j To all who-m it may concern:

Be it known that 1, WILLIAM A; HAY- milion and State of Indiana, have invented certain new and useful Improvements in Car-Couplings,

. of'which the following i a p cification. a j

of car couplers, and morevparticularly to couplers for use with. small rolling stock such as mine cars, lorries and the like.

One object of my invention is the provlsion ofa coupler which is strong and durable,

not liable to he accidentally released, and. quicklyand safely cou'- pled orluncoupledb an operator. 1 j

Another object 0 the invention is to pro vide a coupler which comprisesbut twounits,

thereby providing a single and inexpensive device, with no'loose parts to become lost.

Inthe accompanying drawings the nu f 9 which is provided with the end of thelink 4 of face thereof, the bottorn'of thispockethav These and other objects and. advantages of my invention willbe brought out hereinafter and illustrated in the drawings forming part ofthis specification, and in which-- *igure 1 is a top plan of one ofthe units of my improved coupler.

. M a a bottom 11 which inclines downwardly at one This invention relates to the construction end (see Fig. 5).

pair'of prongs: or

fingers

12 and 13, one on .each side of the slot 8, project forwardly for an appreciable distance, beyond the bottom 11 of this slot. The adjacent vertical faces of the slot 8 are parallel with the ends of the body 2.

The other unit of the coupler comprises a elongated body or'shank 15, the shank having an enlarged rear end 16,. which is provided with'an eye 16 that receives' the link 16 of the chain used to se cure the link to a car. This link also is provided on its upper edge with a grip or handhold 17 that overhangs the forward end of the link (see Fig. 4;). j j The shank or body 15- is also provided lntermediate its ends with a pair of cylindrical bearing pins or projections 18, one on each side thereof, which are adaptedto support the fingers or prongs 12 and 13 of the recessed unit 2 when "the two units .or members" are assembled in interlocking engage- IIlIlt. y j

-Asecond pair of cylindrical pins or projections 19 are integrally formed with, and adjacent .the forward lower edgeof the shank 15, the corner 20 of the shank being rounde'd'ofi tocorrespond with the curvature of the projections. 19. The projections 19 are adapted to fit into the recess or cavity 5 and to engage in the curve oftheunde'rcut wall 7 thereof. j

j A projecting flange 22 extends outwardly from each side of the shank .15 and extends forwardly beyond the end of the shank 15 to the front end of the overhanging grip or hand-hold l7. Theprojections-22 are of sufficient width to. extend beyondthe ends until out of the cavity orpocket 5. When the pins 19-19 are clear of the cavity or pocket 5, the forked link will be disengaged from the opposite link and will'drop, and the other link is then allowed to fall.

In connecting the links to couple two cars the links are lifted until-in practically vertical "lengthwise position. The shank 15 is then slipped into th'e'slot 8 of the forked link 2 and. the

fingers

12 and 13 brought into engagement with the pins 18. The two links are then lowered until the pins 19 rest-in the cavity 5v of the forked link 2 and the wings or flanges 22 engage the upper faces of the link 2. vThe coupler will; then again be in the interlocked position shown in Fig. 5.

" The above. described operations will be repeated from time to time in and coupling the links.

'The advantages of my invention which will be appreciated'by those skilled in the art arise from the compact construction and absence of swinging and removable parts.

Various modifications, as will suggest themselves to those skilled in the art, may be made in the construction of my improved coupler without departing from the spirit of the invention as defined in the appointed claims.

I claim I 1. A car coupler comprising in combination separable links arranged to 'coact in interlocking engagement one with the other and having means for attachment thereof to uncoupling the cars, one link having a cavity therein and having fingers onone end thereof, and the other link having projecting pins 'on opposite sides thereof, arranged to enter said cavity and other projecting pins arranged to engage the under surfaceof said fingers insecuring the links in interlocking engagement.

2*. A car coupler comprising in combination separable links arranged to coaot one w th the other, means whereby said l nks are flexibly connected to the cars, one link having a recess forming an undercut in its upper 'face and having projecting fingers forming a slot on one end thereof, and the other link having pr'ojecting pins on opposite sides thereof adapted to enter said undercut cavity and other projecting pins arranged for engagement with said fingers in connecting the links ineinterloc-king engagement, and one end of said second link extending'into the slot formed by the fingers on the recessed link.

3. car coupler comprlsing a forked link and coacting link, said forked link havinga cavity in the upper face thereof and being slotted longitudinally, said coacting link having cylindrical projections on the sides thereof adjacent its forward end adapted to enter said cavity in said forked link, and means for supporting the forward end of said coacting link on said forked link.

4. A car coupler comprising in combination separable links arranged to coact in interlocking engagement one with the other and having means for attachment thereof to the cars, one link having a cavity therein and having fingers on one end thereof and the other link having projecting pins on oppositesidesthereof, some of said pins being arranged to enter said cavity and other of said pins being arranged to engage the under surface of said fingers in securing the links in interlocking engagement, and means on one end of one link forming a handhold for manipulating said links.

5. A car coupler comprising in combination separable links arranged to coact in sides of the second link forming flanges engaging the upper surface of said forked link in connecting the links in coupled relation.

6. A car coupler comprising in combination separable links arranged to coact in interlocking engagement one with the other and having means for attachment thereof to the cars one link having a cavity therein and having fingers on one end thereof and the other link having projecting pins on opposite sides thereof, some of said pins being arranged to enter said cavity and other of said pins being arranged to engage the under surface of said fingers in securing the links in interlocking engagement, and means on one end of one link forming a handhold for manipulating said links and lugs on the sides of the second link forming flanges engaging the upper surface of said forked link in connecting the links in coupled relation, and. an extension on the flanged end of said other link forming a handheld for manipulating said links.

7 A car coupler comprising, in combination a forked coupler link and a coacting link, said links being adapted to be interlocked, said forked link comprising a body portion terminating at its forward end in a pair of fingers and having a cavity in its (upper face provided with a concave wall,

. support the fingers of said forked link, cy-

lindrical projections on each side of said seciond link at'the forward end thereof, eXtending outwards therefrom, said projections being adapted to fit into-the cavity in said forked link, flanges forming shoulders on said second link adapted to overlie the cavity in said forked link and engage the body thereof, and a hand-hold on said second link. r a

8. A car coupler comprising a forked link and a coacting link adapted to be interlocked, said forked link having a cavity in the upper face thereof, said eoaoting link having a pair of projections on the-sides 20 thereof adapted to enter andinterlook with the cavity in said forked link, and meansfor preventing said links breaking downwardly beyond a horizontal plane when interlocked.
