Specification of Letters Patent. Patented June 6, 1911,

Application filed April 25, 1910. Serial No. 557,362.

To all whom 'it may concern:

Be it known that I, CHARLES A. PLETZ, of

' Chicago, in the county of Cook and State of Illinois, have lnvented certain new and useful Improvements in Registering and Counting Machines; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to themcompanying drawings, which form part of this specification.

. This invention is an improvement in automatic registering or counting devices of illustrate a complete machine 'embo the general type shown in the patent-to Johnson No. 894,506 dated July 28, 1908; and the objects of the present invention are to produce a machine which will be much simpler in construction than the Johnson machine; will be absolutely accurate in operation; will be very durable; will have less p'arts than the Johnson machine, and can be -more economically manufactured, and more quickly assembled; and in which nearly all of the parts can be produced by stamping them from sheet metal by suitable dies, thus enabling the machine to be produced in quantities at little expense and very rapidly; and doing away with nearly all hand labor except that required in assembling the parts. P

I will describe the invention with reference to the accompanying drawi s, which ying the invention, and in the claims followi'ucr the description of-such machine I set forth the parts and combination of parts for which In said drawings ;Figure l is a top plan view of the complete device, with the resetting key applied thereto.

Fig. 15 is a detail View of spring 5 and the adjacent end plate. Fig. 16 is a detail section similar to Fig. 9 but showing the shaft 5 depressed and gear 6 in mesh with pinion 2*. Fig. 17 is a perspective View of the spring finger plate 9, detached. Fig. 18 is a view oft-he escapement lever 4 detached.

The main casing in which the working parts of the machine are housed, comprises a ass-plate 1 from the rear edge of which rises an upstanding flange 1 which is provided with extensions 1 at its ends. The base-plate 1 is provided on its ends with perforated ears 1; and the extensions 1 are provided with perforated cars I on their outer edges. Through the ears 1 or 1 can be passed screws (not shown) by which the conveniently attached to the base-plate 1 and the upstanding projections 1 by means of lugs 1 adapted to engage slots 1 in the base-plate and extensions 1 (Figs. 1 to 7). The end plates 1 can also be stamped out of sheet metal; and when attached to base-plate 1 as sliown in the drawings forms a very strong supporting frame for the working parts. The lugs 1 can be firmly secured in the slots 1 .by riveting the outer end of the lugs, as indicated in the drawings.

The end plates 1 are provided with bearings 1 for a shaft 2, upon which a series of counting or numeral wheels 3 are supported. .Each wheel 3 can be stamped out of sheet metal, in the for-m of a disk having a wide peripheral circumferential flange 3' in which the numerals, OFto 9 inclusive, are

preferably impressed successively, and at equal distances apart as shown in the drawings. Each wheel preferably has a pressed CHICAGO, ILLINOIS, .A CORPORATION hub or sleeve 3 (Figs. 5 and 12) which is slightly longer than the width of the flange,and attached to one end of this hub 3 is a ten-toothed pinion?) (Figs. 6, 7 and 12) which. lies just outside the plane of the flange 3. Pinion 8 may be securely spaced apart from the disk 3 by means of washers 3 strung on the sleeve, see Fig. 12. The other end of the sleeve 3 projects through the disk of the wheel and on it is fixedly secured a disk 3 which has a single notch 3 in its periphery and outside of this disk 3 is another disk or arm 3' which has a tooth 3 registeringwith but outside of the notch 3 (.see Fig. 11) the parts 3, 3 3 form part of the carry-over mechanism as hereinafter described. In the example shown there are six of these numeral-wheels strung on shaft 2 intermediate the end plates 1 the sleeves 3 abutting cndwise on said shaft and keeping the numeral-wheels relatively pro erly spaced thereon; and the ,sleeves are tted closely to said shaft so that while they can be rotated thereon they will not be liable to displacement by momentum, and if the shaft is turned as hereinafter described they are adapted to rotate with the shaftto reset the numeral-wheels as hereinafter explained. Any desired number of such wheels may be arranged upon the shaft, the carry-over being effected from a wheel at the right to the next adjacent wheel on the left throughout the series; and the machine can be adapted to count any desired number by providing it with a suitable number of wheels. Motion is imparted to the first wheel 3, step by step, or one notch at a time, by the following means:

