Abstract
Abstract A pipefitter's jig for facilitating the coupling of a length of pipe to a pipe fitting comprises a base on which any one of a number of different blocks may be mounted, each block being recessed to conform to the configuration of the fitting and pipe to be coupled. Guide means is carried by the base for supporting a length of pipe in predetermined relation with reference to the pipe fitting and is movable toward and away from the fitting so as to adjust the relative positions of the fitting and the pipe.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
260 words
Apparatus for facilitating the coupling of a length of pipe in telescoping relation to a pipe fitting having at one end thereof an open mouth for the accommodation of a predetermined length of said pipe, said fitting having an internal shoulder spaced a predetermined distance inwardly from its open mouth and against which said length of pipe may seat, said apparatus comprising a base establishing a reference point; means carried by said base for supporting said fitting with said one end thereof fixed at a predetermined distance from said reference point; guide means for supporting said pipe in an initial position with one end thereof accommodated in said one end of said fitting and seated on said shoulder; means for fixing said pipe on said guide means when said pipe is in said initial position; means mounting said guide means on said base for free sliding movement in a direction away from said fitting supporting means whereby said one end of said pipe may be moved from said initial position outwardly of said fitting and out of engagement with said shoulder; and a stop member carried by said base at a second and greater predetermined distance from said reference point, said stop member being located in a path of movement of said guide means in said direction and being engageable by said guide means, said stop member being so positioned on said base that the maximum distance said guide means may move in said direction is less than the distance from said shoulder to said open mouth of said fitting.
Claim 2
Dependent Claim
260 words
Apparatus for facilitating the coupling of a length of pipe in telescoping relation to a pipe fitting having at one end thereof an open mouth for the accommodation of a predetermined length of said pipe, said fitting having an internal shoulder spaced a predetermined distance inwardly from its open mouth and against which said length of pipe may seat, said apparatus comprising a base establishing a reference point; means carried by said base for supporting said fitting with said one end thereof fixed at a predetermined distance from said reference point; guide means for supporting said pipe in an initial position with one end thereof accommodated in said one end of said fitting and seated on said shoulder; means for fixing said pipe on said guide means when said pipe is in said initial position; means mounting said guide means on said base for free sliding movement in a direction away from said fitting supporting means whereby said one end of said pipe may be moved from said initial position outwardly of said fitting and out of engagement with said shoulder; and a stop member carried by said base at a second and greater predetermined distance from said reference point, said stop member being located in a path of movement of said guide means in said direction and being engageable by said guide means, said stop member being so positioned on said base that the maximum distance said guide means may move in said direction is less than the distance from said shoulder to said open mouth of said fitting.
Claim 3
Dependent Claim
29 words
Apparatus according to claim 1 wherein said supporting means comprises a block mounted on said base, said block having a recess therein corresponding to the configuration of the fitting.
Claim 4
Dependent Claim
21 words
Apparatus according to claim 2 wherein said block also has a recess therein corresponding to the configuration of said pipe length.
