Letters Patent No. 63,247, dated Zlfarch 26, 1867.
Be it known that I, W. H. H. HEYDRIGK, of Chestnut Hill, in the county of Philadelphia, and State of Pennsylvanim'have invented a new, useful, and improved Steam Gang-Plough; and I do hereby declare the following to be a full, clear. and exact description of the same, sufficient to enable one skilled in the art to which the invention appertainc to make use of it, reference being had to the accompanying drawings, which form a part of thisspecification, and in whieh-- Figure 1' is a plan or top view.
Figure 2 is a side elevation.
-Figures 3 and 4 are sections through the respective shafts, by which the ploughs are ,raised and lowered, and showing the plough-levers in elevation. I
Figure 5 is an elevation of one of the cam-shafts, showing the disposition of the cams.
Figure 6 is an end view of the cam-shaft.
The invention consists of an arrangement of devices by which the ploughs are caused serially to enter the ground, on a given line, at right angles to the course of the machine, and to be withdrawn in a similar manner, so that although they are arranged in a receding series, obliquely to the line of motion, they shall begin their furrows and terminate on a line at right angles to the course of the machine. It is necessary to arrange the plonghs in a receding series, as indicated in fig. 1, or else the furrow-slice from plough 8 would jam against the land-side of No. 7, No. 7 against No. 6, and so on, which would effectually choke and stop the machine. No. 1 delivers its furrow and passes on suiiiciently to allow the furrow from No. 2 to fall in its rear, and so on through the series, but on reaching the end of the land or side of the field, if the ploughs, are simultaneously withdrawn from the ground, there is a three-cornered piece of land left untouched equal in length to the distance of the point of plough 8 behind the point of plough 1, and equal in width to'the aggregate width of the furrows. The corresponding incompleteness of work is seen in starting in with all the ploughs simultaneously, and this incompleteness is what I aim to avoid by an arrangement of devices by which the ploughs commence their work and leave it in line at right angles to the line of motion of the machine.
i In the drawings, A represents the frame or truck upon which the steam engine is imposed, and B is the roller which forms the main support and driving-wheel of the machine. '1 do not make any claim to the arrangement of the driving mechanism, and will therefore state cursorily that G is the boiler; D, the stack; E E, the steam cylinders; F, the piston-rods, andG, the crank on the axis of the driving and supporting drum B. The forward end of the frame A is supported by the caster-wheel H, which also'forms a guide-wheel, as it is attached to a carriage, I, movable on a vertical axis by means of a shaft, J, and pulleys K K, operated by the handwheel L. The minor arrangements of the engine, such as the shuttle-valve M, safety-valve N, whistle O, steam pipes P, do not probably require more explicit description. Underneath the platform, and suitably connecting the eccentrics on the shaft of the driving-wheel with the steam-valve, is a link-valve motion, which need not be particularly described, as the motor is not the novel feature of this invention. To a bar, a, at the rear of the frame A, are pivoted the fore-ends of the beams b b I), to which the ploughs 1, 2, 3, 860., are attached. The ploughs may be of the ordinary character in use in gang-ploughs, and are so attachedto the beams by standards a c, draught-rod d, and suspcnsory cords g, as to be adjustablefor depth of furrow and width of land. 0 e is a frame rigged out from the upper part of the frame A, supporting the. rollers ff, over which the cords g are passed; these cords are so attached to the plough-beams as to aii'ord the means of raising them when the levers g are vibrated forward. The motions of the lever g are obtained by means to be presently described. Upon a pulley or shoulder, h, of the drum B is a band, 2,which also passes over the loose pulley j of the shaft K, which, by a band, m, revolves the loose pulley n on the shaft 0. Whenever the machine is' in motion the bands int and pulleys jn are revolved, and the pulleys are caused to rotate their respective shafts k 0, whenever they are engaged therewith, by the motions of their respective clutches q. The loose half of the clutch is operated by the lever r, and by engagement with its fellow causes the shaft is to revolve; this shaft, shown more fully in fig. 5, has eightcams upon it, arranged in a spiral form, half encircling the shaft, as secnin fig. 6. A similar clutch arrangement, q, is provided of the shaft 0, and isoperated by the lever s. This shaft has a