LETTER-COPYING IVICHINE.

SPECIFICATION forming part of Letters Patent No. 768,297, dated August 23, 1904.

Applicaticn filed J'uly 31, 1903.

T0 a/ZZ whom t may concern:

of New York, county of New York, and State of New York, have invented a new and useful Improvement in Letter-Copying Machines, of which the following is a specification.

rThe purposes and Yobjects of my invention are to provide a machine or a device by means of which pen, pencil, or type-written matter may be copied onto any ordinary copying-paper. This copying-paper may be contained in book, roll, or other convenient form. By the use of my invention letters or other written or printed matter may be copied upon such copying-paper by a much simpler and easier method than now known and without the use of a letter-press and without the use of the inconvenient and objectionable water-dish and brush. It provides an extremely simple and practical method for readily copying letters with greaty ease, certainty, convenience, and cleanliness.

I attain the purposes and objects of my invention by the mechanism illustrated in the accompanying drawings, in whichy Figure 1 is a plan view of my device. Fig. 2 is a view of my device, partly in elevation and partly in cross-section, on the Vline 2 2, Fig. l. Fig. 3 isa plan view of a slightlymodified form of my device. Fig. 4 is a crosssectional view of the same modified form on on the line 4 4, Fig. 3.

Similar letters refer to similar parts throughout the several views and gures.

My device consists of a bed-frame A, which may be the top of a table or stand or a separate piece, as shown in Fig. 2,'made of wood or any other suitable material. lTo this bed A is secured in any convenient manner, as by the screwsI s, a frame B, which has a heated lever C, iirml y secured to the frame by the ends D D/. a slightly-circular surface, in which case the two sides of the frame B preferably contain guide-slots E E', in which the ends or bearings D D-, carrying the rear end of the lever C, move up and down against the pressure of springs. Any ordinary kind of springs may be used for this purpose, as the springs The lever @preferably has Serial No. 167,689, (No model.)

F F", Fig. 2, secured to the frame B by any convenient means, as bythe pegs e and e or by a spiral form of springs G Gr', secured 1n any convenient manner, as to the frame B, as

shownat V 4in Fig. `4. The springs in whatever form areso arranged that their spring force is constantly exerted to keep the ends D D at the lowest point of the bearings, Fig. 4, or of the guide-slots E E', Fig.- 2. When the lever C is pressed down onto the copyingpaperby pressure upon the handle 7L, the ends D D are forced upward against the pressure of the springs, and as soon as the pressure is removed from the handle the force exerted by thesprings carries the ends or bearings D D back to the lowest point'of the bearings, Fig. 4, or to the lowest point of the slots E E. The frame B preferably has a stop H in the form of a rod, as shown in the drawings, for the purpose of making a stop or support lfor the lever C when it is raised in the posiwith rods 7c, of wood, metal, or other suitable material, to keep them fiat. These absorbent strips are preferably made of a material suficiently flexible that they may be rolled upon the roller L, which may be attached to the frame B in the manner shown in Figs. 2 and 4. This spring is preferably of the common automatic variety. y

In theform of my device shown in Fig. 2, a small roller r is employed to hold the absorbent strips in place. plied with a water tank or reservoir O, which may be secured in any convenient manner, as tothe frame B. as shown in Figs. 2 and 4. This'reservoir may be providedwith any convenient means for iilling, as the orifice O', Fig. l.

rIhe absorbent stripsare moistened My device is supthe absorbent strips as they are unwound from the roller L. The width of the capillary wick should preferably be approximately the same as the width of the absorbent strips, either as one wick or by the use of a number of narrow wicks. A convenient means for keeping the wick in place and in proper position is by the use of the support R, made of metal, wood, or other suitable material, as shown in Fig. 2. A iiat shield T, of metal or other suitable material, may be provided and so arranged that it may be turned by means of the knob S, so that the shield covers the end of the wick outside the reservoir. This shield when turned over the wick raises the absorbent strips and keeps them out of contact with the wick P when the device is not in use, or the wick may be provided with a toothed wheel X, as shown in Fig. 4, so that it may be raised and lowered from contact with the absorbent strips by turning the knob X, in the same way that the wick of a lamp is raised and lowered. When the reservoir is full, the water is raised by the wick more freely into contact with the absorbent strips than when the reservoir is nearly empty, so that on some accounts the toothed wheel X for raising and lowering the wick is preferable, for by keeping the wick low when the reservoir is full and raising it slightly as the water is lowered in the reservoir a uniform supply for properly wetting the absorbent strips may be maintained at all times.

In the form of my device shown in Figs. 3 and 4 (which, like the form shown in Figs. 1 and 2, may be conveniently employed to copy upon paper contained either in a book B' or a roll U) the paper roll U may be held in the manner shown in these figures and the frictionspringY may be employed to prevent the paper from unrolling too rapidly. The thin sheet of wood or metal Z, Fig. 4, may be used to keep the paper Q from coming into contact` with the dampened wick I), and the additional sheet of wood or metal Z', Fig. 4, may be used to keep the paper and the dampened cloth separated. rl`he paper Q may be made to pass more easily by using the roller n. By the use of the roller m the cloths are more readily wound and unwound. The back portion of the frame B, Fig. 2, may be provided with a case or covering c, which conceals the detail mechanism from View and protects it from dirt, accident, and injury. The lever C is provided (preferably just within its lower surface, Figs. 2 and 4) with an electrical resistance-coil a, which may be connected with an electric current in any convenient manner, as by an insulated-wire conductor as shown in Figs. 2 and 4. One end of this insulated conductor is connected with the resistancecoil within the lever C, and the other end is supplied with a plug' which may be inserted in any electric-light socket. The lever C has a smooth or approximately smooth face or lower surface f, preferably slightly circular in form, as shown in Figs. Q and 4, and made of metal, glass, or other suitable material to stand a high temperature. The resistancecoil should be of such size that the face of the lever C may be heated to a temperature of from 35()O to 500D Fahrenheit. A lower temperature than 350C gives fairly good results, while a temperature of more than 50dj is apt to scorch the paper. The requisite temperature may be readily obtained with any good resistance-coil from any ordinary electriclight socket. rlhe lcver l is provided with a handle le., of wood or other non-heat-comlucting material, for raising, lowering it, and for pressing'it down upon the copying-palm', under which has been placed the subject-matter to be copied.

rl`he mode of operation of my device is simple. The reservoir is iilled with yater, the electric current turned into the electric resistance-coil in the lever C, the matter to be copied placed under the copying-paimr in roll or book form on the frame or platform A, the dampened absorbent strip laid across the copying-paper in the manner shown in Figs. 2 and 4, the lever lowered by the operator from the raised position shown by the dotted line in Fig. 2, and the handle end la, pushed or pressed down until the lower surfacef'of the lever is brought into contact with all the surface. oi" the copying-paper under which the matter to be copied has been placed. The absorbent strips moisten or dampen the copying-pa per against which they are laid or pressed, the copying-paper in turn dampens the ink, the lever C presses the dampened copyirig-paper and the dampened ink into close contact, the heat of the lever draws the ink into the dampened copying-paper and at the same time partially or entirely dries the paper. The action of the heated surface under the slight pressure exerted on the handle /ly necessary as against the pressure of the springs l F to bring the surface f' of the lever C into contact with the dampened copying-paper under which the subject-matter to be copied has been placed will be suiiicient to make an excellent copy.

Having thus described my invention, what I do claim as new, and desire to secure by Letters Patent, is
