One feature of my machine resides in the" utilization of a drive assembly or actuating mechanism that is'adapted for movement by the; shoe that isapplied toth'e polishing cloth of the The pressure of the'shoe against the polishing cloth may' thus be e'a'sily controlled by machine.

As a iurther' feature of this-part'of the invention the drive assembly is preferably piv-* oted, andis moved-about its' pivot'hy' the pr es sure of the shoe against'the' polishing cloth that is actuated by the" drive assembly.

As a further feature of the invention;- tha polishing cloth is actuatedby eccentricmeans secur'edto the ends of the'cloth; Preferablmtthe" ends of the cloth are secured to eccentric means rotating about the same axis, and with the" ends of the cloth" preferably secured te the eccentric means substantially 180 anart --relativel-y 1 to I the axis of rotation.

A f'urthe'r feature of the? invention" resides in the utilization of disks" for reciprocating the" polishing- 01cm, the: disks being mountedfor: ro tation about oneaxis withithe ends of the polish ing' cloth secured thereto as generally set forth above'. The disks serve to protect the cloth against abrasionand against destruction such aswould be probable with another type of op erating means;

;heutilization- 0f a yielding shoe su-pport orrfifi' atlB. lt isj' 'ofcourse obvious that the polishing-v 3 cloth I2 will be held yieldingly in its inverted bight, and that it will be possible to move the cloth at will against the resistance of the relatively light springs I4.

To the bottom of casing I9 there is secured one leaf H! of a hinge 29, the other leaf 2| being secured to a mounting plate 22 whereby the said mounting plate may pivot relatively to the casing I9. A pair of springs 23 rest between the mounting plate 22 and the bottom 24 of the casing for cushioning the plate, the springs being housed in shallow depressions 25 of the said bottom 24. A spring 26 is mounted about a headed pin 21 that is in guide relation to th plate 22, extending through a bore 22a in the said plate. Spring 26 presses against mounting plate 22 and tends to urge it to its position of Fig. 2, the mounting plate 22 being movable against the pressure of spring 26 and about its hinge 29 as will hereinafter be set forth. Pin 21 is preferably secured to the bottom 24 of casing I9 by threading it into the position illustrated best in Fig. 2.

Secured to the mounting plate 22 is the standard 28 of a drive assembly comprising an electric motor 29 and a reduction gear housing 39 within which there is contained the usual reduction gears operated by the motor 29 for rotating an actuating shaft 3|. It will be appreciated that the motor 29 together with gear housing 39 and shaft 3| will be rotatable as a unit with standard 28 on mounting plate 22 and about the pivot of hinge 29.

Secured to the shaft 3| are a pair of disks 32, there being one disk for each end of the shaft. To each disk 32 there is secured a cloth fastener 33, the construction of which is best illustrated in Fig. 3. Each cloth fastener 33 is pivotally and rotatably assembled to one of the disks by a screw 34 extending into a threaded bore of the disk, and is kept spaced from its disk by a washer 35. Each end of the polishing cloth I2 is formed with a loop 36 as best seen in Fig. 3 whereby to slip over an arm 31 that is formed as a part of each cloth fastener 33. Because of the nature of its construction, each arm 31 may be moved to open a space 38 for the ready removal or insertion of the loops 36 of polishing cloth I2. A retainer loop 39 is pivoted at 49 to each of the fasteners 33, and is adapted to move from the position of Fig. 3 into the position of Fig. 2 for holding the arm 31 in position to close the opening 39, and thereby maintain the polishing cloth I2 assembled to the cloth fastener 33. It, undoubtedly, is quite apparent at this time that the polishing cloth may readily be secured to the fasteners 33 and the disks 32, and readily removed for cleaning or renewal as the case may be.

It should be emphasized here that the disks 32 serve to actuate the polishing cloth as would mere eccentric arms, but the disks protect the polishing cloth so that it is not subjected to the same hazards as when actuated by arms, cranks, or the like.

For controlling the rotation of the electric motor 29 I utilized a push switch designated generally by reference numeral 45 and comprising a stationary contact 46 and a movable button 41.

The button 41 is adapted for depression by a foot treadle 48 against the pressure of a spring 49. The spring 49normally maintains the foot treadle 48 in its position of Fig. 2, with a screw 59 serving as a limit member. The treadle 48 is secured by a pair of screws to the upper surface of the box-like casing I9, and has sufiicient resiliency to flex from the position of Fig.

2 downwardly against the surface 52 of the casing I9 so as to move the push button 41 into contact relation to stationary contact 46. This, of course, excites the motor 29.

It will be interesting to note that the two cloth fasteners 33 are positioned substantially 180 apart relatively to the axis of actuating shaft 3|. In this way, the ends of the cloth will not only be reciprocated a distance equal substantially to the diameter of each disk 32, but will be moved longitudinally a similar distance. This means that the polishing cloth will have not only a reciprocating action but also a criss-cross action so as to impart excellent polish to a shoe. It will further be appreciated that the springs I4 will at all times maintain the polishing cloth l2 to form an inverted bight for a shoe that is applied to the treadle 48. In this way, a firm and positive movement may be imparted to the cloth I2, while allowing for the formation of the bight for the entry of a shoe. It will also be appreciated that the mere application of the shoe to the bight will effect a depression of treadle 48 so as to begin the operation of the motor 29.

For further protecting the cloth, the operating parts of the machine may be shielded by a sheet metal member 54 best seen in Fig. 4, but shown in outline in Fig. 2.

Those skilled in the art will further appreciate that in order to apply more pressure between the shoe and the polishing cloth, it will be necessary only to apply more pressure by the shoe against the cloth so as to rotate the drive assembly about hinge 29 against the resistance of spring 26.

For securely maintaining the casing of my invention against vibration relatively to the floor, I prefer to equip the casing with a series of vacuum cups 55, these vacuum cups functioning to hold the casing firmly in operating position, the pressure of the foot and any vibration of the machine acting to increase the effectiveness of the vacuum cups.

I believe that the object of my invention and v the operation thereof should be apparent to those skilled in the art.

I now claim:
