The embodiment of the invention chosen for the-purpose"of-illustration' comprises a bed or work rest l-having adjustable clamping jaws 2 and 3 forholding a stereotype cut or the like W in fixed position. An ar'm 5 pivotally mounted on one end of the work rest supports a second armfi for pivotal movement about its free end, the arm 6 being provided with an'exten'sion or operating handle 8',
the end'of which is freely 30 sligableover a-'rai1'9 mounted on one end of the be I In accordance with the present invention the entire driving unit or operating mechanism, designated generally by thenumeral 10, is mounted 5 adjacent to the'end'ofarm (Sand is universally: movable in-a fixed plane relative to the work rest 1. As shown in Figs. 2 and 3, the drivingunit comprises a bracket 11 which is rigidly secured tothe arm -6- in any suitable manner, as by bolts 12. The bracket 11 is provided with dovetailed flanges 14 and 15 defining a slideway, and an internally threaded socket member 16 intermediate the flanges. A high speed electric motor 20, controlled by a switch 20 (Fig. 1) carried by the 5 leads supplying current thereto, is supported by the bracket 11 and its casing is provided with dovetailed guide members 22 and 23 (Fig. 2) which slidably engage within flanges 14 and 15 respectively, there being a machine slide 24 interposed between the guide 23 and flange 15 against which set screws 25 take to vary the fit of the guides in the slideway.
Integral with the motor casing 21 and intermediate the guides 22 and 23, is a lug 2'7 having a cylindrical bore coaxial with the socket 16.
A screw shaft 28 is journaled in the bore of lug 2'7 and its threaded end 29 is received by socket 16. The opposite end of the shaft 28 carries an elongate collar 30, one end of which engages the arouting machine emlug 27 and its opposite end engages an annular boss 31 carried by a hand wheel 32 which may be keyed or otherwise secured to the shaft 28. Rotation of the hand wheel 32 in one direction or the other causes the motor and associated mechanisms to move toward or away from the work rest, thus providing means for accurately adjusting the position of the operating mechanism relative to the work W.
Integral with the opposite ends of the motor casing 21 and in circumferentially spaced relation to the screw shaft 28 are vertically aligned socketlike brackets 35 and 36, which, as shown in Fig. 4, receive anti-friction bearings 37 and 38 respectively, the latter being held within the lower bracket by the shoulders on an annular cover member 39 which is secured to the bracket 36 by screws 40. A shaft 45 having an axial bore is journaled in bearings 37 and 38 withits ;ends projecting beyond the brackets 35 and 36. Adjacent to its upper end the shaft 45 carries a small gear 46 disposed within the upper end of the socket-like bracket 35 and meshing with a larger driving gear 47 disposed within a housing 50 integral with the upper end of the motor casing. As shown in Fig. 4 the housing 50 may be provided with a cover plate 51 having an offset portion providing a closure for the upper end of the bracket 35. The driving gear 47 is keyed or otherwise secured to the shaft of the motor 20.
The lower end of shaft 45 has an enlarged bore terminating in a conical-shaped throat which receives a drill chuck 52 for holding a routing tool T. A spindle 56 disposed within the bore of shaft 45 carries a hand wheel 57 on its upperend, the lower end of the spindle being threaded to engage the threaded bore of chuck 52, as shown in Fig. 4: As the hand wheel 57 is rotated in one direction or the other, relative to the shaft 45, the lower end of the chuck is forced toward or away from the throat of .the shaft, thereby tightening or loosening the grip of the chuck on the tool T. Suitable means may be provided for conveniently holding the shaft 45 against rotation while tightening or loosening the chuck, and to this end a hand wheel 60 may be pinned or otherwise fastened to the upper end of shaft 45 intermediate the gear 46 and the hand Wheel 57, as shown in Fig. 4.
In operating the machine the routing tool T is first inserted in the chuck 52 and firmly secured therein by turning the hand wheel 57 while holding the shaft 45 against rotation by means of the hand Wheel 60. The arm 6 is then swung into operative position relative to the stereotype cut W and the entire unit 10 is vertically adjusted to the proper operating level by means of the hand wheel 32. The current may then be turned on and the routing operation carried on in the usual manner.
While I have shown and described one desirable embodiment of the invention, it should be understood that the present disclosure is for the purpose of illustration only, and that various changes and modifications, such, for example, as directly connecting the tool holder or chuck to the shaft of the motor, as well as the substitution of equivalent elements for those herein shown and described, may be made without departing from the spirit and scope of the invention as set forth in the appended claims.
I claim:
1. In a routing machine of the type having a work rest and a supporting member universally movable in a fixed plane relative to said rest, an operating mechanism comprising a bracket fixed to said supporting member and having means defining a slidewa guide members movable in said slideway toward and away from said work rest, an electric motor supported by said guide members and movable longitudinally of said slideway, a screw shaft associated with said guide members and bracket for moving said motor toward or away from said work rest, an elongate driving spindle offset relative to the shaft of the motor and journaled adjacent to its ends in bearings secured to the casing of said motor, a rotary tool holder secured to said spindle, and transmission mechanism connected to said motor shaft and spindle for driving the latter at an increased speed relative to the motor shaft.
2. A routing machine of the type having a work rest and a supporting member universally movable in a fixed plane relative to said rest, an operating mechanism comprising a bracket fixed to said supporting member and having means defining a slideway, an electric motor having guide members secured to its casing, said guide members being movable along said slideway toward and away from said work rest, a screw shaft associated with said guide members and bracket for moving said motor toward and away from said work rest, an elongate driving spindle offset relative to the shaft of the motor and journaled in bearings adjacent to its ends, a rotary tool holder secured to said spindle, and transmission mechanism connected to said motor shaft and spindle for driving the latter at an increased speed relative to the motor shaft.
