. CARRIER 'Archibald nMe-Reuar, Park Ridge, m. i 'Applieatiee February 1s, 1942, serial No. 431,336. k'scraimel (c1. 20s-16) The invention relates to*-ir'npr-ovlements in. carriers, but more particularly to devices'. of this characterv 'whicharef arranged and `adfil'el t0 supportand hold a.v portable suction cleaner in operative positionA and to facilitatelthe movement. of such a device and its attendant accessories from place. to place, and has for its objects theprovision of ao device of this character which will be simple in. construction, economical to 'manufacture, and highly efcient in use.

.A. further object of the inventionv is to provide a device of'this character uponewhich a portable vsuction cleanerand! its attendant accessories or attachments may be easily and. quickly mounted `insuch manner and in such `positions as will effectively' adjust the center of gravity toward increased stability.

Another object` of the invention is to provide a device of this character upon which'a portable suction cleaner` and its attendant accessories or attachments. may be mounted in such manner and in such positions as will. effectively resist any forwardly rotary motion occurring when a suction hose is attached and when such hose is used as a means of pulling the suction cleaner from place to place as necessity requires.

Otherobjects will. hereinafter appear.

'Ihe invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will bebest understood by reference to the accompanying drawing formingY a part of this specification and in which:

Figurel 1 is a planview of suchv a device embodyingA the invention;

- Figure'z is a front elevation of the embodiment of' thev inventiony having portions cut away -to betterrillustrate its construction;

*Figure 3 is a' section taken substantially on line 3"-3 of Figure 2', and by broken line insertions illustratesl the device in use with` a particular type of suction cleaner; and Figure 4 is a section taken substantially on line 4'`4of Figure 3.

' The practical embodiment ofthe invention, illustrated in the aforementioned drawing, is formed from suitableV sheet metal portions arranged in positionandfjoined, preferably by weldinginthe-usuall manner, into an integral body I0, best, shown. in: Figures 2; 3, and 4. 'I-he body I 0l comprises an elliptical` like-base plate IfI, Lthe rearward part of which is arranged horizontally, anda. forward` part I2 inclined upwardly and outwardly therefrom, the purpose of which will I be hereinafter more particularly setforth. f,

A curved wallA plate I3- is arranged vertically v uponthe base plate LI at itsrearward edge,and

a low rim I4 is similarly arranged upon the for,-

Ward portiony I?.y ofthe said base plate I-I. The

curved wall plate I3 and the low rim I4 areunited at their junctures'to `form-.acontinuous` wall around the perimeterof thevelliptical base plate I I, asis best showninFigures 1,-3, anlfl..` Aat partition I5 isfarranged vertically. upon thebase plate II in,chordalIposition-with the .curved wall I3. By this arrangement, a compartment It is provided: and the structure made. substantially rigid. by the D,n shaped tubular arrangement.: The partition I5 isl provided with ahand-hole lIlla adjacent'its` top (Figure 2)A `tofacilitate thelifting of the empty carrier, if andwhen desired. A

partition I1 having angularly disposed sideflanges |a,ef.1esser height than the partition l5 and the curved -wall I3' is arrangedY vertically; Vwithin the compartment I6 upon the basefplate IIV; asbest shown inA Figures: 13, and, 4.Y The sideanges: |18 are attached as showntothe inner side ofthe curved -wall I3., as shown; The position of the partition I'I dividesY the compartmentl I6 atits bottominto separate. ycompartments I9 5 and 20., best shown-in-Figures 1E andv 2'. The compartment I9 isadaptedto receive sections of wand tubing E, andthe compartmentlltsuitablerfor thecoiled hose H. In regard to the compartments I6? IS, and 20, it-visto be. noted, that the arrangement is such, that the upper partof compartment is sufliciently4 large: to accommodate connecting parts of both wand tubesE and the hose H which are usually largerthan the Wand tubes and hose proper, thus affording a more compact storage space for the whole. Y l

