WIRE-POLISHING. MACHINE.

Patented June 22, 1909.

Application filed February 28, 1908. Serial No. 418,209.

To all 'uihom itvriay concern: Be it known that I, HENRYJANSSEN, a

citizen ofthe United States, and a resident of the Borough of W'yo'missing, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Wire-Polishing Machines, of which 7 the following is a s ecification.

My. invention re ates to machines for mechanically polishing the surface of passing rods or wire.

The-invention consists in providing in connection with a rotary hollow spindle through which this rod or wire is suitably passed, pivotally mounted arms on said spindle carrying polishing devices adapted to be closed together uponthe rod or wire bycentrifugal action of said pivoted arms due to rotation of the spindle; and further in providing for readily varying the olishin'g .pressure thus produced; as fully escribed in connection with the accompanyin drawings, the novel features being specifica ly pointed out in the claims. a

Figure 1 is aside elevation of a polishing head embodying my invention in preferred form. Fig. 2'is a partial lan view of the same. Fig. 3 is a se arate vlew of the weightengaging sleeve. ig.-4 indicatesa modified construction.

The hollow spindle a, as shown, is mounted v in fixed bearings b 6 between which it is provided with a drive pulley 0. At its forward end is secured a carrier-head (1, formed with pivot-jaws e and c in which are mounted similar centrifugally movable arms f f having polishing devices fitted thereto.

These devices as indicated comprise similar die-blocks g 9 having their opposed faces grooved to suitably contact with the surface of the rod or Wire, and'e'achentered .in a pocket It formed in a forwardly projected portion of an arm f ,*the blocks being backed by pivotpins h in the respective pockets, upon which.

they are free to rock so as to insure their hearing uniformly against the interposed rod or wire when in action. T Upon the rear- Wardly extending ortions of each arm f is inounted a weight in the form of a sliding sleeve, the degree of pressure exerted through centrifugal action, upon the passing rod or wire, at a given speed ofrotation of the spindle, being determined, by the location of these weights at agrater or less distance from the pivotal connections f f of the arms. To rovide for conveniently adjusting sleeve without interfering with the free swingthe of the arms due to centrifugal force; weights k as shown being provided with grooves k, and a pair of fingers being arranged fork-likein each groove. 7 The adjustment of the sleeve m on the s indle to thus vary the polishing pressure, s ould be so effected that it may. be conveniently accomplished Without interference with the running. of the machine; and for this purpose I employ a non-rotating sleeve-adjustmg device consisting of a sleeve-en aging slide 17, movable in a suitable guideate g, fixed to the top of bearing b. This slide, as shown, is provided with a clamping screw p extending through a slot g in the plate q, and its hooked outer end p is engaged in a circular groove m in said sleeve so that the position of the latter may be readily changed as desired while the sleeve'is being rotated surfaces, though other suitable material may 4 be employed. The swing of the pivoted arms may be positively limited as by means of slots (1 therefor in carrier head d, as indicated in Fig. 1. Though the intermediate pivoting of the arms to the carrier-head, as described, is preferred, they may be pivoted thereto at one end for instance as indicated in Fi 4, each polishing device g in the latter case" eing extended around, the rod or wire operated upon so as to bear against the opposite side thereof under centrifugal action, as indicated. Other modifications may obviously be devised without departing from the invention.

What. I claim is 1. A wire or -rod polishing machine com prising a hollow rotary spindle and centrifugally movable arms pivoted thereto and pro; vided with polishing devices, said devices being closed together at the spindle axis by the pivotal centrifugal movement of the rotated arms.

2, A wire or rod polishing machine comprising a hollow rotary spindle and centrifugally movable arms pivoted thereto and provided with polishing devices and adjustable weights, said devices being closed together at the spindle axis by the pivotal centrifugal movement of the rotatedarms.

3. A wire or rod polishing machine comprisinga hollow rotary spindle, centrifugally movable arms pivoted thereto and provided with polishing devices, Weights slidable on said arms, and a longitudinally adjustable sleeve on said spindle engaging said weights.

4. A wire or rod polishing machine comprising a hollow rotary s indle, centrifugally movable arms pivoted t ereto and )rovided with polishing devices, weights sli able on said arms, a longitudinally adjustable sleeve on said spindle engaging said weights, and non-rotatlng adjusting means for said sleeve.

5. A wire or rod polishing machine comprising a hollow rotary spindle, oentrifugally movable arms pivoted thereto and having forwardly rojecting ortions provided with polishing evices and rearwardly extending portions provided with slidable weights, and

30 a longitudinally adjustable sleeve on said spindle engaging said weights, substantially as set forth.

' 6. A wire or rod polishing machine comprising a hollow rotary spindle, centrifugally movable arms pivoted thereto and having with polishing devices, grooved weights slidable on said arms, and a longitudinally adjustable sleeve on said spindle having forked fingers engaging said grooved Weights.

8. A wire or rod polishing machine comprising a hollow rotary spindle and centrifugally movable arms provided with polishing devices, said devices being closed together at the spindle axis by the centrifugal movement of the rotated arms,

In testimony whereof, I affix my signature, in the presence of two witnesses.

HENRY JANSSEN. Witnesses:
