Specification of Letters Patent.

Application filed April 28, 1907. Serial Ko. 3f.70,407.

citizen of the United States, residing at Granite, in-the county of Madison and State. oflillinois, have invent-ed certain new and "useful Improvements in Car-Truck Side;

Frames and Journal-Boxes, of which the Q is an nd elevation of the side-frame and journal box; Fig. 12 is a perspective view of,

following is a specification.

My present Invention concerns railway 1Q cat-truck side-frames and journal boxes, and

-its object is to form on the frame and 1n tegral therewith projections or fingers to co act with both the journal--bearing and its wedge-t0 prevent their displacement, whereby thethrusts on these parts by theaxle are transmitted directly to the side-frame rather H than to similar lu' s or projections on the ournal box itself which are much more likely to be brolren ofi'.

Preferably, though notnecessarily, each more projections adapted to prevent shift-.

. -ing of the journal bearing.

, On the accompanying drawings forming a part of this specification I have illustrated several desirable embodiments of my inven tion.

Figure 1 is a perspective view of an end portion of a car-truck side-frame illustrating one embodiment of my invention; Fig.

2 isa perspective vic'" a journal box or casing which maybe used in connection with the form of side-frame shown in Fig. 1; Fig. 3 is a partial side elevation and partial section of the side-frame and journal box shown in Figs. 1 and 2; F ig. 4 is a cross section transverse to the side-frame illus trating the coiiperation betweenthe various parts of the structure; Fig; 5 is a bottom plan view of the journal box and side-frame, the two being fastened together; Fig. 6 is a perspective view of afragment of a. modified form of side-frame embodying my invention; Fig. 7 is a perspective vlew of a. journal box or casing adapted to be fastened to and cooperate with the side-frame shown in 6; Fig.8 is a side elevation of the end portion of the side-frame and illustrates the j onrnal box in transversesection; Fig. 9 is a vertical section through the side-frame and journal box or casing trans\-'erse to the side-frame; Fig. 10 is a to plan of the united sideirame and journa box; Fig. 11

theside-frame; Fig. 14 is a perspective view of a journal box or easing adapted to be used in connection with the side-frame shown in Figs. 12 and 13; Fig. 15 is a side elevation of the side-frame and journal box; Fig. 16 is a section similar to those of Figs. 4, and 9; Fig. 17 is a top plan view of the side-frame and journal box; and Fig. 18 is an end view of the same parts.

Referring to the form of side-frame shown. in Figs. 1, 3, 4 and 5, it will be noted that the cast metal frame 20 has a'top T shapcd compression"member or chord 21 and a similarly shaped but inverted tension bar or-anember 22. Preferably the sideand tension members being united and joined at the ends of the frame. At each end the frame has a flat horizontal plate portion 23 with apertures or holes 24. at its is equipped with a pair of downwardly-extending fingers or lugs 25. Extended I downwardly from the under face of this plate 23 and transversely thereof are a pair of pro ject-ions or stops .26, the inner edges of which are inclined or curved at 27 so as to form braces to assist in holding the projections in proper position. The outer edges of these projections 26 are substantially vertical and straight. In order to strengthen the parts a web 28 is provided to connect inner face of the adjacent projection 26, while a bracket 29 integral with the frame is supplied and connects the outer face of the end projection 26 with the under surface of the plate 23, the edge of this bracket or'brace 29 being curved, as is clearly shown in Figs. 1 and 3.

or casing illustrated Fig. 2 to be used is a similar View toward the inner side of frame is cast in one piece, th: compression I have invented a form of journal box Patented M:..r. 14, 1911.

corners, and in addition at its outer edge it the outer face of the tension bar 22 with the in connection with the typeof side-frame shown in Fig. 1, the box having a round ed bottom wall 31 and an open top. At its fronttop end the box or casing has a horizontal wall 32, grooves 33 in the side walls beneath the partial cover 32 being provided to acconnnoda-te the front portion of plate 23 of the side-frame. Extended laterally from each side wall of the box I provide a pair of horizontal ears 34 each supplied with an aperture 35, these apertures when the box is in position on the side-fcame being in alinement with the holes 24 of the frame. The inner end wall and the inner end portions of the side-walls arise somewhat above the top faces of ears 34, thereby providing the vertical shoulders 36 which when the box is attached to the frame lie against the inner-edge of plate 23. A vertical slot 37 is provided in the inner side wall of the box and is adapted to accommodate and receive the web 28. The

upper portion of the outer side wall of the box opposite .slot 37 is bowed outwardly at 38 so as to house the brace or bracket 29 when the box is in position.

