UNITED STATES PATENT OEEICE.
JAMES ALFRED SHITTON AND ROBERT MITCHELL, OF N'TOLVERHAMPTON, COUNTY OF STAFFORD, ENGLAND.
IMPROVEMENT IN MACHINERY FOR FORGING PIPE-lOINTS AND OTHER SIMILAR ARTICLES.
Speeilieation forming part of Letters Patent No. 5S,963, dated October 1G, 1866.
.To all 'whom it muy concern Y Be it known that we, JAMES ALFRED Surr- ToN and ROBERT MITCHELL, both of Wolven hampton, in the county ot' Stall'ord, England, engineers, have invented Improvements in Shaping' and Forging` Metals and in the lllachinery and Apparatus Employed Therein and we hereby declare that the following is a full, clear, and exact description of the same, ref erence being had to the accompanying drawings, and tothe letters of reference marked thereon.
Our said invention relates to a new method ot'manut'acturing gas-' ttings known as Ts/l elbowsf bends,7 crosses, and couplings, and other gas-fittings by machinery worked by steam, water, compressed air, or hand power, such machinery bein g applicable to shaping and forging other metallic articles.
Under the moditication in which steam is employed one part ot' the machinery consists ot' a sole or base-plate having two horizontal cylinders bolted thereon, with pistons having' dies ofthe required shape fitted in thc end ot' each, and which meet or converge on steam being applied at the back of each piston. At this point there is a block7 or mold7 secured to the sole or base-plate, and over which a vertical cylinder is carried on a suitable frame-work havingl a piston titted with a mandrel or die, the pistons ot' all these cylinders being actuated by steam regulated by valves.
According to another form of machine which may be used for forging, planishing, and tinishing such articles, cylinders are placed at requisite angles having pistons iitted with mandrels or dies for the purposes ot' shaping, torging, and finishing the aforesaid articles, these cylinders being bolted to a training attached to the sole or base-plate, which has a block or mold secured to the same at the point where the dies of the pistons meet, and having movable mandrels worked by levers and slides operatcd upon by a vertical cylinder and piston.
In applying the aforesaid machinery to the manufacture of gas-fittings, as above named, or other metallic articles, we take a piece ot iron stamped or otherwise prepared to the required shape, and lay it on the block or mold of the tirstsdescribed machine and place a mandrel upon the same, and canse the piston ot' the vertical cylinder, containing another mandrel, to descend on such tlrst-nau1ed mandrel, which compresses the iron into the block or mold and causes the edges to turn up, and, by admitting steam at the back of the pistons ot" the horizontal cylinders, we cause the dies in the pistons of such cylinders to come together and further compress the iron into the required shape upon the said mandrels, and, by repeated blows from these. pistons containing the dies, (which can be obtained by the admission and emission of steam in the cylinder,) shape such articles tothe required form. And in order that our said invention may be t'ully understood, we shall now proceed more particularly to describe the same, and for that purpose we shall ret'er to the several figures on the accompanying drawings, which form a part ot this speciiication, and in which the same letters of reference indicate correspondin g parts in all the corresponding figures.
Figure 1 ou the accom panying sheet ot drawings is a front elevation, partly in section, of one modilication ot' our machinery for shaping and forging metals. Fig. 2 is a plan ot' the lower part of the same, and Fig. 3 is a transverse vertical section ot' the machine. Fig. 4 is a front elevation ot' the second or tinishing machine. Fig. 5 is a side elevation of same, and Figs. Gand T illustrate the various relative positions ot' the mandrels and diesavhen operating upon the piece ot' metal to be shaped.
A A are two horizontal cylinders, Figs. l, 2, 8, which contain the pistons B and are bolted onto the sole or base-plate C. Each ot' these pistons carries a die, l), of the required form. A block or mold, E, shaped or indented according to the desired shape of the article to be produced, is secured to the sole or base-plate where the dies converge or meet at a central position between the two horizontal cylinders.
A vertical cylinder, F, carried on the framing II H and containing the piston Gr, is placed over the block or mold E, this piston carrying a mandrel, I, or other suitable tool. a is the metal plate, represented as already shaped in the form ot a T-piece. 1t is laid flat, in the tirst place, upon the block or mold E, and upon it is placed the mandrel I. The mandrel I is then brought down upon the center of the mandrel I' und forces the plete into the mold, causing its edges to turn up, in which comlition it is acted upon by the horizontal dies l) D, which approach und turn over the edges of the metal onto or around thc mundrels I and I'. Steam is admitted to both the horizontal cylinders A A by menus of the valve J, contained in the chamber l, which is supplied by the pipe L, and after doing` its duty it escapes through the pipe M. Steam is also admitted to the vertical cylinder l? by means of the valve N, contained in the vulve-chamber 0, which is supplied by the pipe l?, und et'tcr doing its duty escapes through the pipe Qt. These valves are Worked by levers or other suitable appliances.
We cluim as our invention and desire to sccure by Letters Patent- The construction und urrungcment of niuchinery or apparatus for shaping und forging metullic articles, substantially :ts hcreinbctorc described, und illustrated by Figs. l, 2, und 3 of our drawings.
In testimony whereof' We have signed our names to this specification in the presence of two subscribing Witnesses.
