Application filed June 22, 1920.

To all whom it may concern:

Be it known that I, JosEPH WV. OURADNIK, a citizen of the United States, residing at Kewaunee, in the county of Ke'waunee and State of Wisconsin, have invented certain new and useful Improvements in a Snow Plow and Roller, of which the following is a specification.

This invention relates to road machines and more particularly to a snow roller and road grader, the primary object being to provide a machine of this character which may be employed to keep the roads in good condition at all times during the year.

One of the objects of the invention is to provide a machine for rolling the snow on roads and highways so that it will be firmly packed down whereby a firm surface will be provided so that trafiic will not be interrupted.

Another object of the invention is to provide a machine of this character which will operate in the manner similar to an ordinary tractor so that a relatively wide surface may be operated on by the machine while it is in use.

The invention further aims to provide a machine of this character which will be provided with power mechanism for moving the machine and which will he so construct ed as to permit it to be used while the snow is falling so that the snow may be packed as it gathers on the ground.

Another object is to provide tractor machine which may be employed as a plow to remove soft snow when desired so that the roads may be cleared when the snow softens and begins to melt.

A still further object of the invention is to provide a tractor machine adapted to be used as a road grader for keeping the surface of the road in proper condition.

The invention also contemplates the provision of means which will co-operate with the tractor to improve the condition of the road surface so that material forming the covering for the road may be kept free from ruts and unevenness and generally improve the surface of the road.

Other objects of the invention will appear upon consideration of the following. detail description and accompanying drawings, wherein:-

Figure 9 is a fragmentary plan view showmg a plow adapted for attachment to the machine and Figure 10 is a perspective view of a brace member adapted to be used with the plow.

Referrlng to the drawings by numerals, the sub-structure of the machine is adapted to support a housing within which the main mechanism is arranged as generally illusrated in Figs. 2 and 3 of thedrawings. The sub-structure comprises longitudinal frame bars 1 preferably I-beams having their forward ends extended upwardly at an angle as indicated at 9.. Mounted upon the frame bars 1 are bearings 3 which receive trans-' verse shafts lhaving gear wheels or sprockets 5 mounted thereon. The sprockets are relatively large in diameter and extend below the lower marginal edges of the frame bars 1. Carrier chains 6 are trained over the rearmost sprockets and are engaged by the other sprockets and the chains also engage smaller sprockets 7 journaled in the end portions of the angular ends 2 of the frame bars. Shafts 8 support the sprockets 7 so that a portion of the forward end of the chain is extended upwardly at an angle as shown. Attached to the chains are the transversely extending plates or cleats 9 which have their edges close together but which are separately mounted on the chain so that the tractor thus formed is free to travel when the gears are set in motion. Ordinary calks are adapted to be mounted in the cleats if desired.

As shown to advantage in Figs. l and5 the tractors consist of two separate units ar- .1 Eli.

ranged relatively close together but since they are of the same construction the above description of the mechanism is applicable to both.

Standards 10 are mounted upon the frame bars 1 and support a main platform 11 which also forms the flooring for the body of the tractor which supports the driving and operating mechanism. This platform has a large roomy housing built thereon pro vided with windows arranged in any preferred manner whereby the operators of the tractor may be protected from the action of the elements during inclement weather.

Referring particularly to Fig. 2, a gasoline engine 12 is mounted upon the platform and it will be obvious that any type of engine or motor may be employed. A drive shaft 13 from the engine is provided at one end with a beveled gear 1a in mesh with a beveled gear 15 which drives a transmission shaft 16. The shafts 4: for the tractors are independently mounted and are adapted to operate at one side inedependently of the shafts at the other side. The real-most shafts a are provided on their outer extended ends with sprockets 17 over which chains are trained as indicated at 18 and these chains are engaged with sprockets 19 on the extended ends of counter shafts 20 supported in bearings within the housing. The inner end of each counter shaft 20 is provided with. a beveled gear 21 each of which meshes with a beveled gear 22 on the end of one of a pair of auxiliary shafts 23. Each auxiliary shaft is also provided at its opposite end with a small beveled pinion 2 1 and a larger beveled pinion 25. Slida'bly mounted driving gears are arranged on the trans mission shaft 16 and these include a set of gears for each pair of gears 24 and 25, the larger beveled gear 26 being adapted to mesh with the larger beveled pinion 25 while the smaller drive pinion 27 is adapted to mesh with the smaller beveled pinion. 24. The two beveled gears 26 and 27 are connected together in any suitable manner as by a sleeve 28 and this sleeve is slidable on the shaft 16 with the gears 26 and 27 so that when the gear 26 moves out. of engagement with the pinion 25, the gears 27 will move into engagement with, the pinion 2 1. This will permit the speed of the tractor shaft to be changed when desired and it will be noted that the arrangement will permit the shafts to be operated in opposite directions for reversing one of the tractors when it is desired to turn quickly. These sleeves 28 are adapted to be operated by suitable levers 29 pivoted as indicated at 30 and reaching to a point within convenient reach of the op erator of the machine.

With the above mechanism it will be readily appreciated that the snow on the surface of the roadway may be quickly rolled and packed so that a firm surface will be provided to assist traffic. The machine may be operated while the snow is falling so that it is firmly packed as it gathers on the ground.

