HAR ROW.

SPECIFICATION forming part of Letters Patent No. 326,704, dated September 22, 1885.

Application filed February 7, 1885. (N0 model.)

To all whom it may concern.-

Be it known that I, JAMES H. BARLEY, a citizen of the United States of America, re siding at Sedalia, in the county of Pettis, and State of Missouri, having invented certain new and useful Improvements in Harrows, of which the following is a specification.

My invention relates to certain improvements in harrows; and it consists, first, in producing a barrow-tooth rail made from a plain, ordinary bar of iron or steel, by pro viding means, formed integral therewith,for supporting the teeth thereto by rolling, punching, stamping, pressing, bending, or otherwise forming coherent stops thereon or within the body of said rail, by which means the teeth are supported at any desired angle; second, in combination with a harrowtooth and rail, apivotal bolt which passes through perforations made through both the tooth and rail, the outer or head portion of said bolt provided with an elevated orarched portion, each one of the ends of which extends out in opposite directions or at right-angle with said bolt, with the two ends thereof bent or turned down or inwardly a sufficient distance to rest on the side of said rail on opposite sides of the tooth, forming an elevated or T-shaped arch over the side of said tooth. Said pivotbolt is provided with a key or a thread and tightening-nut on its point end, by which the bolt is screwed up tight against the side of the rail, clamping the tooth in place thereto, and yet allowing it to freely move'or turn upon its pivot.

The object of my invention is to provide means for attaching and supporting the harrow-teet-h directly to a plain metal rail with out the intervention of holding-blocks of any kind.

Another object of this invention is to provide a plain metal harrow-tooth rail with suitable shoulders or stops formed thereon or within the body of said rail for supporting the teeth, whereby the necessity of providing flanged or other speeialshaped iron for the construction of said harrow-rails is dispensed with, thereby greatly reducing the cost of their production.

A further object is to so construct and adapt the stops formed on or within the body of metal rails for supporting the teeth thereon as to admit said teeth being attached thereto by a pivotal bolt or pin, allowing the teeth to automatically adjust themselves to a vertical position when the harrow is drawn from one end and at an inclined position when drawn from the other end.

Another object is to provide a suitable pivotal clamping-bolt which passes through both tooth and rail, and is so constructed and adapted as to clamp the tooth to the side thereof, and yet allowing them to play freely without any liability of the nuts or fastenings of said pivot-bolt becoming loosened.

All the above-named objects I attain by the mechanism illustrated in the accompanying drawings, making part of this specification, and to the letters and figures of reference marked thereon, as hereinafter more fully described, and pointed out in the claims.

In the drawings, Figure 1 represents a face View of a portion of a metal barrow-tooth mil with the means of attaching and supporting the tooth thereto at different angles; and Figs. 2, 3, 4, and 5 are similar views, showing modifications. Figs. 6, 7, and 8 are views of the rail in vertical cross section, taken through the lines m 00, Figs. 1, 2, and 3. Fig. 9 is a longitudinal edge view of a portion of the rail with the means formed thereon for supporting the tooth; and Figs. 10, 11, 12, and 13 are similar views showing modifications. Figs. 14 and 15 are side views of the pivotal clamping-bolt. Fig. 16 shows a vertical crosssection of a barrow-tooth rail as made lighter and supported by ribs on its back side. Fig. 17 is a vertical cross-section of the plain harrow-rails before the stops are formed thereon.

In the drawings, A represents the harrowtooth rail of which the sections are formed. B are the teeth, and 0 are the solidified shoulders or stops for supporting the teeth thereon, which stops are formed integral with said rail from a plain ordinary bar of metal by rolling, punching,stamping,pressing,bendingor otherwise forming said shoulders or stops thereon or within the body of said rail, as before mentioned.

