Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
296 words
An apparatus for crushing a cylindrical can which comprises: (a) a base, (b) a horizontal frame affixed to said base and having two opposed ends, (c) an anvil mounted near one end of said frame, (d) a movable ram positioned on said frame and facing said anvil, (e) a crushing chamber affixed to said frame for supporting said can in the horizontal position between the anvil and the ram, such that one end of said can is positioned adjacent said anvil and the other end of said can is positioned adjacent said ram, and (f) a drive means for moving the ram toward the anvil and includng a power means, a means for transmitting said power means to the movable ram, and means for engaging and disengaging said power means, to crush said can disposed therebetween, said drive means comprising a first drive mechanism including a driver pulley mounted on the motor shaft, a driven pulley mounted on a first shaft, and a belt operatively connecting the driver pulley to the driven pulley to impart rotational motion to the first shaft; a second drive mechanism including a first chain wheel mounted on said first shaft, a second chain wheel mounted on a second shaft and a drive chain for operatively connecting the first chain wheel to the second chain wheel and imparting rotational motion to the second shaft; and a third drive mechanism including a pinion gear mounted on said second drive shaft and a ram assembly slidably mounted on said horizontal frame, said ram assembly having the ram affixed to one end thereof and having a rack gear affixed to the other end of said rod, and (g) a means for moving said ram away from said anvil to allow removal of the crushed can.
Claim 2
Independent Claim
296 words
An apparatus for crushing a cylindrical can which comprises: (a) a base, (b) a horizontal frame affixed to said base and having two opposed ends, (c) an anvil mounted near one end of said frame, (d) a movable ram positioned on said frame and facing said anvil, (e) a crushing chamber affixed to said frame for supporting said can in the horizontal position between the anvil and the ram, such that one end of said can is positioned adjacent said anvil and the other end of said can is positioned adjacent said ram, and (f) a drive means for moving the ram toward the anvil and includng a power means, a means for transmitting said power means to the movable ram, and means for engaging and disengaging said power means, to crush said can disposed therebetween, said drive means comprising a first drive mechanism including a driver pulley mounted on the motor shaft, a driven pulley mounted on a first shaft, and a belt operatively connecting the driver pulley to the driven pulley to impart rotational motion to the first shaft; a second drive mechanism including a first chain wheel mounted on said first shaft, a second chain wheel mounted on a second shaft and a drive chain for operatively connecting the first chain wheel to the second chain wheel and imparting rotational motion to the second shaft; and a third drive mechanism including a pinion gear mounted on said second drive shaft and a ram assembly slidably mounted on said horizontal frame, said ram assembly having the ram affixed to one end thereof and having a rack gear affixed to the other end of said rod, and (g) a means for moving said ram away from said anvil to allow removal of the crushed can.
Claim 3
Dependent Claim
64 words
The apparatus of claim 1, wherein the means for engaging and disengaging the power means includes a friction clutch lever and a third pulley located between the driver pulley and the driven pulley to provide sufficient tension on the belt and thereby engage the pulleys, and a second clutch means for engaging the pinion gear on the rack gear portion of the ram rod.
Claim 4
Dependent Claim
33 words
The apparatus of claim 2, wherein the crushing chamber has a semicylindrical bottom wall and a semicylindrical loading door hinged to said bottom wall which together define the dimensions of the crushing chamber.
Claim 5
Dependent Claim
49 words
The apparatus of claim 3, including connecting means affixed to said loading door and said second clutch means to engage said pinion gear with said rack gear when the loading door is closed and to disengage said pinion gear from said rack gear when the loading door is open.
Claim 6
Dependent Claim
24 words
The apparatus of claim 4, wherein said friction clutch lever includes a handle mounted to said frame for manually engaging the friction clutch lever.
Claim 7
Dependent Claim
39 words
The apparatus of claim 3, wherein said apparatus is characterized by a control mechanism operatively connected to said ram rod and responsive to a predetermined movement of said loading door in a direction toward the normal operating position thereof.
Claim 8
Dependent Claim
36 words
The apparatus of claim 3, wherein the semicylindrical bottom wall has a drop slot adjacent said anvil for removing the can from said chamber after the can has been crushed between the ram and said anvil.
Claim 9
Dependent Claim
23 words
The apparatus of claim 7, wherein the semicylindrical loading door has a portion beveled outwardly adjacent said anvil and above said drop slot.
Claim 10
Dependent Claim
30 words
The crushing chamber of claim 3, wherein said chamber has a horizontal axis and said ram moves in said chamber toward or away from said anvil along said horizontal axis.
Claim 11
Dependent Claim
22 words
The apparatus of claim 1, further including a counter means for recording the number of cans crushed during operation of said apparatus.
