CHEER PLATE. I

Application filed January 23, 1922. Serial No. 531,223.

To all whom it may concern:

Be it known that I, ARTHUR H. WEs'roN,

, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Cheek Plates; 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 invention relates to the construction of cheek-plates of the type employed in the well known form of draft rigging mechanism commonly designated as the Farlow two-key draft gear attachments. The primary object of the invention is to produce a cheek-plate of the type referred to which will efliciently fulfil the requirements of operating conditions and be capable of application to the car underframe with a mlnlmum expenditure of labor for fitting.

The principal feature of the invention, generally stated, consists in forming the cheek-plate with a body web affording means for riveting or suitably securing it to the center sill or draft sill of a car and in providing it with a plurality of keyrecelving slots which are adapted to register with a continuous slot formed in the car sill to which the cheek-plate is applied, the cheek-plate also'being furnished between its slots with a portion adapted to project through the slot in the car sill.

A further feature of the invention consists in providing a cheek-plate with a body Web affording means for securing it to the center sill or draft sill of a car having a continuous slot therein, and in providing a plurality of key-receiving slots adapted to register with said continuous slot, the structure also being formed on oneside ofits web with flanges which respectively border its slots and project from said web to a greater extent at the adjacent ends of the slots in the cheek-plate than at the remote ends of said slots. p

As will hereinafter appear, there are other features of the invention residing inparticular details of construction.

In the drawings illustrating the inven-' tion, the scope whereof is pointed out in the claims Figure l is a horizontal sectional new I, of a pair of cheek-plates embodying the invention, showing their relation'to the center sills of a car and to the form of draft gear attachments with which they are especially suited to be employed.

Figure 2 is an elevational view of a portion of the inner side of one of the car sills, showing the cheek-plate attached thereto.

Figure 3 is a horizontal sectional view of the cheek-plate.

In the well known Farlow two-key draft gear mechanism illustrated in the drawing, the car coupler 1 is operatively connected to the draft yoke 2 by a transverse key 3 which extends through a slot 4 in the shank of the coupler, through elongated slots 5 at the forward ends of the arms of the yoke,

through the center sills or draft sills 6 of the car underframe, and through suitable elongated slots 7 with which the cheek-plates applied to the said sills are provided toward their forward ends. At the rear end of the coupler shank is a slotted follower block 8 receiving a key 9 which passes through elongated slots 10 in the arms of the draft yoke 2, through the car sills 6, and through suitably elongated slots 11 with which the cheek-plates are \furnished. As is understood by those skilled in the art, the car coupler 1 of this type of mechanism upon performing a buffing operation causes the follower block 8 and the two keys 3 and 9, respectively, to travel rearwardly in the corresponding slots of the cheek-plate and of the draft yoke 2, the latter being prevented from retreating by means of a suitable back stop or by abutments (not shown) rigidly secured to the car. When, however, the coupler 1 is pulled outwardly the key 3 draws the yoke 2 along with it, while the rear key 9 by bearing against the cheekplates at the forward ends of their slots 11 arrests the follower block 8 and transfers the pressure to which the latter is subjected to the cheek-plates and thence to the center tomary, each of the sills 6 is provided with a single continuous slot 12 which is of somewhat greater length than the distance separating the forward end of the cheek-plate slot 7 from the rear end of the cheek-plate slot v11'. I

Each cheek-plate 13 is formed with a body-web 14 which is adapted to contact the outer side of the web of the adjacent sill 6 and is' provided with suitable. openings whereby .it maybe rigidly secured to the neighboring sill-by suitable means, such, for.

example, as the rivets '15. The cheek-plate 13 is formed with twoindependent horizontally alined slots, 7 and 11, respectively, the former being for the reception of the key 3 and the latter; for the key 9. Projecting inwardly from the web 14 and borderingthe slot 7 is a flange 16;'and the slot 11 of the cheek-plate is similarly bordered by an inwardlyprojecting flange 17. These bordering flanges 16 and 17 are adapted to project through the continuous slot 12 formed inthe neighboring car sill 6.

The parts of the flanges 16 and 17 which are at the adjacent ends ofvtheir'respective slots 7 and, 11 are integrally united andbraced by a portion of the cheek-plate which also extends into the slot 12 of the carsill,

the said uniting portion preferably comprising a plurality. of spaced webs 18 integral y united to the body web 14 and respectively fonming connecting prolongations of the portions of the flanges 16 and 17 bordering the upper and lower margins of the slots in the cheek-plate.

For a portion of its length the flange 16 preferably slopes, as at 19, toward the body web 14 from the neighborhood of the inner end of the slot 7 toward the outerend of said slot. Adjacent the inneriend of the cheek-plate the flange 17 forms a key-bearing portion 20,- to the rear of which and spaced therefrom is a sill engaging flange 21 preferably united to said key bearing portion by inclined tapering webs 22. This not only efliciently braces the portion of the cheek-plate which is between the slots 7 and 11' against such strains as may be communicated to the cheek-plate by the keys 3 and 9, but it effects an advantageous distribution of-metal decreasing the'weight of the device, and reducing the diflicultiesof perfect casting and also effectually transmits to the sills the bufling shocks delivered thereto by the key 9'. ,Moreover, the bordering flange 16 whe1i thus formed aflt'ords ample clearance for the draft yoke 2 and the inward projection of the flange prevents all wear upon the sill due to the movement of the yoke in service.

The slots 7 and 11 are preferably also box: I

dered on the outer side of the cheek-plate 13-with flanges 23 and 24, respectively, the

adjacent portions of which are preferably 1ntegrally united to-eachother and to the body web 14 by webs 25 corresponding to g the webs 18 connecting the bordering flanges 16 l:tnd 17 on the opposite side of the body we By extending the key bearing portions of the cheek-plateinwardly of the sill faces I greatly increase the bearing area for the keys and reduce the-unsupported portions of the keys to such extent that the keys are practically indirect shear under loads.

In applying the cheek-plates 13 to the car sill. 6 it is only necessary to do the work required to permit the forward end of the in ,ner bordering flange 16 and the rear end of i the inner flange 21 to fit properly within the correspondingtcar sill slot and then to drive the rivets 15.

I claim A j 1. A cheek-plate having a body web affordin means for securin it to a center sill or draft sill of a car, an having a key receiving slot adapted to register with a slot in the web of said sill, and being provided on opposite sides of said web with flanges bordering said slot, one of said flanges being adapted to project through and beyond the web of said' sill to form a guiding sur said cheek plate, and means projecting from v the'web of said cheek-plate between said flanges, and additional means also 'connected to the web of said cheek-plate and projecting therefrom and interposed between the-rear of said sill slot and the marginal flange of said cheek-plate'slot for reinforcing said cheek-plate.

In testimony whereof I afiix my signatu-re.

ARTHUR H. WESTON.
