il) all whom r may Concern.'

lle it known that l, Hass P. Pnreae'nx, a subject ot the King' of Denmark. residingr at South Tacoma. in the' county ot Pierce and State ot lll'asnij iron. have invented certain new and useful lmproi'elnents in Draft AppliancesT of which the following' a specification.

rl'his invention relates to improvements in draft appliances for railway cars, and particularly to draft bar Connections.

An object in 'iew is the facilitating of the application of the draw bar tothe 'draft beam connections and the eflicient locking of the parts in their given positions, While providing for the retpiisite reciprocal and lateral plav et the draw bar.-

`With this and further objects in View, as will hereinafter in part become apparent and in part be stated, the intention comprises the combination with draft beams, of -a draw bar adapted to extend therebetween, stops connected to the draft beams and surrounding the draw bar, follower plates carried by and movable along the draw bar between the stops. springs pressing` the plates against the stops, and a detachable locking sleeve retaining; the draw bar against release from the follower plates.

The invention further eoinprehends the etmibination. with draft beams and cross stops. oli a draw bar extending between the draft beams and past the stops. follower giilates carried by the draw bar. spacing springs engaging the follower plates. a shouldered sleeve adapted to retain the draw bar against displacement relative to the fola locking sleeve detachably engaging' the draw bar vtor retaining the first mentioned sleeve in position.

The ingention further comprehends certain` other novel constmietions .combinations and arrangements of parts. as Will be hereinafterdeseribed and claimed.

In the accompanying drawing: Figure l is a longitudinal7 vertical section through draft apparatus embodying the Vfeatures of the present invention. l-=`i is an inverted plan View thereof. Figs. 3., fl, and G are transverse., *vertical sections taken on the planes indie-ated respectirely by lines tl-3, eifel, 5 5 and tlw et Fig: l and looking respeetirely in the directions indicated bj.' the arrows. Fig 7 is an end View of the i,

oeking sleeve detached. Fig. 8 an end rienv or `the draw bar detached. the sleeves being' omitted. Fig. 9 is a longitudinal. rc1'- tical, central sectionthroi -'h a u odilied embodiment of eouplervbar and loc Referring; to the drawinghy indicates the ooring of the superstructure of a car which may be ot' anY tjfpe and provided with the usual sub-structure, not illustrated, and with the usual draft beam. not shown with which latter are connected the draft sills 2.l 2, which ma): be disposed in conventional arrangement relative to the draf-t beam and body bolster, the latter also not. being illustrated. The beams 2 are spaced apart and are connected at various points along their length by cross webs forming` stops 3, .3. The outermost stop is preferably disposed immediately in the rear of the butler block l and consists preterably of

cross plates

5, 5 one haring its ends fixed to the respective sills 2 at their lower 4edges and the other haring its ends fixed to the sills 2 at their upper edges, and each beingY bent intermediate its ends toward the other and' connectedbiY spaced aps or metal strips-6, 6 haring their .ends xed to the cross plates 5,the

plates

5 and 6 thus forming a rectangularly inclosed space through which extends `the draw |bar Y which isI preferably rectangular in cross section tin'oughout that. portion of its length extending through the opening between the plates and 6. Each of the other tivo stops is made up ol upper and lower cross pieces or plates-connected at their ends to the respective upper and lower portion of the beams :2, and the cross pieces S being. in turn connected by connecting plees 9, the latterbeing' arcuate in form and conforming to curved portions of the pieces S, whichv Curved portions, Withtlie'plates or connecting pieces 9, provide a circular closure throughwhich'the dral bar T entends, the draw bar being' cylindrical throughout those portionsv ot its length extendingY through the stops 3, in the rear ot' the outermost stop 3. The cross sectional arca of thc dranv bar reduced just inside the outermost stop forming' an abutting' shoulder l0. and the portion of the dra-iv bar in the rear of the shoulder lt?. beginning "at the shoulder. is cylindrical and of uniform diameter for a length .snllicieut for extending' from the out ermr'st stops 3 to the intermediate stop Il. and there-at the dra'rt ba' i' is formed with 110 an annular Shoulder 11 and extends thence Iarwardly in the form of a' reduced cylinder. l

