The object of my invention is to provide a buck anchor of simple, durableand inexpensive construction.

More particularly, it' is my object to provide a buck anchor yso constructed and arranged that it can be quickly and easily mounted' on the buck in position for forming ank attachment.: s Y c Still another purpose is Vto provide a buck anchor so constructed as toaiiord a maximum'anchorage j With these and other objects in View, my invention consists lin thepconstruction, arrangement and combinationsof the various 15. parts of my buck anchor, whereby the objects contemplated ,are attained,I as hereinafter more'fully set forth, pointed out in my claims, and illustrated yin the accompanying.draw ings, in which: n

Figure 8 is a perspective view illustrating a slightly modified arm on the buck anchor Y of the type shown in 'Figure 3. In buildings where clay or gypsum tile partitions or walls are used, it is the V'practice to set roughk wooden bucks or Vframes for openings.A YThese bucks are usually made of ""5 rlumber from one .to two inches thick and of the width of the unplastered wall. l After the' wall is. plastered, 'the finished vdoor or window frame is nailed to the buck.

The clay or gypsum tile are laid up in layers or courses, which are usually twelve inches c in llileight and of the width of the unplastered wak Many methods are fused to hold these bucks in place. The most common one is to drive two spikes into the buckat the top of each layer of tile before laying the next course, with about three-fourths of the lengths of the spikes flying along the top side of the tile which has been=laid. Y l `This method is unsatisfactory because after two vor three courses of tile have been put in place then when thespikes are-driven into the upper portions of the buck, the vspikes have already been drivenginto the lower parts and anchored betweenthe rlower courses or jarred loose inthe mortar beds. As result, the rigid anchorage for the buck is destroyed and the buck is notheld properly in place.-

Other methods are used, some of which are verly expensive.: One objection to most of these methods larises from the fact that vthey involve drivingthe anchor into theface of the buck adjacent to the wall. e This sprin s the buck," thus breakingloose the lower anc oring members from their anchorage.

My improved buck is designed to obviate these difficulties. f

In Figure 4,1 have shown a plan view of f one of my buck anchors, as it comes from the factory. Y Y

The ybuck anchor as it comes from the factory comprises a connecting member indicated generally at l0, designed to rest horizontally above a course of tile, and preferiably havingk a central down-turned portionk 10a, which ymay rest upon a flat-walled tile or project into'the opening in certain kinds of tile. Y The buckv anchor is made of resilient material and has extending forwardly and `diverging from the ends of themember the portions 12. vlllxtending ,forwardly and converging toward each other from the ends of the members 12 are the members 14', which have at what may-be called their outer Sends the parts 16, inclined outwardly and terminating inthe. backwardly turned, pointed members 18.

The membersl and 18 form a slight acute angle with relation to each other.`

In the practical use of my buck anchor, it may be installed in two different ways.

When used as illustrated for instance in Figure 1, the courses are regularly laid and at the proper time ust above the last course laid the buck anchor is placed in position for engaging the buck, which has been placed in proper position. The buck is indicated at 20. The tile of the various courses are indicated at 22. The buck anchor arms or members 14 are sprung so as to incline across each other as shown in Figure 3. They are sprung to the position shown by dotted lines in Figure 2, so that the pointed members 18 will stand substantially at right angles to the sidefaces of the buck 2O (see. Figure 2). The pointed members 18 are then driven into the buck, and` it ywill be seen that the parts are so constructed and arranged that the members18. will not drive straight into the buck, but will he inclined slightly toward each other and toward thc wall.

The members 16 lie parallel with the side faces of the buck and in the installation as shown in Figure 1, they are pounded until they are driven into the buck to lie flush with the faces thereof.

The parts are so arranged that when the anchor isinstalle'd on the buck, the portions 12 lie on top of the tile and adjacent to the outer edges thereof. This is of some importance for by such an arrangement ay maX- imum anchorage isr afforded.

It is practically certain that there will be mortar or tile as at 24 inside the members12.

