Claims. (Cl. 16—115)

This application is a division of our copcnding application Ser. No. 116,123 filed June 15, 1926 from which has matured Patent No. 1,757 239 granted May 6, 1930.

Our invention relates to the art of carrying devices and more particularly to the carrying of certain articles such as vacuum cleaner units comprising separable parts.

m -J¹¹® ^{principal object of} invention is to prow vide a detachable carrying device which is convenient in use, neat in appearance, durable, readily manufactured and which fits snugly to the body to be carried when not in use.

Further objects and the nature of our invention be apparent as the description proceeds. The description is of one preferred form but it is to be understood that it is not intended that the invention be limited to the form described, .deferring to the accompanying drawings which 20 illustrate the preferred form of our carrying device: Fig. 1 is a side view of the main unit, of a suction cleaner; Fig,. 2 is a longitudinal section of the so-called main unit; Fig. 3 is a section on line ^{3—3 01} 1, with internal parts of the unit omitted; Fig. 4 is partly a plan view and partly a sectional view of a carrying device embodying the invention for carrying the main unit; Fig. 5 is a section on line 5—5, Fig. 4; Fig. 6 shows a pin normally arranged at one end of the carrying deW vice; Fig. 7 shows a spring member also forming part of the carrying arrangement; and Fig. 8 shows the cleaner in operation.

The main unit of the cleaner, shown in side view in Fig. 1 and section in Fig. 2, comprises a casing 95 Jn turn comprising a main cylindrical barrel 10 consisting of stiff material or leather composition having attached thereto at one end a metal bell 11, and, at the other end, a metal housing 12. Bell 11 is removably secured to barrel 10 by means 10 of suitable spring clamps 29 secured to the barrel and engaging a shoulder 35 on the bell. Housing 12 contains the electric motor 13 and the fan 14. Forward of housing 12, that is, in direction toward bell 11, is a disinfecting air filter 15 and 5 forward of the filter 15 is the dust bag 16. The forward end of the dust bag consists of a flanged metal ring 17, around the flange of which is placed a rubber washer 18. The flange of ring 17 and the rubber washer 18 are clamped between 0 bell 11 and the flange 19 of a circular ring 20 attached to the forward end of the main barrel by means of rivets 21 and forming part of the main barrel.

A central coupling 23 is screw-threaded into a ’ central opening 8 in bell 11 by means of threads and has a central tapered passageway 25 into । ^h’_M^{m no}??^al operation, the tapered end of a flexible metal air hose 26 is jammed, which air hose leads to the mouthpiece 22 into which the dust passes, an extension 9 (Fig. 8) being used be- 60 tween the mouthpiece and the air hose if desired. Coupling 23 is readily removable from bell 11 by mere turning of the hand and for this purpose is supplied with a roughened surface in the form of ribs 27 to provide an easy grasp. eg

In normal operation air containing dust passes in through passageway 25 from tube 26 and mouthpiece 22 and into dust bag 16 where the dust is deposited, and from which the air after Passing through the cloth of the dust bag, passes 70 through the filter 15, thence through fan 14, and tout to the atmosphere through the opening 28 at the rear end of housing 12. Opening 8 may be considered as the air inlet and opening 28 as the air outlet for the unit. »

In order that the motor-fan unit· may be readily detached from the barrel it is secured to the barrel by means of screws 41 which are accessible and removable from outside the main cleaner unit as a whole. A ring 42 is fastened to the rear 80 end of the main barrel by means of rivets 43 The motor-fan housing 12 is machined to fit within ring 42 and the barrel. The screws 41 pass through ring .42, through the barrel, and thread into the motor-fan housing. By merely sr removing screws 41 and detaching the strap 65 by a simple manipulation, which will be presently described, the unitary housing 12 may be de• ri? f^rom the main barrel, thereby separating those parts which may be termed active from those parts which may be termed inactive, without interference with electric connections nor mountings nor mouthpiece connections, and without any mechanical dismantling, nor necessitating the services of a mechanic

Housing 12 is made of two parts 12α and 12&amp; which may be secured in any desired manner, but preferably so that they may be readily separated. *

The main barrel 10 and associated parts are mounted upon runners 60, of which there are two one positioned on either side of the main barrel’ and which form a sled carriage for the main unit. The runners are fastened at each end of the main barrel to clamps 61.

In order to carry the main cleaner unit comprising the main barrel 10 and attached parts a strap 65 Is provided. This strap consists of a central flat steel spring 66 which is surrounded by cloth or leather or other suitable material 67

4. A handle comprising a strap, a first stand- 10o ard having slots therein, a pin mounted in said standard and movable in said slots, said strap (see Figs. 4 and 5). The strap at one end surrounds a pivot pin 68 which is mounted m a standard or strap-holding member 70. Standard 70 Is attached to the housing 12. Between the s strap 65 and pin 68 there is a metal member 71 (Fig. 7) of yieldable nature. Pin 68 has a central portion 72 over which metal member 71.fits and two end portions 73 of greater diameter than the central portion 72 and of greater diameter io than the unsprung natural internal diameter of metal member 71. Portions 73 fit into openings 74 in standard 70. Pin 68 is provided with bevelled portions 75 which normally are adjacent the ends of metal member 71. Pin 68 in normal

The purpose of the arrangement just now described is to allow by very simple means, a quick release oi strap 65 from standard 70 so that the motor-fan •0 housing 12 to which standard 70 is attached can tions 73 slip mside memoer &lt;i. v _fee having bevelled portions between toe outer is a™ made laree enough to afford clearance for the pin and said resilient member, are made large enougn been moved * ⁴ nnmnrismc a str

Obviously different arrangements of parts may be used and parts may be modifiedwitooutdeparttag from the sphere or scope of the invention. The invention is not to be limited to the detailed description of the specification which has been drawn with a view of setting out one example completely to enable those skilled m the art to readily make and use the invention, but is to be limited merely by the state of tne prior art and the scope of the appended claims.
