Application filed April 5.1907. Serial No. 366.459-
To all whom it may concern:
Be it known that I, JOHN MoE. Arms, 2.
- citizen of the United States, and a resident of Dongan Hills, in the county of Richmond, and State of New York, have invented'certain new and useful Improvements in Double Body-Bolsters for Railway-Cars, oftwhich the following is a specification.
' ing adapted for passenger cars and enabling from the use of structural beams for the center or draft sills and side sills in lieu of wooden center and side sills commonly used in the construction of passenger cars.
The invention will be fully understood the detailed description hereinafter presented, reference being had to the accom panying drawings, in which:
Figure 1 is a to view of a cast double body bolster embo ying my invention, the center and side sills being omitted; Fig. 2 is a side elevation, partly broken away, of same,
the bolster being in one longitudinal half of and the center and central vertical section side sills being shown in position and in section on the bolster; Fig. 3 is a vertical transverse section through the bolster on the dotted line 3-3 of F'g. 2; Fig. dis a top view of about one-half of one side of the bolster and illustrates a modification in the method of securing the side and center sills to the bolster; and Fig. 5 is a side elevation of same, the side and center sills being in section.
In the drawings, des1gnates the side frames of the double body-bolster, 11 a central beam-extending in line with the length of the car and connecting said side frames, 12 end beams. connectin said side frames at their end portions am? 13 beams connectin said side frames at points between the centre beam 11 and end beams'12, the whole being in one, integral casting and said side frames being approximately 1n their body portion of I-shzipe in cross-section and formed integrally upon their up er surfaces with the vertical flanges 14 w iich' are integral with theside frames and extend between their central and end portions and not only ma- "ward their outer ends.
ing these whose ends are integral with the side terially strengthen the structure and. increase its efficiency but afford means for" the proper securing of the ter or draft sills to the bolster. p
The side frames 10 are deeper at theiiicenl tral than at their end horizontal flanges'of said side frames are on about the same horizontal plane with the general upper surface of the central connectf mg beam 11, whlle the'flanges 14rise above the general horizontal upper surfaces of the beams 10 and are separated at their inner ends at each side of the bolster so as to re ceive between said ends the centeror draft sills 15 (Fig. 2), the latter being rigidly connected with said flanges 14 and mounted .upon said side frames.
In the construction shown in Figs. 1, 2 and UNITED STATES ATEN OFFICE side sills and cenportions aiid the-upper 3 the ends of the flanges 14 are cast with elevated [knee portions having laterally 18, 19, respectively, and forming below them 16, 17, respectively,
'75 extendingvertical flanges and above the upper flanges of the side frames recesses 20, 21, res ectively. The center sills 15 are shown in ig. 2 as riveted to the flanges 18 of the knees 16 and, as illustrated, the recesses 20 receive flanges of said center sills and enable the web ofthe sills to bebrought flush a ainst said flanges 18. The side sills 22 are flanged and rivetedto the flanges 19 of the end knee portions 17, and the lower flanges of the side sills pass within the recesses 21 formed below said knee portions and rest upon the upper surface of the side frames. 7
The central connecting beam 11 has cast upon its u per surface the. vertical web flanges 23 W nch extend from one end to the the lower adjacent other of said beam and preferably cross the side frames 10, said flanges 23 being highest at their middle portions and thence ta ering or inclining outwardly and downwar ly to- The flanges 23 'add greatly to. the strength of.the connecting beam 11 and to the bolster as a whole and they are stiffened by web flanges 24 connecting their sides with the upper surface of said beam 11. prises a main horizontal upper flange .25, a lower flan e 26 and a vertical'web 27 connectanges, the whole forminga proxi- *shape frames 10, as represented'in Fig. 3. -Intermediate the flanges 25, 26 of the beam 11 is formed a mately in cross-section a beam of The connecting beam 11 com-r 55 seats for car center-sills and integral vertical cylindrical section 28 for the usual centerin, and centrally below the flange 26 is orrned the body center-bearing 29.
The beams 12 connecting the end portions of the side frames 10 are trian ular in crosssection, as shown in Fig. 2, and the connecting beams 13' are preferably of I-shape in cross-section, as also shown in Fig. 2. At their central portions I preferably widen the lower flanges of the beams 13, as at 30, and form vertical webs '31 connecting the members of said beams, thereby strengthening said beams 13 at their central portions.
The entire double body-bolster shown in Figs. 1, 2- and 3 is formed in one integral casting and the flanges 14 have knee portions on their ends adapted to at once directly receive the center and side sills, and the said bolster has been designed with a view of securing an efficient distribution of themetal throughout the same and of producing a structure capable of ready manufacture and. of great strength and durability.
In Figs. 4 and 5 I illustrate a modification of a portion of the invention, this modifica tion being presented more particularly to indicate that I may omit the formation of the knee portions 16, 17 directly on the ends of the flanges 14 and connect the center and side sills of the car with the ends of said flanges by means of angle' iron plates or knees 32, 33 riveted to the sills and to said flanges 14, as will be clearly understood from an inspection of Figs. 4 and 5 without further detailed explanation. I also in Figs. 4 and 5 illustrate the side-frames as formed with sunken seats 34 to receive the lower flanges of the center sills 15, this being desirable. in instances in which the distance permitted below the center sills is insufficient to enable said sills to be mounted directly flanges I4; across the central upon the main upper horizontal portions of the side frames 10. In the construction shown in Figse and 5 I may also carry the ortions of the side frames 10, as at 35, inor er to make use of additional angle iron knees 36 riveted thereto and to the center sills 15 for more .56 securely fastening the said sills.
