from The Century Dictionary.
- noun A power-machine for making nails, spikes, brads, or tacks.
Sorry, no etymologies found.
After the patent is allowed he may find the entire combination of the nail-machine without the counter disclosed in a patent for a nail-making machine, so that as a nail-making machine this new patent is of no value as a reference.
The applicant may have made a complete new organization of nail-machine and may seek a patent for the total combination.
The most natural procedure, at first thought, would be to classify on the totality of the showing, in which case the application for the nail-machine, supposed above, would be assigned to nail-making.
If no application save that of the nail-machine be pending, no duplication of patents occurs, but the labor of search is increased by reason of the unfamiliarity of the examiner with the inventions he has to search.
