LOBSTER CLAW LOCK Filed Apil 11, 1935 llfm/ awwood Yand 'I are disposed at the base of the cone.

Patented Apr. 16, 1935 UNITED STATES PATENT orties 27 Claims.

The present invention relates to locks, and more particularly to locks for claws, such as the claws of lobster legs.

An object of the invention is to provide a new and improved lobster-claw lock that shall be cheap to manufacture, non-corrodibla'and very efficient in operation.

Other objects will be explained in connection with the accompanying drawing, in which Fig. l is a view in elevation of a lobster leg, with the claws thereof locked by a claw lock according to one embodiment of the present invention; Fig. 2 is a perspective of the claw lock shown in Fig. 1, before attachment to the lobster claws; and Figs. 3 to 5` are similar perspectives of modifications.

The novel lock of the present invention comprises a member in the form of a non-planar surface and having an opening 2 and

walls

4, 6, 8 and Il) of substantial extent along the opening, these walls being non-planar and merging smoothly into one another. The lock has more or less the shape of a truncated cone, the opening 2 being the upper boundary of the truncated cone, and the walls 4 and 8 forming the sloping sides. The wall 4 is of smaller Width than the other walls and has a boundary edge vI I opposite to the edge I3 of the openingv2. The Wall 8 is similarly bounded by a boundary edge 1 opposite to the edge 9 of the opening 2. The edges II The wall 8 is adapted to be positioned contiguous or adjacent to or on a claw I2 of a lobster leg I4, with the end I6 of the claw I 2 extending through the opening 2, and with the edge I3 of the opening 2 contiguous to the inner, toothed edge I 'I of the claw I2. The opening 2 is large enough to receive the end I6 of one claw I2 only, and not large enough to receive both claws. The opening 2 is of such a size that the end I6 of the claw I2 can not be inserted therein by a direct thrust, from right to left, as viewed in Fig. 1. It can be inserted only by tilting the claw.

The edge II of the wall 4 is adapted to be positioned contiguous to or on the inner, toothed edge I8 of the other claw I8 of the leg I4. The wall 4 is thus disposed between the contiguously disposed claws I2 and I8. The wall 4 is preferably of small enough width so that the claws I2 and I8 shall occupy their normal position, with the hooked tip 23 of the end 20 of the claw I8 positioned near to, and preferably in Contact with, the hooked tip 2I of the end I8 of the claw I 2. The Wall 4 may, however, if desirable, be

toothed side Il, which carries the tip 2 I.

made wider, so as to hold these hooked tips 2I and 23 separated.

The claws are secured in such position, with the wall 4 interposed, in any desired manner. In Figs. l and 2, the Walls 8 and I0 are provided with

continuation straps

22 and 24 that may extend along each side of the claw i8 and be bent over against thel convex outer edge 25 thereof. The claws l2 and i8 become thus encircled in an oval-shaped structure comprising the walls 6, 8 and I0 and the

straps

22 and 24, with the wall 4 disposed between the claws. These straps may, however, be replaced by

other straps

26 and 28, formed by cutting away from the walls 6 and I of the material, along lines 38 and 32, and reversely bending at 34 and 33, as in Fig. 3. A single, claw-encircling strap 22 may pass over the convex outer edge 25 and engage under a hook 38, as illustrated in Fig. 5. The ends of a separate, connecting, wire strap or straps 44 may extend through

openings

48 and 42 in the walls 8 and I8, as in Fig. 4. As a further modification (not shown), the ends of the

straps

22 and 24 extending beyond the edge 25 may merely be twisted together.

In all these, and other, cases that will suggest themselves, the part or parts that extend over the convex outer edge of the claw I8 will be held in position, as illustrated, without any tendency for it or them to slide down toward the end 2U of the claw i8, because any such sliding tendency is resisted by thel edge 'I engaging the outer edge 46 of the claw I2 opposite to the It may be resisted, also, in some cases, depending upon the relative dimensions of the parts, by the edge I3 engaging the toothed edge Il of this claw I2. If the dimension of the opening 2, in the direction from the edge i3 to the wall 8, is made smaller than the dimension of the claw I2, from the extreme, hooked tip of the end I8, to the outer edge 4S, there will be no possibility of the lock slipping olf the claw I2 in a direction toward the left, as viewed in Fig. 1.

It is preferred that the lock of the present invention, including the walls 4, E, 8 and I0, and the straps, including the strap 44, be made of some non-corrodible metal, such as aluminum, stainless steel and the like. As these walls are of substantial extent, they provide room for stamping hereon some designating legend 48, such as the name of the locality from which the lobsters were taken. Sometimes, one or more of the walls, or parts of them, may be omitted. The lock may conveniently be made of a single sheet of metal,

properly died and stamped, and spun, drawn, swaged or otherwise deformed into the beforementioned conical shape. It may, however, be provided with ends, soldered, welded, or otherwise integrally joined, as at 58, Fig. 3. In some cases, i` the metal is sufficiently stiff, the ends 50 may be merely overlapped, Fig. 4.

According to the present invention, the lobster claws are securely and safely locked without, in any way, injuring the meat, as is the case with the wooden pegs that are commonly driven into the joints at 52 to lock the claws.

These wooden pegs, furthermore, frequently fall out of place, which can not happen with the present invention. The claws are locked closed, but they may be locked open, depending upon the width of the wall 4 and its location with respect to the teeth or" the toothed edges I1 and i9. if the edges Il and i3 are positioned next to the :zips 2! and 23, for example, the claws may be locked very slightly open; i! they are positioned as illustrated, the claws may be locked closed as shown; and if the lock is moved further to the right, as viewed in Fig. l, the degree of locked opening of the claws may be varied within limits. It is usually desirable to position the lock substantially as illustrated, with each of the edges i i and I3 engaging between the teeth of the toothed claw edges l1 and I9 very close, or contiguous to, the extreme ends 2| and 23 of the claws. The result is a minimum of discomfort to the lobsters, without injuring any of the meat, while, at the same time, absolutely assuring that the claws will always be locked.
