PAUL V. GILFILLAN, OF WEST PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO UNDERWOOD TYPEWRITER COMPANY, OF NEW YORK, N. Y., A CORPORATION OF DELAWARE.

TYPE-WRITING MACHINE,

Specification of Letters Patent.

Patented Aug. 31, 1915.

To all whom it may concern-.-

Be it known that 1, PAUL V. GILFILLAN, a citizen of the United States, residing in Vest Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improve ments in Type-Writing Machines, of which the following is a specification.

This invention relates to attachments for typewriting machines, particularly adapted to facilitate the rapid and accurate placing of bills or other work forms on the platen in position to be written upon.

In making typewritten entries on a series of forms such as telephone bills and the like, where the amount of typewritten matter on each form is small, a comparatively large proportion of the time required 1n such work is consumed in placing the forms on the machine and positioning them to be written upon.

An object of the present invention is to provide a contrivance for a typewriting machine whichl will enable the Work forms to be quickly and accurately positioned on the platen, thus resulting in a material saving of time where very many bills are to be placed serz'atz'm in the machine and each is to receive only a little writing.

The attachment may be in the form of a chute or guide placed in. rear of the platen,

. and extending beneath and around the platen to the printing line, and positioned and spaced from the platen by suitable means, such as rings secured to the platen to hold the guide a suflicient distance from the platen to permit a work member to be slipped between the guide and platen, and thus quickly brought to printing position, where it may then be held by pressure rolls (which are released from the platen while the work is being introduced).

Other features and advantages will hereinafter appear.

In ,the accompanying drawings, Figure 1 is a front perspective view of an Underwood platen and frame, with the present invention applied thereto. Fig. 2 is a skeleton perspective view showing the paperguide or chute, and the rings for positioning said chute relatively to the platen. F ig. 3 is a sectional end elevation View through the platen and paper-guide. Fig. 4 is a fragmentary sectional front elevation.

A rotary platen 1 is fixed to a platen axle 2 journaled in the ends 3 of the platen frame, which may also comprise the usual inclined paper shelf 4:, located at the rear of the platen and connecting the platen frame ends. A chute 5, by means of which'a bill or other work member is guided to position to be written upon, comprises a body portion 6, which lies over the paper shelf Land may be held in position by any suitable means, as bolts 7. The lower portion of the chute is curved to conform to the curved surface of the platen, and extends "downwardly beneath the platen and up toward the printing line, the front edge 8 forming a gage for the printing line.

The chute 5 is spaced from the platen to gages to engage the opposite lateral edges of the work members, to confine them againstdisplacement, and bring them accurately to printing position. Flanges 15 extending along the edges of the flat portion 6 0f the chute also serve as side gages fo the work members.

When a work member has been placed on the chute 5 and slipped forward to printing position and adjusted to the platen scale 8, it may be clamped by feed rolls 16, mounted upon a swinging rod 17 carried by rock arms 18 journaled on a rod 19 extending between the ends of the platen frame. The

feed rolls are yieldingly held against the platen by springs 20, and may be lifted from the platen by means of rock arms 21 secured to the arms 18 and actuated by cam faces 22, on a rock shaft 23, actuated by a finger lever 24 connected through a link to an arm 26 on the shaft 23. The lever 24 is depressed prior to the insertion of a work member, to lift the feed rolls from the platen, the rolls remaining in such position when pressure on the lever 24 is removed, and after the work is in position, said lever is returned to restore thepressure rolls and thus clamp the work in position. The work, may be additionally held by a Y-shaped spring clamp 27 secured to the rod 17 and extending within a notch or opening in the scale 8, and movable toward and from the platen together with the feed rolls. This form of clamp is in commonuse on the Underwood typewriting machine.

The chute 5 is cut away at 28 to provide space to accommodate the feedrolls, and the edges 29 above said spaces 28 are preferably beveled or turned outward, as shown, to prevent the edge of the Work sheet from catching thereon.

It will be seen that the present invention provides a means for quickly and accurately bill, or other work form,

quick removal after it has been written upon. This is of special value in making entries upon a series of Work forms of uniform size, such as telephone bills, and the like, where the amount of writing on each bill is comparatively small, and the rapid insertion and removal of the work members results in a material saving of time when a long list of such bills is handled. The chute 13 is entirely clear of the platen, so that a sheet may be freely positioning the on the platen, and permits slipped around the platen to printing position when the feed rolls are cast off.

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

Having thus described my invention, I claim:

1. The combination with a rotary platen, of a paper guide or chute curved to conform to the periphery of the platen, and means on the platen for spacing said chute therefrom to permit a work member to be slipped into position between said chute and the platen.

2. The combination with a rotary platen, of a paper guide or chute curved to conform to the periphery of the platen, and rings secured to the platen in position to space said chute from the platen.

3. The combination with a rotary platen, of a paper guide having a portion curved to conform to the periphery of the platen, and rings secured to the platen and provided with flanges between the platen and the edges of the said guide to space the guide from the platen.

4. The combination with a rotary platen, of a paper guide comprising an inclined shelf having flanges along its lateral edges to gage a work member,'and a curved porthe introductory side of the platen and ex tending forwardly around the platen about The combination with a rotary la i I to the printing line, and spaced from the platen to permit the work-sheet to he slid between the platen and said-guide to-position to be written upon, and lateral guiding means for the work-sheet at each side of said stationary guide to guide the sheet both near the printing line.
