Definitions

  • My present invention relates to an engraving and reproducing apparatus for sculptural work.
  • a more particular object of my .invention is to permit the reproduction of solid bodies or relief objects and the change of the original scale without the necessity of specic measurements of individual parts.
  • my present invention mainly consists in an engraving and reproducing apparatus for sculptural work, comprising in combination, a stationary support, elongated generally horizontal rst carrier means disposed on said stationary support, two work tables, one for the model object and the other for the work, means for moving the said work tables along said first carrier means, substantially vertical support means, elongated second carrier means pivoted at one end to said Vertical support means so as to be tiltable towards said rst car- Iier means, a pair of spaced elements movable on said second carrier means, a guide tool carried by one of said elements, a working tool carried by the other element, and means for simultaneously adjusting the position of Said two elements relatively to said work tables.
  • Fig. 1 is a side elevation of the apparatus according to my invention
  • Fig. 2 is a plan view showing the apparatus in working position for the reproduction of solid objects
  • Fig. 3 is a detail view of Fig. 2 illustrating particularly the guide and working tools
  • Fig. 4 is a diagrammatic view of the universal joint employed in the apparatus
  • Fig. 5 is a diagram illustrating the underlying mathematical concept
  • Fig. 6 illustrates another embodiment for use in the reproduction of relief objects, the View shown being a partial side elevation
  • Fig. 7 shows the same parts as Fig. 6 inplan view
  • Fig. 8 is a partial front elevation of the embodiment illustrated in Figs. 6 and 7.
  • the apparatus comprises two horizontal bars generally indicated as 1. These bars nited States Patent 2,739,511 Patented Mar. 27, 1956 constitute the first carrier means of the apparatus.
  • the bars are supported at their ends by stationary legs 2.
  • cooperating disc members 3 and 4 Interposed between the bars and legs are cooperating disc members 3 and 4 which permit a relative angular displacement so as to provide for an inclination of the bars about the axes of discs 3 and 4.
  • a pair of clamping nuts 4a and 4b hold the discs 3 and 4 in adjusted position.
  • Movable on the bars are two slides 5 which are provided with movable working tables 6 and 6.
  • the lengthwise movement of the slides is accomplished by handles 7 which actuate pinions 8 for cooperation with the rack portion 9 which is provided at the bottom of the bars 1.
  • a revolving mechanism consisting of extensible bars 12; worms 13 and worm wheels 14 provides for revolution of the Work tables about their axes.
  • the actuating mechanism for this purpose comprises cooperating bevel gears 15 and 16 which are driven by a shaft 17.
  • Shafts 12 being extensible, the gearing mechanism associated therewith is kept in operative position relative thereto during relative movement between slides 5.
  • the shaft carries at its outer end an actuating disc 18 and a handle 20 and is supported in a slide 19 which is movable o-n one of the bars 1.
  • a support block 21 is provided from which vertical standards 22 rise.
  • a bearing box 23 is carried by these supports so as to be vertically slidable thereon.
  • a shaft 24 extends into the bearing box 23 and is freely revolvable therein.
  • the shaft 24 carries at its free end a universal joint.
  • the joint comprises a fork 25 which is fixed to the end of the shaft 24, a cross member 26 and a second fork 27. With specie reference to Fig. 4 it will be seen that the two arms 26 and 26 of the cross member are pivoted to the fork 25 while the other two arms 26" and 26" are pivoted to the fork 27. Secured to the fork 27 are rods 28.
  • These rods extend normally parallel to the bars 1 and constitute the second carrier means of the apparatus. Movable on these bars 2S are two slides 29 and 30.
  • the first of these slides carries the working tool which may be a stylus, graver, chisel or any similar implement.
  • the second tool carries a guide tool 32.
  • Pivoted adjacent the place of junction 42 between the fork 27 and the rods 28, is a lever bar 35 which at its free end is provided with a ball shaped handle 36.
  • This lever bar 35 is connected with the slides 29 and 30 'by parallel bars 33 and 34 of distinct length.
  • the bar 33 is pivoted tothe lever bar 35 at 43 and to the slide 29 at 45, the bar 34 is pivoted to the lever bar 35 at 44 and to the corresponding slide 30 at 46.
