SPECIFICATION forming part of Letters Patent No. 609,492, dated August 23, 1898. Application fled May 11l 1897. Serial No. 636,116. (No model.)

To all whom t muy concern:

Be it known t-hat I, AXEL F. BERGQVIST, a citizen of the United States, residing at Fairfield, in the county of Jefferson and State of Iowa, have invented certain new and useful Improvements in Plows, of which the following is a specification.

This invention relates to certain new and useful improvements in sulky-plows; and it consists, substantially, in such features of construction,arrangement, and combinations of parts as will hereinafter be more particularly described.

The invention has for its object to provide simple and effective devices for raising and lowering the plow-beam, by which to adjust the plow, and also to provide means for readily effecting the lateral or sidewise adjustment of said plow-beam. These and other objects I attain by the means illustrated in the accompanying drawings, in which;

Figures 1, 2, and 3 each represents a perspective view of my improved sulky-plow, the said views being taken from different positions, by which to better illustrate the general construction and disposition of parts. Figs. 4, 5, and 6 are views in detail o f certain .parts which will be more specifically referred to hereinafter.

My invention is capable of a great many different embodiments, and while the present construction and arrangement could be varied in many immaterial respects I prefer to use the same on account of the many advantages which I have derived therefrom in actual practice. Thus a represents the main axle of the plow, which at one `end is bent at b slightly to the rear, and thence outward at substantially right angles to constitute a jour-` nal or spindle c for the large wheel d, located on the landside of the plow, the said wheel being mounted in place upon said spindle in the usual or any well-known way. The opposite end of the said axle is also similarly bent at c and f, respectively, and the journal or spindle j has its bearing in a box or collar g, formed on the inner side of an upright or vertically-disposed sleeve or casting h, which is of a height to extend both above and below the main axle a a suitable distance and which constitutes a support or bearing for a vertical rod or shaft z, having its lower end bent outward substantially at right angles to constitute a short axle j for the front furrowwheel 7a, which latter is of smaller size or diameter than the wheel d on the landside. The lower end of the sleeve or casting hrests upon a collar Z, securely fixed to the vertical shaft i at the proper point. Fittedupon the upper end of the vertical rod or shaft 1) is a tubularCasting or sleeve n, with which is formed a forwardly-projecting bracket e" and a short tubular bearing o, through which latter passes a pin p, and said pin also passes through tubular lugs q, formed on the inner end of a tongue-plate fr', Fig. 5, said lugs being separated by a recess s in the plate for receiving or accommodating the tubular bearing-lug o in such manner as to constitute a very desirable means for attaching or securing `the tonguefplate in position. As the sleeve n is keyed or otherwise secured to the I shaft c', it is evident that the said shaft will turnwith the tongue-plate as the tongue of the plow is moved from side to side. On top of the main axle a is a frame t, which extends lengthwise of the axle and consists of a single piece or casting made concave on its under side to receive the axle and which is provided at dierent points with-opposite perforated lugs u. Said frame is fastened in place upon the shaft by means of a staple u and clamping-plates e and bolts w, which latter pass through both the lugs u and the said plates and are properly secured by nuts or otherwise.

The plow-beam is shown at A, and the same is curved slightly downward and forward at its forward end and is also curved downward at its rear end, the plow B being secured to the rear end in any suitable or preferred way. It is desirable to provide for the raising and lowering of the said beam to adj ust the plow and also to change or adjust the position of the beam laterally by which to effect the sidewise adjustments of the plow, and while these operations could be effected in different ways I prefer the several means which I have herein shown for the purpose. Thus the said beam rests at near its forward end upon a saddle B', that is flat on top and provided with side por tions l, which embrace the sides of the frame t, and said saddle is provided with a vertical lug 2, which lies against one side of the beam,

IOO

and a bolt 3 passes through the lug and beam by which to secure the latter in place. A bolt 4 passes through the side portions 1 of the saddle and likewise through the opening in the rib ne on the upper surface of the frame, and in this way the saddle can be tilted laterally to effect the sidewise adjustments of the beam and plow. In order to regulate and limit the said lateral adjustments, the saddle is provided at each end with a vertical screwbolt 5, each of which rests at its lower end on the upper surface of the frame, and it will be seen that by properly turning said bolts the saddle and beam can be tilted to one side or the other and held to such position. Secured to the upper surface of the saddle is an angie-plate 6, between which and the lug 2, already referred to, the said beam is secured in place. It is further desirable in this class of inventions that the trail-wheel, such as is indicated at 8, be caused to follow in a straight line while the plow is moving straight, and also that the saine shall follow the plow properly in turning in either direction, and this I effect as follows:

To the rearward curved portionof the plowbeam A is attached or secured a casting C, which is formed with projections 9 10, that are provided with openings and separated by a space or opening 11, in which is received a movable box or swivel 1-2, the said box or swivel being provided with a bracket 13, projecting rearwardly of the beam and also having a depression or V-shaped recess 14 at its upper portion, or, if desired, said depression could be formed in the upper surface of the Passing through the said projections 9 10 and the box or swivel 12 is a @levis-pin 15, which is provided with a spring 16, exerting a tension to normally draw the pin downward, and tting beneath the head of the pin or a short cross-pin 17, passing therethrough, is a locking device or plate 18,

l resting on top of the casting beneath the crosspin 17 and having the outer end thereof turned or bent downward and tapered or pointed at 2O to enter the V-shaped depression referred to. The end of the bracket 13 is provided with a sleeve or bearing 2l, in which is received the bent end 22 of an arm 23, which at' its other end is bent at 24 to form a short axle If desired, the outer end of the said arm may also be so turned or bent at right angles as to constitute the axle for said wheel.