An annular sleeve 12 surrounds the draw7 bar 7 in the rearl of and extending from rthe shoulder 11 to the rearmost stopl 3, the

-annular shoulder 13 facing forwardlyv at one side of the intermediate stop 3 and the annular shoulder 14 facing rearwardly at the other side thereof.

Adjacent the rear end 'of the draw bar 7 the bar is formed with an annular groove 15 and longitudinal slots 1G, 1G extendingl from the groove'to the end of the draw barA` the slots 1G being of a width sui'hcient for leaving radial lugs or

projections

17, 17, in the preferred .embodiment each lug l17 being 0f a width circumferentially of the draw bar equal approximately to the width of each groove -16 circumferentially of the draw bar.

Mounted on the rear end portion of the .draw bar 7 is a retaining or locking sleeve 18 which has its free end portion of a diameter adapted to loosely fit the opening formed through the rearmost stop 3, such diameter being sufiiciently great for providing a circumferential shoulder 19/at the forward end of the sleeve 18 outstanding radially from the sleeve 12. The sleeve 18 is preferably taperedrearwardly or inwardly as at 20 so as to facilitate reciprocation through the stop 3.` The bore of the sleeve 18 is substantially equivalent in diameter to the diameter of the rearmostI portion of the bar 7 so as to surround the same, and the sleeve is provided with radially inwardly extend ing lugs 2121 corresponding in width ap proximatelyto the dimensions of the lugs 17 and of'a length approximately the same as the width of the groove 15, said lugs being thus adapted to snugly fit the groove and at the same time to be free to revolve thereinj/Tlius in applying the sleeve 18 to the rearv end of the draw bar 7 the sleeve may be projected axiallv onto the draw bar Wit-h the lugs 21 disposed to travel longitudinally of the grooves 16 until the lugs strike against the forward shoulder of the groove 15, wh'ereat the sleeve is adapted to be revolved until the lugs 21 are alined axially with the'lugs 17 and are thereby locked against longitudinal withdrawal from the draw bar. To prevent the sleeve 18 from becoming accidentally revolved to a position of registration between the lugs 21 and the grooves 16 a pin 22 is passed through the tapered portion of the sleeve 18 and through the rear end portion of the draw bar` the sleeve and draw bar 'being formed with apertures adapted to register when the lugs 21l are alined with and forward of the lugs 17. The pin terminates inside the longitudinal planes of the greatest diameter of the sleeve 18 so as to be free to readily reciprocate through the rearniost stopy Innnediately in the rear of the outermost stop 8 a follower block 28 is mounted on the larger cylindrical portion of the draw bar 7 and immediatelyv in front of the intermediate stop 3 is a similar follower block 2t, each` of said blocks being preferably provided with a. sleeve1 extending toward the other along the draw bar for guiding and confining the respective parts. Surrounding the draw bar between the follower blocks 28 and 21 are nested coilsprings 25 and 2G disposed' to have theirends engage the respective follower blocks, the follower block 2l being disposed to engage the shoulder 13 of sleeve 12 and the follower block 28 being disposed to engage the yshoulder 10 of draw bar 7. Surrounding the sleeve 12 are

follower blocks

27 and 28 similar in construction and arrangement to the

blocks

23 and 21, block 27 engaging the shoulder 1-1 of the sleeve 12 and the block 28 engaging the annular portion or shoulder 19 of sleeve 18. Nested coil springs 29 and 30 are disposed between the follower blocks 27 and 28 and have their opposite ends engaging the respective blocks.

