This invention relates to scale removers, and while not limited thereto, 'relates more particularly to scale -removers especially adapted to remove the scale from forged wheel blanks and the like.
One object of the present invention is toi provide a scale remover which will effectively remove the scale from forged wheel blanksv and the like, quickly andl withy the expenditure of -a minimum of labor.
Another object is to provide a scale remover vhaving the novel construction, design and combination of parts hereinafter dev scribed and illustrated in the accompanying drawings.
' In the drawings;
Figure j 1 is a vertical sectional view through a scale' removing apparatus embodying our invention. 29 'Figure 2 is a horizontal sectional view on the line II-II of Figure 1.
Figure 3 is a sectional view on the line III-III- of Figure 1.
Figures 4 and 5 lare. enlarged sectional details of the operating shafts and striking chains.v
Figure 6 is'a plan and Figure is a side elevation of the work-support.
Referring more particularly to the drawings, the numeral 2 designates the casing of the apparatus which is'rnounted in a base 3 which is cut away .as a't 4 to permit the escape of the scale into a pit or bin, not shown. Two pairs of shafts 5 and 6, and 7 and -8 are journaled in vertically spaced relation in bearings 9 in the casing2. The shafts 5, 6, 7 and 8 have removable end portions or trunnions 10 which are' bolted to the main portion of the shafts so as to 'provide for ready removal of the main portions of the shafts.
The shafts 5, 6, 7and,8 are provided with gears 14, .15, 16 and 17, respectively, all of which are intermeshed so that all the Shafts .must rotate together and at the Same speed A motor 18 .is provided for driving the shafts 5, `.6, 7 and 8 and has its armature shaft 19 provi/ded with a pinion 20 which is in mesh with the gear 16 on the shaft 7. .50
site rows of spaced vrs or depressions 21, .and a plurality of cham retaining rin 22 are mounted on each of the shafts and spacer rings 23.
v bla held in alinement with the recesses 21 by chains 24 are secured on the rings 22 so that their upper links enter the recesses or depressions 21. The recesses 21 serve to permit the chains to move or swing relative to the rings 22 and also serve to hold the chains in spaced relation on the shafts 5, 6, 7 and 8.
A plurality of strikerY A plurality of-angle pieces 25 are Secured i along ,one side of the casing 2v and extend into the path of the work-piece. The wheel blank or work-piece designated by the letter A is'adapted to be supported by and moved into and out of the scale removing apparatus by the eel 26 of a charging machine (not shown The charging machine is part of the standard mill equipment.
The base plate 3 of the casing 2 extendsv a material distance beyond the forward end of the casing and is provided with a roller support'27 for supporting the peel 26 as it is .extended to enter the casing 2.
The peel 26 has its forward end or workpiece supporting member 28 removable so forms of work-piece supporting members.
-The work-Supporting member 28 is provided with a4 forked forward end 29 adapted to fit around the hub portion B' of the wheel blank A, s o as to form a secure mountin and bearing for the wheel blank.
n operation the work-piece or wheel blank A is positioned on the'peel 26,and the motor 18 is started to rotate the shafts 5, 6, 7 and 8 thereby whirling the chains 24.l The peel 26 is then moved forward to move the work-piece into the nath, of the chains 24 which strike the blank A and break oi the scale. As the blankA moves into thecasing pieces 25 and cause the lank to rotate on as to provide for thev attachment of different j the l thereby exposing the parts of the 4resting on the peel to the action of the striking chains 24. The peel 26 may be withdrawn and inserted a number of times dring the scale removing operation to cause a more extensive rotation of the blank, if Each of the shafts 5, 6, 7 and 8 is prov1d ed with a plurality of diametrically oppo' desired.
While we have shown and described one specific embodiment of 'our invention, it gs` will be understood that we do not wish to be limited thereto, Since various modifications i when said shafts are rotated, and a recipstriking elements.
rocatory work-piece support adapted to l move the work-piece into the space between said vertically spaced shafts so as to permit said-striking elements to strike against the upper and lower faces of the work-piece.
2.`A scale removing mechanism comprisingLin combination, a plurality of flexible striking elements adapted to strike and remove the scale from a work-piece, and a movable work-piece support adapted to move the work-piece into position to be struck by said striking elements.
3. A scale removing mechanism comprising, in combination, a plurality of flexible striking elements adapted to strike and remove the scale from a work-piece, and a reciprocatory work-piece support adapted to move the vwork-piece into position to be struck by said striking. elements.
y 4. A scale removing mechanism comprisi11g in combination, a plurality of centrifugally operated flexible striking elements adapted to strike `and remove' the scale from y a workipiece, and a movable work-piece sup,- port adapted to move the work-piece into the path'of said striking elements.
5. A scale removing mechanism comprising, in combination, a casing, a plurality of shafts journaled in said casing, means for 'rotating said shafts, a plurality of flexible striking elements on each of said shafts, and a work-piece support for 'supportingthe work-piece in position to be struck by said 6. A scale removing mechanism comprising, in combination, a casing, a plurality of l. shafts journaled in said casing, means for rotating said shafts, a plurality of ex1ble 'rotating said shafts,
Leonesa striking elements secured' to each of said shafts and adapted to haveI a centrifugal motion imparted thereto when said shafts are rotated, and a reciprocatory work-piece support adapted to move the work-piece into the path of said striking elements.
7. A scale Vremoving mechanism compris` ing, in combination, a casing, a plurality of shafts journaled in said casing, means for a plurality of striking elements on each of said shafts, a workpiece support for supporting the work-piece in positlon to be struck by said striking'elements, and means forlrotating the workpiece on said work-piece support.
8. A scale' removing mechanism for removing scale from wheel blanks comprising, in combination, a casing, a plurality of shafts journaled in said casing and spaced vertically, means for rotating said shafts, a plurality of striking chains secured to each of said shafts and adapted to have a centrifugal motion imparted thereto when said shafts are rotated, a reciprocatory workpiece support adapted to support and move the wheel into the path of said centrifugally moving chains so that said chains will strike and remove the scale from the surface :if the wheel, and means in said casing adapted to engage and rotate the wheel on said worksupport.
9. A scale removing mechanism comprising, in combination a casing, a ,lurality of vertically spaced shafts journa ed in said casing, means for rotating said shafts, a plurality of flexible striking elements secured to each of said shafts and adapted to have a centrifugal motion imparted thereto when said shafts are rotated, a reciprocatory work-piece support adapted to rotatably support and move the work-piece into the space between said vertically spaced shafts so Aas to permit said striking elements to strike against the upper and lower faces of the work-piece, and means for rotating the work-piece on said work-piece support.
In testimony whereof, we have hereunto set our hands.
