JOHN D. MCDOWELL, OF EVERGREEN, PENNSYLVANIA.

RAILROAD-TIE.

SPECIFICATION forming part Of Letters Patiitwo. 546,744, dated September .24, 1895. Application filed November 30, 1894. Serial No. 530,513. (No model.)

To all whono it may concern..-

Beit known-that L'JOHN D. MoDowELL, a citizen of the United States, residing at Evergreen, (Ross P. O.,) in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Railroad-Ties; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

The object of my invention is a railroadtie made of paper formed under hydraulic pressure, the peculiarities of which tie will be more particularly set forth hereinafter.

In the accompanying drawings, Figure 1 is a top view of one of myrailroad-ties as it will appear when on the track. I Fig. 2 is a side View of the same. Fig. 3 is a sectional view taken on line a a. Fig. 4. is another side view showing a portion broken away so as to see the position of the bolt and nut that I use,

and Fig. 5 is a cross-sectional view taken on line H H.

In the drawings, B B are railroad-rails.

D is the main body of the tie.

O is a cap or cross piece extending from side to side or from rail to rail and acts as a brace as well as a fastening for the rails.

'This cap 0 is held in place by bolts 9 g and nuts E E through the bolt-holes o o.

c o are the seats for the nuts E.

c c are the portions of the cap 0 that impingeiandrest on the inside of the rails, while '0'? c are enlarged parts of the tie that impinge or rest on the outer side of the rails.

prevent personsfrom walking on the tracks of railroads, I accomplish this by forming my railroad-tie with a ridge too narrow tov walk on. The shape of this cap C is seen in Fig. 5. The outer parts or ends of the tie will also be ridge shaped in part; but this does not reach clear up to the rail, for I form the tie at this point, next to the rail, with an enlarged part to give greater strength to the tie, a point where great strength is needed.

In forming the tie in the mold the bolts and nuts are placed in their places and thus the tie is made, and the bolt may be taken out while the nut is firmly embedded therein.

It will be seen by using a tie such as I show and describe no fish-plates are needed. Hence there is no need for bolts such as are used in the old way, as the bolting down of the cap 0 to the tie D will answer all purposes.

Having thus described my invention, what I claim, and desire to secure by Letters Patout, is-- 1. A railroad tie formed of paper in two parts 0 and D which have enlarged end portions to embrace the sides of the rails, as shown, and having registeringbolt openings, the partD having nuts E embedded therein,

substantially as specified.

2. A railroad tie made of paper having the two parts, 0 and D, the former having the parts cc and the latter having the parts 0 0 both being enlarged for the purpose specified, all substantially as described and shown.

3. A railroad tie formed of paper in two parts 0 and D, the part D having raised end portions to form seats for the rails and having enlarged portions 0 and the part 0 fitted upon the part D and having sloping sides and enlarged ends a, both parts 0 and D having registering openings for the bolts, and nuts E embedded in. the part D to receive the bolts by which the parts 0 and D are secured together, substantially as specified.

In testimony that I claim the foregoing I hereunto affix my signature, in the presence of two witnesses, this 15th day of September, A. D. 1894. V

JOHN D. MCDOWELL. [L. s.]

In presence of J. K. BARBOUR, SAMUEL D. BARNES.
