This invention relates generally to flaring machines and more specifically to machines for flaring end portions of tubular structures, the predominant object of the invention being to provide a machine of the type mentioned which is simple in construction and arrangement and is capable of performing its intended function in a highly efficient manner.

Fig. 9 is a perspective view of one of a pair of jaws which form parts of the improved machine of this invention.
In the drawings, wherein is shown for purposes of illustration, merely one embodiiment of the invention, A designates the improved flaring machine generally. The flaring machine A comprises an outer cylindrical housing 1, within which is disposed for, straight line movement, longitudinally thereof, an inner cylindrical member 2, the outer face of said inner cylindrical member contacting closely with the face of the bore through said outer cylindrical housing 1. The inner cylindrical member has formed in its wall at the top thereof a series of gear teeth in the form of a rack 3 with which mesh the teeth of a partially toothed element 4 that is mounted on a shaft 5, said shaft being supported by a pair of ears 6 which extend'upwardly from the wall of the outer cylindrical housing 1, at opposite sides of a slot 1', with the element 4 disposed between said ears. The partially toothed element 4 is provided with a recessed extension 7 which serves as a socket, and an end portion of an operating handle 8 is screwthreadedly received in said recess of said socket. The opposite end portions of the wall of said inner cylindrical member 2 are of less thickness than is the intermediate wall portion, as is shown to good advantage in Figs. 2 and 6, thus providing annular shoulders 2 and 2 at the points where the wall portions of reduced thickness meet the intermediate wall portion of full thickness.
Disposed within the inner cylindrical member is a drive quill 12 whose forward portion is of tubular formation, as shown at 12, said forward, tubular portion taken on:
ice
of said drive quill having a rear wall from whichexe.
tends rearwardly a shaft 13 which preferably, though not necessarily, is an integral part of said drive quill. The opening in the tubular forward portion of thedrive quill is eccentr'icallyarranged. The shaft 13 is provided withan annular shoulder 15 having an annular groove 16. formed therein in which a snap ring 17 is disposed. The
rear end of the outer cylindrical housing is. closed by a wall 18 which is secured in place by suitable fastening.
devices 18,, the ,wall 18 being provided with a center opening through which said shaft 13 extends. Arranged jin embracing relation with respect to a portion of said shaft 13 is a coil spring 19, one end of. which contacts 1 with said wall 18 and the opposite end of which contactsv with a snap ring 20 that'is disposed in an annular groove formed in the shaft 13. The shaft 13 is provided with a screwthreaded rear end portion 21 of reduced diameter on which is screwthreadedly mounted a multi-faced nut- 22, the various faces of said nut being. curved slightly as is shown at 22' in Figs. 2 and 6, for a purpose to be hereinafter set forth. y
The drive quill 12 is provided at its forward end with an outwardly extended annular flange 12, and disposed between said annular flange and the annular shoulder 2 of the bore of the inner cylindrical member is a needle bearing structure 23, the rollers of said needle bearing structure being in rolling contact with a portion of the circumferential face of the forward portion 12 0f the drive quill 12. Also, a ball bearing. structure is interposed between a portion of the shaft 13 and the inner wall of the rear end portion of the inner cylindrical housing 2, said ball bearing structure being disposed with l its inner raceway located between the annular shoulder 15 of shaft 13 and the snap ring 17, and with the outer raceway of said ball bearing structure 24 located between the annular shoulder 2 of the inner cylindrical housing 2 and a snap ring 25 which is located in an annular groove formed in the wall of said inner cylindrical housing 2. Because of the use of the needle bearing structure 23 and the ball bearing structure 24, it 'is' obvious that the drive quill 12 is supported for free, substantially frictionless, rotation with respect to an inner Disposed within the bore of the forward portion 12 of the drive quill 12 is an eccentric sleeve 26 which .is provided with an outwardly extended annular flange 26.
in its wall an annular groove 27 and a screwthreaded member 28 is screwthreadedly disposed in a screwthread? ed opening 28 formed through the wall of the forward portion 12 of the drive quill 12, said screwthreaded'i.
member 28 having a smooth extension 28 which extends into said annular groove 27 of the eccentric sleeve 26. Arranged within the bore of the eccentric sleeve 26 is a spindle 29 which is provided with a tapered head 29' at its forwardend portion, said spindle 29 being provided, adjacent to its opposite end, with an annular groove in which is disposed a snap ring 31 (Fig. I
6). The spindle 29 is supported for free rotation within the bore of the eccentric sleeve 26 by a pair of needle bearing structures 32 which are interposed between portions of said spindle and portions ofthe bore of the eccentric sleeve 26, as shown to good advantage in Figs. 2 and 6. As shown in Fig. 6, the snap ring 31 overlaps the rearmost of the needle bearing structures 32, and the rear end of the spindle 29 is provided with a recess 33 in which is disposed a ball 34, a portion of said ball projecting from said recess and contacting with a hardened metallic insert 35 which is fixedly located in an opening formed.