Bolts 39 passing through the apertures of ears 34 and the holes 24 of the horizontal plate 23 are adapted to securely maintain the journalbox or casing in position on the side-frame, and when in such position the front part of the plate 23 fits in the slots ;33, the fingers or lugs 25 are located within the journal box, the projections or stops 26 lie adjacent to the inner surfaces of the side walls of the journal box and are disposed within its hollow interior, the shoulders 36 abut against or lie adjacent to the inner edge of plate and the plate 23 forms the cover or top wall for the journal box. In order to exclude dust, dirt or other foreign substances a suitable packing may be used at the joints if desired. the journal 40 of the car axle 41 is of somewhat less diameter than the axle, thereby providing the shoulders 42 and.43 at its opposite ends. Resting on this journal is the usual bearing 44 which has laterallyprojecting or sidewise extended lugs 45 (see Fig. 5), which co-act with the outer faces or ed ges of projections 26 to prevent inward shifting of the bearing and axle. As is customafy. the'bearing at its inner'end has an upstandingflange 46 overlapping the inner end of the journal wedge 47. the outer end of which abuts against the fingers or lugs 25 to prevent outward shifting or movement of the wedge, bearing and axle. If the axle 41 tends to shift, inwardly the shoulder 43 strikes the outer end ofbearing 44 and tends to thrust the latter in the same direction, butowing to the coiiperation be; tween the ears 45 and the projections 26 inward movement of both parts is prevented.

On the other hand, if the axle tends to shift As is customary,

outwardly the shoulder 42 strikes the inner end of the bearing 44, andthe flange 46, because of its engagement with the corresponding end of wedge 47, transmits the thrust through the wedge to the lugs or fingers 25 integral with the side-frame which prevent movement in an outward direction of all the parts. 7

Since the fingers 25 and the projections 26 are integral and unitary withthe cast metal side-frame all the strains and thrusts of the axle are transmitted directly to the side-frame and not indirectly to the frame through the journal box as is the case whenthe box is separate from the side-frame and has the corresponding lugs and projections on its inner surfaces and integral therewith. It will be observed also that the journal box or casing 30 may be readily removed from the side frame by removing the nuts from the bolts 39. It has been proposed heretofore to make the entire journal box integral with the side-frame, andtheoretieally this is a good construction but practically it is almost impossible to produce castings of this character which are not defective. -By my improved construction of side frame and journal box I- am enabled to secure the advantages of the unitary sideframe and box and yet have a structure the parts of which may be cast without difii culty.

In Figs. 6 to 11 inclusiveI have illustrated another form of side-frame and jour-z tend to the extreme end of the frame but is provided with curved tapered outwardlyextended parallel flanges 51 and 52 which connect the outer face of the web with the extreme end of the frame. These flanges 51 and 52, in connection with the vertical side plate portions of the terminal portions of the side-frame of which they form extensions, comprise side walls which are recessed at their lower parts and rovided at the top of the recess with a fiat orizontal plate 53 which extends both inwardly and outwardly from the side walls of the frame. These walls at their lower ends are connected by the

horizontal webs

54 and 55, each of which has an aperture 56 and 57 respectively. Connecting the adjacent ends of the

parts

54 and 55, and extended inwardly beyond the inner side wall of the frame, are two transverse webs or projections 58 and '59, the outer edges of thesewalls or prorecesses 60. Extended downwardly from or 131'- portion of its -to% as is shownin ig. 14, hinges being pro-' 'near the outer edge of plate 53 are apairof depending fingsor lugs 61., T i I The'hox 62 which is adapted to be used in connection with the side-frame shown in tl isillustrated in Fig. 7 .andihas a ;.1.curved lower wall 63 and an open top, the shoulders; 6d: and 65 at the ends of the top opening being adapted to overlap the inner and outer edges of plate 53 when the box is in-position. Each side wall of the box has T avertical-slot 65 extended therethrough, and at its base has asidewise-extended aper- -tured earfor shelf 67, ,the.holes through which are spaced apart thesa'me distance between the apertures 56 of the side- .ifrhe has or is when shelle j the side-frairi'by-means' of bolts 68 passed through the holes; 56 and =57 and theapere 13 tures of the cars- 67, as is'clearly illustrated in 8, theearslyingagainst the under faces'ofithe'webs or -walls 54 and as'isf 'clearly illustrated. When the box in this position theprojections 58 and 59 are 10 M 25 .catedinside-of the side walls of the journal box creasing, asisshowmin Fig. 10,-tlie 'slots aocommodatingxthe portions 'ofthe liran e between the recess 60 and the inner face of-thev-side-fian'ie. vFingers 61 are also 2 within'thejournal box, the plate 53 -.--:Eormin cover for the box, as is illustratedm F igQQ,- The coiiperation between axle,journal"bearing, wedge, fingers 61,

Vertical slots 84 are provided-in the side walls of the box, and

outwardly-extended from the outer face of each wall at the edges of this slot 84 are a pair or parallel

vertical ears

85 and 86, and

the top edges of the brackets-or ears 86 are "connected to the top edges of the side walls by fiat plates or sleeves 87, each aperturd at 88. When the box is applied to the frame, bolts 89 are passed through the

holes

78 and 88 to maintain it in position. The slots .84 accommodate the webs or braces 77 and the cars 85 and 86am located on ,op osite sides of these members 77, as is'clearly s iownin Figs. 15 and 17." The projections 7 6 are within the box asare also the fingers 75,

plate 73 forming a cover-for the top opening through the journal box. The cotiperation .of the internal parts is substantially the same asthat in the other forms of the device so that a further description is not necessary.

To. those skilled in "this art itfwill b obvious and apparent that many changes in the structural featfires of the parts shown: and described mav be made without departing from the substance and heart of my in vention.
