T all who/m, it may concern:

Be it known that I, Linwoon A.. WALTERS, a citizen of the United States, residing at Alexandria, in the county of Alexandria and State of Virginia, have invented new and useful Improvements in Railway-Ties,

- of which the following is a specification.

proved tie showing r[his invention relates to improvements in railway ties and more particularly to a composition tie and a rail fastening means therefor.

'It is the object of this invention to providea railway tie composed of reinforced, concrete or cement of suc-h structure as to be able to resist the strain of heavy traffic without disintegrating and also tof protect the lower corners from crumbling or breaking off.

It is a further object of this invention to provide a rail fastening device that will secure the rails in place without the use of exposed nuts or bolts, prevent the spreading of the rails, form an additional support for the outer side of the rail and allow the rails to be placed and removed without the necessity of turning the rail from the perpendicular, and also transmit the outward angular strain upon the top of the rail at curves cause the device to more rmly grip the bei tern of the flange upon the inner side of the rail.

Whilev the preferred forms of this invention are illustrated upon the accompanying sheets of drawing yet it is to be understood.

that minor detail changes may be made therein without departing from the scope of this invention.

Figure 1 is a top plan view of this imthe reinforcing meinbers in dotted lines, and illustrating the left rail of the track indotted lines with the right rail in full lines as, engaged by this improved `fastening device. Fig. 2 is a transverse sectional view through the` tie taken at the end of the I beam reinforcing member. Fig. 3 is a longitudinal vertical sectional view taken through the center of the tie illustrating the reinforcing members in sideelevation. Fig. t is a central longitudinal vertical sectional view taken through this fastening device, showing the position of the rail in dotted lines. Fig. 5 is a view in end elevation of this device looking from the outer side of the track. Fig. 6 is a top plan view of this fastening device with the locking and rail reinforcing member re. moved. Fig. 7 is a perspective view of a.- spring shock absorbingV member. Fig. 8 is a top plan view illustrating the application of 4this imprfrved fastening device to' a wooden tie with parts broken away, and illustrating the left rail of the track in dotted lines with the right rail in full lines as engaged by this improved fastening device. Fig. 9 is a perspective view vof/'a modification of Fig. 7. Fig. l() is an enlarged top'plan view of the rail hook.

Ihe composition tie l as contemplated in this invention is of the usual dimensions of ties in common use by railroads and is formed of concret-e, cement, or any other plastic material that is the equivalent for this purpose.

The main reinforcing member is an I beam 2 arranged centrally in the tie preferably terminating -in line with the outer edge of the rail fastening device on each side of the track, and each end is supported by an inclined plate 3 bolted to the lower flange of the I beam resting and secured to an angle iron 4- forming the lower transverse edge of the end of the tie. By this construction not only is the molding of the tie simplified,

as the reinforcing member is properly positioned and held during the filling of the mold, but the lower edge of thetie is reinforced by the angle iron anchored to the reinforcement and insures a proper support of the tracks by the tie end.

Each end 5 of the I beam is arranged parallel and a slight dist-ance below the top of the tie l for supporting and securing a rail fastening base plate 6 preferably of galvanized iron which is bolted in place before the tie is molded. The ends of the I beam are then inclined downwardly to# ward the center to meet a horizontal central portion 7 of about equal length to the inclined portions 8 and substantially centrally located within the tie. The inclined portions S on each side are united by the rods 9 preferably two in number bolted or otherwise securedto the inclined portions and arranged on each side of the longitudinal cen-ter7 which are embedded below the upper surface of the rlhe base plates 6 for the fastening devices are preferably secured to the I beam by bolts passing through both upper and lower iangcs and surrounded by sleeves l0 FFCE. l,

iin

between the flanges. As the base platesV 6 are preferably flush with, or extend slightly the center of the tie with the upwardly inclined portions on eachside thereof termi-v nating in horizontal raill supporting por-l tions with the inclined portionsrconnected by tie rods forms in effect an'i'nverted trussy through which the weight upon the rails duringtratlic thereon is evenly transmitted from the ends throughout the entire body of the tie. y v

The improved rail fastening device designed for use with this composition tie comprises two spaced-apart securing plates 11 with their adjacent longitudinal sides 12 undercut to form a guide-way and engaging means for a rail engaging member 13 mounted to slide therein. The rail engagf ing member 13 is of substantially the same height as the securing plates 11 with 'its sides inclined to correspond with the undercut sides 12 of the securingfplates so that it can slide longitudinally therebetween but will be held against vertical movement. Une end of the rail'engaging member 13 is provided with a hook 14 upon its upper surface constructed and adapted to engage and hold the flange on one side of the rail and is provided with a transverse extension-14*1 on each side of the hook 14 having inclined inner sides and endsadapted to engage under cut sides of corresponding cutout portions oneach securing plate adjacent-thereto. The upper side of the other end of the rail engaging member 13 yis provided with an upstanding heel or abutment 15 adapted to pass through and above t-he securing plates 11.

' The farthersides ofthe securingplates 11 adjacent the tie end are provided with corresponding upstanding ears 16 each terminating in a perpendicular inner edge. A locking and rail reinforcing member 17 is removably secured between the ears 16 by a bolt 18` passing through the member and ears and secured in place by a cotter pin or mit 19. The'locking an'd'reinforcing member 17 is provided with a flat base 20 vadapted to rest upon the securing plates 11 and is shaped upon thev rail side 'to -follow the contour of the rail flange and web forming a shoulder 21 and rail web engaging portion 22 extending upward to the underside of the rail head with the opposite and outer side 23 inclined or 'curved downwardly yto the outer end of the base 20 to form a body of metal between the rail web andthe will engage the abutment 15 upon the outer end of the rail engaging 'member 13 and .by inserting the bolt 18 through the vears and locking member all parts of the fastening 'device will be held in operative position.

To absorb the shockl of'vibration caused by traliic upon the rails each securing plate 11 is preferably provided with two circular counter-sinks 24: arranged on each side of' the center of the position assumed by'the rail when in place, which are adapted to receive a spring shock absorbing member, illustrated as a split Washer 25, or the corrugated washer 26.

The securing plates 11 may be fastened l to the base plate 6 on-the composite tie by the heads ofthe bolts securing the base plate to the I` beam engaging in counter sinks in the securing plates.

Fig. -8 illustrates the application o f this fastening device to agwooden or other tie 1a in which the base plate 6a extends along theentire length of the tie and is secured thereto in any desired manner.

It is readily seen that no spikes are used p or exposed securing nuts employed for securing the device tothe tie or in operatively securing the parts of the device together Vwhich might work loose from vibration and cause the rails to spread or work loose from the fastening. The rails may be placed in position orremoved in a perpendicular line as the rail engaging member is movable transversely of the rail to clear its hook of the rail edges and the ears are perpendicular so that it is not necessary to turn the rail in order that its flanges may be engaged or released by the fastening device.

4As the locking. and rail reinforcing member is always on the outer side of the track the outward strain upon the rail on curves which tends to tilt .the rail outward is transmitted from the rail Web through the locking and reinforcing member to the abutment 15 upon the rail engaging member 13 and through the rail 'engaging member to the hook 14 on the inner side of the track.
