PlSTON-ROD PACKING.

QPECIFICATION forming part of Letters Patent No. 323,320, dated July 28, 1885.

Application iiled September 13, 18554.

To @ZZ whom t may con/cern:

Be it known` that I, JACOB H. GUILEY, a citizen of the United States, residing at East Saginaw, in the county of Saginaw and State of Michigan, have invented certain new and useful Improvements in Piston-Rod Packing,

and I do 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 saine,

reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 'l of the drawings is a vertical sec` tional View of my device. Fig. 2 is also a similar view. Fig. 3 is a horizontal sectional view taken on line x, Fig. 2. Fig. 4 is a vertical sectional view of a modification.

2o Fig. 5 is a horizontal section taken on line yy, Fig. 4;. and Figs. G and 7 are detail views.

rlhis invention has relation to packing devices i'or valve-rods or piston-rods; and its main object is to so construct a packing-box that the gradual wear of said rod will be ett'ectually taken up and the box at all times kept tight.

The invention consists in placing around the valve or piston-rod, within the packing- 3o chamber, a. number of unclosed or longitudinally-cleft rings, which, by nieans of an adjusting' or binding-plate moved up or down by suitable screwsl are niade to close on the rod as it wears.

The invention also consists in the construetion and novel arrangement of part-s, as hereinafter set forth.

In the accompanying drawings, the letterA represents the cylinder-head, and B the pack- 40 ing-box or st1iiing-boX,coniposed of the body or cylinder b, outer covering-plate, b', and inner plate, b, screwing int-o the open inner end of the cylinder I). This cylinder has its outer end closed by the plate b immediately within the covering-plate I1', both plates being provided with central circular openings for the accommodation of the piston-rod.

o is a ch ainber formed by equally rabbeting or otherwise cutting away the meeting edges (No model.)

of the piston openings in the plates b and b3, 5o said chamber containing the waste or wicking.

The plate b2 is rabbeted or otherwise properly formed at its edge, meeting the cylinder-head, so as to be fitted snugly into a suitably-shaped opening inthe latter, and provided around its central piston-opening with apertures b5 b5, by which steam may be admitted from the cylinder 'to the packing-chamber.

The covering-plate b is held to the packingbox and the lat-ter to the cylinder-head by the stud-bolts c c, which pass through proper lugs or extensions on said plate and on the plate b3, and screw into the cylinder-head.

D is the piston-rod, passing through proper openings in the plates b b2 b3, and surrounded 6D within the packing-chamber bythe slitted rings d and d. Said rings are of about equal lengt-h, the ring d lying to the rear of or below the ring d on the piston-rod, and having its end abutting against the surface of the plate b2, while the outer end ci' the ring d abuts against a ring hereinafter more fully described. The cleft openings of said rings extend longitudinally, and are set diainetrically opposite to each other.

E represents a cleft or unclosed ring iitting over the rings d and d', and having its outer surface beveled from within outwardly. Its inner narrower end abuis against the surface of the plate b,while its outer end abuts against the ring, hereinbefore mentioned. The longitudinal opening or cleft e ofthe ring E has its inner narrower end adjacent to the plate b2, and is thence beveled outwardly to its other end,for a purpose hereinafter mentioned. The cleft e is set at right angles to the cleft in the rings d and d', as shown. A stud, e', is provided on the inner surface of the tube E, and designed to fit into notches of the meeting edges oi' the rings d and d. By nieans ofthe stud said rings have their openings held in relative. position.

F is a ring provided with acircnlar central opening for the passage of the piston-rod, and `having its upper or outer dat surface lying 4against the plate b3 and its lower ci rcularl y concave surface iitting over the rounded ends of the tubes E and d. In this manner a balland-socket joint is formed of sufficient extent to insure the close working of the ring and tubes on the rod, even when the latter runs slightly ont of line, and thus prevent leakage of steam.

G is an adjusting or binding plate provided with a central opening beveled to receive and accommodate the tapered tube E, and having formed on the edge of said opening the wedgesh'aped pin g, which is suitably beveled to enter and spread apart the edges of the slit e when the adjusting-plate moves downward.

H H are similar adjusting-scre\vs,wl1ich are situated on opposite sides ofthe packing-case, and are equidistant between the screws c c. The screws H H pass nnthreaded through openings in the plates b and b3, and are provided with circular lugs h h, which may be made to abut or bind against the latter plate. These screws H engage the adj Listing-plate G by threaded openings7 and have their inner rounded ends bearing against the plate b2, as

shown. rllhe outer threaded ends 7L of the screws I-I engage the nuts h2, and by this means the lugs h are drawn close against the plate b3. rllhe ends of the screws beyond the nuts are squared, so that the screws may be turned to move the plate G upward or downward.

A modification of the device is shown in Figs. 4 and 5 of the drawings. In this case one of the screws H and the adjusting-plate are omitted, and the ring E is formed with its outer surface straight instead of tapering, a wedge-piece, I, engaged and actuated by the remaining screw H entering the cleft@ of said tube. The ring E is kept central against the unequal pressure of the piece I by means of the vertical springs J ,whose ends bear against said ring, and whose central portions are pressed inward by the adjustingscrews K, which pass through the sides of the cylinder.

If the packing-box is for a valve-rod, the letter A would indicate the proper plate of the steam-chest. rIhe entire device is adapted to be used in connection with a piston-rod or valve-rod, actuated by water or otherwise, or by steam. v

,The mode of operation is as follows: As the rod D wears, and it becomes necessary to bring the rings cl d closer upon it, the adjusting-plate G is drawn upward by the screws H H, allowing the wedge-piece g to rise into the wider part of the cleft e, and the opening in the adjusting plate then acts on the beveled surface of the ring E, driving it inward upon and closing the rings d and d. The bevel of the surface of the tube E, being the same as the bevel of the slit e, prevents binding in the action of either of these parts. In the modification the closing is eifected more by the spring or elasticity of the ring E; but it is assisted by the action of the springs J Having described this invention, what I claim, and desire to secure by Let-ters Patent. is-

l. In a stuffing-box, the combination, with the plates b', b2, and '193, the rod D, and the elettrings d, d', and E, of the adjusting-plate G, having the wedge-piece to enter the cleft of the said rings E, and screws H, adapted to operate substantially as specified.

2. In a stufng-box, the combination, with the plates b', b2, and b3, the rod D, the cleftrings d, d', and E, and the screws c c, ofthe adj Listing-plate G, the ring F, and the screws H, substantially as specified.

3. In a stufiiing-box, the combinatiomwith the plates b', b2, and b3, the rod D, and the cleft-rings d, d', and E, of the adjusting-screws H, having the squared ends h', and nuts IL, substantially as specified.

In testimony whereofI affix my signature in presence of two witnesses.

JACOB H. GUILEY.
