COLD-AIR BLAST FOR THE PROTECTION OF NAIL-MAKERS.

$PECIPICATION forming part of Letters Patent No. 317,916, dated May 12, 1885.

Application filed March 11, 1885.

{[0 aZZ whom, it may concern.-

Be it known that 1, Jason AL'IMEYER, of

Benwood, in the county of Marshall and State of West Virginia, have invented a new and useful Improvement in Air-Cooling Apparatus; and I do hereby declare that the following is full, clear, and exact description of the same.

My invention relates to the ventilation and cooling of the air surrounding the workmen while operating hot nail-machines and their attachments, and to the protection of the workmen from the heat radiating from the heated iron about 'the machines. It is designed especially to be used in connection with nailmachines while manufacturing steel cut-nails. While manufacturing nails of this class it has been found necessary to heat the plates or blanks from which the nails are cut to a higher degree than has been found necessary in the manufacture of iron nails. As these plates and the nails after they are cut must be near to the workmen, the high degree of heat is painful and injurious, and from the nature of the work it is impossible to use screens to shelter the workmen.

My invention consists, essentially, in interposing a sheet of cool air between the workmen and the heated iron or other heated ob- 0 jects from which heat is radiated to his person.

. ular description is required. Between these machines, upon the floor, is a pipe, B, which leads from any suitable air-forcing apparatus. From this pipe branch pipes 11 b are led in front of each machine. Both pipes are alike, and a description of onewill suffice for (No model.)

both. Each pipe is joined to the main pipe by flexible connections, so that it may be thrown around either vertically or horizon tally whenever it is necessary to remove the nail-box (J. The branch pipe passes under the foot-rest d on the seat D occupied by the workmen. It is formed with slots or holes, so as to direct a sheet of cool air upward in front of the workman and between him and the machine, as well as between him and the box E, which contains the plates or blanks of steel which are to be used in forming the nails. The end of the pipe is closed; but holes may be made in other directions for driving the air over the box of nails, if desired.

The sheet of cool air rising up constantly displaces the heated air and interposes a shield of cool air between the workmen and the heated objects, thus tending constantly to keep the workmen shielded from the heat, which would otherwise be painful and injurious.

In order to remove the box of nails, the branch is swung around until the box is removed and it can be replaced after the empty box is in position to receive the nails.

The same arrangement of pipes can be used in front of the nail-heating furnace with the same effect, throwing up sheets of cool air in front of the workman.

On the branch pipes b b are secured deflector-plates e 6, extending the length of the nail-boxes and inclining inwardly and upwardly toward the machine, whereby the cool air as it issues from the pipeis directed across the nail-box and up between the machine and the workman, as represented in Fig. 3.

I claim as my invention- The hereinbeforedescribed mode of protecting workmen upon machines of the class described by passing a sheet of cool air between the workmen and the machine and heated objects, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JACOB ALTMIEYER.
