Parana MEASURING DEVICE.

Specification of Letters Patent.

Patented July 11, 1922.

Application filed March 4, 1920. Serial Itl'o. 363,352.

To all whom it may concern:

Be it known that I, EMORY HAMMETT Loni), citizen of the'United States,'residing at Washington, District of Columbia, have invented certain new and useful Improvements in Measuring Devices, of which the following is a specification.

The present invention relates, primarily, to improvements in measuring devices and, more particularly, to an improved device designed for use in-handling butter, lard, ice cream, etc, and wherein the material handled can be measured for instance, in'one pound quantities, provision being made to compensate for the varying consistency of the material handled due to variations in temperature.

The principal object of the invention is to provide a light and durable device of the above character which may be produced in diiferent' sizes, for instance, one and two pound quantities, to supplant the ordinary paddle used in handling butter, lard, etc., and which uponbeing thrust into the material in practically the same manner as the ordinary paddle will gather only a certain quantity of the material, one or two pounds according to the size of the device thus eliminating a second measuring of the material as would be the case if the ordinary paddle were used.

A further object of my invention is to provide means for varying the capacity of the container so as to compensate for the varying consistency of the material handled due to differences in temperature, it being well known that material such as butter or lard varies in consistency due to heat and cold.

A still further object of the invention is to provide means for ejecting the contents of the device after a suflicient quantity of material has been provided therein.

Various other objects and advantages of my invention will become apparent during the continuance of the following description.

In the drawings: 2

Figure 1 is a view in longitudinal cross section showing my device as in its preferred embodiment, the plunger being shown in an extended position.

Figure 2 is a view similar to Figure 1 showing the plunger in its rearmost posi tion.

Figure 3 is a view in transverse cross section taken on line 33 of Figure 1.

Figure 4 is a view in longitudinal cross section taken on line 4& of Figure 1, and

Figure 5 is a view in transverse cross sec tion taken on line 5-5 of Figure'2.

The device of my invention consists generally of a body or container portion 10 of a certain predetermined size, open at its forward end as at 11 and provided with a central opening 12 in its rear end as clearly shown in Figure 1. The body may be constrlllcted of any suitable or desirable materia A handle portion 13 is positioned upon the rear end of the body 10 as at 14 and is provided with a longitudinal recess 15 open to the opening 12 of the body portion. Near its rear end the'walls of the recess 15 are constricted as at, 16 and finally terminate in a recess 17 of much smaller diameter than the recess 15 and slightly smaller in diameter than the opening 12 of the body portion. The handle may also be' constructed of any suitable or desirable material.

I also provide a plunger head 18 which operates within the body portion 10 and which is provided with guide lugs 19 which seat and operate in the longitudinal guide ways 20. Upon reference to Figure 2 it will be noticed that the guide ways terminate short of the open end of the body portion so as to limit the forward movement of the plunger head and prevent the same being forced through the open end of the body portion as might otherwise happen.

A plunger rod 21 carries the head 18 and extends through the opening 12 into the recess 15 of the handle 13. hen the plunger head 18 reaches its rearmost position as shown in Figure 2the rear end of the plunger rod will have been guidedinto the recess 17 and thus it will be firmly held against lateral movement. An expansion spring 22 is positioned about the rod 21 one end bearing against the head 18 and the other end against the rear end of the body portion 10. This spring is of sufficient strength to force the head 18 to its forward position and dislodge the material in the body portion. When the plunger 18 reaches its rearmost position the spring is compressed as clearly shown in Figure 2.

h y por o 1 is further provided,

near its rear end, with a longitudinal slot 23 through which projects a standard 24: that is carried on a plate 25. The plate 25 lies outside the body portion 10 between the outer face of the body portion and a guide member 26. A pawl 27 is pivoted on the standard 24 as at 28 and is held in position by means of a tension spring 29 that is carried upon the plate 25. The plate 25 is also provided with an upstanding guide lug 30 that projects through the slot 23 of the I body portion'and lies adjacent thefree end of the pawl 27. In order to regulate the standard 24 so as to vary the capacity of the body 10 Iprovide an adjusting screw 31 which operates through a bushing 32 in the rear end of the body 10 and which is loosely connected to the standard 24 as at 33. Consequently upon manipulation of the adjusting screw the standard2t and the plate 25 maybe moved forwardly or rearwardly with respect to the'body portion 10. y

In order to operate the pawl 27 I equip the handle 13 with an adjustable yoke 34 upon which is pivoted asat 35, an operating lever 36. The operating leverjhas one end connected with apawl 27 by means of a cable or other connecting means 37 whereby upon actuation of the lever 36 the pawl will be moved against the tension of the spring 29. Means such as shown at 38 may be provided so that the yoke 34 can be held in certain adjusted positions on the handle 13 in accordance with the adjustment of the standard 24- and the plate 25.

A fixed pawl 39 is carried on the plunger head 18 in alinement with the pawl 27 above referred to. Consequently when the plunger 18 is moved to its rearmost position as shown in Figure 2 the pawls 27 and 39 will be interlocked thus retaining the plun- V ger in a fixed position until the pawl 27 is released by means of the operating lever 36.

In operation the body portion 10 is thrust into the tube or keg of'material. The material entering the body portion will force the plunger 18 rearwardly until the pawls 27 and 39'will become engaged. The device is then withdrawn, the operator simply presses the lever 36 and the material within the body portion is ejected by action of the spring 22 forcing the plunger outwardly.

WVhat is claimed is:
