vPPLIMTION FILED DBC 17, 1906. Patented May 30, 1911.
5 ZMSWT y?? ELLA wf L@ appliation ined December 1 7, 1906. f serial No. vestati.; 't'
To all whom# ma/y concern:
' Be it known that I, HARRY S. HART, a citizen of the United States, residingk at Chicago, in thecounty ofCoOkand State of Illinois, have invented certain new and useful Improvements in Car-Trucks, of which the following is a specification.
' The object of my invention is. to provide a carv truck in which the bolster maybe at- I frame, or, if -a nonintegral side-frame`is .tached to the side frame of a truck by means that willy permit the use of an integral. side used, will permit the removal of the bolster f from the side'frame Without Separating the parts of the side frame. I
My 'mproved construction embodies means whereby the bolsterI maybe separated from the side frame without disarranging any of the other parts of the truck.
' Infthe drawings-Figure 1 is a side view of a truck constructed in accordance with my invention,l the bolster being removed. Fig. 2 is a plan view, partly in section,
v showin the bolster in place. Fig. 3 is-an enlarge transverse section showing the up- 4per arch bar and part of one of the ylocking members. f
In order to remove the bolster without disarranging other parts of the truck, I make parts of the inner walls of the columns d movable vertically or substantially vertically thereon. These removable partsare designated by theletter f, and, as ap the members f and in the columns d. These,
bolt-holes are countersunk upon the inner faces of the members f, in order that the.
bolts, when in position, may be Hush with the faces of those members. Said bolt-holes extend in the plane of the opening throughA the columns d. The bolt-holes are spaced apart vertically a' greater distance `than the thickness ofthe bolster. This will permit the upper bolts to be removed when .thebolster4 is pressed downwardly slightly. The
lower bolts maybe removedwhen the bolster is elevated slightly. In both cases the bolster may be pressed away vfrom itsnor-`v` mal position sufciently to permit the bolts to be freely removed. l In a similar man-` ner the bolts may be restored to their posi\ tions.
A It-will be understood that-the 'bolster is` 'supported by springs and that it reciprocates vertically when the car is in use.' The bolster therefore is constantly sliding over the eounter'sunk heads of both lthe upper and lower bolts and .they have no chance to become displaced. l
I have illustrated a vbolster ofa common form providedwith projectionsm.` Instead of directly'engaging the columns, asin the` usual form of construction, the projections Hannypfsnnnr, or c nicrieo, ILLINOIS; Assien'o'ri' To woirr'lrt cir itfngxlii com;
" PANY, OF omesso, ILLINOisjA CORPORATION or Marian m in my improved truck engage the removable locking members The parts 'are so proportioned that, the bolts being removed, the members fmay slide vertically upon the inner faces of the columns d, downward `to a point wherethey 'will be. out off'engagement with the projections m upon the bolster. Y
-In assembling the parts, the locking mem. bers f are either removed .altogether or slid downwardly upon the columns to their lowermost position. The end of the bolster is then inserted'between the columns (Z of the side 4frame and when .properly positioned themembers f are moved upwardly into the space between the sides of the bolster and the integral portions ofthe columns d, The
movable locking members f are then secured in place, thus also securing the bolster against longitudinal displacement,7but
permitting it 'fthe necessary `vertical vmovement upon the springs. i
It will be understood that instead of providing two movable interlocking members f I may provide one of double thickness illustrated in the drawings. l.Vl/'hen using a single locking member of double thickness, the projections m upon one 'side of the bolster` will enga e such locking member and upon the opposite side will engage the column d in the usual mannen The removal of the single locking member inthe manner aboveI described vwill permit the bolster e to "be moved sidewise suiiiciently to disengage the projections lm, from the Opposite column,"-
,thus providing for` they.A separation of thefuo bolster and side frame.-
esame It will be understood that the bolts kv are spaced apart vertically to a sucent veXtent to permit-of their removal Without interference from the bolster.
What I claim is:
In combination, a side frame ,provided with a bolster opening, a b'o1ster`,' projecting guides on said bolsterfand flanged interlocking members engaging the sides of said 10 opening, said interlocking members and the sides of said opening being provided with bolt holesextending 'in the plane of said opening, said bolt holes 'being spaced apart vertically a distance greater lthan the thick'- ness of said bolster.
