WALTER THEXTON, OF DULUTH, MINNESOTA.

COPYING-PRESS.

SPECIFICATION forming part of Letters Patent N 0. 638,608, dated December 5, 1899.

Application filed March 18,1899.

To all whom it may concern:

Be it known that I, ALTER THEXTON, of Duluth, in the county of St. Louis and State of Minnesota, have invented a new and Improved Copyiug-Press, of which the following is a full, clear, and exact description.

This invention relates to improvements in presses for making copies of letters or docum ents written or printed in copying-ink; and the object is to provide a simple press with which the copies may be readily and quickly made in press copy-books.

I will describe a copying-press embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of a copyingpress embodying my invention. Fig. 2 is a section on the line 2 2 of Fig. 3, and Fig. 3is a partial plan and partial section on the line 3 3 of Fig. 1.

Referring to the drawings, 1 designates the bed-plate of the press, made of any suitable material and having its top formed in the arc of a circle, and on this top is secured a pad 2, of rubber or the like. This bed-plate is mounted on a frame 2, and from this frame 2 convergent standards 3 extend downward and have their meeting lower ends seated in castings or sockets 4, having base-plates 5, through which screws or bolts may pass to secure the press to a floor.

Removably placed above the cushion 2 is a cover 6, consisting of rubber or similar suit able material, and this cover 6 is here shown as detachably connected at its rear edge to the bed-plate 1 by means of clips 7.

Attached to the rear of the frame 2 is a water-tank 8, in which is a roller 9 for receiv ing a dampening-apron 10. Attached to one end of the roller 9 is a cord 11, which extends over a roller 12, mounted on the rear wall of the tank 8, and to the free end of this cord a weight 13 is attached. This weight is designed to automatically rotate the roller 9 to wind'the apron 1O thereon when released, and the roller 9 is sufficiently low in the watertank to permit the said roller and the apron Serial no. 709,669. (No model.)

wound thereon to be wholly immersed in the water.

Journaled in the tank 8, forward of the roller 12, is a wringing-roller 14, preferably consisting of rubber or similar yielding material having a hard metal spindle. Movable over the bed-plate is a rubber roller 15, having its journal-bearings in castings 16, from which rods 17 extend downward and have pivotal connection with a foot-treadle 18, pivoted to the castings or sockets 4. The castings 16 are connected bya cross-head 19, and the shaft of the roller 15 is provided at one end with a crank 20. The roller 15 not only serves for press-copying; bu t it serves, in conjunction with the roller 14, to squeeze out the superfluous water from the apron 10that is,

by running out the apron 10 between the rollers 14 and 15 and by turning the said roller 15 by means of the crank 20 the superfluous water will be squeezed out of the apron, the necessary pressure being applied by pushing downward on the foot-treadle 18.

Forward of the bed-plate l is a swinging table 21. This swinging table is mounted on standards 22, pivoted at their lower ends to arms 23, extended from the standards 3, and the table is held yieldingly toward the bedplate by means of springs 24.

The mode of procedure in copying is as follows: First place the copy-book on the table, with one of the covers and with the leaves upon which matter has already been copied placed between the inner edge of the table and the front edge of the bed-plate 1. Now roll out the copying-apron between the rollers under light pressure. Then roll the upper roller across the press back and forth. This will dampen the upper side of the detachable cover. After this the detachable cover is to be removed and the process repeated on the cover of the bed-plate. It may be here stated that it is necessary to remove the detachable cover only once a day or after the press has face downward on the dampened leaf. Then replace the detachable cover, after which another leaf of the book is to be placed on the top of the detachable cover and dampened as before under heavy pressure. This pressure dampens the second leaf and copies the letter on the first leaf at the same time.

Particular attention is called to the fact that the leaves of the copy-book are dampened before the impression is taken and also that the second leaf is dampened at the same time the first is taking the impression.

The press is fastened to the Wall by having its arms 23 extended rearward. The object in mounting the table 21 to tilt is to drop the leaf or page after it is copiedthat is, by drawing the table forward the copied leaf is drawn off the press and drops between the table 21 and the bed-plate 1. Of course one of the covers of the book and previously-copied leaves will already have been in this position.

Having thus fully described myinvention, I claim as new and desire to secure by Letters Patent 1. A copying-press, comprising a bedplate having a curved upper side, a cushion or cover on said upper side, a water-tank rearward of the bed-plate, and an apron movable into and out of said water-tank, a roller movable over the bed-plate, a crank on the shaft of said roller, upwardly-extended rods in which the shaft of said roller is journaled, a treadle to which the lower ends of said rods are pivoted, and a tilting table yieldingly held toward the bed-plate, substantially as specified;

2. A copying-press, comprising a bed-plate,

dampening devices connected With the bedplate, a pressure-roller movable over the bedplate, a tilting table forward of the bed-plate, and means for holding said tilting table yieldingly toward the bed-plate, substantially as specified.

3. A copying-press, comprisingabed-plate formed in the arc of a circle on its top, a cushion on said bed-plate, a removable cover over said cushion, a water-tank rearward of the bed-plate, an apron movable into and out of said tank, a pressing-roller movable over the bed-plate, and means for imparting pressure to said roller, substantially as specified.

i. A copying-press, comprising a bed-plate, a pressu re-roller movable over said bed-plate, a water-tank at the rear side of the bed-plate, an apron movable into and out of said tank, a tilting table forward of the bed-plate, and means for holding said tilting table yieldingly toward the bed-plate, substantially as specified.

5. A copying-press, comprising a bed-plate curved on its top, downwardly-convergent standards on which said bed-plate is supported, sockets for receiving the lower ends of said standards, a foot-treadle mounted to swing on the sockets, a roller movable over the bed-plate, rod connections between said roller and the foot-treadle, a water-tank, and a dampening-apron movable into and out of said tank, substantially as specified.
