Application filed June 21,

The device forming the subject matter of this application is a gurdy or winding device adapted to be used for handling lines when trolling for salmon from a launch in the open sea.

The invention aims to provide a structure of the kind described which may be connected readily with the engine of a launch, to be driven thereby, the construction being such that the operator, at will, may reel in and pay out the lines 7 It is within the province ofthe disclosure to improve generally and to enchance the utility of devices of that type to which the invention appertains. 7 lVitht-he above and other objects in view 7 which will appear as' the description proceeds, the invention resides in the combination and arrangement of parts andin the details of construction hereinafter described and claimed, it beingv understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing, from the spirit of the invention. 7

In the accompanying drawings:

Figure 1 shows inelevation, a device constructed in accordance with the invention;

Figure 2 is a top plan;

Figure 3 is a vertical section;

Figure 4 is a section taken through one of the drums, the view showing the eccentric mounting of the shafts which carry the drums; I

Figure 5 is a fragmentalsection taken through one of the brake blocks and through an adjacent portion of the drum.

The device forming the subject matter of,

this application comprises a frame, which is denoted generally by the numeral 1. The frame 1 is made up of side plates 2 and connections 3, such asbars, joining the side plates and held on the side plates by nuts 4.

The side plates 2' have outstanding bearings 5 located at points near to thegeometrical center of the plates. The bearings 5 carry dope cups 6 for the lubrication of a shaft 7 hereinafter referred to as the main shaft, the main shaft being journaled in the bearings 5. Externally of the frame 1, the main shaft 7 carries a drum 8, one edge of the drum 8 having a circumferential groove 9. The drum S'may be used for handling lines, it being necessary merely to give the line a turn or two around the drum 8 and then hold the line taut whilst the drum 1926. Serial No. 117,492.

8 turns. The groove 9 may be used for takmg power off, an observation which will be better understood when sundry other parts of the machine have been described. The shaft 7 may carry a grindstone 10. That end of the shaft 7 which is remote from the grind stone 10 is supplied with any suitable means whereby power may be taken oil the engine of the launch- A sprocket wheel 11 on the shaft 7 will answer the purpose. A spool 12 is secured to the main shaft 7 and is located between the side plates 2. "The heads 1401f the spool 12 have V-shaped grooves 15 there- On V l 'ower shafts 16 are provided.- The shafts 16 have eccentricends 17 which are mounted to rock inthe side plates 2 of the frame 1, as shown in Figure 4. Upper shafts 18 are provided, and these shafts have eccentric ends 19 which are mounted to rock in the side plates 2 ofthe frame 1. Lower drums20 are journaled upon the shafts 16. Upper drums 21 are journaled upon shafts 18. All of the end walls of all of the drums are beveled as at 22, so that the walls of the drums maybe engaged peripherally, with a tight driving engagement, in the grooves 15 of the heads 14 of the power driven spo01 12. Thevari'ousf shafts 16"an'd'18 may be lubricated by means of grease cups 23 located adjacent to the sprocket wheel 11. At the opposite side of the machine are located short handles 24 which are attached to thev eccentric ends of-the shafts 18,1ongerhan dles 25 being secured to the eccentric ends of the lower shafts 16. The side plates 2 of the frame 1 have inwardly extended upper flanges 26 and inwardly extended lower flanges 27. Upper brake blocks 28 abut against the flanges 26 and are held removably on the side plates 2 by means of securing elements 29. Lower brake blocks 30 abut against the flanges 27 and are held by securing elements 31 on'the side plates 2 of the frame 1. -The brake blocks 28 and 30 are made of any suitable friction material, for instance fibre, and they have grooves 32 into which the beveled peripheries 22 of the drums 20' and 21 are adapted to seat.

It is not necessary to go into detail as to the operationof the machine, further than to allude to one of the drums, since all of the drums are operated in the same way. The handle 25 may be swung to the right or to the left in Figure 1, the shaft 16 beingrotated. By this operation, the axis of the shaft is shifted, because the ends 17 of the shaft, which are journaled in the side plates 2, are eccentrically disposed with respect to the axis of the shaft. When the shaft 16 is shifted axially, as hereinbefore explained, the beveled edge 22 of the drum 20 is brought into the groove of the head 14 of the spool 12, and when rotation is imparted to the spool 12, by way of the shaft 7 and the sprocket wheel 11, rotation will be imparted to the drum, and a line may be reeled on the drum. hen it is desired to hold the line, the handle 25 is swung to bring the beveled edge 22 of the drum into the groove 32 of the brake block 30, and, then, the drum 20 will be held against rotation. It is possible so to position the drum 20, by means of the handle 25, that the drum will be engaged neither with the spool 12, nor with the brake blocks 30. Then the drum is free for rotation, and if a strong enough pull is exerted on the line 'whichis wound about the drum, the line will pay off the drum. There is'always a sufficient amount of stiffness in the working of the parts, and the eccentric ends 17 of the shafts are so located with respect to the brake blocks 30 and 28, that when the handles and 2d are manipulated, to shift the drums, the drums will remain engaged with the spool 12, or with the brake blocks or 28, without resorting to any supplemental or additional holding means. Ordinarily, the machine is set athwartships in the launch, and the operator stands abaft the machine and handles the levers 24 and 25 as occasion may demand.

What is claimed is:

A gurdy constructed to permit compactand located between the side plates, a pair of upper auxiliary shafts and av pair of lower auxiliary shafts, the upper and lower auxiliairy shafts being arranged in a rectangle around the main shaft and having eccentric ends mounted to lock in the side plates, drums journaled on the auxiliary shafts and located between the side plates, inwardly extended flanges on the side plates and located near to the upper and lower corners of the side plates, brakes, means for holding the brakes detachably in abutment with the flanges, the drums being disposed between the driving member and the brakes and being spaced from the brakes and from the driving member and a handle on each auxiliary shaft, the handle constituting means for lockin each auxiliar shaft inde end ently of the others, in opposite directions, to carry the drums into engagement with the driving member, or into the handles of theupper pair of auxiliary shafts being located nearer to one of the side plates than the. handles of the lower pair of auxiliary shaft being longer than the handles of the upper pair of auxiliary shafts.

In testimony that I claim the foregoing as my own, I have hereto ailixed my signature.
