Application filed January 14, 1910. Serial No. 537,984.

To all whom 'it may concern:

Be it known that I, HERMAN C. Primer., a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Im rovernent in Car-Underframes, of which the following is 'a specification.

My invention has for an object the providing of a wooden underframe with a reinforcing metallic underframe, both underframes being inthe line of draft and the reinforcing draft-sills" being permitted a wider spread than the4 reinforcing centersills and at the same time being rigidly secured to and constituting prolongations of said center-sills between the wooden centersills, and the said wooden center-sills being reserved intact intermediate the body- Eolsters; and the invention has for further objects such other improvements in structure or functions as may be found to obtain claimed.

In the accompanying drawings, forming a part of this specification, and in which like reference numerals indicate like parts in all ofthe figures, Figure 1 is a top plan view of the structure; Fig. 2 is a longitudinal sectional view on the median section line 2--2 of Fig. 1; Fi 3' is a sectional view on the line 3-3 of Ifig. l; and Fig. 4 is a sectional view on the line 4 4 of Fig. 1.

10, `10 Iare the woden center-sills of theA wooden underframe of the car, said sills extending the entire length of the car and being positioned in the line of draft, their spacing from each other being just suffi` cient to accommodate the draft rigging. 11 is one of the transverse body-holsters that immediatelyv support said sills and are bolted thereto b y the -vertical bolts 12.

13, 13 are relnforcing angle-iron centersills, positioned between the wooden centersills and extending, across the holsters, from the' inner end of the draft rigging at one end of the car to the' inner end of the draft rigging at the otherend of the ear.

are positioned with their inner angled faces toward each other and with the outer faces of their vertical webs bearing against the inner faces of the opposed wooden sills,

the said vertical webs of these angle irons being bolted to the said sills by the horizontal transverse bolts 14. The horiznntal flanges along the bottom of these angle-iron center-sills rest upon the upper face of each bolster.

15, 15 are reinforcing angle-iron draftsills, positioned between the wooden sills at each end of the car and extending from the end of the car to a point considerably to the other side of the adjacent body bolster, these angle-iron draft-sills being faced outwardly and having both their vertical webs and their horizontal flanges gained into the opposed faces of the wooden sills that they bear against. By reason of the gaining of these angle-iron draft-sills into the' wooden sills, the required reinforcement. of the ends of the wooden sills is effected without narrowing the free space required to accommoA date the draft gearing; and for a considerable distance both the angle-iron draft-sills and the angle-iron center-sills extend across the holsters, the said angle-iron draft-sills being permitted to underlap the angle-iron center-sills and additionally reinforce the Wooden sills in the vicinity of the holsters. The reserving of the free space required for the draft rigging may necessitate the gaining of the angle-iron draft-sills into' the ends of the wooden sills, as above stated; but the wooden sills are preserved intact,

and at the same time reinforced by the angle-iron center-sills, for nearly the entire length of the car intermediate the bodyholsters. The vertical webs of the angleiron draft-sills are bolted to the wooden sills by the transverse horizontal bolts 16. At either si de of each bolster, for about the space within which the angle-iron draftsills and angle-iron center-sills lap each other, there are secured below said angleirons, and closely abutting the opposite transverse edges of, the top part of' the bolster, the reinforcing tie-plates 17 17, the said tie-plates being riveted'to the orizontal flanges of the superimposed angleirons, by the rivets 18, and beingl extended outward under and supporting e wooden sills, spanning the entlre distance from the outer longitudinal ed e of one wooden sill to the outerI longitudinal edge ofthe other wooden sill. These tie-plates thus bind toether all of the angle-iron sills and brace t em against the transverse edges of the` bolster, and also additionally support'the wooden sills. To further tie the angle-iron center-sills together, there are spaced' along them at intervals, intermediate the holsters, the-accessory narrow tie-plates 19, riveted, by the rivets 20, to the under faces of the horizontal {ianges of said angle-iron centersills, and extending out under and additionally supporting the wooden sills. To further tie together the outer ends of the two angle-irons constituting each pair of angle-iron draft-sills, there are provided the downwardly flanged accessory tieplates 21, positioned to tie together the tops of the vertical webs of the mutually oposed draft-sills near the end of the car, each said tie-plate havin its `downwardly bent iianges riveted to t e, o posed inner faces|of the vertical webs o said draftsills, in a position high enough to clear the draft rigging that is adapted to be interposed between said draft-sills. The \t1e plates 17 and angle irons 15 and wooden sills 10 are further bound together by the vertical through-bolts 22.

It` is obvious that this construction permits extremely eifective reinforcing of the wooden underframe with the steel' underframe, when both underframes are required to he in the line of draft, as often happens in reinforcing the underframe of a wooden car that has been originally constructed with its wooden underframe in the line of draft; and at the same time the necessary space or spread to accommodate the draft gear .he tween the ends of the sills is preserved with out requiring the wooden sills to be cut away or gained out except at their ends, the said wooden sills being preserved intact for nearly their entire length intermediate the holsters. The connection of both underframes with the holsters is reinforced and strengthened Ato a maximum extent.

My invention 'is hereinabove set forth. as embodied in one particular form of construction, but I do not limit it thereto or to less than all the possible forms in which the invention as hereinafter claimed may he ernhodied and distinguished from any prior devices for like purpose.
