ADDING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 748,924, dated January 5, 1904.

Application led March 16, 1903. Serial No. 147.988. (No model.)

T0 a/ZZ whom it may concern:

Beit known that. I, FRANCIS BURnsH, a ciri- Zen of the United States, and a resident of Mapleleaf, in the county of Howard and State of Iowa, have invented a new and Improved Adding-Machine, of which the following is a full, clear, and exact description.

The purpose of my invention is to provide a reliable adding-machine of exceedingly simple construction and which may be conveniently and expeditiously operated and applied directly to the columns of figures to be added, and, further, to provide the machine with an indicator which as the machine is moved down a column of figures to be added will be at the right or at the left, as desired, or which may be made to cover or conceal the last figure added.

Another purpose of the invention is to provide a machine of the character described which will be light, small, and may be readily used in account-books or on individual sheets of gures and which when in position will indicate the column being added, aswell as the next figure to be added in the column and which may be readily moved from one column to the'other.

A further purpose of the invention is to provide means for operating the machine by a single lever having movement with reference to a scale of iigures independent of the total-adding mechanism.

The invention consists in the novel construction aud combination of the several parts, as will be hereinafter' fully set forth, and pointed out in the claims.

Reference is lo be had to the accompanying drawings, forminga part of this speciiication, in which similar characters of reference iindicate corresponding parts in all the figures.

Figure 1 is a plan view of the adding-machine, illustrating its application to a sheet containing columns of igures to be added, three of the columns having been added, the machine being shown in position to commence the addition of the fourth or Iinal column. Fig. 2 is a transverse section taken practically on the line 2 2 of Fig. 1, and Fig. 3 is a longitndinal section taken practically on the line 3 3 of Fig. 1.

A represents a base, which is made as light as possible consistent with strength, and said base may be made of wood, aluminium, or other equivalent material. In the upper face of the said base a depression 10 is produced, as is shown bestin Fig. 1, and on this depressed surface 10 a scale Al appears, the divisionlines 11 of which extend transversely across the said depressed surface, as is also shown in Fig. l. These lines commence at a point near the right-hand end of the depressed surface 10 and extend to the left-hand end of said surface, and adjacent to'each line a number is produced, which numbers read from 1 to 9, the number 1 appearing at the initial or right-hand division-line 11 of the scale, and about centrally between the ends of the said scaled surface of the body A an indicating-nger12 extends from the lower edge of the said body, and this indicatingnger in the use of the machine may be brought over a figure in the column which has just been added or opposite a iigure to be added, either to the right or to the left of such figure.

In connection with the body A an addingwheel B is employed, mounted to revolve upon what may be termed the upper portion of the body at its outer face or upper face. This adding-wheel Bis provided upon its outer face with a circularlyarranged scale B', the divisions of which are numbered consecutively from 1 to 100, and at each division of the scale B on the addingwheel B a tooth 13 is peripherally formed. All these teeth incline in the same direction.

The addingwheel B is prevented from moving backward or is compelled to move in one direction only through the medium of a pawl 14, which engages with a tooth 13 on the adding- Wheel, and this pawl, which is preferably made of spring material or may be controlled by a spring, is secured at one end in a bearing 15, adjustably mounted, preferably, near the right-hand side of the body A at a point below the said addingwheel B, as is shown in Fig. 1.

The adding-wheel B is not shown mounted to turn directly on the upper face of the body A, but upon the upper face of a block or extension 16 from the said body, which is secured in any approved manner to the upper face of the body, and this block or extension 16 from the body A is made more or less cir- IOO cular, so that it will not extend beyond the toothed peripheral portion of the said adding-wheel B. In the under face of the eX- tension 16 of the bodya recess 17 is produced, (shown in Fig. 2,) and this recess eX- tends from the central portion of the said eX- tension 16 of the body to and through the lower edge of the said extension, the said recess 17 being more or less V-shaped and widest at its lower or outer end. The adding-wheel B is pivoted on the extension 16 of the body A by means of a suitable pivot-pin 18, which may be carried through the body, if desired, or may be secured in the body at its lower end in any desired manner. This pivot-pin 18 is likewise passed through an opening at the upper end of the operating-lever C, the upper portion of which lever extends in the said recess 17 and has movement therein. Therefore the upper end of the operating-lever C is pivoted centrally with respect to the adding-wheel B; but the operating-lever C is independent of the said adding-wheel. This operating-lever C extends over the scalesurface A' of the body A, as is also shown in Fig. 1, and preferably at the lower end of the said operating-lever C a handle C is pivoted, enabling the operator to move the operating-lever C over the scale A in a most convenient manner. The operating-lever C is guided in its movement by being passed beneath a guide-yoke 19, which is secured to the body A of the machine above the depressed scale surface A/ of the body. This operatinglever C is provided with a pointer 20 at its left-hand edge, where it moves over the said scale A' of the body, the outer edge of which pointer is straight, and in the operation of the machine the outer straight edge of this pointer 2O is brought in parallelism and is made to register with a division-line l1 of the scale A on the body, adjacent to which the figure appears which is to be added to a total by the operation of the adding-wheel B.

