`SEINE-PURSING APPARATUS.

SPECIFICATION forming part of Letters Patent No. '712.370, dated October 28, 1902.

`Application filed January 25, 1901. Serial No. 44,646. (No model.)

To MZ wwm/ it may concern.'

Be it known that I, CHARLES H. GAFFNEY, of Gloucester,in the county of Essex and State of Massachusetts, have invented an Improveparts.

This invention relates to seines,- and has for its object to improve the construction of the means employed for hauling in the purselines and commonly called a purser, to the end that the two purse-lines may be manipulated as follows: both purse-lines hauled in together at the same or at dii'erent relative speeds, either purse-line hauled in while the `other remains checked, either purse-line hauled in while the other is paid out at the same or at a different relative speed, and both purse-lines paid out at the same or at different relative speeds.

Figure l shows a perspective view of a seine having a purser constructed in accordance with this invention. Fig. 2 is a side elevation of the purser. Fig. 3 is an end view of the purser, shown in. Fig. 2. Fig. 4 is allongitudinal vertical section of the purser, showing particularly the actuating mechanism for the purse-line holders or drums.

The seine a, its purse-lines b c, tackleblocks b c', and support for said tackle-blocks adapted to be secured to the boat are all of any usual or suitable construction'. The purse-lines b o, leadingyfrorn their respective tackle-blocks, are wound around the purse line holders ,which are herein shown as drums or Winches b2 c2, which are made alike, or substantially so, and are disposed in opposite ways upon and secured to a horizontal rotatable shaft CZ, which is supported in suitable bearings provided foreit in the framework.-

said straight portion or bottom b2 c3. The straight portion or bottom b3 c3 of the recess or groove will be made wide enough to receive, say, two windings of the purse-lines, and additional windings will be received upon the inclined portion b4 c4.

Asa means ot'rotating the drums or Winches ra toothed gear e is secured to the shaft 0l between the two drums or Winches, which is engaged by a pinion e', secured to a shaft e2, also having its bearings in the framework, and said shaft e2 projects through the side walls of the framework and is formed or provided with squared ends adapted to receive upon them suitable socketed cranks e4. means of said cranks the shaft e2 Will be turned, and by means of the gearing de` scribed the two purse-line holders b2 c2 will be simultaneously rotated. By providing gearing substantially as herein shown for the drums or Winches it will be seen that the ends of said drums or Winches Will be unobstructed and the windings of the purse-lines may be easily removed from and placed upon said drums or Winches.

To prevent backward rotation of the purselineholders', one of themas b2, forinstaneewill be formed with ratchet-teeth be, which are engaged by a suitable pawl 197, pivoted to the framework. l

To guide the purse-lines as they are Wound upon the drums or Winches, a pair of Vertin cally-disposed arms ff' are provided, which project upward from a cross-bar f2, secured to the framework, and upon said vertical arms friction-rolls may be placed, if desired. 'The armsff are so disposed relative to the drums or Winches as to guide the lines onto the inclined sides b4 c4, from which the lines slip, as windings, onto the straight portions b3 c3. By referring to Fig. 3 it will be nobserved that the arms ff are located approximately opposite the junction of the portions b3 b4 and c3 c4, whereby this result may be obtained. This is important, as the pinch of the several windings is obtained by the windings on the inclined portions b4 c4 crowding against the windings on the portions b3 c3.

The purser will be placed upon and secured 'to one of the seats, as g, of the boat, and as a means of detachably securing the purser to IOO said seat I have herein secured to the seat two cross-bars g g2, the ends of which project in opposite Ways from the opposite edges of the seat for a short distance, and upon the under side of the framework of the purser suitable cross-bars g3 g4 are secured, the ends of which project down over the edges of the seat and have secured to them laterally-projecting portions, which extend under the projecting ends of the cross-bars g' g2 when the apparatus is placed upon the seat and moved thereon lengthwise or toward one side of the boat. Y

In operating the apparatus it is the intention to place at least three windings of the purse-lines upon the drums or Winches, two

windings on the portion b5 c3, and one winding on the portion b4 c4, and in such event the winding on the portion b4 c4 Will crowd the windings on the portion b3 c3 against the flange b5 c5 and the purse-lines will be hauled in together at the same relative speed as the shaft d is rotated; but as the ends of the drums or Winches are not in any way obstructed one or more of the windings may be removed from or placed upon the portion b3 c3 by slipping it over the flange h5 c5, even while the drums or Winches are being revolved. When one or more of the windings is removed from either one of the drums or Winches, the remaining windings on said drum or Winch will occupy a position on the portion b3 c3, and the drum or winch may thenturn freely within said windings, or, in other Words, said windings can at such time slip upon the drum. In case it is desired that either one of the purse-lines should be paid out it will be seen that While the windings are free to slip upon the drum any pull upon the line in opposition to the pull upon the slack end will slip the windings around on the revolving drum in a direction opposite to that of the drum, and will consequently be paid out. It will therefore be seen that by the apparatus herein shown and described all the results heretofore recited may be accomplished.

I claiml. In combination with a seine, its purselines and tackle-blocks, two Winches having unobstructed ends, disposed in opposite ways on a rotatable shaft, each havinga peripheral recess or groove formed on its inside with an inclined portion, and guides for guiding the line onto said inclined portion, substantially as described. l

42. A seine-purser comprising two drums secured to a rotatable shaft and disposed in 0pposite Ways, each drum having a recess or groove formed with a portion b3, o3, disposed in parallelism with its axis, an inclined portion b4, c4, at the inside of said portion b3, c3, and a llange b5, c5, at the outside of said portion b3, c3, said recessed drums receiving a number of windings of the purse-lines, and having unobstructed ends whereby one or more windings may be removed from and placed upon said drums While said drums are rotating, and guides for guiding the lines onto the inclined portions b4, c4, substantially as described.

3. A support for a seine-parser consisting of cross-bars g3, g4, on the frame having ends which project down over the edges of the seat and which are formed with lateral extensions, the seat, and cross-bars gf, g2, on said seat having project-ing ends which receive beneath them the lateral extensions of the cross-bars g3, g4, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CHARLES H. GAFFNEY.
