EDGlNG-MACHINE FOR SHEET METAL.
SPECIFICATION forming part of Letters Patent N 0. 670,504, dated March 26, 1901.
Application filed January 23, 1901. Serial No. 44,421. (No model-J M To aZZ whom it mung concern:
Be it known that I, ALBERT DANZER, a citiing forth myimprovements.
town, in the county of Washington and State of Maryland, have invented a new and useful Improvement in Edging-Machines for Sheet Metal, which improvement is fully set forth in the following specification and drawings.
. My invention relates to improvements in edging-machines embodying means for bending the edges of sheet metal preparatory to joining same by a roll-seam; and my object is to provide an edger of this character which will embody the elements of simplicity, economy, rapidity, and eifectiveness, which object is attained in the device illustrated in the accompanying drawings, in which- Figure 1 is a plan View of the machine, set- Fig. 2 is'a crosssectional view of same on line 2 2 of Fig. 1. Fig. 3 is a detail View in perspective of a portion of the guide-plate and lever. Fig. 3 is a similar view of the stationary folding-blade. Fig. 4'is an end elevation showing more clearly the operating-lever, auxiliary pawl, &c. Fig. 5 is an elevation of the opposite end with a portion broken away to show more clearly the manner of adjusting the journal-boxes. Fig.
' 6 is a side view of a piece of sheet metal having its edge bent up at a right angle. Fig. 7 is a similar View showing the edge bent entirely back for roll-seaming, and Fig. 8 shows two sheets of metal in position to form a rollseam union.
Similar characters of reference indicate similar parts throughout the several views.
The machine consists of a base 1, having vertically-extending end walls 2 2-, said end walls being provided with projections or lugs 3, which are cast integrally therewith.
4 representsjournal-boxes provided with offstanding lugs 5, which rest on the end walls 2 2. These lugs have slotted'openings to receive the threaded bolts 7, which secure the boxes to said end walls. Threaded into the lugs 3 are set-screws 6, by means of which the journal-boxes may be properly adjusted to bring the folding-blades in proper alinement.
The base 1 is provided longitudinally with an angular recess, in which is secured the stationary-folding-blade 8 by means of suitable bolts 9, said folding-blade having a series of slots 8, into which the ejectorsmay pass as the machine is operated.
In the journal-boxes4 is mounted a rock shaft or member 11, carrying a folding-blade l0,secu red thereto by means of screws or bolts, and this folding-blade 10 has an extension 10, which projects downward and is so shaped as to pass under the projecting edge of blade 8 when the lever 19 is thrown forward, as will presently be described.
Seated in a groove in the base 1 is a rod 13, to which is rigidly secured a guide plate 'or leaf 12, over which the sheets of metal pass When being fed into the machine, and this rod 13 has hearings in the end Walls 2 and is provided at one end With an upwardly-extending portion 13', to which is attached one end of a tension-spring 14. The opposite end of said spring being secured to the eye 14' serves to hold the guide plate or leaf 12 in a position above the edge of the stationary folding-blade 8, the pin 14 forming a stop for the forward, as at 16, to pass through the slots 8 and to project under a portion of blade 8, said ejectors being held in place by set-screws 17, all as clearly shown in Fig. 2.
18 represents a gage-plate adjustably secured to the base 1 by set-screws 18, which pass through elongated openings, and the plate is further provided with slots, through which the ejectors may operate, and by setting said plate 18 forward or back the Width of the seam in the sheet metal can be regulated. Y
The rock-shaft 11 is operated by a handlever 19, which is secured tosaid rock-shaft by a key or pin 20, this lever being provided with a projection 2l,which coming in contact with the stop 22 on the end wall governs its backward movement.
In preparing tin or other sheet metal for roll-roofing it is necessary to unite the an "interlockin g roll-seam that mydevice is the front end of the gage-plate 18. The lever 19 is then thrown forward, which causes the extension of the folding-blade 10 to impinge against the said sheet of metal, forcing it down and under the stationary blade 8, thereby forming a hook, as shown at b, Fig. 7. Then as the lever is thrown back the folding-blade 10 is withdrawn, and the extensions 16 of the ejectors, passing through the openings 8' and under the blade 8, force the sheet of metal out from under said blade, when it may be turned around to have the operation repeated on its opposite edge. When the edges of two sheets have thus been operated upon, they are placed together, as shown at b b, Fig. 8, to be pressed together and soldered. When it is desired to bend the edge of the metal at a right angle, as shown at a, Fig. 6, for flat-roofing, the lever 19 and its cooperating parts must not be thrust forward all the way, and to govern the stroke for this form of bending I provide a pawl 23, which is secured on a stub-shaft 24, and this pawl normally rests out of position, as indicated by dotted lines in Fig. 4, but when thrown forward it interrupts the stroke at the desired point.
Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-
1. In an edging-machine for sheet metal, the base, and end walls, supporting adjustable journal-boxes, the stationary fo1dingblade secured to said base, and a guide plate or leaf, in combination with a rock-shaft, having a folding-blade, and provided with a plurality of ejectors; all for the purposes and substantially as set forth and described.
2. In a machine for edging sheet metal, the base, and end walls, supporting adjustable journal-boxes; a rock-shaft having a foldingblade, and a plurality of ejectors, in combination with a stationary folding-blade, with openings in said blade for the ejectors, and a guide plate or leaf secured to a rod, substantially as specified.
3. In a machine for edging sheet metal, the rock-shaft operated by a lever, the pawl for interrupting the stroke of said lever; a folding-blade carried by the rock-shaft, a stationary blade secured to the base, and an adjustable gage-plate, substantially as and for the purposes specified.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
ALBERT DANZER.
