LIQUID-SAMPLER.

Specification of Letters Patent.

Patented Mar. 11, 1919.

Application filed May 16, 1918. Serial No. 235,042.

To all whom it may concern:

Be it known that I, CHARLES J. HAGG- STROM, a citizen of the United States, residing at Warren, in the county of Warren and State of'Rennsylvania, have invented certain new and useful Improvements in Liquid-Samplers; and I do declare the follow ing to be a full, clear, and exact description of the invention, such as .will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to liquid samplers, and it relates more particularly to an improved automatically closing sampler.

'One of the objects of this invention is to greatly improve and simplify devices of this character;

A further object is to eliminate springs and other parts that easily break or get out of repair; v

A further object is to provide for preventing the leakage that occurs in consequence of the wearing of the valves or closures employed in other known devices of this character;

Another object is to provide a device of this character which is thoroughly practical and may be manufactured at a comparatively low cost;

Other objects and advantages may become apparent to persons who read the following details of description in connection with the accompanying drawings, in which:

Figure 1 is a side elevation of my improved sampler suspended in a liquid receptacle;

Fig. 2 is a vertical sectional View, the parts being in the tripped and closed position at the bottom of the tank, ready to be withdrawn with its liquid contents;

Fig. 3 is a View similar to Fig. 1, but showing the relatively short latch-shifting rod replaced by a longer latch-shifting rod;

Fig. 4 is an enlarged fragmental sectional view more clearly illustrating the principal working parts of the device.

Fig.- 5 is a detail view: of the lower end of the device, the line of vision being at riggit angles to the line of vision of Fig. 4; an

Fig. 6 is a horizontal sectional view along the line 66 of Fig. 4.

Referring to these drawings in detail, in which similar reference characters correspond with similar parts throughout the several views, a glass tube 7 is supported by a frame which consists of a lower member 8, an upper member 9 and vertical rods 10. Each of the members 8 and 9 is provided with an annular depression or seat in which the ends of the tube 7 are seated on suitable packing elements, and each of these frame members 8 and 9 is provided with a hearing 11 and 12 respectively. The upper and lower ends of the tube are normally open during its descent through 'the liquid to be sampled, so that the liquid within the tube is substantially of the same consistency as the liquid surrounding the tube. The lower end of the tube is provided with a closure seat 13 which is formed on the frame memher 8. One or both of the rods 10 may be provided with a measuring scale, or said measuring scale may be otherwise applied to the tube so as to indicate measurements of the stratas of liquid in the tube.

The tube 7 is supported and moved vertically by means of a normally vertical rod '14, this rod being supported by a rod 15,

through the medium of an arm 16 which is rigid with the rod 14. At the lower end of the rod 14 is fixedly secured a closure or horizontal plate 17 which is provided with a packing disk 18, the latter being adapted to fit snugly against the closure or seat 13 and to cooperate therewith for preventing or allowing egress of the liquid through the lower end of the tube. The tube 7 and rod 14 have longitudinal and rotary movement groove 19 constitutes a helical element which cooperates with a'bOlt or stud for effecting a quarter turn of the rod with relation to the tube 7 during the relative longitudinal movement of these-

elements

7 and 14.

In order that the rod 14 may support the tube 7 and its frame 8910 in the position illustrated in Figs. 1, 3, 4. 5,.and 6, I

' provide a latch 21 having a hook 22 which engages with the lower surface of the frame element 11,-this latch being pivotally mounted at 23 on a collar 26L which is fixed on the rod 14 by means of a set screw 25. The

latch 21 is provided with an eye 26 through.

which a cord or cable may be passed, and if desirable, the hook 22 may be released from the bearing 11 by drawing the eye 26 upward. However, as it is usually desirable that the device be automatic in its operation, I provide a rod or latch-shifting element 27 which is pivotally connected at 28 to the latch 21 and depends therefrom; the

lower end of the rod 27 extending below the lower end of the rod ,14 so as to be in posltion to strike and be arrested by the bottom of the liquid receptacle. The lower end portion of the rod 27 is preferably guided by an opening 29 in the closure 17, the rod 27' being free to reciprocate through the opening 29. A rod 30 is interchangeable with the rod 27 so as to facilitate the automatic taking of samples at difierent levels in the receptacle, each of these .rods being pivotally connected at 28 in the same manner as the rod 27 is connectible, as clearly illustrated in Fig. 3. However, when the rod" 27 is in use, the rod 30 is preferably carried by supporting

elements

31 and 32 of the tube-carrying frames. The lower end of the rod 30 is preferably provided with a screwthreaded connection 33 which prevents its disengagement and loss, and also cooperates with the rods 10 for stiffening the frame.

In operation the device is lowered into a liquidreceptacle, by means of the rod, wire or cord 15, the closure 17 being out of longitudinal alinement with the tube 7, as more ,clearly shown in Fig. 6 so that the liquid en-' by means of'the helical groove 19 and stud 20 until the closure disk-18 is snugly seated against the closure seat 13; and now upon drawmg' the element 15 upward, the valve closure 18' cooperates with the elements 14, i5

ment of my invention very minutely, it is not intended to limit my invention to these exact details of construction and arrangement of parts, but I am entitled ,tdmake changes within the scope of the inventive idea disclosed in the foregoing description and. following claims.

What I claim as my invention is:

1. A liquid sampler comprising a tube, a rod having a helical elementnthereon', a closure element carried by said rod, means supporting said tube and being movable along said rod, and means cooperative with said helical element and with the first said a means so as to eflect the closing of an end of said tube by a rotary movement of said closure element while the tube moves downward'into contact with said closure element.

2. A liquid sampler comprising a tube, a rod having a helical element thereon, a closure element carried by said rod, means supporting said tube and being movable along said rod, means on said rod for detaining the first said means and operable to release the latter and thereby permit its movement along said rod, and means cooperative with said helical elementa-n'd with the first said means so as to effect the closing of an end of said tube by said closure at the termination of said movement.

3. A liquid sampler comprising a rod having' a helical element, means for supporting said rod in a substantially vertical position and for lowering said rod into a liquid receptacle, a tube supported bysaid rod and adapted to have rotary and longitudinal movement relative to the rod, aclosure fixed on said rod, a latch pivotally secured to said rod and being cooperative therewith to hold said tube in spaced relationto said closure and out of longitudinal alinement with the latter, means for moving thelatch and thus allowing said tube to descend by gravity along said rod, and means cooperative with said helical element for causing said rotary and longitudinal movement and thus efi'ecting the closing of one end of the tube by said closure.

4. A liquid sampler comprising a rod having a helical element, means for supporting said rod in a substantially vertical position and for lowering said rod into a liquid receptacle, a tube supported by said rod and adapted to have rotary and longitudinal movement relative to the rod, a closure to hold said tube in spaced relation to said closure and out of longitudinal alinement with the latter, a rod depending from said latch and operable by its contact with the bottom of the receptacle so as to move the latch and thus allow said tube to descend by gravity along the first said rod, and means 10 cooperative with said helical element for causing said rotary and longitudinal movement and thus effecting the closing of one end of said tube by said closure.

In testimony whereof I have hereunto set my hand.

CHARLES J. HAGGSTROM.
