Application filed January 23, 1905. Serial No. 242,395.

To (if/ZZ 71172/0711, llt 'nt/,mj con/cern.'

Be it known that I, JoiIN J. Hasan, a citizen o'l the United States, residing at Beaver Crossing, in the county of Seward and State of Nebraska, have invented a new and usetul Traction-Coupler, of which the following is a simple and convenient manner.

Another object of the invention to embody the same in such torni as to permit ol' it being mounted directly upon the tongue or draw-bar of the separator and capable of adjustment longitudinally and laterally to accommodate the device to the position el: the traction-engine with respect to the separator. W'ith these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims7 it being understood that changes inI the form, proportion, size, and minor details may be made within the scope ofthe claims without departing Yfrom the spirit orsacri'ficing any oi the advantages oi the invention.

Aln the accompanying drawings, Figure lv is a plan. view oi a coupler mounted upon. the tongue or draw-bar oi a separator with the shiiitable draw-bar member extended. Fig. 2 is adetail perspective view showing the shi'ltable draw-bar member 4swung to one side. Fig. 3 isa crosssectional view on the line 3 3 of Fig. l. Fig. d is a sectional view on the line LL 4 of Fig. l. Fig. 5 is aflragmentary detail plan view with the shi'litable drawbar member at its rear limit.

Lilie characters of reference designate corresponding parts in each and every iligure of the drawings. n

As embodied in the accompanying drawings the present invention includes a stationary draw-bar member l, which ordimirily the tongue of a separator and is preiu'ably formed of spaced longitudinal bars to produce a longitudinal slot 2, said bars being connected at their 'forward ends by bolts C3 and 4 and adjacent their rear ends by a bolt 5. Suitable braces (i extend between the bar :members l and the 'lront truck or axle of the separator, a portion oi.: which has been shown at 7. longitudinallyslotted cross-head 8 is applied to the liront end ot the draw-bar and preferably consists of a metal bar bent to Aiorm an elongated loop with its extremities bent to produce ears or attaching-brackets tif applied to opposite sides oit the liront end olf' the drawbar and secured. thereto by the adjacent bolt l. A Viller member Q, preferably a metal strap bent upon itself, is secured within the `forward end portion oill the slot 2 by means of the bolts 3 and il, the ilront oilI the iiller member being formed into an eye l0, which is Vprojected into the slotted,Crossherul, the Ylront of the latter being bulged or bowed outwardly at ll to accommodate the eye l0. lNithin the slotted cross-head at each side of the eye l() there is a vertically-swinging pivotal latch l2, which is pivoted intermediate ot its ends, as at 13, there being a spring la secured within the adjacent outer end por tion ol` thecross-head and bearing againstthc short or tail end of the latch, so as to yieldably depress said end and elevate the opposite longer end of the latchv above the top of the cross-head, there being a stop-pin or projection l5 carried by the cross-head beneath the tail oi' the latch to limit thedownwail movement thereof.

The movable member oiV the draw-bar consists oll upper and lower `llat metallic bars l and 1.7, which embrace the bar l and are connected at their rear ends by a bolt 18,- working in the slot ot the stationary draw-lun', the YI'ront ends of the bars being (ainnected by a bolt lf), whichlies in i'ront oll the cross-head. ln l'ront and rear ot the bolt l0 the bar members ll and l7 are provided with ifi-gistered openings 2() and 2l tor the removalile reception ot headed pins 22 and 23, ol which the pin 25J is designed to engage the eye l() when the movable draw-bar member is at its rear limit. The ilorward adjustmeiit ol" the mov able draw-bar is limited by Areason oll the bolt ltl contacting with the rear end of the filler E).

As clearly indicated in Figs. l, 3, and .5,

TOO

the upper part 16 of the movable draw-bar normally lies between the inner elevated ends of the latches 12, whereby the movable draw-bar is held against lateral swinging movements upon the bolt 18 as a center; but either of these latches may be depressed below the upper bar member 16, whereupon the movable draw-bar may be swung to either side of the stationary draw-bar, as clearly indicated in Fig. 2 of the drawings.

lt will of course be understood that either of the pins 22 and 23 may be engaged with the coupling element on the traction-engine when the movable draw-bar is extended; but when the movable draw-bar is at its rear limit, as in Fig. 5, the pin 23 serves to hold the movable bar at its rear limit, and therefore the pin 22 only is capable of being engaged with the coupling element of the traction-engine.

