Application filed 3111 12,

To all whom it may concern:

Be it known that we, TrroMAs K. DIXON, ALEXANDER KLEIN, Jnssn C. Gore, and Gnome R. GHENT, citizens or" the United States, residing at Houston, inthe county of Harris and State of Texas, have invent ed certain new and useful Improvements in a Transfer Adding and Totaling Machine, or which the following is a specification.

This invention relates to new and useful improvements in a transfer adding and totaling machine. v

Une object of the invention is to'provioe a machine of the character described which has been specially designed for the purpose of mechanically transferring the totals registered on adding machines, to the totaling machine whereby a register is made the grand total of the amounts indicated by the different individual addingmachinesv The machine herein described is particularly useful in connection with our mechaniof keeping a cal store described in our application for patent thereon, filed in the United States Patent Office on the 7 day of June, 1921, under Serial No. 475,629, for the purpose total register of the individnal adding keys used in the operation or said store.

Another object of the invention is to pro vide a machine of the character described which in addition to transferrins and c0n1- bining said totals will set back the adding machine, or adding key to zero so that it can be re-used by other customers.

i/Vith the above and other objects view this invention has particular relation to certain novel features of construction opera, tion and arrangement of parts, example of which is given in this specific tion and illustrated in the accompanying drawings, wherein:

Figure 1 shows a side view of the machine with the casing in section Figure 2 shows a plan view thereof pan tially in section.

ence designate similar parts in each or 0 finance the 1 designates the cascam shaft is fastened cam shaft carries a plurality oi spaced cams 7 and it has a central here 8 through which the release rod 9 works. The outer end of this rod is re duced and extended through the knob and is formed with a push button 10 which works in a socket 11 the outer end of said knob. A coil push spring 13 is interposed between the push end or"- the shaft 2 and is confined within the knob The inner end of the release rod 9 is formed into a release keylt. This rod is normally locked against operation by means of the sectional spring! seated plnngers it which are seated in the socket 16 in, the block i and wo through aligned bearings and release rod. The each plunger is equal in nness of the wall a whi works so th t is in alignn will i length to the cam shaft th when said min with said against operatf button and the opposing oration to the plungers 15.

The inner end of the rod 18 carries the pivoted dogs 21 which are actuated by the (ey 14, when in co-acting relation therewith depress the plungers 20 into releasing position and at the same time the plungers 15 are similarly released by the key 19, so that the interlocking shafts 2 and 17 are free to turn. 7

The key is equipped with an adding mechanism which will now be'described:-rotatably mounted on the shaft 22 are a pluralit of rotary units each complete unit consisting of the ratchet wheel 26, the star wheel 23, the counter disc 24, and the stop lug 25, arranged in the order stated, Transfer bars 27 are slidably mounted on the bearing shaft 28 and one end of each bar is formed into a dog, said dogs coacting with the corresponding aligned ratchet wheels 26.

It is contemplated that the counting discs 24 will be rotated by suitable adjustable segments, (not shown) which work through the slots 29 of the casing 1, in mesh with the star wheels 23. Each counting disc has the numerals from 0 to 9 thereon which come successively before the aligned windows 30 of the casing 1, as

the discs are rotated, as shown in Figures 2 and 5. Any number of counting discs may be used, depending upon the required capacity, or range of the adding key. As shown five discs are disclosed. The first registers units or cents, the next registers tens or dimes, and so on, the amount indicated on any disc being ten times the corresponding amount indicated by the next receding disc of a lower denomination. W ile any disc is being rotated the corresponding transfer bar is driven forwardly. carrying its dog out of the range of the aligned ratchet wheel until said disc has performed nine tenths of a complete rotation, that is, has counted tonine, and then said dog will engage with and actuate the ratchet wheel 26 of the next unit. to accomplish apartial (one tenth) rotation of the counting disc of the next higher denomination and transfer the amount indicated by the next partial rotation of the former disc, to the latter.

