Abstract
Abstract A marking gun for printing adhesive labels with pricing and the like having a printing head connected to an operating trigger for impressing the labels, and a drive wheel linked to the operating trigger by a ratchet and pawl assembly for incrementally advancing the labels carried on a backing tape by engaging radial drive teeth on the drive wheel into perforations in the backing tape after the pre-cut adhesive labels have been impressed by the printing head and separated from the backing tape.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
250 words
In an adhesive label printer having an operating trigger and a printing head with a plurality of selectable characters, the printer being adapted to operate in combination with pre-cut adhesive labels carried on a separable backing tape with spaced perforations, the improvement comprising a drive assembly adapted to incrementally transport the labels and backing tape on predetermined paths including: a. a reciprocating pivot arm having the operating trigger mounted at one end and the printing head mounted at the opposite end, said arm being pivotally mounted in the printer for reciprocal movement between a preoperative position and a marking position by operation of the trigger; b. a cylindrical drive wheel having radially disposed drive teeth arranged to engage the perforations in the backing tape and having an integral ratchet wheel with a predetermined number of drive seats, said drive wheel being rotatably mounted in the printer adjacent the pivot arm; c. a spring member having one end mounted in the printer and an extension end biased to selectively engage a seat of said ratchet wheel and restrain movement of said ratchet wheel and said drive wheel when said arm is moved from the preoperative position to the marking position by displacement of the trigger; and d. a pawl pivotally linked to said pivot arm and arranged to engage a seat of said ratchet wheel and advance said drive whEel a predetermined increment when said arm is moved from the marking position to the preoperative position by return of the trigger.
Claim 2
Dependent Claim
250 words
In an adhesive label printer having an operating trigger and a printing head with a plurality of selectable characters, the printer being adapted to operate in combination with pre-cut adhesive labels carried on a separable backing tape with spaced perforations, the improvement comprising a drive assembly adapted to incrementally transport the labels and backing tape on predetermined paths including: a. a reciprocating pivot arm having the operating trigger mounted at one end and the printing head mounted at the opposite end, said arm being pivotally mounted in the printer for reciprocal movement between a preoperative position and a marking position by operation of the trigger; b. a cylindrical drive wheel having radially disposed drive teeth arranged to engage the perforations in the backing tape and having an integral ratchet wheel with a predetermined number of drive seats, said drive wheel being rotatably mounted in the printer adjacent the pivot arm; c. a spring member having one end mounted in the printer and an extension end biased to selectively engage a seat of said ratchet wheel and restrain movement of said ratchet wheel and said drive wheel when said arm is moved from the preoperative position to the marking position by displacement of the trigger; and d. a pawl pivotally linked to said pivot arm and arranged to engage a seat of said ratchet wheel and advance said drive whEel a predetermined increment when said arm is moved from the marking position to the preoperative position by return of the trigger.
Claim 3
Dependent Claim
78 words
The adhesive label printer of claim 1 wherein the printing head, and the drive wheel and pawl described therein are selectively replaceable with a printing head having a multiple plurality of selectable characters, a drive wheel having drive teeth arranged to engage perforations in a backing tape with more distantly spaced perforations and a pawl arranged to engage a modified ratchet wheel and advance said drive wheel an increased predetermined increment for use with labels of increased size.
Claim 4
Dependent Claim
130 words
In the adhesive label printer of claim 1, the improvement comprising further: a. a printing guide plate fixed in the printer and so constructed and arranged that the adhesive labels and backing tape are supportable on the guide plate, and the printing head is directed against a printing portion of the guide plate and is contactable with at least one label supported thereon when said pivot arm is in said marking position; and b. biasing means for imparting a pressure against said guide plate at a location adjacent the printing portion and maintaining adhesive labels and backing tape, arranged between said biasing means and guide plate, against said guide plate; said biasing means cooperating with said drive wheel to impart a tension to said back tape at said printing portion.
Claim 5
Dependent Claim
22 words
The improvement of claim 3 comprising further means connected to said guide plate for removing said adhesive labels from said backing tape.
Claim 6
Dependent Claim
55 words
The improvement of claim 4 wherein said means connected to said guide plate comprises a guide tip roller attached to the end of said guide plate, and guide means for switching said backing tape around said roller, the adhesive labels separating from said backing tape at said roller from an inherent stiffness of the labels.
Claim 7
Dependent Claim
55 words
In the adhesive label printer of claim 1, the improvement comprising further: a. guide means mounted in the printer having a guide element complementary to said cylindrical drive wheel, the guide element having recesses adapted to receive drive teeth on the periphery of the drive wheel as said teeth are projected through the backing tape.
Claim 8
Dependent Claim
16 words
The improvement of claim 6 wherein said guide element is spring biased against said drive wheel.
Claim 9
Dependent Claim
31 words
In the adhesive label printer of claim 1, the improvement comprising further, roller means having an ink supply engageable with selected characters on said printing head for inking said selected characters.
Claim 10
Dependent Claim
27 words
The combination of an adhesive label printer of claim 1 and a label supply having pre-cut adhesive labels carried on a separable backing tape with spaced perforations.
