Abstract: 756,942. Cartridge-operated tools. PORTABLE INDUSTRIES, Inc. June 9, 1953 [Feb. 3, 1953], No. 15821/53. Class 119 An explosively operated tool for firing fasteners 20 or like devices into hard surfaces, comprises a housing 25, a barrel 30 movable axially with respect to the housing between the normal position, Fig. 1, and the firing position, Fig. 4, and an element 50 carried by the barrel for engaging a retractible projection 46 carried by a firing pin 45 slidably mounted in the housing. The housing also carries a trigger 55 which when pulled retracts the projection into the housing and thus releases the firing pin. The barrel shown is acted upon by a spring 31 which is compressed when the tool is pressed against the workpiece. During the relative movement of the barrel and housing the leading round from magazine 32 enters the barrel chamber. At the same time, the nose of the next fastener in the magazine is depressed by a ramp 44b, Fig. 8, on the rear end of the barrel, further ramps 44a engage surfaces 34d, Fig. 5, on a magazine part 34 thus depressing the latter against the action of, a spring 35, and finally wedging-surfaces 44c engage and force outwardly the cartridge case retaining lips 34a of the magazine to release the leading fastener unit. In the meantime, the pin 50 extending rearwardly from the barrel has moved the projection 46 rearwardly against the action of a firing pin spring 48. Firing is effected by a pull on the trigger 55, such action serving to lift the production and release the firing pin. When the tool is removed from the workpiece the cartridge case is extracted by an extractor 65 and ejected by the next fastener through an opening 25d. Lips 33f on the magazine in conjunction with a slidable sleeve 70, Fig. 2, serve to hold the magazine in place, a catch device 71 associated with the sleeve incorporating also a screw 72 serving also to lock a barrel retainer ring 77 within the housing 25 and preventing relative rotation between the barrel and housing. The muzzle end of the barrel has an enlarged bore 91a to house a disc which is penetrated by a fastener, and the handle 27 of the tool is formed with a bore 27d for housing a supply of discs, the end of the box terminating in a groove to facilitate their removal one at a time.

Abstract: 998,443. Delivering paper. A. KIMBALL CO. April 22, 1963, No. 15821/63. Heading B6H. [Also in Divisions B8 and G4] Price tags T bearing information in the form of perforations and having three feed holes are fed one by one from an input stack in timed relation to the rotation of a pair of feed wheels 38, Fig. 11, which have specially shaped pins 36 round the periphery thereof for engaging the feed holes of the tags T. Each pin 36 has a tapered portion which first enters the feed holes in the tags and facilitates positioning of the holes exactly over the cylindrical bases of the pins before wheels 38 apply any driving force to the tags. A pair of spring-loaded members 42, 44 have annular grooves to accommodate pins 36, and define the outer surface of the feeding path. A pair of discs (not shown), mounted on shaft 190 outside the wheels 38 guide the edges of the tags T. Feed wheels 38 move the tags past a sensing station, and in response to the sensed information the tags may be directed to one or other of two output stacks. A stripper block 222 co-operates with a roller 224 which is driven faster than the tag feed to remove the tags from wheels 38 and direct them to a pair of deflectors 48. A rotary solenoid is controlled by the sensing station to rotate shafts 230 on which deflectors 48 are mounted so as to deflect the tags T on one side or the other of sleeves 52 which surrounds shafts 230.
