more particularly to a tube-flaring device, al-

though certain features thereof may be employed with equal advantage for other purposes. It contemplates more especially the provision of a portable device for flaring the tube extremities Without requiring any appreciable equipment or special facilities. A Y

There are numerous occasions for flaring the extremities of tubes in that replacements are frequently occasioned in automobiles and other installations. In fact, the copper tubing re- `storted to in automobiles for establishing communication between the gasoline tank and carf. bureter serves only to illustrate the far-reaching uses of tubing. Tubing of this character is connected to variousinstrumentalities by a union or threaded nipple which is mounted thereon for turning relative to a flared tube extremity serving to'retain the nipple against removal. p There are numerous occasions for replacing such tubes or inserting a new portion therein, and-in consequence thereof it is necessary or at least highly desirable to enable the aring, of the extremities so that an effective connection may be established. The joints mustnecessarily be fluid-tight, and the effectiveness thereof depends largely on the type of tube extremityvvhich engages the connecting union or nipple. In consequence thereofy it is exceedingly important to provide a uniform and more or less perfect flare on the-tube extremity so as to afford a successful joint or tube connection. p y

One object of the present invention is to simplify the construction and improve the operation of, devices ,of the character mentioned.

Another object is to provide an improved tool for flaring the extremity of tubes and similar devices.

Still another object is to provide a novel device for flaring the extremity of various sized tubular conduits.

A further. object is. the provision of a simple and effective portable `device for flaring the extremities of tubular conduits so as to afford a fluid-tight connection therewith.

A still further object is to provide an effective and; simple device for flaring the extremities of tubes, without entailing much labor or time.

Other objects and advantages Will appear fromthe,-folloWing `description of an illustrative embodiment of the present invention.

In the drawing:

Figure 1 is a plan View of a device embodying features of the present invention,

Figure 2 is a sectional view taken substantially along line II--II of Figure 1, and

Figure 3 is a sectional view taken substantially along line III-III of Figure 2.

The structure selected for illustration com- `5 prises a circular body member I0 which is preferably split into half-sections I I and I2 which are complemental to each other for contact along their adjacent surfaces I3. Threaded studs I4, in this instancetwo, are anchored in the bottom 1z0 section I2 for projection through correspondingly-shaped aperatures formed in the top section II. Wing-nuts I5 threadedly` engage the studs ,I4 toretain the half-sections II and I2 in association for selective contact responsive to I5 turning tight the Wing-nuts I5 in the customary manner. A pin I6 is anchored in the bottom section l2 to any suitable radial position so as to register with aperture II formed in the top section II, thereby guiding the half-sections II 20 and I2 for accurate registry.

A plurality of bores Il', I8, I9 and 20, in this instance four, are provided radially in the body member I0 so that the diametral line thereof corresponds with the contacting surfaces I3 of 25 the half-sections I I and I2, thereby placing half of the bores Il', I8, I9 and 20 in both sections II and`I2 for` complemental association in longitudinal alignment. With this arrangement, the bores Il, I8, I9 and 20 are of sectional formation 30 for the reception of tubular conduits 2|.

In consequence` thereof, the bores Il, I8, I9 and 2lir are of various diameters to correspond with the standard sizes of tubes that are generally used-in different situations occurring in commerce, and these are in

axial alignmentwith bores

22, 23, 24 and 25, respectively. The

lattermentioned bores

22, 23, 24 and 25 are of identical size/to receive a cylindrical impacting device 26. The impacting device 26 is slightly tapered and has` a nurled extremity 2l to enable the convenient manipulation and handling thereof. As shown, the impacting or hammer device 26 terminates in a conical tip 28 which corresponds in 45 inclination and configuration With tapered seats 29 formed at the inner orifice of the bores Il', llll, I9 and 2E! as delinedby a circular aperture 2liv provided in the body member I0 so as to be in alignment in both half-sections II and I2. Infshort, the-tubular conduit bores Il', I8, I9 and 20- are interrupted with respect to their correspondingly aligned impacting device receiving

bores

22, 23, 24 and 25 so that any one of these sets of bores may be utilized at selective times to flare the extremity of correspondingly sized tubing 2l.

The tubing 2l is placed in a correspondingly sized bore, in this instance bore I8, with the Wingnuts l5 sufciently loosened for the free reception thereof. The tubing 2 IY projects beyond the inner orice of the bore I8 for a slight distance commensurate with the seat 29 thereof, and the Wing-nuts are thereupon tightened to securely clamp the tubing 2l. The impacting device or hammer device 26, thereupon is inserted in the bore 23 which is in alignment with the bore I8, and contact is established With the mouth of the tubing 2|. `A hammer or other tapping device is utilized to strike the extremity 3l of the impacting device 26 so as to deform the extremity of the tubing 2l by daring such to correspond with the confronting impacting tip 28 and bore seat 29. As a result, a flaring extremity 32 is provided on the tubing 2| so that a nipple or other securing Ydevice may be placed thereon for contact and retention by the flaring extremity 32 thereof. In

this manner, a dared extremity may be formed on any tubing and the device is portable so as to be utilized in any situation. To enable the more convenient handlingof the body member I0, the exterior periphery 33 is nurled in the customary manner. It is to be noted that any number of bores may be provided in the body member I0, and the device may be utilized in a very effective and simple manner Without entailing much labor or time. v

Various changes may be made in the embodiment of the invention herein specifically described Without departing from or sacrificing any of the advantages of the invention as dened in the appended claims.
