Definitions

• the invention relates to a duplicating milling- machine which operates simultaneously in the horizontal and vertical planes.
• duplication may be effected manually by looking at the original and reproducing what one sees on a blank until one obtains a piece as near identical to the original as possible. Duplication may also be effected more or less automatically when an operator guides a feeler over the contours of the original, and the movements of the feeler as it follows these contours are reproduced by a cutting tool.
• Such duplicating milling-machines are used to reproduce ornaments, sculptures, lettering or similar decorations, and reproduction may be effected on wooden, plastic or metal blanks.
• duplicators in use to-day are complex and costly machines, and only larger companies and companies mho make ornament duplication their sole business use such machines.
• Such a machine is described in "Jsrn- og Metallindustriens Handbok" (Manual for Iron and Metal Industry) No. 2, page 913, by Vilhelm Jorgensen, published by Ivar Kobenhavn 1948. This description sho ⁇ is that the machine is of complex design and operation, due to the position of the table for the original in relation to the cutting table, as this position allows no possibility for three-dimensional duplication in one single operation.
• a duplicating machine which operates in one plane only, i.e. in two dimensions.
• a feeler which can be guided over the surface to be reproduced is vertically connected to a cutting tool, but can rotate freely around its vertical axis.
• the cutting tool is connected to a driving wheel through a friction coupling.
• a three-dimensional duplicating device is described in DE-A No. 46.368.
• a feeler is fixed to a horizontal arm and the cutting tool is on a separate arm. Both arms are horizontal and interconnected by means of a bar.
• the device formed by both arms and the bar can effect slight vertical movements along a bracket.
• the device is balanced by means of a lever and weight. Horizontal displacement is made possible by the two axes around which the device rotates.
• the present invention aims at providing additional equipment for the universal hand milling machines which are now sold on the market at a reasonable price, and aims also at achieving adequate precision for reproduction of an original.
• a combined vertical-horizontal arm renders the vertical slide-bar device described in DE-A No. 46.368 superfluous. Such a slide-bar device causes a substantial amount of friction. Also, a duplicator which gives a much larger vertical working space than any known machine is thus achieved.
• Figures 3 and 4 show two different elevation views of the machine.
• Figure 5 shows the combination arm 7 in the extended oosition with the inner section 7 1 and the outer section 7 2
• the three-dimensional duplicating milling-machine consists of a column 1 and a base-plats 2.
• the column 1 is equipped with an upper horizontal table 3 for the original and a lower horizontal cutting table 5.
• a combination arm 7 is mounted.
• the table 3 for the original, the cutting table 5 and the combination arm 7 can be moved vertically and horizontally on the column 1 as they are mounted on said column with split-bushings 3, 23, 5.
• the combination arm 7 consists of two sections, an inner section 7 1 and an outer section 7 2 .
• the inner section 7 1 consists of an articulated arm with two horizontal articulations, a first articulation 6 and a second articulation 9, while the outer section 7 2 of the combination arm 7 consists of a vertical double articulation 10, 11, 12, 13 and of a support 15 for the machine.
• a coordinator arm 4 By means of a coordinator arm 4, the movements of a feeler 17, which follows the original's contours, are. transferred to a cutting tool 21 and the combination arm 7.
• This coordinator arm 4 is U-shaped to be able to move clear of the table 3 for the original. Its lower extremity is linked to the combination arm 7 through bracket 13.
• a feeler 17 is fixed, positioned above, the table for the original.
• the feeler is vertically adjustable and is always on the same centre line is the cutting tool 21.
• the feeler regulates the cutting depth for the cutting tool by means of an adjustable screw 18 which lifts or lowers the feeler.
• an adjustable counterweight 16 is fixed to the section arm 11 at point B.
• the manually induced displacement of the feeler 17 will be transferred through the U-shaped coordinator arm 4 to the outer section 7 2 of the combination arm 7, and through the vertical double articulation 10,11,12,13 and the horizontal articulation 9.
• the machine is thus capable of both vertical and horizontal displacements. Through the inner section 7 1 of the combination arm and the first articulation 6, the machine effects horizontal displacements only.
• An adjustable retaining screw 24 regulates the cutting depth on the blank.
