Application January 14, 1952, Serial No. 266,359

2 Claims. (Cl. 421) This invention relates to new and useful improvements in sight devices for firearms and the primary object of the present invention is to provide an illuminated sighting device for firearms so constructed as to permit a user to view a target under poor lighting conditions without clearly revealing his location.

Another important object of the present invention is to provide an illuminated sighting attachment for firearms including a switch button that is so located as to be activated by a finger of a users hand gripping the stock of the firearm in a normal manner.

A further object of the present invention is to provide a sight unit attachment for firearms that will in no way interfere with the use of the firearm and which attachment may be quickly and readily applied to or removed from a firearm, for inspection, repair or replacement, in a convenient manner.

A still further aim of the present invention is to provide a sight light device of the aforementioned character that is simple and practical in construction, strong and reliable in use, small and compact in structure, neat and attractive in appearance, inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being bad to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a fragmentary side view of a firearm and showing the present invention mounted thereon;

Figure 2 is an enlarged longitudinal vertical sectional view taken substantially through the center of Figure 1;

Figure 3 is an enlarged fragmentary horizontal longitudinal sectional view taken substantially on the plane of section line 3-3 of Figure 2; and

Figure 4 is a transverse vertical sectional view taken substantially on the plane of section line 44 of Figure 3.

Referring now to the drawings in detail, wherein, for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral represents a firearm having a barrel 12 and a stock 14 including a barrel supporting portion 16.

An elongated tubular casing 18 is removably supported on the upper periphery of the barrel 12. The forward end 20 of the casing 18 engages under the head of a pin 22 fixed to and rising from the barrel, and the rear end 24 of the casing 18 is formed with an aperture that receives a fastener 26. The barrel 12 is provided with a threaded recess (not shown) in registry with the aperture in the rear end of the casing and this recess receivably engages fastener 26.

Forward and rear sight elements 28 and 30 are fixed to and extend upwardly from the forward and rear ends of the casing in front of forward and rear perforations 32 and 34 in the upper periphery of the tubular casing 18.

Forward and

rear lamp seats

36 and 38 are fitted in the ends of casing 18 and are formed with central aper- 7 2,718,724 I Patented Sept. 27, 1955 tures that receive and hold forward and

rear lamp bulbs

40 and 42. Shields 44 and 46 project from the ends of the casing and are secured to the seats orto the casing through the perforations and behind the sight elements.

A recess 48 in one side of portion 16 receives a housing 50 in which a pair of side-by-side batteries 52 are disposed. The bases of the batteries are grounded to the barrel 12 by spring fingers 54 that are suitably held in recesses 56 in portion 16 under barrel 12. The terminals of the batteries project outwardly through apertures in the housing 50 toward a transverse recess 58 in portion 16 along side of recess 48.

The inner and outer

flattened ends

60 and 62 of a switch member or pin 64 are slidably received in recess 58 and wires 66 secured to the pin 64 extend upwardly through a passage in the portion 16 and an aperture in the casing 18 and then to the

bulbs

40 and 42. A spring 68 in the recess 58 behind the head or end 60 urges the end 62 to a position substantially flush with the side of portion 12 in which

recesses

48 and 58 are provided.

One leg of a U-shaped conductor or finger 70 is fixed to pin 64 and is slidably received in a slot 72 between

recesses

48 and 58. The other leg of conductor 70 supports a pair of lugs 74 for engaging the terminals of the batteries as the end 62 of switch button 64 is pressed into the recess 58.

The entrance 76 for recess 48 is slightly enlarged to accommodate the projecting edges of the front wall 78 of housing 50, since these edges constitute finger grips, whereby the housing may be retracted from or inserted into recess 48.

In practical use of the present invention, assuming that the user is grasping portion 16 with his left hand, one finger of this hand may press inwardly upon the end 62 of button 64 to complete the circuit to the lamp bulbs so that sight elements 28 and 30 may be readily viewed.

Lugs 74 are so spaced apart that one lug will engage the terminal of one battery before the other lug contacts the other battery terminal in order to provide a dim lighting of the lamp bulbs. However, continued pressure or sliding of the button 64 will permit both lugs to engage their associated battery terminals to produce an increased illumination of the lamp bulbs.

Having described the invention, what is claimed as new is:

1. In a firearm including a stock and a barrel, a sight attachment comprising an elongated casing supported on the barrel and having forward and rear ends, forward and rear sight elements supported on the ends of said casing,

, a lamp bulb disposed within each end of the casing, said casing having top small forward and rear perforations behind the forward and rear sight elements and over the lamp bulbs, a pair of side-by-side batteries supported inside the stock and grounded to the barrel, and a sliding spring-urged switch member carried by the stock and having thereon a conductive finger for selectively engaging one battery terminal or for simultaneously engaging the terminals of the batteries, said switch member including a pin having inner and outer fiat ends, said stock having a recess slidably receiving the pin, a spring in the recess behind the inner end of the pin, and said finger being secured to the pin, said pin being slidable transversely of and across the batteries.

2. In a firearm including a stock and barrel, a sight attachment comprising an elongated casing supported on the barrel and having forward and rear ends, forward and rear sight elements supported on the ends of said casing, a lamp bulb disposed within each end of the casing, said casing having top small forward and rear perforations behi'ndYfiefcSrward and rear sight elements and over the terminals: of"he"batterie's7saidswiteh member including References Cited in the file of this patent UNITED STA ES PATENTS Hollister May 14, 1901 Schlaegel June 23, 1903 Deere et a1 May 4, 1909 Searcy May 16, 1939
