IMPROVEMENT IN SULKY ATTACHMENTS FCR FLOWS.

Specification forming part of Letters Patent No.1154,306, dated August 18, 1874; application filed June .28, 1873.

To all-whom it may concern:

Be it known that-I, THEoPEILUs WEAVER, of Harrisburg, county lof Dauphin and State of Pennsylvania, have invented an Improvement in Sulky Attachment for Plows, of which the following is a specification:

.The nature and objects of my improvement may be inferred from the following declarations of invention: It consists, first, in a pair of improved detachable compensating-clips, bolted together at their middle, distended by set-screws at their tops, to embrace any ordinary plow-beam between their lower limbs, leaving the plow-beam free from any obtruding parts beneath it, to avoid clogging; second, in a pair. of arms laterally projected from the body of the major clip, by which the axle and seat are braced and adjusted in a peculiar manner by means of the verticallyrolling joints formed on the clip-arms by the stays and horizontally-shitting joints formed by the other ends of the stays pivoted to and set by screws through the trcadle board,

v which is the support of the axle and the seat;

third, in mounting the seat and treadle-frame on a slider on the axle, and in .providing the stays with a series of holes, to make their pitch' on the clip-arms variable at pleasure, so that the seat and treadle-frame may be set more or less toward the wheel of the sulky, to balance the driver over it as a center of gravity, thus .enabling him to regulate the depth of furrow at will bythe disposition of his weight;` fourth, in aplow-beam-controlling mechanism, consisting of a triangular or quadrangular disposition of pivots yconnecting the operating-lever to an .adjustable upright frameprovided with `detents for stopping the lever; also, connecting said lever with the axle byalink hitched adjustably in a foot or arm on the lever, and hitched at its other end in an eye through the axle, 'measurably removed from its end; also, connecting the buttend of the axle, bya horizontal swivel -joint, to a foot or arm on the lower margin of the upright, in whose center the first-mentioned pivot or lever-fulcrum is located; fifth, in connecting and guiding the double-handled operating-lever with.the segment having the detents for the lever-stop, by providingsaid Ystop or `plunger with v an4 angular-hooked bit 5 sixth, in providing the `major clip-body with a vertical slot, and a guiding-seat in front of the slot, for the attachment and adjustment of the upright arched fra-me, to adapt the beam controlling mechanism to plows of greater or less height of beam, the wheel-axle to remain in its normal or horizontal alignment; seventh, in combining the clips, treadle and seat connections, beam-controlling mechanism, and wheel and axle, in such manner that the attachment is universal, independent of fixed mountings on the plow, and corporate or unbroken when detached.

In the accompanying drawings, making a part of this specification, Figure l represents a rear view of my improved sulky attach? ment, attached to a lei't-ilanker plow. Fig. 2 represents a top view of the same. Fig. 3 is a front or edge View of the beam-controlling mechanism. Figs. 4, 5, 6, 7,8, and 9 are sectional views, representing, respectively, the

operating-lever, axle, major clip, arched frame,

minor clip, and detents-plunger.

Similar letters refer to similar parts in the general description.

The major and minor clips', marked respectively m n c and m n e, compose the attaching device. They are connected aboutvtheir middle by through-bolts g', threaded extensively enough to allow the nuts applied exteriorly to the clips to set the clips against the sides of an iron or wooden plow-beam, asv shown at J. The eyes in the clips are made ample enough to pass the bolts g looselyr through them, thus allowing the clips to cant at their ends to align on beams of dierent outline or cross-section, the limbs e e of the major clip being parted, as shown in Fig. 6, to sit against the beam about the swell or eye of the beam, and to afford a good base, on which the whole attachment rests when attached to the beam. The limb c of the minor clip (shown in Fig. 8) is made toset against the opposite side of the beam, and to set midway to the parted limbs of the opposite clip. The clips being applied to the beam as shown in Figs. l and 2, the limbs e e are compressed by the set-screw g, which travels in n, the upper end of the minor clip, and sets in a counter-sink in n', the top of the major clip. This holding devicewill adapt itself -to tapered or square beams, to narrow or broadbeams, and can be instantly detached by undoing= the set-screw g. The other parts of the sulky attachment being supported on the major clip, as hereinafter set forth, it will be observed that no extraneous or fixed mountings are required on the plow-beam, and that the holding device is applicable to either right or left anker plow-beam. It is, therefore, universal and independent in its nature, and leaves the under side of the,

