UNITED STATES PATENT orrioa I EDWARD B. JAMES, OF CORDELE, GEORGIA.

PLOW.

To all whom it may concern Be it known that I, EDWARD B. JAMES, a citizen of'the United States, residing at Cordele, in the county of Crisp and State of Georgia, have inventeda new and; useful Plow, of which therfollowing 1s a spec fica' tion.

. This'invention relates to plows, and has for its object to provide afnovelfrog and adjustable connection of the standard of the frog with the plow beam. 7 With the above, object in view this invention is embodied in the novel construction and arrangement of parts as hereinafter described and asillustrated in the accompany ing drawings, wherein similar reference characters indicate similar parts, and wherein,-

Figure 1 is a perspective view of a plow constructed in accordance with the invention, with parts broken away and parts shown in dotted line. Fig. 2 is an elevation of the frog. Fig. 3 is a perspective view of a detail. Fig. i is a section taken through the upper end of the standard, illustrating the means for adjusting the plow beam. Fig. 5 is a front view of a modified form of frog.

Referring specifically to the drawing, the frog comprises the shoe 13 and'the pallet or resting plate 14, and has an integral standard 6. The forward side of the standard is gently curved forwardly with its upper end overhanging the tip or point of the frog. The lower ortion of the standard is solid and merges 1nto the corner of the frog, while the upper portion of the standard is enthe rear portion larged and is U-shaped in cross section with the opening disclosed rearwardly so as to provide checks 7 The cheeks 7 are widened and have arcuate slots 17 adjacent their upper ends. A handle engaging memberjll projects upwardly in an inclined position from'the rear end'of the shoe 13, and is connected to the solid or lower portion of the standard by the integral handles 20 are attached to the portion 11 by bolts or other securing members, it being noted that in this manner, the handles are rigidly connected to the standard as well as to the frog proper.

The plow beam which has been denoted by the numeral 5, is constructed of an I-beam, of the beam being curved downwardly gently on an arc corresponding with the arc of the standard. The rear end of the standard is snugly housed between the adjusted or portion 12. The

cheeks 7 if of the standard,the flanges of the beam contactingewith the cheeks, The bolt 10 passes through the lower ends of the cheeks andthrough the web of the beam so .as tofulcrum the beam and standard to. 'gether,

and a bolt 9 passes loosely through the slots 17 and through position,

ries of small circular indentures or notches 18 in its outer side beyond each end of the slot 17,'and the corresponding washer is provided with a small circular spur 16 adjacent one end, this washer being rotatable on the bolt when the bolt is loosened so that the spur may be engaged with either series of indentures according to the adjustment of the standard and beam relative to each other. It will be noted that the washers 8 bear against the outer-sides of the cheeks, the adjoining faces of the cheeks and washers being fiat or smooth with the exception of the indentures or notches as above-indicated. The washers also cover theslots, as is desirable.

With this construction and combination of parts as above described, it will be noted that a desirable, simple, compact and efficient plow structure is provided, and one which permits of the ready and efiective adjustment of the frog and beam relative to each other. To adjust a frog and beam relathe web of the beam, to clamp the cheeksagainst theflanges of the beam. In order to lock the bolt 9 in. after it has been tightened, anelon gated washer 8 has been mounted on each end of the bolt. One of the cheeks has a setive to each other, thebolt 9 is loosened, to I relieve the cheeks from the flanges of the beam, and to loosen the washers from the cheeks, the spur being disengaged from the corresponding indenture or notch. After the standard and beam have been properly swung relative to each other, theymay be so locked by first swinging the proper washer 8 in one position or theother so that the spur may engage the proper series of indentures 18, and then tightening the bolt 9 so as to first clamp the washers against the cheeks and then to clamp the cheeks against the beam. The washers in beino: clamped against the cheeks will cause the spur to be locked in engagement with the respective indenture, and as aresult, the bolt 8 and the beam 5 will relative to the standard.

Attention is directed to the fact that the distance between the bolt 9 and the spur 16 belocked in position is less than half the distance between the two series of indentures 18, whereby when the washer 8 having the spur 16, is rotated to permit the spur to engage the respective series of indentures, a relatively large amount of adjustment between the beam and frog may be had. Thus, when the spur 16 is engaged in one series of indentures 18, as seen in Fig. l, the frog will be swung downwardly and rearwardly, while when the spur 16 is engaged in the other or forward series of indentures 18, the frog will be swung forwardly and upwardly slightly.

In the form shown inFig. 5 the frog is provided with a pair of pallets 19 on the respective sides thereof, this construction of frog being adaptedv for the middle burster or list-er type of plow. The standard 6 is identical with the standard of the former frog, whereby the frogs may be made inter changeable with the plow beam to adapt the same for either the middle burster .plowor a turn plow.

What is claimed is In a plow, a frog provided with a standard, of U-shaped cross section, a plow beam washer having a single small circular spur,

adjacent one end thereof the distance between the bolt and spur being less than half the distance between the tures, and the said washer :when the bolt is loosened, in order that the 5 spur may engage either series of indentures.

two series of indenbeing rotatable In testimony that I claim the foregoing as my own, I have hereto afiixed my smgature 'in'the presence of two witnesses.
