WALL BRACKET.

Application filed December 16, 1920. Serial No. 431,14'10.

T0 all whom z't may concern.'

Be it known that we JAMEs R. KEARNEY, and HARRY L. JoHNsoN, citizens of the United States, residing at Kansas City, Missouri, have invented a certain new and useful Improvement in Wall Brackets, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a detail view of our improved wall bracket.

Figure 1 is a detailview of a modified form of wedge.

Figure 2 is a sectional view showing the same in position. r i

This invention relates to a new and useful improvement in wall brackets, especiallycde- Signed for use with brick or stone walls the object being to construct a device of the character described which is simple and cheap and one which can be readily and quickly applied so that when in position it can not be easily displaced or removed;

The bracket is intended to support electric insulators or electrical appliances, but itis` obvious that it can be used for other purposes; and in this connection it is apparent that th projecting end of the bracket may be shaped differently from that shown in the drawing so that it is more readlly adapted for various devices which it is intended to support.

In the drawings, 1 and 2 indicate flexible tongues which are preferably more widely separated at their free ends than toward their` heel portions. These tongues may be pointed at their ends, but we prefer to make them slightly blunt, and by use of a roughening tool provide their outer faces. near their ends with burrs or holdingprojections 3. The tongues are scored or cut, as at 4, so as to form flaring wings 5 which are bent upwardly and forwardly, said wings being yielding' to such an extent that when they enter between two bricks or pieces of stone` as shown in Figure 2, they will engage the contiguous surfaces thereof and assist in preventing the bracket from being withdrawn, and also tend to prevent vertical and lateral movement of th wedge near the outer edge or face of the brick.

Abutting tongues 6 are also struck up from the body portion of the bracket and near its outer end, these abutting tongues extending in opposite directions so that they will engage the outer faces of the bricks or stones on each side of the crevice in which the bracket is driven. The head 'portion of the bracket, or that portion which extends outwardly beyond'the faces of the bricks or stones and which is used to support a device or appliance (not shown) is preferably formed by folding the blank, from which the bracket is made, upon itself; 'This head portion 7, shown in the drawings as a shelf, may be provided with an opening or openings 8 for the purpose 'of attaching a sup- H ported object thereon. 2

In practice, the mortar between' the stones or bricks is first removed to the required dep'th. When a proper opening is made, a wedge 9 is placed between the free ends of the tongues l and the tongues introduced into the openingand driven home. The wedge in striking the bottom of the opening formed to receive it is arrested and further driving of the bracket inwardly over the wedge will cause the tongues to spread apart, as shown in Figure 2, and their roughened outer faces to engagethe mortar, stones or bricks with which they come in contact. 'It is always necessary that the wedge reach the bottom of the opening made to receive the bracket. VVlth ,the wedge inserted between the tongues of a bracket, the hammer blows on the outer end of the bracket will act on the wedge and draw the same in between the tongues as the bracket is being driven home. The final driving movement of the 'bracket will force the flexible flaring wings inwardly,'as shown in Figure 2, and this will also assist in preventing withdrawal ofthe bracket and vertical and lateral movement thereof. The opening for the bracket is preferably made deep enough so` that the abutting tongues can be brought into engagement with the faces of the bricks or stones between which the bracket is driven. I

It is obvious that the bracket can be arranged either in a Vertical or horizontal po- Ili) bracket. is not ofsufficient size to permit the bracket to be driven home so that its abutments Will engage the outer face of the wall, thentheoperator can shorten the Wedge by breaking off one or more sections from its larger end.

In Figure l we have shown a wedge produced by pressing or sfamping corrugations 10 in the wedge, these corrugations ing-,reasing in depth from the flat point of the Wed e to the opposite end'thereof. If it is found that the opening made to receive the tongues of the bracket' is not .of sufiicient size to permit the bracket to be driven home, so that" its abu'tinents Will engage the outer face. of thewall, then the operator can thin the Wedge 10 by hammering out the corrugations.

ALW aIl bracketz formed of a single flat piecexof metal bent .uponitseli at its outer end and having: fiat: mwardly extending tongues whosefree ends; are flared, said bracketiwhich are located within the wall terminating in flat flexible diverging tongues, and aflat Wedge arrangedwithin the opening: in the wall, said wedge being designed: to enter between and spread the tongnes apart- When the bracket is driven` home.

3. Awvall bracket formed of a single flat pieceof metal bent upon itself at one end,