In order to bring this action about oscillating levers 30' are mounted on the bearing rod 31 and at their free ends-are .pivoted to the respective dogs 27. These levers have the offset lugs 32- and the corresponding cams 7 work against said lugs, and drive the levers and the corresponding transfer bars 27 forwardly, and the levers are returned by the tension of the coil springs 33. \Vhen the transfer bars are driven forwardly the shoulder 34 of each dog rides upon the adjacent end of the pawl 35 to hold the dog of said bar out of engagement with the aligned ratchet 26. The pawls 35 are mounted on the bearing rod 36 and are aligned with the stop lugs 25, and held yielding thereagainst by means of the tension spring 3 When a counting disc has accomplished nine tenths of a revolution the sloping side of the lug 25 pushes back, orret-racts, the corresponding pawl 35 and thereupon the shoulder 34, of the corresponding bar 27, is pulled down into the notch 38 of the pawl 35 and the dog of said bar 27 then engages with the ratchet wheel 26 and upon the next backwardmovement of said bar the ratchet, and the corresponding countin disc is turned one tenth of a rotation tfius in effect transferring the amount counted by the preceding counter to it. A pull spring 39 is attached, at one end, to each bar 27 and .at "its other end to the rod '36 and is ef fective to hold the shoulder 34 against the adjacent end of the corresponding pawl 35, and to cause it to drop into the notch 38 when said pawl is retracted,

As the bar moves backwardly to effect this partial rotation of said ratchet wheel the shoulder 34 rides up out of the notch 38 and thelug 25 havin passed the pawl 35 said pawl drops in behind said lug, acting under the influence of the s ring 37, so that the dog of said bar 27 wil thereafter be held out of engagement with the aligned ratchet until the corresponding pawl 35 is.

again retracted, as hereinbefore explained.

From the foregoing it will appear that each counter disc, in effect, adds one for each partial rotation up to nine, and with the tenth partial rotation the amount added by it is transferred to the next succeeding counter disc of a higher denomination.

\Vhen the adding key is not in operation the slots 29 are closed by a sliding shutter 40 which works within the casing 1 and partially surrounds the counting units forming the adding mechanism. This shutter has the transverse slots 41 out therethrough and it is actuated by the lever 42. This lever is pivoted to the bearing block 43, confined within the casing 1. One end of the lever is pivoted to the shutter and its other end rides on the cam 44 which is fastened on the shaft 2.

\Vhcn the adding key is inserted into the mechanism with whic it works and the neatoe and operate the corresponding star wheels 23, and then said cam 44 again actuates said lever to again shift the shutter to close said slots 29 and thus protect the counting mech anism against interference.

his to be understood that the mechanical adding key hereinbefore described is priinarily designed to be used in connection with our mechanical-store described in the application for United States Letters Patent hereinbefore referred to. 8

When a customer enters. the store he procures said key and by its use gains access to the goods and as the purchases are made the total cost of the articles purchased is registered by said key. The key is then returned to the cashierand the price, registered by the key, is paid to the cashier. A register of said price must be made and the key must be set back to zero so that it can be delivered toanother customer for use. It

' is obvious that a number of these keys -Will be necessary to accommodate all customers.

A machine for totaling the registers of the keys used and for setting said keys back to zero will be necessary for conducting the business with dispatch. Such a machine will now be described The numeral refers to the casing which is formed with a pocket, or keyway 4-6 therein to receive the mechanical adding key, heneinbefore described. When this key is inserted its shaft 2 will align with the crank shaft d7, which is rotatablein suitable bean ings in the casing 45 and whose outer end has the crank 48 by means of which it may be turned. When in operative position the shafts 2 and 47 are released for rotation and clutched together by means of a mechanism disclosed in Figure 8 and hereinbefore described. The crank shaft 47 has a spur gear 49 fixed thereon which drives a train of spur gears 50, 51 and 52, the latter of which is fixed on the counter shaft 53. The gears 50 and 51 rotate on suitable spindles 54- and 55 carried by the web 56, and this web is formed with bearings in which the respective shafts 47 and 53 rotate. The shaft 47, as it is turned will rotate the shaft 2 and will also rotate the shaft 53 in the opposite direction.

The inner end of the shaft 4:? has a disc 57 fixed thereon, whose inner face is formed with a cam-shaped groove 58 in which the roller 59 runs. This rolleris carried by the link 60 one end of which has a long bearing 61 to receive the hub of the disc 57 and the other end of which is pivoted to the upper end of the arm 62. The lower end of this arm is fixed to the frame of an adding mechanism 63 which totals the sums indicated by the mechanical adding keys. In other words the amounts carried by said adding keys are transferred to the adding mechanism 63 and the totals thereby registered.

The mechanical construction and operation of this totaling machine 63 are similar to the mechanism of the key shown in Figures 5 to 8, inclusive, and will not be further described in detail.

End brackets ea, b4: have their lower ends formed into bearings 65, 65 in which the I shaft 53 works, and one of these brackets is extended forming the arm 66 whose free end has the spur gear wheel 67 rotatably m0unted thereon.

