WILBUR DENIO KISTLER,

OF SHERIDAN, WYOMING.

SAMPLE lt'iACI-IINE.

Application filed February 17, 2923.

T at whom it may concern:

Be it known that VVrtnru: D. KIs'rLnn,

a citizen of the United States, and resident of the city of Sheridan, county of Sheridan, State of Wyoming, whose post-oflice address is Sheridan, l Vyoming, has invented certain new and useful Improvements in Sample Machines, of which the following is a specification.

The fundamental purpose of the present invention is to provide simple, efiicient and comparatively inexpensive sample extracting means designed principally for use in connection with apparatus for the milling or treating of flour but which is capable of being used with equal facility in connection with the manufacture or treatment of other materials wherein it is necessary or desirable that samples of the material be periodically extracted for the purpose of inspection.

The foregoing and other important purposes and advantages of the invention will be more readily appreciated by reference to J) the following detailed description and accompanying drawings wherein I have disclosed a preferred embodiment.

In the drawings,

Figure 1 is a view partly in vertical sec-- -"l tion and partly in side elevation of my invention as it will appear in actual use.

Figure 2 is a top plan view of the construction disclosed in Figure 1, and

Figure 3 is a view similar to Figure 2 but showing certain parts in a different position.

Referring more particularly to these drawings, numeral 1 may be taken to represent a. spout, conduit, or container to which the flour or other material is delivered during the process of manufacture or treatment thereof. As herein disclosed, the member 1 more closely resembles a conduit and, for the sake of convenience, is so termed in the following description.

At a suitable point in its length the said conduit 1 is provided with a side opening 2. the effective area of which is variable through the medium of a sliding gate 3 movable in a suitable gateway 1 and adapted to be secured in various adjusted positions through the inst-rumentality of a. set screw 5.

A sample extractor, designated by the nu meral 6, is movable inwardly and outwardly through the opening 2 and as herein disclosed consists simply of a flat plate of suitable Serial No. 619,743.

width and length supported to move in a straight iine by means of suitable guidesT secured to the upper end of a sample box 8. The sample box 8 is preferably secured to one side of the conduit 1 with the upper end of the box terminating flush with or in the plane of the lower edge of the opening 2 so that the aligned edges of the box and open ing serve as a further support for the extracting member 6, in certain positions of the latter.

The outer end of the extracting member 6 is secured to one end of a. connecting rod 9 having its opposite end fastened to the crank 10 of a crank shaft 11. The shaft 11 is mounted in

suitable bearings

12 and 13 carried by a supporting structure 14. At one end, the said shaft 11 is equipped with a belt pulley 15 adapted to be connected with the driving mechanism of the apparatus for manufacturing or treating the material delivered to the conduit 1 so that the sample extractor 6 will be in constant operation during the process of mainifacturing or treating said material.

In the use of the device the extracting member 6 is periodically moved inwardly and outwardly through the opening 2 by means of its connection to the crank shaft 11. On the outward movement of the extracting member, the sample deposit accumulated thereon is engaged by a. suitable brush 16, which serves to sweep said material into the sample box 8 and this brush is preferably supported by a. bracket member 17 extending outwardly from the conduit 1. The amount of sample material to be extracted from the conduit may be easily regulated by increasing the width of the extracting member 6 or by changing the position of the sliding gate 3 to increase or decrease the effective area of the opening 2, the lower edge of said gate acting as a Scrapper to remove excess material from the extracting member as shown to advantage in Figure 1.

lVhile I have described in the foregoing what I now consider to be the preferred embodiment of my invention, it is to be understood that various changes in the proportion and arrangement of parts may be resorted to within the scope and spirit of the appended claims.

I claim:

1. The combination of a conduit having a side wall provided with an opening and gateway formed between the inner and outer sides of said vWall andcommunicat-' ing With said opening, agate slidable in said gateway and adapted to pro eet into said opening to vary the effective area of" 2. The combination of a conduit having a vside wall provided with an openmg'and a gateway formed between the inner and out er sides of said Walland positioned above the opening 1n communication therewith, a sample receptacle secured QXtGllOllY to said arranged to travelinwardly and outwardly through said openingand sii'pported for sliding movement on the upper end of said receptacle, guide means carried by the re ceptaole andengaging said slide, a brush secured exteriorly to the said side 'Wall of the conduit and arranged toengage the per surface of the slide and means for tuati ng the slide. r Y r In testimony whereof l hereunto ai'fix signature,

WIL R :onni'o KISTLER.
