THEODOR SMOLINSKY, OF GARY, INDIANA.

WORK-SUPPORT.

Application filed August '7, 1918.

T o all whom t may concern.' g

Be it known that I, Ti-rnonon SMoLINsKY, a subject of the Emperor of Austria, residing at Gary, in the county of Lake and Stat-e of Indiana, have invented certain new and useful Improvements in lVork-Supports, of which the following is a speciiication.

My invention relates to work supports, and has for its primary object the provision of improved means for supporting a metal plate or plates in the various positions necessary for hammering out round kettles and the like. A further object lies in the provision of adjustable features whereby the supporting mechanism of the present invention may be readily adapted to the formation of kettles of various sizes and shapes.

My invention relates also to a novel method of forming Simultaneously a plurality of kettles of identical shape and substantially identical size that may be nested one snugly within the other.

Other objects and advantages of the invention will appear from the following description, taken in conjunction with the accompanying drawings whichforin a part of this specification and illustrate the preferred embodiment ofthe invention.

In the drawings:

Figure 1 is a top plan view of the' work support, showing a metal kettle in practically completed form mounted thereon.`

Fig; 2 is a side elevation thereof, and illustrates in dotted lines a tilted position of the kettle being formed.`

Fig. 3 isv a verlticalcentral section through a plurality of superposed malleable metal plates illustratingone step in the method of.

13, the latter being shown only fragmentally at its lower, striking end which is vertically reciprocated by any suitable means in the bearing. The hammer 13 is positioned centrally above and spaced from the base, and directly beneath it an anvil 14 is removably fixed in the base by, preferably, a tongue Specification of Letters Patent.

and groove connection as maindicated at 15. The upper surface of the anvil is concaved for shaping the particular kettle 16 shown in the drawings, but other anvils differently hollowed may be substituted for the formation beneath hammer 13 of kettles of various shapes and sizes.

A toothed arm 17 projects forwardly from the `base 10 and the lower end of a standard 18 is adapted to rest upon that arm and between any two of the teeth 19 thereof. From each .side of the anvil 14 a substantially horizontal bracket 2l projects forwardly and is do-wnbent at its forward end and bolted to or in any other suitable manner bears upon the base, the rear ends of these brackets being removably bolted to the sides of the anvil as at 22. The brackets 21 are oppositely and horizontally apertured in a plurality of places for the reception of a pivot pin 23 in any pair of apertures 24. A work supporting yoke 25 has its lower ends pivoted upon the two pins 23 and its upper end slanting forwardly and upwardly and pivotally hooked about one of the rungs 26 projecting rearwardly from the standard 1S. The apertures 24 being all forward of the anvil, the concave surface of the anvil being also slanted downwardly from back to front, the meta-l being worked on is always supported partly on the anvil and partly on the two legs of the yoke 25.

In the operation of the work support, the upper end of the yoke is lirst hooked upon one of the lower rungs 26 and the flat plate of metal placed on the anvil and yoke. As the action of the hammer on the anvil dents the plate, the latter-is rotated on a vertical axis by hand and is also tilted as shown in dotted lines in F ig.2 to enable the hammer to beat the metalV into the curvature desired. As the curvature of the plate increases the upper end of the yoke is elevated rung by rung about pivot pins 23 to provide constant support for the work. 1f a large kettle is being made, the standard will be near the forward or outer end of arm 17 and the pivot pins will engage the forward apertures 24; if a small kettle is to be beaten out the lower end of the standard will be positioned nearer the rear end of the arm and the pins will be inserted in apertures nearer the anvil; in Fig. 2 the support is seen adjusted for the formation of a medium sized kettle, and the relation of parts is that assumed when the kettle is practically completed.

Owing to the concave character of the `upper* surface of the anvil and thefact that thetinued action of the hammer increases the curvature of the metal. As this concave surface slants forwardly the yoke aids in preventing dislodgment of -the'work fromthe anvil under them blows of the hammer. It will be seen that the hook 28 on the upper end of the yoke opens downwardly so that thehook is readily shifted from Lone rung 26 to another. The three point lsuspension for the article being beaten out is' found highly useful in the metal beating art where kettles and similar articles weighing from one hundred pounds up are being handled, the -particular form of the support obtained between the two legs of the yoke and the anvil leaving the workv free for 'easyturn ing in any `desired direction.

My improved `method of simultaneously forming-a plurality of kettles at one operation is adapted for use with the above'de`- scribed work supportingapparatus. In that method a number of superposed malleable plates 31 are employed, their edges being substantially coincident. These, as a body, are placed upon a bottom plate 32 of larger diameter, the edge portion ofk the bottom plate being bent upwardly about the `edges of the body of plates as at 33 andclenched down upen the latter as seen at 34- in Figs. 3 and l. The laminated plate thus formed is treated as above describedfor fa single plate by being placed upon the anvil and the yoke 25 and by beating it with hammer 13. Fig. 3 shows the laminated plate after the process of beating it has juststarted; Fig. 4 illustrates a nest of kettles'completed by this process. Then the beatingof the laminated plate is completed, the edge portion 33-34 is removed from the vouter layer 0r plate 32 leaving the several lalninefseparable from each other, this edge portion holding the laminze in fixed relation to each other during the beating operation.

lllhile I have illustrated and described the preferredA embodiment of the' invention, it

will be obvious that one skilled in `the art 1nightmake modications thereof without departing fi'ointhefspirit of the invention. I wish, therefore,not to be restricted to the precise embodiment shown, except in so far as the same is limited in the appended I claim:

1. A'work support, comprising an anvil, a pair of legs pivoted at their lower ends adjacent the anvil, a 'standard upon whichthe uppenends of the legs rest, means on the standard 'permitting adjustment of the legs thereon,` and `means permitting adjustment of the standard." Y

2. A work support `forpow'er v hammers, comprising A`an anvil: positioned beneath the haninfier, a l.pair sof legs pivoted fdrwardly of the anvil onVasubstafntially horizontal axis, and `rmeanspermitting; adjustment of the yfree ends 'of said legs' at' 'various heights with respect to :the anvil.

3.
