DRAFT ARM ron RAILWAY cans.

To all whom t may concern.'

Be it known thatk I, CHARLES J. NASH, a citizen of the United States, and resident of Chicago, county of Cook, and vState oflllinois, have invented certain new and useful Improvements in Draft Arms for Railway Gars, of which the following is a specification and which are illustrated in the accompanying drawings, forming a part thereof.

In the construction of refrigerator cars it is the practice to apply below the car floor a layer of insulating material,-a fibrous material being used for this purpose and being held in place by a false flooring secured between the several sills. In the reconstruction of old cars having wooden center sills, by the application thereto of draft arms which extend up along the inner faces of these sills and arch over the car bolster, for the purpose ofstrengthening the underframing, difficulty has been encountered in providing for the introduction of such false flooring boards between the two center sills.

The object of the present invention is to provide a form of construction of draft arm of this type which will adapt it for use on. refrigerator cars and provide for the introduction of the insulating material be tween the center sills. This object is secured by' providing the upstanding flange of lsuch a draft arm with a suitable lateral flange or beading which will furnish a support for the. false ooring, without seriously decreasing the strength of the arm.

An embodiment of the invention is herein after described, and is shown in the accompanying drawings, in which# Fig. 1 is a detail longitudinal central section of the underl'raming of a car;

Fig. 2 is a detail plan view of the central portion of the underframing;

Fig. 3 is a view similar to Fig. 1, showing a modified form of construction; and

Figs. 4 and 5 are detail sections on the lines 4 4 and 5 5, respectively, of Fig. 3.

The improved draft arm has the usual body portion 10 located below the center sill 11, and being provided with draft and bufling shoulders 12, 13, and, in the embodiment disclosed, extending backwardly to and abutting against the front face of the bolster 14. The draft arm is further provided with an outstanding flange, indicated at 15, at the upper margin of the body7 portion 10, and

underlying and being bolted to the center sill, and with an upstanding flange 16 which lies along and bears against the inner face of the sill, this latter flange arching over the bolster, as indicated at 17.

An instanding bead or flange 18 is formed on the flange 16, bounding the upper margin of the latter from its forward end and continuing backwardly across the deeper portion 17 of this flange which arches over the bolster, and bounding the rearward portion of the flange 18 back of this widened section. A similar instanding bead or flange 19 bounds the upper margin of the widened portion 17 of the upstanding ange, the end of this bead, however, being spaced apart from the bead or flange 18 a sufficient distance to permit. the insertion of sub-Hoor boards 20 which rest upon the horizontal beads or llanges 18 of the two draft arms used in the car, which boards, together with the flooring 21 of the car, form a pocket within which is packed the insulating material 22.

In assembling the parts the two draft arms having been secured to the sills, the sub-floor boards 20 may be inserted from the Vrearward end thereof and shoved forwardly along the flan e 18, the insulating material being inserted etween the flooring and these boards as they are applied. In the modification illustrated in Fig. 3, t-he portion of the bead or flange 18 intermediate of the ends of the widened portion 17 of the upstanding flange of the draft arm is shown as being interrupted, taking the form of a. plurality of lugs 23V which, while forming an adequate support for the sub-floor boards 20, permit their more convenient insertion.

If desired the draft arm may be provided with a second instanding bead 24 at the base of the upstanding flange 16, and upon which may be mounted a second sub-flooring 25 to su port a lower layer of insulating material.

ack of the draft arm the flooring for carrying the insulating material may be supported upon strips 26, 27, nailed to the inner face of the sill, this feature, however, not forming a part of the claimed invention.

I claim is my invention- 1. In combination, a pair of draft arms, each having an upstanding flange for bearing against the inner face of a center sill, the adjacent faces of ysuch flanges being provided with `longitudinal beads for Supportbead throughout itsiength for siipportinga ing a sub-floor for Vcarrying insulating Inasub-Hoor for 'Carrying' insulating material i0 terial. i aIid each having a second instanding bead 2;11'1 combination, afpaii of 'draft arn'isV bounding theportion thereofzwhiohaarches each having an upstanding flange bearing over the bolster, theends ofthe last-namedv against the inner face of a center sill, and beads being vspaced apart from the firstarching over the car bolsteryeachange be- `named beads;
