WILLIAM C. FRANK, 0F JOHNSTOW'N, PENNSYLVANIA.

METALLIC RAILWAY-TIE.

Specification of Letters Patent.

Patented Apr. 13, 1915.

Application filed June 6, 1914. Serial No. 848,368.

To all whom it may concern:

Be it known that 1, WILLIAM C. FRANK, a citizen of the United States, residing at Johnstown, in the county of Cambria and State of Pennsylvania, have invented oer tain new and useful Improvements in Metallic Railway-Tics, of which the following is a specification.

My invention relates to an improved metallic railway cross tie and means for securing the rails to said tie.

One object of my invention is to construct a tie of either pressed or rolled metal, having rail seats struck up from each end in such a manner that it will have the proper amount of elasticity and rigidity. Furthermore my invention provides a bearing surface suflicient to prevent the settling of said tie under the load which is supports.

Another object of my invention is to construct a tie with expanded rail seats so that the ballast of the roadbed can be thrown over the two ends and the central portions of the tie, thereby further anchoring the tie in the ballast so that it can neither shift longitudinally nor transversely to the track, the tie being thus embedded in the ballast, will be to some extentprotected from corrosion due to the weather conditions.

A further object of my invention is to use in combination with my improved tie clips and bolts in such a manner that the rails may be shifted longitudinally, on the tie a distance of from one half inch to one inch, for such reasons as will be hereinafter described.

Referring to the drawings Figure 1 is a side elevation of my improved metallic railway tie, showing the track rails in section, secured to the tie by clips and bolts. Fig. 2 is a top plan view of the tie with the rails and the clips and bolts removed. Fig. 3 is a transverse section through the body portion of the tie taken on the line IIIITI of Fig. 1; Fig. 4 is a vertical transverse sectional elevation through one of the expanded rail seat portions of the tie taken on the line IVIV of the Fig. 2; Fig. 5 is a top plan view of the outside rail clip fastening with the bolt in place; Fig. 6 is a top plan view of the inside rail clip fastening with the bolt in place; Fig. 7 is a vertical longitudinal sectional elevation taken on the broken line VII-VII of Fig. 2 showing the manner of securing the rails on the tie; Fig. 8 is a vertical transverse sectional elevation of a portion of the tie taken on the line VIIIVIII of Fig. 7, showing an end view of the clip and bolt; and Fig. 9 shows detail views of short transverse blocks under the rail seats.

Referring to the drawings in detail :1 is my improved tie in general and it is formed by being rolled or pressed into a channel form with wide base flanges 4. From the channel form two rail seats 3 of channel section are expanded in such a manner that an opening 2 is left in each side of the tie. Extending beneath the expanded rail seat 3 is a channel support and stiffener 7 which is secured to the tie by rivets 8. Directly beneath the rail and between the rail seat 3 and the stifiener 7 is a short transverse hollow block member 9 shown as a channel section. Rivets 10 secure transverse member 9 to the stiffener 7. This block member 9 transfers part of the load which rests on the rail seat 3 to the support 7. The expanded rail seat 3 adds strength and stiifness where needed and this and the support 7 which are subjected to the impact of the trains not only distribute this impact uniformly along the base of the tie, but the construction contributes a certain amount of elasticity to the tie. In the top of the tie, which composes the rail seats, inside slots 6 and outside slots 5 are properly spaced to receive the clips and bolts which secure the rail to the tie.

When the rails 11 are to be secured to the tie, the elongated heads 19 of the bolts are inserted through the slots 5 and 6, after the rail has been placed in position on its seat 3. The portion 20 of the bolts being square, the bolts must be inserted in the slots until the squared portions 20 extend below the slots, then the bolts may be turned ninety degrees above the longer central axis of the bolt and drawn up until the elongated head 19 comes in contact with the rail seat and thus prevents a further withdrawal of the bolt. The outer clip 12 and the inner clip 13 are now placed in their. respective positions with the bolts 18 passing up through the bolt holes 17 through the clips. Lug 14 on the outer clip 12 and lug 15 on the inner clip 13 extend respectively into the slots 5 and 6 thus preventing the clips from turning about the bolts 18 as an axis after being once placed in position. The overhanging edges 16 of the clips engage and bear upon the top of the rail flanges. The spring lock nuts 23 are now placed over the bolts followed'by the nuts 22 after proper spacing of the rails the nuts are screwed up to the proper tension. 7

A chisel may be placed in the transverse grooves 21 in the ends of the bolts and the ends of the bolts expanded by means of said V chisel to prevent the nuts from coming off.

On curves the gage of the track must be increased in width a distance of from one half inch to one inch, and after the inner edge of the head of the rail has been worn of block 9 beneath the rail seat, indicated by the number 24 having a central opening 25 through the block and a perforation 26 at the top and the rivet holes 27 in thebottom of the block whereby it may be attached to the channel support or stiffener 7 Although I have shown and described my invention in considerable detail, I do not wish to be limited to the exact construction shownand described, but may use such substitutions, modifications or equivalents thereof, as are embraced within the scope of my invention, or as pointed out in the appended claims. 7 s

Having thus described my invention, what I claim and desire to secure byv Letters Patent is 1. A metallic railway tie provided with openings in the upright web portionsbelow the track rails the parts above saidopenings being expanded upwardly to form raised rail seats 2. A'railway tiewith uprightweb portions, laterally extending base flanges and an upper laterally extending face or seat portion, theweb. portions below'the rails being provided with openings and the upper portion above said opening being expanded upwardly to form deeper rail seat portions. 3. A metallic'cross tie of inverted channel section with laterally extending base flanges, the upright web portions below the rails being provided with openings extending longitudinally of the tie, the portions above the Copies of this patent may be obtained for openings being pressed upwardly to form deeper trussed rail seats.

4. A metallic cross tie of inverted channel -form, elongated openings in the web porprovided with integral rail seats of channel form in transverse section struck up and separated therefrom near the end portions of the tie thereby forming deeper rail seats.

7 A metallic railway tie provided with deeper rail seats pressed upwardly from the other portions thereof, a transverse block mounted beneath and contacting with the lower portion of each rail seat, a supporting member below each rail seat secured to the upper portions of the tie and adapted to carry the blocks aforesaid.

8. A metallic railway tie of inverted channel form with laterally extending base flanges, elongated openings in the portions below the rail seats, the part above said openings being pressed upwardly to form deeper rail seats, a supporting member extending longitudinally of the tie and secured thereto below each rail seat, a transverse member resting on said supporting member and adapted to'contact with the under portionof the rail seat, thereby further supporting and strengthening the same.

9. A metallic railway tie of inverted trough section, elongated openings in the web portions thereof below the rail seats, the part above said openings being pressed upwardly tovform deeper rail seats, a shorter inverted channel member extending longitudinally of the tie and secured thereto below each rail seat, a supporting block resting on said supporting member and contacting with the lower portion of the rail seat.

In testimony whereof I hereto aflix my signature in the presence of two witnesses.

:WILLIAM G. FRANK.
