to which it appertains tolnake and use the same. a

llhis invention relates to improvements in appliances tor railroads, particularly those adapted to prevent the spreading of the rails of railroad tracks. i

The principal object of the invention is to provide a very simply constinctedrail clamp and brace whichwill rigidly hold the track rails in their proper'spaced relation.

l-ln additional object is to provide a d vice to be applied tothe meeting ends of a pair of rails for holdingthe same against shifting, and thus maintaining their tread portions in the same plane at all times.

Still another object is to provide a brace bar having means torholding the nuts and bolts which look the Ineetingends of a pair of rails, against rotation.

With these and many other objects in view, the invention resides in the novel tea tur s of construction, and the coml'iination and arrangement of parts which will be hereinafter more particularly described and claimed and shown in the drawings wherein:

Figure 1 represents a transverse section through a pair of rails showing the improved brace bar applied thereto lhig. :5 is an end view of one of the brace bars showing a portion of the meeting ends of a pair ofrails in side elevation;

and secured to the usual ties T. In Figs. 2 end d, the meeting ends of a pair of rails R are shown secured together by means oi ordinary fish plates F through which and the webs W extend bolts 1 the ends thereof be ing threaded andprovided with nuts 2.

this of the objects of the invention is to provide a track gage and rail brace, and in the drawing this is shown consisting OIE a relatively thin brace bar which extends transversely otthe rails and in engagement with their-bases Any numberet these braces may beprovided at suitable points on the track, and in each instance they are constructed substantially similar to the one illustrated. The bar 8 projects a considerable distance on each side of the rails lit and it and has a pair of seats therein formed by recesses 4, said recesses being spaced apart the distance which it is desired to dispose the rails apart.

The recesses dare suthciently deep to receive the base flanges of the rails, the in nor wall 5 of one being upright, while the inner wall 5 of the other recess slightly overhangs the bottom thereof. lhe outer walls of both recesses overhang the bottoms of said recesses as shown at 6, thus toriningin etlect undercutportions in which the outer base flanges of the rails are dis posed. The ends of the portions 6 engage the webs of the rails or the fish plates li The portions 6 further have reinforcing heads 7 termed integrally with the tops thereof torengagement with the webs and fish nlates of the rails. i

The portions 6 and the heads 7 securely hold the rails against outward movement and thus prevent their spreading. the inward movement of the rails being prevented by the clamping niembersin the form of the plates 8 and 8, The plate 8 hasa dependingportion to provide a shoulder 9 for engagement with the upright wall 5 of one of the recesses. while the plate8"has an inclined'lower face. as shown. Both plates are provided with reinforcing heads substantially similar to the heads 7 and adapted to engage the inner side of the webs of the rails or the inner fish plates. The bottom of the depending portion which forms the shoulder 9 is shaped to lit the inner base flange of the rail It. Extending through the plates 8 and 8 and the brace bar 3 are bolts 111m vided with nuts 12 to hold said rails against lateral movement and also to prevent them from being raised from their recesses.

In order to prevent rotation of the bolts and nuts 1 and 2 due to the continuous vibration of the rails caused by the passage of rolling stock thereover, the reinforcing heads 7 and 10 are utilized as nut locks. From Figs. 2 and 3 it will be seen that each of the heads 7 and 10 has substantially parallel upright sides 13 and that they are of a width approximately the distance between the adjacent sides of the innermost pair of nuts 2. r

In assembling the device to the rails, the meeting ends of the rails It are first inserted longitudinally in the proper recesses before said meeting ends are joined together by the fish plates and bolts, these latter plates being then connected to the rails, and the plate-8 is then clamped in place. The rails R are thus positioned so that the adjacent head 7 has its upright sides disposed between the heads of the inner pair of bolts, and engaged with the same. The nuts on the free ends of the inner pair of bolts are likewise engaged by the adjacent heads 10 on the plate 8. This obviously efiectively prevents rotation of these bolts and nuts.

The rail R must necessarily be tipped or canted slightly sidewise when placing it in position in the other recess. The plate 8 being removed when this is done is then clamped in place.

By having the inner wall 5 of one of the recesses 4 overhanging the bottom of this recess, the meeting ends of the rails It are firmly clamped in place so that the tread portions of the same are maintained at all times in the same plane. This obviously prevents the customary uneven jarring of the rolling stock and noise as it passes from one rail section to another.

This device may be very inexpensively manufacturedand readily applied to the track where needed. It is designed to be used in addition to the ordinary ties or sleepers, preferably only at the joints in the rails. The brace bar 3 may be made rather thin, thus economizing in the amount of material used without sacrificing its strength to any'great extent.

I claim j 1. A device of the class described com- Copies of this patent may be obtained for prising a relatively thin brace bar disposed beneath a pair of rails, said bar having a pair of spaced recesses therein, the inner wall of one of said recesses being upright, the inner wall of the other recess and outer walls of both recesses overhanging the bottoms thereof for engagement; with the base flanges of the rails, heads formed integrally with the overhanging outer walls for engagement with the webs of said rails, plates detachably secured to said bar adjacent the inner sides of said rails, one of said plates having a depending shoulder for engagement with the upright inner wall of one of said recesses, and heads formed integrally with said plates for contact with the inner sides of said rails.

2. The combination with a plurality of rails, fish plates disposed on each side of the meeting ends of a pair of said rails, bolts extending through the fish plates and the webs of the pair of rails, and nuts on the ends of said bolts, of a relatively thin brace bar disposed beneath one of said rails, and the meeting ends of said pair of rails, said bar having spaced recesses to receive the base flanges of said rails, the inner wall of one of therecesses being upright, the inner wall of the other recess and the outer walls of both recesses overhanging the bottoms thereof for engagement with the base flanges of said rails, heads formed integrally with said overhanging outer walls, plates detachably secured to said bar adjacent the inner sides of said rails, one of said plates having a depending shoulder for engagement with the upright inner wall of one of said recesses, and heads formed integrally with said plates for contact with the inner sides of said rails, all of said heads being of a width substantially equal to the distance between the inner pair of nuts, the head on one of said plates being disposed between said inner pair of nuts, one of the outer heads being disposed between the bolt heads of the inner pair of bolts to prevent rotation of the bolts and nuts.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
