HANGER-SOCKET FOR REINFORCED CONCRETE.

Specification of Letters Patent.

Patented June f, 1909,

Application filed January 21, 1909. serial No. 478,447.

Be it known that I, FRANK N. KNEAs, a residing in Norristown, county of Montgomery, State of Pennsylvania, have inventeda new and useful Hanger-Socket for Reinforced Concrete,

of which the following is a specification.

My invention relates to provision for attachment of'devices such as shafting'or other structures to cement or concrete beams.

The purpose of my inventionis to secure a socket rigidly against movement in any direction, to protect it from being filled by the concrete, and to sustain it by direct strain u on means engaging the concrete on A further purpose of'my invention is to provide a substantially U shaped support for a socket the anchorage being obtained by means of the sides of the U.

For the purpose of illustrating my invenshownfin the accompanying fornis thereof which are at een found in practice to give satisfactory although it is to be ties of which my invention consists can be variously arranged and organized and that my invention is not-limited to the precise arrangementand organization of these in scribed.

Figure 1 is a perspective of a structure embodying my invention. Fig. 2 is a transverse section of a structure similar to Fig. 1

Fig. 3 is a section the structure which I have shown in Figs.

' ,1 and 2 and taken upon line ac-ac, of Fig. 2.

Fig. 4 is a perspective of a modified form of my invention.

Similar numerals of reference indicate cor responding parts in the figures. I I

Referring to the drawings. My invention is intended particularly for use in connection with the manufacture of concrete beams and structures, whether reinforced forced, but most desirably 1n connection or not reinwith reinforced concrete, My anchor and socket are preferably rested upon the bottom board of the matrix or form within which the -beam or other concrete structure is being cast and are desirably temporarily attached to this-board for the purpose of prevent ng displacement of the during the casting art-s operation. Evident y the anchor can be so ably parallel du be supplied in place top of the beamor other concrete member. or to any surface .ofan inclined", or vertical member.

1 designates an anchor comprising preferplicate side pieces 2 and 3 and cross piece, bottom piece, 4 forming a substantially U- shaped structure preferably of flat or strip material. While the bounding surfaces of the flat standards 2 and 3 lend themselves to attachment to the concrete or cement, I preferably increase this attachment or anchorage by providing recesses e 5 and 6 of any suitab number which leave projecting fins or webs 7- and 8 of corresponding size and number engaging the concrete and retaining the anchor firmly in place.

garded in this case as the bottom portion, 4

of the yoke or U-s'haped anchor member 18 Y located as to present the socket at the side or for convenience regarded as The transverse, re-

apertured at 9 in line with the socket which is to be placed within it. This socket, 10, I have shown in the form of a plain square nut but any suitable means of attachment may of this, with whatever advantage the s ecific form of attachment desired may 0 er. The aperture of the socket, here bounded by thread 11, is in line withthe aperture 9.

In order't'o' provide a space above the nut or other socket, into which the belt or other corresponding member may project, and to protect against closure of the opening of the socket by the concrete or cement, 'I provide a cap 12 preferably comprising a top 13 and sides 14. I may provide this with lateral extensions 15, having. apertures 16 therein,

in order that the device may be conveniently and securely fastened to a board of the matriX or form.

It will be noted that I providespaced anchorageshaving laterally extending fins or webs for engagement with the concrete and retaining the socket between them. I These spaced-anchorages are preferably placed arallel with the reinforcing .rod's where t ese occur and do not-interfere with them.

The cap retains the socket against movement within the anchor and holds-the anchor in place against the board. The cap and the abutment of the bolt against the walls of the aperture-9 cooperate to keep the socket fixed against movement in all directions.

' In Fig. 4 I agreeing as to L. or other connectiondevice the socket and the cap in all particulars with the form shown in Figs. 1, 2 and 3, but having openings through the anchor for the passage of the transversely directed parts 17 and 18 of the upper part'19 of the anchor there used. This is preferably made in the form shown, with substantially, parallel vertical side bars 20, 21, 22 and 23, the bars 20 and 21 being united at the middle of the device by the cross bar 24 and the .bars 20 and22 and 21 and 23 being united respectively by the transverse members 17 and 18. The vertical bars 22 and 23 are shown as (erminatin in lateral extensions 25 and 26 which may e omitted if desired, these lateral extensions and the transverse portion 24 materially assisting in the anchorage of the The transverse members 17 and 18 here perform anadditional function by engagement with the surfaces 27, and 28, 29' and 30, respectively of the cap to retain the" cap in place against vertical and side movement-at all times even when the device/is not in use. The devices shown in Figs. 1, 2 and 3 are preferably made from pressed metal which is formed by cutting and bending dies to the desired Sl1LP6.' An ordinary square nut is inserted between the arms of the U and the cap, also preferably formed by dies alone, is inserted laterally and placed over the nut. When not in use the cap may be readily wired to the anchor, preventing displacement thereof.

.The device shown in Fig. 4 is assembled so far as .indicated the same as the devices shown in Figs. 1, 2 and 3 after which the wire anchor, at that time substantially in the shape ofa hair pin, is passed through the apertures in the sides 2' and 3 either before or after the bends at 31 and 32 have been made. Thearms 22 and 23 are'then bent to place and extensions 25 and 26 formed if deprovide the main anchorage.

sired.

It will be evident that the structures which I have illustrated may be constructed at a minimum of cost for labor and materials making use of such materials only as are readily available.

The structure of Fig. 2 differs from that of Fig. 1 in the apertures 33 only. These may be used with an anchor having notched edges, as shown, to increase the anchorage, or with an anchor having straight edges to In some of the smaller forms I omit the apertures and the notching, relying upon the adhesion to the sides alone. Either with or without the apertures or notchin I may also turn the upper ends of the U laterally either toward or awa from each other or one in each of these directions.

It will be evident that the exact structure need not be used to* obtain the main advantages of my device.
