Description

The present invention relates to a conventional type of counting device designed to mechanically produce results for various arithmetic operations.

In FIG. 1 denotes a general perspective view of the device; FIG. 2, 3 and 4 parts.

The device consists of a part for adding and subtracting (Fig. 1) - multiplying and dividing B and auxiliary part A (Fig. 1) for postponing the obtained results from all actions and auxiliary actions on extracting roots and other auxiliary works. All parts can be connected dumbly, on special hinges, permanent or seminal, and for greater portability, can be foldable, with parts L and L can be folded, imis under part B and placed in a special case with outer walls of material adapted dl easy to erase. x records.

Parts of the device A and A (Fig. 1) are the same. In the frame-box 1, several are inserted, arranged in a row moving along the length of the box, slats or bars 2 (Fig. 1), identical in size and symbols of the signs on them from O, 1, 2, to 9, which differ from the first bar . The length of bars 2 is made in such a way that with their full movement to failure, up or down marked on these or other zero signs fall in the middle of the frame-box. The entire length of the frame-box 1, between the bars 2, passes the fixed membranes 3 to isolate the other bars from movement while one of them moves by the action of the handle (handle) (Fig. 1). Box 1, together with parts, is covered with a lid 4, which has a width-wide edge-from edge to edge — result window 5, motor slots (for

manipulator penetration and) 6, going from the resultant window 5 in the up and down directions, and also along one edge or along both digits of the index from 1 to 9 inclusive, going from the resultant window 5 also up and down and ending in both cases x signs of zeros at the same height with motor slots b (Fig. 1). From each digit of the index, there are lines 7 for the orientation of the eye, which calculates when operated with the manipulator at the top when adding and at the bottom of the result window 5 when subtracting numbers or vice versa. The bars 2, for the convenience of moving them up or down, have transverse locking grooves 8 between the image of the symbols (Fig. 1). In the board of one of the parts of the device along it there is a hole made with a wide screw thread at the beginning or with some other fixing device for placing the handle (manipulator) serving to move the bars 2 with its metal end. The other end of the handle is provided with an ordinary pencil or pen.

Part B (Fig. 1), used for multiplying and dividing numbers, consists of a grafted board of box 12, with the usual multiplication table, where against digits 1, 2, 3, 4, 5, b, 7, 8 and 9, located along the edge of the table and other similar figures (index) located along the other edge, at right angles to the line of the first, from the top and bottom of each figure are vertical and horizontal lines, forming quadrilaterals intersected by diagonals separating tens from the units in the numbers enclosed in each quadrangle and representing the product of the opt. GOVERNMENTAL unambiguous index numbers of the table above. In the case of the absence of diagonals, the individual signs of the works are distinguished by the places or the features of the outlines or image of the NII. In combination with the preceding Part A of the instrument, all actions of arithmetic are performed. Instead of a grafted board, the table may consist of individual flat bars 11 (Fig. 2) inserted into a common frame 12 so that they can be taken out from the ends facing the outside of the frame and rearranged from place to place between them in accordance with the data for action (multiply or divide) numbers.

The bars can also be four-sided to fill in the response numbers (products) of each face in a special number of the split index.

In all cases, a closing device is arranged to eliminate scattering of the calculator by unnecessary products, and to open the necessary ones only, consisting of racing strips 14 and 14 (Fig. 2) coming out, just like bars 11, from the frame 12, but not completely removed from the frame 12. Two fingers grasped by two fingers, when one of the planks is to be pulled out, and several fingers and one hand along the several planks, the planks are slid out and open the necessary works (Fig. 1). In order for the strips 14 and 14 not to jump out of the box-frame 12 at this time, since they can always be extended to the full, there is a special adaptation under the ends of the strips 14 and 14. The sun box 12 is covered with glass or some other transparent glass. solid material, attached, approximately, by a special frame or cogs 15. To keep the slats from falling out, along each of the two sides, part 5 of the device, through which the gripping ends of the slats 14 and 14 pass, are laid along the same axis 16, fixed by their ends with the frame - box 12. Under each plan Second, under zahva7nym its end, on an axle 16 has one freely rotatable on this axle suspension 17, an acute angle locking entrance present in notch 18 on the lower side

strips 14 or 14; There are two such notches under each plank; one is located under the gripping end of the plank most out of the box-frame, and the other is under the opposite end of it. The first notch prevents each bar from being pulled out when the adjacent bar is pulled out and from falling out of the device, and the second bar holds the bar being pulled out at the moment, preventing it from leaving the device completely when the covered table bar is completely open. under it on the bar 11 (Fig. 11).

Instead of bars 2, eight eight or ten triangular prisms (Fig. 3) turning on their axes can be used, identical in their structure and character patterns on them and in the desired quantity, with columns of multiplication placed on their edges, set as shown in the diagram (Fig. 4). Magnifying glasses 22 (FIG. 4) may be located above the prisms for better visibility of the digital symbols. Between the transparent-expanding plates 22 there are interlayers 23 that cover the faces that are unnecessary in this action from the eye.

During the arithmetic operations performed using the proposed device, for appropriate permutations, the handle (manipulator), rotation of the prisms, movement of bars, etc., are used in accordance with the basic principles of design of all counting machines.

The subject of the patent.
