CHARLES S. BANGHART, OF FLUSHING, NEW YORK, ASSIGNOR, BY MESNE ASSIGN- MENTS, TO N-W EQUIPMENT 60., INCL, OF NEW YORK, N. "5., A CORPQRATION OF NEW YORK.

CHECK-PLATE FOB, JOURNAL-BOXES.

T aZZ whom, it may concern Be it known that 1, CHARLES S. BANG- HART, a citizen of the United States, residing at Flushing, in the county of Queens, State of New York, have invented certain new and useful Improvements in Check- Plates for Journal-Boxes, of which the following is a Specification.

This invention relates to journals and journal-bearings such as are employed on railway cars.

The invention has reference more par-' The axle commonly has its end received in a journal-box for coaction with a journalbearing located in the box and the extreme end of the axle extending beyond the bearing is provided with a circumferential groove. This groove is adapted to receive and coact with a check-plate provided with wall adapted to fit in the groove. Also these journal-boxes have been commonly provided with vertically disposed ways to receive the edges of the check-plates. The check-plate as thus used has consisted of a metallic plate of rectangular shape having the central portion thereof cut away to the form of a semi-circle with parallel sides extending downwardly from the ends of the semi-circle. Such a plate could be passed over the end of an axle, its side edges sliding in the ways in the journal-box and its inner edge entering the circumferential roove near the end of the axle. I have found that by so shaping the check-plate that it will coact, not only with the ways in the journal-box and the circumferential groove in the axle, but also with the end of the axle, a construction is produced which possesses important advantageous features in that it reduces wear and lengthens the life of the box in various other ways.

In accordance with my improvement, a check-plate is made in the form of a single integral casting having the parts heretofore Specification of Letters Patent.

provided in check-plates of this character and also having a wall which is adapted to extend over a substantial portion or all of the end of the axle. Such a check-plate may be constructed by employing two parallel Walls one of which is partially cut away, the latter wall being adapted to have its edge enter the circumferential groove in the axle and the other wall being adapted to lie against the end of the axle, one of these walls being extended to form guides which move vertically in the ways formed on the interior Walls of the j ournal-box.

I have illustrated the preferred embodiment of my invention in the accompanying drawings, in which- Figure 1 is a central vertical section of a journal-box, an axle projecting into the box and the improved check-plate upon the end of the axle; Fig. 2 is a horizontal section through the lower portion of the jour nal-box, looking upwardly toward the axle and checleplate, and Fig. 3 is a view of the check-plate.

Referring to these drawings, 4 indicates a journal-box of the usual or any suitable construction, this having a detachable cover The axle is shown at 6, its end being reduced and extended into the journal-box 4. The axle coacts with a suitable journalbearing 7 located within the box 4: in the usual. manner. The axle 6 adjacent to its end is provided with a circumferential groove 8 for coaction with a check-plate. The journal-box 4: has ways 9 formed on the inner sides of the side walls thereof opposite the circumferential groove 8 in the axle 6 when the latter is in its normal position.

The check-plate herein shown coacts with the circumferential groove 8 inthe axle 6 and with the ways 9 on the side walls of the box t and also with the end of the axle 6. This check-plate is preferably a casting of brass or similar metal. It has two substantially parallel walls 10 and 11, the latter of which is in the form of a flat plate and is adapted to lie against the end of the axle 6. The wall 10 has the central portion thereof cut away, the upper portion of this cut away part being semi-circular as shown in Fig. 3. The wall 10 as thus cut away is of such width that the edge thereof about the central opening will fit into the circumferential groove 8 in the axle 6. The two walls 10 and 11 are integrally united by a connecting wall 12. The wall 10 at the center thereof extends downwardly from the connecting wall 12 a distance equal to the depth of the groove 8 in the axle. At the lateral edges of the check-plate, ribsor guides 13 are provided adapted to enter within the ways 9 so as to hold the check-plate against excessive movement in the direction of the axis of axle 6. Fig. 3 is a view of the check-plate looking at the inner side thereof. The wall 11 which is adapted to coact with the end of the'axle shows through the opening in the wall 10. The wall 10 is shown as cut away to-permit the axle 6 to projectthroughit, the upper portion of the opening in this wall 10 being semicircular and of a diameter 'equalto the diameter of axle 6 at thebottom of the groove 8. The wall 10 is thickened slightly adjacent to the opening therein and the raised surface on the'inner side of the check-plate formed by thus thickenin'g wall lOisfinished so as to provide a smooth surfacefor coaction with the axle'6. With this form of check-plate, a marked reduction is effected in the amount of wear on the button at the enclof the axle formed by the circumferential groove 8. It often happens that this button is worn off comand furthermore a substantial reduction is effected in the amount of breakage of checkplates when this construction is employed. Another advantage secured by the use of check-plates as herein shown and described isthat by the use of such plates the useful life of a journal-bearing is increased materially, this being due in part to thefactthat this form of check-plate: prevents dust and dirt'from working into the bearing and also prevents oil from working out-0f the bearingto a greater extent than the forms of check-plates heretofore commonly employed. 7

guideways, of a check-plate comprising two 7 substantially parallel, integrally connected walls, one of which has the central'portion thereof cut away to form a segmental flange seated within said groove in the axle and the other of which walls extends over and in contact with the end of the axle, said' first-named wall having laterally extending ribs seat-ed within saidgguidewaysin the j ournal-box, substantially as setforth. a 2. The combination "with a journal-box having vertical guideways on the inner sides ofthe wallsthereof and an axle having one end extending beyond the bearing in the box and provided with a circumferential groove adjacent its end, of a checkplate having laterally-extending edge-portions- V slidably seated within said guideways inthe journal-box, and having two substantially parallel integrally-connected walls, parallel to said edge-portions, one of which. walls comprises a fiat plate contacting the end of the axle, and the-other" of which comprises a semi-circular. flange seated within said groove in the axle, said walls being united by an integral connecting wall at the top thereof, substantially as set forth.
