WILLIAM 0. ISAACSON, OF CHICAGO, ILLINOIS.

This invention relates to anchors for fastening bucks and the like into place and with regard to certain more specific features, to means for fastening construction members to masonry.

Among' the several obj ects of the invention may be noted theprovision of a one-piece anchor for fastening wooden or like members to masonry and the like, said anchor being adapted to be accommodated to various widths of the wooden members; the provision of an anchor of the class described adapted to be applied to various types of masonry; the provision of an anchor adapted to be stamped from strips of sheet material with substantially no waste; the provision of an anchor of the class described which is rigid in its application, yet which is adapt-ed to be easily applied because of its iiexibility before application; and the pro visionkof a device of the class described which is economical of manufacture. Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly comprises the elements and combination of elements, features of construction, and arrangements of parts which will be exemplified in the Struc-r ture hereinafter described, and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings, in'which is illustrated one of various possible embodiments of the invention,

Fig. 1 is a plan View of the anchor applied to one form of masonry;

Fig. 2 is a side elevation of Fig. 1;

Fig. 3 is a vplan view showing the manner in which the anchors are cut from a strip of sheet material; and

Fig. 4 is a planview showing a modified application of the anchor to another form of the masonry.

Corresponding reference characters indicate corresponding parts throughout the several views of the drawings.

Referring now more particularly to Fig. 1, there is illustrated at numeral 1 a pair of legs joined together by means of a bendable or hinge portion 3. The hinge port-ion 3 is formed substantially at right angles to the legs 1 and is formed as a pointed spur (see alsoFig. 3). The exact shape is immaterial, except thatthe spur should be adapted to be driven into a more or less chalky material such as gypsum. The legs 1 are stiffened by ANCHOR.

suitable ridge portions 5 bentinto the material thereof. f

At the forward end of each of the pair of legs 1 is formed an extension arm 7 which in the application of the anchor, is positioned substantially at right angles to the plane of the said legs 1. The arms 7 are provided with suitable holes or openings for driving fasteners therethrough, such as nails 9 adapted to be driven into the buck 11 or the like. Screws or other devices may be used as fasteners.

The application of the anchor is evident from Fig. 1. The masonry member 13 into which the anchor is driven by means of the spur 3 is composed of a chalky substance such as pyrolite or the like. Before application, the legs 1 of the anchor are parallel and `juxtaposed and the arms 7 are not bent angularly. Application is made by pulling the legs 1 apart, in scissor fashion until the arms 7 are properly positioned forv the particular thickness of wall to whichthe anchor is being applied. The spur is thus bent and automatically stiffened. The anchor is then positioned longitudinallyr along the wall until the arms 7 are properly positioned for bending around the buck 11. At this stage the spur 3 is driven down into the chalky substance by means of'a. hammer or like tool. The ends of the arms 7 are then conformed to the shape of the buck 11 and the fasteners 9 driven home. The construction is then ready for the application of the next member 13, the requisite plaster being placed over the anchor itself.

The' manufacturing operations required for making the anchor are illustrated in Fig. 3. A strip ofmaterial of proper'width is `fed through a punch press which outlines and cuts the shape of the anchor in a single flat sheet. The holes 8 for inserting the nails 9 may or may not be punched at the same blow. A recess 15 is cut, separating the legs 1. It may be seen from Fig. l3, that the shapes of the successive anchors are nested, whereby material is conserved.

After the `outline of the anchor is cut, the holes 8 may be punched, if they have not already been punched when the outline was first formed. Crimps 17 are next put in for the purpose of permitting easy shaping of the anchor in the field or elsewhere. At this stage the ridge portions 5 are also put in along the lines 19.

It is evident that the anchor mayr be lli) shipped fiat or shipped with the proper bending operations having been performed at the crimped lines 17. The anchorsare always shipped with the ridge portions il formed therein, whether they are flat or bent into shape. i

Fig. 4 shows the application of the anchor to a hollow tile construction, wherein the spur 3 cannot be driven directly into the hard vitrilied material comprising the tile. In this case the anchor is bent as hereinbefore described, but the spur 3 takes up a position within one of the recesses of 'the tile instead of being driven into the A ridge 23 automatically formed therein, which ridge stiffens the spur 3 for the driving' operation to be performed thereon 1n applying lthe member to the masonry member 13.

Another advantage of the invention comprises the fact that after the anchor has been applied, the legs 5 are in a slanting position with respect to the wall and hence act as struts to prevent movement of the buck at right angles to the wall. Hence the bracing effect of this anchor is much greater than that of most anchors.

In view of the above, it will be seen that thek several objects of the invention are achieved and other advantageous results attained.

Asmany changes could be made in carrying out the above constructions without departing from the scope of the invention. it .is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

I claim:

l. An anchor comprising a pair of legs joined by means of a bend.able,portion substantially at right angles thereto, said bendable portion forming a spur and extension arms associated with said legs adapted to be joined to a member to be fastened.

2. An anchor comprising a pair of legs formed substantially in a horizontal plane and joined by means of a bendable portion substantially at right angles thereto. said bendable portion forming a spur adapted. to be driven into masonry and extension arms associated with said legs, said arms and legs being adapted to be manually spread for accommodation to any thickness of wall,

whereby said spur is put into condition to be driven.

3. An anchor comprising a pair of legs formed substantially in a horizontal plane and joined by means of a bendable portion substantially at right .angles thereto, said bendable portion forming a spur adapted to be driven into masonry, and extension arms associated with said legs, said arms and legs being adapted to bemmanually spread for accommodation to any thickness of wall, whereby said spur is put into condition to be driven. said arms being formed substantially at right angles to said legs. p

4. An anchor comprising a pair of legs formed substantially in a horizontal plane and joined by means of a bendable portion at right angles thereto, said bendable portion forming a spur adapted to be ydriven into masonry and extension arms associated with said legs, said arms and legs being adapted to manually spread for accommodation to any thickness of wall, whereby said spur is put into condition to be driven, said arms being formed substantially at right angles to said legs and adapted to be applied to a member which is to be held.
