SPECZPICATION forming part of Letters Patent. No. 337,773, dated March 9, 1886.

Original application filed November 7, 1875). Divided and this application filed March 14, 1884. Serial No. 124,196. (No model.)

To all whom it may concern:

Be it known that I, CHARLES LA Dow, of the city and county of Albany, and State of New York, have invented certain new and useful Improvements in Wheel Harrows or Cultivators, of which the following is a specification.

My invention relates to that class of machines having a gang or gangs of revolving disk cutters or wheels which are arranged to work at anangle to the line of draft, and capable of adjustment relatively thereto.

The accompanying drawings show all my improvements as embodied in one machine in the best way now known to me. The details of construction may, however, be varied in many ways without departing from the spirit of my invention.

Figurel represents a plan or top view of my improved machine with some of the parts removed. Fig. 2 represents a section therethrough on the line 2 2 of Fig. 1; Fig. 3, a transverse sect-ion through the center of the machine with the gang-bars and superposed parts arranged in the same plane. Fig. 4 is an enlarged sectional view of one of the balland-socket joints. Fig. 5 is an enlarged sectional view of a compound thimble forming one of the bearings of the gang-shaft. Fig. 6 is a detail view showing some of the connections between the main frame andgangshaft and parts connected therewith. Fig. 7 is a sectional detail view on the line 7 7 of Fig. 1. Fig. 8 is a view of the seat and supporting-standard. Fig. 9 is a cross-section through the seat-supporting standard. Fig. 10 is a plan view showing the foot-lever and link-connections for reciprocating the scraperbars laterally and simultaneously. Fig. ll is afront elevation of the same.

The main or draft frame of the machine is shown in the drawings as composed of a crossbar, D, a tongue or pole, E, and double or bifurcated braces H,extending from the ends of the cross-bar to the tongue, and preferably secured to both the top and bottom of both the crossbar and tongue, these parts being securely united at their points of junction. Obviously the construction of the frame may be varied. Thedisks A,u-'hichareof concavoconvex form, are loosely mounted upon the shafts N N, and are kept at suitable distances apart thereon by means of spacing-thimbles L and C, also loosely mounted on the shaft. In the present instance four disks and three spaciug-thimbles are shown in each gang. The middle thimble, O, in each gang consists of a spool, 71, the enlarged heads h of which respectively conform to the concave and convex sides of the disks between which it is placed. A loose sleeve, Z, enveloping this spool is provided with a spherical enlargement, Z, aboutits middle. A boxing, M, envelops this spherical enlargement Z, and is flared out or cut away, as shown at 0:, so as to allow a vertical and horizontal play of the thimble within it. This box or hearing is made in two sections, and secured over the thiinble by means of bolts and nuts in a wellknown way. An oil-duct, 0, through which the bearings are oiled, extends through this boxing and the spherical enlargement on the sleeve. A pin or teat, Z, on the spherical enlargement Z works in a recess, m, in the boxing, and prevents the spherical enlargement from revolving within the boxing. This construction gives a flexible or rocking draftconnection between the disk-gangs and the main frame,which connection admits offreely varying the relative angle of the gangs, and also allows the vertical rocking of their inner and outer ends in passing over inequalities in the surface of the ground. I do not confine myself to the use of such a draftconneotion, nor to the specific construction or arrangement herein shown, as these parts may be constructed and arranged in any other way. Draft-bars J, hinged or pivoted on the under side of the cross-bar D at each end, so as to allow horizontal play of their outer ends, project rearwardly over the boxingsM. Other bars, J",which may also be employed, are similarly pivoted on the upper side of this cross-bar at each end, and also project rearwardly over the boxings, and are bent down,as shown, so as to rest upon the bars J. These bars are shown as secured to their respective boxings by means of the bolts and nuts,which unite their sections. The upper bars, J are to act as braces to resist or limit the vertical movement of the gang-shafts N at their bearings and relieve the bars J from strain. They may be removed,'however,and, should it be desired, the bars J may be secured to the frame in other well-known ways, and so as to prevent a vertical movement of their outer ends. 'Both bars are shown as connected with the top of the boxing; but they might be otherwise connected, if desired. By thus pivoting the draft-bars J and bars J and also by connecting them with the disk-gang by a rocking or hinge connection, the lateral movement of the gangs caused by their vibration or by changing their angle, as will hereinafter be described, is fully compensated. The other thimbles, L, consist each; of a spool, h, similar to thatheretofore described. Fitting loosely over this spool is a sleeve, Z upon one side of which is an enlargement or' lug, 1*. Upon opposite sides of these lugs are pivoted parallel supporting-bars o,whieh are pivoted to and support the beams G. The normal inclination of these bars is outward from the machine, and their movementin that direction islimited by a spur or stop, F, on the lug Z. I prefer this manner of'connecting the beam G with the gang; but any other well-known way could be adopted, if desired. Bars H H, pivoted to both ends of the crossbars D, are also pivoted to the beam G,-the bars H being preferably bent up and pivoted to the upper sides of the beamsfwhile the others, H arepreferably pi voted to their under sides. It will be observed that these-bars form a flexible draft-connection between the crossbar and beam and permit the ends ofthe gangs to vibrate vertically and horizontally independently ofthe frame without interfering with the lateral motion of the scrapers. I prefer such a construction as that shown; but obviously other Well-known forms of flexible connections could be employed for connecting the beam and cross-bar.

