DAYTON, OHIO, A CORPORATION OF CASH REGISTER.

Application filed April 23, 1920. Serial No. 376,066.

This invention relates to improvements in accounting machines and has more particular relation to those machines which, in addition to making a record of transactions upon totalizers, make an additional printed record of all transactions and in particular accumulate and print totals.

The object of this invention is to provide improvements in the drawer releasing device, whereby the drawer is released by the totalizer resetting mechanism.

With these and incidental objects in view, the invention consists in certain novel features of construction and combinations of parts, the essential elements of which are set forth in the appended claims, and a preferred form of embodiment of which is hereinafter described with reference to the drawings which accompany and form part of this specification.

(lf said drawings:

Fig. 3 is a transverse section through the printer showing the printing wheel actuating mechanism and the counter turn-to-zero mechanism.

Fig. l is a detail view of part of the totalizer turn to zero mechanism.

Fig. 5 is a detail view showing the drawer release mechanism.

The above mentioned improvements have been shown applied to a machine of the type disclosed in the Letters Patent to J. P. Cleal, No. 718,565 and 773,060, granted January 13. 1903, and October 25, 1904, respectively, and in the application of E. J. Von Pein, Serial No. 293,14il, filed April 28, 1919. 'The invention relates specifically tothe drawer release, and is applied. to a machine of the specific form shown in said application of Tea Pein. This machine will, therefore. be described only briefly, reference being had to the Von Pein application for a full understanding thereof.

The machine disclosed is, in general, the same as that shown in the Von Pein application referred to. In another application 24 is rocked.

of Von Pein, No. 376,088, filed April 23, 1920, a construction is disclosed in which the cash drawer is automatically released whenever a total is recorded. The mechanism here illustrated is a specific improvement over that of the Von Pein application No. 376,088. Only so much of the general mechanism is disclosed as is necessary to give an understanding of this improvement; and the same will be described only so far as is necessary to understand the specific invention here involved.

Referring specifically to the machine embodying the invention, and at this time hearing in mind that all the action thereof is started by the keys at the front of the machine, the mechanism for transmitting motion from the keys to the other parts will now be set forth. The keys 20 (Fig. 1) are pivoted upon a transverse shaft 21. When the forward end of one or more of the keys 20 is depressed a key coupler 22 pivoted on studs 23 having hearings in the side frames Attached to the rear end of each key 20 is an upright member 25, formed with a slot 26, adapted, when the key 20 is operated, to engage a transverse rod 27 carried by a rocking frame 28 pivoted on a transverse rod 29 to rock said frame a distance, corresponding to the'value represented by the key. There is a frame 28 for each denominational group of keys 20, and each of the frames 28 has attached to it a registering segment 30. All of this is well understood in the art and forms no part of this invention.

A plurality of totalizers may be used as in the aforesaid patents to Cleal, and the application of Von Pein No. 293,141, each com' prising a plurality of rotatable elements. each appropriate to a numerical order; but neither the number of totalizers nor the form thereof is important to an understanding of this invention. In Fig. 1 a single totalizer or totalizer frame 31 is illustrated. This totalizer is known as a recording totalizer and when an additional totalizer is employed it is referably of the reading type shownin t e Cleal patent though it is obvious that a recording totalizer as shown in the Von P'ein application could be used. When this frame is rocked to engage the totalizer with the registering segments 30, the rotatable elements thereof which carry the gears 32 will be caused to rotate as the registering segments 30 are rocked. The gear 32 meshes with a gear 33 rotatable on a shaft 34 mounted in brackets carried by the rock ing totalizer frame 81. Eacli gear 33 carries with it a stepped scroll plate 35. By this means any movement of the totalizer elements will be transmitted directly to the stepped scroll plates so that said plates are caused to rotate to positions dependent on the amounts entered on the elements of the totalizer. This is fully set forth in the application of Von Pein, No. 293,141, referred to.

The segments 30 (Fig. 1) also mesh with pinions 89. One of these pinions 89 is fast to the left hand end-of a shaft 40 while the others are mounted upon the left hand ends of telescopic sleeves 400 (Fig. 3) and thus communicate motion to printing wheels 41 (Fig. 2) for printing thedetailed transactions on the issuing strip in a manner fully set forth in the Von Pein application No. 293,141, referred to.

