The two pillar blocks a a supported by a strong basement, carry the shafts b and c
of the superposed profile rollers d and e, the latter of which shafts being vertically
adjustable so as to allow the roller e to be lowered onto the roller d. For this
purpose the bearings ff are adapted to slide between the blocks a a and to be
moved up and down by means of the train of tootbed wheels ghg, pressing screws i i
and hand wheel k. The rollers d and e are set in rapid rotation from the pulley !
by aid of the toothed wheels m m m. The pillar blocks a a carry, adjustably screwed
thereto, the bifurcated support n, shewn in bottom view Fig. 6, having in front a
vertical arm n', on which the slide o is vertically adjustable in a dovetail guiding by
means of a pressing screw p and a hand wheel q. The slide o carries at the bottom
the folding wheel and at the top the adjustable angle piece s, shown in front-side-
and top-view by Fig. 5, whilst it is provided below with a second folding wheel 11.
On the slide bearing of the shaft e the box t is screwed which carries at the top
the horizontal arm u. To the latter are secured by means of set-screws the bows or
forks u carrying the guide pulleys », Figs. 2 and 3º. The slide o has secured
thereto the block o¹ Fig. 1, provided at the bottom with the cutter w, while a second
cutter wl is adjustable in a slot of the front side of the frame. The cutters may also
be replaced by any other convenient device, for instance by a graving tool.
The slide of the frame has at the top a recess a¹ to admit of a free movement
of the rear folding wheel ¹. The guiding ruler z moving in the tube z¹ and held in an
elevated position by the spring 22, serves to guide the hoop y in the said recess, that
is to say to prevent it from inclining inwardly and assuming an uneven position. The
hoop is moreover guided by the cylinders revolvably attached to the side of the frame,
while the roll w below the cutters serves as a support for the double hoop or ring
while being halved.
The improved machine works as follows:
The unfigured hoop y, the intended profile of which is shewn in Fig. 4, is placed
on the lower roller d and, by turning the hand wheel k, the upper roller e and the
guide pulleys are lowered on to the hoop, which is then figured by the rapidly
rotating rollers. Subsequently the wheels rand are slowly lowered by means of the
hand wheel qand fold down the rims y¹ of the hoop projecting over the rollers de Fig. 4.
When the wheels and r¹ arrive at their lowest position, the cutter w is simultaneously
descended onto the hoop, which is thereby pressed energetically between the cutters and
divided into two symmetrical halves, the roll w² affording the required support.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :
In machines for swaging or rolling metallic hoops and rings.
1) The application of a second folding wheel, rollers de with double profile, a
recess and guiding ruler for the purpose of figuring two hoops simultaneously,
substantially as set forth.
2) The application of a pair of cutters ww or any other convenient device for
halving the figured doubled hoop, in combination with the supporting roll 10?,
substantially as set forth.
