, RAIL-FASTENER FOR METAL TIES.

Application filed February 21, 1917'.

To all whom t may concern:

Be it known that I, FRED H. KRUPP, a citizen of the United States, residing at Northfield, in the county of Rice and State of Minnesota, have invented Certain new and useful Improvements in Rail-Fasteners for Metal Ties; and he does hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an extremely simple and highly efficient rail fastener for metal railway ties; and, to this end, it consists of the novel devices and combinations ofA devices hereinafter ,described and defined in the claims.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring. to the drawings:

Figure 1 is a fragmentary view showing in transverse section, one of the rails of a railway track secured to a metal tie by means of two of the improved fasteners;

Fig. 2 is a fragmentary view principally in side elevation with some parts broken away and some parts sectioned;

Fig. 3 is a plan view of the parts shown in Fig. 1;

Fig. 4c is a longitudinal section taken on the irregular line 1 4 of Fig. 1; and

Fig. 5 is a fragmentary plan view of the metal tie.

The numeral 6 indicates a metal railway tie of the I-beam type and having supported on its top horizontal flange one of the rails 7 of a railway track. AFormed in the top horizontal flange of the tie 6 and 'underlying each longitudinal edge of the base flange of the rail 7 is a pair of elongated aportures 8. These apertures 8 extend parallel with the web of the tie 6 and are located, one on each side of said web with their inner sides flush therewith. It is important to note that the longitudinal edges of the base flange of the rail 7 intersect the apertures 8 at their intermediate portions. Formed in the web of the tie 6, in substantially the same vertical plane with each pair of apertures 8, is an aperture 9. These apertures 9 are inclined upwardly and away from each other, as best shown in Fig. l.

The rail 7 is secured to the tie 6 by a pair Specification of Letters Patent.

of spikes 10 inserted, each through one of the apertures 8 of each pair thereof and with, their heads engaging the opposite longitudinal edge portions of said rail. The bodies of the spikes 10 extend through reetangular links 11, and one of these links vll'is mounted in each aperture 9 with freedom for endwise sliding movement transversely of the tie 6 and for bodily movement longitudinally thereof. By reference to Fig. 2, it will be noted that one side of the spike 10 is straight and bears directly against the web of the tie 6 andthe other side thereof is upwardly tapered and bears directly against the adjacent end of the link 11, which is correspondingly beveled. The two spikes 10 are placed in diagonally opposite apertures, so as to always bring their straight sides in direct contact with the web of the tie 6.

A wedge 12 is inserted through the other aperture 8 of each pair and through the respective link 11. The straight sides of the wedges 12 bear directly against opposite sides of the web of the tie 6 from the spikes 10 and their other sides are beveled downwardly. The inner faces of the adjacent ,ends of the links 11 are beveled in the same direction as the outer sides of the wedges 12, and have direct engagement therewith. Obviously, by driving the wedges 12 into the links 11, said links are moved lengthwise into direct frictional Contact with the spikes 11. The beveled surfaces of the links 11, which engage the upwardly tapered surfaces of the spikes 10, tend to draw said spikes downward and, at the same time, prevent the same from working upward. It will thus be seen that the heads of the spikes 10,v engaging the base flange of the rail 7,

hold said rail firmly in position on the tie 6.y

To prevent the wedges l2 from working loose under the vibration of the rail 7 and tie 6a flat key 13, having a laterally .bent end, is provided therefor. The bodies of the keys 13 extend between the wedges 12 and web of the tie 6, with their laterally bent ends extending intothe apertures 9, over the links 11, to thereby anchor said keys. After the wedges 12 are driven to place, the upwardly projecting ends of the keys 13 are upset over the tops thereof. It is, of course, understood that the keys 13 may be anchored in various different ways.

From :the .abovedescriptiom it is evident that the rail 7 -may be set to the proper gage of the track by adjusting the links l1 in the apertures 9.4 lt is also evident that each pair of links ll may be setdifferent distances apart to' properly space the spikes 10, in

order-that they may engage the base flanges v of rails of different weights, and hence having base flanges which vary in width. Outward lateral pressure on the rail 7 acting through the spikes lO'as levers, will tend A to twist the links 11 in horizontal planes and thereby cause the same'fto'frictionally engage 'the upper and lower surfaces of the apertures 9. yThis twisting of the links l1 will securely hold vthe same against lateralv sliding movement in the apertures 9 away` from "the rail 7. The upwardly inclined surfaces Vofthe apertures v9 will also greatly assist in preventing the vlinks lll from moving away frointhe rail 7, while at the same time they will tend to cause said links to move toward each other and hence keep the lheads ofthe spikes 10 in voverlapping engagement with the base 'liange of the rail 7. By reference to :the drawings it will be noted that lthe 'improved fastener will permit `shims to `be inserted between'the rail and tie which is of course highly important. y

That l .claim is: v

l. rlhe 'combination with a tie having a vertical web, and a rail supported on said tie, of a link seated in an aperture in the web of the tie with freedom for eiidwise movement longitudinally ofthe rail, a spike having itsb'ody `extending into said link and its head 'engaging the base flange of the rail, and a wedge insertedinto said link on the opposite -side of the web of the tie from the spike for holding the linkin engagement y with' the spike.

QQThe combination 'with a tie 'having la vertical'web, and a rail supported on said tie', of a Ilink. seated in an aperture in the ,web of .the tie with freedom for endwise movement longitudinally of the rail, a spike l having its body extending into ysaid link andits 'head engaging the base flange of the rail, a 'wedge inserted into said link on the opposite side of the web of l'the tie from the spike for holdinglthe link in engagement with-the spike vand a fkey for hold-ing ythe wedge 4against lifting movement.

The combination with a tie having a copies of 1-th'if'patentmay be l@mainte for vertical web, and a rail supponted on said tie, of av link seated in an aperture inthe web of the tie with freedom for endwise movenientlongitudinally of the rail, a spike having an upwardly `,tapered body extending into said link and kits head engaging the base i-ange of the rail, and a .wedge inserted into said link on the opposite side of the web of the tie from the spike.