The printing from the type mechanism is performed upon an issuing strip 46 (Fig. 2) which is run from a supply roll 47 around a guide roll 48 to a severing plate 49, mounted on the printer hood of the cabinet. This strip passes between the type wheels 41and the platen 50, so that when the platen is operated, an impression will be made on said strip. To secure a visible impression a suitable continuous inking ribbon is wound around guide rolls 52 mounted in the printer frame and over an inking roller 58 mounted upon a stud 54 projecting from the printer plate. This ribbon is held taut by a tension roll 55 supported in a frame mounted upon a rod 56 pivoted in the printer frame. The ribbon is fed at each operation of the keys For the purpose of feeding the issuing strip 46 there is provided a feed roller 57 (Fig. 2) mounted on a shaft 58, journalled in the printer plate 59 and having fast thereto a ratchet wheel (not shown) which is' en'- gaged by a spring controlled pawl 60 pivoted on an arm 61, said arm being fast to the stud 23 upon which the key coupleroscillates. At each operation of a key 20, which imparts an oscillatory motion to the key coupler 22, the pawl 60 will cause the feed roller 57 to rotate in a counter-clockwise direction. A spring controlled retaining pawl 62 prevents retrograde motion of the roller 57.

Directly above the feed roller 57 and in contact with the same is a tension" roller 63 freely mounted on a stud 64 carried by a spring controlled lever 65 pivoted 011 a stud 66 mounted in the printer plate 59. The issuing strip 46 passing between the feed roller and the tension roller 63 will feed toward the front of the machine a distance equal to the line spacing of the printing at each operation of a key 20.

The arm 61 which oscillates with the key coupler is connected by a link 67 to the ribbon feeding lever 68, for conveying motion to the ink roller 53 previously described. This mechanism is all substantially the same as that shown in Von Peins application N 0. 293,141 referred to. The total printing crank (Fig. 2) which primarily serves as an actuator in connection with the printing 4 of the total, is freely mounted upon a stud 76 supported in the plate 59 and is adapted to be given two revolutions in a clockwise direction at each operation. The crank is connected with a gear 77 which meshes with a gear 78 fastened on a driving shaft 79.

Securely fastened to the gear 78 is a plate 80 carrying a projecting pin 81 which engages a branch 82 of an arm 83 pivoted at 87 to the plate 59. gear 78 is a plate 84 having a notch 85 which engages the end 86 of the arm 83. Attached to the arm83 is a spring 88 which, when the end 86 of the arm 83 is released from the shoulder 85 of the plate 84 by a slight clock- Wise rotation of shaft 79, will swing the arm 83 downward until it contacts a pin 89. The end 86 of the arm 83 being disengaged from the plate 84 the crank 75 can now be rotated to perform its previously described functions, toward the end of which the pin 81 mounted in the plate 86 comes into contact with the branch 82 of the arm and raises the arm into the path of the shoulder 85 of the plate 84, and thus the shaft 79 is stopped at the completion of its cycle.

Fast upon shaft 79 are two open cams 90 and 91 (Fig. 3) which impart an oscillatory motion to a member 92 by being in contact with anti-frictionrollers 93 and 94 respectively. Said rollers are carried on studs mounted in the member 92 which is pivoted upon a shaft 95. Carried in the lower end of oscillatory member 92 is an antifriction roller 96 which engages with a feeding device (not shown) for the issuing strip feed roller 57.

A plate 97 (Fig; 2) pivoted upon a stud 98 mounted in the arm 61, is used to lock out the totalizing mechanism when the keys are being operated. The plate 97 is slotted to slide on a guide stud 99 mounted in the printer plate 59. The end of the plate 97 is so shaped as to enter a slot 100 in the plate 80 fastened to the gear 78. .From the foregoing description and the drawing it can be seen that during the operation of the keys 20-the totalizing crank 75 cannot be operatedand" if the'eranki's beingrotated the keys- 20 will be locked against operation Also fastened to the because the plate 97 cannot enter slot 100. These matters form no part of the present invention and are fully shown and described in the application of Von Pein No. 293,141, referred to.

As the printing mechanism shown is likewise described in detail in the application of Von Pein No. 293,141. and forms no part of this invention, it will be but briefly described here. At their left hand ends, sleeves 37 1) have each secured thereto a yoked member 105. Each of these menr hers has an arm 36 located adjacent one of the stepped scroll plates 35 and is adapted to be brought into contact with the steps of the plates At their right hand ends the sleeves 3T carry gear segments 106 (Fig. 8) which mesh with mutilated gears 10'? mounted to turn on a shaft 108. At the rear the mutilated gears 10? engage with th gear segments 109 mounted to turn on a shaft 110. Extensions upon said gear segments 109 are disposed to the rear where connections are made with springs 111. lhese springs at their lower ends are connected with rods 112 carried by the oscillating member 92, previously described.

