Pipe size measuring tool

Abstract

A pipe size measuring tool having a plurality of gauges, each gauge having an open mouth there on. The sizes of the open mouths in each gauge are different from each other. The gauges are mounted together with each gauge having a front end, a body portion and a rear end. The gauges are pivotally mounted together adjacent their rear ends so that they are moveable from a folded compact position to an open postion. The front ends are wider than the rear ends and the gauges are thin and light-weight. Openings are provided in the rear ends so that the gauges may be pivotally mounted together at the rear ends. The gauges are of different sizes with the larger open mouths located in the larger gauges.

The embodiment of the invention is which an exclusive property or privilege is claimed as follows:  
     
         1 . A measuring tool comprising a plurality of gauges, at least some of the gauges having an open mouth, the sizes of the open mouth in at least some of the gauges being different from each other, said gauges being mounted together.  
     
     
         2 . A measuring tool as claimed in    claim 1    wherein each gauge has a front end portion, a body portion and a rear end portion.  
     
     
         3 . A measuring tool as claimed in    claim 2    in which the said gauges are pivotally mounted together adjacent their rear ends whereby the gauges are moveable from a folded compact position into an open position.  
     
     
         4 . A measuring tool as set forth in    claim 3    wherein the front end portions of the gauges are wider than the rear end portions.  
     
     
         5 . A measuring tool as set forth in    claim 4    wherein the front end portions and the rear end portions are connected together by tapered side edges.  
     
     
         6 . A measuring tool as set forth in    claim 5    wherein said gauges are thin and light-weight.  
     
     
         7 . A measuring tool as set forth in    claim 6    wherein openings are provided in the rear end whereby the gauges may be pivotally mounted together.  
     
     
         8 . A measuring tool as set forth in    claim 7    wherein the gauges are of different sizes with the large open mouth is in the larger gauge.  
     
     
         9 . A measuring tool as set forth in    claim 8    wherein the size of said open mouths are marked on said body portions.  
     
     
         10 . A measuring tool as set forth in    claim 9    wherein pipe thickness notches are provided at at least one of the edges of at least one of the said body portions.  
     
     
         11 . A measuring tool as set forth in    claim 10    wherein a plurality of notches are provided on the edges of said body portions, said notches being of different sizes.  
     
     
         12 . A measuring tool as set forth in    claim 11    wherein the size of said notches are marked on said body portions.  
     
     
         13 . A measuring tool as set forth in    claim 12    wherein said tool is provided with electronic read-out means whereby the correct size is displayed electronically on a display unit.  
     
     
         14 . A measuring tool comprising a plurality of gauges, each of said gauges having a body portion, pipe thickness notches being provided on at least one of the edges of a least some of the said body portions, said gauges being pivotally mounted together.  
     
     
         15 . A measuring tool as set forth in    claim 14    wherein a plurality of notches are provided on the edges of said body portions, said notches being of different sizes.  
     
     
         16 . A measuring tool as set forth in    claim 15   , wherein the size of said notches are marked in body portions.
