ROAD nrtnssnn.

Application filed July 21,

' creasing the draft of the machine incident to such accumulation.

Another object is to provide a machine of this character constructed so as to loosen the road material and push it over tofill in 10W places and past the center of the'machine if it, is not needed to 511 up'low places and should there be a small amount of road material pushed out at the side of the path passed; over it will be smoothed down and" leveled during the passage of the ma'chine thereover;

Another object is to provide aroad dresser having grader blades arranged so that they will fill ruts, ditches and the like from both sides during the passage of the machine in one direction and having means to prevent dipping of the machine and to produce an even distribution of the road material.

With the foregoing and other objects in view which will appear as the description proceeds, the invention residesinthefcombination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be madewithin the scope of what is claimed without de parting from the spiritof the invention.

In the accompanying drawings: I Figure 1 represents a top plan view of a road dresser constructed in accordance with this invention. I

Fig. 2 is a side elevation thereof with the rear portions of the'runners broken away.

Fig. 3 is a bottom plan view thereof. Fig. 4 is a longitudinal section taken on the line H of Fig. 1 and Fig. 5 is a detail transverse section taken on the line 55 of Fig. 1.

In the embodiment illustrated the machine constituting this invention comprises laterally spaced runners 1 and 2 connected by in- 192a serial No. 652,966. a

termediate spaced cross bars 3 and 4; and a rear cross bar 5 which carries a smoothing.

blade hereinafter to be described; A. rod 6 i also connects the reariends ofthe runners at a pointadjacent the bar 5 and is threaded at one end and provided with nut to adapt it to be used for clampingly connecting the runners in engagement withthe blade carrying bar 5 whlch is located between the runners withits ends abutting the inner faces thereof. A' scarifier 10 is mounted at the front end of the machine between the runs ners land 2 and is composed of twobars or beams 11 and .12 located in recesses 7 formed in the inner faces of the runner-sf Thesebars:

11 and'12- are clamping-1y connected by bolts 14 and haveiarranged between them teeth 115 any desired'number of which may be em;

ployed and whichmay be of anysuitable or desired shape for: loosening up the road material in connection with which the machine,

is to be used.

A metal strap .13 extends acros sjthe-front' end of the machine around theqscarifier 1O and the outer faces of the ends'of the r'unners 1 and 2' and are secured by a rod,1-6;

passing through the runners adjacent the scarifien: Clevises'or clips 17 are mounted on'the ends of the -rod 16 outside the runners and have connected therewith a draftchain 18 designed'to-be attached to any suitable draft means suchas a tractor or the like.

the inner faces of the runners1and'2 respectively and inclined rearwardly, and in Grader blades 19 and 20 are mounted on runner blade 20 extends at its rear end he 7 'yond the rear end of blade .19 in a plane lapping the plane occupied by' blade 19 and is attach d 2 by a brace 9;.

' .The blades 19 and 20 are carried by beams to cross bar 4 and braced to runner I scraping action when the machine is drawn over the road. v

The bar 5 is polygonal 1n cross sectlon and its inner face is inclineddownwardly and rearwardly and has securedthereto in.

smoothing blade 25 which is attached to I i any suitable manner the smoothing blade 25 the lower edge 26 of which projects beyond the bar and slightly below the surfaceengaging faces of the runners 1 and 2 .so that any material pushed out at the side ofthe path passed over by the second grader 26 will be smoothed down and leveled by the the runners at right angles and is not intended to out new material butmerely to articles. i

level the lo0se V 7 this" machine it In the use 0 should be drawn so that-the rut or low place to be filled in will be located directly under the implement atabout the center thereof. In

the movement of the machine over the roadway the scarifier 10 will loosen the road materialso that the grader blades 19 and 20 following it willpush theloosened ma terial into the rut or low place. The front blade 19 will'push the loose material into the rut some of it perhaps going overthe rut and then the following-blade 20 will push the loose material from the other side into or over the rut and then the smoothing blade will level or smooth the entire sur-lt'acecovered by the dresser. The runners 1 and 2 which are extended at their rear end beyond the smoothing blade will opcrate to prevent the smoothing blade from tipping thus insuring an even-distribution of the road material.

" g The overlapping of the plane occupied by thegrader bladesinsures the filling oi the ruts or other low places from both sides 7 as the machine' passes along in one direction.

The'arrangement of the grader blades at an obliqueangle with a space between them and the runner onthe opposite side of the 7 machine avoids the collection of'road material such as would have a tendency to clog the machine .and increase the draft. .This arrangement of blades also prevents any material being forced out tothe sides of the 'machine and the formation of ridges along the sides of the road which are av great annoyance to thetravelinig public and detrimental to road maintenance.

A dresser constructed as herein shown and described has no acute angles presented to the material being dressed such as would operate to catch the material and carry it with the machine and as abovestated 1t wlll leave no ridges of dirt, rock or the like in it s path and will leave no lumps V therein. V

Various changes in the form, shape, proportion: and other zminor details of construetion may be made, without departing from the principleor sacrificing. any'pf the advantages of the claimed invention.

1. A road dressing machine comprising lateral spaced bars'having their forward ends cut away, a pair of bars having their ends positioned in the cut away. portion,

said bars having aligning cut away por tions, teeth positioned in the cut away portions, bolts extending through the bars for clamping the bars into close engagement withthe teeth and holding the teeth against movement, and leveling members operating at the rear of the bars. V r

2. A road dressing machine comprising lateral spaced bars, teeth supported atone of the ends of the machine, a scraping blade secured toone of the" side bars and extend- 1 ing at an oblique angle with respect thereto, a scraping blade secured to the opposite bar and arranged at an oblique angle with re spect thereto, the last mentioned blade extending beyond the inner end of the first j In testimony that I claim theiorelgoing as my own, I have hereto affixed my signature.
