ATTORNEY Patented Feb. 17, 1953 GEARING Aldan J. La Beck and Leland E..Hoy, Clatskanie, Oreg.

Application October '18, 1949,..Seria1.No..122,0.84.

1 Claim. 1 Our invention relates to power pick up -rolls which are particularly adapted to be'mounted to the gunnels of fishing boats for picking up 'gi'lnets.

The primary object of our invention is to provide a fluid driving assembly for revolving the roll of the pick up unit. By using a fluid drive system, line shafting, bearings and the like are eliminated, together with troublesome belting, which is now being used.

A further object of our invention is to provide a drive forthe'pick up roll that will permit shiftingthe'pick up'roll unit from one part of the boat to another, and further provide for ease of control from various locations on the boat.

A further object of operating the roll by fluid drive is that pressure safety valves protect the system and thespeed of, the roll can be varied at will be control valves.

Another feature of our invention is the fact that an over-running clutch is provided within the driving assembly so that in the case where the net is drawn in rapidly the drum will over-run permitting this quick retrieving of the net, but the driven roll will be always ready to assist in pulling the net in when the going gets harder in the pulling in of the net.

Another feature of our invention is the fact that it is self-lubricating, the driving parts running'ina bath of oil.

And a further object 'of' the invention is the fact that any number of pick up units can be operated from the same system "of power.

These and other incidental objects willhe. apparent in the drawings, specification and. claim.

Referring. to the drawings:

Figure 7 is a longitudinal sectional view of the pick up drum unit, taken on line 1-'| of Figure 1,

parts of the gunnel of the boati-bro'ken awayfor convenience of illustration.

Figure 8 is a detail "sectional viewtaken on'lin'e 88 of Figure '7, illustrating'the driving 'gear'as- 'sembly.

Figure 9 illustrates how the pick up roll unit is mounted to the gunnel of a fishing: boat.

Referring more specificallyto the drawings:

Our. new and improvedpick up roll for gilnets consists of end plates or frames I and 1",;spaced apart by the spacing bar 3, which'is' secured to theend platesby the 'cap'scr'ewsd and 5'. The-cap screw 4 entering the end of the'b'ar -throughthe plate, while "the cap screw 5 connects 'thebar by way of ears 6 forming part-of thebar'3, 'tothe angle portion 1 of the end plates Land 2.

A shaft '8 is j'ournalled' within bearings 910} the endplates and has the drum 'lll'keyed thereto 'by way of the. hubs I I, formingypart ofthe drum l0. Keyed tov one end of'th'e sha'ft'Bt is an overrunning clutch assembly, consisting of thelhub I2, about which rotates the. ring gear l3'i'for driving the hub 12 by way ofthe over-running rollers It.

Referring to Figures '7 andi8, an idler'pinio'n f5 forming part ofthe spur gear it: is jjourna'lle'd'to the spindle shaft IT which is secured to the. end plate 2 by way of the locking nut I8. 'Thezl'spur gear i6 is driven by theipinionigear l'9, which is keyedto the shaft '20; the said'shaft fll extending through the end plate 2 and'in'to thefiuid motor 21, which in turn. is, secured to'the end plate .2 .by the bolts v22 referring, to-Figuresjz and '1. We do not wish tobeilimite'd-to theztype, of fluidcmotor shown or to locating thesameinSide the unit.

'I'hemotor 21 drivesithe spur gearlfi'bywaxi of the pinion l9 while the pinion-1.5- drives. thering gear [3 in the direction of the arrow. When this happens the roller l4 runs up on the inclined surface 23 of the hub I2 locking the clutch assembly and revolving the drum l0 through the shaft 8, which will assist in pulling the gilnet into the boat as indicated by the arrow in Figure 9.

When the fisherman presses down on the net causing the same to engage the surface of the roller, and in the event that the fisherman can pull the line more speedily than the roller will assist him, the over-running clutch assembly will permit the roller ID to revolve with the net at a higher rate of speed than that from which it is being driven. This is an outstanding feature of our invention. In order to facilitate the operation of the fish net over the roller 10 a rubber covering IDA has been applied to the surface of the roller.