The pinion 3 on the units disk (Fig. 5) meshes with a pinion 4 rotatably mounted upon a shaft 5 supported in a movable frame 5 hereinafter referred to. Pinion 4 which is preferably ten-toothed, meshes with a similarly toothed pinion 4 fast on the stubshaft 4 journaled in a bearing 1 in the right hand end plate 1 of the frame. And

on the outer end of this stub-shaft 4 is fixed an escapementwheel 4 the teeth of which are adapted to be engaged by the teeth-or lugs 4*, 4 on an escapement lever 4 which is attached to one end of a rock-shaft 4 suitably journaled in. the end-plateslfl-the escapement lever 4 being so shaped that when the shaft 4 is rocked to properly oscillate the escapement lever 4 the wheel 4 will be moved one-tenth of a revolution and will in part through the pinions 4 and 4 a onetenth rotation to the units wheel 3 (Figs. 4, 5, 8) the lever 4 is adapted as usual to turn the escapementwheel 4 one notch on one stroke of the escapement lever and to lock the escapement wheel against further rotative movement on the return stroke-of the lever.

The shaft 4 may be rocked by means of a lever 4 connected to the end thereof and provided with a series of apertures in its outer end (see Fig. 4) by which it can be connected to a pulley or push-rod operated from a suitable part of the machine to which the register is applied and which is adapted to oscillate the rock-shaft once for each operation of the machine which it is desired to register in a well known manner.

The escapement lever 4 andshaft 4 may be returned to normal position (with the tooth 4 locking the escapement wheel 4 see Fig. 4) by means of a bent leaf spring 4 attached to the base-plate 1 and engaging the heel of the lever- 4 below the tooth 4*. It will be observed that the escapement lever can be easily stamped from sheet metal, and so may the washers, disks, and counting wheels, as well as the frame of the machine. After the units wheel has moved nine steps, upon the next impulse or step of the units wheel the tens-wheel should be moved one step with the units wheel, and such carryover is effected by the following means: I

On the shaft 5, between the units wheel and tens wheel is loosely mounted a tentoothcd Wheel 3 (Figs. 6, 8 and 12) which is in the same plane as the disk 3 of the units wheel, and its teeth are rounded and are adapted to project into the path of the disk 3 (Fig. 14) so that the wheel 3 cannot turn until one of its teeth registers with the notch?) in disk 3. And although the disk 3 may turn, the disk 3 will not register with any of the teeth of the pinion 3 until 4 3 (Figs 6 and 7 and the teeth of pinion 3 are adapted to be engaged at and during the carry-over period by the tooth 3 on the disk 3 attached to the units wheel, so that when. the units wheel 3 is given its tenth step or impulse the tooth 3* will at that time engage pinion 3 and move it one-tenth of a-revolution; and this pinion 3 is wide enough to engage the pinion 3 on the next adjacent or .tens wheel and consequently the tens wheel will be moved one notch or one-tenth of a revolution 'each time the pinion 3 is moved one tooth and the pinion 3 is moved one tooth each time the pinion 3 with which it is connected, is actuated as described. The pinions 3 and 3 may be fastened together by a rivet 3 or other suitable means so as to rotate as one.

The tens wheel (and each of the other higher denominational wheels on the shaft 2, except the last) ,'is provided with carryover disks 3", 3; and a pair of carry-over pinions 3 3* are located upon the shaft5 between each adjacent pair of numeral- Wheels, so that the tens disk will carry 1 and its attached numeral wheel,

' which is preferably composed of a over to the hundreds wheel; the latter to the thousands wheel and so on; the adjacent sets of pinions 8 3 may be easily spaced'apart upon the shaft 5 by the sleeve 5 on which they are mounted.

