To all, whom it may concern:

' cation.

The object of my invention is the productionof an improved composite metallic and concrete tie for railways and improved trackrail fastenings adapted for use with the improved tie.

ful attempts have been made to design a composite tie which would meet the conditions required by actual service. Such ties for the most part have comprised a main body of con- Myi nvention accordingly consists in a com-- posite tie comprising a metallic beam having a flange or plain surface for receiving trackrails and a strengthening web or webs, the said beam being combined with a mass of concrete with the web or webs embedded therein for supporting the beam and facilitating the anchoring of the complete tie in the road-bed.

Further, it consists in certain novelties of constructions and combinations of parts hereinafter set forth and claimed. v

The accompanying drawings illustrate five examples of the physical embodiment of my invention relating to the tie and three examples of rail-fastenings, all constructed according to the best methods I have so far devised for the practical application of the principles. Figure 1 is a top plan view of a species of my improved tie, inwhich the main body'portion is a section of an old track-rail with its head and web embedded in concrete. Fig. 2 is a bottom plan view; Fig. 3, a side view; Fig. 4;, a section of Fig. 1 on line A B; Fig.

tail views of a track-rail fastening; Fig. 9, a View in perspective of the tie as it appears when supporting the rails. FigJlO is a top plan view of a second species of the tie,in which the main body portion is an I-beam with one flange and the web embedded in concrete; Fig. 11, a cross-section of Fig. 10. Fig.

g 12 is a top plan view of athird species of the Pr or to my invention numerous unsuccesstie, in which a bulb-beam constitutes the main body portion; Fig. 13, a cross-section of Fig. 12. Figs. 14 and 15 show plan and side views of a fourth species having a Tbeam as the main body portion. Fig. 16 isa cross-section ofFig. 15. Figs. 17, 1.8, 19 illustrate plan, side, and cross-section views of a fifth species, in which the main bodyportion is a U-shaped beam with its webs embedded in concrete. Figs. 20, 21, 22 show a second species of railfastening. Figs. 28, 24, 25; 26 illustrate a third example of the rail-fastening means.

Referring to the several figures, the numeral 1 designates the metallic plate or rail bearing surface in each ofthe five examples; 2, the web or webs integral with "or secured to the plate portion; 3, the head of the old rail, lower flange of the I-beam, and bulb of the bulb-beam; 4:, the concrete in which the web or webs and head, lower flange, and bulb of the beams are embedded; 5, the narrow central part of the tie; 6, the beveled sides of the tie.

7 designates holes in the webs of the beams filled with concrete; 8 inFig. 17, bolts which unite the webs of the main beam; 9, dovetail seats for bolts made in the top plate or flange of the main beam; 10, a clip having a dovetailed recess 11 in one side and reversely-bev- 'eled surfaces 12 to engage the flange of a rail;

13, a wedge-shaped washer witha dovetailed perforation 14: in the body and which fits under the beveled flange of the main body portion of the tie; 15, a threaded bolt with opposite beveled sides to fit the dovetailed recesses and perforation in the clip and other '5, a section on line C D; Figs. 6, 7, 8, 9, de- 1 i elements; 16, a locking-key with a recess 16, which enters a hole made in the end of the threaded bolt, and 17 is a nut.

Fig. 9' shows the location of the track-rails upon the metallic bearing-surface of the main element of the tie and the disposition of the clips and wedges of the fastening means ready to receive the threaded bolts.

In Figs. 20, 21, 22 is shown a second example of rail-fastening means. The numeral 18 designates a relatively wide recess made in the side of the top metallic main element of the tie; 19, a narrow recess in the opposite side; 20, a clip with a perforation 21 and a recess 22 in its under surface; 23, a threaded bolt with a perforation 24, beveled wings 25, and having one end 26 turned at a right angle to the body portion of the bolt; 27, a threaded bolt With a hooked end 28, engaging the recess 19 in the edge of the tie and having the threaded end passed through the hole 24 of the first-mentioned bolt, and 29 30 are nuts which fit the threaded ends of the two bolts.

In Figs. 23, 24C, 25, 26 is illustrated a third species of rail-fastening. The numeral 31 designates slots made in the metallic bearing face or flange of the main body portion of the tie; 32, a threaded bolt with an elongated beveled head of greater length than the width of slot 31 in the flange; 33, a clip with abeveled surface 34, perforation 35, and lug 36 upon its under surface, and 37 is a nut. In use the head of the bolt is dropped through the slot and revolved through an arc of ninety degrees, the clip passed over the bolt end and lowered, so that the lug 36 enters the slot and fills it, and the nut is then adjusted.

It will be observed that in most of the examples of the tie the same is made narrower in cross-section at the center than at the ends.

' This construction serves a twofold purpose.

It prevents the tie from becoming centerbound When the ballast works out at the ends under the pressure of passing trains or otherwise and the track settles, and it also anchors the tie in the road-beds and prevents its longitudinal movement, especially on curves, inasmuch as the inclined or angular surfaces at 38 form a bearing for the material of the road-bed.

In Figs. 17, 18, 19 I have shown plates 39 39 applied to the main metallic member of the tie, and they can when desired be used with the several other species of the tie, as shown in dotted lines, Figs. 1, 10, 12, 14.

In the manufacture of the tie a mold is made corresponding in length, depth, and width to the tie, the metallic beam placed centrally therein, the composition,consisting of suitable material-such as Portland cement, sand, gravel, limestone, cinders, &c.-in proper proportions, mixed and deposited in the mold around the beam and then tamped and subjected to heavy pressure. When the cement hasset, the tie is removed from the mold.

The process of manufacture and the elements selected for forming the composition can of course be varied to suit the circun'lstances.

From the foregoing description, taken in connection with the drawings, it is obvious that I have produced an improved composite tie which is comparatively cheap in first cost, easily manufactured, very durable, inasmuch as the concrete will prevent rusting of the metal embedded therein, exceedingly strong, and which will not be rendered unserviceable if the concrete should in isolated instances become cracked or broken.

In each of the examples a comparatively heavy metallic plate extends substantially the entire length of the tie, to the upper face of which are secured the track-railsaml from the under face of which projects a web or webs, firmly seated in the concrete or cement. 'lo securely anchor this web, in several of the examples a head or flange or bulb is employed integral or otherwise with the web or webs, and in other examples the web is perforated at intervals and the concrete forced by pressure to fill the perforations. One or both of these methods may be selected to insure the permanent union of the beam and concrete. In all the species the main body portion consists of a metallic beam provided with a lower portion of concrete, which latter supports the beam and gives the requisite bearing-s11rfaces in the road-bed.

.IVhile I have illustrated only five species of the generic invention, showing the best methods of applying the principle, I do not thereby intend to limit the scope of my invention to such examples, inasmuch as various modifications, changes, and additions maybe introduced in practice which will not constitute substantial departures. In some cases 1 may rivet to the under surface of the heavy bearing-plate a web or webs and flange or an angle-iron to form the beam,and l-may select a different shape for the tie as a whole; but all such details of construction I shall regard as colorable when the completed tie embodies the characteristics of my invention and is fashioned for performing the same functions.
