W, T, RAY, CAL CULATING MACHINE, 1,410,507. APPLICATION FILED AN, 27, 1917. Patented Mar. 21, 1922. 3vuov to Aa/zer ZTZ(z/ * * 22%22 UNITEDwALTERSTATES PATENT OFFICE. T. RAY, OF VIRGINIA BEACH, VIRGINIA. 1,410,507. CALCULATING MACHINE. Specification of Letters Patent, Patented Mar. 21, 1922. Original application filed Novemberuary 19, 1915, serial No. 62,264. Divided and this application filed Jan 27, 1917. Serial No. 144,801. ". . . . ." To all usion, it may concern: 4. through which additions are performed by 55 Be it known that I, WALTER T. RAY, a motion in one direction and subtractions by citizen of the United States, and a resident in the reverse direction, all of which of Virginia Beach, in the county of Princess isnotion well understood and forms no part of the Anne, and State of Virginia, have invented present invention. The number of openings 3 certain new and useful improvements in and disks 4 employed correspond to the de 60 Calculating Machines, of which the follow sired number of columns for which the ma ing is a specification. . .. . chine is designed; and the said member 4 is ... The invention relates to calculating ma herein described and shown in the nature of 10 chines, and may be embodied, for example, a rotary disk suitably mounted upon a hub in non-listing adding and subtracting ma 5, being visible in part through a corre 65 chines, in which a rotatable or a reversible sponding opening 3 in the top of the casing. computer or indicator member is acted upon Further apertures 6 are provided in said by a suitable stylus, pencil or the like to casing at the top at convenient points near 5 actuate the computing mechanism. It will each of the openings 3 and through whichi ise understood that, where such reversal of the result may be read. A notch 7, more 70 the motion or rotation of an indicator dial over, is provided conveniently, for example, or member is effected, the means at the end in the lowermost portion of the circumfer. or limiting position for determining the ence of each of the openings 3 and is ar 20 proper extent of movement for the desired ranged radially with respect to depressions number to be added or subtracted intist be 8 of the upper surface of said disk. The 75 such as to pi'operly accommodate the actuat said depressions are arranged radially on a ing stylus, which is of appreciable width, or disk so as to be readily accessible through else it must have a negative value. A pro an opening 3 for engagement with a suitable jection or finger is, therefore, not suitable operating tool, such as a pencil, stylus or for this purpose: and it is the object of the the like for the purpose of moving or ro 80 present invention to determine this position the disk. Notch 7 will act as a suit accurately aid positively by providing a tating able stop for positively determining the cal suitable notch or slot into which the actuat culating position of the tool or stylus in 30 ing tool naturally falls and positively en direction of its movement, falling gages with. A further object of the inven either naturally therein and engaging positively 85 tion is to enable the Zero position to be therewith and allowing of a perfectly free quickly and readily obtained in resetting rotation or movement of a said member 4 the mechanism and with practically no men in either direction. w 35 tal effort on the part of the operator. For convenience in resetting the number 90 The accompanying drawing illustrates the wheels to the “0” position, a particular de invention, for example as embodied in con pression 9 of each wheel is made of greater nection with an adding and subtracting ma length than the remaining ones; and is so chine of the type set forth in a co-pending placed that when it is alined with the notch 40 application filed by me the 19th day of No 7, the number “0” is displayed through the vember, 1915, Serial No. 62264, and of which corresponding aperture 6. Thus, any col 95 the present application is a division. umn may be quickly reset to the “0” posi Referring to the drawing, 1 designates the tion without any mental effort on the part base plate upon which the mechanism is of the operator, simply by inserting the op 45 mounted, and 2 a suitable casing secured erating tool into the longest depression 9, thereto and provided with a plurality of wherever it may be located, and rotating 100 openings 3 in its upper surface, the same the wheel in the shortest way-in either di being herein described and shown as circu i'ection-to the notch 7. As herein set forth lar. The calculating mechanism (not and shown in the drawing, each number. 50 shown) may be of any well-known or special wheel is provided with ten depressions as construction, for example as set forth in the machine is designed for use with the 05 aforesaid co-pending application, Serial No. the decimal systein; but the invention is not 62264, and is provided with reversible, mov restricted to this particular system, being able computer members or indicator disks equaliy applicable to other systems, as will
