This invention relates to improvements in wood shapers and is directed to improvements in the efiiciency in operation thereof.

A primary object of the invention is toprovide novel means for mounting the cutter in order to eliminate any possible displacement thereof and to insure direct action by the motor-at all times.

Another importantobject ofthe invention is to provide means to retain the cutter elementdirectly on the drive means itself and'thus avoid the inconvenience and expense of Separatelyoperating connections generallyin use today with the accompanying loss in motion when the. operation of the device is begun, aswellas the additional elements used being subjecttornechpanicaljailure and replacement.

And another important object of the invention is to eliminate the usual.type -,of end-.thrust provided for motors innse today. and by the-use.

of a rotatable ball upon which the-..mo.tor-;spindle.

rests, attaining. the identical result obtained in the usual and more expensive motors now available.

Still another object of the invention is to provide means for adjustingthe height of j the work table by simple rotative movement of a hand wheel in connection withthesaidwork table.

With these features in view, the invention-con. sists of certain features of novelty in the. construction. combination and. arrangementof parts by-whiohsaid features andcei others, hereinaiter appearing, are effected eall aS:-f.ully.-;described with reference,- to the, accompanying drawings and more particularly ;pointed .outgin the appended claim.

In the drawings:

Figure 2 is a front elevation of the shaper of the invention, but disclosing a modified means for mounting the cutter head thereon;

Figure 3 is a horizontal view taken on the broken lines 33 in Figure 1;

Figure 4 is a rear end view of the shaper of the invention with certain parts being shown in sec tion;

Figure 5 is an exploded perspective view of the cutter and means for retaining the same of the embodiment shown in Figure 2;

Figure 6 is an enlarged vertical sectional view of the adjusting means;

Figure 7 is an enlarged view of the cutter and 2 theamounting means therefor illustrated in Figure-1 and Figure-B-isan end view of the cutter element.

:Referring to the figures, the wood shaper of the invention is indicated generally at it and includes a base H.- upon which an adjustable table support M is securedon a base plate retained on-base 1-2 by suitable means such as bolts t8; A-work table '20 is adjustably retained in position by a support plate 22 secured thereto by retaininggbolts 24 or the like. A cutter 28 is mounted and retained above table 26 in operative POSiti-OflyfiS willsoon be described.

MotqrflB-is retained on an upwardly tapering support 38 suitably'mounted on base l2 and is conneotedbywires 3-21to an actuating switch 3% and a source of current supply, not shown, in the; usual manner, thisforming no part of the invention. fMotor ZBincludes the usual motor spindle-"136' extending axially therethrough and retained in an upper bearing. or bushing 38 secured'inadjustable supportmeans i l at the up.- per end thereof and in a similar bushing is retainedfinacounterbored portion 44. of motorsupport -3fli It is to be noted at this point that the lower end of spin-dle; 36 does not .contain the usual endi thrust bearing provided in motors in use todamjbut instead: terminates in a straight shaft haaex ends nt a bea 6 w h n a ces Mijinthe supporttfl andseatsupona spindle ball Qtjretained on the base of" counterbore A l" and with nthebear ns .5 t ta th eo T us. it is readily apparent that a simplified type of motorhas been provigledand onewhich attains the identicalre lllts of other motors now in use withjtheelirnination.of. cost in the manufacture thereof. Theupperportionof spindle iijfi extending beyonjdjmotor 23 includes a sleeve its, spin-ale 3 fif,' an d, sleeve AB extending through suitable apertures'SU' and 52in supportplate 22 and work table 20, respectively. Sleeve i8 terminates at short distance below the upper extremity of spindle 36 and forms an annular seating shoulder 54. Spindle 36 terminates in a threaded section 55 where it projects beyond sleeve 48 in order to receive cutter heads 25 and locking means therefor thereon.

