PANTOGRAP-H ENGRAVlNG-MACHINE.
SPECIFICATION forming part of Letters Patent No. 302,567, dated July 29, 3.88%l
Application led April 22, 1884. (No model.) Patented in Germany August 10, 1883, No. 26,291.
To all whom it may concern:
Be it known that I, ALBERT KELLE1-DO- RIAN, engraver, residing in Mlhausen, Alsace,-German Empire, have invented new and useful Improvements in Pantograph Engraving-Machines, (for which I have obtained apatent in Germany, August 19, 1883, No. 26,291,) of which the following is a specification.
My invention relates to pantographs for engraving printing rollers or platesi. e., to apparatus serving to transfer a drawing, in reduced size, to a metal roller or plate to be used in printing on cloth or other material. More especially, it has'reference to such apparatus of this kind in .which carriages traveling at a right angle to each other are used 5 and the improvements consist in the means employed for conveying motion, reduced in a certain ratio, from one pair of carriages to the other, and
for reversing the direction of motion of the en-V graving-point.
The invention is represented on the annexed iive sheets of drawings.
Figure l is a plan showing the main features of the invention, the levers H and L being placed at an angle to the carriages. Fig. 2 is a front view of a colnplete apparatus carried out according to the invention. -Fig. '3 is a side view thereof, and Fig. 4 a plan.v Figs. 4t and 4b are detail views of the device for reversing the motion of the engraving-point. Fig.` 5 is a sectionalview of a part of the apparatus drawn to a larger scale. Fig. 6 is a sectional View showing a modified arrangement of the apparatus.
To the brackets B of the frame A of the apparatus is fixed a table, C, on which the drawing to be copied is placed. y
W is a roller covered with'a coat of etching- Varnish, which is to receive the engraving.
g is the tracingpencil, and n, Fig. 1, the engraving-point. Of the latter there may be two, as shown by Figs. 2 and 4, or even more. The arrangement of the apparatus is such that all movements of the pencil g from the right to the left, or vice versa, which I shall -call the transverse movements, are transferred in the same or in opposite direction to the point or points n, while the movements toward and away from the operator, or the longitudinal movements, cause a rotation of the roller W, which is carried by centers It. The pencil g is fixed to a slotted guide-bar, G, constituting a part of a carriage, F, mounted on wheels or rollers F', running in or upon ways on the carriage E, the said ways being formed by rabbets or grooves, or in other suitable manner. The carriage E in its turn runs on wheels or rollers E' in or -upon stationary Ways D, Figs. 2 and 8, arranged at a right angle to the Ways of the carriage F. lIn the slotted guide-bar G is amovable slideblock, pivoted at l to a lever, L, having its fulcrum at Z2, and engaging at Z', by means of a pivot, with aslide-block working in the slotted bar k. This bar forms part of a carriage, K, connected by its arm k (see also Fig. LF) to the arm m of a carriage, M, having adj ustably secured to it one or more saddles, N, each of which carries an arm with an engraving-point, n. Both carriages, K and M, which, when connected together as de scribed, may be considered as a single carriage, run by means of their respective wheels or rollers K and M in or upon stationary ways parallel to the ways of the carriage F. The carriage E is provided with a slotted bar, e, in which slides a block, pivoted at h to the le` ver H, turning on its fulcrum h2, and engaging at h by a pivot with a slide-block movable in the slotted bar i. This bar is fixed to a carriage, J, running upon the wheels or rollers J, which are guided by stationary ways arranged above the carriage E and parallel to the ways of this carriage. On tlie carriage J there is a saddle, P, adapted .to be slid lengthwise on the same, and to be secured thereto in the required position. To the said saddle are attached the ends of a band of metal, Q, which is slung with its middle part around one end of the roller W, and which is stretched sufficiently tight to act on the roller by means of friction. Vhen the pencil g is moved, the transverse component of its motion will be transferred by the carriage F and the lever L to the carriages K and M and the engraving point or points a, the motion of n bearing to the transverse motion of gthe proportion of the length of the lever-arm ZZ Z to that of the entire lever extending from Z` Z.
