Abstract
Description
- This application claims the benefit of U.S. Provisional Application No. 60/855,339, filed Oct. 30, 2006.
- A. Field of Invention
- The present invention relates generally to devices used in ammunition reloading and more particularly to a new and improved device for installing primers in ammunition cartridges.
- B. Description of Related Art
- In the reloading of used ammunition cartridges, the handling and installation of new primers into the cartridge is a most difficult and tedious operation. The usual ammunition primer is a small cup containing a substance designed to ignite in response to impact. Due to their small size they are difficult to pick up and place in the installation device with proper orientation for installation. A number of devices attempt to aid in the handling and installation of primers, including the device described in U.S. Pat. No. 4,222,305 to Lee, however that device is not readily adaptable for use with the single station reloading press currently in common usage. Most single station reloading presses are equipped with a cup and punch designed to accept a primer of the proper size and are mounted on a pivotal primer arm. A primer must be placed into the cup with proper orientation and then the arm is swung into position to prime the case. The press ram with cartridge case in the shell holder is then lowered onto the primer to seat it into the primer pocket of the cartridge case. A conventional automated system for handling primers involves the use of a tube filled with primers and means to meter a single primer into the primer cup. The requirement of the conventional system is the loading of the tube with properly oriented primers, which is time consuming and usually augmented with a primer flipper to turn all of the primer right side up. Since the primers are stacked and axially aligned within a tube, handling the loaded tube is dangerous and requires great care. A safer primer handling technique uses is a trough to transport the primers to the reloading stage while in a parallel alignment, however, it is very difficult to transfer a primer from the end of a trough into the primer arm cup since attempts to drop the primer into the cup result in the primer tipping and not cleanly entering the cup in the proper orientation for installation.
- It would therefore be desirable to provide a device for reliably and safely transporting a single primer from a supply trough to a primer loading cup while maintaining the proper primer orientation.
- The device of the present invention uses current technology to feed primers from a tray into a trough, the invention being a primer transport device at the end of the trough for loading the primer into the primer cup of a conventional reloading press. The device contains a sliding primer holding member that is movable between a primer loading position at which position a primer is allowed to enter the device from a primer supply trough and a primer insertion position at which position the primer is positioned to be moved into the primer loading cup. As part of the single operation, the sliding member precisely positions the primer over the primer cup and a plunger pushes the primer into the priming cup. The plunger operation rapidly accelerates the primer into the cup with a positive acceleration preferably greater than the acceleration of gravity so that the primer to remains in contact with the end of the plunger until the primer is within the cup. Maintaining contact between the plunger and primer during the transfer into the cup maintains the proper orientation of the primer, increasing the reliability of the process.
- The device is assembled of molded plastic parts including a lower body section, the sliding member, the plunger, and a trigger section. The sliding member is formed as a rectangular prism with a height approximately equal thickness of a primer to be installed. The lower body section comprises slot within which the sliding member travels and which restricts the sliding member travel, and a flat floor supporting the sliding member and a stop that prevents the sliding member from movement past the primer insertion position. A “V” shaped horizontal notch is formed in the sliding member and sized to receive a primer from the supply trough, when the sliding member is in the primer loading position. The body section slot includes a wall with an opening adjacent to the supply trough from which a primer will enter the empty notch by gravity feed when the sliding member in the primer loading position, at which position, the sliding member notch is adjacent to the body section slot wall opening. The device is finger operated against an opposing spring, which acts to reset the device by returning the sliding member from the primer insertion position to the primer loading position. Because the return spring is at a slight angle to the direction of travel of the sliding member, the return spring also biases the sliding member toward and against the slot wall toward the loading trough. As the sliding member moves to the primer insertion position, the wall contains the primer within the sliding member notch. The return spring biasing force on the sliding member toward the wall lightly holds the primer with uniform three point contact, two in the V shaped slide plus the wall. The slot floor does not extent to the stop, such that the floor restrains the primer in the notch until the sliding member is in the primer insertion position, at which point the primer is not supported by the slot floor and is injected into the primer cup by the plunger. The body section includes a tubular guide within which the