RAILROAD-TIE.

To all Who/n, it 11mg/ conc/rfi Be it known that l, Hoirvrio (l. Honor-I- rox, a citizen or' the United States ot' America, residing at Green Bay, in the county ot `Brown and State of lliseonsin, have invented certain new and uset'ul Improvements in lailroad-Ties, oi which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in railroad ties and has for its object the production of a practically indestructible tie provided with shock absorbing end block or rail beds.

A further object of my invention is to provide a tie with detachable shock absorbing ends, which ends may be quickly and readily detached and replaced without disturbing the tie proper and without making it necessary to replace the entire tie.

Heretofore in railroad ties' of this nature, which have been constructed throughout of concrete, molded in a variety of forms, the rigidity and non-shock absorbing of the material used, causes the tie to crack which entirely destroys the tie, and in several instances caused disastrous results. By the use of my improved tie, danger from this source is entirely eliminated, the end blocks being composed of a fibrous material preferably wood which serves as a bed for the rails and to which they are attached, are joined together vby an interposed block of some suitable adhesive material preferably concrete. It will be seen that by this arrangement, the wooden bed blocks will etliciently absorb the shocks without danger of cracking the interposed concrete tie.

W ith these and other objects in view, this invention consist of certain novel combinations, constructions and arrangement of parts as will be hereinafter fully described and claimed.

ln the accompanying drawings -Figure 1 is a perspective view-ot' my im}' roved tie, showing the shock absorbing ends secured thereto. Fig. 2 is a perspective view ot' my improved tie with the shock absorbing ends removed. Fig. 3 is a perspective view ol a shock absorbing end piece or blocl.' which is adapted to tit to each cud of the tie. Fig. l is a longitudinal, sectional view in elm/ation of my complete tie, showing the rails thereon..

Referring to the aceon'ipanying drawing, l represents the tie proper which is molded Specification of Letters Patent.

Application filed July 20, 1915. Serial No. 40,814.

preferably ot concrete and square in section. At each end of this tie l are transverse slots 2, adapted to receive the transverse tongue 3 formed on the end of each of the bed blocks al. These end bed blocks #l are made preferably of wood which has been previously treated by the ereosote process for preserving and are secured at meh end of the tie l so as to form a bed for the rails.

A tie bolt 5 screw threaded at each end and adapted to pass through the centrally positioned longitudinal hole G in the tie l and end blocks t so as to securely tie and bind the said ends to the tie l when the nuts 7 are tightened, forming the combination in al substantial one piece construction.

T he transverse tongues 3 prevents the end blocks 4l from moving out of alinement with the tie block l, also relieving the tie bolt 5 of considerable strain.

It will be seen that to renew the end blocks l while the tie is in place, the nuts 7 on the ends of the tie bolt 5 are removed, the blocks 4 may then be slid away from the tie l without disturbing the latter,new blocks can then be replaced thereon, the nuts 7 are again screwed on to the bolt 5 and screwed home.

From the foregoing description it will be seen that a very simple, cheap and durable Shock absorbing tie has been produced, and that the bed blocks can be quickly and cheaply renewed.

Various changes in the form, proportion and the minor details oit construction ,may be resorted to without departing from the prin` ciple or sacrificing any ot' the advantages ot the invention as defined in-the appended claims.

Having thus described my invention, what lt claim is l. A tie ot the class described, comprising 'a rectangular block composed ot plastic material, shock absorbing means adapted to t'orm a bed t'or rails secured at each end ot tbe said rectangular block, and a tie bolt adapted to pass longitudinally through the said shock absorbing means and rectangular block for securely binding the said parts together.

Y A tie comprising a. rectangular block composed ot plastic material, shock absorbing rail beds composed ot a fibrous material and adapted to be secured to each end of the ,said rectangular block and a tie bolt adapted to pass centrallyand longitudinally through the said shock absorbing blocks and rectangular block together.

3. A tie comprising a rectangular block composed of plastic materials transverse slots inthe ends of said block, shock absorbing bed blocks composed of n fibrous material and provided with transverse tongues adapted to fit the slots in the ends of said rectangular block, and 'a tie bolt adapted to pass longitudinally through the said parts for securely binding them together.

4. A tie comprising at concrete rectangular block having transverse slots in the ends for binding the said parts said Wooden blocks in alinement therewith,

and a tie bolt adapted to pass longitudinally 20 through the said Wooden blocks and concrete block for ,binding` the same together;

In testimony whereof I hereunto alix my signature.