To prevent improper movements of the numeral-disks by momentum and also to prevent backward movement thereof, I employ a stop lever 8 (Figs. 6and 7) for each of the wheels except the units wheel. These stop levers are preferably pivoted upon a rod 8, supported in the end-plates 1 as shown, and each lever 8 has a lobe 8 on its upper end adapted to engage between the teeth of the related pinion 3 (see Fig. 6), and prevent casual rotation of said pinion but will not prevent the registering and carry over movements of said pinion and wheel. The levels 8 are suitably positioned opposite their respective pinions 3 by means of. a slotted plate 8 attached to and between the end plates 1 as shown in Figs. 2, 6 and 7 so as to guide the upper ends of the levers and prevent lateral displacement thereof; and the lower ends of the levers 8 are kept in position by means of teats 8 on the heels of the levers, below the pivot rod 8, which teats en-' gage slots 9 in a rocking plate 9 which is provided with upturned end portions 9 by which it is hung upon rod 8. Each lever 8 is also provided with a toe portion 8 which rests upon the top of the rocking plate 9 in front of the teat 8 The plate 9 is also provided on its rear end with upturned fingers 9 (Figs. 2-8) which serve as springs and press against the rear edges of the adjacent levers 8, above the pivot rod 8 (Figs. 4-7), and hold the levers 8 yieldingly in contact with the pinions 3 when the parts are in normal position (Figs. 5 and 6). There is a spring-finger 9 for each lever 8 so that each lever may yieldindependently when its related wheel or disk is turned.

It is very desirable in registers of this sort to provide means for quickly and readily returning the numeral-wheels to zero position, and ,in order to accomplish this quickly and readily I preferably mount the shaft 5, which carries the carry-over pinions 3 3 andpinion 4, ma frame 5 (Fig. 8) U-shaped metal bar, the legs of which are pivoted to the side plates 1 in line with the shaft 4; and preferably one leg of the frame 5 is pivoted upon the shaft 4 (Fig. 5) while the other leg is pivoted upon a stud 5 attached to the other end of plate 1 in line with stub shaft 4, (see Fig. 8). This frame 5 is normally held upward in posit-ion to keep the pinions 4 on shaft 5 in engagement with the pinions on the counting wheels as described by means of leaf-springs 5 which may be fastened to the base-plate 1 in any suitable way. In the simple Way shown in the drawings these leaf-springs 5 have lateral projections 5 which engage in notches in the lower edges of the end'plates 1 (see Figs. 4 and 15) and maintain the springs in place. These springs are s'ufliciently powerful to normally hold frame 5 upward in the position shown in Figs. 5 and 6 and insure the normal engagement of the pinions 3 3 and 4 on the shaft 5 with the pinions on shaft 2 as above described. The frame 5 however may be rocked: so as to lower the shaft 5' and pinions thereon, and move the pinions 3 3 and 4 out of engagement with the pinions and parts on shaft 2. This lowering of the frame 5 is'eftected by means shown in Figs. 3, 4, 9, 10 and 16. The ends of the shaft 5 project through slots 1 in the end plates 1 and one end of theshaft 5 (Figs. 9 and 10) is normally pressed against the edge of the cam disk 6 mounted on a sleeve 6" rotatably journaledupon a stud 6 fast to the adjacent end plate 1 And on this sleeve 6 is also fastened a small mutilated gear 6 which has teeth surrounding about three-fourths of its periphery. The toothed portion of the mutilated gear 6 is adapted to engage or mesh with a small pinion 2 on the adjacent end of the shaft 2 which pinion 2 can be most conveniently and cheaply formed by stamping the end of shaft 2, as indicated in the drawings, see

