To all whom it may concern: 7

Be it known thatI, HENRY S. KrLBounNE, a citizen of theUnited States, and a resident of Nashville, in the county of'Davidson and State of Tennessee, have invented a new and Improved Railway-Tie, of which the follow ing is a full, clear, and exactdescription. j 'This inventi on relates to railway-ties and it consists substantially. in the details of con' struction and combinations of partshereinafter more particularly described, and point-- ed out in the claims. The invention has reference more 'espe-. cially to what may be technically designated 'a'sfarmored composition railway-ties and one of the principal objects thereof is to pro-- videa structure of this kind of an embodiment .to overcome numerous disadvantages and objections encountered in the use of many other structures of the kind hitherto devised.

A further object of the invention is to provide a railway-tic of the character referredz to which is simple in construction and comparatively inexpensive to manufacture, besides being thoroughly effective and reliable for its purposes and possessing the capacity for long and repeated service. v

A further ol 3 ofthe invention is to provide "a construc ion of tie which enables the rail to be effectively insulated and to provide an .improved'clamping clip of block adapted to be used with the railway-tie which will meet different requirements as to gage.

The above and additional objects are-attained by means substantially such as are illustrated in the accompanying drawings, in which+ I I Figure 1 is a top plan view of one embodiment of my invention. Fig. Z-is a side View thereof. Fig. 3fis an enlarged transverse sectional view talien on the line 3 3 of Fig. 1.

. Fig. 4 is a similar view taken on the line 4 4 ofFig. 1. f Figs. 5 and 6 are cross-sections through a tie of a'm'odified form, taken, respectively, near the ends and the middle thereof. Hg: 7 is a longitudinal section through a railwaytie, showing the construction 1 adopt for insulatiilgthe rail. Fi 8 is a perspective view of an adjusting bloc or clip, am Fig. 9 ,a plan of the clip justreferred to. 7

Before proceeding with a more detailed de 'scription it may bestated that I employ a specially constructed railway-tie the body of which is of suitable composition, as cegether and li'einforcing the parts of the structure, as will presently be explained.

ofthe desired dimensions and welghtnl tie may be employed. The central portion or waist 4 of the tie in the completed form of ends 5 of the tie, as shown, the said body beingof any desired. length and depth. In

constructing this formof my improved tie I may state that I' take a troughplateor channel-beam of steel or other desired metal,

said body completely 'fills the trough-like space formed by the armor. I 'preferablyera] .formhereinbefore explainedand then same hardcns the structure will-be practically inbefore explained, that the composition the depth which -itds desired that said body .gshall have in practice; The armor. of the tie referably extends to the ends of-the body tend beyond the ends of the body and he at e g original condition. .In this way-'1; derive ef-- fective means for preventing endwise disto the body 2 of the tie, as is apparent, since fill thehollow or trough-like space thereof with cement or concrete tov the desired depth' while m a plastic condition, so that when the a unitary one, it being understood, as here,

'by the designating characters thereon and special reference-to Figs. IV to 4,.inc1usive, 1 designates-my improved armored composition railwa'y tie- 1n; entirety, the same comprising a body 2 of suitable composition material,}preferably Portland cement concrete, and the bottom sur-'- face .3 of which is preferably flat," by which to-adapt the said body to be properly sea'ted 1 upon the bed of the railway upon which the (indicated at 6,) the flanges- 7 of which are z first'impart to the armor of the tie the gen- 1 iOC 80 the latter is contracted with respect to the guards or protectors therefor.

turned down against the latter ends as The armor, if found desirable in practice, may be shorter than the body of the tie. Ipreferin some instances to provide intermediate of the concrete body of the tie and the metallic armor thereof alayer a of Portland silica cement,

thusbringing the under or inner surface of the armor directly in contact with such layer, by which the said surface of the armor is protected from dampness and injury to the metal body of the armor by abrasion. As

a further safeguard against displacement of thebody and armor of the tie relatively to each other, any suitable means may be employed; but preferably I have herein shown suitable bolts 11, extending through corresponding openings therefor in the body 2 and channel-beams 6 at desired positions relatively to the ends ,5 of the tie, and which not only 'subserve the function just stated, but also serve to strengthen the union between the body and armor'of the tie, as well as furnishing convenient means for, the attachment or placing in position upon the tie of any preferred form of railway-fastenings that may beemployed in the use of the tie, it being mentioned that said bolts are extended sufficiently above the upper surface of the tie and externally threaded by which to adapt them for the said named purpose.

Also to furnish convenient bearings for the said bolts 11 atthe under side of the body 2 of the tie, as well aste impart rigidity to the structure at the places of location of the bolts I may providea diagonally-disposed plate 12 for each pair of bolts 11, embedded in the material of the body 2, flushly with the under, surface "of said body. These plates, if found desirable in practice, may be.

placed longitudinally of the body of the tie.

' I may adopt-the form of tie shown in Figs. 5 and 6, where Fig. 5 shows the cross-section i of the body 13 of the tie to be substantially the same as that shown in Fig. 3. T hearmorlate 14 has thesame form as before, having its flanges 15 'berit vertically at its middle portion. However, the width of the lower face of the body 13 is not reduced, so that oppositely-disposed recesses 16 are formed and laterally-projecting flanges -17. \Vith this form oftie' the bearing surface is' not reduced.

In Fig. 7 I illustrate a construction for securing. the rail to the tie, while at the same time insulating it from the tie. Such a construction as this is especially useful in connection' with railways having what is popularly known as a third. railthat is, a condiietorszail for an electric current. VV'th thiseonst ruction the armor-plate 18 caps the composition body 19 of the tie in the manner described above. The plate is provided at suitable points determined by the road-gage with openings 20 of enlarged diameter, and

in a substantially horizontal position and em.-

bedded in the tie-body, as" i1i(licated. The

I upper plate 23 is formed was. a flange 24 at its margin. Between the rail 25 and the tie an insulating-plate 26 of fiber or wood is placed, and on this plate the rail is laid. 'The bolts 21 pass upwardly through the insulating-plate and carry nuts 27, which screw down upon clamping-clips 28, which engage the flanges of the rail. The form of one of these clips is very clearly shown in Figs. 8 and 9. It consists of a'block which in one aspect may be considered to'be formed of two integral superposed thick plates 29 of substantially square form. These plates are not centered uioneach other, but are displaced diagona ly, so that projecting flanges 30 are formed on the four edges of the block. Two of these flanges overhang when the clip is resting on one face, and thei other two flanges will overhang if the clip is inverted. The inner faces of the flanges are beveled slightly, so that they may fit closely to the flange of the rail, as shown in Fig. 7 Each clip is provided with an opening3l, which receives the end of the clamping-bolt, and this opening is eccentrically placed on the clip, so that its distance from the clamping edges of the clip increases progressively,

preferably by a uniform amount, such as one sixteenth of an inch. In this way the reversiblc clip affords four positions in which the rail may be clampcd.\ Thus the clampingclip is given. a four-fold utility without inaterially increasing its mass. This adaptability or adjustability of the clip enables the gage of the rails to be varied accuratel where desired, and the clips are found useful in this connection on tangents as well as on curves. The corners of the clip which are most separated are preferably cut oil', as indicated at 32.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent A railway-tie having a compositionv body presenting a reduced waist with substantially vertical side faces at its middle portion lying against the sides of said waist, and inclined side faces at its ends lying against said inclined side faces of said bbdy.
