TYPOGRAPH.

SPECIFICATION forming part Of Letters Patent No. 555,519, dated March 3, 1896.

Application led December l0, 1894. Serial No. 531,432. (No model.)

To all whom, t may concern:

Be it known that I, HOSEA W. LIBBEY, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in T ypographs, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to certain improvements in typographs, for which a patent was issued to me the 22dY day of May, i894, No. 520,238, whereby said machine is adapted to make impressions upon a strip of Celluloid or other suitable material that has first to be heated to render the same pliable or-plastic; and the invention consists in the construction of the bed or table so that the material is heated, fed forward and impressed. The impression in the material produces a duplicate face of the type-dies, from which face printing can be donc, as hereinafter fully described, and pointed out in the claims.

Referring to the accompanying drawings, Figure l represents a side view of a typograph embodying my invention. Fig. 2 is a longitudinal vertical section of the same. Fig. 3 is a horizontal section taken on line .fr of Fig. l. Fig. 4. is a horizontal section taken on line y y of Fig. 2.

A A represent the side frames of the apparatus secured together by bolts a a and at their upper ends by cross-bars b. The upper straight portions of these side frames are formed with a groove, in which a sliding plate B is free to work on each side, said plates being retained in their normal raised position by springs 0,-the lower ends of which rest upon lugs d', formed upon the side frames, A. The sliding plates are each formed with an extension B', which at its lower end is connected to a treadle-bar D, fulcrumed on a bar or bolt d, secured to the rear legs of the side frames, A. The forwardend of this treadlebar is formed with a f oot-rest, so that when the foot of the operator is placed on the rest and forced down it carries with it the sliding plate B. A stop d' is secured upon the lower front bar, a, so that the' treadle D will always be brought to the same point when depressed.

E is a rod or bar carried by the sliding plates B, and upon this bar is a tube or sleeve E just the length to fit between said plates. A series of type wheels or disks F are mounted upon the sleeve E, said wheels having upon their periphery in duplicate letters or characters representing the entire alphabet, both capitals and small letters, as well as stops, numbers, and other signs used in printingthat is to say, one set of letters and signs are on one side of each disk and corresponding letters and signs diametrically opposite-so that when one line of reading-matter is setby the operator near the upper portion of the disks, which would be at about an angle of fortyfive degrees from the center, the corresponding letters or signs will be immediately opposite, so that by turning the disks a slight distance-say one-eighth of a diameter-from him, so as to bring the line that has been set perpendicularlyover the center of the wheel, the corresponding letters will be brought to the center of the machine, ready to be brought down to make an imprint upon the material when the treadle D is depressed.

All the parts above described are substantially the same as those described in Patent No. 520,238, issued to me the 22d of May, 1894.

' G is a bed or table having openings or slots g g g2, and the under side of the table is fitted with bearings h h', in which are mounted feed-rollers H H', that pass through the openings g g2, so that their upper surfaces are on a level with the top of the table, and in the center of the table is a roller I, covered with rubber or other suitable material and supported in bearings fi on the under side of the table. J ust at the front of this roller is a shelf or support J, upon which is placed a casing j, the upper portion of which is bent over, so as to be almost in contact with the roller I, and the top of the casing is on a level with the top of the table G. In this casing is placed a spirit or other lamp K to heat the casing J, so that the celluloid or other substance passing over it will be heated and rendered plastic just before passing under the type-wheel to receive the imprint of the -letters or signs from the type-wheels.

.The side of the casing J next to the roller I maybe covered with asbestos or other suitable material to keep the heat from the roller I.

The Celluloid or other material L is cut or formed into strips of the desired width and wound upon a roller l, supported in bearings IOO a2 on the side frames, A. yIt then passes over a guide-roller M, carried in bearings a3 on the side frames, A, and then passes over the surface of the table G, an upper feed-roller, H2, being arranged over the roller H, so that the material is gripped and carried forward upon the rotation of said roller H.

The roller H may be operated, so as to feed the material forward, in any suitable manner.

In the drawings I have shown ratchetwheels N on the ends of the shaft that carry the roller I-I and pawls P secured to each of the sliding plates B, said pawls P causing the ratchet-wheels N, and with them the feedroller H, to rotate as the sliding plates B are pressed down, thus causing that portion of the celluloid or other material that was over the lamp K to be moved over the roller I, ready to receive an imprint from the typewheels. A stop p is provided to keep the pawl from being pressed out beyond a certain distance by its spring p, so that upon the upward movement of the plates B the pawls will ride over the teeth of the ratchet-wheels ready to again operate the same.

It will be seen that the celluloid or other material, resting for a short time over the heated casingj, will become soft or pliable, and when in this state it is fed over the impression-roller I, so that when the type-wheels are brought down they will impart an impression in the impression-strips, producing a duplicate face of the type-dies, from which face printing` can be done. The roller I has a yielding surface, allowing it to be forced into the same, and wh en the type-wheels are raised the surface of the roller I will assume its norlnal position and free the impression material. Thus one line of type is formed thereon, and by repeating the operation a strip of material with raised letters, che., ready for the press is produced.

That I claim is- 1. In a typograph, the combination, with a frame, of a series of rotatable and verticallymovable type-wheels mounted therein, a bed or table below the wheels having transverse slots or openings therein, an impression-roller below the wheels, feed-rollers at the ends of the table, each of said rollers having its upper surface substantially on a level with the top of the table, and a heating device below the table in front of the impression-roller, and means for feeding the material to be operated upon from a position over the heating device to -a position under the wheels, and means for forcing the wheels upon the heated material, substantially as set forth.

2. In a typograph, the combination, with a frame, of a series of rotatable and verticallymovable type-wheels mounted therein, animpression-surface below the wheels, a heating device in front of the impression-surface, and means for simultaneously moving the material to be acted upon from above the heating device to the impression-surface, and moving the wheels toward the surface, substantially as set forth.

3. In a typograph, the combination, with a frame, of a series of rotatable and verticallymovable type-wheels mounted therein, an im pression-roller below the wheels, a casing in front of the roller, the top of which is curved toward the roller, and means for simultaneously moving the material to be acted upon and lowering the type-wheels, substantially as set forth.

4. In a typograph, the combination, with a frame, of a series of rotatable and verticallymovable type-wheels mounted therein, an impression-roller below the wheels, a heating device in front of the roller, a non-conductor of heat between the heating device and the roller, and means for simultaneously moving the material to be operated upon from the heating device to the impression-roller and lowering the type-wheels, substantially as set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 29th day of August, A. D. 1804.
