REIRFbRCED-CONCRETE PARTITION.

Specification of Letters-Patent.

Patented Nov. 2, 1909.

- To all whom it may concern:

Be it known that I, GEORGE MJGRAHAM,

. a citizen of the United States of America,

and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain'new and useful Improvements in Refollowing is a specification. I

This invention relates to that type of reinforced concrete buildings which constitutes the subject matter of my prior patent No. 865,490 of Sept. 10, 1907 and has for its object to provlde a simple and efficient means for securing the perforated sheet lathing at the rear of the skeleton reinforcing wire web of a reinforced concrete partition or other like vertical ing, in a'ready and su stantial manner, all as will hereinafter more fully appear.

In the accompanying drawings :Figure l is an elevation of a partition with parts broken away to illustrate the present improvement. Fi .2 is a horizontal section of the same on line w'm, Fig. 1. Fig. 3 is a detail elevation .of a link in an open condition previous to its application. Fig. A, is a similar view of the link in its closed condition. p

Similar numerals of reference indicate like parts in the different views.

inforced-Ooncrete Partitions, of which the' Referring to the drawings, 1 representsv the reinforcing wires of a partition or other vertical portion of a reinforced concrete building, and which wires under proper and uniform tension constitute the metal reinforcing center for apartition or the like, as set forth in detail in my aforesaid patent NO. 865,490, of Sept. 10,1907. I

2 is the perforated lathing sheet of expanded metal or the like, and which in the present construction is arranged to the rear of the skeleton wire center 1, and secured in place by the tie or clip pieces thereinafter described, to receive the imposed mass ortion of the buildof the artition or other vertical portion of the bui ding. N

The feature ofnovelty in the present improvement lies wholly in the construction of the aforesaid tie or clip piece l, so that the same can be easilyv and rapidl applied to afford a strong and substantia connection and which by the avoidance of any extended projection of the clip at front permits of the formation of a very thin partition and 56 at the same time oifers a minimum interference with'the finishing Operation upon the face of the concrete mass. To the above ends the said clips are formed of wire and initially have the quadrilateral form shown 60 in Fig. 3, with one of the corners thereof cut' away to form the gap or opening 5 and a pair of free prongs 6, which are capable of ready and convenient introduction around the reinforcing wires 1 and through the per- 'forations of the lathing 2, after which the 1 clips are clenched or set by a suitable tool into the substantially triangular form shown in Figs. 2 and 4 with the free prongs 6 overlapping each other as shown.

Having thus fully described my said invention what Iclaim as new and desire to secure by Letters Patent, is:-

The combination in .a reinforced concrete partition,.of a series ofreinforcing wires in crossed relation, perforated'sheet lathing arran ed at one side of said Wires, and clips app ied to said ires at their intersecting points and embracing adjacent portions of the perforated lathing to secure the parts togcther, said cli s having an open quadrilateral form initia ly, substantiallyas set forth. Signed at Chicago, Illinois this 2nd day of October 1907. 9
