CARRYING MECHANISM;

Specification of Letters Patent. 1

Patented Sept. 23, 1913.

Application filed April 1912. Serial No. 699,732.

To all whom it may concern:

Be it known that I,- ARTHtm 'Han'rsorr, a citizen of the German Empire, and a resident of Linden, Hudson county, New Jersey, have invented certain new and useful I, Improvements in Carrying Mechanisms, of

my improved counting drum particularly tooth operating slide.

which the following is a specification.

This invention relates to improvements in carrying mechanisms for calculating machines.

The object of the invention is to simplify the construction and design of certain parts or elements of the carrying mechanism and to provide means for a better and more positive operation than is possible with other constructions known to the art.

in the drawings illustrating my invention and accompanying this specification l igure 1 is a partial plan view of a calculating machine illustrating my invention, Fig. 2 is a side elevation of the parts'shown in Fig 1. Fig.3 a transverse sectional view. F 4:, 5, 6 and 7 are detail views of illustrating the movable tooth carried thereon. F 1g. 8 illustrates a certain oscillating circular lever for operating the movable tootln Fig. 9 illustrates in detail the mov-,

able tooth. Fig. 10 illustrates in detail the cover plate for the tooth. Fig. 11 shows the Fig. 12 shows the tooth operating lever and cam. Fig. 13 illustrates steps in the operation of my de vice. Fig. 14 is a detail view of the locking lever. Fig. 15 is an enlarged view of the counting-diaun and its associated parts ineluding the movable tooth and Fig. 16 is a plan view showing how the movable tooth' -is supported and operated on a toothless with nine teeth.

counting drum.

. Referring to Figs. 1, 2 and 3 the numeral 1 represents the framework in which the counting

drums

2, 2 are journaled in known manncrz- Ilach drum is as usual provided 3, 3, are the tens wheels slidably supported on the "quare shafts t which also carry the locking wheels 5 which cooperate with the locking cams G of the counting drums.

7, '7 are the usual number wheels each of" which 1s 1".!'()'\'ltl0(l wlth the carrying arm 8.

9 is the counting drum operating shaftwhich is rotated from the shaft 10 in the usual manner by a handle, not shown. I

()no object of my invention is to provide a more positive drive of the counting drums from the shaft 9 than is possible by means .of individual gearing. To this end I drive only the two

end shafts

11, 11 by gears 12,

12 from the driving shaft 9-, and on the innerend ,of each counting-drum shaft 11 I mount a crank 13, and all of the latter are connected by a sin l'e connectin rod 14. By this means all tIi operated positively at one and the same time and'I dispense with a great many gears which otherwise would be needed for this purpose. The positive driving connection between the counting drums prevents all lost motion 'andis very advantageous and simple to build.

Another object of my invention is to eliminate the separate tens transferring tooth as an independent se arate element mounted and operated away rom the count e counting rums are ing drums, which necessitates a complicated for the tens transferring means. a

In this instance I mount the tens transferring tooth directly onthe counting drums as a'movable tooth thereon and provide a suitable operating mechanismtherefor.

Referring to the Figs. 4 to 15 it will be seen that the counting drum '2 iscut out to form

sockets

15, 15 in which are secured

pins

16,16, Fig. 5. On the latter are pivoted circular swinging'levers 17, 17.- Each lever hasan aperture 18 to fit over its pin 16, Fig. S,'and carries two

pins

19 and 20. The. pins 20 enter. apertures 21 in the movable tooth 22 Fig. 9, to operate said tooth, and the pins 19 enter apertures 23 inthe slide 24-1 Fig. 11. The slide has stops 25 which enter into and cooperate with thecut out portions 26 in the tooth. The slide carries. a pin 27. 28 is a cover plate which is fastened to the. counting drum by a screw 29, F ig. 4.

and which also has an opening 30, Fig. 10.

31 is a lever with a notched end 32-, Fig. 12, adapted to enter through the opening 30 in the cover plate and receive the pin 27 of the slide as shown in Fig. 7.

