application' mea July v1s,
To all 'whom t may concern:
Be it known that I, RUDOLPH C. Hamme,
VLla' citizen f the United States, residing at Cambridge, in the county of Dorchester and ,which the following is a specification, ref- 'erence being had to the accompanying drawings. i
This invention relates to. certain improvements in knives and the principal object of vthe invention is to provide a cheaply coni' structed and eficient device'of this charac-' ter which can be conveniently used in cleaning fish. 'i
A further object of the .invention is the provision' of novel means for locking the blade in either open or closed position.
Further objects of the invention will appear as the following specilic description is read in connection with the accompanying drawings which form a part of this ap-V plication, and in which:
Figure 1 is a perspective view showing the blade in open position;
Figure 2 is a similar view showing the blade in closed position and with parts broken away,
Figure 3 is a section taken on the line 3-3 of Figure 1, and
Figure 4 is an elevation of the blade removed from the handle.
Referring more particularly to the drawing, 1 generally represents the body of the device which is constructed of a single piece or strip of sheet metal doubled upon itself to form opposite sides 2 and 3. In the bight or connecting portion of the sides 2 and 3 the body 1l is formed into a circular head or jaw 4, one edge of which is formed to produce the serrations or saw teeth 5 which serve to remove the scales of the fish. Immediately adjacent the jaw or head 4 the sides 2 and 3 are brought together and preferably joined by a rivet 6 which holds the parts against lateral or longitudinal relative shifting. The sides are then widened out so as to produce the handle 7 and the sides 2 and 3 throughout the length of the handle are made concave-convex with the convex upper face as shown. Beyond the handle and at the opposite end ofthe sides 2 and 3 from the head 4, the sides are bent inwardly toward one another so as to produce the parallel extensions 8 between 1921. Seriana-185,489(
which the bua end 9 0f the knifebladefio' is pivoted. 'As shown in F igure4, the butt end of theblade is'V providedr with va longitudinally extending slot llthrough which the rivet 12 passes.A Thisfrivet servesnot only as af pivot for the blade but alsoas a.
guide to' slide the blade 'into locking' engagement, aswill hereinafter 'be made plain.H At the rear end ofthe blade there isformed a longitudinally extending notch 0r^open slot ,13 and the blade has its back extended into an operatng'lever 14 similar tothe end of a razor blade. i f v Extending through the extended sides 8 1s a boltl15 provided withan ordinary wing or thumb nut and this boltisfadapted toen-l gage wlthin the 'notch 13 when the blade isj 1n open position and in the notch 16 extending laterally into the butt end of theblade, Vas shown, when the blade is in closed position.
A sshown in Figure 1, the blade is in open posltion and ther bolt 15 is arranged in the notch 13. If the bolt 15 is tightenedat this time, the blade is locked against longitudinal movement and being engaged by the bolt 12'and the bolt 15, cannot zhe accidentally closed. Whenl it is desired to close the blade, the thumb or wing nut is released and the blade moved forwardly, the bolt l2 sliding in the'slot 11, until the bOlt 15 is released from the notch 13 at which time the bilademay be folded intoI the position shown in Figure 2 with its point and edge f vlying between the side members 2 and 3, as indicated. In this position, the bolt 15 is engaged in the notch 16 which is pro-vided to permit the complete closure of the blade within the handle. If desired now the thumb nut may be operated to tighten the bolt 15 so as'to lock the handle in closed position. f y
In operation the handle is grasped by the operato-r and the jaw or head with its accompanying saw teeth pulled over the side of the fish which readily removes the scales. The instrument is then reversed in the hands of the operator and the knife blade used for cleaning the fish -in the usual manner.-
I claim:
1. In a device of the class'described, a
and the slot, said blade having a longitudinalv notch aligned With the slot, 'and a bolt passing through the extensions and adapted t0. engage inthe notch for locking the blade in open position, said .bladehavinga second notch adapted to receive the bolt when the blade is in closed position, said bolt adapted to clamp the extensions upon the blade to hold the same in closed position. *Y
2; A device of the class described comprising aY member formed of a single piece of materiah'blade holdin-g extensions formed at one end, therespective sides of said member being separated adjacent the extensions to forma handle, a blade pivoted betweenthe extensions and adapted to lie.y in the handle when closed, means permitting longitudinal movement of the blade in the extensions, and. means for locking the *bladeV against longitudinal movement.
32A "device of the class described coniprising a member formed of a single piece of material, blade holding extensions vformed at one end, the respective sides of said member being separated adjacent the extensions to form a'handle, a blade pivoted'betvveen the extensions. and adapted to lie in the hanprising a pair of opposed sides having extensions, a blade provided With a slot at one end, the extensions being spaced equal to and receiving the slotted end ofthe blade, a pivotpin passing through the'slot and fixed.v in said extensions, the extremityofv the slotted end of the lblade having an elon.`
gated notch adjacent one end of and aligned With the slot, the slotted endv having aV curved Ynotch substantially laterallyof the blade and having its crotch adjacent to and( alignedvvith the other end of theslot, and.
clamping means including a rbolt` ixedfin saidextensions and With which either notch may engage to hold the blade either open or closed. i
In testimony whereof I hereunto affix my signature.
