The present invention relates to improvements in stone spreading machine, and has for an object to provide an improved machine for use in the spreading of stoneor macadam roads or for the base courses of roads.
The machine will find a wide use in connection with the retreading of old macadam roads where it is required to spread stone coated with tar or asphalt; and such machine is also so designed that it may be used for the building of sand asphalt rcads or for thespreading and leveling of materials which are mixed in place. Y
The invention further aims to provide van improved machine for leveling the berme or dirt shoulder at the sides of the road.
With the foregoing and other objects in view, the invention will be more fully `described hereinafter, and will be more particularly pointed out in the claims appended hereto.
In the drawings, wherein like symbols refer to like or corresponding parts throughout the several views,
Figure 1 is a perspective view of an improved stone spreading machine constructed in accordance with the present invention and shown in aposition of use. A
Figure 2 is a similar view, withv parts broken away and taken on an enlarged scale.
Figure 3 is also a fragmentary perspective view with parts omitted to more clearly show the reciprocating devices.
Figure 4 is a fragmentary perspective view showing the forward portion of the machine.
' shown in section and parts broken away of the motor and driving devices, and f Figure 7 is a perspective view showing a modied form of apparatus.
Referring more particularly to the. drawings in Figure 1, I designates the subgrade or the base of a road, and Il represents crushed stone, slag or other desired material which is to be spread .upon the subgrade I0 by the machine. Such material may be either plain or saturated with tar or rasphalt material; and it will preferably be delivered upon the subgrade in a windrow substantially centrally of the road. Ifpreferred such material may be roughly spread over the subgrade when it is rst deposited.
Y The improved machine is supported on side runners or skids I2. which support a desired number of transverse members I3 and I4 by which the runners are tied together to constitute a machine frame 'for carrying the various machinery required.A n .y
The machine is pulled forward by the use of cables l wound about drums I6 carried on the machine andmounted upon the transverse fol- 5 lower shaft I1 which is mounted in appropriate bearings carried upon the short longitudinal beams I8. f g
The forward ends of the cables l5 are secured to the anchors I9 which anchors are fastenedby the stakes to the subgrade l0 in advance of the machine. K
The machine carries its own -power plant or motor 2l mounted at a convenient position upon the machine frame and having appropriate connections for driving the various mechanical agencies hereinafter referred to as well as the shaft Il andthe drums I6.` By rotating the shaft I1 and the drums I6, the cables l5 will be wound upon the drums thus pulling the machine for- 20 ward. At the same time the various .leveling members are reciprocated laterally in order to accomplish the even and uniform distribution of the stone throughout the area of the roadway.
At the front ofthe machine is carried a rudder or deecting member 22 supported and rotatably mounted about lthe pivot 23 on the up-` per end of which is fixed a collar 24 for supporting the pivot and the member 22 upon the bearing sleeve 25, which bearing sleeve is bolted or otherwise aflixed to a front plate 26 fixed upon the machine frame, as upon the forward part of a platform 21 carried upon the' convergent angle iron or braces 28 forming part of the frame.
'Ihe cap collar 24 is provided with an arm 29 to which is pivoted a link 30 engaging a hand lever A3| pivoted, as indicated at 32 upon the front plate 26, as shown in Figure 4.
A removable pin 33 upon the lever 3l is insertible in a selected perforationv 34 of an arcuate series of perforations made in the front plate 26, whereby the lever 3| may be held in the desired angular adjusted position. By moving this lever 3| backV and forth about its pivot 32, through the link 30 and arm 29 a rotary movement will be imparted to the pin 23 and the rudder. or deiiecting member 22 causing the same. to assume a desired angular or straight position with`respect to the forward movement of the machine, thus defiecting the stone material from the windrow to one side or the other. The pin 33 will lock the lever and the rudder in the adjusted position, whereby there will be an equal distribution of the material on the roadway.
The rudder `or deecting member 22 is also ca- `pable of a lateral movement by manipulating the hand wheel 35 which hand wheel, as shown in lFigure 4, is mounted upon a transverse shaft 35 ward part of the platform 21, as indicated at 42 in Figure 4.
In rear of the defiecting member 22 are a pair of curved blades 43 converging forwardly and meeting in a central ridge 44. These curved blades are connected together and also lto a laterally reciprocating leveling or screed member 45 This which projects through the side runners. leveling unit, consisting of the two blades 43 and screed member 4,5 is adjusted up and down-by means of a central screw threaded adjusting device 45 and side adjusting devices 41 in order to accommodate the device to various thicknesses in the spreading of the stone `asmight be re-y quired.
As shown in Figure 5 thev central hand wheel or adjusting device 45 is mounted uponra screw threaded shaft 45 movable up and down by rotation in the supporting nuts 49 carried upon one of the beams I5 of the framework. At its lower end the screw adjusting shaft 45 carries a universal joint 5I)v connected by a link 5I Lto a brace 52 secured to the blade 45. The universal joint will permitof `the lateral reciprocation of the unit while' acting to suspend'same and effect vertical adjustment. y
TheA machine is also provided -with material conveyors 551 which are trailed-on the inside -of the machine by the chains 54. l 'Ihese conveyors hold excess stone material, which accumulates forwardly of the spreader 43. Such surplus material will be trailed or moved along or conveyed by the conveyors 53 to be discharged therefrom at points along the roadway where there. is in- Y sufficient material caused by the unequal depositing of the stone or the material on the subgrade.