As the frame is rocked in a clockwise direction (Fig. 3) this movement will be transmitted to a yoked member 113, pivoted on the shaft 110, through the medium a link 114. As the yoked member 113 is moved in a clockwis direction a plate 115 fastener thereon will tend to be withdrawn from contact with the segments 109. The segments 109 are however held in contact with the plate 115 by the springs 111, which are further tensioned by the clockwise movement of the frame 92, and the segments 109 will travel after the plate 115. Through the gear connections 10? the sleeves 37 (Fig. 1) will be rocked in a clockwise direction (Fig. 3) when the segments 109 are rocked as just above described. This rocking of the sleeves 2-37 in a clockwise direction will carry the yoked members in a similar direction until each of the arms 36 is brought into contact with the positioned step of its appropriate stepped scroll plate 35, thus arresting further movement of the mechanism just above described. This will stop the gear segments 109 in positions varying with the positions of the scroll plates 35, but the yoke 113 and the plate 115 will continue the full extent of movement as determined by the movement of the member 92.

The mutilated nears 107 (Fig. 3) are provided w'th downwardly extending arms oarrying a gear segment 116 which meshes with pinions 11? carried by the left hand ends of nested sleeves 118. These sleeves 118 carry on their right hand ends type wheels 38 (Fig. 2) for printing a total. It. will thus be seen that as the gears 101 are moved by the action of the segments 109,

which movements are arrested by contact of the arms 36 (Fig. 1) with stepped scroll plates 35, the type wheels 38 (ll-lg. 2) will be moved to positions representing the ad justment of the stepped scroll plates 35, which adjustment is appropriate to the total of the items which have been entered on the totalizer.

After an impression is taken from the type wheels 38, the frame 92' (Fig. 3) rocked in a counterclockwise direction, which movementwill be transmitted to tho yoked member 113 through the medium of the link 114 which thus restores all. of the segments 109 to normal position as shown in Fig. 3. This restoration of will likewise effect the restoration of the gears and segments 10? and 106 and sleeves 3?, thus rocking the arms out of contact with the stepped scroll plates 35. movement at the same time is transmitted through the segments 116 to the total printing wheels 38, thereby restoring said total printing wheels to normal zero position. The total printing wheels 38 twice the diameter of the item printing wheels 41 and contain two sets oftype characters, one setfor printing upon the issuing strip and the other for printing upon a total record strip 119. The total record strip 1' 9 is fed from a supply roll 120 which is freely mounted upon a stud 121 proj cting from the printer plate 59, around guide rollers 122 and onto a receiving roll At an appropriate time, and by the open ation of the totalizing crank, a platen hearing member 124 will be raised bring ing a laten 12.) into contact with the type wheels 38. Platen bearing member 124 is pivotally mounted upon an arm 12o, pivoted on a stud 12? which projects from the printer plate 59.

Simultaneously with the making of an impression upon the issuing strip a platen 128 will come into contact with the type on the top of the total printing .vheels 38 to cause an impr ion to be made of the upon the total strip 119. Saidplaten is ried in an arm 129 pivoted on astud 130, and connected by a link 1531 to the lever which is fast to the aim 126.

When printing a total it is essential to return to Zero position the totali? r eleirr s as well as the stepped scroll plat 35 of t e totalizer leaving it at the end of t to ing operation clear of all items, for the accumulatioi'i of another group items of another period.

Pivoted upon the shaft 110, (Fig. 2) is a segment lever 134 connected at the rear end by a stud 135 and a link 136 to an adjustable eccentric stud 137 mounted in the This (Fig. are

link 114 connected to the oscillating frame 1 92 rocked each time the totalizing crank is operated.

Fig. 2) by mechanism previously described.

Said segment lever 134 being connected to the oscillating frame 92 will rock first in a clockwise direction and then in a coun' ter-clockwise direction at each totalizing op eration, and being in mesh with a partial gear 148 fast on the shaft 108 will impart a rocking motion to said shaft.

Fast on the shaft 108 and inside the printer plate (Figs. 3 and 4) is a segment gear 138 which meshes with a gear 139. Secured to the gear 139 is a disk 140 carrying a spring controlled pawl 141 engaging a ratchet 142 fastened to a gear 143. Said gear is in mesh with a pinion 144 fast on a shaft 145 which rotates in a clockwise direction.

