1 Claim. 1

The invention relates to measuring scoops or ladles and has for its object the obtaining of a construction with which a predetermined quantity of granular material may be measured with great accuracy. To this end the invention consists in the construction as hereinafter set forth. The measurement of granular or powdered material such, for instance, as ground cofiee, is frequently accomplished by the use of a spoon or scope and two difierent quantities can be measured, the one level or in line with the edges of the receptacle and the other heaping where the material mounds upward from said edges. For obtaining a level measurement some other instrument must be used to strike off the surplus material. n the other hand, with a heaping measurement the quantity will vary in accordance with the condition of the material as, for instance, the presence of a greater or a lesser amount of moisture.

It is the object of the instant invention to obtain a construction using the level measurement but without the necessity of any auxiliary device for striking the level. This is accomplished by the construction illustrated in the drawings, in which:

Fig. 1 is a plan view of one form of my improved measuring scoop or ladle;

Fig. 2 is a side elevation thereof;

Fig. 3 is a central longitudinal section;

Fig. 4 is a plan View showing a modified construction;

Fig, 5 is a side elevation thereof;

Fig. 6 is a cross section on line 6-6, Fig. 5;

A is the bowl portion of the scoop or ladle which is preferably formed with a nose B and straight sides C and C extending therefrom in tangent relation to the main portion of the bowl and with an included angle therebetween of approximately 90. D is a handle extending from the side of the bowl opposite the nose B. The upper edge of the bowl is in a plane which is also theplane of the upper face of the handle D. E is a wiper bar which as shown in Figs. 1 to 3 is pivotally attached to the handle D by a headed pin F. This wiper bar normally extends clear of the bowl substantially tangent to one side thereof and rests against a stop G projecting upward from the handle. For holding the bar in this position, a torsion spring H is sleeved on the pin F and has its opposite ends anchored respectively to the wiper bar and the handle.

With the construction as described the scoop may be filled by dipping it into the granular material while the parts are in the position shown in Fig. l. The bar E may then be wiped across the upper edge of the bowl by the finger or thumb of the hand grasping the handle engaging a rearwardly extending portion E of said bar. Consequently, all of the material above the plane of the upper edge of the bowl will be swept off leaving an exactly measured quantity in the bowl.

With the construction shown in Figs. 4 to 6, inclusive, instead of using a pivoted wiper bar, a wiper bar I is employed which is formed as an upturned laterally extending flange on a member J resting on the upper face of the handle K. The member J is also provided with an upwardly projecting return bent portion L forming a thumb piece and having a downward extension L passing through a slot K in the handle K to termihate in a cup-shaped portion L The handle K has a depressed tongue portion K on which is sleeved a spring M and the cup-shaped portion L is apertured to slide upon this tOngue against the tension of said spring. A stop pin Q in the handle limits the rearward movement of the member J under the pressure of the spring.

With this modification the bar I is normally in rear of the bowl so that the latter may be filled with the granular material. The operator then presses 0n the portion L by the thumb of the hand grasping the handle and this will force the bar I across the bowl wiping off all surplus material. As soon as pressure is released, the resiliency of the spring M will return the parts to normal position,

What I claim as my invention is:

A measuring scoop or ladle comprising a. bowl having a flat handle integral therewith and projecting rearward therefrom with its upper face flush with the upper edge of the bowl, a tongue struck downward from a center portion of said handle forming a slot therein, said tongue being parallel to the handle in a plane below the same, a wiper bar extending transversely of said handle directly in rear of said bowl and having a rearwardly extending portion with an upwardly extending return bend therein and terminating in a downwardly extending portion passing through said slot, and a coil spring sleeved upon said tongue with its rear end abutting against said downwardly extending portion whereby said upwardly extending return bend may be operated by the thumb or finger of a hand grasping the handle to move said wiper across the upper face of said bowl against the resilient pressure of said spring.
