Specification' of Letters Patent.

Patented Dec. 28, 1909.

Application led August 26, 1909. Serial No. 514,791.

To all whom'tt "may concer'm` Be 1t known that I, 'lHEoDoRn 'W. REM- Mnns, a citizen of the United States, residing at St. Louis, Missouri, have invented a eertain new and useful Improvement in Car- Q Trucks, of which the following is a full, i

clear, and/ exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference beingliad to the accompanying drawings, forming part of this specication, in which- Y Figure 1 is a side elevation partly in seetion of the side frame of a ear truck of my improved construction.' Fig. '2 lis a plan view of the side frame seen in Fig. 1 and with parts broken'away in order to more clearly illustratethe same. Fig. 3 is an elevation partly in section of a modified form i the ribs, and when the parts are assembled of the side frame of a ear truck of my improved construction. F ig. 4 is a plan View of one end of the type of side frame seen in Fig. 3. Fi 5 is a cross section taken on the line 5-5 o Fig. 3.4

My invention relates enerally to car trucks, and more particu arly tothe side frames thereof, my object being to provide a side frame wherein the journal boxes form a part, the same being connected by rails or beams, and being provided with suitable guides for the ends of an H shaped truck bolster.

^ The principal 'objects of my' invention are; first, to producealight strong and durable side frame composed of a minimum number of parts which can be cheaply produced and' readily assembled and which side frames are characterized by the absence of'bolts andnuts, as is` well known, easily work loose in service; second, to 'pro- 4 duce a side frame, the various parts ofrially r ucingthe cost of manufacture of said fram third, to produce a side frame, on which a desirable form of body bolster which Sfiinterchangeable, thereby mate` can readily be used and to do away with the ,4

' 3, 4 and 5, the journal boxes l are provided usual stationary arch bar over the bolster,

and fourth, to form a truck with anv excepi tionally short wheel base.

To the above purposes, my inventionconsists in certain novel features of construction and arrangement of parts hereinafter more fully described and'claiined. Y

Referring by numerals to the accompany! i ing drawings, and particularly to the` form designates the journal boxes with the under sidesof which are formed integral, depending webs 2 which extend laterally as design ated by 3 and formed integral with the tops of these lateral extensions 3 are horizontally l disposed plates 4' on the upper surface 0f which are formed #suitable spring seats 5. lhe outer ends of the plates 4, are formed integral with the lower portions of the journal boxes l, and formed integral with the inner faces ofy said journal boxes and extending upward froni the plates 4 are vertieally disposed ribs 6 which extend above the tops of thejournal boxes and unite with `webs 7 formed on said journal boxes. 'Iliese ribs G forni guides for the lends 8 of the H shaped truck bolster 9, said ends being cut away as designated by 10 in order to receive plates 4 and the ends of the truck bolster,

are springs 12, the lower yends of which rest in the spring seats 5. Uniting the journal boxes 1, is a pair of beams l13 preferably in the form of commercially rolled channels arranged parallel, with their ends fitted of side frame illustrated iii Figs. 1 and 2, 1

against the depending webs 2 and exten-V sions 3, and said channels are rigidly fixed- 'to said webs and lateral extensions by means of rivets 14 or like fastening devices. The

tops of the channels 13 are eut away at the Aouter ends as designated by 15 1n order to accommodate the lower portions of` the journal boxes 1. Thus it will be seen that this form of side frame is made up of but four main parts, namely, the pair of journal boxes and the pair of channels, said parts being rigidly united by means of rivets or the like.

In the forni of side frame shown in Figs.

permit the location ofspring 17 between them. 'lhe ends of an H shaped truck bolster rest on the springs 17, said ends beving guided vertically by the webs 16. A

pair of beams 19 preferably in the form of commercially rolled channels are arranged between the lower portions of the journal boxes 1n and the ends of said channels are rigidly fixed to the lower portions of the webs 1G preferably by means of rivets 20. Thus each pair of journal boxes l is connected, and to further strengthen the structure, a flat plate 21' is positioned against the under side of the lower flanges of the channels 19 and against the inner sides of the journal boxes l, the edges of which flat plate are connected to Vthe lowermost ilangcs 'of the channels 19 by means of rivets or like fastening devices. AThe ends of this flat plate 20 arc bent around flanges 22 formed on the lowerouter corners of the journal boxes l, and are iixcd thereto by means of rivets or the like. In this form of side frame, tive main pieces are utilized, viz, a pair of journal boxes, pair lof channels, and the flat plate.

In ordinary construction :it will not be necessary to tie the two side frames of each truck together, but if such construction is desired, said side frames can be united by means of a transversely disposed flat plate, a channel, or a pair of angle bars, as shown by dotted' lines 1n Fig. 1.

Side frames of my improved construction can be very easily and cheaply produced as they are composed of but a small number of parts which are easily assembled, combines great strength with rigidity and provides a j construction. whereinl all small parts, such as bolts and nuts are dispensed with, which small parts as is well known, tend to work loose in service.

I claim:
