.TACK GRANT, OF FORESTBURG, TEXAS;

PACKING,

To all whom it lmay concern: Y

Be it known that 4I, JACK GRANT, al citizen of the United States, residing at Forestburg, in the county. of Montague and AState of Texas, have invented new and useful Iniprovements in Packings, of which the following isa specification.

This invention 'relates to -a packing intended primarily for use where a reciprocatory. element asses into a chambered body, and is especia ly applicable for-windmill or similar pumps wherein the rod is likely to have a lateral movement simultaneously with its longitudinal movement due to vibration and the like. f

4The invention has for one of its objects to provide a packing of comparativel Simple and inexpenslve construction, rel1ab e 1n use,

and composed of comparatively few parts.

.Another object of the invention is the prov1s1on of a packing consisting of a conical flexible tube such as canvas, which has one end secured to the reciprocatory rod and the other end attached to the casing, whereby a perfect seal is provided which at the same j time permits reciprocatory and lateral movement of the rod.

With these"objects in view and others, as fwill appear as the description proceeds, the inventlon-comprises the various'- novel features of construction and arrangement vof parts which .will be more fully described hereinafter and set forth with particularity in the claim appended hereto.

f In the Vaccompanying drawing, which illustrates one embodiment of the invention, Figure 1 is alongitudinal sectional view of the upper end of a pumpcasing having the packing 4ap lied to the ump' rod of the casing, the ro being in its owermost position. Fig.

' 2 is a similar view showing the rod in raised p position.

Referring to the drawing, 1 designates a casing, such for instance', as the upper end which is arranged t e reciprocatoryeplun ger rod 2, the rod extending through a pack- Specification of Letters Patent.

that such changes mayl or the like and in Patented oct. 2o, 190s,

ing A. This packing comprises a hollow conical body disposed withln the casing l in inverted position, the said body belng made 'of canvas or other flexible water-holding material. The lower end of the body A has a neck 3 which snugly fits the pump rod l and is secured thereto by a split clamping ring 4.- or other equivalent means and the upper end of the packing projects out of the casingand is turned downwardly to lap over the` outside 'of the casing, and sur rounding this forwardly-turned portion 5 is a band 6 that clamps the packing to the casing. The packing is of suitable length to permit the rod to have itsnormal movement without undue'strain on the clamping devices 4 and 6, and when the Vrod is in its lowermost. point, the packing assumes the position shown in Fig. l, and when the rod 1s raised, the packing is collapsed like a bellows, as shown in Fig.v 2. The packing forms-a perfect seal so that water cannot escape out of the casing around the rod and at the same time the rod can have a limited Athe method of operation will be readily apparent to those skilled in the art. to which the invention appertains, and wh1le I have described the principle ofoperation of the invention, together with the devices whlch I- now .consider to be the best embodiment thereof, I` desire to have it understood that the device shown is merely illustrative, and be made when de sired as are within t e scope of the appended claim.

` Having thus described the invention, what t Iclaim isz- 1 The combination of a casing, a reciprocatory rod extending. longitudinally therethrough, a flexible hollow packing within thecasing tapering in one direction and having an opening at its smaller end to fit i the rod, a rind embraoin" the smaller end doubled-back art of the ackng for clampe g p P of the packing to yclamp the same rigidly ing the latter to the casing. to the rod, said casing having an opening In testimony whereof I affix-my signature in which the larger end of the packing ts I in presence of two Witnesses. y

and the said larger end being bent out- Y. JACK GRANT. wardly and backwardly on itself to embrace Vitnesses: the outside of the easing adjacent the openl J. W. BOWERS, ing thereof, and a ring fitted around the T. J. CATHRAN.
