Improvements in Rolling Mills.
We, JOHN HOTCHKINS BICKLEY, and JOHN HOTCHKINS BICKLEY, Junior,
both of Dover, in the County of Morris and State of New Jersey, United States of
America, Manufacturers, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
This invention relates to certain new and useful improvements in mills for rolling
hoop and cotton tie iron, and it has for its objects, among others, to provide a mill
for this purpose in which the iron shall be made to repeat itself on both sides of the
mill until the required thickness is obtained, instead of having to be run through
its entire length and then passed back again, and so on, until reduced to the
required thickness as heretofore.
The tongues and grooves of the rolls alternate, thus changing the division of the
rolls upon the irons at each pass. We provide repeaters for turning the iron to
the succeeding groove and aprons for conforming the iron to the succeeding groove.
Adjusting means are provided for holding the aprons up to the rolls. Guides are
also provided for pointing the iron into the groove as the repeater turns it up or
down as the case may be.
Other objects and advantages of the invention will hereinafter appear, and the
novel features thereof will be specifically defined by the appended claims.
The invention is clearly illustrated in the accompanying drawings, which, with
the letters of reference marked thereon, form a part of this Specification, and in
which
Figure 1 is a front view of our improvement.
Fig. 2 is a vertical section through the same from front to rear.
Like letters of reference indicate like parts in both views where they occur.
Referring now to the details of the drawings by letter, A designates the housings
of the mill, and B the rolls mounted centrally over each other, as seen best in
Fig. 2. The rolls are capable of adjustment vertically by means of the screws C C¹
which are tapped through the tops of the housings as shown. The tongues D and
the grooves of the rolls are arranged to alternate as shown in Fig. 1, thus
changing the division of the rolls upon the iron at each pass. Motion is imparted
to the rolls in any suitable manner. As the details of adjustment of the rolls and
the manner of revolving them forms no part of the present invention, these features
have not been fully illustrated nor dwelt upon in the description.
Fare repeaters for turning the iron to the succeeding groove and F1 are rests for
supporting the said repeaters, the rests being adjustably held by the weighted
levers E fuleruned on the shaft and connected with the repeaters by the
rods F.
Gare aprons for conforming the iron to the succeeding groove, the aprons being
carried by the rest bars G which are rendered adjustable by the screws Gas
shown, for keeping the aprons up to the rolls.

page_text: His a guide plate set at a slight incline downward as seen in Fig. 2, and Hare
guides on this guide-plate as seen in Fig. 1.
I, are guides curved as shown in Fig. 1.
These guides are secured on the faces
of the aprons, and arranged at an incline, the opposite faces of the said guides being
formed in the shape of a section of spiral, the spirals upon the two faces extending
in opposite directions, as seen in Fig. 1. These guides I, serve to guide the iron
into the groove, as the repeaters turn the iron up or down as the case may be.
The operation is as follows: The iron is placed into the rolls at the point X or
groove, and is then made to take a serpentine course by the repeaters F and
guides 1, to the next groove Y at the bottom, and so continues to repeat itself,
being guided up and down and into the succeeding grooves by the repeaters and
grooves on both sides of the mill until the required thickness has been obtained.
The operation is continuous, the bars do not have to be taken out and run back
through the mill; this is automatically performed by the guides and repeaters.
Various modifications in detail may be resorted to without departing from the
spirit of the invention or sacrificing any of its advantages.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the saune is to be performed, we declare that what we
claim is
1. The process herein described of forming band ties, which consists in alternately
changing the division of the rolls on the iron at each pass, substantially as
specified.
2. The herein described process of rolling iron, which consists in automatically
changing the division of the rolls on the iron, at each pass, as set forth.
3. The process herein described of rolling metal which consists in automatically
alternately changing the course of the iron at each pass and guiding it into the
succeeding groove, as set forth.
4. The combination with the "olls, of the repeaters and the grooved guides, as set
forth.
5. The combination with the rolls and the repeaters, of the grooved guides
having their opposite faces oppositely formed in serpentine shape, as set forth.
6. The combination with the rolls and the repeaters, of the curved guides and
the guides H' near the terminus thereof, as set forth.
7. The combination with the rolls and the repeaters, of the curved guides with
their opposite faces oppositely curved in spiral form, and the aprons, as set forth.
8. The combination with the rolls and the repeaters, of the curved guides, the
adjustable aprons, and the guides H' substantially as specified.
9. The combination with the rolls and the repeaters, of the curved guides with
spiral faces, the guide-plate and its guides, the aprons and the means for keeping
the aprons up to the rolls, substantially as specified.
