An object of the invention resides in the novel manner of shaping and constructing fitting connection witha handle unit and a removable sleeve.

- A feature of the invention resides in the form of interconnection between the casing members, the brake-mechanism, the reel unit, the sleeve and the handle unit which enables by a simple operation the interconnection of the brake mechanism with one'of the housing members, the quick placement of the reel 5 unit in position with the brake mechanism,

the quick interconnection of the casing members and the locking of the casing members in position by the forcing of the handle unit and the sleeves into attaching connection 3 with the casing members.

Another featureof the invention resides in the providing of the casing members with companion flanges and neck sections so that the membersmay be readily forced into interlocking engagement with each other and held in such engagement by' a sleeve and tubular handle unit which are slipped over the neck sections which not only establishes a rigid connection between the sleeve, handle unit, and the casing members but positively locks the latterefrom moving in..a directionthat would disconnect the same.

Besides the above my invention is distinguished inthe formation of the: component parts of metal stampings that ,are s'odesigned they are capable of being connected to each other by a chain system of production.-

With these and other objects in View the invention will be better understood from the' following detailed description taken in connection with the accompanying drawings wherein--' Y i Figure 1 is a plan view of the handle structure.

Figure 2 is a I Figure 3 is a side elevation partially disconnected.

Figure 4 is a perspective view of one of the casing members;

- Figure 5 is a cross sectional view of a (for- 50 7 tion of the casing members disconnecte Figure 6 is an enlarged detailed sectionalview through the bearing and associated parts. I

Again referring to the drawings illustrating one of the many constructions of my invention, the numerals 1 and 2 designate the companion members of the'casing 3 of the handle structure. In the particular showing the members are illustrated as metal stampings which enablsthe production of the members at a low cost. In'the stamping of the members the bodies4' are provided as well as the neck sections 5, there being companion flanges 6 .formed along the abutting edge portions of the bodies so that thebodie's may be brought into interlocking connec-' tion with each other. In a particular showing one of the -flanges 6 is oifset from the 30 body 4 whereas the other flange is in align- 'ment with the, body 4 so that when the bodies are brought together the casing '3 will have a smooth exterior surface. One of the neck sections is minus flanges so that the edge 35 portion 7 may be brought into flat abutting relation with each other to eliminate projec tions interiorly of the neck. The member 1 in the stamping thereof is formed with a depression 8 and a hole 9 centrally of the depression for the reception of a bearlng 10. I I

This bearing 10.is further provided with a plate 11 received within the depression 8 and further provided with a hub- 12 passed 3 through the hole 9 so as to occupy, aposition l of the casing. This bearing 10 may I interiorlg be locke in position inany desired manner such as by spot weldingor insertable fasteningdevices so as to secure the same in position 1 longitudinalsectional View. 55

' '9 inated from thlsspecification a detailed idein conjunction with the parts of a brake mechanism hereinafter described.

The brake mechanism illustrated is practically identical with that shown in the above 5 mentioned co-pending application with the exception that the'bearing ring 14 is directly secured to the plate 11 through the wall of the casing by means of the screws 15. The brake ring 16 that is movably mounted on the bearing ring 14 is provided with recesses 17 with which interconnects the lugs 18 projecting from. the reel unit 19. Thisreel ,unlted designed along the lines of the unit shown in my above mentioned copend-ing application is mounted on an axle 20 that is secured to the hub 12.

A screw 21 passing through the casing member and engaging the end of the axle 20 not only supports the axle but provides a rigid connection between the casing members at a central point.

As far as I have proceeded it will be appreciated that the bearing may be readily slipped into place and the brake assembled on 12 and brought into interlocking engagement with the brake ring 16 through the disposing of the lugs 18 within the recesses 17. After this has beenacc'omplished the inserting of the screw 21 provides a-second bearing support for-the axle and besides draws the component parts together with the flanges of the casing members in proper-interlocking conncctionj .For the purpose of providing a more rigid connection for the casing members, and also decrease the cost of assemblage operation, I provide a rigid connection between the handle proper and the casing and between the casing and a socket structure and to accomplish this I take advantage of the arrangement of and the abutting relation provided between the .neck sections.

, The handle unit 22 is formedfrom a tube and provided with a 'hand grip .23 with the outerend portion closed by the lug 24. The inner end portion of the .han le 1s slipped over and has a snug fit with a set of the companion neck sections 5 thereby locking the neck sections together and the handle inengagement with the casing. To provide a more positive connection, the handle as well as the neck sections may be upset at the point 25 or ihe handle may be spot welded to the neck sec- Theremaini'ng set of neck sections are positively held in abutting .relationfwith each other by interengagement therewith of the sleeve 26101311111 one of the members of the socket unit 29. 7 he neck sections 5 that I associated with the sleeve 26 are formed with a head 28 which provides an abutment for the socket 29 when the same is forced into place. For the pur' use of clarity I have elimthe hub and the reel unit slipped on to the hub tities of the component parts may be assembled at various points in an assemblage lane. That is to say, a group of the casing members 1 may be arranged at the start of. the production system, arranging in a progressive line groups of associated parts terminating with a group of sockets 29. It will be appreciated it is a Very simple operation to assemble the various parts due to the fact thatthe bearing 10 maybe very quickly'slipped into position within the depression 8 and locked in said position by the screws 15 that secure the hearing ring 14. The brake ring 16 can be very easily mounted upon the bearing ring and then the axle 20 may be secured to the hub 12. A further step in the assembling operation relates to slipping onto the hubl2, the reel unit 19, bringing the lugs 18 thereof into 1 interlocking connection with the recesses 17 inthe brake ring for providing a positive connection between the brake ring and the f reel unit. As a next step in the assemblage of the parts the casing unit 2 is forced into interfitting connection with the casing unit 1 through the interrelation of the flanges 6; When this has been accomplished the screw 21 is in mounted position which looks the heretofore described parts in assemblage relation.

As a final operation the handle unit 22 is slipped onto the neck sections and locked thereto by upsetting atthe point 25. Sleeve 26 is then forced onto the remaining set of 1 neck sections and the socket 29 forcedinto position in abutting relation with the bead 28.

It will now be apparent that I provide a very substantial type of handle structure for vacuum cleaners mcorporating an automatic cord take-up device in which the various parts are so designed that they may be economically produced and assembled at a minimum cost. Of course it is to be understood that'the de sign of the component parts may be changed and the mode of assemblage ma be varied without departing from the spirlt of the invention and therefore I do not desire to be limited in protection in any manner whatsoever except as set forth in the following '1 claims.
