STENCIL APPARATUS.

SPECIFICATION forming part of' Letters Patent No. 495,604, dated April 18, 1893.

Application led Juno 6, 1892. Serial No. 435,768. (No model.)

To a/ZZ whom it may concern:

Be it known that I, HENRY SORG, of Rochester, in the county of Monroe and State of New York, have invented a certain new and useful Improvement in Stencil Apparatus; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the drawings accompanying this specification.

Myimprovement relates to stenciling apparatus and consists in the construction and arrangement of parts hereinfter described and claimed.

Inv the drawing--Figure l is a plan View of the apparatus. Fig.2 is a longitudinalvertical section in line @c of Fig. l. Fig. 3 is a plan view of one end of the flexible stencil ribbon and a portion of the guide with which it connects. Fig. 4 is a cross section of the ribbon and an elevation of the inking roller.

A indicates the frame, consisting of two side bars a a and a rear cross bar b.

c is a handle by which the device is held and operated.

My improvement is as follows:

B and B are two rollers, one in front of another, mounted on xed shafts d d between the sides a a of the frame. l

ff are spiral springs resting inside the rollers and around the shafts, one end of each being attached to the roller and the other to the shaft. By this means spring action is imparted to the roller sufcientto wind up the stencil ribbon.

C C are the stencil ribbons or bands, one for each roller. Theyare attached to the rollers and wound up thereon. They are cut witha Series of letters,figures, or other desired characters, andwhen the device is in use are brought under the inking roller by simply drawing the ribbon outward against the tension of the spring roller. I do not limit my invention to any particular number of spring rollers and ribbons. Forordinary purposes a single roller and ribbon are sufficient. Where two ribbons are used one preferably has letters and the other iigures. A

D is a guide, consisting of a wire loop or stirrup fastened at one end to the frame, the other end extending forward angularly as shown, and the free ends of the ribbons running through the same.

The ends of the ribbons have rods g g, which project su liiciently beyond the sides of the guides to preventthe ribbons from being drawn back free of the guides. This is shown in Fig. 3. On the back of the guide are stops 7L h, to prevent the ribbons from slipping down out of place when not in use. On the edges of the ribbons are narrow flexible strips 7c lc, of rubber or other suitable material,which will wind with the ribbons, said strips serving as dams to prevent the ink from fiowing olf at the sides. Small pins Z Z may also be placed at the sides, opposite the characters on the ribbon, to indicate their position when drawn out for use.

E is the ink well, mounted in a suit-able position on the frame, its top having a lling cap fm, and its bottom a slot or opening through which the ink can pass. G is a transferring roller under the well, and H is the in king roller for applying inkto the ribbon. The two rollers are always in contact, and are geared together by spur gears n n at `one end. The bottorn of the ink well is protected by a felt or other packing o, which prevents leakage.. The felt may be dispensed with.

In use the apparatus is placed over the surface to be marked and the ribbon is drawn out till the desired letter rests under the inking roller. The latter is then rolled overit till the print is made. The apparatus is then shifted sidewise to the position for the second letter, the ribbon is drawn out to bring the second letter under the inking roller, and this process is repeated till the desired word is printed. When the ribbon is released the spring roller draws it back to place. The ribbon is preferably made of thin and flexible sheet metal, but may be made of any other suitable material. The inking roller also has preferably a composition similar to that used on printers rollers, but any suitable substitute may be used. A

Having described my invention, I do not claim a set of rollers with an endless stencil band passing between them.

What I claim as new, and desire to secure by Letters Patent, is

l. In a stencil apparatus, the combination, with the frame A, of the inking apparatus consisting of the iuking roller H, transferring roller G and well E, mountedon the rear of the frame, the spring roller B, mounted on the front of the frame, and the stencil ribbon C attached to the roller and winding thereon by its spring action, as shown and described and for the purpose specified.

2. In a stencil apparatus, the combination, with the inking apparatus consisting of the ink roller H, transferring roller G and Well E, and With the stencil apparatus consisting of the spring roilerB and ribbon C, of the guide lo D, consisting of a loop, arranged angularly between said parts and provided with a stop 7L for holding the free end of the ribbon, as herein shown and described.

In witness whereof I have hereunto signed my naine in the presence of two subscribing r 5 witnesses.
