- zontal position.

The film spool guard 16 is mounted loosely upon the forward end of the shaft 8 and the film spool 17 is mounted loosely upon the forward end of the shaft 8 against the guard 16. The bar 18 is connected to the lower end 15 by a hinge 19 and swings upwardly into a position parallel with'the bar 11 and against the front side of the spool 17, and the shaft 8 extends through the central opening 20 in the bar 18. A spring catch 21 is formed at the forward end-of the end portion 14, so that the upper end of the bar 18 will be held by the catch 21.

When it is desired to remove the spool 17 carrying the roll of film 22 or to remove 'the empty spool the upper end of the bar 18 is manually grasped and pulled outwardly and swung downwardly on the hinge 19 then a new spool and roll of film may be placed in position against the guard 16 and the bar 18 swung upwardly and latched while the film is being unwound.

The spool of film 22 to be polished is mounted upon the shaft 8- and passes upwardly around the roller 23 and in passing over the roller 23 the film ismoistened with alcohol from the moistener 24.

The details of the moistener 24 are shown in Figs. 1, 2, 6 and 7 and are as follows:

A stand 25 is mounted upon the top 1. A stub shaft 26 is fixed horizontally through thetop of the stand and the roller 23 is mounted loosely upon the front end of the shaft 26. An attaching plate 27 is secured to the top of the stand 25 and a post 28 extends u wardly from the forward end of the plate 2 A hearing 29 is inserted loosely downwardly upon the post 28.

The alcohol pct 30 is formed integral with the bearing 29 and has an alcohol chamber 31 leading upwardly and a passage 32 leading downwardly. Alcohol is placed in the chamber 31. Wicking 33 is placed with one end inthe chamber 31 and the wicking is bentover and inserted downwardly through the passage 32 to engagethe film 22 as the film passesover the roller 23. The cap 24 covers the pot and wicking.

The wicking bearing upon the film 22 supports the pot 30 and as the wicking wears away the bearing 29 will move downwardly upon the post 28. A regulating plate 34 is placed in the passage 32 against one side of the wicking 33 and a wing head screw 35 is tapped through the wall against the plate 34, so that by manipulating the screw 35 the pressure upon the Wicking 33 may be increased or decreased to regulate the flow of alcohol through the wicking to the film.

The buffing stand 36 is mounted upon the top 4 a short distance from the stand 25. The guide roller stand 37 is mounted upon the top 4 a short distance from the stand 36'. The second bufling stand 38 is mounted a short distance upon the opposite side of the stand 37 from the stand 36 and thefeed roller stand 39 is mounted some distance behind the stand 38.

The guide roller stand 40 is mounted between the stands 38 and 39. vThe belt 41 'runs'around the roller 23 upon the stand 25 under the bufiing wheel 42 upon the stand 36, over the guide roller 43 upon the stand 37 under the buffing wheel 44 upon the stand 38, around the driving roller 45 upon the stand 39, over the gripping roller 46 upon the stand 40, and under the gripping roller 47 upon the stand 40 and back to the roller 23, and the film 22 is carried by the belt 41 from the roller 23 to the roller 46 and then the film passes to the rewinding spool 48.

As the film passes over the roller 23 upon the belt 41 the film face to be polished asses the wick 33 and is moistened with acohol then the film passes under the 'bufling, Wheel 42. The rollers 23 and 34 sustain the belt and film, and the buffing wheel 42 bears downwardly upon the film and belt between the rollers 23 and 43. so that the contact between the film and the bufling wheel is substantially yielding for the purpose.

The buffing wheel shaft 49 is-mounted in bearings 50 and 51 in the stand 36, and a pulley 52 is fixed upon the rear end of the shaft 49 and is driven by a belt 53 running over a pulley 54 upon the motor shaft 55. The belt 53 runs through an opening 56 in the top 4. The guide pulley 43 is mounted upon the stub shaft 57 extending through a slot 58 in the stand 37, the shaft 57 being provided with a shoulder and nut, so that the shaft maybe raised or lowered to the extent of the slot 58 to adjust the tension upon the belt 41 and to adjust the pressure upwardly against the bufling wheels 42 and 44.

The bufiing wheel 44 is mounted upon the shaft 59 extending through bearings 60 and 61in the stand 38'and a pulley 62 is fixed upon the rear end of the shaft 59 and is driven by a belt 63 running through an opening 64 in the top 4 and around the pulley 54 upon the motorshaft 55.-

I The driving pulley 45 is fixed upon a shaft 65 extending through bearin s 66 and 67 and a pulley 68 is fixed upon t e rear end of the shaft 65 and is driven by a belt 69 extending through an opening 7 O in the top 4. The pulley 45 drives the belt 41 and the tension of the belt 41 drives the pulleys 46 and 47.

The details of the stand 40 and rollers 46 and 47 are shown in Figs. 1, 2, 8 and 9 and are as follows: i

The stand 40 has a bearing 71 atits top. The lever 72 fits against the front end of the bearing 71. The bolt 73 is inserted through the lever 72 and through the bearing 71 and has a head 74 upon its front end, a shoulder 75' engaging the front end of the bearing 71, and a nut 76 upon its rear end, so that by tightening the nut the shoulder 75 tightens against the bearing 71 to hold the bolt rigid and leaves the lever 72 free to swing. The normal position of the lever 72 is horizontal. A bolt 77 is inserted throughone end of the lever 72 and the roller 46 runs loosely upon the forward end of the bolt 77. A bolt 78 is inserted through an eye 79 and through the opposite end of the lever 72 from the bolt 77, and the roller 47 runs loosely upon the forward end of the bolt 78.

