HENRY L. BROIVN, OF INDIANAPOLIS, INDIANA.
AIR-PUMP.
FJPECIFICATION forming part of Letters Patent No. 360,413, dated April 5, 1887.
Application filed July 29, 1886. Serial No. 209.404. (No model.)
To all whom it may concern.-
Be it known that I, HENRY L. BROWN, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, haveinvented certain new and useful Improvements in Air-Pumps, of which the following is a specification.
My invention relates to airpumps such as are commonly used to force air into a vessel, cask, pipe, and the like; and the objects of my improvements are to provide an airpump the valves of which are constructed in a manner so simple that even persons not possessing the same on line 00 m on Fig. 1; and Fig. 3 a
horizontal section through the same on line 2 2 on Fig. 1, drawn to a larger scale.
Similar letters refer to si milar parts throughout the several views.
A is the barrel or cylinderin which the piston B works. The piston B is attached to the piston-rod B, which is secured to and operated by a hand-lever, L, of the usual construction. The plate 0, that forms one end of the cylinder A and contains the receiving and the discharging valves, is constructed in the following manner: At a little distance from the walls of the cylinder A the plate 0 terminates in a cylindrical projection or inverted cup, 0, which extends upward into thecylinder A. In the walls of this cup 0 are a number of openings, .V V. These openings are covered on the inside with an elastic band or v valve.
ing an air-chamber around the discharging valve, is the outlet-pipe E, which connects with the tube or hose II, that conveys the air to the vessel or cask, or thelike,which is to be filled.
The device operates as follows: The upward motion of the piston B draws air from the atmosphere through the openings V V in the walls of the cup 0 into the cylinder A, the elastic band or ring R, that covers the inside of the openings V V in thew-alls of the cup 0, allowing the air to pass in, while at the same time the elastic ring or band B, that covers the outside of the openings V V in the walls of the stem 0', prevents air from passing in through these openings. The downward stroke of the piston B accomplishes the opposite results. The elastic band B closes tight over the openings V V in the walls of the cup 0 while the air is forced out through the openings V V in the walls of thestem c, the elastic band B allowing the air to escape. The only parts that can get out of order in my air-pump are the elastic bands or rings R and It, that form the valves. To repair the pump, it is but necessary to unscrew the bottom plate, 0, and the outlet-pipe E and insert new bandsa manipulation very simple and inexpensive, as elastic bands can be supplied at a trifling expense from nearly every hardware or drug store.
Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-' In an air-pump, the combination, with the cylinder A, having the removable bottom plate, 0, formed withan inverted cup, said cup having openings V, of a rubber band encircling the cup and closing the openings, the hollow discharge-stem 0, formed integral with the cup 0 and projecting downwardly therefrom, said stem being formed with openings V, an elastic band, It, closing said openings, and the discharge-pipe E, removabl y secured to the stem, as set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
HENRY L. BROWN. Witnesses:
THEODORE LANGBEIN, FRANK J. Annns.
