RAILROAD-TIE;

Italy, have invented certain new and useful Improvementsin Railroad-Ties, of which the following is a specification.

- My invention relates to a railroad tie and has for its object the construction of a tie of cement or similar composition in such *manner'as to eliminate the defects common to thatkind of tie, said defects consisting [principally in the di'l'liculty of obtaining a seat for the rail which shall be rigid and at the same time su'liiciently elastic as not to injure the rolling stock and cause an excessive'vibration of the road.

. 5 which constitute seats for the rails.

The inventionwill be understood by reference to the accompanying (.lrawings in which Figure 1' is a plan view of a tie-with the rails supported upon it; Fig. 2 a vertical longitudinal section on the plane of the line 22 of Fig. l; Fig. 3 a transverse. vertical section on the plane of the line 3 3 of Fig. 1 Fig. 4 a-longitudinal horizontal section on the plane of the line 4--4 of Fig. 2; Fig. 5 a horizontal section of a modified form o'l' block; and Fig. 6 is a view of one of the sets of reinforcing rods.

Similar reference numerals indicate similar parts in the several views.

The tie as herein described is pre'l'erably made of cement or shnilar composition molded to the desired form and proportions. 'l hecentral body portion] thereof isstrengthened by a longitudinal rib 2, and the end sections-3 have concave depressions 4 formed therein adapted to receive blocks The said blocks are preferably of wood and the rails (5 are secured thereto in any usual manner. ,The said depressions A are openended, that is they extend transversely of the tie from side to. side and the side walls. thereof are longitudinally crmvergent', the blocks 5 being correspondingly formed so that said. blocks will be firmly wedged in position; When laying the ties care should be observed to so place them relatively to each other that the blocks 5 oil-contiguous ties shall have their converging walls run- 5 tie in a longitudinal direction-Will be resisted.

ning inopposite directions. This will prevent any displacement of the blocks as a force tending to thrust the blocks of a given Specification of Letters Patent. Patented Jan. 21, 1908.

by the blocks of the contiguous tie: de-

pressions 4 are made slightly concave, as shown in Fig. 2 so as to leave a s ace between them and the bottom of bodks 5.1

This feature gives a certain degree of flexi-v bility to the blocks the vibrations being transmitted to the side walls of'the depres sions.

Instead of making the blocks 5 of a single piecel may make them of two pieces 7, as indicated in Fig. 5, adapted to be held in position by a key or wedge 8. This-permits of an easier method of adjustment for the slight differences in the dimensions ofsthe blocks and the depressions in the ties. The tie is reinforced by a series of iron rods 9 embedded in the lowerpart thereof and running longitudinally, and by a series ofcross rods 10 in the enlarged ends 3 below the depressions 4. A second set of rods 11 eX- part thereof, The rods 11 have secured thereto,'in the manner shown .in Fig. 6, short rods 12 inclined upwardly and having their centers depressed to forin loops which surround the depressions 4 to resist lateral tend longitudinally of the tie near the upper v thrusts of the block during the passage of trains. l l

If necessary to replace a block 5 1t 1S'S1l'llleicnt to remove the rail holding spikes, when by a blow on the smallerhcad of the block it may be easily pushed out of the depression, the construction permitting this Without the necessityof lifting the tics or disturbin the rails which they support. An additionai advantage is the lessening of the cost inas: 7 much as the rail seat or block 5 is the only part requiring renewal. g T/Vhat I claim and. desire to secure by Let tors Patent is:-- I

l. A railroad tie having depressions therein extending transversely of the tie from side to side, the side walls of said depressions being longitudinally convergent, and correspondingly shaped blocks seated in said depressions upon which the rails are adapted to be secured. '3. A railroad tie having depressions;therein extending transversely of the tie from side to side, the side walls of said depressions being longitudinally convergent, and corre spondingly shaped blocks seated in said dopressions'to which. the rails are secured, said,

tie being reinforced by rods embedded therein.

spondingly shaped blocks seated in-said dein, one series of said rods being bent to form loops which surround said depressions.

pressions to which the rails are secured, the bottom of said depressions being concave to providea space below said blocks.

In testimony whereof I have hereunto 15 signed my name in the presence of two subscribing Witnesses.

3. A railroad tie having den ressions therein extending transversely of t e tie from side to side, the side Walls of said depressions being longitudinally convergent, and correp ressions to which the rails are secured, said 7 me being remforced by rods embedded there GAETANO BOSSL Witnesses:
