Toallwlwm z'may concern:

Beit known that I, .BENEDICT T. GIBBs, J r., a` citizen of the United States,.residing at Chicago, in the county of Cook and State of` Illinois,'have.invented a certain new and useful Improvementin Reinforcements for Frogs and Crossings, of which the following is a specification. 4

Itis often' desirable and necessary to reinforce frogs, crossings and other track structures which are made .of castmetal in Ysucha manner that should the casting crack or fracture, the broken parts will be securely held in placey and kept inl proper alinement. ySuch reinforcement has hitherto been in the form of separatemetaliparts or straps whichlhave been bolted onto the casting structure; and due to the vibration of the track the bolts and reinforcement loosen and fail tork function.

The Yobject of this invention is to so reinforce suchcast metal frogs, crossings or other track structures, in the process of manufacture that the reinforcement becomes an integral part of the casting and cannot under any circumstances become separated therefrom; thereby holding all parts of the casting in proper place should breakage occur and thus preventing possible derailment of trains passing over the structure. A further object of the invention is to reinforce frogs, crossings or other track structures of cast metal with straps or barsk of non-readily breakable material, so shaped that they are' securely held and ybound in place by the surrounding cast metal. The invention further consists'in the means for doing this economically and pro-v viding a device which is satisfactory in use and is not readily liable to get out of Order. More particularly, the invention consists in the features and details ofy construction which will be hereaftervmore fully set forthl in the specication and claims.

Referring to the drawings, in which similar numerals represent the same parts throughout the several views. y

Figure 1 is a `plan view, partially in section, of a crossing embodying this invention in its preferred form.

Fig. 2 is a sectional view on the line 2-2 of Fig. 1. I

Fig. 3 is a side view of that part of the device illustrated in Fig. 2f

l Similarly, Fig. 4 is a plan view of a frog i embodying this invention in its preferred form.

Fig. 5 is a sectional view on the line 5-5 of Fig. 4:,and s f Fig. 6 is a side view taken at the right of of Fig. 5. V

lAshas'her'etofore been indicated, the in- `,vention applies' generally to track structures. y For the purposes of illustration, it isshown in the rst three figures, (1-3) as appliedto la crossingfof cast metal 10 and in the remaining figures (l-6) as applied to affrog'11.EXce'pt for the difference in shapecausedby'the'variations in formi between the crossing '10 and the frog 11, both of which will be -hereafterreferred to generically as the hard metalmember, the structures are the same and spondingly' lettered. f 1

v cast around pairs of reinforcing strips 12 of non-readily breakable material so placed that in the 1inisbed product they lie embedded in opposite sides of the casting and are held rmly in place therein. One means adopted for holding the strips in place consists in inclining ythe upper and lower edges 14 of the bars 12 to the vertical faces of the hard metal member so that the! bars are of greater height on their faces which are toward the center of the hard metal member than at the outer sides thereof. with the result that the metal o-f the hard metal member embraces each bar, as clearly appears in the drawings. to prevent lateral movement of the jloar with reference to the cast member. Again, the bars are held against longitudinal movement with reference tothe hard metal memloer throughvthe use of lugs 15, of the cast metal. lwhich enter `suitably formed y recesses 16 conveniently located along ythe top and bottom surfaces of the bars., Theselugs 15 obviously tend to prevent longitudinal movement of the bars with reference t the hard metal member, `Either one of these' methods maybe used singly.

The bars are further held in place by providing vcast metal knobs 17 -formed integral with the hard metal member itself which How into the holes 18 formed at convenient The holes may bemadetapered or cylindrical, as' desiree. The balk si ttes@ knobs preafl'e SO COITB" vente longitudinal' mover'nentl of' the When made tapered, the taper prevents latr-A eral' movement ofthe bare with reference to the hard metal member.l f

The result of the complete...construetionv shown and describedl is tli'ltthe hard metal members are forall members, which reducebreazkage in and prevent accidents due to breakage of the hard metal member.: y

Having thus described my invention, what Iclaim as new and desire to secure by Letters Patent, isz- 1. A railroad traokage striictiire of the Vto mafintain'ass'embl-y of con'stituentiparts of said memberupon" breakage thereof.ri
