"Upon an axle, A, supported on the usual carrying wheels, B, B, is mounted a main frame, C, and on the main frame a seed-box, D, the slides of which may be operated in any of the well-known ways. In bearings, E, in the front portion of the main frame, is hung, so as to rock or turn therein, a zigzag or crank shaft, F, (shown detached in Fig. 2,) and to the cranks or wrists, a, a, a, of this shaft are connected, seriatim, the drag-bars, b, b, b, by means of bows or yokes, c, each bow or yoke taking two of said wrists, as shown in Fig. 1. To the rear ends of these dragbars, b, are attached the shoes or hoes, G, in any of the usual wellknown ways. In the projecting rear portion of the main frame, C, there is hung a shaft, d, upon which there is a lever, e, by which it can be rocked or rolled in its bearings. At suitable distances upon this shaft, d, there is placed a series of levers, ƒ, ƒ, one for each shoe or hoe, which are kept in their proper positions on the shaft by pins, 1, 1, or other suitable devices, but which can be moved independent of the shaft or of each other, or all together, as will be explained. The levers, f, have a hub or swell, g, at their central portions, where they are slipped onto the shaft, d; and into each one of these hubs

"Upon an axle, A, supported on the usual carrying-wheels, *B, B, is mounted a main frame, C, and on the main frame a seed-box, D, the slides of which may be operated in any of the well-known ways. In bearings, E, in the front portion of the main frame, is hung, so as to rock or turn therein, a zigzag or crank shaft, F, (shown detached in Fig. 2,) and to the cranks or wrists, a, a, a, of this shaft are connected, seriatim, the drag-bars, b, b, b, by means of bows or yokes, c, each bow or yoke taking two of said wrists, as shown in Fig. 1.

jecting ends of said levers serving as handles for the operator to seize and work separately, when necessary to do so, or he can raise the whole series by seizing and working the lever, e. One end of the shaft, d, projects through the timber of the main frame, for convenience of placing the parts, and upon it is a lever, H, and a spring-locking lever, i, connected with it, both of which levers the operator may grasp at once, and by pressure first unlock the catch, and then move the main lever, H, and the shaft, d, as well as the parts connected with it. The catch or locking lever, i, takes into or against a stopplate, j, on the main frame, when not otherwise controlled. The upper portion of the lever, H, serves as a handle to work it by, and to the lower end of it is pivoted a rack-bar, m, which takes into a pinion, n*fastened on the end of the crank or zigzag shaft, F, and wher the pinion, n, is turned the crank shaft is also turned, and, as it is turned, it shifts the shoes or hoes into a zigzag or a straight line, as the case may be. When the lever, HI, and the zigzag shaft, F, and their several connected and operative parts, are in the positions shown by the black lines in Figs. 1 and 3, the shoes or hoes, G, are then in a straight line across the machine; but, when the lever, H, is shifted into the position shown by the red lines in Fig. 3, it turns the shaft, and moves the parts connected with them, and the shoes or hoes will then stand in a zigzag line across the machine, as shown by the red lines, or in what may be termed two lines, one in advance of the other; and, that the shoes or hoes may be thus moved into one or two lines, and still be susceptible of being raised up separately, or in their series capacity, their connections and attachments must all be hinged or yielding. When there is an odd number of shoes or hoes on the machine, the odd one should be in the rear series, in which case there would be no necessity of locking the lever, H, when the shoes were so arranged, as the greater resistance on the greater number would always keep them so. But, if an even number of shoes be

as handles for the operator to seize and work separately, when necessary to do so, or he can raise the whole series by seizing and working the lever, e. One end of the shaft, d, projects through the timber of the main frame, for convenience of placing the parts, and upon it is a lever, H, and a spring-locking lever, i, connected with it; both of which levers the operator may grasp at once, and by pressure first unlock the catch, and then move the main lever, H, and the shaft, d, as well as the parts connected with it. The catch or locking lever, i, takes into or against the stop-plate, j, on the main frame, when not otherwise controlled. The upper portion of the lever, H, serves as a handle to work it by, and to the lower end of it is pivoted a rack-bar or connectingrod, m, which takes into a pinion, n, fastened on the end of the crank or zigzag shaft, F, and when the pinion, n, is turned the crank-shaft is also turned, and, as it is turned, it shifts the shoes or hoes into a zigzag or a straight line, as the case may be. When the lever, H, and the zigzag shaft, F, and the connecting-bar, m, and their several connected and operative parts, are in the positions shown by the full lines in Figs. 1 and 3, the shoes or hoes, G, are then in a straight line across the machine; but, when the lever, H, is shifted into the position shown by the dotted lines in Fig. 3, it turns the shaft, and moves the parts connected with them, and the shoes or hoes will then stand in a zigzag line across the machine, as shown by the full lines, or in what may be termed two lines, one in advance of the other; and, in order that the shoes or hoes may be thus moved into one or two lines, and still be susceptible of being raised up separately, or in their series capacity, their connections and the attachments must all be hinged or yielding. When there is an odd number of shoes or hoes on the machine, the odd one should be in the rear series, in which case there would be no necessity of locking the lever, H, when the shoes are so arranged, as the greater resistance on the greater number would always

used, and an equal number in each row, then the lever would have to be locked or fastened in both of its positions.

