To a/ZZ whom it may con/cern,.-

zen of the United States, residing at Chicago,

in the county of Cook rand State of Illinois, have invented new and useful Improvements in Sills for Skeleton Car-Frames, of which the following is a full, clear, concise, and exact description, reference being had lto the accompanying drawings, forming a part of vthis specification.

. M invention relates to railway-cars, and particularly to the manner of constructing the frame of the same. l

One of the objects of my invention is to provide a sill for a car-frame which shall have maximum strength with minimum 'amount of material and which shall be so constructed that the same vmay be readily accessible on all sides for the purpose of connecting the other parts ofthe car thereto. y

I have illustrated my invention in the accompanying drawings, in which- Figure 1 is a artial side view of the car, showing a position that my sill assumes in` the car. Fig. 2 is an enlarged detail crosssection of a portion of a bottom, taken on line 4- 4 of Fig. 4, showing the .manner of constructing my sill and the manner of bracing the saine.l Fig. 3 is a detail perspective view of my sill and otherv structural parts of the car. Fig. 4 shows a' modification of my sill construction. Fig. 5 shows another modification of my sill construction; and Fig. 6 is a partial plan view of my car, showing the skelet n construction of the bottom thereof.

Int e preferred embodiment of my invention the sills of m car lare constructed of pressed-steel U -s y a' ed members. rIfhese members are preferab y formed from twoA L- shaped Imembers 1 and 2, having adjacent sides 3 and 4 overlapping and suitably secured together, as illustrated in Fig. 2. The L-shaped member which forms the outside of the sill preferably has the sideortions SiO thereof ofl greater length than the ot er side whereby van upwardly-extending flange 5 -is formed. The side 4 of the L.- shaped member 1. is also of greater length than the side 3, whereb a flange 6 is formed on the bottom of the sil I At intervals along the top of the sill the two sides are braced and connected together by'nieans of a T- shaped brace 7, havin a downwardly-'extending Hange 10, pre erably formed from cast-steel. The head 8 of this block is secured to the inside of the outer vertical side portion by rivets orother means and has a portion 9 thereof extending up be ond the upper edge of the side of the sill` T e downwardly-extending flange 10, formed up'on the stem 11 of the T-shaped tie-block, is attached to the `outside of the innervertioal side portion of the sill by suitablerivets or other securing means.

The two side sills of the'car are constructed in lthe manner above described and at suitable intervals are connected together by means of a bottom tie 12, which extends between the same and is fastened by suitable rivets to the flanges 6 of the sills. As an ad` ditional means of supporting and connectingy the side sills a truss 13 is arran ed between the two side sills immediately in ront of each of the bottom ties 12, and this truss is preferably of the construction shown in Fig. 2,

having a horizontal portion 14 riveted or otherwise secured to the under side of theI The truss extends stem 11 of the T-block 7. downwardly beneath the center sills 15 and 16 of the car and has riveted'thereto flat supports 17 and 18, which extend lon itudinally of the car and aid in carrying an bracing the center sills 15 and 16, to which' the bottoms of these sillsare attached. These ycenter sills are preferably constructed of T,-

beams, as shown in Fig. 1. .Between the side sills and on top of the same horizontal members 19 of the truss 13, which also constitute floor-ties, are laid at suitable intervals, and these ties are riveted at their central point to the tops of the center sills 15 and 16 and at their ends tothe tops of the stems 11.

The ends of the cars are constructed of car end sills 26 of lsubstantially the same construction as the side sills and secured thereto b means ofthe an le-pieces21. These end si ls extend inwar ly toward the center of` the car to the center sills 15 and 16, to which they are also secured. The platform side sills 22 of the car are also constructed in substantially the same manner as are the side sills ofthe car and are secured to the end sills by suitable angle-pieces 23 at one end and to the platform end sills'24 at their other end.'

The platform end sills are also of the same general construction as the side sills of the car. It will be noted that the center sills 16 IOC and 17- of they car extend the entire length thereof, including the length of the platform. The sides of the car may be constructed in 'any suitable manner; but as my peculiar construction of sill makes one manner ofconstructing the sides ofthe car particularly advantageous I prefer-to construct the same in this manner. At'regular intervals vertical posts are secured between the two vertical members ofthe sills by means of rivets or bolts. These vertical posts provide means to which the sides et the car may be rigidly'attached. In one form., which isi-particularly advantageous in constructing passenger-cars, I'provide longitudinally-extending wooden rails or strips 26, which are bolted to vertical posts 25, and wooden strips 27 which are olted at the bottom of the side sills. The veneer 28 of the sides of the car is attached to these strips in any suitable manner. This is only one manner of constructing the sides of the car, and any other manner may be used, depending upon the use to which the car is to be placed. For instance, if vdesired to construct an all-steel car having an outer veneer of wood, Athe steel sheeting may be secured directly to the vertical posts and side sills and the wood veneer secured thereto. Also the bottomV lining of the car may be formed of steel sheeting as well as the inner sides. If desired, a floor and side veneer may be placed overv the steel lining. In freight-cars the sides may be sided up With wood or steel sheeting, depending uponthe malner in which the' car is intended to be use While I have described one form of my invention, it will be understood that I do not Wish to limit myselfA to the s ecific details thereof and that the U-shape sills may be formed'in any other manner, if so desired.

I have described my'sill as being formed of pressed steel, this being the usual form of steel used in its construction and havin been found the mest advantageous. It Wil be understood thatv my sillsmay be formed from members made in any desired manner* as, for instance, by rolling, forging, &c.

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

l.' A sill for skeleton car-frames comprising .a steel substantially U-shaped `member formed of two substantially L-shaped members having adjacent sides overlapping and suitabl tiedA together, one 'of the vertical sides o said member being longer than the opposite vertical side of said member.

2.' A sill for skeleton car-frames, comprising a steel substantially LJ-shaped member formed of twosubstantiallyL-shaped members, having adjacent sides overlappin and suitably tied to ether, one of said sides eing longer than the opposite side, whereby a projecting flange is formed.l

3. A sill for skeleton car-frames, comprising a substantially U-shaped steel member formed of two substantially L-shaped members having adjacent sides overlapping and suitabl tied together, one oi the vertical sides o said member being longer than the opposite vertical side, and one of thehorizontal sides of said member being longer than the opposite horizontal side.

4. A sill comprising a steel substantially U-shaped member formed of two substantially L-shaped members having adjacent sides overlapping, one of the vertical sides of said member being longer than the opposite vertical side, and oneof the horizontal sides being longer than the opposite horizontal side, and a T-shaped tie-block for tying and bracin the disconnected ends of said U- sha e member, the head of said T-shaped tielock being secured to one of said L-.

shaped members, and the stem of said T- shaped tie-block having a flange arranged to be secured to the other ofsaid members.

In Witness whereof I have hereunto subscribed my name in the presence of two witnesses.
