NICHOLAS MILLER, OF GRAND RAPIDS, MICHIGAN, ASSIGNOR, BY MESNE ASSIGN- MENTS, TO ADDJNDEX CORPORATION, A CORPORATION OF DELAWARE.

ADDING AND RECORDING MACHINE.

Application filed February 12, 1921.

To all whom it may concern:

Be it known that I, NICHOLAS MILLER, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Adding and Recording Machines, of which the following is a specification.

Paper feed mechanism for adding machines-T he invention relates to the mechanism for feeding the paper to be printed or tabulated on, in the class of machines in which a wide carriage and paper are employed, for the purpose of printing two or more columns of numbers, or several items in a single line.

In such machines the sheet orstrip of paper is ordinarily fed between a platen roll having a step by step rotation and one or more pressure rolls, the platen roll being turned one step by the adding mechanism after theprinting of each number to bring a new (blank) line into position opposite to the type to receive the impression of the next number.

My improvements supply adjusting means for the platen roll turning mechanism of such machines, by which the automatic operation of such mechanism is suspended at will, for instance during the printing of several numbers or items in a single line. and

the roll will not be turned at the end of each printing operation. A reverse operation of said adjusting means will cause the roll to be automatically turned in the usual manner at the end of a printing operation. I further combine in my ad'usting means devices whereby the roll wilf be automatically turned a short distance, or a greater distance, for the purpose of correspondingly spacing the lines of printing, as may be desired.

With such ob ieets in view, as well as other advantages which may be incident to the use of the improvements, the invention consists in the parts and combinations thereof hereinafter set forth and claimed, with the understanding that the several necessary elements constituting the same may be vafied in proportions and arrangement without departing from the nature and scope of the invention.

In order to make the invention more clearly understood there are shown in the accompanying drawings means for carrying Serial No. 444,463.

the same into practical effect, without limitin; the improvements. in their useful applications, to the particular construction which, for the purpose of explanation, have been made the subject of illustration. In the said drawings:

Figure 1, is an end elevation, looking at the right-hand side of the machine, of a paper feed mechanism embodying my improvements.

Fig. 2 is a rear elevation of the same.

Fig. 3 is a front elevation.

Fig. 4 is a partial rear elevation from the line X X of Fig. 1, showing certain parts which are not plainly shown in Figure 2 and omitting the spring 30.

In the drawing a showing of the listing adding machine and its mechanism is not necessary to a clear understanding, of my invention, and the same may be of any suit able character. and I have confined the illustration to'the paper feeding mechanism.

deferring to the drawing, 1 is the paper feeding roll and platen having a shaft or journals 2 mounted in a suitable paper carriage C adapted to traverse horizontally. and transversely of the machine behind the printing type. the latter having a rearward printing movement against the paper 3. 4 is a ratchet attached to the feed roll 1, which ratchet is actuated in the direction shown by the arrow. and with a step by step movement by a pawl 5. Said pawl is pivoted at 6 on a rearwardlv and forwardly rocking lever 7,

this lever being pivotally mounted on the journal 2. The pawl is pressed towards the ratchet by a spring; 8, and at the end of the rearward actuating movement of the lever 7 the pawl is lifted away from the ratchet by a cam 9 fixed on the frame of the carriasrc, and on which rides a pin 10 of the pawl.

This disengagement takes place just at the end of the feedinc of the paper up fora distance equal to the space between lines of printing. On the forward movement of the lever 7 the pin 10 rides downward and inward on the fired cam, and the pawl takes one or more teeth of the ratchet for the actuation of the latter.

The leveris rocked by a link 11. whose forward and backward movement is limited by front and rear stops 12, 13. fixed on the carriage frame. This link has a pin 14 which engages in a slot 15 of the lever and. is reciprocated by a pin 16 which normally 11 and lever 7 forward, and the pawl 5 rides ward,

downward and inward on the fixed cam and engages the ratchet ready for a paper feeding actuation. The printing havin taken place, the crank handle is returned backthe angle lever and lever 7 rocked backward, and the pawl 5 turns the paper feeding roll from the printed line to the nextline. 22 is a cam pivoted at 23 on the angle lever, and movable forward and backward at will by means of a manipulative pin 24 fixed on the cam and extending to the right hand side of the machine. One end of this pin works in a. slot '25 of the arm 18,

whereby the movement of the cam is limited.

- The cam is held. but so as'tolyield to manipulation, in either position, by a sprlng dog 26 which can bear on the front side 0t the pin 24 to hold the cam 22 in its rearward position, and can bear on the rear side of the pin to hold the cam in its forward position.

the pin by tail of the dog with the' pin 16. but so as to be yieldable when the pin 24 is manipn' lated, this being accomplished by making the dog with inclined faces to bear on'the pin as described above. The further action. of this spring is to press the pin 16 downward and the link 11 and lever-7 rearward. When the cam 22 is in its rear positio'n, the pin 16 may rest in the fork-17', and the paper will be automaticallyjd as above set forth, but whenthe camss adjusted forward, the pin 16 will ride upon the cam and be removed from connection with the angle The dog 26 is pressed towards lever. This upward movement "of the pin will slightly lift the-reap end of the link 11, andthe pin will of the arm, so that the arm and slot will play idly along the pin, the slot 1'7 being temporarily obliterated for operative purposes by the cam 22.