In drawings Figs. 1, 6, and 9, four separate shoulders or stops, 0, are formed or raised from the edges of the rail A by the use of dies or other means adapted to the purpose, the metal bars from which said rails are preferably made being first heated. Said shoulders or stops are formed toprojectout from the face side of said rail, and are 'so arranged thereon as to support the teeth either in a vertical or an inclined position, as shown in solid and dotted lines. These shoulders or stops 0 may be varied somewhat in the manner in which they may be formed or raised upon the rails A. The metal 0 on the edges of the rail, intervening between the two cavities G 0, formed by raising the stops 0 O therefrom, as shown at Fig. 9, may also be raised with the stops 0 O, and made to project from the side of the rail A, a sufficient distance to admit the tooth being passed loosely between the body of said rail and the outer raised portion or bar 0', as shown in drawings Fig. 12, or, in order to avoid bending these raised portions or bars 0 far enough from one side of the rail to receive the tooth therein, the remaining central portion, 0 ofsaid rail, intervening between the two raised portions or bars 0 O, is also bent out from the opposite side of the rail A, forming a vertical opening, 0 between the two raised bars 0' O and the bentout central portion, G of the rail A, to receive the harrow-teeth,which are supported therein by the shoulders or stops 0, formed at suitable distances apartlongitudinally with saidrail A to give the teeth the desired angle at which they are to stand, as shown in drawings Figs. 2, 4c, 5, 7, 10, 12, and 13; or, if preferred, the metal may all be bent out on one side of the rail obliquely across the face thereof, in a similar manner to the bent-out central portion, 0 drawing Fig. '1, or like what is shown in the extreme outer edge View of said rail at drawing Fig. 9, thus forming the solidshoulders or stops 0 at the requisite distances apart to give the teeth the same pivotal movement,as shown in drawings Figs. 1, 2, and 3. The teeth are secured in the openings 0 by a pivotal bolt or pin, which passes through perforations formed through both the tooth and rail, as before mentioned.

I do not confine myself to forming the shoulders or stops 0 O at equal distances apart upon the rails A, as shown at Figs. 1., 2, and 3, as it will be observed in drawing Fig. 4 the shoulders or stops 0 G on the upper edge of the said rail may be formed just far enough apart to receive the tooth therein and allow a slight movement, while the shoulders or stops 0 O at the lower edge thereof are formed apart a distance proportionate to the angle at whichthe tooth is to be inclined, in which instance the heads of the teeth will be shouldered and suitably perforated to receive a key at the top of the said rail to retain the teeth therein, and yet allow them to automatically change their positions.

Figs. 5 and 13 show the openings 0 formed in the rail A, as above described, the size of the tooth to be used, which are driven vertically through said openings sufficiently tight as'to require no other fastenings to hold them rigidly therein at whatever angle they are intended to stand.

Figs. 3, 8, and 11 show anotherslight variation'in the manner in which the shoulders or stops 0, which support the tooth, may be formed from the body of the rail A. Inv this instance the rail is made somewhat thicker, and a suitable tool or die is prepared and adapted to the purpose. The rail being first heated said tool or die is then made to penetrate the edges thereof, by which operation the metal is raised on one side of said rail A, forming the shoulders or stops 0, which support the teeth, leaving the cavities C in the edges of the rail; or the shoulders or stops 0, asshown,may also be formedintegral therewith by making said rail of malleable iron or caststeel. In order to clamp the teeth against the sides of the rail, as shown at Figs. 1 and 3, in such a manner that the teeth will automatically adjust themselves into the desired position,

and yet remain in proper posit-ion upon the rail without any liability of them becoming loosened, a suitable clamping pivotal bolt is employed.

' At Figs. 14 and 15, D is a pivot'bolt, which is provided with an elevated arched portion, D, which projects out at right angles, on either side of the bolt D, with the two ends D D bent or formed to point'downward in line with the bolt D,said bolt being provided with a key ora thread and tightening-nut on its end,the teeth and rail being provided with perforations,through which the boltD is passed, with the ends of'the two arms D D resting on the sideof the rail A at opposite sides of the said teeth. Said arms'D D are spaced apart, and are made of such a length that when the bolt D is screwed tight to the rail the tooth will be left free to turn on the pivot-bolt D between the rail and the arch D,and are supported in position by the shoulders or stops 0 upon the rail A. This arch portion D may be made separate and provided with a hole through its middle portion, through which the bolt D is passed; or said arch portion D may be united with the bolt D in one piece, as shown at Fig. 15.

