Application December 28, 1939, Serial No. 311,239
- 3 Claims. (01. 51-194) proved construction, designed to so function that the surface treated shall receive a finish of extreme evenness.
Another object hereof is to provide a novel and improved machine of the character set forth,
which insures maximum effective use of the abrasive or other finishing agent employed.
A further object of the present invention is to provide a machine of the class mentioned, of novel and improved construction, which is simple to manufacture, easy to operate, employing no mechanism which is apt to get out of order other than by natural wear, and which is highly efficient in carrying out the purposes for which it is designed.
85 Other objects and advantages gained, will become manifest as this disclosure proceeds.
In the accompanying drawing forming part of this application, similar characters of reference indicate corresponding parts in all the views.
80 Fig. 1 is a front view of a machine embodying the teachings of this invention, shown however without the finishing material.
Fig. 2 is a section taken at line 2--2 in Fig. 1.
Fig. 3 is an enlarged fragmentary, partially sec- 35 tional view taken of the machine at line 3-3 in Fig. 2.
Fig. 4 is a perspective view in reduced scale, showing the gearing system included in said embodiment.
40 Fig. 5 is a diagram used in the following description to aid in explaining operation of the machine.
In the drawing, the numeral l5 designates generally a revolvably mounted drum or reel structure,
45 comprising the end disc members [6 and I1, maintained in spaced relation by the tie rods l8, l9 and 20 between them; said rods being parallel with the main shaft 2| to which the drum I5 is keyed as at 22, or otherwise suitably secured.
50 Each roll of finishing material is mounted on a shaft 23, and is adapted to be wound up on shaft 24 by mechanism hereinafter described. Each roll of such finishing material, therefore has an unused portion and a used portion 25 with 55 connecting web portion 25". I have chosen to ing the gears 3| and 32.
show a machine employing two such rolls of material to accomplish balance. Of course, machines constructed in accordance with this invention may be made having any number of such roll systems, depending upon the size of the ma- 6"- chine and its intended use. The pairs of shafts 24 and 23, all parallel with the main shaft 2|, are preferably, but not of necessity, equi-distant from said main shaft, and equi-distant from each other, for symmetry of design and balance. 7 10- The roll portions may reside in casings 26', cylindrical in shape, extending across the end members it and [1, each of which casings has a longitudinal opening 21 through which the roll material runs. means in place thereof, extend across the reel structure 15', projecting radially outwardly, one beyond each of the casings 26, and create the operating lanes for the web 25" of the finishing material passing over said resilient means, from 20 the shaft 23 to the rewind shaft 24 in each instance, when said brushes 28 pass over the surface 29 to be treated. The tie rods l8, I9 and 20 are so placed that they serve as guide rollers for the web 25.. in contact with the surface 29 only at the operating'lanes'it is desirable that rods 2!] lie nearer to the main shaft 2| than the brushes 28.
On the main shaft 2 l, is a loose sleeve 30 carry- Each of the rewind 30 shafts 24 is demountable. from, and is driven by a gear 33; each such shaft carrying one such gear 33. A gear 34 is keyed as at 35 or otherwise securely mounted on the main shaft 2|. A countershaft 36 has mounted thereon the gears 31 35 and 38; the former in engagement with gear 34, and the latter in engagement with the gear-3|. By example, and not as a limitation, the gears 32, 33, 34 and 31 are identical, in that, let us say, they each have sixty teeth, while gear 38 has 40 sixty-one, and the gear 3|, fifty-nine teeth. Now I will refer to thediagram shown in Fig. 5, which will aid in explaining the operation of the machine.
If gear G is secured to the main shaft 2|, and is in engagement with gear 33, then upon rotation of the drum structure l5, as for instance by the belt drive 39, gear 33 will not be revolved about its own axis. If gear G is loose on shaft 2|, and is in engagement with the gear 33, then upon rotation of IE, the gear 33 will not revolve about its own axis, if the angular velocity of gear G equals the angular velocity of the shaft 2|, but will revolve when such angular velocities are different; the amount of angular movement of any Brushes 28, or other resilient In order that the web 25 come 25* 2" I fl 2,198,047
radius of gear 33, being a measure of such difference. Referring now to the gearing system included in the machine, I have chosen that the angular velocity of the sleeve 30 shall slightly exceed the angular velocity of the main shaft 2 I, that is, the effective driving of the gears 33, is about the movement of two teeth per full revolution of the main shaft 2|. In other words, what I have accomplished is that the finishing material will be wound up on the shafts 24, extremely slowly as the drum structure l5 revolves in the relation of about one revolution of the wind up shafts 24 to about thirty revolutions of the main shaft 2|. More particularly, upon rotation of the main shaft 2!, gear 34 will drive gear 31, gear 38 will drive gear 3!, and due to the slight difference in the number of teeth in said gears 38 and 3|, the latter will have an angular velocity slightly higher than the former.
It is only this small increment in angular velocity which drives the gears 33 through the master gear 32; causing the rolls of finishing material to be Wound up very slowly on shafts 24, hence new material of said rolls is always presented at the lanes of operation against the brushes 28, thus accomplishing an extreme evenness of action on the surface 29 treated, and consequently extreme evenness of result.
This invention is capable of numerous forms and various applications without departing from the essential features herein disclosed. It is therefore intended and desired that the specific description and embodiment herein be deemed illustrative and not restrictive, and that the patent shall cover whatever features of patentable novelty exist in the invention herein disclosed; reference being had to the following claims rather than to the specific description herein to indicate the scope of this invention.
I claim:
1. In a surface finishing machine, the combina-- tion of a revolvably mounted main shaft, a frame member securely mounted on the main shaft, an unwinding shaft and a winding-up shaft mounted on the frame member in spaced relation parallel with the main shaft, a roll of surface finishing material carried on the unwinding shaft; the unwinding end of said roll being secured to the winding up shaft, a rotatably mounted gear, unsecured to the main shaft, adapted to rotate about the axis of the main shaft, a gear securely mounted on the winding-up shaft adapted to be driven by said first gear and means adapted upon rotation of the main shaft, to rotate said first gear in the same direction and at an angular velocity different than that of the main shaft, whereby the surface finishing material will be comparatively slowly wound up on the winding-up shaft.
2. In a machine as in claim 1 including a countershaft, a gear securely mounted on the main shaft, a gear of similar size securely mounted on the countershaft; one of said gears being adapted to drive the other, and another gear securely mounted on the countershaft adapted to drive the first gear mentioned in said claim; the said first gear and the gear last mentioned on the countershaft being of different size.
3. In a surface finishing machine, the combination of a revolvably mounted main shaft, a frame member securely mounted on the main shaft, an unwinding shaft and a winding-up shaft mounted on the frame member in spaced relation parallel with the main shaft, a roll of surface finishing material carried on the unwinding shaft; the unwinding end of said roll being secured to the winding-up shaft, a counter shaft, a pair of gears of equal size, in engagement, securely mounted, one on the main shaft and one on the countershaft, another gear securely mounted on the countershaft, a gear loosely mounted on the main shaft, in engagement with the second gear on the countershaft; the sizes of the last mentioned engaging gears being unequal, another gear loosely mounted on the main shaft and secured to the first loosely mounted gear, a gear securely mounted on the winding-up shaft in engagement with said second loosely mounted gear, whereby upon rotation of the main shaft, the surface finishing material will be comparatively slowly Wound up on the winding-up shaft.
