Description

[Detailed description of the invention] Bullet collection device [1st top] This invention is a bullet collection device, especially for rifles and shooting ranges in small arms test facilities and shooting ranges. Capturing bullets and similar projectiles fired from shotguns, handguns, air guns, and similar firearms, etc. It relates to a device used to capture and stop.

Trade-Quantity 1 set 15 Bullet collectors themselves are well-known devices, and have been used by firearms manufacturers and users (military installations) for many years. , a testing range used by police stations, rifle/pistol clubs, and the like. ), and tested small firearms such as handguns, rifles, and shotguns. The need for firing, functional firing, target firing, etc., or the need for used equipment fired at test firing ranges. In the context of a single sentence in which one is faced with the task of simply firing a bullet, the “test” is a small High-load ammunition that is typically 40% or more greater than the standard load imposed on the firearm's barrel. ``Functional firing'' refers to the test of firing a small arms weapon, and ``functional firing'' means "Target firing" refers to the test of firing a firearm for accuracy. It means a test that The purpose of such bullet collectors is to collect lead bullets and other types of bullets. (enveloped or unenveloped), as well as overall bullet ricochet and bullet size. hazards that may injure the shooter or bystanders, such as fragments or large numbers of small metal particles bouncing off. or return with enough energy to collect scrap lead bullets, brass and encapsulated metal. equipment placed at a relatively short distance from the shooter to prevent 0 Well-known bullet catchers include wooden boards, boxes filled with sand, metal funnels, and It operates over the entire range of speed and speed reduction chamber assemblies.

Simply - as an example, the well-known sand-shaped bullet catcher can be used against a concrete wall behind it. There is a large amount of sand in a hardwood box set up in the sand. However, this type of bullet collection device regarding the structural and functional characteristics and the costs associated with the bullet collection device. has numerous drawbacks and inconveniences. - Material requirements for boxes over the years (hardwood and sand) Aside from that, annual maintenance is delayed at 50 weeks or about 8 man-hours. Like this sand/hardwood bullet collectors and disposal of accumulated debris, including transportation to landfill. 5-6 times per year requiring handling of approximately 15 tons of weight per year and The annual expense, including labor, would then be at least about $30,000 plus sand and hardwood. Including the cost of the trees, the total will be at least about $40,000. Furthermore, today Under environmental protection regulations, lead bullets must first be treated to meet new treatment standards. Landfilling is prohibited, except for the separation of lead bullets from sand and detoxification (e.g. For example, thermal oxidation, which has been proposed for detoxification, can easily double or triple the cost of treatment. Resulting in.

On the other hand, mechanical bullet traps in funnels and reduction chamber walls have been on the market for about - more than a century. The collector is specifically designed to address some of the problems inherent in sand-filled box collectors. Designed. Some typical relatively simple bullet collection devices for funnels and chamber walls No. 385,546 (Decanbus 1888), No. 694,58 No. 1 (Leithalin 1902), No. 840', No. 610 (Yspool 19) (2007)), No. 2,013433 (Cashwell 1935), No. 4, 1 26, '311 (Wagner 1978). Somewhat A strong bullet collection structure was published in U.S. Patent No. 2,772,092 (1956). , No. 3゜737.165 (Pensilla 1973), No. 4.512.585 (Barabagio 1985), No. 4,821.620 (Carti et al. 1989) year) stated in the statement.

The first mentioned set of these bullet catchers, to the best of the known art, is a powerful Not designed to withstand the impact of steel-encased ammunition, but relatively Most of today's products are designed to degrade quickly even under the impact of low-power ammunition. Generally used1 Essentially, this is the initial contact area of the funnel and reduction chamber. The steel or similar material from which the forming shock plate is made is determined by its composition (carbon content, etc.) and strength. The impact plate has a relatively large angle ( 30° to 606). large moment and relatively large A bullet that comes into contact with such impact plates at an angle will pass from one of the funnel impact plates to the other. In addition to being able to bounce back invariably at a relatively large projection angle, the circumferential partition wall of the deceleration chamber It eventually collides at a large angle with the inner surface of the Sleep. This not only results in bullet fragmentation and rupture, but also impacts from bullets and bullet fragments. This causes relatively rapid deterioration and frequent perforation of the veneer and reduction chamber walls.

Of course, bullets and bullet fragments escaping from the confinement in the deceleration chamber can be caused by the shooter or bystanders. The bullets pose a risk of injury or death, and are a source of lead contamination in the environment. It also becomes.

However, although well-known and recently patented bullet collectors are available today, they require high creative equipment manufacturing, installation and maintenance costs, and damage from bullet impact, corrosion, perforation, etc. This minimizes the need for frequent replacement of baffle plates and shock plates that are damaged by the process, and lead build-up. and lead layer problems (due to air that must be removed using cumbersome vacuum equipment). The need to control hazardous waste (lead debris) and the need to dispose of hazardous debris (handling, collection). It suffers from a number of drawbacks, including difficulties in handling, separation, transportation, disposal, etc. Furthermore, something like this The bullet collector is designed to prevent the impact plate from being shattered by the powerful ammunition used in the test. and versatility, such as the bullet collection device not being able to be used for testing, functional firing, and targeting firearms. Also, such bullet collectors cannot be used in either handguns or high-powered rifles. The design is limited for use.

One troupe, one dish It is an object of the invention to effectively eliminate the above-mentioned drawbacks and disadvantages of known bullet collectors. The object of the present invention is to provide a new and improved bullet collection device.

