Application November 24, 1934, Serial No. 754,670

3 Claims.

This invention relates to new and useful improvements in wall construction.

One object of my invention is to provide a novel method of wall construction, whereby natural stone facing is erected, backed directly with reinforced concrete, forming a monolithic filler or enclosure wall.

A further object of my invention is to build a monolithic wall which will act as a unit under stress insofar as the facing and backing in combination are involved.

Another object of my invention is to provide a novel anchor adapted to engage either two, three or four pieces of stone simultaneously and having shoulders which act in opposite directions where they are embedded in the concrete, that is to say, they resist tension from either the front or back.

A still further object of my invention is to provide an anchor which also acts as a tie or spacer rod while the work is progressing, holding the stone facing in a true plane with the back form and making it unnecessary to erect a form at the front of the wall.

Still another object of my invention is to provide a novel wall anchor which may be used with equal facility with random lengths and heights or regular coursed ashlar.

With the foregoing and other objects in view that will appear as the nature of my invention is better understood, the same consists in the novel features of construction, combination and arrangement of parts illustrated in the accompanying drawings and more particularly pointed out in the appended claims.

In the accompanying drawings, which are for illustrative purposes only and are therefore not drawn to scale:

Figure 1 is a fragmentary face view of a wall constructed in accordance with my invention.

Figure 2 is a back view.

Figure 3 is an enlarged vertical transverse section, taken on line 3-3 of Figure 1.

Figure 4 is an enlarged detail horizontal section, taken on line 44 of Figure 1.

Figure 5 is a fragmentary face view, partly broken away, showing how the anchor head or plate may engage three pieces of stone simultaneously.

Figure 6 is a similar view, showing how the anchor may engage four pieces of stone simultaneously. I

Figure 7 is also a view similar to Figure 5, showing another arrangement of the blocks and anchors.

65 Figure 8 represents enlarged detail views of the anchor per se, one taken at right angles to the other, and Figure 9 is a detail perspective view of the anchor head or plate.

Referring to the drawings for a more particular description of my invention and in which 5. drawings like parts are designated by like reference characters throughout the several views, A designates the building wall, as a whole, and B the anchors, which are disposed horizontally and transversely of the wall. The wall is constructed 10 of stone blocks or pieces I of regular coursed ashlar, or of random lengths and heights, as desired, and the anchor may be used with equal facility with either arrangement. The face of the stone is finished as specified and the back of the stone 1:! is rough sawed.

The anchor is forged from a one half inch round mild steel bar and comprises the front and back sections 2 and 3, respectively. The front and back sections 2 and 3 are joined together at 30 their adjacent exteriorly threaded cylindrical inner ends 4 and 4 by the interiorly threaded cone-shaped coupling sleeve 5. The back sections 3 of the anchors extend through the sheathing 6, vertical studs 1, and walers 8, and are held 35 in place during the erection of the wall by the plates and wedges 9 and II], respectively, or other equivalent means. The front sections 2 of the anchor are permanently embedded in the concrete, while the back sections 3, together with 30 the sheathing, vertical studs, walers and associated parts, are removed after the wall sets or hardens.

In carrying out my invention, the front sections 2 of the anchor, are formed at their outer 35 ends with flat horizontally disposed portions 1 l, which extend into the joints, as I 2, between the super-imposed stone blocks or pieces I and are equipped or provided with rectangular oblong anchor heads or plates l3, which are disposed in 40 vertical edge-wise relation and extend into corresponding co-incident recesses l4 and I5 in the adjacent or meeting edges of the blocks. The recesses l4 and I5 form two pairs of upper and lower shoulders l6 and II, respectively, which 00- 45 act with the anchor heads or plates IS, in holding the stone blocks in place.

In practice, the anchor heads or plates may engage three pieces of stone simultaneously (instead of two) as illustrated in Figure 5 of the 50 drawings, or may engage four pieces of stone simultaneously, as illustrated in Figurefi of the drawings. Figure'l shows stone of random lengths and heights and the anchor engaging two pieces of stone simultaneously.

An important feature of my invention resides in the fact that the front sections 2 of the anchors are, each, formed at the junction of the cylindrical and flat portions, with a pair of tapering shoulders I8 which act in opposite directions where they are embedded in the concrete, that is, resist tension from either the front or back.

From the foregoing description taken in connection with the drawings, it is thought that the construction, operation and advantages of my invention will be readily understood, without requiring a more extended explanation.

Various changes in the form, proportions and minor details of construction may be resorted to without departing from the principles or sacrificing any of the advantages of my invention, as defined in the appended claims.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a wall construction of the character specified, a facing composed of natural super-imposed stone blocks, backed directly with re-inforced concrete, and transverse horizontally disposed anchors used in association with said wall, said anchors comprising straight flat front portions and cylindrical inner end portions and each having a pair of tapering shoulders at the junction of its cylindrical and fiat portions embedded in the concrete and acting in opposite directions to resist tension from either the front or back.

2. In a wall construction of the character specified, a facing consisting of super-imposed stone blocks backed directly with re-inforced concrete and provided in their adjacent or meeting edges with co-incident recesses and transverse horizontally disposed anchors, comprising front sections consisting of straight flat front end portions extending into the joints between the stone 5 7 blocks backed directly with re-inforced concrete and provided in their adjacent or meeting edges with co-incident recesses, and transverse hori- 15 zontally disposed anchors comprising front sections consisting of straight flat front end portions extending into the joints between the stone blocks, and cylindrical inner end portions, each of said front anchor sections having a pair of tapering shoulders at the junction of its front and inner end portions embedded in the concrete and acting in opposite directions to resist tension from either the front or back, anchor heads or plates for holding the stone blocks in place, said anchor heads or plates carried by the outer ends of said fiat front end portions and disposed in edge-wise relation in said co-incidentrecesses, and back sections removably connected with the front sections of the anchors and adapted to extend through the sheathing, studs, walers and associated parts during the construction of the wall.
