21 claims. (ci. zei-sas) This invention relates to apparatus for polishing or burnishingmaterial, and is more particularly adapted for use in polishing galvanized wires, rods and the like, and an object oi' this invention is to provide an improved construction that will be automatic and continuous in. operation, and which will insure accuratepolishy ing of the material at a relatively low cost.

One of the objects of my invention relates to the means whereby the pressures of the polishy 'ing dies which engage opposite sides of the wire are controlled by a pair oi' pivoted levers which -are actuated by centrifugal force when the polliizing frame body of the machine israpidly ro- `Another feature of the invention relates to the manner'oi controlling the swinging movement of the pivoted levers so that they will swing inwardly or outwardly in unison.

Another object of my invention relates to the L manner of adjusting the pressure of the polishlng dies on the material as lt passes through the specification and in which like characters of rei'- erence indicate like parts: f Figure 1 is a vertical longitudinal section of the swinging movement of the levers.

Fig. 5 is an end elevation of the block shown in Fig. 4.

Fis. 6 is a bottom plan view of the die blockv with the die in place.

Fig. 7 is a plan view of one oi the pivoted swinging levers and'Fig. 8 is adetail transverse section taken on the line [-4 ot Pig. '1.

Referring now to thevarious characters of reference on the drawing, the numeral iv designates the bed of the machinewhich is support-` ed in any suitable manner, 2 'a pair ot spaced journal bearings each provided with a roller -bearingl 3. therein for receiving and s'uwortint the reduced tubular neck ends I o! aV cylindrical A polishing frame body l. 'me roller bearings 3 are held lnposiuon on the tubular' necks t by means of the bushings 6 and the bearings 2 are .further equipped with oil seals 1 and oil inlet supply valves or the like l.

The cylindrical polishing frame body 5 is provided at its intermediate portion with a transverse rectangular opening 9, which is reduced in width at one'end as at 'il for receiving a pair of swinging levers il and mutilated gears l2 and i3 respectively, and centrally disposed at the opposite end of said rectangular opening 9 the polishing frame body 5. is formed with a pair of aligned grooves Il and transversely extending cylindrical slideway openings I5 f or receiving the cylindrically shaped die holder blocks I6 for the polishing dies l1'.

The 4pair of swinging levers I I are lduplicates and disposed longitudinally and in transverse alignment with each other at opposite sides of the machine, with their intermediate portions in the grooves Il and pivoted to the polishing frame body 5 by means oi bolts Il. One end of each swinging lever il is adapted to extend into a rectangularopenlng I9 in one of the die nolde blocks lc as indicated more clearly m Figs. 1 and 2-and is pivoted by means of a pin 2lA to a pair ot liner plates 2l whichare adapted for a slight sliding movement in relation to the t die holder blocks II to compensate for the slight arc shaped path of travel of the pin 20 during The inner face oi each `die holder block Ii is provided with a dovetailed recess 22 for receiving the polishing die l1 formed of hard steel or alloy such as its inner face highly polished.

Theopposite end of each swinging lever Il is formed with a rack 23 for meshing with one of the mutilated gears i2 or I3 as the casemay be. The intermediate portion oi each swinging lever li is'also provided 'at spaced intervals with sockets 24 and holes 25 for receiving cap screws 28 by means of which a weight 2l may 4be adJust position they are each formed with `ably attached to each swinging arm. and in order that the weights may be more rmly held in a channel as at 2l.

The mutilated gears i2 and i2 are o slightly ldiilereni; formation and are disposed in the rel frame body l and the necks 4 therefor asindi- 'cated in Fig. 1 are formed tubular with the opening connected together centrally betweenthe swinging` levers li and mutilated gears l2 and faces equally aswell.

I3 by means of a pipe section 34, and to allow for clearance between the weights 21 and the mutilated gears vthey are provided with arcf shaped grooves 35 and 36 respectively. This pipe section 34 is plain at one end and vis inserted in the opening 33 adjacent to the burnishing dies I1 lat one end of cylindrical polishing frame body i,

l ishing frame body one of the neck ends is provided with a pulley 42 which is keyedto the neck 4 as at 4S and held in position by means o i a nut 44 threaded on the end of vthe neck and a lock l washer 4i.

This machine may be adapted for. use as a right or left hand unit. When assembled as a right hand unit the parts will be disposed in the position shown in full lines, but for a left handunit the pulley will be mounted on the neck at the4 opposite end of the machine as indicated in dotted lines at 46, and the iournal bearing with the larger roller bearing 3 will also be mounted at that end of the machine.

As it is desirable to inspect the polishing dies I1, transverse openings 41 are formed in the cylindrical polishing frame body 5.

The operation of the machine is as follows: assuming that the machine is not operating and the dies are closed with their polishing surfaces in contact with each other and the swinging levers II in the position' indicated in dotted lines in Fig. 1 the operator presses the swinging levers inwardly thereby opening the dies to their full extent.`

The end ofthe plated wire to be polished which may be received in the usual manner from a payout reel located adjacent to the end of the machine is inserted manually into the central opening 33 at the right hand end of the machine and advanced through the roller guide 33, pipe section 34, between the polishing dies I1 land out through' the opening 33 at the left hand end of the machine, the endof the wire is then attached to a take-up reel. 'I'he cylindrical .polishing frame body 5 and the parts associated therewith are then rotated rapidly by means of a motor or the like having a belt connection with the pulley 42. As the take-up reel advances the wire through the machine the faces of the polishing dies are pressed flrmly against4 the plated surface of the wire as it is rotated around the same by means of the centrifugal force of the weighted swinging levers. This pressure may be varied by adjusting the weights on said swinging levers,

t while the mutilated gears I2 and I3 engaging the racks-23 insure a uniform infand-out movement of the levers.

For illustration I have'described my invention as particularly adapted for use in polishing galvanized wire but I wish it understood that other kinds of plating may be polished or dies could be used for cleaning, scouring or grinding wire sur- Although I have shown and described my invention in considerable detail, I do not wish to be limited to the exact construction shown and described, but may use such substitutions, modications or equivalents thereof, as are embraced within the scopeof my invention, or as pointed out in the claims. i
