a thickness, as to engage only one of the five type 

 circles at once, and their distance from each other is 

 such, that they take the same circle in the one M 

 they do in the other. Now, by moving the back axis 

 a small quantity endwise, it is obvious that the 

 1 H can be brought to act upon any of the five 

 elides, or be placed in such a position as to be clear 

 of them all. It is for this purpose that the head I, 

 Fig. -, cornea through the frame of the machine ; 

 for by means of this the axis can be moved on end, 

 aud by proper marks upon it, it may be set to any of 

 the five circles. In these positions it is confined by 

 a semicircular clip, which enters grooves turned 

 round on the axi.-s and deprives it of longitudinal mo- 

 tion, unless when the clip is raised. This can be done 

 by a nut coming through the back of the frame at 

 K, F>!r- I. It has a short lever on the inside of it, 

 which, when the nut is turned round, raises up the 

 clip, and releases the axis while it is set to the re- 

 quired circle, and the clip being let fall into the pro- 

 per groove, confines it from any farther motion. In 

 order that all the circles may stop at the exact point, 

 when the figure is at the highest, and consequently 

 when the surface of the figure will be horizontal, an 

 r notch is made on the inside of the figure 

 , in the intermediate spaces between each fi- 

 gure; and at the lowest point of the circle e, Fig. 1, 

 a moveable piu is titled into the Used axis, with a 

 spring, which gives it a constant pressure dovvn- 

 The end of the pin is formed spherical, and 

 well polished, so that when the circle is turned round, 

 it is forced into its hole in the axis ; but when ano- 

 ther notch in the circle presents itself, the pin presses 

 out into it, and retains the circle with a moderate 

 lorce in its proper position, until the raising of the 

 tympan, as before described, overcomes the resistance 

 of the pin, and turns the circle round. By this con- 

 trivance, the types always arrange themselves into a 

 straight line, atter being turned round, without 

 which the impression would have a very disagreeable 

 and irregular appearance. The tympan E, Fig. 1, 

 is composed of two parts: a solid brass plate, against 

 which a few folds of cloth are placed and secured by 

 the second part, which is a brass frame, covered with 

 parchment, and attached to the former by four 

 screws, two of which appear at ff'm Fig. 2. The 

 brass plate of the tympan is fastened to the leaf L, 

 Fig. 1, projecting from the axis, by means of six 

 screws. Two of these, only one of which, h, can 

 be seen in the figure, tend to throw the tympan from 

 the leaf, while the other four, which are arranged 

 one on each side of the two former, draw the tym- 

 panum and leaf together. By means of these screws 

 thus acting in opposition, the tympan can be adjust- 

 ed so as to fall exactly parallel upon the type, and 

 communicate an equal pressure to all parts of the 

 paper, which is held against the tympan, by means 

 of a frisket of parchment, stretched on a frame which 

 surrounds the tynipan, and is moveable on joints at 

 /.', k. Fig. 2. The frisket is cut through, as repre- 

 sented by the shaded parts in Fig. 2, in order to ex- 

 pose the paper where it is to receive the impression 

 of the figures, and the N before the figures, and 

 also the impression of the date, year, and place. 

 The type for these are formed in stereotype, and 

 listened down upon the surface of the brass cover a, 



the piece containing the day and moi.tli being cUaa- 

 ged every day. In order to find the proper position ^i 

 which the paper should occupy upon the tympan, ^ 

 two lire pins are fixed to project from it, and are re- 

 ceived into holes made in the brass cover: Two 

 il .t-i are printed upon the note from the copper 

 and tile pins being put through at these dots, 

 . the figures, &c. coming on their proper 



The manner of using the machine" is as follows : 

 Suppose the back axis put so far on end as to be de- 

 tached from all the circles ; the figure circles ar- 

 ranged by hand, so that the blanks are all upper- 

 most ; and the proper stereotypes put in for the date. 

 The back axis is then first set, so that its wheels H 

 may take the first of the five circles towards the 

 right hand, and, by moving the handle down almost 

 to touch the type, and returning it up again, the 

 pallet moves the wheels H, and turns the two right 

 hand circles, bringing up figure 1. The clerk now 

 inks the type with a printer's ball, opens the frisket 

 sheet L, Fig. 2, on its hinges, and places the note, 

 (already printed in the copper-plate press), against 

 the tympan, the proper place being determined by 

 the two pins and the dots printed on the note, as be- 

 fore mentioned. He now shuts up the frisket sheet, 

 in order to confine the paper and to keep it clean, 

 except in the places where it is to be printed ; then, 

 by pressing down the handle F, the impression is 

 given ; and on lifting it up again, it moves the circles 

 and brings up figure 2. The note is now removed, 

 a fresh one put in, and so on, the figure always 

 changing every time. During this operation, the 

 two right hand circles act as units, and advance 

 one each time. When 9 are printed in this manner, 

 and comes up, the handle is moved twice succes- 

 sively without printing, which brings up a blank and 

 then 1. The back axis is moved, to act upon the 

 second circle from the right hand, which now be- 

 comes the units, the first circles representing tens ; 

 by moving the handle a, without printing, figure 1 

 in the second circle comes up, making 1 1, the next 

 time 12, and so on to l<j. The first circle is now 

 put forwards by hand, bringing up 2 and 0, on the 

 second 20, then moving the handle to pass the blank, 

 produces 21, 22, <!v.c. to 30, when the first circle is 

 again advanced, bringing up 4 ; in this manner the bu- 

 siness proceeds to 99. The back axis is now shifted 

 to the third circle, which becomes units, the s 

 tens, and the first hundreds ; the and blanks of 

 which are advanced to bring up 1, is brought up in 

 the second ; and the machine itself brings up in the 

 third ; after printing this, it changes to 101. The 

 process now continues through the successive hun- 

 dreds in the same manner as before, till 999. The 

 back axis is now shifted to the fourth circle, and the 

 three first must be advanced by hand when they re- 

 quire it. At 9999 the back axis is shifted to the fifth 

 circle, and will serve to 999,999, beyond which it is 

 not required to print.
