PORTABLE FIREPLACE.

SPECIFICATION forming part of Letters Patent No. 613,745, dated November 8, 1898.

Application filed April 20, 1897. Serial No. 632,967. (No model.)

T0 @ZZ whom, it may concern,.-

Beit known that I, GOTTLIEB WEIEEL, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Portable Fireplaces, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in portable fireplaces 3 and the objects of my improvements are to provide a portable stove adapted for convenience in prospecting and traveling and to provide means for supplying a forced draft to the fireplace thereof for rapid cooking and adapt itffor use as a forgewhen desirable. I attain these objects by the constructions, arrangements, and combinations of parts illustrated in the accompanying drawings and set forth in the followingspecification.

Referring to the drawings, Figure lis a perspective view of the entire device, indicating the upper air-chamber of the double bellows collapsed and the lower air-chamber iniated and adapted to supply ablast to the fireplace upon an operation of the lever; Fig. 2, avertical section of the separable stove and the bellows thereunder, with the upper portion of one of the detachable supporting-legs attached; Fig. 3, a detailed view, on large scale, of the connecting-rod guide; and Fig. 4, a cross-section of a modified form of a dished cover for the separable stove.

Similar lett-ers and figures of reference indicate like parts throughout the several views.

Referring to the accompanying drawings, forming a part of this specification, A indicates any suitable fireplace or hearth, which may be of any desirable size or form and may be adapted for support by suitable legs, as B, detachably secured thereto by bolts, as a2, which are received by slots h, whereupon the bolts may be tightened to clamp the legs B securely in place.

To guard against burning the upper ends of the legs B by heat from the replace A, strips, as 10, of non-heatconducting material may be mounted thereon to contact the shell of the fireplace, as clearly indicated in Fig. 2.

To supply a forced draft to the replace A, I have preferably provided therebelow a double bellows C, comprising collapsible airchambers C and C2, which may be supported by lugs h2, formed upon the legs B. This double bellows C is preferably constructed in cylindrical form and comprises a iiexible casing E, which consists of canvas saturated with linseed-oil or other flexible material rendered impervious to air, and heads, as D and D', which form the air-chambers C and C2. The heads D of each of the air-chambers are supplied with an aperture d', normally closed by a valve CZ, which is secured to the head by hinges 6, adapted to permit the valve to be raised by air-pressure.

A blast-conduit a is secured to and is adapted to deliver a forced draft to the fireplace A from the upper air-chamber C', into which it enters through the head D thereof, and is of suihcient length to permit of a reciprocation of kthe head thereon as the air-chamber C' is compressed and expanded in supplying the blast to the conduit, as will hereinafter be more fully explained, and to steady the head D during the reciprocation thereof upon the conduit a the guide 9 is provided and is formed in conical shape to raise the bearing thereof on the conduit above the bearing of thehead D thereon, thus providing a double bearing, as clearly indicated in Fig. 2.

To attach the double bellows C to the lugs b2, a hoop his provided and formed with a smaller diameter than the head D, which permits the head to rest thereupon when the hoop is supported by the bolts b', which are introduced through the lugs b2 and bind the hoop h between the heads thereof and the lugs, and slots h2 permit the hoop to be raised upon loosening the bolts. To secure the bellows in place upon the hoop 7L, straps h are provided and are secured to the head D and bent about thehoop.

To provide for the operation of the double bellows C, toggle-gearing F is introduced at opposite sides thereof and is pivoted to the hoop 72. and lower head D and comprise pivoted crosslinks f2,- hanging links f3, and steadying-links f4, pivoted together and adapted to movement by motion of the lever F, which is connected thereto by the rods f, which are pivoted to the cross-links f2 at the Central ptf there- Of'. two arms F2, adapted to operate the toggle- IOO The lever F is preferably provided with Y gearing F at each side of the bellows simultaneously and is fulcrumed by a pivot fr', operating in bearings g, attached to the legs B. Thus a short alternating rectilinear motion of the rods f produces a similar, but much greater, movement of the lower head D, and I am thus enabled to produce a bellows of great capacity of blast with a limited movement of the operating-lever.

The lower head D is maintained in equilibrium during the upward movement by the steadying-links j", which are preferably pivoted to the brackets f5, provided at each side of a diametrical center line of the lower head D.

It is obvious that an upward movement of the lower head D would expel the air contained in the chamber C2 by raising the intermediate air-valve d, as indicated by dotted lines in Fig. 2. This would inflate and expand the air-chamber C and also charge the blastconduit a, and as the lower head D is returned to recharge the air-chamber C2 through the lower aperture d the gravity of the head D would compress the air-chamber C', close the intermediate air-valve CZ, and expel the contained iuid through the blast-con duit a, thus supplying the blast to the tire during the return of the lower head D to recharge the chamber C2 and insuring a steady and continuous iiow of fluid to the fire during the operation of the lever F.

To increase the force of the blast expelled by the gravity of the head D', a rim h3 is provided about the head that sand an d gravel or like weighty material may be placed and retained thereupon to increase the weight thereof, and thereby expel the blast with greater velocity.

At the discharge end of the blast-conduit a may be provided a cap a, in convex form, adapted to keep coals from dropping in the conduit and having perforations 5 close to the edge for the discharge of the blast.

Upon the fireplace A may be mounted a separable stove-body H, comprising a lower shell H', of suitable sheet metal, provided with a doorway and a door l and draft-apertures k, a dished cover L thereon, a second shell H2, of less diameter than the iirst, but of similar material, over said cover, and an oven L thereon, formed by two dished covers L, and loose rings n may be introduced to steady the parts in place.

It will be clearly understood that a fierce fire might be provided in the iireplace A by employing the bellows above described,where upon cooking could be rapidly accomplished and several articles cooked at once, as water might be boiled in the dished cover L and bread baked in the oven L by the heat of the steam therefrom; or the shell H2 might be removed and a dished cover L2, Fig. 4, substituted for the cover L, whereupon any ordinaryfrying-pan or the like might be employed over the aperture 1J therein, or the parts might be differently arranged,according to the result desired, and a steady lire might be maintained without the use of the bellows by the natural draft through the doorway and out of the apertures 7s.

`When desirable to pack the article for transportation, the bolts a2 are loosened and the rods f disconnected and removed with the bracerods 2, whereupon the dished covers are nested and the shell H2 slipped into the shell H. The bellows is then collapsed after removal from the legs B and is placed in the dished covers, and after the legs B are detached from the fireplace A the dished covers and the bellows fit therein and the fireplace, with contents, slips diametrically into the telescoped shells Il' and H2. The legs B and lever F are then tied together and the entire device is packed into two small bundles of very light weight.

It is obvious that the separable stove-body may be removed from the fireplace A, which can then be used as an ordinary forge. I am thus able to provide a most desirable article for prospectors, which can be cheaply constructed and readily set up and knocked down and arranged in compact form for transportation.-

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, ism