spiral series of eight cams, similar to the shaft lejust described. The purpose of the cams on the shaft k is to elevate the lovers 9 by pressure against their lower ends,the spring-dogs t engaging the notches 'u, and maintaining them in their erect position, as shown in fig. 3, while the purpose of the cams on the shaft to strike on the tails of the dogs 25, and by disengaging them from the notches u of the lovers to let the latter fall, as seen in the position, fig. 4:. The shafts k and o are only revolved upon the occasions of finishing and commencing furrows, respectively, that is, to raise the ploughs from the ground and to lower them to the ground, respectively. These motions, as they are required, are obtained by the levers r s, and the motions of the pulleys j n are so timed that the shafts k 0 will make half a revolution while the machine is advancing a distance equal to the advance of the plough 1 before the plough 8. The cams being arranged spirally one-half around the shafts k n will, when brought into action, respectively elevate and depress the whole series of ploughs while travelling a space equal to the distance which plough 1 precedes plough 8, so that when the plough 1 has arrived at the point where the ploughing is to stop, the operator by the lever r throws in the clutch on the shaft is, which, revolving, raises the ploughs in the order of their precedence, terminating their action in a line at right angles to the line of mot-ion of the machine. A corresponding result,is obtained when starting in a new furrow; as soon as plough 1 arrives at the point shaft 0 is thrown in gear by the lever s operating the clutch, and the ploughs are dropped one by one, in order of their precedence, by the successive engagements of the cams on the shaft 0 with the dogs t, by which the lovers are maintained in their vertical position, keeping the ploughs elevated above the ground. The shafts k 0 may be rotated by a hand-crank, if desired, or it may be used to bring the shafts to the point where their cams will immediately commence their elevating or dropping action, for which they respectively are adapted. The rotation by hand is also useful to raise a portion of the ploughs when in the short rows when the field is not square. The end bar 0 of the upper frame is made adjustable forward or backward by means of the crank and pinion o w, the latter engaging with the rack 90 on the bar g, which is secured to the bar a; by this means the ropes are practically lengthened or shortened, so that the ploughs may be dropped to a greater or less distance vertically, and the depth of furrow thus regulated, or the slack of the chains 9 regulated, when ploughing where the ground is uneven. Attached to the lower side of the bar 0 are hooks 1 to which the loops of the cords g may be fastened; by this means the plnughs may be temporarily suspended while moving from place to place, independently of accidental dropping by a casual rotation of the shaft 0. Thismodc of suspension of the ploughs is also used to hold a portion of them up when a less number than the whole is wanted. The bar 0 has mortises in it, through which the side bar 0 passes as the bar 0 slips back and forth, underv the action of the pinion v and rack 10. The hand-bar z operates the shaft a upon whose end is the director-wheel b, which moving along at the edge of the previous furrow indicates to the steersman how to guide the machine, and is raised in turning anotch or the bar catching behind the post. The cams only occupying one-half of the circum: fcrence of the shafts, they maintain such a position when respectively out of gear, and the other in gear, that the cams of is do not interfere with the levers when the ploughs are being lowered, nor the cams of o interfere with the dogs it when the ploughs are being raised. The face of the caster-wheel is made concave, controlling more effectively the motions of the machine.
Having described my invention, what I claim therein as new, and desire to secure by Letters Patent, is
1. The shaft k, rotated by the clutch-connection or by hand, as desired, and operating by means of a spiral series of cams to elevate the plough consecutively from the ground, substantially as described.
2. The shaft 0, rotated by the clutch-connection or by hand, as desired, and operating, by a spiral series of cams, to trip the dogs or their equivalent, consecutively to lower the ploughs to the ground, substantially as described.
3. The combination with the cam-shafts k 0 of the levers g and spring-dogs t, operating substantially as described.
4. The director-wheel b, shaft a, and bar 2, constructed and operating substantially as described. 5. The bar 0, supporting the cord pulleys, and adjustable by devices, substantially as described.
