page_text: I, BERNARD MCKIERNAN, of 42, South San Joaquin Street in the City of
Stockton, in the County of San Joaquin, and State of California, United States
of America, Shoe Manufacturer, do hereby declare the nature of this invention to
be as follows:-
This invention is an improvement in weighing-scoops designed for its sim-
plicity and durability of construction, and efficiency of operation, and by the
employment of which the articles gathered up are instantaneously and auto-
matically weighed, thereby saving loss of time in transferring the substance to
independent scales.
I have made provision for the supporting of the filled scoop in a vertical
position when occasion requires, while in carrying out the above prime results
I have provided certain details of construction which add greatly to the efficiency
of the complete device.
Secured to the centre of the closed bottom of the scoop is a hollow cylindrical
stem, which latter is loosely encircled by a cylindrical handle.
Secured to the stem and projecting through a longitudinal slot in the handle,
is an indicating hand which travels over a series of graduations for the purpose
of registering the load in the scoop. Within the stem is a tension spring, the
upper extremity of which is secured to a stationary rod projecting through the
handle, while its lower end is adjustably secured to the lower extremity of the
stem.
As a suitable support for the device, I have constructed a cap with diverging
legs, which is intended to removably fit over and cover the lower end of the
cylindrical handle.
By means of a suitable catch, the scoop and handle and their connecting
parts may be retained in a relatively rigid position, and the tension on the
weighing spring, when it is desired to use the scoop independent of the weighing
mechanism, thereby relieved.
As the catch is pressed inward and released, the scoop and contents exert a
tensile force on the spring, while the pointer indicates the amount of that force
and consequently the weight of the contents of the scoop.

COMPLETE SPECIFICATION.

page_text: facturer, 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 is an improvement in weighing scoops designed for its sim-
plicity and durability of construction, and efficiency of operation, and by the
employment of which the articles gathered up are instantaneously and auto-
matically weighed, thereby saving loss of time in transferring the substance to
independent scales.
Besides making provision for the supporting of the filled scoop in a vertical
position when occasion requires, I have provided certain details of construction.
In the accompanying drawings in which similar letters of reference designate
corresponding parts:-
Figure 1 is a side elevation of the complete device showing a portion of the
cylindrical handle broken away to expose the interior part.
Figure 2 is a longitudinal section of the handle taken in a direction at right
angles to that shown in Figure 1.
Referring now to the above views by letter, A represents an ordinarily formed
scoop having a closed tapered bottom and provided with a series of marks B on
its vertical face to indicate the volume of its contents.
Secured to the centre of the closed bottom of the scoop is the stem C which
latter is loosely encircled by a cylindrical handle D.
Pivoted to the interior of the cylindrical handle D, and similarly secured to
the stem C are the twin parallel links F, F¹.
Pivoted to the lower link F¹ and engaging with a small pinion G is the rack H.
Secured to this pinion G, which is operated by the vertical movement of the
stem C is the indicating hand I which is adapted to travel over a series of
graduations J for the purpose of registering the load in the scoop.
Within the handle D and secured to a rod which is in turn fastened to the
lower link F is the tension spring K. the upper extremity of which terminates
in the rod I which projects through the handle and is engaged by an adjustable
thumb nut M.
By means of the pivoted catch N which is adapted to engage with the notch O
in the stem C, the scoop and handle and their connecting parts may be retained
in a relatively rigid position, and the tension on the weighing spring, when it
is desired to use the scoop independent of the weighing mechanism, thereby
relieved.
As the catch is pressed inward and released, the scoop and contents exert a
tensile force on the spring, while the pointer indicates the amount of that
force and consequently the weight of the contents of the scoop.
In order to give a practical value to the device I have shown minor details
of construction, such as the small spring (a) which is adapted to keep the rack H
in close engagement with the pinion G, and the friction wheels (6) which keep
the stem in a vertical position, but these I lay no particular claim to, as other
mechanical equivalents can be substituted to accomplish the same ends.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1-In combination with a scoop and handle, a stem projecting from said
scoop and encircled by said handle, said stem being connected to said handle by
means of twin parallel links and a tension spring connected to said handle
and brought in tension by the vertical movement of said stem, and means for
indicating the tension on said spring, substantially as set forth.
2 The combination with a scoop and handle, of a tension spring carried by
said handle, a projection of said scoop, said projection being connected to said

page_text: handle by means of parallel pivoted links, and means for indicating the tension
on said spring, substantially as set forth.
3-The combination with a scoop and handle, a spring connecting said scoop
to said handle, means for indicating the tension on said spring, and an adjust-
able catch adapted to lock said scoop to said handle, substantially as set forth.
Dated this 25th day of August 1899.
