UNITED STATES OTTO W. MAILANEN, OF BERKELEY, CALIFORNIA.
Specification of Letters Patent.
Patented Nov. 12, 1918.
Application filed May 15, 1916. Serial No. 97,477.
To all whom it may concern:
Be it known that I, OTTO W. MAILANEN, a subject of the Czar of Russia, and a resident of Berkeley, county of Alameda, State of California, have invented a new and useful Nail, of which the following is a specification.
My invention relates to devices forsupporting metallic fabric upon a wall.
'An object of my invention is to provide means for supporting a metallic fabric upon a wall which it is intended to coat with cementor plaster.
Another object of my invention is to provide a nail for use in the construction of plaster coated buildings, adapted to secure the tar paper to the sheathing, making a tight joint therewith and at the same time provide a. support for the wire reinforcement over which a plaster or-cement coating can be laid.
Another object of my invention is to provide a nail of the class described which is adapted to be locked about the wire it supports by the blow of the hammer which drives it home.
The invention possesses other features of advantage somenof which, with the foregoing, will be set forth in the following description of the preferred form of my invention which is illustrated in the drawings accompanying and forming part of the specification. It is to be understood that I do not limit myself to the showing made by the said drawings and description, as I may adopt variations of the preferred form within the scope of my invention as set forth in the claims.
Referring to the drawings.
Figure 1 is a perspective view of the nail of my invention.
Fig. 2 is a perspective view showing a portion of wire netting secured to a wall bv my nails.
Fig. 3 is 'a sectional view through a plaster coated wall showing my nail in use.
Fig. 4 is a view partly in section showing a modified form of my nail.
In the construction of plaster coated or cement coated houses, it is necessary to provide means for supporting the coating upon the walls and causing it to adhere thereto. This is usually done by nailing strips of thin wood. in staggered relation over the surface of the wall, and laying on top of these strips, wire netting of suitable mesh which is fastened down by means of staples. Over thls surface the coating of plaster is laid, the wire netting and wooden strips serving to hold the coating in .place. This practice is not satisfactory and is objectionable for two chief reasons. It is a cumbersome process and relatively an expensive one on account of the time necessary to lay the strips and then fasten the wire to them; further, the sheathing should be covered with tar paper or similar material before the plaster 1s applied to prevent the passage of moisture through the wall, and it is obvious that in nailing down the wooden spacing strips and in fastening the wire thereto numerous punctures in the tar 'paper will be made, each of which may be the source of a leak. It is therefore one of the objects of my invention to avoid this piercit is necessary, to render the joint tight so that no leaks will occur. The nail of my invention, therefore, performs three main functions. It secures the tar paper to the sheathing; the point of puncture is rendered tight against leakage; and without additional piercing of the waterproofing, a support is provided for the reinforcing wire.
he nail of my invention consists of a body 2 having a'pointed end 3. Separating the body into two portions is the annular. skirt or flange 4, which may be formed from the material of the body and integral therewith in any approved manner. Preferably the flange 4 is dished, that is, shaped in the form of a flat, conical. surface, so that when 'ing of the weatherproof coating and where the point of the nailis driven into the. wood of the sheathing .5, the flange 4 seats snugly against the tar paper 6, holding it securely and at the same time making the puncture 7 leak proof. Theflange 4 also serves to limit the penetration of the nail into the sheathing so that all the nails project an equal amount above the'surface.
The length of the body below the flange 4 should be sufficient to give the necessary hold in the sheathing and conveniently may be of such length as to just pass through the sheathing. -At the upper end, the body 2 of the nail is provided with a head 12 which is partially separated from the body by a transverse groove or recess 13 which preferably is wider at the bottom than at the top. In using the nail, a portion of the wire screen 14 is allowed to rest in the recess 13. When the nail is struck to drive it into the sheathing the head 12 closes down over the wire 14: and retains it in the recess. By making the recess wider at the bottom, there is no tendency to sever the wire inclosed therein. The length of the nail body above the flange 4 is determined by the distance which it is desired to space the wire netting from the wall.
In using the nail of my invention, the tar paper is first put up with only suflicient fastening to temporarily retain it in place. My nails may be used for this purpose. The Wire netting is next spread and temporarily secured. The workman then proceeds to place as man nails as needed to permanently hold the paper and secure the netting: first, by a light blow of the hammer starting the nail, then placing in the recess an adjacent section of Wire and with another blow or two driving the nail home and closing the recess in which the wire lies. The same blows which drive in the nail serve also to close down the head over the wire. In this way a large surface is quickly covered with a minimum labor cost the tar paper is secured to the wall without holes therein to cause later trouble and the wire reinforcing or screen is properly spaced from the wall and held in absolute security. After this is done the plaster coat 15 is applied to the wall so that the nail shanks and wire netting are embedded therein.
In Fig. 4 I have shown a modified form of nail which differs from the nails shown in Fig. l chiefly in that it is made in two pieces instead of one. In this construction the flange 4 is formed separately from the body portion 2, and is a slightly convex washer which may be assembled on the point of the nail as a step in the process of making the complete nail, or left loose for the workman to place when the nail is used.
Preferably I prefer to galvanize all parts of the nails in order to protect them from rusting.
1. A nail having a head and a body, said body having a recess therein whereby percussion upon the head of the nail closes said recess.
2. A nail having a substantially straight body and a head partially separated from said body by a transverse groove in one side thereof whereby percussion upon said head closes the recess formed by said groove.
3. A nail having a body, and a head partially separated from said body by a transverse groove, said groove being wider at the bottom than at the top.
4. A nail having a recess in the body thereof adapted to be closed by percussion upon the head of the nail and having an annular flange intermediate its ends.
5. A nail havin a head partially separated from the b0 y of the nail by a transverse groove and having an annular flange intermediate its ends.
6. A nail having means intermediate its ends for limiting the penetration thereof, and provided with a recess adapted to be closed by the act of driving the nail.
7. A nail for securing wire fabric in spaced relation to a wall comprising a nail body adapted to be partially driven into the wall, means for making a tight joint between said body and said wall and means for securing said fabric to said nail body.
8. A nail having a dished flange intermediate its ends, the head end of said nail being provided with a recess adapted to be closed by the act of driving the nail.
In testimony whereof, I have hereunto set my hand at Berkeley, California, this 24th day of April, 1916.
