A crutch constructed of two adjacently located, elongated, parallel upper and lower bows which can be moved in relationship to each other to form a vertical support of readily varied length. These bows have the same design and are therefore interchangeable, significantly reducing inventory requirements. Each bow has a series of parallel horizontal notches with the bows positioned so that the notches on each bow are on contacting surfaces. A pin inserted into parallel, adjacent notches on the two bows in cooperation with two or more collars or caps on the ends of one end of each bow fixes the relationship between the shafts which, in turn, defines the length of the vertical support. A similar concept can be used to lock a moveable centrally located lower bow between two parallel outer upper bows. This assemble provides a strong, adjustable length crutch for any height patient using only two different pairs of bow lengths.

A machine for operating on blanks, comprising: a machine frame; at least one impression member supported by the frame; at least one rotary print roll supported by the frame and disposed proximate to the impression member, wherein the impression member and the print roll define therebetween a nip for receiving the blanks in series and transporting the blanks through the machine; at least two ink applicators for each print roll, each ink applicator comprising a rotary ink roll and an ink chamber mechanism disposed adjacent the ink roll, with each ink roll disposed proximate to the print roll and each ink applicator supported by the frame, wherein the ink chambers apply ink to the corresponding ink roll, which selectively apply ink to the print roll, which prints on the blanks; at least two applicator adjustment mechanisms, wherein one applicator adjustment mechanism is operatively connected to one ink applicator and the other applicator adjustment mechanism is operatively connected to the other ink applicator, wherein each ink applicator can be moved between an engaged position and a retracted position relative to the print roll in response to actuation of the corresponding applicator adjustment mechanism; and at least two primary actuators, wherein one primary actuator is operatively connected to one applicator adjustment mechanism and the other primary actuator is operatively connected to the other applicator adjustment mechanism. 3. The machine of claim 2, wherein one of the ink applicators can be disposed in the engaged position for printing while at the same time another one of the ink applicators can be disposed in the retracted position for cleaning. 4. The machine of claim 3, wherein each ink chamber mechanism comprises a support member, an ink well coupled to the support member, and two or more blades extending from the ink well and contacting the corresponding ink roll for applying ink to the ink roll. 5. The machine of claim 4, wherein each ink chamber mechanism further comprises a pivotal member that is coupled to the corresponding support member and that supports and permits a pivotal movement of the ink well, wherein the ink well can be pivoted away from the corresponding ink roll for accessing the ink well. 6. The machine of claim 3, wherein each ink cham