Another object of the invention is to avoid bullet rupture and perforation of compartment walls, and to Friction between the bullet and the collecting device compartment wall to reduce damage and corrosion and the formation of lead layers. Minimize frictional contact, etc., and reduce the impact that occurs when the bullet passes through the collection device. Collects lead debris, spent bullets and bullet fragments, envelopes and casings, etc. The shells are placed against the compartment wall of the bullet collector for automatic transfer into a collection container outside the station. Bullet trap configured to virtually eliminate the high energy and large angular impact of the round. The objective is to provide a collection device.

In summary, it is an object of the present invention to a first set of flat plates that are A second set of flat plates spaced in the cutting direction and a circumferential partition wall a used plate having a generally spiral shape and having an end wall constituted by a second set of plate sections; The two sets of chain plates have an inlet opening at the front end. Each of the four sides of the passageway has a mouth and a throat at the rear end through which a bullet can pass, and the throat said passageway communicating with the sacrifice in a generally tangential direction to the sacrifice through a horizontal A well-known bullet collection device that captures a bullet fired along its flight and dissipates its energy. This is achieved by a bullet collection device similar to that used in

Basic improvements made by this invention in this type of general bullet collection device has the following characteristics: That is, the two first plates are placed above the flight path of the bullet. They are arranged below at an angle of inclination between 0° and approximately 15° with respect to the horizontal plane. , the chamber that decelerates and dissipates energy has a horizontal axis between the two end walls and a chain wheel. a circumferential partition wall is formed by one curved extension below the first plate; The inner part of the partition wall in the circumferential direction is cut at the same angle as the inclination angle of the first plate below, and the passage is initially extending from the throat generally rearwardly and then upwardly relative to the first plate, and extending from the throat at a circumferentially intermediate portion; a section extends from the interior generally forward and then downwardly of the passageway and further includes a circumferential section. The end portion of the picture wall extends downward from the middle portion and in approximately the same plane as the upper portion of the first board. The beginning of the circumferential partition wall of the passageway extends rearward and continues into the first plate below. The edge part overlaps with the section, and the partition wall in the entire circumferential direction of the chain wheel is Small curvature curvature of about 15.25 cm (6 inches) or less for low-power ammunition 71° 1c+a (28 inches) or less for small arms and high-powered ammunition. It's below.

Simply - by way of example, the bullet catcher according to the invention, regardless of its performance, Designed for use with manual firearms of the type and all types of ammunition. It has two primary plates made from high-strength steel plate 4 inches thick and is quite large. The length from the entrance opening of the passage to the back of the deceleration chamber is 2.4 to 3.6. m (8 to 12 feet), except for leg 2, from the bottom edge of the bullet collector to the deceleration chamber. The maximum height measured vertically to the top of the The width is between 0.6 and 0.9 Il (2 to 3 feet), with a width of 2 to 3 feet relative to the horizontal plane. The inclination angle of the two first plates is approximately 7°, and the radius of curvature of the deceleration chamber wall portion is approximately 71.1 cm. <28 inches) and the inlet opening dimensions are based on the collector width. 61cm x 61’cm (24 inches x 24 inches) or 91cm x 91cm ( (36 inches x 36 inches) is suitable.

By comparison, it was designed for use in less powerful guns than .22 long rifles. The time collector is constructed of 0.48 cm (3/16 inch) thick high-strength steel plate. The length is 91.4 cm (36 inches) and the height is 71.1 cm (28 inches). The width is 33.0 cm (13 inches), and the two first plates are approximately 12 degrees from the horizontal plane. The width of the entrance opening is 33en x 33cm (13 inches x 13 inches) The radius of curvature of various parts of the reduction chamber wall is approximately 20', 3 cm (8 cm). inches). On the other hand, it is a handgun that is more powerful than a .22 long rifle. in a collection device designed for use and more powerful than a .44 Magnum gun. If not, the collection device should be made of 0.64 cm (1/4 inch) thick high-strength steel plate. It is 127 cm (50 inches) long and 76.2 cm (30 inches high). ), with a width of 40.6 cm (16 inches), and the two first plates are approximately It is inclined at an angle of 7° and the width of the entrance opening is 40.6 cm x 40.6 cm (16 x 16 inches), and the radius of curvature of various portions of the reduction chamber wall is approximately 22. 9 cm (9 inches) is greater than 25.4 cm (10 inches).

In the case of collectors designed for use in air guns, the first plate of the collector is Does not need to be made of steel plate, such as nylon, polyethylene, polypropylene, chloride Suitable self-lubricating plastics and similar materials such as polyvinyl, graphite and similar materials with appropriate additives as required to enhance integrity. It can be made of fiber reinforcement treated with or the like. Integrated molded structure The dimensions of the collection device that can be used are as follows: The radius of curvature of various parts of the deceleration chamber wall is approximately 15 degrees. ．． The other traps mentioned above, except that they are smaller than 25 cm (6 inches). It can be basically the same as the smallest concentrator.

In the basic structure of the collection device according to this invention, the initial part of the deceleration chamber wall is To overcome the bullet's resistance to changes in flight direction that deviate from its straight trajectory. It should be emphasized that this is the most important part for functioning. bullet fragments No destructive damage or perforation of the deceleration chamber wall will occur 1. The first part of the deceleration chamber wall 0 radius of curvature guaranteed to have a radius of curvature greater than the appropriate minimum value This minimum value of is expressed for the reduction chamber when moving along the initial part of the reduction chamber. It has been determined empirically that the projectile is adapted to maintain a minimum value of the side of the bullet that will be affected.

