RIVETING- MACHINE.

Application filed April 3,

T 0 all whom it may concern:

Be it lmown that I, CHRISTIAN J. JOHN- SON, a citizen of the United States, residing v at Colfax, in the county of Dunn, State of Wisconsin, have invented certain new and useful Improvements in Riveting Machines; and I do hereby declare the following to be a 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.

This invention relates to new and useful improvements in riveting machines.

One object of the invention is to provide a novel and improved means for adjusting the height of the anvil of the riveting machine to conform to the length of the rivet, and the thickness of the work.

Another object is to provide a device of this character which can be readily applied to riveting machines, and which is adjustable to raise or lower the anvil.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is a side elevation of a riveting machine showing the adjusting attachment thereon, and partly in section to show the lower end of the anvil in one of the depressions.

Figure 2 is a top plan view of the disc.

Referring particularly to the accompanying drawing, 10 represents the frame of the riveting machine, which is U-shaped in outline, and having the lever actuated hammer or depressing member 11 mounted in its upper arm, and the anvil member 12, with its spring supported rivet embracing sleeve 12, disposed in the lower arm. Rotatably mounted in the base 13, of the frame of the machine, beneath the lower end of the lower arm of the frame, is a horizontal disk 14 having a circular series of depressions 15 in its upper face, said depressions being of different depths, and each being arranged to receive the lower end of the anvil, when said disk is properly rotated on its central pivot 16. The peripheral edge of the disk 14 projects forwardly beyond the outer end of the lower arm of the frame 10, to permit same being grasped when. it i e r d t ro a e the d sk to dis- 1923. Serial No. 629,640.

pose the proper depression directly beneath the lower end of the anvil 12.

When a shorter rivet is being used, the disk is rotated to dispose one of the shallower depressions beneath the anvil, while when a longer rivet is used a deeper depression is presented beneath the anvil, upon rotation of the disk to the proper de ree.

Xtending between each pair of depressions 15 is a groove or channel 17, for guiding the lower end of the anvil member 12 from one depression to the next.

lVhat is claimed is:

1. A riveting machine including an anvil supporting frame, the anvil projecting be low the lower side of the frame, and a rotatable disk mounted beneath the lower end of the anvil and having a circular series of depressions of different depths for successively receiving the lower end of the anvil to raise and lower the anvil.

2. The combination with the frame of a riveting machine having an anvil supported therein, with its lower end projecting below the frame, of a horizontal disk rotatably supported beneath the frame and anvil and having a circular series of depressions of graduated depths adapted to be brought successively beneath the anvil for receiving the lower end of the anvil.

3. The combination with the frame and anvil of a riveting machine, the anvil having its lower end projecting below the frame, of a disk rotatably supported in a horizontal position beneath the frame and having depressions for successive reception of the lower end of the anvil for holding the anvil at different elevations in accordance with the size of rivet used.

4. The combination with the frame of a riveting machine and its anvil projecting below the frame, of means movably supported beneath the frame and anvil and arranged to be moved transversely of and in contacting relation to said anvil for elevating and lowering the anvil to different degrees. V

In testimony whereof, I afiix my signature, in the presence of two witnesses.