The screed or surfacer 45 is reciprocated laterally by the eccentric 54, which is on the shaft 55 driven from the motor or power planty 2| by appropriate gearing.
'I'he eccentric 54 is connected toa rod 55 as shown in Figure 3 which rod is coupled to the depending arm 51'on a shaft 55. `To the arm 51 is also coupled-'a rod 55 extending over and pivoted to the spreader or screed member 45.
The machine is also provided with a laterally reciprocating member 55 crowned to conform to the top surface of the iinished'stone surface,
which member may consist of a heavy beam roughened more or less at its forward surface. so as to engage the particles of stone and agitate the stone and manipulate the various particles of material in such a way asto key the stone in position. While this member will serve as a surfacer, it will also locate or key the stone in-posi` tion so that the various particles `of vstone are overlapping, causing the stone to be yplacedr in the keyed position, producing a cross section which will be asfree from voids as possible, and
' securing a homogeneous structure, which, when finally rolled and compacted, will be free from pockets or depressions as has been the case when the stone material has been loosely laid.
'I'he member 55 projects through the side members of the machine in which are inserted vertically movable plates or slides 5I movable up and down by thehand wheels 52 through the action of the screw adjusting shafts 53. The keying member projects through an opening in the plate 5I whereby the keying member 50 may reciprocate and at the same time be capable of vertical adjustment. The keying member 50 is reciproc'ated as 'shown in `Figure 3 by the eccentric 54 through the rods 55 and 55 and the arm 51.
The keying member 5I) can'ies one or more grader blades 55 lying outside of the runners of the machine for the purpose of planing down the dirt shoulder on the outside of the runner. 'Ihe dirt shoulder after being cut down is indicated in Figure 1 at 59.
In order'to deflect any surplus stone which might accumulate on the inside of the runners, I have provided the adjustable wings or plates 15 pivoted to the runners or to other appropriate parts as for instance upon the screwA adjusting shafts 1I and areadjusted up and down from the hand wheels 12. The free ends of these wings or plates are held in place by chains 13 attached to appropriate parts of the framework.
Additional wings or plates 14 are provided extending outwardly of the runners and mounted upon the screw adjusting shafts 15 by which the same may be raised or lowered. These wings or plates 14 act as additional shoulder scraping devices or they are employed for shoulder building or for leveling. The chains 15 hold the blades 14 to various angular positions. When it is required to move dirt away from the runners, the members 14 will be allowed to swing back in an angular retreating position with respect to the runnersdeecting the material away from the runners. When such blades 14 are pulled forwardly by shortening the chains 15, so that such blades assume avforward angular position, the material will be directed toward the runners.
The runners are provided with bas portions I2a which are cut away at the points indicated at I2b. 'I'his removal will minimize the agitation of the dirt shoulder after it has been thrown against the outside of the runner attended by a reduction in the cleft 11 between the dirt shoulder and the stone to a minimum width, whereby there will-be very little or no slumping of the material into the cleft.
To manipulate the machine on curves, provision is made for warping or deilecting'the forward reduced portions of the runners I2 as indicated by dotted lines in Figure 1, and to this end radius rods 15 are secured tor the runners I2 and to a lateral sliding plate 19, as shown in Figure 4, such plate being provided with slots 55 to receive therethrough the fastening means or guide members 5I which confine the plate to permit its lateral sliding movement under the direction and action of the hand `lever 52 pivoted at 53 upon the plate 54 and having a pivotal connection to the plate 15 as indicated at 55. The radius rods 15 will be rigid enough to exert pressure against the runners to force the runners out or pull the same in as the case may be in rounding a curve. By manipulating the lever 52 the runnersmay be curved or warped to a limited extent so as to negotiate the curvein the roadway.
l Itwill also be understood, as shown in Figure 6, that separate clutches 55 and 51 upon the shaft I1 are provided for coupling either end of that 75 shaft and its entrained cable drum |6 or for operating both drums simultaneously. Either drum may thus be operated independently of the other which arrangement will be additionally desirable in negotiating curves. The drums will be connected for united operation when the machine is driven in a straight path. It is to be understood that the machine is assembled in units that may be easily handled to and from the work.
Referring more particularly to Figures 2 and 4, the power plant 2| is shown as having a shaft 90 carrying a sprocket '9| engaged by a chain 92. 'I'his chain 92 is also engaged with a sprocket 93 on a shaft 94. On this same shaft is a sprocket 95. Between the sprockets 93 and 95 isa clutch 96 for throwing the entire mechanism out. of operation when desired.
