110B MACHINE.

Application filed February This invention relates to new and useful improvements in shoe machines and more particularly to a machine for cutting or trimming the edge ofthe shoe sole.

With the machines now in use, it is necessary' to change the cutter for different kinds of work and the principal object of my invention is to provide a machine employing a plurality of cutters mounted on a rotating l carriage .and whereby the desired cutter may be instantly brought into cutting position by simply rotating the carriage a fraction of a revolution as required. In the accompanying drawings:

Figure 1 is a side elevation of a shoe machine embodying my improvements.

Figure 2 is a similar view, showing the drive shaft in extended position.

Figure 3 is an end view of Figure 1.

Figure 4 is a vertical transverse section, taken on line 4-4 of Figure 1.

Figure 5 is a fragmentary longitudinal section of the rotating carriage and associated parts.

Figure 6 is a horizontal section taken on line 6-6 of Figure 2, and Figure 7 is a vertical transverse section taken on line 7-? of Figure 2.

Figure 8 is a section on the line 88 of 30 Figure 2.

Referring to the drawings for a more par ticular description of the invention; A, designates the supporting frame, B the drive shaft, C the drive pulley, and D, the rotating carriage.

In carrying out my invention I provide a second shaft 1, which is mounted in the frame A below the drive shaft and held in stationary position by the locking member 2. The rotating carriage D is keyed to the shaft 1 and carries a plurality of cutters 3, 4, 5, 6, 7, and 8, of graduated size. I also provide an emery wheel 9 and a file 10. Each of the aforesaid cutters is mounted on the outer end of a horizontal shaft 11 journaled in the carriage D and provided at its inner end with one member as 12, of a clutch, the opposite member 13 of which is carried by the adjacent end of the drive shaft B. The emery wheel 9 is likewise carried at the outer end of a shaft 14, and the file at the front end of the shaft 15. The shafts 11, 14 and 15 are normally held in retracted position by the coil spring 16. The drive shaft B is also held in retracted positionby the coil spring 17. In practice, any one of the 6, 1926; Serial No. 86,495.

cutters or tools may be brought into play merely by turning the carriage D until the shaft of the corresponding cutter or tool is in line or registration with the drive shaft. The drive shaft is then extended or'projected by means of the handle 18 against the tension of the coil spring 17, and this operation likewise projects the aforesaid shaft 11 as indicated in Figure 2 when the desired cutting or trimming of the edge of the shoe sole may be performed. The handle 18 is carried by the sleeve 18, which is rotatable with respect to the shaft B, but stationary with regard to lengthwise movement.

The drive shaft is held in projected position by spring pressed bolt 19, the inner edge of which engages an annular groove or recess 7 20 formed in the outer end of the drive shaft. It will also be noted that the ball or knob of the handle 18 fits in the corresponding socket 20 in the handle or ball 21 which assists in holding the drive shaft in extended or pro jected position and the corresponding cutter or tool likewise in extended or projected position against the action or tension of the coil spring 17.

A sharpening wheel 22 is carried by the outer end of the drive shaft B and is used for sharpening the teeth of the cutters, as required.

From the foregoing description taken in connection with the drawings it is thought that the construction, operation and advantages of my invention will be readily understood without requiring a. more extended explanation.

Various changes in the form are proposed and minor details of construction may be made without departing from the principle or sacrificing any of the advantages of this invention. as defined in the appended claims.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a machine of the character specified, a supporting frame, a drive shaft mounted therein, a second shaft journaled in said frame below the drive shaft, a rotatable carriage keyed to said second shaft, a series of sleeves mounted on said carriage in a circle concentric to the second shaft, a series of cutter shafts each reciprocable in a respec tive sleeve for protraction and retraction and adapted for selective alinement with the first shaft, springs surrounding said cutter shafts and urging them to retracted position,

16 the first shaft, springs surrounding said cutter shafts and urging them to retracted position, clutch elements on the rear end of each cutter shaft and on the front end of the first shaft arranged for cooperative engagement, said first shaft being slidable longitudinally in the supporting frame to engage the clutch element on the first shaft with a respective clutch element on a cutter shaft and move the cutter shaft to protracted position, and spring means urging the first shaft rearwardly away from the carriage to disengage said clutches.

In testimony whereof I aflix my signature.

ALI HADI.
