Description
Nov. 26, 1929. R. F.- GIBNEY POLISHING MACHINE Filed Feb. 6. 1925 11v VENTOR TTOR NE Y Patented Nov. 26, 1929 UNITE POLISHING nae-mm Application filed February My invention relates to polishing machine, particularly suitable for the polishing of barrels and caps used in the manufacture of fountain pens and mechanical pencils.
The object of the invention is to provide 5 a machine which is simple in construction, easy to operate and which will permit the polishing of surfaces of varying periphery with a substantial cylindrical buff and which will eliminate ridges or rings that mayv be in the article before it is being polished.
Another object of the invention is to provide a machine that will permit adjustment for the wear of the buff.
A still further object of the invention is to so arrange the holders for the object to be polished that the velocity of the buff tends to force the object on to the holder.
In the appended drawing, Figure 1 is a vertical section through the machine embodying my invention on line 11, Figure 2, an
Figure 2 is a top plan view. 7
Referring to the drawing, 3 is a frame which is preferably in the shape of an angle, the upright portion 4 of which is provided with guide-ways 5 while the horizontal portion 6 thereof has suitable lugs 7 for securing it to a bench. The horizontal portion 6 and the upright portion 4 of the frame 3 are reinforced by ribs 8.
A bed 9 provided with a depending portion 10 is mounted to slide in the guide-ways 5 of the frame 3. The movement of the bed is con trolled by a screw 11 threaded into the frame 3 and connected to a lug 12' of the depending portion 10 of the bed. The depending portion 10 of the bed carries a vertical shaft 12 to which shaft is keyed a rotary table 13. The rotary table 13 carries a beveled gear 14 which is in mesh with a beveled pinion 15. The said pinion is constrained to revolve with a shaft 16 mounted on the bed 9. The shaft 16 also carries a loose pulley 17 provided with a clutch face 18 and a clutch 19 is provided on the shaft which is constrained to rotate with the shaft. A lever 20 mounted on the bed 9 controls the motion of the clutch 19 on the shaft and whereby the loose pulley may be coupled e, 1926." Sierial 'N'o. 86,479.
or uncoupledfrom the said shaft lti. T o re- 2 tain the clutch119 iii-either position suitable means are provided on a lever and abed 9.
The rotary table 13 carries a plurality of posts 21 disposed near the oirterperi'phery of theitable. Each of the postshas a reduced cylindrical portion 22 which engages a cor} responding opening 23in the table. Each of theposts 21 is locked to the bed by means of a screw 2 Seel igiire1 Each ifthe posts also carries an article hold'erjor mandrelj25 fitted into a corresponding'hole"in the post and secured thereto by a screw26 l c As will be seen from Figure 2, thein'andrels in the posts are disposed at an angle to the radial line of the table, and this angle may be varied by means of the said screws 24:. A cylindrical buff 27 shown in Figures-1 and 2 in dots is revolved in a vertical plane in the direction indicated. The mandrels carrying the objects to be polished move toward the buff in the direction as indicated in Figure 2. As shown in Figure 2, the mandrel over the buff in said figure carries a fountain pen barrel indicated in dash and dotted lines. As the buff strikes the barrel, the friction forces the barrel on to the mandrel as it revolves it on the mandrel.
Furthermore the buff engages the barrel on the mandrels obliquely to the axis of the barrel, that is, the axis of the article and the directrix of the cylindrical surface of the buff form an acute angle which decreases in size as the article passes over the buff. In consequence, the resultant force of this acute angle causes the article to move on to the holder. Due to this angular engagement of the article with the buff, the cutting or polishing line on the buff on the article is at an angle to the axis of the article, thereby eliminating ridges in the surface of the article that may have been formed during the grinding or polishing.
As the buff wears, the bed 9 can be lowered by means of the screw 11, thus compensating for wear of the buff. To retain the bed 9 rigid with the frame 3, lock screws 28 are provided in the frame 3 at the guides as shown in dotted lines in Figure 2.
I claim: I 1. In combination a cylindrical buff revolv- V I ing in a vertical plane, a table revolving in a horizontal plane, article holders on said table 5 disposed at an an 1e to the radial line of the table, and means for varying the angle of the holders with the radial line of the table, said holders supportng the articles so that the same are free to revolve thereon and to move 1 outwardly, the articles being prevented from moving outwardly while being rotated by the buff by the angular relation of the holders with the buff at the time of contact of the articles with the buff. 2. In combination a cylindrical bufl' revolving in a verticalplane, a table revolving in a horizontal plane, stationary mandrels disposed in a horizontal plane and carried by said table, and means for adjusting the angu- 2 lar relation of the mandrels with the radial line of the table, said mandrels adapted to support the fountain pen barrels or caps, so that the same are free to revolve or move outwardly thereon, the caps or barrels being prevented from moving outwardly on the mandrels when actuated by the buff, by the an gular relation between the bufl? and the mandrel as the mandrel passes the bufl. I ROBERT F. GIBNEY.
