Abstract:
The present invention discloses a magazine loader device ( 1 ) for firearms which consists of a lower section ( 1 A) and upper section ( 1 B). The upper section ( 1 B) receives individual vertically-oriented cartridges from the hopper ( 61 ), turns them in the right direction using a rotating mechanism ( 32, 33, 34 , and  35 ), which is the essential part of the upper section ( 1 B), and pushes them towards the lower section ( 1 A). The lower section ( 1 A) pushes the correctly facing cartridges (N) into the magazine ( 20 ) which is inserted into the hollow grip ( 21 B,  22 B) of the lower section ( 1 A). The tripping plunger ( 17 ) is an essential element of the lower section ( 1 A) which in cooperation with the controlling curve ( 13 E) pushes the cartridge pusher ( 20 A) or the preceding cartridge down by a characterized in that, enables the next cartridge to enter the magazine, and timely retracts, so the cartridge (N) can be pushed into the magazine until the end. The lower section ( 1 A) of the device can also be used independently.

Description:
TECHNICAL FIELD 
     The subject of invention is a magazine loader device and it relates to firearms, particularly to the field of devices for loading magazines of firearms. 
     DEFINITION OF TERMS USED 
     According to the present invention the user holds the device by the hollow grip in which a magazine has been placed as he would hold a pistol. 
     The description of the present invention includes the following directions (left, right, top, bottom, front and rear) viewing from the perspective of the device user. The “front part of the cartridge” means the bullet side of the cartridge; on the other hand the “rear part of the cartridge” means the end with the blind side of the cartridge sleeve. 
     DESCRIPTION OF THE TECHNICAL PROBLEM 
     As shown in  FIG. 3A , the magazine  20  consists of a substantially vertical box-shaped housing which in its interior contains a normal helical coil spring which extends upwards from the base of the housing, at the top of which is a cartridge holder or the so-called magazine cartridge pusher  20 A which engages the cartridge that was inserted into the magazine first. 
     The magazine housing is encased at the lower end and open at the top end. The distance between the longer vertical planes of the housing narrows towards the top of said housing of magazine  20 . When the magazine is empty, the pusher  20 A remains at the height where said narrowing of the housing  20 B starts. 
     Thus, the feeding compartment is obtained in the upper front end of the magazine housing, into which the first cartridge can be placed on the pusher from the upper side in such a way that a smaller part of the cartridge protrudes through the front narrower plane of the housing, where it is pushed downwards on the pusher and back, so the cartridge slides onto the pusher  20 A and with its rear side rests on the rear narrower side of the housing. Thus, the first cartridge is secured below by the pusher, on the top it is secured with the narrow end of the housing, while the rear area is restricted by the rear narrow side of the housing. 
     During loading of each cartridge into the magazine, the pusher moves a notch downwards. In the next and each subsequent step a cartridge is inserted onto a previous cartridge, pushing it further downward, whereby all previously loaded cartridges and the pusher  20 A move a notch down. The cartridge is then pushed back to slide onto the previous cartridge to the back narrow surface of the housing. 
     The manual loading process is a time consuming operation which also requires certain skills and strength of the person loading the magazine. 
     STATE OF THE ART 
     Only magazine loader accessories are known in the art (e.g. type “uplula”, “HKS”, “XD magazine Loader”), which operate on the principle of “helping” pushing the magazine cartridge pusher or the top cartridge. All accessories of this type require inserting cartridges manually, one by one, and then lifting such accessory and pushing a cartridge into the magazine manually, by hand. 
     A device of such type is also described in published patent application filed Jan. 13, 2010 in the U.S. application Ser. No. 12/686,629 entitled title “Rapid pistol magazine loader”, of inventor Edward Steele Meinel, Reston, US. 
     The invention described in said application suggests insertion of cartridges manual or using specially adapted cartridge packaging. Drive of this device is not shown in patent application, however the proposed operating mode indicates that the device is manually operated in both directions, and elements are guided through the side slots, with variable direction. The description of the device is unclear, and therefore, its operation is questionable, especially regarding synchronization of movements of individual elements, whereby loading of cartridges into the magazine should be enabled. 
     The disadvantage of above-described solution according to the state of the art lies in the fact, that it is necessary to push a cartridge into the magazine by hand, which is strenuous for the person doing this, or special packaging where cartridges have been already sorted, is required. 
     BRIEF DESCRIPTION OF THE INVENTION 
     As described below, the present invention solves the technical problem by introducing a device  1  ( FIG. 1 ), which allows easy loading of cartridges into the magazine, wherein the device according to the present invention, comprises also a sorting section, sorting the cartridges which come from a hopper, turning each cartridge in the right direction and feeds it to the lower section of the device, facing in the right direction. 
     The device  1  according to the present invention consists of two basic sections, namely a lower section  1 A and an upper section  1 B. The lower section  1 A represents housing with an exchangeable grip, movable lock and tripping plunger. Individual cartridges, facing the right direction, are manually inserted into the housing, where in the return stroke latch pushes them into the magazine, inserted and secured in the hollow part of the grip. 
     The lower section  1 A of the device  1  can be used independently or in combination with the upper section  1 B of the device  1 . 
     The upper section  1 B consists of a housing which includes a rotating mechanism for turning the cartridges, above which a hopper is provided, into which multiple cartridges are freely dropped and from which individual cartridges fall into the rotating mechanism in a vertical position. Individual cartridge always drops into the rotating mechanism vertically and may be oriented with the bullet facing down or with the sleeve facing down. The rotating mechanism detects the orientation of the cartridge, and depending on its orientation, it rotates it, so the cartridge falls always with the bullet facing down into the inlet opening of the lower section of the device.

     DETAILED DESCRIPTION OF THE INVENTION 
       FIGS. 2, 3A and 3B  show the lower section  1 A of the device  1  according to the present invention. The lower section  1 A consists of the right part of the housing  11 , the left part of the housing  12 , latch  13  and pull handle  14 . 
     The right part of the housing  11  consists of the top part  21 A and the lower part  21 B, analogously the left part of the housing  12  consists of the top part  22 A and the lower part  22 B, respectively. The said top parts  21 A,  22 A and lower parts  21 B,  22 B are coupled together pairwise in a detachable manner so that the lower parts  21 B and  22 B can be replaced, if necessary. Such detachable coupling may include appropriate sliding guides with lock bolt, bolted connection, etc. 
     The said lower parts  21 B,  22 B in assembled state form a hollow grip for insertion of magazine  20  to be charged; therefore the possibility of replacement is necessary so the device can be used with different magazines. 
     The said pull handle  14  and latch  13  are detachably coupled by means of a dovetail  13 A,  14 A or similar coupling and secured with a screw or spring pin  14 B. The latch  13  has on the lower portion upper guides  13 B, running alongside the entire latch  13 , and lower guides  13 C running essentially alongside the front quarter of the latch  13 . 
     During operation of the device  1  the upper guides  13 B of the latch  13  slide on corresponding guides  12 A on the outer side of the left part of the housing  12 , and  11 A on the outer side of the right part of the housing  11 , while the lower guides  13 C slide on the corresponding guides  12 B on the internal side of the left side of the housing  12 , and  11 B on the internal side of the right part of the housing  11 . 
     Under the upper guides  13 A and above the lower guides  13 C of the latch  13 , parallel to said guides, runs an opening  13 F for receiving a guiding rod  15  of a spring  15 A, here the guiding rod is fixed into the holder  16 . Behind the said holder  16  the tripping plunger  17  is positioned, detailed in  FIG. 4 , consisting of the lower portion  17 A and the upper portion  17 B, wheel  17 C that rotates freely on a pin  17 E and the spring  17 D. The said elements of tripping plunger  17  are joined by two connecting pins  17 E and  17 F, where the pin  17 E connects the upper portion of the tripping plunger  17 B and the wheel, while the pin  17 F connects the upper and lower portion of the tripping plunger  17 A,  17 B and the spring  17 D. 
     The tripping plunger slides on corresponding vertical guides  12 C of the left part of the housing and  11 C of the right part of the housing, while the wheel  17 C runs along the controlling curve  13 E shown in  FIGS. 5A to 5G . 
     In the assembled state, both parts  17 A and  17 B are mutually movable around the axis of the pin  17 F only when the upper part  17 B rotates forward by approximately 90°, while backward rotation is disabled with square formed upper rear part of the lower end  17 A of the tripping plunger  17 . 
