FORM FOR HOLDING CONCRETE 11F/TALES.

Application led July 21, 1922.

7 7o all whom t may concern.'

Be it known that l, FLnMrNc l-l. Puck., a citizen of the United States ot America. and resident ot the citiot Seattle. in tbe county ot King and State ot Washington. have invented certain new and useful lmprovements in Forms tor Molding' Concrete l/Valls ot which the -following is a specification.

My invention relates to t-he construction of forms used in molding concrete structures and consists ot certain parts constructed in such a way that they may be used as the frame work or supporting members tor the boards or like members which are used to shape the outer surface et the concrete.

The object of my invention is to provide the material used for the construction ot these forms, in such shape that it is readily adapted to all the varying sizes and forms in which it is ordinarily desired to mold concrete for structural. purposes and to have this material such that it may be quickly put in place and also quickly disassembled or taken down. f

My invention consists ot the tea-tures ot construction and novel combinations of parts which l will hereinafter describe and then particularly point out in the claims terminating this specification.

In the accompanying drawings l have shown my invention in a construction which is that now most preferred by me.

Figure 1. is a top or plan view ot my invention as applied to the formino' ot a corner in a foundation wall.

Figure 2 is a side view or elevation ot the same parts.

Figure 3 is a sectional elevation showing enough construction to indicate the manner of applying this in the molding ot ordinary Wall.

Figure 4 shows., in perspective, the manner of placing the mold for two walls joining at the corner.

Figure 5 is a sectional elevation showing slightly modified construction ot one ot the parts.

In the formation ot concrete walls the cost ot constructinga the molds mounts often to a very considerable item. lt is a purpose of this invention to provide a construction of certain parts, such that they may be user.. to quickly assemble these molds and such that after the concrete wall has been formed Serial N10. 576,428.

and set, the molds may be quickly taken down and without destroyingl the parts thereof, so that these may be again used at other points. The chief and novel teatures lie in the construction ot the posts which are employed tor holdingl the boards used in their proper place and the manner ot supporting these in proper position and securing' the board thereto.

For the posts to which the boards are to be secured. l employ rolled metal sections. these being` cut ot a suitable length. These posts may be made ot1 different sections. but

the section which l most prefer to use F the angle bar. These bars l have a series ot holes, l0., distributed at short distances along` the length ot both flanges thereof and preferably well toward the outer eda'es of the flanges as thus it will be easy to drive nails through these holes. These holes are provided in both flanges, so that either ange ot the angle bar may be used against which to secure the boards. rllhe boards 2 are placed against the 'faces ot post l, and small nails inserted in the holes 10 and driven into the wood. Preferably these nails should be of such a length that they will not pierce the opposite? or inner tace ot the boards.

rllhe ends of the bars l are provided with notches 1l.. which are preferably made at the junction ot the two flanges. These notches may be lil-shaped or square at the bottom as desired. The ends the bars may be secured together by usino' a rod. as 3, which has its ends bent laterally to torni offset sections or hooks 31 which hook over the outside ot the bars and which prevent their separatingV beyond a certain distance. rThese connecting rods 3 may be straight, except for a single bend 30 at the ends or they may be made as shown in Figure 5.` wherein they are bent to form a trl-shaped end 31. the two sides ot which are shaped so as to snugly tit over the flange of the angle bar. In this case these rods act as spacers to prevent the bars 1 from being brought together and also as tie rods to prevent separation. The spacing apart ot the two walls of the mold may be secured. b v the insertion of wood blocks which would be removed before they become buried in the concrete, or in any other suitable manner.

Where the length of the posts l which are being employed is so great that supporting AJU tie rods are needed between their ends, this may be secured by using Wires, as t, Which connect opposite posts and Which may be left in the Wall. These Wires may be made of such a size that they may be passed through the holes l in the flange, as is 'shown in Figure 3, or they may be passed entirely around the angle bars, as is shown in Figures 1 and 2. These Wires may be passed between adjacent edges of two of the boards which forni the Walls. The ends of the Wire may be twisted together and this joint may be inade at any point desired, either Within the space to be occupied by the Wall or outside of the forms. When it is desired to take down the Tterms, these Wires will be cut and the ends which project from the finished Wall will be cut oli' flush with the Wall, by the use of Wire cutters.

l prefer to provide the ends of the bars l with a hole of such size that a rod 50 of material size may be passed therethrough. Such a rod may be employed for connecting a number oit' posts l and thus, at times, help to keep the posts together and to assist in the construction of the molds. The rods 5 may, Whenever desir-ed, be provided with spacers which will hold the posts 1 definite distances apart.

After the concrete has been poured in a mold and has been set so that it is desired to remove the molds, the tie rods 3 are readily removed. rlhe tie rods 3 Which connect the lovver ends of the bars l, must be left in the Wall, if they vvare used at this point. rihe tie wires 4: may also be cut. lt is then an easy matter to pry the bars 1 free from the boa-rds 2, as. the nails used .to secure the boards in place are small and the holes in the bars through which the nails pass lit snugly around the nail and, in consequence, the material forming the molds need not be broken in knocking down the molds. It may therefore be substantially all used again 'for forming molds.

What I claim as my invention is:

1. A' post for use in forming molds ior concrete Walls consisting of an angle bar having nail -holes distributed along its flanges and notches opening at their ends and adapted ifcr the reception o-t tie rods.

2. A form for use in molding concrete walls comprising aser-ies of angle bars hav ing nail receiving holes spaced along their iianges, and boards secured by nails driven through said holes, and tie rods having hooked ends adapted to engage posts at opposite sides of the wall to prevent their separation.

3. A forni for use in molding concrete walls comprising a series of angle bars having nail receiving holes spaced along their flanges, and notches in their ends, tie rods having hooked ends adapted to enter said notches, and boards secu-red by nails driven through said holes.

4i. A post for use in making vforms for concrete Walls comprising an angle bar having nail-receiving holes spaced along its flanges and a notch opening` at its end and including the bases of each flange and adapted for the reception of tie rods.

5. A form construction for concrete Walls comprising posts composed oi" angle bars provided with nail-receiving holes` in, their flanges and a notch in each end located at the point Where the tWo flangesjoin, and tie rods having laterally bent ends and adapted to enter said notches and to hold together pposite sides of the Wall.

Signed at Seattle, King County, Washington this th day of July, 1922.
