JULIUS KELLNER, OF CALUMET, PENNSYLVANIA.
BENDING-MACHINE.
T all whom 'it may concern:
Be it known that T, Jones KELLNER, a resident of Calumet, in the county of VVestmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Bending-Machines, of which the following is a specification.
My invention relates to bending machines and more particularly to a new and improved metal bending machine designed for bending metal sheet material as well as bars of metal.
An objectof the present invention is to provide a new and improved bending machine of the class mentioned capable of forming a variety of bends in a metallic sheet or bar or other materials as required.
In the accompanying drawings, which illustrate an application of my invention, Figure l is a plan of a bending machine embodying my invention; Fig. 2, a side elevational view; Fig. 3, a vertical sectional view taken on line ITIIII of Fig. 1; Fig. 4, a part elevational and a part sectional view being taken on line IVIV of Fig. 5; Fig. 5 a front view; and Fig. 6, a sectional view taken on line VI VI of Fig. 1.
Referring to the drawings, 2 designates a bed-plate, which in the use of my invention is mounted on a support, not shown, at a convenient distance from the fioor level. Plate 2 preferably comprises a metallic casting formed with housings 3, and a hollow center as shown at 4, and an upwardly projecting wall or member 5. Partially covering the central opening I provide a work supporting plate 6. and secured thereto or cast integral therewith are two supporting-members 7. As illustrated said members are secured to the bed-plate by means of bolts 8 and each comprises two inclined members 9 and 10, front and rear upright members 11 and 12, and a horizontal member 13. The inclined members 9 are each formed with an opening 14 having an enlarged portion 14, while the inclined members are formed with an internally threaded opening 15 through each of which is passed threaded member 16 of a crank arm 11.
Mounted on each of the supporting mem bers and adaptable for movement thereupon is a carrier block 18. Each of the carriers 18 is provided with an inwardly projecting part or member 19 designed to extend through the opening or slot 14 0f the re- Specification of Letters Patent.
Application filed July 2, 1910.
Mounted on said plate Patented Dec. 27, 1910.
Serial No. 570,185.
spective supporting members and to be attached to a reduced end 20 of member 16 by means of a cotter 21. The inclination of members 9 is preferably forty-five degrees and the threaded members 16 are each disposed parallel with the respective members 9. The respective crank-arms are connected by an operating bar 22 as particularly shown by Fig. 1, and both of said carriers 18 are simultaneously moved by a movement imparted to bar 22. From the construction described it will be noted that the carriers have a combined vertical and lateral movement with respect to the bed-plate.
Located on the front flat faces 23 of the carriers and extending across the machine from one carrier to the other, I provide a detachable movable work clamping-member 24. As particularly shown by Fig. 5, the detachable clamping-member 24 is formed with slots 25 and 26 thereby enabling said member to be attached to and detached from pins 27 projecting from the respective faces 23 of the carriers. The detachability of clamping-member 24 is important in that it permits some shapes to be placed in position to be bent that could not otherwise be placed in the desired position.
Located under the movable clampingmember 24 and secured to the front upright members 11 of the supports by means of countersunk bolts 28, I provide a fixed clamping member 29. The front face of member 29, when the movable clampingmember 24 is in its lowermost position as shown by .Fig. 3, is in alinement with the front face of member 24.
Mounted in the housings 3 and secured therein by caps 30 are the journal ends 31 of a partially rotatable bending-member 32. As illustrated, the bending-member proper is of rectangular form and provided with a fiat work engaging face 33, while its journals 31 are cylindrical and offset with respect to the center line of the angular portion, that is to say, the center of the respective cylindrical journals is in line with the face 33, as well as in line with the front face of the fixed clamping-member and in line with the front face of the movable clamping-member when the latter is in the position shown by Fig. 3.
The bending-member is, as shown, actuated by means of levers or arms 35 mounted on the squared ends 36.
Fig. 4, illustrates a piece of work or material 37 to be bent and the manner ofbending the material. Referring to said view it will be noted that the material is tightly clamped between the movable and fixed clamping-members with an end, shown by dotted lines, projecting beyond and over the bendingmember, shown in dotted lines in its lowered position. The material is bent to any desired angle over an edge of the movable clamping-member by moving the bending-member from the position shown by dotted lines to the position shown in full lines or any intermediate position.
WVhat I claim is 1. In a bending machine, a fixed clamping-member, a movable detachable clamping-member cooperating with the fixed clamping-member for holding the material to be bent, positively operated means for moving the movable clamping-member vertically and laterally with respect to the fixed clamping-member, and a member for bending the material over an edge of the movable clamping-member.
2. In a bending machine, a fixed clamping-member, a movable clamping-member, means for moving the movable clampingmember vertically and laterally with respect to the fixed clamping-member, comprising an inclined slotted support, a carrier provided with a member extending into the opening of the support and a threaded member connected to the carrier, and a bending-member for bending the material over an edge of the movable clamping-member.
3. In a bending machine, a fixed clamping-member, a movable clamping-member, means for moving the movable clampingmember vertically and laterally with respect to the fixed clamping-member comprising a carrier, an inclined support, and means im parting a positive motion to the carrier, and a bending-member for bending the material over an edge of the movable clampingmember.
4. In a bending machine, a fixed clamping-member, a movable clamping-member, means for moving the movable clampingmember vertically and laterally with respect to the fixed clamping-member comprising inclined supporting-members, carriers mounted on the inclined-members and means for moving the carriers on the supports, and a bending-member for bending the material over an edge 01"? the movable clampingmember.
