ATTORNEY United States Patent O 3,510,965 TRAINING AID FOR SIGHTING SMALL ARMS Don E. Rhea, 148 Wilson Ave., Placentia, Calif. 92670 Filed Apr. 14, `1967, Ser. No. 630,922 Int. Cl. F41g 3/26 U.S. .Cl. 35--25 5 Claims ABSTRACT F THE DISCLOSURE An electrically' actuated light bulb and focusing lens which inserts into the barrel of, for example, a revolver. Energyfor lighting the bulb is connected to one electrode of the bulb through the portion of the device in the barrel and to the other electrode through the metal portion of the .,revolver. When the trigger` is pulled, the ring pin strikes the cartridge unit in the chamber for completing the electrical circuit. Light from the bulb appears, for example, on a target Where the revolver was pointed.
BACKGROUND OF THE INVENTION Field of the invention The invention relates to a training aid for improving the sighting of small arms and, more particularly, to such a device wherein light is emitted from the training aid when the trigger is pulled for completing the electrical circuit.
Description ofprior art Applicant is unaware of any prior art directly to the present invention. Presently, in order for a user to develop t a .fee1.for a weapon, it is necessary to spend innumerable hours at a firing range. Countless rounds of ammunition may be expended before a rer is assured that he is properly sighting the weapon. In other words, before skills and accuracies in the use of a weapon can be developed, and individual must practice tiring. When he is more familiar with where the bullet will strike when the trigger is pulled and with the weight of the weapon, his skills and capabilities improve.
Often, however, it is difficult to go to a tiring range. Weather, distance, or availability may reduce the practice individuals such as law enforcement oicials, sportsrnen and other require. In addition, the use of firing ranges including ammunition expended, is relatively expensive.
Theuse of live ammunition while a beginner in adjusting to a weapon may constitute a hazard as well as an expense.
Desirably, a device should be provided for permitting practicing without the necessity for extensive practice at the firing range. A training aid should give the individuals indicated above an opportunity to practice and get the feel of a weapon before visiting a range so that better use can be made of their ammunition and time. Hazards should be reduced to a minimum.
Such a development should simulate as nearly as possible the response one expects when firing a gun. Although the sound and recoil cannot be simulated, the reaction of bullet impact should be present. When a person pulls the trigger,` they should be able to see Where the bullet would have struck. lHe can repeat the process until his eye and/ or arm, and gunsight can be aligned for improving his accuracy.
SUMMARY OF THE INVENTION Briey, the invention comprises a device including a portion which inserts into the barrel of a weapon and a second portion for inserting into the tiring chamber of a Weapon. A voltage supply is connected to one portion of I the weapon and to the portion of the device inserted into the barrel. The barrel is insulated from the device initially Patented May 12, 1970 so that the electrical circuit is not complete. The second portion includes a conducting element which contacts the rst portion and the tiring pin of the weapon when the trigger is pulled, whereby the electrical circuit is complete. The first portion includes a lamp source which is actuated when the firing pin strikes the conducting element.v
In one embodiment, the first portion includes lens means and means for changing the distance and direction of the lens with respect to the light source for focusing the light and for directing the light in a preferred direction. In addition, a rod may be provided which has a length for accommodating one type of weapon but which can be replaced by a rod of different length for adapting the device to another weapon having different barrel lengths.
Therefore, it is an object of this invention to provide a training aid for improving an individuals capabilities in handling a weapon.
Another object of this invention is to provide a training aid means for reducing the use of ammunition and firing range time in training an individual to use a weapon.
It is another object of this invention to provide a training aid which reduces the hazards associated with learning how to use a Weapon.
A still further object of this invention is to provide a training aid adaptable for use with a plurality of weapons for improving sighting capabilities.
Still a further object of this invention is to provide a training aid for improving an individuals sighting capabilities with the weapon.
Still another object of ths invention is to provide a training aid for sighting practice of a weapon simulating certain aspects of the use of live ammunition.
These and other objects of this invention will become more apparent in connection with the following drawings.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 represents a cross-sectional view of one embodiment of a training aid in a revolver.
FIG. 2 represents an exploded view of the device removed from a weapon.
FIG. 3 represents one embodiment of contacts for supplying energy to the weapon and the device.
FIG. 4 represents one embodiment of the cartridge unit completing the electrical circuit.
FIG. 5 represents a diierent embodiment of a light source usable in the invention.
DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows revolver 1, including barrel 2, and revolving cylinder 3. The cylinder includes a plurality of chambers 4. The revolver also comprises hammer 5 which connects firing pin 6 and trigger 7. When pulled, the trigger actuates the hammer and forces the pin towards a chamber of the cylinder. The dotted position of the hammer represents the position of the hammer when the trigger is pulled.
Training aid 8 is shown inside the revolver. It should be noted, however, that the invention can also be used with other types of weapons, including ries, hand guns, and magazine fed pistols. Portion 9 is in the barrel, and cartridge portion 10 is inside a chamber of the cylinder. Other portions occupy the remaining chambers.
Connector means 11 provides electrical energy to the training aid. The connector includes pronged inserts 12 and 12' which insert into receptacle 13 and 13' of the training aid. The receptacles are integral with contact ring portions 14 and 14 which are insulated from each other by insulating washer means 15 (FIG. 3). The contact ring and insulator washer are circular in conliguration and include centrally disposed openings 18 and 18 (FIG. 3) for accommodating hollow tube means 16 0f the training aid.
