50 aZ Z whom it may concern.-

Be it known that I, RUFUs E. BALL, a citizen of the United States of America, residing at irosperity, in the county of Jasper and State of Missouri, have invented new and useful Improvements in Mineral-Gates, of which the following is a specification.

This invention relates to a novel and improved mineral'g-ate or valve for controlling the discharge of minerals from steam jigtanks, the object of the invention being to provide a valve of this character which is simple of construction, reliable and eflicient in use, and adapted to effectually withstand the wear to which valves of this type are subjected by the action of the outflowing mineral,

and, further, to provide a mineral-valve in which provision is made for securely retaining the valve-gate in closed position and adjustably mounting the same to compensate for wear and permit of its ready renewal when occasion requires. The valve may, however, be employed for various uses, and especially in places where devices of this kind are subjected to excessive wear.

The preferred embodiment of the invention is illustrated in the accompanying drawin s, in which igure' 1 is a side elevation of the improved valve, showing the sliding gate closed. Fig. 2 is a longitudinal section of the same, showing the gate opened. Fig. 3 is a bottom plan view of the body of the valve. Fig. 4 is a section through the head of the valve-body, the gate, and the guiding and adjusting clamp, taken on the line 4.- 4 of Fig. 1 and Fig 5 is an outer side elevation of the sliding gate.

Referring now more particularly to the drawings, the numeral 1 designates the body ofthevalve,whichisgenerallyofconventional form, being provided with an exteriorlythreaded inner or inlet end 2, adapted to be screwed into the outlet-opening of the jigtank, and a polygonal portion 3 adjacent thereto for the application of a wrench or similar tool to apply and remove it. The body is outwardly and downwardly curved from the said inlet end and is formed with a make the body of some suitable hard chilled metal 12nd de art from conventional constructions by gra ually increasing the thickness of the walls of the ;body toward its outlet end,

thus adapting it to be used for a considerable period before discardure is required. This construction causes the production of a head 5 .of increased area at the outlet end of the body, the outer face of said head being-arranged obliquely to the end 2 and finished to form a smooth seat for the sliding velvega'te 6. The area of the head is further increased by forming the body at its outlet end with an upward extension or prolongation7, whose outer surface is flush with and prolongs the length or extent of the seat-face. Formed in the head at the base of the outletpassage '4 a recess or socket 8, coextensive with the lower half of the outlet end of said passage, and in this recess or socket is inserted a segmental wear-strip 9, composed of some hard highly-endurable metal, thus forming a hardened lip or wear-surface at the point where the metal discharges to protect the body of the valve from the excessive wearing action of the metal at such point. This wear-strip is held in position by a set-screw 10 and when worn may be readily removed and a new strip substituted therefor. By this means the body of the valve will be relieved to a large extent from the abra-ding action of the outflowing metal, and its period of usefulness will thereby be considerably prolonged.

The head 5 is provided at its sidee'dges with guide-flanges 11, formed at their lower ends with inwardly-extending stoplugs 12. Slidably engaging these flanges is a valveattaching device or clamp 13, comprising a yoke having its body portion 14 extending transversely across the head and its arms 15 projecting inwardly and formed with guide recesses 16, engaging the flanges 11, and inwardly-extending flanges or extensions 17, which engage and ride upon the inner faces of the flanges 11, thus slidably connecting the yoke thereto, the downward movement of the yoke on the flanges 11 being limited by the stop-lugs 12. The space between the arms 15 of the yoke is suflicient to receive the gate 6, which is in the form of a plate adapted to fit closely against the seat-face of the head and to be adjusted and clamped in adjusted position by the yoke. This valve-plate is provided at its lower end with an outer rib or thickened portion 18, which serves as a bottom stop to hold the valve in engagement with the yoke and also as a reinforce to thicken the lower end of the valve to adapt it to more effectually sustain the wear thereon caused by the action of the outfiowing metal as the valve is being moved to its open posi tion. Above the rib 18 the valve-plate is provided on its outer side with a series of holding-lugs 19, said lugs and ribs being spaced equidistantly apart to an extent s'uf ficiently to receive the body portion of the yoke in the spaces between them. The said body portion of the yoke is formed with up per and lower inwardly-extending flanges 20, forming a chamber 21 to receive a bowed pressure-spring 22, having its ends arranged to bear against the outer surface of the gate and hold it seated against the seat-face of the The tension of this spring and its consequent pressure on the valve-plate may be regulated by a set-screw 22, carried by the yoke.

Owing to the fact that the lower end of the valve-plate contacts with the hardened wear-strip 9 and is also subjected to the abrading action of the outflowing metal at the outset in its opening movement, it will be readily understood that this portion of the valve is rapidly worn away, and it is necessary when sufficient wearing away has oc curred to adjust the valve downward on the yoke to adapt its lower end to come when closed farther below the upper face of the wear-strip to obviate any liability of leakage from imperfect contact between the same. Thus when the lower end of the valve becomes worn upon detaching the valve and yoke from the head the valve may be slipped farther downward until the lower and middle lugs of the set of lugs 19 come below and above. the respective upper and lower flanges 20 of the yoke to lock the plate thereto, so that when these parts are reapplied the valve when closed will seat downward to a further extent on the face of the head 5, thus maintaining a perfect closing contact with said face. In this manner the valve may be repeatedly adjusted to avariety of positions, according to the number of lugs used, so that it may be employed for a considerable period before it becomes necessary to discard the same and substitute a new valve-plate. In the initial application of the valve to the yoke the body of the yoke lies between the rib 18 and lower lug 19, thus connecting the valve with the yoke for adjustment to open and close the passage 4. To facilitate the adjustment of the yoke and valve, a suitable grip or handle 24 is applied to the body of the yoke.

In order'to limit the upward movement of the valve and prevent possible disconnection of the same from the head 5, a stop-screw 25 is provided upon one of the flanges 11, with which the yoke 13 is adapted to contact when the valve is raised to its fully-open position. This screw may be detached when it is desired to remove the yoke and valve for the purpose of adjusting the latter to compensate for wear or to substitute a new valve therefor. The extension or prolongation 7 increases the length or depth of the seat-face of the head 5 to the necessary extent to compensate for the wide range of adjustability of -the valve, as will be readily understood.

By the construction above described a valve is provided in which the portions most subject to wearare adapted to readily sustain the abrasive action ofthe outflowing metal for a comparatively long period and to be renewed or adjusted when occasion requires to render the valve-body susceptible sity of discarding the valve-body at the end of the ordinary period of use and adapting it to be employed for a much longer period before its discardure is necessary. A valve of this type will therefore render longer service andbe less expensive of installation in the long run than valves of ordinary construction,

dustry.