In this way, the impact of the bullet is more evenly distributed along the wall and across large surface areas of the wall. distributed and the tip of the bullet pierces the wall of the deceleration chamber (less than the minimum value appropriate for the collection device). can also occur for a small given collector wall radius of curvature) , the number of bullets is prevented. Therefore, achieving the same effect along the entire circumferential chamber wall Since it is highly required to It will be appreciated that the chamber can be designed in such a way that the

A very important feature of this invention is that, as mentioned earlier, the Orienting the two upper and lower plates (first plate) of Renro at a very small angle of 5° or less That's true. In fact, because of this invention, a bullet flies straight down the path and passes through it. Enter the deceleration chamber through the throat length or exit opening of the is the relatively gently sloped beginning of the circumferential wall of the reduction chamber without collision. Preferably, it is in contact with. However, this happens very rarely So, in reality, a bullet fired into the collection device through the entrance aperture is a normal bullet. In the case of a route, either of the two first plates, -m comes into contact with the lower plate. .

The term small at the knee due to the structure of the passage in which the upper and lower plates are oriented at a small angle. The angle “should be accounted for in relation to the capabilities of the firearm used, with an angle of inclination of 15°” is small if the firearm is an air gun, and a 7° angle of inclination is small if the firearm is a powerful rifle. If a bullet or similar projectile on a small, generally horizontal flight path hits the upper or lower plate. When it collides with the other side, the plate is raised by an angle of about 1°, and therefore the passage The bullet will actually fly directly along the surface of the board through the throat of the board.

Therefore, the large-angle collision plate of the well-known collection device changes the flight direction only slightly. The contact plate acts as a deflection plate, causing the contact plate to bounce off the passage plate at a large angle. A wall designed to block the flight of a bullet along its original path with the risk of ricochet. Excessive angular orientation of the bullet flight path in contacting deflection plates that are not used In this case, the trajectory (mainly caused by the contact angle with the plate and physical characteristics (weight, shape, length, etc.)) It is based on the bullet's "coefficient of rebound". deflected by the plate in contact The latter bullet is slightly away from the plate but not at a sufficient angle to the plate. It continues to fly along the narrow passage until it comes into contact with the other plate and exits the throat or exit opening of the passage. Get out.

Eventually, the bullet will move around the circumference of the deceleration chamber, where the walls begin to slope upward relative to the plate below. It comes into contact with the first part of the partition wall. At this point of contact, the angle of incidence is Being relatively small, the bullet is deflected from a straight path into a curved path. this Therefore, the walls of the chamber with a large radius of curvature have plenty of room, and the bullets with sharp passages have no effect on the walls of the chamber. As a result, it is restrained and the direction is reversed. In this), the m word ``large radius of curvature Pa'' is the name of a small firearm. A radius of curvature of 15.25 cm (6 inches) is described for performance, and a radius of curvature of 15.25 cm (6 inches) Large for firearms, the radius of curvature of 71.1cn (28 inches) makes small arms a powerful radius. For rifles, the upper and lower plates of the passage structure and the first part of the circumferential chamber wall are large. The risk of bullet damage (fracture and perforation) to the parts of the In connection with the fact that the useful life of the collecting device is substantially extended, the collecting device according to the invention The term "impact" as applied to collectors refers to the contact between the bullet and the collector. The bullet is effectively stopped in its trajectory and bounces off the wall at a large angle. Distinguishing from the large angle of contact that occurs in known collection devices that simply return and shatter into fragments. As shown, the contact occurs at a small angle and there is no fragmentation of the bullet from the passage. This is repeated at the knee, which is based on a small angle of deflection.

The bullet is in the deceleration chamber and deviates from the straight trajectory & the circumferential wall of the IA far chamber When the bullet is pushed to the part following the , the contact with the circumferential wall of the deceleration chamber is maintained until the bullet's energy is actually dissipated. held. In any case, it may be necessary to do something other than circumnavigate the entire circumference of the reduction chamber. Ultimately, the bullet passes from the terminal part of the circumferential wall at the edge of the deceleration chamber. down to the beginning of the wall just behind the throat of the passage, passing through the throat at the back of the passageway and into the lower section. It slides and rolls along the plate of No. 1 and is removed from the collection device.

In this connection, the described range of 0° to 15° of the upper and lower plates of the passage with respect to the horizontal plane Although the angular orientation can be applied to any bullet collector according to the invention, , it is appropriate in all cases to use an orientation in the upper range, e.g. between 7° and 15°. It should be noted that this is actually considered. In fact, the collection device above and below the aisle if used only in connection with functional firing or confirmation testing of firearms. The plates are horizontal, e.g. at an angle of inclination of Oo to the horizontal plane, and therefore flat to each other. Orient the bullet in a straight line or at an angle of 1 or 2 degrees to the horizontal. It can be deflected mutually with the direction of flight. The throat leading to the deceleration chamber is relatively narrow, for example The height is approximately 5.1 cm to 6.4 cTIl (2 to 2.5 inches). The orientation of the upper and lower plates of the passageway at the angle of the lower end of the range is determined by the height of the entrance opening of the passageway. This necessarily means that the quality is very low. This is because, for this purpose, the muzzle of a firearm can be placed so close to the inlet opening of the collection device that it can actually be located at the inlet opening. In order to ensure that the inlet opening is incorrectly placed, it is of no importance to functional launch or confirmation test execution. There is no fear of bullets.

However, the bullet collector according to the invention is used for targeting firearms testing. I can do it. For this purpose, the launching platform supporting the firearm must be from the entrance opening of the bullet collector to stabilize the bullet in the flight path before , placed at a far distance, e.g. 22.9~27.4+5 (25~30 yards) be done. At this distance, the risk of a bullet missing a very narrow entrance aperture is large enough; It is advisable to provide a large inlet opening. For this purpose, the boards above and below the passage are horizontal. The length of the bullet catcher is preferably at an angle of at least 7° to the surface. is 3.05+e-3,66+n (10-12 feet), approximately 76. An inlet opening with a height of 30 to 36 inches is provided. Therefore , if the bullet flight path is not actually exactly horizontal, the entrance opening of the funnel-like path is To compensate for the small displacement of the trajectory, the bullet still remains in the entrance aperture. enter.

