7 To all whom it may concern:

Be it known that I, LESTER A. WERNERY, a citizen of the United States, residing in Brooklyn borough, in the county of Kings, city and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

This invention relates 'to appliances for typewriting machines, and, in the form herein specifically disclosed, is particularly adapted for advancing over the platen a-work sheet or web, consisting of a series of workforms adapted to be written upon seriatz'm. The work sheet or device may consist of a number of blank forms connected in a continuous web or long sheet to be advanced over the platen to bring the blank forms sedatim into position to'be written upon. A feature of the invention is the provision of improved means for quickly and accurately advancing each form into position to be. written upon, when the entries on the preceding-form have been completed. In the preferred embodiment of the invention, a handle or driver is provided having a limited throw and means cooperating therewith, for advancing the work member to bring a new form into position to receive the first line of writing whenever the driver is actuated to the limit of its forward movement, regardless of the extent the platen has been rotated while entries were being made upon the preceding work-form.

The driver may be a crank loosely mount-- ed on the platen axle and its movement in both directions limited by stops, one'or both of which may be adjustable to limit the throw of the driver. The driving connection between the driver and the platen may be eflected by means of a coupling device, which, in the form disclosed, comprises a dog on the driver adapted to engage the' teeth of a ratchet wheel'which rotates with the platen. A coupling controller or gage which may be in the form of a disk loose on the platen axle but which may be caused to rotate therewith by frictional engagement, or other appropriate means, lies in the path of the dog and thereby holds the latter out ofengagement with the ratchet wheel dur' ing the rotation of the platen independently of the operation of the driver, said disk Specification of Letters Patent.

Application flied March 27, 1914. Serial No. 827,589.

-turnin with the platen during such rotation. 0 advance the completed'work-form into position to be removed and .to bring a succeeding work-form into position to be printed upon the driver is swung forward, and during its initial movement, the dog thereon rides idly on said disk, until a notch in the disk permits the dog to spring into engagement with the ratchet wheel so that during the final movement of the driver the platen is rotated therewith. The position of the notch at the time the driver is swung forward to engage the ratchet wheel depends on the distance the platen has been rotated during the writing upon the work-form.

The extent the 'platen is rotated by the the total movement of the platen being determined by the .total throw of the driver, which is adjusted to' the length of the individual work-form. The driver may be returned to initial position by a spring, and a lug on said disk, in front of which the dog drops as it enters into said notch, forms a driving connection between the driver and the disk for returning the latter with the driver. As the driver completes'its return movement, the dog may be lifted by a cam to disengage said lug, thereby releasing the disk readyfor a subsequent operation.

Other features and advantages will hereinafter appear; and the invention may be used for other purposes. v

In the accompanying drawings,

Figure 1 is a front perspective view showing the platen frame and platen of an Underwood typewriting machine with the present invention attached thereto.

Fig. 2 is a sectional end elevation showing the parts in the position assumed when- Fig. 5 is detail View of the driving dog.

Fig. '7- is a disassembled view showing successively the ratchet wheel, the friction member, the interponent disk between which and the ratchet wheel .said friction member is arranged, and a hand wheel.

A rotary platen.1 is fixed to an axle 2 journaled in the ends 3, 4 of the platen frame, said ends connected by an inclined paper shelf 5 at the rear of the platen. The platen may be rotated either by hand wheels 6 on the ends of the platen axle, or by the upon, the platen may be further rotated to bring the next'form into position by means of a driver 13 which as herein shown, comprises an arm extending radially from a disk 14 loosely mounted on the platen axle 2, said arm provided at its outer end with a handle 15. A coupling device to establish a driving connection between the driver and the platen is provided, and comprises, in the form disclosed, a ratchet wheel 16 and a dog 18. The ratchet wheel 16 is fixed to the platen axle as by means of a pin extended through the hub 17 of said wheel and through the said axle. A dog 18 slidably mounted on the driver 13 is formed with a beveled tooth 19 to engage the ratchet wheel 16 to drive it in a forward direction,

, but permits forward rotation of the platen independently of the driver. The dog 18 comprises a neck 20, extending through an elongated slot 21 in thedriver, and a plate 22 having a slot-and- pin connection 23, 24, with the driver. A stem 25 on the plate 22 is guided in a lug 26 on the driver 13, and a spring 27 surrounding said stem between the lug 26 and the plate 22 moves the dog 18 radially inward to engage the ratchet wheel 16.