carried by the disk-gangs fo'rm draft-connections, as do the connections between the gangshafls and the frame, before described, and if the latter connections were omitted the former alone would constitute sufficient draft-connections between the gangs and frame. I

I prefer to mount the scrapers on the beam, as shown; but they may be carried on the gang or beam in any other well-known way. They may be automatic'in operation or may be operated by the attendantin any known manner without departing from the principlesot' my invention.

Pendent scrapers are secured upon the beams G by means of slots and set-screws, (or other welt-known equivalent adjusting devices, so that they may assume different positions relatively to the disks.

It will be observed that the scrapersmay bemoved together as a gang, and also that each scraperhas the capacity of being independently related to its disk, so as to act upon it in the'most cfficient manner. The organization shown is a practical and efficieut one; butobviously other ways of adapting the scrapers Of course these flexible con-- nections between the frame and the beams tively to the frame.

I am the first to employ a stop incombi'na 'nection.

to inequalities in the distances between the disks may be employed.

Boxes F for the reception of weights to hold the disks down to their work may be mounted on the gangs, if desired.

Thejostling of the inachine will cause the pendent scrapers to enter the concave faces of the disk and clear them of clogging matter. I provide, however, handles Q Q within reach of the driver, by means of which-he can draw the scrapers up to the wheels to clear them, when desired.

The disk-gang shafts N N are preferably united by a flexible universal joint connection, which is constructed in the manner described in my prior patent.

The disks A, spools h, shafts N, and sleeves I on the shafts in each gang are securely locked together by means of the usual clampnuts, n n, upon the ends of the shaft, and by the construction of the thimbles and ball-and collars upon the shafts, against which th ner disks in each gangcould abut, instead of.

abutting against the sleeves'I, as shown in-the,

drawings.

A cutter or tooth, 0, may be secured "upon the boxing of the ball-and -socketjoint to euta furrow between the two gangs of'disks. The

angle of the'disk-gangs relatively to the line of draft is varied and controlled by a flat draw-bar, a, which is shown as'inflexibly bolted to the boxing B, and pivoted at its forward end to a lever, d, pivoted on the main frame of.the machine within reach of the driver, audheld in any desired position by a This plate braces the bar- In disk-barrows having vibratory gangs the gangs sometimes unduly rise at their inner ends. In order to prevent this action, I' employ a stopint-erposed'between the frame and the gang. The drawings show the stop as formed solely by the bar a, which is limited in its Verticalmovement by the cross-bar D-.

Other forms of stop than that shown may-be used between a gang and cross bar to limit the upward movement of the end of the gang relation with a gang carrying a beam upon which scrapers may be mounted, which beam is connected with the frame by aflexible draftrc'onterposed directly between the gang and frame.

I am also the first to use a stop in:

Such stop or means for preventing the rising of the inner ends of the gangs may therefore be varied without departing from my invention. The draft-bars J are free to swing at their rear ends in ahorizontal plane when the ends of the gangs vibrate vertically, or when horizontally adjusted, and the adjustment and vibration of the gangs is permitted by this flexible connection between the frame and gangs.

