A threaded anchor stud carries an internally threaded collar which is attached to the flat plate that extends between joints in adjacent courses of stone. The flat plate may carry angular portions at the end which extend into kerfs formed in the respective adjacent stones. The end of the stud is inserted into a hole in the face of the wall and secured therein by mortar, adhesive and the like and thereafter the collar with the plate may be screwed in or out relative to the face of the wall to adjust the stone anchor to the proper extension thereby eliminating altogether the use of a variety of different sizes of stone anchors. In one form the plate is split on the end and turned in opposite directions whereas in another form a pin is secured perpendicularly to the plate.

' AffoR/v y STONE ANCHOR BACKGROUND OF THE INVENTION 1. Field of the Invention Stone anchors used in the construction field for anchoring veneers such as sections of stone to the wall.
2. Description of the Prior Art US. Pat. Nos. 938,662; 2,298,743; 2,663,735; 3,178,026; 3,450,427; 3,471,183 may be considered relevant prior art. However, none of these patents disclose an adjustable stone anchor. Significant prior art might be the information listed in the Marble Institute of America, Inc. AMERICAN STANDARD SPECIFI- CATIONS FOR THIN EXTERIOR MARBLE VE- NEER, ETC, copyrighted by the Marble Institute of America in 1961, and also the Building Stonelnsfllte STONE 1968 69 CA I A IJO G w'lficli contains a Glossary of Terms stating that similar types of anchors of flat stock are known as straps, cramps, dove tails and dowel, strap and dowel and two-way anchors and discloses a number of forms of these none of which are stone anchors that are adjustable. The stone anchors disclosed in the above material are fixed and not adjustable.
SUMMARY OF THE INVENTION By having the anchor member which is inserted and fixed into the wall adjustably supporting the part of the anchor which fits into the joint between the stone, it is possible after installation of the fixed stone member to adjust the movable portion inwardly or outwardlythereby eliminating the cost of carrying many different sizes of stone anchors and also the labor consumption on the job of selecting the proper sizes. In addition, it is much easier to obtain the proper size because of the flexibility of adjustment.
' BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a cross-sectional view of a concrete wall with the stone anchor of FIG. 3 installed therein.
, FIG. 2 is a perspective view of an adjustable stoneanchor of the present invention with a vertical pin.
FIG. 3 is a perspective view of another form of the present adjustable anchor utilizing turned ends.
DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1 there is shown in cross-section a typical installation of a bottom course of marble and a portion of the next adjacent course. A concrete wall of a building designated generally by reference numeral may be the usual poured construction in a multi-story building. Such construction 10 usually involves an irregular concrete face 12 which is veneered by decorative stone shown in the drawing as two courses 14 and 16. The bottom course 14 may be supported in conventional manner on a steel support angle 18 which is attached to the surface 12 of the building 10 in any conventional manner and usually has a vertical lugor pin 20 on the ledge 22 thereof extending into a kerf 22 in the stone 14.
The adjustable stone anchor is designated generally by reference numeral 26 and comprises a first member 28 which is usually a fixed member and is presently in the form of a threaded shaft having a head 30 like a nail thereon, and a threaded portion 32 extending a substantial distance along the shaft. A portion of the shaft 28 is inserted in a hole 34 which has been drilled into the wall of the building 10 and secured in place by any suitable adhesive 36 such as mortar or cement such as epoxy. The shaft 28 is arranged generally perpendicular to the wall 12, extends outwardly therefrom and carries a threaded collar 40 in a block which is internally threaded or threadedly match with the threads 32 on shaft 28 and which collar 40 is integrally formed with or attached, as by welding, to a flat plate member 44 which extends between the joint 46 of the adjacent courses of stone l4, 16. Plate 44 is split on the end and bent in opposite directions to form substantially perpendicular ends 50, 52 each of which extends into a respective kerf 54, 56 formed in a respective stone 14, 16.. In some anchors the shaft member 28 is a flat piece of V-shaped metal.
In the installation after the anchor 26 has been firmly fixed in the wall of the building 10 by the adhesive 36 then the plate 44 manually may be adjusted inwardly or outwardly with respect to the wall by rotating the same to cause the collar 40 to screw inwardly or outwardly on the threaded portion 32 whereby only one stone anchor size is required for the job. Thus, the workman can maintain the vertical alignment and installation of the stone courses 14, 16 regardless of the irregularity of the face 12 of the concrete of the building 10, and
without searching for, altering or selecting different sizes of anchors.
In the embodiment shown in FIG. 2, the construction of the stone anchor is substantially the same except for the end portion wherein the split ends and plates 50, 52 have been replaced. This stone anchor in FIG. 2 is designated generally by reference numeral and comprises the same construction of member 72 with head 74 and threaded portion 76 as in the previous construction as well as the collar 78 which has the flat plate 80 attached thereto. In lieu of the flat plates 50, 52 of the previous embodiment there is a perpendicular pin 82 extending through the plate 80 and attached thereto either by integral fabrication or by welding or some other means of attachment so that there are in effect two pins 84, 86 one on each side of plate 80 and each pin 84, 86 extends into a respective kerf 54, 56 on the courses of stone 14, 16 in the same manner as the plates 50, 52 of the previous embodiment. The adjustment of the stone anchor 70 is the same.
While I have shown and described two embodiments of my stone anchor this is by way of illustration only since there are various other forms of the present invention because various alterations, changes, deviations, amendments, omissions, additions, changes and departures may be made in the form shown without departing from the scope of my invention as defined by proper interpretation of the appended claims.
I. In an adjustable stone anchor for anchoring stone to the face of a building and the like:
a. a first, elongated stone anchor member having one end for insertion and fixed placement in the face of the building by inserting and anchoring the end in a hole in the building, said first anchor member extending outwardly from the building and being fixed against movement,
b. a second elongated stone anchor member mounted on and extending from the external end of the first member opposite from the end anchored to the building and as an extension of said first member, and
c. adjustment means between said first and second stone anchor members consisting of an internally threaded portion on one of said first and second 5 stone anchor member and an externally threaded portion on the other of said first and second stone anchor members, said adjustment being effected to move said second stone anchor member inwardly or outwardly selectively on said external end of 0 said first member solely by relative rotation between said first and second stone anchor members without tools by setting the first stone'anchor member in place in the building and then rotating the second stone anchor member thereon to adjust the amount of extension of the second stone anchor member on the first stone anchor member.
2. The device claimed in claim 1, wherein there is a member extending from each side of said second stone anchor member to be inserted into kerfs in said stone.
3. The device claimed in claim 1, wherein: said second stone anchor member is separated on the end and said members extending from each side of said stone anchor member extend in opposite directions into said stone.
4. The device claimed in claim 3, wherein said second elongated stone anchor member is a plate and there is an elongated member extending from one side of said plate and an elongated member extending from the other side thereof.
5. The device in claim 1, wherein: said first elongated stone anchor member has an enlarged head on one end thereof.
6. The device in claim 5, wherein:
said second member is a flat plate.
