ATENT QFFICE' MATHIAS TOPP, OF GJ'OVIK, NORWAY, ASSIGNOR T 0. MUSTAD & 36R, OF OSLO,

NORWAY, A COMPANY OF NORWAY AUTOMATIC MACHINERY FOR MAKING- FISHHOQKS Application filed July 25, 1928, Serial No. 295,249, and in Norway Ji'uly 30, 1927.

My invention relates to automatic machinery for making fish hooks and more especially to improvements in devices described in my I]. S. Patent No. 1,691,543, dated Novemher 13, 1928, which devices consist in means for transporting or feeding the hook blanks laterally along a work surface from tool to tool in such manner that the blanks themselves do not alter their position relatively to lo a planethrough their axis. a

In the prior patent mentioned above the holders disposed in the feeder for this purpose are so arranged, that they take part in the horizontal and vertical movements of the transporter and have no independent movement other than the opening and closing movements when freeing the blank and again taking hold of it.

According to the present invention the transporter device is simplified so that the transporter as a whole has only a horizontal reciprocating movement, whereas the holders for the blanks carried by the transporter are given the necessary vertical or nearly vertical 2 movement independent of the transporter body.

In order to explain my invention more fully I shall now describe two examples of the new transporter mechanisms embodying my invention, reference being made to the accompanying drawing; Figs. 1 and 2 being one form of carrying out the invention and Figs. 5 and 6 another form, whereas Figs. 3 and 4: illustrate in a reduced scale the mechanical movement mechanisms which may be used for controlling movements of the transporter and-the holders therein.

Fig. 1 is a vertical longitudinal section through a portion of the transporter.

Fig. 2 is a cross section on the line II of Fig. 1.

Fig. 3 is a sideview of a part of the transporter and its driving mechanism.

Fig. 4a is a cross section on the line IV of Fig. 3.

Fig. 5 is a vertical" longitudinal section through a portion of another form of transporter.

Fig. 6 is a cross-section on the line VI of Fig. 5.

As in the above named patent a machine stand A is provided with a plane horizontal work surface B constituting a series of working positions arranged in the same plane for supporting blanks and upon which surface the blanks are firmly pressed during the operation. In the present structure the blanks are fed along the surface, between the work ing steps, by means of a transporter which is reciprocated adjacent said surface in the horizontal plane of the latter and carries the blank holders which are movable at right angles to the movement of the transporter.

In Figs. 1 and 2 the blank holders consist of two blocks 20 and 21 forming together a jaw and being guided in the transporter body 19 and being controlled by a slide 23 within the transporter. This slide has a wedge,- formed or inclined face 24 on which the blocks 20 and 21 rest, and also lateral ribs 25 parallel with said wedgeface entering into corresponding grooves in the blocks. One of the blocks has a sloping front face 22 and there is a spring 26 inserted between the blocks in bores in their faces keeping the blocks apart and in contact with the front and back sides of the pocket of the transporter body in which they are inserted. The slide, the movement of which is controlled by a lever 16, fulcrumed at 17 and entering with its lower end in a notch 18 in the slide, when being moved to the left causes the blocks 20 and 21 to be lowered into the pocket and simultaneously the jaw, which they form is opened; the transporter may then make its backward movement for taking hold of another fishhook blank by a forward movement of the slide.

The movements of the transporter body and of the slide can be performed by way of two camwheels 12 and 13 (shown in the drawing of circular form, only for simplicity), the camwheel 12 cooperating with a roll 11 on the transporter body 19 and the camwheel 13 cooperating with a vertically moveable slide 14, having a groove 15 in which the upper end of the lever 16 is inserted. The backward movement of the transporter and the downward movement of the slide 14 may in usual way be effected by spring actuated levers (not shown) or otherwise. The transporter-body has its guide in the frame 10 of the machine.

In the form shown in Figs. 5 and 6 the blank holders are made in the form of levers 30, 31, fulcrumed at 32 on a vertically movable slide 35 fitting closely into a pocket in the transporter-body. This slide which is U- shaped, rests with its inclined bottom face on the wedgeformed face 34 of the slide 33, corresponding in all respects with the slide 23 Fig. 1. The lower ends of the levers 30, 31 have contact with a cross bar 36 of triangular cross section inserted in the transporter body When the slide 33 is drawn to the left from the position shown the slide 35 will move down, taking along with it the levers 30, 31 and the lower ends of the latter will go together owing to the fact that the weight of the levers below their fulcrums is greater than the weight above, whereby the jaw on their top will open and let the blank free. A movement to the right of the slide 33 will cause the reverse action, the jaws being projected above the top of the transporter and simultaneously taking hold of the blank.

What I claim is:

1. In a machine for making fish hooks, a horizontal work surface on which the blanks are to be supported for operation thereon, a transporter reciprocal in a horizontal plane adjacent the surface, a cam mounted in the transporter, vertically movable jaws support ed by the cam, means to reciprocate the cam to project and retract the jaws at right angles to the movement of the transporter, and

means to advance the latter longitudinally of the surface when the jaws are projected and return the transporter to its initial position when the aws are retracted and means to open said jaws when retracted and to close them when projected.

2. In a machine for making fish hooks, a horizontal work surface on which the blanks are to be supported, a horizontally movable transporter mounted adjacent the surface, jaws in'the transporter vertically movable at right-angles to the movement of the transporter; means to reciprocate the transporter,

' and means to project the jaws above the work surface to grip the blanks during the movement of the transporter in one direction and to retract the jaws during the movement of the transporter in the opposite direction, and means to open said jaws when retracted and to close them when projected whereby said blanks are advanced step by step along said surface.

3. In a machine for making fish hooks, a horizontal work surface on which the blanks are to be supported, a horizontally reciprocal transporter mounted adjacent the surface, vertically movable jaws mounted in the transporter, means to move the jaws at right-angles to the direction of movement of the transporter to project and retract the jaws, means operating .to 010% the jaws automatically during the projecting movement there-. of means to separate the jaws during their retracting movement, and means to move the transporter in one direction when the aws are projected and move it in the opposite dia cam face engaging the jaws to close them during their upward movement to grip the blanks, means to separate the jaws during their downward movement to release the blanks, and means to move the transporter in one direction while the jaws are raised, to ad vance the blanks on the surface, and to reverse the movement of the transporter when the jaws are lowered.

5. In a machine for making fish hooks, a horizontalwork surface on which the blanks are to be supported, a transporter reciprocal in a horizontal plane adjacent the surface, vertically movable jaws mounted inthe transporter for engaging blanks on said surface, a cam in the transporter to raise and lower the jaws at right angles to said horizontal plane, a cam face engaging the jaws to close them during their upward movement to grip the blanks, a spring interposed between the jaws adapted to separate them during their downward movement to release the blanks, and means to move the transporter in one direction while the jaws areraised, to advance the blanks on the surface, and to reverse the movement of the transporter when the jaws are lowered.

6. In a machine for making fish hooks, a horizontal work surface on which the blanks are to be supported, vertically movable slides in the transporter, means to raise and lower the slides at right-angles to the movement of the transporter, levers fulcrumed on the slides, and having upper ends constituting jaws to clamp blanks on the work surface, a wedge-shaped cross-bar engaging the lower ends of the levers operating to close the upper ends of the latter during the upward movement of the slides, said lower ends operating by gravity to separate the upper ends of the levers during the downward movement of the slides, and means to move the transporter in on: direction when the slides are raised "to advance the blanks on the work surface, and to reverse the movement of the transporter when. the shdes are lowered.

In testimony when 03 I have signed my name unto this specihcatlon.