beam free from obstructing parts which would clog the cleaver. The major clip is provided with laterally-extended arms R R1 near the middle of its body for the support of the stays F F', as shown in Fig. 2, which are attached to the clip-arms by the minor clips Q Q', which are a small size of ordinary carriageaxle clips, the stays F F' being perforated with pairs of holesequally distant, to allow the seat and treadle-frame to be more or less shifted relatively to the clip-arms JR R1,which are connected to thestays by hookbolts, or their equivalents, loosely, to allow the plow to roll freely on a horizontal longitudinal joint. The said stays F F' extend `from the clip-arms in direction as shown in Figs. 1 and 2, and have their outer ends adjustably attached to the under side of the treadle H', which is mounted transversely above the axle W W1 W2, so as to be balanced about equally over it, its rest on the axle being secured bya chair, P, which is bolted to the treadle, and has an eye or slotat P'l in it, to freely admit the axle through it, this being required. to compensate by shifting 'on the axle in operating the beam-controlling mechanism. .The said stays FF' arepivoted by bolts y y' to the treadle H', as shown, and are clamped by bindingscrews Z Z' in slots described from the pivots y y' as centers.

The treadle H' is thus adapted to be shifted fore or aft, in relation to middleof the clip attachment, and its adjustment takes the axle with it by .means of the chair P P', by which it is connected therewith, as stated. This longitudinal horizontal adjustment of the treadle and axle is required to compensate for the side draft of the sulky attachment on the gage of the plow, its tendency being to increase the breadth of furrow, and must be regulated either by the plow-clevis or by this mode of adjustment.

As the plow is desired to be left intact in its regulation, so that it may be in working condition when the sulky is temporarily detached in plowing stumpy, rocky, or other irregular area of soil, it is found-expedient to make the attachment self-compensating for its side draft.

The treadle is located centrally over the axle to enable the driver to throw his weight in favor of deep or shallow furrow.

The drivers seat His supported by brace R2 and standards T T on the treadle H', in such position, as shown, to overhang the sulkywheels more or less, in order that the driver may throw his weight on the wheel as a cen-v I ter of gravity in relation to the gage of the plow. VThe treadle H' and operatinglever A N are arranged, also, to enable the driver to stand on the treadle by supporting one hand on the lever-handle.

l The major clip has a vertical groove or seat, S1, on its face, for the reception and guidance of the upright jamb O of the arched frame E E', and has a slot, S2, inthe middle of said seat S1, through which, by a binding screw or bolt, d d', said arched frame is adjustably attached lto the major clip-body, as shown in Figs. l. 2, 6, 7. This vertical adjustment is required to maintain the axle in its normalV horizontal direction, as plow-beams differ in height, and this difference must be made up by adjustment of the arched frameE E', which has an extension, M, at its lower margin, to which the butt-end W of the axle is pivoted by a horizontal connecting-bolt, as shown 1n Figs. l, 2, and 3. The arched frame E E' (shown in Figs. l and 7) has au eye, Gr', as a bearing for the hub G, the fulcrum of the op erating-lever A N, shownseparated and com bined in Figs. 4t and 1, respectively. Said frame E E' has an arch, D, of detents, described with G' as a center, the end thereof terminating in the guard D', which limits the throw of the lever by the bit 1^ of the plunger connected with said lever. The operating-lever A N is provided with two handles, A A, set oppositely on its upper end, is slotted to pass through it one of the plunger-handles, B', and a. rivet, L, by which the plunger is held against the lever at its upper end, said rivet and handle being allowed to traverse the slot as a guide for the plunger. Said lever has also a slot, S, in its body immediately above the arched head of detents on frame E E', and the plunger has a bit, r, whose blade, reaching through said slot S, engages the teeth of the arched frame, and also holds the lever against the side of said frame E E', by a bill-form projection, r', which reaches down on the opposite side of the frame E E', so as not to be disengaged in its office, while the plunger is withdrawn to release its bit r from the de-y tents D. i

