PLOW.

SPECIFICATION forming part of Letters Patent No. 374,565, dated December 6', 1887'.

Application filed April 25, 1887. Serial No. 236,248. No model.)

ing had therein to thev accompanying draw-- ings.

This invention pertains to certain new and useful improvements in plows; and it consists 1n the detailed construction, combination, and

arrangement of the parts, substantially as hereinafter fully set forth, and particularly 'pointed out in the claims.

In the accompanying drawings, Figure 1 is a View in side elevation of my invention,with

-. one of the side plates of the landside removed.

Fig. 2 is a rear view thereof. Figs. 3 and 4 are enlarged detail views of the two-part crotch and retaining mechanism. Fig. 5is an enlargeddetailplan view ofthe clevis,embody ing a modification thereof. Fig. .6 is a view of a modification of my crotch. Fig. 7 is a cross sectional view on the line x x, Fig. l.

t Fig. Sis another' enlarged view of the crotch.

Fig. 9 is a detail view showing the pivotal bearing for the plow-point, and Fig. 10 is a detail view of thejointer-plate.

The object of this invention is to provide a plow whereby the mold-board and the plowpoint, together with the jointer, may be used for either a right or left hand plow, according to the side of the landside and the shoe on which the mold-board is placed, and to provide a crotch of peculiar formation which can be pivotally secured on the same rod asthe plow-point head, and by means of which the mold-board can be held at the same relative position on either side of the landside, notwithstanding the fact that the pivotal bearing of the crotch is not on the same horizontal plane with the plow-point or head.

In the organization of my invention I provide a forwardly-projecting plow-beam, A, which at its rear endis curved into a vertical portion, a, the lower end of which is again curved and projected forwardly in under the beam A, forming a slice, c. To the forward end of this vshoe is secured (or it may be integral therewith) the lower end of a vertical bar, a, of an inclined frame, b, the rear vertical bar, a2, thereof being. secured on the upper portion of the shoe near its rear end.

B is a hollow tube or rod passed on an ineline through an aperture in the lower end of the vertical portion a of the beam and extending through a similar aperture in the bar a2 of the frame b, from which point'it is narrowed, and is extended over the upper surface of the shoe and through the forward vertical bar, a, of said framing. The projecting endof said rod has a small collar iitted thereon, the purpose of which will appear farther on.

Ois the reversible mold-board,to the forward which and the end of the mo1d-board is fitted a plow-point, b. The under or outer side of this plow-point head b is so formed that when the under side thereof is, together with the plow-point, penetrating the earth, the other correspondingly-shaped side is in a vertical position, which serves as a landside, in connection with the shoe a and the landside proper, which consists of .a metallic plate, a3, secured on either side of the frame b, one of .6 5 end of which is connected by suitable means the rear vertical wall of a hollow head, b',over

which plates being shown in Fig. 1. If desired, the frame and landside-plates can loe made integral, and also the shoe of the beam. The projecting end of the tube or rod B, above referred to, is passed through an aperture formed in the rear wall of the plow-point head b', after which the collar is secured on said end of rod, so as to retain the same in position. This tube or rod forms the pivotal bearing for the plow-point head, the point proper, and the mold-board, all of said parts being rigidly secured to each other. j

As heretofore constructed, reversible plows board is attached pivotally secured at the lower heel end of the plow-beam, which must of necessity be on the same horizontal plane.

usually have the crotch to which the moldits inner surface removed for fitting a twoarmed V-shaped part or member, d, which is pivoted at its lower convergent end to thelong arm or member d, and its projecting arms are rigidly secured to the under side ofthe moldboard. The part or member d is of approximately V shape, having its ends slightly extended and its upper central portion curved, as shown. The upper end of the long arm` or member projects slightly above this curved portion, and has a finger or pivot, e, rigidly secured to said end and projecting over Vsaid curved portion, and entering or working in a slot, e', formed in one end of asliding arm or bar, E, which is pivoted near said end to the center of the V-shapedpart or member f1', near the upper curved portion thereof. This sliding arm or bar E has a groove, e, formed in its front face, terminating in a small aperture or recess, e2, at its other end. In this groove e of the sliding arm projects a stationary finger, f, through the center of which is passed a sliding or movable finger, f', the forward end of which is widened, as atf, and has agroove or socket formed in its under surface for reccption of a curved or ball-like end, g, of a lever, G. This lever is fulcrumed on a small rod bearing at its ends in apertures formed in corresponding projecting cheeks or plates g of the frame b,as shown in Fig. 1, and to the upper shorter arm of this lever is secured one end of a spring, g", which bears against the rear bar of said frame, as shown in Fig. 3.

