To all whom 'it may concern:

Be it known that I, GEORGE G. FLOYD, 'a citizen of the United States, residing at Granite City, in the county of'Madison and State of Illmois, have invented certain new and useful Improvements in Car-Truck Side Frames and J ournal-Boxes, following is a specification. n

This invention relates to railway 'car trucks and moreparticularly to trucks which. are constructed so that the journal boxes may be readily removed from the side frames. 7 n a One of the objects ofthe presentinven- 'the'side frames and the journal boxes which permits the boxes to automatically adjust transversely 0 the side frames so that a uniform bearing is secured throughout the full length of the journal portion of the axle, th1s connection-being so constructed and arranged that it will not interfere with the normal adjusting movements of the box- 5 relatively to the frame but will act .in cases of emergency to prevent the boxes from separating from the frame. Furthermore the connections between the boxes and frames are so constructed that there is no wear upon these parts diiring" the ordinary adjusting movements of the box, and also so that there'is no tendency for the connections to work loose under. any conditions of service.

consideration of the following description when taken in connection with the-accom panying drawings illustrating one preferred embodiment thereof.

In the drawings-Figure 1 is a fragmentary elevation of portion of a car truck showing one end of le'hide frame in elevation and the journal boxin section, this view being taken substantially on the line 1-1 of Fig. 2; and Fig. 2 is a side elevation showin the side frame in section, this view being ta en substantially on the -,line 22 of Fig. 1. Q eferring to the drawin 5 designates the side frame of a truck w ich may be of any preferred or desiredlgeneral shape, having at each end depending-portions 6 and 7 forming rigid jaws spaced apart to receive box 8 between them. The'sides of which thetion is the provision of a connection between" themselves longitudinally of the'axles, i. e.,-

receive th .c onvex bearing Other objects and advantages of the present invention will be made-a parent from av is provided wit of the "ournal box are provided with spaced ribs 9 tween which the jaws 6 and 7 are adapted to enter. It will be ap arent from Fig. 2 that the jaws fit loosely etween .the ribs 9 so as to permit limited movement of the box relative y to the side frame, while at the same time eifectually preventing undue movement of the box transversely of the frame; It will also be noted that the jaws 6 and 7 disposed upon either side of the box prevent displacement of the box longitudi nally'of the frame. I

In the present modification the side frame rests loosely upon the journal boxes and that portion of theframe intermediate the jaws 6 and 7 is rounded or convexed at 10 and isadapted to loosely rest up? a seat or saddle 11 so as to permit roe g movement between the journal box and the frame. It will be a parent from Fig. 2 that the sad- 75 dle 11 is ormed integral with the top of the journal box and its upper face is concave to surface of the side frame. The rocking movement of the journal box transversely of the frame is permitted by reason of the fact that the curva- 'ture of t e bearing face of the side frameis eater than the curvature of the supporting ace. of the saddle. This rocking movement of the journal box transversely of the side frame is' rovided for the purpose of securing a uni oi-m bearing throughout the lengthof the bearing brasses (not shown) on the journals of the axles 12.

While a limited rocking movement between the journal boxes and the side frame is desirable, as above indicated, it is also ver desirable that the journal boxes, axles' an wheels. shall be secured to the side frame so that th'ey -wi1l be carried therewith in, case a car truck becomes derailed or upset, rather than to permit a separation of the parts of the truck. For the urpose of securingthe frame and journal boxes together I-have provided each journal box with upstanding ears 3 spaced apart and disposed adjacent the outer side of the saddle 11. The side frame above the bearing' face 10 is provided with a laterally projecting lug 14 adapted to roject between the 105 cars 13 when the journa box and side frame are in normal '0 erative'position.' This lug an elongated aperture or slot 15, the longer axis of which is disposed in a planecoincident. with the longitudinal axis of the ears 13 which arealso provided with apertures or perforations-l6 disposed in alinement with thelongitudinal axisof the shank portion of such bolt being of a'" less diameter than that of the apertures 15- and l6.- In 'order tomaintain this bolt cen trally dis os'ed'with relation to such 'ap er-: tures so t at it may be out ofcontact' with through.

tension of a lockingnpt 22.

It will be evident thatwhen the partsthe slot'15. A bolt 17 'isfpassed through the apertures of both ears,.13 and also through the slots 15 ofthelaterally projecting lug 14,

the walls of the slot 15, and so'that it will be unnecessary todrill or finish the holes 16,

I provide the bolt at one-end with a head 18 portion 21 adapted to fit in the aperture 16 of the other car, the outer face of the nut being adapted to receive the are assembled and the bolt is in place with the nuts thereon screwed up tightly, the co'nicalparts 19 and 21 act! to maintainth'e bolt centrally withrelatio'n to the. apertures 16 and the slot 15, and wholly out of contact with the wallsiof the slot. It will, also be apparent that the bolt will not interfere .with the normal rocking movements of the journal box transversely of the .frame but will act in cases of emer ency'to preventv .the'box and frame from apart or separated.

' When the parts are assembled as shown on the drawings all the weight-of the car body is transmitted to the journal boxes through the 'side frame which rests loosely I in the saddles 11 formed on the top of the journal boxes. Under servie the journal boxes can rock transversely. of the side frame by reason of the loose engagement between the bearing surfacelO of the side frame and the journal box saddles, the rock-. ing movement permitting the journal boxes to adjust'themselves longitudinally of the axles so as to secure a uniform wearing on the journal brasses. During these normal rocking and adjusting movements the bolt 17 is not in contact with the walls of the slot 15 with which the laterally projecting lug let is provided and consequently the adjusting movements of the boxes are not hampered or interfered with by Che enier gency bolt nor is the boltsubjected to wear or strain during the normal running of the car. If, however, the truck should become derailed or upset in sucha manner as to tend to separate the side frame from the journal boxes, the emergency bolt by reason of its'engagement with the lug 14will prevent the ournal boxes and axles from withnical exsoribed'.'

oming drawn draw ing separation of the parts.

While I have shown and described in detail hone p eferred embodiment of my invention it: will be apparent that it is susceptible of considerable change in the size, =shape,'proportion and arrangement of the varlous parts without departing from the spirit ofthe invention or sacrificing any of the material advantages there'f.

I claim:.
