SPECIFICATION forming part of Letters Patent No. 609,479, dated August 23, 1898.

Application tiled October 7,1896. `Serial No. 608,150. (No model.)

To all whom. it may concern,.-

Be it known that I, JOSEPH W. THOMPSON,

Aof Salem, in the county of Columbiana and State of Ohio, have invented a certain new and useful Improvement in Riveting-Machines, of which improvement the following is a speciiication.

The object of my invention is to provide an appliance for eyeleting or riveting together sheets or strips of leather, pasteboard, or other comparatively soft material or fabric which shall be of simple and inexpensive construction and in the operation of which the rivet shall be effectively protected against displacement.

The improvement claimed is hereinafter fully set forth.

In the accompanyingdrawings, Figure lis a side view, partly in section, of a rivetingmachine embodying my invention, the movable parts being shown in the positions occupied when in readiness for operation; Fig. 2, a similar view with the parts in the positions occupied at the conclusion of the operation; Fig. 3, a horizontal section at the line of Fig. l; and Figs. t and 5, vertical central sections, on an enlarged scale, through the lower right-hand portion of the machine,

l showing the parts in positions corresponding with Figs. 1 and 2, respectively.

In the practice of my invention I provide a frame or body A1, which may be connected to any suitable base or support 2 and which is recessed or cut away on the side nearest the operative mechanism for the reception of the material a to beriveted and of members of said operative mechanism. An operating-lever 3, which is bifurcated at and adjacent to its inner end to clear a movable plunger 5, is pivoted to the upper portion of the frame 1 bya pin 4. The plunger 5 is iitted to reciprocate vertically in a boss or annular guide 6 on the frame and is externally threaded at and adjacent to its lower 4end (which is properly formed to split and turn over a rivet) to `engage a cylindrical hub or boss 7 on the end of the upper arm of a` U -shaped carrier 8, having a corresponding hub or boss 9 on the end of its lower arm in line axially with the boss 7. The operating-lever 3 is coupled to the carrier 8 by links 10, fitting pins 11, projecting laterally from the operating-lever, and pins 12, similarly projecting fromv the hub 7 of the upper arm of the carrier 8.

An anvil 13 is securedto the bottom of the frame 1 in line axially with the line of traverse of the plunger 3, and the lower boss 9 of the carrier 8 is bored out to tit truly around the anvil 13. Vhen in position for operation, as shown in Figs. 1 and 4., the carrier, through the cylindrical passage 14. of its boss 9, forms a receptacle and guard for the rivet b, the

' head of which is set upon the top of the anvil 13, and the rivet is protected from displacement in theoperation of the machine by said receptacle, which does not pass clear of its head until after it has penetrated the material to be riveted.

The threaded connection of the plunger and carrier enables the plunger to be adjusted'to suit different thicknesses of material, as desired, and after adjustment the carrier and plunger form a rigid structure, which is accurately guided in its upward and downward movements by the bearing of the plunger in the boss 6 of theframe and the sliding tit of thelower boss 9 of the carrier on the anvil. The recess or space between the arms of the carrier admits of the requisite projection of the material'on the inside of the axial line of the plunger and anvil.

In operation the rivet l) is placed with its `head on the top of the anvil 13, and the piece I claim as my invention and desire to secure 1. In a riveting-machine, the combination, substantially as set forth, of an anvil, a plunger which is movable in line therewith, and a rivet-guard connected to and movable with the plunger, and guided on the anvil.

In a riveting-machine, the combination, substantially as set forth, of an anvil, a p lunger which is movable in line therewith, aXed guide for said plunger, and a rivet-gu ard con- IOO neeted to and movable with the plunger, and arms connected to the plunger and having :t guided on the anvil. passage through its opposite arm which ts 1o 3. In a riveting-machine, the combination, freely around the anvil, and links coupling substantially as set forth, of a frame or body, the carrier and operating-lever.
