G MACHINE.
SPECIFICATION forming part of Letters Patent No. 361,487, dated April 19, 1887.
Application filed January 28, 1887.
To all whom it 11mg/ concern.-
Be it known thatI, GEORGE B. BRoWNsoN, of North Springfield, in the county of Greene, and State. of Missouri, have invented a new aud Improved Pipe-Bending Machine,ofwhich the following is a full, clear, and exact description.
rlhe object of my invention .is to provide a new and improved pipe-bending machine which is simple and durable in construction and very effective in operation.
The invention consists in the `construction and arrangement of various parts and details, and combinations of the saine, as will be fully described hereinafter, and then pointed out in the claims.
Reference is to be had to the accompanying drawings, forming a part of this specication, in which similar letters ot' reference indicate corresponding parts in both the iigures.
Figure l is a side elevation of my improvement with parts broken out, and Figi 2 is a x x of Fig. l.
A suitable frame, A, supports the bed-plate B, on which is secured, in the middle, the frame C, in the top-plate of which screws the screw D.
The bed-plate B supports the bottom plate, E, having a longitudinal dovetailed groove, in which are adapted to slide the heads F, on the upper end of each of which is pivoted the supi'or the reception of the pipe to be bent. The sliding heads F are held in place by pins H, inserted in apertures formed in the bottom plate, E.
The frame O is provided on one side with a pivoted dropplate, C, held in place by a pin, C2, which, when removed, permits of opening the side drop-plate, O', for the insertion of very crooked pipes.
The semicircular bending-block I is straight on its top, and is provided with a semicircular groove in its rim.
The operation is as follows: The plpe J to be bent is placed on the supporting-blocks G, which are placed at such a distance as to correspond tothe bend to be given to the pipe. The bending-block I is then placed on top of the pipe J, with its groove fitting into the Serial No. 225,794. (No model.)
pipe, the center of its straight top being directly under the end of the screw D. The latter is then moved downward by hand, hydraulic power, steam-power, or other suitable 5 5 means. The pressure exerted by the screw D against the block I causes the bending of the pipe, and tlleblocks G, turning on the pivots, follow the bent pipe. The semicirular shape of the block I permits of bending the pipe J 6o into a U shape, if desired.
Having thus fully described my invention,
. I claim as new and desire to secure by Letters Patent- A l. In a bending-machine, the combination, with a semicircularly-grooved block receiving a downward motion, of two grooved supporting-blocks placed one at each side of the said semicircular block, and adjustable heads on which the said supporting-blocks are piv- 7o oted, substantially as shown and described.
2. In a bending-machine, the combination, with a semicircularly grooved block and means, as described, for moving the said block downward, of grooved supporting blocks 7 5 placedVA at -the sides of the said semicircular block, and longitudinally-adjustable heads on which the said supporting-blocks are pivoted, substantially as shown and described.
3. In a bending-machine, the combination, 8o with a sernicircularly grooved block and means, as described, for moving the said blockv downward, of grooved supporting blocks, dovetailed heads on which the said supportingblocks are pivoted, and a dovetailed bed-plate in which the heads are held and can slide, substantially as shown and described.
4. In a bending-machine, the combination, with a semicircularly grooved block and means, as described, for moving the said block 9o downward,ofgroovedsupporting-blocks,dovetailed heads on which the supporting-blocks are pivoted, a dovetailed bed-plate having apertures in which the said heads can slide, and pins fitting into the said apertures for holding Vthe said heads in place, substantially as shown and described.
GEORGE B. BROVNSON.
