Specification of Letters Patent.
Patented July 29, 1913.
Application led March 5, 1913. Serial No. 751015.
To all 'whom it may concern.'
Be it known that I, ALnxANnnR CoNNio, a subject of the King of lt-aly, residing at Buenos Aires, Argentina, have invented certain new and useful Improvements in Calculating-Machines, of which the following` a specification,
This inventonrelates to improvements in A calculating machines ada ted to perform the operations of multip ication, division, etc. Y
The especial ob]ects of my present invention are t-o produce a machine of the character stated that can be economicallyT manufactured and easily operated, and that will perform its functions accurately and quickly. A further object of my invention is to provide a tabulated or scaled ribbon asan elementv of my calculating machine, which will be immune to thermal and humid atmospheric conditions, thus maintaining a element of my machine.
Referring to the details of the drawing, 4 represents a metal case which may be of any suitable shape, size or material, to contain and furnish support for the operative mechanism. In the top of the case is an `opening surrounded by a grooved frame into which is fitted a glass plate 25 through which theribbons may be viewed without exposing the latter.
5 repres-ents a standard which is secured by bolts 5a to the bottom of the case at one 'side of the latter, and is formed with vertical extensionsA 5, .5", 5h, and with horizontal arms 5c in which slots 5g are provided. On the'op-posite side of thecase is mounted astandard 6, which corresponds in shape to its complementary standard 5, but is slidable instead of being fixed.,V The standard 6 has slotted "arms 6 ,which correspond to the arms 5, and is provided with beveled feet 6c which slidably engage the'rabbeted plates 26 which are screwed to the bottoni ofthe case. It also has vertical extensions.corresponding to the extensions 5, 5", and 5 of the standard L 7, 7 represent reels or spools which are mounted on rotatable stub vspindles projecting inwardly from the vertical extensions 5", 5", etc., of the standards 5 and (3. The end ianges or rims of these spools are parallel and projectA a considerable distance from the hubs so as to furnish guides for the ribbons which they are designed to carry.
8 represents boxes which are fixed to the standards 5--6 concentric with the spindles 7b, and house coil springs 9, one end ofwhich is secured to said spindles and the other to the peripheral wall of the box. The springs in thc boxes at one end of the machine are so wound that 'a constant tension is exerted on all of the spindles regardless of the direction of their rotation, thus subjecting the ribbons which are wound and unwound from said spools to uniform traction of pull.,
10, 10 represent the ribbon elements of my machine. These are made of superposed strips of Celluloid and silk tissue secured together by a suitable adhesive so as-to withstand t-he action of the atmospheric heat and humidity. These ribbons have appropriate scales or tables as 10b indicated on'their celluloidfaces, the scale on the ribbon 10 bearing a mathematically ired relation to the scale on the ribbon 10, as in calculating devices of a similar character. The ends of the ribbons are secured respectively to the hubs of the spools 7, 7, and the ribbons run over rollers l1, 11, which are mounted on shafts 11d, 11c respectively. The inner ends of the rollers 11 are beveled as at 11", and the corresponding ends of theQollers 11 are countersunk or recessed as shown by dotted lines 11 n to receive said beveled ends and thus provide frictional engagement between the opposed rollers. The rollers 1l are formed with boxes to receive the shafts 11, as shown by dotted lines Fig. 2.1 On the outer ends of.
the shafts 11d, 11 are pinions 12, 12, which mesh with and are drlven by gears 13, 13,
respectively, which gears are mounted on shafts 14, 14 suitably journaled in the standards 5, and 6. Oii the shaft 14 is a crank 15 having a handle'l on itsfree end, and on the shaft 14 is a similar crank 15 having handle 16a. Idlers 17, 17a are mounted on spindles 18, 19 mounted in the slots 5g in the standards 5 and 6, and their faces are held in frictional engagement with the ribbons 10, 102L by blocks 23 adjustable by screws 20 and lock Ynuts 21, in a well-knownmanner. The spindles 19v enter boxes 19a inthe idler rollers 17 with a sliding lit.
-24 represents a plate arranged below the glass 25 and forming an opaque backin for the ribbons to facilitate the reading o the figures on the latter, through the glass 25. Across the center of the glass 25 is a line or work 25 which serves as a guide in setting the ribbons for desired calculations.
As a means of shifting the standard 6 with its members, I provide a lever which is pivoted on a stud 31 in the bottom of the vcasing and has a handle 32 at its free end.
The other end of this lever is connected at 29 with a link 28 which is connected at 28a with a lug 27 extending inwardly from the frame 6. A movement of the free end of the lever in the direction indicated by the arrow will draw the standard inwardly thus bringing into frictional engagement the opposed rollers 11, llnand 17, 17, whereby rotative movement imparted to the rollers in one standard will be communicated to the opposite rollers in the other standard. To eil'ect the sepa-ration of the opposed automatically, I provide springs 27a secured to the bottom of the casing in thpthof the standard 6 and so arranged that the-springs will be compressed when the standard is moved inwardly by the lever 30 as described. One of these springs is shown at the left hand of Fig. 1, and it will be understood that the plthe is correspondingly placed at the right l 5" and v6h represent lubricating tubes vious that by operating the cranks 15, 15a',
the ribbons l0, 1()a will'be driven independently of each other through the instrumentality of the gears and rollers described, and
that Vwhen the opposite rollers are brought into rictional engagement the ribbons will move in unison. v
My machine is a mechanical adaptation of the well known principles used in logarithms, and the manner in which its calculating operations are carried out need not therefore be set forth herein. appearing on the' ribbons will be cordinated to produce the desired results when the ribbons have been given their proper relative adjustments and then operated 1n the manner described. A
Having thus described my invention, I claim In a calculating machine, a case, the standards supported in said case, a pair of spools and a pair of rollers rotatably mounted on each of said standards, the rollers on one standard and adapted to frictionally engage eachV other, ribbons having cordinated scales, mounted on said spools and rollers, means for driving the rollers on each standard, and means for shifting' one of the standards whereby its rollers will be brought into engagement with the rollers on the complementary standard.
In testimony whereof I ailx my signature in the presence of two witnesses.