According to another feature of the invention, this type of bullet is adapted for use with lead bullets. The collection device may be of a commercially available type consisting of a liquid lubricant, such as 4 parts water and 1 part mineral oil. against the inner surface of the circumferential compartment wall of the reduction chamber to direct the jet of white water lubricant. An injection nozzle device is provided in the deceleration chamber. Preferably, the injection is at about 3 o'clock and 5 o'clock. between the positions, e.g. 3 o'clock and 4 o'clock positions, towards the beginning of the wall of the reduction chamber. Ru. This causes the lubricant to flow downwardly over the section of the reduction chamber wall and down the throat of the passageway. and then into the discharge location along the first plate below, preferably the first plate. and finally to a collection container, e.g. at the front end of the first plate below. 208.175 liter (55 gallon) capacity under the appropriate opening provided. It falls into a drum, which is filled with dirt.

Liquid lubricants therefore serve multiple applications. On the one hand, liquid lubricants have a passage structure At the same time, the first plate below and the first part of the deceleration chamber partition wall are lubricated. A film of lubricant is formed on the bullet that is fired into the chamber and comes into contact with the first plate below. The bullet moves by minimizing metal-to-metal contact between the metal surface and the bullet. If the metal is made of lead, it will generate lead debris and cause damage and destruction to the metal surface. will be reduced by a lot. Metal-to-metal contact between the bullet and the collection surface is achieved by lubricating the metal surface. Even with a film, it cannot be completely eliminated, and the generation of lead debris cannot be completely eliminated either. No, on the other hand, liquid lubricants are suitable for cleaning shells, kennisings, spent bullets, and lead It acts as a fluid to flush out intermediate materials such as debris, and the large size particles made by crushing the bullet Lead fragments are contained in the liquid and flowed along the first plate below the passageway with the liquid. Leakage of lead debris (finely divided lead) into the surrounding environment which flows into the collection container along with the liquid. , the problematic health hazards, etc. are effectively eliminated. Yet another effect explains It will become clear as we continue.

According to a further feature of the invention, along the entire length of the reduction chamber approximately the horizontal axis of the reduction chamber; It can be shaped into a 2,54c+a (1 inch) diameter conduit running parallel and The jet inside the bullet deceleration chamber has multiple holes or orifices along its entire length. The injection nozzle device is connected to the collection container by suitable piping, and the pump is connected to the piping. so that liquid lubricant can be circulated from the collection container to the injection nozzle conduit. suitable If the pipe is located above the bottom of the collection container, the pipe should connect to the top part of the collection container. It is continued. This is collected by a pump or a container for circulation to the injection nozzle. Ensure that the liquid lubricant spilled from the container is free of accumulated solids in the collection container. .

i.e., as soon as a solid object, which is considerably heavier than the liquid lubricant, enters the collection container. Allowing the liquid lubricant to collect and deposit at the bottom of the collection container, the liquid lubricant will automatically Purified to prevent #9 debris and other solids from being recycled into the reduction chamber.

According to another feature of the invention, the collection container has a sieve member or a strainer attached to each other throughout the vicinity of the top. An inner member is provided. Preferably, the size of the opening in the strainer member is such that the liquid lubricant allow lead debris carried in the strainer to pass through the strainer member, but large metal Designed to prevent debris, shells, casings, etc. from passing through. Therefore, only the lead layer Collecting at the bottom of the collection container, large objects are trapped on the strainer member.

In this regard, if the bullet collector is not powerful enough to fire lead-free steel bullets or BB bullets, If used only in connection with an air gun, the upper and lower deflection plates must be made of high-strength steel. As previously pointed out, it can be made of any suitable plastic or similar material. . Furthermore, such a bullet collection device prevents bullets and projectiles fired from air guns from collecting lead debris. No liquid lubricant injection and outflow device is provided because there is obviously no risk of causing a problem.

At the same time, the self-lubricating properties of the materials from which the deflection plates and the peripheral wall of the deceleration chamber are made ensure that the collection part and the ensuring that frictional interactions between

The advantages of the bullet catcher according to the invention are various. The concentrator is relatively inexpensive to manufacture, can be configured for easy transport and installation, and has thick walls. and do not require sand mounds or similar backing structures. Also, bullet collector The positioning functions in a variety of ways, including handguns, shotguns, and rifles (including high-powered rifles). ) confirmation test, functional firing, and target firing with one device. radiation, confirmation test (in addition to other necessary items, a more rigid collision plate and a more strongly protected A well-known type of ammunition having dual separate devices for Costs associated with round collection devices can be reduced. However, for safety, High-performance rifles are usually test-fired only at long-distance shooting ranges outdoors. The bullet collecting device according to this invention has a distance between the muzzle of the rifle and the target that is 22°9. Safely operate even in relatively small rooms with distances of less than 75 feet (m). Allowing test firing of Ihuru rifles.

In accordance with another feature of the invention, target aiming of a rifle is provided by using an entrance opening of a passageway structure. A plurality of pieces that are provided to move in the transverse longitudinal direction and are formed on the surface facing the test firing platform. This is facilitated by the construction of a band with a target moiety of . 1! suitable electric motors and similar Appropriate movement of the band, which can be operated manually or remotely with the aid of a Allow the patient to select and place the target area in front of the mouth.

