OOOOOO UNITED STATES PATEN HERMAN FRIES, or MICHIGAN CITY, INDIANA.
- UNDERFRAMING FOR CARS.
To all whom it may concern:
Be it known tl1at I,' HERMAN PRIES, a-citizen of the United States, andresident of Michigan City, county of ,Laporte, and State of Indiana, have invented certain new and useful Improvements in Underframing for Cars, of which the following is a specification,
- and which are illustrated in the accompany.-
ing drawings, forming a part thereof.
This invention relates to un'derfraining for freight cars of various types, and is appli cable to structures in which either metal or wood sills are used.
generally improveon the detail plan view is a cross-section of; the bottom of a The object. of the invention is to secure both great strength and simplicity, and to art as now practiced." L QThe invention consists 1n the structure .her'einafter' described, and which is illustrated in the which I Figure 1 is a detail side View of the underframing of a car, some portions being omitted and others being broken away, and some parts being shown in cross section; Fig. 21's a accompanying drawings, in
some portions beingbroken away and parts of the structure being omitted; Fig. 3 is a cross-section of the bottom of a car showing one of the body bolsters in elevation; Fig. 4 car show- 1ng one of the cross-ties in elevation; Figs. 5 and 6 are detailcross-sections of a car bottom showing'a portion of the body bolster in elevation and illustrating modified forms of construction; Fig. 7 is a detail longitudinal section of the bottom of a car showing the body bolster in cross-section.
The floor of a car is represented at 10 and its end sills at 11 and-12, the usual truss-rods 13 extending longitudinally of the car and uniting the end sills-.-
' In the preferred form of cohstruction the longitudinal sills are of metal and have the form of-channel beams; the center sills being shown at 14, 15, the side sills at 16, 17, and
tom of the floor 10,'while the upper faces of the side and intermediate sills are preferably in contact therewith. -N ailing strips 20, 21, are interposed between the center sills and the car floor, and, nailing strips 22, 23 and 24, 2511 s adjacent, res actively, te the side Specification of Letterslatent.

and center sills'and rest upon brackets 26, 27- and 28, 29 secured thereto. I
- The body bolsters are sectional in form, and the center sills are incorporated into them. Each of these body holsters oomprises two end sections, each formed of a pair of flanged plates 30, '31, preferably, though .not necessarily, of cast metal. These plates form the vertical sides of the end section of the bolster. At their wardlyturned flanges 32, 33, which lie against and are riveted to the outer face of the center sill, as14 (see Fig. 7).
The vertical width of the plates 30, 31, is the same as that of the center sills. Their upper faces are offset down- 'wardly to accommodate the intermediate and side sills, as plainly shown in Fig. 3, the offset forming shoulders 34, 35, against which the inner faces of the intermediate sills 18, 19, take bearings] The plates 30, 31, have outwardly directed top flanges 36, 37, throughout their lengths, to which flanges the side and intermediate sills are riveted, as shown at 38, 39. A. tension member 40, .considering the body bolster as a truss, in the form of a plate rests upon and is riveted to the to flanges 3.6, 37, extending between the shouldbrs 34, 35. I v
The bottoms of the two bolster sections30, 31, incline upwardly ends, and are provided with inturned flanges 41, 42, to'which is applied and riveted the compression truss member'43, in the form of a plate, the length of this plate being optional with the builder, preferably being somewhat less than the extreme length of the bolster, as shown in Fig. 3.
By reason of the described arrangement of top and bottom bolster flanges, the tension member 40 is of greater width than the comression member 43, thus providing, the
/r naximun i sfrength where most requisite, the
, compressio pair of .iilli g lates 44, on one of which is shown in he rawings, located between the center sill inline with the side plates 30, 31,
and havi outstanding vertical flanges 45,
46, secured to the sills by the same rivets 47 which secure the end flanges of the plates 30,
I 31, thereto.
The usual center plate 47 is secured to the bottom of the'bolsterfor engaging the center plate 48 of the truck bolster.
In hat or gondola car construction the outer end of the bolster takes the form shown in Fig. 5, being ofl'set (.lownwardly, as shown 1 at 55, to form a seat for the side sill 56 to bring the outer face thereof llush with the side edge of the floor 10, a nailing strip 57 being in this case mounted upon the top of the side sill and a stake bracket 58 being attached to the outer face of the sill.
The cross-ties 59, 60, located between the two body bolsters, are in the form of straight I-beams, and areriveted to the lower faces of the center sills, as shownat 61, 62, Fig. l, and are of less length than the width of the car bottom. Chairs 63, 64, rest upon and are riveted to the cross-ties adjacent their ends, and support and are riveted. to the side and intermediate sills, these chairs being in the form of flanged plates and being prolonged outwardly beyond the ends of the cross-ties for engagement with the side sills. This construction of the cross-ties and their accessories, while insuring ample strength, provides side clearance for the car frame, thus lessening the danger of injury to the structure by extraneous objects. The usual struts 65, 66, for the truss-rods 13 depend from and are secured to the crossties.
In the construction illustrated in Fig. '6,
I the side sills 67 and intermediate sills 68 are of Wood and directly support'the car floor 1'0, supplemental nailing strips not being required.
I claim as my invention- 1. In an underframing for cars, in combination, a pair of center sills, a cross-tie of less length than the car frame and secured to the under faces of the center sills, ed upon each end of the cross-tie and projecting up ardly and outwardly, and side and intermediate sills resting upon such chairs.
a chair mount- 2 In an undertramingfor cars, in combij nation, a pair oi center sills, bolster sections projecting laterally troin the outer faces of l the center sills and each comprising a pair of plates having their-upper edges flanged outward and their lower edges flanged inward, l tension and compression plates uniting the l bolster sections and being secured, respecl tively, to their outturned and to their in- 1 turned flanges. l 3. .In an underframing for cars, in combil nation, a pair of center sills, bolster sections projecting the center sills and each comprising a pair of vertically-disposed plates having the outer portions of their upper edges oliset downwardly and the inner portions thereof outwardly flanged and having their lower edges inwardly flanged, tension and compression plates uniting the bolster sections and being to their outturned and and outer sills resting of the bolster secsecured, respectively, their inturned flanges, upon the offset portions t-ions.
4. In an underframing for cars, in combi nation, a pair of center sills, bolster sections projecting laterally from the outer faces of the center sills and each comprising a pair of vertically-dis osed plates having the outer portions of t eir upper edges ofl'set downwardly and the inner portions thereof outwardly flanged and having their lower edges inwardly flanged, tension and compression plates uniting the bolster sections and bein secured respectively to their outturned an their inturned flanges, upon the ofiset portions of the bolster sections and extending above the center sills.
