BENDING-MACHINE.
SPECIFICATION forming part of Letters Patent No. 736,834, dated August 18, 1903.
Application tiled August 16, 1902. Serial No. 119,893. (No model.)
To @ZZ whom it may concern.-
Be it known that I, CHRISTOPHER FLINN, a
'citizen of the United States, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented acertain new and useful Improvement in Bending Machines, of which the following is a full, clear, and exact description.
The object of this invention is to provide a machine for use in bending pipes or tubes, and especially parts of this kind that are furnished by car and locomotive builders as part apparatus suitable for carrying out the invention.
The table 1 is mounted upon suitable legs or standards 2, and one of its ends is grooved transversely with undercut grooves 3 4 5, and above the table is mounted a cylinder 6, having a stud or pivot 7, adapted to slide inthe groove 4, so as to provide for the adjustment of the cylinder to the work to be done. Stop lugs or clamps 8 and 9 are adapted to engage the grooves 3 and 5, respectively, and the cylinder in order to hold the cylinder when placed in any desired adjusted position. The piston-rod 10 of this cylinder is supplied with a former 11, herein shown as of the profile ot a segment of a circle and adapted to bend the blank on curved lines. Of course the former will be shaped to conform to the character of the work to be done.
I prefer to use air-pressure for operating the piston; butany other iiuid may be used, and I have shown the cylinder equipped for the use of air-pressure, the pressure being admitted to the rear end of the cylinder by a pipe 12 and admitted to the front end of the cylinder by a pipe 13, and these two pipes alternately act as pressure and exhaust pipes and for that purpose are connected with a threeway cock 14 of any suitable construction and receiving its supply from any suitable source through pipe 15.
16 is a head-block on the table rising above its surface, as shown more especially in Fig. 2, and made with or secured to the table. Against this head block are abutted the former'block or blocks 17 of the contour of the shaped article. Y
The blank to be bent is secured in any suitable way upon the table (as by pins 18, placed in holes 19 in the table) betweenV the former 1l and the former block or blocks 17, and pressure being applied to the piston its attached former is brought into contact with the blank and imparts to it the desired contour.
Other pressure mediums than air may be employed; but I have found that air is an excellent medium for use in this operation.
The pipes for controlling the pressure in the cylinder may be Wholly or partly flexible in order to admit of Jthe adjustment of the cylinder.
1. A bending-machine, for use in connection with ablank, comprising essentially a table provided with transverse grooves, a head-block thereon, and a pressure-cylinder mounted upon said table and pivotally secured in one of said grooves and adjustable therein transversely of the table, clamps to hold the cylinder in adj usted position, a piston in said cylinder, and a former carried by said piston and adapted to act upon the blank at that portion thereof adjacent to which it has been placed by the pivotal and transverse adjustment of the cylinder, to bend said blank into shape.
2. A bending-machine, having a table provided with transverse grooves, a pressurecylinder pivotally mounted upon said table and movable longitudinally in one of said grooves, clamps to hold the cylinder in adjusted position, a piston for said cylinder, a former mounted upon said piston, and means to secure the blank in position to be acted former actuated by said cylinder, and a headzo upon by the former, substantially as deblock on the table. scribed. In testimony whereof I have hereunto set 3. A bending-machine, having a table promy hand this 13th day of August, A. D. 1902. 5 vided with transverse grooves, a pressurei cylinder mounted upon said table and ad- CHRISTOPHER FLINN justably secured in one of said grooves,elam ps Witnesses: engaging the other grooves and the cylinder OHAS.
