Specification of Letters Patent.

Patented Oct. 15, 1907.

`Application filed May 14,1907 Serial No. 373,534.

To all whom 'it may concer-n: Be it known that I, WILLIAM McCLoY, a citizen of the United States, and a resident of Cressona, county of Schuylkill, State of Pennsylvania, have invented cer# tain new and useful Improvements in Railroad-Ties, of

` parallel rails and my improved tie supporting the same;

Fig. 2 is an enlarged plan of one oi the rails and the adjacent parts; Fig. 3 is a section onthe line 3, 3, Fig. 2; Fig. 4 is a plan view of one of the bearing plates, and Fig. 5 is a view showing the form of the, outside clamps for use upon curves and where extra lateral resistance is required.

The tie A is oi metal, preferably bent up from a single flat rolled sheet of steel to form a bottom portion 1, and two parallel upturned side flanges 2, 2.

The rails X,AX, instead of resting upon the tie, have theirbearings upon Wooden blocks B, which are adapted to fit between the upturned flanges or sides 2, 2, and about the height of the latter, and upon each block rests a fiat plate 3, which is narrower than the distance between the upturned flanges 2, 2, so that it cannot possibly lrest upon, /or come in contact with the latter, the rail resting upon such, plate so that the resiliency of a wooden tie is secured, very much more extended than the area of the lower face of the rail sind equal to the area of the plate 3, infact giving the same qualities as the wood tie. l

The block is conned in place and the rails are held laterally in position by means of clamp plates C, C, each bearing with its side edge against-the side of the lower flange or base of the rail and each bent down at the sides to form flanges 5. 5, such a distance apart as to overlap. The side lian- ges 2, 2, of the tie and the flanges 5, 5, are provided with periorations for the passage of a bolt 6, which extends completely across the tie, and of shorter screw bolts 7, 7, each of which passes through the openin g in one of the flanges 5, and extendsinto the correspending threaded socket in the Harige 2 of the tie.. i By these means the Wooden bearing block oi the rails is secured in position between the anges and the aforesaid extended bearing for the rails is secured in position also, and in order to prevent the lifting of the rails 'as well as any shifting of the plate 3, each clamp plate G has in its edge a recess y, in such position that a bolt Y or ordinary railroad spikefdxiven downward through the of track is comparatively inexpensive.

said rec-ess will' also pass througha recess x in the underf lying plate 3, while the lip of the bolt or spike will overlap the bottom flange l,of the rail, as is usual.

It will be evident that all themetallic parts of the above-described construction except the usual bolts .may be formed yby bending up flat plates so that the tie may be made without the use of 'special machinery, and at a comparativelysmall cost, the only machinery required being to adapt the openings for the bolts Y, and to punch the holes a: and y Figs. 4 and 5.

It will also be seen that in substituting the improved metallic tie for the ordinary woodenl ties, the old ties removed from the track may be utilized by cutting them up into small lengths to constitute the. blocks B.

It will further be seen that all of the parts in the iinproved structure are absolutely lockedl together, that a most eective bearing is secured for the side thrust of the rails, and positively preventing spreading of rails, and that when the tie in all of its parts isembedded in the ordinary ballast the latter tends to prevent the bolts 7 and the nuts 'of the bolts 6 from turning, so that there is no danger of displacement. The construction also gives the tie more Weight to prevent creepings, etc.

It will further be evident that with a structure of the character described, if the blocks should become inelastic or rot, they can be 'replaced without the employment of experts, as any laborer can, after the removal of .the ballast, which it will be understood fills the space between the anges 2, withdraw the bolts and spike, knock the block out of place and. replace it by a 'new one, andreinsert the'bolts and spikes, so-that keeping i the road hed entire and without disturbing the surface In some situations it is desirable to have agreater support against the side thrust upon the rail, as for instance at curves, and to this end the clamps C may be provided with upturned lips 9 adapted to bear against the side of the rail and overlap the lower flange thereon, see Fig. 5.

Without limiting myself to the precise construction and arrangement of parte shown, I claim as my invention:

1. The combination in a rail tie of a continuous plate y 2. The-combination with a flanged tie A, of separated blocks, each fitting between the said flanges and extendin'g to the tops thereof, a. plate hear-lng upon the face of loo each block and narrower than the latter, and supported B, of plates resting upon the blocks and having `openings .1v and separated iianged clamps C, boltsonnecting the said clamps to .the tie, plate and block, and recesses y in the clamps coinciding with the recessesin the plates 3,

10 for the purpose set forth. l

4.The combination with the anged tie A, its blocks and plates 3, of separated clamp plates, the outer clamp` plates provided with lips 9, for the purpose set forth.

In testimony whereof I ax my signature in presence of two witnesses.

WILLIAM MCCLOY.
