Tojall whom "it may concern:

Be it known that I, GEORGE J. Sci-mp1s, a cit zen of the'United States of America, re-

siding at Sandusky, in the county of Erie and State of Ohio, have invented certain new and useful Improvements inMet-al-Re- .y inforced-Concrete Columns, Posts, and the l Like; and I hereby declare the following to,

be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which. it pertains to make and use. the same.

,This nvention relates to metal-reinforced concrete columns, posts and the like, and has met'al'reinforcement which will render the for one of its objects the provision of a column or section stronger and more reliable thanthe metal reinforced sections heretofore made. I I V further object'is the provision of a concrete columnhaving a metal reinforcement which is inherently strong and rigid and consistsof parts which can be easily and securely united or fastened together.

With these objects in'view, this invention consists in certain novel details of construction and combinations and arrangements of '-'metal reinforcement arranged and construct-.

ed in accordance with my invention, the con-' creteportion of the upper part of the column'being-broken away. "Fig. 2 is a transverse "secti'on substantially along the line '22, Fig. 1, looking downwardly. Fig. 3 is a vertical section of a portion of the metal reinforcement, the section being taken sub- 'stantially along the line .3--3 of'F 1g. 2, looking in the direction indicated by the arrow.

. Fig. 4: is a vertical section of a portion of the. metal reinforcement, the section being,

taken substantially along. the line 4.4, Fig. Fig. 5 is an elevation ing together certain parts of the metal re- The vertical metal -.reinforced concrete "column, shown in Figs. 1 and 2, may be of any shapebut as here shown is rectangular in cross fsection, forming whatis known as a square column;

The metal reinforcement for the column is of courseeinbedded in the concrete 10'and f includes, a group or pluralityof vertical or substantially parallel upright rods 11 which I have here shown four rods arranged in rectangular formation opposite or diagonally inward from the different corners re spectivelyof the column. i J

The vertical or longitudinally extending or parallel rods 11' are tied or secured together so' as to provide a metal reinforcement of considerable inherent strength and stiffness, and the means which I employ for this-purpose includes a'rod 12 which is arranged spirally about the group of upright and parallel rods and has its convolutions rigidly secured to and held in engagement wi'tli'the outer sides of the said parallel rods. As here shown the spiral rod 1201' the convolutions thereof include portions 12 which are inclined with respect to theaxis of the column and with respect to the vertical rods, as shown in Fig. 1, and are in planes parallel respectively to the sides of the column, as shown .in Fig. 2, and portions 1'2 arranged opposite the corners of the column column, as shown in Fig. 4:, and inclined with respect to the sides of the column, as shown in Fig. 2, said portions 12 'being, in engagement with and crossing the'diflerent vertical or upright rods 11. i H

To secure the convolutionsof the spiral rod 12 to the parallel rods 11', Ifemploy sheet-metal clips, each of which is provided with 'a central portion forming a loop 13 which is radially arranged relative to the inner side of or receives one ofthe vertical rods 11, and having substantially paraloutwardly bQYOllClfl-IG spiral rod and are thence doubled or-re'turned. inwardly, formthe clip being substantially?parallel to the

sides

14 and 15. formed by the two side loops 16 and '17 or the parallel sides 14 and lo and .19 and 19 of the clip are provided withinwardly exof these vertical-rods may be employed but lel sides-14: and 15 which extend radially and inclined with respect to'the axis of the center of the column and extends around the The outer portions of the clip which are tending open slots 20 which ,as shown clearly inl 'igs. 1 4 and 5, are inclined with respect to the axls of the column, and the two slots 1n the difierent side loops or outer portions respectively of the clip are arranged the one higher than the other and receive a section of one of the convolutions of the spiral rod, in this case receiving-one of the portions 12 of the rod. The slots 20 extend inwardly a sufficient distance to permit the portion 12 of the spiral rod to bear inwardly againstthe outer side of the corresponding vertical rod 11.

To clamp or hold the convolutions of the spiral rod 12 against the rods 11, clamping members or securing devices, such, for instance, as tapered or wedge-shaped members 21 are inserted between the spiral rod 12 and the bases or central portions of'the 'side loops ,6 and 17 of each clip and are preferably driven into place so as to form a very rigid metal-reinforcing structure.

The clips and wedges will be employed for clamping or securing each convolution of the spiral rod 12 to all the vertical rods 11 so that the spiral rod is secured to each vertical rod at a large number of vertically spaced points. 1

I do not desire to be confined to the exact details shown but aim in my claims to cover all modifications which do not involve a departure from .the' spirit and scope of my invention.
