ANCHOR.

Application iiled'October 15, 1926. Serial No."141,6876.

.and it is important that the arrangement 4be such that the two men in cooperation can readily and easily apply and tighten the bars in approximately their final adjusted posi` tion. It is likewise important that the bars be capable of ready adjustment later by one workman or by twoworkmen at they most to their final adjusted position for supporting the courses of stone or brick to be carried thereby in accurately adjusted position with respect to thefother courses adjacent thereto. It is also important that the hangersl be of such an arrangement that they can be tightened properly without danger of breakage and that the hangers when tightened shall have a substantially positive gripping effect on the angle bars of such strength as to be effective without material danger of failure.

It is the object of my invention to, provide a construction ofthis type having the several desirable features above outlined, so that the angle bars can be placed quickly and easily in the desired adjusted position and that the facing portions of the wall shall be securely and safely supported thereon. It is another object of my invent-ion to improve devices of this type in sundry details hereinafter pointed out. The preferred means by which I have accomplished my several objects are illustrated in the drawing and are hereinafter specifically described. What I desire to cover by Letters Patent is set forth in the claims.

In the drawing,-

Fig. 1 is a face view showing fragmentary portions of an angle bar supported in position on the face of a concrete wall ready for the application of brick or stone Work thereto.

Fig. 2 is a vertical cross section taken sub-k stantially at line 2 2 of Fig. 1, and showing in dotted lines the forms between which the wall was molded.

Fig. 3 is a vertical cross section through my improved insert box of the type preferably used in connection with a concrete wall structure, and showing in dotted lines a changed position of the securing bolt.

Fig. 4 is a face view of the box of Fig. 3.

Fig. 5 is a View similar to a portion of Fig.

3, but showing a modifiedy form of construction.

Fig. 6 is a 'face View of a modified form of" insert box.

Fig. 7 is a vertical cross section through an 'I-beam forming a part 'of the frameworkof a steel building and having my improved anchor device mounted thereon; and

Fig. 8 is alview similar to Fig. 7 but showing a modified arrangement and including a box for Iprotecting the bolt and its associated pars from the concrete to be placed about the stee f Referring now particularly to Figsiil to 4 inclusive, 15 indicates a concrete wall having been molded between forms 16 of any suitable type and provided at intervals therealong with insert boxes 17 embodied in the wall fory adjustably holding in position securing bolts 18 by which an angle bar 19 is adjustably secured in position for supporting the facing portion of thewall. As the art7 it is dicult to curately in position so that a plurality of the boxes may be in perfect alignment in the iinished and hardened wall, wherefore it is necesy sary or important that the boxes be provided with adjustable means for supporting the bolts 18so that the bolts may be placed in the desired alignment regardless of thev slight discrepancies in the positionof the boxes. .It is also important that the entire set of'bolts 18y for one of the angle bars 19 be adjustable similarly up and down so thatthe bar 19 can be placedL accurately in position with 'respect to is well understood in place the boxes 17k acthe facing portion of the wall below regardf f less of slight variations in the position of such facing portions so that the bar 19 can sup,-

port the knext higher course of stone or brick in the desired relationship to `the courses below. The'vertical adjustment of the bolts 18 j with respect to the boxes is effected in `the manner hereinafter described, while the horif zontal ladjustment is ksecured by the provi-` sion of horizontally disposed slots 20 for the bolts18 in the vertically extending Aportion ofy the bar 19.

The insert boxesy 17 in the `embodiment L shown in Figs. 1 to 4: are in the form ofk castings comprising side walls 21, a top wall 22 and a bottom wall 23, with a back wall 24 formed integrally with ythe other walls and i comprising an outwardly ,extending flange 25 about the entire periphery of thefbox. ,In

` the construction shownthe side walls 21 conj verge downwardly with respect to each other so as to 'providea vertical support for'the box within the concrete wall even though the bottom face of the box is flush with thebot-y tom edge face of the wall, as is sometimes the case. By the provisionvof the flange 25, the

box is secured very strongly in position withV respect to a forward pull upon the box by which the box might otherwisebe drawn for wardly out of position within the wall.

In thefconstruction f shown, the front wall portion of the box is in the form of a wedge indicated by the numeral 26, having its front :n and rear faces diverging slightly downwardly, the front face of thewedge 4member being adaptedl to conform to the vertical position ofthe rear faceof the bar 119 Jwhile the rear face of the wedge member diverges down-k l Iwardly toa slight 4degree with respect to the rear face of thebar 19. r1he side edges of the wedge member 26 merge 1 withk the side walls 21.0f the box throughout the full thickness of the wedge so as to provide the desired support for the wedge memberwith respect to the outer face of the form 16.

the workman in placing the boxes in properv with respect` thereto.v

box.

