mrnovnmem 1N RAILWAY GATES.

I The Schedule reerredt?V in theseLetters Patent and making paxt ofthe same.

l Be itv known that we, JoHNB. RmnENHocsE and `JOSEPH COLLINS, of Locust Lane, in the county of Indiana and State of `Pennsylvania,have invented 'a new and improved Railway-Gate; andwe hereby declare that the following is a full,l clear, and exact description of -`the construct-ion `and operation of the same, reference being had to the accompanying drawing making part of this specification, in which- Figure 1` is a transverse sectional elevation, and Figure` 2 is-a plan view.

T-his'invention. has for its object to enable a locomotive-engine to automatically open the vgates placed 1 across 'a railway-track,`for the purpose of preventing 1 fcattle i'om straying thereon to places whither they i `should not wandel'.

`The invention consists in connecting the pivoted gate-posts by meansof stifi` rods, with bars laid along `the track, in such `position that the locomotive may i; :strike them, thrust tliemito each side, and thereby `causethem to tnrnthe'gatcs open by means of the` `connecting-rods, the bars 4being furnished with springs which throw them into their original position asA soon v as the train has passed.

1n thedrawing` Al A are thetrack-rails. g

a a are bars, of wood or iron, or both combined,

whose ends are vpivoted to oneof the ties at b b', ontside the track, while 'their opposite extremities lieon the rails A, iinshiwith the inner` lsides 'of the same,

c c are bars similar in altrespects to the bars a, to which they are jointed at the ends between the @gate flames, While the opposite extremities ofthe bars e are pivoted to one of the ties at the points ll Z, ,on` the other side of the gate from thepoints b l1,

13 where the barsa are pivoted.V

G C are the gates extending directly across the track and meeting at the center.` l The gates are set in vertical posts e, which form a the central standards of thev side frames B, the posts c having cylindrical tenons at top and bottom, which n l cntermortises made to receive them in the tie h, and gi' also in the lateral beamsB B, placed at the tops of the side standards, so that theposts c may' swing v easily.

-Rods t t, Vparallel with the gates, connect one of the bars c with the `gate-posts, by means of staples protruding from the sides of the latter.; hence, when the A locomotive strikes the bars a 'or c, according to the d1- rection in which it moves, it throws the bars to each side, and, by means of the connectingrods t', throws open the gates in opposite directions. 1.

As long as any part oi' the train is between the bars the gates are in this manner held open, but, as s'oon as the train is clear of thebars, the springs lt lc, one of which is coiled Vabout the side vertical standard l, and bears against one of the bars c, and the other of which is coiled around the side vertical standard m, and bears against one of the bars a, press the bars a cinward to their former position, where `they lie in readiness for the next train. y

The rods i serve also as stops, to limit such inward ovement of the bars a c, under the impulse of the springs. i

The bars c and a are rabbeted, so that vthose parts of them which extend beneath. the cow-catcher may be of the requisite thinncss, two inches, and the remaining portion outside the cow-catcher may be at 'least four inches thick.

'Phe cow-catcher is provided with friction-rollers, which strike the raisedparts of thebars and throw them open.

lhe thin parts of `the bars extend inward to the wheels, and by them the bars are held open.

Having thus. described our invention,

What we claim as new, and desire to secure byl
