ABRADING MACHINERY.
To all trim/n Z may concern Be it known that I, BERNARD XAGEIr 'vtmu'r, a citizen of the United States, and resident of Detroit, lYayne county, State of Michigan. have invented certain new and useful Improvements in Abrading Machinery, of which the following is a specification.
' This invention relates to cutting and abrading machinery, and the principal object of the invention is to provide an abrading device with means for collecting the dust produced by that device.
'In the form of the invention shown and described herein, a rotary abrading disk is shown as entirely surrouiuled bv a casing,
which is arranged substantially in the plane of the disk, and the inner side of which is open to receive the cuttings or dust thrown from the periphery of the disk.
Another object of the. invention is to so arrange the dust collecting casing about the abrading disk that it will not in any way interfere with the full working face of the disk. I
' Other objects of the invention will be apparent from the following description. taken in connection with the drawings which form a part ofthis specification. and inwhich, I
Figure 1 1s a perspective new of 'an abrading device embodying the invention:
Fig. 2 is an elevation. and part sectional which tends to view of the dust collecting casing; and Fig. 3. is partly .a front elevation of the casing and disk, and partly a longitudinal section through the casing.
Referring to the drawings, represents an abrading disk of any suitable constructiori, which is mounted in bearings 11 in a frame or support 12 and is driven through belt 13 and pulley 14 from any suitable source'of power.
As is well known, in the use of abrading machines of the above described character, considerable dust is created, which is objectionable to the operator and is llkely to get into the bearings of the machine if it is not properlygathered and d sposed of. The present invention takesadvantage of the centrifugal action of the grinding disk throw the dust directly away from. the periphery of the face of the disk, rovided to entirely surround the disk 10 and collect the Specification of Letters Patent.

cuttings or dust thrown therefrom. The casing lD lS connected to an exhaust pipe 16 from which the air 18 exhausted by anv suitable exhaust mechanism, not shown.
The inner side of the casing is cutaway, as shown particularly in Figs. 2 and 0, and a pair of annular defiector plates 1? v are secured to the inner edges 18, as shown -in said figures.
V These deflector plates are arranged to form a sort of trough, lm-ving their outer edges arranged adjacent each other and leaving a narrow opening or slit 119 between them, and having their inner edges separated or flared for the. purpose of" deflecting the cuttin s or dust which BERNARD NAGELVOORTQOF DETROIT, MICHIGAN, ASSIGNOR T0 PACKARD MOTOR can are thrown from the 'ieriphery of the'disk;
10. being approximately in the plane of the face. of the disk 10, which is probably its most advantageous position for gathering the cuttings and dust. The-.adjacentedges of the deflector plates 17 are tied together by suitable straps 20 secured thereto and arranged at intervals a-round.the plates.
This-makes a more rigid construction and insures the opening or slit 19 being main" tained at a given total area, which total area must be less than the cross sectional area of the interior of the casing 15 where 1t joins the exhaust. pipe and of the exhaust pipe 16. It has been found by repeated eX-- periments that it is of the utmost importance for the success of this machine that this opening 19 be maintained with a less area than the area of the exhaust pipeyas above set forth. It will be noted that the entire casing and deflector plates are entirely outside of the periphery of the disk 10, which permits of the use of the entire working faceof the disk. A work table 21 drawlngs and descrlption, it being obvious "that the dust created in the operation of the disk 10 against the work placed upon the table 21 will be thrown radially from the periphery of the disk 10 and deflected by the plates 17 toward the opening 19. Since air is being exhausted from the pipe 16, and hence from the interior of the casing 15,
The annular opening 19 is shown as there is a strong suction through the openmg 19, which of course will carry with it all of the dust in the immediate vicinity. Thus practically all of the cuttings and dustmany changes may be made without depart- 1 scope of the ining from the spirit and vention I 4 Having thus described my invention, what I claim and desire to secure by Letters Patent is:
1. The combination with an abradi'ng device, of a casing adjacent thereto having an opening to receive cuttings ordust therefrom, and an exhaust pipe connected to said casing, the cross-sectional area of said exhaust pipe being greater than the total area of said opening.
"2. The combination with a rotary abrading wheel, of a casing surrounding the pe riphery of said wheel and having an annular slit or opening partly in the plane of said wheel, and an exhaust pipe. connected to said casing.
3. The combination with a rotary abrading wheel, of a casing surrounding the periphery of said wheel and having an annular slit or opening partly in the plane of said wheel, and an exhaust pipe connected to said casing, the cross-sectional area of said exhaust pipe being greater than I, the
total area of said opening.
4. The combination with a rotary abrading wheel, of a casing surrounding the periphery of said wheel and having a annular slit or opening partly in the lane of said wheel, deflecting means'for irecting casing.
cuttings or dust from, said wheel toward said opening, and an exhaust p pe connected to saidicasmg.
5. The combination with a rotary abrad ing disk, of an annular casing surrounding the periphery of said disk and having its inner side open, annular deflector plates secured to said casing at its inner edges and providing a narrow opening between'their adjacent edges, said opening being approxi mately in a plane with the face of said disk and forming the inlet of said casing, and
the periphery of saiddisk and having its inner side open, annular trough-like deflector plates secured to said casing at its inner edges, said casing and plates being entirely beyond the periphery of said disk, and, an exhaust ipipe connected to said 8. The combination-with a rotary abrading disk, of an annularcasing surroundingthe periphery of said disk, I annular deflector plates secured to said casingv and forming between them an annular opening into the casing in a plane with the face of said disk, and an' exhaust pipe" connected with said casing.
In testimony whereof I aflix my signature in the presence of two witnesses.
