COMPLETE SPECIFICATION filed by the said Patrick Lennox at the
Office of the Commissioners of Patents, with his Petition and
Declaration, on the 24th November 1870, pursuant to the 9th
Section of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PATRICK
LENNOX, of Lynn, in the County of Essex, and State of Massachusetts,
United States of America, send greeting.
WHEREAS I am in possession of an Invention of "A COMBINATION
OF INSTRUMENTALITIES FOR IMPARTING HORIZONTAL RECIPROCATING MOVEMENTS TO
▲ PENDULOUS ROD OR SUSPENSORY," and have petitioned Her Majesty to
grant unto me, my executors, administrators, and assigns, Her Royal
Letters Patent for the same, and have made solemn Declaration that
I am the first and true Inventor thereof.
NOW KNOW YE, that I, the said Patrick Lennox, do hereby declare
that the following Complete Specification, under my hand and seal,

page_text: fully describes and ascertains the nature of the said Invention, and in
what manner the same is to be performed, in and by the following
statement, taken in connection with the accompanying Drawings, in
which Figure 1 is a perspective view; and Figure 2, a vertical, central,
and longitudinal section of my said Invention; Figure 3, a vertical and
transverse section thereof.
One object of this Invention is to obtain such a motion of the
beaming or sleeking tool. of leather dressing machines as shall enable
such tool to travel over at one traverse a much greater area of hide
than can be possible with an object which moves in an arc of a circle,
the peculiar movement which I obtain by my Invention being a very
beneficial one for hide beaming machines especially.
Another object I have had in view in originating this Invention is to
avoid the complexity of parts which now attaches to machines of like
character, as well as to obtain great strength and stability.
A third object of this Invention is to greatly simplify the con--
struction of the car which supports the hide, as well as to lessen the
number of movements of the same, which is now unavoidable in
manipulating a hidě or skin, since such car at present must be provided
with a clamp or other means of confining the hide to it while being
operated upon.
My present Invention obviates this necessity, owing to the adoption
of two beaming or sleeking tools dually arranged, and striking out in
opposite directions from a given centre and each traversing the hide
with like effect.
The necessity of providing some means of enabling the operating
tablet of the movable car to accommodate itself to the pendulous
motions of the suspensory of the beaming tool in machines at present
in use renders the construction of such car expensive and complicated
in comparison with that required with my present Invention.
This Invention consists, mainly, in supporting a pendulous or
- vibrating rod by means of a pin and slot connection, in such manner as
to admit of its vertical as well as swinging reciprocations, as well as in
combining with the rod.or suspensory thus applied and guided a pin or
stud projecting laterally from it and extending into a sectoral or curved
slot, formed in the adjacent portion of the frame upon which the
swinging rod is supported, or from which it is suspended, the contour
and disposition of such slot being such as to produce, in connection

page_text: with the peculiar mode of uniting the rod and beaming tool, alternate
depressions of such rod and tool as they approach the limit of their
traverse, whereby to counteract the tendency of the tool to rise from
off the hide at such times as it passes a perpendicular line in either
direction.
And this Invention consists, secondly, in combining together, and so
as to operate simultaneously and in opposite directions upon a skin, two
beaming tools, by which means no extraneous device is necessary to
secure the skin to the tablet under the action of such tools.
In the Drawings accompanying this Specification, and which illustrate
my Invention, A denotes a curved or sloping goose-neck or crane of
proper form and strength to sustain the operative parts of the mechanism
hereafter alluded to, such crane projecting and rising at an angle of
thirty degrees or thereabouts from a base or supporting frame or
standard B. The crane A is open or slotted, and I dispose between the
upper ends of its side plates a' or b', a swinging rod or beam D, such
rod being retained in its proper relationship to the crane by a horizontal
pin b, which extends through a slot or orifice a formed in its upper
part, the two ends of the pin or fulcrum being made fast to the crane
and its diameter being such as to nearly if not quite equal that of the
slot a.
This mode of supporting or guiding the extreme upper end of
the suspensory or rod D. permits of slight vertical movements of the
same and of extended vibrations of its lower end and of the beaming
tool pivoted thereat. E, E, represent two curved or sectoral slots or
channels formed within or suitably applied to the inner face of the
upper end of each side plate of the crane A, and immediately below
the pin before mentioned, such slots constituting the means of
suspension proper of the rod D through the aid of a pair of trunnions
or lateral journals d, d, projecting from opposite sides of the rod and
extending into them, as shown in Figure 3 of the accompanying
Drawings. The curved slots E, E, are counterparts of each other in
form and disposition, and are practically of uniform diameter throughout
their length, and their character and relationship to the crane and
bar or rod D are such that upon a vibratory motion being imparted to
the said rod by means herein-after stated the trunnions guided by such
slots and executing a curved movement shall effect a sliding depression
of the rod as it approaches the extreme of its traverse in either
direction, the combined notion thus imparted to the rod being such as

page_text: to counteract the elevating tendency of its vibrations, which would
otherwise force it to move in a curved path, and enabling me to obtain
a horizontal rectilinear movement of the beaming tool carried by the
suspensory D.
I do not consider it necessary to give herein the exact contour of
the slots E, E, as this is demonstrated only by a geometrical calculation
or by practical experiments varying with circumstances. I would state,
however, that if the changeable fulcrum bis fixed to or projected from
the suspensory D, and the slot a formed in the crane A, (or reverse of
the disposition shown in the Drawings), the form of each slot E would
be a portion of an ellipse, the two halves of the slot being of like shape.
The carrier to which the beaming or reducing tool is affixed, when
the machine is in operation, is shown at e in the Drawings as pivoted
at its upper end to the lower extremity of the suspensory D, a pitman F
being in turn pivoted to about the centre of the said carrier e, while
the opposite end of such pitman is pivoted to the wrist pin of a crank
or wheel G, duly supported and mounted upon a shaft H, which revolves
in bearings on a bracket I affixed to one side of the frame B. The
mode of pivoting the tool carrier e to the suspensory D is such that
during a traverse of the two (at the hands of the revolving crank or
wheel G) in one direction the beaming tool shall be elevated from off
the surface of the skin which is being treated, while during the next
'succeeding or return traverse such tool shall be brought forcibly in
contact with the surface of the skin.
.
It may be found in practice that various modifications of the above-
described mode of suspending and operating the rod D may be effected
without changing or departing from the spirit of my Invention, and that
equivalents for the pin and slot connection in combination with the
curved guides E, E, may be employed to effect like results.
CLAIM.
I claim the herein described improvements in general and in detail.
