SPECIFICATION forming part of Letters Patent No. 470,397, dated March 8, 1892.

Application filed March 21, 1891.

oiling devices to the gland of the stufting-box by means of screws; but this is found to be objectionable 011 account of the expense of construction and on account of its constant liability of working loose and unscrewing from the jar of the engine. Then, again, the

screw-cap is not adjustable, and the oil-hole has to be in one place and cannot be turned around, as the screw has to be set up very tight to prevent its working loose, and as the construction of engines differs the oil-hole in the lubricator has to be placed to suit the location of the guides.

his the object of my present invention to obviate the objections heretofore encountered and to so construct the lubricator that it may be affixed to the outside of the gland of the stuffing-box without the necessity of screwing it in place.

A further object is to so construct a lubricator and affix it to the gland that it may be readily turned, so that the oil-hole may be located at any point desired, whereby the de- Vice may be used on devices of different con.-

structions.

A further object is to produce a lubricator adapted to be secured. to the outside of the gland in such manner that the lubricatingswab may be accessible for repair or renewal without the necessity of loosening or unscrewing the main parts of the gland.

lVit-h these objects in view the invention consists in the combination, with a gland, of a cap located on the outside of said gland, a swab held in place by said cap, and means for holding said cap in place.

The invention also consists in the combination, with a gland, of a cap secured to the outside thereof, said cap beingprovided with Serial No. 385,850. (No model.)

an oil-hole, a lubricating-swab held in place and adapted to be inclosed by said cap, and

means for holding said cap in place; and the invention also consists in certain novel features of construction and combinations and arrangements of parts, as hereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a View of my improvement, illustrating the parts assembled. Fig. 2 is a sectional view of the same.

A represents the gland, and A a piston rod or journal. The exterior face of the gland is preferably recessed for the reception of the flange a of an annular cap B, the body of said cap being made curved in cross-section and adapted to protrude outwardly somewhat from the gland. The cap thus formed is adapted to receive and inclose an annular lubricatingswab C, to which oil is supplied through a suitable oil-hole b, and by means of which the piston rod or journal A is lubricated. A series of four (more or less) screw-threaded sockets is made in the gland A for the reception of headed screws 0, and placed on said screws between the heads thereof and the gland is a series of eccentric washers D,

adapted to normally overlap the flange a of the cap B, and thus hold said cap in place;

By constructing and attaching the device in the manner above set forth it will be seen that it can be turned so as to bring the oilhole in any desired position to meet the exigencies of the case. Then, again, one great point of advantage of my improved lubricator is that it is held on the outside of the gland by means of eccentric washers, so that by one turn of the screws the washers can be turned by which it is secured in place on the gland, this flange having an oil -hole formed therein, substantially as set forth.

In testimony whereof I have signed this I 5 specification in the presence of two subscribing Witnesses.
