portion in substantially horizontally disposed relation to thelower edge 0f the forward vside 13a, and its upper margin overlapping the under side portion of the rear wall 13b of the hopper, is a cut-off member 14.
yThe cut-olf' member is in the form of a channel iron and is .mounted with its base portion in vertically disposed relation to'the rear side of the hopper so ,as to forma continuation of the rear wall thereof. Secured to the forward side of the cut-0E member; is a forwardly extending lip portion 14a, which extends the length of the cut-off member. As
above stated, the lower margin of the lcut-olii' member is flush with the lower margin 13a of the hopper. This llower side of the cutolf member is relatively wide and smooth. The ends of the cut-olf member portion extend past the end of the hopper, as shown in Figs. 2 and 3.
The'cross member 4, which extends across the rear side of the hopper 13, is in the form `of a' channel iron with the side walls thereof extending rearwardly. 'The lower side wall of the cross member 4 forms a track 4a, upon which ride hanger rollers 15, which are connected by suitable hanger brackets 15a to the cut-off member 14, so as to support the weight thereof. As roadways are given what is known as a crown or transverse curvature, it is necessary that the cut-olf member conform thereto. Thus, the lower margin of the cut-off member is arcuate, having its center of curvature at the same point as the road. The cut-olf member is adapted to oscillate transversely to the road. In order to maintain the cut-oil' member in proper relation to the road at all times, the track portion 4a of the cross member 4 is also made arcuate with its center of curvature at the same point as the roadway, as'sliown best in Fig. 2.
The cut-off member 14 is'prevented fromrearward movement b means of guide rollers 16 which engage t e rear side of the cutolf member, as shown in Figs. 1 and 2. The guide rollers 16 extend forwardly from the cross member 5. The cross member 5 is secured to the under side of the two side members 1, and extends therebetween in parallel disposed relation to the cutoif member 14.
Secured to the cross member 5, preferably at its central portion, is a cylinder 17, the
'from one or both sides.
longitudinal axis of which is horizontal and extends transversely to the roadway.
. vReciprocally mounted within the cylinder, is a piston 17, having a piston rod extending shown, there are two piston rods, one extending from each 'side of the piston. The ends of the piston rod 19 are connected to bracket members 20, which are secured to the rear side of the cut-off member 14. As shown in ,5
Fig. 2, the brackets 20 permit a slight vertical movement of the cut-off bar relative to the piston rods 19 so as to permit the cut-ofi` member to follow the transverse curvature of thel roadway within the limits of its oscillation.
The cross members 6 and 7 are located in spaced relation to the rear side of the hopper 13. These cross members extend in parallel disposed relation between the upper sides of the side members 1. Mounted in a vertical position, intermediate the ends of, and between, the cross members 6 and 7, -is a cylinder 21 having a piston 22 therein, which is adaptedv to oscillate and cause a like movement of a piston rod 23. The piston rod 23 In the structureextends below the cylinder 2l and is secured to the upper side of a tamping beam 24. The beam 24 is made as heavy as possible and extends transversely to the roadway, as shown best in Fig. 4. V
' The ends of the tamping beam reach to the sfide margins-of the roadway. Secured to the'inner sides of the side members 1 is a pair of sleeve brackets 25, each of which is adapted to receive a vertically extending rod 26. `The lower edge of each rod 26 is secured to an upper end portion of the tamping beam bers 6 and 7 may be provided with suitableY l bracing 6a and 7 a, as shown\il1 Figs. l and 3, but omitted inFig. 4.l y
Rearwardly of the rear wheels 12, there is provided a leveler beam 28. This beam is in the form of a relatively thin plate, which conforms to the curvature of the road, and extends between the margins thereof. The
beam is adapted to rest by its own Weight upon y the road.
The cross members 8 and 9 extend between the lower end portions of theside members 1 and are vsecured to the under side thereof. The cross members 8 and 9 are arranged in parallel disposed relation and support at their central portion a cylinder 29, the axis i` of which is vhorizontal and-extends transbrackets 32 extend upwardly from the leveler beam 2 8. As shown in Fig. 5, the brackets 32 permit slight vertical movement of the leveler beam 28 .as said beam follows the curvature of the road in its oscillation.
The cross members and 11 are arranged in parallel disposed relation to each other and extend between the upper sides of the side members 1 .just forwardly of the rear wheels 12 and rearwardly of the cross members 6 and 7 as shown in Fig. 1. Supported at. the one end of the cross members 10'and 11, is
an engine 33. Driven by the engine 33, and
also supported by the cross arms is an air compressor 34. A compressed air, storage reservoir '35 mayalso be supported upon these cross members. The en ine 33 is connected by suitable gear and s aft means V36 to the several wheels 12, preferably all four wheels so as to give the best possible traction. This may be done, as shown in Figs. l and 3, by gearing directly to the front and rear wheels on one side 'of the machine, which, in turn, are connected by their'lshaft's 12a, to
y the wheels on the opposite side.v
The compressor andreservoir deliver air vto supply pipes 37, which connect through valves 38, to the various cylinders 17,21 and 29. The valves, together with a clutch lever 39 and other controls for the engine 33, may
all be arranged soas to be operated from an operators platform 40 mounted between the cross members 6 and 4, at the one side ofthe machine, as shown in Figs. 1 and 3.
'I he operation of' my machine is as lows:
The paving material yP is poured into the .fol-
. hopper 13. As the machine moves along by reason of the wheels rolling on the headers H, the paving material is ,caused to flow out the bottom' end'of the hopper between said headers. During this movement, the cut-oit member 14 oscillates back and forth, causing the paving material to work the ull vdistance between the headers, levelling the surface of the paving, and preventing too large a deposit. Simultaneous with this movement, the tamping beam is caused by the cylinder 21 and piston 22 to oscillate in a vertical plane and pound or tamp the paving material firmly so as to pack the various particles thereof into closer bond. At the same time, the leveler beam 28 smooths oif any irregularities in the paving caused by the action of the tamping beam. Thus, the pouring, spreading, tamping, and leveling of the paving is all accomplished in practically one continuous operation. v
Though I have shown and described a parl -ticularconstruction, combination and ararrangement of parts and portions, I do not- Wish to be limited-to this particular construction, combination and arrangement, but
desire to include in the scope of my invention the constructlon, combination and arrangement substantially set forth in the appendedv claims. Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