Furthermore, the bullet collector according to the present invention is constructed of suitable material and can be mounted on a horizontal surface. 30.06N when the upper and lower deflection plates are oriented at an appropriate angle of inclination. High-energy ammunition such as ATO military bullets, 600-grain Elm Hunt bullets, and similar I can withstand it. As a result, wear and tear on bullet collection equipment, management conditions, The need for periodic replacement of parts of the bullet collection device (especially the impact plates above and below the passage and the deceleration chamber) circumferential partition walls) and associated costs are not completely eliminated, but are greatly reduced.

-For example, a bullet collection bag designed for use with high-powered firearms! The structure shown in , an angle of inclination of about 7° with respect to the horizontal plane (angle of inclination of at least the first plate below the passageway); , the beginning of the circumferential wall portion of the reduction chamber larger than approximately 71.1 cn (28 inches). The curvature radius of the part is used, and the slope part and the deceleration chamber wall in the circumferential direction are 0.95 cm. ~1.9c+* (3/8 inch ~ 3/4 inch) thick high tensile steel plate (70,0O Ops i (minimum), and the thick steel plate is used for small arms military bullets and 600-grain Elm Hunt. It has a long life and is suitable for test firing bullets. Used in the bullet collection device of this invention This type of specially designed steel plate, which is found to be well suited for Bullet collection device that covers the 0 passage and deceleration chamber commercially available as "relO" and "Trilo" The side walls of the base are constructed of 0.47 cm (3/16 inch) thick steel plate. Like this The bullet collection device (i-1) was tested to confirm that there was no perforation, destruction, or damage to the contact surface. The continuous use of bullet collectors for long periods of time has not been seen in the past.

Another advantage derived from the bullet catcher of this invention is that the liquid lubricant drain device is Because the liquid lubricant flows through a substantially closed self-contained device when , no other management is required other than periodic replacement of liquid lubricant that has evaporated over time. There is no such thing. In this regard, the liquid lubricant circulation device of the bullet collector is Another advantage is that it prevents the dissipation of lead debris into the surrounding environment. Therefore, the bullet The circumferential direction of the deceleration chamber that first meets the collision plate and then meets the deceleration chamber when fired into the concentrator. Lead debris generated in the path of travel of the bullet along the metal surface with the opposite wall is inevitably avoided. contained in the liquid lubricant injected from the injection nozzle without risk of leakage outside the equipment. It is carried along and flows over the wall of the deceleration chamber, and is discharged from the top of the plate below the passage. follow As a result, the lead debris is swept into the collection container by the liquid lubricant and settles into the liquid lubricant. and collect at the bottom of the collection container.

Liquid lubricant from the passage is thus extracted from the collection container by the circulation pump. Since the same amount of lead debris that accumulates at the bottom of the collection container continues to enter the collection container, the lead debris that accumulates at the bottom of the collection container is The liquid lubricant remains in the liquid lubricant part in the collection container, so it does not leak from the collection container to the surrounding atmosphere. On the other hand, enough lead debris has accumulated in the collection container that this Do something appropriate to reuse the lead scraps, for example to make bullets. Occasionally, the circulation piping may be removed from the collection container and the collection container filled with lead debris. Easy to remove and replace with another collection container to remove accumulated lead debris from liquid lubricants. Emissions are carried out under appropriate anti-fouling precautions. Traditional general for reuse Lead scrap recovery offers economic advantages not achieved by known bullet collectors. The above and other objects, features and advantages of the invention will be apparent from the following details when read in conjunction with the accompanying drawings. It will be more clearly understood from the detailed explanation.

Diagram of this invention In the embodiment shown, plates 13a and 13b are arranged at respective angles α with respect to the horizontal. and β in opposite directions, from the front end region 10a of the bullet catcher to the rear end region. 10b, i.e. in the direction of flight of the projectile, shown converging towards each other. ing. This allows plates 13a and 13b to have relatively wide inlet openings at their front ends. It has a mouth 13c and a relatively shallow throat or exit opening 13d at its rear end. A generally funnel-shaped passageway structure is formed. The inclination angle α and the plate 13a and 13b are and β depend on the type of firearm and ammunition for which the bullet collector is designed. It depends on the nature of the bullet catcher to be determined, and is approximately 15 degrees Oo to the horizon. preferably (but not necessarily) equal to each other.

The deceleration chamber 15 of the bullet collector 10 having a horizontal axis is generally connected to the passageway structure 13. side wall forming plate 1 in the rear end region 10b of the bullet collector; 1 and 12, respectively, and the circumference at which both ends are connected to plates 11 and 12. The wall 25 in the illustrated embodiment of the zero bullet collector formed between the boundary wall 25 is The long section of the lower plate 13b of the passageway structure, i.e. the continuation, and is generally threaded. It has a spiral shape.

Essentially, the chamber wall 25 can be considered to have three distinct parts: Ru: (i)! substantially the same as that of the lower plate 13b, as first shown at 25a'. at an angle of inclination to the horizontal, then arced upwards relative to it as shown at 25a'' (i i) first upwardly as shown at 25b' and then downwardly as shown at 25b''; An intermediate portion 25 extending in a generally forward arc of the ntm structure from the first portion 25a. b; and (iii) as shown in 25c', the upper plate 13a of the passage structure and the substantial from intermediate portion 25b downwardly and generally rearwardly of the passageway structure in coplanar relation. A terminal portion 25c extending in an arc shape, this terminal portion 25c is adjacent to the lower plate 13b. of the first part of the circumferential boundary wall 25 and from said region 25a'. , from about 3.8 cm (about 1.5 inches) to about 7.6 cm (about 3 inches), That is, the gap is at least the same as the height of the throat 13d of the passage structure 13. It has an end edge 25c''.

