May v26, 1931. B. E. BROWN ADJUSTABLE SUPPORT FOR ANGLE BARS Filed Feb. 19. 1930 INVENTOR ATTORNEYS' 1 Patented May 2,` 1931 I' i Laatse- This invention relates tothe Aprovision ,of

a Vsecure and yet adjustable support in the poured-in concrete structural nias'sy of Vfa building whereby, when 'the finishing of thel `:5i exterior vof thebu'ilding calls for the application 'to the outside'surface of the `C Olficretel of a 'layer Of brick, terra cotta,'or :the like, the support for thejlower courses thereof may bepvery 'accurately positioned by the Ia use of .plain angle ,irons infconjunction with the elements `hereinfto bede'scrbedQ This becomes 'of spfecialrimportance where, vas is generally thecaseya's regards thesequence of steps .in the complet-ionof lan office; build- I5 ing, fit is `intended that the lo'wer twoyor three stories shall bei of highly ,polished granite, marble Vor the like, the Vslabs 'of which are,.for `the sake vof ,avoiding injury during the kstructural operations, put in posi-V 2G tion only. shortly before the building iscompleted. This `involves the starting ofl theV brick work or terra cotta, which is telformI the facing of; the upper structure, without waiting forthe installation of these lower course granite blocks,.consequently in'o'rder that the I'it of these `l'attermay be mathematical'ly exact with referenceto'the already placed brick facings thereof, Vgreaft accuracy of adjustment is necessaryV as to the strucrao; tural iron or steel parts, suchy as angle irons,

which lare generally employed tofsu'pport the lowernost course of theV brick structure meantime.

Previous `use of angle, irons vfor this pur- 351 pose of which I ain aware, has involvedtheir support relatively to the Vbuilding structure V by means; of bolts or other elementspassing through holes which must. be very carefully;

Figure 12 is a plan view from above of the clip shown in Figure l1.

A indicates a cement or other permanent structural part of a building wall, into which there are sunk, at desired intervals and embeddingly surrounded by the pouredin cement, boxes or shell pieces B, preferably provided with vertically extending bottom portions C and with flanges D, which, when the cement has hardened, are designed to lie substantially coincidentally with the plane of the outer surface thereof. If desired, the box may be provided with flanges or projections B which serve to additionally eiect the anchorage of the box in the concrete mass. In Figures 3 and 6 I have shown temporary wooden forms F for the confinement of the cement while plastic within desired limits, to the inner faces of which the flanges D of the box A are secured as by means of holding nails or bolts Gr when the wooden forms are erected andbefore the pouring in of the cement is begun. Positioned within the space E, formed by the boX, is a threaded bolt H which passes through suitably positioned and threaded apertures in the top holding clip J and the hanger K, the former of which it will be noted is of cross-sectionally L-shaped, while the latter which, as brought out particularly in Figure 6, is of a straightened-out Z-shaped form in that its top web or flange K, through which the bolt H engages, and its lower web K2, extend from opposite edges of the central portion K and in opposite directions.

The outer or shorter depending end J of the clip J is provided with a threaded hole through which the adjusting nut L extends for the engagement of its inner end against the vertically positioned portion M of the angle iron whose elbow and whose Vhorizontal section N, rest upon the flange K2 of the hanger K. Upon this horizontal flange or web N are desired to rest the brick courses Q, with which the building is to be faced.

The cement having hardened and the box B being accurately held fixedly in position therewithin, careful measurement relatively to the ground line of the building under construction is indulged in to determine very accurately the exact level at whichthe lowermost brick course Q is to be placed, and this having been ascertained, the angle iron is rested in the lower elbow of the hanger K and by manipulation of' the screw H, the latter is raised or lowered until the top surface of the horizontal flange N of the angle iron is at the exact level desired. This involves not only the hand-actuated movement upward and downward within the box of the top flange K of the hanger K, but as well, the movement accordingly of the clip J and the clamping of its bolt or screw L against the vertical web M of the angle iron. Since these constructions are placed at desired intervals in general horizontal alignment, this will resultV in the angle iron being accurately and firmly held throughout its length at just the elevation desired, and laying of the brick courses may proceed accordingly. Generally it is preferable that the inner edges of the brick thus employed shall be spaced from the hardened concrete surface to permit the slushing-in of mortar or other holding element. As to the space P shown in Figure 6 as separating the flange M of the angle iron from the line of the inner face of the depending clip end J this is relatively thin, but since in some cases the wooden forms when lilled in with concrete may bulge outwardly somewhat in places, it may at times be desirable to move one or more of the angle iron supports outwardly somewhat to compensate for this and keep the angle iron as finally positioned in true alignment. T o effect this, it may be necessary to move the angle iron outwardly somewhat relatively to the bracket K, and this may be easily done when needed by retracting the holding bolt L slightly accordingly and placin between the vertical web M of the angle iron and the central portion of the holder K a shim or ller of desired thickness, such as I have indicated at O in Figure 6. By contrast, however, the indicated inner line of the courses of brick being substantially coincident with the outer face of the wooden form F, whose further utility has been terminated by the hardening of the concrete, a much wider space for the slushed-in mortar would be available, and the greatest space of all, affording as well an interlock for the mortar when hardened, due to the presence therein of the bolt H, is afforded by the box-surrounded space E. i

