Abstract
Abstract A concrete insert device utilizes a longitudinal tubular member disposed about a given axis. A bolt member of a length less than the height of the tubular member is secured within the tubular member by coupling means. The coupling means permit positioning of the bolt in said tubular member along any axis intersecting an open face area bounded by the top periphery of the tubular member, which axes are parallel to the given axis. The coupling means further assures that the threaded portion of the bolt as desirably positioned, also extends about the height of the tubular member; to which threaded portion a machine member to be mounted on a concrete floor is thus secured.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
155 words
A concrete insert apparatus comprising, a. a longitudinal tubular member disposed about a given axis and having an open face end, b. a bolt member having a threaded end and a head end, and of a predetermined length, c. an extendable member coupling said head end of said bolt member to said longitudinal tubular member within said tubular member, said extendable member being of a length to permit said threaded end of said bolt to move substantially out of said open face while further permitting said bolt to assume any one of a plurality of positions occupied by the plurality of axes parallel to said given axis and contained within the boundaries of said open face end. d. a grouting material disposed within the internal cavity of said tubular member for rigidly securing said extendable member within said tubular member while rigidly maintaining said bolt member in a desired one of said plurality of positions.
Claim 2
Dependent Claim
155 words
A concrete insert apparatus comprising, a. a longitudinal tubular member disposed about a given axis and having an open face end, b. a bolt member having a threaded end and a head end, and of a predetermined length, c. an extendable member coupling said head end of said bolt member to said longitudinal tubular member within said tubular member, said extendable member being of a length to permit said threaded end of said bolt to move substantially out of said open face while further permitting said bolt to assume any one of a plurality of positions occupied by the plurality of axes parallel to said given axis and contained within the boundaries of said open face end. d. a grouting material disposed within the internal cavity of said tubular member for rigidly securing said extendable member within said tubular member while rigidly maintaining said bolt member in a desired one of said plurality of positions.
Claim 3
Dependent Claim
85 words
The concrete insert apparatus according to claim 2 further comprising, a. a second tubular member of a smaller diameter than said first and having open top and bottom ends, said bottom end coacting with the internal cavity of said tubular member and said top end being positioned in the same plane as said top open face of said longitudinal member, said tubular member serving as a grout passageway to permit grout to be introduced within said cavity when said top open face is undesirably blocked.
Claim 4
Dependent Claim
25 words
The concrete insert apparatus according to claim 1, wherein said bolt member comprises An eyebolt having an eye head end encircled by said extendable member.
Claim 5
Dependent Claim
41 words
The concrete insert apparatus according to claim 3 wherein said extendable member comprises a chain including a first and a last link, said last link encircling said eye of said bolt member and said first link coupled to said tubular member.
Claim 6
Dependent Claim
37 words
The concrete insert apparatus according to claim 3 wherein said extendable member comprises a coiled steel cable, having one end fixedly encircling said eye of said bolt member and said other end coupled to said tubular member.
