1 o rill whom, it wuz i concern. lie it known that l, Cr-rA'nLns Anus ALDEN,

acitizen ot' the United States and residing ol which the following is a specification.

The present invention relates to methods of making railroad :t'rogs and product there of and more particularly to the production of such frogs l'roin rolled pressed or forged blanks as distinguished from castings,

The principal objects of the invention are to increase prod11 -tion and at the same time lower the costs. Further objects com *1 in the provision of a frog which has a rhinin'runi number of parts and is inherently strong and capable of standing up under all degrees 01 service.

To these, ends the method of this invention consists in operating: on a nietah preferably steel, bar 0t substantially unil o in cross section to alter the shape at a point adjacent where the wings are to end to provide for the flaring of the wings and increased widtn or the flange-ways at this point, and forming the flange-ways in the top oi? the bar to provide the wings anal point. If desired, the har may he heat treated atter the first operation.

According to the present invention the frog is constructed from a rolled, pressed,

or forged blank or bar, of substantially uniform cross section' Thus one form oi": bar which may be used is illustrated in Figures 1 and 2. Asshown,thisbar or blank 40 is of substantially uniform width and height throughout its length. In this form it is also of substantially uniform, cross sectional area and shape throughout its length. Preferably, the bar is substantially U-sl1ape, having a longitudinally extending recess 01' groove 41 opening from its bottom face. At the lower edges of the longitudinal side faces the bla-nk niay be provided with oppositely extendingbase flanges 42, the bottom surfaces of which are flush with the bottom of the bar. up into a plurality of forms of frogs, such as shown in Figuresfi, 12, 13, 14 and 21. For making a frog like that shown in Figures 6 and 12, the first step consists in operating on the bar of Figure 1 to alter the cross sectional shape at a point intermediate the ends of the bar. This operation is for the purpose of providing for the flaring of the wings at their ends and the increased width ot' theflange-ways adjacent the ends of. the wings. As shown in Figure 23, this operation consists informing the two rece es l3 substantially triangular in plan view and spaced transversely of the top Oil the bar and l'u'rther in forcing out the outer walls 4:4;

bounding these recesses so that the bar is widened at this point; This may be accomplished by indenting the bar as by a roll ing, hammering, or pressing operation. The groove 4L1 at this region may simultaneously be widened and made deeper as shown by the cross sectional view, Figure 9. If de sired, the Work may be subjected to a suit This bar may be worked he observed that the cross sectional area on. the line 5-.5 is

substantially the same as tho orlginal cross sectional area of the blank,

the shape only having beenchanged. llreterably at the same time that the cross sectlonal shape of the blank is altered at the desired point, the flanges 42 adjacent theends of the bar may be offset toward the top of the bar a little, as indicated at et5,i 'or a purpose presently to be described.

The next step in the method consists in operating on the top of the bar to form the flange-ways L6 and li", these flange-ways in cluding the recesses 43. Preferably, the flange-ways are formed by removing the metal from the top'of the bar as by i'uachining, thus providing the opposite wings i8 and 4:9 corresponding to the wing rails of frog, and also providing the point (30 corresponding to the point rails. It will be noted that the ends of the wings are -flared out. wardly as indicated. at and 51., and that the flange-ways adjacent thereto are thus widened.

For the purpose ot providing neans tor securing the truck rails to the frog a recess is n'iade in each end thereof thus forming the projections or splicinginembeis 5E2, 523 at one end of the bar and 5st, at the other. As previously explained, the flanges ii are offset upwardlyat the ends 0 the frog, the object being to permit the projections at th ends of the frog to properly fit against lhe web of the track rails, as shown in Figures 7 and 11. For this purpose, it will be noted that the tops of the projections are cutaway and beveled to fit under the heads of the rails. .s'fr spreader piece56 which is separable from the frog is interposed between the track rails at one end ot the frog and a similar piece 57 is disposed at the opposite end, The track rails are secured in position by means suchas the bolts 58 which extend tljn'o'ugh. the projections, the ends of the tract: rails, and the separator piece. The oi the trog at the ends is il i' [he some as that of the original b. and hence the end projections or splhing nieinl'iers 52, o f, 531] and are slightly tapered as shown. whereby rails take the proper directions relative to the trog. I Figure l3 shows a slight uunlilication in which the nd projectimis or splicing inenn hers l o] the same n 'idth throughout their length. In order to accommodate the track rails therefore these projections or splicing memhere are slightly flared or. bent apart, a suitable separating block, as indicated at 156 and 153 are not tapered but are r.

