Application led January 29, 1910. Serial No. 540,733.

To all whom 'it mag/concern.:

a citizen Aof the United States, residing atl Alliance, in the county of Stark and State of Ohio, have invented certain-new and useful Improvements in Car-Couplers, of which. the followin is a specification.

My invention relates to that class'of coupe which employs a pivoted knuckle, a'lock therefor, and a lifter for operating the lock. This general ..type 4of` lock is disclosed in the patent granted to J anney, Kinne, and Trump, on

`November 24, 1908, No. 905,078. The construction therein disclosed 'embodies a lifter which projects out through `the top of the coupler head or casing, and is adapted to be operated by means disposed above the couplerliead. l

-Itis an object of my `present invention to provide a construction in which the lock lifteifshall be entirely inclosed within the casing, thereby obviating the danger of the lifter being broken off or 4displaced when it i's-in its elevated position. further object is the provision of means fori' actuating the lifter, which is adapted to besec'ured upon the coupler head and to project "beneath the lifter, whereby the lifter is operated from below. Furthermore, 'the operating mechanism is so constructed that it constitutes a two-way lifting mechanism which may be operated by pulling a chain or rod from either side of the car, ,thereby eliminating the usual handles, rock-shafts and levers, which are ordinarilyattached to the sill-beam of the car. In the patent above referred to, the lock is prgvid'ed with anti-creeping provisions which are normally in operative position .'when the lock is in locking position. In

my present invention I have provided the lock Awith anti-creeping provisions., lwhich `are normally in inoperative position, but

which are brought into operative position toprevent creeping of the lock, as soon as the lock begins to creep. The shoulder on the interior of' a coupler shank, and the hook on thelock, which-constitutes the anticreepingprovision, being normally out of.

engagement with each other, aiford no-frictional resistance to 4the raising of the rear end of the lock in the initial opening movement thereof. Creepingv of the lock, however, is eiectually prevented because as soon as the forward or locking end of the lock begins to creep under draft, the anticreepmg provisions are brought into operative relation and further creeping movement is prevented. ,f

which -In Lthe accompanying drawings illustrate a preferred embodimentl of my invention Figure 1 is a plan of my improvedc0upler. Fig. 2 is an elevation thereof. Fig. 3 is a section on the line 3 3 of Fig-1. Fig. is a perspective of th'e side lifting mechanism.

In the drawings, 6 represents-the coupler head or casing; 7 the knuckle; 8 the lock, and 9 the lifter. `These parts are so constructed and arranged that the knuckle is adapted t be held in closed position by the lock,-and said lock isreleased from locking position by vertical movement of the lifter. The lifter is disposed entirely Within the casing and is adapted to be guided in its vertical movement by a rib 10, which extends outwardly and downwardly from the casing wall. l This rib engages withl a groove- 9 in the side of thelifter 9, and said litter is provided with a shoulder 11 for engagement `with .the `underside of the lock 8, to lift the lock into unlocking position.

In orderfthatpthe lifter may be disposed entirely. wi thin the casing with no portion thereof proecting outside the casing, I have 2. The draw head 6 is constructedr to provide a depressed portion 14, adapted to receive and guide'the lower endV of the lifter 9, and open at one side as at 15, for the reception of the laterally and the downwardly extending bearing portion 16 of the lifter actuating device. The lifter 9 lrests upon and is supported by this bearing portion rof the lifter actuating device, which normally assumes the-position shown in Fig. 3, with the lifter in lowered position and the lock in locking` position and the lower face of the bearing portionliiL resting lon the lower wall of the portion 14 of the casing.

It Will be noted that I make the bea-ring portion 1G of comparatively large size. This mass of metal in addition to providing a large bearing surfacefor the lifter, acts as a counterweight and avoids the necessity for springs or other means to return 'the opener to normal position.

In order that the lock may be actuated from either side of the car, I have provided the lifter actuating mechanism with an upwardly extending arm 17 and la downwardly extending arm 18, to the ends of which are attached rods 19 and 2O or other operating means. It Will be evident that by pulling upon'either one of .these rods from either side of the car, the lifter actuating device Will be rocked on its pivot to raise its bearing portion, thereby raising the lifter and bringing the lock into unlocking position to -release'the knuckle; The lock is supported on the tail of the knuckle when the latter opened, While the lifter and the lifter actuating mechanism are allowed to resume their' normal position.

The lock shown in the drawings is supported at its rear end Within the shank ot' the coupler, its foi-Ward end being l'leavy and provided with a :tlat face to make con,- tact with the vertical. face ot' the knuckle tail, and being supported when in its lou'ei` most position, by a ledge Qliin one side oi?" the .draw head, as shown in Fig. 3.

My invention affords a coupler in which thelock is easily actuated because the ini` tial movement of the lifter is opposed only` by the Weightof the front end f the lock, the anti-creeping provision being in inoperative position, thereby affording no frictional resistance to the upward movemient yof the lifter, and thc arms 17 and 18 of the lifter 4 actuating mechanism being longer t-han the bearing portion 16, an effective leverage is afforded, which multiplies the power applied to the rods, and renders the manipulation of the lock easy and certain. lWhile I have shown and described the preferred embodiment of 'my invention, it will be evident that various minor changes inthe construction and mechanical details may be resorted to without departing from the spirit of the invention as set forth in i the appended claims.

llfhat I claim is.'

l. In a car coupler, the combination of a coupler head having a pivoted knuckle, a lock, and a lifter disposed internally of vsaid head, a lifter actuating lever pivoted to said head, said lever having a Weighted portion which is normallydisposed Within a recess iu said head, and means for actuating said lever, substantially as described.

2. In a carroupler,-the combination of a ,draw head having a depressed portion provided with an opening 1n the side thereof,

a knuckle pivoted in said head, a lock for said knuckle, a lift er for the lock, and means for operating the lifter pivoted tothe side of the draw head 'and comprising a bearing portion projecting into the draw' head through the opening in the side of the depressed portion thereof and a plurality ot" lever arms extending in opposite directions from the point of pivotal attachment to the draw head, whereby to actuate said lifter v and lock, substantially as described.
