SPECIFICATION forming part of Letters Patent No. 601,516, dated March 29, 1898.

Application filed Augu t 18, 1897. Serial No. 648,652. (No model.)

T0 all whom, it may concern:

Be it known that I, HENRY BENSON LAM- BERT, of the Sixth ward, in the parish of St. Helena and State of Louisiana, have invented a new and useful Improvement in Plows, of which the following is a full, clear, and exact description.

The object of my invention is to provide a plow so constructed that the point and the landside may be raised and lowered one independently of the other and whereby the handle of the plow maybe likewise independently raised and lowered.

A further object of the invention is to provide a peculiar form of stock, which stock will consist of side members adj ustable on the beam and a main member pivoted between the side members and capable of forward and rear movement on the beam, the main memberof the stock being adapted to carry the share.

A further object of the invention is to improve the plow in the details of its construction, rendering the same much more simple and durable and the plow in its entirety more effective than the majority of plows of its type.

The invention" consists in the novel con struction and combination of the several parts, as Will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, f0rming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the improved plow. Fig. 2 is a plan view, and Fig. 3 is a bottom plan view, of said plow. Fig. 4is a vertical longitudinal section illustratin g the locking device for the stock and the locking de' vice for the connecting medium between the stock and the landside.

The stock A is preferably made shorter than the ordinary stock, and the handles B are pivotally attached to the stock, one at each side in the customary manner, the pvot-bolt for the handles being designated by the numeral 10. The aperture for the bolt 10 in the beam is small and horiz0ntally elongated, so that the handles may be adjusted backward and forward. The clevis consists of a horizontal bow-section 11, having a series of apertures 14 made therein, the bowsection being firmly attached to the beam and a pvot-section 12,

likewise of bow construction, held to travel over the fixed section 11, carrying a pin 13, which may be entered into any one of the apertures 14, as may be found desirable in in the beam to receive the said bolt, so that the stock through the medium of these outer arms may be raised or lowered at will.

The intermediate or central arm or section 17 of the stock is of such length as to enable it to extend upward through the stock A, an opening 30 being vertically made in the stock for the reception of this arm or section, and the said stock is elongated or of such length as to permit of the central section or arm 17 of the stock being moved forwardly or rearwardly, so as to depress or raise its lower portion. The upper end of the central arm or section-17 of the stock is reduced and exteriorly threaded to receive a washer 28 and a lock-nut 29, the locknut and washer actin g in the capacity of a set-screw and permitting the said central section or arm of the stock to be secured wherever it may be adjusted.

Two uprights 20 are located at the rear of the implement, one at each side of the beam. The lower ends of these braces are forwardly and downwardly curved and are pvot-ed to the outer arms 15 of the stock C by a pivotbolt 20". The upper ends of the uprights are made to diverge and are carried one to an engagement with the outer face of each hanare adjustably connected with the handles B,

and to that end are provided with a series of apertures 23, a bolt 24 being passed through the two handles and registering apertures in the uprights, the said bolts being preferably provided with two nuts at each end, one engaging with the inner face of a handle and the other with the outer face of the upright bearing against the handle. Under this construction it will be observed that the handles will be raised or lowered, as desired, and that the uprights may be carried bodily upward or downward, so as to regulate the position of the side arms or sections and 16 of the stock C.

A landside D is pivoted at its forward end between the sections of the stock, preferably by the pivot-bolt 18, connecting the bottom of said sections, and an adjustingbar is pivotally attached to the inner face of the landside at is free end, the said adjustingbar being preferably round, so as not to obstruct the passage of the earth, and this adjusting-bar is carried upward between the uprights 20 and through an opening 26 made in the beam A. The upper portion of the adjusting-bar is threaded, and nuts 27 27 are placed on the threaded portion of said adjusting-bar 25, bearing against the top and bottom faces of the beam.

The landside is reinforced at the rear po rtion of its Outer or wearing face by an at tached bar 33. Therefore the wear of the landside is on the attached bar 33, which may be removed and replaced by a perfect one when worn out. A flange 32 is secured to the forward edge of the lower portion of the central section of the arm 17 of the stock, as shown in Figs. 1 and 3. The plowshare and point 31 are bolted or otherwise secured to this flange, the share shown in the drawings being that of aturnplow. The central arm or section 17 of the stock is at its lower end made of such Width, as shown in Fig. 3, as to fill the space between the forward portion of the landside D and the left-hand outer member of the stock.

When the central or main section or arm 17 of the standard C is moved forward, it will throw the point of the plow down and the point or forward end of the beam up, thus causing the plow to take the ground in a manner to plow well in grass and trash where ordinary plows would choke. The peculiar construction of the standard also enables the operator to run dull and worn points with case and to so shorten the traces that the horse will travel close to the plow.

The adjustingbar 25 enables the operator to raise or lower the landside to suit the character of the ground being plowed, and as the bar is round in cross-section it will catch very little dirt. The standards 20 as heretofore stated, enable the handles to be raised and lowered, and also enable the stock C and landside to be carried bodily forward or rearward, the adjusting-bar 25 of the landside being capable of sufficient movement in the beam to admit of such manipulation.

The peculiar construction of the clevis will enable the operator to give the plow more or less land and to plow close to corn, cotton, &c., while the horse walks at one side of the line of the furrow to be made by the plow.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with a plow-beam, of a stock comprising three sections or arms, the outer sections or arms being pivoted one to each side of the plow-beam, the central arm or section having vertical and. lateral movement in the plowbeam, all the sections or arms of the stock being pivotally connected at their lower ends, for the purpose set forth.

2. The combination, with a plow-beam, of a stock comprising three arms or sections, the Outer arms or sections being adjustably pivoted to the plow-beam, one at each side, the three arms being pivotally connected near their lower ends, and the intermediate arm or section having vertical and lateral play in the beam, a fastening device for the central section of the stock, and means, substantially as described, for attaching a plowshare to the said central section of the stock, as and for the purpose specified.

3. The combination, with a plow-beam, of a stock composed of two outer and an intermediate arm or section, the outer sections or arms being pivotally attached at their upper ends to the beam, one at each side, all of the sections being pivotally united near their lower ends, the intermediate section or arm being adjustable vertically and longitudinally of the plow-beam, a looking device for the ntermediate section or arm, a landside having its forward end held between the sections of the stock, and an adjusting-barpivoted to the rear end or heel of the landside and adjustably carried through the beam, and a looking device for the adjusting-bar of the landside, for the purpose set forth.

4. The combination, with a plow-beam, of a stock constructed in three sections or arms, the outer sections being pivotally attached to the beam, one at each side, the three sections being pivotally connected at their lower ends, the central section or arm having lat eral and vertical movement in the plow-beam, a looking device for the said central section or arm, a landside having its forward end pivoted between the sections of the stock, an adj ustingbar pivoted to the rear end or heel of the landside and adjustably carried through the beam, a looking device for the adjusting bar of the landside, a reinforcing-bar secured to the wearing-surface of the landside, anda flange projected froni the forward edge of the central section or arm of the stock, the said flange being adapted to receive and support a share, as and for the purpose specified.
