GRINDING-MILL.
5* St'ate' of Ohio,ha've invented new and useful -'Im '-provements in iGrinding-Mills, of which the following is a I specification.
This invention relates to grinding machines, particularly designed for grinding glass or other ware.
An object of the invention is to provide a" machine expressly adapted for use in grinding lantern globes, in which the grinding' element is rapidy rotated in one direction, while thesaid globes are rotated in .a'n' opposite direction at a lesser speed, meajnsb'eing provided for resiliently hold- \ing'the'globe in, contact with the grindin "element for automatically lifting the sai fglob'e from suchcontact after the grinding operation has taken place. Another object is to provide means for ttensioning the resilient holding means, so 'fas tofobtain the proper pressure upon the grinding elementin order to obtain the best esults.
A further object is to provide a. novel 1 form ,of securing arm and means for adjusting the same so as to accommodate articles ofvarious heights, means also being provided for holding articles of different sizes,. which adapts the machine to a wide "latitude of uses.
' A still further object is to provide means for adjusting a globe holding means with "respect to j t provide for the wear of said element, per- 1 mitting the use of the same until the grinding element is entirely worn out.
Still.- anotherobject is to provide means I carried bythe rotatable globe holding means for supplying a grinding fluid to the grinding element, said means insuring a complete distribution of the said grinding fluid over the, surface, of the grinding element.
Other objects and advantages of the in- ,vention will appear as the following description is read in connection with the accompanying drawings, in which I F'g'ureal is a sectional elevation of. a ,grinding machineembodying the present invention; ,"Fig. 2 is a top plan view of the same;
. Specification of Letters Patent.
the grinding element in order Fig. 8 is'an enlarged detailed sectional vlew taken transversely through the grindingrelement and associated parts.
1g. 4 .is a sectional View on the line 4-4 of Fig. 3 looking in the direction of the arrow; and
Fig. 5 is a detailed vertical sectional view illustrating the sliding engagement of the securing arm with the supporting rod.
Fig. 6 is a detailed sectional view showing the manner of holding the lantern globe in position for grinding.
The machine as illustratedin the accompanying drawings is'adapted for grinding lantern globes, although it is obvious that it may be used for various other purposes as will appear from the following description.
In the practical embodiment of the invention illustrated, there is shown. a frame which comprises a base 10, uprights 11 and a horizontal support 12. In this frame is I Patented Apr. 9, 1918. Application filed June 2, 1917. "SerialNo.172,455. l i l journaled a vertical shaft 13, which has rotatably, mounted thereon a disk 14, which is formed or otherwise provided with a hub 15. The lower end of this hub is formed with a ball race, which cooperates with a similar race provided in the support 12 and in which are placed anti-friction balls 16, for the purpose of providing for the ready rotation of the disk 14.
Secured to the outer edge of the disk 14 is a grinding element, in the form of an annulus 17, which is secured to the disk through the medium of bolts 18 or other fastening devices.
The disk 14 is rotated through the mediumof suitable gearing and for this purpose the hub 15 has mounted thereon a spur gear .19, which is adapted to mesh with a similar gear 12 secured to the shaft.
The rods 28 carry brackets 31, which are adapted to be adjustably secured thereon by means of the set screws 32, so as to regulate their height above the disk 27. These brackets carry at their outer ends rings 33, in which are seated detachable cups 34. These cups are provided with seats 35,'whic h in the present instance are formed to accommodate lantern globes, but
-' rest upon the upper surface of the rings Mounted for sliding movement upon the rods 28 are sleeves 37 each of these sleeves carr in an an ularl dis osed su ortin t: t! a arm 38, which is provided at its free end with a rubber or other buffer 39, said buffer being adapted to engage the upper edge of the lantern globe so as to holdit in position within the cup 34. Each of the rods 28 has mounted thereon a tensioning spring 40 one end of which is adapted to bear upon the upper end of the sleeve 37, the opposite end of the spring being engaged by a tension regulating nut 41, which is mounted upon the threaded end 42 of the rod 28. This spring 40 serves to urge the sleeve with its securing arm downwardly so as to keep the buffer 39 in engagement with the lan- "tern globe, and in order to limit the downward movement of this sleeve, the rod 28 is provided with an adjustable stop collar 43, which is split and provided with a set screw and operating handle 44, by means of which it may be conveniently adjusted in position upon the rod 28. In order to prevent the securing arm from rotating about the rod 28, the said rod is provided with a longitudinal groove 43, in which is adapted to slide a guide pin 44 which is carried by the sleeve 37.
