Abstract

"SAFETY CLUTCH AND QUICK RELEASE ASSEMBLY FOR GRAIN AUGERS
AND THE LIKE"
ABSTRACT OF THE DISCLOSURE

In my patent no: 9745919, a slip clutch assembly is shown which enables the intake end of the auger flight to stop rotating if equipment or a limb of the operator in-advertently engages the intake end. The present device in-cludes an actuating lever adjacent the intake end so that the intake end portion of the auger can be disengaged from the main auger flight if desired. A remote actuating lever is situated adjacent the discharge end of the auger tube operatively connected to the actuating lever adjacent the intake end so that remote control is possible. Over center linkage is provided so that the slip clutch assembly is either held in the engaged or disengaged position depend-ing upon the position of the actuating lever.

"SAFETY CLUTCH ANl) QUICK RELEASE ASSE~IBLY FOR GRAIN ATJGERS
AND THE LILYE"
BAC-~GR~UND OF THE INVENTION
This invention relates to new and useful improvements in safety clutch and quick release assemblies for grain augers and tne like.
In my patent no: 974,919~ I disclosed structure in which the intake end of trle auger flig'nting is connect-ed to the main auger flighting by means of a slip clutch so that if an obstruction is engaged within the intake end auger portion, this portion stops thereby preventing damage either to the obstruction, or to the auger assembly. Al-tnough grain auger intake ends are shielded nevertheless when being used under certain circumstances~ the shielding interferes with the pick up of grain or other comminuted material so t'nat the shield is often removed from t'ne intake end. It will be appreciated that this will present a danger not only to personnel working near the intake end but also to the auger structure if an obstruction engages within the intake end such as a length of lumber or the like.
The present invention overcornes disadvantages of the structure shown in Canadian Patent 974,919, said dis-advantages including lack of control by the operator if it is desired to stop the intake end of the auger assembly from rotating. It may be desirable to s-top -the intake end for example to empty tne auger before removing tne auger frorn the grain bin. Furthermore if t'ne auger becomes over-~ 37~

loaded, the intake end cannot be stoped in patent 97h,919until the overload ls cleared.
SUt~ARY OF THE INVENTIOI~
_ ~ . .
T'nis invention overcomes these disadvantages and in accordance with the invention there is provided, in an auger assembly which includes an auger tube, an auger flight on a main auger s7naft journalled for rotation there in and having an intalce end and a discharge end; a sa$e~y clutc'n and quick release assembly for said intake end compris-ing in combination an intake end auger shaft portion extend-in~ from and rotatable with the main auger shaft, means to support the distal end of saidintake end auger shaft por-tion, an intake flignting component, a tubular shaft por-tion around which said flighting component is mounted and secured, said tubular shaft portion being mounted for free rotation upon said intake end shaft portion, a clutc'n as-sernbly selectively and operatively connectable between said tubular shaft portion and said intake end shaft portion and means to selectively end shift said tubular shaft portion relative to sai.d intake end shaft portion from a clutch engaging position to a clutcn disengaging position and vice versa.
Another aspect of the invention provides an auger assembly comprising in combination an auger tube, an auger flight on a main auger s'.~aft and journalled for rotation tnerein and having an intake end and a aiscnarge end, a 3i~

safety clutch and quicl~ release assembly for said intake end, an intake end auger shaft portion extending from and rotatable with tne main auger shaft, means to support tne distal end of said intake end auger shaft portion, an in-take flighting component~ a tubular shaft portion around which said fli.~hting component is mounted and seeured, said tubular shaft portion bein~ mounted for free rotation upon said intake end shaft portion, a clutch assembly se-leetively and operatively connectable between said tubular : 10 shaft portion and said intake end shaft portion and means to selectively end shift said tubular snaft portion relative to said intake end snaft portion from a elutch engaging position to a elutch disengaging position and viee versa.
A furt~er aspeet of the invention is to provide a devi.ee of the eharacter herewithin described which is readily fitted to existing auger intake ends.
A yet furtner advantage of the invention is to provide a device or the character herewithin described which is simple in construction, econornical in manufaeture and otherwise well suited to tne purpose for which it is designed.

DETAILED DESCRIPTION

.
Proceeding therefore to describe the invention in detail, re-ference character 10 illustrates an auger assem-bly which includes an elongated auger tube 11 having a main shaft 12 therein around which is provided an auger flight 13 all of which is conventional.
Reference cnaracter 1~ illustrates the intake end of the auger assembly which of course is open and guard bars 15 extend longitudinally from the intake end of the auger tubing and are secured to a spider or end plate 16 by means of bolts 17. Tnese act not only as partial guards to the 3 7 ~t intake end but also support the intake end so that auger -Elighting does not engage the supporting surface.
The safety clutcn and ~uick release assembly is si.tuated within the intake end and is designated generally by reference cnaracter 18. It consists of an intake end au~er shaft portion 19 the inner end 20 of which engages the lower end 21 of the main auger snaft 12 which is usually tubular and hollow. Tinis intake end auger shaft portion 19 may be secured wl.thin t'ne end 21 either by an adhesive such as "Lock Tight" (Registered Trade L~ark) or by any other con-ventional means such as set screws or the like.
The lower end 22 of this shaft portion 19 is center-ed and supported by means of a bearing assembly 23 situated centrally of the spider or end plate 16 and a collar 24 en-gages around this e~ternal end 22 and is secured by means of set screws 25 or the like as clearly shown in ~igure 2.
An intake flighting component is provided collec-tively designated 26. It includes a tubular shaft portion 27 having an intake flig'nt 28 secured thereto and being similar in diameter and configuration to the main auger flight 13. ~owever it is p~.ceferable that the outer edge 28 of the intake auger flighting can be rounded or smoothed so that a sharp edge is not presented which could conceivably damage the limb of the operator if engaged tnereby even al-though means are provided to stop t'ne intake auger flighting from rotating if tnis occurs.

~' J6~3'7~

A tnrust bearing 29 mounts the lower or distal end o the tubular shaft portion upon the intake end auger snaft 19 so that the intake fli~hting component 18 is free to ro-tate -upon t'ne s'naft portion 19.
Means are provided to selectivel.y connect the in-take flig'nting componerlt to tlne main auger shaft 12 so that the intake fligntir~component can selectively rotate with the main auger shaft 12 or can be stationary relative thereto. Said m,eans takes t'ne form of a cone clutch as-sembly collectively designated 30 and including an outer clutcn element 31 welded or otherwise secured to t'ne intake end auger shaft portion 1~ adjacent the end 21 of the main shaft 20.
An inner cone clutch component 32 is in turn se-cured to the upper end of the tubular shaft portion 27 ad-jacent the outer cl.utch portion 31 as clearly snown in Figure 2.
'l~eans are provided to end shift t'ne intake flight-in~:, c.omponent along the intake end auger snaft portion 19 so that the clutch 30 may engage or disengage with s~ffi-cient force, when engaged, to rotate t'ne intake flignting co~mponent yet at the same time penrlit the intake flighting component to stop if an obstruction is engaged there'r~y.
To this end, there is provided a yoke assembly collectively designate~ 33. This yoike assembly includes side grooves 3~ formed on either side of a collar extension ~ J 1~37,~

