Description
fi gmt@ WILLIAMGLASS, or BROOKLYN, NEW vous..
Letters Patent' No. 109,001, dated November.8, 1870.
IMPROVEMENT IN LATERA-LLYVFSLIDING THRQTTLE-VALYES.
The Schedule rofoncd to in the Letten hunt and making part of the seme.
To all whom *it may concefm.-
Be. it knovvuthat-I, WILLIAM GLASS, ot'.l?-rooky lyn, in the county of .Kings4 and State of New' York, have invented a new and valuable Improve-4 ment in 'Sliding-Valves; and'Ido herebydceia-re that the vfollowing is a full, clear, and exact description of the construction and `operation' of the-same,
reference being had to the annexed drawing making al part of this specification, and to the letters and figures of reference marked thereon.
vFigure l1 of the drawing is al representation of ai central horizontal section of the valve and casing.
.Y Figure 2 is a front viewthereo Myiuvention has relatilonv to au improvement in slide-valves, vand consists ili constructing-a ratchet on the back of the slide, and operating the same by means of a pinion in the valvecasing.
The letter A of the drawing designates the valvecasing made in such form as may be mo'st. desirable to subserve the-purpose intended, and provided with a groove for the operation ofthe valve, as hereinafter mentioned. .l A B represents the valve slide, to which is secured the ratchet-bar G.

' against its seat.
L represents a stuffing-box, through which the piny ion-shaft passes.Y -This smiling-box is used principally when the valve is employed'to regulate the passage-of steam.
or'iiqnds it is not required.
In the operation of my invention it will appear that.
the number of turns of the pinionshaft required to carry the valvesiide from one ,end of its way to theother, depends upon the relation between the number of teeth on the pinion to' that of the teethof the ratch- Usually Ilind it practicable so to regulate these numbers that the full movement of the slideshall be accomplished by less than one revolution of the pin- When used for liquids, as aspigot, the advantage 'of a free passage through the tube is obtained by a comparatively small movement of the handle.
IVedge-shaped lugs, m m, are attached to each side of the slide; and serve, when in contact withthe inclined planes z, to keep. the valve pressed tightly What I claimas my invention, and desire tolsecure by Letters Patent, is- 1 In combination, the slide-valve 15, with attached ratchet-bar O, and wedges m en, the valve-casing A,
with sliding groove's as described, inclined-.planes z, and the pinion D, substantially as specified.
In testimony that I claim the above, I have hereunto subscribed 'my name in the presence of two wit- IIESSBS.,
