PLOW.

SPECIFICATION forming part of Letters Patent No. 470,913, dated March 15, 1892.

Application tiled September 30, 1891. Serial No. 407,238. (No model.)

To all whom t may concern,.-

Be it known that I, Louis S. FLATAU, of Pittsburg, in the county of Camp and State of Texas, have invented a certain new and useful Improvement in Plows; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to that class of plows in which some sort of mold-board, share, or point and landside are used in combination, and has for its main objects to provide for use a plow of this type in which the combined parts shall be extremely simple in their forms and adaptation to each other, and hence economical of manufacture, and in which, also, the usual rapid wearing away of the rear outer and lowermost portion of the landside (usually designated the heel of the plow) may be easily and efficiently compensated for by simply shifting or reversing the position in several ways of the steel bar which constitutes the landside proper of the plow, all in a manner which will be hereinafter more fully explained. All such plows Athat I know of have been constructed so that there has been more or less steel wasted in the landside and with a greater or a less number of offsets or joints requiring' to be fitted, so that the plow, both as to its cost of manufacture and on the score of durability, has been unnecessarily expensive.

In my improved plow of the species or type alluded to the implement is exceedingly simple and economic of manufacture, while at the same time the plow is very durable and lperfectly efficient in operation, and,furthermore, the usual wearing away of the heel may be compensated for by a utilization of allv four corners, so to speak, of the simple rectangular-shaped landside, which may be made of very hard and durable material without undue expense, and which may be easily removed and shifted or adjusted for use in different positions by any one comparatively unskilled in mechanical labor.

To enable those skilled in the art to make `and use plows containing either in part or in whole the improvements made the subject of this application, I will now proceed tof more fully describe my invention, referring by letters of reference to the accompanying drawings, which form part of this specification, and in which I have illustrated my invention carried into effect in precisely the forms in which I have so far successfully practiced it, although my said invention may of course be carried out Linder various modifications thereof.

In the drawings, Figure l is a side elevation of so much of a plow as it is necessary to show in order to fully illustrate my invention, looking toward the landside of the implement. Fig. 2 is a bottom view of the parts seen in elevation at Fig. l. Fig. 3 is a top view of the same, but with the moldboard detached or removed. Fig. 4. is aback View or elevation of all the parts seen in Figs. l and 2. Fig. 5 is a detail section at the line x .r of Fig. l.

A is the frog, which, as shown, is formed with an integral rearward bar-like extension a, the rearm'ost end of which is about vertical and lies in about the same plane as the extreme rear end of the landside proper, which landside, as clearly shown, is composed of a simple steel bar D, which is preferably made of about the size and shape in cross-section illustrated.

B is a share, which is securely fastened to the frog A by means of two bolts or rivets, one of which c enters the wing-like or nearly horizontal portion of the frog A, while the other d enters the vertical portion of said frog near its forward end.

C is the mold-board, which at its lowermost portion is securely bolted or otherwise fastened, as seen, to the wing-like portion of the frog A by suitable securing devices e e.

The hardened-steel landside proper D is secured. to the landside portion or bar-like extension a of the frog A by means of two or more bolts f f, which, projecting inwardly from the said landside D, pass through perforations in the frog a and are provided, as shown, with nuts e z', by means of which thel said landside D and frog-extension a are securely, but detachably, connected.

Preferably the landside steel bar D is made of about the same thickness as the bar-like extension a of the frame,but is of a height of IOO one-half or a little more than one-half of that of the said bar-like extension, and the securing-bolts f f must be arranged each at the same distance from the adjacent end of the landside D, so that said landside may be turned end for end and the said bolts always match or register with the perforations in the bar-like extension a of the frog.

Of course the sizes and proportions of the several parts so far described, as well as the relative sizes of the share or point and the mold-board of the plow, may be varied more or less as may be deemed expedient.

The share-bar or point-bar is of the same thickness, it will be observed, (see Fig. 2,) as the landside D, and the rearmost portion or edge of said bar lies in a line at right angles to the base-line of the combined share and landside, so that a simple butt-joint in a vertical plane is formed between the forward end of the landside D and the rear end of the share-bar. Hence if the landside D be reversed in position, so as to bring its rear end t0 the place occupied by its forward end, the said rear end will make the saine perfect buttjoint with the rear end of the share-bar as is made by the present relationship between the two parts mentioned.

It will be observed that the frog A, with its bar-like extension, comprises, simply, a vertical and horizontal portion, 011 which latter rests and are supported the share and the lower portion of the mold-board, and that the vertical portion of the frog extending well forward beyond the butt-joint between the share-bar and the forward end of the landside D, all as shown, an exceedingly simple and at the same time a strong and durable union is effected between the share, the landside, and the frog of the plow.

It will be observed that the frog or, so to speak, metallic frame to which are secured and which carries the share, the landside, and the lower portion of the mold-board has no offsets or intricate conformations of any sort, so that it is easy and economic of manufacture, while at the same time the share, the landsi'de, and the frog or frame 0f the plow all go together in a simple manner and yet so as to properly reinforce each other and render the combined structure exceedingly strong and durable.

In the use of my improved implement whenever the lower outer and rearmost portion of the landside D shall have become materially worn, so as so affect the perfect working of the plow, the implement may be restored to a perfect working condition by simply loosening and removing the nuts it', turning or shifting the landside D end for end, and then reseeuring it in place by the said nuts, all in a manner which will be easily understood and that can be practiced by the most inexperienced user of agricultural impleinents.

As will be observed by reference to Fig. 5, each of the perforations in the landside D is counter-sunk at the opposite surface of the bar, so that countersunk heads of the bolts f fwill fit fiush into either surface of the bar, and by means of this known expedient I am enabled, it will be seen,not only to turn the bar or the landside D end for end, as above explained, to bring the fresh corner or edge of the bar at the locality of the heel ot' the landside, but can also turn the bar inside out, so to speak, or reverse it with either of its ends at the heel portion of the plow, and by thus reversing the bar D it will be seen I bring to the lower edge what was the fresh and unworn upper edge of the rear portion of said bar. Hence by this easy shifting or adjusting of the landside D,Iam enabled with the use of the simple steel bar which constitutes the landside to produce four separate or new portions at the locality of the greatest or most rapid wear of the landside and at the same time maintain a perfect or the original base-line practically of the entire landside and share-bar.

It will be understood, of course, that that part or feature of my invention which relates to the novel form of frog or frame combined with a share, landside, and mold-bar sustained thereby may be used separately from or independently of the other features or part-s of my invention, which relates solely to the simple and economie manufacture of the landside proper and its combination with the supporting-frog or its bar-like extension in such manner as to permit of the various and easy changes by which the worn-away heel of the plow may be frequently renewed, and that therefore I wish it to be understood that I design my claim to cover separately these separable combinations or features 0f invention, although I deem it preferable and desirable in carrying my invention into effeet to make the plow so as to embrace both 0f them.

Having now so fully explained my invention that those skilled in the art can make and use plows containing either in whole or in part my said improvements, either in the precise forms herein set forth or under some modifications thereof, what I claim as new, and desire to secure by Letters Patent, is-

In combination with the share or point of the plow and the supporting or sustaining frog A, lformed or provided with a rearward bar-like extension and having no offsets or projections, the reversible laudside D, each end of which is adapted when variously adjusted to make a perfect butt-joint with the rear edge of the said share or point bar, all substantially in the manner and for the purposes hereinbefore set forth.

In witness whereof I have hereunto set my hand this 27th day of July, 1891.

LOUIS S. FLATAU.
