COPYING-PRESS.

SPECIFICATION forming part of Letters Patent No. 602,414, dated April 12, 1898.

Appiimion tied June 21,1897. Serial No- 641.704- Nomode1.)

To all whom t rnrty concern:

Be it known that I, JOHN M. MOORE, a citizen of the United States of America, and a resident of Atlanta, in the county of Fulton and State of Georgia, have made a certain new and useful Improvement in Letter-Copying Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyingdrawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to devices for copying letters on tissue-paper; and it consistsjof the device and, further, in its details of construction hereinafter specified.

In the accompanying drawings, Figure lis an interior side elevation of the device, one side of the casing being removed. Fig. 2 is a plan thereof with a portion of the casing removed. Fig. 3 is a sectional detail of the means for pivoting the levers forming the side of the table and the frame proper of the operative parts. Fig. 4 is a sectional detail on the line 4 4, Fig. 1. Fig. 5 is a'section of the spring-barrel on the line 5 5, Fig. 4. Fig. 6 is a detail in side elevation of the frame, showing the spring-pressed roller, a portion of the main roller, and of the blanket. Fig. 7 is a detail of the main roller, showing the attachment of the blanket to the said roller; and Fig. 8 is an end view of said roller, showing the pin and eyelet forming the means of said attachment.

In the iigures like reference characters are uniformly employed in the designation of corresponding elements of construction in all the views.

A is the casing, which is composed of sides a, a bottom ct', and an end piece CL2. The sides c are extended upwardly and are rounded at one end, forming a hood by means of the cover CL3, which may be made removable, if desired, and, as shown in the accompanying drawings, hinged to a short section a4 at a5.

'The short section c4 does not extend to the bottom a', but there is below the lower edge of same a rectangular opening into which passes, after the manner of a drawer, a water-reservoir CLG, said water-reservoir lying upon the bottom a' directly under the main roller B.

c are side pieces, of metal, formed substantially as shown in Fig. l and pivoted to the casing upon downwardly-projectingarms c,as shown in Fig. 3. Between the inner ends of these arms is journaled the main roller B in a manner hereinafter specified, and superincumbent upon and secured to the other ends of these arms is a table c2, provided with hooks c3 and c4, arranged in pairs upon its top, as best shown in Figs. l and 2. Pivoted in slot- 'ted holes d in these arms is a roller D, the

periphery of which has placed thereon a tube d', of blotting-paper or other absorbent material, and bears against the periphery of the main roller B, a spring cl2 serving to hold the same in forcible contact.

If desired, a lip al may project from the back edge of the reservoir c6 at a point directly under said roller B, so as to catch any water which may drop therefrom and convey it back to the reservoir, the utility of which may be seen after the description of the operation of the device. The upward projections @8 of the side pieces c1. are slotted, as shown by broken lines in Fig. l, and the arms c have lateral projections on their inner ends, as shown in Figs. 2 and 4, which pass through these slots and, being provided with lips c6, form guides for the arms. These projections c5 are axially perforated, and the journalbearings b of the roller B are journaled therein, so that said roller will revolve freely therein.

E is a casing or barrel which is secured, as shown in Fig. 4, to one end of one of the lateral projections c5. Into this barrel e projects one end of the shaft b, and secured thereto is a coil-spring e6, its free end being secured to a pin c in the side of the ratchet-Wheel e2, which ratchet-wheel is mounted on a pivot c3, the other end of which pivot is provided with a thumb-nut, by which said ratchet-Wheel may be rotated in winding the spring, the pawl e5 serving to prevent a backward rotation of said ratchet-wheel. Now it is obvious that this spring e will act to rotate the roller B with its periphery in contact with the roller D.

F is a cloth blanket which is secured by one end to the peripheral surface of the roller B and is provided at its free end with a transversely-extending rod f. This blanket F is preferably secured to the roller B lby means of eyelets f2 and pins f', which latter are set and inclined backwardly in the roller. This blanket passes from contact with the roller B over the roller D, which, as aforesaid, is coated with an absorptive material, whereby an absorbent is interposed between the blanket and said roller, said blanket lying upon the upper side of the table c2, the rod f being engaged, when desired, with either pair of hooks c3 or c4.

The operation of this device is as follows: With the rod f engaged with the pair of hooks c3 the outer ends of the arms c are elevated, which depresses the roller B, so that its peripheral surface dips below the surface of the water in the reservoir a6. The rod is then pulled upon, so as to unroll the blanket F from the roller B, thus passing it through the water and passing it between the peripheral surfaces of the rollers B and D, whereby it is wet and the excessive water squeezed therefrom, respectively. As soon as the said blanket is withdrawn a sufficient distance the rod f is engaged with the pair of hooks cLL and that end of the arms depressed, raising the roller D out of the water in the reservoir a6 and stretching the said blanket along the upper side of the table c2.

upon the said tissue-paper. The rod f is then disengaged from the hooks c4, and, the roller B being rotated by the action of the spring e5, l

said blanket, with the superincumbent sheets of paper, (letter and tissue,) is passed between the rollers B and D and the impression of theletter taken upon the dampened sheet of tissue-paper, the whole being compressed by being wound-upon the roller B under a strong winding action, where it may be allowed to remain so long as experience shows it is necessary for the transfer to take place. The rod fis engaged with the hooks c3 and the tension of the spring e6 is suflcient to create the desired amount of pressure due to winding. During this transfer the roller B is elevated out of the water. If necessary, by reason of the ink with which the document to be copied is written being of the oil-base variety, the blanket may even be again moistened without disarranging the sheets of paper from their exactly proper relative position. the transfer has taken place the blanket is withdrawn to the position shown in Fig. l and the document and copy removed from the device, when the machine is ready for another operation.

taken is only limited by the number of the blankets or the length thereof. -Any water squeezed from the blanket between the rollers The sheet of tissue- 1 paper which is to receive the copy is then laid iiat upon the upper side of the blanket and the document to be copied laid face downwardly As soon as l.

The number of copies to be B and D will run along the lip a7 to the reservoir d6.

Then it is desired to gain access to the interior of the device, the hood d3 may be raised.

If desired, a roll-paper holder G may be secured to the casing, as shown by broken lines in rudimentary form in Fig. l, and the cutter g may be employed, whereby the sheets of tissue-paper may be severed from the roll.

Many of the elements of this device may be varied without a departure from the spirit of the invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. In a letter-copying machine, a water-reservoir, a roller depressibly mounted thereover, a motor acting to rotate said roller, and a blanket secured to and adapted to be wound upon said roller and to be extended therefrom for copying purposes, for the purpose specified.

2. In a letter-copying machine, a water-reservoir, a roller depressibly mounted thereover, means for rotating said roller, a blanket secured to said roller and adapted to be wound thereon and to be extended for copying purposes and a roller mounted elastically and adapted to press said blanket against the periphery of said first-named roller, for the purpose specified.

3. In a letter-copying machine, a water-reservoir, a roller depressibly mounted thereover, means for rotating said roller, a blanket secu red to said roller and adapted to be wound thereon and to be extended for copying purposes and a roller mounted elastically and adapted to press said blanket against the periphery of said iirst-named roller, and an absorptive covering for said pressure-roller, for the purpose specified.

4. In a letter-copying machine, a casing, a water-reservoir therein, a roller depressibly mounted therein over said water-reservoir, a motor adapted to rotate said roller, a blanket adapted to wind upon said roller, a rod in the free end of said blanket, and hooks secured to the frame at the limit of movement of the end thereof in winding upon and unwinding from the said roller, for the purpose specified.

5. In a letter-copying machine, a casing, a pair of levers mounted thereon, a table Asecured to and between same, a roller journaled on their opposite ends, a motor mounted on one of said levers and operatively connected to said roller, a blanket adapted to be wound upon said roller and drawn therefrom onto said table, and a water-reservoir below said roller, for the purpose specified.

In testimony whereof I hereunto affix my signature in presence of two witnesses.
