Application filed February 21, 1921. Serial No. 446,812.
T o all whom it concern." Be it known that T, CLAUDE H. SANDFOR1 I a citizen of the United States, and aresident of Fayetteville, in the county-of Washington and State of Arkansas, have invented a new and useful-Improvement in Cylinder- Polishing, Tools, of which the following is a full, clear, and exact description.
My invention relates to improvements in cylinder polishing tools, and it consists in the combinations, constructions and arrangements herein described and claimed. 7
An object. of my invention is\ to provide a device of the character described in which an abrasive agent is maintained in operative contact with the inner wall of a cylindrical member.
A further object of my invention is to provide a device for polishing and grinding cylinders in which a rotatable substantially ring shaped member carrying an abradant on its outer wall is rotatably supported Within a cylinder in constant engagement with the inner wall of the cylinder to occasion the abrading of the inner wall as required.
A further object of my invention is to i provide a device of the type described in which the abrasive agent may be replaced at will.
A further object of my invention is to provide a device of the type described in which means is provided for successively rotatably supporting substantially ring shaped abradant carrying members of varying sizes.
A further object of my invention isto provide in a device of the type described an abradant carrying member having the form i of an annulus. slitted fromend to end and tapering "uniformly toward its transverse edges.
Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularl pointed out in the appended claims.
y invention is illustrated in the accoinpanying drawings, forming part of this application, in which Fig. l'is a central vertical sectionshowing the use and application of the device,
Fig. 2 is a section along the line 2-2 of ig. 3 is a section along the line 33 of Fig. 2, g Y I Fig. i is a section along. the line 4 -4 of Fig. 2. v 1 in carrying out my invention, I provide a spindle or shank 1 that is for-med at one end thereof for engagement with a drill press or other driving device. The spindle 1 is fashioned with a longitudinally extending groove 2 adjacent its other end which is beveled at 3. A collar 4 is mounted on the grooved end portion of the spindle 1 and is maintained in adjusted position thereon by a set screw 5 having its shank. projected through a threaded opening in an embossed portion 6 into-the slot 2 and by the engagement of the beveled end portion?) with a beveled annular shoulder 7 that extends inwardly from the inner wall of the collar 4: at its-lower end. I
The collar 4 is fashioned to provide diametrically opposed bosses 88 each provided with a radially extending recess or socket 99. Similar retaining pins 1010 have their inner end portions disposed in the sockets 9-9 and their outer end portions projected intov alined openings 11--11 in, diametrically opposed bosses 12-12, that are integral with an abradant carrying member 13, and extend radially through the walls of the latter.
Various parts of the device, the operation thereof maybe readily understood. A suitable abradant, such as an abrasive cloth 17 has an end portion thereof projected between wall of the abradant carrying member along the edge 15 and is maintained in adjusted position by a clamping member 18 that is secured to the abradant carrying member by screws 19. The abrasive cloth'17 is then passed around the outer Wall of the abradant carrying member and its other end portion The bosses 12-12 are positioned. adjacent to one end of the abradant carrythe edges 14 and 15 to lie against the inner tucked within the latter between the contiguous, portion of the abrasive cloth 17 to polish the same.
abradant carrying'member 13 is placed 1n and the edgelft, as clearly shown in Fig. 2.
The device is intended to be used in a machine such as a drill or .a lathe and for the purpose of abrading the inner wall of a cylinderto remove tool marks therefrom or The spindle 1 bearing the operative engagement with a suitable driving machine (not shown) and relatlvely arranged with a cylinder 20, as illustrated.
Rotation of the spindle 1 will occasion a like movement of the abradant carrying member 13 andthe inner wall of the cylinder may 1 be ground to the extent required or polished as desired. In service, the abrasive cloth 17 is covered with a coat of cup grease or the like to insure a satisfactory continued grinding contact of the abrasive cloth with the wall of the cylinder until the former has be-.
come worn to such an extent as to be unserviceable. The device may be rendered suitable for use with cylinders of varying sizes by inserting a padding (not shown) be-. tween the abrasive sockets 13 and'the-ab'ra dant carrying member.
' stood that the spindle 1 may be moved longitudinally during the operation of the device so that the inner wall of the cylinder 20' will; be treated :uniforml for its-" entire length. It is also to be un e'rstoodthat the abradant carrying member 13 is made of a material having inherent' spring qualities and that the same will be slightly com ressed when inserted within-a cylinder so t at the tendency of the edges 14 and 15 to spring apart maintains the abrasive cloth carried on'the outer wall *of the abradant carrying 4 the inner wallof a cylinder. As previously member in constant operative contact with stated, inorder, to adapt the tool to cylinders having bores varying slightly in diameter ders of each size.
. or having oversized bores, or to increase the expansive pressure on theabrasivecloth, a padding member, such as' sheets of paper having the "required thicknessmay be placed around the 'afbradan't-carrying member underneath the abradant cloth. In order -to adapt the-device to. cylinders varying considerably in diameter, a separate abradant' carrying member13 may be. provided for the cylin hese several abradant carrying members 13 will vary onlyin diameter and ay be interchangeably embodied in the'devic v Since .theabradant carrying member varies in thickness from 16 to the-edges. l4
- and 15, it-is in effect an eccentric and"on account of its spring qualities, a close pres, sure fit with the inner wall of a'cylinder is! insured 'llhe abrasive cloth 17 is arranged relative to the abradant carrying member 1 in the embodiment of the invention illusconnection -wit It will be undertrated for rotation in a clockwise direction,
but obviously may be relatively arranged for rotation in either direction.
being normally se arated by the spring action of the annu us, a flexible abrasive member removably secured to said abradant carrying member to cover the outer wall thereof andheld in constant operative contact with the inner wallof a cylinder by the spring annulus. Y
2. A device of the character described comprising a spindle adaptedfor operative'con nection with a driving mechanism, a. collar mounted on said spindle and arranged to turn therewith, said coll-1r having a pair of oppositely disposed bosses on the surface thereof, each of said bosses being proyided with a radially extendingsocket therein, an
abradant carrying member having the fcrm of an annulus slittedfrom endtogend, said abradant carrying member being" provided with openings through the walls thereof in registration with the sockets in said bosses,
and pins adapted to beremovably disposed in saidopenings and to extend into said socket to occasion the mounting of said abradant carryingmember on saidcollar.
3. A device of the character described com--.
prising a spindle adapted for operative con nection with a driving mechanism, a'collar mounted on said spindle and arranged to.
turn therewith, said collar'having a-pair of oppositely disposed bosses on .the' surface thereof, eachof said bosses being provided.
with a radially extending socket therein, an abradant carryingmember being formed of a material having inherent spring qualities and having the form of an open annulus tapering uniformly in opposite directions froma line intermediate its circumference to the opposite edges thereof, said edges being normally separated by a spring action of the annulus, said abradant carrying mem ber beingprovided with openings through the walls thereof in registration with the sockets in said bosses, and pins adapted to be removably disposed in said openings'and to extend into said, sockets to occasion the mounting of said abradant carrying memberson said collar. v
