INVENTOR, UJLEETHORFINNSSOM BY i Patented June 9, 1931 OLE H. THORFINNSSON, OIE BALTIMORE, MARYLAND PEEL-BLA E,

Application filed March 5,

This invention relates to peel-blades, and especially to an improved construction and combination which prevents the peel-blade from warping to any appreciable and detrimental extent.

The main object of this invention is to generally improve upon a construction of peelblades such as used by bakers for handling bread, cake and thelike in the ovens, and for removing it from the oven.

A further object is to provide an improved peel-blade of this characterwhich does not sacrifice any of the important and essentialfeatures of the most satisfactory peel-blades now on the market and in use.

Other objects and important features are pointed out or implied in the following details of description, in connection with the accompanying drawings in which:

Figure 1 is an edge view of my improved peel-blade.

I Figure 2 is a side View or top plan view.

Figure 3 is a central sectional view along the line 33 of Figure 2.

Referring to these drawings in detail, in

, which similar reference characters correbroad sides of the plate 5, these strips 8 and 9 being substantially parallel with one another and with the edge portion 7 They are wedge-shaped or tapered, as shown, so they can be quickly, easily and tightly driven intothe grooves. Screws or glue or both may be used to hold them securely in place.

More specifically, the plate 5 is formed of wood which has its grain extending from the handle-engaging end 6 to the edge portion 7, and dovetail grooves 10 and 11 have the strips 8 and 9 fitted therein, the edges of these strips being beveled, and their outer 1929. Serial 110,344,535.

surfaces being flush withthe outer surface of the plate 5. --The grain'of the strips 8 and 9 extend lengthwise thereof, and atright angles to the grain of the plate 5. The grooves 10 and 11 are spaced from one another adistance greater than the thickness of the 'peel-blade, so they can be sufiicientl'y deep without combining to detrimentally 7 weaken the peel-blade.

The contour and general shape of this peelblade is substantially the same as that of peel-blades whichhave been known and used prior to' this invention, the handleengaging part6 being provided with bores 12 through which pins (not shown) extend, which pins" also extend through the handle (not shown) 1 for securing the handle in the slot 13.

However, the oppositely disposedstrips 8 and 9 are important 'features'of this inven tion, for it is well known that wooden peel-c blades and the like are likely towarp,in.

consequence of the heat anclother influences i to which they are subjected, and the warping'ofthe lifting edge portion"? renders the peel-blade inefficient, and even ineffective when the warping-is considerable.

Moreover, it is known that peel-blades and a the like are likely to become brittle in consequence of the intense heat to which they .7 are continually and repeatedly subjected, and are likely to split in the direction of the grain. The strips 8 and 9 effectively prevent the peel-blade fro-m splitting, and tend to prevent it from warping. It is well known, however, that the shrinkage of wood, is greater across the grain than longitudinally of thegrain, and therefore, if both strips were on the same broad side'of the plate or peel-blade, they would tend to cause the peelblade to warp. However, by the strips 8 and 9 being on opposite sides, each of such strips counteracts the effect of the other, at least to a very considerable extent, so the warping,

of the peel-blade is reduced tothe minimum, consistent with the reenforcing effects of the strips 8 and 9. a

The reenforcing strip 9, while tending to prevent warping, also tends to prevent lateral shrinkage of the peel-blade, while the edge portion 7, being unprovided with'such reenforcing means, would be likely to warp and crack, as has been experienced by persons using peel-blades. To offset this difficulty, I provide bores 14 at a distance from the edge portion 7, and slightly spaced from the strip 9, and I provide slots 15 from the extreme edge of the part 7 into the respective bores 14. Between the slots 15, relatively narrow tongues are provided, constituting the relatively thin, tapered, and sharp edge portion 7. The outer ends of these tongues are in straight alinement with one another, as clearly shown in Figure 2. By provision of the slots 15, the tongues of the part 7, being relatively narrow, do not warp to any appreciable or detrimental extent, and the circular openings or bores 14c eifective-ly prevent the slots 15 from being extended in consequence of shrinkage of the peel-blade.

While I have specified wood as the material for the parts 5, 8 and 9, because wood a has been found more satisfactory than any other material, for the construction of peelblades, Ido not wish to limit my patent protection to this particular material nor to the exact details of construction and arrangement or combination shown, for appropriate changes may be made within the scope of the invention without departing from the spirit thereof, as claimed.

What I claim as my invention is In a peel-blade, the combination of a wooden plate having a relatively sharp lifting edge and an opposite handle-engaging edge and being formed with a groove across the grain of the Wood and having slots extending from the lifting edge toward said groove, the said plate having circular bores therethrough at points between said lifting edge and groove and in open communication with the said slots respectively, for the purpose specified, and a reenforcing strip fitted and secured in said groove.

In testimony whereof I affix my signature.
