Applicationiled May 17,1911. Serial No. 627,802. 1

To alljvho'r 'itmdy concernl a citizen` of the' United States). residing at Evanston2 in the'county of Uinta and State of Wyoming, have invented Vcertain new and useful Impr ovements'- in` Gleaners and I1 do declare` the following to be a full, olear,'

and exact description of the invention,- such a'swill enable others skilledjin the art to .which it appertains to make and use the same.

, plan view ofthe closure for the passage be-V rThis invention relates'to pneumatic clean-l y ers,'and more' especially 'to those that e'm-U- ploy a rotary4l brush or head 'for sweeping or a suction nozzle or head for dusting; and

thevobj'ect of the same is tolproduce various improvements inafmachine of this character.-

To this endl the invention consists in andlin other .features as will appear in the following specilication and claims, and a shown in the drawings wherein- Figure. 1 is a .side elevation vof this .unifi chine complete. Fig. 2 is a central longitudinal section. Fi 3 is a plan view.` Fig.

4 is arear elevation. F ig. 5 'is a bottom tween the agitator and fan and its guides.

Fig. 6 isa detail of its spring. Fig. 7 is a perspective detail of the detachable connec tion between the brush or `'head andy its supporting sh ift.

In the drawings the numeral 1 .designates broadly.A the vcasing which .is ,of'boX-shape yhaving at aboutthe center of its length an upright partition 2 rising nearly to its'top 3 which is closed,l and in rear of this partition a bottom tupon which moves-a drawer` 5 capable of being drawn out the rear end y. of the casing .to dump the dust. Above the drawer is a longitudinal support 6 for an upright battle' 7 having throughoit holes 8, forward of this balie ,another one numbered Q depends from the top 3 and is also provided with'holes-B, and in rear of the inn termedi'ate'bale'7 another baiie .10 depends from the top 3 but is by preference made solid;` while the casing in rear of thissolid' baiiie has holes 11 covered with `niuslin 12 "projecting nose 13 whose -lower'front -end carries rollers 14 :which `will travel upon the floor or pavement being swept, and'ih. rear i of the nose and 'between'it and the uprightA Be 1t known that L'WILLIAMT. SHAFFER..

vpartition2 is an opening for the fan yet to' be; described. Obviously-this :tan draws 'the dirt and dust upward and .passes it over the upper edge of said partition 2 in rear ofwhich it'takes a tortuous 'course around the ivarious baflles and through. the holes 8, the 'air finally passing through the muslin 1-2 andv out the holes 11 and the dust and vparticles of dirt lfalling'into the drawer 5.

whence' itmay be removed from time te time;

r1 he support -for the casing\consists of a pair of traction wheels 15 fast upon a shaft 1-6. which extends; lthrough the casingl just lnfrear of the partition 2; andfrom the sides of the'casing rise handles 17 connected wardby hand like an' ordinary baby car-.-

3 at their upper lextremities'by a cross bar 18 rso that the devicev may be propelled forcertain improvements in the dust receptacle,

riage. 4' Ihe wheels 15 have rubber tires 19 so that they will cling to the floor orpaveav ment and will be paused,l tofrevolve as the device is propelled, although if their revolution is not desired the `cross bar 18 is raised and the rollers 14 support the frontend of the casing, but on the otherhand,doWnward lpressure on said cross Vbar forces the rubber tires more firmly onto" the vfloor and causes'the positiverotation of the traction wheels asfwill be understood.

fiX'ed upon an upright shaft 22 which is suitably mounted in ,the casing 'pask shown, and it revolves within a circularl opening 23 formed inthe forwardfpart-of the casing in front of the partition 2 so that all air passingupward must pass through the -fan and is thereby directed over the partition in the manner above mentioned. The opening 23 is disposed 'withnalaupright passage forwardV of, said `partition 2 and connects the upper front, portion of the dust-receptacle lhe fan `bestillustrated inFig.' 2 comy ,prises propeller blades 20 whose hub 21 is` with theupper rear portion of the; chamber beneath the' nose13. y y.

The agitator is indicated at 30V`as a brush` head adaptedto stir up ,or agitate the dirt upon the floor or pavement as it is rotated. It isby preference circular and ofa size to stand mostly under thenose 13 and to prof ject a little underthe fan as shown in Fig. 2'. .'On its upper side it carries two ears 31 through which passesa pin 82 removably cdnnectihg it with an eye 33 atthe lower end' of a shaft 34 which extends upward-through the nose 13 and is* journaled therein at 35',l

above which it rises in front ofthe casing 1 and passes through a bracket 36Y which is mounted upon the vfront upper corner of the f. casing 1 and has an upright portion 37.

which carries a bolt 38. The latter engagesI a slot 39 in an L-shaped plate 40 whose up- 'per end rests beneath the hub 41 of a gear- Wheel 42 by which the brush is driven.

