3 Claims.

The present invention relates to new and useful improvements in riveting tools and comprises an anvil adapted to be gripped by the hand of a workman for holding the anvil against the tail of the rivet while the riveting hammer is being used on the head of the rivet.

An important object of the present invention is to provide a riveting tool of this character adapted to absorb the shock and vibration subjected thereto by the hammer before the same reaches the hands and body of the workman.

A further object is to provide a tool of this character of simple and practical construction, which is strong and durable, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the de tails of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which Figure 1 is a side elevational View,

Figure 2 is a longitudinal sectional view taken substantially on a line 22 of Figure 1,

Figures 3 and 4 are transverse sectional views taken respectively on the line 3-3 and A54 of Figure 2,

Figure 5 is a side elevational View of the inner anvil,

Figure 6 is a similar View of the outer anvil, and

Figure 7 is an end elevational view of the outer anvil.

Referring now to the drawings in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral 5 designates a cylindrical barrel or casing for the anvil having the outer anvil 6 slidably mounted in one end of the barrel and the inner anvil 1 slidably mounted in the barrel inwardly of the outer anvil. The barrel is formed at di ametrically opposite sides with longitudinally extending slots 8 for receiving the outer ends of the screws 9 which are threaded into the outer anvil to limit the reciprocating movement therethe barrel and slidably mounted in a threaded plug I4 which is threaded in the adjacent end of the barrel. The guide I3 is likewise adapted to contain a quantity of babbitt metal [5 to add weight thereto and the rear end of the guide is closed by means of a threaded plug IE.

A coil spring I! is positioned on the guide with one end abutting the plug l2 and the other end abutting the plug [4 whereby to yieldably project the anvils 6 and l forwardly.

When the anvils are projected in their forwardinost position, the screws 9 engage the front ends of the slots 8 and the front end of the anvil 5 is then flush with the front end of the barrel so as to bear against the work while the rivet tail is engaged in the recess I0. The barrel, adjacent its front end, is provided with sight openings ill by means of which the workman may center the tail of the rivet in the recess I0, the anvil 6 being slightly retracted for this purpose.

The inner end of the outer anvil 6 is formed with grooves 19 and the outer end of the anvil From the foregoing it will be apparent thatthe tool is adapted to engage the tail end of the rivet while the riveting hammer is being used upon the head of the rivet and the yielding action of the anvils in the handle against the tension of the spring I! will eliminate the shock of the hammer vibration being transmitted to the hand of the workman and will also produce a secondary hammering effect against the tail of the rivet. The tension of the spring I! may be adjusted by means of the outer plug [4.

It is believed the details of construction, advantages and manner of use of the device will be readily understood from the foregoing without further detailed explanation.

Having thus described the invention, what I claim is:

1. A riveting tool comprising a barrel a plurality of anvils slidably mounted in the barrel, one of said anvils being adapted for engaging the tail of a rivet during the riveting operation the other of said anvils having a plurality of separated compartments therein adapted to contain a filler and spring means urging the other anvil in engagement with said one anvil.

2. A riveting tool comprising a barrel, a plural ity of anvils slidably mounted in the barrel, one of said anvils being adapted for engaging the tail of a rivet during the riveting operation, the other of said anvils being hollow and adapted to receive a weight, a tubular extension including a threaded plug detachably secured to the said other anvil and also adapted to receive a weight, and spring means surrounding the extension and engaging the said other anvil to urge the same into engagement with the said one anvil.

3. A riveting tool comprising a barrel, a plurality of anvils slida-bly mounted in'the barrel, one of said anvils being adapted for engaging the tail of a rivet during the riveting operation, the

10 and a coil spring on the guide between said plugs.
