SCRAPER AND SHOVEL-PLOW.

SPECIFICATION forming part of Letters Patent NO. 772,367, dated October 1.8, 1904.

Application led August 24:, 1903.

To all whom. t may concern.-

Be it known that I, NEAL MCLAUGHLIN, a citizen of the United States, residing at Jethro, in the county of Franklin and State of Arkansas, have invented new and useful Improvements in a Combined Scraper and Dir-ter, of which the following is a speciiication.

My invention relates to improvements in combined scraper and shovel-plow,l and pertains more particularly to that class used in the cultivation of cotton.

The object of my invention is to provide a reversible scraper which in either of its positions can be readily horizontally or vertically adjusted and also adapted to be adjusted at an angle, the one holding means serving to hold the scraper in any and all of the adjusted or reversed positions.

Another object of my invention is to provide a scraper of this character in which the shovel-plow is correspondingly vertically adjustable and also adapted to be adjusted at any desired angle.

In the accompanying drawings, Figure l is a perspective view of my improved combined scraper and shovelplow. Fig. 2 is an enlarged perspective view of my improved scraper removed. Fig. 3 is a transverse hori- Zontal sectional view of Fig. l. Fig. .tis a vertical sectional view, partly broken away, of Fig. l. Fig. 5 is a perspective view of the holding-plate.

Referring now to the drawings, A represents the draft-beam of my improved ma-v chine and which is provided at its outer end with the ordinary clevis B, by meansof which the scraper is drawn along. The said draftbeam is formed of two fiat bars C and C', which are welded together at their forward end, and passing through the said beams C and C adjacent the rear end is a bolt D, which extends a slight distance beyond the beams and has secured thereto the upwardly-extending handles E and E', which have the downwardly-extending braces e and e', which are secured to the bars C and C@ rl`he rear end of the beam C is curved downwardly in the arc of a circle at c and is provided adjacent its lower end with two openings F and F', which extend horizontally th erethrough and by means of which the scraper Serial No. 170,603. (No model.)

is secured thereon, as hereinafter more fully described. The scraper G consists of a rectangular piece of sheet metal, which is preferably of an elongated form and in cross-section is also curved in an arc of a circle to correspond With thel curved` portion of the bar C. The scraper, as before stated, is of rectangular form, having its two diagonal opposite corners obtuse anglesand the other two diagonal opposite' corners acute angles. Thus it will be seen that the lower edge is in a horizontal plane as the said scraper extends in a line oblique to the plow beam. The said scraper adjacent each end is provided with two openings H and H', which are arranged in a verticalV plane one above the other, and above and below said openings are segmental slots /L and z. The bar C being flat on its forward face it is necessary to hold the scraper thereon at an angle, and thus I provide a member J. The said member J is curved to correspond with the curvature of the lower end o of the member C and is provided with the verticalelongated slots j and j', and the edge thereof is provided with a laterally-extending flange f2, which is also' of a curved form ycorresponding to that of the curve of the scraper G. f Y

The member J rests against the forward edge of the curved portion of the bar C, with the iiange J on the outside, and the scraper is then placed thereon and is adapted to bear against the ange J and the opposite edge f2 of said member. The bolt K3 passes through the lower opening H in the scraper, through the lowerl elongated slot j", and through the lower opening F in the member c. A second bolt passes through the upper segmental slot L, through the slot j' in the plate J and through the upper opening in the member o. Thus it will be seen that when the nuts K on the ends of the bolts are drawn tight the said scraper is clamped to the member C at an angle to the iiange J rIhe upper bolt` K2 being in the segmental opening, it will be readily seen that by loosening said bolts the lower bolt serves as a pivot for the scraper,. and it is adapted to be turned thereon at any angle, and the upper bolt is then tightened, and it is held firmly in its adjusted position. When it is desired to raise the scraper, the

lower bolt K3 is passed through the lower segmental slot L, and the upper bolt passes through the upper opening H of the pair, and it will be clearly seen that the adjustment is precisely the same. Having the two series of openings, one at each end, allows of the reversal of the scraper when one end has become worn, and it also allows of the precise arrangement and adjustment, as both ends are constructed precisely alike. This construction also allows of the scraper being placed to either side of the bar C.

