SU26107A1 - Device for repeated installations on the drum of the adding machine of the required number - Google Patents

Description

For repeated installations on the drum of the adding machine of the required number, a device is proposed, consisting of the mounting on the cover of the adding machine either directly or on the lattice scarvy with slots corresponding to the slots on the adding machine.

FIG. 1 depicts a view of the fit and above; FIG. 2- the same side view; FIG. 3 is the same cross-sectional view; FIG. 14-13 parts of the fixture in different projections.

On the cover of the adding machine i, the lattice 1 is installed either freely or on the hinge 15 with slots 2 facing against the slots on the adding machine, S of which the locking rods 3 are movably mounted and between which the branches of the lattice extend. The numbers on these branches correspond to the numbers on the “calculator of the adding machine. The locking rods 3 are advanced along their slots and set against the required diffr. After all the teeth of the 5th drum of the adding machine are installed on the zeros, the lattice is thrown onto the adding machine and then a small turn of the handle (in the opposite direction) is made, as for setting the teeth to the initial position; the teeth are retained by the lower ends of the locking rods and, thus,

form the required number on the drum of the adding machine.

The locking rod 3 consists of a rod b, provided with a (screwed) head 7, which needs to be pressed a little so that the rods can be moved to another digit, and a slider 8 in which the rod is installed and pulled up to the top by a spring 9.

The locking rod is provided in the lower part with a transverse paired protrusion 10. Which, when the rod is pulled up, enter the slots 11 of the lower longitudinal bar of the branch of the lattice 4 (stopper). The slider is provided with lateral protrusions 12, which slide along the guide groove 13 in the body of the branch 4, when the locking rod moves (along the slit 2). On the bottom of the slider there is a paired protrusion 14, between which, not exiting from it, the lower part 10 of the locking rod slides, when pressing its head.

The subject matter of the invention.

Device for re-installation on the drum of the adding machine of the required number, characterized by the use of mounted on the cover of the adding machine directly or on the hinge 15 of the lattice for 1 s. slots 2, the corresponding slots on the adding machine and equipped with movable locking rods installed in them W. servants delays the arithmometer teeth in certain: the same places corresponding to the required number.