In the slightly variant forms of box or shell structure illustrated in horizontal section in Figures 7 and 8 respectively, the slidable up and down movement of the hanger and the clip relatively to the box and their actuation accordingly by the screw H, is substantially the same, but in the form shown in Figure 7 the guiding rib R on either side of the box structure and the cutting Yaway accordingly of the hanger and clip indicated at S, is positioned slightly within the outer or exposed face of the box structure, whereas in Figure 8 the flanges T of the box structure, and cut-away portion V of these movable elements are positioned at the outer edge or face of the box. In either form, however, the functioning of these parts relatively to the angle iron M upon which the brick courses Q, are supported, is the same.

What I claim is:

l. Means for affording an adjustable Ilo iis

structural support for an angle ironupon which finishing I courses of brick are designed to be rested along the face of a previously erected struct-ure, comprising a shell adapted to be fixed in position relatively to said previously erected structure during its construction, an adjusting screw rotatably positioned within saidv shell, and a plurality of angled members 'operatively connected with said adjusting screw and adapted to cooperatively engage the vertical web portion of au angle bar, the horizontally eX- tending web of which is supported from beneath by a laterally projecting portion of one of said angled'members.

2. In combination with a supporting structural body, shell members each of which has an outwardly facing open side of an interposed angle iron, the other web of vwhich latter is adapted to be supported from beneath by a laterally projecting portion of one of said angled supporting members.

3. The combination, with an open-sided shell member, of a screw member rotatably supported therewithin, and a pair of cooperating angled supporting members each operatively connected with said screw member for effecting their raising and lowering relatively to said shell member, said angled supporting members being adapted to operatively and supportingly engage and carry with them an angle iron whose adjusted positioning relatively to said shell member is desired. l

4. In combination with a shell member adapted for associationv with a cementitious structural mass, a screw member rotatably supported within said shell member, a pair of partially projectingmembers each oper- .atively connected with said screw memberv and adapted to be moved upwardly or downwardly relatively to said shell member by the actuated movement of said screw members, said partially projecting members being adapted Vto cooperatively engage an interposed angle bar and to effect the regulated positioning thereof relatively tov vsaid shell member'according to their `screw-actuated movement. l i

5. The combination, .with a supporting structure, of a plurality ofshell members Vlocated* at selected intervals thereon in general and approximate alignment, a screw member rotatably supported by each of said shell members, a pair of member appurtenant each of said shell members and operatively connected with the corresponding screw member, adapted to cooperatively engage that portion of an interposed angle iron located opposite Itheir corresponding shell'member, and means appurtenant each of said shell members and their associated parts whereby irregularities in its alignedV positioning may be compensated for as re-V gards the seizure and 'supportof the adjacent portion of an angle iron byV said cof operative members. .l

. 6. An adjustable angle-iron support adapted for integrated structural association with a supporting body, comprising, in combination, a supporting shell member, a pair of angle-iron-engaging members slidably positionedpartly withinV said shell and operatively'held thereby within Va limited path of possible travel, and a rotatable screw member positioned within said shell and operatively connected with said ,angle-ironengaging` members, whereby the latter may be regulatedly moved upwardly or downwardly with respect to the shell.

7. In combination with a pairof angled 95 members between whichan angle iron is adapted to be positioned, a support-ing shell vstructure relatively to which said angled members are limitedly movable, said shell structure being adapted tobe positioned in an exposed surface portion of an erected structure, and a screw memberrotatably Vsupported by said shell and operatively connected with said angled members, whereby the latter and their supported angle iron section may be regulatedly moved upwardly or downwardly relatively to said shell structure. j

In testimony whereof I sign this specication. 11o
