Claim 3

A rail according to claim 1 in which said opening is shaped inwardly of said top and bottom edges as an elongated rectangle having rounded internal corners.

Claim 4

A rail according to claim 1 in which said top and bottom are formed with shallow longitudinally extending grooves.

Claim 5

A rail for installation on a hospital wall or the like suitable for support of brackets and clamps for hospital apparatus, said rail having a back, a top, a bottom and a front, said front formed with a longitudinal inward extending opening having a top edge spaced down from said top, a bottom edge spaced up from said bottom, an upward extension inward of said top edge, a downward extension inward of said bottom edge and a back wall spaced forward of said back, said top edge being spaced below said top a greater distance than said bottom edge is spaced above said bottom, said top and bottom being formed with shallow longitudinally extending grooves, and a clamp, said clamp comprising a body shaped to fit across said front and having means for attachment of hospital apparatus to said clamp, a fixed first stud fixed to said body having a first bead on its distal end shaped to engage a first of said longitudinal grooves, said first stud being on one side of said rail, a rotatable second stud rotatable in said body, said second stud having a second bead on its distal end shaped to clamp said rail by engaging a second of said longitudinal grooves when said second stud is in first position and to be disengaged from said second longitudinal groove when said second stud is in second position, said second stud being on the side of said rail opposite said first stud and means on said body to move said second stud between position.

Claim 6

A rail for installation on a hospital wall or the like suitable for support of brackets and clamps for hospital apparatus, said rail having a back, a top, a bottom and a front, said front formed with a longitudinal inward extending opening having a top edge spaced down from said top, a bottom edge spaced up from said bottom, an upward extension inward of said top edge, a downward extension inward of said bottom edge and a back wall spaced forward of said back, said top edge being spaced below said top a greater distance than said bottom edge is spaced above said bottom, said top and bottom being formed with shallow longitudinally extending grooves, and a clamp, said clamp comprising a body shaped to fit across said front and having means for attachment of hospital apparatus to said clamp, a fixed first stud fixed to said body having a first bead on its distal end shaped to engage a first of said longitudinal grooves, said first stud being on one side of said rail, a rotatable second stud rotatable in said body, said second stud having a second bead on its distal end shaped to clamp said rail by engaging a second of said longitudinal grooves when said second stud is in first position and to be disengaged from said second longitudinal groove when said second stud is in second position, said second stud being on the side of said rail opposite said first stud and means on said body to move said second stud between position.

Claim 7

A combination of claim 4 in which said second bead is formed with a flat so that when said second bead is in second position said flat said rail.

Claim 8

A combination of claim 4 in which said second stud is rotatable to a third position intermediate said first and second position to cause said second bead to fit partially into said second longitudinal grooves to permit said clamp to slide longitudinally of said rail without disengagement from said rail.

Claim 9

The combination of claim 4 in which said last named means comprises a knob fixed for rotation with said second stud.

Claim 10

The combination of claim 7 which further comprises a spring-biased detent in said knob and plural depressions in said body engageable with said detent to locate said second stud in either of said positions.

Claim 11

The combination of claim 8 in which said knob is of cylindrical shape but a portion of said cylindrical shape is truncated.

Claim 12

A clamp for use with a rail having a front and top and bottom faces, one said face having a first shallow longitudinal groove spaced rearward of said front and the other said face having a second shallow longitudinal groove spaced rearward on said front, said clamp comprising a body shaped to fit over said front transversely of said rail, a first stud projecting rearward of said body on one side of said rail having a first bead shaped to partially fit into said first groove, a second stud projecting rearward of said body on the side of said rail opposite said first stud, said second stud being movable relative to said body between first and second positions, said second stud having a second bead shaped to clamp said second groove when said second stud is in first position to restrain longitudinal movement of said clamp relative to said rail and to disengage from said second groove when said second stud is in second position, and adjustment means on said body to move said second stud between positions.

Claim 13

A clamp for use with a rail having a front and top and bottom faces, one said face having a first shallow longitudinal groove spaced rearward of said front and the other said face having a second shallow longitudinal groove spaced rearward on said front, said clamp comprising a body shaped to fit over said front transversely of said rail, a first stud projecting rearward of said body on one side of said rail having a first bead shaped to partially fit into said first groove, a second stud projecting rearward of said body on the side of said rail opposite said first stud, said second stud being movable relative to said body between first and second positions, said second stud having a second bead shaped to clamp said second groove when said second stud is in first position to restrain longitudinal movement of said clamp relative to said rail and to disengage from said second groove when said second stud is in second position, and adjustment means on said body to move said second stud between positions.

Claim 14

A clamp according to claim 10 in which said second bead is generally circular but formed with a flat, said flat being parallel to said rail when said second stud is in second position to permit removal of said clamp from a rail.

Claim 15

A clamp according to claim 10 in which said second stud is movable to a third position intermediate said first and second positions, said flat being at an angle to said rail when said second stud is in third position to permit sliding of said clamp along ,said rail without disengagement of said clamp from said rail.

Claim 16

A clamp according to claim 10 in which said second stud is rotatable in said body and said adjustment means is a knob fixed for rotation with said second stud.

Claim 17

A clamp according to claim 13, in which said knob is formed with a bore facing said body and which further comprises a detent and a spring in said bore biasing said detent toward said body.

Claim 18

A clamp according to claim 14 in which said body is formed with a plurality of depressions in which said detent engages to locate said second stud in one of said positions.

Claim 19

A clamp according to claim 15 in which said knob is generally cylindrical and has an outer end truncated by a second flat.
