CULTIVATOR..

SPECIFICATION formingpart of`Letters Patent No. 275,846, dated April 17, 1883.

i Application tiled October 9, 1882. (No model.)

To all whom it may concern Be it known that I, FRANKLIN K.Oav1s, residing at Dixon, in the county of Lee and State of Illinois, and a citizen of the lUnited States, haveinvented new and uset'ul Improvements in Cultivators, of which the following is a full description, reference being had to the accompanying drawings, in which- Figure l is a side elevation with one wheel removed Fig. 2, a rear elevation of the frame, and Fig. 3 a top or plan view ot1 the frame.

The object of this invention is to improve the construction and operation of two-wheeled tongueless straddle row cultivators ot the class commonly known as parallel cultivators; and its nature consists in the attachment of side frames pivotally to the central arch, at the upper and lower extremitiesof the arch, and in the several combinations of parts hereinafter set forth and claimed as new.

In the drawings,Aindicates ordinary wheels; B, ordinary iron plow-beams provided with the usual shovel-plows and handles; C, the rocking plate or bar, to which the beams are attached; D, the pivoted side frames; E, the connecting central arch; F, hang-up hook; G, hangup loop; a., drawbars; b, spindleplates; c, wheel-spindles; d, bolts; e, eyes or joints for the side frames, D; f, rear projections attached to the frames D; g, rod or bar conncting the armsf; h, attachments for the bar l The wheels A and the plow-frames B, with their attachments and parts, may be made of any of the ordinary forms or shapes used for straddle-row cultivators, the form shown being the usual one for iron beams. These beams are attached to the plate or bar C by a pivot or pivotal bolt, whereby the vertical movements for the shovels are obtained, and the lateral movements for the shovels are obtained by the rocking et the plate C in its supporting couplings or attachments h. The upper couplings, It, are extended rearwardly and downwardly, so as to form the hang-np hooks F,and these couplings h are made of forks, with a bolt behind, or in halves, so that by loosening their fastening-bolts, they may be moved along the horizontal portions of the frames D and reset, so as to adjust the space between the plow-beams B or the inner shovels ot the beams, as may be desired.

The frame or arch is formed by attaching two swinging or pivoted side frames to the central areh,E. The arch proper, E,is best made ot' round iron bent into theform shown in Fig. 2, and its lower ends are provided with pins or screw-nuts to prevent the side frames, D,

from working ott. The swinging frames D are made alike, and would be interchangeable eX- cept for the bringing ofthe arm f on the wrong side ot' the central arch, and they are made preferably of flat bar-iron, as shown; butthey may be made ot' round iron fiattened in the necessary places. They are provided with eyes or holes e, through which the central arch, E, passes, and they are nearly ot' the same height as the central arch, as shown in Fig. 2, the top resting against the turn ot' the arch and supporting it, and thepbottom holding the lower ends ofthe central arch, which arrangementpermitsofafree swingingmovementofthe Frames D, and strongly supports the side frames and the central arch in position, and byspreading the joints e from the top to the bottom ot' the arch I avoid the strain which comes upon the lower end ot' the arch when it is made in the form of a bow and supported only at or near the lower end. By my arrangement this connection ceases to be a bow, the connections being made at the top and bottom, as shown.

The parts or spindle-connections b are best made of malleable cast-iron, and the drawbars a may be made of the same material, or of wrought-iron forged substantially into the form shown. These parts are made so as not only to form the wheel and draft-connections, but also a clip to attach them to the frame D by means ot' the bolts d, the-setting of the bolts clamping the parts a b against the outer bar or part of the frame D. It will be evident that these spindle connections may be adjusted up and down upon the swinging frame; but ordinarily the proper adjustment will be made at the shop and will not require changing, as the rocking plates C are provided with holes for raising or lowering the front ends of the plow-beams.

The frames D are provided with rear projections,f, which have holes at their rear ends, into which turned or curved ends of the rod or bar g are placed. This arrangement of the rod g and arms fwith the arch E and swinging frames D permits of a free movement of the hinges or connections e and keeps the wheels moving in lines parallel to each other, although one may be drawn somewhat in advance 0f the other, as in this class ot' cultivators each horse practically draws its own side ofthe machine.

The length of the draw-bars a prevents the arch-frame from tipping forward or back, and prevents it from tipping backward when the plow-beams are hook'ed up and the machine is under motion, and when not under motion the hang-up hook of the plow-beams will tip the frame backward. This may be remedied; but as it results in no inconvenience or difficulty I do not deem it an imperfection.

The form shown for connecting the swinging side frames and the central arch is the one which I deem best; but it is evident that by making the arch E wider it may be made to enter the swinging frames nearer the wheels, and so as to bring the rocking plates C inside of the vertical parts of the arch. )Vith this construction it has the advantage of being somewhat more easily guided by the horses.

By making the draft-bars a of a considerable length, as shown, the machine runs steadier, and is less liable to get doubled up or have the plow-beams come in contact with each other in getting around the ends of the plantrows.

Heretofore a cultvator has been composed of two arches arranged parallel to each other, with wheel-carriages hinged to the lower ends of the arches, whereby the wheel -carriages have independent forward and backward movements. Such, however, does not constitute my invention and is not claimed by me.

What claim as new, and desire to secure by Letters Patent, is-

l. The combination of the arch E and the side frames, D, pivoted or hinged to the vertical portions of the arch, and having at their upper ends the projecting arms f, with the transverse rod or bar g connecting the ends of the said arms, substantially as vand for the purpose described.

2. The combination of the arch E, the side frames, D, carrying attached spindle-plates b, and pivoted or hinged at their extremities to the vertical portions of the arch, and having at their upper portions the projecting arms j j', with the transverse rod or bar g connecting said arms, and the plates or bars C, having swiveled connections at their ends with the side frames, whereby such plates or bars can rock independent of the frames, substantially as described.

3. The combination of the arch E, the side frames, D, pivoted or hinged at their extremities to the vertical portions of the arch, and provided with projecting arms ff, with the transverse rod g connecting the said arms, the couplings h, secured to the upper and lower portions ot' the side frames and capable ot' adjustment thereon, and'the plates or bars G, having their ends swiveled to the couplings, substantially as described.

4. The combination of the swinging side frames, D, ot' a height nearly equal to the central elevation, with the arch E, supported by said frames, whereby the straining ot' the arch is avoided, substantially as specified.
