Abstract
Abstract An anchor bolt positioning apparatus which is to be used to mount an anchor bolt which is to be embedded within concrete. The apparatus utilizes an elongated planar plate upon which is centrally mounted a hollow sleeve. The threaded end of the anchor bolt is to be positioned within the hollow sleeve and extend outwardly therefrom with a nut to be threadably engaged with the threaded end of the anchor bolt and this nut then resting on the outer free edge of the sleeve. The inner end of the anchor bolt is to extend in the area defined by a pre-erected form for the concrete.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
217 words
An apparatus for positioning anchor bolts within concrete which is to be poured within a pre-erected form, composed of a pair of parallel spaced apart boards, said form comprising the space between said boards, said apparatus comprising: a mounting plate, said mounting plate being rigid and not penetratable, said mounting plate to be fixedly mounted on both said boards at a precise preselected position, said mounting plate having an upper surface and a lower surface, said lower surface to be located directly adjacent the concrete; an upstanding sleeve mounted on said upper surface of said mounting plate, said upper surface having a through opening, said through opening having a longitudinal center axis, said upstanding sleeve being of a preselected length, an anchor bolt is adapted to be located within said through opening with the outer portion of the anchor bolt to extend from said mounting plate and be embedded within the cement after pouring and curing of such; and said mounting plate including a series of holes with there being a series of said holes located directly adjacent each longitudinal end of said mounting plate, a said hole within said series of holes at each end of said mounting plate to have conducted therethrough a fastener with each said fastener then being embedded within a said form.
Claim 2
Independent Claim