From the construction and arrangement shown it is evident that while the plow is moving forwardly in a substantially straight direction the trail-wheel will also travel straight and the tapered end of the lockingplate will be confined between the sides ofthe V-shaped depression or recess in such manner that the said trail-wheel is not liable to be diverted in either direction. When,

however, the plow is turned, the swivel-pin acts substantially as the turning-point or pivot, and in virtue of the forced tendency of the trail-wheel to follow in the same direction the swivel or box 12 will turn on the swivel-pin, and the side of the recess or depression 14, engaging the side of the tapered end of the locking plate, will cause the pin to yield upwardly against the tension of its sprin g, thus permitting the trail-wheel to follow the proper direction of the plow. As soon as the plow begins again to move in a substantially straight line the former position of the parts will be resumed. It is obvious that other equivalent locking means could be employed in connection with the trail-wheel and still be within the scope of my invention.

Secured to the beam A on the side adjacent to the furrow-wheel is a segmental rack 30, and pivoted to said beam on the same side and at a point about centrally intermediate the ends of the rack-as, forinstance,on abolt 31-is the main operating-lever D, through the medium of which the devices for raising and lowering the axle and beam are operated. A casing or guide 32 is secured to the side of said lever and in which moves or works a vertically-operatin g bolt 33 for automatically engaging the teeth of said rack. The said bolt 33 is provided with a plate 35, having an eye 36, in which is fastened the lower end of a rod 37, the upper end of which is in movable connection with an arm of a curved supplemental lever D', that is pivoted to the side of the said main leverD at near the upper end of the latter. A pin 33 also constitutes practically a part of the bolt, and it passes through an opening in a plate 39 on the side of the main lever and is provided with a spring 40, bearing between said plate 39 and the plate 35, with a tendency to maintain the bolt in engagement with the rack. By grasping the upper ends of the main and supplemental levers and exerting pressure sufficient to swing the lower arm of the latter outward the said bolt will be released.

The lower end of the main vlever is in movable connection with a link-lever 43 to a short upright lever 4l, pivoted on the side of the beam (the pivot thereof being the bolt 42, which secures one end of the rack to the beam) through the medium of a connecting-link 43, and at a point above its pivot the said main lever is also in movable connection with an upright lever or arm 45, mounted rigidly on the main axle ct. Said latter movable connection could be effected in different ways, but preferably by means of a straight bar 46, pivoted at its rear end to the side of the main lever and having its forward end crooked and engaging the said upright arm 45 on the axle. It is evident that by releasing the bolt from engagement with the rack and pushing the main lever forward the axle a will be carried forward and downward, and the rear end of the beam will adapt itself also downward, so as to be carried on hind wheel or trailer when plow is lowered in furrow. By pulling the main lever backward, however, the reverse will be the effect.

' of the said axle.

As an auxiliary device to assist and render more easy the operation of the means for adjusting the beam I employ a pivoted hook 47, that is pivoted or mounted on the pivot of the main lever, the same having its rearward arm fitted upon the pivot 42 of the upright lever 4l, while the forward end has a hook to receive spring 50, the opposite end of said spring being fastened to lever or upright arm 45 by hook from spiral spring 50.

The main purpose of the upright short lever 4l and the link 43, connecting the same with the short arm or lower end of the main lever D, is to always maintain the upright shaft/in a perpendicular position in whatever position the beam and the main axle Vct may be, and also for making up for the loss and gain of the upward-and-downward movement These results are accomplished by connecting vwith the upright lever 41 on the furrow side, at a point'beneath its pivot, the rear end of a rod 55, which extends forward and by right-angled turn at the forward end passes through an eye or hollow projection 5G, cast on the front side of the hollow vertical sleeve or casting h, through which the vertical shaft t passes. could be resorted to for the same purpose, but these are preferred on account of their sim plicity and effectiveness.

The plow-seat 57is mounted upon the upper end of a curved spring-plate 58, the lower end of whichis secured to a substantially horizontal V-shaped iron or frame 59 by means of a clamp and bolt 60, the said iron or frame 59 being secured to the beam A on the landside and at right angles thereto, said means of supporting the seat being extremely simple, strong, and advantageous.

A brace-rod 65 is attached at one end to the landside of the beam by an eyebolt, being the same bolt that passes through the beam and main lever. The purpose of this eyebolt is to enable the brace-rod to have a sort of swivel action, while at the same time bracing the plow. Said rod at its other end enters a hollow casting 67, formed with the axle-frame at the end thereof adjacent the landsidewheel.

Adjustably supported at the forward end of the the beam is the clevis-plate 68, which is engaged and held in position by means of a hook on a rod 69, pivoted on the side of the beam.

Bolted to the top of the frame t by the same bolts which secure the beam to saddle is a footboard 70, on which the operator rests his feet while seated upon the plow.

As before stated, I am at liberty to make immaterial changes in the general construction and arrangement of parts, and therefore, without limiting myself to the precise details shown and described,
