CAR-BOLSTER CHAFING-PLATE.

Specification of Letters Patent.

Patented May 30, 1911.

Application led November v7, 1910. Serial No. 591,089.

. attached to the sides of a car truck-bolster for engagement with similar plates or strips on the inner faces of the transverse members or transoms of the trucl frame, between which the bolster rides, and jlhas'for its object to maintain a normal clearancevbetween the engaging plates and thereby reduce the side play of the bolster at all times/" It consists in features of novelty a's hereinafter described and claimed, ,reference being had to the accompanyingdrawing forming part of this specification, whereon,

Figure 1, is a vertical transverse section through a car truck-bolster and one of the adjacent transverse members or transoms of the truck frame, on line 1, 1, in Fig. 2, showing the application of my improved chafingplate thereto; Fig. 2, a horizontal section thereof on line 2, v2, in FigQl; Fig'. 3, a similar ,View to ig. 1, showing a modification of my invention; Fig. 4, a top plan thereof, and Fig. 5, a similar View ofl'the bolster to Fig. 1, showing a modified means of attaching the charting-plate thereto.

Like letters and numerals of reference tylenote like parts in the respective figures",

Referringl to Figs. 1, and 2/a represents,

a car truck-bolster, and b a transom of the truck frame adjacent to the bolster (i, the bolster a and transom b in the present case being preferably, composd of cast steel, but may be of the ordinary, (fr any suitable material and construction.

c is my improved chalingp'late which in the present case is attached toione side of the bolster a as hereinafter more particularly described. The chafing-plate c is preferably Wedge-shaped, having its outer 'ace vertically arranged aiid ada ited' for sliding contact Withvthe chafng-piate c which is riveted to the side of the transom b in theI usual manner and may be either of the ordinary description as shown, or similar 1n construction to the charting-plate c .as desired.

'The inner side of the chafing-plate c is inclined upward and rearwardly from the bottom in the direction of the bolster a and is preferably, formed with a series of trianguiar (or other suitably shaped) teeth'l, which preferably, extend entirely across the plate c and are adapted to engage wit-h similarly shaped teeth 1 formed on, and in the present case integral with the side wall 2 of the bolster a, the toothed portion 1 of the side wall 2 being faeially inclined correspondingly to the inner side of the plate c. Through the @hating-plate c at rightl angles to its outer face, and through the inclilied toothed portionV 1 of the side wall 2 of the bolster a are passed preferably, two

arallel horizontally arranged bolts 3 having their heads 3 countersunk in the outer face of thje plate c and their nuts 3 adapted to be tightened against the inner face of the side wall 2, the openings 4 for the bolts 3 being vertically slotted above and below the bolts 3 as seen in Fig. 1.

By this construction, the chang-plate c is securely attached to the bolster a in an desired position relatively to its correspon ing plate c on the transom b, and when in service, owing to wear or other cause, the play between the chafinglates c, c', becomes excessive, on loosening the bolts 3 and disengaging the charting-plate c from the teeth 1 on the side of the bolster a, the chafiiig-plate c can be lowered along the inclined toothed )ortion l of the bolster a and thereby moved forward or outward from the latter until the normal play or distance between the plate `o' and c is restored, when the chatting-plate c vis rengaged with the teeth 1 and the bolts 3 (adjustable in their slots 4) re-tightened.

ln tho iiimlfcation of my invention shown iii Figs; 3 and 4, the charting-plate which is vertically arranged at, and clear of the side of the bolster a', is formed preferably, by the dependent leg 5 ot' an inverted L-shaped bracket d, having its otherleg 5horizontally arranged and overlapping the top of the bolster a', the leg 5 being formed on its underside with a series of teeth 6 which are similar to the teeth l in Fig. 1 and arranged at right angles to the chafing-plate 5 for engagement with similar teeth 6 formed on the top of the bolster a toV which the bracket (l is securely attached by preferably, two parallel bolts 7 which pass through slotted openings 8 in the leg 5 of the bracket d, and

through the top Wall 9 of the bolster a against the inner face vof which they are tightened by their nuts 7.

On loosening the bolts 7 and disengaging the teeth 6 of the bracket Z from the teeth 6 of the bolster a, the bracket d with the chafingplate 5 may be moved forwardly from, or rearwardly to, the bolster af according to the required play between the plate 5 and the corresponding chafing-plate on the transom b of the truck frame, when the teeth 6 are rengaged with. ythe teeth G and t-he bracket d' in. theadjusted position of the plate 5 secured to the bolster a by re-tightening the nuts 7 of the bolts 7.

4For resisting \the rearward springing of "the dialing-plate 5 when engaged by the transom chaing-plate l0, I preferably use a setscren- 11 lyvhich isthreaded through the sidewall 1,2 vof the bolster a and butts at its outer end against the inner side of the plate 35, the sereni4 11 being operated from thel inside of thc bolster a as shown.

It is obvious that the slotted openings 4 for the'bolts 3 in Figs. l and 2, and for the l slotted openings 8 for the bolts 7 in Figs. 3 and-4`, may be formed through the chatingplate c, andthe top Walll 9 of the bolster ct', respectively, in lieu of through the side Wall 2 of the bolster a and horizontal leg 5 of the bracket d. v In themodification of my invention seen in Fig. 5, the inclined toothed portion l for engagement by the teeth 1 of the chafingplatee, is made separate from, and adapted to bear against the side Wall 2 of the bolster a, the toothed portion 1 being formed on its rear side with a stud 13' which engages in a corresponding hole 13 through the side wall 2, the slotted openings 4 for the bolts 3 in this case being extended through the inclined portion l as shown.

What I claim as my invention and desire to secure by Letters Patent is 1.` The combination with a truck member, of a chating plate mounted on said member "and adjustable toward and away from the side face of'said member the meeting faces of which chaiing plate and member have interlocking engagement and meansfor rigidly fixing the ohaiing plate to the bolster in its adjusted position.

2. The combination with a truck member, of a chafing plate mounted on said member for adjustmenttoward and away from the side faces of said member, and interlocking teeth on the meeting faces of the chafing plate and truck member.

3. The combination With a truck member, of a chafing plate mounted onl the member, for horizontal adjustment toward and away. from the side faces of said member, and corl responding corrugations formed on the Imeeting faces of the truck member and the chang plate.

4. In a car truck, a eliating plate having ribs formed on its inner face, which chal-ing plate is horizontally adjustable toward and aWay from the side face of said chamber, and means whereby said chating plate is rigidly fixed to a truck member Withthe ribs against the face of said member.

5. A car bolster chang-plate having teeth adapted -to engage teeth on the bolster, and means for releasing the said plate from, and. for adjustably fixing it in, the engaged position of the said teeth, to the-said bolster.

6. A ear bolster ehaiing-plate having its outer face vertical and its inner side inclined thereto, teeth on the said side, a member on the bolster havingits outer tace inclined correspondingly to the said side, teeth on the said member adapted forengagement by the teeth on the said side, and means for releasing the said plate from and for adjustably fixing it in, the engaged position of the said teeth to the said member and bolster.

7. The combination With a truck bolster having a portion of one of its faces provided with corrugations, a ehaiing plate applied to the corrugated portion of said bolster and means for rigidly fixing t-he chaing plate to said bolster.
