' New York, N. Y.

Application July 13, 1936, Serial No. 90.343 11 Claims. (01. 280-01) This invention refers to dollies and more particularly to a new and novel form of dolly for supporting portable vacuum cleaners.

.Certain portable vacuum cleaners are now.

made' to he slid on the floor or carried by a handle. when slid on the floor, the usable length of hose is shortened as the cleaning attachment is usually carried waist-high. Furthermore, when carried by hand, only one hand is available for manipulating said attachment. This invention comprehends furnishing a peculiar form of dolly carriage or fabricated structure for clampably supporting vacuum cleaner units of'the type above described, which combination permits freer use of a vacuum cleaning attache ment and at all times permits the use of bot hands for manipulation thereof.

The invention further comprehends furnishing suitable fixtures on said carriage or dolly for 20 supporting the various cleaning attachments when not in use, said attachments being supported within easy reach of the operator.

This invention further comprehends furnishing a foldable or collapsible form of carriage or 25 dolly for supporting portable vacuum cleaner units which may be folded or collapsed into a comparatively small space for storage thereof, after said unit has been removed therefrom, said dolly also being arranged to support said clean- 30 ing attachments thereon when in the folded or collapsed position. Y

The invention further comprehends novel and peculiar modes for clampably holding vacuum cleaner units onto said dolly whereby the move- 35 ment thereof from place toplace during vacuum cleaning may be effected by pulling on the vacuum cleaner hose attached to said unit or by pullingthe electric attachment cord attached to said unit.

40 The invention further comprehends furnishing a novel form of collapsible dolly for clampably supporting vacuum cleaners wherein said carriage or dolly may 'be locked in either the open or collapsed position. I

A Otheradvantages will be apparent as the de- -"scription of the invention progresses and the hovel featuresthereof are pointed out in the specification and claims.

Referring to the drawing wherein like numer- 50 als indicate corresponding parts, Figure 1 is a perspective view of the embodiment of the invention showing a carriage or dolly in the open position, and Fig. 2 is a sectional view of the same in collapsed position taken on line 2-2 of '55 Fig. l, and Fig. 31s an end elevational view of m carriage or reticulated structure I comprises rodlike uprights 2, to the lower end I of which are secured castors 4, the upper ends thereof being formed as clamping portions 5 covered with resilient sleeves or housings 6 arranged to engage a vacuum cleaner unit. as I, when inserted in 5 clamping relation to said clamping portions 5 as shown.

Top and bottom longitudinal or side bars or members 8 are rigidly clamped to rods 2 by clamping members 9 surrounding said rods,

riveted to or otherwise suitably secured to each end of said side bars.

Transverse or end bars ill have hinge or clamping members rigidly secured to each end thereof, arranged to hinge or pivot on rods 2 each side of clamping members 9.

Hinged to one lower side bar 8, by hinge i2, is locking latch, plate or spacing member 63,

having resilient latching end It includingslocking projections i5 and i6 arranged to interlock with locking projections H on side bar 3 when 1 said carriage or dolly is in the open position. Locking projections 55 and i6 are also arranged to interlock with the lower portion of side bar 40 when said dolly is in the fully folded position as shown in Fig. 2.

Spacing member i3 supports cleaning attachment supporting member or board or plate it having aligned or spacing members 20 secured adjacent each end thereof, said aligning members engaging the inner side of transverse or end rails ii) when latch it is interlocked in the open position as shown in Fig. 1. Cleaning attachment supporting member i8 supports cleaning attachment studs or holding members Iii over which various cleaning attachments, as 2i, may

be placed for supporting the same when not in use.

Locking member 23 of U-shaped form is arranged to have one leg thereof movable axially and pivotally in bracket 22 secured to end bar to, the other leg thereof being arranged to enter bracket 22 secured to side bar 8. The leg operating in bracket 22 secured to side bar it] is supplied with a suitable enlarged portion at 5 the end thereof whereby said locking member cannot be entirely removed from said bracket.

