`Letters Patent No. 97,762
, dated December 14, 1869. I
Mov- IMPRQZEMENT IN` MACHINES FOR 4B ElllDIlilG- .AND FOLDING SHEET-:METAL Schedule referred to :ln these Letters Ivaterit and making part of the same.
To all 'whom it may concern:
Be it known that we, JAMES B. CLARK and LUCAS C. CLARK, of Plantsville, in` the county of' Hartford, and State of Connecticut, have` invented new and -usen ful Improvements in Machine for Bending oI- Folding' Sheet-Metal; and wedo herebydeclare thatthe following is a full, clear,.and exact description thereof,
reference being had to the accompanying drawings, making part of this specicatiomin which- Figure 1 is a front elevation of our invention.
Figure 2 is a sideelevation of the same.
Figure 3 is a close sheet-metallock.
Figure 4 is au open sheet-mtal lock.
Similar `letters of reference indicate like parts. l Our invention consists in the use or employment of two swinging brakes, in combination with a foldingplate, and also in the arrangement of'a part of the upper brake, so that it' receivesa circular andvertical motion in turning an open lock. C
A designates th'e bed or frame of the machine, to which is rml'y secured afoldingLplate, B.
Underneath the folding-plateV B is a swinging brake, C, .which is fitted to swing in bearings, the' position of which bearings is indicated by the broken circle in lig. 2.
Immediately back'of the brake C is a brake, D,
t which is pivoted to swing in bearings, E.
The upper end of the 'brake D is pivotedat each end to a cam, F, which earns are. connected to each other by a bar, G, to which is'attached the lever H.
The bedA is provided with an arm, I, on theend of which is a roller, a, whielrts into a corresponding i depression in the cams F.:
- 0n the front side of the'brakeD is a sliding plate, J, which lis secured to the same by screws c c, running through the slots d d.v l
When desired to turna close lock, the plate J is brought down and secured rigidly in place by the pin t'.
The metal plate K is inselted with one edge against the shoulder m, on the brake C, as shown in tig. 2.
- the form shown in g. 3.
' To turn an open lock, fig. 4, the pin i is removed,
' which allows the springs, back side ofy the brake D,
indicated by broken lines n, to raise the plate J until the screws c c -:strike the upper ends of the slots dd. A s the brakes D andC are brought forward, the plate J strikes the metal K above thefolding-plate B so far as to allow the metal to assume a rounding form, and when the brakes are nearly as far forward as the cams F will throw them, a portion of the cams F strike the projections 'o,on" each end of plate J, and throw it downward toward the folding-plate B, until the lock '.is vformed as closeas may be desired.
When the plate J is raised for the purpose of turning open locks, it cannot be made to move forward far Yenough to form the metal as close to the folding-plate B as is desired, without the vertical movement of the same, substantially as described.
n What we claim as new, and desire to secure by Letters Patent, is i 1. The combination of the swinging brakes C and D, and the folding-plate B, substantially 'as and for the purpose described.
2. The combination of the swinging brakes C and D, folding-plate B, brake-plate J, and cams F F, all constructed and operated substantially as set forth. JAMES B.. CLARK. LUCAS C. CLARK. Witnesses: Y
