DRAFT ATTACHMENT FOR COOK-STOVES.

Specification of Letters Patent.

Patented April 17, 1906.

Application filed May 22,1905. Serial No. 261,628.

To all whom it may concern:

Be it known that I, JOHN EMIL THORELIUS,

Iron Mountain, in the county of Dickenson and State of Michigan, have invented certain new Improvements in Draft Attachments for Cook-Stoves, of which the following is a specification.

This invention is intended to be applied to cook-stoves of the variety employing upwardly-projecting hoods for warming purposes; and the object of the invention is to provide an adjustable attachment adapted to create a draft or suction up through the hood and into the flue for the purpose of withdrawing smoke, steam, and objectionable odors generated during the cooking operation and which under ordinary circumstances are dissipated through the house.

The invention further relates to the means for adjusting such attachment to open and close communication with the flue and to so arrange the parts that the attachment may be fitted to stoves of the ordiary variety without materially altering the construction of stoves, thereby increasing the field of use fulness of the invention.

The invention consists in the features of construction and combination of parts hereinafter described and claimed.

In the drawings, Figure 1 is a front elevation of a cook-stove having the device of the present invention; Fig. 2, an end elevation showing the draft-hood extended Fig. 3, a sectional view of the draft-hood extended, and Fig. 4 a similar view showing the drafthood closed.

The device of the present invention is applied to a cooking-range 1 having a top 2, an oven-door 3, and upper and lower doors 4 and 5, respectively. The cooking-stove is provided with an upright hood having curved end walls 6, terminating at their upper ends in an overhanging straight portion 7, which forms a support for a top 8 and a ledge or shelf 9, adapted for the reception of food which it is desirable to keep Warm. The stove is provided with a flue 10, which passes through the shelf 9 and top 8 of the hood and leads to any suitable point for the escape of the products of combustion. The hood is provided at one side of the flue with a cross-wall 11, having therein a port or passage 12, leading into the flue, which latter is preferably squared at the point 13, which abuts agalnst the cross-wall to allow of a firm and tight joint at the point of communication through the opening 12 with the flue. The cross-wall 11, in combination with the adjoining end wall, forms a rectangular draftchamber, and the shelf or ledge 9 at this point is provided with a recess 14 in its forward edge, so that the opening from the rectangular draft-chamber to the top of the stove is practically unobstructed. The draft-chamber serves as a casing for a draft-regulator 15, consisting of an inner section 16, open at both ends and at the bottom, and an outer or closing section 17, open at the inner end and at the bottom, but closed at its outer end by means of a plate 18, provided with a handle 19 for regulating the position of the sections, which are adapted to telescope into one another. The inner section is provided at the lower edges of its side walls with guideways 20, adapted to embrace the lower edges ofthe outer or closing section, and the outer section is provided with abutments 21, adapted to prevent the entire withdrawal of the outer section; but said lugs are so positioned as to allow the sections to be telescoped to gether by the movement of the outer section.

The side walls of the inner section of the draft-regulator serve when the regulator is closed, as shown in Fig. 4, to cover the opening 12, leading to the flue 10 and serve the purpose of a damper; but in order to provide for the further regulation of the opening 12 a slide-damper 22 may be also provided for closing the escape-opening 12 at any time it may be desirable.

In use when it is desirable to start a fire in the stove the sections of the draft-regulator are preferably closed, which closes the escape-flue for the stove and allows the fire to be kindled Without difficulty and without the impairment of the stove-draft, but after the fire has become thoroughly kindled and the cooking operation begun the sections of the draft-regulator may be drawn out to any desired degree, thereby opening the port or passage 12, which creates a supplemental draft from the top of the stove and tends to carry up the flue any smoke, steam, or objectionable odors that may be occasioned by the cooking operation. At the same time the overhanging sections of the draft-regulator form an outwardly-projecting hood which is positioned at a point to most effectively collect and carry away the smoke or vapors of the cooking, so that they will not be dissipated through the house and will not interfere with the health and comfort of the inmates. The draftregulator is preferably positioned on the side of the stove immediately above the fire-box, which is ordinarily the part of the stove most used for cooking; but the suction occasioned by the regulator will ordinarily be strong enough to carry away smoke or vapors from any part of the stove-top, leaving the air pure and clean in the immediate vicinity of the stove.

It will be seen from the foregoing'descrip tion that the device of the present invention is simple in construction and arrangement and that it does not interfere to any appreciable extent with the operation of the stove and that it renders the cooking operation more pleasant and satisfactory than would be the case if noxious odors and vapors were dissipated through the house, as is ordinarily the case.

What I regard as new, and desire to secure by Letters Patent, is

1. In combination with a cook-stove provided with a raised stationary hood having a top and a ledge or shelf, a cross-wall between the top and ledge or shelf forming a draftchamber and provided with an opening lead ing to the flue of the stove, and an extensible draft-regulator open at the bottom and inner end and closed at the sides and outer end and adapted to be outwardly drawn from the draft-chamber to overhang the surface of the stove to create a draft up through the extensible draft-regulator and draft-chamber to the flue, substantially as described.

2. In combination with a cook-stove provided with a raised stationary hood having a top and a ledge or shelf, a cross-wall between the top and ledge or shelf forming a draft chamber and provided with an opening leading to the flue of the stove, and a draft-regulator consisting of an inner section open at both ends and at the bottom, and an outer section open at the bottom and inner end and closed at the outer end, the sections being adapted to telescope one into the other and adapted to be withdrawn to overhang the surface of the stove and form an extensible hood to create a draft through the draft-regulator and draft-chamber to the flue, substantially as described.

3. In combination with a cook-stove provided with a fixed u right hood having a top and a ledge or shel and having a flue-pipe passing through the top and through the ledge or shelf, a cross-wall abutting against the flue and extending from the top to the ledge or shelf and provided with an opening leading to the flue and forming a draft-chamber, and a draft-regulator consisting of an inner section open at both ends and at the bottom, and an outer section open at the bottom and inner end and closed at the outer end, the sections being adapted to telescope one into the other and adapted to be withdrawn to overhang the surface of the stove and form an extensible hood to create a draft through the draft-regulator and draft-chamber to the flue, substantially as described.
