Separate lacquering of the The frame illustrated in Fig. 1 is a typewriter members is much easier to accomplish than the frame consisting mainly of two side members I, lacquering of the entire cage-like frame which a front member 2 removably connected to the side members and surrounding the keyboard on occupies a considerable open space. A ?nish lac quering of the joints is not necessary because the three sides, a rear member 3 also removably con nected to the side members I, and a number of lacquered recesses Ill, l5, or projections I6 of the transverse members 4, 5, 6, ‘l, and 8 for support ing working parts and internally bracing the 40 frame. At abutting places of the main outer members I, 2, and 3 of the frame recesses 50 are provided in the surfaces of the machine which are external and visible when it is ?nished, these recesses ex 45 tending along the length of the butt joints 9. These recesses 10 give the advantage that any ir regularities and projecting edges are no longer visible and cannot be objectionable. Although such irregularities and projecting edges are gen— 50 erally of tri?ing order, they can hardly be avoided in assembling a frame from a plurality of butt joined members and heretofore they had to be re moved by ?ling or polishing as they detracted from the appearance of the machine. The recesses may consist of shallow grooves I0 55 10 15 0 25 35 singly lacquered members i, 2, 3 conceal the joint scams 9. The pleasing appearance of the lacquered external surfaces of the ?nished frame is in nowise impaired by the recesses or projec tions extending in regular pattern, on the con trary these recesses o-r projections have a dec orative aspect. The material of which the frame parts are 45 made comprises any metal which is universally used in the present day manufacture of frames for'typewriters, calculating machines, etc. Fur thermore the frame parts can be connected to gether by any known means and, for example, as shown in Fig. 1 screws 9' are used at the back and a hinge construction II to M at the front. 0 I claim as my invention: 1. A. frame for typewriters, calculating ma chines and the like, comprising a plurality of 55 2 2,112,351 members abutting each other forming abutting lines at the external surface of the frame, parts of the external surfaces of two abutting members near an abutting line lying in the same plane, and one of the abutting members being provided Cl with a strip along the abutting line having a non co-planar surface with said parts for placing the abutting line into the edge of a re-entering angle. 2. A frame according to claim 1, in which the non co-planar surface is counter-sunk below the external surface of the assembled frame. 3. A frame according to claim 1, in which the non co-planar surface is above the external sur face of the assembled frame. 4. A frame according to claim 1, in which the plurality of members are lacquered before the frame is assembled. RICHARD S'I’UHLMACHER.
