This invention relates to improvements in pumps.
The main objects of this invention are:
First, to provide a packing for the pump rods of oil well and likeI pumps Vwhich is capable of withstanding the severe working conditions yto which such pumps are subjected in use, at the same time allow'a freer movement kof thev pump rod packing plunger or the packed portion of the pump "rod whereby the wear is kreduced -to a minimum.
Second, to provide a resilient supporting connection between the pump rod packing cylinder and the casing which permits the adjustment of the reciprocating parts to each other and thereby minimizes friction and wear,
Third, to provide a structure in which a plurality of packing rings are spacedthroughout the length of the packing plunger thereby providing a long bearing with sufiicient clearance `between the plunger and the cylinder to minimize friction and'at the same-time provide an efficient seal. 1 i
Fourth, to provider4 a structure vhaving these advantages which may be adapted to standard l or widely used types of pumps.
Objects relatingto details and economiesv of the invention will appear from-the'de'scription to follow. The invention is dene'd'in'the'claims. A preferred embodiment of the invention is illustrated in the accompanying drawing, in
which:
Fig. 1 is a'fragmentary side elevation partially "in longitudinal section of a structure embodying my invention as applied to an oil well pump.
Fig. 2 is an enlarged fragmentary vie'wmainly in longitudinal section 'illustrating the details ofthe mounting of the packing' cylinder 4in its relation to the pump casing. Y Fig. 3 is a fragmentary View partially in 'longitudinal section of Ya `mcniiied form or embodilmentofmyinventon. y N
InA the embodiment the tubular pump casing ori the upperV end of I the pipe of a well and@ Vthe Aplur'iger rod. '3L-is T- fitting threaded'on theend of the casing andinas an oil outlet pipe 4 connected thereto.l Threaded linto the outer vend of this coupling-'is'lan adapter 5 having an internal bore is' and'externallvl threaded at `1 to receive the' vclamping sleeve or cap 8. The sleeve 8 hasan inturned flange 9 at its Aupper end. The pum'p rod packing cylinder projects into the casing I a substantial distance andalso projects from the casing.
The pump rod packing cylinder 'I I reciprocatcs fwithinithis cylinderIU. y
Theycylinder I0 is provided with an annular flange from but iixedly secured thereto as by Welding as indicated at I3. This supporting member is sunicient depth case, an annularthrus'thmember I8 disposed between the rubber orl other resilient supporting elements- I4, the inner of which is .seatedon the end offthe adapter 5 and the outer of which isbetweenthe iiange 9 and the supporting flange I2 on the cylinder.
, .The diameter of the cylinderrelative to the internal diameter-of the casingl I, vthe adapter 5, and thefiange v9 of the `clamping collar is such ,asL to permit a substantial vtilting movement of the .cylinderwhichrispermitted by its resilient supporting elements. These supporting members also constitute .packing members.

In' structures embodying my invention, it is not necessary to replace the packings frequently asvisvnecessary in the widely used type of oil I attribute the Awear on the packing in these v,pumps quite largely to the swaying of the pump rod vduring vthe'reciprocal-.ing movement tliereof. yThis results"inV wearing the packing vvd randsoon necessitates the re-packor' results" 'in' the leaking'of oil which is not out, 0f ine Yonly]'vl/"aste'f'ulbutr constitutes serious re hazard.
