. To all whom it may concern.-

Be it known that I, FRANK X. KRABACH, a citizen ofthe United States, residing at Deiiance,in the county of Defiance and Stateof Ohio, have invented certain new and useful Improvements in Harrow-Frames; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in harrows, cultivators, and crushers, and among other things it has for its object to provide a frame of a substantial construction, and one in which the forward portion will adapt itself to the unevenness of the ground, while the main or rear portion will remain stiff or uniform in its movements.

A further object of the invent-ion isto construct the frame in sections and so connect the sections that they can be quickly and conveniently folded for storage or transporta' tion, and when being moved from place to place, the inner beams of the outer or lateral sections will serve as runners for the entire device.

A further object of the invention is to provide a flexible and universal connection between the draft 'pole and respective sections of the frame so that each section will be allowed an unlimited and independent movement, and a further object of the invention is to provide means whereby the forward ends of the respective sections of the frame, are close together and may be allowed vertical play and bodily lengthwise movement, while the rear portions of said frame, will be so constiffness or rigidity as it were, so that while s the forward portion of the frame is adapted to give to the unevenness of the ground, the

rear portions are wide apart and will move to-..

gether when met with vertical resistance.

Other objects and advantages will appear from the following description and claims when taken in connection with the annexed drawings, in which* Figure l, is a perspective View of my improved device, showing the'frame provided with harrow teeth and the tongue or draft beam partly broken'away. Fig. 2, is a plan view of the center or intermediate section of frame removed. Fig. 3, is a View of a rear Aelevation showing the same in a folded position, such as when stored away or in moving from place to place, and Fig. 4, is a side elevationvof t-he parts folded, and the draft beam or tongue partly broken away.

Referring by letter to said drawings:-A, indicates the draft beam or tongue, there being but the rear portion illustrated. This draft beam ,has secured to its rear end an angular cross piece a, preferably composed of iiat bar metal, although it may be formed of any suitable material. piece which has its branches directed down- .wardly and outwardly from its point of conmeans of a vertical-bolt e, which has its lower end terminating below said beam in an eye j, for a purpose which will be presently explained. Diagonal braces B, are provided for fixing the lower ends of theangular cross piece a, to the beam, as shown. l

The harrow frame is composed of two similar outer or lateral sections O, and D, and a central or intermediate section E. The lateral wings or sections are composed of two or more longitudinal beams g, and h, which are parallel, or approximately so, and are secured together, at or near opposite ends by means of cross bars or plates F, and G. These cross plates are preferably composed of metal, `and provided at opposite ends with flanges,where by they are secured by'means of bolts i, and nuts or other suitable fastening devices to said beams. The forward cross bars or plates F, are provided on their rear central sides with eyes la, which may be either formed in the plates or secured thereto by nuts or the like, and the lower ends of the angular cross head or bar d, are connected to said eyes by the employment of an eye bolt l-l, which is secured in the eyes on the lower ends of said angular branches by means of a nut l, or the like. It will thus be seen that the forward ends of the lateral wings or sections of the harrow frame, are connected with the draft beam and its angular cross head a, by uni- This angular cross is obvious that more might be employed. These beams have rigidly secured to their forward ends a central longitudinal beam I, which is provided at its forward end with a hook n, designed to receive the eye f, depend,- ing from the rear under side of the draft beam so that said central or intermediate section will'alsov have auniversal and yet detachable connection withfsaid beam, and the for-ward end of the beam I, is also provided with an eye p, for a purpose which will be presently explained.

The oblique or diagonal beams m, of the central section E, are firmly braced in position by means of a cross plate or bar q, and this plate is provided at a suitable distance apart with two upright. fixed posts or studs r, which for the sake of cheapness may be cast integral with the plate. The beam-s m, are furthermore provided on their outer sides and slightly-in advance of the cross plate, wit-h vertically disposed plates K, which are each provided with two eyes s, and ,at varying altitudes; there being one set of eyes disposed opposite each other above the beams to receive a removable bolt or rod L, and another set of eyes disposed in a similar yman- 11er beneath the beams to receive the same` rod or bolt when the harrow has been folded for transportation or storage, as will be presently explained; a cotter pin or key u, being employed for securing the bolt in position.

The plates or cross bars G, at the rearends of the lateral wings or sections are also provided with vertically disposed fixed studs or posts M. The rear portions of the respective frame sections, are designed to be connected to each other in such a manner that each section may have a lengthwise movement independentof the other, but be prevented from lifting or moving vertically without effecting a similar movement in the other sections. The connections are preferably made by means of a pair of bars or straps N, and each of these bars or straps comprises. a straight plate or bar P, and an angular plate or bar Q, connected together with a block R, in-terposed between them, and the said plates or bars are respectively provided at opposite ends with transversely arrangedl coinciding apertures or eyes S.

In using the harrow the eyes at the inner ends of the connections N, are placed over thestuds or posts r, of the intermediate section and the opposite or outer ends of the conf nections are placed so that their eyes will receive the posts or studs M, rising from the lateral wings or sections, after which cotter pins or keys w, are placed in holes at the upper ends of the respective posts or studs, when a hinge connection is effected between the respective sections of the frame and at their rear ends. It will be observed however that the frame sections are prevented from vertical movement at their rear ends independent of each other; the play lor movement being lengthwise only.

