'COMBINED WHEEL C'ULTIVATOR AND PLOW.

SPECIFICATION forming part of Letters Patent N0.272,460, dated February 20, 1883.

To all whom it may concern Be it known that I, EDWARD L. MURRAY, of Atlanta,-in the county of Fulton and State of Georgia-,have invented certain new and use 5 ful Improvements in a Combined Wheel Gultivator and Plow; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains 10 to make and use the same.

My invention relates to improvements in a combined wheel cultivator and plow, the object of the same being to provide a device of this character which will combine simplicity '25 raking mechanism in position, and Fig. 5 is a modification.

A represents the ground-wheels, B the axles, and G'the frame. This frame (3 is composed of the transverse parallel bars DD D and the 0 central longitudinal parallel bars, D and D, the said transverse and longitudinal bars being secured together in the positions shown in any suitable manner. The front transverse bar is provided near its outer ends with the metallic 3 5 collar a,rigidly secured thereto, and extending below the said bar for the reception of the inner ends of the sliding bars E, which latter are also provided with the collars b, rigidly secured to their inner ends and extending up- 0 ward for the reception of the ends of the bar D. By means of these collars a and b the sliding bars E can be drawn outward or moved inward, when it is desired to increase or diminish the width of the plow to suit existing 5 circumstances, the limit of outward movement of the bars E, however, being regulated by the collars a and b, which meet when the outward limit has been reached. The sliding bars E are retained in any desired adjustment on the 50 bars Dby the "set-screws F, which latter are Application filed May 15, 1882. (No model.)

secured in the collar 1 and bear on the upper surface of the bar D. The central transverse bar, D, supports the entire weight of the frame. This bar Dis provided-on its outer ends with the vertical tongues G, which latter slide or 5 move in the boxes H and guide the frame in its up and down movements. These boxes H are provided on their inner faces with an oblong T- shaped slot, in which the tongues G and the extreme ends of the bar D move. These 6 slots guide and hold the frame from lateral or longitudinal displacement.while the frame with its connected parts are held in vertical adj ustment by the segment-wheel l of the levers I engaging the-racks I, the latter being rigidly 6 secured on the boxes H to one side of the T- shaped slot. The levers I are pivotally secured to the bar D, and theteeth of the same engage the rack on the boxes H, and thereby enable the frame, with its attached parts, to be 7 vertically elevated or lowered, or only one side of the frame, as necessity demands. These levers I'are retained in their proper positions by the spring-actuated dogs J on the levers I engaging with the segment-rack K, the latter 7' being rigidly secured to the bars D. The boxes H are snfficiently long to enable the frame to be elevated suiiiciently high for all necessary purposes, and are provided near their lower ends with an enlarged hub, H, in 81 which the sliding axles B are secured. These axles B are sufliciently long to enable the wheels to run slightly outside of the sliding bars B when the latter are extended to their utmost limit, and they are securely held in the 8 said hubs or boxes H by the set-screws a.

The rear transverse bar, D is removably secured to the rear ends of the bars D and D by the clasps d. This bar is about the same length as the front bar, and has secured to it c an ordinary hay-rake. This attachment is secured in position when it is desired to convert the sulky into a horse hay-rake, and when so used the plows and cultivators, as the case may be, are removed. The two longitudinal bars 93 D and D run centrally throughout the entire length of the frame, and project slightly in front of the same, for the purpose of securing a double or single draft tongue or shafts thereto. The drivers seat M is-removably placed n on these bars, and is adapted to be moved longitudinally, and be secured thereon in any position best suited for the work being done. This seat is provided with the two straps e, oneof which is slightly bent under the bar D while the other remains vertical throughout itsentirelength. Aset-screw,fipassesthrough each strap and secures the seat in position. This construction enables the seat to be re-, moved from the bars or moved and secured to any position best suited for the purpose. The sliding bars E are each provided on the outer ends with the depending slotted swinging arms N, to which the side plows or cultivators are adjustably secured. These arms N are pivotall-y secured to the bars in any desired manner, and are strengthened by the braces Z, and prevented from moving unnecessarily thereby when plows or cultivators are secured thereto. These arms N are provided with registering perforations throughout their entire length, by means of which the plow-clevises' are secured in any desired degree of vertical adjustment.

