OSCAR-G. SAMUELSON ,AND H'ELMER R. 'LINDQUI$T,, OF CHICAGO, ILLINOIS.

.To all whom it may concern.

Be it known that we, OSCAR G. SAMUEL- SON and HELMER R. LIND UIs'r, citizens of the United States, and residents of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Ash-Pansyand we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to certain novel features .of construction in ash pans adapted for use in stoves, ranges and the like, and consists of the matters hereinafter described and more particularly pointed out in the appended claims.

In the drawings :Figure 1 is a view representing a side elevation of a range or stove provided with our improved ash pan, parts of the range wall and of the ash pan being broken away to show the inner construction. Fig. 2 is a perspective view of the ash pan removed from the range or stove. Fig. 3

-is a transverse section through the ash pan ash pan, showing the means by which they are opcratively connected.

Tn that embodiment of our invention illus trated in the drawings, A indicates a stove or range which may be of any usual or familiar construction.

B is the grate; Q, the ash pit below the grate, and C the door closing the opening into the ash pit through which the ash pan is adapted to be removed.

D indicates the ash pan. Said ash pan is proportioned in size to fit easily within the ash pit so that it may be readily withdrawn longitudinally through the door opening, and has side walls D, D, a rear end wall D a bottom wall D and a front end wall D. The side walls D and the rear end wall D are substantially of. the same. height, which is preferably about equal to the depth of the ash pit C. The front end wall D is of less height than the sidewalls, being cut away at the top to leave an opening d.

E indicates a sifter which is mounted within the ash pan D so as to have endwise Specification of Lette-rsiPatent. P t nt d June 20, 191 Application filed January 9, 1911. .Serial No. 601,540.

- sel of substantially the width of the ash pan and having a length less than that of theash pan by anamount equal to the distance through which the sifter is to be reciprocated. The sifter E has imperforate side and end walls E E and E E and a perforated bottom E The perforations of the bottom are of such size as to permit the ashes to pass through them but 'are too small to permit the passage of the larger unburned particles. of fuel. The upper edges of the side walls D, D of the ash pan are constructed to form longitudinal rails d, cl and horizontal, longitudinal flanges 6, care formed at the upper edges of the side walls E, E of the sifter which flanges engage said rails 03', d. The sift-er thus substantially incloses the top of the ash pan so that particles falling from the grate will be intercepted by the sifter before they reach the ash pan.

F indicates a rod or bar extending the full length of the sifter and rigidly secured to the end walls thereof. Said bar projects forwardly beyond the front end wall E of the in the door G of-the'ash pit. Sai bar is provided at its forward end with means for removably attaching to it an operating bar or handle G by means of which it may be given reciprocating backward and forward movement when the door C is closed. Any convenient means may be provided for removably locking said bars together in a longitudinal direction as, forexample, the familiar means illustrated in Figs. 4 and 5.

The operation of the device is apparent from the above description: The ash pan is placed in the ash pit in the usual manner with the siftcr located as shown and described. The ashes and unconsumed parts of the fuel which :fall .from the grate drop into the sifter in the first instance, some of the ashes at the same time falling from the sifter into .the ash pan below. When the the ashes to fall into the ash pan, leaving the unoonsumed lumps of fuel in the Sifter.

. while still hot.

The door C is then opened and the Sifter withdrawn through the opening d in the front end of the ash pan and through the ash pit doorway. The unconsumed lumps of fuel may be then put back into the grate The 'sifter is then replaced in the ash pan, the ash pit door closed, and the bar G removed so that it may not become heated.

By the use of our device the unconsumed lumps of fuel may be separated from the ashes while still hot so that when they are returned to the hotcoals of the grate they are in condition to burn with little less of heat in bringing them to the point of combustion This is of great advantage since considerable heat is wasted in again heating the unconsumed particles of fuel where, as is now the general practice, they are separated from the ashes after the latter have with the grate, means inclosing an ash-pit below the grate and providing a doorway opening into said ash-pit, and adoor C105:

ing the same, said door being provided with an aperture, an ash-pan located in said ashpit and adapted for withdrawal through said doorway, said ash-pan having side, bottom and rear walls and a front wall having an opening at the top, an ash-Sifter comprising a shallow, open vessel having a perforated bottom, said sifter being constructed to inclose the open top of said ash-pan but in, and a bar rigidly connected to said sifter and projecting through said aperture in said ash-pit door.

2. In a stove and the like, in combination with the grate, means inclosing an ash-pit below the grate and providing a doorway opening into said ash-pit, and a door closing the same, said door being provided with an aperture, an ash-pan located 1n. said ash-pit adapted for withdrawal tn'ough said doorway, said ash-pan having side, bottom and rear walls and a front wall cut away at the top to leave-an opening, an ash-Sifter comprising a shallow, open vessel having a perforated bottom and having imperforate side, front and rear walls, lateral flanges formed on the side walls of said ash-pan, said sifter being of such depth that it may be withdrawn through said opening in the front -wall of said ash-pan but being shorter from front to rear than said ash-pan, a bar rigidly connected to said sifteiaand projecting through said aperture in said ash-pit door, and a handle adapted connected to the projecting end of said bar for reciprocating said ash-Sifter.

In testimony, that we claim the foregoing as our invention we affix our signatures in the presence of two witnesses, this 5th day of January A. D. 1911. I
