. ADIDING RECORDING MACHINE.
specifieation of Letters Patent.
To all whom it may concern Be it known that I, Jorm Macros, a citizen of the United States, Tesidlng at Poplar Bluff, county of Butler, and State of Missouri, have inentcd a new and useful Adding and Recording-Machine, of whlch the following is a specification.
This invention relates to recording ma chines, and more particularly to the paper feeding mechanism and, while particularly. adapted to adding and recording machines,
its capabilities are not at all restricted and it may be combined and used on other types of recording machines.
An object of the invention is to provide, in combination with the platen, a paper roll arranged to supply paper to the platen, and
7 another roll to take up' the paper passing from the platen, with provisions for effecting rotation of the last-named roll.
In the drawings in which I have illus'- trated my invention applied and adapted to a well known adding machine Figure 1 is an elevation with the operating mechanism of the adding machine shown in course of operation. Fig. 2 is an enlarged sectionah view showing the devices for operating the roll for taking up the paper, passing from the platen. Fig. 3 1s a front elevation, the inclosure for the operating mechanism being in section. Fig. sis a top or plan view of the roll supports and operating.-appliances. Fig. 5 is a View illustrating the operating devices. ready for movement to rotate the paper roll: Fig, 6 is a sectional view of the ratchet wheel which controls .the roll for,
, taking up the paper. Figs. 7 and 8 show columns or lists of items ornumbers printed on paper fedfrom'mypaper feeding mechanism.
- link D whose rear end is connected to a plate El -which is pivoted on a shaft F. 'In idle position the platef'E is elevated, asshown forwardlythe plate E mounted upon with a bearing 5 inthe The-machine on which I have illustrated in Fig. 2, but when the handle B is drawn is swung downwardly and forwardly, as shown in Fig. 1. This operation of the handle B also causes the type-carriers to move and produce the necessary records on paper passing around the platen.
The support for the paper roll comprises two substantially vertical arms 1 removably Bearings are formed near the upper extremities of the-vertical portions of the arms 1 and in one of said bearings a hub 2 (Fig. 6) is mounted'and on its outer portion supports a ratchet wheel shaft 4 is arranged to-p'ass through the hub the case of the machine.
3. An axial rod or" Patented Mar. 16, 1915.
2 and wheel '3 to secure threaded engagement other vertical arm 1. Therod 4 supports a blade or spline 6 which passes into and through a groove 7 in the hub 2 thereby locking said hub and the ratchet wheel 3 upon the said shaft. The
paper spool 8 is mounted upon the .rod or shaft 4 between the vertical arms by being looked upon the shaft by the blade or spline 6, which passes through a slot or groove in the spool. The outer end of the rod or shaft 4 ispro'vided with a knob 9, whereby said shaft may be manually engaged for .adjustment or release.
' The upper portions of the arms 1 extend obliquely upwardly and rearwardly, said oblique of the oblique portions. 10 are provided with bearings ll'arranged to raise and support a rod or shaft 12 which is a duplicate of the rod or shaft 4 previously described, being provided with a ,bladeor portions being indicated by 10. The rear extremities spline 13 corresponding to Lheflhlade orspline 6 and with knob 14, similar to and for the. same purpose as the knob 9. A
spring 15 is arranged to press against one end ,of the spool mounted on the rod or 'shaft l2 so as to act as abrake therefor and prevent excess movement of the paper-passing from therear spool to the platen passing under and in front of the platen and-upwardly to the spool 8 mounted on the rod or shaft 4. Arms 6 extending forwardly from the arms 1 form.'a space in which the paper passes and constitutes guides for the paper passingto the platen. Rotation" of. the
platen'will ,drawthepaper from the supply spool, but it may be necessary to rotate up the paper passing across the face-of the yielding th spool 8 by special mechanism, one form of which I will now describe- A'plate 17 swings from; the hub 2; between the ratchet wheel 3 and the Supporting arm 1. A pawl 18 is pivoted to. theouter surface of the plate 17 and is actuated into engagement with the ratchet wheel 3 by a spring 19. A. lever 20 is supported on a pivot 21 and extends in front of a'projecs tion 22 on the plate 17. An arm 23 is also supported on the pivot 21 and extends behind the projection connection 2% with the lever 20 and is connected to said lever 20 by a spring 25 which is effective to hold the-said arm and lever in position shown in Figs. 2 and 5. A spring 26 connects the upper end of the lever 20' with the arm 1 actuating said lever rearwardly. The lower end of the lever 20 extends through a slot .27 in the case of the machine and carries a roller 28 which, in idle position, is in contact with the upper edge ofthe plate E, as illustrated in Fig. 2. When the'handle B is operated forwardly, as shown in Fig. 1, the plate E is moved downwardly and'forwardly away from the roller 28 permitting the spring 26 to retract and causing the lever 20 to raise the plate 17 and the pawl 18 to engage said pawl'at another point on the ratchet wheel 3. After the handlezB reaches the end of its for ward movement and is released, and after the recording type on the type-carriers A have printed uponthe paper passing in front of the platen C, the said type-carriers and handle and also plate E return to their idle or rest positions, the plate E again engaging the roller 28 and moving the lower end ofthc leverv 20 rearwardly and the upper end of said lever forwardly inopposition to the tension of the spring 28. -The spring 25 between the lever 20 and the arm 23 to move the plate 17 and .the pawl 18 forwardly thereby rotatingv the rod or shaft 4 and the spool 8 mounted thereon effectively to take platen. The movement of the parts efl'ect- I ingrotation of the spool 8 is timed so that the spool will be rotated the proper distance after each movement of the paper, so. asto wind on said spool and hold under tension the. paper leaving the,platen. The fork or bifurcation formed bythe lever 20- and the arm 23 yields to the tension of the paper when the spool 8 becomes filled so that the paper will not be torntherebyj nor drawn too rapidly across the platen.
The operati,gfdevicesfor' the spool 8 are inclosed within a case 29 attached to the ,arm 1 supporting said devices, thereby shielding and protecting thcmfrom accidental injury or displacement or from gathering accumulations of dust, etc. i I
After the front spool 8. becomes filled it 22 and has pih-in-slot said lever, a lever for moving the pawl in constitutes a yielding. connection may be removed and placed upon the rear rod or shaft 12 and an empty spool placed upon the rod or shaft l. The paper can then be fed across the platen again so as to receive a second column of items, as shown in Fig. 8, and wound on to the newly located empty spool. The second column will be a suitable distance from the first column and inverted with respect to the first column, or may be printed on the opposite side of'the "1 paper.
Mechanism of this character is found useful upon adding and listing; machines when it is desired to preserve the paper containing the lists, and also when it is desired to list more than one column upon the paper,.
