Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
159 words
An improved supply and transfer apparatus for a cigarette packing machine which transfers groups of twenty cigarettes into compression pockets carried on an intermittent motion conveyor of said cigarette packing machine, said compression pockets being indexed adjacent said supply and transfer mechanism, said apparatus comprising: (a) at least three transfer chambers, each receiving a group of cigarettes, each of said transfer chambers being in registration with one of three adjacent compression pockets on said conveyor when said conveyor is indexed; (b) hopper means connected to said transfer chamber for receiving a supply of cigarettes and distributing said cigarettes to said transfer chambers; (c) at least three plungers being operated simultaneously to engage the groups of cigarettes in said transfer chambers and insert the cigarettes into the three adjacent compression pockets in registration with said transfer chambers when said conveyor is indexed; and (d) means for operating said plungers only after at least each third successive index of said conveyor.
Claim 2
Dependent Claim
159 words
An improved supply and transfer apparatus for a cigarette packing machine which transfers groups of twenty cigarettes into compression pockets carried on an intermittent motion conveyor of said cigarette packing machine, said compression pockets being indexed adjacent said supply and transfer mechanism, said apparatus comprising: (a) at least three transfer chambers, each receiving a group of cigarettes, each of said transfer chambers being in registration with one of three adjacent compression pockets on said conveyor when said conveyor is indexed; (b) hopper means connected to said transfer chamber for receiving a supply of cigarettes and distributing said cigarettes to said transfer chambers; (c) at least three plungers being operated simultaneously to engage the groups of cigarettes in said transfer chambers and insert the cigarettes into the three adjacent compression pockets in registration with said transfer chambers when said conveyor is indexed; and (d) means for operating said plungers only after at least each third successive index of said conveyor.
Claim 3
Dependent Claim
74 words
The apparatus of claim 1, wherein said hopper means include: (a) a reservoir section for receiving a supply of cigarettes; (b) vein sections having at least three feed paths, each containing three feed veins for directing said cigarettes from said reservoir section to said transfer chambers; and (c) means for agitating said cigarettes in said reservoir sections to prevent clogging of said feed paths so that the cigarettes will move into said feed veins.
Claim 4
Dependent Claim
46 words
The apparatus of claim 2, wherein said transfer chambers have three compartments, each compartment communicating with a feed vein, said transfer chambers being positioned so that the compartments are generally in a vertical position, whereby gravity will move the cigarettes into the compartments from the veins.
Claim 5
Dependent Claim
43 words
The apparatus of claim 3, wherein each of said plungers includes three pusher elements, each pusher element being inserted into a single compartment of said transfer chambers to insert the cigarettes in said compartment into said compression pocket upon operation of said plunger.
Claim 6
Dependent Claim
42 words
The apparatus of claim 1, wherein said transfer chambers have three compartments adjacent to one another for receiving cigarettes from said hopper means, said compartments being positioned generally vertically, whereby gravity will move the cigarettes into the compartments from said hopper means.
Claim 7
Dependent Claim
43 words
The apparatus of claim 5, wherein each of said plunger includes three pusher elements, each pusher element being inserted into a single compartment of said transfer chamber to insert the cigarettes in said compartments into said compression pockets upon operation of said plunger.
Claim 8
Dependent Claim
30 words
The apparatus of claim 1 wherein said conveyor is a rotatable turret and wherein said transfer chambers are positioned adjacent to turret at the eleven, twelve and one o'clock positions.
Claim 9
Dependent Claim
37 words
The apparatus of claim 7, wherein said plungers are located adjacent the eleven, twelve and one o'clock positions and are adapted to insert the cigarettes in the transfer chambers into the compression pockets on the rotary turret.
Claim 10
Dependent Claim
124 words
The apparatus of claim 1, wherein said means for operating said plungers includes: (a) bracket means for carrying said plungers; (b) a connecting rod having a first end pivotedly secured to said bracket means; (c) a lever having one end pivotedly secured to said packing machine and the other end pivotedly secured to the other end of said connecting rods; (d) a cam follower carried on said lever; (e) a positive movement cam engaged by said cam follower so that said plungers can be inserted and removed from said transfer chambers only after at least each third successive index of said conveyor; and (f) means connected to said packing machine drive mechanism and synchronized with said conveyor movement for driving said positive movement cam.