On account of the resiliency of the buck anchor, it can be sprung and gripped on the buck at the proper places, and will then by its own resiliency'7 grip the buck and remain inv place untill the workman is ready to drive the pointed members18 into the buck.

In Figure 5, I have shown a slightly different mode of installation. When this method is used, the anchors are installed on the buck at approximately the proper heights, and the pointed members 18 are driven into the buck.

Because of the fact that the buck isset up on rough concrete slab iioors, in ordinary practice it is very dilicult to mount the buck anchors at exactly the right heights, but if the pointed members 18 aredriven in and the. members. 16 are not pounded into. the buckit will be seen that as the courses are laid. up, the members 16 canbe inclined from the. horizontal as illustrated for instance at A in Figure, and ywhen the next course of tile vis laid,the' tile will bend the. buck; anchor at the joints between the members or Vportions16 and 14 as at B in Figure 5, and thus the buck anchors which have been installed on the bucks before the courses were laid can be readilyfadj usted to lit between the courses.

This is oftentimes of considerable im portance and convenience in anchoring the bucks in place.

In Figure 8, I have shown a portion of a buck anchor with the member 16 similar to that already described terminating in an eye 26 instead of the pointed member 18. A headed nail or the like 28 then forms the means by which the buck anchor is fastened tothe buck and becomes part of the anchor.

In Figure 6, I have shown another modification of my buck anchor having the

parts

12, 14, 16 and 18 similar to those already described.v Instead of the part 10, there is provided a substantially horizontal part forming a connecting member 28, the central part of which forms a loop 30 which may be horizontal and may bebent downwardly so as to iit in an opening in a tile.

In Figure 7, I have shown still another modification of my buck anchor intended for use where more anchorage is necessary.

The form of buck anchor shown in Figure 7 has instead of the member l0 a straight cross connecting member 32 extending away from which instead of the member 12 is a horizontally luted portion 34, from ywhich extend the portions 14a, similar to the portions 14. From the portions 14a, there extend the flutcd portions 36 having at what may be called their forward ends the straight portions 37, the forward ends of which are bent back on each other as at 38, and are then inclined away toy form pointed portions 18 similar to those already described.

A buck anchor of the type described herein has a number of important advantages.

In the first place, it can be mounted on the buck by the workman, whosimply grasps the anchor in his hand and crosses the member 14, changing the parts from their positions shown in Figure 4 to their positions shown in Figure 3. This makes a very convenient manner of mounting the anchors on the bucks. It also forms a sort of loop at what may be called the rear or inner end of the anchor, which gives vstrong anchorage in a bed of mortar or flat crossed-face tile.

The arrangement of the

parts

16 and 18 at acute anglesy to each other has a number of advantages.

When the `members 16 are sprung apart enough to permit the buck to be received between the members 18, the members 18 then stand nearly at right angles to the buck as shown by dotted lilies in Figure 2. Yet when they are driven in, they are inclined toward the wall slightly, which is a desirable result to'be attained.

Someof the advantages of my anchor have already been explained. They illustrate one of its important general advantages, to-wit, its adaptability for use, convenience with which it maybe installed, and its adaptability for different kinds of operations.

Of course, one'of the great advantages is that it can be fastened to the buck either during the laying-ofthe courses or before the courses are laid. If it is fastened and placed as the courses are laid up, the driving of the 5 members 18 into the buck at the sides thereof instead of into the face next to the wall reduces the-tendency to'spring the buck and very largely eliminates the tendency to pull out or break loose the lower buck anchors already anchored in the wall.v

Using the buck anchorsfas shown inFigure 5, any pounding `which might tend to loosen them in the wall is wholly eliminated, I claim as my invention: 1. kA". buck anchor, comprising an inner cross member, first portions inclined away from the endsy thereof and away from each other, second portions inclined away from the ends of said first portions and toward each other, third portions inclined away from the ends of said second portions and from each other, and pointed members turned back from the ends of said third portions wherebysaid second portions may be sprung across each other and said pointed members may be caused to engage between them a buck, said anchor being of resilient material and constrainingsaid pointed members to enter the buck. l 2.