Thus it will be seen that the brush head may."

be removed by withdrawing 'the pin, and some other form of agitating device substituted; also that by loosening the nut on the bolt 38 and adjusting the plate 40 the j height of the brush may be adjusted as desired, although it is intended'that itsl bristles shall stand just a trifle below the rollers 14 as shown in Fig. 2.

- The driving mechanisin'consists of a-large power wheel or gear 50 mounted fast upon the shaft 16 and engaging a driven wheel 51 which is fast Ona counter'shaft 52 journaled in a frame 53 which is' carried by the casing 1, and the inner end of this counter shaft has a beveled gear 54. The numeral 55 designates an upright shaft having a 'beveled gear 56 engaglng that numbered 54, also having a horizontal driving gear 57 which engages a somewhat smaller and rather thick gear 58 that'is mounted loosely on the fan shaft 22 and in turn engages the gear 4 2 so as to'v drive the brush. Thecentral gear wheel 58 is made rather thick sothat the gear 42 which drives the,y brushmay move up and' down thereon as necessary when the height of the brushl is adjusted; land while said gear 58 is loose on the fan shaft 22, I

connect it therewith by a backing ratchet '60' (whose description need4 not be elaborated) in order that when. the device is' being propelled forward the fan will 4berotated in the proper direction to drawin air, butwhen the device is drawn to the rear the fan will still run. forward under'its mo' mentum but will. notbe driven in a reverse direction which would draw the dust undesirably out of the casing.

In use a stiff brush is applied if a pavement orcoarse Hoor is to be swept, and a ner brush if a finer oor is to be treated, and the same isv adjusted at the proper height` with respect to the rollers 14. The operator grasps the cross bar between the handles and propels the-machine forward over the oor -or pavenent, and the power set` up by the clinging of the tires ofthe i tractionwheels'15 upon the floor or pavef so ment,';causes the driving gear 57 to rotate.

The thick gear 58 is thereby caused to turn.,

as also the. gear 42 which through the-shaft ldrives the brush 3 0 constantly in the proper4 direction;v and when the machined-is being moved forward the thick gear through the ratchetGO rotates the fan in the forward' direotiom-,whereas the fan 'runs under its 62 and nozzle 63";

momentum if the machine is drawn backward fora little distance, and at any rate vwill never Vbe driven backward.` The dust -and dirt agitated by the brush4 is sucked upwardlby the fan 'and passed over the upper edge of the partition 2, whence it takes a tortuous course through and around the b ailes 9 and 7 an'd against the baiile 10, fromA whichit falls into the drawer 5 and is removed from time to time, the clear air passing out through ,the holes 11 and the muslin 'preventing the passage therethrough of the dust and dirt. If it be desired to pass Iover somev obstruction, such as a door sill, the

-cross bar i's depressed so that the rollers 14 and brush rise xa trifle Aoff-'the Hoor; on the other hand if it be desired to scrub or brush the floor verythoroughly, the brush is ad- 'justeda little lower and then by raising the cross bar on the handlesA the bristles of the "brush will be forced downward onto the best seen in Fig. 2, the support 6 above mentioned is made tubular, its front end'- opening through the upright partition 2 into.

said passage andits rearend being threaded and closed by a removable cap' 61', and when the latter is detached a hose`62 having asi1c' tion head or nozzle 63 can be attached as 'will be clear, the form `of the latter being imma'- terial. Within the passage-beneath the .fan

is' a closure consisting of two fixed panels '66 and 66 spaced apart so as to leave an opening 70 between them, anda door 64 sliding-on the guides63 and adapted tobe pushed over said opening so as 'to close it.

-One of the fixed panels has -a spring 67 adapted'jto bear upward beneath'the door 64 when vthe latter is closed. This .isV done by grasping its handle`65 and shoving it in thedirection of the arrow along the guides 63, so that the opening 70 is closed at a point beneath the fan; after which the rotation x of the latter creates suction through the tubular' supporto and hence through the hose At this time the'brush will obviously .be raisedl olf the floor, and i .although it rotates it will perform -no func-` tion. Then the device is used as a vacuum cleaner of this type, it is propelled-*along theloor by one hand while theoperato-r holds the nozzle 63 inhis other hand and moves it along the wall or furniture or holds it in contact with otherl articles to be-cleaned` by the' suction process, the air and-.dust

takenin obviously flowingalong the pipe 62, through the tubular supporto, upward through -the fan, and thence into the drawer 4 by the course a'bove'outlined.v
