IMPROVEMENT IN CULTIVATOR-TEETH.
.50 all whom it may concern.-
Be it known that we, CHARLES H. SAYRE and GEORGE KLlNoK, of Utica, in the county of Oneida and State of New York, have invented a new and useful Improvement in Cultivator-Teeth and we do hereby declare that the following is a full, clear, and exact description of the same, reference being bad to the accompanying drawings thereof, which make part of this specification, and in which Figure 1 represents a view in perspective of one of my improved teeth having a reversible point applied thereto, the tooth being attached to the frame, which is represented as broken off; Fig. 2, a vertical longitudinal section of the same, taken centrally through Fig. L Fig. 3 represents the blank tooth as cut out of a sheet of metal preparatory to being swaged' into shape; and Fig. 4 represents a view in perspective of our improved tooth as attached to the frame without having a reversible point applied thereto.
The nature of our invention consists in making a tooth with a hollow or tubular shank from thin or sheet metal, on'which is cut a screw-thread, through which it is secured to the frame by means of a nut or their equivalents. To strengthen and support the shank there are two braces in rear and araised'bead in front, they being severally formed on that end, brought in contact with the under side of the rail or frame, so as to form a shoulder or hearing on every side, which, being firmly drawn up to the frame by means of the nut and screw, prevent it from working loose and yield the necessary strength to resist pressure.
The plate A and shank B are first cut out of a sheet of metal in one piece of the proper shape, and then swaged into the necessary form for atooth, the shank being bent round to the frame by means of the nut F.
On the upper end and at the rear of the plate A are two shoulders, G, formed .by cutting ott' the upper portion of the plate from the lower preparatory to forming the tubular shank, and
which, together with the bead H, form a shoulder in front and rear of the shank.
To prevent the shoulder G from cutting the under side of the frame, a piece or plate ofmetal may be let into the frame to form a bearing for them. On the upper side of the frame, between it and the nut F, is placed a washer, a", for a like purpose.
On the plate A, Fig. 1, is represented a reversible point or tooth, K, which may be made of any required shape or size. This point is secured to the plate by means of a screw-bolt,
its head being made slightly convex on thesurt'a'ce, and tapering on its under side to fit into a countersunk mortise through the point K and plate A.
Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-- 7 So constructing acultivatortooth that when made of thin or sheet metal a part thereof shall form a tubular shank, B, whereby said tooth may be drawn up and securely attached to the frame, substantially as described.
In testimony whereot'we have hereunto subscribed our names.
