` FLOAT-VALIVE.I

Specification of Letters Patent. Application filed March 2f), 1906. Serial No. 307,126.

Patented July 31, 1906.

To all whom it indy concern: .l H-Be it known that I, ERNEST FRIEDRICH,

' a citizen of the United lStates of America, re-

siding at Holyoke, in the. county of Hampden and- State of Massachusetts, have invented new and useful Improvements in (Float- Valves, of which the following is a speciiication.

This invention relates to pulp-valves for use in pa er-mills for directing the flow of pulp in di erent directions from one machine to another, or from one part of the building to another, as may be desired. It is generally used to control the pulp` after leaving the beating-engine and before it enters the paper-making machine.

Broadly, the invention consists in securing a valve or gate to a horizontally-movable shaft in the valve-casing, so that the flow of pulpl can be changed from a horizontal direction to one at ri ht angles thereto, or,` vice versa, as may be desired.

In the drawings forming ,part of this application, Figure 1 is a side elevation showing the valvein dotted lines in longitudinal adjustment. Fig. 2 is a longitudinal sectional view on line 2 2, Fig. 1, showing the valve in full lines thrown to a vertical position and to a horizontal position in dotted lines. Fig. 3 is a section on the line 3 3 of Fi 1 looking in the direction of the arrows an showin the valve in vertical adjustment in dottedv ines. Fig. 4 is a horizontal sectional view looking downward on the line 4 4 of Fig. 3.

Referring to the drawings in detail, c desiglnates 'a portion of the main pulp-pipe; b, t e valve-casing, secured to the pipe cb by the ordinary flange-and-bolt construction, as shown.

c designates a plate for covering an opening in the top of the valve-casing b for affording means for inspecting and repairing theinterior of the valve mechanism. This plate is secured lto the casing b by the thumb-nuts d.

The ends of the plate are slotted or cut away, as shown at e, so that the plate can be easily removed or inserted in place by simply unscrewing one of the thumb-nuts. p

Extending transversely of the casing b, and in the lower side thereof, is a shaft f, to which issecured by solderingor otherwise the valve g. The lower side of the casing b is made ilat where the valve g rests, as shown at g. Secured on the outside of the casing and to the transverse shaft f is an operating handle or lever It for throwing the valve g into a vertiing, and means for attaching lcal or horizontal position. On the interior of the casing and extending around the inner wall thereof is .a vertical fian e fi, ,against which theV valve g rests when t rown into avertical position, as clearly shown in Figs. 2,

3, and 4. I

It will be noticed that the lower side of the casing has aV pipe j connected at right angles to the casing b, as shown in Figs. 1, 2, and 3.

The valve g when turned into a horizontal position forms a closure for the passage-way 4leading from the casing b to the pipe j, and

when in this position the valve gis flush with the bottom of the casing, as shown at 7c, Fig. 2. The valve g rests on a horizontal flange m, as shown in Fig. 4, for supporting the valve when in this position.

In order to securely hold the valve g in 4either a horizontal or vertical position, I havpivotally mounted on the outside of the casing b locking-latchesn and o. In the op osite sides of the handle 7L are cut two noto es p and g in a iece 1^, that is riveted to the operating-hand e h, as shown in Fig. 3. When the handle h is thrown, and consequently the valve g, into a vertical osition, the latch n is rotated to the dottedine position, so as to engage the notch p in the piece 1, thus securely holdingthe valve in this position, andV when the same is thrown into a horizontal position (shown in dotted lines in Fig. 1) the atch o is rotated, so as to engage the notch g. (Shown in full lines in this figure.) It will therefore be seen that the valve g is securely locked in either-horizontal or vertical position, according to the direction in which it is desireld that the pulp is to flow. When in the position shown in Fig. 2, the pulp is diby the arrows 8,) and when thrown into a horizontal position, as shown in the dotted lines of Fig. 1, the pulp can pass freely through the pipe a and the connecting valvecasing b, as indicated by the arrows t.

'Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, isn 1. A pulp-valve mechanism, a valve-casthe same to a p1 e at either end, a manho e in the upper sil e of the. casing, and means for closing the same, a transverse shaft in the lower side of the casing, va valve attached to the shaft, a handle secured to one end of the transverse shaft, pivotal latches secured to the outside of the casing and adapted, when the valve is IOO y IIO in either a vertical or horizontal position, to engage the operating-handle to lock the saine in said position.

2. In a pulp-valve, a casing, the lower portion of which is strai ht, the remaining portion being substantia ly a curved surface7 a transverse shaft extending through the casing and mounted lin the straight portion thereof, a pipe secured t0 the casing at right angles thereto and adjacent to the transverse shaft and communicating with the interior of the casing, an operating-handle secured to the transverse shaft and having notches therein located opposite each other7 pivotal latches mounted on the casing for engaging the notches to lock the operating-handle in either a vertical or horizontal position so that the How of pulp may be permitted to pass freely through the valvecasing when in a horizontal direction, or be deflected from the casing in a direction at right angles thereto and through said pipe.
