BLACKSMITHS FORGE.

SPECIFICATION forming part of Letters Patent No. 477,699, dated June 28, 1892. Application filed November 10, 1891. Serial No. 411,491. (No model.)

To @ZZ whom t may concern.-

Be it known that I, VILLIAM J. lTOMEY,a citizen of the United States, residing at Me- Grackcn, in the county of Rush and State of Kansas, have invented a new and useful Blacksmiths Forge, ot' which the followingis a specification.

rl'his invention relates to tuyeres for blacksmiths forges, and is designed as an improvement upon Letters Patent No. 406,767,grant ed to me July 9, 1889; and it has for its object to provide an improved tuyere having several improvements over said former patent that will render the same more complete and morel el'licient in operation, the said improvement being designed to specially improve the water-supplying devices, as well as the cinderboX cap and other minor points of my original tuyere. s

Vith these and other objects in view, which will readily appear as the nature of my invention is better understood, the same consists in the novel construction, combination, and arrangement of parts, hereinafter more fully described, illustrated, and claimed.

In the accompanying drawings, Figure 1 is a perspective view of a forge-tuyere construct ed in-accordance with my invention. Fig. 2 is a vertical longitudinal sectional view of the same. Fig. 3 is a vertical transverse sectional view through the tuyere proper. Fig. f1 isa detail in perspective of the grate-rod cone. Fig. 5 is a horizontal sectional View through the cone-securing screws and einden box.

Referring to the accompanying drawings, 1 designates the body of the tuyere, which is preferably circular in shape and is provided with the concaved cover 2, forming the lire-box ot' the forge and which is fastened by means of suitable bolts 8, passing through the wall of said circularboX-tuyere and fastened to the same. The said concaved fire-box and cover is provided with a downwardly extending neck 4, projecting through and within a perforation 5 in the bottom of the tuyere-casing, and thus forms with the inner wall of said casing an inelosed water-space 6, all of which is constructed in substantially the same manner as the tuyere described in my former patent. A cylindrical einder-box 7 is designed to be located directly beneath the opening through the neck of said fire-box, and the same is provided at its upper end with the radially extending perforated flanges 8, by means of which said cinder-box, which may be either rectangular or cylindrical in shape, is secured tothe under side of said tuyere-box by means of the fastening-bolts 9, which connect said cinder-box with the tuyere in such a manner as to allow the saine `to be adjusted in various positions by turning the saine so that the various anges may be made to interchange places with each other, so that the tuyere may accommodate itself to any position in which the bellows is located. The said cindenbox is further provided with a laterallyextending pipe 10, whichis connected in any suitable manner with a pair of bellows or with a rotary blower of suitable con struction, and the lower end of said cinder-box is further provided with a beveled lower edge 11, that is designed to form a seat for the cone-shaped bottom or cover` 12, provided with a central perforation 13 and the laterally-extending arms 14, to which are connected the weighted cords 15, passing over pulleysl, secured to opposite sides of the tubular cinder-box 7; The cords are provided at their lower ends with suitable weights 17, by means of which said bottom or cover is always normally held in position over the lower end of said cinderboX, and thus providing means whereby accumulations of cinders within the cinder-boX may be easily and readily removed. As in my former patent, theupper end of the cinder-box communicating with thelower end or neck of the lire-box allows the blast of air entering the cinder-box through the pipe 10 to be discharged directly in the center of the bottom of the fire-box. Located in the bottom of said fire-box and directly within thelower neck thereof is the rotary grate 1S, which is mounted upon one end of the vertical operating-rod 10, extending downwardly through the cinder-box and having its bearings in Va suspended cone bearing-block 20, supported centrally within saidcinder-box by meansof the set-screws 2l, passing radially through said cinder-box and impinging against the periphery of said cone bearingblock, which, on account of its conical shape, prevents the cinders from lodging thereagainst and allows the same to fall directly down upon the IOC weight-pressed cover or bottom 12 referred to. The lower end of the operating-rod 19 projects through the central perforation 13 in the bottom or cover 12 and is provided with a crank or handle 23, whereby the same may be conveniently manipulated, so as to rake the fire and cinders and cause the latter to drop into the cinderboX, from which they may be afterward removed through the cover. A Water-supply pipe 23X passes through the bottom of said tuyere-box and communicates with the water-space 6, inclosed between the same and said tire-box, and is connected at its outer end with the bottom of an elevated water tank or reservoir 24, from which water may be supplied from the same through the pipe 23 to the tuyere-box 1, and said supplypipe 23X is provided directly below said tank or reservoir with a drain or draw-olf cock 25, by means of which the water may be drawn otf from said reservoir and from said waterspace when desired.

Circulating and return pipes 26 are connected through the top of the lire-box and tuyere-cover with the inclosed water-space and are curved up over the top of thc tank or reservoir, so as to discharge the returned water into the same and provide a continuous circulation of the water. Said circulating and return pipes are provided at their lowest points with cocks 27, by means of which the water may be drawn olf in order to clean the same or to prevent freezing in the pipes. The uses and ad vanta ges of having an inclosed Water-space and a supplying reservoir or tank are fully Set forth in my former patent and need not be further enlarged upon in the present applieation.

Y The extent and nature ofthe improvements upon my former patent are thought t0 be apparent without further description.

Having thus described my invention7 what I claim, and desire to secure by Letters Patent, is-

1. In a blacksmiths forge, the combination of the tuyere-box, a tubular cinder-box removably connected to the under side of the tuyere-box and provided with a blast-pipe, saidbox being designed to be circularly adjusted beneath the tuyere-box to accommodate the blast, a cover or bottom normally closing said cinder-box, and Weights flexibly connected with said cover and suspended to draw the same against the eimer-box, substantially as set forth.

2. VIn a blacksmiths forge, the combination of a tuyere and fire box having a bottom opening, a tubular cinder box removably connected to the lower or under side of said tuyere-box and provided witha lower beveled seat, a conical cover fitting said beveled seat or lowered end, pulleys secured to opposite sides of said cinder-box, and weighted cords connected to said bottom or cover and passing over said pulleys, substantially as set forth.

3. In a blacksmiths forge, the combination of a tuyere and fire boX having a bottom opening, a tubular cinder-box having a blast-pipe and removably connected to the lower under side of said tuyere-box, a cover or bottom normally closing the bottom of said cinder-boX, suspended weights connected with said cover to hold the same against the cinder-boX, a r0- tary grate located in said bottom opening and having an operating rod extending down through said cinder-box and the bottom or cover thereof, and a conical guide-block suspended centrally within said cinder-boX and adapted to receive said grate-operating rod, substantially as Set forth.

4. In a blacksmiths forge, the combination of a combined tuyere and tire boxhaving an inclosed water-space, a blast-receiving and cinder box removably secured to the under side of said tuyere and tire boX, a cover normally closing the lower end of said cinder-boX, weights suspended from the sides of the cinder-box and tlexibl y connected with said cover or bottom, a water tank or reservoir adjacent to said tuyere and located above'th'e same, a suppl y-pi pe connecting the lower ends of said reservoir with said inclosed waterspace, a draw-off cock connected with said supply-pipe below the tank, circulating and return pipes connected to the top of said water-space and projecting within the top of said tankl or reservoir, and draw-off cocks connected with said circulating and return pipes at their lowest points, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto aliixed my signature in the presence of two witnesses.
