Application October 1,

1 Claim.

This invention relates to shoe repair machines, and has for the primary object, the provision of a device of this character which will render shoe repairing less tiring on the operator, in that the operator may remain in one position and readily bring the various motor driven tools into position for carrying out the various operations in repairing shoes. i

Another object of this invention is the provision of a single suction means which will emciently collect cuttings from all tools of the cutting and abrading types and deliver the cuttings to a single collecting device for emptying after the expiration of a given length of time.

With these and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention,

reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a side elevation illustrating the shoe repairing and finishing machine constructed in accordance with my invention.

Figure 2 is a top plan view illustrating the same.

Figure 3 is a sectional view taken on the line 33 of Figure 2.

Figure 4 is a sectional View taken on the line l4 of Figure 3.

Figure 5 is a detail sectional View showing the means of adjustably securing the split clamp.

Referring in detail to the drawings, the numeral 5 indicates a pedestal, including a vertically arranged post 6 on which is journalled a tool mounting 1 preferably in the form of a drum or of cylindrical shape. However, the tool mounting i may be of any other configuration and provides therein a chamber 8 open to the upper end of the post 6 which is hollow as shown at 9. A partition Iii is arranged in the post a limited distance above its upper end for closing the portion 9 of the post to the lower portion thereof. The hollow portion 9 of the post has an opening it to which is connected a suction fan 52 of a conventional construction driven by an electric motor I3. The suction fan i2 is equipped with an exhaust pipe I 4 which may lead to a collecting receptacle, not shown, or if desired, a conventional type of dust collecting bag may be connected to the fan [2 in lieu of the pipe Hi. Thus it will be seen that when the fan i2 is in operation suction will. be had in the chamber 8 of the tool mounting by way of the opening I l in the hollow portion 9 of the post.

1938, Serial No. 232,857

Mounted on the periphery of the tool mounting I are motor supporting brackets l1 carrying electric motors l6 and IS, the ends of the shafts thereof having secured thereon the different types of tools employed in shoe repairing and the tools which are of the cutting type or of the abrasive type have associated therewith guards ll to which suction pipes l8 are connected or form integral parts thereof. The suction pipes connect with the chamber 8 of the tool mounting and have located therein valves IQ of the damping type. The suction pipes which lead to the cutting tools of one of the motors [6 are connected to a single operating rod I9 which is provided with a handle 2i] and a projection 2!. The projection 2| connects or engages with an electric switch 22' for controlling the operation of the motor. The purpose is to close the switch when the valves are opened so as to set the motor in operation and when the valves are opened suction from the chamber 8 will draw therein the cuttings from the tools when the shoe is being repaired.

As shown further in Figure 2, one of the motors l6 has associated therewith only a single suction pipe and the valve thereof has connected thereto an operating rod 22 which also is adapted to control the switch 23' of that motor. out departing from the present invention, it is to be understood that the valve operating means may be varied, that is, the operating means may be arranged to operate one or more valves or a single valve. In either instance, it is to be understood that'when the valves are moved into open position the switches are operated to close the circuits to the motors and when the valves are moved into closed position the switches are operated to break the circuit to the motors. Further, it is to be understood that when one of the motors I B is in operation, the other motor H5 is left inoperative and the valves of this motor remain closed. so that all of the suction acts to take the cuttings away from the tool of the motor which is in operation.

Electric collecting rings 24 are mounted on and insulated from the tool mounting and surround the post as clearly shown in Figure 3, and are engaged by brushes 25 carried by a support 26 on the post and insulated therefrom. It is to be understood that the brushes 25 are connected in an electric circuit of any conventional type and also the electric motor [3 of the suction fan so that the electric motor l3 will be in operation Whenever one of the motors IE is in operation.

With- Carried by the tool mounting and surrounding the post is a split sleeve 21 equipped with a suitable adjusting medium 28 which will permit the sleeve to be brought into gripping relation with the post for holding the tool mounting against accidental rotation. However, the tool mounting may be freed for the purpose of rotation to bring the desired motor and its tools into a position adjacent the operator.

It is believed that the foregoing description, when taken in connection with the drawings will fully set forth the construction and advantages of this invention to those skilled in the art to which such a device relates, so that further detailed description will not be required.

Having thus described my invention, what I claim is:

A shoe repairing machine comprising a pedestal, a drum journalled on said pedestal having a chamber, electric motors mounted on said drum and having connected thereto shoe repairing tools, switches for said motors, suction pipes connected with the chamber of the drum and associated with the shoe repairing tools to receive cuttings, valves in said suction pipes, operating means for said valves and switches whereby on the opening of said valves said motors will be set in opera tion, and a suction means connected to the chamber of the drum.
