Abstract
Abstract A device for supporting in selected alignment pipelike elements, such as sectional sewer pipes and drain tiles, in an excavation during the positioning of the pipe therein and prior to the filling in of the excavation with particle material. The device consists of an upright two-legged frame and movable pipe-supporting slides that provide for easy removal of the device from the excavation after it has supported and maintained the alignment of the pipelike elements during the pipe-laying operation.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
128 words
A pipe-supporting device adapted to be temporarily used during the laying and alignment of pipe sections in an excavation or the like, comprising (a) a pipe-supporting frame having a crossbar connected at opposite ends at right angles to a pair of depending posts, (b) a strengthening bracket within said frame having oppositely disposed struts extending angularly between said crossbar and each of said posts, (c) a pair of pipe-supporting members carried by said frame and said strengthening bracket and movable through intersecting paths relative to each other and a pipe section supported beneath said frame, (d) and means on said frame and said strengthening bracket through which said pipe-supporting members are free to move through intersecting paths relative to each other at a point beneath said strengthening bracket.
Claim 2
Dependent Claim
128 words
A pipe-supporting device adapted to be temporarily used during the laying and alignment of pipe sections in an excavation or the like, comprising (a) a pipe-supporting frame having a crossbar connected at opposite ends at right angles to a pair of depending posts, (b) a strengthening bracket within said frame having oppositely disposed struts extending angularly between said crossbar and each of said posts, (c) a pair of pipe-supporting members carried by said frame and said strengthening bracket and movable through intersecting paths relative to each other and a pipe section supported beneath said frame, (d) and means on said frame and said strengthening bracket through which said pipe-supporting members are free to move through intersecting paths relative to each other at a point beneath said strengthening bracket.
Claim 3
Dependent Claim
55 words
A pipe-supporting device as defined in claim 1, wherein said pipe-supporting members comprise a pair of elongated slides carried by said frame and said strengthening bracket and adapted to be moved perpendicularly to said struts with their free confronting ends intersecting beneath the wall of a pipe section adapted to be supported by said frame.
Claim 4
Dependent Claim
71 words
A pipe-supporting device as defined in claim 2 including a plurality of spaced apart sleeves carried by said crossbar and said posts and other corresponding coaxially aligned sleeves carried by said struts of said strengthening bracket, with said pipe-supporting slides adapted to be freely journalled through any set of coaxially aligned sleeves so as to have their free ends intersect beneath the wall of a pipe section having a predetermined diameter.
Claim 5
Dependent Claim
32 words
A pipe-supporting device as defined in claim 1, wherein said means on said frame and said strengthening bracket comprise spaced apart coaxially aligned sleeves through which said pipe-supporting members are freely journalled.
Claim 6
Dependent Claim
71 words
A pipe-supporting device as defined in claim 4, including a plurality of spaced apart sleeves carried by said crossbar and said posts and other corresponding coaxially aligned sleeves carried by said struts of said strengthening bracket, with said pipe-supporting members adapted to be freely journalled through any set of coaxially aligned sleeves so as to have their free ends intersect beneath the wall of a pipe section having a predetermined diameter.