plunger travels through a vertical path. The plunger guide comprises diametrically opposed slots that are in line with and sized to receive a linear plunger contacting ramp formed by and raised above the inner surface of trigger body section. The plunger contacting ramp extends, parallel to the direction of travel of the sliding member, from proximate to the pivotally connected trigger body end to a horizontal and perpendicular crossbar that is located above and in contact with the top of the plunger guide unless the trigger body and sliding member are in the primer insertion position. Until the trigger body and sliding member are in the primer insertion position, the contact between the crossbar and the top of the plunger guide prevents the trigger body from rotating completely and prevents the plunger contacting ramp from advancing downward in the plunger guide slots. The plunger is biased in an upward direction by a second spring and is located directly above the position of the sliding member notch when the sliding member is in the primer insertion position. The plunger is restrained from downward movement by the sliding member and is not forced downward except when the sliding member is in the primer insertion position. The trigger body section is pivotably connected to the sliding member and slideably connected to the lower body section. The inside of the trigger body section top forms the generally horizontal and integrally formed crossbar and plunger contacting ramp. A slanted finger grip portion of the trigger is located at one end of the trigger section opposite to an end that contains the plunger contacting ramp, with the pivotable connection to the sliding member between the ramp and the finger grip portion. Finger pressure applied to the finger grip portion urges the trigger section and connected sliding member toward the primer insertion position and urges the trigger body to pivot relative to the sliding member. Until the sliding member is in the primer insertion position, the plunger guide top supports the trigger body crossbar, preventing the plunger contacting ramp from advancing downward against the plunger and biasing force of the plunger spring and the upper surface of the sliding member prevent the plunger from proceeding downward. Once the sliding member is in the primer insertion position, the trigger body crossbar is advanced past the top of the plunger guide and is no longer supported by the top of the plunger guide and the plunger is free to be forced against the force of the plunger retraction spring, by contact with the plunger contacting ramp, downward through the notch to push the primer into the primer cup. When finger pressure is then released, the plunger retraction spring causes the plunger to travel upward and the force of the plunger head on the plunger contacting ramp causes the trigger body to pivot upwardly and the force of the return spring causes the sliding member to return to the primer loading position.
- The device assembly also includes a flat disc shaped tray for supplying primers to the supply trough and a mechanism for mounting the device on a reloading press. The mounting mechanism comprises an arm fastened to the top of a frame member of a press and a bar attached to the supply trough between the tray and the primer transport device. The bar is removably insertable into a bracket at one end of the mounting arm, the bracket being shaped to allow the bar to pivot such that the assembled tray, trough and the transport device is able to swing between a vertical position and a slanted position. This arrangement allows the priming tool to slightly self-correct for small height and lateral errors caused by incorrect adjustment and manufacturing tolerances. When the mounting arm is fixed in proper position to the reloading press and the assembly is complete by insertion of the bar into the bracket, the primer transport device will hang in the vertical position slightly displaced from the primer cup to allow other operations to proceed unhampered by the presence of the device. When a primer is needed, finger pressure on the trigger first swings the device into position for loading the primer directly into the primer cup, before operating the sliding member and plunger to perform the installation of the primer.
- The principle aim of the present invention is to provide a new and improved primer installation device that meets the foregoing requirements and is convenient and safe to load and operate.
- Other objects and advantages of the invention will become apparent from the Description of the Preferred Embodiments and the Drawings and will be in part pointed out in more detail hereinafter.
- The invention consists in the features of construction, combination of elements and arrangement of parts exemplified in the construction hereinafter described and the scope of the invention will be indicated in the appended claims.

FIG. 12 is a partial sectional top view of the assembled device in accord with the present invention taken alone line 12-12 shown inFIG. 10 . - With reference to the Drawings wherein like numerals represent like parts throughout the Figures, a device of the present invention for delivery of generally cylindrical ammunition primers to a conventional primer cup for installation is generally designated by numeral 10 in
