A bolt 7 passing through the

lugs

6 and 7 pivotally connects the frame 9 to the base. The usual member 14 is utilized for running the member 11 and thus the jaw 10 up and down to and from the stationary aw 5. This structure S,15134;d per, sedoesinotconstitute my uwen. [s lli. e; .A

Re erring for the moment more particularly to Figs. 1 and 8 to 11 inclusivefitwill be noted that the portioniofithebase-in .which the station ary jaw 5 is mounted is extended as shown at 15 and provided with a transverseslot 16 and a proj ection1=7 rovlding Shqulder 18.

T hegdog is provided with a shoulder 24 Breeding all; abutment adapted t0 enses@ eneath'and,behind,the.shoulder 18 to secure t e frame to the'base in the ordinary manner. 'n f Tnnthe ,rear A .ofthe gplanelvrof .cooperation of theestationary and. movable aws, that is, to thefrear of the vise, a bolt or lthe like 25.se uredrin; the .base,pivotally. mounts one end 25 ofA an arm 27 andalso an angle bracket 28 gr; swinging .movement thereabout. The vertical side ofthegangle bracket is drilled forgthe Ireception of a pivot-bolt 29 on which an arm 31 of a pipe bending die member havimgHai-.head 32 ispivotally mounted. From the foregoing it will be appreciated that the arm 27 may beswungabout .the pivot provided bythe bolt 25 in one plane and that the die member .may be swung about both the pivot 2 5. and the pivot 29 so-that it may have substantially .universal movement with respect -tothe base. i

L. arm 27 isprovided with upst-anding lug portions 334 and 34 providing between them a necess 35 adapted toreceive a pipe or the like 'and'the recess 35 is arranged so that when vth e,arm.27 is in the position shown in Figs. 2 and .3;'it will align` withthe opening between -the jaws of the vise. This arrangementisa decided aidin securing the pipe 36 against skewingwhen'its outer end is being )gent aroundthe die head 32 and in order to reinforce the arnu 27 when in the position shown in Figs. 2 and 3, a 'lug 37 is cast or otherwise secured to the base for abutting 'en-` gagement with it. The arm 27 lmay be swung-.fout of. the way when large sizes of pi ,e are beingroperated upon.

' he construction of the die head is shown lnre clearly.in-Figsl.`5 6 and 7, from which it will be noted that it is of substantially course, of greater length than the surface 38,

since the larger the pipe the greater must be the radius of curvature ofV a bend madetherein. The arm 31 o f thediememberisradapted .to be disposed in the opening provided between the leg or arm 19, the jaw 5 and the extension=15 and tobe secured against movement in the direction of its length by an arc- -ii'at-e lug formed integral therewith and adapted to slide laterally of the vise in an 'areuatel groove 43 formed in the top of the extension 15,.l Y Shouldithe

pivots

25 and 29 becomesomewhat worn or loose, the lug 4t2 engaging' in thek groove 43 will hold the die and memberv against` displacement.

In Fig. l13 I have illustrated geoinetrically the formation of the die headfrom which it will be noted that the inner curve 38 is generatedby the circular movement of an are of acircle a at the end of the radius Ziff about the ,point c ina direction transverseto the plane of the circle ofthe arc with the chord of thegarcdisposed farthest'from said point 02, while the interiorsurface of one side wall of the channel, i. e., the vsurface 39 is generated by the like movement and disposition of the arc of a. circle w movino' at the end. ofy a radiusiy about a point". a. Of course, is greater than a, y is greater than b and the points c and zl are adjacent one another on the same side of the

surfaces

38 and 39, that is, to the rear thereof, but are not coincident. From this description. it is believed that the relationship of the

curves

38 and 39 of the die head may readily bel understood. It will benoted that the

curved surfaces

38 and 39 are substantially separatedat one end of the die head, but merge finally at the end of the die headedjacent the box of the vise, thus forming' the channel side walls of two portions, an upper or exterior portion and a lower or interior portion of different curvatures extending for substantially the full length of the channel surface.

lt will thus be apparent that the die meinber is adapted to receive and bend pipes of different diameters when the pipe is held between the jaws and by the member 27, and the die member is secured in position between the arm 19 ofthe frame and thebase of the vise. Since each size of pipe when bent betweengthe points of tangency A and B, as shown in Fig. 3, utilizes a-greater length of pipe than the perpendicular-distance from either'point of tangency-A or B to the other, due allowance must be made when ai'm to said base,vso that saidihead may be swung into and out of said position.

3. In combination with .a pipe vise having a pair of jaws one ofwhich is movable for receiving and clampinga pipe betweenztliem, a pipe bending attachment having ahead `adapted to be disposed adjacent the opening between said jaws at one side thereof,"and means on the other side of said jaws pivotally mounting's'aid head so that said head may be s wungfrom one side of` said jaws to the other.
