Our invention relates to improvements in wall brackets,

outside walls and whic when so inserted can be used for supporting electric conductors of all types, and which can also be used for thepurpose ofsupporting wire screens and also for the purpose of securing a trellis to a wall. A further object is to construct a bracket which isdesigned to be inserted in the mortar joints in brick or rock walls in such a mannert-hat the same will be retained therein and prevented from being pulled out.

A still further object is to construct a wall whichhorizontally and vertically, extendin cables can be supported along the outside 0 a brick or rock wall, the cable so supported being absolutely vertical.

A still furtherlobject is to construct a wall bracket by means of which conduits of all types, such as. electric conduits, drain pipes, water pipes, and similar tubular articles, can be secured to a wall in horizontal or vertical position.

In carrying out a body or shank portion 13 which is preferably formed of spring metal and galvanized so that it will not corrode readily. The forour invention we'employ ward portion 14 of the member 13 is provided with slots 15 and 16, the slots 16 being preferably wider than the slot 15 as illustratedin Fig. 3 Intermediate the slots 15 and 16 we also provide an opening 17 for the reception of a bolt or similar device. The forward or head portion 14 is also provided with an apron 18 which is bent downward at right angles to the portion 14. This apron .is provided with slots 19 and 20 and with a circul'ar opening 21. The slots 19 and 20 may be eitherof the same width or one of them may be made larger, the same as the slot 16, the purpose of which will be later described.

Formed integral with the body or shank portion 13 are wings 22 which wings are bent at an angle to the body portion 13 and are provided with a tapering portion 23. This tapering portion leads to the end 24 of the body or shank portion. The wings or flanges 22 as illustrated in Fig. 1 extend outwardly at an angle to the body or shank portion 13 so that when the device is placed in position,

these wings or flanges are forced downward and the inherent resiliency therein will cause-- them 'to have a rising tendency and securely bind the bracket in place.

In Figs. 4 and 5 we have shown a modified form of our construction in which a body or shank portion 25 is employed. This body portion is provided with a forward end or head 26, which has an apron 27 formed integral therewith. The body or shank portion 25 is provided with wings or flanges 28, which are bent inwardly as illustrated in Fig. 5 and which are provided with a taper- .35 which, while being termed a ring, is substantially U shaped in cross section and which has its ends 36 and 37 skewed. (See Fig. 9.) Certain of the edges of this adjustable ring are provided with serrations 38, which resemble saw teeth "and which make the ring adjustable as to the depth of insertion as will be later explained.

In Fig. 11 we have shown a snap ring 39 which is constructed of spring material as is the ring 35. The ring 39 is substantially U shaped and is provided with outwardlyprojecting lugs 40., these lugs being formed on the legs 41 of the ring. By our construction we are enabled to support cables horizontally or vertically on,either brick, tile or stone walls. In fact any wall which has horizontal mortar or cement seams, andwhen so vertically su porting such cable, pipe, conduit or the like, the following method is preferable:

A'plumb line is dropped down from the top of the building which gives a vertical direction. Then wherever the horizontal seams occur a chisel is used to remove the mortar or cement from the horizontal seams, it being understood, of course, that the brackets are inserted in the horizontal. seams and at predetermined distances apart since all these horizontal seams are spaced equally apart, while the vertical seams are usually 5 out of alignment with each other and therea cable,

