' To all whom it -naz/ z/ concern:

operated car couplers.

One object orn the invention is to provide an automatic ear coupler which may be operated without requiring the brakeman to pass between the cars, and which is simple in construction and etli'cient in operation.

Another object 'of the invention is to provide an automatic coupler which will be sleet and ice proof.

Another object is to provide a coupler ot this class which may be easily coupled without excessive jamming when the cars are on a curve.

With these and other objects in view the invention consists ot' certain novel features of construction, combination and arrange- 'ment ofparts as will he more` fully described and particularly pointed out in the appended claims.

In the accompanying' drawings, Figure l represents a top plan view of a car coupler constructed in accordance with this invention; Fig. 2 is a horizontal sectional view thereof; Fig. 3 is a longitudinal vertical section; Fig'. el is a vertical transverse section taken on the line 4 4 of Fig'. l; Fig. 5 is a perspective view of the. knuckle detached: Fig'. G is a perspective view taken from the end ot' the drawhead with the knuckle removed: Fig. 7 is a similar view of the operatingV member: Fig. S is a perspective view of the locking` device detached; Fig. 9 is a .horizontal sectional view through the drawhead with the knuckle and locking' device removed; Fig. l0 is a vertical sec# tional View taken on the line 10-10 Fig. 9: and Fig. l1 is an end view taken from the front of the drawhead with the knuckle removed and the locking device in operative position therein In theembodiinent illustrated a draivhead,

The butter, 2, may be omitted when the coupler is to be used upon passenger cars, but is used if desirable for freight cars.

The drawhead, l, is madeA hollow and is provided with a pair of opposite arcuate lugs or ribs, 6 and 7, having beveled faces 6 and 7 to form an outwardly liar-ed slot-like opeuinglfor the reception of one end of the knuckle 5, hereinafter described. The'se ribs 6 and 7 terminate at their outer sides in vertically disposed shoulders as 8 which are curved laterally and inwardly and the inner sides of said ribs terminate in vertically disposed shoulders as 8 which are curved-laterally outward and in connection with the shoulders 8 form the rib-.like upper and lower guides 6 and 7 for the knuckle 5, in its lateral swingingmovement.. The rear end-of the knuckle, 5, shown in detail in Fig. 5, is provided on its upper and lower faces with curved recesses, 9, and 10, extending the entire 'width of the knuckle and having arc-shaped shoulders, as 11, forming the outer walls thereof, the bottom l2, and l2 of said recesses 9, and 10, being inclined inwardly in opposite directions and curved laterally to adapt them to fit the i11- clined or beveled faces, 6 and 7 of the drawhead. V ertically disposed shoulders as 13 forni the inner walls of said recesses, 9 and l0, and are curved laterally outward to correspond with the curvature of the shoulders 8 ot' the drawhead with which they are adapted to engage; the outer shoulders l1 of the knuckle engage the inner shoulders 8 of the head, and the

beveled faces

12, and 12 are 'in operative enga ement with the correspondingly beveled aces .6 and 7 of the drawhead lugs 'or ribs 6 and 7. The knuckle, 5, is also provided on its upper and lower faces near its froht end with laterally curved concave shoulders as 5 for coperation with the edges of the curved ends of "the` ears 3, and, 4. The `face ofthe rear 'end "of this knuckle v5 is provided `with a cammember' preferably formed bygmntting out a ort-ion of said face to forni' a diagonally disposed shoulder 14 extendingfrom the lower inner end of said face toits outer upper end, said shoulder being curved slightlyoutward longitudinally toward its u'pper end. Atthelower cuter corner of said rear knuckle face is formed a v,stop ing, 15, projecting 'in a longitudinal direction for a purpose to he l The .rear face *of*` the knuckle is also providedat its'inner end with an an' described,

The lug, 15, on the outward swinging of the kn'uckle comes in con- 5 tact with the lower face of the arm, 29 and the endof the lever, 2l, and holds the knuckle k'against accidental disconnection from the drawhead. This lug,.15, preferably has its inner face curved and when the against causes the knuckle to move inward into operative or locking position.

' In the operationof this device the coupler `beingloc'ked in closed position, to release it,

it is necessary to pullupon a' rod,26, connectecl with the lever, 21', which causes the free end'of 'said lever to ,swing upwardly and raise -the;block, 16, and immediatelythereafter the arm, 22, engages the cam loo member of the knuckle and swings said knuckle into open position, Y thus uncouplngthe cars. -v To couplethe cars, the knuckles being 1n openposition 1t is necessary only to jamv them together when the knuckles will engage with each other-and the blocks, 16, will drop down by gravity and lock said knuckles in operative position. yF rom the foregoing description taken in connection with the accompanying vdrawings, the construction andoperation of the invention will be readily understood ,vithout requiring a more extended explanation.

' Various changes in the form, proportion and the minor details, of construction muy be resorted to without departing from the principle or sacrificing any of the advantages of this invention-as defined in the appended claims. Y

I claim as my invention l 1. 1n a car coupler the combination of a hollow drawhead a knuckle mounted to swing laterall therein, the inner free end of said knuck e being provided with a face 'adapted to lie opposite one'face of said-hole.
