Description
UNITED STATES PATENTr OFFICE.
ALFRED B. SEYh-IOUR, OF OLAVERAOK, NEV YORK.
Specification forming part of Letters Patent No. 12,971, dated May 29, ISST).
To @ZZ '107mm t may concern: Beit known that I, ALFRED B. SEYMOUR,
Y of Claverack, Columbia county, New York,
have invented a new and useful improvement in the manufacture of stove-pipes by means of an improved machine herein described; and I hereby declare that the following is a full and exact description.
To enable others to make and use my invention, I proceed to describe its construction and operation, reference being had to the drawings hereunto annexed, and making part of this specication.
Figure l is a front elevation of the machine. Fig. 2 is a front elevation. Fig. 3 is a birdseye View. Fig. et shows the gage-plate en larged; Fig. 5, the saine-an edge view. A
The construction of my spiral sWaging-Inachine consists in combining with the sWageA a gage-plate, B, and different sizes of screws D, (with gages,) to cause the swages to move nearer `to the gage-p1ate in forming the screw.
The article to be made is generally stovepipe With'screW-joints.
This machine can beset for as many sizes of pipe as there are screws D, with their corresponding gages, E.
Upon the top edge of the gage-plate (see Fig. 5) there is a finger or indicator, F, upon which a scale is 'marked By turning 'the thu1nb-screw Gthe gage is set at any angle required, the scale marked and numbered upon the indicator being the guide for the operator. lVhen the gage-plate is set, it is required to set the gage E in the proper screw D, the screws D being linade fine or coarse, according to the size of pipe to be made. When both are setto correspond, the pipe is swaged in the ordinary manner of swaging; but the effect produced is different, a spiral being formed by the sWaging-rollcrs being moved up toward the gage-plate. The frame of the machine should be of iron, and of any forrn.
The parts of the machine-not niinutely described are like corresponding parts in ordinary sWaging-niachines. 4
lVhat I claim as niyinvention, and desire to secure by Letters Patent, is*
The plate B (having a gage) between the shafts of the creasing-rollers, and adjusted by a set-screrv,-so that the proper inclination may be given to the end of the pipe.
ALFRED B. SEYMOUR.
lVitnesses:
OWEN G. VARREN, I. S. SEYMOUR.