Having fully described the invention,what is claimed isA 1. A traction-coupler comprising a fixed draw-bar, a shiftable draw-bar mounted for endwise adjustment upon the fixed draw-bar, and a coupling device carried by the movable draw-bar.

2. A traction-coupler comprising a fLxed draw-bar, a shiftable draw-bar mounted to swing transversely upon the fixed draw-bar, and latches to detachably hold the shiftable draw-bar in alinement with the fixed bar.

3. A traction-coupler comprising a fixed draw-bar having a longitudinally-Slotted cross-head at its forward end, a shiftable draw-bar pivotally supported upon the fixed draw-bar to swing transversely thereacross, and latches mounted within the slotted crosshead for engagement with opposite sides of the shiftable draw-bar to hold the same in alinement with the fixed draw-bar.

l. A traction-coupler comprising a fixed draw-bar, a shiftable draw-bar mounted for endwise adjustment upon the fixed drawbar and capable of swinging transversely thereon, and latches to detachably hold the shiftable draw-bar in alinement with the fixed bar.

5. A traction-coupler comprising a fixed draw-bar having a longitudinally-slotted cross-head at its forward end, a shiftable draw-bar pivotally supported upon the fixed draw-bar to swing transversely thereacross, and spring-pressed latches pivoted adjacent their outer ends within the slotted cross-head with their inner end portions yieldably elevated above the top of the cross-head and spaced to engage opposite sides of the shiftable draw-bar to hold the latter in alinement with the fixed draw-bar. l

6. A traction-coupler comprising a fixed draw-bar having a longitudinal slot, a member secured within the slot and provided with an eye, an endwise-shiftable draw-bar having a part working in the slot and limited in its forward movement by the member in the slot, said shiftable draw-bar having an opening for alinement with the eye, and a removable pin for engagement with the opening and the eye.

7. A traction-coupler comprising a fixed draw-bar having a longitudinal slot, a metal strap folded upon itself and secured within the slot, the bend of the slot being formed into an eye, an endwise-shiftable draw-bar comprising opposite members slidably embracing the fixed draw-bar and connected by a fastening working in the slot of said fixed draw-bar, the strap lying in the path of the forward movement of the fastening to limit the endwise adjustment of the shiftable draw-bar, the shiftable draw-bar members being provided with perforations for alinement with the eye, and a removable pin capable of engagement with the perforations and the eye.

S. In a tractioncoupler, the combination of a longitudinally-slotted fixed draw-bar, a longitudinally-Slotted cross-head secured to the outer end of the draw-bar with the intermediate slotted portion of the cross-head in communication with the slot of the drawbar, a metal strap folded intermediate of its ends and secured within the slot of the drawbar, the bend of the strap being formed into an eye lying in the slot of the cross-head, spring pressed pivotal latches mounted within the slot of the cross-head at opposite.

sides of the eye with their inner free ends normally elevated above the top of the crosshead, an endwise-shiftable draw-bar comprising spaced members slidably embracing the slotted portion of the fixed draw-bar, front andrear fastenings connecting the slidable draw-bar members, the front fastening being in front of the cross-head and the rear fastening working in the slot of the fixed draw-bar, the rear end of the strap lying in the path of the forward movement of the rear fastening, a removable coupling-pin piercing the forward end portions of the slidable draw-bar members in front of the front fastening, said draw-bar members being provided with alined perforations for registration with the eye, and a removable pin for engagement with the perforations and the eye, the movable draw-bar capable of being swung across the fixed draw-bar upon the rear fastening as a center and also capableof being held in alinement with the fixed drawbar by the latches.

In testimony that lv claim the foregoing as my own i have hereto affixed my signature in the presence of two witnesses.
