@Application led April 9, 1913. Serial No. 759,834.
To alimen/limitait muy concernl Be it known that we, ARCHIET. MGAL- Lrsrnn and HARRY DrPPEL, citizens of the' -United tates,A residing. iny the city and county of .Philadelphia Jand State of Penn- Sylvania, have invented certain new and use- Yful Improvements in Hangers for Concrete Work, of which the following is a specification.
`Our invent-ion relates td hangers adapted to be embedded or molded in concrete workf be anchored(` on the usual metal rods .em-
ployed to reinforce the concrete and which will be provided with spaced or open parts between which the concrete may extend so' that the hanger will be roperly anchored, all as will be hereinafter ully described and particularly claimed.
Inv the accompanying drawings, illustrating our invention: Figure 1, is a plan of our improved hanger. Fig. 2, is a' vertical section thereof, on line 2-2 of Fig. 1. Fig. 3,
is a side view of the partls'of they hanger, slightly separated from each other. Fig. 4, is a vertical section through a portion of a mold filled with concrete, showing the hanger secured to the floor of the mold and embedded in the concrete therein.
Referring to the drawings, our hanger, in the preferred form of embodiment of our invention is -made\in three parts, a central body portion 3, a member or spider 4 above and laterally of the body portion 3 and a head 5 above the member 4. l. p
The body portion 3 is made in the form of a verticallyarranged block having upper and lower end aces 6 and 7 respectively, in parallel, horizontal planes and having an interiorly screw-threaded opening 8 extending vertically 'hito the lower end thereof and adapted to receive thc screw-threadedl like upper portion 9, having a hole 10 in the center thereof, and inclined arms 11 extending outwardly and downwardly from the portion 9 in spaced relation to each other and in spaced'relatio'i to the central hbody portion 3. The lower ends of the arms are provided with outwardly extending flanges l2 having holes 13 therein for the reception of nails or other devices to secure the arms tothe concrete mold, as will be hereinafter explained.
The head 5 comprises a lower, horizontalY portion 14, arms 15 extending upwardly and outwardly from the sides of th horizontal portion 14, a horizontally-arranged ring 16 vconnecting the upper ends of the arms 15 and a central, screw-threaded shank 17' 'extending downwardly from the portion 14.'
In assembling the three parts 4 and 5, i
the upper port-ion 9 of the vmember 4 is placed upon the upper `face 6 of the body portion 3 and the shan-lr 17 on the head 5 is passed through the opening 10 and screwed into an interiorly threaded hole in the upper end ot the body portion 3, thus clamping the member 4 firmly between thc body portion 3 and the head 5. When. the parts are thusassembled.y the bottom faces 18 of the arms 11 are in the same horizontal plane with the bottom face 7 of the block 3, and the axis of the opening S extends at right angles to this plane.
Our improved hanger is usually employed in the concrete forming the ceiling of a room, and, ,inl this connection, prior to. the formation of the ceiling, the hanger is placed upon the wooden board A19, as shown in Fig. 4, with the bottom faces 7 and 18` ot' the body portion 3 and arms 11 against the top of the board 19 or floor -of the mold. 'lhe lower ends of the arms 1 1 are then secured to the board 19 by driving nails 2O through the openingsl 13 and into the board 19, thus holding the hangerv in place with the axis of the opening 8 in true position at position at right angles to the bottom face of theconcrete or ceiling of the room.
When metal reinforcing rods are used in the concrete, the same may be placed to extend beneath parts of the arms 15 and ring 1G, as shown at. 22.511 Fig. 4t, and these rods 22 serve to more tlrmly anchor the hanger in the concrete.
By ,the construction of our hanger, the same may not only be firmly anchored in the concrete, but the parts serve to maintain the body portion 3 in trne position guarded by the arms l1 so that the raking and spreading of the concrete, the walking of workmen over the hanger and the rolling of wheelbarrows over the wet concrete and the hanger will not disturb theft-rue position of. the body portion 3.
`We claim: f 1. A. hanger for concrete work comprising a central body portion, a member engaged with the upper portion ot the body portion and having spaced arms extending downwardly therefrom, and means for securing said member to the body portion, said arms having` bottom faces in the same plane with a bottom tace of the body-'porJ tion, said faces being adapted to restnpon the door ci' a concrete mold, and the lower ends of said arms being adapt-ed to be secured to said door.
2. A hanger for concrete work comprising a central body portio'n, a member engaged with the top of the bo'dy portion and having spaced arms extending downwardly therefrom, anda head engaged with the top o't said member and having a screw-threaded shank extending through said member and screwed into said body portion, said arms having bottom faces in the same plane with a bottom face of the body portion, said faces beingadapted to rest upon the oor of a l concrete mold, and the lower ends of said l arms being adapted to be secured to said floor.
3. A hanger for concrete work comprising a lcentral body portion, a member engaged with the top of the body portion and having spaced arms extending downwardly there from, and a hcad engaged with the top ot saidvmember andv having a screw-threaded shank extending through said member and screwed into said body portion, said head being provided with upwardly and out 'ardly extending arms, the arms oit' said member having bottom faces in the same plane with av bottom face of the body portion, said faces being,` adapted ,to rest upon the. Hoor of a concrete mold, and the lower ends of said arms being adapted to be secured to said door.
Ll. A hanger for concrete work comprising a central body portion, a member engaged with the top of the body portion and having spaced arms extending downwardly there from, and a head engaged lwith the top oi said member and having a screw-threaded shank extending, through said member and screwed into said body portion, said head being provided with upwardly extending 'arms connected at their upper ends by a horizontally, arranged ring, the arms of said member having bottom faces in the same plane. with a bottom face ot the body portion, said faces being adapted to rest upon the iioor of a concrete mold, and the lower ends of said arms being adapted to be secured to said floor. In testimony whereof we alibi our signatures in the presence of two Witnesses.
