1 Claim.

This invention relates to a quick acting telescoping landing net which is capable of being expelled instantly into operative position and which is easily retracted'intoits casing.

It is an object of this invention to provide a easing into which thelanding net may be held when not in use, but-the'net can be instantly expelled from the casing into full open position without any damage being done to the net.

It is another objectof this invention to provide a cylindrical casingfor retaining a landing net and its support means therein, and propulsion means including a spring actuated piston for instantly expelling the landing net and its frame members from the casing, of cord means having its opposite ends associated with the bottom of the net and the frontof the casing with a guide tube for the'cordsecuredto the front end of the piston.

A still further object of this invention relates to a quick acting landingnet means in' which a casing is provided for housing? the met when not in use, of frame membersfor' supporting the net having flexible guidemeans for aiding in expelling the net from the-casing an'd for protecting the net from damage-by the'frame' members when the net is being drawnintothe-casing.

Other and further objects will become apparent from the detaileddescription and the subjoined claims.

The accompanying drawings illustrate the invention.

Figure 3 is a sectional view taken on line 3-3 of Figure 2 showingthe guides in the front end of the casing for the frames for the net.

Figure 4 is a sectional view taken on line 4-4 of Figure 1 disclosing the pivot or hinge means for front end of the frame members of the landing net.

Figure 5 is a fragmentary: view of the piston, showing the tube for the c'ord for-the landing net and the pivot meansfor therear 'end of" frame members of the landing-net Referring in detail to the drawings I0 is the telescopic landing net means which comprises a cylindrical metal casing I 2 having a cap 14 removably mounted on one end with an apertured projection by which the net means [B may be suspended from a hook on the fishermans belt, etc.

The top of the casing I2 is provided with a longitudinal slot [8 which extends from a point slightly ahead of-the cap end I4 of the casing to near the opposite end of the casing. A collar 2t provided with a chamber 22 whose diameter gradually becomes greater from the rear end toward the front end of'the collar 20' except for a small circumferential portion 2| at its front end which is of the same diameter throughout its length of receiving a round metal closure plate 50.

A piston member 241s mounted for sliding movement inside the casing12. A finger element 25 is secured to 'the piston 24 by securing means extending through slot l8 and provided with a shank portion 28 and an elevated element 30 provided with a'fla-t' face 32* projecting beyond the inner end of the shank'2B. A relatively large compression spring" 34 is-carried in the casing l2 between the cap !4 and the rear end of the piston 24 to provide the expulsion means for automatically extending the fishing net 54 of the device when the net is released from the casing It). A small hollow tube 36 being open at both ends consisting of a front straight portion extending forwardly and downwardly from the front of the piston 24 and a hook formed. in its rear portion and its rear end also extending forwardly and downwardly from the front end of piston 241s securedby solder 31 to thefront end of the piston 24 for apurpose to be set forth hereinafter; A pair of spacedbrackets 38-33 are also secured to the front end of the piston 24' and pivot pins 40-46 arevertically mounted in the brackets 38-38 with a metal loop42 encircling each pin 40.

A pair of frame members 44-44 or collapsible spring bows of thin resilient metal have their inner ends respectively secured to the loops 42-42 carried by pivot pins 40-40 with their opposite ends secured to metal loops'4B-46- encircling pivot pins 48-48 vertically mounted in brackets on theround metal plate 59; A plu rality ofspaced apart apertures are appropriately 3 formed in the center of each of the collapsible spring bows or frames 44 extending from end to end thereof. A pair of threads 52 are threaded through the plurality of spaced apart apertures in the frames 44-44 securing the upper open end of a landing net 54 to the inside of the frames 44-44. A separate elastic or flexible guide member 56 of rubber or the like extends above and below the upper and lower edges respectively of each of the frames 44-44 and is secured by the threads 52 at their front portions to the inside of the frames 44-44 adjacent their inner ends. The inner portion of each of the elastic guides 55 is secured to the frames 44-44 as at 58, and their inner ends are secured to the front of the piston 24 adjacent the tube 36. The elastic guides 55 prevent the metal frames 44-44 from cutting the net 54 when the net is retracted into the easing I2. The elastic elements 56-56 also aids to wipe or push the net 54 and control cord 50 clear of the casing I2 when the net is expelled from the casing. A cord 55 is secured at one end to the bottom of the net 54 with the opposite end threaded through the tube 35 and secured to the collar 20 at 52. The cord 55 is of sufficient length to extend from the tube 36 to the bottom of the net 54 when the piston 24 is positioned at the front end of the casing I2 and the net 54 is in full open position as shown in Figure l of the drawing.

