UNITED STATES PATENT OFFICE.
GEORGE HILL DIOKSON AND JOHN DICKSON, OF BROOKLYN, NEW YORK.
PACKING FOR PISTON-RODS.
QPECIFICAI'ION forming part of Letters Patent No. 332,793, dated December 22, 1885.
Application filed September 8, 1885. Serial No. H6535. (No model.)
To all whom it may concern:
Be it known that we, GEORGE HILL DICK- soN and J OHN DIOKSON, of Brooklyn, in the county of Kings and State of New York, have invented an Improved Packing for Piston- Bods, Valve-Stems, Plungers, and Analogous Devices, of which the following is a specification.
The invention relates to packing piston-rods, valve-stems, plungers, and analogous devices, so that they may be rendered water and steam tight.
The special object of the invention is to combine metallic rings with expansible packing, so that the former will press the latter in the middle and cause a wedging action, which will expand the packing toward both the rod and the packing-box.
Figure 1 of the drawings is a Vertical section showing the application of my invention. Fig. 3 is an end and side view of a ring which is V- shaped on one side and round on the other. Fig. 2 is a similar view showing a ringwhich is V- shaped on both sides. Fig. 4 is a similar View showing a ring which is rounded on both sides.
In the drawings, A represents a piston-rod; B, the packing-gland; '0 D, the screw-clamp by which the gland is held and adjusted, and E the packing-box. The box E has an upper flange, e, which receives and supports the screw 0.
A A A are wedge-rings of metal or other solid material, and B the expansible packing. The vertices of the wedge angles of rings are made to bear upon the middle of the packing, so as to press it in opposite directions, The rings A A being respectively placed at top and bottom require but one side to be angled or wedge-shaped, while ring A, which is arranged intermediately, is constructed with two opposite angles or wedges for pressing an upper and lower packing. The upper side on the rings A A may be rounded, as shown, or made of any other shape adapted to facilitate an equable pressure. The rings are cut diagonally in halves by preference.
Our invention is used as follows: The ring A is first placed in the bottom of the packingboX E, and an expansible packing, B, hammered down upon it. Then asecond packing is hammered down upon this. The double ring A is then put in position, and-on this is superposed two more packings, B, when the top ring, A, is placed upon them. The packing-b0x gland B is now screwed down upon ring A, and the packing expanded to the desired extent.
We are aware that angle-rings of solid metal have been combined with angle-tubes; but the latter consist of wire wrapped about an inner tube, the angles of the solid metal meeting between the angle-packing; hence they cannot give the wedge pressure in the middle of packing, as ours do.
Having thus described our invention, what we claim as new, and desire to protect by Let; ters Patent, is-
lhe packing B, combined with the wedgerings A A A and a clampinggland, substantially as and for the purpose specified.
