Description
sind @fitta WILLIAM HA'As, v,or NEW YonK'-, N, v,
` Letters Patent No. 112,450, dated March 7, 1871.
` `lMiRovEME-Nr IN sToP-cocKs AND VALVES.
The Schedulereferred` to in these Letters Patent and 'making part of the same.
To all whom it `'motif concern .j
Be, it known that I, WILLIAMHAAS, "ofv the city, county, and State of New York, have invented a new and useful Improvement in `Stop-Cocks and Valves;
and I flo hereby declare the following to he. a full, clear, y and exact description thereof,` which will enable those` skilled in the art `to make and use thesame, reference `being had to the `accompanying drawing form,- ing part of this specification, iuwhichldrawing- Figure 1 represents alvertical section of this invenf tion as applied to `a stop-cock. Figure2 `is a plan ortop view of the same.` 4Similar letters 'indicate corresponding parts;4 l This inventionrelates to stop-cocks, and consists ofacertain arrangement of parts, as will hereinafter he more fullyset forth.` l p 'In the drawing,- y The letter A designates the plug orstop-cock, which is fitted into the `shell B in the usual manner."
Tosaid plug issecured `a` worm-wheel, a, which gears fin a worin, b, mounted or formed on a spindle, c, which has its bearings in lugs d cast with or otherwise Viitrmly connected to the shell B.
e, which serves to rotate the same, and, as the spindle is turned, a slow-but powerful motion is imparted to the'plug A, so that said plug can be opened or closed with comparative ease, even if it works very'hard, or `if it is liable to stick. A
In order to be able to'turn plug A, or .to move the valve G toward or from its seat with sucient speed, the worm b may. be made with a double or triple thread, and the thread on thevalve-spindleE may also be double the operation of my invention.`
What I claim as new, and desire to secure by Letters Patent, is
Y, The plug A of the stop-cock, fitted into `the shell B and carrying the worm a,.arrauged and operating in connection with' the worrn b upon Ythe spindle C, which has its `bearings in the lugs d of the shell B, as herein shown and described.
` WM. HAAS. vWitnesses:
. y W. HAUFF, v
E. F. KASTENHUBER.
On the end of thespindle cis secureda hand-wheel,
or triple. These changes, however, would not change'
