UNITED STATES PATENT OFFICE.

JOHN J. I-IALIJEMAN AND ARNO N. VOGEL, OF SUNBURY, PENNSYLVANIA.

REED-POLISHING I MACHINE.

Application filed May 8,

To aZZ whom it may concern:

Be it known that we, JOHN J. HALDEMAN and AnNo lV. VoGnL, citizens of the United States, residing at Sunbury, in the county of Northumberland and State of Pennsylvania, have invented certain new and useful Improvements in Reed-Polishing Machines, of which the following is a specification.

This invention relates to improvements in reed polishing machines, and the like, and has for its object the polishing of reeds more rapidly and efiiciently than this operation can be performed by hand and more economically. It is an improvement on the Haldeman Patent No. 1,359,364t.

The various features of the invention will I be more fully described in connection with the accompanying drawings in which Figure 1 is an end elevation of the polishing machine.

Figure 2 is a top plan view of thesame.

Figure 3 is a detailed view of stone holding device.

Figure 4; is a detailed view of lifting devlce.

Figure 5 is a top plan view of the arms for holding the polishing stones.

Figure 6 is a front elevation of part of the series of stones and clamps.

Figures 7 and 8 indicate two sides of disc for graduated adjustment.

Figure 9 is a detailed view of connection between disc and operating arm.

Referring to the drawing, 1 indicates a fixed pulley on shaft 2, there being a loose pulley of same size adjacent to-it shown on Figure 2. Fixed on shaft 2 is a gear 3 adapted to mesh with operating gear 4: fixed on shaft 6. On the end of shaft 6 is a disc 7 (detail Figs. 789) having on the outer face a radial T shaped groove (Fig. 9) adapted to receive a T shaped bolt 9 on the shank of which is a roller bearing 1.0 which engages a slot 11 in a perpendicular operating arm 12. When the bolt 9 is near the centre of the disc 7 it will give but slight movement to the arm 12, and as it is moved toward the circumference of thedisc 7 the greater will be the length of the movement or stroke of the said arm. The stroke of the arm 12 is governed by the position of the bolt 9 in the disc 7.

In the inner face of the disc 7 is a radial groove 13 (Fig. 8) through which projects a small stud 14: fixed to the side of the bolt 9. Secured on the end of the stud 14 is a scale Pivotally attached to the operating arm 12 at 13 is a horizontal arm 13 which has adjustably mounted near its end a pair of polisher holder arms 15 The free end of arm 13 is rounded and threaded and over its end is screwed a cylinder 16 having a shoulder 17 at one end. A cylinder retaining ring 18 abuts against the side of the shoulder 17 on the end of the cylinder 16 and is held in place by set screws. An adjusting arm 19 its over the cylinder 16 and is secured thereon by means of a set screw (not shown). A jam nut 20 is screwed over the end .of the arm 13 and abuts against the end of the cylinder 16 and holds it securely in place. The function of the above described device is to place the polishing or abrasive stones on the ends of arms 15 in the center of the reed before fixing the length of thestroke. The arms 15 move in and out on the end of arm 13 and the extent of said movement may be regulated by Scale 21.

Pivotally secured on the ends of arms 15 are polisher holders 22, the up and down movement being limited by means of springs 23 at the top and bottom of arms 15. Secured in the holders 22 is a retainer 24, held in place by means of bolts fastened to same and passing through holes in top of said holders and locked by thumb nuts (1 which retainer secures guideways 25 for the stone keepers 26. On the top of the keeper 26 is a spring 27 which permits of a limited vertical 'movement of the said keepers 26 to accommodate stones of different widths. On one side of the holders 22 are shoulders 28 adapted to grip the retainers 2 1 and secure them in place. 29 indicates polishing or abrasive stones having the ends overlapping as shown,

so that although a number of stones may be used there will be one continuous polishing surface.

The polishing stones 29 are held in place by means of bowed spring retainers 30 and thumb screws 31, the retainers bearing against the ends of the sto'nes only, toprevent breakage of the same. Between the stones and the rear side of the keeper 26 is a rubber cushion 32 for the purpose of preventing any slippage or breakage of the stones.

33 indicates the bed of a guideway 9A, through the bottom of which operates a cam 35 having a roller 36' in the endof the same, and pivoted at 37. hen the cam 35 is raised by means of lever '88. it assumes the position-shown indotted line raising the movable arm 13'" which inturn lifts t he polisherstrom the reeds.

Pressure may be givento arm 18 by means of *a roller 39 on the top otthe same, said roller being held-in place by a U shaped bolt having the: legsv passing through the side walls of the guideway 34, secured by spring 40 and thumb nut tl.

The reed 42 to be polished is held in a bed by means'of clamps 43 which are adjustable by means of screw 4% which has a right and left thread. A lug &5"on' screw 4% is" held permanently in place by means of set screw 46 and its object is to limit the movement of the screw'tt.

A supplementary bed 41-7 is used in case any work is desired to bedone by hand.

The operation of the device is as follows g The reed to be polished is secured in clamps by the means described, the abrasive block or polisher' is placed'on the reed and the center of the same is located by the adjustment'means on the free end of rod 1-3. The length of the stroke of the'arm 13 may be regulated to accommodate reeds of different Width by the adjustment arrangement in disc 7 on shaft 6.

hat We claim as new anddesire to secure by Letters Patent is 1. In a polishing machine, the eombination with aholder for the article to be polished, of a plurality of horizontally movable operating'arms, means for limiting the stroke of said. arms, ofadjustable arms mounted on the endso'f said horizontally movable oper ating arms adapted to hold abrasive stones or polishers, means for adjusting arms to acconnnodate reeds of different widths.

2. In a polishing machine, the combination with a holder for the article to be polished, of a plurality of operating arms, means for limiting the stroke of said arms, of adjustable arms mounted on the ends of said operating arms having pivotally secured thereto holders for abrasive stones or polishers, means for adjusting saidarms to accommodate reeds of different widths.

3. In a polishing machine, the combination with a holder'for' the article to be pol ished, of plurality of operating arms, means for limiting the stroke of said arms, of adjustable arms mounted on the ends 'of said operating arms having pivotally secured thereto holders for abrasive polishers, means for securing the polishers in" said holders.

4 In a polishing machine, the combination with a holder tor the article to be polished, of a plurality, of operating arms, means for limiting the stroke of said arms, ofadjustable arins' mounted on the ends of said operating arms having pivotally secured thereto holders for abrasive polishers, of a plurality of polishers with overlapping ends, means for retaining the po'lishers in said' holders. i

5. In a' polishing machine, the combination with a holder for the article to be polished, of a plurality of operating arms, means for limiting the stroke of said arms, of adjustable arms mounted on the ends of said operating arms having secured thereto holders for abrasive polishers, of a plurality of polishers, of an elastic bufl'er for said polishers, means for throwing the polishers out of and into engagement: with the article to be polished. i

In testimony whereof we afiix our signatures in presence of two witnesses.
