This invention relates to certain improvements in pum s, and more particularly toan improved pac ting ring or cup especially designed for use in connection with pump-pistons for oil-wells.
In pumps of this type experience has demonstrated that when the ordinary leather, canvas, or rubber packing-rings are employed the action of the sand, grit, and other foreign matter usually elevated with the oil has a tendency to cut or otherwise injure the cups, so as to render them practically unfit for use after a short period of service; and the primary object of my invention is to provide means for protecting said cups whereby their period of usefulness may be materially prolonged and the elliciency of the pump proportionally increased.
The invention consists in surrounding the packing rings or cups with a metal protecting strip or band, preferably in the form of a split ring, the adjacent ends of which are spaced a short distance apart to thereby permit the expansion and contraction of said cups, and thus insure the necessary frictional contact with the pump-barrel, while at the same time effectually preventing undue wear and cutting of the packing-cup by the action of the sand and grit.
The invention further consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in form, proportions, and minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.
In the accompanying drawings, forming a part of this invention, Figure 1 is a longitudinal sectional view of a portion of an oilpump, showing a plurality of packing-cups constructed in accordance with my invention applied thereto. Fig. 2 is a perspective View of one of the cups detached. Fig. 3 is a similar view showing a modified form of the inve ntion.
Similar numerals of reference indicate cor responding parts in all the figures of the drawings.
Referring to the drawings, 5 designates the pumpbarrel or tubular lining of an oil-well, in which is mounted for reciprocation the hollow piston 6, said elements being of the usual construction and forming no part of the present invention. Mounted on the piston 6 and retained in position by the usual clamping-collars 7 are my improved packing rings or cups 8, the latter being preferably formed of leather, although canvas, rubber, or other flexible material may be employed in the construction of said cups, if desired. Surrounding the vertical walls 9 of the cups and disposed flush with the upper edges of the latter are metal protecting-bands 10, preferably in the form of split rings, the adjacent ends of which are spaced apart, as indicated at 11, so as to permit free expansion and contraction of the cups, and thereby insure frictional engagement of said cups with the interior walls of the barrel 5.

The metal bands 10 are preferably secured to the cups by means of rivets 12, while the adjacent ends of the band are inclined or beveled, as shown at 13, so as to present a smooth and practically continuous metallic surface to the pumpbarrcl, and thereby pre vent sand, grit, and other granular material usually elevated with the oil when pumping the latter from cutting or otherwise injuring the leather or other flexible material forming the body of the cup. The protecting-bands preferably terminate a short distance above the bottom of the inwardly-extending flanges 14 of the cups, whereby any expansion of the leather when clamping said cups in position or the piston will not affect the metal bands.
In Fig. 3 of the drawings there is illustratcd a modified form of the invention in which the metal band is formed in two sections 15 and 16, the adjacent ends of which are also spaced apart, as shown at 17, to permit the necessary expansion of the packingcups.
From the foregoing description it will be seen that there is provided an extremely simple and inexpensive device admirably adapted for the attainment of the ends in view.
Having thus described the invention, what is claimed is 1. A packin -cup for pump-pistons comprising a flexib e body portion provided with an inwardly-extending flange for engagement with the pump-piston, and a split ring secured to and surrounding the exterior walls of the body portion, the adjacent ends ofthe ring being spaced apart to expose a portion of the flexible body portion and inclined or beveled in opposite directions.
2. A packing-cup for pumppistons comprising a flexible body portion provided with an inwardly-extending flange for engage ment with the pump-piston, and a split metal ring secured to and surrounding the exterior walls of the body portion with its adjacent ends spaced apart and inclined or beveled in opposite directions, the upper edge of the ring being disposed flush with the top of the body portion and its lower edge terminating short of the bottom of the inwardly-extending flange.
In testimony that I claim the foregoing as my own I have hereto affixed my signature 111 20 the presence of two witnesses.

Creating a proper plunger alignment is critical for correct flow and a long wear life. Stuffing box components are of stainless steel, brass or other application-specific materials. Gland A gland is a general type of stuffing box, used to seal a rotating or reciprocating shaft against a fluid.
The most common example is in the head of a tap where the gland is usually packed with string which has been soaked in or similar grease. The gland nut allows the packing material to be compressed to form a watertight seal and prevent water leaking up the shaft when the tap is turned on. The gland at the rotating shaft of a may be packed in a similar way and graphite grease used to accommodate continuous operation. The linear seal around the of a double acting steam piston is also known as a gland, particularly in marine applications. Likewise the shaft of a handpump or is sealed with a gland where the shaft exits the borehole. Other types of sealed connections without moving parts are also sometimes called glands; for example, a or fitting that connects a flexible electrical conduit to an enclosure, machine or bulkhead facilitates assembly and prevents liquid or gas ingress. Applications Boats.
A small boat stuffing box comprising an adjusting nut, a locking nut and a sleeve. On a boat having an inboard motor that turns a shaft attached to an external, the shaft passes though a stuffing box, also termed a 'stern gland' in this application. The stuffing box prevents sea water from entering the boat's hull. In many small boats, for example, the stuffing box is mounted inboard near the point the shaft exits the. The 'box' is a cylindrical assembly, typically of bronze, comprising a sleeve threaded on one end to accept adjusting and locking nuts. A special purpose heavy-duty rubber hose attaches the stuffing box to a stern tube, also called a shaft log, that projects inward from the hull. Marine-duty secure the hose to the stern tube and the stuffing box.
A sound stuffing box installation is critical to safety because failure can admit a catastrophic volume of water into the boat. In a common type of stuffing box, rings of braided fiber, known as shaft packing or gland packing, form a seal between the shaft and the stuffing box. A traditional variety of shaft packing comprises a square cross-section rope made of or impregnated with wax and lubricants. A turn of the adjusting nut compresses the shaft packing.
Ideally, the compression is just enough to make the seal both watertight when the shaft is stationary and drip slightly when the shaft is turning. The drip rate must be at once sufficient to lubricate and cool the shaft and packing, but not so much as could sink an unattended boat. The market offers improved shaft packing materials that aim to be drip-less when the shaft is turning as well as when stationary. There are also pack-less sealing systems that employ engineered materials such as carbon composites and (e.g.
