METHOD OF TEMPERING METAL.
SPECIFICATION forming part of Letters Patent No. 337,979, dated March 16,1886.
Application filed August 31, 1885.
To aZZ whom it may concern.-
Be it known that I, SAMUEL E. MOWER, of
New Haven, county of New Haven, and State of Connecticut, have invented an Improvement in Methods ofTempering Metal,of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts. to My invention has for its object to effect the partial hardening or tempering of steely metal, either in the form of a strip or of a manufactured article.
My invention consists of a method of hard- 1 ening or tempering steely metal, which consists in drawing the hot metal to be hardened or tempered between asbestus or other noncombustible packing while the edge of the metal to be tempered is kept in or acted upon by the tempering-fluid, the said packing preventing the passage of the tempering-fluid upon the metal above the said packing, substantially as will be described.
In accordance with my invention I have provided a reservoir to contain water or other fluid, the said reservoir having an auxiliary chamber communicating with the reservoir proper, and herein I have shown the said chamber as semicircular in form and covered by metal plates, which are provided with a packing of asbestus, or it may be other equivalent non-combustible material, against which bears snugly the metal as the latter is drawn through the fluid, thereby preventing the said 5 fluid from reaching the metal above the packl have also, in accordance with my invention, rigidly fastened one of the said plates to the reservoir, and have provided the other plate, which projects over the side of the reservoir, with slots, through which screws are extended into the frame of the said reservoir, and have secured to the side of the reservoir springs,which act against the projecting edge of the slotted plate, the said spring being of sufficient strength to firmly press the said plate and its asbestus packing against the metal to be tempered.
As heretofore practiced, metal strips have Serial No. 175,738.
(No Specimens.)
been either completely tempered by immersing the entire strip in the water,orthey have been partially tempered by drawing one edge of the strip against a moistened or wet absorbent band, as in application, Serial No. 175,130.
Figure 1 is a top view of apparatus devised 5 by me for tempering bands in accordance with myinvention; Fig. 2, a section of Fig. 1 on the line as w,- and Fig. 3 shows a piece of metal,
the dart lines indicating the extent to which the metal is hardened or tempered. 6c
The reservoir A, of metal or any other suitable material, is shown as having its top plate convexed at a to form an auxiliary chamber,
a, which communicates with the main chamber B by means of the openings 0. Upon the top of the reservoir A, I have rigidly fastened the plate 0 by means of the screws S, the said plate being extended to near the central line of the reservoir, where its edge is cut away or made oblique, as at c. The plate O, placed at the other side of the central line referred to, is provided with slots I), (see Fig. 1,) through which screws S are extended and screwed to the reservoir A, the said plate being extended beyond the said reservoir, where it is acted upon by springs S, (see Fig. 2,) fastened to the said reservoir by the screws S The plates 0 G are each provided at their edges, near the center of the auxiliary chaniher a, with asbestus or other non-combustible material a, which is herein shown as packed in slots in the said plates; but it is obvious the same might cover the said plates and be secured thereto in any suitable or convenient 8 5 manner, the asbestus packing fitting the metal strip D closely, and serving to keep the water from reaching the said metal strip above the said packing as the said metal strip is drawn through the water or other usual temperingfluid below the said packing.
In the operation of my improved apparatus the metal strip 1), (herein shown as a toothed strip,) after being heated to the required heat for tempering, is run from the furnace (not shown) between the asbestus or non-combustible packing held by the plates 0 O, the lower edge of the said strip dipping into the said consists in passing heated metalthrough water or other fluid between a packing of ashestus or other non-combustible materia1,whereby the said fluid is prevented from reaching the metal above the packing, thereby tempering only a part of the said metalysubstantially as described. I
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
