Punching device for punching paper comprises a frame, a cooperating base supporting the frame, a plurality of individual punches removably and changeably mounted in the frame and an operating handle for actuating the punches. The frame is made of a single sheet of metal which is bent to form a U-shaped punch holding section comprising an upper portion, a lower portion and a portion connecting the upper and lower portions at one side and a die section which is joined with the lower portion of the punch holding section by a fold line and underlies such lower portion with an intervening space to receive the material to be punched. The upper portion and lower portion of the punch holding section have aligned bearing holes removably to receive and guide spring biased punches and the punching section has aligned punching holes to receive the lower ends of the punches when actuated by the operating handle. The base of the punch is formed of resilient plastic material and comprises a first portion closing the rear open side of the punch holding section of the frame, a second portion supporting the frame and a third portion which underlies the punching holes of the frame and provides a container in position to receive punchings. Flexible edge portions of the first portion of the base are engageable in annular recesses formed in the punches to provide means for removably retaining the punches in the holes of the frame in which they have been inserted.
A punching device for punching paper and like sheet material comprising a frame, a cooperating base supporting said frame, individual punches removably and interchangeably mountable in said frame and an operating handle for actuating said punches, said frame comprising a single sheet of metal shaped to form a punch-holding section of U-cross section comprising an upper portion, a lower portion and a portion connecting said upper and lower portions at one side, the opposite side being open, and a die section joined with said lower portion by a fold line and underlying said lower portion with a space between said lower portion and said die section to receive the material to be punched, said upper portion and lower portion having aligned bearing holes to receive and guide said punches, and said die section having punching holes aligned with said bearing holes and adapted to receive the lower ends of said punches when actuated by said operating handle.
A punching device for punching paper and like sheet material, comprising a plurality of individual punch assemblies, a frame having means for removably and interchangeably receiving a selected number of said punch assemblies with selected spacing between said punch assemblies and for guiding and supporting said punch assemblies for punching operation, a base of resilient plastic material supporting said frame, an operating handle for actuating said punch assemblies when in said frame and means integral with said base for removably retaining said punch assemblies in said frame to prevent accidental dislodgement of said punch assemblies from the frame.
A punching device for punching paper and the like comprising a plurality of individual punch assemblies including punching rods, a frame for removably and interchangeably receiving a selected number of said punch assemblies with selected spacing between said punch assemblies and for guiding and supporting said punch assemblies for a punching operation, a base of resilient plastic material supporting said frame, and an operating handle for actuating said punch assemblies when in said frame, said frame comprising a punch-holding section of U-cross section comprising an upper portion, a lower portion and a portion connecting said upper and lower portions at one side, the opposite side being open, and a die section underlying said lower portion with a space between said lower portion and said die section to receive the material to be punched, said upper and lower portions having aligned bearing holes to receive and guide said punching rods, and said die section having punching holes aligned with said bearing holes and adapted to receive the lower ends of said punching rods when actuated by said operating handle, said plastic base comprising three integral sections joined with one another by flexible hinge lines, namely a first section closing the otherwise open side of said frame, a second section underlying and supporting a rear portion of said die section and a third section underlying a forward porton of said die section and comprising a receptacle to receive punchings, said third section being swingable about the flexible hinge line joining it with said second section to open said receptacle for emptying punchings therefrom.
A punching device for punching paper and the like, comprising a plurality of like individual punch assemblies each comprising a punching rod and a spring secured thereto, a frame for removably and interchangeably receiving a selected number of said punch assemblies with selected spacing between said punch assemblies and for guiding and supporting said punch assemblies for a punching operation, a base for supporting said frame, an operating handle for actuating said punch assemblies when in said frame, said frame comprising a punch-holding section comprising an upper support portion, a lower support portion and a portion connecting said upper and lower support portions, said upper and lower support portions having aligned holes for slidably receiving said punching rods, each of said springs being conically wound with a smaller top convolution and a larger bottom convolution and each of said punching rods having a domed head with an annular groove in which the top convolution of the respective spring snaps to secure said spring in assembled relation with said punching rod and the bottom convolution being adapted to rest on said upper support portion of said frame, and means engageable with said punching rods between said upper and lower support portions of said frame to retain said punch assemblies on said frame to prevent their accidental dislodgement while permitting manual removal of said punch assemblies from said frame.
