Drill core trays and accessories for use therewith

Abstract

A drill core tray ( 100 ) comprises a sheet metal base plate ( 104 ) shaped to form a number of elongated recesses ( 114 ). The recesses ( 114 ) are separated by dividers ( 112 ) comprising inclined lower sides ( 120 ) leading into upstanding side Walls ( 122 ) which join to form an apex ( 124 ) which is located above the horizontal diameter of a core received in the recess. A core lifter ( 200 ) is used with the tray ( 100 ). It has arms ( 204 ) constituting a hemi-cylindrical body and terminating in an open mouth ( 208 ) opposite which is a channel ( 210 ). The lifter ( 200 ) includes a pair of handles ( 214 ). The mouth ( 208 ) can pass over a core ( 102 ) in a recess ( 114 ) and by rotating the lifter ( 200 ) the arms ( 204 ) pass under the core ( 102 ). On further rotation, the channel ( 210 ) engages an apex ( 124 ) about which the lifter ( 200 ) can pivot to lift the core ( 102 ) out of the tray ( 100 ).

1 . A drill core tray comprising a sheet metal base plate shaped to provide a number of elongated recesses into each of which a core may be received fitting closely therein and each of which, in section, comprises a base and inclined lower sides leading from the edges of the base wherein the lower sides continue into upstanding side walls with the upstanding side walls of adjacent recesses converging slightly to form a divider having an apex which is located above the horizontal diameter but below the upper portion of a core received in the recess. 
   
   
       2 . A drill core tray as claimed in  claim 1 , wherein the ends of the tray are closed by end walls. 
   
   
       3 . A drill core tray as claimed in  claim 2 , wherein side and end stop surfaces are provided at and outside the corners of the end walls to define a space within which an identical tray can be received to be stacked on the lower tray. 
   
   
       4 . A drill core tray as claimed in  claim 1 , wherein a pair of horizontal slots are provided in the end walls and wherein flat fabric handles are provided outside the end walls, each handle having end parts that respectively pass through the slots to attach the handle to the end wall. 
   
   
       5 . A drill core tray as claimed in  claim 4 , wherein stop means are provided at the end parts of each handle. 
   
   
       6 . A drill core tray as claimed in  claim 5 , wherein the stop means each comprise a bent over section of the end parts of the handle that form upwardly open “U”-shaped portions which can engage the material of the side walls when lifted, the thickness of the slots being such that the “U”-shaped portions can pass therethrough to attach the handle to the core tray. 
   
   
       7 . An accessory for use with a drill core tray comprising an elongated sheet metal member bent to form arms constituting a hemi-cylindrical body terminating in an open mouth with extensions to the ends of the arms which extend parallel and approximately tangentially to the parts of the body to which they are connected and further comprising handle means on the accessory to facilitate holding the accessory, wherein the accessory can pass over a core in the core tray and then be rotated about the axis of the body to lift the core out of its recess. 
   
   
       8 . An accessory as claimed in  claim 7 , wherein the member has a length of about the same length as the recesses in the drill core tray. 
   
   
       9 . An accessory as claimed in  claim 7 , having a protruding channel formed therein directly opposite to the mouth. 
   
   
       10 . An accessory as claimed in  claim 7 , adapted for use with a drill core tray, comprising a sheet metal base plate shaped to provide a number of elongated recesses into each of which a core may be received fitting closely therein and each of which, in section, comprises a base and inclined lower sides leading from the edges of the base wherein the lower sides continue into upstanding side walls with the upstanding side walls of adjacent recesses converging slightly to form a divider having an apex which is located above the horizontal diameter but below the upper portion of a core received in the recess, the accessory having a protruding channel formed therein directly opposite to the mouth, wherein when the body has engaged a core and has been rotated relative thereto, the channel will engage the apex of a divider to lift a core received in the body out of a recess. 
   
   
       11 . An accessory as claimed in  claim 7 , wherein the handle means projects from the side of the body. 
   
   
       12 . An accessory as claimed in  claim 11 , wherein the handle means comprises two spaced handles. 
   
   
       13 . The combination of a drill core tray with an accessory for use therewith,
 the drill core tray comprising:   a sheet metal base plate shaped to provide a number of elongated recesses into each of which a core may be received fitting closely therein, and each of which, in section, comprises a base with inclined lower sides leading from its edges wherein the lower sides continue into upstanding side walls with the side walls of adjacent recesses converging slightly to form a divider having an apex which is located above the horizontal diameter but below the upper portion of a core received in the recess, and   the accessory comprising:   an elongated sheet metal member bent to form arms constituting a hemi-cylindrical body terminating in an open mouth with extensions to the ends of the arms that extend parallel and approximately tangentially to the parts of the body to which they are connected and being spaced apart so as to be able to receive a core therein and being able to fit between the side walls, and   handle means on the accessory to facilitate holding the accessory, wherein the arms of the accessory can pass over a core in the core tray and within the recesses in which the core is received and then can be rotated about the axis of the body to lift the drill core out of its recess.
