Abstract
Abstract A double tube mounting assembly as for securing a pair of hose tubes to a refrigerant compressor or the like having inlet and outlet openings therein to receive the free or pilot ends of the hose tubes. Each hose tube is provided with an annular upset bead adjacent to the pilot end of the tube which is sandwiched between a mounting plate, slotted at opposite ends to receive the tubes, and a centrally apertured yoke on each tube encircling the pilot end thereof, each yoke having spaced apart legs clamped around the side edges of the mounting plate. In the preferred embodiment, each yoke is welded or brazed to the annular bead of the tube with which it is associated to effect a fluid tight seal between these elements.

Claim 1
Independent Claim
330 words
A tube mounting assembly for securing N number of tubes to an accessory housing, the accessory housing having an N number of bored passages to receive the tubes, each of the tubes having an annular upset bead adjacent one end of the tube with a pilot tube portion extending outboard from one side thereof for insertion into one of the bored passages, a yoke for each tube, each yoke having a centrally apertured disc encircling said pilot tube portion on one of said tubes in abutment against the outboard side of said bead, an annular weld means around said bead securing and sealing said bead to said disc, an O-ring positioned to encircle the pilot tube portion of each tube in abutment against said disc of said yoke associated with said tube and, a mounting plate having an N number of tube receiving slot openings on opposite ends thereof with one of the N number of tubes positioned in each of said slots, said mounting plate further including an N number of opposed sets of locking slots on opposite sides thereof for each said slot aligned with the axis of one of said tubes positioned in said slot, said mounting plate being positioned on the opposite side of said bead in abutment thereagainst from said disc of said yoke associated therewith, each said yoke further including spaced apart legs extending axially from said disc for engagement with one of said sets of locking slots to lock said yoke and therefore said tube associated therewith against rotation relative to said mounting plate, each said leg including a leg portioN bent over to engage the opposite side of said mounting plate from said disc, said mounting plate having aperture means therethrough to receive fastener means for securing said mounting plate to the accessory housing with each said yoke and each said O-ring sandwiched therebetween with said O-ring in sealing engagement with said disc of said yoke associated therewith and the accessory housing.
Claim 2
Dependent Claim
330 words
A tube mounting assembly for securing N number of tubes to an accessory housing, the accessory housing having an N number of bored passages to receive the tubes, each of the tubes having an annular upset bead adjacent one end of the tube with a pilot tube portion extending outboard from one side thereof for insertion into one of the bored passages, a yoke for each tube, each yoke having a centrally apertured disc encircling said pilot tube portion on one of said tubes in abutment against the outboard side of said bead, an annular weld means around said bead securing and sealing said bead to said disc, an O-ring positioned to encircle the pilot tube portion of each tube in abutment against said disc of said yoke associated with said tube and, a mounting plate having an N number of tube receiving slot openings on opposite ends thereof with one of the N number of tubes positioned in each of said slots, said mounting plate further including an N number of opposed sets of locking slots on opposite sides thereof for each said slot aligned with the axis of one of said tubes positioned in said slot, said mounting plate being positioned on the opposite side of said bead in abutment thereagainst from said disc of said yoke associated therewith, each said yoke further including spaced apart legs extending axially from said disc for engagement with one of said sets of locking slots to lock said yoke and therefore said tube associated therewith against rotation relative to said mounting plate, each said leg including a leg portioN bent over to engage the opposite side of said mounting plate from said disc, said mounting plate having aperture means therethrough to receive fastener means for securing said mounting plate to the accessory housing with each said yoke and each said O-ring sandwiched therebetween with said O-ring in sealing engagement with said disc of said yoke associated therewith and the accessory housing.
Claim 3
Dependent Claim
48 words
A tube mounting assembly according to claim 1 wherein the N number of tubes is two and the N number of tube receiving slot openings in said mounting plate is two and, wherein said aperture means in said mounting plate is a central aperture through said mounting plate.
Claim 4
Dependent Claim
240 words
A dual tube mounting assembly including a pair of tubes to be secured to an accessory housing having a pair of spaced apart bored passages to receive said tubes and a fastener receiving means intermediate said passages, each said tube having a pilot tube portion at one end thereof for insertion into a bored passage in the accessory housing and an annular upset bead at the inboard end of said pilot tube portion, a flat mounting plate having a pair of slots, one on each end thereof to partly encircle one of said tubes and positioned so that the side of said bead opposite said pilot tube portion is in abutment against one surface of said mounting plate, said mounting plate further including side lock notches on opposite edge sides of each of said slots to provide a set of locking notches and a central aperture extending through said mounting plate to receive a fastener means for securing said mounting plate to the accessory housing, a pair of yoke means, each said yoke means encircling one of said tubes around said pilot tube portion thereof in abutment against the opposite side of said bead on said tube, said yoke means including leg means extending into engagement in one set of said locking notches with a portion thereof extending over the opposite surface of said locking plate whereby said bead is rigidly sandwiched between said mounting plate and said yoke means.
Claim 5
Dependent Claim
240 words
A dual tube mounting assembly including a pair of tubes to be secured to an accessory housing having a pair of spaced apart bored passages to receive said tubes and a fastener receiving means intermediate said passages, each said tube having a pilot tube portion at one end thereof for insertion into a bored passage in the accessory housing and an annular upset bead at the inboard end of said pilot tube portion, a flat mounting plate having a pair of slots, one on each end thereof to partly encircle one of said tubes and positioned so that the side of said bead opposite said pilot tube portion is in abutment against one surface of said mounting plate, said mounting plate further including side lock notches on opposite edge sides of each of said slots to provide a set of locking notches and a central aperture extending through said mounting plate to receive a fastener means for securing said mounting plate to the accessory housing, a pair of yoke means, each said yoke means encircling one of said tubes around said pilot tube portion thereof in abutment against the opposite side of said bead on said tube, said yoke means including leg means extending into engagement in one set of said locking notches with a portion thereof extending over the opposite surface of said locking plate whereby said bead is rigidly sandwiched between said mounting plate and said yoke means.
Claim 6
Dependent Claim
127 words
A dual tube mounting assembly according to claim 3 wherein each said yoke means includes a disc having a central aperture therethrough receiving said pilot tube portion of one of said tubes and wherein said leg means includes a pair of legs, one on each of opposite sides of said disc with each leg integral at one end with said disc and each leg extending axially inboard along said tube from said disc to engage into one of said locking slots, each said leg including a bent tab portion at the free end thereof engaging the opposite surface of said mounting plate from said bead and, said assembly further including an annular weld bead around said bead securing said bead to said disc of said yoke means.