  • the bar 33 may be made adjustable as to length, or a number of bars of predetermined different lengths may be used.
  • One of the rods 28 is provided with a handle 41 which is secured thereto in any well known suitable manner.
  • a rod 4b carried by a slide 39 on one of the bars 1 extends vertically upward and provides a guide for the rods 28, by providing a rigid member against which one of the rods 28 may be brought to bear.
  • a motor 38 furnishes driving power vto the working tool 31 through flexible shaft 37.
  • the apparatus ldescribed operates as follows:
  • the model object is placed on the work table 6 and the block 11 to be shaped is put on the work table 6.
  • the lever bar 35 as a rule is swung sidewise from the position shown in Fig. l to the position shown in Fig. 2.
  • the tools are then guided by means of the handle 41 in a vertical direction (that is the direction shown by the arrow adjacent the handle 41 in Fig. 1), until the stylus 31 makes contact with the piece 11. Owing to the rapid motion imposed upon the stylus by the electric motor 3S, the tool will rapidly cut the block down toa definite point. Then the guide tool 32 will trace the contour ofthe pattern, its motion being followed by the tool 31 in the proportion determined by the triangleformed by thetbars 33, 34, 28 and 35.
  • Tool 31 andguidetnol willtrace a, semi-circular, path with the universal joint 25, 26, 27 as its center; the stylus will follow the configuration of the pattern.
  • the-.position of stylus and guide tool will bey horizontal with respect toy the operator; for following the recessesV of the ⁇ iigure,.tl1ese members may be placed at anangleor operated vertically.
  • the bars l may be placed in an inclined plane with respect to the vertical by simply loosening and tightening nuts 4a and 4bon their .screws provided to this end in the disks 3 and t so that the bars may assume the proper position.
  • Line a-d correspondsto lever bar line a-e corresponds to rods 28; line b-c corresponds to bar 33; and line d-e corresponds to bar 34.
  • lines d-#eand'b-c (bars 34 and 33) constitute the hypotenuse of two similar triangles a-d-eand cl-b--c.
  • the angular displacement of line cr-d (lever bar 35) will result in a changeof relative position of points c and e.
  • the arrangement of the stationary support and the lower or lirst carrier ⁇ means as well as the arrangement of. the working tablesxand vertical supports and standards will be the same in this ⁇ apparatus as that shown in Figs; l to 3.
  • the differences lie in the means to accompiish the necessary movements ofthe working. ⁇ and guide tool.
  • a slide member is-provided on the vertical supports 22.
  • This'slidemember has tubularguides 48 by which itcan moveon the standards22.
  • Provided in the slide member 47 are pivots 49 for a first bearing block l 50 in which superimposed intermediate carrier means,
  • bars 52 are movable lthrough tubular channels 51. Screws 53 and 54 are provided forlocking of the bars 52 in vertical and horizontal direction.
  • a second bearing block 55 is provided, which, as appears from Fig. 7, has acrescent shape so as to form projecting end pieces 56 which carry pivots 57 for an ⁇ end block 58.
  • this end block 58 the ends of superimposed barsy 59 are fixed.
  • the latter bars constitute the second carrier means of this embodiment and therefore correspond to the barsZScf the previously discussed form of the invention.
  • the slides 29 and 3.0 which cam/1 the guiding tool and working tool can be adjusted on bars 59.
  • the horizontal position in a lengthwise direction can furthermore be adjusted by sliding of the intermediate bars 52 in the bearing bloeit Stb; ln additiomthe swivel joints 49 permit rotation of the tools in a generally/'horizontal plane.
  • the vertical'inclination of the tools is accomplished by tilting of the end blockS about the'pivots 57. It will be appreciated that the horizontal dimension thusv provided 'will be ⁇ in proportion to the distancel of the tools from the pivots $9and the vertical dimension or relief depth will be in accordance with thetips' of the tools from the pivots 57:. j
  • a particular advantage of this form is the possibility cf an adjustment to such degree that the tip of theworkingV tool 31' virtually coincides withy the axis formed by the pivots 5'7. Thus disproportion between reduction in horizontal direction and reduction in relief can be diminished.
  • the working tables 6 and 6 in thisl ernbodiment should be-machine driven which can be accomplishedl by anV additional connection between the revolving shaft 17 and the motor 38.
