This invention relates to anchors, and with regard to certain more specific features, to anchors for masonry, tile and like walls.

Among the several objects of the invention may be noted the provision of an improved anchor for fastening door and Window bucks and the like to tile walls and the like; the provision of an anchor of the class described which requires for its application no co-operation between carpenters; tile-setters, plasterers and/ or others; the provision of a. device of the class described which may he shipped as a single unit and separated for application and use at the field of operation; the provision of an anchor of the class described which accommodates conduits and the like in the walls to which attachment is made; and the provision of a device of the class described which is exceedingly simple in form and which can be easily manufac tui-ed. Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly comprises the elements and combinations of elements, features of construction, and arrangements of parts which will be exemplified. in the structure 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 e1nbodiments of the invention,

Fig. 1 is a plan view of an anchor unit showing the anchor piece and a bracket in one piece before being separated;

F ig. 2 is a perspective view showing how a bracket is detached and nailed to a buck so as to hold the separated anchor portion per se, more or less flat against said buck;

TEig. 8 is a perspective view showing the bracket nailed to a buck and the anchor applied to a section of tile wal'l; and

Fig. 4 is an enlarged detail side elevation showing the sprung position of parts of Fig. 3.

Similar reference characters indicate corresponding parts throughout the severa-l views of the drawings.

Referring now more particularly to Fig. 1; there is illustrated at numeral 1 a body por- Serial No. 413,711.

tion of the anchor having embossed opening 3, the latter serving holding purposes.

Extending longitudinally and in a parallel direction, is a pair of anchor legs 5 which are joined to said body 1. The legs 5 are corrugated in biased fashion, in order to provide a gripping effect in oints of mortar; cement or the like into which they are later to be embedded. The biased formation of the corru gation 7 serves to stiften the legs 5 longitudinally and at the same time provide increased holding surface between said legs and the mortar.

On the edge of the body 1 which is opposite to that from which extend the legs 5 is located a hinging slot 9, the purpose of which will be made clear.

In Fig. 1 is shown lying between the legs 5, a bracket portion 11, which is stamped to shape from one piece at the same time that the body 1 and its attachments are stamped. The same die preferably does all of the stamping7 and during the operation relieves the bracket 11 from the body 1 at all points except at a plurality of points or junctures 13. These unctures 13 permit the transportation of the body 1 and the bracket 11 as a unit but at th-e same time permit of knocking or bending the bracket 11 from between the legs 5 at the field of operation. This removing operation may be accomplished by the carpenter who applies these anchors to the bucks.

In form, the bracket 11 will be seen to comprise supports 15 having suitable openings therethrough whereby they are adapted to be nailed to the side of a buck 17 or the like. Between the supports 15 is a bridge portion 19 having strengthening ridges 21 formed therein. After application of the bracket 11 to the buck 17 it will effect a bridge thereon.

The width of the slot 9 is slightly greater than that of the bridge-like bracket 11, so that after the bracket is knocked loose from the body 1, said bracket may be inserted into the slot 9. Theslot 9 is provided with suitable bights 9.3 for accommodating passage of the ridges 21 of the bracket 11.

It will be seen from the above that the portion 25 of the body 1 which is on the outside of the slot 9 forms what may be termed a hinge strip 25. As illustrated in Figs. 2, 3 and 4;, said hinge strip 25 is slightly bowed. Also, the etiective width ot this hinge strip 25 is slightly greater than the elevation of the bridging portion of the bracket 11 from the buck 17. This feature has been exaggerated in Fig. 4, for clarity. rThe dotted lines. in said Fig. 1 represent an unsprung position of the bridge. l

The operation of the device is as follows:

The carpenter receives the anchoring device in the condition shown in Fig. 1, namely7 with the bra-cket 11 held to the body 1 and its appendages by the oining portion or breakable junctions 13. YThe carpenter separates the bracke-t 11 from the remainder of the device. This is best done by twisting the brid portion 11 about a line drawn through the j unctures 13.

Next, the bracket 11 is threaded through the opening 9. The bracket 11 is then nailed to: the side of the buck or the like as illustrated in Fig. 2. It will be understood that the body 1 may be moved down so as to per mit nailing of the support 15 which is shown in Fig. 2 as covered by the body 1.

The buck 17 is then brought into position next to the wall 27 to which it is to be astened. The strengthening ridges 21 may be aligned with the grooves 29 which ordinarily appear in tile anchors of the class shown.

Thereafter the body portion 1, which normally remains in the F ig. 2 position after the fastening of the bracket 11, is hinged downu wardly- Inasmuch as effective width of the hinge strip 25 is slightly wider than the elevation of the bridge portion of the bracket 11, it exerts springing action on the bracket 11. The bow of the strip 25 stiiens it so that it will effect the action described. Thus there is provided a relatively rigid or semi-A rigid connection between the body 1 and the bracket 11. For clarity this action is exaggerated in Fig. l.

It will be seen that the elevation is optional at which the body 1 is hinged down and caused to react and spring the bracket 11 so as to extend more or less rigidly. Thus, varying elevations of tile joints may be accommodated.

lVith the anchor in the position shown in Fig. 3, it will be seen that the legs 5 lie along the walls 31 of the tile and that said legs 5 will accommodate therebetween any conduit or the like 33 which may be located within the walls 27. It is also clear that no portion ot the anchor extends outwardly from the wall.

Among the advantages of the invention are the following:

The anchors may be nailed-to the bucks when the bricks are made up and the carpenter needs pay no more attention to see that the: elevation of the anchor fits the wall joint elevation. He knows that the anchor units are to be applied within a certain geireral range ot positions, but he needs not effect careful measurement, because of the vertical displacement of the body 1 permitted by the bracket 11.

After the carpenter has finished applying the anchor to the bucks, it remains approximately in the Fig. 2 position. This is because the hinge strip 25 is wider than the spacing under the bridge of the bracket 11, the body 1 will not fall angular-ly any deleterious distance away from the side of the buck 17.

W'hen the tile setter received the buck 17 for placement and attachment to the wall 27, lie need merely hinge down the body 1 after having made the suitable adjustment for elevation of same, so that position of the body 1 matches the given elevation of the tile joints. Thereafter, the tile setter applies mortar to the tile joints and sets up the next tier of tile. This operation does not interfere to any practical extent with his normal operations in building the wall.

Vhen the plasterer comes to apply a plasu ter facing to the wall 27, there is no projection or other interfering extension. Hence, the plasterer may provide a smooth linish directly up against the buck or jarnb 17.

It will be understood that for ordinary wood door bucks about six anchors are required, three to each side of the buck. The anchors are attached to the bucks before the bucks are set up. It is preferable that the anchors be spaced about twenty-five inches apart to provide an approximate multiple o'f tile widths. It will be understood that this multiple may be made to suit any other blocks which are being used to build the wall, such as gypsum or masonry. Common nails are preferable for fastening the brackets 11, although screws may be used. The nails may be clinched over if they project through the buck.

It will be seen that by arranging the bracket 11 of the anchor between the legs 5 of the anchoring portion at the time of stamping, that a great saving in materials is effected.

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

As many changes could be made in carrying out the above constructions without deiarting trom 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 illl lustrative and not in a limiting sense.
