FRED A. GARVIN, OF WASHINGTON, DISTRICT (IF COLUMBIA.

STONE-RAKE.

Application filed August 26, 1916.

To all whom it may concern:

Be it known that I, FRED A. GAnVIN, a citizen of the United States, residing at Washington, District of Columbia, have invented certain new and useful. Improvements in Stone-Rakes; and I do hereby declare the following to be at full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in a stone rake and one of its objects is the provision of a device of this character, which shall be simple, durable and efficient, and which may be manufactured and sold at a comparatively low cost.

Another object of this invention is to pro vide a frame mounted on a pair of wheels and having a plurality of plows thereon for digging up stones embedded 1n the surface of the ground.

A further object of this invention is to provide endless conveyers cooperating with the plows to receive the stones dug up and the ones collected from the surface of the round for carrying them to a stone collect mg receptacle located upon the frame, whereby stones may be readily collected and deposited at a desired place.

A still further object of this invention is to provide means for raising the plows from an engagement with the ground when the stone receptacle has been filled, so that the device may be rendered inoperative to prevent overloading of the receptacle.

With these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of mv invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a top plan view of a stone rake, constructed in accordance with my invention,

Fig. 2 is a longitudinal sectional view of the same,

. Fig. 3 is a detail view partly in section of the stone collecting receptacle,

Specification of Letters Patent.

Patented Apr. 17, 1917.

Serial No. 11' 3098.

Fig. 4 is a de1ail elevation of the means for raising and hwering the plow, and I Fig. 5 is a (let ail sectional View taken on the line 55 of Fig. 1.

Referring in detail to the drawings, the numeral 1 IlIldlCttGS a substantially rectangular frame having secured adjacent the rear end thereof an axle 2having each end reduced to form. spindles 3 on which are journaled squared sleeves 4. The squared sleeves 1 have fc rmed upon their inner ends gears 5 and also have secured thereon ground wheels 6 for supporting the frame 1. The frame 1 hits secured thereto vertical standards 7 to which are secured upwardly inclined handles 8 which have their lower forward ends s :cured t0 the frame. The standards and handles are connected together by a trar sverse bar 9.

A conveyer supporting member consisting of a plurality 01 parallel extending bars 10 are secured togel her by a transverse strip 11 and the outer he: 's of the series are of reater width than the remaining bars to cm a trough-like construction and each of the bars 10 is pivovally secured to bracket 12 carried by the a: :le 2. The forward ends of the bars 10 are reduced and inclined downwardly to form plow points 13 which are connected togetl er in V-shaped formation as clearly illustrated in Fig. 1. A transverse shaft 14: is j ourr aled in the bars 10 adjacent the plow points 13 and has mounted thereon gears 15 which rotatably support endless conveyers 16. The endless conveyers 16 are in turn mounted upon enlarged gears 17 carried by a drive shaft 18 which is journaled within the frame 1 at a point rear of the axle 2 and has. mounted on each end gears 19 that mesh with the gears 5 for rotating the conveyers 16, so that when stones are dug up by the plow points 13 they are caught by the conveyer; 16 and carried rearwardly.

A stone collecting receptacle 20 constructed from a plurality of interwoven wires is provided with supporting arms 21 on each end thereof for overlying a portion of the rear end of the frame 1 adjacent the enlarged gears 17 so that the stones that are carried rearwardly by the conveyers may fall into the st me collectin receptacle 20. A rack 22 is serured to the rame 1 and has pivoted thereto a lever 23 having the usual hand grip 24 for operating the dog 25 which engages the teeth of the rack 22. An arm 26 is formed on the lever 23 and is pivotally secured to the forward end of the conveyer supporting construction, whereby upon op erating the lever 23, the plow points 13 may be caused to engage and disengage the ground.

In operation, draft animals are fixed to the forward end of the frame 1 in any suitable manner and by pushing the lever 23 forwardly, the plow points 13 will be lowered into an engagement with the ground. Upon forward movement of the device, the plow points will dig into the ground and dig up any stones that may be embedded in the ground near the surface thereof, causing the stones to pass upwardly over the plow points on to the conveyers 16 thence they travel rearwardly into the stone collecting receptacle 20. After the stone collecting receptacle 20 has been filled, the lever 23 may be drawn rearwardly raising the plow points from an engagement with the ground thus rendering the device inoperative to prevent overloading of the stone collecting receptacle. The device then may be driven to a convenient place and the stone collecting receptacle 20 removed from the frame and emptied. If not desiring to pull the device to a desired place, the stone collecting receptacle 20 may be removed from the frame copies 01' this patent may be obtained for and emptied into a wagon or cart which may be brought adjacent thereto for carrying away the stones to a given point.

While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.

Having thus described my I claim is A stone rake comprising a frame, an axle secured to said frame, wheels carried by said axle, a conveyer rack pivoted to said axleand consisting of a plurality of parallel bars having their forward ends reduced and connected together in'V-shaped formation to form plow points, a transverse strip connecting said bars together, an endless conveyer mounted on said rack for receiving stones from the plow points, and a stone invention, what collecting receptacle carried by the rear end of the frame to receive the stones from the conveyers.

In testimony whereof I aflix my signature in presence of two witnesses.

FRED A. GARVIN.
