Claims. (01. 191-129) reccrd is'wasted. The present mechanism is, v
therefore, provided for feeding only that portion of the platen which is inoperative relation with the printing type bars during that operation.
The present improvement is also adapted to operate to accomplish the above result when used in combination with a selective feeding control that allows the feeding mechanism to operate 2 only in predetermined columnar positions of the paper carriage.
With these and incidental objects in view, the invention consists in certain novel features of construction and combinations of parts, the. es-
sential elements of which are set forth in appended claims, and a preferred form of embodiment of which is hereinafter described with reference to the drawings which accompany and form part of the specification.

General description The present mechanism is shown applied to a key set, motor actuated accounting machine having a traveling paper carriage with suitable con- 5 trol lugs on the rear thereof. The present mechanism is shown as applied to the machine fully disclosed in my application for United States Letters Patent Serial No. 581,800, filed December 18, 1931, and is an improvement over the mechanism disclosed in United States Letters Patent No. 1,708,284 issued to Oscar J. Sundstrand.
Detailed description A laterally movable paper carriage indicated generally at I (Figure 1) is mounted on a rail 2 through anti-friction rollers 3. It is moved from left to right (Figure 3) in its working stroke, and is stopped in the several tabular columns indicated, by suitable tabulating mechanism de- 30 scribed in the above mentioned application. A suitable carriage return also described in the above mentioned application returns the carriage to its right hand position. While the can'lage is stopped in each of its columnar positions, the 35 machine is operated to perform the necessary accounting functions and to print the proper entry on one of the record sheets. To perform these operations a main actuating shaft 4 (Figure 1) is oscillated, first counter-clockwise to the posi- 40 tion shown in Figure 1, and then clockwise to its home position.
In the operation of shaft 4, an arm 5 secured thereto, through a roller t, oscillates a pelican lever I pivoted at 8. Operation of lever I raises 45 and lowers a link il pivoted to the lever to a bell crank i2 pivoted at It. The movement imparted to link ll first oscillates bell crank lf clockwise to the position shown in Figure 1 and then counter-clockwise to its normal position. 50
is-tensioned clockwise by springs 2| and 22 (Figures 1 and 4) fastened to laterally extending cars 23 and 24 on the forward ends oi. plates l1 and I6. Clockwise movement of the cradle is limited 5 by roller l4.
pivoted to plates i1 and I6 .and have their forward ends tensioned upwardly by springs 21 and 28 attached to the rear ends of the fingers and to levers 3| and 32, also pivoted on plates l1 and 10 iii. For the purpose of the present disclosure,
levers 3| and 32 may be considered only as anchors for springs 21 and 26. The position of levers 3| and 32, under the tension of springs 21 and 23, is determined by rollers 33 and 34 bearing against the under side of plates I1 and |6. Spacing wheels 35 and 36 are secured near the outer ends of the platen shafts?" and 36 (Figure 3) individual to the two parts-of the platen and lie in the same vertical plane with spacing fingers and 26. Movement of these spacing wheels rotates their respective shafts and thereby advances their respective record sheets, the movement of one spacing wheel and platen having no effect on the other spacing wheel and 25 platen. The details of construction of the platen shafts and the manner in which the platens are secured thereto may be similar to the construction disclosed in United States Patent No. 1,708,284, or No. 1,880,220.
By the above described parts, the initial clockwise oscillation of bell crank |2 (Figure 19 moves roller H to the rear, allowing springs 2| and 22 to rock the cradle to the rear and move the forward pointed ends of fingers 25 and 26 to their cocked positions, as illustrated by finger 25 in Figure 1. The ensuing counter-clockwise movement of bell crank |2 returns the cradle to its normal forward position, causing the forward ends of the spacing fingers 25 and 26 to rotate spacing wheels 35 and 36 a distance sufilcient to line space the paper. Toward the end of the return movement,- ears 23 and 24 contact the upper edges of the spacing fingers, causing the fingers to be moved out of contact with the spacing wheels for the remainder of the movement.
