Application filed December 7, 1917. Serial No. 205,927.v

To all whom it m my concern:

Be it known that 1, JOHN J. BRANAGAN, a citizen of the United States, and a resident; of McKees Rocks, in the ,county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Railroad-Ties; and I do hereby declare the following to be a full, clear, and exact description thereof.

lily invention relates to improvements in ties, and more particularly to metallic ties for railways, and has for its leading object the provision of an improved form of rail-- road tie having formed thereon an improved chair portion which will be durable and strong, and which will eliminate the necessity of using'spikesor bolts for joining and securing the'rails to the ties.

Another object of this invention is to provide a tie of this class which will positively prevent spreading of'rails atany time, and one which may be readily disassembled .to all ])w removal and replacement of worn rai s.

Another object is to provide a tie of the above mentioned class which will allow for the longitudinal expansion and contraction of the rails due to change in temperature.

. Other "objects, such as trussing and general reinforcing of the tie base and its as-,

sociated parts'in such manner as to facilitate rather than hinder the'planting of the tie will. be more fully brought out in the following specification and illustrated in the accompanying drawings.

It is well known that, in the use of the ordinary wooden tie to which bed plates, chairs and other such devices must be attached when layin' a road, when the rails ,themselvesare applied on these attachments they must be spiked in position and the rail joints bolted. v

Continual use of roads constructed with wooden ties will cause the spikes to become 'fore the; re-sctting of the ties and the application of new boits'and spikes are eliminat'edtas are also the bed plates, chairs and such other contrivances as maybe used. I In carrying out my invention I provide a channeled or hollowed base havin an improved chair portion at each end adapted to receive a rail and having movable parts in the form of wedges and clamping membersfin adapted to hold the rails securelyin ,posi-g, tion'. \Vhile I have shown and described one} particular form oi my invention ,.it willbe readily understood that I do not wish to .be '65 limited to the exact form shown, since viirious changes in design anddetails of structure ma be made without, departing from. the spirit of my invention asdefined inthef' appended claims. In the drawin s; -j"- Figure l is a plan view of asection of i road constructed with my improved tie; 1 Fig. 2--ie a sectional view on the. liiie'2 -2 of lrig' 1,3. 14? I F ig, 3 is an end view of oneof the tie s" having a rail therein; j'

Fig. dis a longitudinal sectional view of one of the ties partly broken awayr' Fig. 5 is a perspective view o ff;thf wedge member of my device;

Fig. 6 is a similar view ofthe clamping member; and i 7 V Fig. 7 is a view on the line 7- 7 at Fig? 6.

Referring moreparticularly'to the d'rawings, the letter A designatesthe -b'ase'of"inytieas a whole, which consistsof a' t op' Q and sides 3, formin a channeled porti'onfl 'l he base A is suitably braced within the channel by web tie members 4,, cross tie members'tio 5, and the side portions have reinforcing flanges 6 on their outer face spaced at inten' vals, which also serve to prevent lateral movement of the tie. The bottom surfaces of the base are slightly rounded, as at 7,1soa as to present a deflecting face to any objects they may strike when the tie has been set-on planted;

The chair members formed-at each end of. the base A'are identical in constructiomand therefore a detailed description of one of the chairs is deemed sufficient, it being understood however that the "same -.'reference numerals apply to the same parts of; both. chairs.

The, chair is formed ad acenttheendwf the tie and comprises a' locking.qfla'ng e's 8 formed integral with the t01l-100l3tl0fltlfii-llQ} base, having a suitably beveled gmoma (in,

its inner face adapted to receivethje base? 1 10 flange 10 of an ordinaryrail-111.; lTheftopi face 2 of the base has a suitable channel 12- termed therein and, a clamping member 13 adapted to be slidably mounted in said c liannel portion and comprises a rectangnla-r 1 portion H having a locking tongue i l and to'engage in the base portion of the flange 8, an upwardly extending necting rib 15, and a top portion which 'ber isadapted to be inserted within the channel 12 and comprisesa'lower wedge portion 21 and snapper wedge portion 22,

hai its side facesfen'gagethe side face of the clamping member-13 and the beveled porion of the transverserib or abntment 19, while the upper wedge portion 22 is adapted to engage the inside face of the connecting rib 15 of-the member 13, and to be held in such position by the overlying extension or fiangellfl, and; to also be engaged within the roove'20 in the abutment or rib l9, and is thereby firmly locked-in position.

lt -will be read'ly seen that "when a rail is placed inposition and the clamping member 13vis forced against the inside edge of the rail base 10, and the wedge 21-22 is driven into position, that the several parts will be bound firmly against movement.

After the wedge 21-22 has been driven into position,- a cover plate 23 having end flanges 24 extending downwardly therefrom present them" from becoming clogged by dust, dirt, etc, and to prevent their working loose.

To further strengthen the tie base,; a'

sfiange is engaged in the beveled groove 9 in the locking flange 8. The clamping member 13 is then inserted within the channel 12 and forced against the rail so that its flange '16 extends over and engages the other side of the. base flange 10 of the rail 11. The

A metallic tie of the class described comprising a base portion, a chair portion formed on each end of said base, each of said chair portions comprising Flocking flange adapted to, engage the base flange of' a rail, an upwardly extending abutment formed integral with said base and spaced from said locking flange, a clamping member' mounted betweensaid locking flange and said abutment, said clamping member comprising a base portion, an upwardly extendi n g connecting rib, and a top member extending transversely 'of-said connecting rib,
