FRANK R. HARTSOCK, OF WARSAW, INDIANA, ASSIGNOR 0F ONE-THIRD TO CHARLES 0. i
DICKEY AND ONE-THIRD TO LEONARD E. DICKEY, BOTH 0F WARSAW, INDIANA.
TUBE-FLARING TOOL.
Application led April 5,
To all w71 om it may concern:
Be it known that I, FRANK R. HARTSOCK, a citizen of the United States of America, and a resident of Varsaw, county of Kosciusko, and State of Indiana, have invented certain new and useful Improvements in Tube- Flaring Tools, ot which the following is a full and clear specilication.
The object of this invention is to provide a simple tool for spreading or flaring the ends of soft-metal tubes commonly used in the lubricating systems of motor vehicles, the ends of the tubes being flared to facilitate coupling the ends of the tubes.
In the drawing- Fig. 1 is a `perspective View of my device;
Fig. 2 is a Side elevation, partly in section;
Fig. 3 is a sectional view on the line 3 3 of Fig. 2.
Referring to the drawing annexed, 5 designates a base member which is adapted to be held in a vise and provided with a rearwardly-extending arm 6, the rear end of this arm being. provided with an upstanding stationaryclamp-member 7 whose upper' edge is curved and provided with a series of semicircular grooves of different diameters for the reception of dilerentsized pipes. At one end, this clamp-member 7 is provided with an ear 8, to which is pivotally attached the swinging member 9 of the clamp, the arrangement of the hinge being such as to permit this swinging member to be thrown down on top of the stationary jaw 7. The under face of the movable clamping jaw is provided with semi-circular grooves adapted to register with the semi-circular grooves in the stationary member. A yoke-clamp 10 is provided for locking the clamp-members in position on the end of the tube placed in one of the grooves to thereby hold the tube against endwise displacement while its forwardly-projecting end is being flared.
For flaring the end ot' the tube, I provide a screw-rod 11 having a conical point 12 which, when the screw is advanced, will enter the tube and flare the end thereof. This screw-rod 11 is threaded through the upperend of a standard 13 which is pivotally mounted at its lower-end on a clamp-screw 14 tapped into the base 5. This manner of supporting the standard enables the point ot' the screw to be swung around so as to centrally enter a tube placed in any one of 1924. Serial No. 704,456.
the grooves in the clamp. That is to say, the pivot screw 14 is so located that when the standard is pivotally moved thereon, the point of the screw describes a curve coincident with the curve on which the tubeclamping grooves are arranged. In this way, the flaring tool may be quickly adjusted to cooperate with a tube placed in any one of the grooves, and, whether the tube be large or small, the conical point 12 will enter the same centrally and thus accurately flare the tube. After the llaring tool is adjusted properly with respect to the tube to be flared, the screw 14. may be tightened to hold the tool in position during the flaring operation. The flaring-screw is desirably provided with a handle 15,and `the swinging standard 13 is desirably provided with stop# lugs 16.
What I claim as new is:
1. Ina tool of the class set forth, a sup porting base having an upstanding stationary jaw, the upper face of this being curved and provided with a series of semicircular grooves of various diameters, a movable' clamp-j aw provided with a similar set of grooves, a daring-tool, and a standard for this flaring-tool pivot-ally mounted on the support to adapt the tool to be centered with respect to any one of the grooves in the clamp.
2. In a tool of the class set forth, a base, means thereony for clamping a tube, this means embodying a plurality of tube-clamping grooves of various diameters, a screw laringtool, and a holder for this tool and means whereby the holder may be adjusted to bring the point ot the flaring-tool into axial, alinement with any one of the aforesaid tube-clamping grooves.
3. In a tube-flaring tool, a base,- clamping `means for holding a' tube embodying a plurality of tube-clamping grooves arranged in an arcuate line, aitube-laring tool, an arm for supporting this tool, said arm being pivoted to said base, and a clamping screw for holding the arm inits adjusted positions, the pivotal point' of the arm being such that the point of the flaring tool may be adjusted to axially aline with any one of the tubeclamping grooves.
In testimony whereof I hereunto alix my signature.