     In order to provide return vertical motion of the tripping plunger  17 , the device contains a spring  18 A which is with pin  18  engaged in the grooves of the housing  11 D and  12 D ( FIG. 3A ). The spring  18 A pushes with its lover arm to the lover area of the housing, while the upper arm is located in the cavity of the tripping plunger  17 , under the pin  17 F, so the spring  18 A is preloaded. When tripping plunger  17  travels downwards, the pin  17 F tensions the spring  18 A. 
     As shown in  FIGS. 3A and 3B , the most part of the lock  13 , approximately along the last three quarters, is hollow. The interior of the top wall of lock  13  has a double-hump controlling curve  13 E, by means of which it controls the tripping plunger  17  with a wheel  17 B, so the plunder  17  periodically travels in vertical direction along the corresponding vertical guides of left part of the housing  12 C and right part of the housing  11 C. 
     The said left hand side of the housing  12  of the lower section  1 A of the device  1  has a side opening  12 E in the upper central part, through which a cartridge is inserted into the device, either manually or as described hereunder, by means of the upper section  1 B of the device  1 . 
     The said left side of the housing  12  has longitudal outer guides  12 F, positioned on its outer side, where the upper section  1 B of the device  1  is fixed, as described below, while the left side of latch  13  has an opening  13 D for receiving a pin  13 D 1  ( FIG. 2 ) running through the slot  34 B of the outer fork  34  of the upper section  1 B ( FIG. 9B ), whereby it provides a synchronized drive of the upper section  1 B of the device  1 . 
     Description of Operation of the Lower Section 
     Operation of the lower section  1 A of the device  1 , according to the present invention is demonstrated by individual steps in  FIGS. 3A to 3G , namely in longitudinal section. 
       FIG. 5A  shows the lower section  1 A of the device  1  in a starting position. The spring  15 A pushes the latch  13  in the most front position. An empty magazine  20  is inserted into the cavity of the grip  21 B,  22 B from the bottom side, fixed and secured against falling out by means of a latching member  19 . The tripping plunger  17  is in the upper position pushed by the spring  18 A. A cartridge N, facing correctly is inserted through the opening  12 E. The user holds the lower part  1 A with one hand and with the other pulls the latch  13  back, towards him, by means of the pull handle  14 . 
     In the second step ( FIG. 5B ), the latch is moved back, to such a distance that the controlling curve  13 E pushes the tripping plunger  17  by means of the wheel  17 C in its lowest position so that the bottom part of the tripping plunger  17 A pushes the cartridge pusher  20 A downwards, while at the same time latch  13  with guides  13 C reaches cartridge N. The spring  18 A is in the bottom, most tense position. 
     In the third step ( FIG. 5C ), the latch  13  is moved back to such a distance to move the cartridge N for about a third of its length into the magazine  20 , the tripping plunger  17  travels by means of wheel  17 C along the flat part of the curve  13 E and does not move vertically. 
     In the fourth step ( FIG. 5D ), the latch  13  is moved back to such a distance that the spring  18 A raises the tripping plunger  17  in the uppermost position, and the latch  13 , with the rear side of guides  13 C, pushes cartridge N into the magazine  20 . The cartridge N travels onto the pusher  20 A in the upper part being clamped by the curved upper part of the magazine  20 , so that the pusher  20 A cannot push it upwards. 
     In the fifth step ( FIG. 5E ), the latch  13  is moved to its rearmost position, while the tripping plunger  17  travels by means of wheel  17 C along a straight section of the curve  13 E and remains in the uppermost position; the cartridge N is pushed into the magazine to the end. The spring  15 A is in its most tensed position. 
     Now the user releases the force pulling the latch  13  by means of pull handle  14  toward the body, and the spring  15 A in a return stroke pushes the latch  13  towards the starting position. 
     The  FIG. 5F  shows the first step of the return stroke towards the starting position. The tripping plunger  17  withdraws with its upper portion  17 B from the vertical part of the curve  13 E by pivoting forward around the axis of the pin  17 F by approximately 90°, and consequently, the lower part  17 A of the tripping plunger  17  does not move downward, whereby the entire tripping plunger  17  also pushes the spring  18 A upwards. 
     The  FIG. 5G  shows the lower section of the device  1 A in a starting position. The spring  17 A returns the upper part of the tripping plunger in a straight position. The next cartridge N 1  is inserted into the device. 
