RlVETlN G-MACHINE.

SPECIFICATION forming part of Letters Patent No. 543,324, dated July 23, 1895.

Application filed March 23, 1893. Serial No. 467,269. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL M. VAUOLAIN, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented an Improved Riveting-Machine, of which the following is a specification.

The object of my invention is to so construct a riveting-machine that a locomotiveboiler can be riveted entirely by the machine as close together as possible, as shown by dotted lines in' Fig. 1, and the riveting-head is usually made fiat on top and the boiler is hung .in such a manner that the fire-box section will swing over the head B instead of under it, as shown in the drawings. This arrangement necessitates the readjustment of the boiler in many cases three or four times, and then a number of the rivets have to be headed by hand. The hanging of the boiler with the fire-box uppermost prevents the operator seeing the greater portion of the rivets, as they are adjusted and riveted without stooping,

'and consequently several of the rivets are headed at random.

By my invention the boiler can be suspended as shown in Fig. 2, and every rivet in the trunk portion as well as the fire-boz'c portion can be seen by the operator and can be properlyriveted without readjustment.

A is a standard secured to another standard B by tie-bolts c. A spacing-block O is placed between the two standards at the base so as to give sufficient space for the article to be riveted to swingjin. The lower portions of the standards are mounted in a suitable foundation, asshown in Fig. 1'.

Secured to the plate or. of the standard A is the riveting-head 'D, the portion D of whichprojects over the space between the two stand having suitable pipes and connections at-,

tached to the pressure mechanism; but it will be understood that mechanical riveting mechanism may be used without departing from my invention.

The anvil bis secured to the standardB in any suitable manner and in line with the plunger 61.

-As shown in Fig. 2, the locomotive-boiler is arrangedin position so that the riveter can rivet the joint between the fire-box and the trunk of the boiler, the fire-box section being in the space under the overhanging portion D of the head and between the two standards A and B. By hanging the boiler in this manner the operator can see every rivet as it is headed without stooping. Consequently the rivets can be placed in position more quickly and the head of each rivet properly made.

I do not wish to limit myself to the construction ofthe lower portion of" theriveter, as shown in the drawings, as this construction may be modified without departing from my invention.

I claim as my invention- The combination of the standards'A and B arranged a distance apart to allow the fire box of a locomotive boiler to swing between them, a spacing block 0 mounted between the standards, a bolt. securing the standards together, an anvil on the standard 13, a riveting head D on the standard A and overhanging the space between the standards A and B to a point near the anvil, riveting mechanism in said head, the overhanging portion ofthe head being fiat on the under side, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

SAMUEL M. VAUOLAIN.
