BUCK ANCHOR.

Application filed November 28, 1823. Serial No. 677,405.

T 0 all 107107 it may concern:

Be it known that we, TAMIS C. SCHENK and PETER GOl IBERT, citizens of the United States, and residents of Bridgcville and Pittsburgh, respectively, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Buck Anchors, of which the following is a specification.

This invention relates to building construction, and particularly to buck anchors for rigidly securing door frames to walls formed of hollow blocks or tiles.

One of the most common methods of at taching the side members or so-called bucks of door frames to partitions built up of terra-cottablocks or tiles is to drive nails into or through the buclts so as to provide projections which may be either embedded in the cement between the superposed courses of the blocks or tiles, or which in some instances are embedded in the blocks themselves. hen the former scheme is used, the nails are generally driven part-way into the faces thereof adjacent the blocks so that their projecting heads may extend between the courses to be, embedded as described, whereas when the latter scheme is adopted the nails are driven directly through the bucks so as to enter the cement forming the bonding layer or directly into the body of the blocks if the same are of such nature as to permit this practice. Both of these methods are open to various objections not only because of the difiiculties attending i11 spe'ction but because the nails readily loosed, jar out, and loosen their anchoring or bind ing effect. Furthermore, the subsequent nailing of the plaster supporting means, the jamb, and the trims tends to destroy or weaken the attached parts. It is also well known that such methods are entirely unsuited for attaching bucks close to and spaced from partition walls under which circumstances the buck can not be supported directly from the partition wall, and this'is particularly noticeable when it is desired to so position the-bucks and at the same time provide a full trim.

The object of this invention is to provide an extremely simple, inexpensive and easily applied buck anchor which will overcome the disadvantages above noted, which will positively and firmly lock the buck directly to the partition wall and hold'it against both transverse and longitudinal movement relative thereto.

It is a special object to provide a buck anchor of the character referred to which is adapted for use under avariety of conditions and by which bucks may be readily and directly anchored to the partition wall regardless whether the buck is positioned at the end or side of the partition, or whether it is disposed in contact therewith or spaced therefrom.

It is also a special object to provide a buck anchor which is adapted to support the buck at any desired angle relative to the partition wall to which it is fixed, and which engages the tiles of the wall in such fashion as to obviate the danger of either transverse or longitudinal movement of the buck.

These and other objects will more fully appear when taken in conjunction with the following description and appended claims.

In the accompanying drawings, Fig. 1 is a fragmentary view, in perspective, illustrating the use of the invention for supporting a buck at the end of the partition wall and in alignment therewith, the layer or course of tiles immediately above the anchor being removed so as to clearly show the mode of engagement between the anchor and the walls of the tile; Fig. 2 a similar view illustrating the method of supporting the buck at the side of the partition wall contiguous the end thereof; Fig.3 a similar view showing the method of usingthe invention for supporting the buck at the side of the partition wall, at right angles thereto, and spaced there from; Fig. 4 a view corresponding to Fig. 3 in which the buck is disposed at an angle to the partition wall; and Fig. 5 an enlarged detailed perspective view of the buck anchor removed.

' The improved buck anchor is preferablywith suitable openings 4 adapted to receive nails or screws tor attaching the buck to the anchor. These fingers are comparatively wide at their point of connection with the body for the purpose of increasing the strength of the anchor, but gradually decrease in size towards their tips or extremities. The extremities of the fingers are bent (hiwnwardly as shown at 5, these extremities lying in a plane substantially parallel to that occupied by the body 1.

The distance between the side of the body and the inner surface of the extremities corresponds to the wall thickness of the hollow blocks or tiles with which the anchor is to be used, and the distance between the adjacent extremities 5 corresponds to the thickness of the internal transverse webs joining the side walls of the tiles.

In all of the figures of the drawings, the hollow blocks or tiles are indicated at 6 and for simplicity merely two superposed layers forming the partition wall are illustrated. The extremities 5 are spaced from the body a distance corresponding to the thickness of the side wall 6, and the tips of adjacent fingers are likewise spaced a distance corresponding to the thickness of the transverse webs 6, as described. Due to this construe tion when the anchor o ieratively engaged with the walls of the tile. with the lingers 2 interposed between the courses of blocks, the side walls 6 are snugly embraced between the body 1 and the bent extremities 5 so as to avoid relative lateral movement of the anchor, and similarly when the anchor is positioned. so that the transverse wall 6" falls between two adjacent fingers, the anchor is positively locked against longitudinal movement.

In operation. the anchor described lends itself to a variety of uses under varying conditions, in each instance, however, supporting the buck directh from the partition wall with which it is associated. and exerting the stresses and strains due to the attachment of the buck in a aight line pull.

In Fig. l. the anchor is employed for se curing the buck 7 at the end of the wall and in alignment therewith, the buck being interposed between the extensions 3 of a pair of anchors attached to the opposite side walls of the tiles. and the anchors are fast ened to the buck by nails or screws passed through the openings It is noted that due to the snug fit ot' the side walls 6 between the body 1 and the extremities 5 all danger of lateral movement is eliminated, and due to the engagement of the fingers with the web 6. the buck is positively locked against movement away from the end of the wall.

The anchors are preferably used in pairs, as just described. in which case the fingers of the opposed anchors extend in opposite directions from the bodies thereof, however, in many instances the employment of but a single anchor is necessary.

The method of using the improved anchor for securing a buck at the side of the partition wall. immediately adjacent one end thereof is illustrated in. Fig. 2, in which the buck is shown at 7. In this case, the body of one anchor is bent as at 8 so as to abut the side of the buck, while the opposed anchor is bent at 8 so as to engage the corner of the end tile. Vith this arrangement the fingers and bodies of both anchors separately and conjointly assistin preventing both transverse and longitudinal movement of the buck.

For the purpose of supporting the buck intern'iediate the length of the wall but spaced therefrom, and at right angles thereto, the method shown in Fig. 3 is employed, in which figure the buck is indicated at 7". In order to space the buck from. the partition wall a slab 9 of suitable size is interposed between the wall and buck. The bodies of the anchors are bent at 10, 10, with the fingers engaging the side walls of both the tile 6 and the slab 9. henever one of the fingers falls so as to overlie the abutting end walls 6 of contacting tiles, as illustrated in this figure, the said finger ,is flattened so that its extremity 5 projects in the same plane as the finger, in the manner indicated at 11, The fingers of both anchors assist in directly supporting the buck from the partition wall and prevent movement of the buck away from the wall, while the pair of fingers straddling the web 6 preclude movement of the buck longitudinally of the wall.

If it is desirable to locate the buck spaced at the side of the partition wall and disposed at an angle thereto, the same may be accompllSllQd by interposing a. slab 9 as illustrated in Fig. i. The buck 7 is in this instance directly supported from the partition wall in a manner similar to that pointed out in connection with Fig. 3, the several parts cooperating in an analogous way.

Both of the methods shown in Figs. 3 and are particularly adapted for supporting bucks in closely spaced relation to the partition wall while at the same time throwing the entire strains directly upon the wall in a straight line pull, and permitting full trim to be used in connection with the bucks.

It is thus seen that the invention provides an extremely simple and inexpensive form of buck anchor which is capable of directly supporting the buck from the wall to which the anchor is attached, one which lends itself to a variety of uses, being adapted to support the buck directly from the wall regardless whether it is located at the side, at the end, in contact or spaced Ill) therefrom, and one which positively locks the supported buck against both transverse and longitudinal movement with respect to its supporting wall.
