STOP FOR JOURNAL-BOXES.

Patented-Sept. 11,1906.

To all whom, it may concern.-

'a citizen of the United States of America, residing at McKeesport, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Stops for Journal-Boxes, of which the following is a'specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in journal-stops as used in journal-boxes for preventing the end thrusts of axles or shafts j ournaled in the boxes, also to receive the wear and tear of the axle or shaft within the boxes and protect the contents thereof. 1

The invention aims to provide a novel form of j ournal-stop which will wear a considerable period of time and may be renewed in part without dis osing of the entire sto In this connection have devised a journa stop particularly adapted to be used in connection with the j ournal-boxes of rollingstock, although the use of my improved jour nal-stop relative to a certain type of journalbox is arbitrary, my inventionnot residing in the location of the stop, but in the detail construction thereof, which will presently bedescribed and claimed.

Reference will now be had'to panying drawings, wherein like numerals of reference designate correspondin parts throughout the several views, in Whio Figure his a vertical sectional view of a conventional form of journal-box equipped with my improved journal-stop. Fig. 2 is a plan of the journal-box with the lid thereof removed. Fig. 3 is'a vertical longitudinal sectinal view of the box. Fig. 4 is a horizontal-sectional view taken on the line a: x of Fig. 3. Fig. 5 is a front elevation of the'box, illustrating my improved stop partly positioned therein. Fig. 6 is a similar view illustrating a stop as seated and in proper position relative to said box. Fig. 7 is aperspective view, partly in section, of my improved journahstop; and Fig. 8 is a'central longitu-- dinal sectional view of a journal-stop, illustion. In [the accompanying drawings Ihave' trating a slightly-modified formof construcillustrated the end of a conventional form ofaxle 1, having an axle-bearing 2, upon which the acco'mis mounted a conventional form of car-wheel 3. The contracted or spindle end 4 of the axle extendsinto a conventional form of 1ournal-box 5, which is supported by the framework 6 and is adapted to support a frame 7, which rests upon springs 8 8, mounted upon the top of the journal-box 5. The journal-box is provided with awontracted opening 9, which is normally closed by a spring-pressed lid 10 and a plate 11. The side walls 12 12 of the journal-box adjacent to the opening 9 are provided with outwardly extending lugs 14 14 and 15 15, forming parallel slots 16 17. The lugs 15 areprovided with upwardly-extending ribs 18, forming sockets 19 between the lug 15 and the rib 18 journal-stop 21, which is'clearly illustrated in Figs. 1, 5, to 7, inclusive. The stop consfs s ofa' strong and durable metallic foundationplate 22, the ends of which are provided at the upper and lower edges with re'arwardlyextending-bearing or su porting legs 23 23. while thefoundationate 22 is provided with an axle bearing of Babbitt metal or the like material 254.

In order that the Babbitt metal or a similar metal may be secured to'the foundationplate 22, I rovide the plate with outwardlyextending ugs 25, which are adapted to engage in the Babbitt metal 24 when the same is molded upon. the foundation-plate 22, thereby providing an extra rip for the Bab bitt metal besides the face 0 the foundationplate. In some. instances the foundationplate 22 may be provided with a plurality of o enin s 26, (see Fig.-8,) and when molding t e Ba bitt metal 24 upon the foundationplate 22 the metal may descend into the openings 26 and in this manner become fixed upon the foundation plate. Even with these two methods of securing the Babb tt metal upon the foundation-plate it is obvious that other means may be devised for acco'mplishing the same purpose. not care to confine myself to the manner of uniting the Babbitt metal with the foundation-plate. The formation of the Babbitt Therefore I do metal 24 upon the foundation-plate 22 is substantially rectangular in plan, and I provide the upper and lower edges of the Babbitt metal with enlargements 24 24 the object of which will presently be described.

After the ournal-bearing 27 has been placed in the journal-box upon the contracted or spindle end 4 of the axle ad the jourproved journal-stop is mounted in the journal-box to bear against the end of the contracted end or spindle 4 of the axle. In Fig. 5 of the drawings I have illustrated the position of the stop within the journal-box be fore it is seated, this position of the journal-.

stop being assumed when the stop is moved The bearing or supporting toward the axle. legs 23 of the stop pass within the'slots 16 and 17 until the Babbitt metal 24 engages the end-of the journal-bearing 2-7 and the axle 1, at which time it is forced downwardly, the legs 23 23 riding within the verticallydisposed slots 20 until said legs engage behind'the lugs 14 14 and Within the sockets 19 behind the lugs 15 15. tion, (see Fig. 6,) the Babbitt metal 24 is positioned between the ribs 18 18 andin engagement with the end of the contracted or spindle end 4 of the axle. The lugs 14 14 and 15 15 are adapted to prevent a rearward When in this posimovement of the journal-stop, it being only possible to remove the journal-stop by ele-, vating the same until the legs 23 23 register;

with the parallel slots 16 and 17; but whenf with this type of journal-box it is obvious d that it may be readily used in connection the stop is being used I- employ a key 29, which is mounted in an opening 30, forme in one of the side walls 12 of the j ournal-box, to engage upon the top of one of the legs 23 and prevent the ournal-stop from beingelevated until the key is removed.

Vfhen the journal-stop is in position Within g the journal-box, the formation of thelegs 23 23 relative to the foundation-plate -22 forms;

a transverse bridge structure or supporting the Babbitt metal, and as this metal receives the wear and tear from the axle occasioned; by endthrusts a certain resiliency main- 1 tained by the foundation-plate 22 on account;

of its idge-like structure will to a certain{ extent permit of the foundation-plate re-f ceding before breaking. a

By constructing the J manner above described the entire destrucournal-stops in the 1 tion of the stops incurred by sudden thrusts or blows which they receive is entirely eliminated, and by protecting the foundationplate with a softer material than the late I am enabled .to use the foundation-p ates a number of times by simply renewing the Babbitt metal which they carry. The enlargements 24 24" are rovided to insure a greater contacting s ace of the Babbitt metal with the end of the shaft than if they were not used, said enlargements tending to I lugs.

brace the contracted or spindle end 4 of the 6 5 bearing 27.

An important advantage derived from my invention is its adaptability to any type of journal-box which is reinforced by the lugs nal-bearing key 28 placed therein my -im-- 14 and 16, providing slots 16 and 17 on the side Walls of the box, whereby the journalstop can be properly supported therein. Throughout the description of the journalsto I have specifically described the use of Ba bitt metal inconnection with thestop; but I desire it to be understood that brass, bronze, or the like composition can be readily used. By the construction of my improved journal-stop, together with the box in which it is used, a large end-bearing surface is rovided for an axle and the stop is not depen ent on the action of the lid or journalliner, but may be removed or replaced with ease and without elevating the car, it only being necessary to sever the cotter-pins employed-to lock the journal-stops in position and to prevent persons from tampering with the same.

In the drawings accompanying this a pli-' cation I haveillustrated a conventional orm of journal-box, the detail construction of which will be familiar and ap arent to those skilled in the art of rolling-stoc construction, and while I have herein illustrated and described the stop as being used in connection with the journal boxes and bearings for shafts.

1. The combination with a journal-box 1 provided adjacent the forward end of its side walls with o positely disposed lugs arranged in pairs, an having ribs on sai side Walls spaced away from the lugs to form a groove between the ribs and the lugs ,and joining I with the lowermost air of lugs, of a stopplate provided at each end with a pair of feet adapted to engage in the grooves between the ribs and the lugs and seat against said 2.
