The plurality of securing components 144 may include spring-loaded components that provide securing of the rotary compartment drum 108.

(34) The plurality of securing components 144 may include a plurality of springs 146 and a plurality of balls 148. The location of the circular groove 150 and the plurality of securing components 144 with respect to the rotary compartment drum 108 may differ in various embodiments of the oscillating spindle sander assembly 102. Specifically, the combination of components including the circular groove 150 and the plurality of securing components 144 may be located on the top, in the middle (on an internal cylinder surface), and on the bottom of the rotary compartment drum 108. In every location, two example embodiments are provided, in one of which the circular groove 150 may be arranged on the rotary compartment drum 108, while in another example embodiment, the circular groove 150 may be provided on the coupling part (i.e., the resting member 136, the oscillation generator 112, or the base 106).

(35) FIG. 1, FIG. 2A, and FIG. 2B illustrate an example embodiment, in which the circular groove 150 is located on the top of the base 106 and the plurality of securing components 144 is arranged on the bottom of the rotary compartment drum 108.

(36) The rotary compartment drum 108 may further include a plurality of recesses 142 distributed along the bottom surface 140 of the rotary compartment drum 108. The rotary compartment drum 108 may further include a plurality of securing components 144 placed in the plurality of recesses 142. The plurality of securing components 144 may include a plurality of springs 146 and a plurality of balls 148. The plurality of springs 146 may be placed into the plurality of recesses 142 in the bottom surface 140 of the rotary compartment drum 108. The plurality of balls 148 may be placed on the plurality of springs 146 in the plurality of recesses 142. Accordingly, a spring 146 and a ball 148 may be inserted into each recess 142.

(37) The base 106 may include a top surface 160 facing the rotary compartment drum 108. The rotary compartment drum 108 may include a bottom surface 140 facing the base 106. The bottom surface 140 of the rotary compartment drum 108 may be in contact with the top surface 160 of the base 106. The base 106 may include a circular groove 150 located on the top surface 160 of the base 106. The plurality of securing components 144 may sit on the circular groove 150 formed on the base 106.

(38) The oscillating spindle sander assembly 102 further includes a motor and drive unit 152. The motor and drive unit 152 may be disposed in the oscillation generator 112 and may be configured to provide rotation and oscillation of the drive shaft 118 of the oscillating spindle sander 104.

(39) FIG. 2A is a partial view A of FIG. 1 showing the circular groove 150 of the oscillating spindle sander assembly 102, according to an example embodiment. As shown in FIG. 2A, the base 106 may further include one or more dents 202 may be made in the circular groove 150. The one or more dents 202 may be evenly or unevenly distributed along the length of the circular groove 150. The one or more dents 202 may be deeper than the circular groove 150. In an example embodiment, the one or more dents 202 can have the shape of a hemisphere.

(40) In some example embodiments, one or more holes may be provided in the circular groove 150 instead of the one or more dents 202.

(41) The plurality of securing components 144 may sink inside the one or more dents 202 of the circular groove 150 and push the rotary compartment drum 108 away from the base 106 and toward the resting member 136. Specifically, with a securing component 204 supported by the circular groove 150, the rotary compartment drum 108 is pushed away from the base 106 and toward the resting member 136 of the oscillating spindle sander assembly 102.

(42) FIG. 2B is a partial cross-section view B of FIG. 2A illustrating a dent 206 of the one or more dents 202 and a securing component 204 that rolls on a dented surface 208 of the circular groove 150, according to an example embodiment. The dent 206 may have a bottom side 210 deeper than the circular groove 150.

(43) The rotary compartment drum 108 slides on the oscillation generator 112 of the oscillating spindle sander assembly 102, so the rotary compartment drum 108 rotates smoothly around the oscillation generator 112. Upon rotation of the rotary compartment drum 108 around the oscillation generator 112, a securing component 204 of the plurality of securing components 144 may rise out of a first dent of the one or more dents 202, roll along the circular groove 150, and sink inside a second dent of the one or more dents 202. Accordingly, with the rotation of the rotary compartment drum 108, the securing components 204 roll on the circular groove 150 until one of the securing components 204 sinks inside the dent 206 to hold a certain position of the rotary compartment drum 108. Rotating the rotary compartment drum 108 further forces the sunk securing component 204 to rise out of the dent 206 and continue to roll on the circular groove 150. The rotation of the rotary compartment drum 108 includes rotation of the plurality of storage compartments 110 around the oscillation generator 112.

(44) In an example embodiment, only one dent 206 may be provided in the circular groove 150 but a plurality of securing components 144 may be provided in the plurality of recesses 142. With the rotation of the rotary compartment drum 108, a first securing component 204 may rise out of the dent 206, roll along the circular groove 150, and the second securing component 204 next to first securing component 204 may sink inside the same dent 206 upon a certain degree of rotation of the rotary compartment drum 108.

(45) In an example embodiment, when sunk in the dent 206, the securing component 204 may contact the bottom side 210 of the dent 206. Moreover, when sunk in the dent 206, more than a half of the height of the securing component 204 may be out of the dent 206. This may allow the securing component 204 to rise out of the dent 206 upon exerting the force on the rotary compartment drum 108 in order to rotate the rotary compartment drum 108.

(46) The rotation of the rotary compartment drum 108 includes rotation of the plurality of storage compartments 110 around the oscillation generator 112. Specifically, the plurality of storage compartments 110 are disposed along the circumference of the rotary compartment drum 108 and, when the rotary compartment drum 108 rotates around the oscillation generator 112, the plurality of storage compartments 110 also rotate around the oscillation generator 112 of the oscillating spindle sander 104. The rotation of the rotary compartment drum 108 around the oscillation generator 112 may include one of a clockwise rotation and a counterclockwise rotation. Accordingly, the rotary compartment drum 108 may be rotated clockwise or counterclockwise around a vertical axis 154 of the oscillating spindle sander assembly 102.

(47) FIG. 3, FIG. 4A, and FIG. 4B illustrate an example embodiment, in which the circular groove 150 is arranged on the bottom of the rotary compartment drum 108. As shown in FIG. 3, the base 106 may include a plurality of recesses 142 distributed along the top surface 160.