Fig. 10. The disk 6 has a cam notch 6 into which the end of shaft 5 normally projects when theframe 5 is in raisedposition and the parts are in operative reglsteringpositions. But ifthe cam disk 6- be rotated the shaft 5 will be forced out of the notch 6 and down (Fig. 16) until the pinions on, shaft 5 are out of engagement with those on shaft 2, and shaft 5 will be held down (Flg. 7) until the cam 6 has made a complete revolution and the end of shaft 5 can again move into the notch 6. The untoothed portion of the mutilated gear6 is preferably located opposite the notch in the cam disk 6 so that the teeth on gear 6 cannot come into operative engagement with the pinion 2 on the shaft 2 until the frame 5 has been lowered sufliciently to move the pinions thereon out of mesh with those on shaft 2; but when the toothed portion of the mutilated gear 6 meshes with the pinion 2 on shaft 2 upon further rotation of the gear 6 a rapid motion is imparted to the shaft 2 and the now freed numeral-wheels thereon by reason of the frictional fit of the hubs 3 of said wheels on the shaft 2, and said wheels will be turned forward until they are respectively arrested at the zero ping'devic'e (Fig. plained.

The end portions 9* vided with teeth 9 (Figs. 6 and 7) which engage notches 5 in the adjacent ends of the frame 5 so that when the frame 5 is depoint by a suitable stop- 7) as hereinafter exof the plate 9 are progagement with the pinions 3 (see Fig. 7)

thus leaving the numeral-wheels entirely free on shaft 2 and permitting thenr to be readily reset by rotating the shaft 2 inthe manner above described.

As shown in Figs. 6 and 7 each numeralwheel 3 is provided with a peripheral lug 3 which is adapted to arrest the wheel at the zero point, whenthe wheels are being reset, by abutting against a stop plate 7 which plate is provided with perforated ears 7 a at its ends by which it is hinged or pivoted u on the rod 7 which is supported in suita le apertures in the end plates 1 I prefer to use a rod to transfix the end plates and ears 7 as shownon account of simplicity of construction and ease in assembling the parts. The stop, plate 7 has a depending finger 7 whichextends through a loop 5 on the rear bar of the frame 5 (see Figs. 3-6-7) and which can be cheaply struck up out of metal of the said frame, and the lower end of the finger 7 e is curved in such manner that when the frame 5" is lowered to disengage the pinions as indicated in Fig. 7 preparatory to the resetting. operation the lower end of the finger is pushed backward and consequently thestop plate 7 is rocked so that its uppler edge is moved inward toward the per1p cries of the numeral or registering wheels and into the path of the lugs 3 on said wheels, so that when the wheels are turned by rotating the shaft 2 as described, they cannot turn after their lugs 3 are arrested by the plate 7 and in this manner all the wheels can be quickly brought to zero position during one revolution of the mutilated gear 6. When the frame 5 rises so as to return the pinions thereon into mesh with the pinions on the numeral wheels (Fig. 6) the finger 7 is swung inward so as to rock plate 7 out of position to engage the lugs 3 on the wheels and consequently so long as the parts of the machine are in registering condition tlfi stop bar is inactive.

In order to prevent tampering with the register, or unauthorized or undesired resetting of the numeral-wheels to zero, the sleeve 6 is preferabl by means of a specia setting key 6 which is normally detached therefrom. As shown the outer end of sleeve 6 is threaded as at 6" and may be engaged with the internally threaded socket in the tubular stem of the key 6 (Figs. 13, 10) which can be inserted through a suitable opening in the end wall of the outer casing 10 of the machine, and screwed onto the sleeve 6*- and employed to turn the latter. One revolution of the sleeve 6 18 ordinarily sufficient to reset all the numeral wheels to zero, as above demade rotatable only end plateslO have perforated ears 10" on their top and front edges and the cover 10 has lugs 10 on its ends adapted to be inserted through the perforations in ears 10"; then the ears 1O are bent over onto the cover plate, as in Fig. 1, and the lugs 10 are bent down a ainst the end plates, as shown in Fig. 1; ocking the parts together in a simple but effective manner. The end plates 10 also have lateral perforated lugs 10 through which screws 10 may be passed to fasten the casing to the back plate as shown. Cover plate 10 is provided with a series of slots 10 through which the proper numerals on the wheels can be seen, see Fig. 1).
