Crimping Machine

Claim 2

Apparatus for crimping a fitting onto an elongated member, comprising: ram means with a longitudinally movable piston having forward and rearward ends, said piston having a central passageway; a plurality of crimping dies movable radially together and apart, said piston having a camming surface at its forward portion for engaging said dies to move them radially together when the piston moves longitudinally; a mount coupled to said ram means, said mount fixing the position of said ram means with the central passageway of the piston extending horizontally; said central passageway extending along the entire length of the piston to receive said elongated member in extention therealong, and said ram means being devoid of obstructions behind the center of said passageway, whereby the elongated member can project completely through the rear of the apparatus.

Claim 3

A crimping machine comprising: a hydraulic cylinder having concentric inner and outer tubular walls forming an annular region therebetween, said inner tubular wall having a forwardly extending portion with a plurality of radially-extending guideways; a plurality of crimping dies radially moveable in said guideways of said inner tubular member; and a piston of tubular shape with a rearward portion disposed in said annular region of said hydraulic cylinder between said tubular walls thereof, and having a forward portion forming a camming surface engaged with said crimping dies to move them radially along the guideways in said inner tubular wall.

Claim 4

A crimping machine comprising: a hydraulic cylinder having concentric inner and outer tubular walls forming an annular region therebetween, said inner tubular wall having a forwardly extending portion with a plurality of radially-extending guideways; a plurality of crimping dies radially moveable in said guideways of said inner tubular member; and a piston of tubular shape with a rearward portion disposed in said annular region of said hydraulic cylinder between said tubular walls thereof, and having a forward portion forming a camming surface engaged with said crimping dies to move them radially along the guideways in said inner tubular wall.

Claim 5

Apparatus for crimping a fitting onto a long hose-like member, comprising: a ram having an annular hydraulic cylinder with a hole through the center, and having a longitudinally moveable piston of annular shape to move in said cylinder; a plurality of crimping dies moveable radially together and apart, said piston having a camming surface engaging said dies to move them radially together when the piston moves longitudinally; said piston having a central passageway extending along its entire length to receive said long hose-like member in extension therealong, whereby the hose-like member can project through the ram portion that moves the piston and through the piston so that the end of the fitting opposite the crimped portion can project from the machine.

Claim 6

Apparatus for crimping a fitting onto a long hose-like member, comprising: a ram having an annular hydraulic cylinder with a hole through the center, and having a longitudinally moveable piston of annular shape to move in said cylinder; a plurality of crimping dies moveable radially together and apart, said piston having a camming surface engaging said dies to move them radially together when the piston moves longitudinally; said piston having a central passageway extending along its entire length to receive said long hose-like member in extension therealong, whereby the hose-like member can project through the ram portion that moves the piston and through the piston so that the end of the fitting opposite the crimped portion can project from the machine.

Claim 7

Apparatus for crimping a fitting onto a long hose-like member, comprising: a ram with a longitudinally moveable piston; a plurality of crimping dies moveable radially together and apart, said piston having a camming surface engaging said dies to move them radially together when the piston moves longitudinally; said piston having a central passageway extending along its entire length to receive said long hose-like member in extension therealong, so that the hose-like member can project through the piston to allow the end of the fitting opposite the crimped portion to project from the machine; a front member having radial guideways for guiding the crimping dies against a fitting; and means for holding the front member spaced in front of the ram; said front member having a groove extending in a primarily radial direction along the front surface therEof, from the radially innermost part thereof, to receive a portion of a gooseneck fitting.

Claim 8

Apparatus for crimping a fitting onto a long hose-like member, comprising: a ram with a longitudinally moveable piston; a plurality of crimping dies moveable radially together and apart, said piston having a camming surface engaging said dies to move them radially together when the piston moves longitudinally; said piston having a central passageway extending along its entire length to receive said long hose-like member in extension therealong, so that the hose-like member can project through the piston to allow the end of the fitting opposite the crimped portion to project from the machine; a front member having radial guideways for guiding the crimping dies against a fitting; and means for holding the front member spaced in front of the ram; said front member having a groove extending in a primarily radial direction along the front surface therEof, from the radially innermost part thereof, to receive a portion of a gooseneck fitting.

Claim 9

Apparatus for crimping a fitting onto a long hose-like member, comprising: a ram with a longitudinally moveable piston; and a plurality of crimping dies moveable radially together and apart, said piston having a camming surface engaging said dies to move them radially together when the piston moves longitudinally; said piston having a central passageway extending along its entire length to receive said long hose-like member in extension therealong, whereby the hose can project through the piston so the end of the fitting opposite the crimped portion can project from the machine; said ram including an inner tubular member with a rearward portion disposed within said piston to guide it in axial movement, said inner tubular member having a forwardly-extending portion with a plurality of radially extending guideways for guiding said crimping dies in radial movement.

Claim 10

Apparatus for crimping a fitting onto a long hose-like member, comprising: a ram with a longitudinally moveable piston; and a plurality of crimping dies moveable radially together and apart, said piston having a camming surface engaging said dies to move them radially together when the piston moves longitudinally; said piston having a central passageway extending along its entire length to receive said long hose-like member in extension therealong, whereby the hose can project through the piston so the end of the fitting opposite the crimped portion can project from the machine; said ram including an inner tubular member with a rearward portion disposed within said piston to guide it in axial movement, said inner tubular member having a forwardly-extending portion with a plurality of radially extending guideways for guiding said crimping dies in radial movement.
