MACHINE FOR MAKING GARDEN-RAKES.

SPECIFICATION forming part of Letters Patent Elm 226,898, dated April 27, 1880.

Application filed July 19, 1879.

To all whom it may concern:

Be it known that I, GEORGE BANISTER, of Columbus, ill the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Machines for Making Garden-Rakes; and I do hereby declare the following to be a true and exact description thereof, adapted to enable others skilled in the art to which it pertains to make and use it, reference being bad to the accompanying drawings, forming part of this specification.

My invention relates to mechanism for cutting teeth in garden-rakes and forming implements analogous thereto.

. The improvement consists in the construction hereinafter described and claimed.

Referring to the drawings, Figure 1 is a view, in side elevation, of such parts of a machine as are necessary to represent the invention. Fig. 2 is a detail view of the elastic blank-holder. Fig. 3 is a plan of the lower stock. Fig. 4 is a reverse plan of the upper stock. Fig. 5 is a section through line S T of Fig. 4. Fig. 6 is an exhibit of a blank after it has been operated upon.

The lower stock, A, is provided with a suitable die, B, secured thereto by a wedge, O. It is further provided with an elastic blankholder, E, which latter consists of two distinct parts, a and I), connected together by a springmetal plate, 0. A transverse slot, (1, is formed in this holder, through which passes'asuitable fastening device, U. By this meansthe holder may be adjusted to and fro in a line which is at right angles to the length of the blank as the latter is in position on the die. This adjustment of the holder regulates and determines the width of the rake-head or other blank.

A longitudinally-tapering gage, D, is connected by tongue-and-groove engagement with the blank-holder, and has sliding movement in the line of its length. The upper stock, J, works up and down in a vertical guideway, (not here represented,) and is provided with a spring, Q. The latter consists of a springmetal bar formed with a return bend, one end of the bar being secured tothe stock and the opposite end being free. This upper stock is further providedwith a punch, P, of the desired form, the'stem of which fits in a slot, 0. This slot communicates with an L-slot formed in the upper stock, and in which fit the two independent wedges N and O. Wedge O bears against the side of the punch-stem, and wedge N bears against the endof the stem. The upper stock is also provided with dies L M, while the lower stock is provided with counterpart dies H I. The blank is subjected to these dies, by which the set is made and the nipple R is drawn out. The shank which receives the handle is afterward welded to this nipple.

To form the teeth the blank is placed on die B in position to be clamped by holder E. On the downstroke of the upper stock the free end of spring Q, bears down upon the elastic holder, and the latter is thereby caused to securely clamp the blank. After the punch has operated upon the blank the upper stock moves on its upstroke, the spring Q is freed from contact with the elastic holder, and the blank is released from its clamp. Said blank is then fed forward, the slide-gage D moving with it and imparting the proper inclination to the line of its teeth. As the punch becomes worn away by grinding it is vertically adjusted in position by wedge N, and is secured in such position by wedge 0.

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

l. The combination, with the elastic blankholder, of the device adapted to compress the latter on the downstroke of the punch, substantially as set forth.

2. The combination, with the punch and die, of the elastic blank-holder and the spring which compresses the latter on the downstroke of-thepunch, substantially as set forth.

3. Thecombination, with the punch and die, of the gage, made in longitudinal tapering form for use, substantially as set forth.

GEORGE BANISTER.
