To all whom it may concern; g 1 .Be it known that I,YELZY R. WIiLIAMS, a citizen of the United States, residing-at "St. Joseph, inthe county of Buchanan and State of Missouri, have invented a certain new and useful Improvement in Trigger Mechanisms, of which the following is a specification. l My invention relates to improvements'in trigger mechanisms. M i i One of the Objects of my invention is to provide a trigger mechanism, of the type havlnga main trigger and an auxiliary or i hairtrigger; which is reliable in operation, which is easily operated, which is not liable togetout of order, and which may bereadilyapplied to fire-arm's now in use. v Y -The'novel features of my inventionare hereinafter fully describedand claimed.

In the accompanying drawings, which illlllstftte thepreferred embodiment of my inve tion, as applied to afir'e-arm having a sliding hammer, v H "Flgure 1 is a side elevation ofa portion 5 of a fire arm which is provided with my i improvement. s s

i Fig. 2. is a rear view, partly broken away, of my improved trigger mechanism. Fig. 3 is a front view,partly broken away, of the trigger mechanism.

In this View, theparts cona. trolledby the auxiliary trigger are shown in the released position. i i

is aview 'milar to Fig. 7, the aux i5 1 iliary. trigger and mechanismcontrolled therebylbeing shown in the set position.

The upper end of the plate 5 is provided with a slot in which is mounted an auxiliary releasing member, preferably comprising a releasing lever 9, which is'pivoted to "the plate 5 by a' tran'sversepin 10. Thereleasing lever 9 carries a transverse pin 11 on which is'mounted a frictionroller 12,which is adapted to strike against an abutment comprising a fixed part 13 of the fire-arm,