"It is obvious that other mechanical devices may be used for shifting the shoes or hoes from a straight into a zigzag line or vice versa. I have devised several ways of accomplishing this movement, as, for instance, a sheave, pulley, or chain-wheel may be keyed to the end of the crank-shaft, and to this sheave or wheel a chain may be attached, and, passing around it, extend thence to the lever, so that, by working the lever, the same effect would be attained as by the rack and pinion.

"Another plan may be as follows: A crank or cross-arms may be placed on the turning-shaft, and, by means of connecting-rods, which connect the cranks or arms with the levers, the shaft may be turned, andthe shoes thus thrown into a straight or zigzag line, as may be desired; or, instead of the crank-shaft to shift the shoes, the shoes may be united in sets to different bars, which may be straight, both bars being united to cross-bars or heads at their ends. Now, by shifting these two bars, they will shift the shoes attached to them, and change them into the positions herein-above described. When the hoes are set in a zigzag line, as above mentioned, and are in that position raised up, a pin, 3, in the extreme end of the shaft, d, will take against a pin, 4, in the lever, H, and thereby shifting the hoes into more nearly a straight line, as they rise, or into quite a straight line, depending upon the extent to which they are raised.

"Having thus fully described my invention, what I claim therein as new, and desire to secure by letters patent, is:

"1. So attaching the shies or hoes

keep them so. But, if an even number of shoes be used, and an equal number in each row, then the lever would have to be locked or fastened in both of its positions.

"It is obvious that other mechanical devices may be used for shifting the shoes or hoes from a straight into a zigzag line, or vice versa. I have devised several ways of accomplishing this movement. The rack-bar or connecting-bar, m, may be used for this purpose, and thereby the shoes or hoes may be shifted from a straight to a zigzag line, or vice versa, said connecting-bar, m, being held in position, if desired, by any of the usual mechanical devices for that purpose; second, by means of a sheave, pulley, or chain-wheel, which may be keyed to the end of the crank-shaft, and to this sheave or wheel a chain may be attached, and, passing around it, so that, by means thereof, the same effect can be attained as by the rack and pinion.

"Another plan may be as follows: A crank or cross-arms may be placed on the turning-shaft, and, by means of a connecting rod or rods, the shaft may be turned by the operator, and the shoes thus thrown into a straight or zigzag line, as may be desired; or, instead of the crank-shaft, the shoes may be united in sets to different bars, which may be straight, both bars being united to cross-bars, or heads at their ends. Now, by shifting the relations of these two bars, and by the means aforesaid, or by the connecting rod, m, the operator can shift the shoes or hoes attached to them into the positions hereinabove described. When the hoes are set in a zigzag line, as above mentioned, and are in that position raised up, a pin, 3, in the extreme end of the shaft, d, will take against a pin, 4, in the lever, H, and thereby shifting the hoes into more nearly a straight line, as they rise, or into quite a straight line, depending upon the extent to which they are raised.

"Having now described my invention, what I claim as new and desire to secure by letters patent, is:

"1. The shoes or hoes of a seed

"2. I also claim in combination with a series of shoes or hoes that are capable of being changed from a straight to a zigzay line, or vice versa, the so connecting of said shoes, by independent levers, to the lifting-bar, as that they may be raised by the operator individually, or as a whole, substantially as described.

*The cause was heard in the circuit court, on pleadings and proofs, and decision rendered in May, 1881, (Davis v. Brown, 19 Blatchf. 263, S. C. Fed. Rep. 647,) in pursuance of which an interlocutory decree was entered, in June, 1881, declaring the reissued patent to be valid, and to have been infringed as to all its claims, and awarding a recovery of profits and damages, and a perpetual injunction. On the report of a master, a final decree was entered in February, 1882, by which the plaintiffs recovered $5,689.91, as damages and costs. The defendants have appealed to this court.

The specification of the original patent stated the purpose of the invention to be to change the seeding shoes or hoes from a straight to a zigzag line, and vice versa; and also to so hang the shoes or hoes as, in addition to the shifting process, to allow the shoes or hoes to be raised all together, or any one separately. The mechanical means described in that specification for shifting the shoes are these: In the front part of the machine is a rotating shaft, with cranks on it, so arranged that the shaft does not have a straight continuous
