CONNECTING-ARCH FOR CULTIVATORS.
SPECIFICATION forming part of Letters Patent No. 767,251, dated August 9, 1904.
Application filed June 16, 1904. Serial No. 212,793. (No modelfi To It whom, it may concern:
Beit known that I, ERNEST SonULz, a citizen of the United States, residing at Roundrock, in the county of Villiamson and State of Texas, have invented a new and useful Connecting- Arch for Cultivators, of which the following is a specification. 7
This invention relates to riding-cnltivators of that class in which two separate cultivator gangs or rigs are employed, as is usually the case in riding-cultivators. The invention has for its object to enable the said gangs or rigs to be efficiently and conveniently controlled by the operator, more especially with regard to the spacing apart of said gangs, which by my invention is made entirely within the control of the operator.
Specifically, the invention consists in an improved so-called arch whereby the cultivator-gangs are connected, said arch consisting of separate members suitably connected with each other and with the cultivator-gangs and means whereby the lower ends of said members may be adjusted with relation to each other for the purpose of effecting the desired relative adjustment of the cultivator-gangs.
W ith these and other ends in view which will readily appear as the invention is better understood the same consists in the improved construction and novel arrangement and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.
In the accompanying drawings, Figure 1 is a rear elevation of an ordinary type of ridingcultivator, showing my invention connected therewith. Fig. 2 is arear elevation. enlarged,
vided with a segment-rack 4:. The upper ends of the members 1 2 are connected by means of a transverse bolt 5, and a connectinglinkfi, which is pivotally connected with the member 1, has a bifurcated outer end for the reception of the limb or member 2. Said bifurcated end .of the link is provided with a transverse slot 7 for the reception of a pin 8, which eX- tends through the member 2, thereby limiting the movement of the latter within thelirnits of the ends of the slot 7.
9 designates an operating-lever which is provided with an approximately circular-head 10,
- having a central opening for the connecting bolt 5, upon which it is mounted pivotally between the members 1 and 2, constituting the arch. The head 10, the narrow portion of which is disposed adjacent to the=lever- 9, from which the thickness of the rim of said head increases in opposite directions, as clearly shown in Fig. 4 of the drawings, thus forms what may be termed a double cam, the wide ends of'which are separated by recesses 11 in opposite sides of the disk or head. The lever 9 is provided with a spring-actuated dog 12, engaging the rack-bar 4:, whereby the said lever may be maintained securely at any desired adjustment.
The operating-rod 13 of the dog 12 is provided in its upper end with a handle 14:, which lies closely adjacent to the handle 15 of the lever 9, so that it may be readily grasped when the handle of the lever is grasped for the purpose of adjusting the same.
The lower ends of the members 1 and 2 have been shown as being provided with hooks 16, whereby convenient connection may be made with staples or eyes 17, provided for their reception upon the cultivator-gangs.
The operation of this device will be readily understood. WVhen it has been mounted in position upon the cultivator, the driver may by manipulating the lever 9 adjust the Wide portions of the cam-head between the members 1 and 2 either above or below the connecting-bolt 5. 1f the wide portion of the cam is placed between the side members 1 2 above the connecting-bolt, it is obvious that the lower ends of said members are forced in the direction of each other, thus lessening the distance between the rigs or gangs of the cultivator. hen, on the other hand, the wide portion of the cam-head is placed between the members 1 and 2 below the connecting-bolt 5, the lower ends of said members will be spread apart, thus increasing the distance between the cultivator-gangs. The link connection 6 serves to maintain the relative position of the members 1 and 2 and to prevent displacement.
If for any reason it shall be desired to permit the gangs to have free play with relation to each other, the operating-lever may simply be turned upon its fulcrum until the recesses 11 are in alinement with the members 1 and 2, when the cam not being interposed to space them apart the lower ends of said members 1 and 2 are capable of free play with relation to each other.
The improved adjusting device, as will be seen from the foregoing description, is extremely simple in construction and may be produced at a moderate expense. It is readily applicable to any ordinary cultivator and will enable the operator to have complete control over the implement.
Having thus described the invention, what is claimed is 1. A cultivator-arch includingapair of side members, a bolt connecting said side members near their upper ends, and a cam-disk mounted for rotation upon said bolt between the side members.
2. Acultivator-archincludinga pair of side members, a bolt connecting said side members near their upper ends, a cam-diskmounted for rotation upon said bolt, alever connected with the cam-disk, and means for maintaining the latter in adjusted position.
3. A cultivator-arch including a pair of side members having upward straight extensions, a bolt connecting the latter, a rack-segment upon one of said extensions, a cam-disk mounted for rotation upon the bolt between the extensions of the arch members, and a lever connected with said disk and carrying a springactuated dog engaging the rack-segment.
4. A cultivator including a pair of side members having straight extensions, a link pivototally :connected with one of said members and having a bifurcated end for the reception of the other member and a transverse slot in said bifurcated end, a pin extending through said slot and through the member engaging the bifurcated end of the link, a bolt connecting the upper ends of the side members, a cam-disk mounted for rotation upon said bolt between the side members, and means for securing said cam-disk in adjusted position.
5. A cultivator-arch including two members loosely connected together near their upper ends, a cam-disk mounted for rotation between the upper ends of said side members, and means for manipulating and for securing the cam-disk at various adjustments.
6. A cultivator-arch including a pairofside members loosely connected near their upper ends, a link forming an auxiliary connection for said side members, a cam-disk mounted for rotation between said side members near their upper ends, said disk having an operating-lever and cams increasing in width from said leverin the direction of the opposite edge of the disk, and recesses between the wide ends of said cam, and means for retaining said disk at various adjustments.
In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two witnesses.
