Abstract
Abstract An apparatus for attaching a thermoplastic fitting to the side wall of a pipe is disclosed. The apparatus is made up of a generally U-shaped frame having legs supporting two spaced pipe clamps. The frame supports a fitting holder on a springloaded rod by which a controlled force can be applied on the fitting while fusing the fitting to the pipe. The fitting can also be moved toward and away from the pipe in order to insert and remove a heating mechanism to melt the plastic.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
345 words
A machine for attaching thermoplastic fittings to the sidewall of a thermoplastic pipe comprising: a generally U-shaped yoke having an intermediate member and two spaced legs intergrally attached to said intermediate member, a bearing member on said intermediate member between said spaced legs, a tubular member slidably received in said bearing member and disposed in parallel relation to said legs and axially slidably parallel to said legs, pipe clamping means on the distal end of each said leg romote from said intermediate member whereby a pipe for receiving a fitting may be supported on said legs in spaced parallel relation to said intermediate member, said clamping means comprising two first pipe clamp parts and two second pipe clamp parts, hinge means swingably connecting each said second pipe clamp part to a respective said first pipe clamp part and a clamping member on each said first pipe clamp part for clamping each said second pipe clamp part to a respective said first pipe clamp part with a pipe therebetween, means rigidly fixing each of said first pipe clamp parts to the distal end of each said leg of said frame, and means extending generally parallel to said intermediate member of said U-shaped yoke for rigidly supporting said second pipe clamp parts, a threaded rod telescopically received in said tubular member, means on said threaded rod for supporting a fitting support to be attached to said pipe, a longitudinally extending slot in said tubular member, and a compression spring in said tubular member engaging said threaded rod and adapted to urge said threaded rod toward a pipe supported in said pipe clamping means, a pin diametrically extending from at least one side of said threaded rod and received in said slot for limiting the movement of said threaded rod toward and away from said pipe, handle means attached to said frame and engaging said tubular member for moving said tubular member toward and away from said pipe, releasable means on said fitting support for holding a fitting to be attached to said pipe in said fitting support.
Claim 2
Dependent Claim
345 words
A machine for attaching thermoplastic fittings to the sidewall of a thermoplastic pipe comprising: a generally U-shaped yoke having an intermediate member and two spaced legs intergrally attached to said intermediate member, a bearing member on said intermediate member between said spaced legs, a tubular member slidably received in said bearing member and disposed in parallel relation to said legs and axially slidably parallel to said legs, pipe clamping means on the distal end of each said leg romote from said intermediate member whereby a pipe for receiving a fitting may be supported on said legs in spaced parallel relation to said intermediate member, said clamping means comprising two first pipe clamp parts and two second pipe clamp parts, hinge means swingably connecting each said second pipe clamp part to a respective said first pipe clamp part and a clamping member on each said first pipe clamp part for clamping each said second pipe clamp part to a respective said first pipe clamp part with a pipe therebetween, means rigidly fixing each of said first pipe clamp parts to the distal end of each said leg of said frame, and means extending generally parallel to said intermediate member of said U-shaped yoke for rigidly supporting said second pipe clamp parts, a threaded rod telescopically received in said tubular member, means on said threaded rod for supporting a fitting support to be attached to said pipe, a longitudinally extending slot in said tubular member, and a compression spring in said tubular member engaging said threaded rod and adapted to urge said threaded rod toward a pipe supported in said pipe clamping means, a pin diametrically extending from at least one side of said threaded rod and received in said slot for limiting the movement of said threaded rod toward and away from said pipe, handle means attached to said frame and engaging said tubular member for moving said tubular member toward and away from said pipe, releasable means on said fitting support for holding a fitting to be attached to said pipe in said fitting support.
Claim 3
Dependent Claim
48 words
The apparatus recited in claim 1 wherein said means for supporting said fitting support on said rod comprises, a threaded opening in one end of said fitting support and a threaded end on said rod whereby the distance of said fitting support from said spring can be adjusted.
Claim 4
Dependent Claim
25 words
The machine recited in claim 2 wherein a locking means is provided for locking said fitting support in a predetermined position on said threaded end.
Claim 5
Dependent Claim
14 words
The machine recited in claim 3 wherein said locking means comprises a set screw.
Claim 6
Dependent Claim
82 words
The apparatus recited in claim 1 wherein said fitting support is adapted to support a fitting above a heater supported on a pipe disposed in said clamping means and a heater locater comprising a threaded rod which is attached to one said leg of said U-shaped member, said heater locater being adapted to be adjusted toward and away from said fitting support whereby one side of said heater can engage said heater support thereby locating said heater relative to said fitting support.
Claim 7
Dependent Claim
54 words
The apparatus recited in claim 1 wherein said handle means comprises a handle swingably connected at an intermediate part thereof to said tubular member, a link swingably connected to said U-shaped yoke at a first end of said link, the second end of said link being swingably connected to one end of said handle.
Claim 8
Dependent Claim
66 words
The apparatus recited in claim 6 wherein a second link is swingably connected to said U-shaped yoke at a position spaced from said first mentioned link, said second link having a plurality of notches therein and a pintle in said handle at said intermediate part thereof, said second link notches being adapted to selectively engage said pintle whereby said handle is held in a predetermined position.
Claim 9
Dependent Claim
41 words
The machine recited in claim 1 wherein an elongated bar is fixed to said tubular sleeve adjacent the lower end of said tubular sleeve, whereby the ends of said bar slidably engage said legs, guiding said tubular sleeve up and down.
Claim 10
Dependent Claim
41 words
The machine recited in claim 8 wherein said bar is rectangular in cross-section and one of its major sides engage said tubular sleeve and the ends of said bar are twisted whereby a narrow edge of said bar engages said legs.