Mounted upon the disk 27 is a tank 45, which is adapted to contain a suitable grinding fluid, and thistank has extending therefrom and communicating therewith supply pipes or tubes 46, each of these tubes terminating and extending over the annulus 17, so that the grinding fluid is distributed -from the entire surface of the annulus by from the shaft 26, the said gearing inel glingjie a spur gear 47 with a relatively wide face for a purpose hereinafter apparent? The gear 47 engages a pinion 48, which is mounted upon shafts 49 having hearings in the frame of the machine as shown at 50 and 51, the said shaft also having mounted thereon a ,gear 52, which engages a pinion 53 mounted upon the shaft 21. v
In order to allow for wear upon the working face of the grinding element or annulus 17, the shaft is mounted for vertical adjustment, so that the disks 1.4 and 27 may be adjusted With respect to one another in order to bring the holding devices in proper position over the annulus 17. This vertical adjustment is accom lished through the medium of the adjust le step bearing shown in Fig. 1, which includes the bearing block 54 which carries a thrust bearing 55 of an anti-friction type[ The block 54 is vertically adjustable within the seat 56, the adjustment being accomplished through the medium of a wedge 57, which carries at each end a rod 58, which is adjusted in ears 59 in order to hold the wedge in proper position;
The disks 14 and 27 and their contiguous working parts are housed and'movable within a catch pan 60, which is adapted to receive the grinding fluid which is distributed over the annulus 17, the said fluid being directed in an outlet 61 by the inclined bottom 62 of the catch pan. If desired thefluid may be piped so as to return again to the tank 45, or it may be led to a suitable waste pipe through the medium of the pipe 63.
In order to lift the securing arm 38 from engagement with the lantern globes to permit of their removal from and insertioninto the cups 34, each of the sleeves 37 is provided with a roller 64 and located in the path of this roller is a cam flange 65, each end of which inclines downwardly as shown at 66 so as to efi'ect the gradual raising and lowering of the securing arm 38. The cam flange is secured to a suitable supporting frame 67, which is in turn secured to the catch pan 60.
In the; operation of the machine the disk 14 is driven rapidly in one direction through the medium of the gearing before described, While the disk 27 is driven slowly in an opposite direction through its gearing. As the arms 38 are raised through engagement of the rollers 64, with the flange 65, the
globes are placed within the cups 34, the lowering of the arms 38 causing the engagement of the bufi'ers 39 below, so that they are carried slowly around over the annulus, which is rapidly revolving beneath its them in an opposite direction. The slow movement of the disk 27 permits of the ready removal and insertion of the globes While the machine is in operation.
By providing the radially adjusting slots 29 in the disk 27 the holding devices may be adjusted transversely with respect to the annulus so that its surface may be evenly Worn.- If desired the said holding devices may be adjusted in staggered relation to facilitate this even Wearing of the annulus.
Various changes in the form, proportion and minor details of construction '-may be made as will fall within the scope of the appended claims, and the right is reserved to make such changes. I
Having described the invention, what is claimed is:
1. A grinding machine comprising a'rotatable grinding element, a rotatably mounted disk, holding devices supported upon said disk for movement over said grinding element, said holding devices each comprising a suppoi'tingi-od, a cup independently adjustable upon said rod and a resiliently moiunted securing arm also carried by said ro v 2.
