SAMPLER. I

Application filed May is, 1913. Serial No. 767,247;

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, FRANK H. PEQK, of J amesville, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Samplers, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improvements in samplers and pertains more particularly to a device for sampling cement, grain or other loose material adapted to be deposited or confined in bins or retaining receptacles of some depth. 7

It is well known among those familiar with the manufacture, storing and handling of cement, grains, etc., that it is very diflicult to determine the condition or quality of the material at various depths, or to obtain samples of the material for inspection or examination by prospective purchasers.

The primary object, therefore, of this invention is to produce a simple and efficientdevice which may be used for obtaining samples of loose materials of various kinds, at any desired depth of the material and which may be constructed with a minimum of expense and material.

Devices of this kind have been constructed of two telescoping tubes or sleeves having openings adapted to register in a predetermined position andone rotatable within the other for moving the openings in the re spective tubes out of registration with each other. In this class of devices, however, it is impossible when buried ina mass of material, to determine the exact position of registration of the openings or the exact position when the openings are out of registration and the chamber closed, and unless the chamber is tightly closed when the device is withdrawn with its sample of mate rial, the utility is destroyed for the reason that grain or cement from diflerent stratas will fall into the chamber and mingle with the sample.

A further object, therefore, of my invention is to provide means for positively closing said chamber, operable in such a manner that the operator will know that the chamber is closed although it is out of sight, by providing upon the inner or telescoping sleeve a projecting flange adapted to engage the outer sleeve when the chamber is closed.

In the drawings-Figure 1 is a front view of my sampler. I Fig. 2 is a cross section on line 2-2, Fig. 1. Fig. 3 is a cross section Patented Sept. 9, 1913.

on line 33, Fig. 1; Fig. .4 is a cross see tion, similar to that shown in Fig. 3 except the opening into the cliamber'is shown as closed. Fig. 5 is a perspective view of the inner or telescoping sleeve. i

The device comprises a cylindrical tube 1- preferably formed of sheet metal, having hollow frusto-conical sections and 3, preferablyformed of sheet metal, attached to its respective ends, in any suitable manner as soldering, and adapt ed to form with the tube l an elliptical chamber. The outer end of the frustoconical section 2 is somewhat elongated and externally threaded for receiving an extension bar 4:' having a hollow-internally threaded end 5. For preventing relative rotation of these parts when in the desired position, I have provided a set screw 6- adapted to bear against the threaded portion of the section 2-. In

like manner the outer end of the section 3 is somewhat elongated and externally threaded for receiving a point or spear 7-' having an internally threaded portion, and in like manner I have provided the spear 7 with a set screw --8- adapted to bear against the threaded portion of the section 3 for preventing relative rotation of these parts. I

The tube 1 is provided with an open ing 9, preferablyrectangular in shape and vertically arranged with respect to the tube, as shown, and with an inner telescoping cylindrical member or sleeve 10-, preferably formed of sheet metal, and of substantially equal extent with the tube l, and having an opening -11 of sub stantially the same size as the opening 9 .in the tube 1 and preferably formed by cutting away a portionof the sleeve upon three of its sides and bending it back along the remaining attached side to form a projecting flange 12- and this flange 12-' is adapted to lie in and project from the opening 9 in the tube 1-, the extent of this projection -12, depending largely upon the consistency and weightof the material in which it is designed to operate, and

it will be apparent that this projection may be formed in the manner above described of almost any extent without affecting the operablene'ss of the.,device, for the reason that the portion ofthe sleevelO- which closes the opening %9. lies behind the flange and i r the extent of the openin in the sleevewill not in anyway a ect, the size of the opening -9 unless the flange 12 be of less'extent than the Width of the opening 9-.

' taehed thereto in any suitable manner.

When the device is insertedlin a mass of cemenhgrain or other loose material, the spear or point 'Z' makes a passageway for the rest of the device, Which is, of course, inserted with the chamber in closed position, as shown in Fig. 4. When the desired depth is attained, the handle l3 is turned, whereby the outer tube l.'is roe tated. The flange l2 on the sleeve V-'-1.O-'. frictionally engages the cement, grain or other material and prevents rotation of the sleeve so that rotating the handle --l3 counter-clockwise, in Fig. 1, causes the openings -9 and 1l to register and material may enter the chamber formed by the sections 1, 2 and 3, respectively. The flange -rl2 not only prevents rotation cf the sleeve 10 but also engages the edge of the tube 1 surrounding opening -9 and prevents further rotation of the sleeve 10. the opposite direction, the tube 1- is turned back again, the sleeve 10 being stationary until the other edge of the open ing -9+ engages the flange ,10 and the opening .9 is closed. Further rotation By turning the handle 13 inv of the handle -13 tends to close the opening more tightly.

' The device may then be withdrawn from the material and will contain a true sample from the depth desired. It is readily apparent that the section 3- may terminate in a point and that the spear or point -.7 may be omitted without departing from the spirit of my invention, as set forth in the appended claim. t is u her appa ent ha he l e 10 need not be cylindrical or circular in cross section,but may be any are of a circle of sulticient extent so that the portion upon either s de c he an e the on i y ex e d 'in Wi th, e dth. of the Op nin in the outer sleeve, s A I What I claim is; a

In a sampler, snbstantially cylindrical sleeve having an opening throngh' a Wall h re a fla ge Pr je ting m he leev adjacent said opening, an outer section inclosing said sleeve tern ing a chamber extending above and below the same and having an opening through a all thereof and through which the flange upon the sleeve is adapted to extend, said onter sec? t es h g a Point a it 9 e nd means in connection with said section ada ted to extend above t e material to be sanip ed for rotating said section.

In witness. whereof I have hereunto set my h nd hi 7 t y Of May FRA K H- ECK- YVitnesses:
