This invez~ti~ is in the field of equipment far handling logs and in particalax chain conveyors for raising logs from one locations to another, such as from a float pond up and onto a conveyor.
BACT~GROUND
In pulp rniIls and like log handli~tg facitlitie$ it is often reduired to transfer logs floating in a pond onto a conveyor fc~r transfer to another location. Chaixt conveyors are coznzx~anly used to accomplish this task. The chain conveyor typically comprises a pair of spaced apart . r conveyor chains with conveyor slats attached perpendicularly across the conveyor chains at regular intervals and extending out from the conveyer ahauns. The lower end of the chain conveyor is below the surface of the pond, and the chain canvc;yar slopes upward to the n uypcr end located just above a belt conveyor oriented substantially perpendicular to the chain conveyer. ,As the slats move out of the water a 1vg is pickod up such that the log lie~r; alarig the slat. The log is carried up to the tap end where it drops onto a conveyor belt, and is carried away. -A problem with these chain conveyors is that the slats are often damaged and must be replaced. Typically the slats arc angle irons oriented with the legs against the chain and the apex above the chain. In this orientation Ivgs rest aganz~t a leg of the angle iron and are carried up the conveyor.
-page2-F
The edges of the legs do not provide suf~.cicnt surface area to weld iza order to provide a weld that will withstand the stresses encountered by the slat when operating. To provide the required welding surface, an insert is welded into the hollow V of the angle iron at locations corresponding to the sidebars of a single link on each conveyor chain. The battonn edge of each insert corresponds to the top edge of each selected sidebar, az~d the edges are welded togethez~ to secure the slat. Typically the slats extend well past the conveyor chair) on each side, requiring the welder installing the slat to weld under the angle iron on each side, necessitating welding at poor angles and with limited visibility_ To replace a slat the original weld must be cut between each insert and sidebar, again with difficult access, the link must be ground smooth to fxt the new insert, and the welding process completed. A typical labor z~eguirement is over two man.-hours to remove and replace such a slat. Often if a single slat is broken, it is just cut offend the chain conveyor runs at reduced capacity until the apparatus can be shut down and repaired_ It is possible for the capacity of a mill to be limited by the capacity of such a chain conveyor, and so the capacity of the mill can be reduced. Shutting down the chain cozzveyar can, mean shutting down the whole mill while repairs take place_ _C
~u><JMMAI~'!~ OLF TAE INVENTION
It is an object of the gz~e$ent invention to provide a log raising chain conveyor apparatus -whcrcin the slats can be changed more quickly and economically that is possible in presently available chain conveyors.
The invention. provides a slat adapter that is welded lc a link of the conveyor chain. The slat is then attached to the slat adapter with a pin, bolt or the like. Thus the slat can be quickly f.
removed and replaced by cutting vff ttxe pin and replacing it with a new slat and pin. If desired the slat could also be welded to the adapter at a convenient and accessible location where it cauId be readily cut and re-welded. The slat adapter is shaped to maintain tlzc proper orientation of tl~e slat with respect to the conveyox chain.

Fi,g.1 illustrates a conventional chain conveyor 1 of the type commonly used to transfer logs 3 floating xn a pond 5 onto a transfer conveyor 7 far transfer to another location. The chain conveyor 1 comprises a pair ofi spaced apart ooz~veyor chains 10 with conveyor slats 11 attached perpez~di cularly across the conveyor chains l 0 at regular intervals and extending out past the conveyor chains 10. xhe lower end of the chain conveyor x is below the surface of floe pond 5, arid the chaizt conveyor 1 slops upward to the upper end located just above the hansfer conveyor 7 that is oriented substantial 1y perpendicular to the chain conveyor l . ,As the slats 11 move out of the pond 5 a log 3 is picked up such that the log lies along the slat -i 1. The log ~ i5 carried up to tie top end where it drops onto the transfer c4nveyor 7, and is carried away to another location for processing or the life.
Commonly the slats ~ 1 are angle irons 12 oriented as illustrated in Fig. 2.
