OTTO WVILLIAM MEYSENBURG, ST. LOUIS, MISSOURI, ASSIGNOR TO THE JOHNSON STEEL STREET RAIL COMPANY, OF KENTUCKY.
CAST-IRON B RACE-CHAIR FOR STREET-RAILWAY RAILS.
. V L SPECIFICATION forming part of Letters Patent No. 357,532 dated February 8, 1887. Application filed October 1, 1886. Serial No. 215,046. (No model.)
To all whom it may concern:
Be it known that I, OTTO WILLIAM MEY- sENBUuG, of St. Louis, in the county of St. Louis and State of Missouri, have invented a Cast-Iron Brace-Chair for Street-Railway Rails, which invention is fully set forth and illustrated in the following specification and accompanying drawings.
The object of this invention is to make a rail-chair which shall securely prevent the rails from either canting or-spreading outward; and it consists of the chair hereinafter described and specifically claimed.
In the accompanying drawings, Figure 1 illustrates in perspective a chair forming the subject of this invention, supporting a side bearing-rail, shown in crosssection. Fig. 2 illustrates in plan the chair and rail shown in Fig. l, the head of the rail being removed.
. taken off the clamp-bolt (I, used for holding In said figures the several parts are indicated by letters, as referred to in the following description. v
The main strain, tending to both cant and spread the rails, is that induced by the wheels of heavy wagons when the same are pulled out of the track, between the rails of which they are frequentlyrun.
In the form of chair herein shown the lower part of the chair A A is, continued upward, fitting snugly into and against the outer side of the rail F, as shown at B, ending in an upper portion, 1), immediately under the head of the rail. In order to properly support the continued portion of the chair, and to render the chair free from danger of easy fracture during handling or shipping, the same being made of cast-iron, and therefore otherwise liable to fracture, the,brace G is made to connect the upper portion, 6, with the base-plate c of the chair. By this means all strain is down the lower flange of the rail.
It will be noticed that the brace O is made which, by screwing up its nut e securely,
.A. Either or both of the bolts (if may theresufficiently thin to come in between the paving-stones without obstruction. By means of this brace absolute rigidity is secured to the rail and ample strength to the chair with the minimum of metal possible.
It will also be noticed that the width of the body of the chair need not exceed that of the 0 head of the rail, in which case the chair will be non-obstructive to the pavement.
The chair A is cored out for lightness, as clearly shown in Fig. 1, leai'ing webs of metal under the foot of the rail F. At one side the body ofthe chair is provided with a flange, a, through which a hook -bolt, (1, is inserted,
clamps the foot of the rail.
' The chair may also be provided, if desired, with a bolt, and nut g, forsecuring the web of the rail to the extended side B b of the chair fore be used, as may be desired.
The bolt fmay be either placed, asv shown 6 in the drawings, Fig. 2, on one side of the brace O or through said brace, a suitable boss being formed on the outer edge of said brace for the head of said bolt or its nut g to set up to and bear against.
The chair is spiked to the cross-tiesof the track in the ordinary manner through holes or slots 0 in its bottom flanges or base-plate c, as clearly illustrated in the drawings.
Having thus fully described my said railchair, as of my invention I claim A cast-iron'chair for girder-rails, substantially of the form described, offset to fit over one foot, against one side, and under the head of the rail, and provided with a side brace, as O, substantially as and for the purposes set forth.
