Abstract
Abstract A coin sorting and access control mechanism for a vending machine comprising a central wall member having chute-forming members pivotally mounted on either side thereof and biased toward the central wall. Each chute is provided, at the upper portion thereof, with a funnel located so as to receive coins inserted through a slotted coin plate by a consumer wishing to gain access to the product being vended. The coin mechanism includes a funnel having multiple-apertured coin contacting surfaces which lead to coin transfer chutes. The coin transfer chutes, and the central wall therebetween, are provided with elongated slots extending therealong. The chute walls are also provided with surfaces which minimize coin surface area contact. Thus, the funnels, slots, and coin contacting surfaces minimize any surface tension which might arise in moisture between the mechanism and coins inserted into the machine.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
288 words
In a coin actuated outdoor apparatus having a coin chute therein, the improvement for reducing surface tension between the walls of said chute and a wet coin inserted therein while stripping moisture from the wet coin during its passage through said chute, said improvement comprising: said chute having opposed generally parallel surfaces; said surfaces being spaced apart a distance which slightly exceeds the thickness of a coin to be inserted into said chute such that at least one of said generally parallel surfaces contacts at least one surface of the inserted coin, means formed on said generally parallel surfaces to reduce the surface tension between said surfaces and a coin inserted in said chute, said means to reduce surface tension including raised portions on at least one of said generally parallel surfaces such that contact between said surfaces and a coin within said chute being thereby reduced by the presence of said raised portions, whereby the presence of water on said apparatus or on coins inserted in said chute during inclement weather has a reduced tendency to cause sticking of coin within said chute, said chute being formed by a central wall and adjacent spaced wall members, a plurality of pawls mounted on the lower end of said chute and cooperating with coins in said chute to effect actuation of said apparatus when proper coinage is deposited in said chute, funnel means cooperating with said coin chute and receiving coins to be fed into said chute, and said funnel means including means to permit water contacting said funnel to pass therethrough and to reduce surface tension tending to cause a coin to stick in said funnel when one or both of said coin or said chute are wet.
Claim 2
Dependent Claim
288 words
In a coin actuated outdoor apparatus having a coin chute therein, the improvement for reducing surface tension between the walls of said chute and a wet coin inserted therein while stripping moisture from the wet coin during its passage through said chute, said improvement comprising: said chute having opposed generally parallel surfaces; said surfaces being spaced apart a distance which slightly exceeds the thickness of a coin to be inserted into said chute such that at least one of said generally parallel surfaces contacts at least one surface of the inserted coin, means formed on said generally parallel surfaces to reduce the surface tension between said surfaces and a coin inserted in said chute, said means to reduce surface tension including raised portions on at least one of said generally parallel surfaces such that contact between said surfaces and a coin within said chute being thereby reduced by the presence of said raised portions, whereby the presence of water on said apparatus or on coins inserted in said chute during inclement weather has a reduced tendency to cause sticking of coin within said chute, said chute being formed by a central wall and adjacent spaced wall members, a plurality of pawls mounted on the lower end of said chute and cooperating with coins in said chute to effect actuation of said apparatus when proper coinage is deposited in said chute, funnel means cooperating with said coin chute and receiving coins to be fed into said chute, and said funnel means including means to permit water contacting said funnel to pass therethrough and to reduce surface tension tending to cause a coin to stick in said funnel when one or both of said coin or said chute are wet.
Claim 3
Dependent Claim
41 words
The apparatus of claim 1 wherein said chute and said parallel surface are inclined with respect to the vertical, whereby moisture stripped from a coin inserted into said chute may fall downwardly in a generally lateral direction away from said chute.
Claim 4
Dependent Claim
203 words
In a coin actuated outdoor apparatus having a coin chute therein, the improvement for reducing surface tension between the walls of said chute and a wet coin inserted therein while stripping moisture from the wet coin during its passage through said chute, said improvement comprising: said chute having opposed generally parallel surfaces; said surfaces being spaced apart a distance which slightly exceeds the thickness of a coin to be inserted into said chute such that at least one of said generally parallel surfaces contacts at least one surface of the inserted coin, means formed on said generally parallel surfaces to reduce the surface tension between said surfaces and a coin inserted in said chute, whereby the presence of water on said apparatus or on coins inserted in said chute during inclement weather has a reduced tendency to cause sticking of a coin within said chute, said generally parallel surfaces having means resiliently biasing them to a closed position in which the said surfaces are spaced apart a distance which slightly exceeds the thickness of a coin to be inserted into said chute, and said surfaces being movable away from each other to an opened position to release slugs or coins from said chute.
Claim 5
Dependent Claim
203 words
In a coin actuated outdoor apparatus having a coin chute therein, the improvement for reducing surface tension between the walls of said chute and a wet coin inserted therein while stripping moisture from the wet coin during its passage through said chute, said improvement comprising: said chute having opposed generally parallel surfaces; said surfaces being spaced apart a distance which slightly exceeds the thickness of a coin to be inserted into said chute such that at least one of said generally parallel surfaces contacts at least one surface of the inserted coin, means formed on said generally parallel surfaces to reduce the surface tension between said surfaces and a coin inserted in said chute, whereby the presence of water on said apparatus or on coins inserted in said chute during inclement weather has a reduced tendency to cause sticking of a coin within said chute, said generally parallel surfaces having means resiliently biasing them to a closed position in which the said surfaces are spaced apart a distance which slightly exceeds the thickness of a coin to be inserted into said chute, and said surfaces being movable away from each other to an opened position to release slugs or coins from said chute.
Claim 6
Dependent Claim
23 words
The apparatus of claim 3 wherein said means to reduce surface tension comprises a plurality of apertures formed in said generally parallel surfaces.
Claim 7
Dependent Claim
41 words
The apparatus of claim 3 wherein said chute and said parallel surfaces are inclined with respect to the vertical, whereby moisture stripped from a coin inserted into said chute may fall downwardly in a generally lateral direction away from said chute.
Claim 8
Dependent Claim
52 words
The apparatus of claim 3 including a central portion and longitudinal edge portions along either side of said central portion on at least one of said generally parallel surfaces; and said central portion being elevated with respect to said edge portions, whereby said central portion contacts a coin inserted into said chute.
Claim 9
Dependent Claim
19 words
The apparatus of claim 3 including at least one longitudinal slot formed in one of said generally parallel surfaces.
Claim 10
Dependent Claim
52 words
The apparatus of claim 3 including funnel means to initially receive a coin inserted into said chute, said funnel means including converging surfaces which lead to said generally parallel surfaces, and said funnel means serving to convey coins to the region of said chute which is bounded by said generally parallel surfaces.
Claim 11
Dependent Claim
14 words
The apparatus of claim 3 wherein said outdoor apparatus is a newspaper vending machine.
