UNITED f STATES PATENT Oerle ROBERT H. MOONAND JAMES H. BAKER, OF SPRINGFIELD, ILLINOIS.
STEAM-ACTUATED vALvE.
SPECIFICATION forming part of Letters Patent No. 263,193, dated August 22, 1882.` Application led April 20, 1882. (No model.) Y l To all 'whom it may concern Be it known that we, ROBERT H. MOON and JAMES H. BAKER, citizens of the United States, and residents ot' Springfield, in the county7 of Sangamon and State ot'lllinois, have invented a new and valuable Improvement in Steam-Actnated Valves; and we do hereby declare that the following is a full, clear, and exact descriptionof the construction and operation ofthe same, reference being had to the anncxed drawings, making a part of this specification, and to the letters and figures ot' reference marked thereon. V
Figure l is a vertical longitudinal sectional view of our steam-actuated valve. Fig. 2 is a vertical cross-sectional view of the same. Fig. 3 is an end elevation of one ot' the heads. Fig. ltis a side elevation of the main valve, and Fig. 5 is la side elevation ot' one of the heads detached from its stem.
This invention has relation to steam-actuated valves; and it consists in the construction and novel arrangement of parts, as will be hereinafter vfully described and specifically claimed.
In the accompanying drawings, the letter A designates the valve-chest, having the steamsupply a and the ports b and c.
B represents the reciprocating valve-stem, and O C the heads thereon, between which the main valve D, which is loose on the valvestem, recprocates. In each `head is made a recess or chamber, d, from which a passage, e, extends to the inner side of the head, serving to convey steam, when received fromthe port b, to the inner side ot' the head, where it acts to move the valve D toward the opposite head. In each head is also made a channel or recess, g, to receive steam, which is conveyed by a hole or passage, h, through to the outer lace of `the head, or rear thereof, for thevpurf pose of cushioning the head at the end ot' its movement. Exhaust -passages It and L are made in the steam-chest to allow the steam to exhaust after lithas moved the main valve D. The interior ot' the valve-chest, the main valve, and the heads are usually cylindrical in form, being so designed in preference, in order that the bearin g surfaces may Wear evenly and that the main valve may constantly change its bearing.
main valve stem B, and when the motion of the stem has caused one of the heads to move,
bringing its recess or Vchannel d into communication with the port @sufficient steam is allowed to pass from said port b through the recess or space d and the passage e to move vthe main valve toward the opposite head,
thereby reversing steam in the cylinder. While this is the action at one end, at the other the movement of the stem causes the recess or channel g ot the head to pass over` the port b, allowing enough steam to enter said. channel or recess g and pass through the hole or passage h to the rear otl the head to cushion the same. v Y I In the movements of the main valve D, the flanges F pass over the exhaust-passages 7c, stopping the exhaust, and causing the main valve to slacken its motion and conne up slowly and cushion against the head O, the concaviry in the end of the valve allowing the steam to expand. Before the cushioning ot' the main valve the exhaust-steam passes from the hole k vinto the space K, and thence ont through the passage m.
Havingdescribed thisinvention, what wedesire to claimand secure by Letters Patent is- The steamactnated valve consisting ot' the reciprocating stem B, the heads G, secured thereto, andV having the stealnways d -e g h,
and theloose flanged valve D on the stem,`
substantially as specified.
In testimony that we claim the above we have hereunto subscribed our naines in the presence ot two witnesses.
ROBERT H. MOON. JAMES H. BAKER.