     Repeating the above-described cycle, the plunger  17  pushes the cartridge deeper into the magazine, thus making room for the next cartridge N 1 . The user repeats the cycle until the magazine  20  has been loaded to the desired extent, then withdraws it from the cavity of the handle  21 B,  22 B by releasing the latching member  19  and inserts the next one. 
     Upper Section of the Device 
       FIGS. 6, 7, 8A and 8B  show the upper section  1 B of the device  1  according to the present invention, consisting of a housing  31  comprised of the right part of the housing  41  and the left part of the housing  51  which are joined by bolts (not shown). The right part of the housing  41  has on its right-hand side a sliding rail  41 B that fits to the guides  12 F of the left part of the housing  12  of the lower section  1 A of the device  1  described above. The opening  81  on the sliding rail  41 B and the opening  82  in the left part of the housing  12  overlap in order to receive a connecting pin (not shown), which interconnects the lower part  1 A and the upper part  1 B of the device  1 . 
     The said right part of the housing  41  has on the lower portion a shaped opening  41 C extending through the part of the housing  41  and through the guides  41 B through which facing correctly cartridges enter from the upper section  1 B to the bottom section  1 A of the device  1 . 
     The said right and left parts of the housing  41 ,  51  have opposite and elongated recessed areas  41 D,  51 D which have in the central part two slots  41 A,  51 A where a freely rotating wheel  35  is mounted. The lower fork  32  which is clamped in the corresponding recesses  32 A in both portions of the housing  41 ,  51  is positioned under the rotating wheel  35 . 
     The housing  31  also contains a rotating wheel  35  and rear fork  33  which is by means of two pins  34 A rigidly connected with the outside part of the fork  34  that is located on the outer right side of the right part of the housing  41  where the pins pass through the slot  41 E. On the outer side of the right part of the housing  41 , a spring  41 G is positioned in the spring receiving opening  41 F. 
     For a forced correct positioning of the rotating wheel  35  in the rear position ( FIG. 10A, 11A ) two conical plates  41 J (only the right one is shown) or similar elements which are latched in the corresponding recesses  41 H,  51 H are located in the housing  31 . A revision opening  51 L is provided in the left side of the housing  51 , where the said opening  51 L is covered with a transparent covering element  51 M. 
     The rotating wheel  35  consists of two discs  35 A which are located in parallel planes and interconnected by four pins  35 B, uniformly distributed over the outer edges of said discs  35 A, as shown in  FIG. 9A . 
     From the outer side of each disc, a protruding pin  35 C is located, fitting into the corresponding slot  41 A,  51 A. The pin  35 C located on the outer side of the right part of the housing  41  protrudes from the housing  41  by a distance not greater than the thickness of the outer fork  34 , and pin  35 C on the outer side of the left part of the housing  51  protrudes from the housing  31  by the same distance or it is aligned with the housing. 
     The depth if said recesses  41 D and  51 D of the left part  51  and right part  41  of the housing  31  is equivalent to the sum of the thickness of discs  35 A, thickness of plates  41 J and a clearance between 0.5 mm and 1 mm, thereby allowing free rotation of rotating wheel  35 . The distance between the discs  35 A is approximately the same as the distance between two adjacent pins  35 B and corresponds to the largest diameter of the cartridge N, increased by the necessary clearance which in dependence on the largest diameter of the cartridge ranges between 0.5 mm and 2 mm, preferably between 1 mm and 1.5 mm. 
     The rear fork  33  is shown in  FIG. 9B  and contains a bottom, horizontal arm  33 A, the vertical portion  33 B with a protruding cam surface  33 D and the upper horizontal arm  33 C with a downwardly protruding cam surface  33 E and two openings  33 F for connection with the outer part of the fork  34 . 
       FIG. 9B  also shows the outer part of the fork  34  consisting of a flat portion which has two openings  34 F in the upper rear part with inserted pins  34 A for connecting to the rear fork  33 . There is a slot  34 B in the central part of the outer fork portion  34  through which extends a pin  13 D 1 , where the slot  34 B runs practically along the entire length of the outer fork portion  34 , and in the front part of fork  34  there is a downward protruding lever  34 C. 
     In the assembled state, the housing  31  has a vertical opening  31 A in the upper part, with essentially a round cross section, through which individual cartridges enter into the housing  31 . 
