will!!! p @lill use some means must be rovided for automatically su plying r the lluliricant and for preventing tllie drying:r andV shrinking ol the ruppacking,.and for permittingr the use of such .pump without requiring too great prevision 1n its application and operation.
While I have described a single embodiment of my invention I do not desire to be understood as limiting m invention to`the sie'cifio constructionl disclosed, as consider'- a le latitude of variation may be made from that set` forth without departing from the spirit and scope of my invention.
Having thus described my invention, what I claim and desire to secure liyLetters Patent, of the United States, is:
l; In a pump the combination of a piston, a piston rod for moving said piston, and an annular lubricating medium loosely eneompassing the piston rod. I
2. In a pump the combination of a piston,
apiston rod for moving said piston, a pump liar-rel and an annular lubricating medium in said barrel, loosely encornpassing.,r the piston rod and overlying said piston.
3, ln a pump, a cylinder closed at one end around the piston rod, and at its other end open, the cylinder being of uniform diameter to a point adjacent its open end and at said open end outwardly flared, a piston in the cylinder, the piston rod, a ring of rubber of Haring shape having its smaller end overlying the flaring end of the cylinder, and at its expanded end free and projecting beyond the cylinder, and means for securing said ring upon the cylinder.
In testimony whereof I hereunto set myA hand in the presence of two Witnesses.
