ALOYSIUS J. MAI-IR, OF ST. LOUIS, MISSOURI.
RAIL JOINT AND BRACE.
Specification of Letters Patent.
Patented Oct. 19, 1909.
Application filed June 1, 1909. Serial No. 499,270.
To aLL whom it may concern:
Be it known that I, ALoYsIUs J. MAHR, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented new and useful Improvements in Rail Joints and Braces, of which the following is a specification.
This invention relates to rail joints, and has for its object to provide a simple and effective construction of joint casting or splice chair for firmly uniting the rails and at the same time forming a continuous bridge for the passage of Wheels over the joint, and their spreading or deflection at the joint is prevented.
The invention consists of the features of construction, combination and arrangement of parts hereinafter fully described and claimed, reference being had to the accompanying drawings, in which Figure l is a cross section through a rail of the track adjacent the joint, showing the chair in end elevation. Fig. 2 is a top plan view of the parts at the joint. Fig. 8 is an outer side elevation of the same.
Referring to the drawing, 1 and 2 desigmate the meeting ends of the rails, and 3 the supporting ties therefor at opposite sides of the joint.
The improved joint chair or casting embodying my invention comprises a base plate at which forms a seat for the rails and is preferably, although not necessarily, let into recesses 5 formed in the ties. Integral with this base plate are inner and outer fish plates 6 and 7 which bear against the opposite sides of the webs of the rails and are joined to the base plate by union plates 8 which bear against the base flanges of the rails. Bolts 9 are preferably, although not necessarily, employed to fasten the fish plates and rails together in the usual manner. Each fish plate is provided at its upper edge with an outturned. bracing flange 10 to engage under the heads of the rails and support them against depression.
The outer edge of the base plate 4t is eX- tended to provide an attaching flange 11 arranged in the plane thereof and seated in the recesses 5, and which are perforated for the passage of spikes 12 to secure the same to the ties. This flange, the fish plate 6 and rails.
the adjoiningunion plate 8 and flange 10 are united by spaced vertical triangular bracing webs 13, whereby the splice chair is greatly strengthened and reinforced at its outer side. At its inner side the edge of the base plate is connected with the adjacent flange 10 by an inclined or diagonal brace bar or plate 14: extending the full length of the chair. From the lower edge of this brace bar or plate extend lugs or flanges 15 arranged above the plane of the plate 4 and which rest directly upon the upper surfaces of the ties and are perforated for the passage of spikes 16 to secure them to the latter, thus firmly fastening such side of the chair to the ties. The upper edge of the brace plate is extended to provide a bridge bar 17 which crosses the joint and bears against the inner sides of the heads of the This bar forms in eflect an auxiliary rail to assist in sustaining the Weight of the wheel 18 passing over the joint and 1s provided with a groove 19 to receive and form a tread portion for the flange 20 of the Wheel.
In the operation of applying the device, the ends of the rails are inserted into the space between the fish plates after the chair has been placed in position upon the ties, the bolts 9 applied, and the spikes 12 and 16 then driven, whereby the chair and rails will be firmly and securely fastened in position. The rails will thus be held and supported at the joint against both lateral andvertioal movement so that they cannot spread or become depressed. It will be apparent that the provision of the bracing webs and plate insures great strength and rigidity to the chair to sustain the strains falling upon it, and that by the provision of the grooved bridge bar the wheels of the rolling stock are supported at the joint and prevented from depressing and hammering the rails. The structure described not only secures these advantages and provides an economical type of joint, but also enables the parts to be disconnected for renewal or repairs when occasion requires.
Claim,
A rail chair comprising a base plate, fish plates rising therefrom and having flanges to support the rail heads, bracing webs unit ing the fish plate and base plate at one side of the chair, an inclined brace late uniting brace and arranged above the plane of the the base plate and fish plate at the opposite base. 10 side of the chair and extend-ing the full In testimony whereof I aflix my signature length of the latter, said brace plate having in presence of two Witnesses.
an extension forming a tread to support the ALOYSIUS J. MAI-IR. Wheels in passing over the joint and formed Witnesses;
With a flange receiving groove, and attach- GEO. WV. MATTHEWS,
ing flanges extending from said inclined WM. ALBRIGHT.
