Abstract
A primer collator useful with primer tubes includes a funnel, sorting assembly, output ramp assembly, and counting assembly. The funnel rotates and directs primers to a sorting assembly, which defines slots formed by a priming disc and timing disc that cooperate and rotate within a disc housing. In each slot, a lower ramp and ridge section and upper tooth section are configured to interact with primers to stop improperly oriented primers. Properly oriented primers travel through the slots to an outer groove formed by the disc housing to be transported to the output ramp. The counting assembly counts primers as they travel on the output ramp and powers off the collator after a preset number of primers are counted. Additional features include a magnetic tube attachment assembly and a timing assembly that meters the dispensing of primers into the tube while also stabilizing them to prevent errors.

(19) For a better understanding of the invention reference is made to the following detailed description of the preferred embodiments of the invention which should be taken in conjunction with the above described drawings.
DETAILED DESCRIPTION OF THE INVENTION
(20) The present invention relates to a novel and useful primer collator 10 for use with standard primer tubes 20 as shown in
(21) As shown in
(22) Motor 106 preferably attaches to housing 104 immediately below sorting assembly 110 such that an output shaft 107 of motor 106 can be positioned to cooperate with sorting assembly 110 components. Motor 106 is preferably a small low power 12 volt motor and causes output shaft 107 to rotate either clockwise or counterclockwise about a central axis X, as shown in
(23) Controller 108 or parts of controller 108 can be attached or positioned anywhere in housing cavity 104A and is preferably positioned to cooperate with and electrically communicate with motor 106, a power switch 15, counting assembly 160, and any other components as needed. Controller 108 includes any necessary components necessary to process user inputs, operate the motor 106, and facilitate counting of primers 30 with counting assembly 160. Controller 108 preferably houses together or among connected components any necessary control and processing components 109 such as a processor, memory, input and output components, wireless or wired communication components, or any other feature of a computer or controller system as is well known in the art. Software can be stored on the controller's memory and is preferably executable by the processor to perform many tasks, including, for example, counting the number of primers that travel pass the counting assembly sensor or initiating a pause in sorting when primers jam and cause a backup of primers on the output ramp. For example, if primers stack up on the output ramp such that they cover the counting assembly sensor and no longer move past it, controller software and hardware can stop the motor, display a visual warning using the counting assembly light source, and pause counting. After the operator clears the jam, he can restart the motor to resume counting or remove and empty the collator primers from the primer tube, reset the counter so that it counts anew, and restart the motor.
(24)
(25) Sorting assembly 110 sits between funnel 100 and housing 104. Preferably, sorting assembly 110 includes a disc housing 120, a primer disc 130, and a timing disc 140 that work together to form several rotatable and irregular slots 138 into which primers 30, 40 fall when the slots are positioned closest to the ground or in a down position. In
(26)
(27) Nested substantially inside walls 128 and adjacent the upper surface 121A of disc housing plate 121 is primer disc 130, the preferred features of which are illustrated in
(28) Positioned adjacent the upper surface 131A and raised sections 133 of primer plate 131 is timing disc 140, the preferred features of which are illustrated in
(29)
(30)
(31) Counting assembly 160 includes a counter housing 162 that preferably fixedly attaches to ramp 152 near sensor channel 153A. A first portion (not labeled) of counter housing 162 extends below sensor channel 153A and supports a light sensor 166 positioned directly below sensor channel 153A. A second portion (not labeled) of counter housing 162 extends up and over output ramp 152 and supports a light source 164 positioned directly above sensor channel 153A. The light source is preferably a light emitting diode. Together, the light sensor 166 and light source 164 cooperate to register when a primer passes over sensor channel 153A, and light fails to reach light sensor 166. With control and processing components that are separate from or included with control and processing components 109 of controller 108, counting assembly 160 counts every time a primer passes over opening 153A. Preferably, after a given number of primers 30 have been counted, primer collator 10 is powered off or a warning alert is activated. Also preferably, the operator of primer collator can reset the counter when needed.
(32) Pivotally attached to pivot connection 125 of disc housing 120 is a timing lever 172. Timing lever 172 has a first end 172A that cooperates with steps 146 of timing disc 140 and a second end 172B that cooperates with a connection rod 174. Timing lever 172 is preferably connected with a torsion spring (not shown) that biases first end 172A of timing lever 172 toward the center of timing disc 140. Connection rod 174, which is preferably a steel rod such as a thin 1 mm spring-steel rod, links second end 172B to a first end 176A of a stabilizing arm 176. Connection rod 174 movably attaches to timing lever 172 and stabilizing arm 176 so that it does not distort during movement. Stabilizing arm 176 pivotally connects at first end 176A to ramp 152 or support 151 such that it is positioned next to ramp 152 and ramp groove 153. Stabilizing arm 176 also includes a hammer section 178 near a second end 176B of stabilizing arm 176 that extends into ramp groove 153 through ramp slot 157, as shown in detail in
(33) Primer tube 20 can be properly oriented to cooperate with output channel 156 by using an optional and preferred tube connection assembly 180 as shown in
(34) To operate primer collator 10, an operator attaches a primer tube 20 to the output ramp 152 at connection channel 181 below output channel 156, preferably using magnet housing 186 and adaptor 182. The operator then pours primers 30, 40 into funnel 100 and waits as funnel 100 and sorting assembly 110 sorts primers 30, 40. Any primer resting on its bottom surface 54 or top surface 50 will fall into slots 183 formed by timing disc 140 and primer disc 130 as they rotate. Any primer resting on its side remains in funnel 100. As anvil-side-up primers 30 rotate in slots 183, they encounter output ramp 123 in disc housing 120 and are consequently delivered to output ramp 152. As anvil-side-down primers 40 rotate in slots 183, they eventually slide back into funnel 100 to be sorted again. The sorted anvil-side-up primers 30 that are delivered to output ramp 152 then slide down ramp groove 153 of output ramp 152. As they slide down groove 153, they are counted by the counting assembly 160. At the same time, the timing assembly 170 and stabilizing arm 176 prepare primers 30 to fall into primer tube 20 correctly by catching and holding each primer 30 with stabilizing arm 176 as timing lever 172 interacts with steps on timing disc 140. After stabilized, each primer 30 falls into the attached primer tube 20 positioned below and output channel 156 of ramp 152. After counting 100 primers 30, the counting assembly 160 tells primer collator 10 to stop sorting. The operator can then remove primer tube 20 and empty it into a fixed primer tube on a reloading press or otherwise use it with a priming tool to reload ammunition. It is estimated that primer collator 10 can fill a primer tube with 100 primers in about 45-60 seconds.
(35) While in the foregoing, embodiments of the present invention have been set forth in considerable detail for the purposes of making a complete disclosure of the invention, it may be apparent to those of skill in the art that numerous changes may be made in such detail without departing from the spirit and principles of the invention.
