PAPER TAKE-UP FOR TYBEWRITING MACHINES.

APPLICATION FILED JAN- 5, I920.

To all whom it may concern:

UNITED STATES PATENT OFFICE- PAPER TAKE-UP FORJTYPEWRITINWMACHINES.

Be it known that I, DANIELUGARDNER, a

citizen of the United States, residing at N ew-.

burgh, in the county of'Orange and State of New York, have invented certain new and useful Improvements in Paper Take:

Ups for Typewriting Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention consists in the novel features hereinafter described, reference being had to the accompanying drawing which illustrates one embodiment of the same, selected by me for purposes of illustration, and the same invention is fully disclosed in the following description and claims.

In the use of typewriting machines, especially with manifolding work in which a number of sheets of paper and one or more sheets of carbon are placed in the paper (grriage, and are fed up step by step by the line feeding mechanism, itfrequently happens that an unequal feed of the sheets of the different layers, or a twisting of the multi-sheets with respect to the axis of the feed roll, or other shifting of the paper and carbon sheets .with respect to each other, results, causing inequalities in the writing on the different sheets and differences of alinement, which are extremely objectionable, and also necessitating in some cases the removal of the sheets from the carriage and the replacing of them in the carriage, which can seldom, if ever, be effected without disarranging the paper sheets with respect to each other, and affecting the alinement of thework. The object of my invention is to provide in connection with the paper carriage of a typewriting machine, a simple device which can be permanently or detachably secured thereto, and which comprises among its members, a light-frame extending I above the paper roll, a paper clamp for engaging the upper edges of the sheets, a flexible connection connected to the paper clamp at one end andhaving its other end connected to a continuously acting take-up, prefer-' ably in the form of a spring drum carried by the frame. With this apparatus the op erator, after inserting a series of sheets in the feed mechanism on the paper carriage, can draw forward the paper clamp, and

clamp it upon the upper edges of the com- Specification of Letters Patent.

bined sheets, and preferably centrally thereof, when the tensioning device will immediately act through the flexible connection to exert an upward pull on the combined sheets at all times during the writing. As the paper is spaced vertically by the line feeding mechanism, the take-up mechanism continues to exert an upward draft on the combined sheets equally during, before, and after, the line spacing feed of the paper, thus assistingthe paper feeding mechanism to feed the combined sheets in a perfectly straight vertical manner and preventing any movement of the sheets with respect to each other, or any tendency of the sheets to feed faster at one edge than at the other, or to otherwise shift their relation with respect to the feed roll.

Referringto the drawings, Figure 1 represents a perspective view of one embodiment of my improved paper ten sioning device, thidjacent portions of a typewriting machine being indicated in dotted lines and the position of the paper clamp and flexible connection in conjunction with the paper sheets being indicated. in dotted lines also. r

Fig. 2 is a side elevation of my improved device.

Fig. 3 is an enlarged section of the same through the spring actuated tension device, parts being shown in elevation.

In the embodiment of my invention herein shown, 1 represents a narrow frame bar provided at one end with means for securing it to the paper carriage of a typewriting machine. In the present instance, I have shown the lower end of the frame bar 1. provided with clamping jaws 22 for clamping the upper edge of the paper guiding plate A at the rear of the paper feed roll B of the type writing machine, the jaws being held in engagement with said plate (or other portion of the paper carriage) in any desired way, as bythe clamping screw 3 and wing nut 4 herein shown. 5 represents a paper clip which comprises merely a pair of gripping jaws normally held in gripping position by a suitable spring 6 in a well known way, one

of the jaws being provided with a thumb consists of a spring actuateddrum 1O mounted in arms 11, secured to the rear face of the frame 1,-said drum being rovided internally with a sslrin 12, whic acts at all times to rotate e drum in the direction indicated by the arrow in Fig. 1. I prefer to connect one end of the spring 12 to the drum and the other end to a shaft 13 provided with a ratchet 14 engaged by apawl 15'carried on one of the arms 11, and to provide the'shaft 13 with a pol gonal portion 16 so that it can be turned by means of a key or other suitable tool to adjust the tension of the spring, in a Well known way.

When the apparatus is atrest the paper clip 5 will be held at the upper end of the bar or frame 1, out of the way, and the apparatus will not interfere in any way with the operation of the typew-riting machine. When it is desired to do manifolding, a plurality of paper sheets and carbons is inserted around. the feed roll B and the operator will reach forward, grasp the paper clamp by the base and thumb piece, so as to open the clamp, and drawing on the flexible connection 8, will apply the clamp-to the top edges of the combined paper sheets, thus holding them firmly in proper relation with each other, and causing an upward tension to be exertedupon the paper sheets by the spring drum through the flexible'connection 8. As will be apparent, the spring drum-will exert a constant upwar pul on the paper sheets so long as they remain in the machine, and as the pa er carriage is operated for line spacing, tiie tension device will take up this space and assist in effecting a perfectly vertical feed of the paper as well as a perfectly uniform feed of all the sheets or layers of paper and carbons, thus preventing any tendency of the paper to twist with respect to the roll, as well as any tendency oft he paper and carbon sheets to shift in any manner with respect to each other. This simple and compact device-will be found to be very advantageous in securing proper feeding of the paper in type writing machines, especially in manifold work, although it may obviously be used in connection with single sheets and will be found extremely advantageous in many cases in connection with single sheet work, especially in handling heavy backing sheets, manuscript covers, and the like.

When the paper has been fed as far as the feed mechanism of the typewriting machine will feed it, it will be held suspended by the paper clamp 5 until the operator releases it, by depressing the thumb piece 7, thus retaining the sheets in proper relation with each other even after they have left the control of the paper feeding mechanism of the typewriter. i e

What I claim and desire to secure by Letters Patent is 1. A paper take-up attachment for typewriting machines comprising among its members a paper clamp for engaging the topmost edge or edges of a paper sheet or sheets, a continuously acting tension device, and a flexible connection from the tension device to said paper clamp.

2. A paper take-up attachment for typewriting machines comprising among its members a frame bar provided at one end with means for attaching it to the paper carriage of a typewriting machine, a continhlously acting tension device, a paper; clamp, and a flexible connection from the tensioning device to said paper clamp.

v 3. A paper take-up attachment for typewriting machines comprising among its members a frame bar provided at one end with'a clamp for attaching it to the paper carriage of a typewriting machine, and having a pulley .at the other end, a continuously acting spring actuated drum carried by said frame-bar, a paper clamp for engagingthe upper edge or edges of a paper sheet or sheets, and a flexible connection having one end secured to the paper clamp and the other end secured to said drum and passing over said pulley.

In testimony whereof I aflix 111 Si nature.

DANIEL GA D ER.
