6 Claims. (Cl. 73--425.2)
This invention relates to coring devices and, more particularly, to coring devices that may be used to remove samples from baled goods and the like.
Various types of sampling and coring devices have, heretofore, been used 'for removing samples from baled goods such as wool, and the like. However, many of these devices require the use of an external source of power for their operation. This requirement not only reduces the portability of the unit, but also increases the cost thereof.
An object of this invention, therefore, is to provide coring apparatus that is simple in construction, efficient in operation, and which will obviate the need for motor driven operation.
Another object of this invention, is to provide manually-operated coring apparatus that may be easily controlled in use so as to obtain samples of desired quantity with a minimum of effort.
A further object of this invention, is to provide simplified coring apparatus that may be efiiciently used in obtaining samples of baled material, in which the device is manually operated by an operator, requires no outside source of power, and which may be readily disassembled to remove the core sample.
Still another object of this invention is to provide a coring device having no movable parts that may be effec tively used by an operator to obtain samples of baled goods, and which may be manufactured at a reasonable cost.
All of the foregoing and still further objects and advantages of this invention will become apparent from a study of the following specification, taken in connection with the accompanying drawing, wherein:
Fig. l is a front elevational view, partly in section, with parts broken away, showing a coring device made in accordance with this invention;
Fig. 2 is an exploded and enlarged cross-sectional view of certain portions of the device shown in Figure 1, show ing the manner of engagement thereof; and
Fig. 3 is a view similar to Fig. 2, taken along line 3-3 of Fig. 1.
Referring now to Figure l of the drawing, a device made in accordance with this invention is shown to include a canister that includes a circular cylindrical side wall 12 which defines a main body portion at the interior thereof. The lower end of the canister is closed by an end wall 14 that is secured thereto, such as by bolts 15. The upper or opposite end of the canister has a removable closure member 17 associated therewith which includes a thin peripheral flange 18 that is adapted to overlie the exposed upper end 19 of the cylindrical side wall 12.
A pair of toggle-type blocks 21 are carried at diametrically opposite sides of the main body portion and include pivotally mounted hasps 22 that may be placed in releasable engagement with associated keepers 23 carried by the top surface of the closure 17, so as to removably maintain the closure in locked engagement with the upper end of the canister. As more clearly shown in Figure 3, the under surface of the peripheral flange 18 is provided with at least one positioning pin 25 that is adapted to be removably received within a similarly shaped recess 24 in the upper edge 19 of the cylindrical side wall 12 so as to properly position the closure 17 relative thereto. A vertically disposed extension rod 26 is removably received at one end within a threaded opening 27 disposed at the center of the closure member 17. The upper end of the extension rod 26 is provided with a terminal portion 29 of reduced diameter that is adapted to be removably received within a centrally disposed opening 35 in the shoulder or breast plate 36. This opening 35 is provided with a recess or groove 37 that is adapted to receive a ball detent 33 that is biased into engagement therewith by a small compression spring 32 disposed within a transverse bore 30 in the upper end of the extension rod. This ball detent and recess 37 provide satisfactory means for removably maintaining the breast plate and extension rod in an assembled position while providing for relative rotation therebetween. A resilient pad 39 is secured to the upper end of the breast plate 36 so as to provide a cushion for the operator of the device.
Referring again to Figure 1, it will be seen that the lower integral end wall 14 is provided with a centrally disposed opening 41 that is in communication with the bore 42 in a circular bearing block 44 that is rigidly secured to the end Wall, such as by screws 45. These bores 41, 42, are also in communication with the longitudinally extending bore 46 of a tapered coring tube 48 that is threadingly secured at its upper end to the outer end of the circular block 44. The coring tube, at its lower end, is provided with a series of cutting teeth 50 that are adapted to be thrust into cutting engagement with the material that is to be sampled. A pair of operating handles 52 are rigidly secured to the periphery of the circular block 44 such as by attachment screws 53 that are in threaded engagement with threaded openings 54 disposed at diametrically opposite sides of the bearing block.
In actual use, the resilient pad 39 of the shoulder or breast plate 36 is placed into engagement with the shoulder crotch or breast of the operator who grasps both handles 52 with both hands. The cutting teeth 50 of the coring tube 48 are thrust into engagement with the material, such as baled wool, whereupon the handles are used to rotate the canister 10 about its longitudinal axis in a reciprocating manner. By continuously moving the handles 52 back and forth about the longitudinal axis of the canister, while exerting a constant pressure on the breast plate 36, the coring tube is adapted to be moved towards the center of the material being sampled. During this movement, a limited quantity of material is received within and carried upwardly through the bore 46 of the coring tube and into the compartment of the canister. After a sample of the material has been gathered, the device is withdrawn from the mass and the removable closure member 17 released from its securing engagement with the upper end of the cylindrical side wall 12. This provides access to the interior of the canister, whereby the sample of material may be removed. By replacing the the closure 17 and again fastening the toggle lock 21, the device is ready for the next sampling operation.
It should be understood that the coring tube shown is merely illustrative. Accordingly, the coring tube may be of any suitable or convenient size, either tapered or non-tapered; and the cutting edge thereof may be integral therewith or of replaceable type.
Patented Jan. 28, 1958 While this invention has been described with partieular reference to the specific form shown in the drawing, it is to be understood that such is not to be construed as imparting limitations upon the invention, which is best defined by the'claims appended hereto.
