APPARATUS FOR SUPPLYINGABRADING AND POLISHING MATERIAL TO CUTTING AND POLISHING TOOL S.

SPECIFICATION formingpart of Letters Patent N0. 283,273, dated August 14, 1883,

Application filed June 23, 1883. (No model.)

To all whom it may concern Be it known that I, JOHN S. OConnon, of

White Mills, in the county of Wayne and State of Pennsylvania, have invented a new and useful Improvement in Apparatus for Supplying Abrading and Polishing Material to Cutting and Polishing Tools; and I do. hereby declare that the following is a full, clear, and exact description of the same. In the process of manufacturing line out glassware the operations of cutting and p olishing are performed by a revolving wheel run at high speed, in contact with which the glass article is held by the operator. In the process of polishing, the periphery of the wheel must be constantly supplied with polishing material, as otherwise the heat generated by the friction would crack the glass and ruin the articles. The method commonly employedin glass-works is to have the polishingpaste supplied to the wheel by a boy with a brush, under the supervision of the cutter. This method, besides entailing the expense of an additional operative, is objectionable, because carelessness or inattentionon the part of the boy may ruin valuable articles of glassware, and a certain percentage of loss from this cause occurs in all glass-factories.

My invention relates to means for supplying polishing material to the polishing-tool; and its object'is to apply such material by means of a connected automatic mechanism under control of the operator.

My invention consists, first, in combining with the polishing-tool and positively-operated pastesupplying devices means under control of the workman for throwing such devices out of and into gear with the drivingpower; further, in combining with the polishing-tool abrush revolving so as to come in contact therewith, and a supply'or receptacle for polishing-paste or other material; further, and finally, in the peculiar and improved construction of the apparatus and its various parts, as fully hereinafter described and claimed.

In the drawings, Figure 1 is a cross-section through the paste-receiver, showing the driving-shaft andpolishing or cutting tool in elevation. Fig. 2 is a perspective of the pasteapplylng mechanism upon a larger scale. Fi 3 1s a slmllar view of the whole apparatus.

In Fig. 1, A represents a frame-work of any suitable kind, and B is a shaft running in adjustable boxes at a. Upon this shaft is mounted the polishing or cutting wheel 0, of ordinary construction. The shaft and wheel are driven by a belt from the pulley Z1 to any suitable power. Upon two of the cross-beams of the frame is supported a box, D, withinwhich is held a box, D. The box I) is movable within the box D, and is made water-tight to hold the polis'hingpaste.

The devices for applying thepaste to the wheel are shown in detail in Fig. 2.

F represents a standard composed of arms ff, having set-screws for attachment to asupport. Formed with this standard are upwardly-projecting arms G G, the top of each of which is flattened and formed into a half bearing for the transverse shaft H. The bearings are completed by boxes g 1/. Running loosely on the shalt H is a cone-pulley, I, which is connected by a round belt, 71 to a drivingshaft. (Not here shown.) Upon one side of the pulley is a flanged or grooved boss, The box r/ is extended to form a plate, 7', upon which slides a bar, is, passing through a guide, Z. The bar 7.: has a finger, m, which engages with the flange in the boss 2', and such bar I; is moved longitudinally by a pivoted handlever, J. Uponthe opposite side of the pulley I is secured one half of a. toothed boxclutch, K. The opposite half, K, is keyed upon the shaft H just within the bearings. As the clutch K revolves constantly with the pulley I, it is clear that the movement of such pulley may be communicated to the shaft by sliding the pulley on the shaft and locking the clutches. The sh aft H is extended beyond the bearing 9, and upon it is adjustably secured, bya set-screw, n, a holder, L. In this holder is adjustably secured the handle of a brush, M, the construction allowing the brush to be adjusted both vertically and laterally. The brush will thus revolve with the shaft or remain stationary, according to the position of the clutches.

This apparatus, as thus described, is mounted upon the edge of the box D, as shown in Fig. 3, and the inner box partly filled with the polishing-paste. The brushis so adjusted that it will dip into the paste at each revolution, and when in gear will also come in contact with the polishing-wheel, keeping it eonstantly supplied with polishing material, without any attention or care on the part of the operator. As each article is finished, or at will, it is an easy matter to move the lever and disengage the clutches, when the revolution of the shaft and brush will cease. The brush ordinarily revolves at a speed of sixty revolutions per minute.

Having described my invention, I claim-- 1. Combined with a cutting or polishing tool, a device for supplying polishing material to such tool, mechanism for operating such device, and means under control of the operator for throwing such device into and out of gear with the driving mechanism.

2. Combined with a polishing-tool, a reservoir of polishing material and a revolving brush, operated by mechanism substantially as described, so as to supply the tool with pol ishing material at intervals.

3. Combined with a polishing-tool reservoir to contain polishing material, avertically and laterally adjust-able brush, and mechanism, substantially as described, for causing such brush to revolve.

4. The shaft H, in combination with the loose sliding pulley I, the locking-clutch, the revolving brush, the polishing-paste receptaele, and the polishing wheel or tool.

5. The shaft H, l'oose pulley I, having grooved boss, the sliding bar and operatinglever, the clutches K K, and the brush and polishing-tool.

In testimony whereofI have signed my name to this specification in the presence oftwo subscribing witnesses.

JOHN S. O CONNOR.
