METALLIC UNDERFBAME FOB RAILROAD-CARS.

Specification of Letters Patent.

I Patented July 14, 1908 Application filed January 20, 1908. Serial No. 411,746.

' To all whom-it may concern:

Be it known that I, HENRY TEssEYMAN, a citizen of the United States, and aresident of the city of Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Metallic Underframes for Railroad-Cars; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to'which it appertains to make and use the same, reference being had to the accompanying drawings, and to the numerals and letters of reference marked thereon, as forming a part of this specification.

My invention relates to metallic underframes for railroad cars; and has for its obj sets to provide an improved and simple con 'ing the drawbar in its position therein and the arrangement of the several features covering my improvements; Fig. 2 a broken pers ective view of the draw-bar buffer cast ing, ig. 3ja broken perspective view of the draw-bar carry-iron; Fig. 4 a pers ective view of the buffer reinforce casting; ig. 5 a cross-sectional view of the side sill as applied to coal cars and showing a stake for supportin the sidewalls thereof; Fig. 6 a broken si e elevation of Fig. 5; Fig. 7 a cross-sectional view of the side-sill as applied to box cars Fig. 8 a cross-sectional view of the sidesill as applied to flat cars; Fig. 9 a broken perspective view of the connecting casting to which the draft-sills, the bolster and the center-sill are rigidly connected and which when so connected form a single structure, and Fig. 10 is a broken plan view showing I the manner of'connectingthe center-casting and secured together by up with the bolster and center-sill, Figs. 2 to 10 inclusive being of larger scale than Fig. 1.

While in the drawings (Fig. l) but one end of the under-frame is represented it is to be understood that both ends thereof are alike, therefore, in'describing the invention separate reference to such parts as are dup1icated at the opposite'end will not be necessary, andit is to be further understood that in making and assembling the various parts any desirable means usual in such practice, may beemployed 'for securing the same in their respective places.

' In the said drawin s similar reference let- 'ters and numerals nidicate corresponding parts in all the 'fi ures thereof.

A represents t e center-sill, which is made in the form of a box-girder comprising two side-channels, 1 and 1 spaced a suitable distance. apart and connected together by up-' .per and owerplates 2 and 2*.

. B is a bolster and sillconnecting-block comprising a casting of such form and so strengthened by ribs and flanges as toproduce the requisite amount of strength with a minimum amount of material and which is provided, at its center, with an integrally formed hollow sleeve 3, through which asses further provided with wings 4-4 5-5;

6- 69; 7 and 7, this casting. constitutes a part of the bolster, designated'as O and which,

ko the center-sill, is made up of side-channels 8 and 8, there being four channels to each bolster, spaced a suitable distance apart the usual king-bolt, not shown, and w ich is p or and lower plates 9 .and 9, at opposite si es of the cast-.

sill A extend from bolster to bolster, their ends being secured to the wings 6-6 of the casting B while the upper and lower plates, 22 extend across and beyond, the said casting and are secured to the flanged portions of'channels 10 and 10 which constitute draft sills,- the rear ends of which are secured to the wings '77 of said casting, and thus the center sill, bolster and draft sills when assembled and united as above described constitute a single structure of great strength and efficiency, besides being extremely advantageous in the construction of the underframe and in making repairs thereto.

The side sills D are each composed of two 2 bars, 11-12, so secured together as to form a channel on the inside, and a double, longitudinal, flange or shelf on the outside upon which rests a timber E which is fastened to the 2 bar 11 and to which the floor F, siding G, and any desirable frame-work extending above the floor may be secured;

and to which, in coal cars the stake-sockets H, carrying stakes I may be secured, this simple and inex ensive manner of constructing the side-sil s, coupled with additional strength contributed by the double, 'longitudinal, flanges at the center avoids the necessity of securing to the sill an additional longitudinal shelf or rest for the timber E and provides a most desirable structure for the purposes intended.

J re resents the end-sills, to which the side-sil s and the draft-sills are united, anglepieces (shown in Fig. 1, by dotted lines) being employed in making the union of these parts, and the frame being braced by suitable race-members which extend from the outer corners of the same to points where the bolster and draft-sills meet.

At or about the center of the end-sill its lower flange and a part of its web are cut away to form an 0 ening to receive the draw bar 13 of the dra t-rigging L, the draw-bar being supported by the usual carry-iron M, secured at its outer-ends to the lower flange of the channel constituting the end-sill and,

. intermediately, by bolts which ass through the upper and lower flanges of t 1e said chan nel through recesses 14--14,formed in a buffer-casting N, located between the flanges of said channel and secured thereto for the purpose of contributing strength to the structure at this point; the lower portion of this casting being cut-away to re ister with the opening formed in the end-sill to receive the drawbar. A re inforce casting O is located above the draw-bar and secured to the draft-sills,

preferably byrivets, and to the end-sill b olts which ass therethrough and throug the center-sill are connected therewith to form a single structureand the convenient arrangement of all the parts whereby same can be removed without disturbing others,

which as hereinbefore stated is of great advantage, not only in the construction of new work but. also in making repairs, also that the bufler-casting can be removed and replaced independently of and without disturbing any of the other parts of the structure.

It is obvious also that the details of construction may be departed from in various ways without de arting from-the spirit of my invention an therefore, I do not limit the invention to the exact details which I have illustrated andv described herein.

Having thus fully described my invention, what I claim and desire to secure by Letters Patent, is

1. In a metallic under-frame, a bolster composed of a plurality of sections comprising a Cpair of channels spaced apart and connecte by upper and lower plates, a connecting-block intermediate the said sections and secured thereto, in combination with means for connecting draft-sills and a center-sill 1 with said connecting-block.

2. In a metallic-under-frame, the combination with side-sills, of channel-shaped endsills, drawer-bars located and operating in openings formed by cutting away a portion of the webs and lower flanges of said channelshaped end-sills, bufler-c'astings located between the flanges which form the channelshaped end-sills and which are secured to the latter adjacent to the openings for the draw bars therein, draw-bar carry-irons secured to the said lower flanges of the end-sills below said openings, and recesses formed in said buffer-castings for the passage of bolts from the upper flanges of said end-sills to and through the lower flanges thereof and through said carry-irons.

3. In a metallic under-frame, the within described buffer-casting having the. recesses formed therein for the passage of bolts therethrough and rovided with a suitable passage-way for t e reception and operation ola draw-bar.

4. In a metallic under-frame, the combination of side-sills and end-sills, with draftsills located between the side-sills, draw-bars located between the draft-sills, buffercastings secured to the end-sills, and reinforce castings located at the back side of the endsillsabove the draw-bars and secured to the draft-sills and end-sills.

5. In a metallic under-frame, the ithin described side-sills each comprising a plurality of 2 bars secured together so as to form a longitudinal shelf or bearing on the outside thereof, in combination with a timber-piece resting thereon and secured to the side-sill and constituting a member to which may be secured the floor and upper frame-Work of the car, and end-sills to which the side-sills are connected.

In testimony that I claim the foregoing as in the presence of two subscribing Witnesses this 17th day of January, 1908. I

HENRY TESSEYMAN.
