FRANK L. 'O. WADSWORIH, OF MORGANTOWN, WEST VIRGINIA, ASSIGNOR TO PRESSED PRISM PLATE GLASS COMPANY, 01 NEW YORK, N. Y.,
A CORPORATION OF WEST VIRGINIA.
I APPARATUS FOR POLISHING AND GRINDING GLASS.
Specification of Letters Patent.
Patented June 16, 1908 Application filed April 17, 1905. .Serial No. 255,863.
To all whomtt may concern:
Be-it known that I,
WORTH, of Morgantown, Monongalia county,
-sect1on; and
designed to increase tion andat thesame time improve the action Y of the grlnding or polishing surfaces upon the West Virginia, have invented a new and useful Apparatus for Grinding and Polishing 'Glass, of which the following is a full, clear,
application.
. My invention relates to the' class of grinding 1 machines for plate glass, and is and'polishi mg the speed of the operaglass. Y
It consists in a novel construction of the polishing blocks or shoes.
-'a disk-bearing which gives the disk a free' socket joint.
{fishing disk 5' as connected to its stem 6 by ball'j'and socket joint 7. by the undercut flange also: rovided for the disk which surrounds I haveimproved the polishing disks by the use of a ball and socket joint between the polshlng disk and its stem in combination with rotation and independent of the ball and Thus in Fig. 2 I show the pol- A be'aring8 formed 8 of its hub or boss is the ball ,joint and supports the disk so that the diskrotates on this bearing while the ball joint allows universal adjustment. The advantage'oflthis feature lies in giving free rota tion while the table is rotating. Where the ball and socket joint alone is used the disk is liable to bind un'derthe pushing action of the table-{but by combining the ball and socket joint with an independentbearingl obtain free rotation of the disk, while at the same FRANK L. O. WApa' a partial top plan showing thetime the disk can adjust itself to the table. The two half boxes 7 for the disk bearing are clamped together by the bolts 7 edge to edge, their lower ends loosely engaging the hub of the disk.
The felt or cloth 9 is secured to the polish ing disk 5 in the following manner: In; stead of using a plain edge on the disk around which the felt is secured, I cut notches 10 in the edge of the disk as shown, these notches being shaped to receive the corner portions 9 of the felt, and being preferably of slightly less depth than the thickness of the felt so that as theconfining ring 11 is forced up over the. disk it will bear only against the corner portions of the felt and force them into the notches. This affords a positive seating of the felt, which-prevents its turning around the disk and it also economizes space'and gives a larger effective polishing area than heretofore. 7
Many changes may be made in the form and arrangement of the various parts wlthout departing from my invention.
I claim:
1. In a machine for grinding and polishing glass, a stem or carrier, and a free non-driven grinding disk or wheel connected thereto by two concentric joints, one of which affords a rotating connection with the stern and the other a rocking or tilting connection therewith; substantially as described.
2. A polishing disk having notched edges arranged'to receive integral upturned corner I portions of the felt; substantially as described.
3. A polishing disk having notched edges f and felt secured thereto by a ring, integral upturned corner portions of the elt fitting Within the notches; substantially as described.
In testimony whereof, I have hereunto set my hand.
