SPECIFICATION forming part of Letters Patent No. 680,863, dated August 20, 1901. Application led December 3l, 1900. Serial No. 41,645. (No model.)
To @ZZ whom t may concern:
Be it known that I, HENRY W. HONEYMAN, a citizen of the United States, residing in the city of Pawtucket, in the State of Rhode Island, have invented a new and useful Improvement in Grinding Devices, of which the following, with the accompanying drawings, is a description.
My invention is designed to be run in an ordinary engine-lathe to grind interior circular surfaces, such as boxes, bushings, the.
In the accompanying drawings, Figure l shows my invention as placed in a lathe in position to run. Fig. 2 shows the device itself, partly in section. Fig. 3 is intended to show how it operates upon the work; and Figs. 4 and 5 are views, partly in section, of portions of the device more fully hereinafter explained.
The device consists, essentially, of a bar or shaft A, upon which is mounted loosely, so as to rotate upon it, a sleeve B, the shaft A being combined with mechanism for supporting it upon the centers of a lathe more or less eccentrically, as desired. The sleeve B also carries a small pulley D for a power-belt, and to prevent friction and Wear and to facilitate repairs it is convenient to place a bushing, as E, Fig. 2, made of some more or less anti friction metal, upon the shaft A, so that the sleeve B may be run upon the bushing.
Upon each end of the shaft A is a head F, constructed with a slideway across its face, in which there is a sliding piece Gr, (see particularly Figs. 3, 4, and 5,) having recesses for the lathe-centers These sliding pieces are set in position by means of the screws H, workingin threads passing through their centers, and the screw-heads may begraduated, if desired, so that both may be turned an equal distance. Set-screws K, Figs. 1, 2, and 5, are provided to hold these slides when brought into proper position.
The operation of the device is as follows: The article Whose inner circular surface is to be ground (represented in the drawings as a half-bushing X) is placed upon the lathe-carriage, as shown in Fig. 1,in order to be given the usual longitudinal motion. My grinding device is mounted in the lathe by placing the recesses in the slides Gr upon the lathe-centers, and a dog L upon the face-plate of the lathe will cause the grinding device to revolve around the lathe-centers with a motion more or less eccentric to the center line of the device,accordin g to the distance the plates G have been moved by the screws H, so as to carry the recesses from the center line of the shaft A. The amount of the eccentricity required in any given case depends upon the internal diameter of the surface to be ground and the relative size of the emery-wheel O. Fig. 3 illustrates this, the circle made up of the inner surface and the dotted line completing it representing the eccentric path taken by the grinding-point of the wheel O, caused by the eccentric position of the recesses for the lathe-centers. A power-belt is then placed upon the pulley D to drive the sleeve B and attached Wheel C at the usual high speed for grinding.
As already stated, the work illustrated in the drawings is a half-bushing; but the device will Work equally Well upon a solid round bushing by passing it through the work before placing it upon the lathe-centers. It will be observed that the emery-wheel is always smaller in diameter than the internal surface to be ground and always runs at a much higher speed than the lathe in which my device is mounted.
l. A grinding device consisting of a shaft and means by which circular motion eccentric to the center of the shaft is imparted to it, an emery-wheel mounted to rotate upon the shaft and means to rotate the wheel independent-ly of the eccentric motion of the shaft.
2. A grinding device consisting of a shaft, pieces having recesses for lathe-centers which are adjustable across the shaft to give the shaft when mounted in a lathe a circular motion more or less eccentric to its center, an emery-wheel mounted upon the shaft, and means for rotating the emery-wheel upon the shaft.
