To aZZ-whmn it may concern:

Be it known that I, THOMAS H. SYMING- iron, a citizen of the United States of America. residing at the city of Rochester, county of Monroe, State of New York, have invented certain new and useful Improvements in End Constructlon, of which the following is a specification.

end of the car.

This invention relates to a plate and angle construction to be applied to the sills of wooden cars. i

The replacement of antiquated and worn out draft gears on the old Wooden frame freight cars is at present an important item in railway equipment and the application of the modern types of draft gears to the wooden frames in a manner which will en-- able them to withstand the-increased buffing and drawing stresses to which these parts are subjected under modern conditions of heavy trafiic, involves various problems of 'the' greatest importance. Great difficulty is encountered in so attaching the cheek plates to the wooden sills that the sill will not be split and shattered with the result that the cheek plates become loose or detached .and the draft gear fails completely.- Also as the draft gear is mounted below the sills, there is a tendency for the sills to give downward at the ends and break at the bolster.

' the depending portion of the draft plates, bolts being ordinarily used for this purpose. In the present instance, a beam built 'up of plates and angles or channels 1s preferably substituted for the old wooden bolstern The draft plates referred to, as carrying the cheek plates, are reinforced along the top and bottom edges of the cheek plates, by means of angles or other stiffening members, andthese angles, part or all of them in the preferred form of the invention, as' Well as the plates themselves, Wl'llCll arenotched or shouldered for this purpose, abut against the bolster and at the front, and the"; top portion of the draft plate, which projects upward between the sills, abuts against the front cross-sill. At the rear, the draft plates extend over and beyond the bolster. belngu'einforced at the bolster to prevent breaking of the sills over the bolster as is the tendency of the former structures.

Preferably the cheek plates which receive the drawing and buffing stresses, are secured to the depending portion of the draft plates over the reinforcing members previously referred to, and the rivets or bolts pass through the draft plates, cheek plates and angle irons so that the whloe structure is exceedingly rigid, durable and permanent and cannot be displaced except by the destruction of the entire under frame.

A draft gear construction applied to a wooden under frame by means of the device of my invention, is shown in the accompanying drawings, in which Figure 1 is a view half in plan and half in horizontal section on the line 1, 1 of Fig. 2; Fig. 2 is a. vertical central cross-section; Fig. 3 shows a draft plate in elevation; Fig. 4: is a front view; and Figs. 5 and 6' are transverse sections, one on each side of the central longitudinal vertical plane. taken on the lines 5 and 6 respectively of Fig. 1.

Having reference to the drawings b means of characters applied to the different parts; the under frame is shown fragmen tarily as consisting of center sills 1, running longitudinally of thecar on each side of the center about a foot apart, a front cross-silt 2 and a bolster 3 beneath the sills secured thereto and extending from side to side of the car,

While the construction which is the subject of the invention-may be used in connection with any preferred form of draft gear, in the present instance, it is shown as applied to a three-key link draft gear of the Farlow type, having three cross-keys, 4, 5 and 6, the front onebeing seated in a slot 7 in the drawbar 8 and normally occupying the centersof slots 9 in the cheek plates and extending through slots 10 in the forward ends of the links. The second key .carries the front follower 11 and passes through the middle slots 12 in the links and 18 in the cheek plates. The rear key carries the rear follower 14 and passes through the rear slots 15 in the links and 1.6 in the cheek plates. Between the followers is the usual spring or other shock-absorbing means 17.

The draft plates 19 which are of a width exceeding the width of the sills to a considerable extent, are secured to and overlie the inner faces of the sills at the front and rear ends so that the lower portions of the draft plates extend well below the sills.

The cheek plates 18 are secured to the depending portions of the draft plates beneath the sills, the draft plates in theform of the invention shown, being slotted at 20 to admit the flanged portions 21 which surround the slotted openings. in the cheek plates. Above and below the slotted openings are stiffening members 24: and 25, see

particularly Figs. 5 and '6. These are in the form of angle irons and'extend in a horizontal direction and are preferably interposed between the cheek plates 18 and the draft plates 19, the upper angle iron 24: having a flange-24! secured to the bottom of the sill. As shown, the member 24 is the longer, and abuts at its rearend against the bolster 3. The draft plates and incidentally the angle irons, 24 and 25 are tied together by means of. a tie-plate 26 shownas provided with end flanges, the latter each having two bolts, which pass through the lower portion of the draft plates and the lower angle irons.

At the forward end, the draft plates have secured to theman angle plate 27 which bears against the end sill 2 and the depending portions of the draft plates terminate as shown, with a vertical shoulder 28 just forward of and in contact with the front The upper stifiening edge of the bolster.

bars or angle irons 24, also terminate at this point, but the upperportion of the draft plate extends well to the rear, over the top of the bolster, being secured to the sill throughout theirlength, and the draft-plate is reinforced at this point by means of a cover'plate 29 which affords a seating surface for the heads of the bolts which pass through the wooden sills, stiifens thedraft. plate and resists the downward bending movement in buffing. Thus the draft plates which carry the cheek plates are rigidly'secured at the front and rear so that they have a thrust against the front sill in drawing and against the bolster. in bufling. They are further'stiffened at. the points of greatest stress by means of the angle irons; 24 and Q5 and the upper'anglcs abut-at their rear y, ends against the bolster so that the buffing stresses, which are the heaviest stresses to -mitted directly to thebolster by way of,

which the draft gear is subjected, are transrigid members amply sufiicient to receive and 'resist them, and the tendency which formerly existed to bend the forward ends of the sills down and break them in buffing v is completely overcome.

The drawing stresses, which are less in magnitude, are fully taken care of by the against the igiaaaw direct thrust against the crosssills as well as the rigid attachment of the whole top portion of the plate directly to the inner face of the Wooden sill.

I have thus described my invention spe-' ciiically and in detail so that its nature and the manner of using it may be; fully understood by those skilled in the art. However,

the specific terms herein are-used in their descriptive rather than in their limiting sense and the scope of'the invention is dcfined in the claims 1 I cla1m 1. A. center construction comprising cendepending draft plates secured to the inner faces of the sills, parallel angle irons secured to theouter faces ofthe plates beneath the sills, having one flange horizontal, the

horizontal flange of the upper angle iron being secured to the bottom of the sill, cheek plates overlying the vertical flanges of the angle irons. and fastened to both the angle irons and: the draft plates.

3.

bottom edges respectively of'tlie depending portion of each draft plate, the upper angle irons having horizontal flanges secured to the bottoms of the draft sills.

4. A center construction consisting of wooden centersills, an end sill and a bolster,

6. A center construction Wooden center sills, an end sill and a bolster, draft plates secured to ,the inner faces of the center sills and extending below. the sills, the rear portions of the plates abutting against the bolster and the front ends against the end sill, cheek plates secured to consisting of the draft plates beneath the sills, reinforcing members in. the form of parallel angle irons having vertical flanges extending between the cheek plates and the draft plates and secured to both, the upper members having horizontal flanges secured to the bottoms of the draft sills and abutting at their rear ends against the bol er, the cheek plates being slotted between t e reinforcing members and having flanges at the edges of the sills extending through the draft plates which are correspondingly slotted.
