Description
tinited gaat @wat @Mite Letters Patent No. 107,062
,dated September 6, 1870.
IMPROVEMENT IN PISTNPACKING- The Schedule referred to in these Letters Patent and making part of the same.
To all lwhom 'it may concern Be it known that I, JOHN KEESEY, of Chester, in the county ot' Delaware and State of Pennsylvania, have invented a new` and useful Improvement in Pis ton-Packing; and I do'hereby declare that the following is a full,clear, and exact description thereof', which will enable others skilled in the art to make andl usc the same, reference being had to the' accompanying drawing forming part of this speciiication.
This invention relates to a new and useful improveincnt in mode of packing the pistons of steam-engines,lwhereby the packing-rings are made self-adjusting, and thc piston is made to work steam-tight in the cylinder; and
The invention consists in a grooved central ring ou the spider of the piston, and in segmental 'packingrings, in combination therewith, as will he hereinafter more fully described.
In the accompanying sheet ot'drawing- Figure 1 is a view of thepiston-end, with the follower off.
Figure 2 is a section of iig. 1, on the line x ft.
Similar letters oi' reference, inidcate corresponding paris.
A is the piston-head.
l; is the spider.
These two parts are cast in one piece, to which the piston-rod G is titted in the usual manner.
D is the follower, which is screwed to the spider, as represented in iig. 2.
E is the grooved ring, which is fitted onto the spider, as seen in tig. 1.
This ring is rebated, so that recesses are left next to both piston-head. and follower. in which recesses the packing-rings are placed.
Une side of these recesses is at right angles with' the liuc ot' motion of' the piston. The sides formed .by the grooved ring E are at any desired angle, for
thc purpose oi' reducing,r the area of' the inner side of the packing-ring, thereby reducing the pressure, and preventing unnecessary friction and wear.
f and g representthe paeking-rings which are cut up' into three or more segments, and placed in the. recesses, as seen in tig. 2'. The rings are turned so as to conform to the shape of the recess, but of' lessdepth and width than the recess, so that the steam will enter behind the. main ring f, as seen' at 71and force the.
rings outward and into proper position.
The segments into which the-ringsf and 'g are cut are placed fin the recess, so Ias to break joints' and prevent steam from passing.
It will be seen that the packing-rings will work loosely in the recesses on'the back stroke alternately, but will be forced out by the pressure of the steam alternately, when the piston is driven in the opposite direction. I represents the grooves in the ring E. The water of condensation will enter these grooves, which will serve to lubricate the piston, or lubricating material, as tallow or other substance, may be placed therein, where it will serve the intended purpose. It will be seen that the packing-rings are scltladjusting, and will adaptthemselves to any irregularities in the bore ot' the cylinder. No time is lost in setting out the packing, while the 'piston works steam-tight, thus reducin;Y friction, and saving botl: steam, time, and fuel.
Having thus described my invention.
I claim as new and desire to secure by Letters Patent- In piston-packing, a spider-ring, E, rebated von each end, combined with two pairs of packing-rings fg, cnt at several points, located as set forth, and operating as and for the purpose described.
JOHN KEESEY.'
