UNITED STATES PATENT OFFICE.
WILLIAM P. STAN-HOPE, 0F CINCINNATI, OHIO, ASSIGNOR TO THE BALDWIN COMPANY, OF CINCINNATI, OHIO.
VALVE-FACING.
Specification of Letters Patent.
Application filed September 29, 1917. Serial No. 194,059.
To all whom it may concern:
Be it known that I, WILLIAM P. STAN- HOPE, a citizen of'the United States, and residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Valve-Facings, of which the following is a specification.
In the application of Robert A. Gally, #186,224, is shown an improved facing and collar of a valve. The present application is an improvement in the attachment of such .a facing to the valve disk.
In the drawings Figure 1 is a plan view, and Fig. 2 an elevation of a rod and valve with the facing of the valve fastened in the improved manner, the facing only being in section.
The valve disk 1 of stifi material has a facing 2 of soft and flexible material, as skiver pneumatic leather laid freely across the entire under face of the disk 1 and brought over the edge of the disk and turned in on the upper face ofthe disk and attached to the disk by any suitable adhesive, as French varnish. The leather facing 2 has a decided tendency to spring away from the upper face of the disk 1, especially when the adhesion is slow to make, as on a metal disk as brass, and if not strongly adhered is likely to come loose after a time. This can be avoided by a scoring in the turned over flat part of the leather facing .2, said scoring 3. extending around the entire valve on a line between the edge of the valve and the inner edge of the turned over part of the facing leather. This scoring 3 does veral things :works casioned by the turning over and inwardly of the leather facing. The score line stiffens the turned over leather into a ring of which all parts help each other to remain in place. When the scoring is made at the time of the said part of the out any of the wrink es oc-. I
joining the facing to the disk it causes a forcing of an extra quantity of the adhesive into, two rings, one immediately at each side of the scoring, thus gaining-an extra adhesion .and stiflening of the leather.
Either a round, oval or polygonal or other form of valve may be made with the present improved scoring of its facing.
WVhat I claim as my invention is 1. A valve and a flexible facing extended over one face of the said valve and around the edge of the said valve and inwardly over and adhesively attached to the opposite face of the said valve, and a scored depression extended into the said inwardly extended part of the said facing and around the said part of the said facing.
2. A valve and a flexible facing extended over one face of the said valve and around the edge of the said valve and inwardly over and adhesively attached to the opposite face of the said valve, and a scored depression extended into the said inwardly extended part of the said facing and around the said part of the said facing, and the said inwardly extended part of the said facing having a raised part immediately adjacent the said scoring.
3. A valve and a flexible facing extended over one face of the said valve and around the edge of the said valve and inwardly over and adhesively sion extended into the said inwardly extended part of the said facing and around said facing, and the said inwardly extended part of the said facing having two raised parts immediately adjacent the said scoring.
