DEWEY H. BITNEY, ALBION, MICHIGAN, ASSIGNOR TO UNION STEEL PRODUCTS COMPANY, or ALBION, MICHIGAN ANCHOR INSERT FOR CONCRETE TVORK Application filed February 11, 1927. Serial No. 167,418.

The main object of this invention is to provide a concrete hanger insert for the supportv of ceilings and the like which is securely embedded within the concrete, may be easily adjusted or applied to the form, and one in which the lathing or supported element may be secured in a very effective manner and at such points as are best adapted to the element supported.

Objects pertaining to details and economies of my invention will definitely appear from the detailed description to follow. The invention is clearly defined and pointed out in theclaims.

A device embodying the features of my improvements is clearly illustrated in the ace companying drawing forming a part of this application, in which: 7

Fig. 1 is afragmentary sect1on through a concrete ceiling beam and form showing the relation of my improved concrete hanger insert in use.

Fig. 2 is, a fragmentary section with the form removed and with one of my improved hangers engaged with the insert.

Fig. 3 is a detail section corresponding to that of Fig. 2 with a fragment of expanded metal lath secured in position.

Fig. 4 is a fragmentary perspective of one of the inserts. r

Fig. 5 is a perspective view of one of the hangers.

Referring to the drawing, 1 represents a beam form and 2 the concrete beam or structure. My improved hanger comprises a channel insert 3 formed of sheet metal which is the desired length of the structure or formed in suitable lengths, as may be most desirable.

The insert 3 has downwardly converging side walls 4 one of which terminates in an inwardly and upwardly turned flange 5. This flange is spaced from the opposlte wall providing a space 6 for the passage of the hooks 7 of the hanger 8. The hanger is preferably a loop of wire, the hooks being disposed in the same direction so that they may both be engaged over the supportlng flange 5. r

9 represents the expanded metal lathing,

this being shown conventionally, and the hangers are passed about the part 10 of the lathing prior to engagement over the supporting flange 5. The end of the loop is then twisted as indicated at 11 until the lath is securely clamped against the beam, ceiling or other surface in which the insert is set.

By converging the walls of the insert downwardly the concrete has a very secure hold thereon. The insert is preferably provided with a series of holes 12 through the top or web thereof to receive the nails 13 by which the insert is temporarily secured to the form so that it is not displaced as the con- 3-65 crete is poured.

WVhen the form is removed it is pulled off these nails and the nails may be bent up into the channel if desirable.

My improved concrete hanger insert is sim- 370 ple and economical in structure, is capable of use in numerous relations, and the supported element may be very quickly and easily secured thereto.

Having thus described myinvention what I claim as new and desire to secure by Letters Patent is:

1. An anchor for concrete work comprising a channel member having forwardly converging side walls, one of said side walls having an inwardly and rearwardly turned flange at its edge, there being a space between said flange and the opposite side wall, which is without a flange, loop-like tie members provided with hooks engageable with said flange 3 55 through said space, said tie members being of bendable material whereby they may be twisted to clamp a supported element.

2. An vanchor for concrete work comprising a channel member having forwardly go converging side walls, one of said side walls having an inwardly and rearwardly turned flange at its edge, there being a space between said flange and the opposite side wall which is without a flange, and tie membersprovided with hooks engageable with said flange through said space.

3. An anchor for concrete work comprisring a channel member adapted to be embedded 1n a concrete body facing outwardly one of the side Walls having a continuous inwardly and rearwardly turned. flange, the 7 other being Without a flange, and tie members provided with hooks engageable with said flange.

In witness whereof I have hereunto set my hand. I