bein in'o\'ide h and all the parts being secured together as by the bolts 58. it is to be understood that a similar iistrueture may be employed at the other end the from F igures 14;, 15 and 16 show another modification of the structure at the ends ot the frog. In this case the structure is the same as that shown in Figures 6 and 12 except that part of the sepa ator between the track rails consists of a projection 256 integral with the frog. This projection is of a thicle ness substantially equal to the distance between the top of the groore 4:1 and the bottom of thetiange recess in the frog, and shaped at its sides to fit against the track rails as shown in Figure 15. The remainder of theseparator is formed by a separable piece 256 disposed under the inter; '211 piece 256. The parts are held together by the bolts 58.

Another form of frog is illustrated in Figure 21 and this frog; may be made from the blank shown in Figure lby operating on the same to form the work or bar shown in Figure 17. The blank has been operated on in any suitable way as by a rolling, pres or hammering operation to change the cross sectional shape of the bar at two points. At one point, as indicated by the cross sectional view of Figure 19 the top of the bar is widened in the same way as described in connection with l ig'ure 3. Kidjacent this section 1919 such as a: a tion 20 30, the bar has been narrowed and its height slightly increased, the cross sectional area however. ren'iaii'iing substantially the same. After this operation the bar or work may be subjected to a suitable heat treatment.

Next, the work of Figure 1'? is operated upon. to form flange-ways 3% and 347 by machining and thus provide wings 3-48 and 345) and the point 360, the ends of tl e wings being flared as at 350 and 351. The added height shown in Figure 20, due to narrowing the bar is removed by maehii'iing or otherwise to give a Hat top surface on the point. I

For securing; the tra 'l rails to the frog, separable splice plates 352' and are eni- Z500 ployed at one end and 3M and 355 at the other.

The sides of the frog at its ends are niacl'iineiil out to take the splice plates indicated at Y ain'l 37L Figure 23, and and 37 Figure flat. lnterposei'l between the track rails are separating members at the ends of the biog oi suitable shape to hold the rails properly (iliverging. v consists oi an integralpart as 356 or 235?, and a separable lower part 356' or 357'. The ads are secured to the ends of the frog and the parts fastened together by the bolts The splice plates 352 and 853 are slightly bent, as shown in Figure 21, whereeach of which asthe splice plates 354- and at the other end of the i'srog are straight. lhe base flanges are removed at the ends of the bar to a point inside of the recesses 370 and 3'71.

l1 another modified form of the invention the frog; "may be formed from a solid bar of inii'lorm cross section such as indicated at 44110, Figure 26, this bar having the base flanges 4 12. The first operation consists in forming the recess or groove e stl in the bottom of the blank, this groove having different widths, as in-zilicated. in the plan view and sertional views Figures 29, 30 and 31. The blank is not widi'fned, except at the region where the wings end, s indi cated by the section of Figure 31. The cen tral part of the groove may be .nade deeper at" this section. After these operations, which slightly elongate the bar, the same may be subjected to a suitable heat treatment. 'llhereatter the top of the bar is formed with lan -ways 4 M) and 4&7, thus providing the wing; and 4&9 and the I p point 1-60, These flange-ways may betormed by removing: the metal as by machining.

The track "ails are secured to the frog at one end by the integral separator block 456, emo'vable bent splice plates 4:52, 458 and bolts 52%. At the other end the track rails are secured to the frog by the integral separator block 4-57, ""raig'ht removable eplire plates 5% and t and bolts As sheen in l hp ures 33 and 38. the integral sepa ator blo lts @156 and are properly shaped to 1 gains't the webs of: the rails between the base flanges and heads thereof. The sides of the bar adjacent the base of l ator blocks or extensions are chanrecessed to receive the splice plates.

me end the sides are formed with eases 'ii'0 and 42-71. tor the splice plates ano lb-"5 and t the other end the sides are lorn'ied with the recesses 4T2 and 47?- ;for the spli :e plates t5"; and The base flanges l-42 at the firstanentioned end ot the bar are cut away or removed for a length substantially the same said recesses no and 41-71 and are arrowed at the other end. Further at the first mentione l end the top H ot the bar is formed with the lateral, cut
