` SIDE FRAME.

.. specification of `Letters Patent i Pfntd May 17, 1921,

Application led March 25, 1920. Serial No.' 368,640.

To all whom t may concer/n.:

Be it known that I, HARRY E. Donna, a citizen of the United States, residing at St.r Louis, and State of Missouri, have invented certain new andA useful Improvements in Side Frames, of which the following'is a specification. This invention relates to side, frames, and particularly to side4 ,frames of the pedestal t e. f

y eretofore pedestal ltruck side frames have required a special journal box. Accordingly, such a side frame could not be used for replacements of arch bars or the standard type of frame, both of which useaster-Qar Builders j'ournal boxes. Therefore, one objectof this invention is to provide a simple and novel pedestal truck side frame which will accommodate Master Car Builders journal boxes in such a mane ner that parts of the side frame and journal boxes will coperate to prevent accidentally relative lateral movement.

Another object is to provide a truck side frame which may be detachably connected to a journal box in a manner to obviate the use of bolts and whereby an emergency fastening is formed should the truck be derailed or lifted from the track by any other part than the axles.

These and other objects are accomplished by means of the arrangement disclosed in the accompanying sheet of drawings, in which- Figure 1 is a fragmentary side elevation of a truck side frame embodying my inven tion, and shown in normal coperative position with a Master Car Builders standard .journal box;

' Fig. 2 is a fragmentary top the same arrangement an Fig. 3 is an end elevationof the same parts.

The various novel features of my inven- 4plan view of tion will be apparent from. the following description and the drawings, and, will'be particularly pointed out. in the appended .'claims.

Referring to the gures of the drawings,

it will be noted that I have provided a truck -These extending jaw portions 12 engage the side frame 10 having pedestal jaws 11, the lower ends of which terminate in laterallyr extending portions 12, which' extend toward each other lengthwise .of the side frame.

" provided my side frame sides of the Master Car Builders journal box 13 intermediate its ends and more par-l ticularly intermediate the vertical planes of the bolt lugs 14. vAs 1s apparent from the arrangement disclosed in the igures of the.

drawings, it would be impossible to apply the side frame to the journal box by a relative vertical movement'while the jaw extensions 12 arev intermediate the journal box bolt lugs 14. Accordingly, to apply the side frame tothe journal box when the latter is fixed on the journal, the side frame 10 is moved inwardly with respect to the journal box to a point where the relatively narrow jaw extensions l2 may pass vertically downwardly between the inner journal box bolt lugs v14 and the dust-guard housing 15.

With the side frame in this position, the

same may e lowered, permitting the' jaw extenslons 12 to pass vertically downwardly beyond the upper journal box bolt lugs 14,

whereupon fthe side frame may be moved vrelatively outwardly with respect to the journal boxv to take its normal loperating position. Q, f.

It will be noted that the side frame 10 is -provided with four housing lugs 16 which fit over the outside and embrace the four upper journal box bolt lugs 14.' lTAccordingly, when the ljournal box 13 and side frame have been moved relatively laterally to a point where the housing lugs 16 may assume the proper position with respect to the box lugs 14, the side frame 10A-is lo'wered into the position shown in Fig. 1 of the drawings to prevent relative lateral move-y vare provided with ralsed'portions 17 forming side shoulders or bearings 18. Ihave with oppositely arranged langles 19which are intermediate and connect t e lu 16 and which engage or embrace the'si es vof .the shoulders or bearings 18 of the journal box to assist in resisting the action on curves and also on nient between the side frame and journal roughnor Auneven track. Not only will the flanges 19 assist the lugs 16 in overcoming relative lateral movement between the journal box and the side frame, but the flanges 19 will strengthen the lugs and provide a more durable varrangement to overcome the severe service condltions.

It will be noted that the jaw extensions 12 are spaced from the housing lugs 16 vertically an amount to accommodate the box lugs 14 in applying the frame to and withdrawing the same from the journal box The pedestal jaw extensions 12 act as an emergency fastening for` maintaining the connection between the side frame and the journal box, and therefore the wheels and axles, in the event that the truck is derailed or is lifted from the track by any other part than the axles. No bolts or other fastenings -of any kind are used to hold the side frame in proper position other than the parts hereinabove specifically set forth; the housing lugs 16 embracing the sides of the journal box lugs 14, the flanges 19 embracing the journal box bearings 18, and the pedestal jaw extensions 12 bearing against the sides of the box for holding the same in proper relation to the side frame.. It will be understood that when it is desired to replacel a broken journal box, the same may be done by raising the side frame an amount to properly accommodate the upper journal box lugs 14 between the jaw extensions-12 and the housing lugs 16, whereupon the new journal box may be moved laterally inwardly to the point where the housing lugs 16 may move ldown over the journal box lugs 14 and the flanges 19 over the bearing portions 18.

It is my intention to cover all modications of the invention falling within the spirit and scope of the following claims.

I claim:

1. A pedestal truck side frame, including pedestal jaws havinportionspwhich embrace' bolt lugs of aster Car Builders journal boxes, and having associated portions connecting said other portions longitudinally and embracing bearings on said journal boxes normally, to prevent relative lateral movement between the I side frame and journal box. v

2. A truck side frame, including pedestal .jaws havingV portions which engage bolt lugs on Master Car Builders journal boxes, and having strengthening flanges connecting said portions which engage shoulder bearings on said journal boxes normally to prevent lateral movement between the side frame and journal box.

s 3. A pedestal truck side frame, including edestal jaws which embrace bolt lugs on aster Car Builders journal boxes, and

having means intermediate said portions which embrace side shoulder bearings on said journal boxes normally to prevent relative lateral movement between the side frame and journalbox, said pedestal jaws also having portions which embrace the sides of the journal `box between the bolt lugs thereof for assisting .in maintaining the operative position of said side frame and said journal box. I

4. A pedestal truck side frame having a plurality of lugs for embracing adjacent bolt lugs on Master Car Builders journal boxes, and havin flanges intermediate certain of said lugs igor embracing the shoulder portions on said journal boxes to prevent relative movement between the journal box and side frame.

5. A pedestal truck side frame having four lugs for embracing adjacently arranged bolt lugs of the journal box, and having two Hanges connecting certain of said four lugs for embracing shoulders on Athe journal box normally to prevent relative lateral movement between said side frame and journal box.

Signed at St. Louis, Missouri, this 20th day of March, 1920.
