SPECIFICATION forming part of Letters Patent N 0. 706,825, dated August 12, 1902. Application filed January 6, 1902. Serial No. 88,644. (No model.)

To all whom it aw/y concern:

Be itknown thatLWILFORD I-I. HoLsoLAw, a citizen of the United States,residing at Louis ville, in the county of Jefferson and State of Kentucky, have invented certain new and use ful Improvements in Attachmentsfor Flows; and I do hereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to which it appertains to make and usethe same. 1

This invention relates to improvements in plows, and more particularly to'attachments designed to be applied to a walking-plow to transform the same into a ridingplow or sulky.

One objectin view is the production of such an attachment designed to be readily applied to any of the common forms of walking-plows and capable of being adjusted to control the depth of furrow; and a further object is the production, in connection with such attacl1- ing means, of means for facilitating the ready adjustment of the traction or carrying wheels to a wide or narrow gage.

l/Vith these and other objects in view the invention consists, in combination with a plow and a plow-beam, of a suitable axle, means carried thereby for securing the said plowbeam transversely thereof, and means for adjusting the wheel-carrying ends of said axle to various horizontal planes.

It further consists, in combination with the plow and its beam, of an axle extending transversely to said beam, means for securing said beam and axle together, Wheels carried by the free ends of said axle, means for securing a maximum length of bearing between said wheels on the axle,and means for adjusting said wheels from a minimum to a maximum gage upon the axle.

It also consists in certain other novel constructions, combinations, and arrangement of parts, as will be hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 represents a perspective view of my improved attaching means, the plow carried thereby being shown by dotted lines. Fig. 2 represents an enlarged detail view, in top plan, of the axle and its attachments. Fig. 3 represents a fragmentary longitudinal horizontal section through the'squared bearing of the axle and one of the locking-sectors. Fig. 4 represents an enlarged detail View of one of the corner-castings of the axle. Fig. 5 represents a similar view of the caster and its clamping attachment; and Fig. 6 represents a vertical transverse section through the -squared bearing and axle, illustrating in side elevation the clamping means for the sleeve of the locking-sector.

In the art to which the present invention relates it has been found desirable to provide means whereby a plow of the ordinary walking type may readily be transformed and employed with facility as a riding-plow, and in the production of such attachments an adjustment of the traction-wheels to various horizontal planes has been found necessary in order to accommodate the said Wheels to the contour of the ground being operated upon and also tocontrol the depth of furrow. In. order to attain these and other Valuable results, I employ, as willbe seen by the said drawings, in connection with any suitable plow, as 1, preferably of the double-burster type, having any desirable and well-known form of beam 2, a transversely-arranged supporting-axle, as 3, which axle is composed of bars 4 and 5, having their inner ends held in contact with each other and retained in position by means of a squaredtubular bcar ing, as G, which incloses said inner ends for a suitable distance. Each of the rods et and 5 is formed exactly similar to the other, and a description of one may be applied equally as well to the other, and I will therefore describe but one anddesire the description to be applied to both. The rod is extended horizontally for a suitable distance and carries upon such horizontal portion an adjustable collar, as 7, provided witha set-screw 8, designed to contact with the outer end'of hub 9, revolubly mounted upon said horizontal portion forretaining the same against lateral outward movement, and a sleeve, as 10, provided with a set-screw 11, engages the inner end of said hub and prevents inwardlateral movement thereof, the said sleev, .being formed with suitable dust-proof anges, as 12, designed to inclose said inner end of the hub. It will be apparent that the set-screws 8 and 11 may be caused to lock the sleeves 7 and at any desired points longitudinalof the horizontal portion of said bar for controlling the gage of the traction-wheels carried by the axle 3. At a suitable point intermediate the length of the bar 4 the same is bent from a horizontal to a vertical plane, as indicated at 13, the said bend being sufficiently great to cause that portion of the bar beyond the point of the bend to extend in a diagonal plane outwardly, and the bar is next formed with a comparatively large bend to bring the inner portion thereof again to a horizontal plane. It will be seen that by these gooseneck bends within the bars 4 and 5 the horizontal portion between the larger bends thereof is given the greatest possible length, while the distance between the smaller curves 13 is reduced to a minimum and the lower horizontal hub-carrying portion of the bars thereby permitted to have a maximum length. About the curve 13 is clamped a two-part casting, as 14, each of the parts of said casting being made exactly similar to the other,

each being provided With a semicircular notch, as 15, and a second semicircular notch 16. Surrounding notch 16 and extending laterally therefrom is a dust or sand guard flange, as 17, the said flange being spaced from the notch 15 by an abutting shoulder 18 a distance equal to the thickness of the inner end of hub 9, whereby when said castings have been clamped together by means of bolts, as 1919, about the bend 13, the semicircular notch 15 surrounding the diagonal portion of the bar and the notches 16 the horizontal portion thereof, the said hub 9 may be moved inwardly, the collar 10 having previously been removed from the axle until its in nerend abuts againstthe shoulder 18 and is guarded by flange 17. Each of the castings 14 is formed with a laterally-extending lug or car, as 20, apertured, as at 21, for purposes hereinafter disclosed. It will be apparent that each of the castings 14, as above suggested, is formed exactly similar in every respect to the other, whereby an interchange of the castings from one of the bends 13 to the other may be made without the confusion arising from a right and left casting with respect to the relative position of the bends. Of course it will be seen that the statement with reference to the similarity of these castings does not apply with reference to their relative positions when applied to a particular bend, as the castings of course must be made in pairs. The notches 15 and the notches 16 of each pair of castings are arranged to register with each other, respectively, the castings being otherwise similar in all respects, and a right casting upon one bend 13 may with facility be employed as a left casting upon the other bend, and vice versa.