The conventional attachment of the angle iron 12 is illustrated iz~ k'ig. 2. An insert plate 14 is welded between - ~fl~3,e Jr -F
the legs 13 of the angle iron 12 at locations that align with tlxe s~ideb~s 17 of the conveyor chains 10. The sidebars 17 can be afthc offset type, as illustrated in Fig. 7, or straight as illustrated in Fig. 5_ loth of the types can be used in such chain conveyors and the insert plate 14 is fornned to conform to the sidebaz~ 17, whatever its s~e_ Typically the slats 11 are zxaade up with the inset plates 14 welded in place and then delivered to the chain cozaveyar 1 far attachment by a welder. As illustrated in Fig. 3 the slats 11 G
extend past the conveyor chains l a on each side making it dafftot~lt to pr4perly weld the bottom edge 14A of the insert plate 14 to the top edge 17A of the sidebar 17.
Fig. 4 - 7 illustrate attachzx~,ent of the slats 11 in one embodiment of the present ~vention.
A slat adapter 20 comprises a short length of adapter angle iron Z2 has adapter insert plates 24 welded in locations that are aligned with the sidebars 17 ofthe conveyor chain 10, similar to those in the conventional slat attachment of Fig. 2. The adapter angle iron 22 extends only a short distance on either side of the cønveyor chain 10, allowing easy access to securely weld the bottom edge Z4A of the adapter insert plates 24 to the top edge 17A
of the sidebars I ?. The slat adapter 20 includes a bolt hole 2G from one side to the other as illustrated. '> he iilastaated bait holes 2G on each side of the adapter angle iron 22 are jointed by a pipe 28 to facilitate ca,sy insertion oftha Molt 30. Corresponding slat holes 32 in the angle iron 12 align with the bolt hales 26, such that the bolt ~0 can be pushed through the aligned halt and slat holes ~.6, ~2 when the slat 11 is put in position on the slat adapters welded to the conveyor chains 10 an each side of the ck~ain conveyor 1, as illustrated in Fig. 4. -Thus in order to replace a slat 11, it is only required t4 remove the bolts 3 0 on each side by removing or cuttiz~~; off the nut 34. 'The new slat is put itt position and a new bolt secures same to the slat adapters 20, In a matter of minutes the slat 11 can be replaced.
Fig. 8 and $ illustrate an alternate embodiment of a slat adapter 120. The adapter angle iron 122 and insertplates 124 are made the same as is the prior embodixnent of figs. 4 - 7 and the ..
slat adapter 120 is attached by welding to the sidebar 17 in the same manner.
In this ezxxbodim~ent the attachtncnt of the slat 111 is by a pin 130 extending up from the apex of the adapter ar:gle iron 122 through a eorrespondin,~ hale 132 in the apex ofthe angle iron 112 of the slat 111. A roll pen 135 is shown through a bolt 137 in the pin 130 to secure the slat 1 I 1 to the slat adapter 120, and thus to the conveyor chain 10. A, threaded gin and bolt, or other conventional fastener could also be used.
1~ig,10 illustrates another alternate embodiment of a slat adapter 220. The adapter angle iron 222 is truncated. The insert plates 22~ are made the same as in the prior embodiments and the slat adapter 22a is attached by welding to the sidebar 17 in the same manner. In this etnbacltment the attachment of the slat 211 is by bolts 230 extending up from each end ofthe adapter aaxgte iron 222 through corresponding holes 232 in each leg 213 of the at~.fe iron 212 of the slat 211. A nut 23~ is threaded onto each bolt 230 tc secure the slat 211 to the slat adapter 220.
In the above embodiments the legs 13 Qf the slat 11 are secured to corresponding legs ofan n adapter angle iron 22 such that the proper orientation of the slat 11 is maintained during operation. Alternatively Fig. 11 illustrates an embodiment where the slat 311 is maintained in the proper orientation by flanges, illustrated as rods 322, that bear against edges ofthe slat ., legs 13. The slat 311 is attached by a bolt 330 through the slat 311 and threaded into a nut -attached to the slat adapter 320_ In all embodiments the slat adapters 20 can be readily welded to the sidebars 17, and lefk iv place when it is reduired to change a slat. repairs or replacezz~.ont of the slat adapters 24 can be readily accomplished as they are fully exposed when the slat 11 is removed.
