JAMES LOWDEN, 0F LINCOLN, NEBRASKA.
PISTON -ROD SWAB.
Application filed August 80, 1917.
T 0 all whom it may concern.
Be it known that I, James G. LOWDEN, a citizen of the United States, residing at Lin (-oln, in the county of Lancaster and State of Nebraska, have invented a new and useful Piston-Rod Swab, of which the followin r is a specification.
l he present invention relates to a swab for use upon piston rods, valve stems and other reciprocating parts working in packings, and it is the object of the invention to provide such a device constructed to lubricate the rod or stem whereb it will work smoothl in the packing witliout injuring the pee ing, as is the case when the rod or stem becomes dry, and the device will also, in being used adjacent to the packing, prevent sand, grit and other foreign matter from reaching the acking.
It is the ob ect 0 the invention to provide a swab of novel construction whereby it can be readily applied to and removed from the rod, and in order that it will effectively carry out its function of supplying lllbllcant to the rod and cleaning oreign matter thereform, the device also being simple and inexpensive in construction as well as being efiicient and ractical in use.
With the oregoing and other objects in view, which will appear as the description proceeds, the invention resides in the comination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention can be made within the scope of what is claimed, without departing from the spirit of the invention.
The invention is illustrated in the accompanying drawing, wherein:
Figure 1 is a view of the swab, partly in elevation and artly in section.
Fig. 2 is a iametrical section on the line 2-2 of Fig. 1, one of the absorbent pads being removed.
Fig. 3 is a view of the device in 0 en position, one of the pads being remove The swab is of annular or ring like form to surround the piston rod, valve stem or other part termed hereinafter a rod, for convenience, and the device is divided on a diametrical line and comprises the complementar arcuate sections 1. Each of the sections 1 is composed of the arcuate side plates 2, the arcuate outer and inner walls 3 and 4, and the ends 5 providing a chamber 6 of ar- Speciflcatlon of Letters Patent.
Patented Mar. 12, 1918.
Serial No. 188,997.
cuate form in the section for containing grease, oil or other lubricant. The inner wall 4 and ends 5 of each section are s aced from the corrcspondin inner edges an ends of the side plates 2, whereby said edges and ends of the side plates provide flanges 7 defining pockets 8 therebetween extending along the ends and inner wall of the section from one end of the outer wall 3 to the other. The ends of the outer walls 3 of the two sections are provided with alinin hinge butts 9, and a hinge pin 10 is engage through one set of binge butts, to hingedly connect the sections 1, while a latch pin 11 is insertible through the other hinge butts to hold the sections in closed position when they surround the rod. By withdrawing the latch pin 11, the swab can be readily opened and closed in applyin or removing it.
Havin thus described the invention, what is claime as new is:
1. An annular swab to surround a reciprocating member comprising arcuate sections each having side plates, outer and inner walls and ends, the inner walls and ends being spaced from the inner edges and stripf of absorbent material doubled uponends of the side plates to provide ockets, inner walls havin apertures for t e, flow of lubricant into t e ets from said sections, means for hol g the sections together, and absorbent pads fitted in said pockets.
2. An annular swab tosurround a reciprocating member, comprising arcuate sections each having side plates, outer and inner walls and ends, and forming inclosed lubricant chambers, the inner walls and ends being spaced from the inner edges and ends .my own, I have hereto afiixed my a in the presence of two-witnesses.
