IMPROVEMENT IN RAILWAY-SWITCH STAND.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concer-n:
Be it known that we, R. L. MOGOWAX und WALTER FLETCHER., of Alliance, in the Stute ot' Ohio, have in- `vented n new amd useful Improvement in Switch-Stands p and we do hereby dechire thai-t the following is e full,
` tion zuid operation..
Similar letters, in the drawings, refer to like parts. This invention consists in the novel 'construction zuid combination of en elastic switch-lever with a. notched slot in the switch-stand, zuid e sliding key, connected' with the lever, whereby the switch is rendered selflocking, and. is prevented from displacement by any accidentel lateral pressure.
In the drawings, Arepresents switch-stand, of oro dinery construction, longitudinally of which, in thc top,
is a. slot, a, through which passes the switch-lever c,
mede elastic. y
Three or more recesses, w', open out of one side of the slot a, into either of which recesses the lever c' slips, as, in passing along the. slot (t, it comes pposite such recess. v
Ixfthe drawings, the lever is shown its occupying the middle recess, When in this position, it is-obvious thettlie lever is securely locked against any lateral pressure, and this, too, without then-id of holt, bi1-r, or-
pin, or any other device which may be displaced or lost.
To prevent the lever from displacement under trzuisl verse strain, we attach to it the sliding` key l), which, when the lever slips into one of the-recesses, falls; olf
its own accord, into the slot in front' of the lever, eind securelyitstens it.
Then the key is raised out of the slot-,the lev'er may be sprmig out of its recess, luid be moved back' or foith in the slot.
Having thus described our invention,"
Y That we clziim as new, und wish to secure by Letters The lever c, in combination with the sliding keyl b, slot a, :nid-recesses a', substantially es described.
In testimony that we claim the foregoing, We have hereunto set oiu hands, this 8th day of September,
. R. L. MOGOWAN. lVitnesses: WALTER FLETCHER. E. G. BROWN, JOSEPH BARNABY.