As best seen in Figs. 8, 4 and. the stops constitute guideways for the respective parts of the draw 'bar 7, and the openings --formed by the said stops are preferably slightly enlarged laterally, as indicated in the last named figures, for permitting a cerain amountof radial swing of the draw YLT.

In operation, draft stresses are delivered from the knuckle through the bar 7 to the sleeve 18 and thence to sleeve 12 and from the shoulder 19 of sleeve 18 to the follower block 28 and thence through springs| 29 and 30 to follower block 27 and to the interme diate stop 3, While at the same time a draft stress is transmitted also through the sleeve 12 to the shoulder 13 thereof and thereby tothe follower block 24 and thence to ,the

springs

25 and 26 and to the'follower block 23, which delivers the stresses tothe outermost .stop 3, thestops delivering. the draft stresses yto the draft beams 2 and thence to the car structure. lThe buing stresses delivered to the draw bar and the compression stresses also delivered thereto are'transmitted through shoulder 10 to the follower blo-cli 23 and thence through the

springs

25 and 26 to follower block 24 and to the intermediate stop 3, such stresses being at the same time also transmitted from the shoulder 11 to the sleeve 12 and thence through said.

1n Fig. 9 l have illustrated a modified embodiment in which the draw bar 7 is provided with a locking sleeve 1.8, the draft bar and sleeve being similar in construction and arrangement to the draw bar 7 and sleeve 18 but differing therefrom in that a plurality of the locking lugs arranged in longitudinal series is provided. In this embodiment the rear end portion of the draw bar 7 is provided with spaced annular grooves 15 and diametrically oppositely disposed longitudinal grooves 16 connecting the grooves 15 and extending from the rearniost grooves to ,the extreme end of the draw bar, the grooves 1G leaving radially disposed lrciting lugs between the end of the bar and the first,- groove 15 and between each two of the grooves 15. The sleeve' 18 is provided with radially inwardly eX- tending arcuate locking lugs 21 disposed at diametrically opposite points of the bore of the sleeve in position for being adapted to slide longitudinally within the grooves 1'6" and then to be moved circumferentially by a rotary movement of the sleeve 18 to a position axially alined with the lugs of the draw bar, whereby the sleeve '18 is adapted to be locked onto the draw bar. A pin 22 is disposed to extend through a portion of the sleeve and draw bar to prevent any relative rotary movement of the parts tending to allow the locking lugs of the sleeve to move into register with the grooves 16.

Having thus described the invention, what is claimed as new is:

1. ln draft apparatus, the combination of a draw bar having a plurality of shoulders, a draft stress transmitting element engaging one of the shoulders, a sleeve mounted on the draw bar and engaging another of the shoulders, and formed with extension means providing a shoulder, stress transmitting means engaging the last mentioned shoulder, and a sleeve detaehably connected to the draw bar in position 'for retaining the first mentioned sleeve thereon.

2. In draft apparatus, thecombination, with draft beams, of `stops extending between and connecting said draft beams, a draw bar extending through said stops, said draw bar being formed with a shoulder adjacent one of the stops, a sleeve mounted on the draw bar and formed with a shouldered portion adjacent another of the stops, means for retaining the said sleeve on the draw bar, andlstress transmitting means adapted to engage the shoulder of the draw bar and the shouldered portion of the sleeve.

3. In draft rigging, the combination, with draft beams, of cross stops connecting the cross plates and spaced connecting plates connected to said cross plates, the draw bar extending through said stops between the upper and lower and spaced plates thereof, and means for transmitting stresses' from the draw bar to the stops.

4. In draft rigging, the combination, with same and each comprising upper andlower cross plates and spacedl connecting plates connected to said cross plates, the' draw bar extending through said stops between the upper and lower and spaced p'latesvthereof, and means for transmitting stresses from the draw bar to the stops, the said spacedconnecting plates' being spaced .a distance sufficiently greater than the cross sectional dimension of the draw bar for' allowing radial swing thereof.
