.WESLEY MALVICK, or ERIE, PENNSYLVANIA.

Leners Patent ivo.- 93,213, dazed August 3, 1869.

To all 'whom it may concern Be it known that I, WESLEY MALIcK, of Erie, in

the county of Erie, and State .of Pennsylvania,have

useful Improvements iu Machine and 1 do herebyl declare that the following isa full, true, and exact description of my invention, reference being had to the-accompanying drawings, and the letters of reference marked thereon,

invented new and Figure l isla perspective view. i

Figure 2 is a Jtop view of that portion of my maf' chine denominated the bender. y 'Figure 3 is a side view of a portion of the weldingapparatus. y

Figure 4 Ais a top o r face view of the same, showing the faces of the two quadrant-shaped iron pressers C and D, and showing the position and shape of the male and female dies E and F, (Fig. 3 also shows the form and position of-these dies) Figure 5 is a view of the detached from thebender. v

Figure 6 is a .View of the shears or cutters a and b, with an iron rod, k, in position for being cut.

Figures 7 and 8 are chain-link.. The construction of my machine is as follows: A and B are bed-plates resting on legs or framewerk.

"K is a heavy iron frame in which rest thepressers C and D.

These pressers are usually constructed in the form shown in iigs. 1 and 3, that 'is quadrant-shaped, with a wide face, on which areraised the cogs shown.

They are so placed in the frame K, that their faces press on each other, and the cog's gear, and theA cogwork secures the uniform of the two pressers.

The bearings of these pressers are fitted in boxes,- thenpperone of which, I, is movable by the 'adjusting-screw J.' It is raised or lowered at pleasure,

Athereby giving more or less pressure at the face of the pressers. l

E and E are dies, which are dovetailed into the faces of the pressers C and D, and are removable0 These pressers,

when moved, have an oscillating motion.

They receive their motion by the pitman G, which connects the eccentric H with the presser 1).

This partof' the machine is thrown in and out of gear by the long lever L, whichmovcs the clutch M.

'On the bcd-plateB is fastened the bender, which consists of' tlle'sliding cutter-bar n, the cutters a and b, the finger-bar c and finger o, the friction-wheels c and, l, the gauge d, the claws Z Z, the levers T T and U'U, and the ram Y.-

pins j j on the finger-bar c and finger o,-

thelevers T "l, and also to the cross-bar X, which'is secu'iedto the ram Y. The cutter-bar n and the finger-bar c are attached together, and both receive their motion 'by the pitf man S, whichv connects the eccentric R on the shaft 0 with them, andis attached tethem at the lug j, in which is the slant g.

The claws and ram Z Z and Y receive their motion from the crank-plate V, 'on the .shaft O, by the pitman W, which connects with the raul Y at p.

The manner inwhich my machine is operated isas follows:

Attention being called to ng. 2, the machine is brought to the position indicated, c'. e., with the ram Y drawn back, the claws Z Z opened, -and'the cutter bar u and finger-barv c drawn up. The rod k is then shoved into the gauge d, passing back of the finger o,- (in about the position shown by k, g. 5,) and passing in front ofthe friction-rollers e and l, and then be-4 tween the cutters a and b, resting as seen fig. in 2.

Fig. 6 shows an end view of ythe cutters a and b, with the rod It' in position.

rlhe next move ofthe machine is as follows:

The cutterfbar n and the finger-bar c move iu the direction indicated by the arrow: the cutter?) passes under the cutter a in the manner of shears, and the rod k, being between them, is out in two diagonally. The finger o has by this time .commenced pulling the piece of rod just cut in between thefriction-rollers c and l. This brings the rod intoahout the shape of the ,letter U, when the machine being so timed, the

claws 'Z Z grab the 'extremities of the U-shaped rod,

and draw them together around the. n'ger o, which is elliptical or link-shaped. The rain 'Y then strikes the two ends and Asets them vup close-against the finger o,

whichV gives the rod a perfect linkssliape. The claws and ram, by the action of'thc crank V, draw back, and the' tinger,I on account of the slant y inthe lug j, halts for an instant, and the link falls iioni the nger o, through the hole m in the bed-plate B, to the floor. The rod being 4fed in at au incline to the bed-plate, as shown in iig. Gyand being cut diagonally or scarng, the link, when bent, isv open suine-eut to admitof a link being slipped iu, as seen in fig; .T ,yand is scarfed readyvforwelding, as is seen at c', iig, L

The link thus formed is brought to a welding-heat, and placed with its open ends (e g fr, fig. 7) in the fev maledie'F, on the face of the presser D, and that. portion of the machine is at once thrown into gear by the operator Amovingthelever L' with `his'leg. This brings the two dies together with great force. The pressure thus-exercised and exerted an the link weidsit.

Attention is'called to the form of the dies E and F. F, it will `be noticed, is a. simple female die. It is,

' however, sunk deeper than halt' the thickness of the view, asin fig. 3 at y y y y, a serrate appearance.

, The oiqjcct of this form of construction is, that when the dies are set together, the space in which the link is pressed is below the surface ot' the die 14, whichprevents a lip or bead being formed on the edge of the A shaped as described, and for the purposes set forth.

link by the highly-heated and soft liron being forced out between the faces of the two dies, as would be the case if the two dies were of the form of the die F. By this deviceV the ylink is complet-ely surrounded, 'the points or selrates y y y y reaching down the sides of the groove in the female die F, and entirely preventingany ot' the iron being squashed out by t-he pressure, thus making the link, at the point where it is welded, as round andsmooth as at any other point.

Links, rings, and other similar things can be welded by using diesl constructed in this way, by a. drop-harnnier, in place of thepressersC and D; also bytriphammers and by rollers.

in iig. l, at the points marked h and z' on the presser D and the pitman G, is a pair ot' shears or cutters,

clamps Z Z, rain Y, and friction-rollers e l, all arrangedand operating together as set forth.

2. The combination of the concave dies E and F,

3. The construction and arrangement of the reciprocating yoke Gr, sectors C D, circular frame K, and

provided with the former o upon its end, all substan-v tially as shown and described.

5. The arrangement of the shears ht', respectively,

on the reciprocating stirrup G, and vibratingr sectorG,

as and for thel purposes specified.
