SILL OR STRINGER FOR CARS.

SPECIFICATION forming part 0f Letters :Patent N0. 622,971, dated April 1 l, 1899.

. Application filed February 2.7, 1899. Serial No. 706,979. (No model.) I

T0 @ZZ whom, it may concern:

Be it known that I, RICHARD W. OswAnD, a citizen of the United States, residing at Bloomsburg, in the county of Columbia and State of Pennsylvania, have invented certain new and useful Improvements in Sills or Stringers for Cars; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invent-ion relates to improvements in stringers or sills for cars, and particularly to those which are made of metal beams orbeams and plates suitably secured together.

It consists in angle beams or irons suitablyr arranged with respect to each other and bolted together to form a car sill -or Stringer and brace-plates also bolted to said angle beams or irons to strengthen the said sill.

It also consists in certain other novel constructions, combinations, and arrangements of parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 represents a side elevation of a sill constructed in accordance with my invention. Fig. 2 represents a cross-section through the same near one end thereof. Fig. 3 represents a crosssection of the same near its central portion. Fig. 4 represents a side elevation of a sillin which the upper angle-bar is elevated at the center. Fig. 5 represents a sectional View of the same near the end thereof. Fig. 6 represents a central cross-section of the said sill, and Figs. 7, 8, and `9 represent detail crosssections showing slightly dilferent arrangements in the arranging of the angle beams or irons with relation to each other.

In producing a strong and durable sill for cars it is desirable to use merchantable material therefor-that is, material which is easily obtained in the market, such as anglebeams and straight plates which are rolled and kept in stock for various uses. My invention contemplates the use particularly of angle irons or beams together with strengthening-plates, the construction being such that it is not necessary to manipulate the parts to any great extent.

As seen in Fig. 1 of the drawings, the sill l may be composed of an uppenmember 2 and a lower member 3, which are preferably angle-iron bars or beams and, as seen in Fig.

2, are preferably provided with deeper vertical flanges than horizontal ones. The vertical iianges are placed together, the horizontal lianges being turned in opposite directions from each other. At each end of the beams the vertical flanges are bolted together, as seen in the drawings, while'the central portion of the lower beam or member 3 is preferably depressed or bent downwardly, so as to separate the members to some extent at this point. In order to bind the members 2 and 3 at this point and brace them with respect to each other, I apply in the central portion of the sill strengthening angle irons or plates, as 4 and 5. As seen in Fig. l, the angle-iron 4 is made to lie flush with the upper surface of the upper member 2, its vertical flange being cnt to iit the upper edge of the vertical flange of the lower member 3. The strengthening-iron 4 is then securely bolted to the upper member 2. Upon the other side of the sill a similar plate 5 is applied, which is bent to correspond with the shape of the lower member 3 and has its vertical flange cut to 4fit the lower edge of the upper member 2. This braceiron 5 is then bolted securely to the lower member 3. The construction just described is clearly illustrated in Fig. 3 of the drawings, in which the relative positions of the parts can be clearly seen.

While the angle-beams forming the upper and lower members of the sill maybe applied directly to each other, as' above described, yet it will be apparent that I may interpose brace-plates between the two Aangle-irons to hold the structure together.

As seen in Fig. 4 of the drawings, the sill may be composed of upper and lower members 7 and 8, made of angle-iron, as previously described with respect to Fig. l. These an gle-irons may be arranged with their flanges in opposite directions from each other, as seen in cross-section in Fig. 7, or their horizontal iianges may extend in the same direction, as seen in Figs. 5 and 6. In constructing a sill in this manner I preferablyarch the upper member 7 in the center and depress the lower member 8, as clearly seen in Fig. 4t. The

ends of the sill are broughttogether, and a brace-plate, preferably of flat metal, as 9, is interposed between the vertical flanges of the members '7 and 8 and the parts securely bolted A brace-plate, as lO, is also applied in the central portion of the sill and interposed between the upperand lower members thereof, the said brace-plate l0 being securely riveted or bolted to the upper and lower members to brace them with respect to each other. l

It will be apparent-that the angle-irons could be"arranged in several different positions with respect to each other and with respect to the intervening brace-plates, the angle-irons being upon opposite sides of the brace-plate, as in Fig. 7, their iianges extending in opposite directions from each other, or they may be arranged upon the same side of the brace plates, as seen in Fig. S, their iianges extending in the same direction. The angle-irons might also be arranged as shown in Fig. 9, in which they are applied to both sides of the said plates at the top and bottom, the horizontal flanges of course extending in opposite direct-ions from each other, all within the spirit of my invention.

It will be evident from the above description that I am enabled to combine angleirons and brace-plates in such a manner as to form a simple yet strong and inexpensive sill and beam for cars or other purposes and one that can be produced from material which is commonly found in the markets.

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

l.v A sill for cars comprising angle-irons having their vertical iianges riveted together and brace-plates cut to I'it the' members of the sill and riveted so as to brace them with respect to each other,substantially as described.

2. A sill for cars comprising upperand lower members formed of angle-irons, the vertical iianges of said irons being bolted together at ber and the lower edge of the upper member,

the said brace an gle-irons being securely riveted in place to brace the structure, substantially as described.

4. In a sill for cars, the combination of upper and lower members comprising angleirons having their vertical'iianges riveted together at their-ends, brace-plates interposed between lthe said vertical anges, said upper and lower members bein g separated centrally, and a brace-plate interposed between them and bolted to the vertical flanges of each for strengthening the parts, substantially as described. l

5. Asill for cars comprising upper and lower members formed of angle-beams, brace-plates interposed between the vertical dan ges of the said beams at their ends, the parts being riveted together, the upper member of the said sill being arched upwardly while the lower member isdepressed, a brace-plate connecting the vertical flanges of the upper and lower members at their central portions, being bolted to the upper angle-iron upon one side of its vertical ange, while it is bolted to the lower'member upon the other side of its vertical ange, substantially as described.

In testimony whereof I hereunto affix my signature in presence of two witnesses.