The side plows or cultivator-beams, as the case may be, are secured to the free ends of the chains 0. These chains 0 pass forward under the pulleys g, secured to the sliding bars,and backward over the same to the handlevers I. These hand-levers P are pivotally secured to the angular bracesQon opposite sides of the frame, and are each provided with a spring-actuated dog adapted to engage the segment-racks It and hold the levers in position. By moving these levers forward the plows are lowered to the ground, and by moving them backward the plows are elevated. The central lever, P, by means of which the central plow or cultivator is regulated, is pivotally secured in the slotted V-shaped box S. This box S is rigidly secured to the hangers h, and is provided with the depending swinging yoke T. This central lever, P,is also pro vided with a spring-actuated dog, while the box S is provided with the segment-1'ack,with which the said dog engages. The lever P is connected to the free end of the chain U, which latter passes over a roller, 1', secured to the bottom of the seat, and thence downward to the plow or cultivatonbeam. By moving this lever forward the central plow or cultivator is elevated, and by moving it rearward the implement is lowered.

The side cultivators, b b, which form a part of my invention, are especially adapted for this style of sulky; but I consider myself at liberty to use plows, barrows, rakes, 850., therewith, as described, without departing from the spirit of my invention. These cultivators b b are adapted respectively for the right and left hand sides of the sulky, and each is provided with one long beam, by means of which it is connected to the sulky, and one short beam, both beams being provided with any number of teeth or sweeps. The two beams are connected together by the straps or crossbars W, which latter are provided with perforations throughout a portion of their lengths, by means of which the beams are moved nearer to or farther apart, as desired. The straps or cross-bars are rigidly secured to the long beams, and the short beams are removably secured therein by pins.

The central cultivator is of ordinary form, and is pivotally secured to the depending yoke in any ordinary manner. The box S, to which this yoke is secured, is removably held in position on the under side of the bars D D by the straps 7t,which latter are ofsuflicient length to extend above the tops of the bars I) and D, where they are turned outward, so as to overlap the said bars. Set screws j pass through these straps and firmly bind the bars D D between the bent upper ends of the straps W and the upper surface of the sides of the box, and thereby clamp the latter firmly in position. The straps h continue downward to the bottomof the hangers and they then turn inward and toward each other and form a limit of forward movement of the yoke T.

The construction, as shown in the first three figures of the drawings, represents the device as arranged to plow a wide row, throwing the earth from the plants. If it is desired to throw the earth on the plants, it is necessary to change the position of the cultivators b N, moving the left to the right, and vice versa. When this is necessary supplemental beams can be attached to the short beams of the cultivator, and therebylengthen them snflicicntly, as shown in Fig. 4. to enable them to be secured in the depending arms N. Other style of plows and cultivators can be secured in place of those shown and described, and answer all the necessary purposes, it not being necessary to especially adapt them for the sulky. When the machine is widened at its front end the axles are also pulled outward an equal distauce and secured so as to enable the plows to run in a direct line. The width of theframe can be decreased to its shortest limit, and one large single breaking-plow be secured thereto, without inconvenience or trouble.

The front ends of all the plows or cultivators are connected to the draft-bar Y, which latter is provided with as many single or double trees as there are horses. When only one small plow or cultivator is in operation only a single-tree need be used, and this can be secured to the clevis of the plow or cultivator, as the case may be.

Where a rake is used, as previously described, it is elevated by the central lever, and kept in a depressed position by a foot-lever, or by any suitable means.

The plows or cultivators can be removed without inconvenienceor trouble and new ones substituted therefor in a. short space of time. Another advantage in the use of this construction is that both sides or only one side of the machine can be elevated at pleasure. As the plows swing on their respective chains the driver can regulate their position with his feet as or before he lowers them.

In all the cases above described, excepting when the rake is used, the draft is applied directly to the ends of the beams; but when the rake mechanism is placed in position the draft is applied directly to the ends of the horizontal ars.

My machine is constructed of metal and wood, the-rigid bars being constructed of wood, while the levers, axles, and boxes are made of suitable metal. 4

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- v 1. The combination, with the central transverse beam of the sulky-frame, provided at each end with a vertical tongue and near each end with a segment and lever, of a segmentrack secured upon said beam and means for engaging the lever with the rack, boxes each provided with a T-shaped slot, in which the vertical tongues of the beam move, and with a rack-bar with which said segments engage, and axles adjustably secured in the lower ends of the boxes, substantially as set forth.