FIGS. 1-12 . Conventional primers are shown in some of the drawings and designated by the numeral 100 and a conventional primer cup is designated by the numeral 102.Device 10 consists of aprimer transport device 12, aprimer supply tray 14, aprimer loading trough 16 and a mountingarm 18. Theprimer loading trough 16 is assembled between thesupply tray 14 and thetransport device 12 and comprises an internal, partiallyenclosed passage 20 having a rectangular cross section sized to accept a series of ammunition primers in a single column with enough clearance to allow primers to freely slide downpassage 20 in a proper orientation for installation but without so much excess clearance as to allow aprimer 100 to turn over while passing throughpassage 20. Aslot 19 in one wall of thetrough 16 allows observation and inspection of primers in thetrough passage 20.Primer supply tray 14 is formed as a flat round disc with anouter wall 22 and acover 24. In the preferred embodiment ofdevice 10,supply tray cover 24 is formed of a clear plastic to allow the primers in thetray 14 to be observed and inspected. Afeed slot 25 is formed in thetray wall 22 and is positioned to communicate directly withpassage 20 at afirst end 32 oftrough 16 so that a primer can travel fromsupply tray 14 through thetrough passage 20 to thetransport device 12.Primer transport device 12 comprises abody 26, a slidingmember 28 and atrigger member 30.Body 26 is molded of plastic with aslot 36 sized to receive slidingmember 28 and arectangular socket 38 for receiving thesecond end 34 oftrough 16. In the assembled and mounteddevice 10,slot 36 is generally horizontal. Ascrew 40 removably secures troughsecond end 34 withinbody socket 38. Anopening 42 in thewall 44 ofbody slot 36 is positioned adjacent to thesocket 38 and communicates withpassage 20 at troughsecond end 34 so that a primer can enterslot 36 fromtrough 16 throughbody opening 42. The slidingmember 28 is formed as a rectangular prism with a height approximately equal or less than the thickness of a primer to be installed and is movable generally horizontally withinslot 36 between a primer loading position as shown inFIGS. 6 and 7 , at which position aprimer 100 is allowed to entertransport device 12 from aprimer supply trough 16 and a primer insertion position shown inFIGS. 2 , 3, 4, 5, 8, 9, 10 and 12, at which position aprimer 100 is allowed to exittransport device 12 for insertion into aprimer cup 102. Slidingmember 28 is formed with anotch 50 open to the side ofmember 28 that is in contact with thebody slot wall 44.Notch 50 is formed with angled sides in a general “V” shape and sized so that a primer innotch 50 would be nearly, but not entirely, enclosed withinnotch 50. When slidingmember 28 is in the primer loading position, thenotch 50 is immediately adjacent to wall opening 42 such that a primer can enter notch 50 fromprimer supply trough 16. Thebody slot 36 comprises aflat floor 46 supporting the slidingmember 28 and thebody 26 forms astop 48 that prevents the slidingmember 28 from movement past the primer insertion position. Areturn spring 49 is formed of wire shaped with two 90-degree bends and being otherwise straight. Afirst end 51 ofreturn spring 49 engagesslide 28 and asecond end 53 engages and is secured bybody 26. The slidingmember 28 is generally biased byreturn spring 49 in the direction of the primer loading position.Return spring 49 is slightly angled relative tobody 26 to additionally biasslide 28 towardwall 44 ofbody slot 36 such that the part of aprimer 100 not completely withinnotch 50 bears againstwall 44 and the primer is lightly but effectively held while slidingmember 28 is being advanced to stop 48. Thenormal primer 100 being cylindrical and the force ofspring 49 being mild, theprimer 100 is gently squeezed while in transit between the primer loading position to the primer insertion position, traveling throughbody slot 36. Theslot floor 46 ends at a sufficient distance fromslide stop 48 that whenslide 28 engages stop 48 and is at the primer insertion position,slot floor 46 does not extend belownotch 50 and aprimer 100 innotch 50 is unsupported and is ready to be inserted into theprimer cup 102. - The primer
transport device body 26 forms a generally vertical tubular,plunger guide 52 within which aplunger 54 travels through a vertical path.Plunger guide 52 is located immediately above the section ofslot 36 to whichslot floor 46 does not extend such thatplunger 54 is located directly above the position of the slidingmember notch 50 when the slidingmember 28 is in the primer insertion position. An opening intoslot 36 at the bottom ofplunger guide 52 is large enough to allowplunger 54 to travel downward intoslot 36, and is smaller than the inside dimension ofplunger guide 54, thereby creating an upward facingannular shoulder 62.Plunger 54 is biased in an upward direction by ahelical spring 56 compressed between anenlarged plunger head 60 andshoulder 62. When slidingmember 28 is in the primer insertion position, notch 50 is positioned directly belowplunger 54, which is then able to travel downward intonotch 50. -
Trigger member 30 is connected to slidingmember 28 by apivot 66 and is slideably restrained by the interaction of a flange 68 formed as part of thebody 26 and a rail 70 formed as part of thetrigger 30.Trigger member 30 is movable horizontally with slidingmember 28 between the two positions. A raisedsurface 72 is formed by inner surface at the top of thetrigger member 30 and is positioned to contactplunger head 60 and provide downward pressure on theplunger 54. A slanted and slottedfinger grip 74 is located at one end oftrigger member 30 nearest to pivot 66. -