The inner sides of the inner longitudinal beams h, of the lateral wings or sections, are provided at or near their forward and rear ends with curvilinear blocks or shoes A', and these shoes are preferably faced with metal straps B', the whole being designed to form runners when the frame has been folded into the position shown` in Figs. 8, and 4:, of the drawings, su-ch as when being transported or soredV away.

C, indicates the seat bean-1. This beam carries the seat D', Xed to the upper side at i-ts rear end and its forward end has fixed toit a hook E', which is designed to engage. the eye p, on the beam I, of the intermediate fra-me section.

F', indicates two similar legs which are preferably composed of stout spring wire. These legs for the purpose of obtaining aspring for the seat are provided at a suitable point in their length witha coil or loop G", and one end of each leg, terminates iin an upward angular branch H', and the opposite ends ter- A minate in a downward angular branch I. The sides of the seat beam have fixed to them, platesor castings K', bearing vertically disposedeyes,land the forward vertical branches of the legs are let into these eyes i-n a pivotal manner. After placing the hook E', in the eye p, of the intermediate section, the outer ends of the legs are placed in vertical holes L', of the connections N, so that they maybe A readily removed and the seat taken o when desired.

The frame being in a position for use, as shown in Fig. l', of the drawings and it being ldesirable to transport the barrow,- or place it Qaway, itis sim-ply necessary to detach the connections N, from the posts or studs of the center or intermediate section and after removingthe outer-ends of the seat legsfrom the holes in said connections, the center section :sho-nld be raised and the lateral sections turn-ed inwardly so as-tohave the-irshoes or runners bear upon the ground. The bolt L, is then removed from, the position shown in 'f Fig. 2, of the drawings, and placed in theeyes lof the plates K', beneath the beams m, and through the. eyes at the inner ends of the confnections N', which connections have been `f swung vertically into the position shown in t Fig. 3, of the drawings, and the bolt or rod thus secured in position. The rear branches of the seat legsfa're then placed on the inner {sides of the beams m, above the plate q, and Ilon the outer sides of thestuds or posts fr. The 1 device may then be driven from place to place yWithout operating in any manner'whatever upon the ground, audit will also be found that IOO IIO

the parts thus connected will be held very secure and compact for packing or transporting. I have not given any detail description of the hai-row teeth which I have shown in connection with my frame, as such teeth form the subject of a separate application for patent, although it is obvious that teeth of any suitable form or character might be employed, or in using the device as a crusher, disks or rollers, or teeth inconnection with disks, may be used, and it is also obvious that the frame may be made small or large and used as a cultivator with either one or two draft animals. lVhile I have described specifically and in detail the parts of the exact construction, and combination shown, yet I do not wish to be understood as confining myself to such precise construction or manner of connecting theparts, but I attach importance to the fact that the sections are so connected that while their forward ends may be allowed a universal movement, independent of each other, the rear ends are so connected that the lifting movement of one will similarly effect the other. The manner of folding the parts is another essential feature as it permits of holding them compact while occupying comparatively little space in shipment.k The sections of the frame being close together at their forward ends and wide apart at their rear ends, it willY be seen that it has no side draft when its sides cut through or pass over obstructions, which is an important advantage.

Having described my invention, what I claim-isl. In a harrow frame, the combination with a central section; of two lateral wings or sections, having a universal connection with the draft beam or frame and close together at their forward ends, and a detachable hinged connection and wide apart at their rear ends, whereby said lateral sections may be turned on their inner sides and the rear connections made to secure the same in such position, sub- 5 stantially as specified.

2. The combination with a central section,

having the verticalstuds or posts thereon; ofv Y.

the two lateral sections provided with shoes or runners on their inner longitudinal beams, and also having vertical studs or posts at their rear portions and connected by aloose or universal joint at their forward portions, and the detachable connection to take over the respective posts or studs and secure the sections together in a horizontal position, and also secure the lateral sections in avert-ical position so as to kbear upon their shoes or runners, substantially as specified.

3. The combination with the central or intermediate section; of the lateralsections, the connections for the rear portions of said sections, each having a vertical aperture, the seat having its forward end connected to the central harrow section, and the legs supporting said seat, and bearing in the apertures of the connections,substantially as specified.

' 4. The combination with'the central or intermediate section,having the hook at its forward end, and the cross bar or plate at its rear portion provided with verticalV studs or posts; of the two lateral sections adapted to be turned upon their sides and provided on their inner longitudinal beams with shoes or runners, and also having cross bars or plates at their rear ends carrying vertical studs or posts, and the respective sections connected to the draft beam at their forward portions, the connections for the rear portions having eyes at opposite ends to receive the respective studs or posts, and the plates on the intermediate section having eyes to receive a. bolt designed to also take through the apertures in one end of the rear connection when the frame has been folded, substantially as specified.

In testimony whereof I aiiix my signature in presence of two witnesses.

FRANK X. KRABACH.