35 extending from the thrust bearing 29. A yoke lever 36 is provided witn a bifurcated end 37 and pivoted by this bifur-catea end by pivot pin 38, to a support 39 extending in-wardly from the aforernentioned end plate 16 so that move-ment of the yoke lever 36 in the direction o:E arrow 40, will end s'nift the tubular shaft portion 18 in the direction of arrow 41 thus disengaging the clutcn 30 and permitting the main au~er shaft and fliglnting 12 and 13 to rotate in-dependently of the intake flighting component which of course is then stationary upon the intake end auger shaLt portion ].9.
~ eans are provided to move the yoke and hence the intake flighting component 18, said means taking the form of a rigid link 42 engaged by one end thereof with the dis-tal end 43 of the yoke link 36 and being guided by guide 44 e~tending from adjacent the lower end of the au~er tube 11 .
A turnbuckle assembly 45 forms part of the rigid : link 42 for selectively adjusting the effective length thereof and wing nut 46 locks the turnbuckle in the desir-ed position.
The rear or upper end 47 of t'ne link 42, Otl the tne other side of the turnbuckle 45, pivotally engages with-in a lug 48 extending from a lower or first actuating lever 49 pivoted to the auger tube 11 upon pivot 50 and situated adjacent the intake end of the auger assembly.

t ~ ~37~

The angulation of the link portion 47 and t'ne position oE lug 48, as shown in Figure 1, permits an over center action to the actuating lever 49 upor- movement of an extending handle portion 51 in the direction of arrow 52.
When moved in this ~irection and when the turnDuckle 45 is adjusted correctly, the in-take flighting component 18 is moved endwise in the direction of arrow 41 thus disengaging clutch 30 and maintaining the intake flighting component in this disengaged position.
When the handle 51 is moved in the direction opposite to arrow 52 then tne linkage 42 end shifts tne in-take flighting component in a direction opposite to arrow 41 thus engaging the clutch 30 and causing the inta~e flight-ing component to ro.ate. Once again the over center action rnaintains the clutch 30 in the engaged position and adjust-ment of the linkage will supply sufficient pressure to the clutch to enable the intake flighting component to rotate and move grain into the main auger assembly yet at the same time will allow slippage to occur if an obtstruction enters the intake end 14.
~ eference to Figure 4 will show a further actuat-ing lever 53 pivoted intermediate the ends thereof upon a pivot 54 adjacent tne discharge end 55 of tne auger assem-bly. Cables or linkage extend ~rom the lever 53 one upon either side of the pivot 54 and are operatively connected to the a~orementioned first lever 49 one upon either side of 3 7 ~
_9_ the pivot 50 with adjustab]e turnbuckles 57 being provided ln a conventional manner.
This permits the operator to control tne action of t'ne intake flignting component 18 either from a position adjacent the intake end, by means of handle 51 or from a position adjacent tne discharge end by means of the lever 53.
Tnis means tnat it is possible for the intake flighting component to be stopped in an emergency from either position and it also permits the auger to be emptied prior to removing the auger assembly from t'ne grain bin, truck or the like.
Furt'nermore if trle auger becomes overloaded, the intake can be stopped instantly from eitner position until the overload is cleared. Furthermore the operator on a truck being loaded can stop the auger feed from either position and empty t'ne main auger at the same time.
It will also be appreciated, t'nat in comparison with my previous patent hereinabove mentioned, the intake flighting component can be stopped if an obstruction is en-gaged rather than let the clutch continue slipping.
In order to fit the assembly to existing grain augers, it is only necessary to cut off the conventional in-take end portion of the snaft and flighting and install the present assembly by engaging the end of the intake and auger shaft portion 19 within t'ne hollow end 21 of the main shaft ~ :~ S~37~

~lo--Furthermore if the thrust bearing 29 seizes up.
then the intake flighting component 19 will cease to rotate.
If aesired, a spring (not illustrated) may extend between the end plate 16 and the collar 35 normally urging the clutch 30 in the engaged position but witn the over center arrangement of the control lever or handle 51, normal-ly this is not necessary.
Finally it will be appreciated that the entire assembly can be bolted onto the intake or lower end of the auger casing 11 by means of tne clamp portion 57 and bolts 58 extending from adjacent the inner end of the guard mem-bers 15.
Since various modifications can be made in my invention as nereinabove described, and many apparently widely diEferent embodiments of saMe made within the spirit and scope of the claims without departing from such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illus-trative only and not in a limiting sense.
