Q E E a nu. 1 v0 w t me gm Warrant,

T w M4 V6 55 48. The member 46 is fixed in any suitable manner to the framework of the gate supporting means. The, inner end of the bar 47 has a projection 4:9, which is rotatably fixed to the end of the pin &4, so'that,'as the pin moves longitudinally in the member 24, the bar 47 will be moved longitudinally in member 46.

In operation, as the motor rotates, the weights 42 will tend to fly outwardly, and, by means of the connecting members, to push outwardly the bar 47. Normally the roller 48 is in the slot 51 of the guide bar 50 and against the edge of the rack 16 which is adjacent the motor. \Vhen, however, the rack has reached the maximum elevation, the roller 48 will pass under the end of the block 53 fixed to the lower end of the rack, as indicated by the dotted lines in Fig. 4, and will thus hold the rack in the elevated position. 7

lVhen the train reaches the switch 27 it will be opened by the train wheels and the roller 4:8 from under'the end of the rack 16.

The racks will then vpress downwardly and rotate backwardly the mechanism by virtue of the weight of the gate, and the gate will thus pass downwardly to normal open position.

I claim as my' invention:

1 The combination of a gate, means for elevating said gate, means for supporting said gate when elevated, means for starting said elevating means, means for stopping said elevating means, and means operated by said elevating means for withdrawing said supporting means when said elevating means stops.

2. The combination of a gate, gate elevating means, and gate supporting means, said latter means comprising centrifugal means operated by said elevating means.

3. A railway gate, a member fixed to said gate, means for elevating said gate, a support for passing under said member when said gate is elevated, means operated by said elevating means for forcing said support under said member, and means'for withdrawing said support when said elevating means sto'iis.

In testimony whereof I hereunto set my hand in the resence of two witnesses.

F ORENCE A. STRIETER.
