Porwoll, St. Cloud, Minn. Application October 28, 1937, Serial No. 171,599 6 Claims. (Cl. 72-405) My invention relates to devices for securing objects to walls and similar structures. While intended primarily for use in securing electrical loop in the mold b efore- the lead or other mold red thereinto so that the loop able material is pou the outer surface of the plug will be anchored in wires or pipes containing the same, it will be understood that the device may be employed for securing other objects which might be pipes for carrying things other than electrical wires. An object of the invention is to provide a device of this character consisting of a plug of malleable material such as pig lead adapted to be expanded produced by the molding operation. brick wall. After the plug l8 l2 have been inserted in said’ hole, the plug is 10 d by a suitable tool so pounded on its outer en the hole thereby ?rmly securing in a hole provided therefor in a wall or similar structure, and a ?exible element secured to and extending from said plug so as to be adapted for bending or twisting around the object which it is desired to support from the wall. It will be as to expand it in pporting struc the device to the wall or other su l4 and I 6 of wire ture.

The novel features which I believe to be char acteristic of my invention are set forth with particularity in the appended claims. The in vention itself, however, both as to its organiza tion and method of operation, together with additional objects and advantages will be best understood from the following description of 25 speci?c embodiments in which, form of the 15 for carrying wires ject primarily being a pipe P It will be understood such as electrical wires. that as many of the devices as a matter of course be installed at spaced in as are necessary may 20 tervals on the wall. t modi?cation in Figs. 4 and 5 show a sligh I4 is provided with a rubber which the branch It is apparent that if desired, a sheath 20. similar rubber sheath might be provi ded for the‘ 5 the device is adapted branch 16.

Referring ?rst to the form of the device shown in Figs. 1, 2 and 3, a wire designated in general by the numeral I0 is bent intermediate its ends 45 preferably nearer one end than to the other to form a loop 12 from which extend a branch 14 pipe.

The looped the plug 30 will be installed in similar manner portion of the wire is combined with a plug 18 50 of soft malleable material such as pig lead which may be readily molded into a plug of the desired size. The bent portion of the wire is looped around the plug so as to be attached thereto. This may be conveniently done by inserting the 55 hole‘ of 'a In order to install the device for use, a drilled or otherwise formed in the proper size is structure W such as a concrete or a supporting and encircling loop to the plug previously referred to. Fig. 8 shows a modi?cation in which a plug 36 in the form of a disk of ‘malleable material such as pig lead is employed. The plug 36 is provided with two in suitable mann er as by punching, 2,111,034 holes 38 and 40. In connection with the plug 36, a Wire l0’ which may be of larger size than the Wire I0, is employed. The wire I0’ is bent to form a connecting member [2' from which two branches l4’ and IE’ extend, these branches device will then be installed in a manner similar to that already described by providing a hole in 10 the wall or supporting structure and expanding the plug in this hole. The operation and advantages of my invention will be fully understood in connection with the foregoing description and the accompanying 15 drawing. The principle involved is substantially the same in all of the forms disclosed, this prin ciple embodying the idea of providing a plug of malleable material upon which a ?exible element is looped or otherwise secured, the device thus 20 produced being installed by expanding the plug in a hole provided in a wall or other supporting ible element having a portion thereof molded in said plug and a portion extending therefrom adapted to be bent around an object to be sup ported from the Wall. 3. In a device of the character described, the combination of a plug of molded malleable ma terial adapted to be expanded in a hole provided therefor in a wall or similar structure, and a ?ex ible looped element having its loop molded in said plug to provide two branches extending there from adapted to be bent around an object to be 10 supported from the wall. 4. In, a device of the character described, the combination of a plug of malleable material adapted to be expanded in a hole provided there for in a wall or similar structure, a strip of ?exible branches extending therefrom, and an enlarge ment containing a slot formed in the outer end of one of said branches, the other one of said branches being adapted to be bent around an ob 20 ject to be supported from the wall and the outer end of said second branch being adapted to be in structure. This device has been found to be very efficient in practice. The expansion of the mal leable material in the hole provided therefor gives .26 a very ?rm grip which holds more ?rmly the more serted through said slot and secured thereby. that force is exerted on the ?exible element tend 5. In a device of the character described, the ing to pull it from its anchorage in the wall. This combination of a plug of molded malleable ma result is due to the fact that the ?exible element is looped at the rear of the plug which is of malleable therefor in a wall or similar 1.30 or somewhat plastic material. Therefore any pull looped strip having its loop molded in said plug to exerted upon the loop causes the forward portion provide two branches extending therefrom, and , of the plug to be crowded out and ?ow against the an enlargement containing a slot formed in the Wall of the opening or hole in which the plug is inserted. This action was proved by tests which were made. I claim: 1. In a device of the character described, the combination of a plug of malleable material adapted to be expanded in a hole provided therefor in a wall or similar structure, and a flexible ele ment looped around said plug to provide two branches extending therefrom adapted to be bent around an object to be supported from the wall. 2. In a device of the character described, the ‘combination of a plug of molded malleable ma terial adapted to be expanded in a hole provided therefor in a wall or similar structure, and a ?ex 15 material looped around said plug to provide two outer end of one of said branches, the other one of said branches beingadapted to be bent around an object to be supported from the wall and the outer end of said second branch being adapted to .' be inserted through said slot and secured thereby. 6. In a device of the character described, the combination of a disk-like plug of malleable ma terial adapted to be expanded in a hole provided therefor in a wall or similar structure, said disk containing two holes, and a ?exible looped element having two branches passing through said holes respectively and extending from sa1d plug whereby the branches are adapted to be object to be supported by the wall.
