UNITED STATES WILLIAM WHITE QF GHZIGAGD, ILLINOIS.

CONCRETE HANGER.

Application. filed May 3-,

To all whom it may concern.

Be it known that LIVILLIAM E. WHITE, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in a Concrete Hanger, of which the following is a specification.

My invention relates to hanger inserts and particularly to an improvement on the construction shown in my co-pending application Serial No. 556,597, filed April 26, 1922.

The improvements" herein claimed relate to the matter of simplicity and economy in the process of manufacture. One of the objects is to provide a hanger element adapted for vertical sliding movement within the housing, the hanger having the functions of a ring but which is so constructed as to avoid the necessity for a welding operation such as is required to produce a ring. Incidentally the construction contemplates the provision of hook members of such size and so located that the hanger element is nonrotatable within the housing and cannot become disengaged or misplaced in service.

Another object in my invention is to simplify the manner of construction and assembly of the housing employed.

The invention will be more readily understood by reference to the accompanying drawings, wherein,

Fig. 1 is a side elevation of a hanger constructed in accordance with my invention.

Fig. 2 is a view taken at right angles thereto;

Fig. 3 is a top plan view thereof;

Fig. 4 is a transverse sectional view, and,

Fig. 5 is a vertical sectional view.

In the drawings it will be seen that I provide a combined anchor and support con sisting of a length of wire rod bent to form a loop, consisting of parallel legs 10, and a horizontal connecting portion 1].. These parts, together with the laterally deflected portions 12, constitute the anchor of the device. The loop is contained within a housing which is formed by bending a flat strip of sheet metal into rectangular outline, as shown in Fig. 4, the marginal edge 13 being overlapped, as shown in Figs. 3 and 4. Continuous grooves 14 are formed .in the sides of the housing for the accommodation of parallel legs 10 of the anchor. The top is closed by utilizing the overlapping tongues 15, 16, respectively, integral with the side walls of the housing. The marginal edge 17 1922. Serial No. 558,134.

of the tongue 16 is bent downwardly, as shown in Fig. 5. In practice I have found it unnecessary to weld the overlapping parts as the housing is stable particularly after the concrete is poured therearound. The construction is such that the pressing of the plastic material on the exterior walls tends to firmly hold the casing in the desired relation of parts. As an additional means of retaining the casing in proper relation, I

provide the fastening staple, the legs 18 of which straddle the housing and frictionally engage the side walls thereof, as best shown in Fig. 3. This staple is described in my co-pending application heretofore referred to and serves the very useful purpose of retaining the hanger in position on a form prior to the pouring of the concrete.

The hanger element which constitutes one of the novel features of this invention, is

formed from a length of wire of substantial size and is bent to form a loop, as best shown in Fig. 2, the terminal portions 19, 20, being then-oppositely bent to provide hooks. The

spaces within the hooks are in line, and the" vision of the wide hooks 19, 20, results in a generally square outline, as best shown in Fig. 4, which while it fits within the housing renders the hanger incapable of rotation therein. Thus the hanger may be raised to the dotted line position of Fig. 1, as is necessary when the insert .is applied to a form, yet it obviates any possibility of failure to properly cooperate with the anchor loop when the hanger is dropped to its operative position. In other words, the hooks on the upper ends of the hanger cannot fail to engage the anchor nor can the hanger be disengaged or dislocated with out complete dismantling of the device The parts may therefore be, assembled as shown and shipped and handled without the possibility of any of the parts becoming disengaged or misplaced.

device is constructed on automatic machines and the manufacturing cost is thereby greatly reduced. 1

Obviously the construction is capable of much modification and I do not wish to be limited except as indicated in the appended claims.

I claim: g

1. In hanger insert, the combination of an anchor having a loop, a housing within which the loop is accommodated, said housing being of rectangular outline in cross section, and a hanger engaging said anchor loop and consisting of a length of wire doubled on itself and with. its ends bent to form oppositely projecting hooks, the lat ra l dimensions of the hooks being such that the hanger cannot rotate sufficiently wi hin the rectangular casing to permit disengagement of the hooks from the loop.

2. In a hanger insert, the combination of an anchor having a loop, a housing within which the loop is accommodated, and a hanger engaging said anchor loop and consisting of a length of wiredoubled on itself and with its ends bent to form spaced apart oppositely projecting hooks, the clearance between the walls of the housing and the lateral limits of the hanger being insufiicient to permit rotation of the hanger.

3. In a hanger insert, the combination of an anchor providing a depending loop, a

housing enclosing said loop, and a hanger consisting of a length of wire doubled into a loop and having hooks on its ends for engagement with said depending loop, the clearance between the walls of the housing and the lateral limits of the hanger being in suiiicient to permit rotation of the hanger.

4:. In a hanger, an anchor, a hanger element, and a housing providing a space within which the hanger may be received, said housing consisting of a sheet of material bent'into generally tubular form and provided with a pair of continuous longitudinal grooves in opposite side walls, and a pair of oppositely positioned integral lips for closing the otherwise open end of the thus formed housing.

5. In a hanger, an anchor including a depending loop, a housing providing grooves interiorly thereof for accommodating paral lel portions of the loop, an integral lip for closing the otherwise open upper end of the housing, and a swinging hanger mounted on. said depending loop.

6. In a hanger, the combination of an anchor having a depending loop, a housing provided with internal groove for accommodating the parallel portions of the loop, means for closing the upper end of the housing, a hanger element suspended from said loop, and a staple straddling said casing and serving to retain in place the means for closing the upper end of the casing.

Signed at Chicago, Illinois, this 28th day of April, 1922.
