11 Claims.
This invention relates to a flaring device and more particularly to a tube-flaring device, although certain features thereof may be employed within 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.
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 resorted to in automobiles for establishing communication between the gasoline tank and carbureter serves only to illustrate the far-reaching uses of tubing. Tubing of this character is, connected to various instrumentalities 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.
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 flaring of the extremities so that an effective connection may be established. The joints'must necessarily be fluid-tight, and the effectiveness thereof depends largely on the type of tube extremity which engages the connectingunion or nipple. In consequence thereof, it is exceedingly important to provide a uniform and more or less perfect flare on the tube extremity so as to afiord a successful joint or tube connection.
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 therefor.
A still further object is to provide an effective and simple device for eifectively flaring the extremities of tubes without entailing as much labor or time as heretofore required with similar purpose tools.
v Still a further object is to provide a more efficient tube flaring device that is readily utilizable for tapering ends of tubes of varying diameter within apredetermined range.
An additional object is to provide an adjustable tube flaring device that has an adjustable flaring tool displaceable at predetermined positions for operation on tubes of different diameters without requiring any appreciable adjustment, care, or manual manipulation.
Other objects and advantages Will appear from the following description of an illustrative embodiment of the present invention.
1 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.
Figure 3 is an enlarged detail view of a pin taken substantially along line III-III of Figure 1.
The structure selected for illustration comprises confronting clamping members I and H which are preferably though not essentially of rectangularconfiguration so that one serves as a complement of the other with their adjacent surfaces l2 and I3 in confronting relation to serve as a clamping expedient for tubular con- -duits or other devices as will appear more fully hereinafter.
The clamping members l0 are preferably held in confronting assembled relation by means of guide pins l4 and I5 that project through apertures I6--ll and l8-I9 extending in axial registry through the extremities of the confronting clamping members l0 and H.
As shown, the apertures l6 and 18 extend partially through the clamping members Ill and H and their diameters are somewhat larger than the diameter of the pins l4 and I5 to accommodate coiled springs 20 and 2| in enveloping relation with the pins l4 and I5 for confinement in the apertures I6 and I8, thereby imparting a separating urge to the clamping members l0 and II.'
So as to maintain the clamping members I0 and II against accidental complete separation, the pins l4 and I5 have tapered heads 22 and 23 which occupy correspondingly shaped counter-sunk openings in the apertures I6 and I8 so as to communicate with the exterior edge surface 24 of the clamping member ID.
Consequently, the pins [4 and I5 are precluded from affording displacement of their enlarged heads 22 and 23 into the apertures l6 and I8.
' The enlarged portion of the apertures ll arid l9 are larger in diameter than the diameter of the pins H and I5 so as to present peripheral shoulders 25 and 26 which limit the separation of the clamping members Ill and H commensurate withthe length of the pins |4'and |5 that prefverably are provided with spring impelled detents 21 that extend to a circumference that is larger than the opening presented by the shoulders 25 and 26 that serve as a stop therefor.
Should it be desired to completely separate the members l9 and M, an unusual spreading force such as is. created by manually pulling the members l0 and H apart with a force'sufficient to comprss-thespring impelled detents -21 as such pass through the peripheral shoulders 25 and 26, affords their separation for cleansing, repair, replacement or other purposes. The assembly of the clamping members l0 and II in confronting relation so that their edge surfaces |2|3 are in adjacent contacting relation, is effected by merely inserting coiled springs 20 and 2| over the pins I4 and |5 and effecting their displacement through the limit shoulders 25 and 26 against the urge of the spring impelled detents 21 that preclude accidental separation after such become lodged in the openings |'||9.
It will be observed that the pins I4 and I5 are sufliciently long so as to afford the separation of the clamping members I0 and H responsive to the urge of the springs 29 and 2| for a. distancenecessary to incorporate tubular conduits that are disposed in and engaged by the confronting clamping members 10 and H. Semi-circular bores or recesses 28, 29, 30, 3|, 32, 33, and 34, in this instance seven, of difierent diameters are provided in the confronting edges I2 and |3 of the clamping members l9 and II.
It will be noted that each of the clamping members l0 and II have correspondingly sized semi-circular recesses 28, 29, 30, 3|, 32, 33 and 34 that serve as a complement of each other and provide the necessary encircling surface for most sizes of tubing within a range provided in any particular pair of confronting clamping action thereon by the confronting members I0 and II is effected by means of a bracket or yoke 31 having a horizontally disposed rectangular recess 38 provided therethrough in a lateral direction to receive the clamping members In and II along which the bracket or yoke 31 is displaceable.
