PLOW RIDING ATTACHMENT.

SPECIFICATION forming part of Letters Patent N0. 488,848, dated December 2'7, 1892.

Application filed May 14, 1891. $erial No. 392,792. (No model.) Patented in Canada December 9, 1891, No. 37,933-

To all whom it may concern:

Be it known that 1, WILLIAM E. STAFFORD, a citizen of Canada, residing at the village of Shedden, in the county of Elgin,in the Province of Ontario and the Dominion of Canada, have invented a new and useful Plow Riding Attachment, of which the following is a specification, and for which I have obtained Letters Patent No. 37,933, dated December 9, 1891, in the Dominion of Canada.

This invention relates to an improvement in sulky plows or riding attachments and among other things it has for its object to provide a vertically and laterally adjustable gage wheel for regulating the width of a furrow; to provide means for raising and lowering the supporting and turning wheels; to provide a frame for supporting the various parts which will be of a cheap and durable construction; to adjust the drivers seat vertically and laterally upon the frame; to adapt the hand lever for raising and lowering the wheels to be operated from either side of the drivers seat, to afford a quick and ready means for attaching and detaching a walking plow to the main frame wherebya walking plow may be readily converted into a riding or sulky plow.

Other objects and advantages will appear from the following description and claims when taken in connection with the annexed drawings in which:

Figure 1, is a perspective View of my improved machine. Fig.2, is a plan view of the same with the walking plow attached. Fig. 3, is a perspective view of the turning wheel, and its attachments with the main frame and transverse rock shaft partly broken away. Fig. 4, is a perspective of the vertically movable bar for supporting the main wheel showing the trunnion and main frame partly broken away. Fig. 5, is a front view of the gage wheel and its attachments showing the slide bearing with the main frame and connecting rod partly broken away. Fig. 6, is a plan view of the guide for the main wheel bearing bar showing the rock shaft partly broken away and its bearing in section. and: Fig. 7, is a plan view of the box or guide bearing for the movable bar supporting the turning wheel.

Referring by letters and numerals to said drawings: A, indicates the main frame. This frame is preferably composed of a single piece of material such as stout bar iron bent into a rectangular form as shown and having its lateral terminal branch bent downwardly in a vertical manner as shown at a, while its other end terminates in the forward transverse branch 17, and this frame is braced at one of its angles by means of an angular brace B, which is composed of bar iron and adapted to serve the additional function of a foot rest for the driver when arranged in front of the drivers seat, and secured in position by bolts and nuts or other suitable fastening devices.

Secured in a vertical position and on the outer side of the depending terminal branch at, of the main frame is a guide casting or box 0, which is of a formin cross section substantially as shown in Fig. 7, of drawings, having flanges c, to embrace the opposite edges of the branch a,and a channel d,on its outer side to receive and guide the standard or bar D,. This bar D, carries a trunnion or spindle e, on its outer lower side to recive the turning wheel E, which is journaled thereon. This bar is straight and assumes a vertical position for the greater portion of its length,

where it is guided in the channel d, in the box. or casting O, and above its straight portion is bent rearwardly and thence vertically as atf, where it is provided with a series of transverse. holes g, for a purpose which will be presently described.

F, indicates an angular lever comprising a branch h, and another branch 1,. This angular lever is pivoted at its angle upon a bolt It, on the inner side of the terminal branch a, of the main frame, and said lever has an eye at the outer end of each branch; the branch It, being connected by means of a rod G, with an arm secured to the rockshaft H, as will be hereinafter more fully described and the outer end of the branch '6, is connected by means of a rod I, in one of the transverse apertures g, of the vertical branch f, of the upright bar D, whereby through the medium of a hand lever and the rocking of the shaft H, the turn wheel E, may be raised or lowered in its sliding box or hearing, and by the series of perforations g, the connection between the angular lever F, and said sliding upright may be made adjustable. The rock shaft H, which is transversely disposed and preferably of an angular form in cross section is journaled in bearings at the rear upper side of the main frame; a bearing arm K, being clipped to the rear transverse part of the main frame at one end by means of bolts and nuts, and the bearing M, for the opposite end of the rock shaft may be formed integral with the guide box or casting Z, at the opposite side of the frame as better shown in Fig. 4, of the drawings.

N, indicates an upright similar to the up right d, atthe opposite side of the frame having a straight portion m, movable in the channel n, of the box or casting Z, which is secured to the main frame by bolts or the like, and also has the rearwardly bent portion p, and the vertically disposed branch q, proyided with perforations r,.

P, indicates an arm which is keyed on one end of the rock shaft H, and extends rearwardly. This arm is connected by means of a link or rod Q, at its lower end and the opposite end of the rod is adjustably securedin the perforations of the branch q, of the up right N,whereby a rocking of the shaft H,will tend through the medium of this arm and connecting rod to raise and lower the main wheel S, with respect to the frame.

