RIBBED PIPE.
SPECIFICATION forming part of Letters Patent N0. 679,350, dated July 30, 1901.
Appliation filed April 26, 1900l Serial No. 14,402. (No model.)
T0 all whom t may concern.'
Be it known that I, WILLIAM B. WILLIAMS, a citizen of the United States,residing.at Reading, in the county of Berks and State of Pennsylvania, have invented or discovered certain new and useful Improvements in Ribbed Pipes, of which improvements the following is a specification.
It is customary to employ pipes as the supports for billets, dac., in furnaces where it is desired to shift the billet or other article from place to place. As the pipes are maintained at a temperature considerably belowthat of the furnaces by the Water circulating through them, it is evident that the portions of the billets or other articles resting on the pipes will be prevented from being heated to the same temperature as the other portions. Such relatively-unheated portions are known as black spots, and their extent is proportional to area of contact between the billets and the supporting-pipes. As these black spots tend to prevent an even reduction of the billets, it is desirable to reduce the contacting areas between the billets and pipes to as great an extent as possible and also to reduce as far as practicable the difference in temperatures of the billet-support and the furnace. It has been attempted to attain these desirable ends by securing a narrow metal strip on the pipes by welding or riveting, but without success, as in all cases the strips are burned or torn olf.
The object of the present invention is to provide a pipe with a rib or ribs formed integral therewith.
The invention is hereinafter more fully described and claimed.
In the accompanying drawings, forming a part of this specification, Figure l is a sectional elevation of a furnace having improved pipe-rails arranged therein. Fig. 2 is a transverse section of the furnace, the plane of section being indicated by the line II II, Fig. 1. Figs. 3, 4, 5, G, and 7 illustrate different forms of pipe supports.
In the practice of my invention the pipe supports l are formed with a rib 2 along one side, or two ribs 2 2a may be formed on opposite sides of the pipe, so that when the rib on one side is worn down the pipe can be reversed. These ribs may be made of any desired transverse contour, as will be seen by reference to Figs. 3 to 7, inclusive, which illustrate different shapes. These ribbed pipes may be formed in different ways-as, for example, a pipe formed in any of the ways known in the art may be heated to a plastic temperature and then drawn or forced through die or bell or between rolls suitably constructed to compress or squeeze together portions of the pipe to form a solid rib 2, as fully described and shown in application, Serial No. 14,404, filed April 26, 1900. By suitably constructing and proportioning the portions of the bell, dies or rolls which operate on the walls of the pipes to form the rib the opposite walls of the rib may be forced together, forming a solid rib, as shown in Fig.4.
As described and claimed in applications, Serial Nos. 14,403 and 14,405, led April 2G, 1900, the ribbed pipes may be provided by forming ribs on the pipe-blank: and then bend ing and welding said blank in the usual Inanner to form the complete pipe. This method is particularly applicable for manufacture of double-ribbed pipes. and 7.)
As shown in Fig. 5 and as described in application Serial No. 14,404, above referred to, two ribs 2 2a may be formed by suitably bending or swaging opposite sides of a pipe. As set forth in said application, the ribs are formed by forcing the heated pipe through a bell or die having a suitable shaping-matrix or between rolls having a pass of the desired contour. The ribs thus formed on the pipe cannot be torn away without the actual de struction of the pipe itself. As the bearing portion of these ribs can be made narrow, even to a knife-edge, if desired, the contact areas between the pipes and billets will be reduced to a minimum, and such bearing portions being at a relatively considerable distance from the cooling medium circulating through the pipe will be heated nearly to the temperature of the furnace.
It will be understood that the ribbed pipe (Shown in Figs. 5
the pipe,sueh rib forming a Wearing-surface, substantially as set forth.
In testimony whereof I have hereunto set my hand.
WILLIAM B. WILLIAMS.
