TRUCK SIDE Application filed April '29, 1920, Serial No. 377,441.

- To a'ZZ whom it may concern:

it known that I, lVAL'rE-n A. LUCAS, a citizen of the Uited St: (es, residing at Hawthorne. in the count;' of Passaic and State of New Jersey, have invented certain new and useful Improvements in Truck Side Frames; and I do hereby declare the following 'to be a full, clear. and exactdescription of the invention, such as will onable others skilled in the art to which it appertains to make and use the same.

The invention relates to trucks for railway vehicles and more particularly to new and useful improvements in the construction o t side frames for arch bar trucks.

The principal object of invention, broadly considered, is to strengthen and simplify the construction or arch bar side frames. To -thisend the primary feature of the invention consists in a combined arch bar and journal. box tie n'iemberof simple and novel form.

Other features of the invention will hereinatter aopcar from-the detailed description oithe single embodiment or" myinvention, which is shown in the accompanying drawings, wherein,

Figure 1 is an elevational View of a symmetrical portion of a truck side frame embodying my invention.

Figure 2 is a top View of the combined tension or lower archmembers showing the same in assembled position, the upper arch member and the strut column being omitted.

Figure c a sectional view.

Figure 4 is an end view of the upper portion of the side frame showing the relation or" the arch members to the journal box seat.

Throughoutthe specification and drawings like parts are designated by like reference characters.

Fhe trucl; side frame l is provided with a top arch member which is conveniently formed as a rectangular bar 2, and a lower arch member which preferably comprises a pair of flanged bars 3, 3. interposed between the arch members intermediate the ends thereoi is a strut member at which has for convenience been illustrated as comprising a pair or columns 5 connected by the conventional form. of spring plank 6; only one of the columns being illustrated in the drawings. it being understood that the truck,

side frame is symmetrical on the center line.-

the upper arch bar to the said RenewedT/[ay 25, I923.

The ends of the arch members 2 and 3 are connected to a journal box seat 7, the said seat iormmg a support for the upper wall oi the ournal box 8. The ourn-al box seat illustratetd in the drawings preferably 00111131 1883 a hollow box like casting having alined holes in the top and bottom v s9 to receive the journal box bolts "10, the said bolts passing through and firmly connecting seat. The lower arch members are preferably riveted to theside webs "l1 otthe said seat, as clearly shown in Fig. 4

The lower arch or compression members 3 are preferably formed as Z-bars having their upper flanges 12 extending towards each other and their lower langes geritending laterally of the truck frame in opposite directions. To conveniently form the journal lJO-X tie bars I preferably cut through the web 14 of each Z-bar from the ends of the said barsto point near the adjacent strut column. After the z-ba-r is cut the lower flange is bent away from the remaining por ion of-each .bar 3 so that the end portions of each Z-bar arespacec l apart a distance approximately equal to the height of the journal box 8 plus the height of the journal box seat 7. The cut through the web of each Z-ba-r is preferably made in line w th the upper face of cach flange 13 for the major portion of the cut and at least adjacent the outer end portions thereof. By this means 1 form at each end of the said arch bar 3 a substantially fiat plate 15b 7 These plates are then bent inwardly as shown at 16 so that the adjacent ends of the plates 15 formed from the Z-bars will overlap and underlie the ournal box to which they are connected by means or" the journal box bolts 10. The said bolts are adapted to pass through alincd openings in both of the adjacent plates 15, said plates being held to the journal box by the nuts 17 providedon the ends of the bolts 10. By making the tie members integral with the lower arch members the number of parts in the truclrside frame is materially reduced and all possibility of a loose connection between these members is avoided, thus greatly strengthening the side frame.

l/Vhile I have illustrated and described thecombined tension and journal bozrtie bars as being formed from Z-shaped members, I

do not intendto be limited to this form of member, and wish it to be understood that other forms of rolled shapes may be advanta eously employed in this connection.

l-Iaving now full described my invention, what I claim and esire to secure by Letters Patent is 1. A. truck side frame comprising a top and a plurality of spaced flanged bottom arch members, and means for uniting said members adjacent the journal boxes, each of said bottom arch members being made from an integral bar split in a suitable manner to form journal box tie members therefrom.

2. A truck side frame comprising a top and a plurality of bottom arch members, means for uniting said members adjacent the ends thereof, and journal box tie members integral with each of the bottom arch members, the end portions of adjacent tie members being adapted to overlap.

3. A truck side frame comprising a top and a plurality of flanged bottom arch members, one flange of each of the said bottom members being spaced from the end portions thereof and being adapted to form a journal box tie member.

4. A truck side frame comprising a top arch bar and a plurality of lower arch members, the latter each being formed from a Z-bar.

5. A truck side frame comprising a top arch bar and a plurality of lower arch members, the latter each being formed from a Z-bar the upright webs thereof being spaced apart and the upper flanges thereof extending toward each other.

6. A truck side frame comprising a top 1 rara /2 7. A combined arch and journal box tiebar for trucks comprising a flanged member havlng a unlted central portion and divlded end portions, the said divided end portlons being adapted to be spaced apart to receive a journal box between the same, the cross sectional area of the said end portions being the same as the cross sectional area of the united central portion.

8. In a truck side frame, the combination with a compression member, a journal box connected thereto and a strut, of a plurality of tension members engaging said strut and connected to said journal box, each tension member comprising a beam having a plurality of flanges extending laterally from the web, the said web being cut for a portion of its length whereby one. of said flanges may extend above and the other below the said journal box, and means for connecting each of said flanges to the said journal box. V

9. A combined tension and tie bar for truck side frames, comprising a beam provided with a plurality of flanges extending from the upper and lower edges of the web thereof, said flanges diverging from a point adjacent the center of length of the said beam and adapted to extend above and be low the journal box. 1

In testimony whereof I afiix my signature.

XVALTER ARNDT LUCAS.