The eye 79 is formed upon the upper end of a tension bolt 80 and the bolt 80 extends downwardly through the top 4. An expansive coil spring 81 is placed around the bolt 80 below the top 4. A spring seat 82 is placed upon the bolt against the spring and nuts 83 are placed upon the bolt to support the spring seat 82. The tension of the spring 81 is exerted to pull the roller 47 downwardly and swing the roller 46 upwardly to tighten the belt 41 and to grip the film 22 against the belt 41 as the film passes over the roller 46 and the tension of the spring is regulated. by manipulating the. nuts 83.

From the roller 46 the film 22 passes to the r'ewinding reel construction 84, and referring to Figs. 2, 3, 4 and 5 the details are as follows:

A shaft hanger 85 is secured against the lower face of the top 4. and has a bearing 86 at its lower end. A shaft 87 is rotatably mounted in the bearing 86. A collar 88 is formedupon the shaft 87 against the front face of the bearing 86. A bar 89 fits loosely upon the collar 88 and extends in a vertical position and is secured to the top 4 by a screw 90 inserted through the upper end of the'bar 89, through the block 91 and into the top 4.

The upper end 92 of the bar 89 is bent forwardly to a horizontal positionand the lower end 93 is likewise bent forwardly to a horizontal position. The film guard 94 fits loosely upon the shaft 87 against the collar 88. A spline 95 is fixed in the shaft 87 and extends forwardly from the collar 88 through the guard 94. The spool 48 fits loosely upon the shaft and is held to rotate with the shaft by the spline 95. The film 22 is rewound upon the spool 48.

The bar 96 is connected to the end 93 by a hinge 97 and swings upwardly to a position parallel with the bar 89 and against the front end of the spline 48 to serve as a guard to hold the film 22 between the guard 94 and the bar 96. The shaft 87 extends through the bar 96. A spring catch 98 is formed upon the forward end of the upper end 92 of the bar 89 so that when the bar 96 is swur g upwardly into its normal position the catch will hold the bar during the operation of rewinding the film. When the bar 96 is swung downwardly the spool and film inlaydbe readily removed and a new spool app 1e ,l

A flange 99 is mounted upon the shaft 87 against the rear side of the bearing 86 and is held in place by a pin 100. A friction plate 101 is placed against the face of the flange 99. he pulley hub 102 is placed loosely upon the shaft 87 against the friction plate 101. The friction plate 103 is placed against the opposite side of the pulley hub from the plate 101. A flange 104 is placed loosely upon the shaft 87 against the friction plate 103. A keyway 105 is formed in the shaft 87 and a pin 106 is fixed through the flange 104 and extends into the keyway 105, so that the flan 104 may slide endwise upon the shaft 8%, and is held to rotate with the shaft.

An expansive coil spring 107 is placed upon the shaft 87 against the flange 104; A spring seat 108 is placed upon the shaft against the spring 107. A nut and hand wheel 109 is screw-seated upon the shaft'87 against the spring 107 so that by manipulating the hand wheel nut 109 the tension of the spring 107 is regulated to regulate the friction betweenthe friction plates 101 and 103 and the pulley hub 102 to drive the shaft 87 from the rotation of the pulley hub 102 and to allow the shaft 87 to slip when the strain upon the film requires'it.

The shaft 8 extends backwardly beyond the bearings 9 and 10 and the shaft 8 is rigidly held from rotation. The idler pul ley 110 is loosely mounted upon the shaft 8 and is driven by a belt 111 running around the pulley 54 upon the motor shaft 55. The reducing pulley 112is formed integral wlth the pulley 110. A pulley 113 is formed upon the pulley hub 102 and a belt 114 runs around the pulleys 112 and 113. The pulley 115 is formed upon the pulley hub 102 and the belt 69 runs around the pulley 115 and around the pulley 68.

The rewinding reel construction 84 winds the film 22 upon the spool 48 and of course as the roll of film increases in size the peripheral speed increases and the tension 'and not pull too hard upon the film.

Thus I have produced a continuously op erating film polishing machine comprising a driving pulley, an idler pulley mounted on a level with the driving pulley, a belt traveling around the driving pulley and the idler pulley, a spring pressed belt tightener over which the belt travels, an adjustable guide pulley over which the upper side of the belt travels, bufling wheels mounted on each side of the adjustable guide pulley, a moistener mounted above the idler pulley, and a rewinding reel construction frictionally driven and mounted to take the film from the belt tightener so that a roll of film may be mounted upon the unwinding reel construction and run around the idler pulley upon the belt under the moistener under the first buffing wheel over the adjustable guide pulley under the second bufiing wheel around the driving pulley and around the belt ti-ghtener to the rewinding reel construction.

Various changes may be made without departing from the spirit of my invention as claimed.

I claim:
