HARROW.

SPECIFICATION forming part of Letters Patent No. 666,667, dated January 29, 1901.

Application led September l1, 1900. Serial No. 29,717. (No model.)

To all whom t may concer-72,:

Be it known that I, JOEL HABEN, a citizen of the United States, residing at Palmyra, in the countyof Fluvanna and State of Virginia, have invented a new and useful Harrow, of which the following is a specication.

This invention relates to harrows in general, and more particularly to that class comprising an angular frame having rigid teeth extending downwardly therefrom and adapted for engagement with the eartht-o effect the harrowing operation.

The object of the invention is to provide a construction in which the frame will consist of a number of parts removably connected, so that the shape of the harrow may be varied for dierent operations, and also in which the parts are hinged together to enable them to adjust themselves to inequalities in the ground, and also to permit raising of the sections to free the teeth from obstructions.

In the drawings forming a portion of this specication, and in which similar numerals of reference designate like and corresponding parts in the several views, Figure 1 is a plan view showing the complete harrow with its weight in place. Fig. 2 is a top plan view showing the harrow in its converted condition. Fig. 3 is a perspective view showing one of the supplemental frames of the harrow. Fig. 4 is a perspective view showing a form o f double tooth which is secured at the rear of the central beam. Fig. 5 is a section on line 5 5 of Fig. 1.

Referring now to the drawings, the harrow comprises a central beam 10, at the sides of which are fixed the remaining portions of the harrow, these side portions being duplicates, so that a description of one side sufces for a description of the other.

At each side of the beam 10 and at the forward end thereof is fixed a plate 11, having a perforated outwardly-projecting ear 12 at its rear end. These ears are engaged by hooks 13, fastened upon the outer faces of the front ends of the side members of the harrow. Each of the side members consists of an outside beam 14, which lies at an angle to the central beam 10 and diverges therefrom rearwardly. To the front end of the beam 14 is fixed a beam 15, which lies parallel to the beam 10 and extends rearwardly somewhat more than half the distance of the beam 14, said beam 15 being connected adjacent to its rear end to the beam 14 by means of a crosspiece 16. Upon the inner face of the beam 15 and adjacent to each end thereof is fixed a plate 17, having an outwardly-projecting ear 18, said ears being perforated to aline with corresponding perforations in the ears 19 of plates 20, fixed to the corresponding face of the beam 10. Through these alining perforations is passed a pintle 21, having a head at one end and a key 22 atthe other to prevent its displacement. Thus the beam 14 and the parts connected therewith have a hinge connection with the central beam 10 and may be raised and lowered with respect thereto.

In the rear of the cross-piece 16 and between the rear end of the beam 14 and the beam 10 is disposed atruncated triangular frame 23, the outer side of which lies parallel with the beam 14 and the rear side of which is in line with the rear ends of the beams 10 and 14. The minorfront end 24 of the frame 28 is removably and pivotally connected to the cross-piece 16 through the medium of hooks 26, which engage the eyes 27 of eyebolts passed through the cross-piece 16. The major rear end 28 of the frame 23 is connected at its outer extremity with the rear end of the beam 14 by means of a metallic strap 29, bolted thereto.

The frame 23 at each side of the beam 10 is provided with any desired number of harrow-teeth, as also are the beams 14 and 15 and the cross-piece 16, the barrow-teeth in the cross-piece being shown at 30'. When it is ,desired to form a rigid harrow, the crosspieces 16 at opposite sides of the beam 10 are mutually connected -by means of a metallic straprO, passed transversely and beneath the beam 10 and connected with said crosspieces, as also with the beams 15. The frames 23 are also connected by means of a brace 31, passed through alining staples 32 upon the upper surfaces of the inside beams of the frame and the beam 10, said brace being further held against displacement by bolts 33 or by barrow-teeth passed through their connected portions.

In addition to the teeth above mentioned two teeth are attached to the rear end of the IOO beam 10 in the form of a staple 34, the legs of which pass downwardly at opposite sides thereof to a sufficient extent to enter the earth, the staple being held in place by a bolt 34', passed through perforations 35 in the legs and an alining perforation formed transversely through the beam 10.

Handles for the barrow are provided and consist of two upwardly and rearwardly diverging bars 35, the meeting ends of which are bolted to the beam l0 and the rear ends of which are provided with grips 36. A V- shaped brace 37 is bolted to the beam 10 and has its extremities connected with the portions 35, which latter are 'further strengthened by means of a cross-brace 38. Chains 39 are each attached at one end to the bars 35 adjacent to the grips 36 and at their opposite ends to the rear ends of the beams 14, supplemental chains 40 being connected with the chains 39 and the rear outer corners of the frames 23 to permit movement of the connected portions of the barrow by means of the handles.

When it is desired to use only the frames 23, the beams 14 and 15 and cross-pieces 16 may be removed by withdrawing the pintles 21, unbolting the plates or straps 29, and disengagng the hooks 13, after which a crossbrace 41 is secured to the under side of the beam 10 and extends laterally therefrom to support the front ends of the frames 23. Supports 42, one at each side of the beam 10, are then passed through staples 43, projecting upwardly from the front and rear portions 24 and 28 of the frames 23, and are continued forwardly and convergingly to meet and have their meeting ends attached to the beam l0 and secured in any desired manner.

It will of course be understood that in practice teeth of any desired kind may be employed and that they may be distributed over the parts of the structure in accordance with any preferred system, and the connectingbolts may be in the form of teeth to perform a double function.

When it is desired to increase the weight of the barrow for more effective operation under certain conditions, such a weight in the form of a log or beam 45 may be placed transversely of the beams 10 and 14 and secured thereon by means of chains or ropes 46, fastened to the ends of the beam or log, and which may be attached to the frame of the barrow in any desired manner.

Having thus described the invention, what is claimed is- 1. Aharrow,comprsingacentralbeain,'har row-frames pivotally connected with the central beam and having their outer portions eX- connected with the first-named frames intermediate `of their iearwardlyextending portions and the central beam.

2. A harrow,comprisinga central beam,har row-frames pivotally and removably connected with the central beam and having their outer portions extended rearwardly, and supplemental frames connected with the firstnamed frames and lying between their rearwardly-extended portions and the central beam.

3. A barrow, comprising a central beam, frames pivoted to the central beam and having rearwardly-extended portions, supplemental frames pivoted to the first-named frames and lying between their rearwardlyextending portions and the central beam, handles connected with the central beam, and iiexible connections between the handles and the supplemental frames.

` 4. A harrow, comprising a central beam having perforated ears, frames having hooks engaging certain of said ears, ears upon the frames having perforations alining with the perforations of the corresponding ears upon the central beam, pintles passed through the alining perforations, whereby the frames may be removably connected with the central beam, supplemental frames removably connected with the iirst-named frames, handles connected with the central beam, and flexible connections between the handles and the frames.

5. A barrow comprising a central beam, frames pivotally and removably connected with the beam, supplemental frames removably connected with the first-named frames, connections between the supplemental frames and the central beam, and brace-receiving means carried by the supplemental frames and disposed to receive and hold braces in position for connection with the central beam.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
