6 Claims.

This invention relates` to building structures and particularly to the construction of walls thereofr having a main cementitious bodyportion or main element which is usually faced with blocks 5,ofbriolr or tile laid in courses and it is the prmary object of thisinvention to provide a tie forr the component parts of the building` wall which willl effectually tie the same together and which will afford relative adjustment in order that the Aanchor portion of the wall-tie might be moved -to the operative position between the courses of blocks.

One of the objects ofthe invention is to provide a wall-'tie for the above mentioned purpose, which includes simply constructed inter-engaging parts, one of which, being a channel of special contour, is susceptible of being imbedded in the concrete main building structure in a man-y ner which precludes its pulling out and which `presents an effective engaging groove in the main building structure that is lined to receive one end of a laterally projecting anchor. v

Another object of the invention is the provision of a wall-tie chor formed to present inter-engaging undulations, the undulations of the channel being formed longitudinally of the sides thereof and preferably extendingtheir full length. The un'- dulations ofthe anchor beingY formed at `the opposite edges thereof to inter-engage the channel sides in a manner which Ypermits relative longitudinal.- movement along the channel, yet precludes lateral movement or displacement after the channel and anchor have been operatively associated.

VSpecific details of construction which enter into the manufacture of awall-tie made in accordance with this invention, and which .in this instance are extremely important, will be clearly broughtV forth in the following specification, referring to the accompanying drawing wherein Figure-.1 isa fragmentary View of abuilding structure showing the componentparts of the wall being: secured together by a wall-tie made in accordance with thisinvention.

Fig. 2 is `an enlarged perspective viewfof th preferred form of wall-tie showing channel and anchor inoperative relation.y Fig. 3 .is an enlarged fragmentary sectional View taken on line E11- III of Fig. 1 illustratinggthe parts of the building wallv and wall-tie inplace. Fig. 4 is a fragmentary cross sectional View through a modified form of channel and anchor. Fig. 5 is asimilar View showing another form of construction and having a channel and an-v Fig. 6 is a cross sectional View through an even further modification of the preferred form. y.

lLike reference characters are used hereinto designate similar parts throughout the views and the numeral 8 indicates the mainwall or element 60 .Y of a building structure which is made up by pouring concrete into forms built for the purpose and. which support the hereinafter described' channelrto be embedded therein. 10 indicates the building face which is made up of" courses 55 of. brick or tile, between which courses lies the anchor forming a part of this invention, held against lateral movement by the channel in wall 8.

Referring now to Figs. 1 to 3 inclusive and de- '70H scribing the preferred embodiment of the invention l2 indicates a base wall ofthe channel from which vprojects the sides 14 formed to present ak series of undulations 16 extending longitudinally.. of sides 14v andpreferably their entire length. 7 Sides 14 preferably have their free edges ared outwardly to present an entrance to the channel which is smooth and. unobstructed, and which joins the wall 8 in a smooth manner whichperf forms the duty of reinforcing theedge, rather M than allowing the same lto be-presented directlyr to the anchor. Suitable perforations 18 should,y be provided to permit nailing or otherwise securv ing the channel to the form for wall 8 as it is being. constructed. Sides 14v approach each 'other as-85 their free edges are approached .and awedge'- shaped cross section is presented, the sides ofr which are undulated to receive the similarly formed anchor 20 which has an edge contour atv the end entering tensive with the inner cross sectional contour of. the channel. This end 22 formed on anchor, 20l is formed during the manufacture of the anchor` by cutting the same from material in step-bystep fashion, pleted, presents a .bifurcated end 24; the inner edge of said bifurcation having the same contour asthe outer edge of 'end22. Aperpendicularly projecting lip 26 may be formed alongk the baseA of Ythe-bifurcation 24 and it is to be noted the outer end of this anchor 20 might beformed to present structure adapted to engage between courses of any material ywithout deviating from the basic function. Shoulders 28 formed'at the '105 meeting line between the body of anchor 20 and thespecially formed end 22 serve as abutments to eliminate excessive play in the event the iit between the channel and end 22 is not snug. It

is notable that anchor 20 is flared so that the new the channel which is coex- 90 ,Y

whichiwhen the anchor 20 iscom- 95 that V projected end 24 presents a greater surface than the end 22 slidably engaged by the channel.

In Fig. 4 is illustrated the rst modied form which Vdeviates from the broad principal of the 5 invention only through the specific construction of the inter-engaging end of the anchor 26 and the channel. In this instance the channel has side walls 5() disposed relatively close together'adjacent their free edges to present a neck 52 relatively narrow with respect to the main portion of the channel formed between the arcuate base wall 54 and the enlarged undulations 56 which connect wall 54 and sides 59. Flanges 58 extend to each side of the channel along the entrance thereof and the engaging end 5o of anchor 20 is'fcrmed to present a similar outline at its edge as the inner cross sectional contour vofthe channel as shown. In this instance, the shoulders 28 may be angled slightly to facilitate movement of anohor 20 longitudinally along the channel.

In Fig. 5 the channel is formed'very similarly to the channel illustrated inthe preferred einbodiment. The base wall '70 has extending there- A Y from a pair of sides 72 which are undulated longitudinally their entire length, but the undulations are rolled therein to present more abrupt corners at the points of turn, and the walls 72 in this instance arenot disposed to approach each other as their free edges are reached. The end 74 of anchor 20 which is stamped to conform to the undulations formed in the channel of this modified form may be moved laterally into and out of the channel simply by successively step-- gaping projections 'Z6 from one undulation to the other. Since the sides '72 of this form of channel are parallel, the end 'la of anchor 20 be moved along therebetween in the manner mentioned. Thus a large number of anchors engaging a channel of this form throughout a course of brick or 4,0 the like l0 may be disposed the same distance from the main wall 8 without thefuse of measuring instruments. Also, this form of tie is especial-- ly adapted to be used in tying facings to an ir- M`regularly surfaced main building element.

Y Referring to Fig. 6, wherein the third modication of the wall-tie is shown, it is to be observed that the base wall 80 has sides 82 extending therefrom which are formed to present a plu- ..vrality of parallel steps 84 which are disposed "in diiferent planes and joined by angled walls 851 in a manner which presents a cross section of the channel Vsubstantially like that shown in the preferred embodiment. The inner end 88 F.of this anchor 20 is, like all the rest, punched `to present a contour which allows all of the wall 82 and 8oy to engage lthe .edge thereof to lend strength when the tie is in the Yoperative position. The neck adjacent the entrance to this :channel is relatively narrow with respect to the main rbody and a large quantity of cementitious substance is presented in the line of lateral pull to prevent displacement of the anchored end 88.

n While a number of speciiic forms have been shown and illustrated, it is to be remembered 6`5`-that the basic concepts of the invention are directedto the novel formation of channel sides which engage the end of an anchor in a manner to lend the greatest amount of strength thereto as lateral force is exerted which would normally hpull the anchor from position and perhaps dislodge the channel. The sides of the channels are all formed to present a major amount of gripping surface, both for the anchor member and the substance from which the main wall is made. The various forms of undulations provided along the sides of these channels present surfaces to the anchor which are practically perpendicular to the direct line of pull and the construction of this wall-tie to this extent is novel and extremely valuable. This point of invention and structural feature is shown in all forms of the walltie `illustrated and described.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:
