To all whom alt may concem:
Be t known that I, Fama TsINns, engineer, subject. of the Emperor of Germany. rc-
siding at Brunswick, Duchy of Brunswick, Empire of Germany, have invented certain new and useful lmprovements in Calculating-Machines, of which the following is a specification.
My invention relates to improvements in calculating machines of the class illustrated in the U. S. Patent Nr. &30,066 granted to \Vi1liam Kttner and in the U. S. Patent Nr. 823375, granted to me June 12, 1906. In the said machines the adjustment of the values is efl'ected on toothed wheels having varying numbers of their teeth adjusted in operative positions by means of cam disks connected with each of said tootled wheels. The cam disks are turned by means of small handles which project from the peripheries of the disksthrough slots provided in the machine casing. In machines of this class levers have been provided on the adjusting mechanism by means of which the cam disks are rotated so as to force the proper number of radial teeth of the adjusting Wheels into or out of operative position, as described in the U. S. Patent Nr. 843506, granted to me February 5, 1907. As described in this patcnt, the levers en -age pin projections provided on the cam isk whereby the latter are carried along.
Now, more particularly, my invention relates to improvements in machines of the last named type, and its object is to provide a printing mechanism, whercby the value adjusted on the toothed wheels is printed by rotating the crank of the machine.
For the purpose of illustrating the invention, I have shown an example of the same in the accompanying drawing, in which the same 'letters of reference have been used in all the views to indicate corresponding parts. i In said d'awing,-Fig1re 1, is a vertical cross-section of a machine embodying the invention, and Fig. 2, is a partial plan of Fig. 1` with the upper casing wall removed for the purpose of showing themechanism of the machine.
On a longitudinal shaft d mounted iii the lateral uprights of the casing of the machine a plurality of adjusting wheels 7' (Fig. 2) are located adapted to be rotated from the main crank j by -means of gear wheels j The adjustin wheels j are fixed to a sleeve d mounte to rotate on the shaft (l,'
as shown in Fig. 2, and the gear j is Secured to the shutt c of main crank j, while the gear j is fixed to the sleeve 5 Each of the disks 7' has nine radially movable ratchet teeth j* adapted to bc brought into or out of operative position by means of concentrically arranged cam disks t' adapted to be rotated by means of levers l carried by disks 70 arranged on the shaft adjacent to the cam disks, which levers extend through slots ?L i of the cover 3 of the casing and engage,
through a pivotal elbow lever h the cam dsks b, so as to carry the same along when rotated. The wheels or dsks j are circular n form and correspond n dameter with the cam disks b by which they are concealed in Fig. 1, butthe arrangement of this mechanism appears clearly from Fi 2. The wheels ;i when rotated transmit t eir movement to the counting wheels 'n of the main counting n'echanism by means of spur gears n n which uechanism' is mountcd on a carriage n adapted to be shifted parallel with the shaft d, so that the teeth 7' of the adjusting wheels j, if desired, may act directly on the spur gears n of higher value places. The counting nechanisn is also provided With carryng mechanisn, consistiug, in 'the present example,
of a pivoted hammer-shaped lever w o erated by a pin n* of the countin Wherehy, by a beveled face w o? the lever u', pivoted tooth j of the adjusting wheel j is brought into enga ement with the gear wheel n Two pivotateeth j and two beveled faces w are provided to accommodate a right and left hand rotation of the machine crank 4 The disks h* of the levers h have'teeth k arranged about part of their circumferences, which teeth are in engagement'with spur gears :u disposed in the upper part of the machine and roviding a counting mechanism a) for indicating the ad'ustment of the levers h and thereby that o the adjusting The figures of the counting Wheels wheels j. are visible through sight openings provided in. the curved cover y of the casing of the machine. By' means of beveled faces j provided on the adjusting-wheels j the carrying Ievers w are brought back into their positons of rest.
Now, in order to record the values adjusted on the adjusting wheelsfor each operation of the machine, I provide a printing or Whee n,
mechanism, which in the example illustrated I 55 drawing.
consists of the following elements: At the side bf the adjusting mechanism described, on a comnon axis parallel with the axis d, I provide a type wheel or sector for each of the adjusting wheels, which type wheels or sectors are operated by the levers arranged to rotate the cam disks cont'ollin the adjustment of.the movable teeth oi the adusting wheels in their operative positions.
The type wheels form part 'of a printing 'mechansm adapted to print values determned by the adjustnent of the adjusting wheels when the crank is rotated. In the present example, the type carrier for each of the adjustng wheels consists of a sector t mounted on a shaft e parallel to the axis d of the adjusting wheels, and having teeth t meshing with teeth a of the lever-disk h* ,located sidewise of the cam disk b whereby when rotating the lever k in the direction ot the arrow, the type carrier is moved a number of types equal to the number of the teeth of the adjusting wheel j thrown into operative position. Opposite the type carrer, I provide a fprintng platen q adapted to press a web o paper z' supplied from a drum f against the type carrier t and thereby to efi'ect printing. The platen is shown as being actuated from the sleeve d of the setting nechanism, and for this purpose a disk g (Fig. 2) is mounted upon the sleeve ti' at the outside of the casing, said disk carrying a crank-pin g which is connected by means of a connecting rod 0 with the crankpin 17 of a disk 13 located at the outside of the casing and fixed on a shaft 77 In Fig. 2 the disk p is covered by the disk g and the connecting rod o is omitted for the sake of clearness. Then the disk g is rotated with 40 its sleeve d the rod 0, which has a rocking and longitudinally sliding movement on a stationary pivot m, turns the disk p and thereby rotatesthe shaft p Upon this latter shaft i's mounted a cam p (see Fig. 1)
from which the printing platen g is operated. The paper feed mechanism s s is also shown as being actuated from the cam ;0. A ratchet wheel 'u is fixed upon the shaft 8 of one of the feed rollers s and a pawl 12 is connected with the cam p by means of a crank-pin '72 as shown in Fig. 1. The parts.
` returned to its normal position by the lever h at the end of the rotation of the crank. Means for throwing the type carrier in or out of operation, or locking means for con- 4 trolling the same before or during the operation of the crak, or special means to'move the same back into its normal position, such as springs or weights used in other devices of a similar character, are not required.
I claim:
1. In a calculating machine, the combination of a crank operated registering mechanism embodying a rotatable adjusting disk having indvidually movable teeth, means to adjust said teeth in operative position, and recording nechanisn 'set directly by said neans and comprising shiftable printing type normally imnovable by the rotation of the machine crank.
2. In a calculating machine, the combination of registering mechanism, a lever to set the same having a toothed segment, printing nechanism embodying a toothed type-carrying segment meshing with said first named segnent, and an automatically operated platen.
3. In a calculating machine, the combination of registering nechanism, a setting lever, a type carrier operated automatically by said lever, and a platen operated automatically by the registering nechanism.
4. In a calculating machine, the combination of registering mechanism,`a setting lever, a type carrier operated automatically by said lever, a platen operated automatically by the registcring mechanism, and a. paper feeding device also operated by said registering mechanism.
5. In a calculating machine, the combination of registering mechanism embodying a 'otary sleeve, a setting device, a type carrier operated by the setting device, a platen, a platen Operating shaft, and an operative connection between said sleeve and said platen shaft by which the latter is actuated.
6. In a ealculating machine, the combination of registering mechanism embodying a rotatable disk having a plurality of mova le teeth, a can to adjust a definite number of said teeth in operative position, a separate lever to operate said cam, and printing mechanism automatically operated by direct engagement with said lever.
7.