The inner ends of bars 4 and 5 are preferably held in contact with each other within the squared tube 6, which tube is prepared by forming the same square and then passing a drill longitudinally therethrough, thereby cutting away portions of its inner wall, as at 22 22, whereby the rods 4 and 5 may be readily passed within the tube 6 and snugly fit therein. Surrounding either end of the tube 6 is a preferably squared sleeve, as 23, slotted longitudinally through its under wall, as at 24, and provided with depending lugs 25 upon either side of said slot, a bolt, as 26, being passed throughsaid lugs for clamping the same together and closing the spaces between slot 24, whereby the sleeve 23 is caused to tightly clamp tube 6 and be retained in position. By reference to Fig. 3 it will be seen that the outer end of the sleeve 23 is formed with a circumferential inwardly-extending shoulder, as 23, which fits snugly about its respective bar 4 or 5, the bar carrying a lug 51, which is introduced through the slot 24 before the clamping operation and which engages the shoulder 23 on one side and the respective end of tube 6 on the other, so as to retain its bar against longitudinal movement and at the same time permit rotation thereof. The outer end of the 'sleeve 23 is formed, preferably, with an integral sector, as 27, provided on its periphery with suitable ratchetteeth, as 28. Outside of the sectors 27 are arranged operating-levers, as 29, each provided with an eye 30, surrounding its respective bar 4 or 5, and any suitable cotter-pin, as 30, is preferably-passed through the said bar for preventing lateral movement of said eye. Each lever 29 is provided with a suitable pawl, as 31, designed to engage the teeth 28 of sector 27 for locking its respective lever against movement. Any suitable gripping means, as arms 32 32, carried by levers 29, may be connected by rods or otherwise, as is well known, to the pawls 31 for releasing the engagement thereof for permitting movement of the levers. Each lever 29 carries an arm, as 33, clamped by means of a bolt, as 34, or otherwise secured to the same, the lower end of which lever is pivotally connected with lug 20 by means of a bolt passed therethrough and through aperture 21, whereby movement of lever 29 will operate to raise or lower the lower horizontal portion of the respective bar and to rotate the upper horizontal portion thereof, the tube 6 and its sleeves 23 and sectors 27 being held against rotation by the weight of the plow-beam 2, which beam is clamped between suitable castings 35 35 by means of suitable bolts or in any preferred manner. Each of the castings 35 35 is rigidly clamped to the tube 6 by means of a bolt 36, having its ends passed through apertures in late rally-extending flanges of the said castings and about said tube, the ends of said bolt 36 being engaged by nuts which may be threaded thereon and contact with said lateral flanges for tightly and rigidly clamping the castings 36 in position upon the tube 6.

In order to provide a suitable seat for the driver, a casting 37 is designed to be held in position upon beam 2 by means of a clampingbolt 38, the said casting carrying any suitable securing means, as bolt 39, for receiving and retaining aspring, as 40, of any suitable form of seat. I also find it desirable to provide the follower-caster common to most ridingplows, and inthe production of such I employ any suitable wheel, as 41, revolubly carried between parallel arms 42, the inner ends of which arms are secured to clamped blocks 43 43, which blocks are clamped about a vertical shaft 44 by means of any suitable bolts 45 45, which bolts also retain the arms 42. One of the arms 42 preferably carries a follower-finger, as 46, designed to free the periphery of Wheel 41 from any foreign substance which may cling thereto. The tubular casting at 47 surrounds the shaft 44 and permits free rotation thereof and is provided with a laterallyextendingclamping-jaw48. Asecondclamp ing-jaw, as 49, is preferably loosely carried by the jaw 48, and in operation the said jaws are designed to be clasped upon either side of the rear and lower portion of beam 2 and held in position by any suitable bolts, as 50 50.

In operation any suitable plow may be transformed into a riding-plow with any desired gage of its traction-wheels by simply securing its beam between the clamping-castings 35 and then adjusting the traction-wheels to the desired gage, as above suggested, upon the axle 3, it being obvious that the contour of the earths surface operated upon may demand that one of the traction wheels move in a higher horizontal plane than the other, and from the above description it will be seen that the shifting of the levers 29 will produce any desired relative position of the said tractionwheels by a sufficient raising or lowering of the lower horizontal portions of respective bars 4 and 5.

Among the many advantages of the invention in the present improved structure attention might be called to the fact that the bearings secured by the squared shaft 6 may, if desired, be longer than the distance between the bends 13 13 through the peculiar gooseneck curves in the bars 4 and 5, whereby a greater leverage is secured for the raising or lowering of the traction-wheels.
