Patented Oct. 22, 1929 PATENT OFFICE JOHN G. MUELLER, F DAYTON, OHIO RAIL BRAGE Application filed August 2, 1928.

This invention relates to a new and improved form of rail braces and clamps there for, adapted to be attached to railway tracks.

It is the object oi. this invention toprovide rail clamps and cooperating rail braces,

which are adaptedtobe attached to the lower flanges of the railsand to engage the rails in such a way as to prevent spreading and turning of therrails.

It is also an object of this invention to provide a device of this class, in which the parts are few and simple, and easily applied and removedtromengagement with the rails.

It is a further object of this invention to l5 providerail clamps and braces therewith to securely hold therails in place and prevent any tilting of the rails, due to pressure 011 a curve, or. otherwise.

It is a turther object of this invention to 2 provide a rail braceand clamp in which the headof the ,rail is braced against turning,

thereby preventing the base flange of the rail from eating into the tie and causing it to weara-way and to generally deteriorate. By

535 means otholdingthe rail in upright position the flifeof the :tie is preserved, and it is more i or less prevented from rotting, due to the fact that the rail is not permitted to eat into it at the edge of the base-flange.

In the accompanying drawings is shown one preferred embodiment of this invention, which is used merely by way of illustration; it is not intended =1tOSl1O\V more than thepreferr ed form.

Referring to the drawings:

Figure 1 is a cross section of a railroad track with theclamping device applied to the lower flanges ot' the rails, and the bracing means engaging under the head of the rails. 1

Figure 2 is a longitudinal section showing one rail with the clamping and bracing means attached thereto.

Numeral 1 is used to designatethe rails to be found in conventional railroad tracks.

The numeral 2 represents the tie-rod, which has on each end thereof a threaded section, indicatedbythe numeral 3,adapted to receive the clam sing and bracing devices hereinafter described The clamping devices used. on. the inside Serial No. 297,046.

and the outside lower flange of each rail are similar as far as the clamping features are concerned, and the description of one will apply to the other. The clamping member for each rail is composed essentially of two parts, one to engage the outer lower tiangeand the other to engage the innerlower flange of the rail oi a railroad track. Each part is similarly constructed and similarly operated.

The numeral. 4 representsa clamping sleeve, which has extending therefrom to engage the upper surface of the lower flange of a rail, a hook member 5. Passing through the sleeve member a is a hole or opening,indicated by the numeral 6, through which the tie-rod passes.

Just beneath the hook member 5, a clamping sleeve is provided with an inclined surface that has a web member, indicatedby the nun eral 7, and provides a triangular shaped space between the sleeve member and the lower part of the base of the rail. In this triangular space there is a wedging sleeve, indicated by the numeral 8, which 'has therethrough an opening 10 in alignment with the opening 6 in the clamping sleeve.

The upper surface of the wedging sleeve is fiat and adapted to engage with the under surtace of the rail, with the exception of lip member 9 projecting up from the wedging sleeve and adapted to engage the outer surface of the lower flange of each rail. The opening 6 through the clamping sleeve is oval in shape to permit both a longitudinal and vertical movement of the sleeve in regard to the tie-rod 2.

On the wedging sleeve 8 there is a groove 11 coacting and fitting over the wedging member so that the clamping sleeve has a sliding movement in regard to the wedging sleeve.

The foregoing description applies to the clamping means for either side of the rail, and as far as this clamping means is concerned, each clamp is identical in structure.- But the outside clamping member has extending from the sleeve 4 a downwardly sloping member, indicated by the numeral 12, which has an inclined surface, indicated by the numeral 13, with a rib, indicated by pin the numeral 14, therein for a. purpose hereinafter described. The outside clamping member has also formed thereon a tongue, indicated by the numeral 15, and located on the afore-described part 5.

On the outer end and fitting over the tierod 2 there is a brace member 16 having a vertical part through which there is an el0ngated opening, indicated by the numeral 17, adapted to permit the brace member to have an up and down movement with regard to the tierod. On the lower part of the brace member there is an inclined surface with a groove therein, indicated by the numeral 18, adapted to receive the rib 14 and permit the movement of the brace member along the inclined surface 13.