Referring to Figs. 3 and 4 showing a modified form of carriage or dolly 30, uprights or vertical members 3| have castors 4 secured to the lower angled end 2 thereof, and resilient clamping portions 33 at the upper end thereof joined by intermediate portion 35, to which are rigidly secured each-end of side bars or rail members 36 by rivets 31 or other suitable engaging means. Clamping portions 33 are inwardly bent and faced with a resilient pad or engaging member 38 arranged to clampably support vacuum cleaner I as shown. The clamping portions 33 including the upper end portion'of intermediateporm ently urge pads. 38 into engagement with said unit End or transverse bars or rails lll are formed in two parts or halves 4| and 42, the inner ends of which are pivotally joined by hinges 42, and the outer ends of which. are pivotally joined to side rails 38 and uprights Si by hinges 44. One of said hinges 43 is exterior ofsaid end bar 40 and the other is interior of the opposite similar bar to permit folding or collapsing of the dolly to the dotted position shown in Fig. 4.

The hinge pins of hinges 43 are preferably formed with extensions 45 passing through opening 45 in cleaning-attachment support member 41 supporting stubs 19 for holding cleaning attachments, as 2i, when not in use.

Hasp or looking member 50 is preferably pivoted on extension 45, and the free or hook end thereof is'arranged to enter opening of bracket 52 secured to side rail 36 for locking said dolly 30 in open position. When said dolly is to be collapsed the free end of said latch is removed from bracket 52 and is placed adjacent the inner side of hinge 43 for locking said dolly in the collapsed or folded position, when fully collapsed or folded. As shown in Fig. 4 the dotted position shows the dolly as partially collapsed, the vertical rails 3| engaging cleaning attachment sup-- porting member 41 when said dolly fully collapsed.

Referring to Figs. 1 and 2, when carriage or' dolly l -is to be stored after use, member i3 is raised, the latch l4 being disengaged from locking projection l1 and reengaged with the upper end rail ill, the lower portion of said rail being interlocked between locking projections I5 and I6 therebyholding cleaner attachment member I8 in folded or locked position. Dolly I is now folded to substantially the position shown in Fig. 2, the free leg of the locking member 23 being inserted into bracket 22 on side rail 8 in this manner locking said carriage or dolly in collapsed or folded position. I

Referring to Figs. 3 and 4, when carriage or dolly 30 is to be stored after use, the free end of hasp 50 is removed from opening 5| of bracket 52. The carriage or dolly is then collapsed by pressure on exterior positioned endhinge 43, the end bars 40 acting as a hinge whereby the side bars 36' are moved toward each other as shown in the dotted position, said movement being continued until vertical rails 3| engage the sides of cleaning attachment supporting member 41, whereafter the free end of hasp 50 is inserted between the protruding members 4| and 42 thereby acting to lock said dolly in the collapsed position.

If desired, the cleaning attachment support or member 41 may be removed from the carriage or dolly prior to the collapsing thereof, thereby permitting the placing of the attachments on a shelf or other support independent of said caric'al storage of said carriage or dolly.

Whereas the clamping members or brackets 9 are shown as independently formed of side rails 8, said members may be formed integral with said side bars, being formed by bending the ends of said side bars around rod 2.

Likewise end or transverse bars lll may have the ends thereof formed to surround rods 2 in the same manner as the ends of said modified side 2,177,158 tion, 85 form a resilient unit arranged to reailibars I, however arranged to pivot on said rods 2,

the end bars ll being positioned in a plane above or below said side bars 8.

The vacuum cleaner unit I may be additionally or independently clampably supported on the devices i or 30 by the means of strap members 53 and 54, one end of which is secured at preferably the mid portion'of upper side rails 8 or 38 g and the free ends of which terminate in a buckle or othersuitable attachment 5!.

The apparatus above shown and described shouldbe construed as typical and not as limiting the invention, the scope of which is defined in the appended claims.
