Application September 11, 1935, Serial No. 40,070 1 Claim. (01. 51-109) This, invention relates to shoe finishing ma- 30 to the motor housing 20. The casing 29 is chines. I provided with an air inlet 3| which communicates The general object of our invention is to prowith a conduit 32. This conduit 32 is U-shaped vide an improved shoe finishing machine by and is secured to the casing by screws 33. The 5 means of which the sole or other part of the shoe conduit 32 passes through the slot I2 and ter- 5 may be properly finished and wherein novel minates in a segmental housing 34 which is dismeans is provided for removing the material posed adjacent the abrasive member 21. This taken from the shoe. housing 34 has a top wall 35, a. bottom wall 36, Another object of the invention is to provide and an outer peripheral wall 31. The inner face an improved shoe finishing machine including 38 of the housing 34 is open. One end of the 10 an abrasive wheel with a novel suction member housing 34 is closed by the closure plate 39 which for removing the material taken from the shoe. may be held in place by the screws 40, but the A further object of our invention is to provide other end of the housing M is open. an improved mounting for the abrasive member In operation the machine is mounted on a base, of a shoe finishing machine. as described, and when the motor is operating 15 Other objects and the advantages of our inventhe rotor 28 produces a suction, creating a partion will be apparent from the following desoriptial vacuum in the conduit 32 and a partial vacution taken in connection with the following drawum in the segmental housing 34.

On the base II we show Preferably the abrasive member 21 is disposed a pair of brackets I3. Each bracket is L-shaped just below the plane of the bottom wall 36, also and includes a portion I4 which is secured by the exact position will depend upon the require- 35 bolts I5 to the base II.

By means of the slots I'I pose, and just above the abrasive support 25 in- 40 the vertical position of the pedestal I9 can be stead of as shown, and that in this construction 40 adjusted. The pedestal I9 supports a motor the length of the U-shaped conduit 32 would be housing 20 within which is an electric motor much inclined. which has an armature shaft 2I projecting from From the foregoing description it will be apone end and an armature shaft 22 projecting parent that We have invented a novel shoe finfrom the other end.