In this connection, what is particularly important is the nature of the bullet collector and the use of the bullet collector. Depending on the type of firearm and ammunition for which it is designed, the circumferential boundary wall 2 of the deceleration chamber 15 5 shall have a radius of curvature less than a suitable predetermined minimum size. It is true. The minimum size of the radius of curvature in each case is indicated by the arrow X in Figure 1. -1, X-2 and X-3, projectile B prior to its contact. from the previous trajectory to a curved trajectory that actually reverses its initial flight direction, compared to To enable the circumferential plate to act as a deflection plate for gently turning the target, It is empirically determined to be appropriate for the circumferential wall of each deceleration chamber. Therefore , as mentioned above, for example on bullet collectors designed for use only with air guns. In this case, the radius of curvature may be correctly small, but it is approximately 15.25 cm (6 inches). should not be smaller than the 1.220 inch rifle ( a, 22 longrifle) is not very powerful, but it is used with somewhat powerful firearms. In bullet collectors designed for use, the radius of curvature is approximately 20.3 cm. (8 inches), while the other 1.220 ng rifle but more powerful than 1.44 Magnum (a, 44 MaHnum) Bullet traps designed for use with non-standard handguns. For concentrators, the radius of curvature is approximately 22.9 cm (9 inches) or 25.4 cm (10 inches) 0 For example, high power lamps more powerful than the 1.44 magnum, such as rifles and shotguns or shotguns. In bullet collectors designed for use with firearms, one radius of curvature is 71 ．． It should not be smaller than IC (28 inches), of course any given The radius of curvature of some regions of the wall 25 of the reduced speed reduction chamber It will be appreciated that the radius of curvature may be somewhat larger than the radius of curvature or more than one radius of curvature. However, in any given case the deviation of the radius of curvature from the stated minimum value It is not expected that the difference will be greater than about 10% to 15%.

Designed for use with lead bullets, ammunition that tends to produce lead debris In any bullet catcher made of On the other hand, spray of white water lubricant (white water lubricant) spray nozzle means 16 (see FIGS. 3) is a conduit or pipe firmly attached in the region of one end in the side wall 11. 26, the pipe 26 extending substantially parallel to the horizontal axis of the chamber. Extends almost the entire length. Generally at the level of the conduit 26 the bullet collector An opening 28 is provided in the side wall 12 to provide access and access to the conduit for cleaning, repair, etc. Access to the interior of chamber 15 is permitted. The opening 28 is usually in a door or cover plate 29. More closed and sealed. The conduit 26 includes a a series of orifices facing the first part 25a of the circumferential boundary wall of the chamber. A nozzle 26b is provided. The exact positioning of the nozzle must not be rigid. However, somewhere in the area between the 3 o'clock and 5 o'clock positions, for example as shown diagrammatically in FIG. In the area between the 3 o'clock and 4 o'clock positions, the flow of liquid lubricant 27 is directed to the first wall section 25. It is preferable that they are arranged so as to face toward a.

The liquid lubricant is initially contained in a collection container 17 from where it is transported via piping 18. is supplied to conduit 26. The pipe 18 is connected to the top of the collection container 17 by a fit 18a. A pump connected to the collection container 17 in the area of the is connected to P. A collection container, for example a steel door in the illustrated embodiment of the invention. The ram is located under the front end region 13b° of the lower plate 13b of the channel structure 13, in the ejection shank. The discharge chute 3o is located at the bottom of the bullet collection device. Bottom outlet opening 31a (first (Fig. 2). The groove 31 is connected to the side wall 11 of the bullet collector at both ends thereof. 12 and at its upper edge to the underside of plate 13b, thus It has an intake opening 31b at the top and a 5cm (2 inch) 1) located directly below the slot-shaped opening 32 with a width of approximately In this case, the collection container is located within the boundaries of the bullet collector and between the legs 23.23a (not shown). and may be positioned immediately below the lower plate 13b; in either case, A removable sieve or strainer member 33 is preferably provided in the upper region of the collection container. or located somewhat below the lip of the top thereof, and the openings in the strainer member are located above the openings. Large enough to allow liquid and lead debris to pass through the bullet, Small enough to hold large bullet fragments, shells and packaging onto it.

In the illustrated embodiment of the bullet collector, the target positioning means 14 are connected to a pair of upper arms 3. 6 and a pair of lower arms 37, which arms may be welded, riveted or Permanently, such as by tightening or other forms of connection, or by screws or nuts. and bolts (not shown) that are removable by suitable fasteners such as bolts (not shown). It is secured to the external surfaces of side wall plates 11 and 12 in any suitable manner. 2 Two pairs of arms rotatably support both ends of each roll 38 and 39. A journal or bearing means (not shown) is provided for supporting the roll 3. Between 8 and 39 is a band or strip of sheet or thin material (e.g. paper). 40 is extended. The band is wound around the roll with both ends connected to the roll. and on its surface facing the shooter away from the bullet collector in the area between the rolls. has a number of target images 40a (only one shown in FIG. 2). It is provided. One of the rolls 38 and 39 is rotated. A drive means (not shown) is provided for moving the new target image through. For the purpose of moving the band to a position in front of the entrance opening 13c of the road structure tree 13, the band is moved to the idler rod. from the roll and winding onto the drive roll. rotate the drive roll For example, the drive means for advancing the band may include a clamp connected to the axle of the roll. It may also be manually operable, such as a roll handle. connected to an axle (with or without suitable gearing) and energized by the shooter. 0Alternatives may be remotely operable such as electric motors adapted to Of course, for example with the help of a stand or with the upper passage board 1 3a or by some other method (not shown), at a location in front of the entrance opening. Support plates or panels for target images may be arranged individually.

