TYPEWRITING-MACHINE AND SUPPORTS THEREFOR.

Specification of Letters Patent. Patented June "Z, 1921.

Original application filed June 21 1917, Serial No. 175,996. Divided and this application filed May 17, 1920. Serial No. 382,166.

To all whom it may cmwern:

Be it known that I, Jesse A. B. SMITH, a citizen of the United States, residing in Stamford in the county of Fairfield and State of Connecticut, have invented certain newand useful Improvements in Typewriting-Ma'chines and Supports Therefor, of which the following is a specification.

This invention relates to an improved typewriting machine for writing manifold-- form letters, and an improved machine support therefor. i

In my prior Patent No. 1,237,716, dated August 21, 1917, on which this is an improvement, the web, comprising several layers of work-sheets, .was interleaved with carbon-sheets and fed to the platen. The web I was continuous and preferably provided with printed forms, each constituting one piece of work which, when completed, was

torn off from the continuous web. The interleaved carbon-sheets were mounted on a carriage, so as to feed with the web while t pewriting, but capable of being withrawn relatively to the web, so as to enable the bringing of a fresh portion.

of the web in register with the carbonsheets, thus enabling the same carbon-sheets to be used repeatedly for a Iiumber'of letters. In this way, a large number of form letters could be written, with several copies of each letter,by using one set of carbonsheets and a continuous web comprising several folds or layers.

In' the patent to dated-August 21, 1917, it was shown how the carriage, 011 which the carbon-sheets were mounted, was formed in two parts, so that a portion .on which the carbon-sheets were directly mounted could be detached from the body of the carriage, thus enabling the web and the carbon-sheets to be detached and the typewriter used without that particthe carbon frame for the lower web in place ular web.

In this present invention, there are provided a plurality of carbon-sheet-supporting frames, two being shown. These supchanging the webs, the machine, per so, is

Fortin, No. "1,237,319,

'may be placed, and from which they may be fed over the carbon carriage and its frame to the typewriter carriage and its platen. There is provided one of the carbon-framecarriers for each web, and they are of the detachable form, so that one may be interchanged for the other on the carbon carriage proper.

The drawers, storing the webs, are inclined slightly, .so that the webs can be drawn off, layer bylayer, without disturbing the under layers. Betweenthe upper and lower drawers, a guide-rail is provided, so that the lower web may clear the upper web, as the carbon frame for the up er web can most conveniently be rested rlght in back of the machine frame, above the tier of drawers.

When in use, the drawers are held in a- The struts-are of graded size,-

lower drawer will projectfarther to the rear of the upper drawer. These struts are pivotally mounted so that they can be swung aside to permit the drawers to be shoved in under the top of the table out of the way.

No claim is made herein to my improved machinestand or support, per se, claims to such invention havin been made in my prior application, Serial fie 175,996, filed June 21, 1917, of which this case is a division.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a perspective view, looking at it from the rear, showing the carbon frame for the upper web'as detached, and

position on the machine for writing, and' this web comes from a pack 8, located in the lower of a plurality of drawers 9 and 10.

The upper drawer 10 carries a pack 11 of the web 7, which is connected to the carboncarrying frame 5. The drawers 9 and 10 are slidingly mounted in guide-ways 12 and 13, so that they can be removed from the table, if necessary. 3

It will be noted that these drawers are inclined slightly downward and forward, so that the upper layers of the webs can be drawn off without disturbing the lower layers. Between the upper web 7 and the lower web 6, there is provided a horizontal guide-rail 14, which enables the lower web to clear the upper web and the drawer 10 for the same. The drawers 9 and 10 are made wide enough to leave plenty of room at the sides of thepacks ,8 and 11,'so that as the carriage travels from side to side, the

web in position on the carriage can travel with the carriage at its upper end without disarrangement. The guide-rail 14 extends far enough on each side of the drawer 10 to prevent the lower web 6 from catching on the side edges of the drawer 10.

When the device is in use, the drawers 9 and 10 are held in projecting position by struts 15 and 16, respectively. The struts engage cross-pieces 17 on the table when the drawer are in their active position. The strut 15 is longer than the strut 16, so as to cause the lower drawer 9 to project farther rearwardly than the upper :drawer 10,

thus assisting the lower web 6 in clearing the upper drawer 10. The struts 15 and 16 are pivotally mounted on the drawers 9, as by means of pins 18, to enable them to be swung to one side, permitting the drawers to be shoved into the interior of the table, so as to be out of the way. I

The utility of the device will be readily understood when taken in connection with the above description. Each of the drawers 9 and 10 is provided with a pack of web, each of which may be of its own particular character. That is to say, one drawer may contain a web of printed forms for one class of work, and the other drawer may contain a web of forms for a different class of work. When it is desired to use the lower web 6,

.mid-position, without a indicated in the drawings, it is placed on the carbon-frame 4, and the carbonsheetsinterleaved between its folds. The frame 4 is then placed on the carbon carriage 3, and, after, proper relative spacing between the carbon-sheets and the folds of the web, the collated set is fed around the platen to the printing point. The letters are written according to the forms of the web, and out off, one by one, with the proper spacing ofthe carbon-sheets relative to the web. This is more particularly explained in the above-mentioned patents.

If it is desired to write forms of the character provided for on the upper web 7, then the frame 4 is detached from, the carbon carriage, and the web doubled over in the manner shown in connection with the web,:7. This carbon-frame 4, with the web on it, can be placed out of the way, either on the surface of the table, to one side of the machine, or in the lower drawer 9 itself. Then the upper web 7, with its carbon-carrying frame 5,, may be placed on the machine.

This is done by attaching the carbon-carry- 9O ing frame 5 to the carbon carriage 3, and, after a proper relative spacing of the carbon-sheets and the folds of the web, the manifold thus formed is-fed around the platen to be typewritten on.

The number of webs may be increased, if desired, and additional drawers provided.

It will be noted that the drawers are arranged in substantial vertical register with the machine, so that they correspond to a mid-position of the carriage in its travel, enabling the webs to move at their upper ends with the carriage, to either side of this disturbing the packs of webs in the drawers. The width of the drawers also permits this sidewise motion of the webs at their upper ends.

The lower drawer 9 is held by its strut 15 and will project at the rear somewhat beyond the upper drawer 10, enabling the lower web 6 when in use to clear the upper drawer 10 more easily. To force the drawers 9 and 10 within the confines of the table, it is merely necessary to swing the struts 15 and 16 to one side. In this position, the drawers will be out of the way. When the struts are swung to one side, the drawers will slide forwardly in their guideways 12 and 13, and will be arrested when the sides of the struts strike against the crosspieces 17.

In this way, in addition to being able to write repeatedly a number of copies, of a given form, at one time, and repeat this form over and over again, a plurality of forms may be used with the same machine, and kept in a position to be readily put on or taken off of the machine without any inconvenience. Thus, the operative can change rapidly from writing form-letanother type with the same machine,-by

simply detaching the frame carrying the carbon-sheets with the web thereon. This maintains the carbon-sheets always interleaved between the folds of the web, so'that either form can be picked up at amoments notice and placed upon the machine, .ready for work.,

Variations may be resorted to within the scope of the invention, and portions of the im rovements may be used without others. aving thus described my invention, 1 claim:
