novel tie 'bar for use -in connection therewith.

In the use of car trucks it is customary to employ a side frame composed of upper and lower arch bars, columns and a tie bar, the arch bars at their ends resting on a journal box, the tie bar fitting underneath the journal box. Journal box bolts are then employed to secure the structure in place. ltn many instances a one piece tie bar is employed -that is, a bar extending from one journal box to the other and being secured to the lower arch bar of the side frame. However, in many instances short tie bars are employed, these being secured to a portion of the side frame by means of a bracket. However, the attaching bracket has heretofore been projected at an acute angle from the lower arch bar. lln-such a construction riveting of the tie bar is not only difficultbut must be performed by special machinery and but two rivets may be used.

lfn the present construction the attaching bracket has been projected at right angles from the lower arch bar, the attaching end of the tie bar being bent slightly into line therewith. ln this way the rivets used in attaching the tie bar to the bracket may he applied by any ordinary riveting appliance. Furthermore, four rivets may he used.

My invention will be morereadily understood by reference to the accompanying; drawings, wherein-- Figure 1 is a side elevation of a side frame and tie bar such as contemplated by me; Fig. 2 is a section on the line 2, 2 of'l 'ig. .1;

and Fig. 3 is a fragmentary View of tie bar attaching means as heretofore employed.

with the side frame, serve a point combination, upper and lower are columns, tie bars, iltflftCl'llflfl bra Referring more particularly to the drawings, it is seen that in the preferred eurbodiment of my invention construct a side frame of one piece of cast metal. the frame comprising top arch bar 10 nn arch bar 11- and columns 12. The ends of the side frame in practice rest upon journal boxes 13, and tie bars conu the lower portions of the journal bones side frame. Brackets 15,1)rc'lerably tachment for the tie bars. 'lhese crack... extend atright angles to the lower arch bar and are preferably strengthened by 2 l6. Fourrivets l? are en'iployed in ing the tie bar to the ln-acltet. it vrh seen that as the rivets extend in a 111 parallel to that of the lower arch her. they may be inserted and driven with ease. whereas in the construction shown in l igr. 1:? the distance between the points A and B is slight that a rivet is inserted with difficulty and but-two rivets may be used. lFnrthermore, a special riveter must be employ for the reason that the lower arch bar cittends directly over the rivet holes.

It is believed that there disclos i herein a construction providi for the maximum strength with a minimum Wei ht of material. l urthcrmore, the riveting: peration may be performed with the greatest facility,
