SPECIFICATION forming part of Letters Patent No. 610,433, dated September 6, v1898.

Applicant niet my 18,4 189s.

To @ZZ wiz/0m, it moby concern.-

Be it known that I, CHARLES I-I. CURTIS, a citizen of the United States,residin g at Derby, county of New Haven, State of Connecticut, have invented a new and useful Automatic Bufng-Machine, of which the following is a specification.

My invention has for its object to provide an automatic bufng-machine which shall be adapted to buff all sizes and styles of articles within the capacity of the machine,which will do its work in the finest manner possible, and which shall require the services of but a single attendant in feeding the machine and removing the finished articles.

With these ends in viewI have devised the simple and novel bufngmachine of which the following description, in connection with the accompanying drawings; is a specificafl tion, numbers beingused to designate the several parts.

Figure l is a side elevation; Fig. 2, a front elevation Fig. 3, a plan view, the standards being in section on the line .fr as in Figs. 1 and 2; and Fig. 4 is a detail View, on an enlarged scale, of mechanism Vfor raising each holder in turn into a position in which the article carried thereby may be acted upon by the bufIing-wheel.

1 denotes the bed, 2 legs by which itis supported, and 3 standards extending upward from the bed, said parts comprising the frame! work of the machine.. I Wish it distinctly understood, however, that the special con-V struction of the framework of the machine is not of the essence of my invention, but that the details may be varied to suit the require-V ments of any special use for which the ma chine may be intended or the taste of the builder. u

4 denotes the buffing-wheel, which may be of any ordinary or preferred construction-` for example,` a rag-wheel, so called. 1 The buhingwheel is carried by a shaft 5, jour naledin bearings G upon a vertically-adjustable lcarrier 7. The ends of the carrier engage slots 8 in the standards,and the carrier, and with it the shaft and buftlng-wheel, is adapted to be moved toward or from the feedwheel,` presently to be described, as may be required in use, bymeans of screws 9, carried serial No. 681,036. (No man.)

by across-piece 10, extending from one standard to the other." The screwsare free to be turned in the cross-piece, but are held against vertical movement therein, so that rotation of the screws will raise or lowerthe crosspiece and the buffing-wheel. Power'is applied to the machine by means ofa belt (not shown) passing over a pulley 1l on shaft 5. l2 denotes another pulley on shaft 5, from which a belt (not shown) extendsto a pulley 13 on a shaft 14, journaled in boxes 15, in the present instance under the bed.

16 denotes a pinion on shaft 14., which meshes with a gear wheel 17 on a shaft 1S, journaled in boxes 19, in the present instance under the bed. At the inner end of .shaft 1S is aworm 20, which meshes with a wormwheel 21 on a vertical shaft 22, journaled in a hub 23 on the bed.

, 24denotes a feed-wheel carried by shaft 22, which rotates in a plane .at right angles to the plane-of the bufng-wheel. l

The articles to be buffed are carried by holders 25, each holder being carried by a plunger 26, adapted to engage any o ne of a series of correspondingly-shaped openings 27 in the feed-wheel, in which it is adapted to slide freely. The lower end of each plunger is rounded, as at 28, (see Fig. 4,) to adapt it to engage and be raised by a rounded shoe 29, which lies below the feed-wheel and in the vertical plane of the bufling-wheel. Each holder is provided with a clip or clips 30 to hold the article to be buffed, and as each holder in turn comes under the buffing-wheel it is raised into position, so that the article carried thereby will be acted upon by the bufng-wheel. The instant, however, that .the plunger has passed the shoeit drops down to its normal position, as clearly shown in Fig.4. The shape of the shoe is of course not of the essence of my invention and may be varied to suit the requirements of special articles that are to be buffed. I have shown both ends of the shoe as so shaped as to provide an easy incline for the plunger to ride up and to ride down and have shown the ceuter as slightly depressed. These, however, are mere details of construction and may be varied to suit the special use to which the machine is applied. By making the shoe IOO highest on opposite sides of the center I provide that the holder and the article that is being buffed shall be raised at the instant it passes under the edges of the buflng-Wheel,

so as to receive the full action of the edges of the bufiing-Wheel as Well as of the center. The shoe is provided on its under side With an ear 3l, which is pivoted to a plunger 32, which is adapted to engage a correspondinglyshaped opening 33 in the bed, in which it slides freely. The ends of the shoe may be raised or loweredl to give any required adjustment thereto by means of set-screws 34 in the bed, as clearly shown in Fig. 4. It Will be seen that by providing simple and convenient adjustments for both the bufiing-Wheel and the shoe and by making the holders removable, so that other sets of holders may be substituted, if required, I insure an almost unlimited range of usefulness for the machine in bufing articles of varying shapes and sizes.

Having thus described my invention, I claim-f l. The combination With the bufing-Wheel, of a feed-Wheel, holders on the feed-Wheel for articles to be buifed and means for raising each holder at the instant it passes under the bufng-Wheel, said holders being also removably supported by the feed-Wheel and adapted to be lifted therefrom or replaced during the rotation of said Wheel.

2. The combination With abufng-Wheel, of a feed-Wheel, holders by Which the articles to be buffed are carried and which are provided with plungers extending through openings in the -feed-Wheel and a shoe adapted to b'e engaged directly by the lower end of each plunger at the instant the corresponding holder passes under the buffing-Wheel so that an article upon the holder is placed in position to be acted upon by the bufting-Wheel.

3. The combination With a bufting-Wheel, of a feed-Wheel having openings, holders provided with plungers Which engage said openings and are guided thereby and an adjustable shoe lying in position to engage the plungers successively as the holders pass under the buffing-Wheel.

4. In a machine of the character described the combination With a buffing-Wheel, of a feed-Wheel, removable holders on the feed- Wheel by which the articles to be buffed are carried, each holder having a plungerextending through the feed-vvheel, a shoe lying in position to be engaged by said plunger successively as the holders pass under the buffing-Wheel, said shoe being provided with an ear Which is pivoted to a plunger passing loosely through J[he bed and set-screws 34 by Which either end of the shoe may be raised or lowered` 5. The combination with the bufing-Wheel, of a feed-Wheel lying at right angles thereto, holders in `the feed-Wheel each of which vis provided with a clip to hold an article to be buffed, and an adjustable shoe by which the holders are raised in turn as they pass under the buffing-Wheel, said holders being removably supported by the feed-wheel and adapted to be lifted therefrom or replaced during the rotation of said Wheel.

In testimony whereof I affix my signature in presence of tWo witnesses.

CHARLES I-I. CURTIS.
