STUFFlNG-BOX.
'im rovements in stuffing-boxes for pistons,
va ve-rods, and the like, and it particularly contemplates the provision of novel'means for su plying liquid lubricant to the iston.
In t e art as commonly practiced lu ricating material of a semisohd consistency has been employed which contains more or less grit. In the course of continued use the small particles of grit adhere to the piston in its reciprocating movement, and friction is generated betwen these, articles and the lands or packing-rings the stuffing-box. he friction thus'generated Wears away the surface of the piston and the acking-rings and impairs t e efficiency 0. the engine, pum or other device in connection with whic the piston is emplo ed.
It is the primary eonsid eration of the present invention to reduce to a minimum degree the friction in the stuflingbox due to gritty lubricants, and thus elimlnate the disadvantages above noted, and to this end the invention'resides in the provision of a lubricating means with which liquid lubricant, which is almost wholly freefrom grit, may be employed.-
The detail construction will appear in the course of the following description, in which reference is had to the accompanying drawings, forming a part of this specification, like numerals designating like parts throughout the several views, wherein- Figure 1 is a longitudinal section showing a stuffing-box embodying the present invention. Flg. 2 is a side elevation on lubricating-ring constructed in accordance with my invention, and Fig. 3 is a top plan view thereo l I have shown my invention as emplo ed in connection with an engineiston, an m the accompanying drawin s t e numeral 1 .'5
designates an engine-cylin er, within which the piston 2, carried upon the piston-rod 3, has movement. The end late 4 of the engine-cylinder, through whic the rod 3 passes, 1s provided with a depending collar 5, concentric with. said rod and formed at its base .With an outstanding; annular flange 6. A

packing-gland 7, formed at its base with an annular outstanding flange 8, occupies the space between the rod 3 and the collar 5, and said gland is adjustably seated in said s ace by virtue of its connection with the col ar 5 extending ,through' the flanges 6 and 8.
The gland 7 is formed with an inclined 1 per edge 7", which serves to. center the ac mg-rings a ainst the-piston. These ac gringsare esignated by the numera and occupy in su er'imposed relation the concentric space etween the collar 5 and rod 3 above the gland 7. The means for supplying li uid lubricant to the piston comprises metal ic ring 11, surrounding the iston and inter osed between the end wall 0 the collar 5 an thev uppermost of the rings 10. The
end wall of the-collar 5 is concaved, as at 5,
and the ring ll'is formed with a convex up per surface 11, designed to rest in the con-,
cave seat 5 therefor, and with a concave lower surface 11*, againstwhich the uppermost of the rings 10 bears, the surfaces 11 of the ring 11 and 7 of the gland 7 cooperating to center the rings 10 against the iston.
The ring 11 is formed with groove sides 11 and is accordingly substantially X- shaped in cross-section, so that concentric spaces 12 and 12' are left, respectively, between said rin and the collar 5 and between said ring and t e rod 3. t
The spaces 12 and 12 serve as reservoirs for the reception of liquid lubricant, and communication is had therebetween by providing the ring 11 with a series of'o enlngs 11?, extending transversely throu h t e narrowest portion ofsaid rin an arranged apart at regular intervals of istanoe.
The collar 5 is-formed with a series of 0 enings adjacent, the openings 11, into W ch are threaded lubricant-conductors 13, ro-. vided with lock-nuts 14, and throu h w ich the lubricant flows under pressure rom...the
source of supply.
In practical use the liquid lubricant, such as water or oil, is introduced through the conductors 13 into the space 12, from whence it flows as required through the openings 11 into the space 12, where it is consumed in actual use. The supply of lubricant is constant, and as long as main'tamed under the requisite pressure the feed thereof is auto-. 'matic. It will thus be seen that I have rovided a device which (possesses the functions of the expensive an complicated oil-cups IIO one whic 5 claimtherein surrounding said r0 conimonlyemployed with shafting, and yet is exceedingly simple and inexpensive to manufacture.
Having fully described my invention, I
. The combination with a longitudinally W movable rod, of a stuffing-box,
surrounding e same and comprisinga cylindrical casing formed with anopen end, said rod passing I0 centrally through said casing,
packing-rings a lubricatingring therein adjacent to the closed end of said casing, vsaid ring being formed with a con" cave underneath surface and a gland adjustably secured to said casing and formed with a concave upper surface.
In testimony whereof I afliX my signature in presence of two witnesses.
