and inserting and upsetting the rivets, and
requires a great deal of time. Frequently the riveting operation has to be performed in a position where it is inconvenient and sometimes almost impossible to handle the rivets and the riveting tools.
The primary object, therefore, of my present invention is to provide a tool by means of which the lapping edges of sheets of metal can be easily and quickly interlocked or secured together in such a way that their premature or accidental separation will be impossible.
A further object is to provide a tool of simple, rigid and strong construction, and one which will :be comparatively cheap and economical to the purchaser and comparatively inexpensive to manufacture, and which will greatly cheapen the cost of binding or securing seams in the work above described.
In the accompanying drawings forming part of this specification,
Figure 1 is a side view of a metal pressing tool embodying my invention,
Figure'2 is a detail view, partially in section, of the head of the tool, showing the operating jaws mounted thereon,
Figure 3 is a detail view, also in section, showing the jaws in the act of pressing the boss or button into the metal to hold the edges together,
Figure 4 is a detail view, also in section, showing another form of a pressing tool, for
use in close or confined work where it isnot possible to reach with the flat jaws,
Figure 5 is a detail sectional view of the device holding the levers of the-tool in their closed position,
Figure 6 is an edge view of one of the --jaws, showing a straight clamping end therefor.
In the drawing, 2 represents a plate havmg holes therein to receive bolts 3 and 4, arranged in pairs at opposite ends of the plate and passing through said holes and screwed into similar holes provided in a corresponding plate on the opposite'side of the tool. Jaws 5 and 6 are pivoted on the bolts and p'roljaect outwardly beyond the plates 2 and'haveopposing :taces7, the jaw 5 being provided with a socket 8 having two diameters into'which a pin 9,015 the larger diameter, having a rounded outer end 10, is inserted. The jaw 6 has a recess 11 therein opposing the rounded end of the pin 9, and
said jaws, as indicated in Figure, 4, are
turned laterally with respect to the plane .of the tool for the convenience of the operator, the jaws being'at an angletoithe work,
while the tool itself may be inclined eitherabove or below the hands of the operator. This arrangement of the aws I have found to be ofparticular advantage in a tool of this kind, as it allows the workman to press the bosses in the lapping edges of the metal above his head or at a point below the normalwor'king position of the hands, the offset allowing the workman :to stand in the most convenient position.
Each of the jaws 5 and 6 is provided with an arm :12 which extends backward'ly be tween the plates 2 ':to a point adjacent to the bolts 3. Levers 13 have flattened end portions 14 which are pivoted on .the bolts 3 and are provided with recesses 15 to receive heads 16 on therends' of the arms 12. The opposing curved faces ofthese ends 14: are provided -with :teeth 17 meshing with each other to insure simultaneous and uniform movement of the :levers. Evidently, when the levers are swung toward each other, the'arms 12 will be separated and the jaws brought together to clamp'the material between them:
Set-screws 1:8 are preferably mounted in the levers 13 in position to contact with each other and regulate the travel of the levers and jaws by which means proper adjustment can be obtained to suit different thicknesses orgauges of metal. At the outer ends, ofth-e levers holes 19 are provided. A
bar 20'has pins 21 and=22 mounted therein i said bar 20 is preferably provided with a loop 23 by means of which the bar may be conveniently raised for locking and unlocking, or hung on a support, or may be lifted with the work clamped between the jaws.
When the tool is used on sections of a ventilator, cornice, skylight work or straight sheets, or parts of same, it will be found convenient to raise the section by means of the tool itself, the jaws being closed, clamping the lapping edges and heldhin their closed position by the bar 20. The levers 13 may be of any suitable length and the jaws may be varied in size, as desired.
In Figure on an overhead seam. A sheet metal wall 24: has a flange 25 around which aflange 26 of the wall 27 is looped by any suitable means used in the forming or folding of sheet 7 metal. The workman then takes'the pressing tool and positions the jaws to grip the folded and lapping edges of the metal between them, and upon closing the jaws the pin 9 will force the metal of the lapping edges into the recess in the opposite jaw and form a boss or raised portion 28 on one side and a corresponding depression on the opposite side. The jaws are then released and moved along the fold and the operation re peated. v
The bosses may, of course, be as close to gether as the operator desires and according to the character of the work and strain to 1' which the fold will be subjected, and when completed, the folded edges will be firmly secured together and the use of punching tools and riveting devices entirely eliminated for this class of work.
In Figure 6 I have shown a jaw 5 with a straight clamping face instead of one that is offset or curved, as indicated in the other figures. These jaws are mounted in the platesin substantially the same way and are operated through the movement of the lever handles 13.
In various ways the details of construction herein shown and described may be modified and still be within the scope of my invention.
I claim as my invention: v 1. A tool of the class described comprising a head composed of plates and bolts passing therethrough for holding said plates in parallel relation, spaced from each other, a pair of levers mounted on a corresponding number of said bolts at the outer ends of said plates, the outer ends of said levers projecting beyondthe corresponding ends of said plates and laterally turned with respect thereto, one of said projecting ends having a socket therein and a male die fitting within said socket and provided with a rounded outer end, the projecting end of the other lever having a concavedepressiou 3 I have shown the tool at work therein to register with the rounded end of said male die and form a female die therefor, said projecting ends being adapted to clamp the interlocking edges of sheet metal together and form a boss on one side thereof and a corresponding depression on the other side for securing said edges together,
a pair of levers mounted on a corresponding number of said bolts at the outer ends of said plates, the outer ends of said levers projecting beyond the corresponding ends of said plates, one of said projecting ends having a socket therein and a male die fitting within said. socket and provided with a rounded outer end, the projecting end of the other lever having a concave depression therein to register with the rounded end of said 'male die and form a female die therefor, said projecting ends being adapted to clamp the interlocking edges of the sheet metal together and forma boss on one side thereof and a corresponding depression on the other side for securing said edges together, and operating levers having hand grips mounted on boltsyat the other end of said plates for simultaneous movement and having means for engaging and actuating said first named levers. V
3. A tool of the class described comprising a head composed of plates and two projecting beyond said face and the other face with an opening registering with said pin, and operating levers having hand grips pivoted on bolts at the other end of said plates and means between the levers for causing simultaneous movement thereof and having means for engaging and actuating said first named levers.
In witness whereof, I have hereunto set my hand this 17th day of March, 1916.
JOHN HELWIG.
