NITED STATES FRIEDRICH IVILI'IELM SABEL, OF COBLENTZ, GERMANY.
ENGRAVlNG-MACHINE.
SPECIFICATION forming part of Letters Patent No. 460,762, dated October 6, 189] Application filed March 16, 1891. Serial No. 385,313. (No model.) Patented in Germany July 16 1889, No. 51.309 in France September 5,1889,1\l0. 200,580; in England March 5.1890 andNo. 46,668.
To a-ZZ whom it may concern:
Be it known that I, FRIEDRICH \VILHELM SABEL, a citizen of the German Empire, and a resident of the city of Coblentz, Prussia, Germany, have invented certain new and useful Improvements in Engraving-llIachines; and I do hereby declare the following to be a full, clear, and exactdesoription of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.
This invention has been patented in the following countries: in Germany, No. 51,309, dated July 16, 1889; in England, No. 3,549, dated March 5, 1800; in France, No. 200,580, dated Septcmber5, 1889, and in Austria-Hungary, No. 24,085 and No. 4:6,668, dated October 7, 1890.
My invention relates to improvements in engravingmachines for copying maps or drawings or the like in a reversed position and at the same time reducing the size of the copy.
The chief object of my invention consists in the application of a pantograph as a mov, in g lever, which designs the reduced reversed drawing by means of a parallelogram frame.
In the accompanying drawings, Figure 1 represents a diagram of the devices embodying my invention, and Fig. 2 represents a top view of the said devices.
E, C, B, and D are the arms of a pantograph, having its fulcrum in A, the guidepoint in f, and the writing or drawing point in c. The latter, giving the non-reversed drawing in reduced size, is connected to a parallelogram frame, the four sides L M N O of which are equal in length. If the two opposite ends CL and b are moved in a straight line passing through both, the point i will evidently design a figure, being the reversed picture of the one described by the point 0, both pictures being of the same size. lVhen, therefore, the traveling point f is made to follow the lines of a drawing 1', the point 0 will give, according to the proportional reduction of the instrument, a right picture r of this drawing, more or less reduced in size, while an engraving-point (diamond or steel) inserted at twill engrave the reversed figure i. c., the reflected picture r -in a stone or other ,No. 3,549, and in Austria-Hungary October 7, 1890, No. 24,685
printingplate, so that the impression from it gives the right (positive) picture of the reduction.
According to my invention the points it b are guided in a straight line placed through them, not in a slide or in slots, being the easiest an d nearest, as this kind of guide leads to very serious faults, as I have found, but in a suitable link-motion guide, which I have endeavored to find out as applicable to the purpose. But all link motion guides are working only approximately in a correct straight line, and I had to'make use of a supplementary correction-guide to produce motion in an exact straight line. I have shown the well-known Lem niscoid guide as the most appropriate to the purpose.
The four rods K K and Il'll', having their fulerums on the table in p p and Z Z, are connected with their ends 6 e and d (Z to the two links J. The two points a and b will makea nearly rectilinear motion when the system is going to and fro and will approximately follow a straight line placed through a and b. I change this defective motion into a correct straight-lined one by the following device: ThetwolinksJ arenotattachedwith theirends (Z to the rods II II, but are hinged to I1 a supplementary bar, which is connected to t-hele- Vers II, in 9. These levers 1P turn on pins i, seen red on the bars II, while then-longer arms carry the two rollers 11:, intended to glide along the special curves or rules H The rods 11 serve only to carry the two rods H which glide upon one another, bymeans ofa stud and a slot, and which thus transfer the motion of the levers II upon the ends d of the links J. The two curves or rules II have been found in practice to guide the two points a and belong an accurately-dressed ruler, while two pencils placed in the axles of the rollers m traced the curve from which the correct curve has been derived by the deduction of the radius of the rollers m. It is evident that the fulcrums pl must remain in an unaltered position, respectively, to each other.
The fulcrum A is fixed upon the end of a rail A", supported by two studs A A The whole can be displaced upon an iron rod A secured to the table, and can be fastened in any position by means of a set-screw, so that the fulcrum A becomes unremovable. The bar B has one end fixed to this fulcrum and is supported by a pair of rollers B. Besides the bar is attached to this fulcrum and is provided with the carrying-roller C. The rods B and C are connected to the strong rods E and D, the latter of which carries the traveling point f. The movable rod F prevents a lateral giving way. A revolving arm G turns upon a post G and carriesa sliding block G to which the arm D is suspended by means of a pin 8. Thus the weight of the arms D and F is taken up and cannot change the traveling point. The rods BC E D F are provided with holes for adjusting the apparatus in the desiredproportion of reduction. The parallelogram frame L M N O is hooked to the point 0, giving the reduction. This parallelogram frame should not be disconnected in its corners whenever the instrument is changed for another proportion. The fulcrums p of rods K, carried by rollers K restupon parts K, which are securely attached to the table. The rods K are hinged to the links J, which carry the ends a and b of the parallelogram frame in their middle, and at their free ends the counter-guideJis hinged to the rod H which carries a pin w, projecting into a slot 00 of the lever H, having its fulcrum in Z, as also the slot may be in H and the pin on H. A lever H turning upon a stud ll on'the rod I1, is connected at g with one end to the rod H while its other end receives the roller m, which is guided along the curve of the ruler H A rod provided with a spiral spring H being supported by brackets H presses the roller m always against the curve H The latter and the fulcrum Zare disposed upon a part H securely fixed to the table.
In order to maintain the engraving-point t in its exact position, it is attached to a bar B, being slotted at y to have a pin y play therein, which projects from the rod N, hinged to M and O. A cross-rail P is provided to maintain N always in parallel position to N. The weight of the whole parallelogram frame and its connections is carried by an arm U turning on a pivot U. The free end of U is provided with a cross-bar U which is movable thereon. The arm N is hooked to one end of by means of a wire 8, while the other end carries a tin can U which is to be filled with so much small shot that the point tjust touches the stone plate S or rests upon it with exactly the pressure which is necessary for engraving. The stone S rests upon a slide S, which is moved by the two handles 5*.
Havingthus fully described my invention, I claim 1. In an engraving-machine, the combination of the pantograph B G E D with the parallelogram frame L O N M, the guide-rules I1 rollers m, and an intermediate series of levers connecting said parallelogram and rollers, substantially as and for the purpose set forth.
