Specification of Letters Patent.

Patented June 18, 1907.

Application filed Nove ber 7,1906. Serial No. 342,340.

T on whom it may concern:

Be it known that I, JOHN HALTERMAN, a citizen of the'United States, residing at Portland, in the county of Jay and State of Indiana, have invented a new and useful Stuffing-Box, of which the following is a true and com lete specification.

y resent invention relates to a stuflingbox ,eing designed, more particularly, for operation in connection with the olish-rod of oil-Well pumps, or other vertical y moving istons.

My object, broadly s eaking, is to provide a simple, practical, and self adjusting device for packing reciprocatory pistons or the like, which will require only a minimum of attention, giving a maximum of efiiciency, and

which can be manufactured and sold at a com aratively low price.

ore specifically, my object is to provide a stufling or packin -box forthe polish-rod of .course of the ensuing s oil wells or the like, in which the packing material is held at a practically uniform pressure by gravity, and to provide means for easily replacing the packing material when worn-out, and to soconstruct and combine the several detail and essential elements as to give the highest degree of mechanical efficiency.

Other particular objects and advantages of this invention will be made apparent in the pecification, as that which s new will be pointed out in the appending claims.

The construction of my invention is most clearly visualized in the accompanying two sheets of drawings, in which- Figure -1 is a side elevation of my invention complete, and in operat ve position, in connectlon with a portion of a polish-rod Fig. 2 is a top plan view of same, showing the polishrod in section; Fig. 3 is a central horizontal sectional view of same, as if taken on the line Z Z of Fig. 1; F'g. 41 is a central vertical section of same, as if taken on the line XX of Fig. 2; Fig. 5 is a detail isometrical view of the upper portion of the follower and its hanger-arms and Fig. 6 is a detail section of a portion of one of the hanger-arms, as taken on the line YY of Fig. 5.

Similar indices denote like parts throughout the several views of the two sheets of drawings.

In order that my invention may be the more fully understood and appreciated I will tightened in order to retain I now take up the description thereof in detail, in which I will describe the invention and its intended operation asbriefiy and as compactly as I may.

In the drawings the letter A designates an ordinary vertically reciprocatory olish-rod, being such as is generally employed in pumping-oil-wells or the like.

The numeral 1 designates the body portion of my device, which may be termed the receptacle,saidbody is round in cross-see tion, and is cup-shaped, having an inside chamber Whose diameter is considerably greater than is the diameter of the polish-rod Which asses through it longitudinally and centralfy. Closing the lower end of said body is the hexagon nut 1 having a central aperture therein through which neatly passes the polish-rod; and extending down from said nut is the exteriorly threaded lip-portion 1 which is of less outside diameter than is the nut 1 and it also having a central aperture for the polish-rod. The body 1, the nut 1, and the portion 1 should be formed integral with each other as is indicated in Fig. 4. Said threaded portion 1 is adapted to be screwed into a coupling or other fitting which may be on the upper end of the well casing or tubing in which the polish-rod operates, the nut 1 aflording means whereby it may be the body rigidly in contact With the well-casing or tubing.

The numeral 2 denotes the body of the follower which is of an outside diameter only slightly less than is the inside diameter of the body 1, and it is of a length equal to the depth of the receptacle formed in the body portion 1. Extending out around from the upper end of the follower 2 is the flange 2 whose outside diameter is equal to the outside diameter of the body 1. .An aperture is formed longitudinally and centrally through the follower 2 which aperture is alined with said apertures in the .nut 1 and the member 1 as is indicated in Fig. 4, Extending out horizontally from opposite points of the flange 2 are the oppositely disposed hanger- arms 3 and 4, same be ng substantially cardioid in cross-section, having an upper sharp edge longitudinally thereof as shown in Fig. 6. Located at the outer end of each of said hanger-arms is an upwardly extending lug 3 and 4, respectively, for the pur ose resently stated.

