To 'all 'whom'. it may concern:
Be it known t at I. EDWARD Gr. CARR, a citizen of the United States, and a resident of' Milwaukee, inthe county of Milwaukee and State ot lVisconsin. and i'ormerl a resident of Oakland` in the county of .f larneda and State of California, have invented certain new .and useiul, Improvements in Subgrade- Scrapers, of which the following isa specification. i
My invention is an improvement in subgrade-scrapers, and has for its object to provide mechanisml of the character specified adapted to run upon the header boards or forms an to cut away the surface of the grade, and wherein the eut-ting blades may e adjusted to any desired depth, and is provided for permitting the scraper to be turned without the necessit o removing it from the roadway.
n the drawings:
Figure 1 is a top plan proved scraper,
.'Fig. 2 is a rear view,
Fig. 3 is a. section on the line 3-3 ot Fi 1, looking in the direction of the arrows a( view of the imjacent to the line,
Fig. 4 is a partial rear view method of adjusting the frame,
Fig. @fis a diagrammatic view showing a modified arrangement of the blades.
1n the embodiment of the invention in Fi s. 1 to 5, the scraper comprises able rame 1 outline. and shafts Q journaled longitudinally oi" the trame at the opposite sides thereof, and outside of the frame. These shafts are journaled in bearings 4 on adjusting plates 5, which are supporte by the frame, when the "fted to be showing the show u trame is li turned, but, under other conditions. support theirame upon the shafts, and wheels journaled on the ends of the shafts. l wheels are adapted to run uponlthe header boards or forms 6 for the roadway, and the adjusting plates 5 permit the traine 1 to be raised or lowered, that is, to be adjusted vertically with respect to the header boards or forms 6*'.
, These adjusting plates 5 with the frame 1 at their inner ends by links 7, each link being pivoted at one end to the 11, 1918, Serial No. 202,257. Application ier reissue med May 8, 1919. lSerial No. 295,791.
the levers are connected i 153,144, med March 7, 1917. Renewed November other end to an adjusting plate, and the said plates are of angle material, as shown. The outer en of each plate is connected by a link 8 with an angular lug 9 on a lever 10, pivoted on the Itrame, and ,having a transverse. pin 11 which is adapted to engage with one of a series of openings in a quadrant`12 secured to the frame for holding the lever in adjusted position. It will be evident that by means o the frame 1 may be adjusted vertically with respect to the wheels 6 and their supports, via-the header boards or forms Gf. Scraper blades 13, 14 and 15 are supported from the trame depending below the same in inclined or undercutting posi'- tion, the blades 13 and 15 being arranged in pairs.
As shown in Fig. 1` the blades 13 are at the center of the frame, being arranged in inverted V-shape. The blades 14 are inclined inwardly from front to rear, and the rear end of each blade 14 is spaced apart from the rear end of the adjacent blade 13 to allow the scraper to pass material which has been displaced by the blades without and to prevent the displaced material from materially impedin'g the progress of the scraper. Each pair oi'. blades 15. is larranged in inverted V-.Jhape in front of the space between thc adjacent pair of; blades 1? and 14. The blades 13 are connected with a suitable supporting trame 1G of angle material, and each blade 14 is connected to a similar supporting frame 17, the frames 16 and 17 being connected with the main iframe 1. Each pair of' blades 15 is connected with a supporting -rame 18, the said frames 16, 17 and 18 being ot angle material, as shown more particularly in Fig. 2., each traine. having a portion secured to the -main frame and the other portion depending therefrom for the attachment of the blades.
Suitable draft apparatus, indicated at 19, is connected with the front of the raine by means of eyebolts 20, the said draft apparatus being chains, in the present instance, which may be attached to a suitable motor. A shoe 21 is arranged at the center of the frame l.v the said shoehaving a hub 2'2, into which engages the lower end ot a shaft` 23, the shoe being connected with the shaft 23 by a piu, as shown by Figs. 2 and 3 of that. drawings. his shaft 23 passes through a sleeve Q4 secured to the main frame and relafrarne and at its Aim tive movements between the` shaft 23 and the main frame 1 can be effected by means elbow levers 25. `ach of these levers l short arm, the .adjacent ends of a pair of channel bars 2 he channel bars and inspaced relaand a bushing 2T is arranged on the pivotally connected with the frame l at their d are pivotallyconnected at their upper ends to the levers 25 at the junctions of the an llar portions of said levers. bm an inspection of Fig. 2

When the levers into the p I is also evldent that the first eff Fig. 2 of the drawings, so no special means are required to hold the levers 25 in their positions. en the scra er is lifted and resting upon the shoe- 21, the scraper can be w1 remove all line established scraper blades, l scraper blades, one or more cuts, either or light, may be made to quickly, and accurately establish and finish nite grade with respect to the header or forms 6. The
material projecting above la by the lower edges of the boards header boards or forms 6l with te grade may be made- Instead of arranging the blades p manner shown in Fig. 1.they may be arranged in other ways, for example, as diagrammatically shown` in Fig. 6, wherein a 26 are arranged withV their channels outward and that, by adjusting they th heavy` a `defi- .itis moved forward.
