Multiple-bolt installation jig

Claim 5

The device claimed in claim 2 wherein said frame has a plurality of coupling holes therethrough and said coupling members are secured at one end in said coupling holes in said frame.

Claim 6

The device claimed in claim 3 further comprising releasable retaining means associated with said frame for releasably retaining said frame when said frame is mounted on said first body.

Claim 7

The device claimed in claim 4 wherein said retaining means includes a retaining pawl swivelably attached at one end to said frame and having a hook-shaped free end which releasably engages a pawl seat on said first body when said frame is mounted on said first body.

Claim 8

The device claimed in claim 4 further comprising moving means associated with said frame for moving said frame toward said flange and installing said coupling members into said aligned holes of said abutting body.

Claim 9

The device claimed in claim 6 wherein said moving means includes a spring attached at one end to a loop affixed to said frame and having a free end which releasably engages a looped nut attached to said flange when said frame is mounted on said first body.

Claim 10

The device claimed in claim 3 wherein said first body and said abutting body include flanged pipe sections, and said coupling members include bolts.

Claim 11

The device claimed in claim 3 wherein said first body includes a flanged beam.

Claim 12

The device claimed in claim 3 wherein said coupling members include rivets.

Claim 13

The device claimed in claim 3 wherein said first body further comprises at least one stop located thereon at a distance from said flange such that when said frame is mounted on said first body between said stop and said flange and is abutting said stop, the ends of said coupling members are seated in said holes in said flange.

Claim 14

The device claimed in claim 3 wherein said frame further comprises two additional holes disposed essentially diametrically opposite one another, said additional holes being larger than said coupling holes in said frame.

Claim 15

A multiple-bolt installation jig for simultaneously installing a plurality of bolts, whose ends are seated in coupling holes in a first flange of a first pipe, into aligned coupling holes in a second flange of an abutting pipe, and for simultaneously removing said plurality of bolts from said aligned coupling holes in said second flange, comprising: a frame movably mountable on a flanged first pipe and having bolts rigidly secured therein, said bolts extending longitudinally therefrom parallel to one another and being alignable with and seatable in said coupling holes in said first flange when said frame is mounted on said first pipe, said frame being movable along said first pipe in a direction parallel to the longitudinal axes of said bolts; and a retaining pawl swivelably attached at one end to said frame and having a hook-shaped free end which releasably engages a pawl seat on said first pipe when said frame is mounted on said first pipe.

Claim 16

A multiple-bolt installation jig for simultaneously installing a plurality of bolts, whose ends are seated in coupling holes in a first flange of a first pipe, into aligned coupling holes in a second flange of an abutting pipe, and for simultaneously removing said plurality of bolts from said aligned coupling holes in said second flange, comprising: a frame movably mountable on a flanged first pipe and having bolts rigidly secured therein, said bolts extending longitudinally therefrom parallel to one another and being alignable with and seatable in said coupling holes in said first flange when said frame is mounted on said first pipe, said frame being movable along said first pipe in a direction parallel to the longitudinal axes of said bolts; and a retaining pawl swivelably attached at one end to said frame and having a hook-shaped free end which releasably engages a pawl seat on said first pipe when said frame is mounted on said first pipe.

Claim 17

The jig claimed in claim 13 further comprising a spring attached at one end to a loop affixed to said frame and having a free end which releasably engages a looped nut attached to said first flange when said frame is mounted on said first pipe such that said frame is moved toward said first flange by the tension in said spring and said bolts are installed into said aligned holes of said second flange thereby upon release of said hook-shaped free end from said pawl seat.

Claim 18

The jig claimed in claim 14 wherein: said first pipe further comprises at least one stop located thereon at a distance from said first flange such that when said frame is mounted on said first pipe between said stop and said first flange and is abutting said stop, the ends of said bolts are seated in said holes in said firsT flange; and said frame further comprises two additional holes disposed essentially diametrically opposite one another, said additional holes being larger than said coupling holes in said frame.
