To all whmn z t 11w concern/.

Be it known that 1, CHARLES FREDERICK LAGANKE, a citizen of the United States, residing at Harrisburg, in the county of Dauphin and State of Pennsylvania, have invented a new and useful Combined Type-Writing and Calculating Machine, of which the following is a specification.

This invention relates to a combined typewriting and calculating machine of that particular character in which a book type-writer 'is equipped with one or more computing devices or registers and with operating connections whereby the numeral-keys, besides performing their ordinary functions in connection with the printing ofdigits, also efiect the operation of the computing device or computing devices to compute the total or totals of numbers printed in one or more columns.

The primar objects of the present invention' are as fo lows: First, to provide means for positively retaining the transfer-do s of the computing device in engagement with the number-whee s thereof while the machine is operating in the column to be computed; sec- 0nd, to provide the operating connections of the computing device with a dust case or guard and to equip. the computing device with a reading-glass supported in a convenient position at some distance fromthe digits exhibited at the sight-opening to magnify said digits and facilitate the reading thereof by the operator.

To the accomplishment of these objects the preferred embodiment of the invention resides in the construction and arran ement of parts to be hereinafter described, i lustrated in the accompanying drawings, and defined in the ap ended claims.

In sai drawings, Figure 1 is a perspective view of an Elliott-Fisher billin andaadding machine equipped in' accor ance with my invention. Fig. 2 is a plan'view of the machine. Fig. 3 is a sectional elevation, on a somewhat en arged scale, of the computing device, a portion of its operating mechanism, and certain associated parts. Fig. 4 is a 1ongitudinal sectional View of the dust guard or case. Fig. 5 is a transverse section of the same, andFig. 6 is a detail'view of the device for insurin the engagement of the transferdogs with t e number-wheels, and Fig. 7 is a sectional view of the upper portion of the ma chine.

Each part is indicated by the same numeral throughout the views.

The Elliott-Fisher billing and adding ma chine, well known in the art, includes a billing-platen 1, adapted to support the paper and carrying a machine-frame 2, movable lengthwise of the platen for line-spacing and supporting a traveling carriage 3, which sustains the key-operated type-writing. mechanism and is movable transversely of the platen for letter-spacing.

At the rear side of the machine-frame 2 is supported a guide-bar 4, upon which is adjustably mounted a computing device or reg ister 5. Within the casing of the computing device is mounted an al-ined series of denominational members or number-wheels 6, associated with transfer mechanism which when any wheel has completed nine increments of independent movement will be automatically brought into action to impart a single increment of movement to the wheel of next highest order. This carrying mechanism includes a series of transfer-levers 7, arranged to be thrown down or depressed by projec tions 8 on the number-wheels.

Mounted in each transfer-lever is a pivoted carrying-dog 9, which engages the next number-wheel to the left of the one which moves the transfer-lever. Thus when a wheel is moving from 39 to 0 the projection thereon engages and swings a transfer-lever 7 to cause the carrying-dog 9 of said lever to advance the next adjacent number-wheel of higher order. These features of the computing device are in common use and appear to require no further description for the purpose of the present disclosure.

The number-Wheels 6 are operated by a master-wheel 10, which is mounted on and moves With the carriage 3, being thus pre sented to successive number-wheels of the computing device as the printing-point of the type-writing machine advances to successive denominational. ositions in the column being totalized. he master-wheel 10 is operated from the numeral-keys of the type writer by a series of operating connections, which may bedesignated as a whole by 11. These connections need not be specifically described; but it'may be stated that, except for the devices which couple said connections to the keys, they are located above the cover-- late 12 of the casing of the carriage 3, est shown in Fig. 1.

Extending rearwardly from the carriage 3 is a transfer-lever-depressing arm 13, which slightly depresses the transfer-levers to prevent clashing when one or more numberwheels are stopped in the 9 position.

The entire structure described being com- 111011 to the Elliott-Fisher billin and adding machine of connnerce is only disclosed herein in a general way in order that. the utility of the structural features to be described, and which constitute the present invention, may be fully understood.

