April 29, 1930. G. B. BOSCO Filed May 2, 1928 @gfw Patented Apr. 29, 1934;) I V GEORGE IB. BOSGO, oracnreaco,;i i.ii iois Application filed May .2, 1:528. ste m; 12am- The main objects of this invention are to provide an improved form of anchoring device for tying a member to a structural unit to provide an improved anchoring device 5 which is particularly adapted for use as a wall tie or as a concrete insert used in con crete construction Work; to provide a device of this kind having an improved form of channel member adapted to be embedded in a concrete unit; and to provide an anchoring device having an improved form of tie adapted to be bent to various angular positions rel-7' ative to the channel for attachment to different kinds of structural facing units.
1'5 Illustrative embodiments of this invention are shown in the accompanying drawing, in which Figure 1 is a perspective of one form of anchoring device particularly adapted for use as a'wall tie. v
Fig. 2 is a fragmentary horizontal section of aconcrete columnhaving anchored thereto another form ofwalltie particularly adapted for use in connection with a facing material of terra cotta.
Figure 3 is a fragmentary horizontal section of a concrete column, having attached thereto a device similar to the one shown in Fig. 1, and showing the tie member bent.
Fig. 4 is a fragmentary perspective showing the outer end of the tie bent to form a loop embracing a pipe. 7
The common type of wall tie heretofore in use included a key made'of a flat strip of metal having one end interlocked with a channel member and having its'oth'er end,
adapted to be embedded between the layers of. brick or stone in a structural facing unit. Such prior forms ofties were generally satis- 40 factory for use in connection with stone or brick facings because the flat keys could lie flat in the mortar between two layers.
However, in connection with terra cotta facing units, such prior devices were objec- 5 tionable, mainly dueto the fact that the terra cotta units required wall ties capable of being bent, and the flat keys of priordevices could not be bent laterally. In the construction shown. herein, the improved anchoring device comprises an imirod aga-inst withdrawal.
The outer end of the tie rod is'bendable either transversely or "longitudinally relative to the proved form of channel memberl and a bend a bleftie' infirnbr. 7 5 1 The channel member'l is preferablyforined. ofsheetmetal and comprises an arched base part 2- anda"p air of isides 3' converging toward an openinge extending longitudinally of the channeli ja Formed inthe arched basefpart 2, is a plurality of-apertures-5 for receiving" nailsjlti which extend through the opening 4 so as to 560 be, adapted to be driven into the form, not shown. i e The sides 3 are flared outwardly-adjacent the opening 4 toprovide flanges 7adaptedto bite into the 'form,"ui1'der the pressure of-the r 6, for making a tight'joint between the channel andthe'form to prevent; any concrete from ente'ring t-he opening 4 In th r rms shown; in Figs. 2 and 3, the

The depth of the hook 10 is less than that of the channel so as to allow considerable space at the inner part of the channel in which the hook may be turned.

In the form shown in Figure 4, the outer end of the tie rod is bent to form a loop 14 for embracing a pipe 15. The rod is provided with apertures 16 for receiving a bolt 17. Whenthedevieeis ,used as a. pipe hanger, as shownfin Fig.4, the channel member 1: is embedded in the ceiling.

leaving the channel embedded in the concrete. The tie is then inserted through the opening e and turned so: asto bring: the