The adding-wheel B is given movement through the medium of a spring-dog 21, which dog is normally in engagement with one or the other of the peripheral teeth 13 on the adding-wheel, and preferably one end of the said spring-dog 2l is secured to the operating-lever C. As illustrated, this attachment is made by producing an upwardly-extending loop 22 in the said operating-lever C, through which the heel end of the dog 21 is passed and secu red, as isillustratedin Fig. 3. The adding-wheel B is turned by the operator, when so desired, through the medium oiI a knob 23, which extends from the upper face of the said adding-wheel, as is shown in Figs. 1 and 2.

At the right-hand side of the body A a shield 24 is secured, Which, as is shown in 1 and 2, extends upward at the righthand edge of the said body and then across the scale-section B of the adding-wheel B at the right-hand central portion of the said wheel, as is particularly shown in Fig. 1. The outer member of this shield may be termed a pointer7 member, and its lower edge is straight, so that it maybe brought in registry with any division-line in the scale B of the adding-wheel B, while its opposing edge is more or less inclined or beveled, so that a portion of the figure over which the pointer member of the shield extends is visible, enabling the said tigu re to be easily read.

An extension 25 is made from the left-hand side edge of the body, preferably opposite the shield 24, and on this extension 25 from the body theinuerend of thehandle26 is secured by means of a thumb-nut 27 or equivalent means.

In the operation of this machine the adding-wheel B is turned by hand until the number 100 is below the pointer member of the shield 2A. The adding-wheel being in this position, the machine is placed upon the book or sheet containing the columns of Iigures to be added, being so placed initially that the indicating-finger 12 at the bottom of the body will be either above the first gure in the units-column or at the right or the left hand side of such figure, and, further, before or after the machine has been thus placed in position the operating-lever C is carried to the right until its left-hand edge will be to the right of the initial division-line 11 of the scale A,which line is numbered 1. In adding a column of figures, as per the example shown in the drawings, the operating-lever C is iirst moved so that the left-hand edge of its pointer 2O will be brought in registry with the di- Vision-line marked on the scale A', as the first figure in the said units-column is the figure 2. The operating -lever is then moved to the right, preferably to an engagement with the right-hand end of the depression 10 on which the scale A is produced, and under this movement of the operatinglever C the dog 2l will have moved the addingwheel B a distance of two of its teeth 13, thus bringing the figure 2 beneath the pointer member of the shield 24E. As the next figure in the units-column is also 2, the operatinglever C is carried to the division line indicated by the figure 2 again, and is then carried once more to the right-hand end of the depression 10. thus causing the dog 2l to again move the adding-wheel B thedistance of two teeth and bringing the figure 4: on the scale B of said Wheel beneath the pointer member of the shield 24E. The next figure in the units-column to be added is 3. The operating-lever C is then carried across the scale A until the left-hand edge of the pointer 20 is brought in registry with the divisionline marker 3 on the scale A, and is then carried to the right-hand end ofthe depressed surface 10, u pon which said scale is produced, thereby causing the adding-wheel B to be moved the distance of three teeth, bringing the figure 7 below the pointer member of the shield 24-, The last figure shown in the IIO IZO

units-column of the example is 6. Therefore the operating-lever C is again moved over the scale A until the left-hand edge of its pointer 20 isin registry with the divisionline 11 on the scale A', designated as 6, whereupon the operatinglever is carried again to the right-hand end of the depressed section 10, on which the scale A is produced, thereby causing the dog 21 to revolve the adding-wheel B the distance of six teeth, causing the figure 13 to be brought beneath the indicating member of the said shield 24. This figure 18 will designate the total of the addition ofthe figures in the units-column. The figure 3 of the total 18 is then placed below the units-column on the second line to designate the unit of the total, and the ligure 1 is placed beneath the lowest figure in the tens-column. The operator will now reverse the adding-wheel B to bring it again in such position that the number 100 will be beneath the indicating member of the shield 24, and the machine is then shifted in a manner to bring the indicating-linger 12 at the bottom of the body over the upper portion ofthe tens-column or the next column to be added, or to the right or to the left of the ilrst figure in such column,and this column is then added in the same manner as has been described with reference to the units-column. Thus each column of ligures is added, and as the total of each column is obtained upon the addingwheel B the right-hand ligure of said totalis set down beneath the column added,while theletthand figure of the total, or the figure to be carried, is set down beneath the last figure of the next column to be added, and as the total of each column is obtained and the results set down, as stated, the adding-wheel B is turned to bring the numeral 100 beneath the pointer member of the shield 24.

When the machine is operated, itis held by the left hand by means of the handle 26, and the operating-lever is manipulated by the right hand.

Having thus described my invention, l claim as new and desire to secure by Letters Patent- 1.
