I, WILLIAM NYE WEEDEN, residing at New Bedford, in the County of Bristol and
State of Massachusetts, one of the United States of America, Gentleman, 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:-
Referring to the Drawings:
Figure 1, is a perspective view of the core of my arbor.
Figure 2, is a like view of the blank prepared for forming the body of the arbor.
Figure 3, is a perspective view of said blank after having passed through the
preliminary dies.
Figure 4, is a like view of the core and body blank when combined for the action
of the closing dies.
Figure 5, is a perspective view of said parts after the action of the closing dies.
Figure 6, is a like view of the same after having passed through the drawing
dies, and
Figure 7, is a perspective view of the completed arbor after having a pinion secured
in place thereon.
Tetters of like name and kind refer to like parts in each of the figures.
The design of my invention is to enable arbors for watches, clocks, etc., to be more
easily and cheaply constructed than has heretofore been practicable, and to this end
said invention-
Consists principally, in the method employed in manufacturing arbors by forming

page_text: a core or centre from a straight rod of metal and forming thereon a body by bending
a plate of sheet metal around and causing it to embrace said core, substantially as
and for the purpose hereinafter specified.
It consists further, in the method employed in manufacturing arbors by forming a
core or centre from a straight rod of metal, then forming thereon a body by bending
a plate of sheet metal around the core, and lastly compressing the body closely upon
said core by the action of a drawing die, substantially as and for the
herein-
after shown.
purpose
It consists further, as a new article of manufacture in an arbor which is
composed of a straight, round core or centre and a super-imposed body made of
sheet metal, substantially as and for the purpose hereinafter set forth.
It consists further, as a new article of manufacture in an arbor which has its
centre and pivots formed by a straight, round piece of metal that is bent around and
caused to closely embrace said centre, substantially as and for the purposo hereinafter
shown.
In the carrying of my invention into practice, I construct my arbor from a
central part or core, A, and an external part or body, B. Said core is made by
cutting from steel wire having a diameter suitable for the pivots of the arbor,
a pieco which has the required longth, and then rounding and smoothing its
ends by any suitable means preferably by the operation commonly known as
tumbling."
«
For the body, B, I take a rectangular piece of sheet metal which has a pre-
determined thickness, a length equal to the distance between the movement plates
(if intended for use in a watch or clock) and a width equal to the circumferential
length of the core, A, and by means of suitable dies give to said blank the U-shape
seen in Figure 3.
Said core is now placed in position within said body blank, as shown in Figure 4,
and by the action of dios, the latter is closed down upon and caused to embrace the
former, as seen in Figure 5.
The body, B, is next passed through a drawing die which by its action closes the
metal firmly upon the core, A, gives to said body the exact diameter required and
leaves the surface in a highly polished state.
The arbor thus constructed is complete, the projecting onds of its core forming
pivots and the ends of its body bearing shoulders and is adapted to receive a piuion,
as seen in Figure 7, or to be used in any manner or for any purpose for which
ordinary arbors are employed. For most purposes said shoulders will be sufficiently
accurate as left by the dies, but if necessary they may be dressed off in a lathe at a
trifling cost.
While my arbor is in all respects equal to those made from a solid piece of metal,
it can be manufactured for a fraction of the cost of the latter.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declaro that what I
claim is :-
1. The method employed in manufacturing arbors, which consists in forming a
core or centre from a straight rod of metal and forming thereon a body by bending
a plate of sheet metal around and causing it to embrace said core, substantially as
and for the purpose specified.
2. The method employed in manufacturing arbors, which consists in forming a
core or centre from a straight rod of metal, then forming thereon a body by bending
a plate of sheet metal around the core and lastly compressing the body closely upon
said core by the action of a drawing die, substantially as and for the purpose
shown.
3. As a new article of manufacture an arbor which is composed of a straight

page_text: round core or centre, and a super-imposed body made of sheet metal, substantially
as and for the purpose set forth.
4. As a new article of manufacture an arbor which has its centre and pivots formed
by a straight, round piece of metal and its body formed by a plate of sheet metal that
is bent around and caused to closely embrace said centre, substantially as and for the
purpose shown.
Dated this 31st day of July 1888.
