IMPROVEMENT IN THE CONSTRUCTION 0F MOLAVSSYES-GATES AND COCKS FOR DRAWING LIQUORS.

Specification forming part of Letters Patent No. 2,342, dated November 10, 184i; Reissue No. 105, dated January 25, 1848.

'- clear, and exact description of the principle or character which distinguishes them from all other things before known, and of the manner of making, constructing, and using the same, reference being had to the accompanying drawings, making part of this specification, 1n which- Figure lis a perspective view of the said improved gate for drawing molasses and thick liquids or semi-fluids;` Fig. 2, a like represen- Vtation of one intended for drawing water and f other thin iuids, and Fig. 3 a like representation ofthe valve-lever reversed to exhibit the passage through which the liquor is discharged.

AThe same letters indicate like parts in all the figures. y In my improved gate or cock thedeliveryaperture is opened and closed by a sliding valve at the end thereof, which makes part of alever that turns on a fulcrum-pin, a segment-plate being used in combination therewith to keep the said lever-valve against the faeeof the delivery-aperture and prevent leakage; and when the said gate or cock is used for drawing thin liquors, the lever-valve y thereof is formed with a projection or lip in front,in which the delivery-aperture is formed to give the liquid a downward direction ask it leaves the instrument.

The nature of my invention in the said in-v strument consists in combining with the levervalve of a stop cock or gate that turns on a fulcrum-pin a segment-plate so connected with the lever as to cause it to make pressure ,against the end of the delivery-aperture of thescrew-tube, and thus resist the outward plessure of the contained liquid and prevent eek age; and m invention alsol consists in forming the sai valve with a projecting lip in front, in which is formed a delivery-spout 'togive a downward direction to the liquid as it issues from the main or screw tube. In the accompanying drawings, b represents the. main or screw tube of the cock or gate,

| made in the usual manner, except that at the forward endlit is formed with a projecting tube, and on one2side this iange extends out in the form of an arm, and to the outer extremity thereof the end c of the lever-valve d is secured by a screw, i, which forms the fulcrum on which the valve turns. On the opposite side the flange is formed in the segment of a circle to receive two screws, g h, that secure asegment-plate, f, over the valve to keep it up against the delivery end of the main pipe, which may be lined with a ring of leather, e, over which the valve slides. By turning the screws g h the pressure of the segment-plate f on the lever-valve can be increased or diminished at pleasure, to increase or decrease the pressure ofthe face. of the valve against the end of the main or screw tube, thus insuring a close joint which will resist the outward pressure of the liquid and avoid leakage. The segment-plate f is the segment of a circle of which the fulcruln of the levervalve is the center. When the lever-valve is turned down by taking hold of the outer extremity, which should have the form of a handle, the lower edge of the valve gradually closes the aperture, and in doing so cuts oli' all the liquid which\might otherwise hang about the aperture, particularly with the thicky luids, such as molasses; but when the instrument is intended for drawing thin liquorssuch as water- Which would y out ofthe main tube horizontally, the valve is formed with a -lip or projection, k, in which is formed a curved hole, Z Z, that passes from the inner face to thelower edge of the lipin form somewhat like a quadrant, to deiiect the liquid and give it a downward direction.

Instead of the quadrant-hole Il, the inside of the lip may be cut out entirely to form simply a recess, the outer part of which will deiiect the liquid and turn it downward. When made with the quadrant-hole, where the hole passes through the face of the valve, it should be so situated as to correspond with the aperture of the main tube when the lever is thrown the part of the face of the valve which lies opposite the main tube when closed.

It will on reection become apparent that the segment for keeping the valve against the iange, a, at right angles with the axis of the up. The dotted circle m, Fig. k3, represents face of the main tube may be variously arranged without varying the purpose for which it is used or the principle of this part of my invention-vas, for instance, instead of the segmentplate f, the lever of the valve can be formed with a projecting lip that will embrace the segment part of the ange a, and there provided with a set-'screw Or spring which will draw the face of the valve againt the end of the tube; or, instead of the lip embracing the segment-ange, the ange may be made with a segment-slot, through which a screw attached to the vvalve can pass and move as the valve is opened or closed, a screwnut being used belowthe flange to make the required pressf ure; or, instead of this, the segmentplate may be placed on the opposite side of the fulcrumpin,and the lever of the valve extended to it, with a temperscrew Or strong spring to make pressure on the segment, and thus press the face ofthe valve against the end Of the main tube. It is believed that these modifications will be sucient to show the variety of changes lents thereof, substantially as herein described,

whereby the valve can be made with a close joint to resist the outward pressure of the contained liquid.

2. Forming a lip on the Valve with 'an ap-. erture or recess to deflect the liquid and give it a downward direction, when this is ccmbined with the main tube that discharges horizontally, as herein described.