The bar C' extends considerably Jfarther backward than the bar C and is turned downwardly at c in a manner precisely like the bar C and has an opening L extending therethrough. The shovel-plow M consists of a vertical plate having a vertical elongated slot m therein, through which passes the clamping-bolt N and by means or' which the said shovel-plow M is vertically and obliquely adjusted on the bar C@ The said vertical portion of the scraper is provided with an obliquely-arranged upwardly-extendingscraper proper,O.

The operation or' my device is as follows: The scraper is lirst adjusted in its proper position, and the shovel-plow is adjusted accordingly-that is, it is adjusted in about a hori- The scraper being in advance of the shovel-plow it will' thoroughly scrape all the grass, weeds, and lumps of dirt away from the cotton, and the shovelplow being at an angle exactly opposite to the scraper it will throw the ne dirt up around the cotton.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A scraper comprising a draft-beam, a downwardly extending curved member, a blade having a vertical movement on a fulcrum-point which is adapted to allow the free end of the blade to be swung up or down.

2. A scraper, comprising a draft-beam having a downwardly-extending member, a blade having| two openings one above the other, segmental slots above and below the said openings, and bolts passing through one of said openings and one of said slots.

3. A scraper, comprising a draft-beam, a downwardly extending curved member, a curved rectangular blade having two openings one above the other, segmental slots above and below the said openings, and bolts passing through one of said openings and slots and through the downwardly-curved member.

LA scraper, comprising a draft-beam, a downwardly-curved member, a curved angular-shaped plate resting against the forward part of said curved member, a curved rectangular blade resting against said curved angular-shaped plate and having two openings one above the other, segmental slots above and below said openings, and bolts passing through one of said openings and slots, and through the wedge-shaped block and the downwardlycurved member.

5. A scraper comprising a draft-beam, divided adjacent its rear end, one end or' said divided portion turned downwardly, a reversible and adjustable blade carried by said downwardly-extending member, the other end of said divided portion of the beam extending rearward and turned downwardly and an adjustable shovel-plow carried by said downwardly-turned member.

6. A scraper comprising a draft-beam, a downwardly extending curved member, a curved plate resting against said downwardlyextending member, and having an elongated slot therein, an outwardly-extending ange carried by said plate and having a curved edge, a curved rectangular blade resting against said flange and plate, said blade having adjacent each two openings one above the other and segmental slots above and below said openings at each end of the blade, a bolt passing through one of said openings, and a second bolt passing through the segmental slot in the blade and said bolts passing through the slots in the plate and through the curved member.

7. A scraper, comprising a draft-beam, a downwardly-extending curved member, carried by the beam, a curved angle-plate resting against said curved member, and having elongated vertically-disposed slots therein, a blade resting against said plate, and bolts passing through said blade, the slots in the curved angular plate, and the downwardly-extending curved member.

8. A scrapercomprising a draft-beam, a downwardly-curved member carried thereby, a curved angular plate resting against said curved member and having elongated vertical slots therein, ablade resting against said plate and having openings and segmental slots so arranged that the blade may be vertically adjusted together with the plate, or may. be swung on said plate.

9. A scraper, comprising a draft-beam, a downwardly-curved member carried thereby, a curved angular plate resting against said curved member, and vertically adjustable thereon, a blade carried by said plate and means for oscillating said. blade on said plate.

lO. A scraper, comprising a draft-beam, a downwardly-curved member carried thereby, a curved angular plate resting against said curved member, a blade resting against said curved plate, and means for vertically adjustably holding said blade on said curved member and said means constructed to allow of an ,oscillating movement of said blade.

In testimony whereof I have hereunto set my hand in the'presence of two subscribing witnesses.
