PISTON-PACKING.
SPECIFICATION forming part of Letters Patent No. 228,420, dated June 1, 1880.
Application filed April 8, 1880.
To all whom it may concern:
Be it known that I, WILLIAM M. THoMP` SON, Jr., of Barnharts Mills, in the county of Butler and State of Pennsylvania, have invented a new and Improved Piston-Packing, of which the following is a specification.
The invention consists in wrapping the packing-rope of a piston on a taper from the mid dle toward each end, so that it may be more readily inserted in the barrel and drawn out without catching on the tube-joints.
In the accompanying drawing a side elevation, onehalf in longitudinal section, is shown. Y
Similar letters of reference indicate correspending' parts.
Referring to the drawing, A represents the hollow cylinder formingthe barrel ofthe valve, having screw-threaded ends. On the lower end is screwed a sleeve, a. Above this, for about two-thirds of the length of the barrel A, is the packing I3. It is composed of manila or hempen rope wound spirally about the barrel, swelling at the center and tapering toward each end. I/Vhen the wrapping of the packing is completed the lower sleeve, a, is screwed up tightly against it, so as to hold the end of the rope, and at the upper end the sleeve I) is slipped down over the barrel against this end oi' the packing, holding the upper (Model.)
end of the rope. The ballcage C is then screwed on the end of the barrel against the sleeve l), pushing it lirmly down against the packing vand securing all the parts together, as clearly shown in the drawing.
The valve is used in the ordinary well-known manner by attaching it to a sucker-rod operated by a walking-beam.
The packing will be found very efficient, as it makes ,a very close but sufficiently elastic connection with the working-barrel. It is easily applied to the piston-barrel, and cannot get loose and embarrass the working of the pump.
I am aware that it is not new to arrange a packing on a piston between metallic sleeves, so that by turning the pistonfrod the packing may be compressed; but
What I claim islhe combination, with hollow barrel A, baving end sleeve, ,working on its screw-threaded end, of the packing-rope B,wrapped about it and tapering toward each end, the loose sleeve b, and the screw-cage O, as and for the purpose specified.