Plunger guide 52 comprises diametricallyopposed slots 75 with an axis that is parallel to the direction of travel of slidingmember 28 and are in line with and sized to receiveplunger contacting ramp 72.Plunger contacting ramp 72 extends, parallel to the direction of travel of slidingmember 28, from proximate totrigger finger grip 74 to a horizontal andperpendicular crossbar 73 that is located above and in contact with the top ofplunger guide 52 when thetrigger member 30 and slidingmember 28 are not in the primer insertion position. Until thetrigger member 30 and slidingmember 28 are in the primer insertion position, the contact between thecrossbar 73 and the top of theplunger guide 52 prevents thetrigger member 30 from rotating completely and prevents theplunger contacting ramp 72 from advancing downward into theplunger guide slots 75.Plunger 54 is located directly above the position of the slidingmember notch 50 when the slidingmember 28 is in the primer insertion position.Plunger 54 is not forced downward except when slidingmember 28 is in the primer insertion position. - Finger pressure applied to the
finger grip 74 causes triggermember 30 and slidingmember 28 to slide from the loading position toward the primer insertion position. Until slidingmember 28 is in the primer insertion position, the top ofplunger guide 52 supports thetrigger body crossbar 73, preventingplunger contacting ramp 72 from advancing downward againstplunger head 60 and opposing the biasing force of theplunger spring 56. - Once the primer insertion position has been reached and stop 48 is contacted by sliding
member 28, the sliding motion is stopped and theplunger 54 is directly aboveslide notch 50 and triggerbody crossbar 73 is advanced past and is no longer supported by the top ofplunger guide 52 andplunger 54 is free to advance downward. When the primer insertion position is reached,plunger 54 can be forced downward against the force of the plunger retraction spring, 56 by contact with and pressure fromplunger contacting ramp 72,plunger 54 advancing downward and being accelerated by continued finger pressure ontrigger member 30, which is thus able to pivot in a counterclockwise direction aboutpivot 66.Plunger 54 is thereby moved downward throughnotch 50, compressingspring 56 and pushing aprimer 100 fromnotch 50 into theprimer cup 102. When finger pressure is then removed fromtrigger 30, the return force ofspring 56 againstplunger head 60 causes plunger 54 to travel upward, and the force exerted byplunger head 60 ontrigger surface 72 causes trigger 30 to rotate in a clockwise direction aboutpivot 66 to the original orientation. At the same time, the linkedtrigger 30 and slidingmember 28 are returned to the primer loading position byreturn spring 49. -
Device 10 is assembled with thesupply tray 14 above thetransport device 12 and connected thereto bysupply trough 16. Primers can be loaded intotray 14 by removal oftray cover 24 and thetray 14 or the primers manipulated to assume the proper orientation with the proper side up. After the primers are loaded into thetray 14, thedevice 10 is connected to the mountingarm 18 andsupply tray 14 becomes relatively vertical with the primers on their sides and able to travel by gravity through thetray feed slot 25 and thence into and throughtrough 16. The separation betweensupply tray cover 24 and the bottom oftray 14 and the interior space ofslot 25 andtrough passage 20 formed by the separation between the supply trough top and bottom and the separation between the top surface ofdevice body slot 36 andbody slot floor 46, all have a similar clearance, which is at least slightly greater than the thickness of a primer to be installed and at least slightly less than the diagonal width of a primer to be installed, such that the tray, trough and body together constitute a primer channel that is of limited dimension to maintain the orientation of a primer to be installed and prevent the primers from inverting into an upside down orientation.Supply trough 16 is curved before joiningtransport device 12 so that primers are rotated 90 degrees from thetray 14 to thetransport device 12. Mountingarm 18 comprises ahorizontal bar 82 with screw holes for fixation to the top of a frame member of a press, not shown, at one end and abracket 86 at the other end. Aflat bar 88 is attached to supplytrough 16 between thetray 14 and theprimer transport device 12 and is removably insertable intobracket 86.Bracket 86 is formed of avertical plate 90 and a pair of slantedrestraints 92 joined to thevertical plate 90 at the bottom and angled outward at the top so thatflat bar 88 is allowed to swing between a vertical position and an angled position when inbracket 86. Atop restraint 94 preventsbar 88 from being inadvertently displaced out ofbracket 86. Belowbracket 86, a thin,flexible blade 96 formed of a flexible plastic, extends vertically downward to contact thetrough 16 and maintaindevice 10 in a relatively vertical position. The mountingarm 18 is to be secured to the reloading press in such position that thedevice 10 is out of the way of other press operations when not in use, but can be swung into proper position for installation of a primer. When a primer is needed, finger pressure ontrigger 30first swings device 10 into a slanted position for loading the primer directly into the primer cup, before operating the slidingmember 28 and then plunger 54 to perform the installation of the primer. - While preferred embodiments of the foregoing invention have been set forth for purposes of illustration, the foregoing description should not be deemed a limitation of the invention herein. Accordingly, various modifications, adaptations and alternatives may occur to one skilled in the art without departing from the spirit and the scope of the present invention. It is specifically anticipated a variety of materials could be suitable for use in constructing
device 10 without departing from the spirit of this invention.