The upper ends of these brackets 64 are formed with aligned bearings 68, 68 in which the shaft 69 rotates. Keyed on one end of the shaft 69 there is a segmental rack member 70, and fixed thereon, between the bear-. ings 68 there is slotted cage 71f Loosely mounted on the shaft 69 there are the segmental rack members 72, each composed of wings 73 and 74 having gear toothed margins. These rack members 72 work through the slots 75 of said cage. A pair of pull springs 76 are attached to each wing 7d, at one end, and at their other ends these springs are attached to said cage. Each wing 73 has an arcuate slot 77 therethrough, forming bearings, which move on the bearing rod 7 8 which is anchored in, and extends transversely through, the cage.

@ne of the bearings 65 is formed with a projection 79, forming integrally therewith, and a screw 80 is threaded therethrough, forming an adjustable stop, which is arranged opposite the abutment 81 which stands up from the bottom of the casin 45. A pull spring 82 is attached at one end or the projection 79, and at its other end it is fastened to the casing 45.

An arm 83 is formed with a bearing 84 at one end, which works on the shaft 69, and its other end has a bearing pin 85 which projects laterally through an oblong bearing slot 86 in the link 60.

Vlhen the crank -8 is turned the shaft 4:7 rotates the shaft 2 and the cam 44 rides out from under the end of the lever 42. Thereupon the pressure of the push spring 87 actuates the shutter 40 to align the slots 41 thereof with the slots 29 of the casing 1, so that the segmental wings 73 may work through said slots into mesh with the star wheels 23 of the adding key. At the same time the cams 7 operate, through the add-- ing key mechanism described, to carry the bars 27 out of engagement with the ratchet wheels 26 to permit their reverse rotation until they are stopped by the contact of the lugs 25 against the corresponding opposing dogs 35, in which position the zeros of the, counting discs 24 will align behind the 'the star wheels 23 with the corresponding star wheels 23.

windows 30 and the adding key will then be set back for use by another customer. As the link 60 moves under the influence of the cam groove 58 the frame 63 is partially elevated causing the star wheels 23 to approach the opposing segmental wings 74 with which they are designed to mesh, and the brackets 64 move with said link being swung around on their shaft 69 under the influence'of the pull spring 82, until the wings 7 3 are in position to mesh with the star wheels 23, at which point the stop 80.

contacts against the abutment 81, as shown in Figure 3. The segmental rack 88 has in the meantime moved into position to mesh with the rack member 7 O and the further movement of the link 60 will further elevate the frame 63 and bring the star wheels 23' into position to mesh with the rack teeth of the wings 74. The further rotation of the shaft 47 will now operate, through the rack 88, to rotate the member and the shaft 69 to which it is fixed, and the rack teeth of the wings 73 will mesh with and rotate the star wheels 23, of the addin key, reversely, until they are carried back to Zero and stopped, as above explained. Some ofi these star wheels will be stopped before the others, this depending on their respective positions when the adding key is inserted in the socket 46, and the springs 76 of the corresponding segments, also stopped, will yield to permitthe others to move on until all of said star wheels 23, and the counter discs 2a are returned to zero position.

The wings 73 and 74 have a corresponding number of teeth. The. latter mesh with when the former mesh The numerals carried by the counter wheels 24 are arranged reversely with respect to the arrangement of the numerals of the counter wheels 24 so that as the latter are turned backwardly the former will be turned forwardly with the result that the numbers taken off of the adding key will be totaled onto the adding mechanism 63.

The continued rotation of the shaft 4:7 will operate through the cam groove 58 to move the link 60 backwardl which in turn will operate through the arm 62 to lower the adding mechanism 63 out of operative connection with the wings 7 4, and as said link 60 moves on backWa-rdly it will operate through the link 83 to swing the brackets 64, 64 backwardly and release the wings 73 from the star wheels of the adding key. The pull of the springs 7 6 will then bring the segments '72 back in alignment in their original positions, relative to the cage 71.

The rack segment 89, fixed on the shaft 47 is now in position to intermesh with the near 67 and as the shaft 47 continues to rotate the rotation of said gear is reversed, thus reversing the movement of the rack member 70 and restoring the cage 71, and the segments carried therein, to original, or startmg position.

The adding key may then be removed, and another inserted and the operation repeated. The sums indicated by the adding keys will thus be transferred to and totaled on the adder 63.
