Abstract: Disclosed is a stanchion support device which comprises a washer having secured thereto a threaded column. About the threaded column is a toroidal collar of hard rubber. Placed over the threaded column is a metal sleeve. Threaded onto the threaded column is a nut which forces the metal sleeve downward against the rubber collar and pulls upwardly on the washer. The combined force of the sleeve and washer causes the rubber to expand. When this combination is placed within a cavity, such as may be defined by a cup placed in a cement floor, the rubber is so dimensioned as to engage the cup wall, thereby securing the stanchion support device within the cup. A stanchion may be secured to the nut. The stanchion itself may be provided with one or more L-shaped brackets which are freely rotatable thereupon and retained from sliding down the stanchion by a support, such as a ring, welded to the stanchion. An enlarged head of the stanchion prevents the removal of the bracket off the top of the stanchion.

Abstract: Disclosed is a device for forming apertures in cement or similar hardenable, plastic materials. The device, intended for use where holes of several inches in length are desired, comprises a body portion having affixed therein a threaded nut or coil. The body portion may be, for example, cylindrical in shape and be a solid elastomeric material having an aperture which extends axially through the body portion and communicates with a nut. The nut should be located adjacent the topmost portion of the body portion. A threaded rod may be inserted in the body aperture and screwed into the nut. A U-shaped bracket is provided which is placed on the hardened cement with the legs of the U-shape disposed on either side of body member. The joining member (which completes the U-shape) is spaced above and from the body portion by the legs. The joining member has a slot for receiving the bolt. The device is removed by threading a nut on the bolt down upon the joining member of the bracket.