To the rear end of the tube or rod B is rigidly secured a toothed cam, h, with which engages thelower widened toothedend of alever, H, fulcrumed on the rear side of t-he vertical portion a of the plow-beam on a horizontallydisposed rod, L. This lever is provided with a'retaining-pawl, h', which engages with a segmental rack, h, bolted to the upper rear end of the plow-beam, and said pawl is fitted to slide in apertured lugs projecting from one side of the lever H, and to said pawl is applied a spring, h", arranged between said lugs to automatically hold it in engagement with said rack h. In order to eect the disengagement of the pawl from its said rack as the lever H is grasped for manipulation it is connected by a rod, i, to a supplementary lever, i', pivoted to the leverH, and to this rod or wire is rigidly secured a small rod or finger, i2, passed through and working in a slot in the lever H. To the i out-er end of this rod or finger is connected one end of a rod, J, passed through eyes on the rear side of the lever H and down to and through the central aperture in the tube or rod B, from which it passes at j, and is connected to the lower end of the lever G, to which end is also connected a small thin rod, j', projecting at its thickened forward dog-like end through an aperture in the front vertical bar of the frame b, where it is designed to enter slots 0r apertures formed in the rear of the plow-point head for securing the same together with the plow-point and mold-board on either side of the shoe or landside.

To the forward end of the plow-beam is connected the self-adjusting clevis K, which consists of a pivoted post, k, secured between apertured horizontal plates on the forward end of the plow-beam and an approximately oblong bar or plate, k', having projecting apertured ears, through which and a corresponding aperture in the post k is passed an ordinary securing-pin. The bar or plate k has an aperture, k, extending its full length, and in this aperture works the rear frame-like end of a.

.hook, la, having a vertically-disposed frictional roll bearing against the innersurface of the bar, and to this hook is connected, in practice, the whifetree of the horses harness. Suitable stops, ZZ, aredisposed in the aperture k", for regulating the extent of the lateral movement of the hook, said stops being retained at the desired point by means of set-screws.

To the lower end ofthe pivoted post is secured a preferably looped crank or cam, l', projecting rearward, and into said loop projects the forward downwardly-bent end of the horizontally -disposed wire rod L, which is passed through eyelets on the under side of the plow-beam, and after being passed through an aperture in the rcar portion of said plowbeam is rigidly secured to and forms the fulcrum-for the lever H.

The object of providing the bar or plate of the clevis with an aperture wherein the hook slides isl to permit the clevis to automatically adjust itself to the rightand left of the center of the beam, thus throwing theline of draft to either side of said beam,whereby the desired amount of draft to or from the land is obtained, so that when the mold-board and plow-point are reversed the clevis will be automatically adjusted through the agency of the pivoted post, causing the hook to slide to and abut againstthe opposite stop to that against which it was formerly bearing, said stops having inclined sides'to correspond with the sides of the frame of the hook, as shown.

It will be seen in Fig. 5 that I have connected a small hand-lever, m,to the upper projecting end of the apertured post 7c, so as to permit the clevis to be used on a hand-plow, the construction herein described being intended, preferably, for a sulky-plow.

N is the reversible diamond-shaped jointer, symmetrical on both sides of its center line, and is secured at its center by an ordinary bolt to a thickened plate, n, fast to the lower forward end of a shaft or rod, n', which is passed into a slightly larger tube or cylinder, n,whereiu it is retained by means of asetscrew, n", as will appear farther on. The thickened plate n has an upwardly-projecting apertured arm, o, through which is passed a bolt, o', also passed through an aperture in the corresponding part of the jointer for the more secure retention thereof.