After the projectile or bullet B collides with the plate 13b at the bottom of the passage structure 13, it is received. The possible changes in flight path X are diagrammatically shown in FIG. The first flight path X is actually Assuming that the surface is horizontal, when the projectile hits plate 13b at point A-1, , as shown by the dashed line It is deflected from the lower plate 13b at a large angle. Therefore, β is 7°, 12° or 1 5 degrees, then the inclination angle of orbit X' with respect to the horizon is approximately 1 degree more, i.e. approximately 8°, 13° or 16°, which allows the projectile to never touches the upper plate L3a, but instead passes directly through the passageway throat 13d. 0th order, the projectile reaches the extreme end of the circumferential boundary wall 25 of the deceleration chamber 15 at point A-2. The collision occurs in a region 25a'' of the first portion 25a that gradually slopes upward.

Both of these collisions are thus at relatively small angles, and the plates 13a/ 13b and the first part of the chamber wall 25 is virtually at a minimum risk of being damaged or destroyed. be made small. Of course, even if the projectile comes into contact with the upper plate 13a, the trajectory The same result would be achieved, except that it would be bent downwardly from plate 13a. Dew.

As mentioned above, in the best presently contemplated mode of practicing this invention, the passageway The upper and lower plates 13a and 13b of the structure 13 are at an angle of about 15° to the horizontal. be tilted at each angle. However, as pointed out earlier, the horizon line The angle of inclination of one or both of the plates 13a and 13b relative to the It should be understood that it is also within the contemplation of this invention that the same may be used.

For example, the passage structure 13 can be formed at inclination angles α and β as small as about 1° or 2°. Orienting the upper and lower plates at a 15° angle will help avoid shattering the projectile during impact. or at an angle of 7°. In fact, a tilt of 0° oblique angle (at this oblique angle, plates 13a and 13b are, strictly speaking, oblique) (rather than parallel to the horizon and to each other) the fragmentation of the projectile This is even better from the standpoint of avoiding A properly aimed projectile that has been properly aimed at will not touch either the upper or lower plates 13b and 13b. The possibility of going straight through the passage structure into the deceleration chamber without contact This is because it is large.

Using this low angle orientation of the impingement or deflection plates at the top and bottom of the passage structure Despite this, actual considerations also point out the opposite.

Initially, the desired height of the throat or outlet opening 13d of the passageway structure 13 is approximately 3.8 cm (1.5 inches) to at most about 7.6 ca+ (3 inches), preferably It must be noted that up to approximately 5.1 cm (2 inches) As a result, the arrangement of plates 13a and 13b at an angle of inclination of 2° or less The direction provides an inlet opening to the passageway structure that is approximately as small as the outlet opening. Therefore, the length of the passageway structure is such that the inlet opening 13c The diameter is 91.4 cm (36 inches) from the exit opening 13d, and the throat is 5.1 cm. m (height of 2 inches), the slope is 1° or 2° with respect to the horizontal line. Positioning the upper and lower passage plates 13a and 13b at an oblique angle is approximately 8 ．． 3c+s (3,25 inches) or approximately 11.4cm (4,5 inches) high This provides a very small entry aperture for firearm aiming errors. Such a small inlet opening 13c in a one-passage structure would leave only a small margin. of a firearm fired almost immediately adjacent to or inserted into said opening 13c. Of course, by positioning the muzzle, the risk of a bullet missing the aperture is minimized. , perhaps even completely removing it, however, for the purpose of inspecting the firearm. Or positioning a firearm in this manner for the purpose of firing a functional fire is quite Although good, it may not be acceptable behavior for the purpose of target testing. , target inspection is the process by which a projectile enters the flight path before reaching the target location in front of the bullet collector. To enable the projectile to stabilize as it moves, a bullet collector! example from For example, it must be at a considerable distance of at least about 22.9 meters (75 feet). It is what you need.

Therefore, at an angle of inclination of up to 15° with respect to the horizontal, the upper and lower plates 1 of the passage structure It is these considerations that make it preferable to orient 3a and 13b.

0.91 m (3 ft) long terminating in a 5.1 cm (2 in) high throat At an angle of inclination of 12° or 15° of the two plates of the passageway structure 13, the inlet opening The mouth is hollow, 43.9 cm (17.3 inches) or 54.1 cm (21 , 3 inches) in height. For the same reason, 3.05 m (10 feet) or 3.66... (12 feet) long, upper and lower two of the passage structure 13. At a 7° angle of inclination of the plate, the height of the inlet opening is approximately 76.2 cm (30 in. h) or 91.4 cm (36 inches), resulting in the firearm being targeted. The risk of missing the passage at all is completely eliminated, even when

From the above, the term "inclination angle" used in this application refers to the angle of inclination with respect to the horizontal line. Specify any orientation of plates 13a and 13b at an angle within 15 degrees from Oo. is intended and should be construed as specifying.

Therefore, the projectile B is fired at the bullet collecting device (bullet trap) 10, and the passage boundary plate , for example, the lower plate 13b of the passage structure 13, the projectile Understand that only a small portion of its energy will be lost by the first collision of The projectile then continues virtually unhindered to the deceleration chamber, However, it is made of metal and equipped with a liquid lubricant spray and circulation system. In the bullet collection device according to the invention, the presence of lubricant in the passage and the deceleration chamber , significantly reducing the metal-to-metal frictional contact between the projectile and the plates it contacts. It should be noted that although it works to reduce the effect of friction, it does not completely eliminate the effect of friction. be. Therefore, if the projectile is lead (perhaps 90% of all bullets ejected as powder) If a bullet is made from The wax and lead debris would create a health and environmental hazard if it leaked into the atmosphere. However, at the same time as its formation, lead debris is sucked into the flowing liquid lubricant. The lead debris is entrained thereby and moves towards the collection container 17. Furthermore, since the lubricant flows into the collection container 17, the liquid cannot leak out. Lead debris, which is much heavier than the body, settles almost immediately to the bottom of the container, as shown in Figure 34. As in, it accumulates there.

