UNITED sTATEs PATENT o FFE? @FRANCIS L.' COLE, or' rNDrANAPoLI's, INDIANA.gl ,i 1

To all whom it may concern! .BeitknownthatL FRANCIS L; COLE, a citizen of the'United States, and a resident'o'f Indianapolis, county of Mariomand State of Indiana, halve invented a certain useful VDraw-Bar Construction; and I do hereby declare thatthe following is a full,

yclear, and exactfdescription thereof, Areference being had tothe 'a'ccompanying draw-` ings. 1 v l The object of. this invention is to provide an improved draw bar construction for railway cars, wherein the draw bar .will be readily removable and atthe same time cannot vbe pulled out of place and there will be tical section through the rear end of a locomotive tender, parts being broken away. Fig. 2 is a plan viewof the draw bar frame by itself.- Fig.` 3 is a transverseV section 4onthe line 3 3 of Fig. 2. Fig. 4 is a horizontal section on the line 4 4 of Fig. 1,

k.looking upward. Fig. 5. is a vertical transverse section on the line 5 5 of Fig. 1. Fig. '6 is a vertical 'section on the line 6 6 of Fig. 1. Fig. 7 is a horizontal section on the line 7 7 of- Fig. 5. A

While the invention -is here shown in connection with a' locomotive tender, it is not limited to such use, but is the same for any car.

In the drawings herein shown which --are `for the purpose ofillustrating the general nature 'of the invention, 10 represents a part of the locomotive tender and 11 the flooring.

12 are longitudinal beams in the central portion of the tender andthere is a cross beam 13 at the end the car. The latter beam is faced by the plate14.

15 is a draw bar with a coupling 16 at one end and the inner end is laterally widened to provide equal shoulders 17, he inner end of the ldraw bar is secured within `a loop frame 18, as shown in Fig. l, by rivets 19, the forward end of said -frame'lS having in-turned ends which overlap the shoulders 17 of the draw bar. The sides of this looped frame 18 are open and within said DRAW-BAR .eoNs'rRUorion Patenteineegaiiiiral Appiiaaonaiea March 23, 191i.

contracted ends of the opening 26'is slightly greater than the width'of the loop franielS, as shown in Fig. 4, where thev rear vertical end of said loop frame? appears.l The .fol-v lowers 21 and 22 also abut against inwardly extending ribs 30 iromthe side walls'` 31 of said draw bar frame, 'as appears in Fig. 4, whereby said'ribs 30y serve as stops to limit the movements of the followers. The draw bar frame is rigidly secured to the, beams 12 and 13 by bolts 33 through the top plate 25l of said frame, see Figs. 1, 4 and 5.The sides 31 and top plate. 25 ofsaid draw bar frame are reinforced by the triangularribs 34 on the outside of thewalls 31 and which are shown in Figs. 4L and 5. In order vto 4more securely'mount the draw .bar fraine the flange 27 projectsl up into a recess at 35 in the rear wall of the cross beam 13, as shown in F ig. 4.- Likewise through the inner end there is 'a pair of flanges 36 extending upwardly from the top plate 25 of the draw bar. casting in to corresponding recesses 37 inV the longitudinal beams 12, as shown in Fig. l.

The drawlbar frame which has juist been 'described is cast integral, and to the same there is added a longitudinally extending bottom plate 40 under each side portion of the draw bar trame and said plates are secured to the draw bar frame by bolts 41, as appears in Figs. 4, 5 and 7. These bolts pass-through horizontally flanged plates 42 integral with the draw bar frame and adjathe cent the vertical ribs 34 thereof and through the ends of the plates 40 and the extreme ends of said plates 40 are turned upward, as shown in Fig. 1. A strap 43 extends under said plates 40 near the middle and under the lower part of the loop frame 18 and said strap 43 is secured by said bolts 41 through the flange 42 and its ends are upturned, as shown in Fig. 5. j The strap 43 has its ends 47 bent to extend past the projection 46 from late 40 and the lateral extension 42.

T e central portion of the draw bar is supported by a cross plate 5() which at'each ythe invention is not necessarily 'inwardly by the draw bar.

end is secured by bolts 51 to laterally eX- tending flanges 52 from the lower edges of the forward portion of the draw bar frame, as appears more fully in Fig. 6.

While I have shown and described details in the construction of the draw bar frame, limited to some of said details.

In operation when the draw bar is bumped the follower 22 will be forced inwardly against the spring and the thrust will be resisted by the pair of ribs 3() and inner pair of shoulders 29, the follower 22 being pushed movement of the draw 'bar is stopped-by the plate 14 on the beam 13 and does not strike the draw bar frame and for that purpose the front edge of the upper part of the draw bar frame atis cut away somewhat. The pull on the draw barcauses the contraction of the spring, the looped frame 18 moving the rear follower 21 andthe barrel from the position shown in Fig. 4. Such pulling strain comes on the outer pair of ribs 30 and the shoulders 29 of the draw bar frame as the spring presses against the follower-22 and it against said ribs and shoulders. Dislocation of the draw bar frame by reason of the pull or strain on the draw bar is resisted by the [lange 27 behind the beam 12 as well as the bolts The end of the flange 27 is braced. by triangular braces, see Fig. 1. There is a central upward extension of the flange 27 which lies between the two longitudinal beams 12, as appears in the upper part of Fig. 6, and with that coperat- The inwarding with the bolt-s 33 lateral displacement of the forward end of the draw'bar is prevented. 4

One important feature of my invention is the removability of the draw bar. This is accomplished by removing the bottom plates or straps 50, 43 and 40, and then the draw bar construct-ion can be taken out downwardly. A new bar construction would then be substituted or the old one repaired and replaced. This is all done without changcured in place.

I claim as my invention:

A car having an end beam, a draw bar frame with the forward portion under said beam and having an upwardly extending plate abutting against the rear surface of said beam and having longitudinal openings in the upper and lower sides of said frame to the rear of said beam, a draw bar in said frame with an intermediate reduced portion under the end beam and with upward and downward extending shoulders on its inner end, a yoke secured to said draw bar and lying in said frame and projecting through the upper and lower openings in said frame and with the forward ends turned to over- 'ing the draw bar frame which remains se'- lap said shoulders, and a' carrier plate secured to said frame for supporting said draw bar so that the upper shoulder andv adjacent end of the yoke will project appreciably above the lower part of the end beam and the upper surface of the draw bar frame and the abutment plate on said draw bar is inv the path of the outward movement of said shoulder and yoke and said carrier plate is in the path of the outward movement of the shoulder and yoke on the lower side of the draw bar so `as to resist the withdrawal of the draw bar.

Tn witness whereof, l have hereunto af- ,ifixed my signature in the presence of the Witnesses:

G., H. BoINn, O. M. MCLAUGHLIN.
