STENOGRAPHIC MACHINE.

SPECIFICATION forming part of Letters Patent No. 352,799, dated November 16,1886.

Application filed March 1' 1885.

To all whom it may concern:

Be it'known that I, MILEs M. BARTHOLO- MEW, of Belleville, in the county of St. Clair and State of Illinois, have invented a certain new and useful Improvement in Stenographic Machines, ofwhich the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

Figure 1 is a top view of the machine. Fig. 2 is a transverse vertical section at 2 2, Fig. 1. Fig. 3 is a rear elevation of the machine with part of the case broken away. Figs. 4 and 5 are detail transverse sections, showing the different positions of the stop-lever.

A is the base of the machine.

B is a case or frame in which the drive mechanism has bearing. This mechanism has a barrel, 0, containing a coiled spring, by which the barrel isturned, the spring having one end attached to the barrel and the other end attached to the winding-shaft D, in the usual manner. The shaft D has fixed upon it a ratchet-wheel,E, which is prevented from backward rotation by a pawl, F, pivoted to the case B, andheld in contact with the ratchet-wheel. The winding-shaft D has an angular end, D, for the engagement of the winding-key. The style of key which is shown is a ratchet'key having a handle, H, in which is j ournaled a ratchet wheel, G, having a central angular socket fitting the end D. This wheel is en gaged by a pawl, I, pivoted to the handle, the arrangement being such that the oscillation of the key will Wind up the spring in thebarrel 0. Upon the barrel 0 is a cog-wheel, J ,which is connected with the fly-shaft L by a train of gearing, K, causing the fly-shaft to revolve at a high velocity as compared with the barrel 0.

M is the fly upon the fly-shaft L. One of the shafts, as N, of the train of gearing carries the paper-feed roller 02 The paper roll is shown at P, the paper ribbon extending beneath the feed-roll O and over a supporting-roll, R, which serves to press the paper ribbon against theunder side of the feed roll. The supporting-roll has bearing on a springarm, S, secured to the standard T, upon which the paper roll is carried, the spring-arm being hinged to the staudard and having a projection, S, whose free end is connected to the base A by a spiral spring, U, and a thumb- Serial No. 159,151.

nut, U, turning on the spring-rod and bearing upon the top of the projection.

Vare the keys, carrying markers V, which on the depression of the outer ends of the keys are carried up against the ink-ribbon W, and serve to make a mark on the paper ribbon, the paper and ink ribbons passing together between the markers and an abutment-piece, X.

The ink-ribbon is coiled on two reels, Y and Y, which carry friction-disks Zand Z, and are supported on'asliding frame, a, that supports a friction-wheel, Z which is in frictional contact at its periphery with the periphery of the disk Z. By the endwise movement of the frame a either the disk Z or disk or wheel Z may be brought into frictional contact with the shaft N, or with a small friction-wheelthereon, so that either the disk Z or that Z may be turned to wind up the ink-ribbon, the other one of thesedisks being free to turn, and thus allow the ribbon to be unwound from its roller. The frame a may be moved by means of aliendie, I). c is a spring-pawl, which engages a tooth, (1, upon the top of the frame a, and prevents the accidental movement of the frame.

The reels YY have knobs by which they may be turned by hand.

It will be seen that the paper ribbon is pushed forward between the abutment piece or plate X and the marker by the feed-roll O to therear of the marker; The construction is such that the feed of the paper between the rolls 0 and B may be continuous, and yet the paper may remain at rest at the point pressed by the marker, the paper curving between the rollers and the marker. Then as soon as the paper is relieved from the pressure of the marker it returns to astraight condition. By the described construction the friction of the paper against the ink-ribbon, when they are pressed together, is avoided and the consequent blurring of the mark.

The fly M should not be rigidlyattached to its shaft, but should have frictional contact therewith, so that the arrested rotation of the fly shall not cause the sudden arrest of the fiyshaft. This arrangement is common in striking clocks.

I will now describe the device for stopping the motion of the driving mechanism.

' e is a shaft having at one end. a key, f, and i at the other end a finger, f, which by thedepression of the key is brought into the course 2. The combination, with the fly M, for the purpose set forth, of the stop device eff g, substantially as and for the purpose set forth.

3. The combination of an abutment-piece, a marker for forcing the ink-ribbon against the paper strip and the abutment, and a feed device, substantially as described, to the rear of 20 the marker, flexing the strip when detained by the pressure of the marker.
