Abstract: The method of transferring biological specimens onto leather by using a specialized singe plate as disclosed in U.S. Pat. No. 3,298,881 entails wetting a selected section of leather with water and applying the smooth side of the wetted leather on the indented biological imprints provided by the above mentioned plate. Then, by using a press which applies equal amounts of pressure to the entire surface of the afore mentioned plate and leather, an image of the biological specimen is transferred onto the leather itself. The leather is permitted to dry, thus, setting the transferred image, and stain or dye is applied to the leather bringing out the intricate details of the image of the biological specimen, thus, creating a flexible 3-D specimen for scientific study or other endeavors.

The apparatus applies sufficient force to all of several dies, each of which provide different resistances to leather penetration to develop equal displacement of each of such dies into the leather and thereby provide embossed structure of uniform characteristic by all of said dies to produce a particular ornamental and decorative effect. The dies may be readily and rapidly replaced for a variety of names to different leather strips.

Abstract: A machine for producing a strand of fine leather yarn from a leather disc is disclosed. The machine includes a rotatable turntable with an array of suction holes in its upper surface for receiving the leather disc, stiffening it for cutting and tightly gripping it for rotation with the turntable. A cutting wheel is positioned just above the turntable and is rotatably driven on an axis lying generally radially with respect to the turntable. A frame above the turntable supports the cutting wheel and provides for advancement of the cutting wheel radially inwardly as the cutting of leather yarn from the peripheral edge of the leather disc progresses. The speed of inward advancement of the cutting wheel is maintained at a fixed ratio to the speed of rotation of the turntable, so that a constant width of leather yarn is obtained. The advancement may be by means of a rotatable screw shaft linked mechanically to and rotatably driven by the driving means for the turntable.

Preferably, a bracket device is associated with the skinning knife to maintain the straight path of the piece as the skinning knife works on it.

Abstract: A leather product decorated with predetermined indicia and a method of making the product. Preferably, a leather belt is provided with a liner attached thereto along a predetermined section of the rear of the belt to define a pocket. Decorative indicia such as letters, symbols, or the like are then marked on the belt immediately opposite the liner. A resistant cutting strip inserted into the pocket facilitates filagreeing by enabling spaces between the marked indicia to be removed through cutting or chiseling without damaging the belt. After unwanted material between the desired decorative indicia has been removed through filigreeing, the cutting strip may be simply removed from the pocket. In a preferred embodiment of the invention the decorative indicia may be colored prior to removal of the liner, and/or a background strip of predetermined color may be drawn into the pocket as the liner is removed to highlight the filigreed decoration.
