Figure 10 is a perspective of the plate used The lower compartment 3 supports a forward aheadof the batteries for supporting the metallic lens 2tv adjustably mounted in a supporting ring 55 23 which also supports a reflector 24 and a light bulb 25.

Batteries

25 and 21 supply the current for bulbs 8 and 25 and are operatively contacted with each other by contact member 28 while bulb 25 makes a constant resilient contact with strip 29 while the current from

batteries

26 and 21 passing through wire 38 back to the rear of casing makes resilient contact with switch member 3| through wire 30.

As an explanation of the switch control lights 8 and 25 it may be said that the single control member 34 is adapted to be slidably moved in a slot 4| in insulating plate 31 and this control member has a contact end 38 pressing against the

switch members

33, 39 and 40; as the single contact member 33 touches the battery 26.

It will thus be noted that when it is desired to turn on light 8, then the switch control member 34 will be slidably moved over tocontact switch member 43 so that this member 40 may be placed over against contact member 35 which will carry the battery current to light 8. Where it is desired to have both lights 8 and 25 on at the same time, then switch control member 34 is moved over in slot 4| far enough to press against switch member 39 in the middle moving the same out to meet contact members 3| and 35 which will carry current to bulb 8 and bulb 25 but where it is desired to turn on only bulb 25, then the switch control member 34 is moved over in slot 35 far enough to meet switch member 33 causing the same to meet switch contact member 3| carrying the battery current from member 32 through contact member 3| by touching switch member 33.

It will be noted that the battery contact 32 and the

switch members

33, 39 and 40 are all integral, while switch member 4U touches contact 35 when pressed into engagement therewith, switch member 39 touches both contact members 3| and 35 when pressed into engagement therewith by slidably moving control member 34 and switch member 33 touches contact member 3| when turning on light 245.

It will be observed that when

screws

2, 3, 4 and l5 rest in

cross slots

36, 31, 38 `and 39 that any lateral adjustment desired may be made in the supported position of light 8 and reflector l0.

In this lower compartment is also mounted a partition and conductor member 40.

In Figure 7 will be observed the revolver type form of my casing wherein the grip member 4 slidably engages a revolver barrel not shown as this grip is slidably adjusted in groove 5.

In this form of my casing, I secure the planoconvex lens 1 in the forward end of upper compartment 4| in connection with which I provide the reector tube 42 extending from lens 1 back to the mounting for bulb 43 which is mounted for lateral adjustment in ring 44 having adjusting screws 45 and 46, with screws 41 and 48 not shown.

In ring 44

screws

45, 46, 41 and 48 are respectively mounted for adjustment in slots 49, 50, 5| and 52.

The shape of this casing requires an arrangement of the

batteries

53 and 54 in a manner permitting battery 53 to be supported in the upper compartment 4| of this casing 55 vrith battery 54 resting parallel with battery 53 but in lower compartment 56 of this casing the closure member for this casing is the same in construction as closure |1 for the first form of my invention shown in Fig. 1 and will be so designated while the latch members are the same.

I provide a lower light bulb 51 mounted in socket 58 at the forward end of lower compartment 56 in casing 55 while I provide a partition plate 59 rearward of bulbs 43 and 51 and forward of

batteries

53 and 54 to provide a partition between the batteries and light bulbs as an insulation member and yet to support the contact member 6B which establishes connection between

batteries

53 and 54 and bulbs A43 and 51.

I secure a series connection between

batteries

53 and 54 through contact strip 6| which conducts the current from the forward end of battery 54 back between them to the rear end of battery 53.

Thus it will be observed that in this type of my invention, while it would be convenient and practical to have the lights turn on one at a time yet it is thought that it will be most desirable to have both lights in most cases turn on at the same time.

Switch contact member 62 is made to contact with battery 54 and is turned on by switch control knob 63 mounted in closure member |1.

It will be observed in connection with my invention that I provide in the electric light bulbs 8 and 43 for instance, a filament that is peculiarly designed and effective for this invention; wherein the filament being coiled from one end to the other in the direction longitudinally aligned with the tube in which it is mounted. Thus by ceiling this filament in alignment with the reflector tube there is secured on the bright spot of light a circular image of the filament making the focused spot of light more readily observed.

It will be noted also that lens 1 is especially manufactured for this particular target range finder and this lens is shaped in a manner making it fiat on one side and also flat on the other side with the exception of a central smaller middle portion which is convex. The purpose of this type of lens seen used with reector tube I6 is to provide means for throwing the illumination which passes through this lens much more brightly and greater around the focused spot of light, thus better illuminating the target and its surroundings.

With this construction this invention establishes a substantial improvement over the novel features shown, described and claimed in my former application and what I claim in this new and improved invention and desire to have protected, is:

1. A night target range finder for guns comprising a two compartment casing provided along the top with an elongated resilient grip slidably secured to the casing for engaging a gun barrel for the support of the casing, the upper of said compartments in the casing provided with a light, an adjustable mounting for the light, With a plurality of adjusting screws; said mounting with said light disposed adjacent the rear of the top compartment in the casing, a lens adjustably mounted in the forward end of said upper compartment; said lens having a central concentrating portion and a peripheral portion having plane parallel faces and an adjustable reflecting tube extending a major portion of the distance from said lens to said light and having a greater diameter at the rear end than the front end, an integral second and lower compartment in said casing, an electric light mounted adjacent the forward end of said compartment, and lens means cooperating with said light, batteries mounted in said casing and operatively connected with both of said electric lights and an electric switch op eratively connected in the circuit between said batteries and said lights for the selective control of said lights; whereby the operator may turn on either light by itself or both lights together and whereby said upper light with its lens may focus a bright spot of light on a target and whereby a ood of light may be thrown about said focused spot of light when desired.

2. A night target range nder for guns comprising a two compartment casing provided along the top with an elongated resilient grip slidably secured to the casing for engaging a gun barrel for the support of the casing, the upper of said compartments in the casing provided with a light, an annular mounting band for the support of the light and provided with a plurality of transverse slots, adjusting screws supporting the light and respectively held in said slots for the selective lateral adjustment of the light; said mounting with said light disposed adjacent the rear of the top compartment in the casing, a

lens adjustably mounted in the forward end of said upper compartment; said lens having a central concentrating portion and aperipheral portion having plane parallel faces and an adjustable reflecting tube extending a major portion of the distance from said lens to said light and having a greater diameter at the rear end than the front end, an integral second and lower compartment in said casing, an electric light mounted adjacent the forward end of said cornpartment and lens means cooperating with said light, batteries mounted in said casing and operatively connected with both of said electric lights and an electric switch operatively connected in the circuit between said batteries and said lights for the selective control of said lights; whereby the operator may turn on either light by itself or both lights together and whereby said upper light with its lens may focus a bright spot of light on a target and whereby a flood of light may be thrown about said focused spot of light when desired.
