JAMESROBERT PEIFR, F SHEPPTON, PENNSYLVANIA.

FAN-BLOWER.

Be it known that I, JAMns ROBERT PnrrER, a citizen of ythe United States,` residing at Sheppton, in the county of Schuylkill and State of' .Pennisi lvania have invented certain new and useful Improvements in Fan- Blowers; and I `do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains` to make and usethe same.

My invention relates to new andy useful improvements in fan blowers and my object is to provide a fan and means to operate the same and assemble the casings around the parts whereby the structure will occupy but a minimum amount of space. l

A further object is to provide avent for the admission of air into the fan housing.

A further object is to provide means for attaching the blower touparts of a stove. f

A further objQQLiS..toiprovide means for ""conve'ying'the air from the fan housing to a point below the grate in the fire box. And a further object is to\ provide kmeans for covering the openings inthe air conveying means whereby ashes and the like Awill beexeluded therefrom. f M l vOther objects and advantages will be hereinafter set forth and more particularly pointed out in the accompanying specification.

ln the accompanying drawings which` are made a part of this application, Figure 1 is a sectional 'view through heatingvstove, showing my improved fan mechanisml attached thereto. Fig. 2 is an end elevation of the fan mechanism removed from theV stove. Fig. 3 is a plan view 'of the pipe employed for conveying the air to a, point below the grate, and Fig. 4 is an enlarged transverse sectional View thereof.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, l indicates a stove which may be constructed in the usual or any preferred manner employed for heating or cooking purposes, 2

indicates the fire box and 3 the grate therein.

Secured at any suitable point to the wall kof the stove and preferably in the rear thereof ismy improved form of fan construction comprlsing a housing 4, the outer wall 5 of which is removably secured to the remaining portion of the housin said wall being held in position by intro ucing bolts y Appiiieatioptied December i1, 1915. serial No. 66,392.

l Specication of Letters Patent. Pntnted June 13, 1916,

i orricn 6 through the inner wall and threading the ends thereof into fillets 7 on the inner face of the outer wall. Rotatably mounted in bearings 8 'at the axial center of the housing is a shaft 9 to which is attached a fan 10, said shaft extending through and beyond the outer wall 5 and has a pinion l1 fixed thereon with which meshes a driving gear 12, said driving gear being likewise mounted upon a shaft 13 one end of which finds4 a bearing in the outer` wall 5, while the opposite end projects through the wall of an auxiliarycasing 14, the extreme outer end of theshaft 13 having a crank 15 attached thereto by means of which rotating motion is imparted to the driving gear.

The auxiliary casing 14 comprises a circularplate 16, the peripheral edge of which is provided with the iange 17 which pro- .jects at right angles to the circular plate,

the lower portion of said flange resting against the face of the outer wall 5, while the upper portion thereof projects above the housing 4 andtelescopes with a iange 18 of a semicircular plate 19, said semicircular plate havinga flange 20 at its inner edge which rests upon the edge wall of the hous-y ing 4 and is secured thereto in any preferred manner, said housing and casing forming a complete covering for the fan and gears and by arranging the gears in the manner shown, the fan construction may be assembled in compact formation. l

In'order to admit air into the housing 4, an opening 21 is formed through the outer wall' 5 which opening is substantially crescent shape and is `positioned immediately below the edge of the auxiliary casing 14 solthat the air will be admitted to the fan at a point yadjacent its axial center. The housing 4 is provided with an integral nozzle 22 which is preferably positioned below the housing and has connected to itsV lower'end a pipe 23, the coupling 24 employed for securing the pipe to the nozzle' being so constructed that said pipe may swivel in the coupling and be directed at variousl angles as occasion may require.

The pipe 23 is preferably directed at right angles to the vertical trend of the housing and is adapted to be introduced into the stove at' a point below the re grate, the upper portion of said pipe having a plurality of ports 25 therethrough through which the air escapes and by placing said ports in the upper face of the pipe the blast` of air will be directed through the grate and into di-V rect'contact With the kfuel resting thereon.

ln order to prevent ashes, or the like, from Venteringthe'ports 25, as the ash is shaken `from the grate 3, a shield 26 is positioned over theface of the pipe 23, said shieldbeing inthe arc of a circle and fitting the outer periphery of the pipe, transverse slots Q7 beingY formed in the shield adjacent its ends throughV which project studs 28 carried by the'pipe '2.3 and by means of which the rotating movement of the shield upon the pipe is limited. The movement of tle shieldris regulated by means of a lever 29 .which is preferably rfformed integral With Y one end of the shieldand projects exteriorly of the Wall of the stove sothat the lever may be readily grasped tofswing the shield to a position toy cover or uncover` the ports', the

weight of the shield'serving to hold the same Y against casual rotation.`

The prime object of Vmy invention is to provide a blast of air to increasethe heating capacity-of the fuelV Within the fire box` so that the 'temperature Within the ,stove may be greatly increased in a very short period oftimeV and the device is further applicable forcausing the fuel to readily ignite When theviire is first started andby introducing the'pip into the ash receiving comlll'illllll ofthe stove immediately belowrftli grate on Whichthe fuel is resting-these results'vvill be readily accomplished. l Y

When Va blastof airis to be directed through theY grate and'intocontact With the w fuel, thelever 29 is'depressed, thereby rotating the shield 26around the pipe 23 the full l length of the slots27 and thus uncovering the'pcrts ,25.A The crank 15K is then rotated Whichwill operate the fanV 10V and force the Y air through the pipe 28and ports 25, andin view of the fact that the opening "21 is placed adjacent the axial center of the fa .Copies o'f'this patent may be obtained'fo a r,suction `Will be caused within thehousing i when the fany isl rotated and a constant supply of air drawn into the housing.'

As soon as the temperature Within the stove has been raised fto the proper degree Y byineans of the'forced draft, the' shield 26V is rotated in the jopposite direction through the medium of the lever29 and the ports 25 covered over so that the ashes falling from the iirebox Will be prevented from entering the ports 25 and clogging the interior ofthe Vpipe 23.

Having thus fully described my invention What I claim as new and desire to secure by LettersPatent of the'United States, is

l. Yln afanblotver for stoves, furnaces andV the like, the combination With aV housing having a dischargenozzle, a fan'mounted in said housing, and means to operate said fan to direct a blastV of air throughthe nozzle,

of'a pipesivivelly' connected, to said nozzle for adjusting the angular relation of said pipe relative to saidnozzle, said pipe havj ing a plurality of Vports therein, a curved solidV shield embracing the upper surface of said pipe and having transverse slots therein adjacent its ends, studs extending through said slots and into theV pipe 'for limiting the adjustment of said shield, andra VleverV con'- nectedtosaid shield by means of Which lthe shield may be vmovedftfo position to cover or uncover saidfports.A

2. Ablower for stoves, furnaces and the like,comprising a housing having a removablefouter iva'll, said router Wall having an air receiving opening therethrough, ashaft rotatablyfmounted in saidv housing, a fan carried by said shaft, a pinion fixed to said shaft, a` driving gear meshing with said `pinion, an auxiliary casing surrounding said drivinggearand pinion, said casing comprising a circular plate having an angularly extending yfiange at Vthe peripheral edge thereof, a seinicircular plate having a flange thereon adapted to telescope'vvith; the flange of the first plate,y means to connect said plates together `and t'o said housing, a crank for operating said driving gear for revolving said fan, and means to convey'the blast y of vcreateil by said fan to points beneath agrate.
