` UNITED STATES PATENT OEEIcE.

NA'IIIANIEL FO UST, OF LOCK HAVEN, PENNSYLVANIA, ASSIGNOR TO NEIVTON FREDERIOKS, OF SAME PLACE.

TUYERE-IVIACHINE.

SPECIFICATION forming part of Letters Iacent No. 417,164, dated December 10, 1889.

Application led May 25, 1889. Serial lIo. 312,134. (No model.) I

10 all whom t may concern' 3e it known that I, NATHANIEL Foisr, a citizen of the United States, residing at Lock Haven, in the county of `Clinton and State of Iennsylvania,l1ave invented certain new and useful Improvements in rluyere-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Figure 1 is a side elevation, partly in section, of the machine. Fig. 2 is a horizontal section of Fig. 1 through the Working' parts. In this vieiv the needles are shown as driven through the clay in the tuyeremold. Fig. 3 represents details showing the casing which fits into the mold7 and the Wire rods which are placed in the tuyere when removed from the mold; Fig. 4, a vertical section of one of the tuyeres. Fig. 5 is a detail in longitudinal section, showing the case placed inside the mold. with the case inside.

This invention relaties to improvements in machines for making tuyeres; and the novelty consists in the construction of the several parts, their combination, and the machine as an entirety, all as will now be described, as Well as pointed out in the claims.

In the accompanying drawings, A denotes any suitable framework in which the mold Il is adapted te rest and be tilted up and down on the trunnions I), which have suitable bearings in the upper rails or parts of the frame A. This mold has a cap o and h2 at its respective ends. These caps may be hinged to the mold, as new shown, and be held closed by a catch if; but I do not wish to be limited to any precise details or meehanism for att-aching the caps in position, it being only essential that they shall be so adapted to the mold that it can at either end be easily opened or closed, as desired. Each of these caps is perforated at o".

The needles Care attached at one end to the head I). They are of suitable length to pass entirely through the materia-l in the mold B when the tuyere is being made. They are so fitted into the head I) that their opposite ends Will when the needles are moved Fig. (i is a cross-section of the mold` forward enter 'the openings b" in the caps of the mold. This motion, as well as'the return movement, is accomplished by means of the screws E being turned by the gearing F and pulleys G, thereby moving the head D along the screws in any usual or ordinary manner.

In operating this machine the cap on the outer end of the mold having been removed or turned back the sheet-metal case II is in- 6o serted, so that its flaring end iits in the ilarin g end of the mold, and the cap then replaced and secured in position. The mold is then tilted, and the cap at the other or inner end being removed or turned back, clay, cement, 6 5 or any other material of which the tuyere is to be made is put or forced into it. Then the mold has been iilled, the cap is returned to its place and the mold turned down into its horizontal position,where it is stopped by 7o the lug b, resting on the top bar of the frame A. At this moment the needles are caused to move forward and are made to pass through the perforations in the caps at that end of the mold (said perforations acting as guides) and 7 5 also entirely through the material in the mold, as above stated. Then the operation has been fully completed, the needles are Withdrawn. The mold can now be tilted and the cap at the outer end taken off or turned away, 8o and the ease Il, with the tuyere I inside, is now taken out of the mold, and after the wires or rods K, each. of proper size and length to fill one of said holes, have been placed in the holes i in the tuyere and all of said holes 85 Iilled it can be set awayfor drying. When p properly dried, the wires are removed and thc tuycre removed from the casing and is ready for use.

The advantage of using the wires is that 9o in drying the holes will be kept straight and true. rlhis a matter of large importance in this class ot' devices, because' it an essential point that the airpassages shall be as free and unobstructed as possible.

In the detail of pivoting the mold, also of taking out the tuyere from it, there may be manifold merely mechanical changes over what I have described. The flaring end b5 of the mold may be located opposite-ly to what roo .is now shown, so that the tuyere can be removed at the other end of the frame. In

many like minor details Changes may be made without departing from the nature o1' scope of my invention; also, the mold may be used with one or without any cap.

5 vliet I claim isl. In combination with the mold, a metal easing adapted to fit into the same, as and l'oi the purposes set forth.

2. The combination of the mold having 1o perforated caps and needles opemted, ns set forth, with the sheet-metal ense Il, as mid for the purposes set fol-ih.

the mold B, lin-ving trunnions Z1, and L flaring end b5, caps D and U3, and the ease Il, and l the needles and operative mechanism, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
