DOOR-HANGER TRACK.

SPECIFICATION forming part of Letters Patent No. 402,843, dated May 7, 1889.

Application filed September 3, 1888. Serial No. 284,461. (No' model.)

To all whom it may concern:

Be it known that I, JOHN G. LANE, of Poughkeepsie, in the county of Dutchess and State of New York, have invented a new and useful Improvement in Door-Hanger Tracks; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention is an improved track, and bracket supports therefor, intended for doorhangers. It is desirable to supply these tracks to the trade in sections fitted to put up; and the object of my invention is to provide such a section of track complete in itself of simpler and cheaper construction than any heretofore known, so far as I am aware, each section being perfectly adapted to be secured in place upon the building and to contiguous sections.

In the accompanying drawings, Figure 1 shows a perspective view of a section of track; Fig. 2, an end View, partly in section; Fig 3, a horizontal sectional View.

In the drawings, A represents the rail, the form of which I have shown as consisting of a plain bar of steel set on edge. The bracket B is made out of steel, preferably. The bearing-face a is in plane parallel with the feet a c, and is fitted to bear against the inner face of the rail A. The vertical height of this face is made less than the vertical height of the rail, so that the upper edge of the rail projects above the bearing-face of the bracket. The upper leg of the bracket may be inclined, as shown, to give greater security, while the lower leg is horizontal to permit the door to move closely underneath; but I do not claim either this form of bracket or rail. They are the simplest form and cheapest to manufacture, considering their strength and lightness. The principal difficulty with this form of rail and bracket is to secure the rail permanently to the bracket, so that the bracket shall be held securely at right angles to the rail, and, further, to secure the sections to each other by simple and effective means. The rails, of course, maybe secured to the bracket by means of a bolt passing through round holes in the rail and bracket; but the difficulty with this form of connection is that when the sections are subjected to handling, as they are to a considerable extent before they reach the user, the brackets are knocked out of proper alignment with the rail and are liable to be come loose. This requires that they be reset and secured again in place for convenience in putting up and to prevent the rails from rattling. The obvious remedy for this would be to use square bolts or rivets and square holes; but the difficulty attending this is that the square bolts'are articles of special manufacture, and, further, that it requires very nice work to punch the square holes in the rail and the bearing-face of the bracket, so that their corners will exactly register with each other when the bracket is exactly at right angles to the rail. If one hole or the other he a little turned, as it is liable to be, then the bracket will be out of proper alignment. In order to obviate this difficulty, I have provided a construction of a soft-iron rivet, fitted by the upsetting action to holes in the steel rail and bracket, both varying in form from a circle. Square holes are punched without any special care both in the bracket and in the rail. The bracket is held securely in proper line at right angles to the rail, with a round rivet, d, placed in the square or angular hole in rail and bracket. The rivet is then upset with sufficient force to swage or press the round part of the rivet into the corners of the square or angular holes. The rail and the bracket being firmly held in position, the swage causes the middle of the rivet to fit the holes in that position. It is not necessary that the middle of the rivet should closely fit the corners. If it is so swaged that it will bear on the straight sides of the holes, it fixes the parts in position, so that the brackets cannot turn on the rail and the whole is held securely together and in proper position. It will be understood from this that the holes need not be exactly square, but may be of any angular form or a form varying from the circular section of the bolt, itbeing understood that both holes must be non-circular.

In order to secure section to section, I provide a coupling-clip, F, such as shown in a pending application filed by me in the United States Patent Office May 1, 1888, Serial No. 27 2,406; but while I have represented this coupling in the drawings Imake no claim for In testimony whereof I have signed my it herein. name to this specification in the presence 0f 10 I claim 1 1 1 two subscribing- Witnesses.
