Description

UNITED STATES CHARLES J. JACKSON, OF PLAINFIELD, NEW JERSEY.

VALVE.

Specification of Letters Patent.

Patented July 16, 1907.

Application filed June 16, 190B. Serial No. 265,324.

To yall, whom it may concern:

Be it known that I, CHAaLns' J. Jackson, a citizen of the United States, and a resident of Plainfield, in

i and more particularly to that kind or character thereof generally `known and referred to as a blow-0E cock, adapted for use for boiler blow off, water column blow-off, and which may also be employed between check `and boiler, and between water column and boiler, the objectibeing to provide a device of this character which shall be simple and economical in construction, effective in use, and wherein the plug may be easily and readily adjusted or tightened in the body or casing, or entirely removed therefrom.

With these and other ends in view, the invention consists in` certain novel features of construction and combinations of parts, as will be hereinafter fully de scribed and pointed out in the claims.

In the accompanying drawings Figures 1 and 2 are sectional views of my improved device. Fig. 3 is a view in perspective of the detached plug. 4 is a similar view of the bushing. Fig. 5 is a detached view of the screw employed for the purpose of removing the plug and bushing from the body. Fig. 6 is a sectional view showing my improvement as applied to an angle valve.

Referring ,to the drawings, 7 represents the casing or body of the,valve, provided with inlet and outlet ports 8 and with a central chamber to contain the plug,

. the bottom 9 of said chamber being somewhat depressed and provided with a sleeve 10 into which is `threaded the adjusting screw 11. The walls of this chamber slightly converge toward the bottom, in order that'the bushing 12 contained therein may be easily andy readily forced out of the same. This bushing 12, made in fthe form of a hollow truncated cone, and of any` desired material, such as metal, vulcanized asbestos, etc., has its outer walls converging toward the lower end in conformity with the shape of the chamber in which it is contained, its inner surface converging towards its upper end, as clearly illustrated in Figs. l,2 and 6, it vbeing materially thicker at its upper end than at its lower end.

In Fig., 3, I have illustrated in perspective the plug or valve proper 13, made in the form of atruncated cone, its lower end being of larger diameter than its upper end, and made with a valve opening 14 therein, a stem 15 `extending outwardly from its upper or smaller end and having the extreme end thereof squared to fit a `wrench or other tool, by means of which the lsame is turned in the casing to open or close the valve.

This plug is contained within the bushing 12, and nicely fitted therein to prevent the escape of steam between said plug and bushing, the taper of said plug corresponding to that of the inner surface of the bushing, the latter, however, being provided with a number of slits, holes or openings 17, if desired, for containing a lubricating substance or compound, such as graphite, grease or heavy oils, etc., and also if desired, with a groove or channel 18 leading from its upper edge to the opening 19, whereby oil or other lubricating substance may be supplied between the surfaces of said plug and bushing to insure the easy turning of the former within the latter. l,

Within the bottom of'the chamber formed in the body is contained a plate or disk 20, provided on its edge with the upwardly extending flange 21, which when the parts are assembled, bears against the lower edge of the bushing 12', said plate or disk being also provided with a central opening for the passage of the restricted end 22 of the adjusting screw 11, the extreme end of which latter bears against the lower end of the plug 13.

On the upper end of the body or casing are formed the ears or lugs 23, to which is bolted the plate 24, the

latter being provided with the lugs 25 adapted to bear upon the upper edge of the bushing 12 and tightly and securely hold the latter in its proper position within the body.

In assembling the parts, the plug 13 is inserted in the bushing 12, these two parts being then inserted within the body, the disk 20 having first been properly placed within the lower end of the chamber. The bushing is then forced down tightly in the body and the plate 24 bolted or otherwise secured in place, the lugs 25 thereon bearing on the bushing and preventing any movement ofthelatter. The screw l1 isthen inserted inplace and turned until its restricted end 22 bearing against the r lower end of the plug, will force the latter up tightly in the bushing until the same becomes steam tight therein. By reason of the lubricating substance with which the perforations in the packing are filled, the plug may be easily and readily turned, to open and close thevalve. If, however, it should become stuck, or wedged tightly within the bushing and rendered incapable of being turned therein, the screw 1l may be slightly turned outwardly, and by a slight tap of a hammer, wrench or other tool, on the end of the stem 15, it will be slightly forced downwardly in the bushing, readily yielding to the blow by reason of its coneshape, whereupon it may be easily turned to open or close the same, the screw bcing subsequently turned up to hold the plug in its proper position.

When it is desired to take the valve apart, it is simply necessary to remove the plate 24, and substitute the screw 26, shown in Fig. 5, for the screw 11. The en d of this screw 2G will, when turned home, bear upon the disk or plato 20, and by forcing the same upwardly by moans oi' tho screw, will torce the bushing outwardly l'rt'nn the body. It will be understood, of course, that in order to rcinove the bushing, it is necessary only to slightly start it outwardly by means of said screw, after which it may be easily and readily lifted out of the body by moans of its flaring wall or surface.

In Fig. G, I have shown my improvements as applied to an angle valve or cock, wherein 27-28 represent the inlet and outlet ports ofthe body or casing 29, the wall ot the casing slightly converging toward the lower end, as in the case of the device above described. In the casing is inserted the bushing 30, also shaped and formed like that shown in Fig. 4, with the exception, of course, of the location of the port or opening 3l. In this bushing 30, is contained the plug 32, provided with the angle port 33, and ot the shape of a truncated cone, its lower end being larger than its upper end, the latter being provided with a stem, and squared at its extreme end 34.

To the casing is secured the plate 35, provided with threaded screw openings 36, registering with similar threaded openings 37 formed in the upper end of the bushing and adapted toreceive screws (not shown), said plate being also provided with lugs 38 to bear upon the wall of the body'or casing, and also upon the upper edge of the bushing 30, in order to hold the latter down tightly in place.

When it is desired to remove the bushing, the plate 35 ot Fig. 6 is detached and reversed, whereupon the circumfcrential flange 39 formed on said plate, will bear upon the upper edge o the body or casing. By means ot the screws (not shown), threaded in the openings 36 and 37 'the bushing may be then slightly raised or started from its position in the casing 29, whereupon by removing the plate, it, said bushing, with its contained plug, may be readily lifted out of the body or casing.

It will be understood from the foregoing that my invention is exceedingly simple, and unlike the valves or cocks now commonly employed, it may be easily and readily taken apart whe'n desired, is so constructed and arranged that the plug is capable of being easily and readily adjusted lengthwise in the bushing so as to render the same steam tight therein, and that there is but little or no danger ofthe same becoming stuck or tightly wedged in the bushing.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A blow-od cock having in combination a body provided with inlet and outlet ports, a bushing contained in position in within said body and having thc outer surface of its walls converging toward one end, moans carried by tho body adapted to bear against the larger cud oi' tho bushing to seat Suid bushing, a cone-shaped plug contained within the bushing having.: its outer surface convergingr oppositcly to the outer surface of the bushing, uwaus for movingr the plug` lengthwise :1nd scaling.: it in lilo bushing, nml lucuns adapted to engage the smaller ond of the bushingr lo unseat the bushing.
