I Application filed February 13, 19 22. Seriallil'oQ536,237.

To all whom it'may concern: Be it known that I, FRANK P. :FLINN, a citizen of. the United States, residing at .Terre Haute, in the county connected on contact unless the coupling link is projected fromits drawhead, so: that a loadedcar may be made to bump an empty car ofl' a cage.with0ut coupling. Another object is the-provision of an automatic coupling eflicient' on short curves and adapted to transverse curves without liability ofthe drawheads locking.

To the attainment of the foregoing, the

invention consists in the improvement as hereinafter described and'definitely claimed.

In the accompanying drawings, forming;

part of this specification Figure 1 is a plan view of my improvement. 1

Figure 2 is a side elevationof the" same.

Figure 3- is a horizontal section taken in the plane indicated by the line 3-3 of Figure 2. 1

Figure 4 is a longitudinal section on line.

4-4 of Figure 1.

Figure 5 is a similar view which shows the opposed drawheads as connected to getlier.

Figure 6 is a perspective of the coupling link per se.

Figure 7 is an enlarged detail perspective of the slidable body of one drawhead.

Figure 8 is an enlarged perspective of the pin of said drawhead.

Figure 9 is an enlarged perspective of the lever carried thereby.

Similar numerals of reference designate corresponding parts in all of the views of the drawings. Y

The opposed ends of two cars l and 2 shown in Figures 1-5.

Carried by the illustrated end of the car 1 is a housing 3 in which is fixed a guide are of Vigo. and State of Indiana, have invented new anduseful Improvements .in Automatic Car. Couplings, of which the following is a .speciblock 4: and inthe outer end wall .of which i is a guide aperture 5.

The block 4 includes. a transverse-central apertur'ed wall 6 and sleeves 7 at opposite sidesof the same. v V o Movable longitudinally through the wall 6 and sleeves 7 is a drawbar8 on which is a'nut or other appropriate abutment' 9- .between which andthe wall 6 is a coiled spring 10,'mou'nted on the bar8g The outer end ofthe drawbar 8 extends into-the hollow shank 11 of a drawhead 12, and is con- V nected to said shank 11 through the medium of a pin '13. Disposed in the drawhead 12 is a slidable, spring-locked body 14 in;

whichis a longitudinal slot'15 to receive a limiting pin 16*, carried by the drawhead.

The mouth of the drawhead 12 is flaredas shown, and in the upper and lower walls mouth, are vertically-alined apertures '16 ot' the drawhead at points adjacent to saidand 17 for the reception of a heavy and strong pin 18, preferably circular in cross section and provided with a reduced and 19.. On the upper side of the drawhead '12 are-parallel standards 20 between which is flattenedandapertured upper end portion fulcrumed a lever 21, the outer end of}, which is bifurcated at 22 to straddle the pin portion 19, and is provided in the walls ofI- the bifurcation with longitudinal slots 23 to receive the pin 24 by which'the, lever 21 is connected to the pin 18. The pin 18 and the lever 21 are'yieldingly maintained in and adapted to be placed in thepositions'shown 9o,

i1rFigure5- by a strong spring 25- which bears against the upper side of the draw,-

head 12 and theouter-arm Figures 2, 4 and 5, lever 21 is connected through a link 26 with of the lever 21,

a crank 27 on a transverse shaft 28, journaled in appropriate bearings 29 on the end of the car body 1 and having cranks 30:11: its ends, Figure l. Manifestly when it is desired toraise the pin 18 to enable the body 1 1 toassume a position under said pin 18, Figure 4, the same may be conveniently accomplished by an aperture standing at I either side of the car or car body 1. V The drawheadv 31 carried by the car or car body 2 and designed to cooperate inop posed relation with the drawhead 12, is housed in and held against longitudinal movement relative to said car body 2, is provided with a chamber 32, and is also pro- The inner arm of the thereof from the position shown in Figures 3 and 4 to that shown in Figure 5 and vice versa. On theinner end of said link 35 is an a Jertured ton ue 36 and ainned or othera a l wise connected to said tongue 36 is the slotted head 37 Figure 3, of a bar 38, the slot in the said head being ofarcuate form and receiving the pin 39 so as to permit the link 35 to swing horizontally relative to the bar 38. The said bar 38 is guided ii'or rectilinear, longitudinal movement in the shank 33 and is longitudinally slotted at 40 to receive an upstanding crank 41.0n a transverse shaft 42, jonrnaled in appropriate bearings on the car body 2 and having handles 44 at its ends and at opposite sides oitthe said body 2. From this it follows that an operative at one side of the body 2 is enabled with out goingbetween the cars, to project the link 35--1. e., move the same from the position shown in Figures 3 and 4 to that shown in Figure'5, and this against the action of the retractile spring 45 which is interposed between and connected to the crank 41 and the car body 2. Obviously the projection of the link 35 tensions the spring 45, with the. result that immediately following the release 03": the said link 35 from the pin 18 of drawhead 12, the said spring 45 will promptly draw the link 35 into its fully-housed position in the drawhead 31 and inwardly beyond the abutting end or face of the said drawhead 31, Figures 3 and 4.

It will be apparent from the foregoing that while the drawhead 31 has no movement relative to the car body 2, the drawhead 12 is movable longitudinally with respect to its car body 1 and is cushioned in its opposite movements by the springs 10, Figure 3. It

will also be apparent thatjto couple the cars it is simply necessary for an operative to project the link 35 precedent to the coming together of the drawheads,when the link 35 will engage and move inwardly the body 14,

the coupling, and this in such manner that casual uncoupling will be precluded.

It will further be noted that in virtue of my improvement it is entirely practical to couple and uncouple cars though they be standing with the drawheads 12 and 31 in:

equipped with a coupling'link, and means extending to the side of thecarbody, wherewhereupon the spring-:lt'ctuated lever 21 will force the pin 18 into the link 35 and complete by the link may be manually projected from v the draw head, this means including a rectilinearly movable-bar and an areuate coupling between the outerend of said bar and" the inner end of the link wherebythe inner end of the link is adapted to move horizontally relative to the outer endof the bar.

In a car coupling,-a draw head being equipped witha coupling link and means extendingto the side of thecar body, whereby the link may be manually projected from the draw head, this means including rectibetween the outer end ofsaid bar and the inner end of the link, whereby the inner end of the link is adapted to move horizontally relative to the outer end of the bar and also handle means, and also-having a crankengaging thebar, and a retractile spring interposed between and connectingjthe crank and the car body and tending to retract the link.