Coupling the shaft 145 (Fig. 5) with the totalizer shaft 146 (Figs. 1 and is a shaft 147 which is connected by universal joints at its ends to the shafts 145 and 146 to permit of a rocking motion to the totalizer frame or frames. A more detailed description of the above mechanism is given in the Letters Patent of the United States No. 1,555,534, issued to E. J. Von Pein, September 29, 1925.

The rotation of the shaft 146 (Fig. 5), for the purpose of returning to normal zero position the accumulator members of a totalizer, and the opening of the cash drawer, 1S timed to occur after the printing of the issuing strip and the record strip during the operation of the crank 75. The crank 75 will impart a rocking motion to the gear train actuating the pawl 141 (Fig. 3) and cause said pawl to back up a distance of two notches in the member 142 and then on its movement forward to rotate the gear 143 two-thirds of a revolution and the gear 144 one complete revolution.

Fast on the left hand end of shaft 146 (Figs. 1 and 5) is a cam 150, which at the rotation of the shaft 146 will actuate the mechanism for releasing the cash drawer which is normally held in closed or locked position. Engaging the cam 150 is a pin 151 projecting laterally from a lever 152 pivoted upon a stud 153 carried in the totalizer frame 31. The forwardend 154 of the lever 152 carries a pin 155 which engages in a slot 156 formed in a plate 157. This plate 157 (Figs. 1 and 5) has two elongated slots 158 and 159 engaging respectively studs 160 and 161. These studs 160 and 161 are mounted in a bracket 162 which is fast on a frame member 163.

A spring 164 will normally hold the plate" 157 in its upward position, and the'pin 151 in the lever 152 in contact was the cani- 150. Projecting laterally from the lower end of the plate 157 is a pin 167 which has on its end a tenon 168 engaging a hole in an arm 169. The end 170 of device. the arm 169 is bifun cated to engage a stud 171 mountedin-a 1 frame member 173. A lever 174 is-pivoted on the stud 171, and carries a stud 175 engaging an elongated opening 185 formed in the arm 169, to form a connection between the arm 169 and the lever 174, so that the rocking of the arm 169, in a clockwise di rection by the cam 150, will cause'the level- 174 to swing on the pivot 171 and release the cash drawer 17 6.

The rear end 177 of the lever 174 forms a latch and engages with notches 178 formed in a wheel 17 9, loosely mounted on a stud 180 carried in the frame member 173. lever 174 is held in engagement with the notched wheel 179, with the stud 175 engaging the upperpart of the elongated opening 185, by a spring 181. The arm 184 e011- nected to the lever 174 and to which the spring is attached has no other function than that of a connection in this invention.

The cash drawer 176 has fastened on the rear end a formed plate 190, having a projection 191 engaging with the notches 178 in the wheel 179. This plate 190 holds the cash drawer 17 6 in closed or normal position until the latch 177 is disengaged from the notched wheel 179, at which time a spring 192 being under compression, will cause the cash drawer 176 to move forward. As the cash drawer moves forward, the projection 191. will cause the notched wheel 17 9 to rotate in a counter-clockwise direction until the projection has moved out of engagement with said wheel.

In closing the cash drawer 17 6 ready for of the notches 178 of the wheel 179, rotating said wheel in a clockwise direction. The rotation of the wheel 179 in a clockwise direction will raise the latch 177 out of engagement with the notch 17 8 and into engagement with the next notch by the action of the spring 181.

As the notched wheel 179 rotates in a clockwise direction at the closing of the cash drawer 17 6, the lever 174 will swing on its pivot 171 without conveying motion to the arm 169, the stud 175 moving in the elongated opening provided for this purpose.

It will be seen that when the shaft 146 is rotated upon an operation of the crank 75, the cam 150 will rock the lever 154 and through the medium of plate 157 will rock lever 169. The latter lever 169 will then through the medium of slot 185 and stud 175 rock lever 174 to release the notched wheel 17 9 thereby releasing the cash drawer.

It is necessary at times to open the cash drawer 176 without operating the totalizing For this reason the plate 157 is provided with an upwardly extending portion 93 constituting-a means by which the-plate This may be moved and consequently the drawer latch swung to unlatching position. This portion is normally under lock within the cabinet and is accessible only to the proprietor.