An interponent between the dog and ratchet wheel 16 for holding the dog off the ratchet wheel is shown in the form of a disk 28 having a hub 29 loosely mounted on the hub 17 of the ratchet wheel, and said disk is substantially of the same diameter as that of the ratchet wheel, so that the periphery of the disk engages the tooth 19 of the dog 18 and holds the latter out of driving engagement with the .ratchet wheel, except when said tooth is brought into position to enter a notch 30 in the disk and thus connect the driver with the ratchet wheel. The disk 28 thus constitutes a gage or coumeat 4e pling controlling device for determinin the point at which the couplingdevice sh 1 become efi'ective during the advance'movement of the driver. The hub 29 on said disk is frictionally held against the hub of the adjacent hand wheel 6 by. means of a sprmg, shown as a c'onvexed sheet metal ring or disk 31 of resilient material, interthe disk 28 and the ratchet and extending outwa dly from a disk 36 loosely mounted on the platen axle between the driver disk 14 and the ratchet wheel 16. Within the tube 33 is a holding pin or bolt 37 adapted to enter any one of an annular series of openings 38, in the disk 34, thereby holding the stop 33 in any desired position relative to the stop 32. The openmgs 38 may be spaced at line-space intervals. The bolt 37 may be withdrawn by a knob 39 against the tension of a spring 40; v

housed in the tube 33 and bearing against a collar on the bolt 37. p

The driver 13 is normally held against the stop 32 by means of a returning spring 41 shown as a coil spring, housed within the space provided by recessing the opposing faces of. the disks 34, 14, one end of said spring secured to the disk 34 and the other end secured to the disk 14. Whenever the driver 13 is returned to starting position (Fig. 2) the disk 28 is carried with it, being connected to the driver by a lug or detent 42 on the outer face of the disk in the path of an overhanging lip 43 projecting beyond the tooth 19.

The operation may be summarized as follows:

The worksheet or web comprising, for example, a series of printed forms or blanks is placed on the machine and the first form positioned to receive the first typewritten entry. The driver 13 and interponent disk 28 being at the starting position shown in Fi 2, the desired entries are now typewrltten upon the work-form, during WhlCll operation the platen is rotated by the linespace lever or the hand wheels 6, a greater or less extent depending upon the required entries on the work-form. During such rotation of the platen, the driver 13 remains at rest, the tooth 19 being held free from the ratchet wheel 16 by a cam surface 44 on the disk 34, which surface, as the driver was returned to starting position (Fig. 2) engaged a shoulder 45 on the locking dog and lifted the latter free from the ratchet wheel moved, if desired.

It will be noted that as the platen is rotated prior to the operation of the driver the disk 28 is carried with it and rotated a variable distance determined by the position to which the work-form has been brought by the time the typewrittenentries thereon have been completed. The entire distance however, through which the platen is rotated, determined-by the throw of the driver, 13, is constant. In \other words, the distance the platen is rotated by the driver is complemental to the distance it'is rotated prior to the operation of the driver and the sum of these distances is measured by the distance between the stops 32 and 33. These stops may therefore be set for work-forms of any length within the range ofothe mechanism, so that each time the driver is actuated, a new form. is fed into position for receiving the first line of writing. When the tooth 19 enters the notch 30 during the forward movement of the driver, the lip 43 moves inward in front of the lug 42, so that when the handle 15 is released and the driver returned by the spring 41, the disk 28 is carried with it until the shoulder 45 rides on to the cam face 44 as the driver completes its return movement. Thus the disk 28 is always returned to the same starting position. During the return of the driver, the tooth. 19 rides idly over the ratchet wheel, so that the platen remains at rest. The teeth on the ratchet wheel do not throw the dog out a suificient distance during such return movement to free it from thelug 42.

Varlations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