The object of making the jointer diamondshaped is, that when one point has become uscless by reason of wear,by removing the bolt o',

Io L.

the jointer-points can be reversed by turning the same on its central pivotal bolt, after which the rear point is also secured by means of the bolt o.

rlfhe tube or cylinder a, above referred to, is passed through an aperture in or adjoining the vertex of an approximately Vshaped frame, P,- secured at its ends to the plow-beam, but in such manner as not to interfere with the rod Immediately adjoining an overlapping lug, p, of one of the sides of the V-shaped frame is secured on the tube or cylinder a" a collar,

. p', having a forwardly-projecting crank-like bar or finger', p, in a short aperture of which works the lower ball-like end of a projecting arm, Q, of the rod L.- It will be seen that by means of the set-screw n2 working in the Vouter tube or cylinder the inner shaft or rod 'can 'be adj usted at any point, as may be necessary for zo the relative position of the jointer and plowpoint.

By reason of formation of my joiuter of diamond shape, the same is capable of not only cutting on the right or left hand side, according to the position given the plow-point and the mold-board, but when these lower opposite edges become worn, as they do in the course of time, the'jointer can be turned, as stated, on its central securing-bolt by removing the upper bolt, which is replaced when the lower worn portion takes the place of the sharpened edges, which continue the cutting operation on the right or left hand, as before. j Thus it will be seen that my jointer has'four 3 5 cutting-ed ges, two of which-arc always capable of use ou the right or left hand side, as may be desired, the other two being similarly usedy when the former become worn. In Fig. 6 I have shown a modified form of 4o my crotch, 4which consists in providing a curved toothed bar, M, secured to the V-shaped part or member, and with which engages a small pinion or toothed wheel, M', on the long arm or member, as shown, and when this form of construction is employed the-sliding arm or bar is dispensed with.

From what has gone before it will be seen that when it is desired to reverse the plowpointand mol d-board,together with thej ointer,

5o the same is effected by grasping the upper handled end of the lever H and the supplementary lever i', which will free the pawl from the rack, and by moving the lever H toward either side the same will turn the toothed cam, which will 5 5 cause the tube or rod B to revolve, prior to which, however, the grasping of the supplenientary lever will pull on the rod J, pulling rearwardly on the lower end of the lever G, causing the sliding finger to be removed from 6o the aperture in thesliding bar or arm, and at the same time the withdrawal of the dog-like end of the rod j from the recess in the rear side of the plow-point head. After this, by moving said lever H, as above intimated, the

tube or rod B, on which the plow-point head is pivoted, together with the plow-point and mold-board, will be reversed; and this bar is rigidly held in position.

being accomplished,'upon freeing the hold on the levers, the pawl will engage with the teeth ofthe rack, the lower end of the lever G will move forward by reason of its spring,- and the sliding finger will enter the recess of the sliding arm or bar, and the dog-like end of therod j will pass into the corresponding slot or recess of the plow-point head, thus securely retaining the same in position.

Upon moving t-he lever H, as above de tailed, the rod L, upon which said lever is fulcrumed,e ffected the movement of the arm Q, Which,through the agency of its ball-like e'nd and the crank bar or ingerp"of the collar p', caused the reversal of the jointer N, and the outer end of the said rod L moved within the crank or cam of the pivoted post 7c, which affected the turning of the latter and the automatic shifting of the clevis to correspond with the position occupied-by the plow-point and mold-board, which is a desideratum in this class of inventions.

I will now proceedv to more minutely de-v scribe the operation ,of the crotch.

When the lever Hwas moved as above detailed, causing the tube or rod B to revolve, the long arm or member d ofthe crotch,being fast on said rod, turned therewith, and by reason of its pivoted bearing being above thatl of the plow-point and mold-board the same acquired a movement slightly in advance of the V-shaped-part or member d of said crotch, which being connected tothe mold-board gave to the latter the same relative position to the shoe and -landside as it bore before being moved. Vhen-thecrotch is moved, the'onter yroo end'of the'slidiug'arm or bar movesslightly outward, thence downward, and makes about a quarter-revolution, and is then drawn upward and forward with the V-shaped part until f the sliding finger is permitted t'o enter the aperturel in its free end, whereupon the arm or l.