Referring to Figures 1 and 7, one form of cuter 26 is illustrated and includes an apertured annular ring 58 rotatably retained on spindle end 56 and seating on shoulder 54 of sleeve 48. Ring 58 includes a pair of oppositely disposed cutters 60 includingcutting edges 62 in a manner well known in the art. A cutter looking or retaining means 64 is axially bored throughout the length thereof and is rotatably received on spindle end 56 to seat on the upper extremity of ring 50 and thereby press it into non-movable position on shoulder 54 of sleeve 48, lock 64 being secured to spindle 36 by suitable set screw means 66. A modification in the construction of the spindle and cutter is illustrated in Figures 2 and 5, spindle 35 including a transverse slot 68 and cutter 26 containing a depending transverse flange on the lower extremity thereof to seat in keyway 68, thereby insuring additionally the non-slip relation thereof. Cutter lock 12 is similar in construction to lock 64, but different therefrom in that the axial bore therein terminates in the head portion thereof and does not extend entirely therethrough. Set screw 86 serves to retain lock '12 on spindle head 56.

The adjustable support includes a depending,

4 belt connections is eliminated and cutter 26 is directly driven from motor 28. Spindle 36 rotates freely on ball 46 and thereby eliminates the necessity for supplying end thrust bearings normally employed. When it is desired to adjust table 20, hand wheel I00 is rotated, thereby moving support in avertical direction until the desired height has been attained.

It is to be understood that the invention above described is not limited to the exact arrangement and combination of parts as described in the specification, nor is the invention limited to the exact details of construction as illustrated in the accompanying. drawings.

Having described the invention, what is claimed as new is:

- A Wood Shaper comprising a base, a pair of uprights rising "from the base and having upper transverse frame 14 secured integrally with the w J lower portion of plate '22 and containing depending legs 16, legs 16 including lateralaper tured guide or slideway sleeves l8 and a medial, laterally and downwardly bar 80 extending therefrom. Lateral braces 82 are provided for support member M, as is clearly seen in Figure 1. Guide sleeves I8 receive therethrough vertically extending support rods 90 suitably journaled at 86 at the lower extremity thereof, their journals 8'6 being welded or otherwise mounted on base plate [6. tremities of support rods 90 and serve as a stop means for the vertical adjustment of table support 22, bearings 88 being held in operative position by means of vertical support members I4 mounted on base plate I6. The bar 80 ter- 0 minates in a lateral apertured bearing 92, threaded internally to receive therein a threaded rod 94 mounted in counterbore 96 (Figure 6) and suitably welded thereto at 98 in hand wheel I00.

Hand wheel I00 includes a lower, axially counterbored base I 02, bore I04 retaining a vertical stud or key I06 extending from base plate I6 and thereby retaining wheel I00 in operative position. Thus, by rotating hand wheel I00, threaded rod 94 rotates to vertically adjust support plate 22, and as a consequence work table 20, this being possible by the engagement of slideway sleeves 18 with support rods 90. Bearings 88 stop the vertical movement of support 14 to prevent disengagement thereof from the retaining means. Motor 28 is also retained in position by a cross member 90 whose ends receive bolts I08 that are threaded in apertures the rear of support I4. 2

In use, the desired cutter head 26 is seated on the extending extremity 56 of spindle 36 and is retained thereon by suitable locks 64 or 12. Since spindle 36 extends through motor 28 and retains cutter head thereon, the necessity for providing auxiliary equipment such as pulley and Bearings 88 engage the upper exand lower lateral projections, each of said projections having a vertical bore therein with the bores in the upper projections being in registry with the bores in the lower projections, a pair of guide bars extending through the bores in said projections and paralleling said uprights, a horizontal table, a substantially U-shaped frame depending from the table and including a pair of vertical legs, vertical guide sleeves carried by said legs and slidable on said bars between said upper and lower projections, a horizontal crossmember mounted on and extending between said uprights, a motor supported on said base and also supported by said cross-member, said motor including a vertical drive shaft, said table having an opening receiving said shaft, a vertical stud rising from the base, a hand wheel having a hub, said hub having a recess receiving said stud, an arm inclining downwardly from the frame and having a horizontal extension at its lower end overlying the hand wheel, said extension having a threaded aperture therein, and a threaded rod fixed to said wheel and threaded in said aperture.
