Description

The invention relates to a counting machine based on the principle of logarithmic movement of a lever of the first kind. This machine makes it possible to perform all four arithmetic operations.

In the attached drawing of FIG. 1 gives a diagram of a counting machine according to the invention; FIG. 2 is a diagram of the logarithmic movement of a lever of the first kind.

The counting machine consists of two main parts, the L-fixed with the final mechanism and S-movable with a dial mechanism.

Part B (carriage) moves along the sled 14 left and right, and to the left it can move with the help of a straight toothed rack 13, handle 10 and doggie 12, moving with each turn of the handle one division of the final column 9; The separating edge of the movable and fixed parts of the machine corresponds to the dotted line B.

The fixed part consists of box A, inside of which is placed the final mechanism, which is a set of disks 1, 2, 3, 4 with numbers on the rims of disks 1 and 3, ten on each axis O to 9. Movement from the larger disk 3 to small 1 transmitted by (261)

endless perforated tape

The disk 3 is transmitted by the movement of the fork b, which in turn receives movement from the levers 24 of the carriage B. The small disks 1 are interconnected by a mechanism according to the rev counter principle so that each full turn of one disk moves the adjacent disk one division. Then, if we count from right to left, the first disk gives units, the second decade, then hundreds, etc. There are ten sets of disks in total (1, 2, 3, 4) with plug 5 in the mechanism.

Fork 5, with multiplication and addition, operates with one side as shown in the drawing, and with division and subtraction, with the other side, for which there is a special switch.

The entire final mechanism is fixed on the fixed part of the machine so that when the carriage B moves, the levers 24 freely pass under the forks 5, stopping against them with the possibility of transmitting movement to them.

The typesetting mechanism of the carriage B consists of ten levers 24, resting on one side on the movable arm 6, and the other on, fixed under the roller 15, with the possibility of the latter sliding along the levers 24 while moving. Prop 6

Moves in parallel with j gaps 28 that have grippers 23 outside the box. With the aid of pointer 25, the support stops at the required number of the chambers 26. The pointer moves along the slots 27. The roller 15 is fixed on the levers 16, receiving movement from the handle 10, moved along direction of the arrow and back. During the reverse movement of the handle 10, the dog 12 operates, the carriage is moved one division.

The keys 22, mounted on the leads 19, when pressed, transmit movement to the cranked levers 18. The reverse movement of the keys is obtained using springs 20. The levers 18 have different lengths, depending on the required rotation of the levers 24. The length of the levers 18 corresponds to the numbers of the keys 22. The greater the span must have a lever 24, the shorter the lever 18. The levers 18 are pivotally mounted on the roller 29.

On the phage. 2 shows the action of the levers 24. The position of the lever D shows the effect of multiplying 5X6-30.

The method of using the masin in multiplying and dividing is as follows: the multiplicand is dialed using leads 28 with grippers 23 and pointer 25, on scales 26, as on a conventional calculator, multiplier using the keys 22. The product is obtained in a row of windows 8.

When the multiplicand is dialed, press the key corresponding to the first digit of the multiplier (one). Turning the handle 10 towards yourself to failure, in the row of windows 8, we obtain the product of a multiplier by a multiplier. When the handle is reversed, the carriage moves from one to the left by one division. After that, press the key corresponding to the second digit of the multiplier (ten), turn the knob again. The product changes accordingly, and so on. For control, the multiplier is automatically obtained in column 9.

When dividing, the fork 5 is pressed to the other side 4 by means of a special switch. Then the disks with numbers work in the opposite direction.

The dividend is shown in column 8. The divisor is scaled on scales 26-27. Moving the carriage to the left, one should divide the divider under the extreme digits of the dividend and, using keyboard 22, perform the action as an arithmometer in the usual order. In column 9, the quotient is obtained.

The subject matter of the invention.

Claims (4)

1. A counting machine for producing four arithmetic operations, using levers 24 of the first kind placed in a movable carriage B, the support points 6 of which are movable by means of t 28 for setting them on logarithmic scales 26 and which serve when pressing the key 22 and when moving the handle 10, to move the fork 5 controlling the final mechanism located in the stationary part A of the machine. 2. In the counting machine according to claim 1, to limit the movement of the rychas 24, the levers 18 of different lengths in accordance with the keyboard numbers operated by the keys 22 and hinged on the roller 29. 3.In the car on the PP. 1 and 2, the use of the lever 10, which, when rotated in one direction, serves to control the movement of the lever 24 until it touches the lever 18, and when rotated to the other side, causes movement of the carriage B, by means of the pawl 12 and the toothed rack 13, to one / step. 4.In the car on the PP. 1-3 the device of the fork 5 is rotatable for the purpose of coupling it with the disk 3 on one side of the multiplication and addition side and the other side when dividing and subtracting. cpnri
