SIDE HARROW.

SPECIFICATION formingpart'of Letters Patent No. 651,282, dated June 5, 1900. Application filed November 29, 1899. Serial No. 738,712. (No modem T0 66 whom it may concern:

Be it known that I, THOMAS RILEY WALLIs, acitizen of the United States,residing atLouisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Side Harrows; and I do hereby 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 itappertains to make and use the same.

My invention relates to side barrows, and particularly to the construction of the frame; and it consists of a frame composed of two pieces which are bent into proper shape to form the general shape for said frame, said pieces overlapping or extending side by side along one side of the frame, so as to form space-connecting bars for the attachment of the teeth and to provide for the vertical and lateral adjustment thereon.

The invention also consists in certain other details of construction, as will be hereinafter described and specifically claimed.

In the accompanying drawings, Figure 1 is a perspective View of a side harrow constructed in accordance with my invention. Fig. 2 is an enlarged detail perspective View of a portion of the frame upon which the teeth are secured. Fig. 3 is a detail perspective view of one of the teeth, showing its manner of attachment to the bars. Fig. fis a top plan view of the same. Fig. 5 is a vertical section through one of the teeth and clamping means, and Fig. 6 represents detail perspective views of the difierent parts for securing the teeth in position and permittin,

of their adjustment.

l in the drawings represents the frame of my improved side barrow, which consists of two metal pieces 2 and 3, the piece 2 being bent into triangular form, with its apex slightly rounded, as at 4, and the piece 3 bein g also bent into triangular form and having one of its sides, as 5, extending parallel with one of the sides 6 of the piece 2 and having one of its ends connected to one of the ends of the piece 2, as at 7, by means of bolts and nuts, as clearly shown, which forms the forward or front end of the frame. The other ends of the pieces constituting the frame are left disconnected exceptwhere they are joined by means of the devices for securing the teeth imposition, as will be hereinafter described. Sufficient space is left between 'the'sides 5 and 6 of the pieces 2 and 3 to permit of the insertion of the teeth 8 and alsofor clamping-blocks 9. One clamping-block is provided for each tooth, and said clamping-block is provided on one of its faces with a groove or recess 10, which receives the side bar 6 of the piece 2, the flanges of the clamp ing block or piece resting 011 the upper and under sides of the said bar. The upper and lower edges of the clamping-block 9 are provided with

recesses

10 and 11, in which the-members of a U-shaped clip 12 are seated. This U-shaped clip incloses the

side pieces

5 and 6 on top and bottom and is provided with screw-threaded ends to receive nuts 13.

A plate or strip 14 is interposed between the nuts and the side bar 6, as is clearly shown. From this construction and arrangement it will be seen that by unscrewing the nuts 13 the U-shaped clip can be loosened and the tooth can be raised or lowered to different positions or can he slid along to any point desired on the

side bars

5 and 6 and then the nuts tightened up, so as to secure the tooth in such position. It is of course obvious that the teeth can be adjusted to any place on the

bars

5 and 6 without being raised or lowered, and vice versa.

With my construction and arrangement I produce a very strong, light, and simple side harrow which is very efiective in its construction and operation and which secures a means of supporting the teeth between parallel bars and also permits of the teeth being adjusted either vertically or laterally independently of each other and of a single tooth to be removed and another tooth put in its place. I consider the construction of the frame composed of only two pieces and so bent as to give the frame the proper shape and at the same time secure spaced bars at one side of the frame for the attachment of the teeth a very important feature of my invention, irrespective of the manner in which the teeth are secured in position on the frame.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A harrow comprising in itsconstructiou a triangular frame, composed of two pieces, which are bent into proper shape to form the said frame, the pieces along one of the sides being spaced apart and the forward ends of the pieces being secured together, and teeth secured between the double or spaced portion of the frame, substantially as described.

2. A barrow comprising in its construction a triangular frame composed of two pieces, which are bent into angular shape to form the said frame, the pieces along one side of thefranie being parallel and spaced apart, and the forward ends of the pieces being secured together, and teeth secured between the double or spaced portion of the frame in such a manner as to permit of their adjustment, substantially as described.

3. A harrow comprising in its construction a triangular frame, composed of two pieces,

which are bent into angular shape to form r the said frame, the pieces along one side of 1 j clip extending across the double portion on top and bottom and along the opposite sides of the tooth, the ends of said clip being threaded and nuts on said threaded ends for securing the parts in place, the construction and arrangement being such that upon loosen ing the clamp, the teeth can be adjusted vertically or slid along the double portion and secured in such adjusted position, substan-' tially as described. 7

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