THOMAS NATHAN RUSSELL, OF CHICAGO, ILLINOIS, ASSIGN OR TO CHICAGO-CLEVELAND- CAR ROOFING COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

Original application filed August 6, 1915, Serial No. 43,924. Divided 1915, Serial No. 68,312. Renewed June 27, 1918.

-- connecting the ridge pole and purlins to the carlines, and particularly the end carlines;

to provide improved means for connecting together wooden and metallic frame members; to provide improved means for supporting the end of the roof; and generally, to improve, cheapen and simplifythe con-- struction of car frames,.and particularly the roof frame ofcars. h

In attaining these and other objects and advantages to be hereinafter pointed out, I have provided a'construction one embodiment of which is illustrated in the accompanying drawings, in which Figure 1 is a longitudinal, vertical, central section through the upper part of the end of a car constructed in accordance with my present invention; v

Fig. 2 is a perspective view of the bracket or shoe provided for connecting the r dge pole and purlins to the end carlmes; and

Fig. 3 is a erspective view of a mod fied form ofbrac (et for use with the carhnes intermediate the end carlines.

In the form of construction shown in the drawings the end carline 13 is of Z-shaped section, the lower flange 40 of whlch 1s connected to the -Z-shaped end posts 12 by means of angle pieces 14. The upper flange 39 of the carline 13 is connected to the wooden ridge pole 15 by means of the bolt 17 Movement of the rid e pole relatively to the carline is prevente not only by the bolt 17 which passes through the upper flange of thecarline, the rldge pole and the central roofing strip 30, but also by means of a shoe or bracket 18.'

The section shown in Fig. 1 is taken through the ridge pole of the car so that Specification of Letters Patent.

- prevent lateral movement thereof.

CAR CONSTRUCTION.

Patented Feb. 4, 1919. and this application filed December 23,

Serial No. 242,311.

the central roofing strip 30, to which the wooden roof is attached, is shown, as are also the transverse members 32 and 48 which carry the running board 33. The outer end of the running board is supported from the end plate 2.3 by means of a bracket 33. It will be observed that the outer end of the roof through the roofing strip and ridge pole is firmly supported by the outer part of the bracketor shoe 18. By this construction the strain on the end plate is relieved and 7 this is important as there is more strain on this portion of the roof than any other owing to the fact that it is the part on which the brakeman steps when passing from the ladder to the running board or to operate the brake wheel.

The shoe or bracket 18 is formed with two vertical side portions 19 adapted to engage the two sides of the ridge pole or purlin and These side portions are provided with laterally projecting horizontal wings 20 riveted or otherwise secured to the upper flange 39 of the carline. These laterally projecting wings make it unnecessary to provide a webon the shoe which would lie between the flange 39 of the carline and the lower surface of the ridge-pole or purlin. Consequently, the ridge pole or purlins rest on the upper surface of the carline, as distinguished froma surface depressed below the surface of the other portions of the carline. The two side portions 19 21re connected at the end by the vertical portion 21 adapted to engage the end of the ridge pole or purlin and prevent longitudinal tively to the carline. Vertical flanges or webs 12 are provided to support the projectingportion of the shoe or bracket 18. The

projecting parts of the side portions 19 are connected by a horizontal portion i3 whose upper surface is flush with the upper surface of the-flange 39 of the carline. By means of this construction a horizontal bearing or supporting surface for the ridge pole or purlin is obtained whose length is considerably greater than the width of the upper flange of the carline. This is particu- 'larly important where the upper flange 39 of the carline decreases in width progressively from the sides of the-car toward the center so that adjacent the running board the flange particularly narrow in width. In

movement of these parts relaaddition large lateral bearing surfaces are the bolt 17 from such function, whichis important as the bolt has a comparatively small bearing surface on the wood of the ridge pole or purlin. Not only are the bearing surfaces increased, but also the construction of the upper end of the car is strengthened by the fact that the end plate 23 can a be clamped directly by the bolt 49 against the vertical end portion 21 of the shoe 18 and is thereby more securely held in position than would be the case if it were secured to the end of the ridge pole o purlin.

Fig. 3 shows a modified form of shoe 44.- for use in connecting the carlines intermediate the end'carlines to the ridge pole or purlins. Its construction is similar-to that of the shoe 18 except that there is no end portion equivalent to the part 21. The other parts,

namely, the vertical portions 19 the laterally extending wing 20*, the depending flange 22 the vertical flanges 42 and the horizontal portion 43 act in analogous manner to the parts 19,20, 22, 42 and L3 of the shoe 18.

Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent is:-

1; A car construction comprising, in con bination, a longitudinal roof member, an end plate, a Z-shaped end carline having an inwardly directed upper flange an outwardly projecting lower flange and a substantially vertical central. web, a shoe for connecting said longitudinal roof member to said carline attached to said upper flange and projecting over the lower flange of the ca'rline with its outer end in contact with said end plate. D

A car construction comprising, in combination, a longitudinal member, a carline having a substantially fiat upper surface, and a surface from, a bracket attached .to sa1d last-.men-

downwardly directed theretioned surface having an upper surface sub stantially flush with the upper surface of said carline, portions on said bracket adapt- .ed to engage the sides of the longitudinal member and the upper surface of the carline, means for attaching said portions to the carline, and means for attaching said longitudinal. member to said carline and said bracket.

3. A car construction comprising in comand in contact with the low r bination. a longitudinal wooden roof member, a Zl-shaped carliuc hating its central web vertically arranged, a bracl tet engaging said central web on the side opposite the upper liangc and extending m'er the lower flange of the carline, the upper surface of the said bracket being snlritantialiy flush with the upper surface of said upper flange face of said roof member, and an upwai projecting portion on said bracket adapted to engage the end of said roof member. it

4. A car construction comprising, in combination, two roof members substantially at right anglesto each other siuperimposed on each other, and a shoe mounted on the lower member comprising a portion projecting laterally from the side of said lower member having. an upper surface substantially iiush with the upper surface of said last-mentioned member, and portions ada ted to engage the sides of the upper incinher and the upper surface of the lower member, and means for attaching said portions to said lower member.

5. A. car construction comprising. in combination, an end carline, a wooden purlin resting on the upper surface of said car line, a shoe on said carline adapted to contact with a vertical face of said carliue and with the 'undersurface of said purlin. adjzc cent said vertical face of said carline, and also with the sides and end of the purlin.

6. In a car roof construction. in. combination with a carline and a wooden. purlin; a,

' member adapted to maintain said. and purlin in predetermined position a flat surface adapted to abut laterally a at the ca e, a socket. having side and em. ,-.ort1ons irate from said firstmentmno... member nd adapted to restrain the purlin from 1 ral and longitudinal movement relative to the carline. and means for securing the abutting surface of said socket member and said airline to gether whereby they may be restrained from relative distortion.

In testimony whereof l: have hereunto signed my name in the presence of the two subscribing witnesses.
