TYPE-WRITER.

SPECIFICATION formingpart of Letters Patent No. 659,980, dated October 16, 1960. Application filed October 31,1899- Serial No. 735,365. (No model.)

To all whom. it may concern.-

Be it known that we, ROBERT J. MINER, of Greenwich, in the county of Fairfield and State of Connecticut, and l/VILLIS E. MINER, of Roselle, in the county of Union and State of New Jersey, citizens of the United States, have invented a new and Improved Type- Writer, of which the following is a full, clear, and exact description.

This invention relates to improvements in type-writers; and a main object is to provide a type-writer for perforation or stencil-forming type, so that by the ordinary manipulation of the keys a stencil-sheet maybe formed, from which any desired number of copies may be taken by passing an inked roller over the same, forcing the ink through the perforations onto the paper beneath, thus making the machine particularly useful in railway offices where a large number of way-bills or the like are required.

A further object is to so construct the machine that either the stencil-type or the ordinary type for printing may be operated bya single bank of keys.

We will describe a type-writer embodying our invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a partial section and partial elevation of a portion of a typewriter embodying our invention. Fig. 2 is an elevation showing the parts in a different position from that shown in Fig. 1, and Fig. 3 is a face view of one of the stenciling-type.

Referring to the drawings, 1 2 designate the front and rear bars of the machine-frame for carrying the type-levers 3 4:. One of the type-levers is designed to carry one form of iype-for instance, an upper-case typeand the opposite lever is designed to carry another form of type-such, for instance, as a lower-case letter or a perforating or stencilforming type, such as indicated in Fig. 3. A draw-rod 5 extends downward from the type-lever 3, and a draw-rod 6 extends downward from the type-lever 4:- Opposite drawrods are connected at the bottom or lower end by means of a segment-shaped link 7, in the curved slot 8 of which a shifting link 9 is movable. This shifting link has a pin extended into the slot, and the lower end is connected to a key-lever 10.

The several links 9, arranged in a row, are passed through openings in a shifting bar 11, so that by moving said shifting bar toward the front or toward the rear of the type-writer the key-levers may be put in operative connection with either one of the sets of type as desired-that is, when the links 9 are in the position indicated in Fig. l the operation of the key-lever 10 will operate the typo-lever 3, the type-lever 4 remaining stationary; but by shifting the several links by moving the draw-bar 11 toward the rear of the machine, as indicated in Fig. 2, an operation of the keylever 10 will operate the type-lever 4.

Supported on the carriage of the machine is a flat impression-bed 12, consisting of rubber or similar material, mounted either on the under or upper side or both sides of a metal plate 13., By making the impression-bed flat, as shown, it will permit the type or printing character to strike full and true, thus insuring a perfect letter or character, be it for either printing or for perforating. At one side of the impression-bed and supported in the carriage 14 are paper- feed rollers 15 and 16, and feed-ro1lersl7 and 18 are arranged at the opposite side of the impression-bed. The lower surfaces of these feed-rollers are, as shown in Fig. l, on a plane with the lower surface of the impression-bed, so that the paper will be caused to move smoothly over the bed.

While we have described the machine as having a set of stenciling-type and a set of ordinary printing-type, it is to be understood that instead of the stenciling-type we may employ other forms of type or charactersthat is, one set of type may consist, for instance, of upper case and the other set of type may consist of lower case. Any suitable means may be provided for locking the shifting bar 11, so that the form of letters or characters desired may be used as long as required-that is, the operator may use the stencil-letter and complete a stencil form for duplicating purposes and release or shift the bar 11 and proceed to Write in the usual manner.

The machine as complete will enable an operator to manipulate eighty-four letters or" characters with forty-two keys-that is, a double set of type with a single keyboard, the type being so arranged that each letter or character has a separate spindle, thus obviating all blurring, regardless of the number of sheets of paper used.

Having thus described our invention, we claim as new and desire to secure by Letters Patent w 1. In a type-writing machine, two sets of type-levers, draw-rods extended from the levers, connections between the opposite drawrods, key-levers, and shiftable connections between the key-levers and the draw-rod connections.

2. In a type-writing machine, two sets of type-levers, draw-rods extended downward from said type-levers, link connections between opposite draw-rods, key-levers, and links connected with said key-levers and shift able on the first-named links, substantially as specified.

3. In atype-writing-machine carriage, a flat impression-bed, and feed-rollers at the opposite sides of the impression-bed, the said bed and rollers being mounted on the carriage, substantially as specified.

4:. In a type-writing machine, type-levers pivoted on the machine-frame, draw-rods extended downward from the type-levers, segmental links connecting opposing draw-rods, key-levers, links extended from the key-1evers to shifting connection with the segmental links, and a shifting bar for simultaneously moving all of the last-named links, substantially as specified.

5. In a type=writing machine, two sets of type-levers, perforating type carried by one of said sets of levers, draw-rods extended from the levers, connections between opposite draw-rods, key-levers, and shiftable connections between the key-levers and draw-rod connections, substantially as specified.