Apart from the ecological advantages mentioned above, this behavior has two direct highly advantageous consequences. do. One is of operational importance, in which the accumulation in the collection container 17 The amount of liquid located on top of the lead debris 34 is effectively self-cleaning and Liquid is then withdrawn from the upper region of the collection container and passed through line 18 and pump P. When recycled to the spray nozzle means 16, it does not contain any lead debris; Blocking of the pump and orifice or nozzle 26b is avoided. The other is sutra of economic importance, in which the system automatically protects the environment as well as Providing waste utilization of lead garbage as processing material. Therefore, enough lead trash is collected. When a buildup occurs in a container and it becomes appropriate to remove it, the pump de-energizes. the fitting or valve cock 18a is closed, and the piping is removed from it. and preferably the strainer member and its accumulated debris are removed. Once the collection container has been Under appropriate environmental protection measures, lead debris may be separated from the liquid remaining in the container. , and can be processed for reuse in manufacturing bullets.

In any bullet collector according to this invention made from metal, lead debris is removed from the bullet. Confining the interior of the collection device and the flow path of the liquid lubricant is provided by various plates 11 ．． 12.13a and 13b/25 are ensured by welding them together. It is worth mentioning this at this point. Furthermore, this According to welding, it works to make the structure of the bullet collector rigid and strong. Apart from that, the structure also has a liquid-tight seal at all joints between the plates. Provided to. On the other hand, steel (with lead) made of plastic etc. and fired with an air gun (No) BB’s or any bullet collection device designed for use with bullets. As mentioned above, it is important to have a liquid lubricant spray and circulation system in place. may be exempted because of the self-lubricating nature of the material from which the bullet catcher is made. This is because frictional drag is minimized by its nature. However, even if The bullet collector is preferably constructed with complete sealing at all junction points. Indeed, such a seal can be used to form the bullet catcher as a subsequent casting. or with the aid of heat, sticky substances or other adhesives This is achieved by properly gluing or fusing various plates, thus This means that it will work to solidify and strengthen the structure of the bullet collection device. Avoid any BB's or bullets escaping away and being fired into the bullet collector It also helps.

Now, returning to projectile B (be it a bullet or BB) entering the bullet collection device. , the remains of the projectile after it passes through the throat or exit opening 13d of the passageway structure. The stored energy dissipates when the projectile leaves the deceleration chamber 15 for a week. fired used The body eventually falls onto the terminal portion 25c of the chamber wall 25, and its end edge 25c'' Beyond, the first part 25a of the wall 25 adjacent to the lower plate 13b of the passage structure 13 fall on top of From there, the projectile passes through throat 13d and passes through plate 13 as shown in B-4. b and roll toward its release area as shown by arrow Y in Figure 1. Or glide. This movement is caused to an extent by the force of gravity and If body lubricant is sprinkled on the first part 25a of the chamber wall (therefore the bullet The collector may legitimately be referred to as a "wet" bullet collector), with lubricant along the walls of the chamber. downwardly, therefore through the throat 13d and along the lower plate 13b of the passage structure 13. and is assisted by the liquid as it flows toward the front of the bullet catcher.

In the case of a "wet" bullet catcher, the liquid eventually passes through the aperture 32. 31 and thus fall into the collection container 17. The transverse stepped portion or plate 35 is At the downstream edge of the opening 32 there is provided a top of the end portion 13b' of the plate 13b. liquids and projectiles, and any projectile fragments, shells and casings. ) is deflected down along the plate 13b into the opening 32 and the end portion 13b of the plate constitute a barrier to prohibit passage beyond . On the other hand, "dry" bullets In the case of a collector, the BB or bullet passes through the opening 32 in the lower plate 13b; allowed to descend into a collection container positioned below, but alternatively, Providing an opening can be exempted and the BB or bullet can simply be inserted into the barrier plate or is stopped by a stepped portion 35.

Add white water or white water lubricant to a "wet" bullet collector. If water (1 utility) is used, it can be used to lubricate and remove Apart from its functionality, it also has the advantage of adding soundproofing to the bullet collector. One advantage, in fact, is that the noise level of a bullet traveling through a bullet collector is When there is liquid, it is smaller than when there is no liquid, about 10 db. The reason for this is that the white oak is used as the wall for the passage structure. a and 13b and the impact of the bullet against the circumferential boundary wall 25 of the deceleration chamber 15; This is because it absorbs vibrations and harmonics resulting from the bullet's motion along the

From what has been explained so far, the spatial requirements for the bullet collection device according to the present invention are It will be clear that the problem is relatively small; furthermore, any such bullet collection device The weight is less than 226.8Kg (500 bond) and the plastic In the case of a bullet collector made of 0 bond). Therefore, the bullet collection device can be Can be easily moved to another location, yet when in use Completely stable. Selection for any given bullet catcher according to this invention The specific “ramp angle” (angle of inclination of passage plates 13a and 13b) determined by Generally depends on the type, i.e. the weight and velocity of the projectile to be fired into the bullet collector. It should also be noted that there are Therefore, an angle of 15° is It is acceptable for BB or bullets fired from a gun, but 12゜ or is a smaller angle (lower to about 7°) than that of a powder-ejected bullet (po wder-discharge bullets) cormorant.
