UNITED STATES PATENT OFFICE.
AMOS NV. SANGSTER, OIF BUFFALO, NEV YORK.
IMPROVEMENT IN DIES FOR TUENING FLANGES.
Specification forming part of Leiters Patent No. 37.876, dated March l0, 1863.
To @ZZ whom it may concern:
Be it known that I, AMos W. SANGs'rEE, of the city of Buffalo, in the county of Erie and State of New York, have invented a new and useful Machine for Forming the Flanges on Lantern or other Rims; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and the letters of reference marked thereon.
The nature of my invention consists in an upper and lower die, such asis represented in Figure 2 of the accompanying drawings, for the purpose of forming a doubled Iiange on lantern-rims, with a rounded or smooth edge on the inner side of the flange and rim, thus avoiding a cutting-edge, which would cut or otherwise injure the hands while cleaning the inside ofthe lantern to which said rims may be attached, and at the same time forming said rim nearer to a circle than it could be donc by hand.
To enable others skilled in the art to make and use my invention7 I will proceed to describe its construction and operation.
Fig. 2 in the accompanying drawings representsavertical section of the machine. Fig. l represents a lantern-rim before it has been subjected to the operation of the machine; and Fig. 3 represents a rim after it has been iinished in said machine.
The same letters in Figs. 1, 2, and 3 repre sent similar parts in each.
In Fig. 2, B represents the upper die, which is connected to the press or drop with ascrew at the shank A. This die moves vertically up and down while the machine is being operated.
G is the base or bottom die, which is fast to the press by screws and is stationary.
E E represent the ilange (in Fig. l) partially formed or swaged, and ready for the l finishing operation, as shown in Fig. 2. This swaging is done by the common swagingmachine, such as` are generally used by tinsmiths.
Fig. 8 represents the rim with the fiange pressed down and finished.
The machine is operated as follows: The upper die, B, is raised upward far enough to admit ofthe rim D, as represented in Fig. l,
which it (the rim) then surrounds. The die B is then' brought down (until its rim C slips over the rim on the die G) and doubles or rpresses the iiange down, as shown at E E, and at the saine time the bottom surface of the rim or projection C on the die B presses against the projection F F on the lantern-rim and presses it slightly outward, which gives eX- actly the same distance between the tlange E E and the projection F F in every rim made.
What I claim as my invention, and desire to secure by Letters Patent, is-
The dies B and G, constructed and operated as and for the purpose set forth.
AMOS XV. SANGSTER.
Vitnesses:
N. D. MENOAR, JAMES MENOAR.
