Application filed July 21, 190B. Serial No. 327,16].-
Be it known that I, Leas HENNING CARL- SON, a citizen of the United States, residin in the city of Lorain, county of Lorain, an State of Ohio, have invented a new and useful Clam and Oysterv Opening Machine.
My invention relates. to im rovement in machines. for opening clam an oyster shells more quickly and easily than heretofore..
The advantages of my invention consist of itsv cheapness, -ease of operation, cleanliness,
and the saving of all the liquor from the shellsopened. I attained. these objects by the mechanism illustrated in the accompanying drawings, in whichv Figure 1 is a perspective view of my invention. Fig. 2 is a top or plan view of same with part of bed-plate and end of handle broken off. Fig. 3 is detailed view of post, showing obli. ue slot in same. Fig. 4 is cross-sections. view of my invention with-dotted lines indicating position of oyster or clam shell ready to be opened by depression of knife-blade; and Fig. 5 shows sectional view of my invention with the inner side of knife perpendicular with the shear edge I), as herema ter explained. I
Similar letters refer to similar parts through )ut the several views. 1 A represents a bedlate supported by the parts a a, of sufficient eight to admit of any suitable receptacle being placed under the bed-plate to catch the liquor runningfrom the shells as opened.
Preferably the bed-plate and all parts of my invention are made of metal and of suitable size to accommodate the largest shells tobe operated on and of suflicient strength for the purposes intended. To the top of the bed-plate and rigidly secured thereto is a holder 1;, concaved or with edges projecting u ward on all sides, the back edge extending hlgh enough and beveled to form a shear edge used in conjunction with the knife (1. The end nearest the handle of the knife extends high enough to form a rest for the handle and prevents depressing the knife too far. A stop b extends up on the back side to brlng the knife in right position to form a shear cut with the edge I). A post 0 is also secured rigidly to the bed-plate A. In the top of this post is secured the hollow standard 0, cut away in front to receive the knife and rovided with a round hole on one side an an oblique slot 0 on the opposite side to receive a pin 0', extending through the inner end of holder.
the knife-blade.- The knife-blade d is wedgeshaped and theouter-end provided with a handle. In-the bottom of the holder 1) and extending through the bed-plate is a suitable hole to permit the liquor to escape from the The oblique slot 0'. iscut on such an angle as to bring the side ofthe. knife next the o erator perpendicular with the shear edge when used in connection therewith. The operation .of my invention is as follows: The oyster or clam shell can first have the edge trimmed off by the kniie and shear edge I) then set u right, its back resting in.
