by which the bracket may be rotated hori zontally, as well as moved vertically, for performing work at different levels and angles. A further object is to provide novel means for adjustably mounting the motor,'tha't ac- --tuates the routing and shaping tools, upon one of the sections or members of the bracket. A further object is to provide means for locking each of the sections of the bracket in various adjusted positions relatively to the adjacent sections, and for locking the motor supporting section indeendently of the other locking means. A "urther object is to provide means for accurately predetermining the angles at WhlCh the tools may be operated. Anda further object is to provide means for adjusting the motor and tool axiallyindependent of the bracket and the pedestal.
T attain these objects by the means set forth in the detailed description which follows, and as illustrated by the accompanying drawing, in which Figure l is a front side elevation of the complete device; showing by full and dotted lines the adjustable nature of the bracket that supports the shaping and routing machine. Fig. 2 is a top plan view; showing by full and dotted linesfa number of dif-.
ferent positions the router, as well as the bracket, may be adjusted and set for performing work at different points relatively to the pedestal. Fig. 3 is a broken side elevation, showing the motor of the full line position of Fig. 1 tilted at an angle in a vertical plane. And Fig. 4 is a detached View of the swivel member of the motor supporting section. h
In many of the shops and factories, the work assigned to my improved routers and shapers has become so varied, and much of said work requires such accuracy in the handling of the machines, that some convenient means for supporting the machine, in a man;
ner to permit universal movement thereof, have become imperative. I am aware that through wires 44 'certain facilities for adjusting, as well as for locking, the adjacent members to each other, such as must be provided in order to effect many of the different kinds of work required of machines of the class, as herein shown and described. Furthermore, in ad dition to the universal features, common to several of the older extensible supporting devices, it is necessary to provide means for adjusting and setting the machines, not only for predetermining accurately the depth of the cuts, but also many diflerent angles at which the routing or shaping tools mustbe operated. To this end, I have devised a novel universally operable bracket, which will now be described: 1
In the drawing, 2 represents a pedestal or standard having a relatively broad base 2, for rigidly securing the same to a work bench or table, as 2*. The body of the pedestal is preferably threaded throughout its length, as at 2. 3 represents a pair of adjusting nuts, which are carried by the pedestal, and may be operated separately or jointly, for adjusting parts carried by the pedestal. QWhen the nuts 3 are tightened against eachother they become locked against accidental movement on the pedestal.
4 represents a routing or shaping machine, comprising a high-speed electric mo-- tor 4', which is operatively enclosed in a stationary cylindrical casing 4*. The armature shaft 5 of the motor preferably extends beyond the opposite ends of the casing, as shown in Fig. 1. The motor may be driven by current derived from any source, as The external surface of the motor casing is shown threaded, as at i The lower end of shaft 5 is preferably threaded, and to this end may be attached anysuitable. chuck as 5', which holds the routing tool, as 5*. The motor 4 is preferably adj ustably held during the working periods, by means of a clampin member or holder, which comprises a split cylindrical body 6, that may be internallythreaded for adjustably receiving and supporting the mo.- tor. Adjacent the split, the body 6 is formed with similar spaced arallel lugs 6'-6* the said lugs being per orated and one of the perforations being threaded. The clamping of the holder to the motor is effected by a knurled screw 6*, in the usual manner. Di-
ametrically opposite the clamping lugs, the body 6 is formed with an integral relatively broad wing 7, which is preferably disposed in the plane of the axis of the motor, the said wing being perforated at 7, for pivotally mounting the holder, and said wing is also formed with a crescent-shaped slot 7 concentric to the said pivot opening. Beyond and substantially concentric to the slot 7* the wing is fitted with segmental scale 7 denoting degrees, said scale preferably reading from zero to about 45 degrees in opposite directions. The scale 7* is employed for accurately tilting or inclining the motor and tool 7 at different angles relatively to the adjacent supporting parts, as shown in Fig. 3.
The routing machine 4 is supported and adapted for universal movements over the work, as A, by a bracket, as 8, the said bracket comprising a number of sections, which are preferably pivotally joined to each other end to end, and the, remote sections of the bracket are respectively connected to the pedestal 2 and the motor-holder 6. The first section of the bracket comprises an irregularly-shaped body 9, the latter being formed with a hollow cylindrical portion 9, which is split at one end, as at 9, the portion 9 having a smooth bore for slidably receivin the threaded portion of the pedestal 2, an being adapted to be clamped to the pedestal, by means of a hand-screw 9, that enga es perforated clamping lugs 9, which are "isposed at the opposite sides of the split. The
opposite end of the section 9 is formed with a yoke 9 the arms of which are correspondingly perforated to receive a bolt 9, and below the yoke, the body 9' is formed with a radial boss or abutment 9.
The second section, of the bracket co1n prises a body 10, having at one end a per forated lug orear 10, which is received in the yoke 9? of section 9, and is held pivotally in lace, by the bolt 9*. Below the lug 10' the b are arranged to frictionally engage the boss 9, and are employed for adjusting the section 10 in a vertical plane relatively to the section 9. Ordinarily the contact between the nuts 10 and the boss is maintained by gravity. The opposite ortforward end of section 10 isbifurcated, and the arms of the fork are correspondingly perforated to receive a bolt 10". The lower arm 10 of the fork has a threaded perforation, to receive a clamping-screw 10 The third section, comprises a similar body 12, one end 12 of which is disposed in the fork of the member 10, the said end being transversely bored to receive the bolt 10 upon which the said section pivots. The bottom portion of the end 12 is formed with an integral disc '12, which normally bears ody 10 is fitted with nuts 10*, which upon the inner face of arm 10 of the member 10; the said disc being provided with a circular slot 12 through which the screw 10 is inserted and plays, and by means of which the section 12 may be held in various adjusted positions relatively to the section 10, as shown in Fig. 2. The forward end of the section 12 is similarly forked, and the arms of the said fork are also perforated to receive a pivot bolt 12 the lower arm 12 of the said fork being provided with a threaded perforation, to receive a clampingscrew 12 The fourth section of the bracket comprises two members 13 and 14, which are preferably swivelled together for independent movement relatively to each other. The
member 18 comprises av substantially cylin- I drical body having an enlarged vertically The bottom por forward end of member 13 is bored out axially, as at 13, the said portion being split, as at 13 and being formed with clamping-lugs 13, the clamping of said parts being effected by a screw 13. In order to render the said clamping more effective, the split portion of the barrel is preferably formed with a transverse kerf 13*, the latter being disposed between the lugs 13 and the pivot 12*. The member 14 is formed at one end with a reduced round portion 14', which pivots in the socket 13, and affords a desirable swivel action of said parts. The opposite end of the member 14 is flattened, and is arranged to directly support the wing 7, to which the said member is pivoted, by the pin 7*, which passes. through" a perforation 14*. Intermediate its ends the body 14 is provided with a threaded perforation to receive a clamping screw stood, by comparing-Fig. 3 with Figs. 1
and 2. The rbuter 4 may also be rotated together with the member" 14 on the swivel 14, which plays in the slot 7 of the wing, 'and by means of which the motor may be 14-13, as shown by the dotted lines 4* in Fig. 2.
