Patented Oct. 8, 1935 UNITED STATES PATENT FFICE HONEY UNCAPPING KNIFE Application June 20, 1933, Serial No. 676,687

5 Claims.

This present invention relates to improvements in a honey uncapping knife and appertains particularly to a heated device for this purpose that is light, handy and convenient.

An object of the invention is to provide a honey uncapping knife heated by a resistance element in an electric circuit so that the same is kept warm without requiring attention by the operator or offering delay, obstruction or hindrance to his work.

A further object of the invention is to provide an electrically heated honey uncappingi knife whose element is removably housed within the blade and whose lead wires extend out through the end of the handle. v

Al further object of the invention ls to provide an electrically heated honey uncapping knife of the nature and for the purpose set forth that is characterized by structural simplicity, durability, efficiency and low cost of production whereby the same is rendered commercially desirable.

To the accomplishment of these and related objects as shall become apparent as the description proceeds, the invention resides in the construction, combination and arrangement of parts as shall be hereinafter more fully described, illustrated in the accompanying drawing, and pointed out in the claims hereunto appended.

The invention will be best understood and can be more clearly described when reference is had to the drawing forming a part of this disclosure wherein like characters indicate like parts throughout the several views.

In the drawing:-

Figure l is a plan view of the knife;

Figure 2 is a vertical longitudinal section thereof as taken along the line 2 2 of Figure 1;

Figure 3 is a transverse vertical section therethrough, as taken on the line 3-3 of Figure 2, looking in the direction indicated by the arrows;

Figure 4 is a transverse vertical section through the handle as taken on the line 4-4 of Figure 2, looking in the direction indicated by the arrows;

Figures 5 and 6 are plan views of alternative forms of resistance heating elements; and

Figure '7 is a detail plan of a slightly modified form of handle end with the extension cord extending therefrom.

The knife comprises a blade I0, sharpened along both edges with a longitudinal trough II that is substantially V-shaped in cross section running the length thereof and rounded up and pointed at its outer end I2. The handle or inner end I3 is parallel with but upwardly offset from the blade by an inclined intermediate portion I4.

y handle end I3 of the knife I Il.

Encasing the trough of the blade I0 is a raised arch shield or cover I5 rounding up from the pointed outer end I2 and joining the inclined olfset portion I4. This cover I5 is soldered to the knife blade Il] around its entire periphery. 5

For the heating element, a resistance wire I6 is Wrapped in a mica or other insulating jacket II whose opposite longitudinal edges are compressed and held by inturned flanges I8 of a reinforcing base plate I9. In the element shown in Figure 10 5, the far end of the resistance wire grounds to the base plate I9 and the two lead wires 2Q and 2l at the inner end connect one to the inner end ofv the resistance wire I6 and one to the base plate I9 respectively. In Figure 6, the resistance wire 15 I6a returns on itself so that the lead wires both connect to the spaced ends of the resistance element at the inner end: The mica jacket I'Ial and marginally flanged base plate I9a being similar to those already described.

The angular offsetting portion I4 of the knife IIJ is horizontally slotted as at 22 just above the blade to accommodate one of these heating elements that is removably inserted therethrough, the anged edges of the base plate I9y or IIla 25 frictionally engaging tightly againstA opposite sides of the knife trough I I at the junction thereof with the cover I5. The heating element preferably extends the entire length of the knife blade III with only the lead wire connections exposed 30 exterior of the slot 22.

The handle 23 is formed in two vertically 4separable halves that engage opposite upper and lower faces of the offset handle end I3 of the knife. These are held tightly together by longitudinally spaced countersunk vertical fastening means such as the conventional nuts and bolts24, as shown; that extend through registering perforations in the handle halves and the handle end I3 of the knife. Along its upper side, the under half of the handle 23 has a central longitudinal groove 25 in which the lead wires 29 and 2| are carried and also includes a depending lip 26 at its forward end that follows down the offset portion I4 and covers the rear protruding end of 45 the heating element, being similarly grooved and suitably recessed to accommodate the same. The rear or free end of the handle 23, in Figures l and 2, is shown provided with a. two prong plug receiving socket 2'I formed integral with the 50 In the modified form, shown in Figure '7, the two lead wires 20 and 2| just extend through the handle 23 and are terminally provided with the male part of a two piece extension cord connection 28.

In use, this knife is easily operated in the ordinary way. The heating element is connected up in a circuit with either a battery or the usual electric source where such is available, a proper strength resistance element being employed but since they are interchangeable, the structure of the knife apart from the element is not varied in any way. The extension cord may extend directly outwards from the handle as shown in Figure 7, or plug therein as illustrated in Figures l and 2. In either case the cord will not interferel in any way with the easy operation of the knife and since it is kept heated without any attention from the operator and its heating occasions no inconvenience, more and better work can be accomplished.

From the foregoing description taken in connection with the accompanying drawing, it will be manifest that a honey uncapping knife is provided that will fulfill all the necessary requirements of su'ch a device but as many changes could be made in the above description and many apparently widely different embodiments of my invention may be constructed within the scope of the appended claims without departing from the spirit or scope thereof, it is intended that all matters contained in the said accompanying specification and drawing shall be interpreted as illustrative and not in a limitative or restrictive sense.
