.To all 'whom it may concern:

Be it known that I, WILLIAM L. PAUL, of South Bend, in the county of St. Joseph and State ot' Indiana, have invented certain new and useful Improvements in Sulky-Plows; and I do hereby declare the4 following to be a full, clear, and exacty description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in sulky-plows, and more-particularly to means for raising the plows, one object ot' the invention being to provide simple and efficient appliances to facilitate the raising of the plows either manually or by power applied by the draft animals, and to provide devices lwhereby t-he power lifting means can be thrown into action. by the operator either with'lns hand orwith his oot.

WVith these objects in view the invention c consists in various novel features of construct-ion and combinations of parts as hereinafter set forth and pointed out in the claims. f

In the accompanying drawings, Figure 1 is'a side elevation of a plow`showing my improvements. Fig. 2 is a sectional view,

Fig. 3 is an end view partly in section, and Litis. a perspective view illustrating .my improvements.

1 represents the iframe` of a sulky plow and 2 the carrying wheels. The axle ot' the machine comprises two hails 3, 3, each provided at its outer end with a. journal for the accommodation of a carrying wheel. Each vbail 3 is provided at its inner end with an arm ll and the arms 4t ot the respective .hails are pivotally connected with a depending portion, 5 located .centrally between the sides of the 'frame 1. Plow beams 6 are mounted between their ends upon the respectiveA bailaxleesections and provided at their rear ends with plow bottoms in the usual manner.

At each side of the frame 1, an operating lever 8 is located and pivotally supported at 9 by depending portions of the Jframe. The lower end of each operating le-.rer is'con- .nected with one of the axle bails and sei. lt is apparent. that'when one of these .levers is moved by the operator, the bail with which t-he lever is connected will be' turned'and theplow connected with this bail will raised or lowered. In order to insure the proper operation of the axle bails without danger of binding or straining the pivotal supports, an arm' 10 is rigidly secured at one end to each bail and at the Iother end pivotally connected with the frame approximately in horizontal alinement with the pivotal support of the operating levers and the inner ends of the bails.

Segments 1l are mounted on the frame 1 at respective sides thereof and each of these segments is provided on its under side or edge with teeth to be engaged by a lug 12 on a locking bar 13 carried by the operat ing lever. This locking bar` is normally pressed upwardly to insure the engagement of the lug 12 with the teeth of the segment 11 by means of a spring 14. vWhen the plow isV to be raised by hand the locking bar twill be moved downwardly so as to disengage the lug 12 from the tooth segment 11 and this can be readily' accomplished by `means of a latch-lever 15 pivotally attached to the operating lever and provided at one side of its pivotal support with an elongated slot 1G to receive a` pin 17 projecting' Jfrom the locking-bar.. It is apparent that Aby pressing the latch-lever toward the operatH ing lever, the locking bar will be slid down- 'wardly against. the resistance of the spring 14C and the lug 12 will'be disengaged from the toothed segment.

Eachy carrying wheel has secured to its hub a ratchet or clutch wheel 18 and each operating lever is provided with a curved flange or hood k19 overhanging the clutch wheel. Each curved ange or hood 19 provided with an opening 20 for the passage ,of the lower end ot the locking bar 1.3 so

`that the latter can be moved downwardly to engage the clutch or ratchet wheel. This downward movement of the locking-bar may be .accomplished by means of a'latch lever 21 pivoted to the operating lever preferably at a point below the latch lever 15 and pro-v vided with a slot 22 to receive a pin 23 on ,the locking bar. When the locking bar has been thus moved downwardly so as to engage the clutch or ratchet wheel, the for ward movement of the draft animals and the consequent turning of the carrying wheel willcausemotion to be transmitted through the ratchet or clutch wheel, the locking-bar' and the operating lever, to the aXle bail with which the operating lever is connected and the turning of this bail will effect the raiswhereby the devices which effect the raising of the plows can be controlled through the medium of foot levers. AThese devices will now be described. Two foot levers 24, 24, are mounted in suitable brackets depending from the forward portion of the frame 1 at the sides of the latter and in a bracket 26 located intermediate the sides of the frame. A bell-crank lever 27 is pivotally attached to each operating lever 8 at a point in proximity to the pivotal support ofithe latter. Une arm of this bell-crank lever is connected by means of a link 28 with the locking-bar 13 carried by the operating lever. To the other arm of the bell-crank lever 27, one end of a rod or link 29 is pivotally attached and the other .end of said rod or link is provided with an elongated slot 30 to receive the end of a crank arm 31 on the adjacent foot lever 24. By reason of the play a'orded by the slot 30, the operator can move the locking bar by hand without also moving the foot lever.

From the construction and larrangement of parts above described it will be seen that when the operator moves a foot lever 24 forwardly, the rod orlink 29 will also be moved fforwardly and motion will be transmitted through the bell-crank lever 27 and the link 28 to the locking-bar so as to cause the latter to descend and engage. the ratchet or clutch wheel on the adjacent carrying wheel. The forward motion of the machine vwill now cause the operating lever to be turned and the axle bail with which it is connected to be also turned and'lhe plow to be raised. As f the operating lever moves forwardly,l a lug 32 on the locking bar 13 will engage a cam or shoulder 33 on the top -of the segment 11 when the 'plow shall have been suiciently raised, and thus cause the locking-bar to be elevated out of engagement with the ratchet or clutch wheel, when the carrying wheel to which this clutch wheel is secured can run freely. The locking bar 13 will now -be caused, by the action of the spring 14, to-

engage a tooth of the segment 11. The foot levers are maintained in their normal positionby means of springs 84 attached at one end to said levers and at the other end to the frame 1. The springstandard 36 for ahseat 37 is attached to the frame'of the mac ine.-