The mechanism for using the device as a road grader comprises a scraper blade 31 having a reinforced edge piece 32. This scraper blade is attached to upright supports 33 which are extended through openings in the ends of movable beams 34. These beams are extended longitudinally into the housing and are movable through casings attached to the platform so that longitudinal adjustment of the beams will be permitted whereby the angular positions of the scraper blademay be changed. This is accomplished by providing the beams 23% with rack bars 35 adapted to be engaged by rack pinions 3t and 37. A transverse shaft 38 is provided with a beveled gear 39 in mesh with a beveled gear 40 on a hand wheel shaft 41 which is provided with a hand wheel 42 whereby the shaft may be manually rotated. A gear as on one end of the shaft 38 meshes with an intermediate gear 44. on an intermediate shaft and the gear a l meshes with the rack gear 36 the latter being mounted on a shaft 4-6. This will cause the right hand beam 34 to move in either direction according to the turning movement of the wheel 42. The opposite end of the shaft 38 is provided with a gear 4:8 which meshes with the rack pinion 37, the latter being on a shaft 49. In this instance no intermediate gear is provided so that the direction of rotation of the gear 37 will be exactly opposite to that of the gear 36 when the hand wheel is turned in one direction. This will cause the left hand beam 34 to move inwardly when the right hand beam 3st moves outwardly. It will be obvious therefore, that by turning the hand wheel 12 the angular position of the scraper blade 31 may be quickly changed.

It is also desirable to have the scraper blade tilted longitudinally at certain times and this is accomplished by moving the supporting standards 33. Each standard 33 is slidably mounted in one end of the corresponding beam 3 and has a rack bar extending longitudinally on its inner side. This rack bar is engaged by a rack gear 51 on a shaft 52 supported in suitable bearings and extending into the housing where its inner end is provided with a hand wheel 53. The gear 51 for each supporting member 33 maintains its relative position with respect to the rack bar by virtue of its engagement therewith but the shaft is keyed to the gear in a manner that will permit longitudinal movement of the gear on the shaft so that the mechanism provided for lifting either end of the scraper blade will not interfere with the mechanism for providing the angular adjustment of the blade. It will be obvious that by turning either of the hand wheels 53, either end of the scraper blade may be raised or lowered.

In Figs. 7 and 8 I have illustrated a mech anism which may be utilized to lock the beams 34 if the lock provided by the engaging gears is not sufficient. This lock comprises a foot pedal tilted as indicated at 56 on a pivot and connected to a double pawl 57. The latter consists of arock shaft 58 having an extension 59 connected as indicated at 60 to the foot pedal while the opposite ends of the shaft have the locking pawls 61 adapted to engage the rack bars 35 on the beams so that when the beams are set in the desired position the same may be locked. Obviously any other suitable locking means may be provided for this purpose.

Figs. 9 and 10 illustrate a plow attachment which may be employed if desired. The sides of the plow are formed of plates or blades 65 hingedly connected as indicated at 66, this hinge forming the apex or point of the plow when it is in use. A brace bar 67 has its ends engaged with the inner surfaces of the plow plates 65 and is held in position by angular connecting cleats 68 adapted to be removed when the plow is to be disconnected so that the plates 65 may be folded on the hinge connection 66 to be packed in a relatively small space when the plow is not in use. A central brace member 69 is provided which has a connecting bar 70 adapted to be removably connected to the upright members 33. A central brace bar 71 extends forwardly from the bar 70 and terminates in a finger 72 adapted to engage the hinge connection 66 so as to provide a firm brace for the point of the plow. It will be understood that the details of this mechanism for connecting the plow may be varied according to the scope of the appended claims.

It will be noted by referring to Fig. 1 that a coupling link 74: is attached to the rear of the platform. This is forthe purpose of providing a coupling for connectingany trailer to the machine and it is pointed out that the invention contemplates the provision of a heavy cylindrical roller weighted down in the manner common to devices of this character so that the roller will assist the tractor in providing a firm surface for the roadway.

From the above it will be observed that the mechanism includes a very practical and efiicient all year road machine and I desire it to be understood that I do not limit myself to the exact details shown and described but prefer to make such changes in the details of construction as fall within the scope of the appended claims.

What I claim is 1. In a road machine, the combination of a frame structure, a platform mounted on the frame structure, adjustable supporting beams mounted on the platform, means to manually move the supporting beams independently of each other and means to support the scraper blade from the supporting beams.

2. In a road machine, the combination of a frame structure, a platform mounted on the frame structure, forwardly extending beams carried by the platform and slidably mounted to move forwardly and rearwardly independently of each other, independent operating means for each supporting beam adapted to be manually operated, vertical supporting elements carried by the forward ends of the said beams, a scraper blade attached to the said vertical supports and means to independently adjust the vertical supports to raise and lower either end of the said scraper blade.

3. In a road machine, the combination of a frame structure, a platform supported on the frame structure, supporting beams extended forwardly from the platform and slidably mounted thereon, a rack bar on each beam, and manually operated means to move the said beams in opposite directions when the said manually operated means is actuated and a scraper blade supported from the said forward ends of the beams.

4.. The combination with a road machine, of a tractor, a platform supported by the tractor, a scraper blade, means supporting the end of the scraper blade to hold the latter edgewise, a rack bar formed on each supporting means, and gears engageable with the raclr bars to move the supporting means vertically whereby the opposite ends of the scraper blade may be raised and lowered.

In testimony whereof, I have afiixed my signature in the presence of two witnesses.
