MACHINE FOR GRINDING THE RIMS OF GLASS VESSELS.
' Application filed June 8,
To all 1N1 0m it may concern:
Be it known that l. Mariner: Mom, a subject of the King of Belgium, residing at Flemallc-(lram'te. Belgium. 28 line Leopold, have invented certain new and useful Improvements in Machinesfor Grinding tho Rims of Glass Vessels: and I do hereby declare the following to be a full, clear, and exact description of the invention, 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 therein, which form apart of this specification.
The present invention relates to a machine for grinding the upper rim of glasses, cups and other glass vessels so as to polish said upper rim and at the same time to cut and straighten the same in such a manner that its plane is' exactly parallel to the base plane of the vessel and that all the vesscls-of set are shaped to the same height. v The machines used for this purpose comprise generally a rotary grindstoneirotating on a vertical shaft and supplying water to the glass to be ground by means of a duct providedin the axis of A fi rimlstone. In these machines. the vessel to be ground is secured to a holder adapted as to force the glass vessel against the grindstone. Such a device has disadvantages because the movable partsuscd for performing the vertical motion of'thc glass. being arranged under said glass, are damaged in a short time by the action of water and abra'ding powder flowing down from the glass.
These inconveniences are avoided in the macl'iine according to the present invention, by the fact that thevessel to be ground remains quite motionless While the grindstone is allowed to move vertically during the operation so as to be brought into contact with the vessel. The invention also consists in means for adjusting the pressure exerted upon the glass by the grindstone. and for limiting the vertical movement of the grindstone according to the height of the glass.
Means are also provided for supplying Specification of Iietters Patent.
the shaft and of the Patented Sept. 25, 1917. 1915. Serial no. 32.877.
water to all the parts of the operating face of the grindstone.
Figure l is a side view of a first form of the invention.-
Fig. 2 is a similar view of a second form of the invention.-
Fig. 3 is a partial vertical sectionyon'an enlarged scale, in this second form.
' The machine according to Fig. 1 comprises a vertical rotary shaft 1 fixed to the grindstorte 2 and journaled in frame 4 and in a movable sleeve The shaft 1 is driven by an electric motor 6, by means of a belt and pulley 7; it can slide freely in the bea of a shoulder upon the sleeve 5. Said sleeve ring 3 and rests by. means a bearing 3 of the frame 4 at any desired height, by means of" a screw 48: the sleeve 5 is provided with a rack 9 in gear with a pinion 10 thatcan be operated by .a lever ]1 in such as -manner 'as to cause a vertical movement of the sleeve 5. The weight of the vertically slid ing parts is balanced by a counterweight 12 hanging to a cable 13 secured by its other end to the sleeve 5 and passing over snitahlc pulleys 14.. Upon the lever 11 is'arranged a weight 42. the position of which can be varied at \villjand which causes the lever 11 and at the same time the sleeve 5 to go down. In the shaft 1 and grindstone is bored an axial duct l5-through which a hose 16 attached to the shaft 1 with, the' interposition of a ioint allowing he shaft to rotate treclv. .ecured to a fixed table 19 by any suitable means. i i l Vhen the glass is secured to the table 18. the shaft 1 rotated at the required speed and the water supplied. the "workman, who is I holding the lever 1.1 in the upper position, releases the lever. the weight 42 of Which causes the sleeve 5 to go down and the grindstone 3 to come into contact with the glass 17. stone upon the glass can be varied according to the thickness of the glass by varying theposition of the weight 42 on the lever The-glass to be ground is wire-gauze 47 is fixed to the pipesfia so as to pins 26 pass.
When the glass 17 has been ground out to I shoulders of the shaft, and provided with.
two pins 26. A. lever 27 pivotally mounted at 28 on the frame 23 is so shaped as to form two arms surrounding the sleeve 24 and provided with slots 29 through which the On the lever 27 is also arranged a weight 30, the, position of which can be varied at will. The weight of the movable parts is partially balanced by the power of a spring 31. As a means for limiting the downward movementof the shaft, an iron piece 32 is provided; this piece is bent at a right angle and the horizontal arm is provided with a circular hole through which the shaft 20 passes, while in the vertical arm a longitudinal slotfs made, through which passes a screw-threaded rod 34 fixed to the bearing 22; the piece 32 is secured to the bearing 22 at any desired height by means of a nut 33 crewed on the rod 34. The shaft 20 is powe driven as in the apparatus shown at Fig. *1.
Water is supplied by means of a hose 35 and an annular channel 36 which surrounds the cylindrical part 37 of the carrier of the grindstone 38 and is attached to said cylindrical part by means of tightjoints adapted to permit the carrier 37 to revolve freely. The water supplied to the channel 36 is divided into several currents; a portion of this water passes through ducts 39 and 40 pro vided in the carrier 37 and grindstone 38 and comes in the vessel to be ground. Other portions are sent against the lower face of the grindstone by means of pipes 44.
The ends 45 of these pipes are adapted to turn at it? on the pipes 44 in such a manner that the ets can be directed at will against any desired point of the grindstone.
prevent the water from being thrown about.
The vessel43 is securedto a fixed table 41.
Before beginning to grind a set of glass vessels, the workman arranges the weight-30 in the right position according to the pressure to be exerted on the vessels. and secures the iron piece 32 at the height required. Then he lifts the lever 27, secures the vessel 43 to the table -11, opens the supply of water and releases the lever 27 then the machine performs automatically the work required.
It must be noted that the arrangement of pipes 44, 45 and .46, as described hereinhefore in connection with the device represented in Figs. 2 and 3, can also he applied to the device represented in Fig. 1. In Such a case, the pipes 44 communicate with the axial duct 15 at any suitable point below the sleeve What I claim is:
1. In a machine for grinding the rims of glass vessels, the combination of a vertical shaft, a grindstone attached to the lower end of said shaft, means for counterbalancing the vertical shaft and appendant parts, driving gear for rotating said shaft, means for fixing the glass vessel so that the rim thereof is presented to the grindstone, a pivoted lever operatively connected to said shaft, an adjustable weight on said lever to gravitate the same and impart axial movement to the shaft so that the grindstone thereon engages the rim of the glass vessel with predetermined pressure, and central and radial conduits for conducting water to the cutting surface of the grindstone.
2. In a machine for grinding the rims of glass vessels, the combination of a vertical shaft, a grindstone attached to the lower end of said shaft, means for fixin the glass vessel so that the rim thereof is presented to the grindstone, means for axially displacing the vertical shaft so that the grindstone engages't-he rim of the glass vessel, and a central condpit and adjustable radial conduits for conducting water to the cutting surface of the grindstone.
3. In a machine for grinding the rims of glass vessels, the combination of a vertical shaft, a grindstone attached to the. lower end of said shaft, means for fixing the glass vessel so that the rim thereof is presented to the grindstone, means for axially displacing the vertical shaft so that the grindstone engages the rim of the glass vessel, and a conduit branching, in proximity to the grindstone, into a plurality of central and radial conduits, the latter being adapted to direct the flow of water against the inner face of the grindstone.
In testimony whereof I affix my signature in presence of two witnesses.