     As shown in  FIG. 7 , a hopper  61  is attached to the slider  41 K,  51 K of the circumference of said inlet opening  31 A, where the hopper  61  is covered with a seal  62  with a revision opening  62 A, which is preferably covered with a transparent layer, such as plexiglass or similar. 
       FIGS. 10A to 10E and 11A to 11E  schematically show the assembled device  1 , wherein the upper section  1 B is clamped to the lower section  1 A in a manner as described above. The grip  21 B,  22 B of the lower section  1 A of the device  1  is not shown. 
     Description of Device Operation 
     The cartridges are freely dropped into the hopper  61 , covered with the seal  62 . The user holds the device  1  in one hand, while at the same time, with the other hand, pulls back, i.e. towards his body, the latch  13  by means of the pull handle  14 . The pin  13 D 1  fixed in the opening  13 D of the latch  13  travels along the groove  34 B of the outer fork  34  at idle until it reaches the back wall of the groove  34 B and pulls the outer fork  34  to the rear position, consequently also moving the rear fork  33  to the rear position. The lever  34 C of the outer fork  34  also moves the pin  35 C and consequently the rotating wheel  35  to the rear position, and tensions the front arm of the spring  41 G, which protrudes from the receiver  41 F. The upper horizontal arm  33 C of the rear fork  33  is not closing the inlet opening  31 A anymore. 
     When the latch  13  is removed from the foremost position, it initially moves alone until the pin  13 D 1  reaches the rear wall of the slot  34 B of the outer fork  34 , which are through the opening  41 E rigidly coupled with the rear fork  33  by means of pins  34 A. From here onwards the latch  13 , the outer fork  34  and the rear fork  33  move together towards the rear position until they reach the point where the vertical lever  34 C of the outer fork  34  reaches the right pin  35 C of the rotating wheel  35 . From here onwards the rotating wheel  35  moves together with the above mentioned elements towards the rear position. 
     Consequently, the stroke length, i.e. the length between the front most position and rearmost position, of the latch  13  is longer than the stroke length of the outer fork  34  and outer fork  33  assembly, which is however longer than the stroke length of the rotating wheel  35 . 
     As mentioned above, the cartridge N may fall from the hopper  61  through the opening  31 A into the housing  31  of the lower section  1 B with bullet facing down or sleeve facing down. By pulling the latch  13  the hopper shakes and consequently the cartridges cannot get jammed. 
     Operation of the upper section  1 B for both possibilities is described hereunder. 
     Cartridge with Bullet Facing Down 
       FIG. 10A  shows a position where the latch is in its rearmost position, the upper horizontal arm  33 C of the rear fork  33  is withdrawn in the rearmost position, and the rotating wheel  35  is in the rearmost position, where both rear pins  35 B engage on the conical plates  41 J, whereby the rotating wheel  35  is forcibly placed in the correct position. The cartridge N falls from the hopper  61  through the opening  31 A into the housing  31  of the upper section of the device  2  with bullet facing down and stops on the lower fork  32 , in the rotating wheel  35 , between two adjacent pins  35 B. 
       FIG. 10B  shows the next step wherein the user releases the pull force on the latch  13  and the spring  15 A is pushed forward by the lock  13 , the spring  41 G moves the pin  35 C and with it the rotating wheel  35 , where the cartridge N is located, to the front most position. The upper horizontal arm  33 C of the rear fork  33  has been moved forward, whereby entry of the next cartridge N 1  into the housing  31  is made impossible. The cartridge N with the bullet facing down falls through the gap of the lower fork  32  by the length of the bullet. 
       FIG. 10C  shows the next step where the user further releases the pull force on the latch  13 . The upper horizontal arm  33 C of the rear fork  33  in this case has no role and passes over the cartridge N and the rotating wheel  35  towards front most position. The lower arm  33 A of the rear fork  33  reaches the bullet of the cartridge N. 
     As shown in  FIGS. 10D and 10E , the lower arm  33 A of the rear fork  33 , during further travel forward, pushes the cartridge N, which is located in the rotating wheel  35 , and therefore the rotating wheel  35  rotates, the protruding cam surface  33 D reaches the rotating wheel  35  and the correctly facing cartridge N, falls from the rotating wheel  35  into the opening  41 C, and through it into the opening  12 E in the lower section  1 A of the device  1 . 
