In the drawings V The forward end of the bolt 15 is formed Figure 1. is a top plan view of a rail lockwith a beveled striker 21, which as the ing device embodying my invention. members are being closed will contact with 59 Figure 2. is'a sectional view of the same the upper edge of the dovetail 13 and force the bolt back against the action of the spring 20.

For operating the bolt 15, there is provided a finger piece 22, which slides on the lower 5 surface of the member 11 and is secured to the block 18 by the screw 19, so that by a pull on said finger piece 22 the bolt 15 will be withdrawn from engagement with the member 10. In the construction shown in Figures 6, 7 10 and 8, the bolt is mounted in the dovetail 14 and a lug 2 1 formed on the member 11, which have alinedholes therein; and a spiral spring is placed on said bolt 15 between said dovetail 14.- and the lug 24; a pin 25 being 15 placed in said bolt 15 to engage the end of the spring 20, to retain said bolt 15 in the normal position as shown.

For operatingsaid bolt 15 against the action of the spring 20, the bolt 15 near its 20 rear end is formed with a vertical slot 26, within which is mounted the arm 27 of a bell crank which is'pivoted in a bifurcated lug 28 formed on the bottom of the member 11; said crank, having an arm 29 provided with a button 30 extending through a hole 31 in the bottom of the member 11 in such a manner that by pressing said button 30 the bell crank will drawback the bolt 15. 7

It is understood that the button 30 may pro- 30 ject beyond the member 11, or be flush with its surface, or be in a depression in the same as desired, or it may be on the side instead of on the bottom. I

It is also to be understood that the looking at bolt 15 may be operated in place of the two methods shown, by a knob, which by the turning of the same will withdraw the bolt, or a key may be used for the same purpose if desired. 40 Having thus described my invention, what I-claim as new and desire to secure by Letters Patent, is.

In a marine hinged guard rail locking device, and-in combination with two engaging 4| rail members formed with recessed ends for attachment to the adjacent ends of the guard rail, one of said members formed with a dovetail slot adapted to engage with a-dove-tail lug on the other member to form a joint between said members a lug formed within the recess of one member, a bolt slidably mounted therein and in the end of said member and engaging the end of the other member, a spring mounted on said bolt between said lug 5 and the end of the member to retain said bolt in a locked position, and a releasing finger operated means secured to said bolt for withdrawing the same.

In testimony whereof" I afliX my signature.
