Abstract

Abstract A pill counting machine in which a plurality of pills are moved by elongated vibrating troughs which first form a single line of pills, then remove the dust, and finally pass the pills through a sensing station where they are counted. A diverting vane adjacent the sensing station switches the direction of the stream of pills into a storage means after the desired number of pills has passed the sensing station.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 268 words
A combined counter and dispenser for a plurality of discrete objects comprising: a. a first elongated trough to receive a quantity of the said objects, said trough having an open exit end thereon, b. vibration imparting means coupled to the first trough to advance the objects therealong, c. a second elongated trough having a substantially arcuate cross-sectional shape and an open exit end thereon, disposed so as to receive the objects coming from the first elongated trough, d. a second vibration imparting means coupled to the second trough to advance the objects therealong, e. elongated openings in the bottom portion of the second trough disposed in the path of the objects, whereby dust or particulate matter on the objects may be removed from the second trough, f. a counter assembly including a source of light which generates a beam directed across the path of the objects as they leave the exit end of the second trough, a photosensitive device positioned adjacent to the second trough exit end, g. a manually operated start means for said counter, said start means including a first lever secured to a start handle, a magnetically releasable latch armature for latching the first lever into a start position, a bell crank coupled to the first lever including a first and a second arm, and a switch connected in series between a source of electrical power and a clutch winding in the counting means, said switch positioned in line with the second arm for actuation when the bell crank is operated by the start handle, and h. an electric counter coupled to the photosensitive device.
Claim 2
Dependent Claim 268 words
A combined counter and dispenser for a plurality of discrete objects comprising: a. a first elongated trough to receive a quantity of the said objects, said trough having an open exit end thereon, b. vibration imparting means coupled to the first trough to advance the objects therealong, c. a second elongated trough having a substantially arcuate cross-sectional shape and an open exit end thereon, disposed so as to receive the objects coming from the first elongated trough, d. a second vibration imparting means coupled to the second trough to advance the objects therealong, e. elongated openings in the bottom portion of the second trough disposed in the path of the objects, whereby dust or particulate matter on the objects may be removed from the second trough, f. a counter assembly including a source of light which generates a beam directed across the path of the objects as they leave the exit end of the second trough, a photosensitive device positioned adjacent to the second trough exit end, g. a manually operated start means for said counter, said start means including a first lever secured to a start handle, a magnetically releasable latch armature for latching the first lever into a start position, a bell crank coupled to the first lever including a first and a second arm, and a switch connected in series between a source of electrical power and a clutch winding in the counting means, said switch positioned in line with the second arm for actuation when the bell crank is operated by the start handle, and h. an electric counter coupled to the photosensitive device.
Claim 3
Dependent Claim 46 words
A counter according to claim 1 wherein said first lever is coupled to a second lever for actuating a stop switch to stop the counting action, said second lever including a permanent magnet pad for engagement with a ferromagnetic slab for positive actuation of the switch.
Claim 4
Dependent Claim 45 words
A counter according to claim 2 wherein said first and second arms are coupled to a diverting trough positioned at the exit end of the second trough for changing the direction of movement of the objects after a predetermined number of objects have been counted.
Claim 5
Dependent Claim 23 words
A counter according to claim 2 wherein said firsT and second levers are rockable about a first shaft secured to the start handle.
Claim 6
Dependent Claim 37 words
A counter according to claim 2 wherein said first and second arms of the bell crank are rockable about a second shaft, said first arm is coupled to the second lever and resiliently stressed for contact therewith.
Claim 7
Dependent Claim 35 words
A counter according to claim 2 wherein said magnet pad is made of resilient material impregnated with ferromagnetic particles for eleminating bounce from the second lever when it is moved into contact with said slab.
