AROHIBAL S. NELSON, OF GONNEAUTVILLE, PENNSYLVANIA, ASSIGNOR OF ONE-HALF HIS RIGHT TO HIRAM F. HAMMON, OF SAME PLACE.
IMPROVEMENT IN SLIDE-VALVES.
Specification forming part of Letters Patent No. 144,282, dated November 4, 1873; application filtd June 3, 1873.
To all whom it may concern:
Be it known that I, ARCHIBAL S. NnLsoN, of Gonneautville, county of Crawford and State of Pennsylvania, have invented certain new and useful Improvements in Slide-Valves, of which the following is a specification:
The nature of my invention relates to an improvement in slide-valves; and consists in making two extra openings in the valve-seat, and two extra openings through the valve, by this device increasing the means for the quick introduction of steam, giving a full opening at one-eighth of the stroke; also, in avoiding friction and expense by the simplicity of construction and few parts of my device.
Figure 1 is a longitudinal section of my invention. Fig. 2 is a plan of the valve.
1 represents the valve-seat, having the usual receiving and exhaust ports 2 and 3, and en haust-portei, and, in addition thereto, the receiving-ports 5 5, opening into the ports 2 and 3. The valve 6 is an ordinary slide-valve, having two extra openings or ports, 7 8, corresponding to and operating in conjunction with the two ports 2 When the valve is open, as shown in Fig. 1, both the opening 8 and extra port 5 admit steam, which is conveyed by port 3 to the cylinder. At the same time the valve 6 closes the remaining extra port 5, and opens the port 2, for the purpose of exhausting steam.
The advantage gained is the quick introduction of steam into the cylinder by the simultaneous opening of the two valve.
By my arrangement of ports in the valveseat and valve, a given amount of space is open in one-half of the time, and by the valve traveling one-half of the distance-that is to say, an opening of five-eighths (*2) of an inch is produced, by means of the two openings, by the movement of the valve five-sixteenths of an inch.
It will be observed that the port 2 or 3, as may be required, is ample for the purpose of exhausting the steam. The extra port 5, therefore, is closed.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is a a The valve-seat 1, having extra receivingports 5 5, opening into ports 2 and 3, in combination with the slide-valve 6, having two openings, 7 and 8, so placed as to open the ports 3 and 5, or the ports 2 and 5, when takports by a single ing steam, and close the opposite port 5 when exhausting, as herein shown and described.
In testimony that I claim the foregoing as my invention, I hereunto affix my signature this 28th day of May, 1873.
