Y DEVICE FOR ATTACHING FURRINGTO iNAliL-s,

SPECIFICATION formingpart of `Letters Patent No. 590,953, atea octber 5, 1897. Application filed September 26, 1896. Renewed September 7, 11897. Serial Noi 650,845 (No model.)

Be it known that I, WILLIAM Il. BARNns, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Devices for Ati taching Furrlng to lValls; and I do hereby declare the following to be a full, clear, and exact description of the saine, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.

My present invention has for its object to provide certain improvements in the means for attaching furring-strips and lathing or other materials to masonry, whereby the liability of its becoming loose isreduced to a minimum; vand it further has for itslobject to provide an improved furring-strip adapted for fireproof structures, well adapted for use in connection with the attaching means; and the invention consists in the hereinafter-de-` scribed devices, the points of novelty being pointed out in the claims at the end of this specification.

In the drawings, Figure l is a sectional view of a brick wall, showing the manner of attach'- ing a reproof furring and lathing; Fig. 2, a

horizontal sectional view through three furring-strips, showing the manner of securing them and the lathing also; Fig. 3, a perspective view of one of the wall-`plugs removed;- Fig. et, a cross-sectional view of the same, and4 Fig. 5 a view of a modified formof securingnail. Fig. 0 is a view of a modified form of plug. y l

Similar reference-numerals in the several figures indicate similar parts.

In securing furring-strips to masonry it has been customary to nail them to wooden plugs either builtin the wall between the stones or bricks or driven in an aperture in the mortar, but this arrangement is objectionable in that the plugs are liable to split or else they will shrink when securedin wet mortar to such 4an extent as to permit them to pull out, and with the object in view of obviating these dificulties' and also of providing a means whereby/the strips can be readily adjusted to make the walls vertical I provide plugs or sockets of sheet metal suitably roughened, corrugated, or crimped as to readily hold the securing-nails and adapted to be built in the wall or fastened in afterward. These plugs y consist generally of a socket l, of sheet metal,

having circumferential corrugations formed in it, which will serve to engage ribs or projections formed upon the surface of the securing-nail 2,` which is to be driven into it. As these sockets or plugs are preferably arranged between theV bricks or stonesduring the formation of the wall the mortar, (indicated by 3,) extending between the exterior ribs, will effectually prevent the withdrawal of the plus" The sockets canbe easily and cheaply made of a singlepieceA of sheet metal, crimped, roughened, or corrugated and rolled up into the flattened tubular form shown in Figs. 3 an-d 4, and I prefer that the exterior end of the socket be split for a short distance, as shown, and that the split ends 4 project beyond the lface ofthe wall in order that the .furring-strips (indicated by can be made plumb by bending more or less one or both of the split ends 4:, so that the strips which abut against them may be held a greater or less distance from the surface of the wall, as in Fig. l.

The shanks of the securingnails (indicated by 6) used in connection with the plug are corrugated, roughened, or ribbed circumferentially, so as tobind in the sockets, and while'they may be readily driven in their withdrawal is prevented, but the-heads of the nails may be of any desired construction. For instance, when wooden furring-strips are used the nail may have an ordinary head, as shown in Fig`. 5; but when my improved metal furring is used itis provided with a laterally-extended head, as shown in Figs. l and 2, adapted to project over the said strip.

The metal furring-strips, which are "partie ularly adapted for fireproof construction, are made of a single piece of sheet metal formed with double flanges 9 9 at each side and a central uniting weblO and resemble in. crosssection an I-beam. The outer flange at least ofthese strips is ofcolnparatively thin or bendable metal, andthe laths ll, whether of metal or wood, .are to be secured by stapleshaped nails 12, driven through the lath with the legs on opposite sides of the flanges of the strip and then set by a tool, such as 13, having a V-shaped jaw, which will bend the legs of the nail inward and also bend in the lateral edges of' the outer flange 9 of the strip and possibly the metal lath as Well, as shown at the extreme right in Fig. 2,1irmly clamping the parts together.

The Wall plugs or sockets can be made very easily and cheaply and are capable of use for other purposes than the attachment of furring-strips and may be used in connection with other forms of corrugated and roughened nails, though I prefer to form the corrugations in the nails smaller and closer together than those in the plug, so that the nail will hold even if driven in half the distance between two of the plugs corrugations to tighten it.

While it is not essential that the plug shall be elliptical in cross-section, I prefer this construction, as it affords greater latitude in the lateral location of the securing-nails, and such accuracy in placing the plugs in the Wall When building is not required as Would be if the nails fitted the plugs tightly at the sides, and I have found that the nails will be held suficiently'rigid for all practical purposes.

In some instances I prefer to make the corrugations in the plugs at a slight angle to the ends, as shown in Fig. 6, and While this will provide for holding the nails as described it Will also enable ordinary screws to be employed for holding the furring or other strips.

I claim as my inventionl. A tubular metal Wall-plug for receiving a nail and having a series of internal laterally-extending corrugations or ribs, substantiall y as described.

2. A tubular wall-plug, adapted to be built into a Wall and composed of sheet metal and having circumferential corrugations, subs'tantially as described.

3. A Wall-plug, composed of a sheet of metal bent int-o flattened tubular form and having external and internal circumferential corrugations, substantially as described.

4. A tubular metal Wall-plug, provided with circumferential corrugations and having an adjustable outer end, substantially as described.

5. A tubular metal Wall-plug, provided with circumferential corrugations and having the split outer end,substantially as described.

6. The combination with the sheet-metal Wall-plug, having circumferential corrugations, -of a corrugated secu ring-nail adapted to be driven into the plug, substantially as described.

7. The combination with a Wall-plug, having a flexible portion projecting beyond the Wall, of a metal furring-strip, having an outer flange, capable of being bent laterally, lat-hing, staple-shaped nails for securing the lathing to the strip, and a nail entering the plug and holding the strip, substantially as described.

8. A tubular metal Wall-plug consisting of folded and corrugated sheet metal, the corrugations thereof extending at an angle to the plane of the aperture, substantially as described.