     Cartridge with Bullet End Facing Down 
       FIG. 11A  shows the same position as  FIG. 10A  where the cartridge N has fallen from hopper  61  through the opening  31 A into the housing  31  of the upper section of the device  2  with the sleeve facing down. The cartridge N stops on the lower fork  32 , in the rotating wheel  35 , between two adjacent pins  35 B. 
       FIG. 11B  shows the next step wherein the user releases the pull force on the latch and the spring  15 A is pushed forward by the lock  13 , the spring  41 G moves the pin  35 C and with it the rotating wheel  35 , which holds the cartridge N, to the front most position. The upper horizontal arm  33 C of the rear fork  33  has been moved forward, whereby entry of the next cartridge N 1  into the housing  31  is prevented. The cartridge N with the sleeve facing down slides along the upper surface of lower fork  32 .  FIG. 11C  shows the next step where the user further releases the pull force on the latch  13 . The lower horizontal arm  33 A of the rear fork  33  in this case has no role and passes over the cartridge N and the rotating wheel  35  under the lower fork  32  towards the end position. 
     The upper horizontal arm  33 C of the rear fork  33  reaches the bullet of the cartridge N and the rotating wheel  35  rotates partially towards the front side of the device. During the rear fork forward motion, the protruding cam surface  33 E reaches the upper rear pin  35 B of the rotating wheel  35  rotating it for the remainder of the stroke to such an extent that the cartridge N is in a horizontal position with the bullet facing forward. 
     As shown in  FIGS. 11D and 11E , the rear fork  33  during forward travel reaches the cartridge N with the protruding cam surface  33 D pushing it forward from the rotating wheel  35  so that the rotating wheel  35  rotates by approximately 45° due to the weight of the cartridge, which facing correctly falls from the rotating wheel  35  into the opening  41 C and through it into the opening  12 E in the lower section  1 A of the device  1 . 
     The operation of the entire device is clear from the above description of operation of both sections  1 A,  1 B of the device  1 . Namely, when inserting magazine  20  in the device  1  and dropping the cartridges in the hopper  61 , in the first cycle which starts with the movement of the latch  13  to the rearmost position and finishes with the return stroke of the latch  13  in the front most position, the cartridge N travels from the hopper  61  through the opening  31 A into the rotating wheel  35  and from said rotating wheel  35  the cartridge facing correctly falls into the opening  41 C and through it into the opening  12 E in the lower section  1 A of the device  1 . 
     In the second cycle, the cartridge N, which is after the first cycle located in the opening  12 E, travels into magazine  20 , while at the same time the next cartridge falls into the upper section  1 B of the device. 
     It is therefore a simultaneous operation of both parts of the device  1  where in the second and each subsequent cycle two cartridges travel through the device. 
     The materials of the said elements of the device according to the present inventions are known in the art. Springs, pins, wheel  17 C of the plunger  17  and guide rod  15  are made from a suitable steel, parts  17 A and  17 B of the plunger  17  are made from aluminium or stainless steel, lock  13 , pull handle  14 , the housing of the lower section  11 ,  12 , the housing of the upper section  31  are made of composite materials, stainless steel, aluminium alloy and the like, hopper  61  and cover  62  are preferably made of plastic. Movable parts such as forks  32 ,  33  and  34 , plates  41 J, rotating wheel  35  are made of suitable steel which must have good sliding properties and is resistant to corrosion. Such materials are known in the art, and therefore will not be specifically described herein. 
     The device  1  according to the present invention as described above is intended for manual use and enables loading of cartridges (N) into a magazine ( 20 ) at a rate of 0.5 to 2 cartridges per second, preferably 1 cartridge per second. 
     According to the present invention the device can with minimal adjustments be reworked so that the device can be power-driven by means of a suitable unit such as an electric motor and the like, in combination with a suitable element that converts the rotational movement into translational movement (crank mechanism and eccentric cam), while it is also possible to introduce a pneumatically-driven piston unit and the like. In such case, the above said pull handle  14  should be replaced with a handle shaped so as to permit connection with the drive unit, for example by means of a pin, whereby the handle of the lower section of the device must be rigidly clamped in a suitable clamping device. 
     The device according to the present invention has been described and detailed in the attached drawings in an understandable manned and by means of concrete examples of use and operation. Various version of this device are possible, which however fall within the scope of this invention.
