Application filed May 31,

This invention relates to improved means for fastening rails in locations where the same must be secured to refractory material such as masonry or brick structures which are subjected to abnormal temperatures. .While, not limited thereto, the invention is well suited for use in securing the larry car rails to the top of a coke oven structure. The invention guard beam.

Referring in detail .to the drawings, 10 represents a body of refractory material such as brickwork or masonry used in the construction of coke ovens. The coke oven is formed withthe usual buck-stays 12 which are tied across the top of the furnace by means of cross rods 14 having nuts 16 thereon which engageplates or washers 18. 7

Rails 20-20 are secured, by my improved rail fastening device to be hereinafter described, to the top of the coke oven so as to guide the usual larr car 22 used in carrying the coal which is to e charged through openings' 11 leading to the coke chambers of the oven.

' Heretofore, it has been customary to secure the rails to the tie rods 14. In practice this is objectionable because it restricts the free expansion of the rail due to the abnormal heat of the coke oven. This frequently causes buckling or breaking of the rail and tends also to transmit objectional stresses to the tie rods and refractory material.

According to my improvement the rails 20-20 bear freely on pads or raised bosses of masonry 24 and the rails are held against displacement by clips 26 adapted to be engaged under the head of the rail as indicated inFig.

3 so as to abut the web 28 near the fillet joiningthe head to the web. Each clip 26 is provided with a base portion 30 which is seated on the upper surface of a beam 32 buried in the masonry and disposed substantially at right angles to the length of the rails. In the embodiment of the invention illustrated, the

beams 32 are formed of short sections of T- rail. The head 34 of each beam is notched at 36 and 38 for the reception of bolts 40 by means of which clips 26 are secured in place.

As thus arranged, it is apparent that the clips 26 are effective to maintain the correct gauge between the rails 20-20. Yet because of the relatively loose joint between the clips 26 and the web 28,. each rail is freeto expand independently under the influence of the terrific heat of the coke oven. Thus, elongation of the rails due to the heat, or contraction due to any change in temperature, will not set up destructive stresses in the oven structure. Each beam 32 as indicated clearly in Fig. 4 is spaced from the bottom flange of the rail 20 so that none of the load on the rails is transmitted tothe beams 32, this load being transmitted to the pads or bosses 24 above referred to.

While 1 have described -quite specifically" the particular embodiment of the invention illustrated, it is not to be construed that I am limited thereto since modifications may be made by those skilled in theart without departing from the invention as defined in the appended claims.

,What I claim is 1. A masonry structure formed with spaced integral bearing pads, rails seated thereon, means for positloning the rails on said structure comprising a beam whose top surface is below the level of said pads and clips secured to said beam. a 2. A masonry structure having spaced bearsition with freedom to expand and contract with respect to saidmasonry structure com-. prising transverse beams embedded in the masonry and clips secured to said beams and having ofi'set portions spaced above the base flanges of the fail, the extremities of said ing pads integrally formed thereon, rails clips being adapted to engage the web of the rail so as to prevent lateral displacement thereof.

4. A masonry structure having rails resting freely thereon, means for holding said rails against transverse displacement comprising beams disposed transversely of said rails and in said structure, bent clips having portions located in a plane immediately below the shaped to enga e the web of the rail under bottom surface of said rails so as to provide the head thereo and also having bearing por-' a clearance, and clips secured to said beams tions seated on said beam, the latterrbeing 15 5 having ofiset web engaging portions spaced notched and bolts extending through the above the base flanges of the rail, notched portions of the beams and engaging 5. A masonry structure, a rail supported the bearing portions of said clips.
