PACKING DEEP-WELL PUMPS.
SEEGIFECATEON forming part of Letters Patent No. 318,447, dated May 26, 1885.
Application filed June 520, 1884.
T0 coZZ whom it may concern.-
Be it known that I, HENRY M. CAMPBELL, a citizen of the United States, residing at Bay City, in the county of Bay and State of Michigan, have invented a new and useful Improvement in Packing Deep-\Vell Pumps, of which the following is a specification.
Heretofore when the packing in deep-well pumps required tightening it has been necessary to take all the tubing, well-poles,and pump out of the well, at considerable eX- pense, trouble, and loss of time, in order to get at the pump to tighten the packing therein.
The object of my invention is to provide a means by which the packing in these pumps can be tightened in a few minutes time at veryslight expense and without removing the pump from the well. I attain this object by the mechanical device set forth in the annexed drawings, in which- Figure 1 is a side view of a deep-well pumpbarrel, stufiing-box, and plunger, with one side left off to show the flexible packing and my device for tightening the same. Fig. 2 shows a section of the plunger to the pump with my improvement of collar and lugs forged thereon. Fig. 3 is a top View of my improved follower or gland. Fig. 4 shows a vertical section of the said follower.
Like letters refer to like parts in the several views.
In Fig. 1, F represents a pump-plunger in pump-barrelE, passing through stuffing-box a and flexible packing G, also through follower 0. This plunger F is made of wroughtiron, and forged With the collar B and lugs c 0 all in one piece, with orifice 5 through top, where the water escapes into tubing D, and with thread e run on its top, for connection with poles leading to the top of well.
(No model) C is a brass gland or follower, fitting closely around plunger F in stuffing-box a. It has slots (1 d cut in opposite sides of its top, and is held firmly in position by and runs in a thread cut on the inside of stuiiing-box a. The plunger F ordinarily works with the collar B above the stufiiug-box a; but when it becomes necessary to tighten the packing in stuiiingbox a the plunger F (connected with poles leading to the top of well) can be lowered sufficient to let lugs c 0 drop into slots d (I, when by means of a wrench or clamps in the hands of an operator at top of well the follower 0 can be screwed down on and tighten the packing in box a, after which the plunger F may be raised to its former position and the pumping proceed as before.
Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-
1. In a deep-well pump, the projecting collar B, provided with lugs c c in connection with plunger F, having orifice b and thread 6, for the purposes specified.
2. In a deep-well pump, the combination, with stuffing-boxa and flexible packing G, of the follower 0, provided with slots d d, for the purpose set forth.
3. In a deep-well pump, the combination, with collar B and lugs c c, of the follower O and slots d d, all substantially as shown, and for the purpose specified.
In testimony whereof I have affixed my signature in presence of two witnesses.
