Abstract
Abstract A stock feed and shear system which may be utilized in an automatic ticket vending machine for cutting tickets from different rolls of stock and delivering the tickets to other components such as a printer and a magnetic encoding transport. The rolls are supported on reels having releasable clamp mechanisms for allowing rapid replacement of spent reels while providing a predetermined drag between the roll cores and the reels. The reels are spring loaded so that stock can be unwound from the rolls only by positively driving the same with selectively driven pinch rollers. Guide tracks direct the stock to a rotary shear which cuts single ticket lengths from the stock without metal to metal contact, thereby achieving excellent service life. Sensors provide an indication of spent rolls, completion of a cutting operation, and presence of a ticket in the shear. In another embodiment paper or plastic tickets are pre-cut by a two-way rotary shear and are held in escrow. Thereafter either type of ticket may be selectively driven past a print head by a special drive connection to a single motor. A replacement ticket is cut and held in escrow, thereby eliminating feeding and cutting time in the ticket dispensing operation.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
235 words
A system for cutting tickets from rolls of stock comprising: a pair of reels each for carrying a roll of stock having a free end, and each including means for releasably clamping a core portion of the roll; means for rotatably supporting each of the reels including means for providing a reverse rotational bias on each of the reels in a direction opposite to the direction of rotation required to unwind stock from the roll carried thereby; a shear including a rotary blade and an opposing fixed blade defining a path therebetween for stock, the rotary blade cutting the stock upon rotation thereof without contacting the fixed blade; first sensor means for detecting the presence of stock in the shear path; a pair of ticket guide tracks each for directing the free end of the rolls from the reel carrying the roll to the path of the shear; second sensor means for detecting the presence of stock along each of the guide tracks; feed means for engaging and selectively propelling the free ends of the rolls along corresponding ones of the guide tracks through the path of the shear; drive means for rotating the rotary blade to cut a portion representing a ticket from stock fed from either of the rolls; and third sensor means for sensing the amount of rotation of the rotary blade to detect the completion of the cutting of a ticket.

Claim 3
Dependent Claim
254 words
A system according to claim 1 and further comprising: a second fixed blade opposing the rotary blade defining a second path therebetween for stock; the ticket guide tracks being configured to direct stock from the rolls through respective ones of the paths past the rotary blade; means for defining a pair of upper and lower channels aft of the rotary blade for receiving tickets cut from stock directed through corresponding ones of the paths; an upper drive roller for engaging a ticket in the upper channel and propelling it therethrough away from the rotary blade and the guide tracks; a lower drive roller for engaging a ticket in the lower channel and propelling it therethrough away from the rotary blade and the guide tracks; means for defining a ticket channel positioned and configured for having tickets from the upper and lower channels propelled therethrough; a ticket drive roller for engaging and propelling a ticket through the ticket channel; a motor having a shaft; and means for rotatably mounting the drive rollers adjacent the channels and drivingly connecting the drive rollers to the motor shaft so that energizing the motor in one direction will cause a ticket in the upper channel to be propelled into and through the ticket channel while a ticket in the lower channel remains stationary, and so that energizing the motor in the other direction will cause a ticket in the lower channel to be propelled into and through the ticket channel while a ticket in the upper channel remains stationary.
