(Application filed Mar. 11, 1901.)

(No Model.)




SBEGIFICATIONfor-ming part of Letters Patent No. 689,547, dated December 24, 1901.

Application filed March 11 1901. Serial No. 50,687. (No model.)

To all whont i-z'; may concern.-

Be it known that I, FRANK D. JAMES, a citizen of the United States of America,and a resident of Seattle, King county, lVashington, have invented certain new and useful ,Improvements in Illuminators for Firearms, of which the following is a specification.

My invention relates to improvements in illuminators which operate conjunctively with firearms as an auxiliary aid thereto, and among numerous objects attained thereby and which are readily comprehended from the accompanying drawings and following specificationis the perfect control of the energizing medium of the illuminator at critical moments and positive. extinguishment thereof simultaneously with the discharge of the arm tively, of aftrigger detached and modified to of with relation to an illuminator for firearms include meanswhereby the illuminator is operatedinde'pendently of the action of the trigger.

Like characters ofrefe'rence designate corresponding parts throughout the several 'views.

Before proceeding to set up any preferred embodiment of this invention the utility therewill be comprehensively set forth, and in furtherance thereof it should be understood that the structural features include any menas by which a primary movement of a pull-0E, as the trigger-finger when lying in operative relation to the trigger of the arm, will induce the auxiliary aid or illu minator to act; there by rendering the, said aid operative without additional elfort, delay in aiming, or disalinement of the arm pending action, and, furthermore, rendering the arm operative in the ordinary and customary manner without requiring an unnatural grip or distraction'of thought, as would be attendant in operating means workedby other members of the hand simultaneously with or independently of the movement of the pull off.

bodied in a small-arm, asa revolver, having an illuminator of any ordinary or preferred form fixed thereto in any suitable manner; but the style or form of the arm is immaterial, andthe fixing of the illuminator thereto is a matter of convenience, inasmuch as the invention comprehends any style of percussion firearm necessitatinga pull-off to put it into action and any form of an illuminator primary action of the pull-off.

In the preferred embodiment the firearm consists of a revolver of the ordinary type,

trigger 4, and other usual and ordinary parts. Related to the arm is an illuminater, as 5, consisting of areflector-tube 6 and intermittently-operative means for illuminating, including an ordinary electric lamp '7 and an energizer or accumulator 8 in the form of a battery of any suitable or ordinary construction. The illuminator 5 as now included is conveniently fixed beneath the barrel 3,with the reflector-tube extending para llel thereto, so as to cast the reflected rays forwardly of the arm and preferably in direct alinement therewith, so as to flood' the field of action with light when the lamp7is energized. For convenience the battery 8 is placed within the handle 2 ofthe arm at the base of-the butt, Fig. 1, and may be constructed of suitable form to fit between the detachable side pieces 9 thereof without requiring modifications in constructing'the arm. The lamp 7 .is suitably fixed at the base of the reflector- 'tube,' with one terminal connected to the adjacent metallic portions of the arm, and one pole of the battery is also'connected to adjacent metallic portions, while the opposite terminal and pole of the lamp and battery are included in a suitable open electrical connecfrom one pole of the battery, respectively, to

trigger of the-piece.

adapted for conjunctive codperat-ion with the comprising a framel, handle 2, barrel 3, ,1.

As now'considered, the invention is emtion insulated from the metallic portions of I This connection consists in the separated points adjacent the position of the 1o operatedby 15 push-button,

To effect an illumination, the circuit between the battery and lamp is conveniently closed by primary action of a pull-off or the trigger-finger when lying in operative rela- 5 tion to the trigger 4 and is preferablyaccom-.

plished by a slight movement of said trigger to effect a connection of the wires and 11, Fig. 1, or the said connection maybe efiected by providinga snitabie contrivance, likewise the primary movement of the pull-off or trigger-finger, but leaving the said trigger in action, Figs. 3 and 4. As new considered, this cont ivance is preferably mounted on the trigger and comprises a suitable as 12,-operatively mounted in the face of the trigger at a point where the trigger-finger normally plays in operatingthe arm and has asuilable projection therefrom,

so that primary movement of the finger will first depress the button and complete the'circuit-to cause an illumination prior to perceptible movement of the trigger.

The push-button 12 is conveniently provided with a-stem l3 and is operatively mounted in a suitable recess, as 14, formed in the trigger, with the stem projecting rearwardl y, and acoiled spring, as ]5,under the head of the button serves to return it to normal position after each operation. The wires 10 and 11 ;o are brought into'operaiive relation to the end of said stem in any convenient manner, as v through suitable ways conveniently formed in thetrigger, and the ends thereof lie in a suitable recess, as 16, formed in the rear edge- 5 of the trigger, which recess is closed by a suitable-removable cover 17. One of the wires, as 11,is preferably fixed to the stem 13 bya suitable insulated connection,.while the second-wire is so positioned as'to be contacted o bythefimt when the button is depressed,

' aud-thereby render it possible to produce a continuous or flashing light without movement of'the-trigger. When desired toclose the-circuit by movements of the trigger, one oi -thewi1'es,-as 10, is fixed thereto by a suitableaiusulated connection, and-the second wire, 38-211, is conveniently set so as to be contacted by. the first as the trigger is moved,

render'lt possible to-obtain a I and thereby 1 continuous light by holding the trigger in a slightly-retracted position or a flashing lightby'mo-vingthe trigger reciprocatively.

It will *be understood that the free ends of Witnesses:

r the wires 10 and 11 are conveniently provided with suitable electrodes of any ordinary or desirable construction, which render the connection by contact more positive than would the bare ends of the wires if left in their usual form. v

The firearm thus produced operates substantial] y as follows: Granting an emergency at night, the arm is grasped in the usual manner, with the trigger-finger resting in-the guard, and is pointed in the supposed direction of attack. Slight pressure is then applied to the trigger, with a resultant flash from the illuminator, which exposes the field of operation, followed by the usual full movement of said finger, if desired to discharge the piece. As the piece is fired the trigger ryturns, as usual, consequently separates the electrodes on the wires and insures the instant extinguishment of the light, and the operator is thus aprotected by the darkness.

Obviously an illu miinatorand firearm placed .at separate. points can bra-cooperatively con.-

nected in a manner substantially equal to the disclosure and other means than the trigger-finger em ployed to efiect operative movement of the means for energizing the illuminator and to simultaneously place the piece under operative control of the means for ef-, footing said movemen Having thus described my invention, what Iclaim as new, and desire to-secu re by Letters Patent of the United States, is-- l.
