IMPROVEMENT LQCOMOTIVE ANT: TENDER-COUPLING.

The Schedule'refrred to in these l-etters Patent and making part of the same 1'0 allwhom it my concern.-

Be it known that I, THOMAS D. SIMPSON, of Mount Vernon, in the'county of Knox and State of Ohio,

--haveinvented a new and useful Improvement in Coupling; and I do hereby-declare that the follow-, ing isa full, 'clear, and. exact description thereof, which will. enable others skilled in the art to make and use'the :same, reference being bad to the accom=- panying drawing forming part of this specification. Thls invention relates to anewand useful improvernent in a device. for coupling a locomotive to the tender, whereby the connection is made more perfect than it has hitherto heen,'aud whereby the traction power of the locomotive is increased; and i It consists in the construction and arrangement hereinafterdescribed.' i

. In the accompanying"drawing+f h Figure 1 is a side "iew'of the coupling, shown as applied tofa locomotive and tender.

- Figure2 .is a sectional view of the under side of the tender, showing the position of thepulling-bolts.

Figure 3 is a view of theffront end of ,the tender,

showing-the block .by means of'iwhich the coupling-,

bar is adjusted.

Similarletters'of reference indicate corresponding parts.

A represents the foot-board of the engine;

B is the coupling-bar; I

. O 'isthe coupling-block -D represents long bolts, (four, more or less,) extendihgfrom one-end ofthe. tender to. the other, called pulling-bolts. Y

The coupling-blocks C are the same on each end of the tender, andthe pnlling bolts D pass through them, as seen atE in the drawing.

is a joint in the coupling-bar B. -It will be seen that the coupling-bar stands at an angle, the back or F represents the coupling-pins, applied as seen in.

tender end being considerably the lowest, and that it may be so adjusted on the block 0 as to drop more or less, as may be desired. I

By this means the weight of the tender is made to bear, more or less, upon the driving-wheels of the locomotive, and'thereby increase the traction or adhe- V ,sive power of those wheels to the rails.

The tendency of the pull of the locomotive is to raise the forward end of the tender, audthe harder the pull the greater will be the tractive power of the engine.

This arran filllellb revents thesli in" of the drivg D ID a:

steam occasioned thereby.

In slackening thespeed or stopping, or in backing,

thejoint G in the coupling-bar willgive, and allow the engine to push back ona levelwith the tender.

If. the coupling-bar was a single piece, or. rigid, the tendency in backing would be to raise the engine from the track, 'but the joint prevents it. I

By applying the two coupling-blocks O to the tender connected by the pulling-bolts, as seen in the drawing, the entire improvement may be applied in coupling any locomotive and tender, thus increasing the power of the engine, and saving time as well as Steam.

1 Having thus described my invention,

I claim as new and desire to secure by Letters Patentj Th'e recessed platform A of the locomotive, and the jointed link B pivoted therein, in combination with the coupling-block '0, provided with three or more re.-

cesses, and with pulling-bolts D of the tender, all said parts being constructed and arranged as herein shown and described. v v
