Description: |
| This machine will give the greatest facility in scribing mortises, tenons, &c as when the required number of cutters or scribers are inserted in the carriages and set in the required positions the whole of the mortises or tenons may be scribed on one side or edge of the stuff by one stroke of the machine, and by shifting the stuff the other sides or edges may be scribed in a similar manner. Any number of pieces such as the stiles of doors, sashes, shutters, tables, bedsteads, can be scribed so as to correspond accurately with each other. The operation of scribing when performed by hand requires great care and attention and is usually assigned to the best workman, but when performed by my machine might be done by a strong lad or by a man having no mechanical skill, all that will be necessary will be to keep the pieces of stuff (which will previously be planed and the ends squared) close to the rests and stops |
