. M. BURNS. Process of Uniting Wrought and Cast Iron.
No. 231,532. Patented Aug. 24, I880.
PErins, FHOTOJJTHOGRAFMER, WASHINGTON D C UNITED. STATES PATENT OFFICE.
MORGAN BURNS, OF HYDE PARK, ILLINOIS, ASSIGNOR OF ONE-HALF OF HIS RIGHT TO OSWELL A. BOGUE, OF SAME PLACE.
PROCESS OF UNITING WROUGHT AND CAST IRON.
SPECIFICATION forming part of Letters Patent No. 231,532, dated August 24, 1880.
Application filed May 10, 1880.
To all whom it may concern Be it known that I, MORGAN BURNS, of Hyde Park, in the county of Cook and State of Illinois, have invented or discovered certain new and useful Improvements in a Process for Uniting Wrought and Cast Iron; and I do hereby declare the following to be a full, clear, and exact description of the invention, that will enable others skilled in the art to which it appertains to understand and make use of the same.
This invention relates to a process for uniting wrought and castliron, the precise nature of which is fully set forth in the following specification.
In order to more fully and clearly explain the nature and object of this invention, referenceis made to thedrawin gs, in which a wagonaxle is shown, by way of illustration, which is composed of a wrough t-iron spindle and a castmetal thirnble-skein united by this process.
Figurel shows a wrought-iron axle, having a cast-iron thimble-skein cast onto the spindle end thereof. Fig. 2 shows an axle of wroughtiron before the application of the cast thimbleskein thereto, and Fig. 3 shows the core used in preparing the mold.
Referring to the drawings, A represents a wrought-iron wagon-axle having a tapering spindle end, as shown in Fig. 2 of the drawings; B, a cast-iron thimble-skein, cast upon and united to the wrought spindle by the process herein described; 0, a shoulder-flange formed integral with the skein B, and D a washer-nut which. serves to retain the wheel in place.
In carrying out my process I prepare the mold in the usual manner, and after the core has been removed from the sand the axle or other article to receive the cast metal is next placed in the mold and the molten metal poured around the same.
Preparatory to placing the wrou ght-iron axle or other article in the mold a thin coating of kerosene-oil and chalkis applied to the sur- (No model.)
face of that part of the wrought-iron which is intended to receive the cast-iron.
The object of coating the surface of the wrought metal with a composition of keroseneoil and chalk is for the purpose of preventing the dampness arising from the molding-sand collecting on and adhering to the surface of the wrought metal, thereby preventing a close and perfect union of the two metals. The oil and chalk also have the effect of preventing the two metals from separating on account of unequal expansion and contraction of the metals during the process of uniting and cooling the same, the metals being allowed to cool in the same manner as ordinary castings.
This process may be employed with great advantage in manufacturing different articles, a wagon-axle being selected as an object and shown herewith to more clearly illustrate the nature of the invention.
When the cast-iron thimble-skein has become too much worn to be of any further service the axle may be heated, then placed on an anvil, and a few blows of a hammer will separate the cast metal from the wrought metal, and a new thimble-skein may be again cast onto the same spindle.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s
The process hereinbefore described of unit ing wrought and cast-iron by first applying to that part of the surface of the wrought-iron which is to receive the cast-iron a coating of kerosene-oil and chalk, then placing the wrought-iron object in a mold prepared in the usual manner, and finally completing the process-by pouring the molten cast-iron around the same, substantially as set forth.
hi MORGAN XS BURNS.
