Mounted transversely of and in the rear end portion of the bottom of the case and forwardly of the shaft k is a shaft 0 with which is connected a pair of arms 0 similar to the arms k and which range downwardly and forwardly and the front ends of which are curved upwardly and carry an. impression hammer 0 which ranges transversely of the machine and which is adapted to be thrown into contact with the bottom of the sheet or strip h of paper directly beneath the point where the front carbon ribbon 16 passes thereover, and directly beneath the total adder shaft d, and the wheels g and y mounted thereon as clearly shown in Fig. 2. Rearwardly of the rotary stub shaft is and secured in the same side of the bottom portion of the case is an other rotary stub shaft of with which is connected an armo similar to the arm k and which ranges downwardly and backwardly and is connected at 0 with a yoke-shaped link device 0 the sides of-which are connected with the arms 0 and connected with the outer end of the rotary stub shaft 0 is a key arm 0 with which is connected a total key 0".

Connected with the bottom of the case, and in the left hand side portion thereof as shown in Figs. 2, 3 and 5 are u rights pend 10 the upright 19 being arrange forwardly of the upright p and said uprights are provided at their upper ends; with backwardly directed stopsp ada ted to enga e the corresponding ends of t e transverse y ranging sup orts p of the impression hammers 7: "an 0 and the object of this construction is to prevent the twisting or wrenching of said.

shaft of said roller at said end is an arm 1) with which is connected a link with which ispivotally connected a awl p which operates in connection with t e ratchet and a spring 10 is secured to said link and ears on said pawl.

, The shaft 7: is provided with a rigid arm 1 with which the link 12 is ivotally connected, and in the operation of t e machine as hereinafter described the movement of the shaft k operates the roller i and feeds the sheet or strip k of paper backwardly through the machine.

The total adder shaft cl asses through the bearing d as hereinbefore described, and into the knob or handle a as shown in Fig. 8, and said knob or handle is provided with a charm her 1' through which is passed a screw 1' which is screwed into the shaft d, and placed in the chamber or recess 7' is a spring 1' which bears on the head of the screw 1" and against the inner end wall of the chamber 1.

The end of the shaft d which passe through the bearing (1 and into the knob or handle 0 is also provided in its opposite sides with longitudinal grooves 1" which receive corresponding ribs or feathers r on the knob or handle e. The outer face or head of the bearing d is provided, as shown in Fig. 12, with a segmental cam lug 1 adjacent to which and spaced therefrom is a lug or projection r and the knob or handle 6 is provided with a circular head 8, as clearly shown in Figs. 4-and 11, on the face of which is a pin s which operates on the cam lug r and between said cam lug and the lug or projection T in the operation of the machine as hereinafter described.

The plates 1 which carry'the rlbbon s ools j are provided at their upper edges wit inwardly directed .fianges s in which are formed slits .s through which the ribbons k are passed, in which operation said ribbons are given a quarter turn and a-right an le bend, so that they may be carried paral el with and beneath the shafts c and d.

The top a of the case, and the bottom part thereof are provided at their rear ends with sprin catch devices t by which the top may be he din a closed position, and these catch devices consist, in the." form of construction shown, of. triangular lugs 25 secured to the inner side walls of the top a of the case and spring arms i secured to the bottom of the case at t, and the free ends of which range upwardly and are adapted to engage the triangular lugs 25 as shown at P, and said springs are ,which pass t rough the side walls of the bottom of the case, and by means of which the spring arms i may be forced inwardly so as to disengage the same from the triangular lugs 3 and permit the top of the case to be ear e 1 Mounted on the pivotal supports m of the 1provided with press buttons 15- rock arms m is a yoke-shaped device it whichranges transversely of and above the ratchet bars 6 rearwardly of the yokesha ed device m and the object of which is to orm a sto for a pencil, tool or other instrument use in forcing the rack bars b forwardly in the operation of the machine as hereinafter described.

The item wheels 0 are provided at regular intervals with radial projections 11, on which the numerals are placed, and these radial projections are equally spaced except at one side where there-is a blank s ace u formed by leaving out oneof the ra ial projections 111?, and this blank space a is between the zero and the numeral nine, and in assembling the parts of the machine for use the item wheels 0 are placed on the shaft 0, with the blank spaceyzt down, and in this operation the recording total adderwheels g are placed on the shaft (1 in such manner that the zero marks thereon will be down, while the sight total adder wheels 9 are so laced on said shaft that the Zero marks will up. The operation will be readily understood from the foregoing description, when taken in connection with the accompanying drawings and the following statement thereof.

The operator stands or sits at the front of the machine with the total and item keys at his right. The item recording wheels mounted on the time shaft are placed on said shaft so that the blank spaces a are all down and perfectly alined, and the total adder recording wheels are placed on the total adder shaft so that all of the zeros are down and in perfect alinement, While the sight total adder wheels are placed on said last named shaft so be desired to record that the zeros are all up and perfectly alined.