E rten ing out centrally from one side of IIO the body 1 is the hanger 5 having an aperture in its outer portion for the horizontally disposed bolt 6. I

The numeral 7 denotes the beam, or weight bar, on which is adjustably mounted the weight 8, the latter being secureable at any point along the length of the beam by means of the set-screw 9. As the beam 7 approaches near the body 1 it divides into two segmental branchesforming the prongs 7 and 7 which extend around the body 1 but some distance therefrom as shown, and terminating each in a finger, 7 a and 7 respectively, which latter are parallel with the bar and contacting with the opposite sides of the hanger 5,there being eyes formed through said fingers to receive the bolt 6, whereby said beam is pivotally mounted and whereby its free end may be raised andlowered to the limits substantially as shown.

Extending out from each of the prongs 7 and 7 on a line with the center of the polishrod, are the respective oppositely disposed arms 10 and 11, similar in form to the arms 3 and 4 directly below which they are located respectively, but having their sharp edges located on their under sides, that is oppositely disposed to the edges of said arms 3 and 4. At the outer end of each of said arms is formed a downwardly extending lug, as the respective lugs 10 and 11, for the purpose presently appearing.

The numerals 12 and '13 denote links, each having a relatively large eye in both their upper and lower ends, as is indicated in Fig. 1, .each pair of eyes being connected by a curved portion or shank as shown in Fig. 4. The link 12 may be so placed that the upper eye thereof is disposed around the arm 3 with the lower eye thereof disposed around the arm 10 and in like manner the link 13 may be so placed that the upper eye thereof is disposed around the arm 4, with the lower eye thereof disposed around the arm 11. After the above it will be seen that when the beam 7, and the weight 8, is free then the plunger 2 will be held in the receptacle of the body portion by the gravity of the weight 8,

as indicated in Fig. 1. When the device is assembled as shown it is apparent that by reason of the lugs 3, 4:, 10 and 11, the links 12 and 13 may not inadvertently be removed, and only after the beam 7 has been raised sufiiciently to allow the links to pass said lugs.

The letter B designates a small quantity of ordinary packing material contained in the receptacle of the body portion, and this packing 1s compressed into position by the lower end of the follower as indicated.

Operation: In operation the nut 1 and the threaded portion 1 close the upper end of the well tube with the polish-rod A operating vertically therein. In order to prevent the fluid being pumped from being forced up around the polish-rod the receptacle of the body 1 has deposited therein a quantity of packing material, and in order to retain the packing material under pressure the follower 2 is forced down into said receptacle, the beam 7 being raised up to allow the links 12 and 13 to be engaged with said arms as shown, and then the beam being released the weight 8 may be adjusted at any point desired on the beam whereby the weight will constantly press the packing B around the polish-rod and the weight will compensate for the wear of the packing as it wears away by the action of the polish-rod therethrough. Desiring to renew the packing B one has only to lift up the beam 7, remove the links 12 and 13, and

then slide the follower up the polish-rod,

thereby giving access to the receptacle.

Having now fully shown and described the best means now known to me for the construction of my invention, I desire that it be understood that various changes and modifications may be made in the invention without departing from the spirit thereof and without sacrificing any of the advantages of the invention.

What I claim and desire to secure by Letters Patent of the United States, is

In a stuffing-box, the combination of the body adapted to be secured on the upper end of a well tubing and containing a packing cavity around the polish-rod operative in said tubing, a follower ada ted to surround the said polish-rod and to fill said cavity, a beam extending out beyond the said body and having prongs to surround the body,

means for pivoting said prongs to the body onthe side opposite said beam, arms extending out from the top of the follower, arms extending out from said prongs of the beam, a link for connecting each pair of said arms, a weight adjustably maintained on said beam, and means for retaining said links on said arms when the pressure of the weight is exerted, all substantially as shown and described and for'the purposes set forth.

In testimony whereof I have hereunto signed my name to this specification in the presence of two subscribing witnesses.

JOHN IIALTERMAN.
