Application April 11, 1941, Serial No. 387,993
3 Claims. (CI. 9146) My invention relates to abrasive wheels of a type formed by coating the peripheral surface of the Wheel with granular abrasive affixed to the wheel with a suitable adhesive. In so forming the wheel it is necessary to coat the peripheral surface thereof with adhesive, an operation that has hitherto been performed manually.
- It is the object of my invention to provide mechanism for performing this coating operation, thus not only reducing the cost of coating but obviating a tedious and disagreeable manual operation.
With the foregoing and related objects in View, the invention resides in the mechanism illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a machine constructed in accordance with my invention, certain parts being broken away and sectioned for convenience in illustration; Figure 2, a rear view thereof partially in section; Figure 3, a partial sectional view taken along the line 33 of Figure 1; and Figure 4, a side view of a portion of one of the wheel retaining arms.
The mechanism comprises a frame I supported on legs 2 and designed to support a basin or tank 3 and a glue pot 4 positioned in the tank 3 and spaced therefrom. The tank 3 is preferably provided with heating elements 5 which may be steam coils, electrical units or other suitable device. The tank 3 is designed to be filled with water which is heated by means of the heating element 5 whereby to keep the adhesive, contained in the glue pot 4, at a proper temperature. Of course, if the adhesive used is of a type which does not require to be heated for use, the tank 3 and heating elements 5 may be dispensed with and the glue pot 4 alone employed.
The frame I is provided with a pair of rearwardly and upwardly extending brackets 6 and I journaled to receive a shaft 8 extending therebetween. Extending between the brackets 6 and I and pivotally mounted on the shaft 3 is a frame comprising a housing 9 and a pair of forwardly extending arms I0 and II attached thereto. The arm II] is provided with a lug I2 which engages a stop I3 on the bracket and limits the upward rotation of the arms IE! and II. The housing 9 is provided with a rearwardly extending arm I4 on which is slidably mounted a counterweight I5, a set screw I6 being provided to hold the counterweight in any desired position of adjustment.
Mounted on cross bars 40 extending between the legs 2 and controlled by reversing switch I! is a reversible motor I8 which is connected to a 7 speed-reducing gear I9 of conventional type. The speed reducer I9 is provided with a pulley or sprocket wheel 28, connected by a belt or sprocket chain 2| to a pulley or sprocket wheel 22 mounted on the shaft 8. A second pulley 39 is mounted on the shaft 8 and is connected by a belt 23 with a pulley 24 which is mounted on a shaft 25 journaled in a boss 26 on the extremity of the arm Iii. A chuck 21 is mounted on the shaft 25 and, in its preferred form, comprises a recess 28 adapted to receive one extremity of an arbor 29 and communicating with a slot 39 adapted to receive a driving lug 3| on the arbor 29 whereby to provide a driving engagement with said arbor.
The arbor 29, at its opposite extremity, is reduced in diameter and provided with a roller 32 held in position by the nut 33 and washer 34. The roller 32 is adapted to enter the slot 35 in the arm II and has a depressed center portion adapted to engage said arm, the outer portions of said roller being of greater diameter so as to overlie adjacent portions of the ann I I and prevent lateral movement of the arbor, as best illustrated in Figure 3.
The arm II is fitted with hand grip 36 near its extremity for a purpose hereinafter described. The sequence of operations in coating a wheel by the use of the above-described mechanism is as follows: The operator, having filled the glue pot 4 with a suitable adhesive, starts the motor I8 by means of the switch I'I, inserts the arbor 29 into the abrasive wheel 31 to be coated, then inserts the arbor in the chuck 21 with the driving lug in the slot 39 and inserts the opposite extremity of the arbor in the slot 35 whereby the arbor and abrasive wheel are rotated by the motor H5. The speed of rotation may vary within wide limits, but I prefer to use such an arrangement of motor speed, reducing gears and pulley relationships as will give a rotation speed of approximately twenty revolutions per minute to the arbor. The operator then grasps the hand grip 36 and forces the arms I3 and II downwardly, the housing 9 rotating on the shaft 8 until the abrasive wheel 31 contacts the adhesive in the glue pot 4, as shown by the dotted line position of Figure 1. It will be understood that the counterweight I5 is adjusted so as to slightly overbalance the weight of the wheel, arbor and arms I0 and II and cause the latter to return to the upper or full line position when the hand grip 33 is released. The operator then holds a brush or similar tool in contact with the rotating periphery of the wheel 31 thereby forcing the adhesive into the pores and interstices of the wheel. A tool rest 38 may be provided for resting the brush during this process. The operator then reverses the direction of rotation, by means of the reversing switch l1, and repeats the brushing operation with the wheel rotating in the opposite direction. The operator then releases the hand grip, allowing the wheel to be swung back to the upper position, removes the arbor and Wheel from the arms and removes the arbor from the wheel, the wheel then being in condition to be coated with abrasive by any suitable method.
The specific details herein disclosed are for the purpose of illustration only, and I do not desire to limit myself to said details, as it .is obvious that various modifications may beniade therein without departing from the essential features of the invention, as defined in jtheap pended claims.
I claim: it h wheel, means for pivoting said frame whereby to cause the periphery of said abrasive wheel to contact said adhesive, and means for normally holding said frame in a position such that the abrasive wheel is out of contact with the adhesive.
2. Mechanism for with adhesive comprising, in combination, a container for holding adhesive, means for supporting said container, a frame pivotally mounted on said supporting means, an arbor adapted to receive an abrasive wheel, a shaft journaled in said frame, means comprising a chuck attached to said shaft for supporting said arbor in said fra'me means comprising a motor for driving said shaftand-said chuck whereby to drive said wheel, and means for pivoting said frame whereby to causeithe' periphery of said abrasive wheel tq co ntact said adhesive.
3. Mechanism for coating abrasive wheels with adhesive comprising,in combination, a container for holding-adhesive, means for supporting said container, a frame pivotally mounted on saidsupporting means, an arbor detachably mounted on said frame and adapted to receive an abrasive wheel, means whereby saidframe-may be pivoted to cause the periphery of said Wheel to contact said adhesive, and means for rotating said arbor.
