No. 434,110. Patented Allg. 12, 1890.
UNITED STATES PATENT OFFICE.
FRANK J. HENRY AND FREDERICK A. TAYLOR, OF KALAMAZOO, MICHIGAN.
SPRING-TOOTH-HARROW FRAME.
SPECIFICATION forming part of Letters Patent No. 434,110, dated August 12, 1890.
Serial No. 335,888. (No model.)
.To all whom t may concern:
Be it known that we, FRANK J. HENRY and FREDERICK A. TAYLOR, citizens of the United States, residing at Kalamazoo, county of Kalamazoo, State of Michigan, have invented a new and useful Spring-'lootli-IIarrow Frame, of which the following` is a specification.
This invention consists in the below described and claimed construction, designed to eect greater simplicity and strength of the barrow-frame.
In the drawings forming a part of this specification, Figure l is a broken plan View. Fig. 2 is an elevation of Fig. l. Fig. 3 is a sectional elevation on line 2 2 in Fig. 1, and Fig. 4 is an enlarged inverted detail in perspective.
Referring to the lettered parts of the drawings, the tooth-bar B is made hollow and rectangular in cross-section. The cross-bar A, which when in use in a harrow-frame in which a number of tooth-bars are employed attaches the tooth-bars B together in proper position relative to each other, may be channel-iron or angle-iron provided with mortises fu, fitting over the upper side of the rectangular bars B; or the cross-bar A may be solid without chanuels or angles, if preferred.
At D is shown a casting provided with a mortise m, fitting the under side of the toothbar B, Fig. 3, said casting forming a seat for the shank of the barrow-tooth C. On the under side of the shank of the tooth C is a binding-clip e. Bolts S pass up through the binding-clip, the seat, one at each side of the rectangular hollow bar B, and up through the cross-bar A, and thus binding all these parts together.
By employing bars B rectangular in crosssection and hollow and square mortises inthe bar A and seat D and having the bolts S at the flat sides of the bar B we are enabled to produce a very light frame, and one in which the clamping parts are less liable to displacement, and one in which the tooth-bars are stronger in comparison to their weight than any we have heretofore known.
To guard against displacement of the seat D lengthwise of the tooth-bar B, we form a hole through the lower wall of said tooth-bar B, and provide the seat D, in the mortise 'n thereof, with a lug a, which lits into the hole of said bar, as in Fig. 3.
Having thus described our invention, what we claim as new, and desire to secure by Let- ,ters Patent of the United States, is-
rectangular in cross-section, the cross-bar having the square mortise fitting over said toothbar, the tooth-seat having the square mortise fitting one face of the square tooth-bar, a tooth, and the binding clip and bolts, substantially as set forth.
In testimony of the foregoing we have hereunto subscribed our names in the presence of two witnesses.
FRANK J. HENRY. FREDERICK A. TAYLOR.
