EMORY FARRAR, OF NEW YORK, N. Y.

TYPE MARKING-MACHINE.

SFECIFICATION forming part of Letters Patent No. 251,425, dated December 27, 1881,

Application filed JullyliO, 1881. (Model.)

To all whomy 'it may concern:

Be it known that I, EMORY FARRAR, ot' New York,` in the county and State of New York, have discovered a certain new and useful Improvement in Type l\Iarking-l\/Iachines, of which the following is a full, clear, concise, and exact description.

My invention relates to type marking-machines or stamps, in which the type are carried upon wheels; and it consists in the combinations of parts hereinafter set forth.

Figure l is a side elevation, and Fig. 2 is a view from below, of my type-marker. Figs. 3, 4, 5, and 6 are details of portions thereof.

Like parts are indicated by similar letters of reference.

The frame D is provided with short arms pr0- jecting at right angles from its sides. The outerends ofthe arms are bored out and tapped to receive wrist-pins. The typewheels A B C turn upon these pins in parallel planes. Adjustable roller-guides E F are attached to the frame, as shown. The Wheels A and B diier only indiameter, and are shown in detail in Fig. 3, in which t is the helical spring, a side view of which is shown in Fig. 6, attached t0 the frame and to the inner disk, b, of the wheel, as shown at b'. The wheel is run over the inkpad or surface to be marked against the tension of this spring, and is brought back automatically to its normal position by its recoil.

c is the outer disk ofthe wheel, and e is the rim, which affords a support for the type. The rim e may be first placed about the disk e', and then soldered to disk b. The edges of the outer disk, c, and the inner disk, b, project inwardly, as shown at poiutsf g. The projecting edge g of disk c should be removed for a short distance, as shown at h, so that the type may be entered. The projecting edges f g fit the grooves provided in the type, which may be entered one at a time, and crowded along until the first one entered comes against the stop, which may be attached rigidlyto the rim '6. A stop, i, is shown on wheel B, Fig. 2.

After the type are entered xthe clamp k is brought against the last one entered. The clamp is held by means ofthe thumb-screw l. `The disk e moves independently, and the p0rtion h may thus be brought to any position in respect to the clamp and stop. When the thumb-screw l is tightened the disk is held firmly in position.

Wheel C is divided through the center of the rim M, as shown in Fig. 2. rlhe slot n (see Fig. l) is provided in the wheel C, instead of simply removing a portion of the projecting edge, as shown at h, Fig. 3. This slot l find the more convenient form ot opening. 'The type are entered or set one at a time in wheel C, and crowded around till arrested by a stop provided on the rim m. This stop is not shown in the drawings. It is similar to stop t', and is attached to one side only of the rim m. The type are held in place by means of the clamp o. (See Fig. 4.) The catch p (shown by dot# ted lines) is pivoted to clamp o at point q. The spring r normally holds this catch or stop p in the position shown, so that its upper end comes against the under side ot' the rim m. The clamp ois thus held in position. By pulling back on the catch or stop p against the tension of spring r, the catch or stop isv turned on the pivot and the clamp is released. The clamp is designed to hold the type in position when placed upon the Wheel.

The outer and inner disks of wheel C are held together by means ot' a thumb-screw, s.

The counterbalance-weight s', Fig. 2, may be used instead of the helical spring to bring the wheel back to position alter it has been used.

I place a spiral spring between the outer and inner disks of wheel C, around the hub. This spring tends to hold the two disks apart. By means ot' the thumb-screw the wheel may be adjusted to type of any size.

When the type are very small washers may be used.

In Fig. tail.

The leg t is pivoted to the frame, and held by spiral spring a against the stop o.

IVhile inking a wheel the supporting-wheel may be swung forward by pressing the thumb upon the, wire w.

p The wheel w is held, as shown, by sleeve y, which may be adjusted at any height upon the leg by means ofthe set-screw z.

The type I nd most desirable are of rubber fastened to a metallic base, preferably of brass.

5 adjustable guide E is shown in de- Having thus described my invention, what I Y claim as new. and desire to secure by Letters Patent, is-

1. The frame D, provided with parallel wristpins for the wheels, in combination with guides E and F, and screws for adjusting the sleeves to the legs, and springs and levers, onespring and oneleverforeach guide, whereby the guides may be held up while the wheels are passing over the ink-pad, substantially as and for the purpose specied.

2. The fra-ine D, provided With three parallel wrist-pins for the Wheels, two of said wristpins being on different sides of the widened portion of the frame, one higher than the other, so that only one of the wheels A C at the saine time may touch the surface to be marked, the other Wrist-pin being at the bent extremity of said frame, whereby the plane of wheel B is brought about midway between the planes of 2o the said wheels A and C'.

3. The combination of frame D, type-wheel C, guide-Wheel E, spring u', lever w, and stop QJ, as and for the purpose specified.

In Witness whereotl I hereby subscribe my 25 name in the presence of two subscribing witnesses.
