UNITED STATES PATENT OFFICE.
\VILL MCLAIN, OF J OHNSTOVN, PENNSYLVANIA, ASSIGNOR TO THE JOHNSON STEEL STREET RAIL COMPANY, OF KENTUCKY.
TWO-PART SELF-LOCKlNG-L UG CHAIR.
SPECIFICATION forming part of Letters Patent No. 396,590, dated January 22, 1889.
Application filed March 8, 1688. Serial No. 266,613. (No model.)
To all whom it may concern.-
Be it known that I, ILL MCLAIN, of Johnstown, in the county of Oambria and State of Pennsylvania, have invented a new and useful Two Part Self-Locking-Lug Chair for Railroad-Rails, which invention is fully set forth and illustrated in the following specification and accompanying drawings.
The object of the invention is to provide a chair made, preferably, of rolled steel or iron, that 011 being brought into proper position on the rail securely locks itself on the same without the aid of bolts, keys, or other devices.
The invention will first be described in detail, and then particularly set forth in the claim.
I11 the accompanying drawings, Figure 1 illustrates the chair in end elevation, with a center-bearing rail, shown in cross-section, fastened in place. Figs. 2 and 3 exhibit the two parts or halves of the chair in perspective.
In said figures the several parts are indicated by letters of reference, as follows: A represents one half the chair, and B the other half; R, the rail; L L, the hooked lugs; N N,
the necks supporting said lugs, and O O the bends in the necks of the same.
I11 securing the chair to the rail the lug L of one of the pieces or halves of the chair is hooked over the lower flange of the rail R, the body of the lug passing under the rail. The lug L of the other half is then hooked on the opposite side of the flange of the rail. The two halves are now in such relative positions that the lug and its neck on each half of the chair are opposite the corresponding offset in the other half, and on said halves being driven together they are firmly locked, with the rail securely held between their respective lugs L L. In this position of its two parts the chair is spiked to the cross-ties, making a firm and rigid support to the rail.
The necks N N are bent, as shown at O O, to allow them to pass over and rest upon the main parts of the top of the chair and assist in forming the look when they are driven together.
Although a center-bearing rail is shown in the drawings, the chair may be so formed as to hold a girder-rail of any section. The blanks of which the parts of the chair are formed are so shaped as to be out without waste from a bar of metal of the width of the main body of the chair.
It is evident that while the lugs are shown adapted to a special form of lower flange of rail they can be equally well adapted to any form of projection on the web of the rail that will permit of a bearing for the hooks or lugs.
Having thus fully described my said improvement as of my invention, I claim A two-part chair for girder-rails, provided with a clamping-lug on each part for connecting rail and chair together by the interlocking of the parts without other fastenings, substantially as set forth.
W MOLAIN.
