'MOUNTING QF ABRASIVE WHEELS.
Patented Nov. 18, 1913. i
Original application led September 21, 1911, Serial No. 650,563. Divided and this application led December 1e, 1912. serial No. 736,909.
To all 'whom t may concern:
Be itA known that I, HENRY K. SPENCER, a citizen of the United States, and a resident of Dorchesten, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Mounting of Abrasive Wheels, of which the following dcscription, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like' parts. l
This inventionrelates to the mounting of abrasive wheels, and will be best understood by reference to the following specification, when taken in connection with the accom.
ianying illustration of one specific embodiment thereof, while its scope will be more particularly pointed out` in the "appended claims.
This application is a division of my prior, co-pending applicatiomSerial No. 650,563, filed September 21, 1911.
rlhe drawing shows in central vertical section an abrasive wheel and mounting therefor, embodying my invention.
Referring to the drawing, and to the illustrative embodiment of my invention there shown, 1 is a spindle, to which a usual face plate 2 is secured in any suitable manner. An abrasive wheel 3, which may beof any usual or desired form, is secured to the face plate in a novel manner. The abrasive wheel 3 is herein shown as formed with straight sides, that is to say, its periphery is cylindrical.` Herein, the wheel is secured to a retaining ring 4, which in turn is secured to the face plate 2. The retaining ring 4 is provided with a flange 5, which overlies the yedge of the wheel, and is tapeied with reference thereto, so as to provide an angular space whichv is filled with cementitious .material 6, such for example as ordinary Portland cement.
While the retaining ring may take other forms, the angular space just referred to is preferably formed byV roviding lthe ring internally with a recess if, having a circumferential surface 8, which is `herein tapered or inwardly widened Preferably, the end of the abrasive ,wheel is first covered with a thin layer of cement, and the wheel is then placed'in the ring, this thin layer of cement being used for the purpose of leveling, or truing, the wheel so that its face shall lie in a plane at right angles to the axis of the spindle 1. The. cement fillino' 6 is then inserted, and the same mass allowed to harden. This secures the wheel to the ring by means of a cemented lockjoint, which holds the wheel. securely in place. Owing to the porous granular nature of the abrasive substance of the wheel, the Portland cement, when hardened, adheres very firmly thereto, but naturally does not adh'ere firmly to the surface of the retaining ring,'which is therefore made of such lform. as to interlock with the cement filling and efectually prevent the wheel, with its tapered ring of cement, from becoming dislodged. If desired, the surface 8 may be roughened, so that the cement will bond thereto. This roughening may take 'any ypractical form, but herein is produced by 'worn out, the 'cement and remnants of the wheel may be chipped out, and the retaining ring-used again for another wheel.
While I have herein shown and described one embodiment of my invention for illustrative purposes, and have disclosed and discussed -in detail the construction and arrangement incidental to one specific application thereof, it is to be understood that the invention is limited neither to the mere details or relative arrangement of'parts nor to its specific embodiment herein shown, but that extensive deviationsy from the illustrated form or embodiment of the invention may be made without departing from the. principlesv thereof.
Having thus described my invention, what I claim and desire by Letters Patent to procure is 1. The combination with a grinding Wheel, ofa driving spindle therefor, a face plate, and means including a cemented lockjointV attachment for securing the grinding wheel to theface plate.
2. The .combination with a driving member, a grinding wheel, and a holding device for securing the wheel to the driving member, said device having a cement-filled joint between the same and the circumferential surface of the wheel.
. 3. The combination with a grinding wheel, of a face plate, a retaining rlng having a tapered wall vadapted to overlap the wheel, and a cement filling between the wheel and the wall.
4. The combination with a driving member, of a face plate, a retaining ring, and a grinding wheel having a circumferential surfaceA cemented to the retaining ring.
5. The combinationwith an abrasive Wheel, of a body of cementitious material adhering to the periphery of said wheel, and a holder with which said cementitious material interengages.
6. The combination with an abrasive wheel, of a holder provided with a lateral recess, and a body of cementitious material adhering to the periphery of said wheel and extending laterally into said recess.
7. The combination of holding means having an inwardly widened recess, a wheel extending into said recess, and a body of cementitious substance adherin to the sides of said'wheel, and engaging t e sides of said recess.
8. The combination with a wheel having a cylindrical surface, 'a holder provided with tapered sides, and a body of cementitious substance adhering to the cylindrical surface Iof said wheeland engaging the sides of said recess.
In testimonywhereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
HENRY K. SPENCER.
