1951 Concrete Cylinder Pipe Information 1

[CRWater]

Can anyone suggest a resource for specifications or details for 24-inch concrete cylinder pipe manufacutured about 1951 by LockJoint Pipe Co.? The installation is in Iowa, so presume this was a MidWest area company. Any knowledge of company history or successors?

I cannot supply any details of this pipe (other than hearing that it typically involved thicker cylinders and larger, lower strength wires for comparable sizes than some later versions, and that by that date however the Lock Joint pipe could conceivably have involved steel end ring/ o-ring "Carnegie joints", that I think were invented a few years prior to that). I think the Lock Joint Pipe Company merged with another company in the very early 1960's to become "International Pipe and Ceramics" or "Interpace". According to the Price Brothers Company at

http://www.pipesite.com/emergency.html,

"the Interpace Corporation, went out of the concrete pressure pipe business in 1986". Perhaps however they have some more details of the pipe? You could probably find much more information on history etc. with a google search.

[Oops, I am also aware that a paper was presented on the design of pipe at that time in the May 24, 1950 AWWA Annual Conference in Philadelphia, PA, and I guess a follow-up article was also published In the Nov. 1950 Journal AWWA by Mr. Hugh Kennison, at that time Chief Engineer of the Lock Joint Pipe Co. I saw that a sort of "Rubber and Steel Joint", that much resembles later versions, though it appeared in cross-sectional view with maybe some sort of extra, outer annular bell reinforcement outside the steel bell ring was in fact pictured in theat paper. I would assume you might still be able to get this paper from AWWA Publications.]
