. V CLARENCE :r. OTTUM, or PIERPONT, SOUTHDAKOTA.
. OYSTER-OPENER; 7
Application fi led. July 28,1915. Seria1No.4 2,382.
To all whom it may concern Be it known that I, CLARENCE J. OTTUM,
a citizen oflthe United States, residing at Pierpont, in thecounty of Day and'State of South Dakota, have invented certain new and useful Improvements in Oyster-Openers; and I do herebydeclare the following to be a full, clear, and'eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and usethe same. v :7
This invention is an improvedfoyster opener, the object of theinvention being to provide an improved implement of this kind which is cheap and simplein construction, is strongand durable,'and by means of g I tend rearwardly from the cross bar 7 of the handle and are pivotally connected thereto which oysters, clams and the. like may be readily and very expeditiously opened. The invention consists in the constructlon,
combination and arrangement of devices hereinafter described and claimed.
In the accompanying drawings :Figure 1 is an elevation of an oyster opener, constructed in accordance. with my invention.
' plane indicatedby the line 5 of Fig.1."
Fig. 2 is a detail transverse sectional view of the same on the plane indicated by the line a-a of Fig. 1. Fig. 8 is a similar view on the Fig. 4 is a detail elevation partly in section, on the line c-c of Fig. 1.
In the embodiment ofmy invention I pro- Vide' a. pair of opening aws 1 which are substantially 'weclge shaped and provided with points 2 at their outer ends which are adapted to be initially inserted between the members of the shell. At a suitable distance-from the points, the jaws are provided on their outer sides with notches 8 and one jaw has a stud 4 adapted to enter a bore 5 in the opposite jaw.
The handle 6 is substantially T-shaped and is here shown as made of a single piece of bent rod of suitable gage and as provided with a cross portion 7 and a pair of parallel arms 8 which are connected to the ends of the cross portion by S-shaped bends 9. The jaws 1 are provided with inwardly extend ing arms 10 which are pivotally connected to the arms 8 as at 11 so that said jaws are arranged to move toward and from each other. At a suitable distance from their points their jaws are provided on their inner sides with cam shoulders 12.
14 which hold the guide rings midwa be tween'the' arms of thejaws and also serve-to draw the jaws together and normally hold them in closed'relation as shown in Fig. 1.
mally. held inolosed relation,:as shown in Fig. 1, by the springs 14.
In using the device to open an oyster or" clam the points 2 are first inserted between I the shells and pushed in until the notches 3 are at the outer edges of the shell. The opener is then turned'by means of the handle 6 thus partly opening the shells and causing them to grip in the notches 3, and thus prevent the shells from slippingfThe rod 18 is then pushed forwardly by pressure on the knob or button 20thus causing the cam head 19 to pass forwardly between the cam shoul ders 12 and coact with said cam shoulders to a move the jaws apart, thus completing the opening of the oyster or clam. as will be understood.
While I have herein shown and described a preferred form of my invention .1 would have it understood that changesv may be made in theform, proportion and construction ofthe several parts without departing from the spirit of theinvention, and within the scope of "the appended claims.
Having thus described my invention, I claim:- I
1. An oyster opener comprising a handle,
a pair of jaws having opening points and pivotally connected to the handle for movement toward and from each other, springs to normally close the jaws and an operating rod slidably mounted in the handle and having a cam head to move between the jaws and force them apart.
2. An oyster opener comprising a handle, a pair of jaws having opening points and pivotally connected to the handle for movement toward and from each other, springs to normally close the jaws and an operating rod slidably mounted in the handle and having a cam head to move between the jaws and force them apart, the said jaws having shell engaging notches in their outer sides spaced from their points.
8. An oyster opener comprising a handle a pair of jaws having openingapoints and pivotally connected to the'handle for movement toward and from each other, springs to normally close the jaws and an operating rod slidably mounted inthe handle and having a cam head to move between the jaws and force them apart, and a spring to normally move the rod rearwardly and disengage the cam head from the jaws.
4. An oyster opener comprising a handle, a pair of jaws having opening points and pivotally connected to the handle for movement toward and from the other, springs to normally close the jaws and an operating rod slidably mounted in the handle and having a cam head to move between the jaws and force them apart, links pivotally' connected to the handle atpoints placed from opposite sides of the operating rods and links pivotally'connected to the operating rod and also pivotally connected to the first named link.
In testimony whereof I afliX my signature in presence of two witnesses.