In this last described position of the parts printing may be performed at the seycral desired columns or places of the same; line of the,paper. This'isdone by the aid of a, transverse tabulating movementoo the. carriage; in a-known mauu'eravnich does not require to" be"furt-her described, but without any line to line feed-of thgpaper; In order to provide for difierent degrees of rotation of the feed roll. the link 11 is adjustable up and down at its forward; end

the pin 14 being correspondingly adjustable a spring 27, which connects the remain within a slot 28' in the slot 15. When the pin is in the upper,

part of the slot, a shorter automatic feed of the paper W'lll take place, causing the llnes to e printed closer together, and when the pin is no the lower part of the slot and tie nearer to the center of rotation of the ratchet, a longer feed will be caused and lines will be printed further apart. The pin may be maintained in various parts of the slot, as may be desired. I have shown means for holding it in-two positions, comprising a dog 29 loosely piyo ted on the journal 2.

the upper or lower inclined face of which dog is pressed against the pin by a. spring 30 which connects the tail of the dog with a hook 31 on the lever '7. The dog will thus brace the pin up from below or will'hook over above it. but will yield when thelink 11 is adjusted vertically by a manipulative button or forwardly extended arm 32.

When the automatic feed is held discounected by the cam 22 the feed roll'may be turned backward or forward by hand by the usual finger buttons' or heads 33 which are fixed on the outer ends of the journals 2, and the roll may be maintained in the position to which it is adiusted by the usual star wheel fixed on the left hand journal and a spring actuated roller engaging between the points of the star wheel.

When successive lines are to be printed with two or more items in each line. it ma be convenient just before. the adding chine handle is actuated for the printing of the last item of a line. to throw the cam 22 rearward. whereupon the printing of the last item will be followed by an automatic feed of the paper. Tben' the cam will be thrown back forward byhand and the car riage will be returned to' the right. and a new line will be printed without any rm;- ther upward feed of the paper. orthe paper may be fed "from line to lineby hand. withmanual feed will be hy means of the handle 34a furnished bvthc upper eud'ht thelever' 7 which, will he rcciprocated forward and backward to accomplish the paper feed from the printed line to the new line. On the same movement of the hand. the carria e may be returned to the right. 4

1 35. is a lip on the'dog 29 which is adapted to engage with a art of or pro'je 'itionv on the lever 7 Where y the dog iskept from constantly pressing'onthe pin 14. which would cause friction and wear. When the lever 7 is moved rearwardly it causes the pin I 14 tohave a tendency to move downward in the slot 15, especially if the platen ofi'ers much resistance to turning'j To overnome this a torward ro 'ection 38 is provided on the link 11 whic is arranged to be normally above the stop 12 (Fig. 1). so that any downward pressure on the link 11"is prevented until the rearward movement has been started, and after the projection 36 is disengaged from the stop 12 the force component tending to move the pin 14 down- Ward will have disappeared. The link 11 has a yoke formation seen in Fig. 2, whereby it embraces the members 18 and 22 and maintaining the link in alineine'nt with the different connected parts, so as to insure its satisfactory manual operation by the handle 32. The members 18 and 22 are suitably offset, as seen in .Fi 2,.and the cam 22 is provided with a hub 37 for rendering 'its'operation more reliable. The lever 19 is fastened on the shaft 23 by a bent portion 38, which is spot-Welded thereto.

It will be understood that my invention contemplates the forming of the slot 28 in the link 11 and fixing the pin 16 on the arm 18, such construction having substantially the same mode of operation as that which I have illustrated.

It Will be understood that the carriage is provided with an arm 19 at each end, the two arms sustaining the bail 20. 39 is a hub on the lever 7 to support and space the same on the platen shaft What I claim is l. A paper feed mechanism for adding machines and the like, having, in combination: a paper-feeding roll, a ratchet uttached to said roll, a pawl for turning the ratchet, devices operated by a movable part of the adding machine for reciprocating the pawl, said devices being adjustable to vary the throw of the pawl, and manipulative means which is separate from and in0perative of other parts of the adding machine for disconnecting said devices at will so that operations of the adding machine may -be performed with two.'or more printingson/ the same line Without any feed of the papei: by said roll,-said disconnection leaving the roll free for turning by hand.

2. The combination of a paper feed roll, a ratchet attached thereto, a tabulating carriage carrying said roll, a lever mounted on the carriage and turnable relative to and with the ratchet, a awl on said lever adapted to turn the rate et, a fixed cam controlmachines -Ieeding devices and having its point ling said pawl, a lever arm which is swing able towards and from the lever on the ear- -riage, a link connected with said lever and extending to said arm, manually operative means for connecting and disconnecting said link and arm, and means whereby said arm ma be operated by the mechanism of the" ad ing and recording. machine.

3. In a paper feed mechanism for adding machines and the like, the combination of paper'holding and feeding devices, means for adjusting said devices for variable distances of feed, means for actuating the actuating means comprising a notched arm operated by the adding machine mechanism and a pin connected With the paper feed devices and said disconnecting devices comprising means for covering the notch of said arm whereupon the pin may ride thereover.

a 4. In a paper-feed mechanism for adding and the like, the combination of paper-holding and feeding devices, an actuating element of the adding'machine, and an arm the forward end of which is adjustable relative to the paper-feeding devices to vary the length or" of which arm is connectable with said actuating element for the operation of the paperfeed and disconnect-able from said actuating, element for the cessation of the paper feed.

5. In a paper-feed mechanism for adding machines and the like, the combination of rotatabi papenholding and feeding devices,-an actuating element or the adding machine, an arm connected with said papen of con nection adjustable towards or from the center of rotation of the paper-holdingmeans, and means whereby said arm is con nectable and disconnectsble with said actuating element.

In testimony whereof I aiiix my signature.
