RIVETING AEPARA'IUS.

Application filed July 29, 1924-.

To all whom it may concern:

Be it known that WILLIAM G. LnAzAR, a citizen. of the United States of America, re-

, sidin at. Kerrville, in the county of Kerr and tate of Texas, has-invented new and useful Improvements in Riveting Apparatus, of which the following is a specification. fiIt is a purpose of the present invention to provide, in a riveting apparatus, a construction particularly adapted for riveting arms upon crank cases, especially those of the Ford type, and in carrying this process into elfect theinvention includes a riveting block with means for fastening themsame on a bench or a horse, whereby the crank case may be placed so that, when the rivets which are to securethe arms to the crank case engage with thezblock', in' iproved clamps are used to. fasten: the crank-case in position, subsequently towhicha mechanic may proceedl to heat the rivets with a torch and set them with a riveting-setor hammer.

T -It is to be understoodthat the particulars herein given are in no .v-say. limitative and that, whilestill keepingwithin thescope of the invention, any desired modifications of:

detail .and- .desired' proportions may be: made in. the apparatus according to the circumstances; I 7:, r

I vThe inventioncomprises further features and combinations otpartsto be hereinafter set forth, shown claimed;

In the drawings: I

Figure 1 is a view of the improved riveting. app'aratus constructed in accordance with the invention and illustrating a crank case in position thereonfor' riveting the arms in position.

Figure 2 is a central vertical sectional view of the invention, illustrating how the rivets engage with the riveting block and how the clamps are applied.

Figure 3 is a detail view block.

Figure 4 is a detail view of a portion of the riveting block and the support 16.

Figure 5 is a detail view of a portion of the support 16 and the holder 20.

Referring to the drawings, 1 designates the riveting block which is provided with a pair of projections 2 and 3 which are cesigned to enter openings 4 and 5 of corresponding size to the diameter of the projections, said openings being formed in a bench,

The clamp 11 is then disposed in position, the base end of which engages in the depression or seat 7 and tastened with the transverse pin. The clamping screw is then tightened so that its foot may tighten against the crank case and arm, fastening them to the riveting block. Subsequent to this, the mechanic is at liberty to proceed with the usual acetylene torch :ior the purpose of heating the rivets, after which they may be headed with a conven- A single operator or mechanic may easily operate the apparatus without assistance.

The invention having been setforth, what is claimed is:

1. A riveting apparatus for riveting arms on crank cases, the same comprising a riveting block provided with means for holding it ona bench or other support, a supporting member carried by the riveting block and having a laterally projecting arm, a holder suspended from said arm and adapted to support a crank case at a point remote from the riveting block, and a clamp operatively supported on the riveting block for bearing engagement upon a crank case arm and holding it in contact with the crankcase and the latter in contact with the riveting block.

2. A riveting apparatus for riveting arms on crank cases, the same comprising a riveting block provided with means for holding it on a bench or other support, a supporting nemher carried by the riveting block and having a laterally projecting arm, a holder suspended from said arm and adapted to support a crank case. at a point remote from the riveting block, and a clamp operatively supported on the riveting block for hearing engagement upon a crank case arm and holding it in contact with the crank case and the latter in contact with the riveting block,

said clamp comprising a goose-neck arm detachably engaged in a seat on the riveting block.

3. A riveting apparatus for riveting arms on crank cases, the same comprising a riveting block provided with means for holding it on a bench or other support, a supporting member carried by the riveting block and having a laterally projecting arm, a holder suspended from said arm and adapted to support a crank case at a point remote from the riveting block, and a clamp operatively supported on the riveting block for hearing engagement upon a crank case arm and holding it in contact with the crank case and the latter in contact with the rivetingblock, said support comprisinga bar having a U- shaped extremity disposed at right angles to the projecting arm, tremity straddling and engaging a recess in the riveting block.

4. A rivetingapparatus for riveting arms on crank cases, the same comprising a riveting block provided with means for holding it on a bench or other support, a supporting member carried by the riveting block and having a laterally projecting arm, a holder suspended from said arm and adapted to support a crank case at a point remote from the riveting block, and a'clamp operatively supported on the riveting block for bearing engagement upon a crank case arm and hold ing it in contact with the crank case and the latter in contact with the riveting block, said support comprising a bar having a U- shaped extremity disposed at right angles to,

the projecting arm, said U-shaped extremity straddling and engaging a recess in the riveting block, and the holder being suspended from the arm and movable longitudinally therealong. i

In testimony whereof he affixes his signature.
