EDMUND B. BALL, OF BUFFALO, NEW YORK.`
GRINDING-MACHINE..
SPECIFICATION forming part of Letters Patent No. 387,482, dated August 7, 1888.
Application filed September 20, 1887. Serial No. 250,226. (No model.)
To @ZZ whom it may concern:
Be it known that I, EDMUND B. BALL, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, haveinvented certain new and useful Improvements in Grinding-Machines for Glassware; and I do hereby declare the following to be a full, clear, and exact description of the invent1on, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification. My invention relates to apparatus for grindlng glassware especially adapted for fruit or other jars; and it consists in a certain novel combination and arrangement of parts by means of which the weights which hold the jars down upon the grinding-surface are automatically manipulated.
I will now proceed to describe the manner in which I propose to carry out my invention.
In the drawings, Figure 1 is an elevation, and Fig. 2is a top plan View, of my improved apparatus. Figs. 3 and 4 are detached detail Views.
Referring to the drawings, a a are the uprights and a the cross-piece, which form the framework.
bis ashaft, to the upper end of which is keyed the pulley b', over which passes the driving-belt b2, which furnishes the power. The pointed lower end of the shaft b rests in the socket b3.
c is a flat metallic disk rigidly secured to the shaft b and revolving with it. The upper surface of this disk c is the surface upon which the grinding is done.
d is a hopper for the reception of sand,which is fed therefrom through spout d upon the disk c to facilitate the grinding of the jars.
Upon the shaft b below the pulley b is the small gear-wheel @,which intermeshes with the large gear-wheel e', mounted upon the shaft e2, secured to the cross-piece a. Upon the shaft e2 is the small gear-wheel e3, which in turn intermcshes with the large gear wheel e4, mounted upon the long shaft e, secured in bearings e6 upon the side of the cross-piece a. The shaft e5 has rigidly secured thereto the npper rack, f, for carrying the weights and holdi with a series of openings, f2, (see Fig. 3,) 6o
adapted for the reception of the rough mouths of the jars m to be ground.
The mechanism substantially as just described is of old and Well-known construction, and the weights and holders h and k are to be lifted by hand to insert or remove the jars in the operation of grinding. I propose to arrange a novel construction of parts by means of which the weights and holders are automatically raised and lowered, making it necessary to handlethe jars alone. To effect this, Ihave secured to the side upright a stiff metallic bar, n, which has a curved inner end corresponding to the circumference of the rack f and adjacent thereto. The bar n has the long upwardly inclined plane n', with its eXtreme inner end curved abruptly downward, as at n2. The weights h, as they strike the inclined planen', rise gradually until they 'reach the downwardlycurved end n2, when they fall to their normal position upon the rack. To overcome the friction upon the incline, I have so arranged the weights that they revolve with respect to their own axes while on the incline and remain stationary during the rest of their travel. In explanation, it will be seen by referring to Fig. 3 that the rack f is provided with a series of circular inclinedseats, upon which the socketed weights h rest loosely when in their normal position, as seen in Fig. 3.
The seats f3 have side ribs, f4, which rest in A grooves f5 when the Weights rest upon their seats, thus preventing the weights and their holders .7c from revolving while holding jars down upon the grinding-surface c. When the weights 7L are lifted off the seats as they are traveling up the incline n', they are free to revolve, thus materially reducing the friction.
The rod g, to which the weights and holders are attached, is removably and adj ustably secured thereto by the set-screws g and g2, by means of which they can be removed and the IOC holders can be adjusted up or down for jars of different heights.
The operation of niy improved apparatus is as follows: The polishing-disk c and racks f and f being set in motion by the mechanism described, the weights h, and with them the holders 7a as they reach the incline, are successivelylifted and then dropped again as they pass down the curved end a, thus enabling the operator to take out thej ars already grou nd and substitute fresh ones to be ground without necessitating the manipulation of anything but the jars. As the weights rise from their seats f upon the rack f, they are free to revolve, as already described.
l. The combination, with the grinding-ma chine having the revolving grinding-disk c, the revolving raekj" for the jars, and therevolvng raekf, having seatsffand carrying the series of movable Weights 7a, and holders k, of the rod n, having the long curved incline a' and the curved endif, substantially as and for the purpose stated.
2. In a grindinglnachine for glass jars, die., the combination, with the inclines a ai, of the raekf, on which are the seatsf, the Weights h, and holders k, the weights 7L being provided with grooves f to receive the ribs f of the seatsf, substantially as and for the purpose stated.
In testimony whereof I have signed my naine to this specification in the presence of two subscribin g witnesses.
EDMUND B. BALL.
