Appiicafio'n mea January 22, 1912. serial No. 672,922.

To ill whom it may concemr Be itknown that. I, ROBERT W. ROSE- nRoUoH, a citizenof the United States, re-

` siding at Portland, in the county of Multnd mah and State of Oregon, have invented certain new and. useful Improvements in `Angle-Tracks; and I do hereby declare the followingto' be a full, clear, and eXact description of the invention, such as vvill enable others skilled in the art to which it appertains to make and use the same.

This invention relates to angle tracks and has for an object to provide a track especially adapted for use vin angletrucks similar to that disclosed in my copending apl plication Serial No. 12,1911, i c

A further object of the invention isto provide a track especially adapted foruse in connection with cable drawn ca rs and presenting newand improved features for 665,261 filed December carrying the cable and preventing the same'y from wearing t-he supporting ties..

IVit-h these and other objects in view the invention comprises certain novel constructions, combinations and arrangement of parts as will be hereinafter more, t'ullydescribed andv claimed.

In the drawings Figure 1 is a transverse sectional view of the improved track showing a cable. carrying roller of hour-glass shape. Fig. 2 is a view similar to Fig. 1 showing a cylindrical cable-carrying roller. Fig. 3 is a view of one of the cross ties showing one of the wear .plates in position. Fig. -It is a top plan view of one of the cross ties with a 'wear plate thereon and one of the supporting rollers adjacent' thereto, showing other cross tics without. supporting roll-A ers adjacent. Fig. 5 iswan inverted plan view of one ot' the cross tics showing a strcngtluning plat/e ouille bottom. Fig. G is a top plan view of a curve showing rollers for supporting the cable while passing about the curve. Fig. 7 is a transverse view ot' the track showing the position of a roller on a curve.

Like characters of reference indicate corresponding'parts throughout .the 'several views. v

It is well known that. where a car is drawn by a cable running above the surface of the track it engages upon certain parts olE the track and causes wear both ot' the track and the cable. 'lo prevent such undue wear the track comprising the rails 10 is provided with a cross ltie 11 tapered from-jj the opposite en s toward the,nddle'so` thatthe middle is narrower as indicated particularly'at Fig. 3..' The tapering of the tie to accommodate the angle truck formilgy Pen the subject'rnatter Aoit the'aforesaid cooFF'IoE- ROBERT -w. RosEBRUGH, orvPoR'rLAND, OREGON.

ing application weakens the tie at the middle Y p oint, as is obvious, and to strengthen such tie and also to prevent Wear'of the cable upon the tie a plate 12 is provided witlr'ar..

second plate 13 preferably of metal upon the under side of the tie so that the tie sits l upon the mud sill-13 covering the under- 'plate 14. The tie is preferably provided at the oppositeends with shoulders or exten-` sions 15 by which such tie is :secured to the mud sill 14 by ordinary spikesA 16.

Between certain of the ties 11, `as maybe found necessary, other shorter'mud sills 17 are embedded, carrying bearings 18 upon which are journaled rollers 19 or 20, the.V roller l19 being lsubstantially cylindrical, while the roller 20 is tapered from opposite ends toward the middle to form the middle with a waist.. The rollers are not providedi at each of the cross ties but are spaced` alongV as the nature of the trac may make necessary or desirable and under normal conditions support the cable `without engaging against the ties. When the cable is slackened for any reason it will occasionally engage the top of one of the ties intervening between the rollers and forsnch purpose the plates 12' are provided.

vFor rounding a curve, as shown at Fig. 6, the rollers 21 are set upon angle blocks 22 which-are secured to the mud sills 17, such angle blocks holding the rollers 21 at an inclination .to carry the cable as it passes around such curve.- It Will be neccssaryor desirable to employ a greater' number of such rollers about the curvey than under ordinary conditions and it maybe found desii-able to use one at each of the cross ties 11, as shown at Fig. 6.

I claim:- i

l. In a railway track. cross ties tapered downwardly.from opposite endstoward the middle, and means at the center of the ties for strengthening the ties and wear of the cable on such ties.

2. In a railway track, cross ties tapered downwardly from the opposite ends toward the middleylneans at the middle of the ties for strengthening the tics and prevent-ing wear of a cable on the ties, and aroller preventing- `the midle of the ties jou'emled adjacent ey cable out of uleptel normally support engagement with such weer means.
