UNITED STATES PATENT OFFICE.

Specification of Letters Patent.

Patented Mar. 8, 1921.

Application filed October 23, 1919. Serial No. 332,588.

cutting. A further object is to provide ameans for adjusting the cutting tool to any desired level and means for keeping the same at this level. These and other objects are accomplished by my invention, one embodiment of which is hereinafter more particularl set forth.

or a more detailed description of my invention, reference is to be had to the accompanying drawings, forming a part hereof in which--.

igure 1 is a longitudinal sectional view of a machine embodying m invention.

\ Fig. 2 is a cross section s owing the lower part of the machine,

Throughout the various views of the drawing, similar reference characters designate similar parts.

The shaper 1 is provided with a table 2 having a top 3, a support 4 and a base 5, all of which are preferably cast integral and the support 4 is bored true near its upper vided wit end to receive the motor 6 which has a vertically disposed armature 7 which is mounted on a thrust bearing 8 at its lower end and guided by suitable ball bearings 9 and 10 so that it always turns easily and runs true. a

The up er end of the armature 7 is proa number of washers 11 which are held by a nut 12 at the top and the bottom washer is provided with a protecting collar 13 which extends well over the upper bearing 10 and fully protects the same. At any convenient level, a cutter 14 is interposed between two of the washers 11, as shown.

To facilitate the removal of the motor 6,

or its insertion, the table 3 is providedwith.

a central opening in which rests the flanged plate 15 which has a central perforation through which extends the armature 7 and washers 11.

The support 4, near the lower end of the motor 6, is provided with hand holes which are covered with screw plates 16 which may be removed to permit an examination of the commutator 17 or brushes 18 of the motor 6. The support is also provided above a screw plate 16 with a slot 19 in which runs a nut 20 which is fixed to the motor 6 and proyided with a screw 21 which rests in a bearmg 22 which projects from the support 4 at the top of the slot 19. The upper end of the screw 21 is provided with'a bevel gear 23 which meshes with a second gear 24 on a shaft 25 which is provided at its other end with a hand wheel 26 and-is supported by bearings 27 which hang from the under surface of the table 3. By turning this hand whgel 26, the motor 6 may be. raised or lowere The motor 6 is connected to a cable 28 which passes through an insulating bushing 29 set in a, hole near the base 5. Through this cable electricity may be supplied to run the motor. Each side of the slot 19 is providedwith laterally extending ears 30 which are shown integral with the support 4 and these are connected by a clamping screw 31 which may be turned by a handle 32 so that the support 4 may be clamped firmly about the motor 6 by turning the handle 32 whereby the cutter 14 is put and kept at the proper level above the table 3.

' In view of the foregoing the operation and use of my improved shaper 1 will be easily understood. Assuming the parts as above described and electricity supplied through the cable 28, the armature 7 revolves at a. high speed with little power and when work is brought against the cutter 14, it may be sha ed in the usual manner. If the cutter 14 1s not at the right level, it may be adjusted as above described by the screw 21 and when in position, the motor may be clamped by the screw 31 and its connected parts.

While I have shown and described one embodiment of my invention, it is obvious that it is not restricted thereto, but is broad enough to include all structures which come within the scope of the annexed claims.

What I claim is:

1. A shaper with a support surmounted by a table, a cylindrical bore in said support with an openingat one side, a vertically disposed motor mounted in said bore and ada ted to fit therein with its armature exten in through the table, a cutting tool on sai armature, a nut extending through said opening and secured to said motor, a screw passing through said nut and means for turning the screw, whereby the motor may be raised or lowered.

2. A shaper with a support surmounted by a table, the support having a cylindrical bore, a vertically disposed motor slidably mounted in said support and adapted to fit said bore, an armature for said motor and means for mounting the same so that it will revolve concentric with the axis of the bore of the support and means for fixing; the motor at any desired elevation.

3. A shaper with a support surmounted by a table, a basefor supporting the support, a cylindrical bore in said base and a motor mounted in said base with a cylindrical exterior surface which fits said bore, an armature mounted concentric with the axis of said bore, means for elevating or lowering the motor according to the nature of the cut to be made by the shaper and the 1ooation thereof and means for fixing the motor in the base at any desired location.
