METHOD OF FORMING EMERY-WHEELS.
SPECIFICATION formingpart of Letters Patent No. 467,254, dated January 19, 1892.
Application filed June 15, 1891. Serial No. 396,348. (No model.)
To all whom it may concern.-
Be it known that I, SOHUYLER G. I-Ionons, a citizen of the United States, residing at Ponnae, in the county of Oakland and State of Michigan, haveinvented certain new and useful Improvements in the Method of Forming Emery-WVheels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to an improved method of forming grinding-wheels; and it consists in the certain peculiar features of construction and arrangement of parts more fully de scribed hereinafter, and definitely pointed out in the claim. I
The object of my invention is to form a grinding-Wheel of emery or analogous material in such a manner that the danger of breaking or cracking is in a measure overcome and the connection between the web and hub improved.
IIeretofore it has been the practice to mold the material of which the wheel is made into the groove of a hub, one wall of which is detachable, and which is secured in place after the material is packed in the mold. The material is then allowed to become hard. In this case the drying causes the material to contract and the wheel becomes. loose on the hub, and it is quite impossible to get the flanges perfectly true. It has also been the practice to pack or mold the material in a grooved felly and allow the same to become hard, the material in this case being in a thin layer. In my improved method I seek to overcome these as well as other objections heretofore existing.
I have illustrated an emery-wheel produced by my method in the accompanying drawings, wherein- Figure 1 is a perspective view of a hub, and
Fig. 2 is a vertical central section through a complete wheel.
A represents the metallic hub; B, th e flanges; C, the web; D, the bore of the hub, and E the securing portion of the web.
I first take a grooved metallic hub having its flanges at the sides of the groove made integral or permanently secured to prevent any movement of the same. I then place the hub in a mold, the inner face of the under flange being flush with the bottom of the mold. I then force into and fill the entire groove between the flanges with the material to conhub, is subjected to a gradually-increasing degree of heat until the binding agent fills the interstices of the wheel, and owing to the heated condition of the hub the material adheres thereto. The wheel is then allowed to cool in a temperature of about 80. Theiron of the hub contracts more than the mixture, owing to the fact that the interstices between the particles of the mixture have become filled with the silicate, thereby tightly binding the material in the hub. The adhesion of the material to the hub prevents the same from becoming loose on the hub when the same is rotated at a high speed and pressure is brought to bear on the periphery. The gradual heating of the entire wheel, including the hub, l have found makes a complete, solid, and permanent union between the web and hub Without bulging, cracking, or in any manner affecting the condition or shape of the web.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
The herein-described method of forming grinding-wheels, consisting of foreing'the material of which the Wheel is composed into a groove in a metallic hub, subjecting the material and hub to gradually-increasing degrees of heat, and finally permitting the same to cool, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
SOHUYLER G. HODGES.
