CREEK PLATE.

To all whom t may concer/n.:

Be it known that we,.BYERs W. KABEL -and PERCY R. DRENNING, citizens of the United States, residing at Baltimore, in the State ignated as the Farlow'two-key draft gear attachments.

This invention has for an object the provision of a strong, durable and easily applied cheek plate capable of effectively fulfilling the requirements of operating conditions, said cheek plate' being formed with a plurality of key-receivin slots adapted to extend through a body we portion, said web portion being gradually tapered from each end of the cheek plate toward the center to provide graduated cross sectional areas throughout the length of the cheek plate.

Another object of the invention consists in forming a cheek late with a body web having a relatively at inner face arranged to engage the outer face of the center sill, and an inclined outer face adapted to form with said inner face a varying cross sectional area throughout the length of the cheek plate, said cross sectional area being relatively large at the central or intermediate portion of the cheek plate and adapted to diminish in net cross sectional area t0- ward each end thereof.

A. further object of the invention is to provide a cheek late formed with a plurality of reinforced ey-receiving slots, one of said slots having an inwardly projecting fiange passing thrQu h the respective slot in the draft sills, and having a portion projecting inwardly thereof in close proximity to the yoke, and an outwardly projecting flange aving an enlarged portion at one end adapted to form with said inward'lyprojecting ortion a relatively'lar e bearin area for t e ke connecting. the yo e and fo lower block of tlie cushioningmechanism.

The invention further consists in the comlbiiiation, arrangement and construction of the several parts hereinafter described and pointed out in the claims.

ln the drawings illustrating our invention Figure 1 is a horizontal sectional view of a pair of cheek plates embodying the invention, showing the relation to the center sills of a car and to the form of draft gear attachments with which they are especially suited.

Figure 2 is a view in side elevation of a p ortion of the outer face" of one of the -car sills, showing the cheek plate attached thereto. i

Figure 3 is a horizontal sectional view through the cheek plate.

The type of Farlow two-key draft gear mechanism illustrated in the drawings, includes the carcoupler 1 which is operatively connected to the draft yoke 2 by a transverse coupler key 3 which latter extends through a slot 4 in the shank of the coupler, thence through the elongated slots 5 provided at the forward ends of the yoke arms, and then through the key receiving slots of our improved cheek plate 6 connected to the center or draft sills 7 of the car underframe. Associated with the coupler and at the rear of the shank thereof, is arranged the follower block 8 having the key 10, said key being 'adapted to pass through elongated slots 11 provided in the arms of the yoke, and projecting into anotheil series of key-receiving slots formed in the cheek plates 6 fitted to the draft sills;

lt will be understood by those skilled in the art that the car coupler 1, upon performing a buiiing operation, causes the follower block 8 and the two keys 3 and 10, respectively, to travel rearwardly into corresponding slots of the cheek plates and of the draft yoke, the latter being prevented from retreating by means of a suitable hackstop or by abutments (not shown), rigidly connected to the cai'. When, however, the coupler l is pulled outwardly the key 3 draws the yoke 2 along with it while the rear key 10, by bearing against the cheek plates at the forward. ends of their slots, arrests the follower bloc'k 8 and transfers the pressure to which the latter is subjected to the cheek plates and thence to the center sills or draft sills. While my present form of cheek plates is particularly adapted for use in conjunction with the particular type of draft a slot 9 adapted to receive tev EGG

Miti

, whereby 1t may be rigidlphattached to sind sill by rivet means 13. e outer face'of the bod web of each cheek plate is gradually inclined or tapered from each end of the cheek plate to an intermediate portion to provide a maximum cross sectional area at or about a oint adjacent the opposite inner ends of t e key-receiving slots, as indicated by the numeral 14,the cross sectional ras ` the endsthereof.

area of the material being gradually diminished toward each end of the cheek plate to the normal cross sectional area of usual bod web construction. In side elevation it wi l also be noted that the top and bottom edges of the cheek vplate are reversely inclined or tapered from an intermediate point toward With the exce tion of the outermom rivets at each end o the cheek plate, the latinajority of the rivets 13 are maintain in horizontal alinement throughout the length of the cheek plate. Bosses vare preferably provided on the outer face of the cheek plate, said bosses surrounding the rivet openmgs and being located at the re- 'i tive points from the upper and lower v of the cheek plates, as shown.

` i l e bosses provide for the proper insertion of the rivets through the cheek lates without ar displacement thereo due to the graduated cross sectional area of said cheek plates.

Key-receiving horizontally

alined slots

15 and 15 are provided in the cheek plates, the slots 14 being adapted to receivev the roe jecting ends of the coupler key 3 and the ots 15y be arrad to receive the extending ends oligthe key connecting the follower block and yoke. Projecting mwardly from the y web of the cheek plate and surrounding the key slot is an inwardly extending flange 16 adapted to lit within and c i the edges of a slot 17 formed in the forward end of the center sill. The inwardly extending dan 16 is preferably adapted to terminate ush with the inner face of the center sill, as shown. An out wardly projecting flange 18 extends from the outer face of the body web of the cheek plate and, together with the inwardly extending ilange 16, serves to form the slot 15. The respective ends of the slot 15 form stop portions for the respective forward and rear edges of the coupler key 3, as will be understood The key-receiving slot 15 in each cheek plate is provided with an inwardly extendn insane `ing flange 19, said lian e being inclined forwardly, as shown, an adapted to extend inwardly of the draft sills into relative close proximity to the side arms of the yoke. An outwardl projectin flange 20 surrounds the key s oty 15', said an 20, together with the inwardly extending an e 19, forming a relatively large Vand strong ey support and bearing for effectively receiving and transferring the strains to the draft sills. The forward portion of the outer flange 20 is enlarged and reinforced, a fillet 21 being provided for permitting clearance for the cotter in the use of a standard length key.

Diagonally arran ed webs 22 serve to re inforce the forwar portion of the outer flange 2O and the inner rtion of the outer flange 18, a. longitudine y arranged web 23 connecting said flanges at their respective inner ends, a's shown. The outer flange 20 is reinforced at its op osite or rear end by means of diagonal we s 24, and a longitudinally disposed web 25 as shown. A longitudinally arranged web 26 is provided to reinforce the forward end portion of the flange 18. The reinforcing webs arel advantageously positioned to brace the llangesreceiving the buiiing strains and imparting them to the car underframe. The outer flanges surrounding the

respective key slots

15 and 15 are relatively thickened at each end, the reinforcing Webs integrally uniting the body web portion of the cheek plate to the flanges, thereby providing for a strong constructionV with an 'advant ous distributionl of the metal in obtaining maximum strength value with a minimum of material employled.

c eek plate constructed in accordance with our resent invention provides greatly increased ey bearing area, said area being e'ectivel ally rein orced by the intermediate increased cross sectional area of the body web of the cheek plate.

We claim: Y