The sprocket 95 is engaged by a chain 91 which runs over a sprocket 98 on the eccentric shaft 55. A worm 99 on the eccentric shaft engages a work Wheel |00 on the intermediate section |0| of the drum line shaft. The end portions Il and Ila of.
the drum line shaft which are ilxed to the drums I6 have clutches 86 and 81 for engaging the same either simultaneously or individually with the center shaft section |0| which is driven by the power plant 2| through the train' of gear connections outlined.
'I'hescreed 45 in a manner similar to the keying member 60 extends slidably'through vertically adjustable plates |02 which are made adjustable by means of the hand wheels 41. 'These adjustable plates 42 slide in guideways |03 lprovided upon the side runners of the device. y
`In operation, the power lplant 2| will draw the machine forwardly 0n the runners I2 by winding the cables I5 upon the drums I6 when the various clutches 86, 81 and 96 are engaged. The crushed stone or other material is dumped upon the subgrade |0 in a windrow or otherwise. As the machine proceeds, the deflecting rudder 22 will p ass through the stone dividing the same and deflecting it to one side or .other of the rudder. The rudder may be angularly adjusted about its pivot pin 23 to deflect the stone more Ato one side than the other if desired, and the rudder may also be adjusted laterally through the action of the hand wheel tov bring it to a desirable position with respect to the lateral line of the roadway and machine. 1
vAs the machine follows along the spreader members 43 will encounter the stone and will act to spread` the same outwardly toward the runners |2, such action being facilitated by the transversely recprocatory movement given to the spreading blades 43 by the actionI of the eccentric' 54.
' The screed 45 which forms a unitary structure with the curved spreading blades 43 will also act to smooth down the stone to the proper surface level which level will be uniform throughout the entire surface of the roadway.
There follows the keying member which will compact and key the various stones into the road in overlapping relation with one another, which action is also considerably enhanced by the reciprocating movement given to this keying mem-l geneous whole and this resultfwill be accomplished quickly and inexpensively with the improved machine.
Referring more particularly to Figure 7, theA retreading material is indicated at as having i been placed over the old road bed |0 and extending outwardly beyond the sides thereof to build up and widen the old road.
It will be understood that the substance usedl for the retreading may consist of any suitable material, such as tar or asphalt mixed with stone or any other desired material. It will furthermore be understood that even` concrete could be used for this purpose but it is more particularly adaptable for spreading a bituminous type of material. In the forepart of Figure 7 it is clearly brought out how the road has been widened and a thickened edge ||2 has been constructed to form a curbing or header beyond the 'sides of the old road ||0.
'Ihe operation of the machine is substantially the same -as heretofore described. the stone, or other retreading material, being indicated at ||3 and being deposited upon`the old road ini advance of the machine. Spaced apart so as to rest directly upon the old road bed ||0 are runners or longitudinal skids 4 `which sustain the spreading machine and its operating parts to the proper elevation. In the previous forms of the invention, the skids or runners were operated on the berm or dirt shoulderof the roadway; whereas the runners ||4 operate directly on the top Aand bolts ||9 or other appropriate fastening means. Such side wings ||6 and their supplemental wings ill do'not support themachine and are spaced apart a distance substantially equal to the width required for the resurfaced road. Adjusting screws |20 are mounted through the wings i6 and carry the supplemental wings ||1 for the purpose of raising and lowering the same. These adjusting screws |20 may also be used as thesuspending means for the supplemental wings ||1, the bolts ||9 being used as mere vguide means. The form is supplied with cross braces |2| to hold the machine in position. In the runners ||4 are openings |22 through which the V-shaped spreader' |23 and the transverse surfacer |24 project. The wings ||6 are provided with similar openings |25 and thesupplemental wings ||1 are formed with openings orcut-away portions |26 through which the ends of the transverse surfacer member |24 project.
The resurfacing or retreading material is shown at H3* as being deflected by the vshaped spreader |23. The material is projected by the spreader through the openings |22 in the runners H4, and this spreading or deflection of the material continues until such material comes 75 into contact with the outside wings ||6 and 1, which limit the lateral spread of the material. It will be understood that this spreading operation is done simultaneously as the spreading ma.- chine is pulled forward by the cables |21 which are attached to a tractor, truck or other suitable means.
The skids or runners III will produce a channel or groove in the material, and in order to close up the groove rearwardly of the runners, the final surfacer |28 operates on the material to take care of the final spreading or surfacing operation. The surfacer |28 projects through the openings |29 in the supplemental wings |i'l and is adjusted up and down by the hand screws |30. Hand screws |3| are also provided for adjusting the forward spreader |24 up and down or as to height. The runners lil may be provided with the gates |32 to regulate or retard the flow of the stone ||3 through the forward portions of the openings |22.
The gate is pivoted at |33 andv is adjustable by a wing nut`and bolt arrangement |34 projecting through an arcuate slot |35 in the plate |32.
It will be understood that these surfaces may be reciprocated if desired; however, in most cases it will not be necessary to reciprocate the spreaders and particularly inasmuch as the machine described herein is drawn by a truck or tractor, it would not be desirable to reciprocate the spreaders.
It is obvious that various changes and modifications may be made in the detail of construction and design of the above specifically described embodiment of this inventionl withouty departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims. t