A housing 64 is carried on the outside of the casing I2 near its rear end and latch 55 is pivoted to the housing with a small coil spring 58 normally urging the catch 6'! of the latch 65 through an aperture in the casing I2.

When the fishing net 54 is not being used to receive a fish from a fish hook or the like, the left thumb of a user engaging the fiat surface 32 of the finger element 26 pulls the piston 24 rearwardly in the casing I2 against the pressure of the compression spring 34 until the catch 57 on latch 66 engages the front end of the piston 24 for holding the net 54 and frames 44-44 in a retracted condition in the casing I2. The net 54 will remain in the casing as long as the latch 56 in allowed to retain the piston 24 in its retracted position therein.

A guide groove 'II] is formed on opposite sides of the collar 20 on the inside thereof to guide and hold the side frames 44-44 in proper a1ignment in the casing I2 when the net is being withdrawn into the casing. A smaller groove (2 in each of the larger grooves 10 receives the edges of the threads 52 on the outside of the frames 44-44 either when the net is retracted into the casing or when the net 54 is expelled from the casing to prevent cutting or undue wearing on the threads 52.

The enlarged portion of chamber 22 at the outer end of the collar acts as a shuttle at its lower side by engaging the net 54 as it is being withdrawn into the casing I2 and pushes or wipes the net 54 toward the center of the chamber 22 between the flexible metal guide frames 44-44 thus preventing the guide frames 44-44 damaging the net 54. When the finger element 26 is pulled rearwardly of easing I2 retracting the net 54 into the casing, the control cord GE! is pulled into casing I2 and the end of cord 60 attached to the bottom of the net 54 pulls the bottom of the net up towards the mouth of the collar 20 and the lower end of the net 54 is gradually fed into the casing I2 along with the upper portion of the net insuring that the net will not bunch at the front of the collar 20 and then the plate 50 can completely close the front end of the casing I2. The draw or control cord tube 36 acts as a guide for the cord 60 and tube 36 also aids in holding apart the frames 44-44 from each other when collapsed in the casing I2 so that the control cord 60 will not be bound between the frames 44-44. The net 54 corresponds substantiall in length to the length of one of the bow springs 44 and control cord 60 corresponds substantially to the length of the net 54 so that when the landing net is telescoped into the casing I2, the frames 44-44, net 54 and cord 60 are completely retracted into and housed in the casing I2. I

The cover plate 50 completely covers the opening in the collar 20 when the net 54 is withdrawn into the casing I2.

When a fisherman wishes to use the net device and it is collapsed in the casing I2 he merely actuates the latch 66 releasing it from engagement with the piston 24 and the coil spring 34 automatically and instantly moves the pistonv 24 forwardly in the casing I2 thus expelling the frames 44-44 with the attached net 54 from the front end of the casing I2. The resilient. spring bows or frames 44-44 expand thus moving the net 54 to full open position ready for in-- stant use when needed by a fisherman. An in-- termediate portion of the finger element 26 en gages a stop member I5 formed on the collar 20- for limiting the forward movement of the piston. 24 in the casing I2.

The front cover plate 50 acts as a hinge plate for the resilient frames 44-44. A hook 8D is.

secured to the casing I2 and it is used for slipping: the device onto the belt of a fisherman.

It is to be understood that changes in the size, shape and dimensions of the device may be resorted to but all such changes are deemed to. fall within the scope of the appended claim.