The length of the plunger-stem B2 is such as to present the handle B1 and the bit fr thereon through the lever A N at like places in the slots therein, and said slots are prolonged sufciently only to allow a limited throw of the plunger, and to be stopped by the ends of the slots. The plunger has also a duplicate handle, B, opposite to the handle B1, as shown in Fig. 9, so that, when the plunger and lever are united, as shown` in Fig. 3, the fingers may reach and retract the plunger-handle, while the palm of the same hand rests on` and operates the lever-handle on either side, the handles being duplicated to adapt it equally well for right or left anker-plow attachment. A gum band, B3, stretched over handle B1 and a stud on the lever, acts to hold the plunger B2 down to a sure bite in thedetents made for its bit. The lever is also provided with an arm, V, projectin'g from the body of the lever, and perforated to receive a rod, V2, or strap and bolt, by which the lever v:is hitched to the axle, the otherend of the rod or 4strap being pivoted to the axle at W1, as shown, in Fig. 1, the axle 'shown in Fig. 5 being around bar, provided with flattened places for the pivot-holes at W and V, and havingalinchpin-hole at Y.

the position shown:

Case first. If the lever be vibrated away from the plow, the axle remaining compara-V tively level, the 'fulcrum Vwill distort the imaginary triangle, the pivots W and V will approach each other, and the four pivots W W1 V V1 will form a quadrangle; the frame-E E', and consequently the plow, will be `canted away from the sulky-Wheel, or thrown more l or less on its share, as desired, either to take" @wider furrow or to turn a headland, when the plow may ride on the mold-board.

Case second. If from the position stated above the lever be vibrated toward'the plow, the fulcrum V1 will be carried into the interior of the imaginary triangle, and the frameV E E', andI consequently the plow, will be canted toward the sulky-wheel, or directed to gage a narrower furrow.

If the sullry-wheel is traveling'upgrade in relation. to the plane of .',the plow, the lever must be vibrated according to case rst. Ifl on downgrade, it must be vibrated according to case second.

The intermediate grades between high and low surface, between the plow and the wheel, may all be substantially anticipated by the driver by'selecting a proper detent for the lever, to equalize the operation of drawing a uniform furrow over rolling surface, the roll of the beam-Gauting mechanism being sufficient to balance the inequality either way.

,A long-felt want, it is believed, is `met by this attachment, which is adaptedto all plow structures in common use, whether of iron or wooden beam, right or left hand flanker, for level or rolling surface, in a cheap, convenient, unmistakably simple, and perfectly self-constituted mechanism.

Having thus fully described 4my invention, what I claim as new, and desire to secure by Letters Patent, is

1.-'The clamp-holder constructed substantially as herein setforth, in combination with the plow-beam J and the sulky attachment vproper, for the purpose set forth. 2. The major clip m' 'n' c', providedwith the arms R R1, in combination with the stays F F' Vof the treadle H', united by the axle-clips Q Q', or their equivalents, to form the rolling joint, substantially as and for the purpose herein set forth.

3. The stays F F'7 pivoted to the treadle H' at y y', and clamped adjustably by the binding-screws at Z Z', in combination with the sulky-axle W W1 W2, by means of the chair P P', or its equivalent, when the fore and aft shifting of -the axle is thereby effected, substantially inthe manner as and for the purpose herein set forth.

4. The groove S1 and slot S2 in the major v clip, in combination with the vertical jamb O of the arched frame E E', secured together by the bolt and'nut d d', or their equivalents, for

the purpose herein set forth.
