SPECIFICATION forming part of Letters Patent No. 445,839; dated February 3, 1891.

Application filed November l, 1890. Serial No. 370,023. (No model.)

To all whom t may concern:

Be it known that we, GEORGE N. MOATS and CHARLES R. ORAWSHAW, citizens of the United States of America, residing at Ironton, in the county of Lawrence and State of Ohio, have invented certain new and useful Improvements in Railway-Frogs, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention pertains to a new and improved railroad-frog, having for its obj ect the production of simple and highlyefficient means whereby the rails are firmly and securely locked or held to each other and to their bed-plates.

The invention comprises the detail construction, combination, and arrangement of parts, substantially as hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings`,Figure l is a top plan view of our improved frog. Fig. 2 is a cross-sectional View on the lineocx,Fig. l. Fig. 3 is a sectional view on the line y y, taken at right angles to Fig. 2. Fig. 4- is a cross-sectional view on the line ,e e, Fig. l. Fig. 5 is a View of the central fish-plate. Fig. (5 is a detail view showing the bed-plate and one of its securing lish-plates- Referring to the drawings, A designates a bed-plate, which is rigidly secured by spikes to the ties or sleepers and is provided with ears or lugs c, havings slots a. To the upper surface of this bed-plate are secured or formed integral therewith lugs or buttons b, which are designed to project up between the rails h b and h2 b2. To these lugs or. buttons b are rigidly secured brace-bars B, which at their ends bear firmly against opposite points of adjoining railsavherebyv the latter are firmly held in place with relation to each other. These brace bars and lugs or buttons have coincident holes or apertures, through which nutted bolts O are passed for firmly holding the parts together.

D D designate outer brace-plates which conform to the outer sides of the outer rails and the ends of the bed-plates, said braceplates being provided with holes or openings7 surface of which bear the inner curved portions of rails b', and into its vertex lit the V- shaped ends of the rails b2.

To the outer sides of the rails are secured curved brace-plates F, which are provided with slots or openings, through which ears or lugs e project, skew-back pins e2 being inserted through slots in said ears or lugs.

G is a central approximatelyT X-shaped shplate designed to fit snugly on the ribs or ridges e', said plate beinglocated at the vertex or extreme inner end ofthe frog. The raised sides g of this fish-plate are designed to fit snugly against the inner surface of the outer rails b', and in said ribs, as well as in the upper face of the fish-plate, are formed two grooves or recesses g.

H designates a series of nutted bolts, which are passed through coincident holes or apertures in the webs of the rails, two of said bolts being projected through the grooves or recesses g of the iish-plate, so as to hold the latter firmly in place.

The advantages of our invention will be readily apparent to those skilled in the art to which it appertains, and it will be especially observed that by means thereof a iirm and secure fastening is secured for the rails at every point, and the same are held in proper relation to each other.

IVe claim as our inventicn l. A railroad-frog comprising a bed-plate having a series of lugs or buttons and bracebars rigidly secured thereto, as set forth.

2. A railroad-frog comprisinga bed-plate having a serios of lugs or buttons provided with holes or openings, brace-bars having coincident holes or openings, and nutted bolts passed through said vholes or openings, substantially as set forth.

3.
