MOLD FOR FIREPROOF CONSTRUCTION.

Specification of Letters Patent.

Patented une 18, 1907.

Application filed October 24,1906. "Serial No. 340,289.

Be it known that we, WILLIAM S. HIND- MAN and PAUL H, ANTHONY, citizens of the United States, residing at Edgeworth and Ben Avon, respectively, in the county of Allegheny and State of Pennsylvania, have invented or discovered-new and useful Improvements in Molds for Fireproof Construction, ofwhich the following is aspecification.

Our invention relatesto improvements in temporary supports or false-work for concrete columns, beams, girders, floors, and the like during the time they are being made and the cement is setting.

The object -of our invention is to provide such false-work or sup orts Which shall be readily adjustable for all the re uired widths, depths, and lengths of beams, or all the required distances for floors and girders between beams' or their equivalents, and for various 'sizesand shapes of columns. We provide temporary adjustable supports .for

oors which are not required to be supported by pillars or posts extended up to the same between adjacent beams or the like.

Referring to the drawin s which form a part of this specification, Figure 1 is an elevation of one form of our improved falsework or support, showing the linings in cross section; Fig. 2, an end view of Fig. 1, portime being omitted at each end thereof; Fig. 3, a section on the line 33 of. Fig. 5 Fig. 4, a cross-section of a columnsupport or mold, with our improved adjustable means thereon for holding it together; and Fig. 5, a section on theline 55 of Fig. 3.

troughs or molds in which the cement, reinforced with metal, if preferred, is poured and shaped. The floor and sides of the troughs A and B are preferably of wood and are indicated by the numerals 1 and 2, respectively.

The sides 2 are supported laterally by the vertical angle or other metal bars 3 having therein at different elevations a series of holes 4 and the floor 1 and the sides 2 are supported from beneath by the channel or other metal bar 5 having therein a number of holes 6 arranged in one or more horizontal series. The bar 5 is bolted to the respective vertical bars 3, as shown in Fig. 1. The channel A being wide and deep, the bar 5 has its ex- 7 treme ends secured to the lower ends of the bars 3; but the channel B being shallower and 1 narrower than the channel A, the bars 3 and 5'are secured together at their intermediate portions. It is readily seen that by arrangmg the bars 3 and 5 in various adjustments, beams of any desired depth and width may be formed between the floor 1 and the side walls 2, it being necessary, of course, to make the floor and the side walls correspond to the adjustments of the bars 3 and 5. In order to make the joints between the bars 3 and 5 are bolted between the said bars by the bolts securing the bars together and which are wider and ion er than the Width of the said bars in order t at. they may also be bolted to said bars by other bolts, as 8,. The gusset plates may extend toward each other as bebeneath the mold B.

The channel bar 5 is referablysupported by the metal tubular coihmn 9, consisting, if preferred, of telescopic .members, adjustably secured together by the bolt 10, passed through alined holes in the sections, there being several holes provided so that various adjustments may be had. The column 9 preferably has the cross-head 11 which may site ends connected to the gusset plates by the braces 13, having their upper ends bent and passed through the gusset lates, as shown at 14 in Fig. 2. If desired t e ends 14 may be assed through some of the idle holes in'the bars 3 or may be otherwise secured. The braces and also the gusset On the drawings, A and B representeach having a central vertical portion lyingv between the bars 18 and 19, an upper out Wardly extending lug or member 23 in one of the holes 21 of one bar, and another member 24 extending in the opposite direction from the lower end and lying beneath the flange or rigid, we may use the gusset plates 7 which neath the mold A, or away from each other as e adjusted on the column by means of the set-screw 12. The cross-head has its oppolower edge of the other bar. It is not necessary that the members 24 pass beneath the bars as they may pass through a second series of holes in the bars below the holes shown therein. lt is thus seen that the space between the beams may be readily adjusted by placing the clips 22 in the proper registering openings 21.

in constructing concrete columns, we prefor to bind the mold walls 25 together by means of a series of encircling devices constructed as followsi We provide for each binding device a pair of angle bars 26 sccured together by the boltZT passed through their ends. The free ends of each pair of bars are provided with the longitudinal slots 28. 'lhe free ends of one pair of bars crossthe free ends of the other pair of bars and bolts 29 are passed through the crossing slots to secure the bars together to form an inelosed figure. The interior angles of the Walls 25 are preferably provided with the corner strips 30 and the outer angles with the angle bars 31, which lie inside the bars 26. The bars 26 may be adjusted to inclose any rectangular figure by means of the bolts 29 and the slots 28. it is clear that the principles of our invention may be applied to columns of any number of sides.

lt is to be understood that the bars 3 and 5 and the supports 9 will be provided at short intervals longitudinally of the beams. It is also clear that the bars form temporary girders and that they might, if desired, be used in "building constructions as permanent girders or their equivalent. The word beam used in the claims is used generically to include all horizontal beam-likestructures, whethtu' technically beams or not.

We do not desire to restrict ourselves to the details of construction and to the precise combinations shown or described, nor do we restrict ourselves to the particular use of our invention shown or described, as it may obviously be applied. to other portions of structural work or to bridges and other classes of concrete or'reinforce'd concrete work.

\Ve clain1--- 1. In a mold for structural beams, a floor and side walls, vertical side bars to support said side walls, horizontal bars to support the said floor, means co-operating with said vertical and horizontal bars for adjusting distances apart of said vertical bars, means for adjusting the height of the horizontal bars relatively to the vertical bars, and extensible means for supporting said mold from below.

2. In a mold for structural beams, lagging to support and shape the sides and bottom of a beam, vertical bars to support the side lagging, horizontal bars to support the bottom lagging, means co-operating with said vertical and. horizontal bars, for securing said horizontal bars to the vertical bars and for adjusting the former vertically on the lat ter, and the latter horizontally on the former, and extensiblemeans for supporting the mold in its desired vertical position from below. I

In a mold for structural beams, lagging to support and shape the sides and bottom of a beam, vertical bars to support the side lagging, a horizontal bar arranged to support the bottom lagging and having its ends crossing said vertical bars, said bars being provided with longitudinal series of holes, and securing means passed through registering holes in said bars, and extensible means for supporting the mold from below.

4. A girder composed of overlapping bars each having a'longitudinal series of holes, and fastening devices, each having one member in one of the holes of one bar, and another member supporting the other bar.

5. A girder composed of overlapping bars each having a longitudinal series of holes, and fasteningdevices, each ht ving one member in one of the holes of one bar, and another member in engagement with the bottom of the lower edge of the other bar.

6. A girder composed of overlapping bars and fastening devices, each having a portion lying between the bars and two lateral members, one in supporting engagement with each bar.

7. A mold for structural work comprising lagging for beams and the structural connections between beams, vertical and horizontal bars, means for adjustably securing them together to support the sides and bottom of each beam, overlapping horizontal bars, each having one end secured to a vertical bar, and means for supporting the overlapping portions of said bars, comprising clips each having oppositely extending members, one member being supported by one -bar andsupporting the other bar.

8. A mold for columns consisting of a casing, and encircling bands for supporting the same, the bands being composed of pairs of bars, means for securing the ends of each pair permanently together, the remaining ends of each pair slotted and crossing the ends of the other pair, and means in the slots for adju stably securing together said crossing ends.
