To all fwtome't may concern.: I Y.

Be it known that 1, WILLIAM F. llaizeia, a citizen of the United States, residing at St. Paul, in the county ot Ramsey and State ot Minnesota, have invented a new and useful Globefalve, of which the following is a specification.. i

My invention relates to improvements in globe-valves, and the main object is to provide a globe valve with a valve seat which inay readily bev taken out of the valve shell for grinding ,or other repairs. Another object is. to provide a valve with aseat which when it can no longer be repaired may be removed anda new one substituted. These and other objects l attain by the novel construction and arrangements ot parts illustrated in' the accompanying drawing, in .which- Figure 1 is apartly sectional sideelevation ot my improved valve shown as connecting two pipes at right angles ,to each other Fig. 2 is a vertical, central, longitudinal section ot a globe valve embodying my iinlill ' proveniente and so modified that it connects two pipes 'in' linear position.'V lli 3 is a detail top view of the split collar 22 in Referring to the drawing by reterence numerals, d designates piping in which the valve shell 5 is connected, the arrows indieating the direction in which water, gas, compressed air, dec., are supposed to move.

Threaded upwardly into the bottom ot the valve shell isla hpllow base plug 6, the top of which ina-y torni the valve seat 7 in a direct manner. ot the invention the plug 6 inay siinply be removed from the shell each time the valve seat needs grinding. But as it is'a well lrnown tact that an ordinary valve seat aiter being ground a tew times can not be further repaired but rnust be replaced by a new one, 'l further improve the valve seat by -rnalring it separable 'troni plug ti, so it inay be removed and replaced by. a new one whenever so required.

To accomplish' the latter purpose nia-lie the seat in the torni oi a tube 7 having about lower end a iifed collar t3, which collar rits snugly in a cylindrical cavity 2 in the plug t3, and is retained 'therein `by packing 10, a movable collar 11, and a cap 12, the latter threaded upon the reduced portion 13 ot' the plug and havinga central aperture tor the seat-tube Pl'to project upward through.

` threaded into the thirnble.

ln this the simplest 'torna By this arrangement it is obvious'that whenever the tubular ineniber 7 becomes too inuch v `vorn down or otherwise damaged, it may be removed andreplaced by a new one. Said tubular valve seat ineinber is .preferably inade of glass, so as to be cheap and to resist corrosion.

Arranged to close the top of the valve seat is a valve rneinber composed of a soft disk 1d, of leather or rubber, or similar material. Said disk is held between a centrally open inverted cap 15, which is threaded upon a thimble 16, and the bottoin ot said thiinble; said bottoni is provided in its upward side .`with a cavity 17 in which is placed a part ot the ball-shaped portion 18 of. the valve stem 19; the latter being threaded at 2O in the upper member 5 ofthe shell 5 and provided with a suitable handle wheel 21.

The ball 18 is retained in the thirnhle 16 by a dianietrically split collar 22, which is ln ordina-ry valvesthe thiinble y16 is so shallow that 'there is no chance to get a hold of it and unscrew it troni the rne'inber 15, to remedy this detect lt inalre the thiinble with an Unthreaded extension 16a which may be grasped by a pair ot pipe-tongs or other tool so as to torce 'the thiinble loose when it is stuck in the rnernber 15. l

lnv Fig, 2 the water passes through vthe duct 23 and a circular recess 24 inthe shell and through apertures 25 in the base plug, and thence through a central aperture 26 and up into the tube 7 of the valve seat, and when the valve plug is raised the water will ilo-w out ot the top ot the seat and out at the duct 2'?. ln 1 the apertures 25, shown in -Eig. 2, are dispensed with, as the water passes troni the lower pipe t directly up through the aperture 26 and the tube i'. ln Yllig. 1 the pipe la is connected with the valve shell by a nipple 28 and a union 29; said union enables the shell to be detached troni the pipe la and unscrewed trom the base plug t3, so as to reach the seat 'i' for repair or exchange, as already explained, only that in 1the separatin oi the shell and its'base plug involves a little more worlr than i l @di at one end andI threaded into the eap and havingyan internal central cavity in its closed end for a portion of the ball oi' the valvesteni; a diainetrioally divided collar threaded into the thiinble and arranged to retain the ball. of the stein therein; Said thiinble having an externally unthreaded portion projecting above the edges ot the inverted Cap which holds the Soft disk.

2. lin a globe Valve, the Vcombination with. a 'Valve shell having an aperture in its lower side, of a hollow plug threaded upwardly m@afer-Lui into said aperture and a Valve seat detaohablyseeured in the upper end of said pluO; said hollow plug having its upper portion j reduced as to the outside diameter andl threaded, 'and the inner end of the passage therethrough enlarged in diameter, and said valve seat Consisting of a tubular body having its lower end provided with an external fixed collar resting in the vlower end of said enlargement, packing inserted, upon Said collar, a packing collar threaded upon the upper portion of the hollow plug` and having an inward flange bearing upon the packing. ln testimony whereof llaihr my signature.
