for example, four or iive holes open between each clamp for the insertion of rivets. The clamps should be suiciently closely spaced, however, to prevent the plates and angles from separating inasmuch as it is very important that these members be maintained in a mutually tight pressed relation for the riveting operation.

If the holes in the angle are punched close enough to the flange I2 thereof, the end of the oiset portion 22 of the bolt 3l) will engage the same to prevent rotation of the bolt when the Wing nut 23 is being rotated into engagement with the outer plate. I

It may thus be seen that the clamps may be applied from a position exteriorly of the structure, and that but one man can easily and expeditiously perform this operation. After rivets have been inserted in the open holes of the structure, the clamps are removed and rivets may then be inserted in the holes thus provided to complete the operation of riveting the plates to the angle framework.

It is to be understood that the form oi our invention, herewith shown and described, is to be taken as a preferred example of the same, and that various changes in the size, shape and arrangement of parts, may be resorted to without departing from the spirit of our invention, or scope of the appended claims.

Having thus described our invention, we claim:

1. A riveting clamp comprising abutment means adaptable to be inserted through an opening, a threaded portion above said abutment portion, a manually operable nut engaging said threaded portion, and a finger piece above and offset from said threaded portion.

2. A riveting clamp comprising a threaded portion, abutment means adaptable to be inserted through an opening, said abutment being an oblique extension of said threaded portion, a manually operable nut engaging said threaded portion, and a iinger piece above and offset from said threaded portion.

3. A riveting clamp comprising abutment means adaptable to be inserted through an opening, a threaded portion above said abutment portion, a manually operable nut engaging said Cil threaded portion, said nut being a wing nut, and a nger piece above and offset from said threaded portion. i

4. A riveting clamp comprising a threaded portion, abutment means adaptable to be inserted through an opening, said abutment being an oblique extension of said threaded portion, a manually operable nut engaging said threaded portion, said nut being a wing nut, and a finger piece above and oiset from said threaded portion.

5. A riveting clamp comprising abutment means adaptable to be inserted through an opening, a threaded portion above said abutment portion, a manually operable nut engaging said threaded portion, and a finger piece above and offset from said threaded portion, said finger piece being an angularly projecting upper extension of said threaded portion.

6. A riveting clamp comprising a threaded portion, abutment means adaptable to be inserted through an opening, said abutment being an oblique extension of said threaded portion, a manually operable nut engaging said threaded portion, and a finger piece above and oiset from said threaded portion, said nger piece being an angularly projecting upper extension of said threaded portion.

7. A riveting clamp comprising abutment means adaptable to be inserted through an opening, a threaded portion above said abutment portion, a manually operable nut engaging said threaded portion, said nut being a wing nut, and a finger piece above and oiset from said thread- Ved portion, said iinger piece being an angularly projecting upper extension of said threaded portion.

8. A riveting clamp Comprising a threaded por tion, abutment means adaptable to be inserted through an opening, said abutment being an oblique extension of said threaded portion, a manually operable nut engaging said threaded portion, said nut being a Wing nut, and a nger piece above and oifset from said threaded portion, said linger piece being an angularly projecting upper extension of said threaded portion.