At Fig. 10, F is a convenient and cheap pivot-pin, which is provided with a head, the stem being either split apart or formed of two pieces of metal. Said pin is passed through the tooth and rail. The point end is then opened or spread apart, securely retaining the tooth in place, avoiding any liability of them becoming loosened, as is the case with a plain bolt and nut.

Fig. 16 shows how, if desired, the rail Amay be made lighter by forming two ribs, e e, on their back side, between the shoulders or stops, to give them the requisite strength.

. I do not confine myself to either one of the variations in producing or forming the shoulders or stops 0, as shown in detail and above described, as there are still other ways or variations in the manner in which said stops 0 may be formed thereon or within the body of a plain metal harrow-tooth rail, which I deem unnecessary to further illustrate or describe in detail.

My improved harrow-tooth rail A is preferably formed of one continuous bar of wrought iron or steel, having solidified tooth-supporting stops formed thereon at suitable distances apart for attaching the requisite number of teeth to each one of said rails of which the barrow-sections are formed.

Having thus described my invention, what I claimas new and useful, and desire to secure by Letters Patent, is

1. In a harrow, the metal tooth-rail A, constructed substantially in the manner specified, having the integral tooth-supporting stops 0, formed on the side thereof, projecting hori' zontally from the edges of said rail, adapted to support and limit the angle at which the tooth shall stand, substantially as shown and described.

2. The metal harrow-tooth rail A, having the integral tooth-supporting shoulders or stops 0, formed on the side thereofin the manner specified, with the edge portion or portions 0 of said rail projecting horizontally from the side thereof a sufficient distance to admit the tooth passing between said projecting portion or portions 0 and the side C of said rail A, in combination with a harrow-tooth pivotally attached thereto, substantially as shown and described.

3. The metal harrow-tooth rail A, having the integral tooth-supporting shoulders or stops 0 formed thereon, with the two edge portions 0 of said rail projecting horizontally from one side thereof, and the intervening central portion, 0", of rail A projecting from the opposite side thereof, thereby forming an opening between said projecting portions in a vertical direction through said rail, in which opening the barrow-tooth is inserted and supported therein, substantially as shown and described.

at. In a harrow, the combination of the rail A, produced from an ordinary wrought-metal bar of iron or steel having the integral toothsupporting shoulders or stops 0, formed thereon or within a central linewith said rail by rolling, punching, stamping, pressing, or bending, whereby said shoulders or stops 0 are formed at requisite distances apart longitudinally with said rail to allow the teeth to automatically adjust themselves and to stand either in a vertical or an inclined position, and a pivotal bolt or pin adapted to hold said teeth in place, substantially as shown and described.

5. The within-described metal tooth-rail A, constructed substantially in the manner specified, having the integral tooth supporting stops 0, formed on the edges thereof, projecting horizontally from the side of said rail, adapted to support and limit the movement of the angular adjustable tooth, in combination with a pivotal bolt or pin, which passes through perforations formed through both tooth and rail.

' 6. In combination with a barrow-tooth rail provided with means for supporting a swinging tooth thereon at different angles, the "pivotal bolt D, provided with the elevated or arch portion D and D, the tooth and rail, having perforations through them in which the bolt D is passed, with the two arms D D which straddle over the tooth and rest against the side of the rail, allowing the tooth a free pivotal movement thereon, substantially as shown and described.

7. In a harrow, the within-described pivotal bolt D, having the arch portion provided with arms projecting therefrom and straddling over the harrow-tooth and resting on the side of the rail on opposite sides of said tooth, in combination with a perforated tooth and a harrow-rail having perforations and means for supporting an angular adjustable tooth on the side thereof, substantially as specified.

In testimony whereofI aflix my signature in presence of two witnesses.

JAMES H. BARLEY.