An enlarged stud 39 is in engagement with a threaded aperture 49 extending through an edge 4| of the yoke 31 so that the conical extremity 42 of the stud 39 will be lodged in and engage correspondingly shaped depressions or cavities- 43 provided in the edge surface 44 of the clamping member The conical depressions 43 are positioned in alignment with the axis of the confronting semi- I circular recesses 28, 29, 30, 3|, 32, 33 and 34 so as to index the position of the yoke I directly in line with any selected circular opening defined by the confronting semi-circular recesses 28 to 34 after the stud 39 has been tightened responsive to manipulating the handle 45 that extends through the head 46 of the stud 39.
In order to flare the edge of the tube 35 that is engaged by any selected recess 28 to 34, the yoke 31 is provided with a vertically upstanding circular boss 41 that is interiorily bored as at 48 to communicate with an enlarged cylindrical opening 49 provided in the yoke 3'! for communication with the rectangular recess 38.
Consequently, the cylindrical opening 49 in the yoke 31 extends directly over the top surface of the confronting clamping members l0 and H so that a conical compressor 50 may be positioned thereon for manipulation by a shank 5| rotatively associated therewith through the connection afforded by a split ring member 52 that is lodged in confronting grooves 53 and 54 provided in the conical compressor 50 and its shank 5|, respectively.
The compressor shank 5| extends upwardly through the exteriorly threaded boss 41 that connects with a tubular member 55 which has a pin 56 extending transversely therethrough to engage the extremity of the shank 5|, thereby providing a fixed connection between the shank 5| and the tubular turning member 55. The turning member 55 has a handle rod 51 extending transversely over the upper extremity thereof so as to provide an effective handle that is movable in the turning member 55 within the limits of the handle extremities defined by the spring impelled detents 58 and 59 provided on the handle rod 51.-
It is to be noted that the turning member 55 has its interior bore 68 threaded to engage the exterior of the tubular boss 41 provided on the yoke 31 so that the rotation of the turning member 55 relative to the. boss 41 will raise and lower the conical compression member 50 to exert its flaring influence upon the extremity of the tube 35 within the limits defined by the inclined seats 6| which are provided in each of the semi-circular recesses 28 to 34 with a tightening stud 39 that exerts its influence on the confronting clamp members l0 and H which are clamped tight upon the tube 35 disposed in the proper confronting semi-circular recesses 28 to 34, inclusive.
Consequently, the compression member 50 Will be in axial alignment with the selected openings 28 to 34 to insure accurate and uniform flaring of the extremity of the tube 35 disposed therein and indexed by the tapering extremity 42 that is lodged in the correspondingly sized recess 43 provided in the edge 44 of the clamping member It should be observed that theyoke 31 has a circular opening 62 in its lowerregion to provide ample room for the insertion of the tubular conduit 35 within the proper engaging recess 28 to 34. ,Inorder to adjust the yoke 31 so that the compression member 58 is disposed over the selected tube engaging recess 28 "to 34 inclusive, it is only necessary to disengageithe conical extremity of the stud 39 from any one of the re cesses 43 and leave the compression member 50 above the confronting clamping members l0 and II so that the yoke 31 is completely displaceable along the clamping parts ||l| When the tube 35 is disposed within the proper recess 28 to 34, thestud 39 is tightened so as to securely hold the tube 35 for clamping engagement between the confronting members Ill-I I. Thereupon, the handle 51 is rotated to lower the compression member 50 against the interior oriflce of the tube 35 so as to flare its extremity against the tapered seat 6| of the selected recess 28 to 34, inclusive. I
The tube 35 is, thereupon, released or removed by releasing the stud 39 and permitting the clamping members Ill and II to separate within the limits of the pins l4 and I or the recess 38 provided in the yoke 31. The compression member 50 may be elevated to a position above the clamping members l0-H and the yoke 31 may be displaced to any recess 28 to 34 depending upon the diameter of the tube 35.
It will be apparent, therefore, that the yoke 31 need not be removed entirely from the clamping members l0 and II in order to allow the insertion of the tube 35 of any size within the range of the recesses 28 to 34 provided in the confronting clamping members l0l l.
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 or any features thereof, and nothing herein shall be construed as limitations upon the invention, its concept or structural embodiment as to the whole or any part thereof except as defined in the appended claims.