fore it would be practically impossible to run conduit or pipe verticallyon a wall if the vertical seams between the bricks or stones were relied upon. After the mortar or cement in the horizontal seams has been removed, our device is inserted and driven home. Then if a vertically extending cable is to be inserted, we employ the adjustable or skewed ring shown in Fig. 9. I The cable is raised or lowered along the edges of the aprons 18 which, after the brackets have been placed in osition, are in vertical alignment and then t e skew rings 35 are slipped over the cable. It will be necessary in order to insert the skew rings 35 that they be sprung so that the ends 36 and 37 will be in alignment so that they can enter the'slots 19 and 20. The ring35 is then plished into the slots and due to the serrations 38, the rings can be pushed in and have the serrations snap over the edges of the slots so as to bind the cable tightly after which the ends projecting beyond the apron can be turned over by means of pliers so that there is no possibility of the same becoming loosened. This makes the adjustable ring 35 suitable for various sizes of cables, and, if'desired, a second series of slots may be placed between the slots 19 and first inserted in the opening 15 -.holes in the bricks or stone and 22,1 although in our .opinion this is not n- When using the forward portion 14 to support a plurality of independentwires, the snap rin 39 disclosed in Figs. 11 and 12 is employe ,and the manner 0 installing this ring is as .follows: Qne of the tongues 40 is y by tilting) the ring, the wires in the meantime having een passed over the forward portion 14. The ring .is then compressed .so that the other tongue 40 can be passed through the opening or sl0t 163 after which the ring is released and its inherent resiliency will cause it to spread outward as illustrated in Fig. 12 so as to bind the wires in place. It is to be understood, of course, that the snap ring 39 disclosed in Fig. 11 and the adjustable ring disclosed in Fig. 9 can be made of any size so that various diameters of cable or various accumulations of independent wires can be taken care of bythese rings, the essential feature being to construct a wall bracket, which is designed tobe inserted in the horizontal mortar 'oints of a wall and without the necessity of oring any when so inserted will be frictionally held therein against any outward movement so that various cables, wires, lattice work and other structures, can be secured against a wall having mortar or cement seams without the necessity ofboring holes therein, it merely being necessary to remove a certain predetermined area of mortar I between such bricks or stone.

While we have described our device as being inserted in the horizontal joints between bricks, stones and the like, we do not desire to limit ourselves thereto because our device can also be inserted in the vertical mortar joints of buildings without departing from the spiritof our invention.

While we have shown the apron as extending downward from the forward portion, we

do not desire to limit ourselves thereto as this apron might just as well extend upwardly from the forward portion and serve the same purpose.

It will also be understood that by our construction the wall brackets can be utilized to support cables, wires, etc. horizontally so that when a cable comes up from under ground at one oint, it can be carried horizontally along the uildings in that block and be tapped along various points where the individual wires are to terminate. In other words, by the use of our brackets a main lead can be brought up from under ground to a certain point and the cable or cables, or wires, branchmg therefrom, can be carried to their various destmations.

It will be observed that by the construction of our bracket it is held and secured in the o nt or seam between the bricks or stone by. a three-point elastic contact which points of contact are spaced apart both vertically and laterallv so that all rocking or tilting of the bracket is eliminated. It is. also desirable when inserted in the wall, the seam of which is not uniform in width.

Itwill also be observed that by-the use of our bracket it is not necessary to drill holes in the bricks or stones of which the wall is constructed and then insert expansion plates in order to hold the bracket in place. This has been found to be a serious defect in attaching brackets to brick walls in which such brackets necessitated the use of expansion plates because in drilling the holes in the bricks to receive the expansion plates, it frequently happened that the workman in drilling the hole drove the brick deeply into thewall. This driving in' of the brick resulted in numerous complaintsfrom the house-owners, whereas with our device only a small portion of the mortar or cement between adjacent bricks is removed and the bracket driven in without in any way disturbing any of the individual members out of which the wall is constructed. Having fully described our invention, what 5 we claim is 1 A wallbracket formed from a single piece of spring metal and composed of a head portion and a shank portion, an apron integral'with said head portion, said head porac tion and apron being provided with rectangular openings for the reception of'a fastening means, upturned wings tapering downwardly at their rear ends formed integral with the longitudinal edges of said shank portion and adjacent said head portion, and a skew ring having certain of its edges serrated adapted to e inserted in said openin s, said serrated edges to grip one ofthe' e ges of each of said openings whereby said ring can be adjustably secured therein.

2. A wall bracket formed of a single piece of flat spring metal comprising a head and a shank portion integrally formed and lying in the same plane, an apron formed integral with and along one edge of said head portion and at right angles thereto, and upturned wings formed integral with said shank portion, the rear portion of said wings being tapered downwardly to the shank portion 5o 'whereby the insertion of the shank portion in the seam, or joint of a wall is facilitated and a three-point elastic gripping'action in said seam is obtained. I I

In testimony whereof we have afiixed our signatures.
