Abstract
A handheld oyster and clam opener includes a pair of cooperating pivotal members. One member includes a handle and a curved toothed portion to hold a clam or oyster in position at one end. The opposing member includes a handle and a knife-like wedge along which a protruding wedge is slidable. The protruding wedge is used to open oysters and is moved to one end to open clams with the knife-like wedge both operations requiring a single stroke. A scoop mounted to the toothed portion is used to remove the clam or oyster from the shell.
Description
BACKGROUND OF INVENTION
This invention relates to a hand-operated device for opening oysters, clams and similar shellfish. The hand-operated tool includes a curved toothed member, which cooperates with an opposing member having a wedge slidably and adjustably mounted thereon for opening oysters. The portion along which the wedge slides comprises a knife like cooperating portion to open clams. The members are pivotably mounted together at one end and both include a handle portion at the other end to hand squeeze and force the clams or oysters apart in a single stroke.
The prior art includes the conventional but dangerous method of opening clams and oysters with a knife. This results in considerable loss of product since there are many oysters or clams, which cannot be opened in this fashion. The primary drawback, however, is the difficulty in gripping and opening the shellfish, which are often slippery with a knife in a safe and efficient manner.
Various devices have been developed including the disclosures of U.S. Pat. Nos. 4,133,078 and 3,846,908, which relate to handheld devices. The aforesaid patents each show two pivotal arms but the blade for engaging the oysters is not movable along an elongated arm. Further, the patents fail to disclose a device, which has no knife protrusion but includes a scoop on one of the members.
U.S. Pat. No. 3,231,930 to Berry discloses a knife having a depending wedge fixedly mounted to the blade handle but the knife is not pivotably mounted to the vertical member. The Berry opener includes a fixed stand and lacks the flexibility and speed of applicant's device.
Other patents of interest include design U.S. Pat. Nos. 196,381: 1,071,352; 189,966; and 210,032; as well as U.S. Pat. Nos. 5,482,500 and 4,348,788. None of the patents depict the unique combination, which includes a slideable wedge moveable along a wedge shaped knife-like member to open oysters or clams in cooperation with an opposing pivotally connected toothed member. The device is also safer, inexpensive and easy to use. It results in less product loss and portable and space efficient.
SUMMARY OF INVENTION
Oysters and clams are often difficult to open since the opposing shells are usually slippery and are held together by a muscle and present little or no opening to pry the shells apart.
This invention comprises a pair of members pivotably mounted together at one end and having a handle portion at the other end. One of the members comprises a curved toothed portion having a scoop like member mounted adjacent the end thereof to remove the clam or oyster. The member is curved with serrations thereon to hold a clam or oyster at one end while pressure is exerted by the other member to open the clam or oyster. The other member includes a tapered knife like portion to engage and open clams and a wedge like member slidably mounted on the knife like portion to engage and open oysters. The wedge like member is slid to one end when it is necessary to open clams.
Accordingly, an object of this invention is to provide a new and improved device for opening clams, oysters and other shellfish.
Another object of this invention is to provide a new and improved device for gripping, opening and shucking clams and oysters.
A further object of this invention is to provide a new and improved hand held device for opening clams and oysters wherein pivotably connected members cooperate to hold and open said clams and oysters.
A more specific object of this invention is to provide a new and improved hand held opening device for clams and oysters which include a curved toothed member which cooperates with a member having an adjustably mounted wedge member slidable along a knife like portion of an opposing member to engage and open oysters while the knife like portion is used to open clams with the wedge member moved to the end of said knife like portion.

DETAILED DESCRIPTION
The Invention relates to a device
10
for opening clams and oysters in a safe and expeditious manner. As shown in
FIG. 1
the opening device
10
comprises a pair of pivotably connected members or legs
11
and
12
. The upper member
11
comprises a cylindrical handle portion
13
at one end and an elongated wedge shaped portion
14
extending from the end
16
of the handle portion
13
to the other end
17
of the member
11
. The sharp edge
18
of the knife-like wedge portion
14
extends downwardly towards the opposite member
12
. At the end
17
, a portion
19
extends downwardly and includes a transverse aperture
21
to receive a pin
22
.
A wedge shaped member
23
is slidably mounted on the portion
14
of member
11
. The member
23
is designed for opening oysters and includes a tapered end wedge or knife
24
and an aperture
25
in the body portion
26
, which slides along the elongated wedge shaped portion
14
. The upper portion
27
includes an aperture
28
, which is engaged by a setscrew
29
to lock the member
23
in a fixed position against member
11
.
The lower member
12
includes a curved toothed or toothed surface
30
extending from the handle
12
at one end to the pivotal pin portion at the other end, which serves to hold one end of a clam or oyster while the adjustable wedge
23
is moved into or out of position along the wedge shaped portion
14
. The wedge knife
24
is inserted between the oyster shells. The handles
12
and
13
are squeezed together forcing the oyster shells apart. For clams, the wedge shaped member
23
is moved to one end of knife-like wedge portion
14
and the sharp edge
18
is used to force open a clam. After the clam or oyster is opened, the scoop
32
, which is mounted to the outside
33
of the curved toothed surface
30
is used to scoop the clam or oyster from the shell.
In operation, as shown in
FIG. 2
, an oyster
40
is placed in the toothed portion
30
at one end and the wedge shaped member
23
moved into position opposite the other end of the oyster
40
. The member
23
is locked in position with the setscrew
29
and the handles
11
and
12
squeezed together. The curved nature of portion
30
accommodates oysters
40
of different sizes. The member
23
spreads the often difficult to open oyster shells
41
apart in an expeditious and safe manner.
To open clams as illustrated in
FIG. 3
the wedge shaped member
23
is moved to the far end of wedge portion
14
and locked in place with the setscrew
29
. The clam is inserted with one end against the toothed portion
30
. The sharp edge
18
of the portion
14
opens the other end of the clam as the members
11
and
12
are squeezed together.
While the invention has been explained by a detailed description of certain specific embodiments, it is understood that various modifications and substitutions can be made in any of them within the scope of the appended claims, which are intended also to include equivalents of such embodiments.