As-shown in- Figures l1, 2, andY 3, anA L. shaped vpartition 2| is arranged-in horizontal position forwardly of the partition I5 adjacent the upper edgethereof.A The endsfof thev said. partition 2ll are attached to-'the curved wall I3 and; the lower and rearward edgetherevof to the partition I5. By this arrangement, a compartmentlis` provided whichv is adapted' toreceive and` retain atomzers A commonly used in connection-with suction. cleaners. They 'partition 2I is provided with a suitablev slot 23V at 'its lower.r rearward portion adjacent the partition I5, bestshown in liiguresfl and, 3, which is adapted to hold in vertical position anV envelope` or folded filter papers F used in suction- `'cleaners of certain types. An. angular partition 2IIV is-arranged forwardly of thel partition 2I inl horizontal position, its ends being secured tothe curvedwall I3 and its bottom rear edge to the vertically arranged part 26 or the like and the compartment shielded from the heated air discharged by the suction cleaner.v

A curved wall plate-29 is secured across the inner portion of the base plate I I substantially yconcentric with the low rim I4 and forming with said rim I4 a socket I4a adapted to receive a suction cleaner C in operative position, as b est shown in Figure 3. The curved wall 2'9 extends upwardly from the base plate II `to approximately the top of the suction cleaner base C and is held in position by outwardlyV projecting side flanges 30 secured to the curved wall I3, and best shown inFigure 4. By this arrangement the two compartments 3|, the location and shape of which are best shownin Figures 2` and'4, are provided. These compartments 3| are particularly adapted for the storage of fragile containers o f fluids for the atomizer A. A-flexible pad 32` lines the inner side of the rim I4 and is held inposition by having its ends inserted in suitable recesses 33 (Figure 4). Referring to Figure 3 particularly, it is to be noted and understood that the can type of suction cleaner C, indicated by brokenA lines, has its center of gravity substantially at the axial line ofthe vertically arranged motor which is mounted just below'the blower connection B, andl that this axis lis at right angle to the bottom of the cleaner can C. As is hereinbefore mentioned, the forward portionl |2 of the base plate ,is inclined upwardly and forwardly therefrom, substantially as shown in Figures 2 and 3.v The arrangement is such that the forward part of the bottom of the cleaner can C, which is just below the suction inlet S, rests on the upper and forward edge of the said forward'portion I2 with the forward wall of the said cleaner can C against the pad 32 for approximately one-half of the circumference thereof.` The cleaner can lC is arranged just forwardly of the curved wall 2,9 which is arranged ,concentrically with the 'forwardly part of the rim I4 and extends upwardly sufficiently to contact an upper and rearmost por'- tion of the cleaner can C. By this arrangement, the weight of the cleaner C is sufficient to wedge and frictionally hold the can C in the 'socket' I4a. The cleaner can C may be easily removed, if and when desired, by lifting on its bale at B;

Portable suction cleaner devices of kthe type shown in broken line in Figure 3 are usually dragged from place to place as necessity requires during the cleaning operation by pulling on the hose H attached by a suitable connection to the suction inlet S, as indicated, With the hose H connected at this point the center of gravity is moved forward of the vertical axisof the motor due to the weight of 'the hose H and the amount of pulling force exerted. YIt' can readily be seen, that considerable skill and no little attention may be required of an operator, under certain condi-I tions, to keep the cleaner upright and in opera-1 tive position, lest' a sudden Vpull on the hose bring the center of gravity forwardly of the point of support and an unstable equilibrium be established. As before mentioned, the center of gravity of the empty carrier is approximately below the hand-hole |5a in the partition l5, and of the loaded carrier approximately in line with the hand-hold 24a in the partition 24, and best shown in Figures 2 and 3. Inasmuch as the center of gravity of the loaded carrier is located rearwardly of that of Vthe cleaner, itself, thel removal or exchange of the attendant accessories does not interfere with the pivoting of the carrier on the rearward and horizontal portion of the lbase plate The point of pivoting of the loaded carrier is located approximately on the long diameter of the base' plate |I and below the hand-hold 24a. The arrangementis such, that when a side pull is exerted by the hose H, this pivoting will allow the carrier to swing around so that a direct forward movement is obtained and the whole assembly stabilized thereby. 'I'he upwardly and forwardly inclined portion of the base plate Il affords a sled like means which allows the carrier to be readily moved over slight obstructions during such moving. e

In the foregoing specification and the drawing forming a part thereof, I have illustrated and described practical elements of embodiment of my invention which are capable of alteration, variation and modification in structure vand arrangement without departing from the spirit of my invention. I, therefore, do not wish to be limited by the precise details set forth therein, but desire to avail myself of such variations and modilicationsas fall Within the scope of the following claims.
