For?rmly holding these two parts together in to loosen their draw, bolts. The work machining unit or attachment herein chosen as illustrative of any portable self - every swiveled relationship to which they may be- turned, there is sunken in the flat face of mounting ?ange 16 an annular slot 95 of T powered machining unit may be constructed like that disclosed in copending application, Serial 65 shape cross-section which accommodates the square heads of clamp bolts 96 whose threaded No. 474.650. >It will Vsu?ice here. to explain that this‘ machining unit'will ordinarily include a ends project forward and out of the mounting ?ange 98 of crank case 86~and thereat take ‘main'body portion such as crank case 86 in a . which there may be guided lengthwise the shank a 1 tightening nuts 91. The collar section 15 of the improved jointed 1 I ill, of a tool" holder 12 carrying/a broach 6| angle bracket occupies the space between the top 7 or other form of work cutting tool adapted to be reciprocated lengthwise by the running of power arm 79 and the bottom arm 80' of yoke section motor 98 and preferably at, various speeds'de l?and is of hollow block-like nature boredto termined by a variable speed power transmis- ’ v?t and adjustably embrace the fully; cylindrical sion such as stepped pulleys housed within cas 75 end of overarm 34. A mean portion of collar 2,404,661 6 5 section ‘I5 is bored oversize at 13 to avoid. having than is shown in ‘Fig. 2', this viéw'bei'ng vertically to nicely finish a needless extent of bearing sur face for contact with the periphery of the over arm; The wall of member ‘I5 is split at ‘I2 and provided with lugsv to receive two tightening bolts 'II which pass through clearance holes in the lug on one sideof split ‘I2 and which have threaded engagement with the lug. on the other side of the split. The lower lug in Fig. 5 also contracted to save space in the drawing. In the carries a slot spreading screw ‘ID in threaded en gagement therewith whose top end may thrust against the lug on the opposite side of the split position of-parts shown in Figs. 1 and 2the tool holder I 0 l'will reciprocate in a true vertical path either‘ at the location of tool 6| shown in full lines, or‘at‘the broken line location of such tool which is attained by adjustively shifting yoke 16 so as to spread the split and cause member 15 to reduce the tightness of its hug on overarm 34. Hinge bolts 8| pass with a clearance ?t respec tively through elongated slot ‘II inthe top arm 19 of yoke section 16' and through a similar elone 15 gated slot ‘I8 in the bottom yoke arm 80 ‘and have threaded engagement with hardened threaded bushings 82 lodged immovably in section 15. Thrust washers 89 separate the heads of hinge - bolts 8| from raised faces of bosses bordering around slots ‘II and ‘I8 on the outer surfaces of yokie arms ‘I9 and 80. Further features of construction of the jointed angle support bracket consist in the following. Fig. 1 shows that the smoothly ?nished?at-faced crotch ofyoke section ‘I6 is seated ?rmly in sur face contact with the smooth ?at-faced end 68 of collar section ‘I5. The exterior'of this collar section, on the opposite side of overarm 34, from section ‘I6 and its carried work machining unit to broken line position in Fig. 1. This is done by loosening the hinge bolts >8! so the yoke section may be shifted radially outward and swung past the corner'of the collar section ‘I5 as indicated in Fig. 3. Either in the full line or the "broken . line position in Fig. 1, crank case 86 bodily may ' be‘ swiveled about the axis of' trunnion 85 and carry the axis of cutting tool 6| to any desired angle‘ of inclination in relation to the work. These two means of adjustment coupled ‘with the ability of the collar section ‘I5» to itself swivel about overarm 34, as well as to slide lengthwise thereof when fastening bolts ‘II are ‘loosened, gives to any'self-powered machining 'unit sup ported by‘means of- my improved jointed hinge bracket full ability to be located and inclined in as many different ways and positions as, can be located and disposed the self-powered ma chining unit of the aforesaid patent and pend ing application even if the ‘overarm 34 itself be rotatively ?xed in turret 22. It is of course un 30 derstood that after any adjustive shifting of the ‘position of the machining unit, all holding bolts lugs 69 and split 12, is provided with three spaced seating pads orbosses 65, 66 ‘and 61 in triangu lar relationship whose flat faces‘are coplanar‘ and afford three-point ‘seating abutment for the will be thoroughly retightened to prevent acci dental disturbance of the thus established posi ?at crotch face of yoke section ‘I6 when the latter means of worm 93 and worm gear‘ 9| will at all tion of the machining unit... The turning of crank case 86 relative to the yoke section ‘I6 by time's'relieve the operator from having force fully ‘to lift or support‘ any heavy part of the section end 68 at one time, and the coplanar machining unit that hangs off‘ balance even bosses 65, 66, 61 at another time, ?rmly and de? nitely establish the self-powered machining unit 40 though retaining nuts 91 are loosened. In the .at the opposite limits of its exactly ninety degree appended claims'the face of ?ange 98 is some range of swinging movement about the‘common times referred to as'a mounting face while'the ~ ?ange-like head of yoke section ‘I6 is referred to axis of hinge bolts 8|. This axis preferably in is positioned as in Figs. 4 and 5. The'?at face of tersects the longitudinal axis of overarm 34 and as a head wall presenting a swivel seat for mat is perpendicular thereto. On the top and bottom 45 ing contact with such mounting face of ?ange exterior of collar section ‘I5 there are provided While as herein shown, the projected axis of annular thrust surfaces 64 raised in relief and trunnion 85 is coincident with the axis of over ?nished ?at and smooth to swivel in contact with arm 34 in Fig. 2, these axes could to advantage the flat smooth inside surfaces of yoke arms ‘I9 98. and 80; respectively. ' _ exterior of collar section ‘I5 which’ bulges outward ' - 1 for some purposes be so related that one is in ec centric relation to the other, in which case the - . Figs. 3 and 5 show that the ?at crotch surface which faces seating ‘pads 65, 66 and 61 is concave ly hollowed out at 63 to clear thegrounded convex somewhat between lower seating pad 61 and up per seating pads ‘35, ‘66. Fig. 3 shows that the ‘ crank case 86 in Fig. 2 would be adjusted about 55 a different center when frame 98 is swiveled in relation to'yoke section ‘I6 than when collar sec-l tion‘15'is rotated about overarm‘ 34. A greater variety of possible ‘positions for the self-powered elongated slot‘ 11 permits pulling‘ the yoke sec tion away from concentric relation to the col machining unit results. Many other modi?ca be the case if yoke section ‘I6 were limited to reasonable interpretation of the claims. tions of the precise shapes, sizes and relation ships of v the structures here disclosed will be lar section far enough to permit hollow 63 to clear the outer corner of the collar sectionwhile swing 60 recognized as possible of incorporating the use ful principles of this invention. Hence the patent ing the yoke section past it aboutthe hinge bolts 8|. Greater compactness of the jointed hinge tube granted will be understood as vconteinp'laté ing and intending to cover all variations of and bracket as a whole is thus made possible and less ‘ size and weight of material is required in its con substitutes for the particular embodiment herein struction without sacri?cing strength, than would 65 disclosed which come fairly within the broadest swinging about a ?xed hinge axis. " ’ The manner of operating the improved jointed attachment structure in a manner to incline the longitudinal axis, or the stroking direction, of the cutting tool 6| into any angular relationship to ' the work will for the most partbe obvious ‘from the foregoing description. ‘Ordinarily the work table I2 will ‘be set in lower position‘ relative to the'cutting tool BI by means of handles l3, I1 75 l.
