T0 all tui/1,0m t 'may concern:

Beit known that we, GEORGE W. Goss and CHARLES. E. Goss, citizens of the United States, residing at Baltimore, in the county of Fairfield and State of Ohio, have invented a new and useful Cultivator, of which the following is a speciiication.

This invention relates to riding-cultivators; and among the objects of the invention are to simplify and generally to improve the construction and operation of this class of devices.

Vith these and other ends in view, which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that the right is reserved to any changes, alterations, and modiiications to which recourse may be had within the scope of theinvention and without departing from the spirit or sacrificing the efliciency of the same.

In said drawings, Figure 1 is a perspective front view of a cultivator constructed in accordance with the principles of the invention. Fig. 2 is a detail view, enlarged, in sectional elevation. Fig. 3 is a detail rear elevation. Fig. 4 is a detail plan view. Fig. 5 is a detail View of the axle-adjusting means. Fig. 6 is a detail view of the gang-supporting means. Fig. 7 is a perspective detail view ofthe footlever frame and the handle-crank connected therewith. Fig. 8 is a sectional detail view of one ofthe gang supporting wheels or rollers.

Corresponding parts in the several figures are indicated throughout'by similar characters of reference.

The frame of the improved cultivator includes a rear member 1, which preferably consists of a bar of channel-iron or steel of suitable dimensions. The side members of the frame have been shown as being composed each of an upper and a lower bar 2 2, the rear ends of which are connected with the ends of the rear member 1, as by means of vertical bolts 3. The front of the frame is j tion.

likewise composed of an upper bar 4 and a lower bar 4, here shown as angle-bars, land the ends of which are connected with the front ends of the side bars 2 2 by means of vertical bolt members 5, spacing tubes or sleeves 6 being mounted upon the said bolts for the purpose of properly spacing the upper and lower frame members. The side members 2 and 2 are connected intermediate their ends by bolt members 7 and spacingsleeves 8. The bolts 7 also serve to connect the sides of the frame with cross-bars 9 and 10, the former of which is supported upon the upper end members 2 2 and is constructed of round, preferably tubular, iron, while the cross-bar 10, which has been shown as a flat strap, is supported upon the lower end members 2 beneath the spacing-sleeves 8. A very simple and durable, approximately rectangular, frame is thus constructed, which is specially adapted to contain the gangs and operating mechanism which is to be hereinafter described.

Upon the front side of the rear or main.

frame member 1 near the ends of said frame member are provided bearings 11 and 11, in which are journaled a pair of stub-axles 12, one at each end, Said axles having cranks 13, terminatin in spindles 14, upon which the carrying-w eels 15 are supported for rota- Upon the inner bearings 11 are mounted clip members or plates 16, having depending lugs 17, each adapted to engage one of a plurality of segmental recesses 1 8 in the stubaxles, thus providing for the lateral adjustment of the latter, so that the gage of the machine may be regulated according to the distance that the rows of plants which are to be operated upon are apart from each other. It is obvious that such adjustment may be very easily effected by temporarily loosening or detaching the plates 16, which lare retained in operative position by screws 18 or other suitable means.

The lower end members 2 of the frame support rack segments 19 concentrically, upon which are pivoted hand-levers 20, having stops 21, whereby they may be retained in adjusted position,

Said levers are connected, by means of link-rods 22, with collars t IOO adjusted so as to adjust the ends of the carbetween the latter by means -Near the ends of the Jframe are obliquely-disswingletrees 32.

rying-frame vertically and independently of each other. In the drawin s the lower ends of the levers 20 have been sown as being bifurcated, so as to embrace the rack-segments. This construction is preferred; but it is not essential.

The implement herein shown is adapted to to be drawn by three horses walking abreast, and it is therefore provided with two tongues 24, the rear ends of which extend between the front frame members 4 and 4/ and between the cross-bars 9 and 10, being secured of bolts 25.

posed braces 26, the forward ends of which are secured upon the bolts 5 at the front corners of the frame, while the rear ends of said braces are secured uponthe bolts 25. The braces 26 are reinforced by auxiliary braces 27, the rear ends of which are secured upon the bolts 7, whereby the upper and lower side bars 'of the frame are intermediately connected. The front ends lof the braces 27 are connected with the braces 26 by means of bolts 28, which also form fulcrums for the equalizers 29. At the upper front corners of the frame are hooks 30, upon which are suspended draft-bars A31, carrying the outer Said draft-bars are connected, by means of linksl 33, with vthe outer ends of the equalizers. The inner ends of vthe equalizers are connected, by means of links 34, with the arms 35 of a bifurcated member 36, carrying at its lowerend a middle swingletree 37.

