A IMPROVEMENT-|N MACHINES FOR MAKING SHOT. i

Specification forming part of Letters Patent No. 122,102, dated December 26, 1871 antedated December 6, 187.1..

I, WILLIAM W. BRIGG, of Home, Greene county, Tennessee, have invented certain Improvements in Machines for Manufacturing Shot, of which the following is a specification:

My improvement consists insupplyin g a new article of manufacture, made of indestructible material, whereby novices as well as those skilled in the art can make shot at their homes and firesides with a certainty and precision not heretofore attained, and will thus inaugurate a domestic system of manufacturing capable of extension into every family of the United States, economical to those who use shot and profitable to those who may manufacture it for sale.

Iam aware that portable shot-machines have ybeen previously made but after two or three years of experiment and effort to introduce them, they are to be found nowhere in market. They have not apparently answered the purpose inf tended, on account of their perishable and unreliable character as well as their mechanical defects. Being made of wood, they are warped and twisted out of a true plane by the contact of the hot lead and thus their successful operation is defeated.

It is a well-known fact that a certain and uniform temperature must be maintained in the manufacture of shot, and when the molten lead comes in contact with a substance (the machine) at a much lower temperature it is chilled and the operation of shot-making stopped. Now, by my machine, being` made of iron or other metal, this difficulty is avoided, as it can be heated to the desired temperature before operations are .'commenced, and so prevent that chilling and cooling process referred to; thus providing the farmer, the mechanic, the gunner, and amateur sportsman with a machine, at a nominal cost, which, by its use, secures to each of them a saving of from one to tive hundred per cent. or more in the cost of their ammunition.

The prevailing opinion of those who havn heretofore experimented with wooden shot-machines has been that metallic ones would not operate successfully, which experience has disproved.

Theoperation is as follows: Take a common paper card of suitable size, perforate it with small holes, leaving the burs prominent; press the lugs B B through it; then place the lugs into the openings a a, Fig. 1; then insert the pins c c in said lugs to prevent lateral or vertical motion of card and hopper F, except that given to the whole apparatus; sprinkle upon the burred side of card powdered sal ammoniac or borax;

have ready a pail full of cold water; place the machine so prepared upon the pail, with the lugs G, Figs..I and II, on outer diameter; then have your `molten lead ready, pouring a little on the card between the holes so as to fusethe sprinkled powder.; then let the assistant continue to pour the lead therein while the operator has hold of the knob E, and rubbing, from the commence' ment to the end of the work, with a heavy stick or billet of wood upon the notches in thecorrugated handle, which will impart a trembling motion to the whole machine and to the lead, causing it to disintegrate into drops, which, imping,

two parts, with a nonconducting handle or knob-v y i Figure I being a plane view without the hopper F; and Fig. [I being an edge or side view, showing the hopper F in position, with lugs G B B land toothed, corrugated handle and pins c c; Fig. III being a plane view of the hopper, and

Figs. IV and V being edge or side viewsof hopper, showing lugs, pins, and pin-holes; Fig. VI being the perforated card, marked w.

y In Fig. I, a a representopenings of any size or form in base of machine, into which the rectangular or any other form of lugs B B, Figs. II,

IV, and V, are inserted, and secured thereto and therein by pins c c, as seen in Figs. IV and'II of hopper, &c., (the perforated card being secured between the hopper and base of machine,) which prevents any lateral or vertical motion of the hopper independent of the whole machine. DD, Figs. I and II, represent the corrugated form of of handle to give additional strength thereto, in

.consequence of the deep notches cut or cast therein. E representsthe knob. G, in dotted lines, Fig. I, and in section, Fig. II, represents 122,102v p s the 111g to hold the machine in position on pail. The hopper F, Fig. III, is made with angular As a new article ofmanufaeture, the shot-inasides and ends. A chine herein described, consisting of the handle Experience hasV demonstrated that when it is D E G, hopper F suitably securedV thereto, and

I claim as my inventiondesirable to make large quantities of shot at one the perforated card x, the whole constructed and time it is better to have two ladles, in order that arranged substantially as described.

the temperatureof the lead may be kept uniform, Y VILLIAM W. BRIGG. as the ladle becoming emptied cools od rapidly, as also does the lead remaining on the card when the assistant ceases pouring hot lead thereon.
