WWVQ ATTORNEY Patented Mar. 8, i932 7 rnankjn HALDEN, or vrmnnarotrsnyxrnnnsorn ancnonafen mivrcn Application filed March 23', .1929. seriarnaa iaaiafl This invention relates to improvements in anchorages, particularly of the type intended for securing or bonding a facing to a structural member,,and-it consists, of the constructions, combinations, and arrangements hereln descrlbed and claimed. 1

An object of the invention is to provide simple and. thoroughly efficient device for securely bonding. or anchoring facing matew 10 'rial such as brick, tile, stone, terra cotta and the like to reinforcedconcrete columns or walls or other structural parts of buildings.

Another object of the invention is tojprovide an anchorage which is to be embedded in a plastic or other structural member, and

consists, essentially, of a slotted tubular.

structure into which the head of an anchor will be inserted upon presentation in one poanchorage shall run full length asjust stated.

sition then given a quarter-turn to assume the position that it will ultimately retain.

Other objects and advantages will appear.

in the following specification, reference being had to the accompanying drawings, in which: Figure ,1 is a cross section: of a portion of: a concretecolumn or other structural mem-' ber, illustrating the application of a number of the anchorages and'anchors used there i with, the bricks-that are bonded by 'the lat p rower than thecross sectional diameter ofiter being shown in plan,

Many plans have been devised and exeouted for securing an outer facing or veneer such as buck and the l ke, to an internal.

structural member such "as aconcrete or other column, but apparently the advantages of'a simple bonding device are yet to be realized for, although such devices Tare in 'use,yet in, many instances they are far from beingsim ple; either from the standpoint of actual I structure or installation, 4 Reference is made to the drawings. 'An

internalstructural member 1, whichin this instance is. regardedas a reinforced concrete column or-wall, has a number of bondingdevices 2 incorporated therein, these being herein identified as anchorages. Since. the con struction'of each bondingdevice is alike, the

description of one will suflicefor all, e The anchorage 2 in Figures 1, 2 and 8 comprises a tubular structure that is set vertically in the member 1 and defines a continuous,

vertical channel which may, if desired, run. full length of said member. It is a matter" of judgment with the mechanicv whether the chorage 2 define a slot:6 anddepressions 7 .j

The slot constitutes the entrance to the an-'rchorage, and as shown in Figure 2 is narthe tubular part. of' the anchorage The the'concrete isc-filled in the pouring of the} member 1, these fillings ultimatelydefining lugs which-contribute in 'a'large measure to retalning the anchorage in absolute .lmmovj ability;

The primary purpose of the flanges 8 is to p'rovideplaces where the anchorage can be secured "to-ithe form boards. Nails will be lightly driven through the flanges and into 1 Inwardly curled portions 15. vof the anthe boards fromthe inside of the forms The boards are later removedwithout difficulty and withoutdisturbingthe anchorage;

; A head 9 on the inner endof the anchor 3y i will occupy the position inithe anchorage 2 shown-in Figure 2;

is made by presenting it edge-on to thefslot 6 and giving it a quarter-turn so'thatit assumes The insertion of the head the position already mentioned. The outer end of the anchor terminates in a ring 10 or other configuration, the purpose of which is to increase the bonding effect when the mortar is spread over the anchor during the erection of the facing 4.

Figures l, 5 and G'illustrate a modification of the anchorage that is particularly adaptable as a pipe hanger. Those parts of this anchorage which are similar to the first form are identified by corresponding reference nu merals without necessarily repeating the specific description. It is observed that the modified anchorage has an upstanding fin 11. This fin is perforated at 12 so that the plastic material of the member 1 may enter and in crease the bond.

It is optional whether the fin 11 shall comprise a single member integral with a single tubular structure 2, or whether the latter shall be medially separated to compose halfsections and each section provided with a flange to compose the fin 11 when the sections are assembled as in Figure 4-. In either case the fin 11 and its perforations 12 will increase the carrying capacity of the anchorage, well adapting the latter to the purposes of a hanger.

The anchor 3, although similar to that shown in Figures 1 and 2, may be replaced by any device that will serve the purpose of a hanger. The anchorage 2 in Figures 4 and 5 will be cut off in relatively short lengths,

these being such as the mechanic may judge necessary to allow him space for adjusting the hanger to the right line. The head 9 of the hanger 3 is presented to the slot 6 as before, then given a quarter-turn so that it will remain locked in the pendant position.

End-closures 13 prevent filling the modified anchorage 9. with the plastic material of the ceiling or other structural member 1 and also prevent the collapse of the half-sections upon each other while assembling the tubular structure. These comprise cups 1 1- which are inserted in the ends of the anchorage. Each has a rim or flange 15 which extends beyond the sides of the cup thuscompletely closing the end of the anchorage. The flanges abut the edges ofthe tubular structure and limit the insertion of the end-closures. The flanges have extensions 16 that fit over the ends of the slot 6 for the purpose already stated. 7

It is understood that the end-closures 13 must remain in place when the modified anchorage is once installed in the member 1. The anchorage 2, while usually used in short lengths when serving as a pipe hangen will be provided long enough to aflord suiiicient latitude for the adjustment of the anchor 3. It will require but a brief reviewto emphasize themode of use of the bonding device in.

- Figures 1 and 2. The anchorages 2 will eX- tend vertically of the structural member 1',

and define slots or channels that will usually be continuous. As the outer facing 4 is erected, the anchors 3 will be inserted in the slots 6 and anchorages 2 in the manner already brought out, and imbedded in the mortar which is spread upon the various layers of bricks or the like. Some of the'mortar will be pressed into the anchorages to surround the heads 9 and thus increase the bond.

Whilethe construction and arrangement of theanchorage device herein described and claimed is that of, a generally preferred form, obviously modifications and changes may be made without departing from the spirit of the invention or the scope of the claims.

1. An anchorage comprising a tubular structure having anentrance slot, and endclosuresfor the ends of said'structure comprising cups'fitte'd into the tubular structure, and flanges on the cups to abut the edges of said structure to limit the insertion of the cups extending beyond the sides of the cups and including extensions covering the ends of the slot.

2. An anchorage comprising separably assembled half-sections having flanges, corresponding flanges having perforations and being abuttable to compose a fin and convert the half-sections into a tubular structure, and end closures fitting in said tubular structure to hold the perforations in matching relationship and to prevent relative sliding and the collapse of the half-sections upon each other. i I

3. An anchorage comprising a tubular structure having an entrance slot, 'end-closures for the ends'of said structure, comprising cups fitted into the tubular structure flanges on the cups extending beyond the sides of the cups to abut the edges of said structure to'limit the insertion of the cups and including extensions covering the ends of the slot, and an anchor having a heat insertible in the entrance slot and substan tially matching the inside cross sectional contour of thestructure'when in the suspended position. V y

4. An anchorage to be embedded in a sup port, said anchorage comprising a tubular structure which is substantially circular in cross section and having a slot narrower than the cross-sectional dimension, and an anchor having a head to occupy the tubular structure crosswise, and a shank extending from the head out of the slot, said shank being of lessthicknessthan the width of the slot to enable lateral. adjustments of the shank in the event of misalinement of the anchorage inits support, said head being substantially circular to enable turning when making said adjustments.
