Application March 11,

1 Claim.

This invention relates to improvements in typewriter attachments and has particular reference to a dictionary web carrier, whereby a large number of words may be readily discernible through the movement, of the Web.

A further object is to produce a device of this character which may be readily attached to the typewriter, will be convenient to use, economical to manufacture, and a device which will not b in the typists way. I

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings forminga part of this specification and in which like numerals are employed to designate like parts throughout the same;

Fig. 1 is a top plan view of my device as the same would appear when attachedto a typewriter;

Fig. 2 is a similar view on an enlarged scale, showing a portion thereof broken away;

Fig. 3 is a cross sectional view taken on an enlarged scale and. on the line 3 3 of Fig. 2;

Fig. 4 illustrates the manner in which the web is wound from one roll to the other;

of one form of driving mechanism;

Fig. 6 is-a schematic view, showing the arrangement of the index sheet;

Fig. 7 shows thedevice folded over upon the typewriter when not in use;

Fig. 8 is a fragmentary detailed view, showing the web attached to one of the rollers; and

Fig. 9 is a view similar to Fig. 5, showing a modified form of driving mechanism.

It is a well-knownfact that a person typing often has to stop and consult a dictionary, many times for simple words which are confusing; and, of course, this is a considerable loss of time to the typist. Therefore, I have provided a holder to be attached to the typewriter which will hold the dictionary sheet, upon, which sheet may be printed several thousand often misspelled words.

In the accompanying drawings wherein forthe purpose of illustration is shown a preferred embodiment of,my invention, the numeral 5 designates a casing in which are mounted shafts 6 and I. The casingi'is of an elongated form so as to extend across the full width of a typewriter frame 5. The front edge of the top 6 of the casing is curved, as indicated at 1, and provided with anopening 8' which extends approximatelythe entire length of the casing. The topof the casing in beyond the opening is provided with letters representing the entire alphabet. The

rear wall 9 at each end adjacent the upper edge.

Fig. 5 is an enlarged fragmentary detailed view 1939, Serial No. 261,253 I is provided with clips H1 and H which are adapted to clamp over the front bar of the type-' writer frame 5'. One end of a web 8 is attached to the shaft 6, and the opposite end of the web is attached to the shaft 1. This arrangement enables the web to be rolled from one shaft to. the other. with a back-and-forth movement, which will give visibility to the entire face of the web. This web is provided with a line 9 ex tending diagonally thereover, which line will travel from end to end of the device as the web is rotated. Therefore, as illustrated in Figs. 1 and 2,'the line indicatesthat the letter A is the one exposed. For instance, when the line 9 is even with the letter. H, then the H words .on the sheet'will be visible. A support is shown at I I which .underlies the web 8-, the purpose of which is obvious. p p

There are several ways in which the two shafts may be rotated. In Fig. 2 I have shown the use of an internal ring gear l2rotated by a knob it. In Fig. 5 I have shown a similar arrangement, the only difference being that the internal ring gear I2 is rotated by an intermediate gear [4. In the modified form shown in Fig. 9 the shafts 6 and l are rotated by a spur gear I6 driven by: the intermediate gear M, as shown in Fig. 5.

Thus it will be.seen that my device may be easily applied to a typewriter and will be ready for instant use.

It is to be understood that the form: of my in- .ventionherewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material,

mately itsentire length, clips carried by the rear wall thereof, a pair of rollers mounted in said casing, a web wound on said rollers-and extending across the space below the opening, a supporting plate in contact withv the web andthe rollers below the opening, gears carried by the ends of the rollers, an internal ring gear driving said gears, a knob on the outside of the casing for driving said internal ring gear, letters arranged'on the top of the casing adjacent the opening, and a line extending diagonally from one end of the tape to the other end'and adapted to register with the letters for the purpose set forth.
