Paten-1396i Aug. 17, M909i W/ TIVESSES Tos all whom 'it may concern.:

Be it known toet l, ifi/irons n. Girnnrrrr,

citizen olf the United States, resirl cago, in thefeounty oit'fook ano nols, have invented nov.' and us iiients'irrlra B21-'remind Ext ionilhanlrs :for Gars, of wjl h the l'ollowing` is a speoiiieation.

By reason oi' he platforms ol 1o cars generally 'bei e. car hody and their t 'icy to ss.,D when snhvjest-red. to strains, it has i ien the praetif to locate the dral'txand.helling springs under the end ofthe-ear body an d hacker the plati'orin'. Thishasrnecessitated the use ol' long7 dreff har of special construction Whit;V not interohangeahlenith the draw har t ronplers es applied to `freight oars. Conseiiently il roads have been obliged to carry in stoel; 2o two or more types of draw hars, one for pas songer carsaiiidanother for freight eqnifp- 11^nent..7 1 The object-oi' my invontion is the provision ol' droit and hurling gear forv passenger cars so constructed that the type of draw har used oni'reight cars can also he used l'or passenger cars.

Thestandard El. (l. B. freight Coupler the end oi the disk har' inf-ide vritl4 veztical holes i'or rivetsor bolts and sometimes vfith a horizontal slot at right angles tothe vertical holes.

A 'further ohjeei ol my invention is to provide such-an arr Angement of the gear as will allorithe use ol either forni oi' the standar coupler, one heing interehangeahle with the other.

My invention oonsists in certain novo1I 'im ol' construction and combinations ol' part L0 hereinafter set lorth and claimed'.

The accom psnying drawing` illustrates one example oi' the physical einliodinient ol niy invention constructed and arranged aon-ording` to the Anest inode l have so lar devised lor i5l the practical application oi the principle.

Figs. i and 2 illustrate the normal attachinent ol the standard draw har and the extension dra-W bar. stilening plates and bolts hold the parts in direct alinernent and are not subjected to strains in huliing. ln drawing the links rclieve the bolts from any serious shearing strains.

- and links removed.

deranged in any Way, on the road or otherwise, another one can be substituted by simy retrieving 'the front key and bolt 13, as obvious.l Under similar circumstances, where a standard coupler and draw bar having the holes and not the slot is only obtainable--such a draw har is shown in Fig. 1- the bolts 13 and la are withdrawn, and the top and bottom plates ll, 1; and the keys Then the coupler and draw bar is placed in alinement, the two links adjusted upon the top and bottoni surfaces of the abut-ting ends of the standard draw bar and the extension draw bar7 and the four bolts passed through the holes in the links and draw bars, as illustrated in Fig-4. In this instance the top' and bottom stiffening plates are not used. However, when snch plates are provided with a plurality of holes, sufficient to allow the bolts to be passed through/the said plates and the end of the standard draw bar, these plates may be used in lieuof the perforated links for effecting the union of the parts.

What I claim is:

l. The combination in a draw bar and extension shank mechanism, of a standard Masyter Car Builders coupler head and shank,

said shank having holes at the end; an extension shank having at its rear end means for.

connecting it with spring mechanism, and its forward end provided ,with holes and means for uniting the coupler head and shank to the extension shank consist-ing of two oppositely applied stiffening plates and bolts, and supplemental metallic means located at right angles to the planes oi the stiffening plates.

2. The combination in a draw bar andeX- tension shank mechanism, of a standard Master Car Builders coupler head and shank, said shank having holes at the end, one of which holes is in a plane at right angles to another;

.an extension shank having at its rear 'end means for connecting it to a spring mechanlsm and its forward end provided with holes, one which 1s at right angles to another;

and means for uniting the coupler headand.

4'. The combination with a standard draw bar having a slot and holes at right ang-fles thereto, of an extension draw har havingl a slot and a plurality of holes; two perforated links; two keys; perforated stilfeningi plates; and bolts secured by nuts.A

5. The combination with a standard coupler and ydraw bar having a slot through the draw bar, of an extension draw bar with a slot; perforated links; keys for securingiI the. links to the draw bars; and means detachably secured to both draw bars for stitfening` the union. 1

6. The combination with a standard coupler and draw bar having' holes and a slot, of an extension draw bar having holes and a slot; links having slots and a plurality of holes and keys for uniting the drawbars through the medium of the links.

7. Anextension draw bar havingI at one end a slot and a plurality of holes at right angies to the slot, and at the other end a slot and a plurality of holes at right angles to the slot.

8.. An extension draw bar having its opposite ends enlarged and each end provided with a plurality of holes and a slot, the holes being` disposed at right angles to the slots.
