Application filed February 23, 1912. Serial No. 679,522.

To all whom it may concern."

Be it known that I, GEORGE W. Gross, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Calculating-Machines, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure l is a plan view of a calculating machine of my improved construction. Fig. is a cross sectional View taken on the lines 2-2 of Fig. 1. Fig. 3 is a cross sectional view taken on the line 8-3 of Fig. 1. Fig. 4 is a perspective view of the forward end of an arm that forms a connection between the worm shaft and the extensible scale forming a part of my improved machine. Fig. 5 is an enlarged cross sectional view taken on the line 5-5 of Fig. 1.

This invention relates generally to calculating machines and more particularly to that class of machines utilized for multiplying or dividing in order to quickly and accurately ascertain a result where two factors are known.

The machine herein shown and lescribed is particularly designed for readily ascertaining the cost or selling price of cotton which is usually put up in large bales and the price per pound of which varies from day to day, and which cost or price sometimes goes into mills and fractional parts of mills. To correctly figure the cost or selling price of a large number of bales of cotton of different weights and at a price including cents, mills and fractional parts of mills per pound without the use of some mechanical means or rate sheets involves considerable time and labor, and it is the purpose of my invention to provide a simple machine which can be easily and quickly operated and which will accurately indicate the results where a commodity is being bought and sold for an amount of money running into cents and mills and fractional parts of mills.

In the following description the machine is referred to as being particularly adapted for calculating values and weights of cotton, but it will be readily understood that the same machine with changed scales or indicating marks can be readily utilized for quickly and correctly ascertaining the weights and cost or selling prices of grain, hay coal, ore or any commodity that is sold in bulk or by weight, and said machine can also be utilized for calculating taxes, interest and the like.

To the above purpose my invention consists in certain novel features of construction and arrangement of parts hereinafter more fully described and claimed.

In the construction of the machine as shown f make use of a rigid frame comprising a pair of vertically disposed end plates 10 and a series of longitudinally disposed rails 11, the ends of which are rigidly fixed to said plates 10. The central one of these rails 11 is provided with a series of marks 12 arranged in equal distance apart, which marks are consecutively numbered so as to form a scale, which, in the present instance represent-s cents;

13 designates a shaft which occupies a po sition in front of the central one of the rails 11 and the ends of this shaft are journaled in the plates 10. This shaft is provided with a right hand thread 14: and a left hand thread 15 which are of the" same pitch and extending from one end of the shaft to the other. Mounted on the right hand end of this shaft outside the right hand plate 10 is a disk 16 having a milled edge whereby it may be readily engaged and turned, and formed on the inner edge of this disk is an inclined face 17 provided with a graduated scale 18 having 100 equal divisions, and formed on said inclined face immediately adjacent this scale is a second scale 19 having 32 equal divisions. The scale 18 reprefrequently goes into eighths, sixteenths and thirty-seconds of a cent.

Loosely mounted on the end of the shaft 13 adjacent to the right hand plate 10 is a pointer 20, the outer end of which overlies corresponding end plate 10 is a set screw 23.

By loosening this set screw the pointer 20 may be adjusted as desired.

Fixed on the left hand end of the central one of the rails 11 is a block 24, and pivotally mounted thereon is one end of a plate '25 which bears loosely upon the rear one of the rails 11, and hinged to the upper end of this plate 25 is a corresponding plate 26. These plates 25 and 26 are provided on their top surfaces with a graduated scale which is numbered from 350 at the lower end of the plate 25 to 700 at the lower end of the plate 26, and this scale represents the pounds of the commodity that is bought and sold. In the present instance this scale is numbered from 350 to 700 for the reason that practically all bales of cotton weigh within these limits.

The lower end of the plate 26 is pivotally mounted on a sleeve 27, which latter is mounted to slide freely on the central one of the rails 11, and formed integral with and extending forwardly fromsaid sleeve is an arm 28, the forward end of which is provided with a split bearing 29. This bearing encircles the shaft 13, and formed on the interior of said bearing is a spirally disposed rib or feather 30 that engages in the right hand thread 14: of the double threaded shaft13.

