SPECIFICATION formiug part of Letters Patent No. 225,207, dated March 9, 1880. Application led November 29, 1879.

To all whom 'it may concern: l

Be it known that LLOUIs BERTHIAUME, of St. Paul, in the county of. Ramsey and Sta-te of Minnesota, have made certain new and use ful Improvements in Sulky-Plows, which improvements are fully set forth in the following specification and accompanying drawings, in which- Figure l is a sectional side elevation. Fig. 2 is a plan view. Fig. 3 is a sectional front elevation 5 Fig. 4, enlarged detail views of the hub and chilled box; Fig. 5, enlarged detail views of the colter attachment; Fig. 6, enlarged detail views of the standard-clamp; Fig. 7, enlarged detail views ofthe swivelclamp for connecting the beam to the sulky- This invention relates to sulky-plows5 and it consists in certain improvements therein, as hereinafterI more fully set forth, and pointed out in the claims.

A is the mold-board, B the beam, and C the standard. The latter is secured to the plow in the us'ual manner, and runs up alongside the beam in a curve, the center of whose radius is at a point near the forward end of the beam. D is a clamp bolted or rivetedto the beam, and arranged to inclose the standard, in which the latter is held by a set-screw, a, (see Fig. 6,) countersunk cavities being formed in the standard to receive the point ofthe set-screw. By this means the plow may be' adjusted higher or lower with relation to the beam.

The rear end of the beam runs backward and downward at Df, and is attached to the' lower part of the standard by a flexible arm, c, pivoted at its lower end to the standard C, and having its Lipper end pivoted to a screwbolt, c', passing through a screw-threaded oriiice near the end of the extension D" of the be adjusted higher or lower to elevate or de press the clevis or the nose of the plow.

By these two adjustments-viz., the standard C and flexible connection c-the plow may be arranged to cut any desired depth or the beam set at any angle.

E is the main frame of the s ulky attachment, consisting of one single bar of iron with two legs, E2 E3, bent down at right angles thereto.

The leg E2, on the furrow side, is secured to a casting, F', upon which the furrow-wheel G is journaled, while the opposite leg, E3, is provided with va slide, F2, upon which the landside wheel G2 is journaled.

The slide F2 will be arranged to slide up and down upon the leg E3, and will be connected by a rod, d, to a bell-crank lever, H', arranged to act in conjunction with a toothed segment, e', and spring-dog g, to raise and lower the wheel G2 and hold it at any desired point.A

I is a bent shaft or lifting-bail, to which the beam B is attached, and which is pivoted at either end in the lower parts of the legs E2 E3, and provided on the furrow end with' au arm, I2, which, in turn, is connected by a rod, d2, to a lever, H2, arranged to act in conjunction with a perforated segment, e2, and a spring-dog, g2, to raise and lower the beam and plow. g

The top of the frame E will be provided with a brace, E4, riveted to the frame at either end, at h', and raised up from it in the center, at h2, to act as a stiftener to the frame.

The clamp for connecting the beam B to the bail I consists of a circular plate, i', having boxes @2 to connect it to, but leave it free to revolve around the bail, and a similar plate, i3, having ears k running up on ea'ch side of the beam, and riveted or bolted thereto, the two plates being secured to eachother by setscrews m. These setscrews pass through slots in the lower plate, i', (see upper igure in Fig. 7, which is an inverted or bottom-plan view of this cla-mp,) and are tapped into the upper plate, i3, so thatA the beam maybe oscillated to the extent or' the length of the slots. The two plates will be arranged so that one fits into the other a short distance, (as shown in the lower ligar-.e ot' Fig. 7, which is a sectional elevation of this clamp,) to form a center upon which the plates oscillate, so that they will retain their relative positions and prevent the strain coming upon the set-screws.

Collars n on the bail I', outside the boxes?, enable the whole clamp to be adi usted laterally.

By setting up the set-screws m the plates IOO may be clamped together so as to form a rigid joint or clamp, if desired.

The land-side, it will be seen at A2, runs back only far enough to form a support for the standard C, while, at the same time, it is sufliciently long to hold the plow in place and cause it to travel in a straight line.

