WATERMHAWlh/i-ER PREVENTIVE.V
SPECIFICATION forming part of Letters Patent No. 312,882, dated February 24, .1885.
Application filed August 14, 1884. (No model.)
To @ZZ whom it may concern:
Be it known that I, FERDINAND L. MEN- TEL, of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Vater-I-Iammers, which improvement is fully set forth in the following specication and accompanying drawings, in Which- Figure l` is a vertical longitudinal section of my improved water-hammer. Fig. 2 is a perspective view ot' the tube which is attached to the water pipe; Fig. 3, a perspective view of the elastic cushion in contact with the water; Fig. 4, a perspective view of the tube forming the air-chamber; Fig. 5, an elastic cushion for the air; and Fig. (i is the tube forming the air-chamber and head of the device.
The object ofL the present invention is to providea new and improved water-hammer for pipes, so arranged that the water, in gaining admission to the tube device, comes in contact with an elastic cushion, which cushion has on its opposite side an air-chamber, the opposite end of which chamber has a secondary elastic cushion backed by a secondary air-chamber, so that the force ofthe water as it strikes the main cushion is counteracted, not only byv the elastic cushion, but by the two independent air-chambers, all of which will now be fully set forth in detail.
In the accompanying drawings, A rcpresents the main tube, which is attached to the water-pipe either by means of the threaded end B or by soldering to the waterpipe, as may be most convenient. Centrally is an aperture, C, which may or may not conform with the size of the water-pipe to which it is attached. The opposite end of this tube is cnlarged exteriorly, as shown at D, and provided within with an enlarged portion, so as to forro an annular seat or shoulder, E. rI'he one rim is screw-threaded, as shown at F, to receive the tubular part H, Fig. 4. Au elastic cushion, G, is placed in the opening, so as to rest upon the shoulder E, and the tubular part H ,having its end I reduced and screwthreaded, is designed to be screwed into the end oi' the tube A, so that it will bind the cushion G snugly in its seat. The opposite end of the intermediate tube, H, is provided with a similar socket and seat, J, to receive a rubber cushion, K. The end is also screwthreaded, as shown at K', to receive the head or Acap L. The cap L is hollowed within, as shown at M, so as to provide an air-space similar to the air-space N in the intermediate tube, H. The inner end ofthe cap L, which abuts the cushion K, is preferably concaved, as shown at O, so as to provide for compres-4 sion of the cushion K.
Then the water enters the tube C, which iirst moves inwardly, the elastic cushion G in turn imparts pressure to the cushion K through the intervention ofthe compressed air within the chamber N. Thus the two independent air-chambers N M receiveihe force or impact ofthe water in quick succession, and prevent the blow ofthe water upon the pipe.
Having described iny invention, what I claim is l. A water-hannner consisting of the screwthreaded tubular section A, the screw-threaded hollow cap L, the intermediate screwthreaded hollow section II, and the two elastic cushions confined in said sections and forming two air-chambers, substantially as described.
2. A waterhammer composed of three screw-threaded sections connected together, as described, the elastic diaphragms therein, and the two air-chambers, as specified.
3. In a water-hammer, the combination of the tube A, adapted to be attached to a water-pipe having at its opposite end of the attachment, within a suitable recess, an elastic cushion, the intermediate tube, H, having an air-chamber, N, and the cap or head L, having asecondary chamber or air-space, M, with the elastic cushionsG K, as and for the purposes substantially as herein set forth.
In testimony that I claim the foregoing I have hereunto set my hand this 17th day of July, 1884, in the presence of witnesses.
FERDINAND L. MENTEL.
