PLOW.

SPECIFICATION forming part of Letters Patent No. 781,155, dated. January 31, 1905.

v Application filed May 9, 1903. Serial No. 156,441.

To all whom, it may concern:

Be it known that I, WILLIAM L. PAUL, a citizen of the United States, residing at Bradley, in the county of Kankakee and State of Illinois, have invented certain new and useful improve ments in Plows, of which the following is a specification, reference being had to the accompanying drawings.

' lVIy invention relates to plows; and its object is to provide new and improved devices by means of which the plow may be more efficiently landedthat is to say, may be caused to take more land or less land and cut a wider or a narrower furrow, as may be desired.

In the accompanying drawings, Figure 1 is a top or plan view. Fig. 2 is a side elevation with one wheel removed, showing the axle in cross-section; and Fig. 3 is an enlarged detail showing in plan a portion of the plow-beam,

a portion of the axle, and the shifting devices in two positions, one in solid and the other in dotted lines.

Referring to the drawings, 4 indicates carryin'g-wheels which are mounted upon an axle 5. The axle 5 is provided with bent ends or portions 6,whioh are constructed in any wellknown and approved manner and operated by any well-known form of levers and accompanying devices to raise and lower the plow. As this feature may be of any well-known and approved form and manner of operation and forms no part of my present invention, it is believed it is unnecessary to describe it more fully here.

7 indicates a plow-beam upon which the plow 8 is mounted in the usual manner.

9 indicates a caster-wheel pivotally connected with the plow-beam 7 and operating in any well-known and approved manner.

10 indicates a turn-table on which the axle 5 is pivoted, so as to swing laterally about the pivotal point 11. The turn-table 10 is provided with a lip 12, by means of which it is bolted or otherwise secured to the plowbeam 7 13 indicates a bracket which is preferably formed integral with the turn-table and which serves as a support for a seat-bar 14, which is bolted or otherwise secured therein and carries at itsup'per end seat 15.

16 indicates a segmental rack which is secured to the axle 5, as is best shown in Fig. 2.

17 indicates a hand-lever which is pivotally connected at its lower end to the segmental rack 16 and is provided with the dog 18, spring 19, bell-crank lever 20, and connecting-bar 21, whereby when the dog 18 is withdrawn from engagement with the segmental rack 16 the lever 20 may be rocked and when the bellcrank lever 20 is released the dog, again engaging the segmental rack,will operate to hold the lever in the desired position. The dog and devices for operating the same may be of any well-known and approved character.

22 indicates a clevis which is provided with a number of openings 23, in any one of which the doubletree 24 may be mounted. The clevis 22 is pivoted in a support 25, which is bolted otherwise secured to the forward end of the plow-beam 7. The support 25 is providedwith several openings 26, adapted to receive a bolt 27, by means of which the clevis 22 is pivotally connected with the support 25. The clevis 22 is provided with an arm 28, which is preferably of the form shown in Figs. 1 and 3 and which extends laterally to one side of the line of draft, passing through the pivotal point of the clevis.

29 indicates alink. The rear end of the link 29 is pivotally connected with a lug 30, which is preferably formed integral with the segmental rack 16, as is best shown in Fig. 2, but may be of course formed upon or secured to the axle 5. The forward end of the link 29 is screw-threaded and passes through an interiorlyscrew-threaded sleeve 31, which is pivotally connected with the end of the arm 28 of the clevis 22. The link 29 passes under the plow-beam and crosses over the line'of the samethat is to say, the arm 28 extending laterally to the left of the plow-beam, the link 29 extends diagonally across and is connected with the axle upon the right of the plow-beam, whereby when the axle is rocked, as hereinafter described, the clevis will be rocked in an opposite direction, as is shown in dotted lines on Fig. 3. In other words, if

on the screwthreaded portion of the link 29 to the desired position, when it may be again connected with the arm 28.

32 indicates a link the rear end of which is pivotally connected with the lever 17 above its pivotal point and the forward end of which is bent downward and passes through a suit-' able opening in the support 25.

It will be obvious from the above description that when the lever 17 is thrown backward, the distance between the lever and the support 25 being fixed by means of the link 32, the right-hand side of the axle 5 will be thrown forward, carrying with it, of course, the segmental rack 16, and the. entire axle will be rocked toward the left in the position shown by dotted lines in Fig. 3. At the same time as the portion of the axle to the right of the pivot 11 moves forward the link 29 is carried forward with it and, throwing the laterally-projecting arm 28 forward, rocks the clevis 22 to the right into the position shown in Fig. 3. The amount of this rocking motion is exaggerated in dotted lines in Fig. 3 for the purpose of clearness of illustration. When the lever 17, however, is thrown forward, precisely the reverse will occurthat is to say, the portion of the axle to the right of the pivot 11 Will be moved backward, rocking the axle to the right and correspondingly rocking the clevis to the left. The draft being applied through the doubletree 24 and the clevis 25, it will be obvious that when the lever is thrown backward and the axle rocked to the left and the clevis to the right the effect of the draft still pulling in a straight line will cause the plow to take more land and cut a wider furrow, and the amount of additional land so taken. will be the combined result both of the rocking of the axle and the swinging or rocking of the clevis. If the clevis remained unmoved, the rocking of the axle to the left would cause a certain amount of more land to be taken. If the axle remained in its original position at right angles to the draft and the clevis were rocked to the right, the effect of this alone would also be that the draft would cause the plow to take additional land. When the two actions are combined, which is the object and essence of my invention, a much less rocking of each will cause the plow to take the desired additional amount of land than could be effected if only one were rocked. The parts are thus much more readily operated, and the plow may be caused to take more or less land by the combined operation of the two devices.

I have described the member 22 as a clevis, and that is the form, of course, in which I prefer to embody this feature of my invention. By the use of the word clevis, however, it is not to be understood thatI restrict myself to a clevis technically so called, as some other form of a lever which might not be within the technical definition of the word clevisff but which would operate in substantially the same manner and was capable of being rocked in the same manner and connected with the draft, will perform the same function as a clevis, so called. I therefore in using the word clevis intend to use it for purpose of convenience of description and as describing the preferred form of this device and as covering any other form of lever which could perform substantially the same functions with reference to the assisting in the landing of the plow.

The form in which I have embodied my invention as above described is the form in which I have preferred to construct it and the several parts, I do not, however, confine myself to the specific form of devices shown, and it is obvious that the form of such devices and the precise form and manner of the actions might be modified without departing from the spirit of my invention.

That which I claim as my invention, and desire to secure by Letters Patent, is

1. In a plow, the combination with a plowbeam, an axle pivotally connected with said plowbeam, and carrying-wheels mounted on said axle, of a clevis pivotally mounted on said axle and means for simultaneously rocking said plow-beam and said clevis on their respective pivotal supports in opposite directions, substantially as described.
