DANIEL II. REDMOND, OF PHILADELPHIA, PENNSYLVANIA.
FURNACE F'ORHEATINAG METAL RODSVl SPECIFICATION forming part .of Letters Patent No. 576,152, dated February 2, 1897.
Application filed. January 31, 1896. Serial No. 577,545. (No model.)
.To all whom, it may concern:
Be it known that I, DANIEL H. REDMOND, a
, citizen of the United States, residing at the V vention comprises apparatus consisting of the combination of parts hereinafter described and claimed.
The nature, characteristic features, and scope of my invention Will be more fully understood from the following description,taken in connection With the accompanying drawings, forming part hereof, in which- Figure l is a longitudinal sectional viewof apparatus embodying features of my invention. Fig. 2 is a transverse sectional view taken on the line 2 2 of Fig. l, and Fig. 3 is a longitudinal sectional view of apparatus embodyinga modication of my invention.
In the drawings, ct is a furnace provided with a combustion-chamber, as a', an offtake, as CL2, and a heating-chamber, as as. These are well-known parts of a furnace and may be variously constructed and arranged, since they do not, per Se, constitute novelfeatures of my invention.
To carry my invention into effect, I provide withinthe heating-chamber cinclinedways.
As shown in Figs. l and 2, the inclined Ways comprise the floor a4 of the heating-chamber a3. As shown in Fig. 3, the inclined ways, comprise inclined tracks or guides a5, raised above the floor a6 of the heating-chamber. From the foregoing it is obvious that the inclined Ways may be variously constructed.
b are carriers, pipes, or tubes adapted to contain a supply of the rods or the like, c, which are to be heated, and While it is immaterial for what purpose the rods are to be heated, still, for the sake of description, I may state that rods destined for use as unibrella-ribs may be advantageously heated for subsequent tempering by means of apparatus embodying featuresof my invention.
d and e are respectivelyinlet and outlet apertures or openings which may be provided riers is insured.
with doors and which are located at or near the extremities of the inclined ways and afford means for the insertion `and removal of the pipes or tubes b. v
The mode of operation of apparatus en bodying features of my invention may be described as follows: A numberof pipes or tubes b are charged with rods or the like, and are inserted into the furnace by Way of the aperture d. During the course of the operation one or more of these pipes or tubes is Withdrawn from the furnace by Way of the opening e and another charged pipe or tube is inserted to take its place by way of the door d.
vClearly each tube or pipe gravitates and rolls as pipes or tubes are withdrawn from the door e along the inclined Ways, and is thus not only caused to present all portions of its surface to the flames, but also to turn the rods or the like contained within it .so that all portions of their surfaces become evenly heated. The
advantages derived by my invention are numerous,I and among them I may state that since the tubes or pipes roll under the influence of gravity along the inclined Ways it is not necessary for the attendant in charge to turn them. This of course effects a saving of labor, and, moreover, obviates the necessity of providing a large opening through which the attendant would insert tongs for turning the pipes or tubes and through which drafts of cold air would enter. It may be remarked that the construction illustrated in Fig. 3 permits the iiames to have access above and below the pipes or tubes, whereas in the construction of Fig. l the flames pass over the top of the pipes or tubes; but since the tubes in rolling on the inclined Ways are repeatedly turned over and over this difference is not important, and uniform heating of the rods or other contents of the pipes, tubes, or car- The flames or hot gases traverse the heating-chamber a3 from the cornbustion-chamber at one end to the offtake at the other end, so that this combustion-chamber is highly heated. The inclined Ways terminate at the end of the co mbustion-chamber near the offtake, and there is a door e near the end of the inclined Ways and through which the carriers, pipes, or tubes b are Withdrawn in a highly-heated state, so that their contents may be tempered.
roo
It will be obvious to those skilled in the art to which my invention appertains that modicatious may he made in details without departing from the spirit thereof. Hence I do not limit myself to the precise construction and arrangement of parts hereinabove set iorth, and illustrated in the accompanying drawings; but,
Having thus described the nature and ohjects of my invention, what Iclaim as new, and desire to secure by Letters Patent, is-
The combination in a furnace for heating rods and the like, of a combustion-chamber, a heating-'chamber having communication at one cud with the combustion-chamher through the side wall of the latter, an offtake In presence of ALFRED J. VILKINsoN, K. M. GILLIGAN.