The operator being careful to place the paper and ribbons properly or as shown in Fig. 2. An ordinary pencil or other instrument may be employed to operate the ratchet bars through the open space I) in the top of the top casing (L2. Now for illustration if it 432.19 the pencil or inplaced behind the shoulder formed by the ratchet tootlnliaving the numeral 8 on its face, of the ratchet bar at the extreme right of the series of ratchet bars eX- posed through the opening I) of the casing. This bar is drawn. forward or toward the operator until the pencil or instrument comes incontact with the transverse stop u, the hook a of the spring tongue at correspond ing. to said bar snaps or rides over the teeth of the bar until-the tooth carrying the numeral 9 reaches the stop it, when the bar will strument is I be locked at this point by the hook a.

' The pencil or instrument is now placed over the 1 in the next bar to the left and is drawn forward until the pencil reaches the stopu; the next ,bar to the left is operatedby placing the pencil or instrument over the 2 and drawingsaid bar forward and the next 'wardly.

bar to the left is operated by placing the P911",

item recorder wheels, the sight total adder.

wheels and the recording total adder wheels so that the numerals, 432.19 appear at the bottom of the time wheels over the ribbon and paper, while the numerals 432.19 appear at the top of the sight total adder wheels and at the bottom of the recording total adder wheels over the ribbon and pa er. 1 The operator now depresses the item ey which operates the impression hammer k to make an impression on the strip of paper kg, and after the impression is made and the time key released the impression hammer is drawn downwardly by the spring m and this downward movement causes the shoulders m on the shaft k to engage the noses n of the trip arms n, drawing said arms downwardly and thus rocking the arm m on its pivot, and the forward end ofsaidarm raises the yoke member m and this operation raises the rear ends of the spring tongues a and disengages the hooks a from the teeth of the ratchet bars b land allows them to be drawn rearwardly by the springs b and the parts are again ready to be operated. I

During the upward'movement of the impression hammer k the arm r carried on the shaftlc operates the feed roller 03 through the link 7) and feeds the strip of paper rear- Thetotal adder wheels remain in the position hereinbefore described, by reason of the dogs h and springs h holding them, and the teeth I) of the ratchet bars I) ride over the teeth of the sight total adder wheels when the bars are drawn rearwardly by the springs b.

When' the yoke member m has been raised sufficiently to release the hooks from the ratchet bars, the trip lugs m operate against the cam faces'n of the trip arms n to throw the shoulders m out of engagement with the noses W and this allows the spring tongues a to force the yoke member at downwardly to return the rock arms m and trip arms n to their normal positions.

It will be understood that at each opera- 4, and draw ment at each rotation of the element or unit ried by the item recording wheels is referably blue, while the ribbon ranging un er the numerals of the total adder recording wheels is preferably red so that a total can easily be distinguished from an item.

In the total adding mechanism the operation, exec t the setting is automatic. The

four mem. ers between each cam disk on the total adder shaft viz :-the sight total adder wheel, the recording total adder wheel,'the ratchet f and the pawl g are so assembled that they form a single element or unit of the total adding mechanism, and the pin h carried by the awl g of one element or unit range to the eft, and rides on the cam diskf and overlies the teeth-of the ratchet f 5 comprising a part of the next element or unit to the left, and by reason of this construction the pin it of the pawl g operates to give the element or unit next to the left a step moveat its right. This is accomplished by the pin 7L when it rides down into the depressionf of the cam disk and engages with a tooth of the ratchet)" of the next element or unit to the left, as clearly shown in Fig. 10. During the operation of the total ad ding mechanism the pin 8 of the knob or handle 6, lies in the recess formed by the cam lug r and lug 1* thus locking the shaft (2 against rotation. When it is desired to reset the total adder mechanism, the knob or handle e is pulled out against the action of the spring 1*, until the pin 8 clears the lugs r and 1- the knob or andle e is then turned to the left until the pin comes in contact with thelug r this operation turns the cams so that the shoulders f 2 contact with the pins h of the pawls g, thus carrying all of the elements or units ack to their normal or starting osition.

When this operation is com leted t e knob or handle is then turned to t e left until the in s rides up on the cam lug r and is pulled into the recess between said cam lug and the lug T when the shaft is locked andthe parts ready for operation.

In Fig. 27 I have shown amodified form of item recording mechanism in which I employ wheels having abbreviations of the names of the months of the year, wheels having 'numerals desi ed to record the days of the months, an. wheels having letters which enable me to record the name of a firm or cor poration in addition to nine wheels having numbers to record the amount of an item or' transaction. This construction will be applicable to adding and recording machines, where more detail is required. I employ in this construction a shaft '0 on which is mounted from left to right a month wheel o day wheels v lettered wheels '0 and numbered wheels 11 all of said wheels carry gear wheels o and are adapted to rotate inde endently on said shaft.
