Letters Patent No. 84,904, dated December 15,- 1868.

The Schedule referred to in these Letters Patent and making pan: of the saine.

To all whom it may concern I Be it known that we, O. H. REED and A sA L. GAR- RIER, both of Washington, in the county of Washington, and in the District of Columbia, have invented a certain new and useful Machine for Washing Printers Inking-Rollers and 'we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and

l to the letters of reference marked' thereon, in which- Figure l is a longitudinal section of our invention;

Figure 2 is a plan view of the same; Figure 3 is anend elevation; and Figure 4 is a transverse section through the .centr of one of the boxes containing the brushes.

The nature of our invention consists in constructing a machine, which shall, by means of revolving brushes, scrubbing the surface Aof printers inking-rollers with lye and water, clean them, and then, by causing them.

which we let a box containing two compartments, (B`

and 0,) securely fastened to the stand A.

B is the compartment, into'which the lye or-othei suitable liquid is poured, until its upper surface is just below the opening in the wipers W.

The bottom of this compartment is'made to slope to its centre, and that is several inches lower than the bottom of compartment Gi w The centre ofthe bottom has an orifice through a nozzle, with a thread cut on its outer side, by means of which the mouth of the dirt-box O is screwed to it, and 'box O is secured in its place.

Dirt-box O is intended to receive all the dirt that is taken from the ink-rollers in passing .through compartment B, so that the dirt can be readily removed when. it accumulates.

While the box O is fulfilling its oiiiceby collecting the dirt, the rod o, with its valve fu, is held up in the position shown in iig. 1,. But when the box O is being removed, to empty the dirt, the spring 'v' presses against the valve c, and thus causes the rod o to slide down through the hole inuits guide-bar V until the valve c rests upon the bottom of compartment, and closes the orifice. The dirt-box O can then be emptied without any waste of the lye.

Water is poured in compartment O, of the same height as the lye is in compartment B. Its bottom is flat, and has a cock fitted in it, bym-cans of which the u water, when it becomes dirty, is drawn off.

In each of compartments B and C there is a box, D, not so wide, long, or high as either of them.

Each box, D, has a close cover an open lower side; two of its opposite sides made close, d and d, and secured thereby to the compartmentsY in a secure man; ner, as seen in fig. 4; and the two remaining sides of each box D, (marked Z,) have circular' openings in their centres, which serve as bearings for hubs e and e of the reel E. l v

Each reel Eis constructed with twohubs, e and e, from which the encircling disks c expand. -These disks, c, are united together by bolts or braces a, which are constructed so as to assist in dashing the lye or vwater copiously among the brushes. u

On the inside of each disk c there are secured three guides, f, as shown in iig, -4, which project out from the disks cinto corresponding' recesses in the opposite ends of all the brushes G.

The brushes are made of stiif bristles, or other suitable material, and the-hair-side voff each brush is made:y

concave, lso as to tit the convexity of the ink-roller.

The brushes are held by au elastic band, g, or :other suitable means, tightly against the ink-roller While the reel E is being revolved.

The compartments B and C have what we term a wiper, W, in their outer ends, and one in the partition between them.

The wipers are disks of rubber, secured to their respective positions on the compartments, over circular holes therein, which holes are of sufficient size to admitofthe easy passage of the-largest-sized ink-roller.

In the centre of eachvdper is an opening for the passage of the roller to be cleaned.

M is a-frame-work for supporting the rollers L, upon which the inking-rollers are carried.

R R are two pairs of feed-rollers, made of rubber, o r ther yielding substance',to act "upon and feed in and: out the inking-rollers. They are driven by belts p from shaft S. 4

Having fully described our invention,

Whatv we claim as new in a machine for Washing inking-rollers, is- ,Y

l. The double box B C, for containing a cleansingsolvent and clear water, in combination with the brushes G, constructed and operating substantially as and for the purposes set forth.

2. 'lwo or more brushes G, constructed and operating substantially as Aand for the purposes set forth.

3. The boxes D D, constructed and operating -in combination with boxes B O, substantially as and for the purposes set forth.

4. The dirt-box O, provided with rod o, valve V, and spring o', constructed and operating substantially. as described.

5. rlfhe reels .E, provided with disks c, substantially as and for the purposes set forth.

6. The elastic wipers W', constructed and operating substantially as and for the purposes set forth.
