WILLIAM E. BEACH, or MASON CITVYQIOWA.

SAFETY NON-OLO GABLE STEAM AND WATER COCK.

Specirication of Lettersyatent. :Patented July 31, 1917.

Application filed February 24, 1914. Serial I To. 820,649.

To all whom it may concern Be it known that I, XVILLIAM E. BnAoH, a citizen of the United States, residing'at Mason City, in the county of Cerro Gordo and State of Iowa, have invented certain new and useful Improvements in Safety Non-Clogable Steam and lVater Cocks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The primary object of'this invention is to provide an extremely simple and practical steam and water cock for boilers.

Another and more specific object of the invention is to provide a cock of this nature having a long hollow cylindrical body which may be threaded at one end into a boiler, a valve stem extending longitudinally through said body having a plurality of scraper blades and a valve formed integrally on the.

inner end thereof for engagement with a valve" seat formed in the body, and means carried on the valve stem and closing the outer end of the body, saidmeans when in operative position causing the valve stem to move longitudinally when rotated, and when in inoperative position allowing the stem to be rotated without longitudinal movement.

With these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a longitudinal sectional view through my improved. cock, showing the same partly in elevation and attached to a boiler,

Fig. 2 is a section taken on the plane of line 22 of Fig. 1, and

Fig. 3 is a transverse section taken on the plane of line 33 of Fig. 1.

Referring in detail to the drawings by numerals, 5 designates the elongated hollow body of the cock, having its inner end portion externally threaded, as indicated at 6, for attachment to a boiler or other receptacle, having a wall 7 The inner end of the body is contracted in diameter and shaped to form a frusto-conical valve seat 8, and the body is enlarged intermediate its ends, as indicated by the numeral 9, to afford a grip to a turning tool, such as a wrench.

The outer end of the body is externally threaded, as indicated by the numeral 10, and is engaged by a cap nut 11 having an interior flange 12. This nut is for the purpose of attaching an internally threaded sleeve or bonnet 13 to the body 5. The sleeve projects into the body, as indicated by the numeral 1 1, and is formed with an annular flange 15 having its inner face beveled for engagement with the'beveled edge 16 of the body. The outer side or face of the flange 15 is flat and is engaged by the flange 12 of the locking nut. When the nut is tightened on the body, the sleeve isheld against rotation. and forms a tight joint.

A valve stem 17 extends longitudinally through the sleeve 13 and body 5, is formed on its inner end with a valve 18 for engage ment with the seat S,'and intermediate its end is provided with a plurality of longitudinal series of scraper blades or spurs 19, the blades inone series being arranged in staggered relation with respect to the blades of the adjacentseries, "When the stem 17 is rotated,"the blades 19 which engage the interior of the body, scrape therefrom all deposits and the latter are discharged through a pipe 20 threaded into a discharge opening 21 in the lower side of the body ad j acent the outer end, but the sleeve may be readily released and run back on the stem to afford access to the enlarged portion or chamber of the body for cleaning the same and removing any scrapings accumulating in the said chamber. It will be noted that the body is diametrically enlarged near its outer end to form a chamber 22 so that the material scraped from the interior of the body will not clog at the entrance to the pipe 20.

The scraper blades also act as guides to hold the valve 18 in line with the valve seat 8 in the end of the body 5.

hen the nut 11 is tightened so as to hold the sleeve 13 against rotation, and the valve stem rotated by a hand wheel 22 or other suitable operating member, the stem will move longitudinally according to the direction of rotation. lVhen the stem is turned so as to move inwardly, the valve 18 will be unseated, allowing steam or water or both to flow through the body 5 and discharge through the pipe 20.

N ow when it is desired to grind the valve 18 in the seat 8, so as to securea perfect fit and prevent all leakage, it is only necessary to loosen the cap 11 to allow the bonnet 13 to be moved away from the beveled edge 16 of the body 5. lhen the stem may be turned to grind the valve against its seat. It will be noted that this operation may be carried out while the boiler is under pressure without any leakage of steam or water. 28 designates a hexagonal cap nut threaded onto the outer end portion of the sleeve or bonnet 13, so that the latter may be turned by means of a suitable tool;

From the foregoing description taken in connection with the accompanying drawings, itv will be apparent that I have provided a very simple and practical non-clogable steam and water cock, having a valve which may be ground in its seat without necessitating the removal of the device from connection with a boiler and without allowing an escapeof steam or water.

While I have shown and described the preferred embodiment of my invention, it will, be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed. 4

Having thus described my invention, I

claim V A device of the character described comprising a hollow elongated body having a valve seat at its inner end, a valve stem eX- tending through the body and provided at the inner end with a valve to engage the said seat, a plurality of longitudinal rows of spaced scraping blades carried by the valve stem, said blades being rectangular and extending radially from the stem with their outer ends in engagement with the inner face of the hollow body, said rows of blades being relatively spaced and the blades of one row being arranged in staggeredrrelation with the blades of the adjacent rows and having a width exceeding the width of the spaces between the blades of the said adjacent rows so that the blades of one row will overlap the blades of the adjacent rows to scrape the entire inner surface of said body during rotary and longitudinal movement of the valve stem, said body being provided near its outer end with an enlargement forming an enlarged chamber to receive the scrapings, and means for detachably connecting the valve stem with the body, said means including a cap nut threaded on the outer end of the body, and a sleeve detachably secured to the outer end of the body by the cap nut and having a threaded engagement with the valve stem, said sleeve and cap nut being adaptedto afford access to the chamber for removing the scrapings.

In testimony whereof I aiiix my signature in presence of two witnesses.