In forming the-wall 15, a plurality of the boxes 17Yare secured in position upon the form 16`with-the front faces of the boxes' iin contact withthe form, kthe boxes being.

very firmly secured in position upon the form by the use 'fof heavy nails 27 vextending through openings 27a through the box, such nails being preferably Yclinched upon vthe :Forv assisting rangement being such that the head -portioriDs of the bolts can beientered through the Venlarged lportions of`the T-slots after the boxes are'in position. In theI form shown in Figs. `1to 4, the bolts 18 are standard .vbolts'having square ',heads, being provided with auxiliary head members 29'in the form of iheavy washers. In the construction here shown, the head members 29 `are cut away at opposite sides'so as to provide lugs 3() at oppo Ysite :sides of the bolt' for engagement in the slots 28 for holding thewashers againstrotation, thevwashers being cut diagonally so as Vto provide extended bearing faces for the bolts at an angle conforming tothe inclination of the rear faces lof the wedgemembers 26. The

washers 29'; are provided inthe construction shown with `lugs 31 engaging the heads of the u bolts 18 :for holding the bolts against rotation 'when a is desired 'C0-apply an angie bar 19 in position, twoworkmenl handle the opposite ends of the bari for inserting the bolts of the end-boxes 17 through the slots 20 at the ends of thebar, the nuts on the bolts 18 being screwed up sufliciently for holding the bar loosely in position. The bolts 18 of the intermediate boxes 17 vare then inserted through the corresponding intermediate slots 20 of the bar 19 and the nuts are threaded upon their outer ends. kFor enabling the intermediate bolts 18 to be inserted readily through their slots 20,,it is importantthat the bolts be capable of retraction almost completely into the boxes,f as shown by the dotted line position of the bolt in Fig. 3, the box 17 being formed of a size toenable such manipulation of the parts. When the bar 19 is to be tightened into position., the ends of the bar are placed at the desired height and the nuts on the end' bolts are tightened into position. Aswill be readily seen, when it is desired to adjust the bar 19 vertically after all of the bolts 18are in position through the slots 20, this can be accomplished readily by vertical movement of the ends of the bar in unison or by an adjustment ofl either end of the bar by itself, the intermediate bolts 18 being adapted to move without-resistance either upwardly or downwardly along the slots 28 of the intermediate boxes. When the bar has been tightened into position at its ends, the intermediate bolts 18 are also tightened, and all of the bolts, so far as is necessary or advisable,

are cut oif so as notto interfere with the courses of brick or stone.

As will be readily understood, when one of the bolts 18 is tightened in position by the nut on the outer face of the bar 19, the bar is held positively against downward movement, inasmuch as such downward movement would necessitate a greater length of bolt. The inclination of the rear face of the wedge member 26 is so slight that at lthe same time the bar 19 is held very strongly by friction against upward movement with respect to the wedge member 26, the frictional engagement between the head portion of the bolt and the rear face of the wedge being very great by reason of the fact that the head portion is beveledto correspond with the angle of the wedge. By reason of the very slight taper of the wedge member 26, the distance between the rear face of the wedge at the bottom of the box and the front face of the bar 19 is kept within practical limits so that the support for the bolt 18 shall be kept adequate even when the bolt is-adj usted to its lowermost position in the slot 28. y

In Fig. 5,1 have shown a modified form comprising a` bolt 32 having its head 33 cut away aty the sides to conform to the slant of the wedge 26 and for holding the bolt against rotation with respect to the wedge without the use of an auxiliary head member or washer 29. In cases where a bolt of the type shown in Fig. 5 can be obtained to advantage, this construction is to be preferred to the construction illustrated in Fig. 3. The operation of the two devices is substantially the same.

In Fig. I have shown a modified form of insert box in which the side walls 34 parallel instead of beingconvergent downwardly as in Fig. 4. 'Io compensate for this change so as to provide the desired vertical support, I have provided laterally projecting ribs 35 extending across the side walls 34 in spaced relation to the lower end of the box, in the construction shown the ribs 35 being placed at the top of the box. Inasmuch as the construction is otherwise substantially in accordance with that above described, it is believed to be unnecessary to describe the same herein, the operationbeing substantially as above described.

In Fig. I have shown my improved an choring means applied directly to the fabri# cated steel frame of a building. In this construction, an angle 36 is riveted to the web ot' an I-beam 37 of the framework, with a second .angle 38 riveted thereto. The angle 38 is provided with aI vertically disposed slot 39 corresponding to the slot 28 of the construction shown in Fig. 4. A wedge member 40, preferably in the form of a casting or a stampl` ing and having its rear face diverging downwardly with respect to its front face which is defined by the edges ot the llange portions, is secured by means of a rivet or other form of bolt 4l upon the angle 38, the wedge member 40 being provided with a slot 42 corre* spending in shape, size and position with the slot 39. A plurality of such supporting parts are provided along the I-beam 37 or along other parts in the desired alignment for sup* porting an angle bar 43 by means ot bolts 44, the bolts 44 in the construction illustrated in F ig. 7 corresponding with the bolts 32 of Fig. 5 rather than with the construction shown in Fig. 3. Inasmuch as the operation of the parts here described corresponds exactly with that above described in connection with Figs.

' l to 4, it is believed to be unnecessary to describe it further.

In F 8, the construction is the same as that shown in Fig. 7, except that the slot 45 is formed directly in the web of the beam 46 of the frame work of the building, the beam 46 being shown as a channel beam rather than an I-beam. In the construction shown in F i g. 8, the angle bar 47 is also shown with its outwardly extending flange at the top rather than at the bottom as in the remaining ligures. The bolt 44 and wedge member 40 are also enclosed at the rear tace of the beam 46 by means of a sheet metal casing 48 preferably secured in position by welding for protecting the parts from the concrete by which the rear face of the beam is to be inelosed.

While I prefer to employ the construction as illustrated in my drawing and as above described., it will be understood that I do not wish to limit my invention to the use of the features there illustra-ted except asthe claims are hereinafter specifically so limited, since it will be understood that changes may well be made in the construction without departing from the spirit of my invention.
