To all whom 'it may concern.

Be it known that I, JOHN EDWARD OGDEN,

a citizen of the United States of America, and a resident of Mountainville, town of Cornwall, Orange County, and State of New York, have invented certain new and useful Improvements in Concrete Inserts, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

This invention relates toV new and useful improvements in concrete inserts, and its object is to provide a simple and inexpensive device which may be easily embedded in concrete structures during their formation, which is adapted to receive the head or nut of a bolt, and to provide for adjustment of the position of the bolt.

These and other objects of the invention will appear in the following specilication in which I will describe the invention, the novel features o-f which wil-l be set forth in appended claims.

Referring to the drawings:

Figure 1 is a sectional elevation of a device of cast metal which is made .according to and embodies this invention. This is shown in the condition in which it comes from ythe casting mold.

Figure 2 is a similar section of the same device embedded in co-ncrete showing the positions which its parts assume when a bolt is being inserted.

Figure 3 is another sectional elevation of a device of a somewhat modified form embedded in concrete and with a member secured thereto by a bolt.

Figure 4 is a sectional plan view of the parts' shown in Figure 3.

Figure 5 is a sectional elevation of a device of still further modified form showing a bolt being inserted therein.

Like characters of reference designate cnrresponding parts in all the figures.

10 designates a body the inner wall of which is cylindrical. top, as shown at 11, and is partly closed at the bottom by an inwardly extending annul-ar flange 12 and has ears 13 and 14 pro'- jecting from it at spaced intervals. The ears 14 are preferably at the lower end of the body and constructed to form notches 15. 16 is a circular .disk provided with a slot 17. This disk is of greater diameter than the opening through the center of the flange 12 and of less diameter than that of This is closed at the,

1919. serial Nq. 308,687.

Lthe inside of the body 10.' In'makinglthe device the disk 16 is preferably put inside of the core 18 which determines the size and shape of the inside of the body. l

Before specifically describing the vstructures shown in the other figures of the drawings, I will point out the way in which this device is used. After the. body is cast the core 18 is broken up and removed. The disk, however, is too large to come out and therefore remains permanently inside of the body. When a concrete structure is to be made the device is placed on one of the form boards, and if desired, may be positioned thereon by tacks driven through the notches 1,5. The concrete is poured over and around the device as shown at 20 so that the insert becomes a permanent part of the finished structure.

A bolt 21 may now be inserted by pushing the disk upwardly as shown in Figure 2, until its head o-r a nut thereon passes the edge of the disk when the latter may fall down on to the fiange 12 with the shank of the bolt extending through the slot 17. This slot is narrower than the heador nut of the bolt so that the bolt will be held by the disk. 1

to amplify the range of adjustment of the bolt. l/Vhen a bolt is in the desired position, a member 22 may be secured by means of it and a nut 23. n

The ears 13 and 14 strengthen the-grasp of the concreteon the device. In Figures 3 and 4 the outer walls off the body 10A are transversely liuted or ribbed as shown in 24 to increase the grip ofthe concrete on the body.

The body 10B in Figure 5 `is open at the top. When this form is used it is not neces sary to cast the disk 16 in. the body as it may be inserted from the top, But in order to prevent` the concrete from entering the body, when it is poured, it is necessary to provide a. cover 25. Different modifications of structure may be made within the spirit and scope of this invention and I intend no limitations other than those imposed by appended claims.

l/Vhat I claim is:

1. The process of forming a concrete insert which comprises embedding 'a load carrying member within a `chamber for-ming core, casting the body of the insert-about to leave the loadVcarry-ng member eupported on the flange aforesaid.

2. The process of formlng a concrete 1nsertV Whlch vcornprlses, oa-stlng al` hollow 1n- V sert body about a load carrying element and with a flange to @Online the load ycarrying element Within the chamberof the lnshed 10 insert body. Y

n Witness whereof I hereunto set my hand this 27th day of June, 1919.
