PETER DOSCH AND CHARLES DOSCH, F STRATFORD, CONNECTICUT.
DISK-GRINDING MACHINE.
Be it known that we, PETER DosoH and CHARLES R. DosoH, b'oth citizens of the United States, residing at the town of Strat- An important object resides in the novel mounting of the diskon the motor shaft whereby the former is easily removable from the shaft and is adaptedto .be firmly attached without interrupting the abrading surface as by screws or bolts employed in attaching the disk.
A further object is to provide a dust collector which will ofthe grinding disk and also constitute a support for the work table.
and claimed, reference Another aim resides in mounting or supporting the work table so that it may be swung or adjusted vertically with its inner edge always close to the grinding disk.
Theinvention further resides in the features of constructi on, arrangements and combinations of parts hereinafter described being had to the accompanying drawings wherein:
Figure 1 shows the preferred form of the invention in top plan; Fig; 2 illustrates the same in front eleva tion; Fig. 3 is a side elevation of the machine showing in dotted line an adjustment which the table is capable of making; Fig. 4 is a vertical section through the dust collector taken along line 4-4 of Fig. 3; Fig. 5 is a vertical section through the grinding disk and its mounting; and Fig. 6 is a rear view of the cheek plate to which the grinding disk is attached.
Referring more in detail to the drawings, the dust collector 1 is suspended from the base 2v of a motor 3 which latter is preferably electrical.
The shaft 4 of the motor has fixed to one end the hub 5 of'a cheek plate 6 which latter is formed with a concentric series of key-hole-shaped openings each consisting of Specification of Letters Patent.
to that type of mahouse the lower portion Patented Aug. 8, mile.
Application filed January 26, 1916. Serial No. 74,327.
- an entrance or escape portion 7 and a restricted slotportion 8.
The grinding disk 9 has its active face 10, preferably in the form of sand paper or emery cloth, adhesively or otherwise secured thereto, while to the rear face and extending axially therefrom are a series of threaded pins 11 carrying nuts 12. These nuts, which have broad, washer-like,.bearing faces 12,
are of sufficient size trance openings moved into the slots 8 by rotating the disk 9 on the cheek plate 6, to clamp the rear face of the latter to secure the disk to the Plate it;
The'rear fabe of the disk 9 is centrally retopass through the en- .cessed to receive-a hub extension 13 which further aids in supporting and centering the disk.'
Thedust' collector houses the lower portion of the grinding disk and has its opposite sides formed with arcuate channels or recesses 14 in which operate inwardly extending ribs 15 of the similarly shaped brackets 15. These brackets support the 'work table 16 so that the forward edge of the latter is at the center about which the are shaped brackets swing. By this mountmg, the inner edge of the table is always .close to the grinding disk, thedistance being the same throughout all adjustmentsas depicted in Fig. 3.
A clamping rod 17 extends through the collector 1 and hason one end a permanen head or jaw 18 overlying one of the brackets 15. The opposite end of rod 17 is threaded to receive a nut member 19 which bears on a slidable jaw 20 and, when tightened, clamps the jaws 18 and '20 against their respective brackets, as clearly disclosed in Fig. 4. The jaw 20 is conveniently provided with a setting mark adapted to register with the scale on a bracket 15, Fig. 3, whereby the desired inclination of the table may be accurately obtained.
In order to provide ample room to remove the grinding disk, the table is provided with a detachable forward section 21 which is secured in position by a screw 22. By thus removing this table section, sufficient space is provided for the axial movement requisite in removing the disk.
A work guide 23 is pivoted to a block 24 for angular adjustment which is slidable in a transverse groove 25 provided in the table. This enables the operator to take advantage 7 and, when the pins .are,
tar
table adjustably supported on the collector and covering the latter.
7 2, In a grinding machine, a grinding disk, a dust collector arranged therebeneath and partly receiving the disk, a work table,
.and arc-shaped brackets adjustably supporting the table from and above the collector to constitute a guard and closure for the latter. I
3. In a grinding machine, a grinding disk, a dust collector arranged ther'ebeneath and having its opposite sides provided with arcuate channels, a. ,work table, and arcuate brackets adjustably engaged in the channels of the collector for supporting the table.
-'L. In a grinding machine, a grinding disk, a dust collector arranged therebeneath and having its opposite sides provided with arcuate channels, a work table, arcuate brackets slidable in the channels of the collector and supporting the table, and clamp means carried by the collector for engaging with and adjustably securing the brackets.
5. In a grinding machine, a grinding disk, a dust collector arranged therebeneath and partly receiving the disk, said collector having its opposite sides between which the disk is disposed provided with arcuate channels, a work table, arcuate brackets slidable in the channels of the collector and supp'orting the table with its forward edge subgrinding surface at any' port, a grinding the table for arcuate stantially at a fixed point above the dust collector to always overlie the latter.
6. In a grinding machine, a rotatable supdisk thereon, removable by axial movement, and a sectional Work table arranged across and adjacent to the disk and having that section nearer the disk movable from an operative position to provide ample room for the removal of the disk.
7. In a grinding? machine, a rotatable support, a grinding disk removably secured thereto, a work table, means for supporting movement transversely of the disk, and a forward removable section of the table'adjacent the disk, whereby on the removal of said section space is provided for the removal of the disk, said meanssupporting the table so that the edge of the forward removable section, when the latter is in an operative position, is substantially in a fixed point.
8. A grinding machine comprising an abrading element, a motor for rotating the element, abase plate supporting the motor and extending forwardly thereof, an elongated transversely arranged dust collector carried at the forward edge of the base plate and depending therefrom, the opposite ends of the collectior being formed with.
curved seats, a work table, brackets engaged in the seats of the collector and supporting. the table, and a clamplng device arranged on the collector adjacent aseat thereof to impinge on the adjacent bracket to hold the table fixed.
Intestimony whereof we afiix our signatures in presence of two witnesses.
