UNITED STATES PATENT OFFICE LADLING DEVICE Rex M. Shultz, Ventura, Calif.
Application October 27, 1947, Serial No. 782,374
1 Claim. 1
This invention relates to improvements in a ladling device and more particularly to a device such as embodied in Patent No. 2,171,606, which issued September 5, 1939.
It is a particular object of the invention to provide a handle for the device with a grip of a character to protect the hand of the user against the extreme cold which radiates from the type of handle now generally employed and more particularly when the device is in constant use.
A still further object of the invention is to provide a ladling device wherein the handle is of a distinguishing color to identify its particular size.
Another object of the invention is to provide a ladling device of a type wherein the head portion and handle portion are hollow to provide for a circulation therein of a tempering liquid and wherein a grip is mounted on the handle portion in a manner to prevent disruption of the seal for the internal chamber formed by the hollow head portion and handle portion.
The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved ladling device whereby certain advantages are attained, as will be hereinafter more fully set forth.
In order that my invention may be better understood, I will now proceed to describe thesame with reference to the accompanying drawings, wherein:
Figure 1 is a longitudinal section-a1 view taken through a ladle constructed in accordance with an embodiment of the invention;
Figure 2 is a sectional view taken substantially on the line 22 of Figure 1.
As comprised in the accompanying drawing, S denotes a scoop of a, type for serving out ice cream and the like and which comprises a head portion I and a neck portion 2. The neck portion 2 is continued by a handle portion 3 of desired length and which portion 3 has its wall reduced in thickness from without whereby is provided, at the junction of the portions 2 and 3, an outwardly and rearwardly facing shoulder A. This shoulder 4 surround the handle portion 3 and is inwardly tapered or undercut on a desired angle.
The head portion I is hollow as are also the neck portion 2 and the handle portion 3. The neck portion 2 is in communication with the interior of the head portion I, and the registering bores b and 5 of the portions 2 and 3, respectively, are in communication and of material radii.
The outer end of the bore 5 of the handle portion 3 is initially open and fittmg in said open end portion is a plug or stopper 6. When applied, the outer face of the plug or stopper 6 is substantially flush with the open or outer end of the handle portion 3.
Substantially midway of the front wall 1 and the rear wall 8 of the head portion l is a baflie 0 which extends entirely across the portion I and which baiile l2 lengthwise of the device is disposed on such curvature as determined by the design of the head portion i. The baffle 9 is of a length to extend from a point spaced from but in close proximity to the outer end of the head portion i to a point slightly inwardly of the neck portion 2.
The head portion I, neck portion 2, and handle portion 3, are filled with a solution having a low freezing point such, for example, as a solution of calcium chloride and which solution preferably has a freezing point of approximately 15 F. below zero.
The fluid is introduced within the device through the initially open end of the handle portion 3 and after which the plug or stopper 6 is applied. In connection "with this plug or stopper is preferably used a cement seal or the like.
In the use of the scoop, it will be normally held in a more or less vertical position in order to fill the bowl with ice cream or an other frozen material, so that the forward edge [0 will first be forced into the material, and as the scoop is moved in an arcuate path or toward a horizontal position, the body of cream will be rolled into the bowl of the scoop. This will effect a chilling of the fluid immediately contacting the bottom of the bowl and as the scoop is raised from the ice cream containing receptacle for the purpose of transferring the ball of ice cream to a dish or cone, it will be apparent that there will be a movement of the fluid within the scoop due to the convection current established because of the diiferences between the temperature of the fluid at the bowl and that in the rear part of the scoop or the neck portion 2. The colder fluid will tend to flow along the passage H to the rear of the scoop and the warmer fluid from the rear of the neck portion will move forwardly and come into contact with the bowl so that it will give up some of its heat to the material contained therein and thus prevent adhesion of the material to the extent that it can be readily removed from the bowl.
Associated with the handle portion 3, is a hand grip H, of plastic material and which is closed at its outer end. The hand grip I-I snugly fits on the handle portion 3 and is applied while not and the outer closed end is arranged outwardly of the handle portion 3. The grip H is of such dimensions as to have the inner face a of its outer end in close engagement with the outer end of the handle portion 3 and the outer face of the applied plug or stopper 6, and with its inner end in close interfitting contact with the undercut shoulder 4.
Extending outwardly from the periphery of the handle portion 3 at points spaced lengthwise thereof and therearound are the inwardly inclined barbs or projections I2 which engage within the wall of the bore I4 of the hand grip H, when applied in its heated condition. After the hand grip H has been properly fitted on the handle portion 3, and when hot, it is given .a slight turn around the handle portion 3 which assures the hand grip H, being firmly .held in position.
The hand grip H serves to protect the hands of the user when the ladle device is subjected to more or less steady use and the hand grip H is of a specific color to provide means whereby the particular ladle device can be easily identifled in accordance with its size whereby time and annoyance is saved in selecting a ladle of a desired size. It quite often happens that the average fountain uses a vessel such as a two quart ice cream can containing water where the dippers stand with bowlsor head portions submerged and handles exposed as well as some later fountains which have such a place in the unit. In either case the operator using my ladle devices with various colored handles can quickly distinguish the size he wishes to use.
The hand grip H also provides an eflective means for eliminating accidental withdrawal or removal of the plug or stopperfi.
From the foregoing description it is though to be obvious that a ladling device constructed in i accordance with my invention is particularly -'well adapted for use by reason of the convenience and facility with which it maybe assembled and operated.
A ladlingdevice comprising, in a single unit, a head portion, a neck portion extending therefrom and a handle portion forming an integral continuation of the neck portion, the neck portion and handle portion being tubular and the head portion being hollow and in communication with the tubular neck portion, said handle portion being of circular external cross section and of a diameter materially less than the outside diameter of the neck portion whereby there is formed a shoulder at the line of joinder between the neck portion and the handle portion, the outer end of the handle portion being initially open to facilitate the introductionof a low freezing =point1fluid with which the :portions are filled, a plug closing the open outer end of the handle portion, a hand grip in the form of a tubular sheath closed at one end having the said handle portion extended thereinto from the other end thereof whereby the said closed end of the sheath completely covers the outer end of th handle portionand the plug therein and the said other end of the sheath abuts said shoulder, the overall diameter of the sheath being approximately the same as the outside diameter of the neck portion, the said shoulder being undercut, and pointed spur members forming an integral part of the said handle portion and directed toward said shoulder for maintaining the said other end of the sheath in firm engagement against the undercutsurface of the shoulder whereby a tight joint is established between the sheath and the shoulder face to provide a smooth continuous outer surface between the outer face of the hand grip and neck portion.
