CDLIH F. HARDY, OF HARVARD, NEBRE.

DOUGH-RAISER.

specification of Letters latent.

Application filed March 20, 1916. Serial Lilo. 85332.

To all whom it may concern:

Be it known that 1, Colin F. HARDY, a citizen of the United States, residing at Harvard, in the county of Clay and State of Nebraska, have invented certain new and useful ln'i 'n'oveinents in Dough-Raisers, of

which the following is 'a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in dough raisers and it is an object of the invention to provide a device of this general character having novel and improved means whereby a heat insulating compartment is afforded which serves to re tain for a prolonged period a moderate temperature within the device in order to facilitate the raising of the dough.

It is also an object of the invehtion to providea device of this general character wherein a heat may be generated within the device and whereby the temperature within the device may be readily ascertained.

The invention consists .in the details of construction and in the combination and arrangement of the several parts of my improved raiser whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use. all as will be hereinafter more fully set forth,

The novel features of the invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a vertical sectional view taken through a dough raiser constructed in accordance with an embodiment of my invention a portion of the electric heater being shown in section; and

Fig. 2 is a view in bottom plan of the cover as herein included.

As disclosed in the accompanying drawings, A comprises the base of my improved device which consists of a layer 1 of cardboard of predetermined dimensions and havof the layers 2 of corrugated board, where by a plurality of air cells are afforded, and as herein disclosed, the layers 2 are circular in form and adapted to be snugly fitted Within the body portion B of my improved device as herein disclosed, said body portion ing imposed upon the central portion there- B being cylindrical in form and having the marginal portions of the layer 1 of cardboard ovcrlying the lower wall thereof and suitably secured thereto whereby the base A. and the body portion B are permanently secured one to the other.

The body B also comprises a plurality of layers 3 of corrugated board wherebv air cells are afforded, and the inner wall (if the body portion I5 and the base A are provided with a lining l of asbestos and the outer faces thereof are covered with a layer 5 of strong paper fiber or canvas.

The removable top C is formed in a H1311" ner substantially identical to the base A except that the under faces thereof are provided with a covering- G of felt or other compressible material so that an air-tight closure assured when the top C is in applied position. I also find it of advantage to provide the top Q with a metallic plate 7 preferably of tin so that the handle member 8 may be effectively anchored in applied position. i

The device as hereinbefore described re sults in a cabinet adapted to be of such dimensionsas to have positioned therein a pan containing dough or the like, and it will-be perceived that should the dough be made of O warm water and warm flour the temperature ofthe dough or sponge will be maintained for a prolonged period of time after the top Q has been applied. It will be par ticularly noted that by having the base A,

In the event that the dough or sponge is mixed from cold materials, a. suitable heating medium may be initially applied within the cabinet such as the container 9 of predetermined height and adapted to fit snugly Within the cabinet and upon which the dough containing pan P is adapted to be rested, said container being adapted to contain warm water or other liquid. It will be perceived however that in lieu of the container 9, a heated soap-stone may be employed, as is well known.

However, for positively heating the interiorlof tliie cabinet I prefer to employ the electric heating element E carried by the under face of the top and as herein dis-- Mid drawings.

The heating coil afforded by the wire l0 is covered with the asbestos sheets 1d and between the metallic plates 15, and said element E is held in operative position upon the under face of the top (1' through the medium'of the straps 16, hich are disposed transversely of the heating element 1) adjacent the opposite ends thereof and across the inner and outer laces of the heatin element, Headed bolts 17 are disposed through the closure member (I and through the extremities of the straps 16 and have in threaded engagement with the lower or inner ends thereof the nuts 18 which serve to clamp the heating element I l between the straps l6 and to hold the heating element in applied position upon the closure member C. it is also to be noted that the heads of the bolts 17 overlie the outer face of the closure member C.

I' also find it of advantage to provide the top C with a thermometer T said thermometer being disposed through the top and having its bulb positioned therebelow, so that the same will be arranged within tlnereot' and for this reason I do not wish to be understood as lin'riting mysell to the precise arrangement and formation of the seve. 1 parts herein shown in carrying out my invention in practice.

I claim:

It dough raiser comprising a cabinet havan claiming: a remo able closure member for said opening and extending within the cabinet when in applied position, the portion of the nsure ll'lolwbct adapted to extend within t cabinet consistine' of a plurality of laminations, an electric heater underlying the inner time of the closure member plates overlying the heater, and removable bolts disposed through the laminations of the closure member and the plates whereby said heater is held in applied position and the ialninations held against separation.

In testimony whereof I hereunto ailix my signature in the presence of two witnesses.

COLIN l HARDY.