A more detailed View of the receptacles, etc. can be seen in FIG. 4. As indicated in the figure, the receptacle form female members which engage the power connection prongs. The contact rings may be stamped or otherwise formed from relatively flat metal elements which convert voltage from a source (not shown) to the aid and revolver. The insulator may be molded from a plastic or non-conducting material for insulating the contacts from each other. The contact rings are relatively flexible so that during assembly they can be spread apart for permitting insertion of the insulator as shown in FIG. 4. The insulator includes an extension on both sides of centrally disposed flange member The extensions insert into the openings of the contact rings, partially into the barrel, and into indentations of ange portion 17. In other embodiments, the extensions may be shorter and not extend into the barrel or flange portions.
Ring 14 contacts the end of barrel 2 and forms onehalf of an electrical circuit, with the hammer and ring pin. Ring 14' contacts flange portion 17 of the bore tube for forming the other half of the circuit. The electrical -circuit is not completed until the firing pin contacts the cartridge in the chamber. When that occurs, light means 19 becomes energized and emits light. In other words, energy to one electrode of the light means is conducted to the light means through the training aid in the barrel and energy to (or from) the other electrode for completing the circuit is conducted through the metal portion of the revolver. It should be noted that although energy is supplied initially at the barrel, the power source could be connected at any point of the Weapon.
FIG. 2 shows an exploded view of the training aid illustrated in FIG. l. The device comprises contact rod means 20 which forms a metal rod for contacting one end of the cartridge portion and one electrode of the light means, such as a low voltage lamp. By changing the length of the rod, the device can be made to t other weapons with different barrel lengths. At the end of the barrel adjacent to the cartridge unit, the rod is insulated from the barrel and restricted from lateral movement by sleeve means 21. The sleeve is circular for being inserted into the barrel and may be comprised of a plastic or other non-conducting material. O-ring member 50v is placed about narrow necked portion 22 of the sleeve means for holding the sleeve Within the barrel portion. The sleeve is threaded on the inside for mating with the threaded portion 23 of the bore tube means.
The rod includes head portion 24 which has a larger radius than the longitudinal portion. Rod spring means 25 is inserted inside the contact sleeve means around the longitudinal portion of the plunger. The sleeve has an enlarged opening with a depth sufficient to accommodate the spring. The spring provides tension to insure good contact between the head portion of the rod and the base of light means 19.
The front end of the light means inserts into portion 26 of the barrel bore tube means. Portion 26 is hollow, as is the remaining portion, but has a relatively larger diameter for accommodating the light means. In other embodiments, the tube means may have a uniform diameter. Flanged portion 27 of the light means prevents it from being pushed completely inside the bore tube means and out of contact with the head of the rod. 'Ihe bore means includes narrow necked portion 28 and 29 into which O-rings 51 and 52 insert for holding the tube inside the barrel. The tube includes lianged portion 17 at the termination of the tube means for contacting ring portion 14. Connector 11 is shown out of contact for convenience. When assembled, the connector would appear as shown in FIG. 1.
Lens holder 33 comprises a cone-shaped portion having contoured portion 34 for forming a swivel with respect to the end of barrel 2. The shape is not essential, however. Other shapes are within the scope of the invention. As a. result, the direction of a light beam from the light means for directing the beam can be adjusted to- Wards a desired point relative to the gunsight. Lens 35 inserts over the end of the holder for projecting the beam to a target area. The lens is held in place by lens lock link 36 comprising a split ring fitting inside the rim of the lens holder.
Lens holder spring 37 comprises a conical compression spring formed to tit over the base formed by bushing member 38. The spring presses against the lens and the bushing member. Bushing member 3S includes threaded portion 39 for securing the holder to the tube. The tapered end of the spring has a diameter large enough to permit light from the light means to pass unimpaired to the lens. The spring diameter increases in accordance with the increase of the diameter of the lens holder. Focus bushing spring 30 inserts into the opening of flanged portion 17 and presses against the surface of bushing member 38 for increasing the friction between the threaded portions which prevents vibration and changes in the focus position of the lens. The spring inserts inside threaded portion 39. The friction between the lens and the bushing permits the holder assembly t0 be adjusted to a desired position and held in that position. By turning the lens holder, the bushing moves in or out of the tube portion for changing the distance between the lens and the light means. As a result, the lens can be focused.
As shown in FIG. 4, cartridge l0 comprises casing 40 formed from a plastic or non-conducting material and having a size and shape required for the calibre and model of weapons into which the cartridge is placed. The cartridge includes ball means 41 at one end of the casing. The opening of the casing at that end if slightly reduced to prevent the ball from being forced out of the casing. The ball is xed against the end of the rod means by spring means 42. One end of the spring presses against the ball and the other end presses against tiring pin contact 44. Bushing 43 includes a cylindrical protrusion which inserts inside the casing. An adhesive can be used to hold the cartridge unit together. In other embodiments, the parts could be threaded. The bushing is also comprised of plastic or non-conducting material. Threads are shown in the tigure.
Firing pin contact 44 includes narrow neck and solid portion 46 which inserts into an opening in the bushing so that the end of the portion is approximately ush with the back of the bushing. Flanger portion 31 contacts the narrow portion of the bushing and prevents the pin from slipping out. The other end of the contact inserts inside the spring. The outer diameter of the spring and the outer diameter of the anged portion are approximately equal.
In a different embodiment, instead of using a light means with a tlanged portion, the sleeve means of FIG. 2 could be provided with two sets of threads of different diameters as shown in FIG. 5. The rst set 32 could be used to engage portion 26 of the tube means and the second set 47 could be used to engage threads 48 about the base of the light means.
In addition, although not shown, the irst and second sets of threads could be disposed parallel to each other so that instead of the tube means being threaded about its outer diameter, the tube means could be threaded along its inner diameter for engaging the first set of threads.
Although the invention has been described and illustrated in detail, it is to be understood that the same is by way of illustration and example only, and is not to be taken by way of limitation; the spirit and scope of this invention being limited only by the terms of the appended claims.