The transfer-dogs 9 are ounted in the transfer-levers 7, as heretofore stated, being pivoted at their upper ends, asindicated at 9*. In accordance with my present invention each dog is provided with a tailpiece 14, extended upwardly from its upper end and longitudinally curved to present it in concentric relation with the axis of the transfer-lever. Cooperating with the tailpieces 14 is what may be termed a "transfer-dog-retaining bar 15, having beveled ends 16 (see Fig. 6) and preferably carried by the rear end of the lever-depressing arm 13. As the carriage advances the bar 15 travels across the series of tailpieces 14 of the transfer-dog 9, the relation of the parts being shown at Fi It will be noted that the lower cm of each transfer-dog extends over a tooth of a num her-wheel and that in order for the dog to disengage itself its lower end must swing rearwardly. his movement of the dog is prevented by reason of the fact that the bar .15 obstructs the forward movement of the tailpiece 14, and therefore after the bar has once engaged a tailpiece orarrived in a position opposite the same the dog is incapable of such movement upon its own axis as would permitits disengagement from the number-wheel while the transfer-lever occupies its elevated or normal position. It should be particularly noted, however, that the bar 15 does not prevent such movement of the transfer lever and dog as is necessary to a carrying operation. Such movement of the parts is ermitted by reason of the fact that the tai piece 14 is concentric with the axis of the transfer-lever, and therefore as the lever moves down in the act'of carrying the tailpiece of its dog simply moves longitudinally in an arcuate path, the lower end of the dog and the engaged tooth of the numberwheel gradually separating by reason'of the divergence of their paths of movement. The

bar 15 not only prevents accidental disengagement of the transfer-dogs from the wheels, but actually serves to throw into more effective engagement a dog which may have moved bac more or less from the national wheels that actually carry and display the numbers or digits it not essential that these members possess either of these characteristics, since the invention resides in the cooperative relation between these members arranged in different denominational positions and the various elements specified regardless of the particular form of the members and equally regardless of whether or not they directly carry and display the digits, it being common in this art to employ denomimembers of various forms and equally common to display the digits upon carriers cooperatively related to the denomi national :members with which the carrying I mechanism coacts.

In addition to the mechanism just described for insuring the engagement of the transferdogs and number-ivhccls while the masterwheel located opposite the register the present invention also contcn'iplatcs the provision of a dust guard or case 17 for the operating connections of the con'iputing device. This case comprises a pair of pen-end frames 1254, rising from the covenplate 12 adjacent to the opposite ends thereof, celluloid or other trans parent walls 19 closing the end frames, and an approximately semicylindrical transparent wall 20 extending between the end frames and inclosing the operating connections of the computing device.

Each of the end frames 1.8 include an inner member 18 and an outer member 18, the inner member being comparatively still and the outer member preferably formed of sheet metal and having a flange 18 overhanging the inner member and a foot-flange 18, which screwed or otherwise secured to the cover-plate 12. Each end wall 19 has its edges clamped securely between the inner and outer members of an end frame, said "members being firmly connected by screws 21 or other retaining devices. The c iposite ends of the wall 20 are securely clamped against the outer edges of the inner frame members lS -by the overhringing, llanges 18 of the adjacent outer members, hs clearly shown in Fig. 4.

In order to secure the greatest possible stability of this dust case or guard, and more particularly to prevent spreading of the end frames thereof, said frames are provided with depending lugs 22, screwed or ot erwise secured to the endbrackets 23-of the com uting-device connections. The rear edge 0 the wall. is secured to stiffening-plates 24, notched to accommodate projecting portions of the operating connections orthe mount in s thereof-and having lugs 25 screwed or otherwise secured to the cover-plate 12 or other fixed part, as shown in- Fig. 4. The wall 20 of thedust-case is, also provided with openings 26, through which project the 1naster-wheel 10 and other parts which necessarily engage and cooperate with elements of the computing device. The front edge of the wall 20 is secured, as by screws 27,110 brackets 28, rigid with the cover-plate 12. (See Fig. 5.) The walls 19 and 20 of the dust case or guard are preferably, though not necessarily, transparent, as already stated, and while glass, mica, or other suitable material may be used I contemplate forming the walls of celluloid or some similar compound.

' By providing the operating connections with a guard or case of the character described the mechanism is kept clean and free from dust, although constantly open to view and readily accessible for repair.

Another feature of the present invention resides in the provision of a reading-glass 29 mounted in a frame 30, secured at the upper end of a standard 31, having a foot 32 disposed at an angle to the standard and resting on the top of the com utin device 5. The foot 32 is provided Wit a bi urcated rear end 33, which engages the shank of a headed screw 34, screwed into the computing-device casing, and in advance of its bifurcated end the foot is provided with a longitudinal slot 35, having an enlarged rear end designed to permit the passage of the head of a second screw 36. By this arrangement it is possible to attach the mounting of the reading-glass to the casing of the computing device or to effect its detachment therefrom without removing the screws, it being simply necessary to move the foot forwardly from the position shown in Fig. 2 in order to bring the head of the screw 36 in coincidence with the enlarged end of the slot when it is desired to remove the mounting or to reverse this opera tion in attaching the reading-glass to the easl vhen in proper position, the lass 29 is held in an elevated position above t e sight-opening 37 of the computing device and is given a pears at this time to be preferable, I desire to reserve the right to effect such changes, modifications, and variations thereof as may come fairly Within the scope of the protection prayed.
