CHECK- RWER.

SPECIFICATION' forming part. of Letters Patent o. 455,380, dated July '7, 1891.

Application iled February 25, 1891. Serial No. 382,739. (No model.) l

To all whom, it may concer-1t.-

Be it known that I, JOSEPH C. BARLow, ot Quincy, in the countyof Adams and State of Illinois, have invented certain new and useful Improvements in Anchors for Check-Bowers; and I do hereby declare the following to be-a full, clear, and exact description of the same, reference being hadA to the accompanying drawings, forming a part ot' this specification, and tothe figures ot` reference marked thereon.

Thisinvention relates to improvements in that class of anchor devices for check-row cords or wires for which Letters Patent N o. 373,170 were granted to me November l5, 1887;

and it consists in the novel construction and arrangement of the parts designed to simplify and improve the device and render it more efficient in action.

In the accompanying drawings, Figure 1 represents the improved anchor in perspective as set for start-ing the check-rower. Fig. 2 is a similar view showing the anchor upon the return or approach of the check-rower. Fig. 3 is a side elevation with straight lever. Figs. 4, 5, and G are top plan views illustratadjustment or motion.

Similar letters of reference in the several figures indicate the same parts.

As in mypriorpatented device, this anchor is furnished with an anchor-pin 1, a base or frame 2, a handle or lever 3 for setting the anchor and putting tension on the cord or wire, a foot-piece 4. to aid in inserting the anchor-pin, a holding and releasing device 5 for engaging the check-row cord or wire, and a tension device G, operating, when the holding device is released, to permit of the extension of the cord or wire to accommodate the lateral adjustment of the planter on its return movement. lVhile all of these elements, abstractly considered, are found in my improved anchor, they are constructed, arranged, and combined in a somewhat different manner, as will presently appear. The frame or head 2, with its foot-piece 4, is clamped upon the end or head of the anchor-pin 1 in the same or an equivalent manner to that described in my said prior patent; but the handle or lever 3, instead of being rigidly secured to the head 2, is pivotally attached thereto by a transverse bolt or pivot-pin 7. A shoulder or stop 8, engaging the casting or head 9 of the lever,

serves to restrain the movement. of the latter in one directiomwhile permitting it to move in the opposite direction or away from said shoulder.

The lever 3 is maintained inA an upright position and against the stop or shoulder-8 by the yielding tension device 6, which may be constructed and applied as `follows: The head 9, which for `convenience is formed in two longitudinal sections, carries a vertical pin or guide 10, clamped or otherwise properly secured in an olset or projection 1l. A spring 12, encircling this pin, engages the oftset 11, while its outer or upper end bears against a cross-piece 13, fitted to slide on the pin 10 and connected t-o a yoke or stirrup 14, whose oppositeend or cross-bar engages a lip 15 on the head 9 below the oitset 11. The spring 12 is compressed between the oitset l1 and cross-piece 13, and serves to hold the lever against its stop S, at the same time permitting the lever to yield to pressure applied in a direction to force it away from said stop. The lever 3 is secured at its lower end by being clamped between the sections of the head or casting 9, and its upper port-ion is bent or curved rearwardly, substantially as shown, so*

that its outer or free end will be projected in a plane diagonal to the .plane of the axis or pivot 7, for a purpose to be explained. The slotted hook 14X or equivalent device for receiving and holding the check-row cord or wire, is pivotally attached to a collar or fer--v rule 15X, tted loosely, upon the lever 3, and said collar is provided with an offset or projection 1G for engaging a catch 17 on the head 9 ot' the lever when the collar is swung to one side, said catch serving to restrain the collar and prevent it traveling upon the lever until by the lateral motion of the hook the projection l0 is withdrawn from the catch.

The operation and mode of applying Vor usso as to slide freely ing the improved anchor are as follows: The

check row cord or wire is extended across the field, and one end is attached to the hook 14X, as by inserting one ot' the knots or protuberant portions between the jaws of the hook, the opposite end of the cord or wire being properly anchored at the opposite side ot' the iield. The anchor is employed as a lever to draw the cord or wire taut and place the requisite ten- IOO sion upon it, to which end the lever is inclined 'to advance the anchor-pin, and the point ot the latter is inserted in the ground, when,by straightening up the lever, the hook will be drawn back and the wire or cord stretched. The upper end of theleveris made to project rearwardly or Vaway from the cord, so that in setting the anchor (which is done by iirst drawing the cord taut, as explained, and then forcing the anchor-pin into the ground) it will be swung around with the handle in line with the cord or wire to insure the proper adjustment of the parts-that is to say, to bring the collar or ferrule to which the hook is secured in engagement with the catch 17 and to locate the pivot 7 at an angle to the cord or wire-so that the pla-ne of motion of the lever upon its pivot will intersect the ldirection of motion or line of travel of the planter upon its return trip. It will thus be seen that in the 'act of setting the anchor it is automatically adjusted to position, the pressure brought to bear upon the lever in drawing the cord or wire servin g to rotate the anchor until the lever is brought into line with the cord or Wire, when all the parts are in proper adjustment for operation. The anchor having been properly' located and secured in position,with the check-row cord or wire fast in the hook, the planter is advanced in a path parallel with the check-row cord or wire and in a direction away from the anchor, which serves to hold the cord or wire in opposition to the drag of the check-row mechanism operated thereby. Under ordinary circumstances the springwill be sufficient to prevent motion of the lever and hold the end of the cord or wire in fixed position, but will permit it to yield to a limited extent in case of obstruction in the passage seeding mechanism, thereby preventing sudden and violent shocks. It is during and near the termination of the movement of the planter in the opposite direction-that is, when approaching the anchorF-that the yielding of the point of attachment of the cord or wire is effected, so as to accommodate the new position of the planter and at the same time retain tension upon the cord or wire, and this is accomplished in the following manner: The return movement of the planter takes place on a line substantially parallel with its forward movement, but to one side of the anchor. The anchor having been set so that the plane of motion of the lever will intersect the path to` be traversed by the planter, as the latter approaches the anchor the collar 15X will be partially rotatedaboutthe lever and finally withdrawn from catch 17 by reason of the lateral deflection of the cord or wire attached to the hook. The continued approach of the planter brings the cord or wireinto the plane of motion ofthe lever upon its pivot, and the said lever is drawn forward or toward the planter against the resistance of the spring, thereby permitting the collar, with its attached hook, to ride up on the lever of the cord or wire through the.

and advance toward the planter, producing the effect 'of an elongation of the check-row cord or wire at its point of attachment to the anchor, thereby automatically accommodating said cord or wire to the changed position of the planter, without, however, entirely relaxing the tension. It is in this connect-ion that the curved form of thelever again comes into play to perform another and additional operation-that is to say, preventing the too sudden release of theNend of the cord or wire. If a straight bar or lever the collar to travel upon, it would have to be moved through but a short arc before the collar would, owing to increased leverage, draw the lever down to a horizontal position, thereby quickly eecting the extension and as rapidly diminishing the tension on the cord or wire; but by inclining or curving the upper were employed for portion of the lever backward or away from 1 the planter the collar is' prevented from racing toward the end of the lever, and is drawn gradually out toward the planter as the latter approaches, thereby maintaining the tension on the check-row cord or wire and permitting the team to come up to and partly pass the anchor, as though the wire or cord lay in a straight line ahead of the planter.

It is obvious that a straightbar or lever may be employed in place of the curved lever to serve as a guide for the hook, though it will not possess allthe advantages ot' the curved form.

In Fig. 3 the straight, form'of lever is shown.
