Description: |
| Most of the patents prior to 1836 were lost in the Dec. 1836 fire. Only about 2,000 of the almost 10,000 documents were recovered. Little is known about this patent. There are no patent drawings available. This patent is in the database for reference only.
“For a Strap Cutting and Punching Machine; Charles Angel, Philadelphia County, Pennsylvania, July 15.
We are unable to give a satisfactory description of this machine, as it does not appear that there is any drawing of it in the patent office, although it is absolutely necessary to its validity that one should accompany and make part of the specification. The description is evidently written with much care, and, to himself, the explanations given by the writer, were undoubtedly very clear; but in all instances it requires a peculiar aptitude, and, in many cases, it is impracticable, perfectly to describe a machine, in words, without drawings; and hence the wisdom of that provision of the law which makes the demand for them, absolute.
The cutting machine appears to consist of a piece of wood sliding in grooves, with a cutting knife extending downwards, and sloping back at such an angle as to render the cutting easy; several thicknesses of leather are to be cut at once, there being proper means provided to regulate the width of the straps.
The punching machine consists of a block, sliding up and down between two guide pieces, there being several hollow punches projecting from the lower side of the block, and fixed at proper distances from each other. The block with the punches, is to be forced down by a lever, and afterwards the straps drawn forward, and an. other row of holes punched.”