T, indicates a depending rod which is bent so as to hang free within the frame and have its lower end terminating in an inward branch to form a step 8, and its upper end is secured in the upright N, as shown so as to serve as a convenient means for the driver to mount.

U, indicates the gage wheel which is hung on the transverse forward branch of the main frame and is designed to travel on the land side so as to regulate the width of the furrow. This gage wheel is designed to be both vertically and laterally adjustable.

V, indicates a slide. This slide is arranged upon the forward transverse bar of the main frame, and has secured to it a rearwardly and downwardly directed segmental rack 25,.

V, indicates a hand lever. This hand lever is provided at its lower end with an angular branch u, and is pivoted at its angle to a depending integral or fixed branch 10, of the slide V, so that said lever may have a move ment along one side of the rack t,; a spring pressed bolt 0:, beingarranged to engage the teeth of the rack and connected by means of a rod 11, with a finger lever z, pivoted to'said hand lever Vt, near its grasping portion so that said lever may be locked in any desired tooth of the rack by manipulating the finger lever z, and the gage wheel U, is journaled on the lower end of the angular branch to, so that by moving the hand lever W', on the pivot, said wheel will be correspondingly moved and raised or lowered from the ground as the case may be.

X, indicates a bell crank lever. This lever is pivoted at its angle upon a stud or shank Y, which is in turn clipped to the main frame by bolts and nuts or the like.

The numeral 1, indicates a segmental rack having a vertical stem 2, which is secured to one side of the main frame by bolts or otherwise.

3indicates a hand lever which is pivoted near its lower end to one side of the segmental ra ck l, and its lower end is connected by means of a rod 4, with one branch of abell crank lever. The opposite branch of said lever being connected by means of a transverse rod 5, with the slide V,. This hand lever also carries a spring pressed bolt 6, for entering the teeth of the segmental rack 1, so as to fix said lever thereto at any desired position and this bolt is connected by means of a rod 7, with the angular end of a pivoted finger lever 8, arranged at the grasp of the lever 3,. By this construction, it will be seen that the driver may conveniently adjust the gage wheel laterally by simply manipulating the hand lever 3, while by means of the hand lever WV, he may raise the gage wheel entirely from the ground or adjust it at any desired altitude.

10, indicates a brace rod which extends from the front branch of the main frame to the bolt 7e, on the depending terminal branch a, of said frame so as to properly brace the same. i

11, indicates the drivers seat. This seat which is mounted on a bar 12, is clipped to the rear transverse bar of the main frame by yokes 13, and bolts 14, so that the seat may be shifted laterally on the frame, as well as raised or lowered by simply loosening and tightening the bolts on the yokes.

15, indicates a vertically disposed segmental rack. This rack is clipped to the main frame by clips 16, and said rack has an eye 17, through which the rock shaft passes, and the rock shaft at the point where it passes through the eye in the segmental rack has keyed to it a round bearing 18-whereby the said shaft may be allowed to rock within the rack.

19indicates a hand lever. This hand-lever is keyed at one end to the rock shaft so as to turn the same, and is adapted to be shifted upon the rock shaft, so that it may be placed at either side of the drivers seat; the segmental rack 15, of course being shifted to the point wherever the lever is arranged so as to co-operate therewith as will presently appear. This hand lever 19, also carries a spring pressed bolt 20, to enter between the teeth of IIO the rack 15, and has a thumb lever 2l-connected with said bolt by means of a rod 22. By the manipulation of this hand lever bolt the main wheel and the turning wheel are adjusted with respect to the main frame and by reason of said lever being readily shifted along the rock shaft, it affords of manipulation by either the right or left hand of the driver and this will be found very desirable when the driver has but one hand.

23, indicates a walking plow which may be of any ordinary or approved construction. This plow is clipped substantially to the forward and rear transverse branches of the main frame. The forward clip may be composed of two hooked branches 24, embracing the main frame, and a plate 25, passing under the forward end of the plow beam and nuts for securing said plate in position. The rear clipping or attaching devices preferably comprise a casting 26, having a transverse eye and two side plates 27, arranged at opposite sides of the rear portion of the plow beam and having corresponding eyes at one end to receive the pivot connecting bolt 28, which lies above the beam and the opposite ends of said side plates are connected by means of a bolt 29, beneath said beam. The plow is thus secured rigidly to the frame, and any pitch which may be desired is secured by manipulating the hand levers so as to raise or lower the wheels.

30, indicates the draft beam. This beam may be connected with the main frame by means of a brace 31, and may be pivotally connected to the forward end of the plow beam by means of a bracket or casting 32, although in some cases this draft beam might be omitted and the draft connected directly to the forward end of the plow beam in the usual manner. 7