IOO
The longitudinal component of the motion of g is transferred by the carriage E and the lever H to the carriage J and the metal band Q., which latter consequently imparts to the roller W a rotative motion, the extent whereof, measured on the surface of the roller, is in proportion to the longitudinal motion of g as the length of the lever-arin h2 h is to the whole length of the lever extending from 71.2 7L. The pivots at h and Z', by which the levers H and L engage with the slide-blocks in the slotted bars i and k, respectively, are arranged to be shifted on the said levers in the manner shown in Figs. 2 and 6. The lengths of the leverarms h2 h and Z2 Z may thus be varied, and the proportion in which the design is reduced in size altered accordingly.
The band Q, is conducted over sheaves p2 and fixed with its ends to a slide,p, Fig. 5, guided between ways on the saddle P, and adjustable by a screw, p. This arrangement allows the roller to be turned by the requisite angle when a strip thereof has been iinished and the design is to be repeated. For the purpose of accurately determining the said angle, a divided disk, S, Figs. 2 and 4, is placed loose on one of the centers R, and connected wit-h the roller, while an indicatoris iixed to the same center. The screw p3 serves to stretch the band Q to the necessary degree. The centers B are carried by puppets arranged to be slid on and iixed to an axle, r, Figs. 2to 5, which is mounted in xed bearings, and adapted to be turned by a screw, r', gearing with a sector on the said axle. By means of this mechanism the centers may be raised and lowered simultaneously and uniformly, and the roller thereby adj usted at the proper height relatively to the band Q.
Vhen the two carriages K and M are rigidly connected together, as shown in Figs. l and 4, they will both move in conformity with each other and in the same direction as the carriage F. rFhey may, however, also be brought in such relation to each other as to move in opposite directions by means of the metal band o, Fig. 4. This band runs over guiding-sheaves O, and is attached at either end to an arm, m2, on the carriage M, while in the middle it may be xed to the arm k2 of the carriage K. In order to allow either connection between K and M to be established and broken with facility, the arm 7c', with which the carriage K is provided, is pivoted thereto, so that it may be turned over from the position of Figs. 4 and 4L into the position shown by Fig. 413, and its end 7c3 iits between the two branches of the forked arm m on the carriage M. By means of regulating-screws ma the clear space between thel said branches of the arm m may be adj usted to be in conformity with the thickness of the part 75s, and this part may be made slightly tapering for attaining perfect contact with both screws m3. Moreover, for connecting the carriage K to the band o, the arm k2 is provided with a clamping device consisting of the jaw-piece or` washer 7a4 and screw with nut k, by which the band o may be clamped against the end of the arm k2. When the arm 7c is out of engagement with the arm m, and the two carriages are connected by the band o, the carriage M will move in a direction contrary to that of the carriages K and F, and the design on the roller will be produced in inverted position, as com* pared with the pattern. It will be seen herefrom that the carriage M is of importance only for this special purpose, whereas when the design is not to be inverted it may be left away, the engraving-point having then to be attached to the carriage K.
Fig. 6 shows a modified arrangement with two carriages M placed below the'carriagelJ, and each having one or more holders with engraving-points n acting on either side of the roller WV. Besides, in this gure, the roller WV is supposed to be rotated by a friction-bar attached to the carriage J, and acting with a roughened surface on a disk, T, secured to the roller, or keyed on an axle, w, on 'which the roller is placed. This arrangement is preferred for large rollers. The axle w may be mounted in bearings adjustable between the upright brackets a. When a plate is to be engraved, the carriage J is provided with a table, to which the plate may be secured,while the parts serving to carry and rotate a roller are put out of operation. All the rest of the mechanism remains the same as before. The arms carrying the engraving points n are formed by levers pivoted to the saddles N, (see Fig. 5,) and so balanced that the points will act by gravity against the roller W". Vhen the points require to be lifted off the roller, the tail ends of the levers are depressed by a rod, u, Figs. 2, 3, 4, and 5, carried by the lever-arms U on the kshaft fr, which is connected by the arm U', the lever U2, and suitable rods to the lever U3 of a pedal, u, the parts being so arranged that when the pedal is pressed down the bar u will be raised, so as to allow the points n to bear on the roller, whereas on releasing the pedal the bar u will be depressed by a weight fixed on the lever U3, and the points n thereby raised.
For carrying out the shading 4of the drawing it is of advantage to havefa second tracing-pencil, g', attached by an arm, G', t0 the bar G. Under this pencil plates are placed, in which are engraved the hatching-lines to be reproduced to a smaller scale, and while the operator follows these lines with the pencil g he determinestheir length bythe motion of the pencil g on the pattern.
