SPECIFICATION forming part of Letters 1Patent No. 263,919, dated September 5, 1882.

' Application filed May 11, 1882. (No model.)

.To all whom it may concern Be it known thatl, CONRAD F. KREUZ, of Milwaukee, in the county ot Milwaukee, and in the State of Wisconsin, have invented certain new and useful Improvements in Railroad-Ties; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention Vrelates to Arailroad-ties, and is in part an improvement on the device patented to me December 20, 1881, and numbered 251,251, as will be more fully set forth hereinafter.

In the drawings, Figure l represents in perspective one form of my improved tie with a special key. Fig. 2 is a longitudinal vertical section of the same. Figs. 3 and 4 are detail views of the key and lock, and Fig. 5 represents another form of my tie without the described key.

In my patent above named Ifound it necessary to employ a system of three ties,each of the same general description, yet differing more or less in detail, and two of which were adapted tobeused alternately throughout the 2 5 length of a pair of rails, while the third tie was to be used whenever a second pair of rails were to be laid in continuation of the preced- 1n g p'air. In my present invention, however, all this is much simplified, and I may use indiscriminately the form of tie shown in Fig. l or the form shown in Fig. 5,'though both may be used to good effect, and wherethis is done the form shown in Fig. 1 with the extra key is best adapted for the purpose of uniting the ends of two pairs of rails, while the other form of tie, Fig. 5,.may be used for the intermediate ties. Again, when the grade of the road is very steep it may be desirable to employ the form of tie with the key, whereas on perfectlylevel road-beds the form 'shown in Fig. 5 will answer satisfactorily.

A represents the body of thetie, and this is formed of H bars or beams of iron, having a central web andupper and lower flanges. The upper flan ges are c ut or punched through transversely to remove the superfluous iron at the center a, and alsoou each side of this central cut-away, as show .n at b b, to receive the rails B B and at c c to receive the locks C C. 5o These locks C are either plain on the side or edge farthest from the rail, as shown in Fig. 5, or provided at that point with a central dovetail groove, d, extending from top to bottom, as shown in Fig. 4, to receive the central dovetail projection, d', on a key, D, Fig. 3, according to the grade of the road or the kind of service required, as already explained.

E E represent cushions interposed between the central web of the tie-body and the bottom `of the rails. Their function is to prevent jar- 6 ring and to deaden sound, and also to prevent the pounding of the surface of the rails by the car-wheels when the ground is frozen. -These cushions are to be made of either wood, rubber, felt, leather, paper, or a mixture of any of these, or any similar composition which possesses the qualities of ilexibility, durability, and elasticity.

I have designated by the letters a a the extreme ends ofthe side flanges of mytic above 7o the central web, and extending from each end of the tie to the outer side of each rail. Should I desire in any event to adopt the system of alternation that Idescribed in my former patent hereinbefore named, it would only be nec- 7 5 essary to remove (by punching or cutting in precisely the same Way, and, it' desired., at the same operation, in which the spaces c b c are formed) these end portions, c a', of my upper flanges, and then the rail would serve as an eX- 8o act substitute for the ra'il shown in Fig. 2 of my said Patent No. 251,251, to be alternated with my present complete rail. In Fig. 2 of my present case I have shown by the wholly white portions (marked a a) just' what would thus 85 be removed, as a portion of thelanges above the web should be retained in order to secure the cushions E against lateral displacement.

My ties can be made very quickly and cheaply from the H-iron bars or beams, as all portions 9o of the upper flanges which are to be cut away can be removed at a single punching operation thus leaving the body of my tie complete, and the lower flanges, beingleftintegral, will firm] y grasp the earth and lessen the danger of dis- 9 5 placement of the tie when once lai Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l.v A railroad-tie made from a bar of H iron, roo

the upper anges of which are punched through or out away, as shown at b o, in combination with the rails B and locks G, as set forth.

2. A railroad-tie made from a bar of H -iron, the upper Han ges of which are punched through or cut away, as shown at b c, in combination with the rails B, locks C, and keys D, as set forth.

3. A railroad-tie made from a bar of H-iron, the upper an ges of which are punched through or out away, as shown at b o, in combination with the rails B, looks C, keys D, and cushions E, as set forth.

4. In railroad-ties, the combination of the looks G, having central dovetail groove, d, eX- 15 tending from top to bottom, with the keys D, havin gcentral dovetail projeetions,d as shown and described, and for the purpose set forth..

In testimony that I claim the foregoing I have hereunto set my hand on this 10th day of zo April, 1882, in the presence of two witnesses.

CONRAD F. KREUZ.
