LAND 'LEVELER.

Application'filed April 25,

To aZZ whom it may concern Be it known that 1, James H. Gonnrr'r, a citizen of the United States, residing at Sololnonville in the county of Graham and State of Arizona, have invented certain newand useful Improvements in Land Leve lers, of which the following is a specification.

This invention relates to new and useful improvements in land levelers, and the primary object is to provide an improved device of this character which is so designed as to be reversed for use as a. land pressing device when desired. A further object of the invention resides in providing a blade which is revolubly mounted soas to be disposed foruse as'a lGVGlQ-l or presser at will. 7

Still another object of the invention re.- sides in providing'manual means for the actuation of the blade so to dispose'the same to various angles in operation.

With these and other objects in view my invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafterreferred to and more particularly pointed out: in the specification and claims. V In the accompanying drawing forming a part of this'app'licatiomf Figure lis'a perspective view of the device constructed in accordance with my invention; and r V Fig. 2 is a longitudinal section therethrough. 7 In describing the invention I shall refer to the drawing in which simila reference characters designate corresponding parts throughout the several views, and in which 5 designates a pair of side pieces or runners which are of considerable length and are braced and held together at their rear ends by means of transverse bracing bar 6 and are held together at their front ends by means of a pair of bracing bars or beamsfli, said bars being spaced .a. considerable distance above thesurfa-ce of the ground to be', held in its adjusted position by means of. the lever. 14:. and the bearing fmember 16: as clearly shown, and by dispo-sing the lever. to

[an upward position the 'bladef ma j 'tirely revolve 1 so as to form a land and "when in. this position the'b-lade will leveled. Mounted on the bar 7 isastand boa d 8 whereby the operator of the device may apply lflsweightto the leveler. h

Qecured tothe inner and outerfacesof the runners or side p ieces'b are the angular metal bearing plates 9. and revolubly mounted in the side pieces and in the bearing. lates is a shaft 10 which is held inpla'ce in any preferred manner. Secured to the'revoluble shaft 10 is an arcuate blade 11 which 1921. Serial No. 464,282.

has both edges thereof beveled to form cutting or'engaging edges, as clearly shown at.

12. In the particular position of the blade as shown in Figs. 1 and 2 of the drawing the concaved face of said blade fa-ces forwardly when the device 1sbe1ng used as a" leveler,

and when the shaft 10 is revolved to dispose The metal bearing plates 9' project up' i wardly against the upper edge of the runners or side pieces 5, and revolubly mounted therein 'is an additional shaft 13. Re-

movably bolted to the shaft 13 is a lever 14,

tact with the face of the blade 11, as clearly shown in Figg2lof the drawing. A handle l5'is provided on the lever to actuate the same and an additional bearingmember 16 the lower end of which isadap-ted to eon-l isremovably secured to the shaft 13 which stand-board 8 and a spring'detent 18 car- V .ried'on-the lever 14c is adapted to engages-aid rack so as to retain the lever and correspondsingly theblade'in any adjusted position.)

The blade may befadjusted to the desired angle so as to properly'dischargethe load. 7

The-blade will be .joresser 1 which will elimi- From the foregoing description of the construction of my improved device, the operation thereof will be readily understood, and it will be seen that I have provided a simple,

inexpensive and efficient means for carrying out the objects of the invention.

While I have particularly described the elements best adapted to perform the functions set forth, it is ob ious that various changes in the form, proportion and in the minor details of construction may be resorted to without depar -..g from the spirit or sacrificing any of the principles of the invention.

hat I claim is:

1. A device of the character described including a pair of ground engaging parallel side runners, a shaft extending transversely of the runners, a blade secured to the shaft and adapted to have either of its longitudinal edges disposed in contact with the ground, said blade when in one of said positions forming with the runners aload carrying receptacle in front of the blade and means for retaining the blade in contacting relation to the ground when in either of said positions.

2. A land leveler comprising side runners spaced apart, a blade revolubly mounted between the runners and forming with the runners in front of the blade a load carrying receptacle, a lever fulcrumed on said runners, and having its one end in frictional contact With said blade to actuate the same to various positions, and means for locking said lever in various adjusted positions.

3. A land leveler comprising side runners, a blade revolubly mounted between them and forming with the runners load carrying receptacle in front of the blade, said blade being capable of use as a scoop blade in one position and as a pressing device when disposed to another position, a lever fulcrumed on said frame and having its oneend in frictional engagement with said blade, and means for locking said lever in its various adjusted positions.

l. A land leveler comprising long side runners, a blade revolubly mounted between them, and forming with the runners a load car 'ying receptacle, said blade being capable of use as a scoop blade when disposed in one position and adapted for use as a pressing device when disposed in another position, a lever fulcrumed on said frame in a plane above said blade and having its lower end adapted for frictional engagement with said blade to retain the latter in its adjusted positions, and means for locking said lever in its adjusted positions. I

5. A land leveler comprising side runners, a blade revolubly mounted between them, forming a receptacle in front of the blade, a shaft rotatably mounted on said franiie in a plane above the horizontal plane of the axis of said blade, a lever removably secured to said shaft and having one end hereof adapted for frictional contact with said blade above itsrevoluble axis, a bearing member carried on said shaft adapted for contact with said blade, and means for locking said lever in its Various adjusted positions.

6. A land leveler comprising side runners, an arcuate transverse blade revolnbly mounted between them, intermediate their ends.

3 thereon, said blade being adapted for use as a scoop blade when disposed in one position and adapted for use as a pressing device when revolved to another position, a shaft rotatably mounted in said frame in a plane above the horizontal plane of the axis of said blade, a lever removably secured intermediate of its ends on said shaf and having its lower and adapted for frictional contact with said blade to limit the movement of the latter in one direction, a bearing member removably carried on said shaft and adapted also to contact with said blade, and means for locking the said lever and correspond ingly said blade in various adjusted positions.

In testimony whereof I afiiz: my signature.
