EVANC. PRICE AND GEORGE s. :snaw. or SPRINGFIELD, oHIo, ASSIGNOBS TO TH INDIANAPOLIS SWITCH ANDZFROG COMPANY, or SPRINGFIELD OHIO, a 00220- RATION OF INDIANA.

To all whom it may concern:

Be it known that we, EVAN C. PRICE and GEORGE S. SHAW, citizens of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Railway-Frogs, of which the following is a specification.

Our invention relates to improvements in railway fro s and it particularly relates to that class of frogs which are constructed of a hard metal. i

An object of the invention is to provide an integral frog structure which is constructed of a hard metal such as manganese steel which will have the maximum utility and at the same time be constructed at the minimum cost. p

A further object of the invention is to provide a fro structure which will permit of the connection thereto of full length main track rails without in any way altering the rails at the point of connection.

A further object of the invention is to provide a frog structure which may. be quickly and cheaply installed and also one which will permit the renewal of the main line rails without disturbing the frog struc-.'

ture itself.

A further object of the invention is to provide a structure which will have no unprotected joints between the structure itself and the main line rails, so that there will be no wear or wheel impact at the joints for a distance of a full standard rail length in either direction and on each converging rail from the frog structure.

A- further object is to' connect the structure to the maintrack rails with'the use of but one pairjof standard angle bar splices instead of"four,as is common.

g A further'objecto'f the 'invention'is ,to provide an integral frog structure of hardened material which will be of the'minimum 1 length to'admit of the connection thereto of the main track rails without in anyway altering said rails.

The invention consists in the constructions and combinations of arts hereinafter described and set forth in t e claims.

Fi 6 is a detail view of the clamping block. ig. 7 is a perspective view .of the same. Fig. 8 is a top plan of the base late. Fig. 9 is an end view of the base p ate. top plan view of the integral frog structure with rails detached. Fig. 11 is a vertical section showing a modification.

Like parts are represented by similar characters of reference in the several views.

Fig. 10 is a The point a, wing rails a" (1 base or filler 'b I), as shown in Fig. 3. The heel of the point on each side of the riser block or extension is shaped to conform to the ends of the standard main rails, which are connected thereto so that no altering of the abutting ends of the rails will be necessary. The sides of the riser block or extension a" are conformed to the shape of the converging main track rails, b b, and these rails are spliced to said block or extension by stand- .ard angle bar splices 6 these splice bars being also extended along and connected to the sides of the point a, which sides are of the same contour as the sides of the main converging track rails. The riser block or extension is tapered or inclined to receive the treads of the wheels as shown at a Fig. 5, and said block or extension at the point where it leaves the heel of the point is of sufficient width such as to prevent the false flanges of the wheels from running upon the opposite rail, this width being at least the width of the tread of the rall, although it may be greater. .Asshown in Fig. 1,-the width of the tread of the oint at its extreme rear end is substantial y equalto the combined widths of the heads or treads of the two main track rails, b and b, and the width of the tread of the riser block a whereit leaves the point, is approximately three times the width of the tread of one of the rails.

The forward end of the main body of the iregral structure is terminated at a point. where the width of the base thereof is substant-ially equal to the combined widths of of the structure are flanges or extensions (1 and d which form in effect continuations of portions of the base a and the wing rails (1' and (Z2;

The inner side of each of these ex- 1 tended flanges conformet'; to the shape of t the main rails and the main rails are connected thereto by bolts (F and d preferably twoor three bolts for each rail, spaced apart to agree with the ordinary splice bar holes j in the rails, which bolts are intended more i particularly to hold the said rails from longitudinal displac ii'ient or creeping. In

' within the structure itself,

order to secure the r. 5 against inward lateral displacement wehavc provided awedgeshaped block e, theonter sides of which are conformed to the shape of the rails. A rod. e extending longitudinally through a web a at the end of the main frog structure and},

also through the blockjc and provided with a head 15- adapted to bear against said web and with a nut e on its outer end, provides the preferable means for drawing this block up tightly betwcenthe rails, although it is obvious the other means n'nght be used for retaining or tightening this block. In order to allow for adjustment of the block, the block will be of such length as to leave a space between it and the main body of the structui as shown in Fig. 1. The sides of the wedge-shaped block, (a, are recessed as shown at e to receive the heads of the bolts 62'' and d", thus permitting the block to be drawn up tightly and also securely locking the bolts in position. In place of these bolts, lugs or bosses 1/" may be cast on the inner sides of the extensions (land (1, so spaced apartas to engage the holes in the rail. The

tit

block and the main rails form in eit'ect a continuation of the wing rails, 11". and the throat of the main structure and'thc block also acts as a foot guard and throat filler. The joints between the main track rails and the frog structure are protected by the hard inclined from their t'orwatd cnds rcar\\'ardl and take the false tlanges ot' the wheels. We preferably provide a' further clamping device in the nature of a base plate f, provided with a wedge-shaped recess f to receive the of the main track railsf \Vhen this entire structure 15 mounted on a continuous wrought plate, this clamping t-ie plate may be dispensed with and t ie forward end of the continuous plate. be provided with a wedge-shaped recess, acting in the same manner.

lly the construction described it will be seen that the integral hard metal structure is terminated at such points. both at the rear and forward ends, where it ,will be ust the necessary width to receive the main track rails without in any way altering the rails, so that the frog structure may be readily installed in the track without.thenecessity of having any short rail section: incorporated Further, when it is necessary to renew the main rails, new rails may be connected to the frog structure without the. necessity of shipping the same to the factory, as would be.t-he case where the frog structure is provided with short main line sections of special construction in integral frog structures of this kind.

The demand forand desirability of a manganese frog; structure depends greatly upon its rcasoiiable first costand a minimum expense for its up-keeping. It will, therefore, be seen that we have provided a manganesc t'rog structure which will have a maximum utility and at, the same time the cost of constructing the sameand its upkeeping will be keptat miniin um and the structure approaches as near as possible an integral hard metal structure as can be utilized. By providingthe special spl icing features described we'are enabled to shorten the frog structure and tlius eliminate all unnecessary amount of manganese steel. Further this construct-ion ma'kes a much safer and a .more durable substantial joint, permitting metal extensions 1/ and (l' which are slightly 5 the installation of the same in connection with the fllll l ngth track rails and also reducing-the nu berof'splicesrequired. This structure not only admits of quick installation, but also provides for ready repairing without. the necessity of ship )ing the frog structure back to the factory'tor renewal of any parts such as specially constructed short main rail sections. structure is also provided in which there are no unprotected joints for a distancc of the full standard rail length in each direction from the frog.
