To all whom, it may concern.-

Be it known that I, AXEL A. STROM, a citizen of the United States, residing at Austin, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Railway-Frogs, of which the following is a specification.

The object of my improvement is principally to supply a construction of frog which shall meet the requirements becoming more and more urgent on the part of users that the device shall possess as properties extreme lightness, comparatively speaking, necessary strength in the security of its connected parts, as also, of course, in the metal of which it is formed, accessibility of its parts for permitting readily the removal of dirt, snow, ice, &c., and economy of material. To attain strength in the device as a whole, frogs have hitherto, as a common manner of their construction, been rendered massive, and consequently heavy and correspondingly expensive, b y providing so-called filling in the spaces between the rails forming them. The filling also, as a further disadvantage, tends, owing to the height to which it is thoughtnecessary to have it extend between the rails, to cause fracturing of the flanges of the wheels of the rolling-stock as they become worn on their treads with use, causing the flanges cventually to meet the filling-blocks.

By my improved construction Iam enabled to dispense with the filling without thereby depriving the frog of the necessary bracing which filling a'llords between the rails and of convenient accessibility between the rails for removing accumulations of dirt, snow, ice, &c.

A further object of my improvement is to so construct the point of the frog that the shorter of the two beveled point-rails shall not, as hitherto, be liable to the effect of pounding by the wheels of the rolling-stock, which tends to sever the connection with its companion rail.

My invention consists in details of construction and combinations of parts.

In the drawings, Figure 1 is a plan view of a railway-frog of my improved construction. Fig. 2 is a horizontal section of the same, taken below the heads of the rails. Fig. is

a cross-section. Fig. at is a plan view of the blank before it is bent to form the brace shown in Figs. 1 and 2 between the frograils. Fig. 5 is a horizontal section of the frog, taken below the heads of the rails, and showing a modified construction of the bracing medium.

A A are the wing-rails,'of ordinary form, and B and B are respectively the shorter and longer point-rails. \Vhere the rail B is secured at its beveled surface to the point-rail 3 the laterally-reduced head portion. is beveled off on its top toward the extremity, as shown at 2' in Fig. 1, so that the wheels of the rolling-stock in moving onto the frog-point will not impinge against the extremity of the rail 13 and by pounding against it gradually sever its connection with the rail B.

C is a brace or truss, the form shown at opposite sides of the frog-point in Fig. 2 being produced from a blank, 0, of the shape represented in Fig. 4, comprising a metal bar, preferably of rectangular form and bent edgewise toward its opposite ends to produce upon the central or body portion, 0, the outwardly-oblique extensions p and the horizontal outwardly-extending extremities 02 The brace is formed from the blank by bending the latter at about the centers of the extensions p to bring the body portion oonaplane lateral to that upon which the extremities 71 extend, and thereby forming the ext-cnsionsp into troughs. The width of the brace is such as to cause it to lit in the space which receives it between rails, so that when adjusted in position the extremities 01, thus forming foot portions, are against the web of one (say a wing) rail, while the body portion 0 is against the opposing side of the web of the adjacent point-rail, the troughs p resting against the flange of the wing-rail, and the parts 0 and 72 of the brace being, by preference, beveled on corresponding sides toward the lateral edges, to cause them to conform to the angular shape of the spaces at the sides of the rails between the heads and flanges. \Vhere the :foot portions 91 are in contact with the web. they are secured to the latter, each preferably by two bolts, m, while the part 0 of the brace may be secured to the web of the adjacent rail by the rivets m, which secure the rails l; and 13' together toward their points, additional rivets being used, it? 1'o- (paired, as in .liig. 1, where the body portions of tho braees are slightly bout to bring thorn 5 against the opposite sides of the web of tho pointed portion of the rail 13' where it oxtonds beyond the rail I). ll desired, tho toot portion a at the end of a braee which is secured near the flaring oxtroinity ot' awing- 1o rail, may be bent horiztmtally, as shown in l igs. l and 2, to extend aeross tho spaee botwoen rails and all'ord a toot-guard, l.

A 't'rog thrnu'ah as deseribed, with braeos of tho emistruetion set ['orth,besidtsbeinglight- 15 and strong, presents no material obstruetion to aeeess between the rails for tho removal by sweeping or the like of dirt, snow, iee, &e.

A single braee maybe eni 'iloyed lorone side of a frog at the point, as in the ease of :0 spring rail-|'rogs.

'lhe braee may be modified in its eonstruetion, as shown in Fig. 5. The lattor eoinprises, praetieally, a seetion of tho braee already described, and whieh has one of the foot portions 11, the othor li'oot portion being atl'ordml by the severed seetion ol' the body portion. Thus, it desired, eaeh otfthebraeos tirst desm'ibe 'l may bo sovored bet\ve(,-n the troughs p near its opposite ends into two sootions, eaeh forming a shorter braee of tho :t'ords flanged bearings :t'or bracing the frogpoint at opposite sides and against the flan es of tho wing-rails, thoroby bracing the polnt not only against lateral but also agaii'ist ver tieal movement, the troughs which. are prae tieally flanges of tho braeo resting upon tho flanges ol' the wing-rails.

What I elaim as now and desiro to seeuro by TAtlilIOl'S Patent, 'is- 'l. In a railroad-frog or tho like, the eonib'ination, with adjacent rails, of a braeo,( 1, formed of a bent metal bar haying foot p0rtions it at opposito ends and an intm'mediziite trouglnp, snltst ant'ially as and For the purpose sot t'ort'h.

In a railway-t'rog, the Frog-point eoinprising a point-rail, l5, and a point-rail, 1i, soeured to tho rail U and having its wedgeshaped end bevelod on its upper side, as shown at r in a downward dircwtion toward tho pivoted end of the l'rog substantially as d eseri bed.

3. In a railway-frog or the like, the eoinbination, with adjaeentrails,ol' abr:'leo,(, eon1- prising a body portion, 0, having toot portions it at: opposito onds oxtending laterally ol' the body portion, and a tl()ll),'li,]), betwoon eaeh toot; portion and the adjaeent end of the body portion substantially asand tortho purpose set forth.

4. A rail-frog having its point braeed on opposite sides by means ot lianged landings resting tlatwise against? the z'uljaeent flanges of tho wing-rails and seeured tlatwise to tho web portion of the point,substantially as deseribed.
