WILLIAM KENT, OF JERSEY CITY, NEW JERSEY.
iVlAQHlNE FOR BENDING AND FLANGING METAL PLATES.
SPECIFICATION forming part of Letters Patent No. 357,716, dated February 15, 1887.
Application filed October 25, 1886. Serial No. 217,108. (No model.)
To all? whom it may concern.-
Be it known that 1, WILLIAM KENT, a citizen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Machines for Bending and Flanging Metal Plates; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to certain novel and useful improvements in machines for bending and flanging metal, and has for its object to.
produce a machine which shall be capable of performing these functions with accuracy and speed; and with these ends in View my invention consists in certain details of construction and combination of elements hereinafter fully set forth, and then specifically designated by the claims.
In order that those skilled in the art to which my invention appertains may more fully understand the same, I will proceed to describe its construction and operation, referring by letter to the accompanying drawings, formingapart of this specification, in which Figure l is a perspective of my improved machine, the bending and flanging machinery being shown in normal position; Fig. 2, a similar view showing the blank bent up preparatory to flanging or lapping the edges thereof inward; Fig. 3, a similar view, but with the several parts in their proper relative position after the edges of the blank have been flanged inward; Fig. 4, a front elevation of the machine as shown at Fig. 2; Fig. 5, a plan view of the machine as shown at Fig. 2; Fig. 6, a central vertical cross-section of the machine with the blank and anvil in their proper relative position preparatory to bending; Fig. 7, a central vertical cross-section of the machine as shown at Fig. 2, and Fig. 8 a similar view of the machine as shown at Fig. 3.
Similar letters denote like parts in the several figures.
In order to clearly illustrate this improvement, I have thought best to exemplify the manufacture of some well-known and serviceable product, and I have therefore selected a header, such as is especially adapted for water-tube boilers. I do not, however, wish to be understood as identifying my present invention with any particular article of manufacture, as my improvement is serviceable in a great variety of instances where the bending or Hanging of sheet metal is to be accomplished. A is the frame of the machine. B O are shafts, having mounted thereon,outside the frame, gear-wheels D, adapted to mesh with each other.
E is a ledge cast with or rigidly secured to the frame, and F are leaves pivoted between the sides of the frame by means of pins a, which extend within the lugs 1), formed integral with said leaves, so as to be capable of a swinging movement, while at the same time, when in their normal position, they are in the same horizontal plane with the ledge E, thus forming a platform upon which the blank may be placed. To the under side of each leaf are secured segment-gears G, with which mesh the cogs H on the shafts B C.
Q are extension-leaves, which are attached to the leaves F, preferably by dowel-and-socket connection, as shown at It, Fig. 1.
S are flangingbars pivoted to the leaves Q, between ears T, which ears are formed integral with said leaves, at the extremities thereof.
U are segmentgears secured to the under side of said bars.
V is the blank, and W the anvil, the relative position of these parts being as shown at Fig. 6.
X are shafts journaledin bearings at the upper part of the frame, and Y are cog-wheels at the extremities thereof, adapted to mesh with each other.
Z are cogs (four in number) secured in pairs on the shaft-s X, each pair being adapted to mesh with the segment-gears U when the latter are in the position shown in Fig. 2.
By turning the wheels D in the direction indicated by the arrows thereon (see Figs. 4: and 5) the cogs H will operate in conjunction with the segment-gears G to fold the leaves F upward. This operation is continued until the folding of the leaves has caused the blank to be bent at the desired angle, (in this instance a right angle,) when the blank is ready for the operation of the flanging mechanism, as seen at Fig. 2. The wheel A is now turned in the direction indicated by the arrow, (see Figs. 4 and 5,) which will cause the cogs Z to mesh with the segment-gears U and fold the flangers S inward, thereby bending the edges of the blank down upon the anvil. The flangers are so pivoted within the leaves Q that when they are in the position shown in Figs. 2 and. 7 they are in different horizontal planes, so that it will be readily understood that said flangers will, by their operation, cause the edges of the blank to be overlapped, as shown in Figs. 3 and 8.
It is obvious that said edges may be bent so as to meet and not overlap by simply placing the anvil central of the blank and operating the flangers in the same horizontal plane.
Any well-known method of applying power to the machine may be employed.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In a machine for bending and fianging metal plates, a stationary ledge adapted to support the blank and anvil, leaves pivoted laterally to the frame, flangingbars pivoted within said leaves,and gearing for folding said leaves and bars, substantially as set forth.
2. The combination, with the leaves F, pivoted laterally to the frame of the machine and having segment-gears G secured to the under side thereof, of the extension-leaves Q,secured to the leaves F, flanging-bars S, pivoted laterally to said extension-leaves, segment-gears U, secured to the under side of said bars, cogs H on shafts B O meshing with gears G, means for revolving said shafts, cogs Z, secured on shafts X and adapted to operate the segments U, and means for revolving said shafts, substantially as and for the purposes set forth.
In testimony whereof I affix my signature in presence of two witnesses.
WILLIAM KENT.
