Specification of Letters Patent.

Patented Mar. 1, A1921.

Application filed April 13, 1920. Serial No. 373,523.

- at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Rail-Braces, of which the following is a specication.

This invention relates to rail braces. The objectof the invention is to provide a device of this class for use against one side of a rail for adjustably laterally positioning it, and for rigidly securing it in position after wear has taken place between the rod and brace itself, and parts against which .the brace bears, the device being especially ap- .plicable to rails at and adjacent to.switch points whose lateral movement to and from the unsupported side of the rail render the use of spikes or other securing devices imractical also on guard rails or on rails on eavy curves.

The invention consists in a device of this class in which the rail brace block proper,

moves only longitudinally of the base plate on whichit is usually mounted, thus insuring effective action of the device in all posltions .of adjustment, in such a device which can be easily and cheaply made, which is satisfactory in operation, and not readily liable to get out of order, and particularly in many features and details of construction hereafter more fully set forth in the specification and claims. y

Referring to the drawings in which similar numerals represent the same parts ,throughout the several views,-

Figure 1 is a plan view of mechanism illustrating this invention in its. preferred The upper surface of this plate 10 in theV designhere shown, .is provided with a recess of substantial depth having one wall 16 a vainst which the edge 18 of one rail flange a a uts, the bottom surface 20 on which all the essential parts of the device rest and an opposite wall 22 against which bearing block 24 rests. This block 24 rises a substantial distance abovethe top of plate 10 to 'provide a vertical bearing face 26 extending 'across the plate 10 at substahtially right angles thereto. Bearing block 24 is in the case here illustrated made separable from the plate .10 and secured in place by suitable rivets 28, but these details are wholly unessential.

Between rail 12 and face 26 of bearing block 24 are located two vry essential members entering in thisinvention, viz., a brace block 30 and a wedge 32, interitting together on the angular line 34 which is diagonal to'. the center line of the rail 10 and to the bearing face 26. Brace block 30 is secured against movement transversely of the plate 10 by two different mechanisms. The first, preferable, but not essential is the downwardly turned lips or ianges 36 embracing opposite side edges of the plate; the second is the bolts 38 or the like extending rigidly upward from the plate 10 and entering elongated slots 40 formed in the member 30 so constructedas shown that, whenthese bolts are loosened the block 30 canbc moved ,transversely ofthe rail and longitudinally of the plate ,10, but not otherwise. These bolts 38 or the like, when-tight enedperform the additional function of detachably securing' the 4block x 30 against movement in any direction.

In the particular case here illustrated, the

vbolts 38 are shown as having countersunk wedge 32 it has another inclined surface 46,

4which as shown, clearsy the surface 20 of 48 in a counterclockwise direction to force' the surface 42 of the block-onto the rail ange 44 and thus clamp the rail to the plate bo1ts38 move.

' 50 60 of plate 10 vor brace bloc 60 consequent '.10 38, descri ed in the last paragraph, the

wedge 32 is also cla-n ipedv in fixed position. The smaller end of the wedge 32 is also provided with a top flange 54 extending over thev adjacent portion ofthe brace block 15 and parallel to the flange 52. Through this flange' 54 an'd the opposlte rtion of flange 52 are a rowA of yregistering 'oles 56 adapted to be selectively enteedbycotter' pin 58 adapted to be` inserted,in the case .here A 20 illustrated, in the' last hole beyond the edge yof brace block 4I60 of plate 10 and the e.

30 after thewedge'32 has been driven upwardas .viewed 1n Fig.. 1 to place tol hold the wedge 32 in positlongeven shouldthe The vplane ofconta'ct between the vertical :face of member 52 which bears on the vertivc alfface ofgroove 'is'inclined inwardly on member `52', as shown in- Fi 2, so that au when the parts a'r'e locked toget er in wedging actionthe bearing block cannot tilt upward from point 48 and get out from under thewedge. m, In the operation of the device assume that 351 wearfhas .taken place betweenthe rail 12 andlthplate'lO along the linel -16 or wearv has taken place between-the brace itself and arts off'theA rail against which the Ibrace arsA and that adjustment has to be made.

' 40 The operator simply loosens the nuts on bolts -38 until it is possible` by hitting the lowenwedge 32 as viewed in Fi .'1 to drive said wedgev upward, a'srview in Fig. 1, whatever distancev may be ir uired :to move 45 both the block 30 and the ra' 12 tothe left as viewed" in Fig. 2 to the desired position. On reaching this position vthe operator tightens the bolts 38, and inserts thec'otter pin 58 in the last holeI 154 which is be ond the edgekl30.` In thls position the rail is firmly lclamped to the plate; the wedge isv firml clamped Vupon the plate, the wedge is held1 a inst retract` ing movement, 'even .on :the` astening pro,- 56 duced by the-)bolt being loosened, and both the wedge and block are in operating-position directly over .the late 10, thus insurin a direct transfer of a l strain upon the ral 12 vdirectly tothe bearinglmember 24 and l to the platel.
