4 Claims. (Cl. 72- 105) steel is placed, with the result that many of them.

are misplacedduring the setting of the steel. Such devices are frequently located in narrow or otherwise constricted spaces and this, as well as considerations of economy, make it necessary that the entire device, including-the flange, be relatively narrow. It'is frequently desirable that the devices be positioned exactly perpendicular to or at some definite selected inclination to the face of the Wall or beam in which the devices are embedded. The fastening of an elongated unitary device to a form by driving nails through anend flange is obviously difiicult and is also time consuming. In many instances, a. plurality of'such devices are provided-as a support for a single apparatus thereby making it necessary that the devices be accurately spaced and aligned. The location of the devices is indicated by marking the form in any suitable manner and exact spacing of the device requires that the individual devices be exactly positioned over the marks indicating their location. Obviously, the exact centering of an elongated unitary device over such a mark is also difficult and time consuming, particularly with devices not having a'continuous longitudinal bore.

The above described difficulties inherent in exactly locating unitary inserts on forms of concrete or'similar structures are eliminated by providing an insert device consisting of a centrally aperturedflange member adapted to be exactly positioned and securely fastened to the form before reinforcing steel is set, and a hollow elongated stem or body member adapted to be atbe quickly and easily fastened to the form and offers no obstacles to the placing of the reinforcement. The flange is preferably constructed of non-corrosive metal and the stem or body portion may be constructed ,of steel or other, mate rial providing the requisite strength and of relatively small diameter or lateral dimensions such that it does not interfere with the placing of the reinforcing steel.

It is 'an object of the invention to provide insert devices as an assembly of two members of the kind described whereby such devices are adapted to be located with exactness and facility. in any selected position on a form and may be quickly and easily fastened to the form by the use of any ordinary tool such as a hammer. 1

Another object of the invention is the provision of improved insert devices of the kind described which are adapted to be mounted on-a form without interfering with the placing of reinforcing material.

A further object of the invention is the provision of a device of the kind described which is inexpensive to manufacture, durable, simple'in construction and satisfactory for its intended.

purpose. V a V Many other objects and advantages of the construction herein shown and described willbe obvious to those skilled in the art from the description herein given.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described and more particularly pointed out in the claims.

Referring to the drawing, wherein like reference characters indicate like or corresponding parts: I

Fig. 1 is a sectional View of a fragmentary portion of areinforced concrete beam or ceiling Wall showing the'assembled device as embedded in the concrete and fastened to a form;

Fig. 2 is a longitudinal sectional View showing:

the device as comprising a main body portion and f lar nailing flange l2 providing a plurality of ,holes l3 arranged in circumferentially spaced-apart relation through which nails M are adapted to v be driven to fasten the member to aform I5 before mounting the bar [0 thereon.

The member H has accentral aperture I 6, preferably frusto-conical, and is thereby adapted to receive the adjacent end of the rod II] which is tapered to closely fit therein. The member II a may be exactly located in any predetermined positionon the form indicated by a suitable mark or otherwise since the mark. can be observed 1 through the aperture Hi. In the eventthemember II happens to be centered over the contiguous edges of adjacent boards comprising the form I5,

the member may be shifted circumferentially so.

that all of the holes i3 are spaced apart from th contiguous edges of the form boards. a

The thickness of the flange l2 'is such that it:

does not interfere with overlying reinforcement and the depth of the member ll is'such thatit can be nailed or; otherwise fastened to the'iorm' l5 with facility. The rod l0 isgfirmly. anchored in the concrete by providing it with a head I! which may be'formed integrally with the rod but is shown in the drawing as comprising a stand-' A close binding fit of ,the rod 10 in the aperture .16 issecured by merely striking the head I! or the ad-, jacent end of the rod'with a hammer after the am nut since the latter is'less expensive.

member I I is nailed to the form.

' The rod "I0 is provided with a threaded axial bore I8 open at the tapered end of the rodfor the reception of bolts, rods or any member :forming a connection andfsupport-for apparatus to be suspended from or supported by the concrete structure upon removal of the form l5. s The ex posed face of themember, i] coincides with the surface of the wall and upon removal of the forms quickly and easily mounted on the flanged meme her in exact perpendicularity or atjany other req-' uisite angle to the" surface of the structure bounded by the form after reinforcementis placed therein.

Having thus described my invention, 'it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement, and combination of parts herein shown and described or uses mentioned. 7

What I claim as new and desire to' secure by Letters Patent is: V V

1. An insert device of the kind described for concrete and similar structures comprising an assembly of two cooperating members, one of said "members being shallow and providing meansfor fastening it to a form prior to assembly,-the other 1;

of said'members being elongated and having a threaded bore open at one end, said shallow mem-- ber having a central aperture convergent toward the form and said elongat'edfmember having its open end bounded by a tapered surface adapted to closely fit insaid aperture when the members are assembledi 2.- An insert device of the kind described com:

prising a pair-of members adapted to be assembled in cooperative relation, one of said members being 7 elongated and having a threaded bore open at,

one end and the other of said members being shallow and providing means adapting it to be f astended to a form and providing a central aperture," one of the said membersproviding an outer bounding surface convergent towards the other, said other of the said members providing an inner bounding surface similarly convergent toward the other member to provide a close fitting Seat for said convergent bounding surface when'the members areassembled with said bores and aper-.,

tures in axial alignment.