Referring to Figure 5, which is a diagrammatical layout of the fluid system used to operate the motor 2|. A fluid pump of any conventional design is indicated at 24 and is driven by the belt 25 from the crank shaft 26 of the motor 27, when the lever 28 is positioned on the quadrant 29 to cause the belt 25 to tighten. The pump 24 is mounted to the lever 28 and moves with the same. We do not wish to be limited to this particular'hook up, as there are many various ways to drive the fluid pump 24.

A fluid reservoir 39 supplies fluid to the pump 24 by way of the pipe 3i, the pump forcing the fluid through the pipe 32 to either the bypass valve 33 or the fluid motor 2!. A relief valve 34 is located between the reservoir 30, and the pipe 32 to limit the amount of pressure developed within this pipe line. 7

We will now describe the operation of driving the motor 2| from the engine 21 of the boat.

The lever 23 is moved to tighten the belt 25. -This-drivesthepump 24 pumping fluid from the reservoir out through the pipe 32 to either the by-pass valve 33 or the motor 2|. The valve -33 may direct the fluid from the pipes 32 to the return pipe 35 by-passing the motor 25 but when this valve is fully or partially shut off the motor 2! will receive a fluid supply driving the same, revolving the drum [0 as above described. The ,pipe lines 3|, 32 and 35 may be trained through any desired location on the hull of the boat in order to reach the motor 2 I.

Flexible tubing 36 is applied to the pick up "roll unit at 36A so that the unit can be moved without interfering with the pipe lines in general, as this unit is pivotally mounted at 37 to the 'vertical standards 38, which are adjustably mounted within the bases 39 secured to the gunnel 40 of the boat.

The elevation of the standards 38 are governed by .the set screws M and the angle of the lifting roll unit is determined by the adjustable supports 42 associated with the base plate. We do not. wish to be limited to this structure as other mechanical equivalents may be used, but the general idea is to be able to pivot the lifting roll assembly about the point 31 in or out of operating position. v

There may be any number of roll lifting units applied to the fluid supply line system, and this is one of the advantages obtainedby using a fluid drive for operating the roll of the lifting unit.

' Tapered guide rolls 43 are journalled to the unit for guiding the net over the top of the roller 10. These rollers are rotatably mounted to the arms 44 at 45. Referring to Figure '3, a circular disk or washer 46 is locked to the arms 44 by: I

. 4 ject of the washer 46 is to prevent the net from getting tangled up within the roller as this washer prevents the net from getting between the roller and its bearing.

Referring to Figure 2, the lower ends of the rollers 43 are journalled to the stub pins 49 associated with the cross spacer bar 33 by way of the bases 50 forming part of the bar. The gear assemblies associated with the lifting'device are housed in a cover plate 5! so that they can run in a bath of oil, eliminating the necessity of lubricating the unit while in operation.

Although certain specific embodiments of the invention have been shown and described, it is obvious that many modifications thereof are possible. The invention, therefore, is not to be restricted except in so far as is necessitated by the prior art and by the spirit of the appended claim.

What we claim is:

Driving means for a pick-up roll for gilnets, including a hollow horizontally disposed roller mounted on a shaft, one end of which extends through a supporting frame, said driving means comprising a fluid motor mounted on said frame Within the horizontally disposed hollow roller, the motor shaft extending through the frame to the outside thereof adjacent the roller shaft, a pinion on the outer end of said shaft, a gear meshing with the said pinion, a pinion secured on the shaft of the gear and rotating therewith, a ring gear meshing with the pinion on the shaft with the gear, a clutch element mounted on the end of the shaft carrying the hollow horizontally disposed roller, the clutch member having a cutout portion with one wall thereof inclined, and a roller mounted in the depression, the roller when in contact with the inclined wall of the depression frictionally binding the clutch member and ring gear together.
