MATTHEW J. DAWKINS, OF RIVERSIDE, CALIFORNIA,

RAILROAD-TRACK FSTENING.

Specification o' Letters Patent.

Patented March 28, 1909.

Application filed ctober 19, 1907. Serial No. 398,194.

To all whom it lmay cof/worn:

Be it known that 1, lviarrnnw J. Dawiiin s, l

a citizen of the United States, residing at Riverside, in the county of Riverside and State of California, have invented a new and useful Railroad-Track Fastening, of which the following is a specific ation.

The invention relates to imprmf'einents in track fastenings.

The object of the present invention is to improve the construction of traclr fastenings, and to provide a simple and comparatively inexpensive construction of great strength and durability, adapted to dispense with the ordinary iisli plates and bolts and also the spikes commonly employed for securing rails to the cross ties.

lli/lith these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

ln the drawing :e-Figure 1 is a plan view of a portion of a track provided with track fastenings, constructed in accordance with this invention. Fig. 2 is a detail sectional view, taken substantiallyT on the line .v-x of Fig. 1. Fig. 3 is a detail sectional view, taken substantially on the line yy of Fig. 1. Fig. 4 is a detail perspective view of one end of a cross tie. Fig. 5 is a detail view of one of the clamping members for engaging the outer faces of the rails.

Like numerals of reference designate corresponding parts in all the figures of the drawing.

1--1 designate rails divided longitudinally to form two similar sections 2, which have inner vertical faces 3, as clearly illustrated in Fig. 2 of the drawing. The sections of the rails are arranged to form lap joints, the ends of one section being located at the center of the adjacent rail sections, whereby practically a continuous rail is formed to eliminate the jars and vibrations incident to the passage of the wheels of a train over rail joints in which the ends of the rails are spaced apart.

The rail sections may be of any preferred length, and the rails are connected by cross ties, arranged at each of the seini-joints, as clearly illiastrated in Fig. 1 of the drawing.

Each cross tie is composed of a pair of clainping heads 4 and connecting rods 5, having parallel portions extending across the space between the clamping heads. rfhe clainling heads, which are rigid with the rods, may be cast, welded, brazed, or otherwise conf nected with the saine, andthe terminals 6 of the rods project beyond the clamping heads, and are threaded for the reception of niats 7 for securing clamping members S on the ends of the cross ties. Each clamping head is provided with upper and lower j aws 9 and 10, arranged to engage the rail and a stringer 11, which is located beneath and spaced from the rails. rlhe Stringer 11, as clearly illustrated in Fi. 2 of the drawing, is of slightly greater width than the bottom of the rail, and it projects laterally beyond each side of the saine. The clamping head 4 is also provided at an intermediate peint between the jaws with an outwardly extending rail-s'apporting portion or plate 12, havnig fiat horizontal 'up per and lower faces and presenting a flat supporting snrface to the bottom flanges of the rails. The upper jaw 9, which is arranged at an inclination, conforms to the configuration of the bottom flange and web of the rail and it extends upward to and engages the head of the rail. The lower depending jaw 10 is provided with an inclined engaging face and the string 11 is downwardly tapered to provide downwardly and inwardly extending inclined side faces 13.

The horizontal rail-supporting portion 12 of the cross tie extends a short distance beyond the rails, and the clamping member 8 is provided with an oblong horizontal opening 14 to receive the outer end of the railsupporting portion 12. The clamping member 8 is provided with upper and lower jaws 15 and 16; the upper jaw 15 conforms to the configuration of the bottom flange and web of the rail and extends to and engages the head of the rail, and the lower jaw 16 has an inclined engaging face to fit against the inclined face of the Stringer 11. The outer face of the clamping member is rounded at 17 to enable the clamping member to adjust itself to the rail and the Stringer when the nuts 7 are screwed home. A washer plate is preferably interposed between the nuts and the clamping member, but it may be omitted if desired. W hen the parts are beneath it troni the outside ot the rails without digging ont the gravel or ballast between the rails.

Having thus fully described rny invention, what l claiin as new and desire to secure by .Letters Patent, is

l. ln a device of the class described, the combination with stringere, and rails, of a cross tie provided at its ends with heads iaving upper and lower jaws, and clamping members also provided with upper and lower jaws, said heads and clamping meinbers cooperating to clainp both the rails and the stringere.

2. In a device oi' the class described, the combination with a rail, and a Stringer, oi' a cross tie provided with a head having upper and lower jaws 'for engaging the rail and the stringer at the inner side thereof, and a clamping ineniber secured to the end oi' the cross tie and. having upper and lower jaws tor engaging the rail and the Stringer at the outer side thereoil.

3. ln a device oil' the class described, the combination with a rail, and a Stringer, ol' a cross tie provided with a head having upper and lower jaws `for engaging the rail and the Stringer at the inner side thereof, said head being also provided with an outwardly projecting rail supporting portion interposed between the rail and the Stringer and spacing the iornier above the latter, and a clamping ineinber secured to the end of the cross tie and having upper and lower jaws for engaging the rail and the Stringer at the outer side thereol'.

Al. ln a device oi the class described, the combination with a rail, and a Stringer having inclined side faces, ot' a cross tie provided with a head having upper and lower jaws for engaging the rail and the stringer, the lower jaw being provided with an inclined i'ace to iit the said Stringer, and an outer clamping nie/inber adjustably secured to the cross tie and provided with upper and lower jaws for engaging the rail and the Stringer, the lower jaw being also provided with an inclined en` gaging 'tace to iit the stringer.

5. ln a device oi the class described, the combination of a cross tie coinposed of rods having threaded terminals, and a head rigid with the rods and provided with upper and lower jaws, an outer clamping inen'iber arranged on the outer end of the cross tie and cooperating with the head and having upper and lower jaws, and nuts mounted on the threaded ends of the rods for adjusting the outer clamping ineinber.

6. win a device or" the class described, the combination of a cross tie composed oil spaced rods, and a head rigid with the rods and having upper and lower jaws, said head being also provided with an outwardly ei;- tending rail supporting portion located at an intermediate point between the jaws, an outer clamping ineinber having upper and lower jaws and provided with an intermediate opening to receive the rail-supporting portion and the terminals oi the rods, and means niounted on the rods for securing the outer clainping ineinber to the cross tie.

7. in a device ol' the class described, the combination oi a cross tie coinposed oi' spaced rods having threaded terminals, and clainping heads rigid with the rods and terminating short oi' the ends thereoiI and provided with upper and lower jaws, outer clamping ineinbers having upper and lower jaws to cooperate with the heads, and nuts inounted on the ends ci the rods 'for securing the outer clainping ineinbers to the cross tie.

S. in a device oi the class described, a cross tie including spaced. rods of a length to extend across a track, and rail clamps coinposed oi inner clamping ineinbers rigid with said spaced rods near the ends thereof, and outer clamping rneinbers adjustably inounted on the ends ol the rods beyond the inner clamping nienibers.

ln testimony, that l claini the foregoing as inv own, l have hereto affixed inv signature in the presence of two witnesses.