Figs. 5 and 6 show clearly the operation of the movable or tens transferring tooth. It will be seen that in Fig. 5 the tooth is in inactive'position below the periphery of the counting drum. In Fig. 6 the slide 24 is at the extreme right, having been brou ht into this position by the lever 31 engaging toothless drums 34 and a correspondingly tooth to the right and radially outwardflto project the, tooth beyond the periphery. of

the countingdrum and into active position. The tooth is provided with a slot 33 which fits over the screw 29 aforesaid. The lever 31 is guided on the drum-in a cut out portion as-at 60 in the locking cam 6.

The stops 25 and cut out portions 26 co operate to guide the movement of the tooth. Each counting drum except the first onethe .one to the right in Fig. 1-is provided with a tens transferring tooth. The shafts 11 to the left are provided with very short short tooth 35 operated by means of a single swinging lever 67 pivoted on the drum 34 in a socket 65 in the same manner in which the levers 17 are pivoted on the drums 2. The lever 61 extending from the collars 68 actuates the lever 65 which, by being oscillated, projects the tooth 35 radially outward fromthe drum. The tooth s carried in a socket in the drum and it and the lever 67 are prevented from displacement by a cover plate 7 8 similar to cover plates 28 aforesaid. '79 is an abutment on drum 34 against which the tooth 35 slides. When the short tooth 35 is moved into active position it engages at the proper time the gear 36 to operate the last number wheel in a known manner. 1 a

The lever 31 is provided with a hub 37 and a collar 38 having a cam39. The lever 31 is reciprocated on the counting drum by the following means.

On the frame is suitably pivoted at 40 a carrying lever 41 which has a lug 42 which engages the collar 38 and which also carries a roller 43 adapted to cooperate with an oscillating arm 44, pivoted at 45. When, during the operation of the machine, the

' tens wheel has been engaged by the counting drum and the corresponding number wheel registers'naught, the carrying arm 8 strikes the arm 44 which throws the roller 43 inward and oscillates the carrying lever 41. Consequently the

collar

38 or 68 in Fig. 16 is moved to the right in Fig. 7 and the tens transferring tooth is projected into active position to engage the next or adjacent tens wheel which in turn operates the next number wheel and so on as is known.

In order to prevent an incomplete operation I provide means for positively 'holding the lever 31 in its retracted position when the same has been operated by the carrying lever 41.

Referring to Figs. 3, 13' and 14 the numeral 47 represents a locking hook pivoted at and suitably secured to the frame. A spring 49, only shown in Fig. 14,tends to keep the hook horizontally. The collar 38 is cut out as at 50. Normally the hook and collar are in the position shown at the top in Fig-13, that is, the hook is in engagement with the collar but the cut out portion 50 is opposite the hook. Consequently,

the collar is free to move axially on the counting drum shaft 11 when actuated by the carrying lever 41. The axial and at the same time rotary movement of the collar 38 forces the hook aside as shown in the second position in Fig. 13 and immediately thereafter the collar completes its axial movement and the hook snaps over said collar and locks it as shown at the bottom of Fig. 3, that is during the tens transfera ring movement, thus absolutelylocking the collar against accidental return movement, an occurrence which is apt to happen with a less positive locking device. When, however, the arm 44 moves back into normal position,-the cam 39 again moves the collar 38 to the left in Fig. 3, which it can do by that time the cut out portion 50 is again opposite the hook and the collar'can pass the latter. .The hook new again engages the collar to lock the same. I Y

It will be seen that first, I have provided a positive drive for the counting drums. Second, the tens transferring tooth is placed directly on said drum, a feature which I believe. to be broadly new, and a very simple carrying nlechanism is provided in the space between two counting drums. Finally a positive locking device is provided to insure the active position of the tens transferring tooth.

I do not wish to be restricted to the exact details shown or described except as. the appended claims demand.
