HARRY KaGOE/YNS, SR., 0F VANDERGRIFT, PENNSYLVANIA.
roLrsHNG AND eamnme 'nEvIcE ron nous..
l'o all whom 'it 11mg concern.
Be it knownffihat l, HARRY K. COLLINS, Sr., a citizen of the United States vof America, residing at of Westmoreland vania, have invented certain new and useful Improvements in Polishing and Grinding Devices for Rolls, of which the following is a specification, reference being had therein to the accompanying drawing.
This invention relates grinding device for rolls, and the prima-ry my invention is to furnish roll housings with positive and reliable means, as hereinafter lset, forth, for expeditiously and economically rinding and polishing rolls without interl eriug with the use and operationof saidro'llsvand the purposes for which they are employed.
Another object of this invention is to provide a roll olishing and grinding device that ,can se advantageously used in connection with rolls 'of sheet and tin plate mills, where the rolls require considerable attention on account of scale and foreign matter accumulating thereon that is detrimental to theprodu'ction of a high grade product.
A further furnishwoll housings with a novel feeding movin a piece of cleansing or abrasive material ongitudinally ofthe periphery operation, the feeding mechanism bein positioned so as not to interfere with the ro ling of metal.
. A still further object of this invention is to accomplish the above results by a mechanical construction that is simple, durable, ine,x" ensive to manufacture, easyto install, and ,highly efficient in connection with various .types ofi'olls.
With the above and other objects in view the invention resides in a novel construction, colmbination and arrangement of parts to be hereinafter specifically described and then claimed..
Reference will now be had to the drawings, wherein f Y Figure 1 is a vertical sectional view of the device in connection with a roll housing, Fig. 2 is a plan of the same partly broken away, Fig. 3 isa perspective view of a detached device, Fig. 4 is a plan of the same partly broken' away, Fig. 5 is a similar view of a. portion of the device as applied to a Specification of Letters Patent.
Vandergrift, in the county y and State of Pennsyl to a 'polishing and l A vertical slots 'Object of this invention is to 'entire lengt-h of the 'angle of the roll while the same is in housing, Fig. 6 is a front elevation of a portion of the device, and Fig. 7 is "aplan of the same.
Further describing my invention .in de tail with reference to the accompanying Patented Feb. 1.0. v1914.. Application led February 10, 1913. Serial No. 647,446. '5
drawings, wherein like numerals denotecorresponding parts throughout:
l 'denotes housings of the ordinary Yand well type that adjustably support revohrbl l"` 2 and 3 forming a pass' 4 for; metal, as plate. 'The housin '1 'are 'provi ied-.'v Y
5'an `lairan'ged in sai are spacer blocks' 6, liners 7 and 'tras supports 8.
catchers riggin cleats 11 provi The, transverse supports S'are employed *for holding a fore-"late 9 anda 10, both of w 'lich rest-up-on A n ed therefor upon the 'in'nerf" f and, confronting faces of the housings,"1'.Vv The fore-plate 9 permits of a sh'eetof n'ietal',A
being extended into the pass 4 rto be 'operg4 r ated upon lby the roll 2 and` the catcherjs rigging 10 4guides the rolled piece offmaterial' i to an operator whereby n y over the roll 2 to again pass betweenthe rolls. Y
it an, been-fad ge 12 denotes an angle plate'piovjdedwithh' a longitudinal slot 13' and an angulaiy iid disposed` ledge or of the angle plate are provided witiifberings 15 for .a longitudinal has an end thereof provided with ar beveled;
gear Wheel 17 meshing `the screw 16` which extends through said block. ,The block 22 has a depending tonguey 23 extending into theslot 13 and the bottom of said block has grooves 24 to receive longitudinal guide ribs 25, carried by the angle plate 12." In consequence of this arrangement the block 22is moved longitudinally of the angle plate when the screw 16 is revolved.
26 denotes holders secured to the block 22 and arranged in said holders is a piece of abrasive grinding and polishing 'material 27, for instance, emery stone,
The ends of the angle plate 12 are pro# vided with extensions 28 and 29 that exwith a similar wheelv 18 mounted upon a rotatable shaft 19 jour tend into the slots 5 of the housings 1. The extension 28 is permanent and the extension 29 is shiftable in order that the angle late 12 can be easily placed between said ousings. The shiftable extension 29 is held in brackets 30 and 31 carried bythe bottom of the angle plate 12 and this particular extension has a flat spring 32 that engages the bracket 31 and locks the extension 29 in a shifted position. v
33 denotes an inclined deflector casing that is located upon the angle plate 12 to extend in proximity to one of the rolls, and the deflector casing associated with the roll 2 serves to guide a piece of metal as it passes back over the roll.
34 denotes pivoted levers carried by the. confronting sides of 'the' housings and operable against racks 35 that hold said levers. in adjusted position. The levers 34 are provided with coiled compression springs 36 that bear against the wall 20 of theangle plate 12 and by shifting said levers the teny sion of the springs 36 can be increased or decreased. The sprin s 36 are employed for holding-the angle p ates whereby the abrasive material 27 will frictionally engage the peripheries of the rolls 2 and 3. This is accomplished by having the extensions 28 and 29 loosely fitting in the slots 5.
As the rolls 2l and 3 are rrevolved the abrasive material 27 removes scale and foreign matter from the peripheries of said rolls and the removed matter is collected by the tray 14 on the device on the roll 2, while it is not necessary to use a tray lin connection with the device of the roll 3. The tray 14. assoeiated withl the roll 2 prevents foreign matter from collecting upon'the foreplate. It is thought that the manner of moving the abrasive material longitudinally of th'erolls will be apparent Without further description and while in the drawings housings, rolls journaled in said housings,
an angle plate adjustably supported between said housings, a tray carried by said plate,-
a block movable longitudinally of said plate,
abrasive material carried by said block, a deflector arranged upon said plate, andV means carried by said plate for moving said block longitudinally of said plate.
2. In a roll grinding and polishing device, housings, rolls journaled in said hous ings, an angle plate adjustably supported between said housings, a tray carried by said plate, a block movable longitudinally of said plate, abrasive material carried by said block, a deilector arranged upon said plate, means carried by said plate for moving said block longitudinally of said plate, and means carried by said housings and engaging said plate for holding the abrasive material thereof in engagement with a roll. In testimony. whereof aflix my signature in the presence of two Witnesses.