The seat-supporting bar of the device has been shown as'comprising two members 38 and 39, here shown as'constructed of Thalfvround iron, the upper member being supported u on the rear channel-bar 1 and extending geneath the cross-bar 9 and the front frameebar 4, while the lower member 39 exy tends beneath the rear channel-bar 1 and the front iframe-bar 4', the cross-bar 10 having a central or intermediate dip ed portion which extends beneath the mem er 39 to assist insupporting 'thelatten Thearms of the bifurcated sWingletree-supp'o'rting member 36 are pivoted'upon a bolt or pin 40, extending through the upper seat-bar member 38 near the front vend ofthe latter. Said upper seat-l bar member is bent downwardly in rear of the channel-bar 1 and is connected with the lower'member'39, 'with which it contacts by means including a clip 41, supporting the seat 42.` j 9 Upon the upper front frame member 4 are suitablyfsiipported,clips 43, with which are ivotallyy connected rearwardly extending bars V44,."halving downturned rear ends 45 which l"ei'tend through collars or bearings upon ralat'erally-slidable bar 46, which is supportedinrear of the channel-bar 1 as by means ofkeysor pins 47, passing through the 4members 45. The collars or bearings,"

which are designated 48, are firmly supported upon or connected with the slide -bar 46. Upon the bars 44 are journaled wheels 49, which travel upon the upper side of the channel-bar 1. The slide-bar 46 is provided with depending bracket members 50, in which are journaled rollers 51, bearing upon the under side of the channel-bar, which latter thus not only serves as a guide or track for the respective wheels and rollers, but also to prevent upward or downward displacement of the slide-bar 46.

The front frame members 4 and 4 are s aced apart at various places intermediate t e ends thereof by meansof spacing-'sleeves 52, through which extend connecting-bolts 53. The sleeves 52 afford bearings for clipplates 54, which consist simply of bent plates U-shaped in cross-section and having their free ends connected by bolts 55, upon which are mounted the front ends of the beams 56 of the individual cultivator-gangs 57, which latter are of ordinary construction, being provided with standards 58 and earth-engaging blades 59 of the ordinary or any well-known or approved construction.

The laterally-slidable bar 46 is provided with bearings 60 for the outer ends of rockshafts 61, the inner ends of which have bearings in rack-segments 62 and 63, which are likewise secured up on and extended upwardly from the sliding bar 46. The rock-shafts 61 are provided at their outer ends with cranks 63', which are connected, by means of linkrods 64, with the outer members of the cultivator-gangs, said members being rovided with plates 65, through which said ink-rods extend, the latter being provided beneath said lates with means, such as nuts 66, to enab e them to be utilized for lifting the members of the gangs. The rock-shafts have hand-levers- 67 fixed thereupon, as by means of set-screws 68, and provided with stops 69, adapted Ato engage the rack-segments 62. Pivoted loosely u on the rock-shafts near the inner ends of the atter are levers 70, having stop members 71,' engaging the rack-segments 63. Saidl levers are provided with arms 72, connected by link-rods 73 with the inner members of the `cultivator-gangs, which are provided with plates 74 of the link-rods, which are provided with means, such as nuts 66a, to prevent their withdrawal. The' link-rods 64 and 73 are provided with stops 74 between which and the gang members are disposed coiled springs 75, exercising pressure in a downward direction and tending to hold the gangs in operative engagement with the ground when the device is in operation. It will be seen that by means of the levers 67 and 70 and related parts the outer and inner members G and Gr of the cultivator-gangs are capable of being independentlyv adjusted vertically.

T e laterally-slidable bar 46 is provided IIO for the passage with downwardly-extending arms and 76, the outer ones of which, 7 5, are slidably connected with the outer members G of thecultivator-gangs, while the inner arms 76 are in like manner slidably connected with the inner members of the cultivator-gangs G. The arms 75 and 76 are connected adjustably with the slide-bar 46 by means of clips, as 77, which will admit of said arms being suitably spaced apart, so as to regulate the distance between the cultivator-gangs andthe individual members thereof, thus enabling the machine to be very readily adapted to operate upon corn or other plants planted various distances apart. A pivotal bolt 78, which extends vertically through the seatbar members 38 and 39, constitutes afulcrum, upon which vis pivotally mounted a lever-frame 79, having two depending members spaced apart by means of a brace 81, through which the pivotal bolt 78 extends, each of the members 80 being provided at its lower end with a foot-piece or treadle 82. The upper end of the lever-frame 79 has a rearward-extending arm 83, securely connected therewith and provided with a handle 84. The arm 83 is connected, by means of a link-rod 85, with an eye 86, formed upon one of the sleeves or vcollars 48, connected with the slide-bar 46. It will be seen that by manipulating the hand and foot levers, which may be done simultaneously by the operator, who is seated in a convenient position in rear of the foot-lever, the slide-bar 46, with all its related parts, will be moved laterally in either direction, thus providing for the lateral adjustment not only of the members of the cultivator-gangs, but also of the means whereby said gangs are manipulated or adjusted to their various positions.

rlhe wheels 49, which travel upon the upper side of the channel-bar of the frame, are preferably of the construction illustrated in detail in Fig. 8 of the drawings, by reference to which it will be seen that said wheels have hubs 87, between which and the bars 44 are interposed antifriction-rollers 88, which are retained by means of washer-plates 89, adj acent to the hubs, said washer-plates being retained in position by means, such as cotterpins 90.

From the foregoing description, taken in connection with the drawings hereto anneXed, the operation and advantages of this invention will be readily understood by those skilled in the art to which it appertains. It has been endeavored to provide a separate and thoroughly-serviceable frame of light and durable construction and well adapted to support the cultivator-gangs and the adjusting and operating mechanism for said gangs. The ends of the gang-carrying frame are capable of independent vertical adjustment, which is desirable under many circumstances. Means are also provided whereby not only the gangs but the individual members of said gangs may be adjusted transversely, so as to provide for any variation in the distance between the rows. It will further be observed that the inner and outer members of the gangs are capable of independent vertical adjustment, which is obviously desirable. which have been designated, respectively, as the inner and the outer members, may obviously be interchanged when desired, according to the character of the work to be performed.
