COMPUTiNG-S'CALE OR OTHER CALCULA'l'iNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 580,783, dated April 13, 1897.

Application filed September 23, 1895. Serial No. 563,290. (No model.)

To all whom it may concern.-

Be it known that I, FREDERICK L. FULLER, a citizen of the United States, residing at Trenton, county of Mercer, and State of New Jersey, have invented certain new and useful Improvements in Computing-Scales or other Calculating-Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to improvements in calculating-machines intended for use by accountants or storekeepers, either alone for the purpose of figuring sums generally or to be applied to computing-scales or the like for the purpose of automatically figuring and indicating the cost of goods sold at diiferent rates.

The present invention has for its object the provision of such an apparatus which will have the very important advantage of simplicity and cheapness in construction over practical apparatus of the character heretofore devised and which will also at the same time be absolutely reliable and certain in its operations.

In the accompanying drawings, Figure 1 illustrates a calculating mechanism embodying the present invention applied to a weighin g-scale, the several parts being shown in zero position. Fig. 2 is a similar view of a portion of Fig. 1, illustrating the several parts of the calculating apparatus in the positions they occupy after an operation of said apparatus. Fig. 3 is a section on the line 3 of Fig. 1. Fig. 4 is a section on the line 4 of Fig. 3. Fig. 5 is a section on the line 5 of Fig. 1.

The invention has for convenience been illustrated in the drawings as applied to a weighing-scale, because in such connection it has peculiar advantages, but it is to be understood that broadly the invention is independent of such combination.

Referring to said drawings, 1 represents an ordinary scale-beam, and 2 its poise, the beam being provided with the usual pound index or scale. The parts of the scale illustrated are, except for the poise 2, of substantially well-known construction and therefore need no further description here. The poise 2 has formed integrally with it a hood or frame 8,

in which is a rotating dial 4., connected to a stud 5, provided with a pinion 0, engaged by a rack 7, by which the pinion and dial are, as will presently appear, rotated to make an indication through sight-opening S in the face-plate 9 of the hood 3. The rack 7 is located upon the inner face of the plate 9 and is provided with guide-pins l0 and 11, projecting through a vertical slot in said plate, by which the rack is guided vertically. The lower guide-pin 11 enters a longitudinal slot 12 in an angular actuating or controlling member, herein shown as a lever 13, fulcrumed at its inner end at 14. to the scale-beam and at its outer end entering a recess 15 in the outer end of the scale-beam. (See Fig. 5.) The indicating dial -1 moves with the poise in weighing, and as it is thus moved it is actuated by the angular member 13, through the rack 7, to an extent depending upon the angular position of the angular member 13 with relation to the beaml, which latter acts as a support and guide for the indicating mechanism, through the poise 2, during such movement. The angular member 13 normally occupies the position in which it is shown in Fig. 1that is to say, with its slot 12 in parallelism with the scale-beam 1and while it occupies this position the poise 2 and hood 3 may be moved back and forth, as in a simple weighing operation, without effecting any movement of the rack 7. This position of the angular member or lever 13 is its Zero position, and means are provided for adjusting its outer end to and from the scale-beam to thereby vary its angularity in accordance with variations in rates per pound, to thereby cont-rel or determine the operation of the indicating mechanism, as will now be described. The outer end of angular member 13 is, as shown in Figs. 1 and 2, provided with a segmental rack 16, which is engaged by a pinion 17, carried by a rotatable dial 18, mounted in the end of the scale-beam,upon rotating which by hand the angular member 13 is raised or lowered, as the case may be, to greater or less degrees of inclination with reference to the scale-beam, according to the extent of rotation of the dial 18, which is governed by the rate per pound or other unit of the goods, the

price whereof is to be computed. To guide the operator in this, the outer face of dial 18 is provided with a rate index or scale, which makes its indication at the point 19 of the scale-beam, as shown in Fig. 2. As the dial, therefore, is rotated it will, through rack 1t and pinion 17, correspondingly raise or lower the angular member or lever 13 into position for operating the rack 7 and dial 4 in accordance with the rate per pound or other unit indicated upon the dial 18.

The operation of the apparatus is as follows: The parts, as before stated, are, as shown in Fig. 1, in zero position, and if the poise 2 be moved along the beam the pin 11 of rack 7 will move through the slot 12 idly and without any movement being imparted to the rack 7. Let us assume that an article is to be weighed the price per pound of which is twenty-five cents. The dial 18 will first be rotated from zero until the numeral 25 comes opposite the point 10. As the dial is thus rotated the angular member 13 is raised and adjusted angularly with reference to the scalebeam 1. The parts then occupy the position shown in Fig. 2. The goods being placed upon the platform of the scale, the poise 2 is moved along the beam 1 in the usual way until it balances. As the poise is thus moved the angular member 13, through its slot 12, engaging the pin 11, raises the rack 7 and through it rotates the (11:114., and this upward movement of the rack will continue until the poise is brought to rest. If the weight of the goods be live pounds, this will occur at the numeral. 5 on the scale-beam index and the angular member 13 will have raised the rack 7 until the numerals 125that is, the sum of live by twenty-five-appear at the sight-opening 8, as shown in Fig. 2. 1f the rate per pound for the goods next weighed be greater, the dial 18 is farther rotated in the same direction thus increasing the degree of inclination of the angular member 13, or, if it be less, the movement is reversed, thus decreasing it. The operation may be reversed that is, the weight of the article may be ascertained in the usual manner first, after which dial 18 is rotated to correspond with the unit price, said movement raising the end of angular member 13, which movement causes the elevation of rack 7 and rotary movement of dial 4 through the action of angular member 13 on stud 11 of rack 7. In addition to index upon dial 18 there may be provided a stationary deci mal-ind ex 20, beginning at the left of the point 19, if decimal rates be employed.

It will be seen that the line 21 is five and one-fourth spaces, that line 22 is ten and onehalf spaces, and that line 23 is fifteen and three-fourths spaces to the left of line 19 that is, the lines 21, 22, and are one fourth, one -half, and three -fourths of a space, respectively, to the left of the three five-cent graduation-lines to the left of line 19, so that if the rate per pound included a fraction, as in the case of twenty-five and one-fourth cents, it would only be necessary to rotate the dial until the number 25 rested opposite the line 19, which would give the twenty-five cent rate. Then by continuing to rotate dial until the number 20, which would be the first long line (five-cent graduation) to the left of line 19, rested opposite line 21 this extra rotation would be onefourth of one space. The lines 21, 22, and 23 are separated, so as to make it plain for the operator and accomplish the same result as if they were placed one-fourth, one-halt, and three-fourths of one space, respectively, from line 10.

It will be evident that the indicating movement of the indicating mechanism is determined or controlled as to its operation or iiidication by the angularity of the angular member, whether such member constitutes the means for actuating suchindicating mechanism or merely controls its actuation or movement.

Opening 8 of hood 2: is covered by glass, on the inner side of which is scratched or painted line said line determining the proper place at which amount shown by indicating mechanism should be read.

My invention of course is not limited to the particular embodiment or construction herein shown, for the same may be varied within the spirit and scope of my invention.
