IMPROVEMENT IN HYDRAULIC D'lSKS,

Specification forming part of Letters Patent No. 115,365, dated May 30, 1871.

To all whom it m a4 concerm Beuit known that I, THOMAS SHAW, of the cityand county of Philadelphia, Pennsylvania, have invented a new and Improved Steam i or HydraulicDisk for sustaining the end thrust of heavy-laden revolving shafts; and I hereby declare thefollowin g to be a full, clear, and exact description of the same, reference being had to the accompanying drawing and to the letters of reference marked thereon.

My invention consists in a hydraulic or steam disk for supporting heavily-laden revolving.

shafts, as will hereinafter be more fully set forth and described. a i I The accompanying drawing represents a vertical section of my disk.

a represents a sectionof pipe, which is used when my. invention is applied to a pump. I When used for other purposes this part may tending upward for the support of the bed-- I plate 01. This bed-plate consists of acircular plate, of any desired size, and which has a circular groove,o,cutin its face, and an open-- ing through it so as to'connect the groove, by

means of the pipe a, with a steam-boiler or forcing-pump. h is a shaft,t-o the lower end I of which 'is attached the revolving load, of

whatever kind. Secured to the shaft is a re volving disk, 9, which has a deep groove cut in its bottom, near the outer edge, for the re I ceptionof thepistoneg This piston, being of the shape; shown in the drawing, isv provided with a common packing-ring, Z, and bears on the bed-plate until the pressure from the pump or steam-boiler reaches a certain limit. Screwed into the groove in the disk 9 is a circular ring, 2', which,as the disk is being raised upward by the pressure from beneath, catches underthe inwardly-projecting edge of the piston, and, as soon as the pressure exceeds a de; sired'lirnit, lifts the pistonfrom its seat so as to let the surplus pressure escape into dome 7c, and from thence through the pipe m; Between the ring i and piston 0 there is left sufficient space to allow the pressure from the pipe at to bear downward upon the top w of the piston so as to keep it pressed firmly upon the bed-plate d..

In order that the friction shall not be too great upon the face of the piston as it revolves with the disk a larger bearing-surface is given to the lower end of said piston.

It will be evident that the packing and location of piston can be variously modified without any alteration in the result.

What I claim, and desire to secure by Letters Patent, is-

1. The revolving disk g, provided with an annular piston, e, and ring 2', substantially as described.

2. In combination with the above, the grooved bed-plate d and pipe n, substantially as described.
