JOHN J. HENNESSEY, OF MILWAUKEE, WISCONSIN.

CAR-FRAME CONSTRUCTION.

Specification of Letters Patent.

Patented Jan. 14, 1908.

Application led June 4:, 1907. Serial No. 377.178.

To all whom it may concern:

Be it known that I, JOHN J. HENNEssEY, of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Oar- Frame Construction, of which the following is a specification.

My invention relates to a new and improved car-frame construction and more particularly to the center-sills and body-holsters entering into said construction and the manner of connecting said parts.

The prime object of the present invention is to provide a simple and efficient construction in which the body-bolsters and centersills may be readily assembled and in which the parts and especially the tension-member of the bolster are made sufficiently strong to withstand the strains to which they are subjected in service.

In the accompanying drawing, which illustrates anv application of my invention, Figure l, is a part side elevational and a part sectional view of a car-frame construction embodying my invention, Fig. 2, a plan, partly in section; Fig. 3, a transverse section taken on line 3 8 of Fig. 2 5 Fig. 4, a broken elevational view of the central portion of the body-bolster; and Fig. 5 a perspective view of the bolster reinforcing plate.

As illustrated and as preferred, the bodybolster is made of cast-steel and comprises a tension-member 1, a compression-member 2, and a connecting web 3.

Located centrally of the bolster and extending downwardly through the tensionmember are two transverse separated recesses or pockets 4, adapted to receive the center-sills 5. These recesses are each bounded by a bearing-member or seat 6 and side extensions 7 and 8 all projecting laterally from the web 3 of the bolster and, as shown, they extend for a slight distance beyond the tension-member.

9 designate upwardly projecting and trans` versely extending flanges each formed on one side of and adjacent to a recess. The tension-member is further provided with two longitudinally disposed flanges 10 extending from one recess tothe other.

The center-sills, as illustrated, are of channel form, other 'suitable forms, however, may be employed, and are provided with slots or openings l1 through which a bolster reinforcing plate or member l2 is passed. Plate 12 is preferably of about the same width as the tension-member of the bolster and when in position rests between the flanges l0 and bridges the spaces or cutaway portions of the tension-member. By this construction I replace the metal taken from the tension-member in forming the recesses and provide a continuous strong tensionmember. The bolster reinforcing plate is secured to the tension-member by means of rivets 13 and is formed with channels or grooves 14 each adapted to receive one of the transversely extending flanges 9.

After the parts are assembled the respective center-sills are preferably secured to the seat 6 and to the side extensions 7 by means of rivets 15, as clearly shown by the drawings.

What I claim is:

l. In a car-frame construction, the combination with center-sills having slots formed therein, of a body-bolster having separated recesses or'pockets to receive the center-sills, and a plate having a laterally extending groove, said plate extending across the recesses and through the center-sills, and a transversely extending ange on. the bodybolster adapted to iit into the groove of said late. p 2. In a car frame construction, the combination with a pair of center-sills each having a slot formed therein, of a body-bolster having disunited recesses to receive the center-sills and formed with an upwardly projecting flange adjacent to a wall of each recess, and a plate formed with grooves adapted to receive the said flanges, said plate attached to the bolster and extending across the recess and through the center-sills.

3. In a car-frame construction, the combination with centre-sills having slots formed therein, of a body-bolster comprising a tension-member, a compression-member and a web joining said members, said tensionmember having disunited cut away portions to receive the center-sills, an integral webportion located' between the cut away-portions, and a plate for replacing the cut away portions attached 'to the tension-member and extending through the slots of the centersills.

4. In a car-frame construction, the combination with center-sills provided with slots, of a body-bolster having separated recesses to receive the center-sills, an integral web-portion located between the recesses, longitudinally extending flanges 10 projecting from the tension-member of the bolster,

a reinforcing plate located between the said flanges and extending across the recesses and through the slots of the center-sills, and means for securing the plate to the tensionrnernber.

5. In a car Jframe construction, the combination with center-sills having slots formed therein, of a body-bolster having separated recesses to receive the center-sills, upwardly rojectingvlanges adjacent to each recess, ongitudinally extending flanges, and a plate bridgingl the recesses and extending through .thecenter-sills, said plate located between the longitudinally extending flanges and formed with ineans for engaging the upwardly projecting llanges.

6. In a car-frame construction, the conibination with a center-sill having a slot 'formed therein, of a body-bolster having a recess or pocket to receive the center-sill, a

plate provided with a `laterally extending groove, said plate extending across the recess and through the center-sill, and a transversely extending Aflange on the body-bolster adapted to lit into the groove of said plate.

7. In a car-'frame construction, the conibination with a center-sill having slots formed therein, of a body-bolster having separated recesses or pockets to receive the center-sill and an integral web-portion between the recesses or pockets, and a plateY attached to the tension-member of the bolster, said plate extendingacross the recesses JOHN J.
