Application filed August 29, 1927. Serial No. 216,298.
My invention relates primarily to a machine for refinishing paved roads and comprises mechanism and means for operating the same for planing off the bumps or projections formed in thepavement by thepassage thereover of heavy traflic or otherwise,
side members and 16 near one end are standards and 20 in which are proand using the material planed off to fill the depressions in the pavement, and this application is a new application covering the in- 10 vention as originally described and claimed in the afiiplication filed April 2, 1923, under Serial umber 629,379.
It is the object of my invention to provide a machine for the a ove purpose which 15 will be simple in construction and very efficient in 0 ration.
'Other 0 jects and advantages will appear hereinafter and. while I have shown and will describe the preferred form of my invention, it will be'und'erstood that I do not limit myself to such preferred form but that various changes and adaptations may be made therein without departing from the spirit of my invention.
In the drawings accompanying and forming a'part hereof:
ig. l, is a side elevation of my machine ready for use. V Figl2, is a top plan of Fig. 1. Fig. 3, is an enlarged side elevation, partly in section, of the planer roll shaft bearing. F Fig. 4, is a section on the line 4-4 of ig. 5, is an enlarged vertical section,
partly in elevation, of the planer roll elevating bearing and mechanism.
Fig. 6, is a transverse section through F i 5, 'ust beneath the bevel gear.
Fig. i, is an enlarged side elevation of the planer roll detached from its place of use. 4 Fig. 8, is a left hand elevation of Fig. 7.
Figs. 9 and 10, are respectively, a side elevation of one of the cutters used with my device with its mountin in section, and a right hand elevation of ig. 9.
Fig. 11, is a perspective view of one of my cutters. Referring to the drawings my machine 50 comprises a carrying frame, preferably rectangular in top plan and being composed of side members 15 and 16 connected together at their ends by cross members 17 and 18. The ends of the side members 15 and 16 are beveled at the'lower corners the ob'ect of which will be readily apparent an these side members are also shod with replaceable shoes 19 which take the wear. Suitable cor-- ner and other braces may be provided to provide the necessary strength and rigidity, but are not shown to provide clearness of illustration. Extending upwardly from vided verticall extending guideways 21, 21, the upper en of these guideways being closed by vertical bearings 22 and 23. R0- tatably mounted in bearlngs 22 and 23 are bevel gears 24 and 25 which gears are provided with elongated hubs, the lower ends of which project beyond the lower ends of said bearings 22 and 23 and have provided thereon collars 26 which serve to prevent upward movement of said gears relative to said bearings. Gears 24 and 25 are interiorly screwthreaded for engagement with the scr ewthreaded upper end of the elevating sbrews 27 and 28. The lower ends of said screws 27 and 28 are slidably but not rotatably mounted in bearings 29 provided in the upper ends of the elevating carriages 30. Carriages 30 are slidably mounted in the guidewa s 21, 21, to slide vertically and are provide intermediate their len h with opposed bearings 31 and-32 and 1n these hearings are rockably mounted the pintle's 33 and 34 projecting outwardly from opposite sides of the planer roll shaft bearings 35. The planer roll shaft 36 is revolubly mounted at its ends in the bearings to extend transversely of the carrying frame; and
rigidly mounted upon said shaft, between the side members 15 and 16 and at equally spaced distances are the discs 37. Rigidly secured to the outer periphery of discs 37 at equal] extend spirally are a plurality of cutter holding bars 38. Each of these bars is provided upon its outer face with a plurality of s aced substantially square sockets 39 and in tiiese sockets are mounted the cutters 40. Cutters 40 are preferably square in transverse section, have their outer ends beveled on one side to form a chisel point and have their other ends reduced in size to fit the sockets 39. These reduced ends project beyond the sockets 39 and are provided with tapered slits therein for the reception of tapered keys 43, cotter pins 44 being used to prevent displacement of said tapered keys accidentally. It will be noted that the cutspaced distances around the same to ters 40 are so positioned upon their respective bars 38 that, when said bars are positioned for use the said cutters will be positioned in staggered relation to each other, the object being to have one cutter only effective at a time, but that the next adjacent cutter will begin to cut as the previous cutter finishes its out and producing in effect a continuous cutting operation with the minimum effort and expenditure of power.
Rigidly mounted upon shaft 36 at the inner ends of the bearing 35 are sprocket wheels 45 which are operatively connected by chains 46 to sprocket wheels 47 rigidly mounted upon a shaft 48. Shaft 48 is revolubly mounted at its ends in bearings 49 and 50 mounted at opposite sides of the frame and has rigidly mounted thereon, near one end a pulley 51. Pulley 51 is operatively connected by a belt 52 to a pulley 53 rigidly .mounted upon one end of the drive shaft 54. Shaft 54 is adapted for connection to the shaft of the prime mover 55 by means of a clutch 56. A lever 57 provides means for" manually qonnecting shaft 54 to the shaft of the prime mover 55 by operating the clutch 56. Secured at one end to the upper end of the standards 20, 20 to project angularly therefrom are brackets 58 and 59, at each end of which are provided bearings 60 and 61, and in these earings are revoluhly mounted shafts 62 and 63 on the outer ends of which are rigidly secured hand wheels 64 and 65 by means of which said shafts may be manually rotated. Rigidly mounted upon the inner ends of shafts 62 and 63 are bevel gears 66 and 67 which are in mesh with the bevel gears 24 and 25 so that as wheels 64 and 65 are retated to rotate shafts 62 and 63, gears 66 and 67 will rotate gears 24 and 25 and raise or lower screws 27 and 28 and with them the carriages 30, thus raising or loweringthe planer roll shaft and its complement parts. A suitable flooring or decks 68 and 69 will connect the upper ed es of the side members. A scra er member 0 is mounted beneath the dec 68 to extend angularly and serves to scrape the surplus planed material to the side of the roadbed.
In operation the sitions shown.
The relative ratio between the prime mover and the shaft 36 is such that the said shaft 36 will rotate at a high speed and as the device is drawn along the pavement in any suittable manner the cutter teeth will plane off or sever the bumps or projections, the scraper acting to scrape the severed'material into any depressions and the surplus to the side of the roadway. By rotating the hand wheels the height of the cutters relative to the roadway may be regulated or the cutters may be elevated from contact entirely when desired.
The object in having the lower ends of the parts will be in the poelevating screws 27 and 28 slidable in the bearings 29 of the elevatin carriages 30 is to permit the planer roll s aft 36 and its associated parts to raise in the event an obstruction is encountered which the cutters are unable to handle. Either end of the shaft 36 may be raised independently of the other end due to the bearings 35 being rockably mounted in the carriages 30.
Having described my invention what I claim and desire to secure by Letters Patent is:
