CAR-TRUCK- SPEGIFIGATION forming part of Letters Patent No. 773,564, dated November 1, 1904.

Application filed April 15, 1904.

To all whom it may concern.-

Be it known that 1, JOHN GREEN, a citizen of the United States, and a resident of the city of St. Louis and State of Missouri, have invented a new and useful Improvement in Car- Trucks, of which the following is a specification.

My invention relates to car-trucks, and especially to side frames therefor, and has for its principal objects to provide a east side frame which may be assembled with the bolster without making any part of the truck removable, to provide a side frame so arranged that the truck-bolster can be inserted endwise into the side frame, to provide a side frame with removable bolster-guides, to provide a side frame having removable bolster-guides to be applied after the truck-bolster has been put in place, to provide a side frame having integral journal-box-retaining lugs, to provide a side frame so connected to the journal-boxes that the latter can be removed without raising the side frame a distance equal to the height of the journal-box, to provide a side frame having pivoted journal-boX-retaining means, to provide a side frame with removable journal-box-retaining means which will not fall out of its own weight, and other objects hereinafter more fully appearing.

My invention consists in the parts and in the arrangements and combinations of parts hereinafter described and claimed.

In the accompanying drawings, forming a part of this specification, and wherein like symbols refer to like parts wherever they occur, Figure l is a side view of my improved truck. Fig. 2 is a view of the central portion of the side frame, showing the manner in which the removable bolster-guides are inserted. Fig. 3 is a fragmentary view on the line 3 3 of Fig. 2. Fig. 4: is a view showing the end of the side frame arranged for insertion or removal of the journal-box. Fig. 5 is a fragmentary view on the line 5 5 of Fig. 1, the journal-box-retaining bar being removed; and Fig. 6 is a plan view of a journal-boX-retaining bar.

The side frame 1 is provided with a peripheral flange 2, the web 3 being comparatively thin. There are projecting shoulders 4 5 at Serial No. 203,241. (No model.)

the upper corners. Near the outer extremity of each shoulder is a bolt-hole through which bolts 6 7, respectively, may pass. In hithertoknown forms of side frames it has been customary to provide bolt-holes near the point at which the shoulders join the body portion of the frame. This is objectionable, as it weakens the frame at the point at which it is subjected to considerable strain. It also involves expense to drill or ream out the holes. On the present side frame lugs 8 9 are provided upon the lower side of the shoulders 4: 5, respectively, in position to engage the holes in ears on the journal-box ordinarily provided to receive securingbolts. Upon each of the lower corners of the side frame are oppositely-extending pairs of round lugs 10 11, integral with the side frame. Journal-boX-retaining bars 12 13 are secured by means of the said lugs 10 11. The end of each bar toward the side frame is bifurcated and curved to fit under the lugs 10 and over the lugs 11. The curved bifurcated portion is so long that the bar must swing past the position in which it would be held by gravity before it can be disengaged from the lugs 10 11. Thus the bar is securely held against dropping'off while being easily removable at will. By this construction the objectionable use of bolts and nuts is avoided. The bars are secured by parts integral with or permanently a part of the body portion of the truckframe or the bars. By parts permanently a part of the structure are meant parts the removal of which is unnecessary to permit the removal of the bars. Lugs 1 15 are provided on the bars 12 13, respectively, near their pivot-points, so that they will be immediately beneath the lugs 8 9, respectively, when the bars are in a horizontal position. These lugs are in position to engage the holes in ears on the lower corners of the journalboXes. At their outer ends the bars are provided with bolt-holes. The bolts 6 7 pass through the bolt-holes in the shoulders 4 5 and retaining-bars 12 13, respectively, and through holes in ears upon the journal-boxes. Nuts 16 17 on the bolts 6 7, respectively, hold the retaining-bars 12 13, respectively, in a substantiallyhorizontal position. The journal-boxes are thus securely retained in position. When it is desired to remove the journal-boxes, it is only necessary to remove the bolts and jack up the side frames a height equal to the length of the lugs 8 9. The wheels can then be rolled away from the truck, the journal-boxes moving out horizontally.

Near the middle the side frame has a substantially rectangular opening 18, which is bounded by a flange 19. The sides of said opening are integral in the bolster illustrated; but permanently-connected sides, as in a builtup truck-frame, would be equally within the scope of my invention. The lower middle portion of the opening is wider than the upper portion thereof for a purpose hereinafter appearing. The upper portion of the opening 18 is wide enough to permit the insertion endwise of the bolster 20 to be used therewith. In other words, its width is equal to the width of the bolster measured over the column-guides thereon. A cross-tie 21, having seats for springs 22, is secured to the flange on the lower side of the opening 18., The

bolster 20 is guided in the frame by means of a bolster-guide member 23, comprising bolster-guides 24C 25 and a connecting-plate 26, integral therewith. The bolster-guides are substantially U-shaped in horizontal section and are arranged to embrace the flanges forming the vertical sides of the upper narrow portion of the opening 18. Their outside dimensions are such that they fit between the column-guides 27 28 on the bolster. The springs 22 are seated between the lower side of the opening 18 and the plate 26 of the bolsterguide member 23. Thus the bolster-guide member will vibrate with the bolster and will be guided by the vertical walls of the narrower portion of the opening 18. The outside dimensions of the bolster-guide member 23 are such that it may be inserted in the wider portion of the opening 18. In assembling the truck the bolster is inserted. Then the bolster-guidc member 23 is inserted in the wider portion of the opening 18 and slipped up between the column-guides on the bolster. hen the springs are placed in position.

Obviously the device admits of modification within the scope of my invention, and therefore 1 do not wish to be limited to the specific construction shown and described as an illustration of my invention. For example. although a cast frame is shown in the drawings the invention is equally applicable to a built'up frame.

What I claim as my invention, and desire to secure by Letters Patent, is