I have described the beams on which the scrapers are shown as mounted as capable of being controlled by the driver from his seat by means of handles; but as it is desirable that the driver should have his hands free to manage the team, I also provide means for controlling the scrapers by the drivers feet. (See Figs. 10 and 11.) The bars H' are extended a short distance beyond their pivots on the cross-bar D, and are connected by means of link-rods K with a double crank-arm, K, secured upon a shaft, K mounted in bearings K on the frame, and controlled by a foot-lever, K, within reach of the driver, rocking on the same pivot as the crank arm. It will thus be seen that by depressing one side or the other of this foot-lever both gangs of scrapers may be made to simultaneously approach the disks or to recede from them, as may be preferred.

This or other mechanism may be operated by the hand instead of the feet, if desired.

The drivers seat S, which is supported by a standard, R, mounted upon the inner end of the draft-frame of the machine, extends backward over the ends of the gang-shafts.

The operation of the machine will readily be understood from the foregoing description.

This application is a division of the application filed by me November 7, 1879, and patented April 22, 1884, No. 297,524, and the machine herein illustrated and described is the same as the machine shown in said patent, and any subjectmatter claimed in that patent is hereby disclaimed in this case.

I claim as my invention- 1. In a disk-harrow, the combination of a pole, a cross-bar, a disk-gang, a beam connected to and Vibrating with the disk-gang, a scraper carried by said beam, (said scraper having lateral motion relatively to the side of a disk,) a flexible connection which attaches said beam directly to the cross-bar, so that the beam and its disk-gang may vibrate up and down at their ends independently of the crossbar, and mechanism for varying the angle of the gang.

2. The combination of a disk-gang, an end wise-moving scraper-bar which reciprocates across the vertical planes of the disks, aseries of scrapers, one for each disk carried by said bar, and devices for securing the scrapers to their bar, so as to permit their independent adjustment relatively to the disks.

3. In a disk-barrow, a main frame, a diskgang, a ball, a pin thereon, and a case or boxing for the ball, in combination with a draftarm for connecting the disk-gang to the main frame at a point to one side of the line of the draft-pole.

4. In a disleharrow, the arrangement, substantially as set forth, of the pole, the crossbar, and the bifurcated braces secured to both the cross-bar and pole, and the disk-gangs attached to the crossbar and vibrating in rear thereof.

5. In a disk-barrow, the combination of a main frame, two gangs of disks, two gangs of scrapers, and mechanism for operating both gangs of scrapers simultaneously.

6. The combination of a pole and frame, disk-gangs connected therewith, mechanism for adjusting the angle of the gangs, scrapers which act or move together as a gang, and connections between the scrapers and their support, whereby each scraper is independently adapted to work in proper relation to the face of its disk.

7. The combination of the following three elements: first, a frame; second, a disk-gang capable of vibrating vertically and horizontally independently of the frame, and, third, a stop interposed directly between the gang and frame to prevent the gang from rising at its inner end.

8. The combination of a cross-bar, a diskgang vibrating independently of the crossbar, a beam mounted on and vibrating with its gang, a flexible draft-connection uniting the beam directly to the cross-bar at a point outside of the vertical line of the pole, and a stop which prevents the gang from rising at its inner end, but permits the horizontal movement of the gang relatively to the line of draft.

9. In a disk-barrow, the combination of a pole, cross bar, disk-gang, a draftarm hinged at its forward end to the cross-bar at a point outside the vertical line of the pole and hinged at its rear end to the disk-gang, and mechanism for adjusting the angle of the gang relatively to the line of draft.

10. In a disk-barrow, a cross-bar, disk-gangs vibrating independently of the crossbar, means for flexibly connecting the gangs to the cross-bar, scrapers carried by the gangs and having lateral motion relatively to the sides of the disks, in combination with means for adjusting the angle of the gangs.

11. The combination of a pole, cross-bar, disk-gang, a beam carried by the gang, a balland-socket joint for connecting the gang and its beam to the cross-bar, and an arm hinged to the frame.

12. The combination of a draft-frame, a gang of disks, laterally-moving scrapers for acting agai nst the disksand mechanism whereby the driver can operate the scrapers with his foot.

In testimony whereof I have hereunto subscribed my name.
