SUCTION-HEAD CONNECTION.
Specification of Letters Patent.
Patented Apr. 20, 1915.
Application filed July 24, 1914. Serial No. 852,886.
To all 4.0710717, it may concern:
Be it known that I, GEORGE BRAND, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Suction-Head Connections, of which the following is a specification.
This invention relates to an improved suction head connection of the hinged or flexible type for vacuum cleaning machines, and has for an object to'provide a connection admitting of the automatic adjustment of the suction head to variations in the surface being cleaned and to the movements of thebody of the machine; and a connection which limits the swinging of the suction head to maintain it in proper position on the machine at all times.
Another object of theinvention is to provide a connection of this character admitting of the substitution of a flexible hose or tube in lieu of the suction'head to thus adapt the connection to vacuum cleaning. machines wherein hand tools are employed.
The above and other objects and advantages of brought out from the following detail description of the present preferred embodiment of this invention which is illustrated in the accompanying drawing wherein,
Figure 1 is a side elevation ofthe forward end of a vacuum cleaning machine having the improved nozzle connection applied thereto. Fig. 2 is a top plan View of the same with the bellows removed. Fig.3
is a central. vertical section taken through the connection. Fig. 4 isa detail inner end view of the shank ofthe tool comprising one member of the connection. Fig. 5 is a top plan view of the tool support disclosing a flexible hose or tube applied thereto.
Referring to this drawing, wherein like parts are designated .bysimilar characters of reference throughout the severalfviews, 10 designates the body of a vacuum cleaning machine of anysuitable type, provided upon its upper side with an operating bellowsll. A dusttube 121 is 1 arranged beneath the body 10 and projects forwardly therefrom, the forward end of the tube 12 being open and curved upwardly as shown at13 in Figs. 1 and 3. The body 10 is prothis invention will be more clearly vided at its opposite sides with'a pair of brackets 14, the outer ends of which carry transversely, alining bearings 15 receiving therethrough an axle 16. Wheels 17 are mounted upon the opposite ends'of the axle 16 to support the forward end of the body 10 and have suitable connection, as by means of a pitman connection 18, with the bellows 11 to operate the latter.
7 Hinged upon the axle 16 between the brackets 14; is a head support 19 preferably of yoke-form, the opposite arms thereof having therein bearings 20 engaging the axle 16. The bearings 15 of the brackets are provided at one side with stop shoulders 21 lying in the path ofabutment shoulders 22 carried upon the bearings'20 ofthe the abutment shoulders 22 for the purpose of limiting the upward swinging of the support 19. A suitable" suction head 24: is employedwhich is provided at its inner end with laterally extending lugs 25 through which pass thumb screws 26 for engagement in the support 19.
From Fig. 2, it will be noted that the lugs 25 incline inwardly toward the body 10 aka slight angle and lie snug against the correspondingly formed outer face of the support 19. The support 19 is provided, as shown in Fig. 3, with a through port 27 communicating with the suction head 24. The support 19] comprises, practically, a continuation or a part of the suction .head and is provided with a downwardly and rearwardly curved shank 28 telescoping into the forward. open end 13 of the dust pipe.
i may -be-"mo'ved freely one within the other.
without binding. From- Figs 3 and 4 it will be noted that the shank 28 is provided upon its open end with a packing ring 29 clamped against the end by a metallic clamping ring 30. The clamping ring 30 is suitably held against the open end of the shank 28 by screws 31 or the like, the screws passing through the packing ring 29 and into the walls of the shank 28. The packing ring 29 and the clamping ring 30 are provided with central openings corresponding in size to the opening of the shank 28 to thus prevent any restricted. portions or dustcollecting shoulders within the connection? In Fig. 5 the tool 24 is replaced by a nip- 'ple 24, the same being held against the support 19 by the thumb screws 26. The nipple 24 is adapted to receive the inner end of a flexible pipe or tube 32 tached a hand tool (not manner.
In operation the body is supported upon the wheels 17 and is moved forwardly in any convenient manner. The wheels turn and operate the bellows 11 to create a suction through the body 10 and dust tube 12. The suction head 24 rests against the surface to be cleaned and is held thereagainst by its own weight, the head 24 swinging about the axle 16 as a pivotal support. As the shank 28 and the curved end 30 are concentric with the axle 16 the connection admits of the free swinging movement of the head to take up unevenness in the surface cleansed, or vibrashown) in the usual tions of the body during the operation of the machine. The packing 29 carried by the shank 28 bears against the inner wall of the curved end'l3 and thus effectually seals the connection so that the suction through the head 24 is not destroyed.
By constructing the suction head so that it may swing about a horizontal axis and by having the shank on the support and the end of the dust tube both concentric With theaxis free movement of the various parts is provided and by providing the telescopmg parts with the packing an effective seal is formed which does away with all flexible couplings wherein tubes and the like have heretofore been employed.
It is, of course, understood that various minor changes may be made in the details of the structure Without departin from the spirit of the invention and With n the scope 'of the following claims.
