IMPROVEMENT IN SEAMING-v-MACHINE.
The Schedule referred to in these Letters Patent and making part of the same.
To `dll whom fit may concern:
Be itknownthat I,.OHARLES E. BANCROFT, of
Montpelier, in the county of Washington, and Sta-te of Vermont, have invented a new and valuable Improvement iu Seaming-Machines; and l do hereby declare that lthe following is a full, clear, and Aexact description ot' the construction and Voperation of the sume, reference being had tothe annexed drawings,
,V-'niaking a part of this specification, and to the letters and iigures of reference marked thereon.
n Figure ],of the drawings, is a representation of a central vertical section Aof my invention, taken longi- Vtn dinally.
' A Figure 2 is a top view of the saine.
Figure 3 is a front view of the s'ame.
My invention relates to double-scathing machines for tin-work, and consists, mainly, in the construction and novel arrangement of. devices, whereby the required pressure on the work', between the formingdisks, is accomplished automatically.
The letter A, of the drawings, designates the bedpieee of my machine, having the anches ce a on each side, upon thelower edges ot' which it'rests.
rlhe longitudinal slot z is formed in the central portion ot' the bed-piece.
B designates a metal frame or support, whose footpiate b is secured to the bed-piece by screws.
- The upright b and*strengthening-rib y support thel ledge c, turned upward at the ends to form bearings for the shaft c of the vertical forming-disk G.
These bearings are rendered rm by the brace t.
D represents a metal flame or support, whose footplate, d, slides between the ilanches a a on the upper surface of the bed-piece A, being secured firmly to the same, when in proper position, by the bolt andA nut s, operating through the slot z. The upper part of the support D is turnedtbrward, to form the upper bearing, Z, of the vertical shaft e, whose lower end revolves in a cup or bearing formed in the head of the elevating-screw P.
Above the upper bearing-plate l, the vertical shaft e forms an elbow, and again turns upward, its upper end constituting the pi'ntle, about which the horizontal forming-disk E revolves.
The horizontal disk E can be removed, and one of different size employed in its place, when it is so de# sire-d.
A guard or stop, Tais-fastened@ the vertical shaft e, below thelplate l, to prevent the horizontal disk E from swinging beyond a cert-ain point.
This is accomplished by the striking of the projecting arm or stop 7g' against the edge of the support D.
Under the ledge o, near its forward end, is pivotedthe horizontal clamp-wheel F, forming a counter-support to the outer portion of the vertical disk C, when in operation, and preventing any springing or friction of the same.
In the head'of the elevating-screw P are the holes n n, for the reception` of the end of a small lever, whereby it is turned.
K designates the haud-crank, by means of which the machine is operated.
The horizontal disk E is adjusted, vertically, by
turning the elevating-screw P, and, horizontally, by
sliding the frame D, the bolts having been previously loosened.
The work having been entered, in position, between the disks, the hand-crank K is turned in the direction indicated by the arrow, when the horizontal disk E is immediately drawn against the vertical disk C, and the work of searuing or bending the metal plate between them easily and readily performed.
When it is desired to remove the work from between the forming-disks, a reverse movement of the crank K will throw the horizontal disk off, or cause it to turn away, 0n its eccentric shaft e, loosening the pressure on the work at once.
The centre of the bearing of the vertical shaft e, in the plate Z, is usually taken to the left of the perpendicular, erected on the central point of the lower bearing in the head of the screw I. Thus, a slant is obtained in the vertical shaft e, which is advantageous in tightening on the work, and in loosening it from between the horizontal shoulder of the disk C and the horizontal surface of the disk E.
The machine will work excellently' well, however, with a perpendicular shaft.
Sometimes, instead of the single eccentric vertical shaft e, I employ two shafts, one, upon the top of which the horizontal disk revolves, having its bearings in arms extending out from the other, which has its bearings in the. plate Zand elevating-screw P.
iVhat I claim as my invention,and desire to secure by Letters Patent, is-
1. The upright shaft e, arranged with a cam or bend in its upper part, and supporting the horizontal disk of a double-scanning machine', as described.
2. In combination with the horizontal disk of a,
double-seamiug machine, the automatic cam-shaft e, having elevating-screw P'and stop h, as shown and described.
