SAMUEL BOYD, OF` BROOKLYN, NEW' YORK.

MANUFACTURE 0F `IEIOES.

Specicaton of Letters Patent No. 26,560, dated December 2'?, 1859,.

To all whom it 'may concern: y 3

Be it known that I, SAMUEL Born, of Brooklyn, in the county of Kings and `State of New York, have invented a new and useful Improvement in Means Employed for Manufacturing VrOught-Metal Hoes; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l is a side sectional view of my invention. Fig. 2 is a front view of ditto.

Similar letters of reference indicate `corresponding parts in the two gures.

This invention relates to an improvement on a device for manufacturing hoes, for which Letters Patent were granted to me, bearing date August 2d, 1859. In `this `patented device a socket, anvil and mandrel were used and so arranged as to insure a perfect uniformity of manufacture, and an improved article with lessmanual labor than had been hitherto required.

The object of the within-described invention and improvement is to still further reduce the manual labor attending the manufacture of hoes, and at the same time insure a better finish and more desirable article than could be produced by the patented device above alluded to.

To enable those skilled in the art to fully understand, and construct my invention I will proceed to describe it.

A represents a block or support on which an anvil, B, is placed. This anvil, B, is a rectangular block of metal `placed in an inclined position, or having an inclined upper surface or face which should be ofsteel. The block or support, A, may be of wood or metal. The anvil, B, has a vertical hole or opening, a, made in it, and this hole or opening also extends down into the block or support, A. The upper part of this opening, a, is of taper form, and also oval, corresponding to the external form of the eye of the hoe. This upper part of the opening, a, may be termed a socket or die as it gives the external form to the eye of the hoe. In the face of the anvil, B, a taper groove or `re cess, b, is made. This groove or recess co1'- responding inversely with the, ridge or prominence which extends from the eye, c, of the hoe (shown in red) toward the center of its blade or plate, d.

C is a mandrel, which is of taper form, and

transversely it is slightlybval, corresponda" ing to the form of thesocket, a. 1 y This manj drel is of metal, and `it `is smaller in,` diameter `i a than the socket, to allow for the thickness of.. the eye, c.` f In the block orsupport,JA,` a lever, LD, `ish plaed- :The ,innemend "OfthiS lever extends."

i Within the lower Pilltof the opening, a; and f i i :i

it serves as a bearingfor themandrehO, when the latter is fully` driven within jthe: 1, hole or socket, a. y y FV p E E represent two vertical guides,which y ,l are attached, one toeach sidefof the blockory. f y support, A, and are connected at theirup- `7o per endsby a traverse bar, e. `Betweenythe 1 i two guides, E E, whiclrare` of ai suitable height a weight, G, lis placed; Said` weight i serving as a drop or die. Thiszweightlis of 51 metal and has an inclinedface or bottom, corresponding with the inclination of `the 13 anvil, B, (see Fig. L), the, face of the weight V or drop being perfectly smooth.` The weight y also has a vertlcal opening, f, inadefthrough l it, the diameter of said opening correspond- 3 ing with that `of the openingaf. y The `open?` 1 ing, f, is in line withthe opening, a, as shown clearly in Fig. l. i f y x The anvil, socket and` `mandrel arepre- 1 if, cisely similar to those shown in the device` i formerlypatented by me. l 1 The device is used as follows: The hoes are Y forged, as usual, with the eyes, @,attached and they are taken in a rough state from the i hands of the forger, properly `heated, and"` placed, one, of course, atfatime, on theanvil, B, the eye, c, being fttedinthe socket,a The weight, G, being previously raised, is then allowed to descend by its own gravity, g and swages the hoe in proper form, reducing the blade or plate, ,to a properthickness, l, wg forming the prominence at the inner side; of` the blade, and givingithelatter a properl oblique position, relatively` with the eye, c." 1 The weight, Gr, performs, the work that `was 10c formerly done manually,and `it will be seen i that by its use the process of manufacture` will be greatly expedited-M lVhenthe weifrht,f G, has performed its work the mandreh,` is f placed in the opening,`f,of the weight, G,"10`5`; and the mandrels driven downby hand or` k otherwise so as to form the eye c, ofthe hoe,` x the mandrel causing the `eye to expand and ,l fill the socket, and forming` or finishing bothl its internal and externalparts.` V11@ The opening, in the weight, Gr, serves as a guide to the "mandrel, lnsurlng` a vertical l position of the same While b'eing driven down thro-ugh the eye, c. weight, G, serves to confine the metal around the edge of the eye, and prevents a bur being formed thereon by the action of the mandrel. The Weight, G, therefore, it will be seen, performs a double function, to wit: that of a weight or drop, and a guide for the mandrel. The lever, D, is merely to throw the mandrel, C, upward out of the weight or drop, when the finished hoe is to be removed.

I do not claim the anvil, socket and mandrel for they have been previously used, and were patented by me as previously alluded to. Neither do I claim broadly the employment or use of a weight or drop for that is At the same time theV a common device and in general use for analogous purposes; but

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

The combination with the drop Gr, and anvil B, of the drop opening f, and mandrel C, so that after the drop has given its blow it will hold the hoe in place and allow the mandrel C, to be passed through it into thehoe to form and inish the eye thereof all as herein shown and described.
