' Application nea March s1, 190s.

l .To all whom t may concern.-

Be it known that I, FRANCIS A. WEIS- BECKER, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Metal-Polf ishing Machines, of which the following is a specication, such as will enable those skilled in the art to which it appertains to make and use the same.

4 The object of this invention is to provide an'` improved machine for polishing sheet metal, and which is simple in construction and op-` eration and comparatively inexpensive and by means of which sheet metal of any kind or class may be quickly, easily, and conveniently polished at` a comparatively light eX- pense; andwith these and other` objects in view the invention consists in a machine of the class and for the purpose specified constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Figure l is a front view of my improved polishing-machine; Fig. 2, a section on the line 2 2 of Fig. l; Fig. 3, asection on the line 3 3 of Fig. l, and Fig. 4 a section on the line 4 4 of Fig. 2. j

In the practice of my invention I provide a strong and substantial frame, which in the form of construction shown comprises end plates d, connected by cross-rods a2, and this frame is preferably provided with a top cover1 0,3, in which is mounted a shaft b, which passes therethrough and is provided at one end with a tight belt-wheel b2 and a loose belt-wheel h3 and which is also provided at theopposite en d with a pulley or belt-wheel b4. Mounted on the shaft b, within the top portion a3 of the main frame of the machine, is a roller c, which preferably consists of 'a central portion c2, covered by lagging c3, of wood, over which is placed polishing material c4, which may consist of felt, ne brush ma- I terial, or any other suitable substance usually 5o employed in polishing or bufling machines. Below the roller c is placed a transverse feedshaft d, which passes through vertically-ari Serial No. 150,352. (No model.)

ranged slots or openings cl2 in the end memu bers d of the mainframe, and the ends of said shaft pass through vertically-movable bearings cl3, mounted in said slotsoropenings, and the position of these bearings may be regulated vertically, by means of regulatingscrews d4, which pass through suitable supports d5 and are provided with heads or handles (Z6, by which they may be operated, and by means of this construction the shaft d may be adjusted vertically and with reference to the polishing-roller c. lnfrontpof and slightly below the shaft d is a supplemental brushroller e, the shaft c2 of which is movable in segmental slots e3 in, the end members a of themainframe, and the ends of this shaft pass through arms e, pivoted at the ends' to the main frame at e5, and by raising and lowering the arms c4 the position of the brush= roller e may be adjusted with reference to the position ofthe polishing-roller c and the shaft d, and the arms e? are provided with set-screws or other suitable device e6, by which they l may be secured at any desired pointof ad justment` The frame rod a2, which is arranged in front of and slightly above the brush-roller e,

4is provided with spring-fingers f, having collars f2, through which the said rod a2 passes, and thesecollars are provided with set-screws f3, and said spring-fingers may thus be ad-` justed or raised and lowered as may be desired, and the operation thereof will be hereinafter explained.

The shaft d, the central portion of which serves as a feed-roller and is larger than the ends thereof, is also provided at one end with a drive-wheel C17, and the shaft e2 of ,the brushroller e is provided at one end witha pulley or belt-"wheel el, which is geared in connec-' tion with the pulley or be1t-wheel b4 by a belt or other suitable device g, and in practice the machine is operated by means of the wheels h2 and CP, which are geared in connection with a main power-shaft, which is not shown,

or which may be geared in connection with l any suitable power device.

In the bottom portion of the main frame is mounted a receiver h, intended to receive the metal plates after they have been passed through the machine, and this receiver is preferably of the form shown in Figs. 2, 3,'

and 4, being deeper at the front than at the rear thereof and being inclined downwardly and forwardly and being also supported by means of side plates h2, pivoted thereto and provided with longitudinal slots h3, through which are passed bolts or screws h4, which are passed into the end portions a of the main frame, and by means of this construction the position of the receiver h may be regulated and adjusted as desired.

In the operation of this-machine the metal plates are fed through the machine in the direction of the arrow in Fig. l, the position of a plate being indicated by the dotted lines m2, and in this operation the plates are passed over the spring-fingers f, over the brushroller e, and between the feed-roller d and the polisher c.

It will be understood, of course, that the shaft ZJ and rollers c may be driven at any desired speed, and with the construction shown the roller e or the shaft thereof will turn with the same speed as the shaft b. The feed-roller CZ may also be turned at any desired speed, but in practice is preferably turned at a much lower speed than the polishing-roller c; but it will be understood that the speed of the revolution of the brushroller e, the polishing-roller c, and the feedroller d may be regulated as desired.

In practice the brush-roller e serves to clean the bottom of the metal sheet and to partially polish the same as it passes through the machine, while the polishing-roller c operates to thoroughly polish the upper surface of said sheet. After the sheet has passed through the machine or between the roller c and feed-roller d it drops into the receiver 7i and slides downwardly and forwardly and may be removed therefrom in any desired way. The receiver h is also intended tooontain a lacquer or other suitable polishing liquid, and after the sheet has been passed once through the machine it may be removed from the receiver h and again passed through the machine, and in this operation it may be reversed, so as topolish both sides thereof.

The spring-fingers f may be adjusted so as to regulate the pressure of a sheet of metal on the roller e or so as to raise said sheet, and thus present a greater portion of the upper surface thereof to the polishing-roller c, and it will be apparent that the polishing-roller c, the feed-roller d, and the brush-roller e may be driven in any desired manner.

My improved polishing-machine is simple in construction and operation and comparatively inexpensive and is not liable to get out of order or frequently need repair, and by means thereof sheets of metal of any kind vsao i or class may be quickly polished either on one or both sides.

Having fully described my invention, what I claim as new,.and desire to secure by Letters Patent, is-- l. In a machine of the class described, a frame, a polishing-roller mounted in the top portion thereof, a vertically-adjustable feedroller mounted below the polishing-roller, and a brush-roller mounted below the polishingroller and in front of the feed-roller and ad j ustable toward and from the polishing-roller,

substantially as shown and described.

2. In a machine of the class described, a frame, a polishing-roller mounted in the top portion thereof, a vertically-adjustable feedroller mounted below the polishing-roller, and a brush-roller mounted below the polishingroller and in front of the feed-roller and adjustable toward and from the polishing-roller, and a rod passing transversely through the frame in front of the brush-roller and provided with backwardly-directed .spring-fingers which are vertically adjustable, substantially as shown and described.

' 3. In a machine of the class described, a

frame, a polishing-roller mounted in the top thereof, a feed-roller mounted below the polishing-roller, a brush-roller mounted below the polishing-roller and in front of the feedroller, -a rod or support passing transversely through. the frame in front of the brush-roller and a receiver mounted in the frame below said rollers and extending upwardly and rearwardly of the frame,.substantially as shown' and described. i

v4. In a machine of the class described, a frame, a polishing-roller mounted in the top thereof and vertically-adjustable feed-roller mounted beneath the polishing-roller, abrushroller mounted in front of the feed-roller and below the polishing-roller, a frame-rod arranged in front of the brush-roller and parallel therewith and providedv with verticallyadjustable fingers and an adjustable receiver mounted in the bottom portion of the frame and held in an upwardly and backwardly position and adapted to receive sheets of metal after they have passed through the machine, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of the subscribing witnesses, this 20th day of February, 1903.

FRANCIS A. VVEISBECKER.
