Specification of Letters Patent.

Fatented Jan. 8, 1918.

Application filed April 17, 1916. Serial No. 91,705.

To all 'whom t may concern:

Be it known that I, ARCHIE D. CoALsoN, a citizen of the United States, residing at Birmingham, in the county of Jefferson and State of Alabama, have invented a new and useful Frog, of which the following is a specification.

This invention relates to railroad frogs, one object being to provide a removable point which, when worn, can be replaced by a new one, thereby avoiding the expensive renewal of the entire frog which has heretofore been necessary when the point has bef '001118 WOII).

A. further object is to provide simple and efficient means for holding the point firmly in position so that there is"` no danger of its working loose.

lfVith the foregoing and other objects in view which will appear as the description proceeds, the inventlon resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in/'the precise embodiment of the invention herein disclosed, can be made within' the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawin s the preferred form of the invention has geen shown.

In said/drawings Figure'l is a plan vlew of a frog embodying the present improvements, portions of rails being shown connected thereto.

Fig. 2 is a central longitudinal section through the frog. q

Fig. 3 is an enlarged section on line A-B Fig. 1. I

Fig. 4.- is an enlarged sectionon line Fig. 1.

Fig. 5 is an enlarged section on line\E-F Fig. 1.

Fig. 6 is an enlarged section on line G- 1. Fig. 7 is a plan view of the removable point.

Referring to the figures by characters of reference l and 2 deslgnate diverging wing rails and diver-ging i'rom the inner ends of these wing rails are flanges' and 4.' A substantially horizontal web 5 is interposed between and formed integral with the wing rails and the flanges and forms the bottom of the channel provided between the wing rails and lianges for the receptionv of the flanges of the rar wheels That portion of formed with yopenings 7 and the walls of the depresslon are preferably provided with longitudinal ygrooves 8 overhung by the adjacent upper portlons of the web 5. The 0pposed grooves 8 are designed to receive flanges 9 extending along the sides of a wedge-shaped point 10 which, when thrust longitudinally Within the depression 6 will fit snugly therein with its apex projecting upwardly from the apex of the depression. The base of the point rests on the bottom of the depression G as shown particularly in Fig. 1 and the top of the point is obviously disposed in the same plane as the tops of the wing rails 1 and 2 and the flanges 3 and 4. That portion of vthe point located beyond the web 5 is shaped to lie fiush with the bottom of the remainlng port-ion of the frog. This projecting portion of the point has base flanges 11 which may be secured to a cross tie by spikes in the usual manner. A tongue 12 is extendedfrom the end of the frog point, and the sides of this tongue arefparallel with the sides of the point. Longitudinal grooves 13 are formed along the upper edges of the sides of the tongue 12 and are' the top of the oint. The rails are fastened to the tongue y means of bolts 16 extending transversely through the webs of the rallsand through the ton ue 12.

'Basel fian'ges 1,7 exten outwardly from the "wingrrwltilsl and 2 and from the flanges 3 and 4 and also extend across the outer ends ofthe flanges 3 and 4 and lup to the sides of the oint 10. lThe inner sides of the wing rails 1 and 2 are out away longitudinally as at 18 to receive the outer sides of the heads of rails 1S). These rails are fastened to the wing rails by means of bolts 20 in the usual manner. Base ianges 2l are preferably provided along the inner sides of the wing rails and at the adjacent end of the web 5 and are adapted to aline with the (-orresjmlnling 'base flanges of the rails 1.9,'

Obviously when the point 10 becomes Worn it can be removed simply by detaehing vrails 14 from the tongue 12 and then Withdrawing the point longitudinally from theyA de ression 6.

he rails 14 are to be provided with fish plates 22 which lap and are secured to the i' ,sides of the point 10, recesses 23 being pro- "lo A i through the wing rai s and flanges, an integral web connectmgtheame and having a V-shaped including oppositely diverging ganarme depression between the flanges, there being longitudinal grooves in the Walls of the depression, and a point insertihle llongitudinally into the depression, flanges on the point adapted to enter the grooves, and flanges on the point adapted to seat on and for attahment to the ties.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature inthe presence of two Witnesses.