Extending from the'brace member, in an angular direction therefrom, is an arm 19 adapted to engage under the head of the rail. In the surface of this arm, adjacent the rail, there is provided a groove, indicated by the numeral 20, in which the afore-described tongue 15. works.

For the purpose of clamping the parts in gripping relation with the rail and for the purpose of bringing the brace member .lnto cooperative relation with the clamping members and 1n engagement with the head of the rail, there are provided nuts 21 adapted to engage the screw threads 3 on the tie-rod to force the clamping members into engage- -ment with the base of the rail and the brace member in engagement with the head of the rail. The brace member 16, as shown clearly by Figure 2, may be placed in different posit-ions upon the clamping members and by bringing the nut 21 into engagement with the outer surface of the brace member, 1t is forced into contact with the clamping memhers, and by further movement of the nut the brace member will ride up the inclined surfaces, indicated by the numeral 13 and by the member 15, the tongue 15 being inclined at an angle similar to that of the face 13.

It will appear from this description, and

the relation of the parts, that the movement of the nut against the brace member tends to force the brace member along the dlrection of the tie-rod, and at the same time,

.upin the direction of the head of the rail.

Any movement of the nut which engages the brace member, tends to force the coactmg clamping members 1nto secure engagement with the base of the rail and to bring the arm 19 into secure bracing relation With the head of the rail.

A similar movement of the other nut member 21, engaging the 1ns1de gripping memhere will force the arm part 5 into firm en- 7 gagement with the upper part of the lower inside flange of the rail, while the wed mg'sleeve is brought into firm contact with the lower part of the same flange of the rail.

It will be seen from the foregoing description, taken in connection with the drawings, that there has been provided a device that will firmly and securely grip the rails to hold them in their proper positions, and at the same time, brace the rails against spreading tendencies due to the arm 19 engaging under the head of the rail.

I desire to comprehend within my invention such modifications as may be clearly embraced within my claims and the scope of my invention.

Having thus fully described my invention, what I claim is new and desire to secure by Letters Patent, is:

1. In a railway rail brace in combination with a tie rod, :1. wedging sleeve on said tie.

rod adapted to engage the bottom and edge of the base of a rail and remain stationary with regard to the rail after such engagement, and a clamping sleeve having an elongated hole therein to receive the tie rod for up and down movement thereon, and adapted in cooperation with the wedging sleeve to grip and hold flanges of different sizes, and a b ace member having an elongated hole associated with said sleeves and the tie rod to engage the head of the rail, said brace being adapted for longitudinal and vertical movement on said tie rod.

2. In a railway rail brace, the combination with a tie rod, of two hook members on said rod adapted to hear each on the outer portion of the rail base, and a single brace member at one end only of the rod adapted to bear against one hook member and against the head of the rail, and means on the rod to draw the several parts together to cause a clamping action.

3. In a railway rail brace, the combination with a tie rod, of three hook members on the rod, one to clamp the outer portion only of one rail and the other two to clamp both portions of the base of the adjacent rail, and a single brace member at one end only of the rod and adapted to bear against one hook member and the head of the rail, and means on the rod to draw the several parts together to effect a clamping action.

4. In a railway brace, the combination with a tie rod, of two hook members mounted thereon, one bearing on the outer portion only of one rail base and the other on the outer portion only of the other rail base, and two brace members on the rod and each bearing against its adjacent hook member and against the head of the rail, and means on the rod to draw the several parts together to cause a clamping action.

5. In a railway rail brace, the combination with a tie rod, of two hook members thereon to clamp the base of one rail, two other hook members on the rod to clamp the base of the other rail, and a single brace member on the rod at one end, bearing against the adjacent hook member and the rail head, and means on the rod to draw the several parts into clamping action.

(3. In a railway rail brace, the combination With a tie rod, of two hook members thereon to clamp the base of one rail, tWo other hook members on the rod to clamp the base of the other rail, and a single brace member on the rod at each end thereof, each brace member bearing against the adjacent hook member and the outer side of a rail head and mounted on the rod for lateral movement relatively to the rod, and means on the rod to draw the several parts into clamping action.

In testimony whereof, I atfix my signature.

JOHN G. MUELLER.
