said U member is easily turned outwardly from the surface and that the recess remaining in the surface isvery slight. If the device be used for suspending a ceiling as suggested in Fig. 2, such deformation of the concrete surface is not material. In other character of surfaces where uniform appearance is desired, the slight depressions produced by the withdrawal of the U member may be filled with plastic material and usually in such other instances the surface of the concrete receives a final coat in which case the slight depressions would naturally be filled therewith and the concrete provide a uniform surface.
From the foregoing description it is believed evident that my improved insert for structures formed of concrete or plastic material is of very simple form; is inexpensive in construction consisting of two simply formed parts not requiring any careful machine work, and that in this simple and inexpensive form I have provided an insert that is well anchored in the body of concrete and upon removal of the form the projection part thereof is withdrawn to position for attachment of a member to be supported or joined to the concrete member, and further that the various objects and features of the invention are attained by the construction shown and described. Having thus fully described my invention, its utility and mode of operation, what I claim and desire to secure by Letters Patent of the United States is- 1. An insert for plastic material shaped by means of a form which consists of a body portion adapted to be embedded in the concrete at the time it is placed in the form, and a part consisting of a flat metal strip bent upon itself to form a U in pivotal relation with the body, and also embedded in the concrete by means of which it may be secured to an inner wall of the form whereby on removal of the form, the said part is pulled out of the plastic material to position permitting detachment from the form.
2. An insert for concrete or plastic material shaped by means of a form which consists of a body having an integral base adapted to support the same in a stable position on an inner wall of means of a form or mold consisting of a body formed with parallel foot portions and an intermediate loop like part extending into the body of the concrete and including a transverse portion extending to a plane slightly above the foot p01- tions, a member having spaced legs hinged to said transverse portion to lie on the same surface of the form supporting the foot portions and likewise embedded in the concrete, said legs having aligned apertures for receiving a nail in securing the insert to the inner wall of the form whereby, upon removal of the form, the said hinged element is forcibly withdrawn from its position in the concrete to a projecting position to receive an element to be supported.
4. An insert for concrete or like material shaped by means of a wood form which consists of a body formed of a metal rod like element having terminal foot portions bent to parallel relation and an intermediate connecting portion extending upwardly and thence downwardly terminating in a connecting transverse portion approximately centrally between the foot portions, a metal element hingedly secured to the transverse portion and embedded in the concrete, said hinged metal element being adapted to be secured to the surface of the form on which the foot portions rest andsimilarly embedded in the concrete whereby, after the concrete has been poured and set, the removal of the form draws the hinged metal element from the concrete to provide a projecting part adapted for attachment of a'tie member.
5. An insert for concrete or like material for use in the suspension of a member consisting of a body formed of a metal rod like element, the two end portions thereof lying in the same plane and the intermediate portion being upwardly and thence downwardly relative to each foot portion and connected by a transverse portion terminating in a plane just above the plane of the said 115 foot portions, a fiat strip of metal bent to provide a U engaging at a folded end over the said transverse portion, said metal strip having a part thereof extruded to prevent accidental removal of the U portion from said transverse portion, 120 the parts being so arranged that one leg of the U occupies approximatelythe same plane as the said foot portions, said legs of the U having aligned apertures for the reception of a nail or the like to secure the same to the portion of the 125 form or mold supporting the said foot portions whereby on removal of the form, the said U member is stripped from the concrete andturned to position to receive a member to be supported thereby, said member having an aperture for 130 alignment with the aperture of the said legs, and a bolt extending through the leg apertures and the apertures of the suspended element.