As it is desirable to have the line spacing mechanism operate only in certain tabular positions of the carriage, the following parts are provided to disable it at certain times. Referring to Figure 6, a. carriage operatedlever 4| is pivoted at 42 to a stationary part of the machine and has a roller 43lying in the vertical plane of control lugs such as 44 carried by suitable supportmg magazines such as 45- on the rear of the paper carriage. A rod 46 extends between the "under side of lever 4| and the rear arm of a lever 41 pivoted on a rod 46 and connected to a link 5|. Link 5|, is pivoted to the forward end of an 1. arm 52 secured to a shaft 53 joumaled in stationary' part of the machine. Link 5| is held in its'lower position, and rod 46 and lever 4| in their upper. positions, by a spring 54 connected to link 5| and to a. stationary part of the ma- 65 chine. A blocking arm 55 extends forwardly from shaft 53 and lies directly behind rod l6.
By the above described parts, rod I6 is held in its forward normal 'position when the parts are in the positions shown in Figure 6, so that 70 oscillation of hell crank l2 (Figure 1) during the operation will be ineffective in allowing spring 2| to move spacing fingers 25 and 26 to the rear to place their forward ends in a position to advance the platens. However, when the carriage 75 moves into one of its columnar positions where Line spacing fingers 25 and 26 are line spacing is desired, 9. lug 44 depresses roller 43, depressing rod 46 and raising the blocking arm 55 about rod l6. Now upon the ensuing operation, rod I6 is free to move to the rear and thereby enable the spacing fingers to advance 5 the platens.
Another means is provided, as mentioned above, to allow line spacing of only that part of the platen lying in operative relation with the print ing type during that operation. This means in- 10 cludes bell cranks 56 and 51 (Figures 1 and 4) pivoted to the carriage at 6| and 62 and carrying rollers 63 and 64 on their upper arms. Two levers 65 and 66 are also pivoted on the carriage at 61 and 63 and carry flanges II and 12 to support 15 the forward ends of spacing fingers 25 and 26 against side play. Short studs 13 and 14 extend inwardly from flanges II and i2 and lie in the vertical plane of fingers 25 and 26. Springs I5 and 16 are connected to the forward ends of levers 20 65 and 66 and to the carriage to tension studs 13 and i4 downwardly, and rollers 63 and 64 rearwardly. By comparing Figures 1 and 4, it will be noticed that the forward edge of carriage rail 2 extends a short distance into the path of rollers 25 63 and 64 so that when the carriage is shifted in one direction or the other, the rollers are forced forward as soon as they reach the rail. As shown in Figure 1, when one of the rollers has been forced forwardly by the carriage rail, stud I3 is 30 elevated out of the path of finger 25 so that it will not affect the operation of the spacing finger during that operation. However, when movement of the carriage causes one of the rollers to leave the carriage rail, stud I3 or I4, as the 35 case may be, is lowered sufllciently to prevent the forward end of its associated spacing finger from moving into operative contact with the, corresponding spacing wheel, as illustrated in Figure 5. Now, even though the cradle is permitted to move 40 to the rear for line spacing during this operation, this particular spacing finger will be ineffective to advance its part of the platen.
By referring to Figure 1, it will be noticed that as long as the right hand part of the platen is 45 opposite the printing type, roller 63, associated therewith and lying approximately behind spacing wheel 35, is in contact with the carriage rail, whereas roller 64 for the left part of the platen is out of contact with the rail, and as soon as 50 the left half of the platen is moved into operative position with the type bars, roller 64 is moved into contact with the rail and roller 63 out of contact therewith. By this arrangement, only that part of the platen in operative position with the 55 printing type will be line spaced under control of the carriage lugs 44.
While the form of mechanism .herein shown and described is admirably adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form of embodiment herein disclosed for it is susceptible of embodiment in various forms all coming within the scope of the claims which follow.