Mounted for sliding movement upon the lower front one of the rails 11 and the shaft 13 is a carriage '31, and positioned thereon to the rear of the shaft 13 is a housing 32 in which is arranged a counting and indicating mechanism comprising a series of four or five disks or counting wheels arranged side by side and connected so that when one of said wheels or disks has made one revolution it operates the adjacent wheel or disk and moves the same one-tenth of a revolution, and likewise the adjacent wheel upon making a complete revolution imparts partial rotation to the next adjacent wheel.

I make no claim about the particular form of counting and indicating mechanism utilized, as there are a number of existing types of devices that eanbe obtained in the market and advantageously utilized with my improved machine. Mounted on the shaft of this counting and indicating mechanism is a pinion 33 with which meshes a larger pinion 34, and which latter is fixed to the hub of a disk 35 having a milled edge, and mounted for rotary movement upon the shaft 13. Fixed on the interior of the hub of this disk is a spirally disposed rib 36 that engages in the left hand groove 15 of the shaft 13. Thus when the disk 35 is rotated the hub 36 engaged in the groove 15 will cause said disk, the carriage 31 and the housing 32 to slide lengthwise upon the shaft 13 and the lower front one of the rails 11. At the same time the pinion 34 imparts rotary motion to the pinion 33, and as a result, the counting wheels or disks within the housing 32 are correspondingly actuated. Fixed to the housing 32 and projecting rearwardly therefrom in a plane immediately above the plane occupied by the extensible scale comprising the plates 25 and 26 is an arm 37. Carried by this arm is a transparent plate 38, and formed thereon is a longitudinally disposed line or mark 39 which serves as a guide for positioning the counting and indicating mechanism relative to the extensible scale. The position of the extensible scale is con trolled by means of the disk 16.

The operation of my improved calculating machine is as follows: Assuming that a buyer is purchasing a bale of cotton weighing 578 pounds at 11?; cerits per poundthe disk 16 is manually engaged and rotated so that the bearing 29 and sleeve 27 is moved into position so that the left hand end of the sleeve 27 is in a position between the marks on the central one of the rails 11, designated by the numbers 11 and 12, and the operator now continues to rotate said disk 16 until the mark designated by 75 of the scale 18 is tions the extensible scale comprising the plates 25 and 26 for retaining the total cost of the bale at a price of 11% cents per pound, and the operator now rotates the disk 35 in the proper direction to move the carriage and counting and indicating mechanism along the shaft 13 until the line 39 on the transparent plate 38 is in a position directly above the point or indicating mark 578 on the scale. During the rotary movement of the disk 35 the pinion 34 imparts rotary movement'to the pinion 33 in turn actuating the counting wheels or disks within the housing 32 and when the parts have been brought to the proper position with the line 39 over the proper mark on the ex tensible scale the counting wheels or disks will show through the opening in the top of the housing 32, the correct result of 57 8 multiplied by 11%, namely 6791, which is the value in dollars and cents of the bale of cotton under consideration.

It will be readily understood that the operations just described and which consist of manually rotating the disks l6 and 35 can be very rapidly performed, and thus where a large number of bales of cotton differing in weight are being sold much time and labor is saved in ascertaining the exact price to be paid for each individual bale.

As hereinbefore stated, my improved calculating machine can be advantageously used for ascertaining the price of any commodity which is sold by weight and at varying prices per pound, as, for instance, wagon and carloads of grain, coal, mineral, baled hay or any commodity that is sold in bulk and at prices which fluctuate from day to By changing the numbers upon the scales a machine of my improved construction may be advantageously employed in ascertaining taxes, interest and for any and all calcu lations where two factors are known. W here a large amount of a certain commodity is purchased for a lump sum price and it is desired to quickly ascertain the exact price per pound paid for the commodity the operator rotates the disk 35 until the number representing the price paid appears on the counting and indicating wheels through the opening in the top of the housing 32, and the disk 16 is now rotated until the line 39 is directly over the mark on the extensible scale indicating the weight of the commodity, and when these operations have been completed the parts will be so positioned as that'the price per pound is indicated by the position of the.

sleeve 27 on the central one of the rails 11 and the position of the scales on the disk 16 relative to the indicating mark 21 on the finger 2-0. 7

It will be readily understood that minor changes in the size, form and construction of the various parts of my improved calculating machine can be made and substituted for those herein shown and described without departing from the spirit of my invention, the scope ofwhich is set forth in the appended claims.
