1 Specification of Letters Patent.
Application filed June 24, 1913. Serial No. 775,499..
To all whom it may concern:
Be it known that I, CHARLES B. HARP, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Building-Tie, of which the following is a specification.
This invention relates to a tie adapted for securing together parts of a building, particularly the parts of a wall structure consisting of inner and outer slabs and a stud. In addition to this function the device also serves to form a shoe which becomes a part of the end of the stud and forms a bearing plate on the end ofthe stud, preventing the corners of the stud from crumbling.
Ina previous application of mine filed August 2nd, 1912, Serial No. 712,881, I have I have shown a metallic end plate for a shown a tie which accomplishes the functions of fastening the parts of the wall and the stud together, but does not protect the corners of the stud except incidentally and only partially. In another application of mine filed May 22nd, 1913, Serial No. 769,311,
building stud which is a part of the stud and which protects the corners thereof from crumbling, but such latter plate does not act in any way to form a tie to lock the inner and outer slabs to the stud.
The object of the present invention is to provide a device which isso constructed that it will produce the results produced by both of the foregoing inventions. Thus in one device I obtain the results which to obtain heretofore have required three devices, viz., the protecting plate for the end of the stud and two ties to extend across on opposite sides of the stud to unite the inner and outer slabs with the stud. In the present invention, I do not form the device of a single piece of metal, but construct it as a built up unit consisting of five pieces. This requires but a trifle more material than would be required in constructing it of a single piece of material, and although it is a built up unit of several pieces, the device as a unit, or the amount of material in the aggregate, is about one-third of the amount rerequired to obtain the results of the two former inventions referred to. In addition to these advantages, the device is better in other ways. It gives a stronger interlocking, because, the center portion of it is molded in the stud itself, and it is so constructed 7 edge that it enablesthe anchoring of a joist and '1 permits the formation of a self releasing connection and is also capable of affording a connection for reinforcing rods of a concrete structure.
Other advantages. will be brought out in the following description.
Referring to the drawings, Figure 1 is a perspective view of theupper portion of a stud with adjacent portions of outer and inner slabs all interlocked together by'the tie. Fig. 2 is a perspective of one of the wings in detail. Fig. 3 is a perspective View of the center piece in detail. perspective view of the corner of a stud, showing the manner of knocking off the corners to" enable the attachment of the tie. Fig. 5 is a perspectiveof a portion of the wall and a joist secured-to the tie with a self releasing anchor. Fig. 6 is a perspective view of a portion of a wall with a part broken away, showing the use of atie'where a concrete girder with a metal reinforcement is employed, secured to the tie. Fig. 7 is an inverted plan of the built up unit.
The unit comprises. a center piece 1 at the and is formed with a. plurality of downturned claws 2, the lower edges of which are slightly inbent as at 3 to firmly interlock in. the stud 4;. At an intermediate point claws 5 are formed by bending down a portion of the plate. Notches 6 are formed at the inner edges of the claws 2 and notches 7 are formed at the inner edges offthe be molded on the end of the stud 4:,fso that the wings 8 are permanently embedded in the stud and the claws 2 and 5 also perma- 1 nently embedded and locked therein The plate 1 near each end is formed with trans verse corrugations 10. These corrugations act to key the mortar and produce a perfect shearing which prevents the mortar in "the joint from slipping.
Secured to each end of the plate 1 is a pair of wings 11, each wing 11 having upturned ears 12 and downturned cars 13. The downturned ears 13 have inbent edges 14 which interlock in the notches 6 and the wings 11 are attached by slipping them vertically down, so that the inbent edges 14 slide downwardly in the notches 6, thus interlocking the parts of the unit inthe manner clearly shown in Fig. 7. The wings 11 fit over the inner and outer slabs 15 and 16,
the ears 13 of each wing fitting on opposite sides of the slabs, while the innermost wings 13 also fit over the outer wings 2 of the plate 1. The upturned cars 12 of the wings 11 engage inner and outer faces of the next higher tier of irmer and outer slabs; In
order to assemble the wings 11 it is neces-' sary to chip out the corners at 17 of the stud 4 ,as indicated in Fig. 4:, to permit the claw forations 18. This enables one of the claws to be bent up at an angle as shown in Fig.
5 to receive the end 19 ofa rod 20 which is secured to a joist 21 in any desired manner,
as for example, by staples 22 with the end '23 of the rod 20 bent and driven into the joist. This forms a self releasingjoist anchor which, if the joist burns, will allow the joist to release itself fromthe wall. Thus if the joist burns, its inner portion will swing down, causing the joist to fulcrum on the inner edge of the inner slab in Fig.5, and'as the joist thus swings down it will draw the "with means for engaging a stud, wings deend 19 down out of the. hole in the claw 13 and allow the joist to fall without injuring the wall.
Fig. 6 indicates how one of the perforated claws may serve for the attachment of a reinforcing rod 24. In this view I have shown a concrete girder 25 which is reinforced by the rod 24, the latter being bentand extended through one of the perforated claws.
Each of the wings 11-is preferably provided with a central perforation 26 to allow the mortar to pass therethrough and unite with theslab.
What I claim is:
1. A building ti e for securing wall members together comprising a plate having depending claws thereon to engage with the inner faces of a wall member, and detachable wings overlapping said plate and formed with upwardly extending ears to engage a wall member, said wing being also formed with downwardly extending ears to closely engage the outer faces of the claws whereby the wings are rigidly secured against angular and longitudinal movementwith respect to the plate.
2. In combination, a center plate, means for anchoring said center plate to the end of a stud, and transversely slidable detach- .able wings at each'end of the center plate,
said wings being provided with means for engaging inner and outer wall men1bers.'
3. In combination a center plate "wlth transverse corrugations at each end, and detachable wings at each end, said center plate being formed with means for anchor in'g it to a stud, said wings being provided with means for engaging wall members.
4. In combination a center plate with end claws and intermediate'claws adapted to engage a stud, detachable wings at each end of the center plate projecting laterally therefrom, and each of said wings having claws adapted to engage inner and outer wall slabs.
5. In combination a center plate with end claws and intermediate claws adapted to engage a stud, detachable wings-at each end of the center plate projecting laterally therefrom, and each of said wings having claws adapted .to engage inner and outer wall slabs, said claws having perforations for the attachment of joist anchoring rods.
6. In combination a center plate provided claws.
8.. In combination, a center plate provided with downturned claws adapted to anchor a plate to a stud, and wings detachably secured to the ends of said plate, each of said wings having upturned claws and downturned claws, each of said wings having a perforation for the passage of mortar.
In testimony whereof, I have hereunto set my hand at lLos Angeles, California this 18th day of June 1913.