In an ordinary plow with a long land-side and the beam rigidly clamped upon the bail, it is necessary to remove the plow from the ground in turning corners, or else turn in a very long sweep, but this is a waste of time and soil, but by arrangement of a short landside and a swivel-clamp connection between the beam and bail I am enabled to turn a very short, almost square, corner without lifting the plow from the ground. When thehorses begin to turn the corner the tonguel? is turned first, carryin g the wheels G' G2, bail l', and upper plate, i3, with it as far as the slots in the plate 'i' will permit before the beam and plow are affected. Thus the horses are at a considerable angle from the beam before they begin to turn it 5 hence the plowis turned almost square around, thus operating much in the same manner as a Wagon whose forward wheels cramp around underneath the box or body. This is a great advantage, as it lessens the labor and saves time and land at the corners of the field.

Another important office of the swivel-clamp is to allow the wheels and 'frame to oscillate independently of the plow, so that any rough or uneven surface which the land-side wheel may meet, or any sidemoveinentof the tongue, will not be communicated to the plow, but the latter will run steadily under all circumstances.

The colter K' is secured to the beam by an adjustable clamp consisting of two cheekpieces, p' p2, bolted or riveted to the beam B, and provided with two upright bolts, of" r2, which hold two .slotted plates, t' t2, one above and one below the beam. These slotted pieces are each provided with large holes in one end, through which the shaft K2 of the colter-hanger K3 passes. Between the plates t' t2, and around the colter-shaft K2, is a collar, t, secured to the shaft by a set-screw, t4. The lower part of this collar is provided with lugs t5, (see lower iigure in Fig. 5, which is an inverted perspective view of this collar,) adapted to fit into corresponding slots in the lower plate, t2, so that the collar will be allowed lateral play to a limited extent, so that should the colter meet with any extraordin ary obstructions it will be turned aside and saved from breakage, while, at the same time, the two plates t' t2 allow of its adjustment to match the share and land-side.

Attached to the frame E' E2 Ef is another frame, consisting of a beam, L, attached to the u leg E2 atone end, and running forward and connected to the otherleg, E3, by a right-angled rod, M', `the foot-rest M2 being attached to this rod M', asshown. NN2 are two slotted plates secured to the beam'L, and to which the tongue P is bolted, so that it may be adjusted laterally to adapt it to the line of draft. R' is a small standard bolted to the foot-rest M2, and provided with an upright shaft, R2, around which a spring, o, is coiled, and which is held by guides u u on the standard R. R3 is a foot-lever pivoted to the shaft R2 and connected to the standard R' by a rod, R5.

Upon the bottom of the shaft R2 is a crosspiece, RG, (see lower detached figure of Fig. 3,) the whole adapted to be used as a lever by the driver to force the forward part of the beam downward, and consequently the nose of the share, when first starting, to assist the plow in entering the ground, and thus avoid the blind furrow 7 which occurs where no such help is used, where the first five or six feet is required to get the plow into the ground.

ln Figs. 3 and 4 is shown the method of arranging the hubs and axle-boxes of the wheels G G2, which consists of a box or skein, w, made of chilled cast -iron or steel, and tapered on the outside, and provided with ribs .r on the sides, and adapted to fit into a correspondingly tapered and grooved hole through the hub y', the skein being held in place by a set-screw, y2. Collars z' around the journal or axle z2, next the slide F2 and casting E', act as sand-guards, to prevent sand or grit getting upon the axles.

By this arrangement, when one box wears out it can be replaced at small expense and without throwing away the whole wheel.

rlhe bends in the frame E', where the legs E2 E3 start, will be stiftened by castings, as shown, thus producing a very light, strong frame, not liable to become broken or out of order. The brace E4 greatly stiffens the frame without adding materially to the weight or expense.

The simplicity of the apparatus for elevating and depressing the land-side whee1G2 is an important feature of my machine, as it dispenses with many pieces, and is direct-acting in its movement.

The curve in the standard G enables me to adjust the plow higher or lower without cramping or throwin the connecting-rod o too much out of line or altering the position of the olevis end of the beam. The flexible connection c and the adjustable standard C also enable-me to adapt the plow to deep or shallow plowing, side-hill or other uneven work, or to compensate for any wearing the share and nose may be subjected to.

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

1. The combination of the colter-shaft K2 and collar t3, provided with lugs t5 t5, adapted to t in slots in the plate t2, to allow lateral play of the collar, with the beam B, slotted clampingplates t' t2, cheek-plates p' p2, and bolts t4 r' r2, substantially as described, and for the purpose set forth.
