Serial no. s42,ee2.

This invention relates to' suction cleaner tools, both'of the ordinary, as Welles of the air-way type.

- The objects of theinvention are to'p'rovide I a lint-removing or thread-picking attachment to such tools, to provide such tools w th an automatico'penlng and closing means for the ends operating. intermittently, and to produce vibration in such tools, and to produce other novel results as may appear in this specification and claims.

To these ends, the inventlon may conslst of a construction, arrangement and comb nation of parts as set forth and illustrated in the accompanying drawing, in which,

Fig. 1 shows a longitudinal crosssectlon of the cross-head-of a suction tool, to which the floor tool is pushed bac and forth over -ny improvements are attached;

Fig. 2 is an under-side or bottom view of such cross-head with said attachi'nents;

' Fig. 3 is an end view taken at right angles;

to that of Figs. 1 or 2, particularly portraying the improved form of rubber-capped roller'to he e'mbodied in the invention, and.

75 V Fig. 4 is a View partially in cross section through the middle of the cross-head with the threadpicking attachment inserted.- Referringto the drawings, the cross-head 1 having the open interior 2 communicating pieces 4 and l having lower edges fcoplanar and adapted to contact with the surface-or carpet 5 to be cleaned.

At each end of the body 1 is a roller '6 mounted in a shank 7 having a spring 8 adapted'to al1ow.of a yielding vertical mo;

tion of the mounted roller, and the shanks also carry end lids 9, 9 secured to the shanks I at 10, 10, whereby vertical movement of the from the end openings 9, 9' between-the ends .of the coplanar lips of the pieces 4, 4'. The rollers used in thiscase are special; they are preferably constructed of resilient rubher and have a series of frets or projections 6, 6', 6", etc.,= on their peri heries. These frets are designed to cause vi ration upward and downward of the lids 9, 9,. or of the tool itself, or both, as modified by certain circlunstnnces hereafter referred to.

with the suction pipe 3v is provided with. lip

roller in one'dijrection will remove the lids" Besides the roller attachments referred to,

the interior of this floor tool may be provided with a thread-picking device constructed preferably from resilient wire 11,

recurved as at 11,- and having its ends 12,

12 pivoted at the top of the interior of the tool; The lower part of this wire,' which is coplanar with the lips of the tool, is provided with a cushion 13, preferably constructed from rubber tubing slipped over the wire. The thread picking element-may side arms of the wire .11, thus drawing its ends 12 out of their sockets. i

In the operation of the device, the threadpicking device is alternately"pressed against the coplanar parts of the li pieces 4, 4', as

be understood-that if the body of the tool is pressed downso that vthe lips are pressed flat against the'surface to be cleaned, then the frets-6', 6,j- 6' etc. will cause the lids to be lifted intermittently, as the rollers travel with a Jumping motion. If, however, the

vbe removed by simply pressing inwardly the operator presses only lightly downwardly on tool'the bodyxof the tool will be found to vibrate slightly with reference to the floor. i

Having; thus described a preferred con- 'stru ction and mode of operation of the device, this specification is not intended to be restricted to the exact constructions shown, as many modifications ma be employed within the scope of the appen ed claims. I

I claim: j

1. In a floor tool having floor engaging lips and having tool end opening and closing means, means for operating said opening and closing means, a swingin element within the body of the tool, and having a cushioned portion thereof coplanar with the lips of the tool and adapted to impinge against the in-' terilor of either lip in the operation 'fof the 2. In combination with a pneumatic clean- 5 ing tool having end openings, end rollers 'for' said tool, roller shanks resiliently mounted in theends of said tool for supporting the tool on the rollers, lids for said end openings carried by said shanks, and peripheral projections on said rollers adapted to cause vertical movement of the lids during the operation of the tool, for intermittently opening and closing said end openings, and a thread picking element swingingly mounted within '5 and adapted to engage a portion of the mouth of thetool.

3. In a floor tool having floor engaging lips, and having end openings, means'for automatically and intermittently opening and closing said end openings during operation of the tool, and .a swinging .elemen't pivoted within the body of the tool, said element having a thread picking portion substantially coplanar with the lips of the tool 5 andlswingable from side to side to contact with one or the other of said lips.

4. A floor tool having floor enga ing lips and having-end openings, means or automati'cally opening and closing, 'said end openso ings onmoving said tool over a surfaceto be H cleaned, and means swingingly mounted within the body of the tool and coacting with the H s of the tool for grasping threads or;

thelie.- 3'5 5. A floor cleaning tool having floor engaging lips and having end openings,means forautomatically opening and closing said end openings on moving said tool over a surface to be cleaned,.in combination with means .0 coacting with the lips of the tool for grasping, free threads or the like on the article to be cleaned, said thread, grasping means comprisingban elementswinging y mounted with- I in the ody of: the tool so asto contact with .one or the other lip of'the tool.

y 6. In a cleaning tool, a thread picking ele-v, ment consistingof a movablebar arranged within the mouth of the tool, adaptedto be pressed against a lip thereof so as. to grasp no threads anddhe like betweensaid bar and lip, and"meansxfor'detachably ,supportin said bar'withinthe body of the tool, sai

means comprising resilient curved arms ex-- tending 'w'ardlyv from the movable bar, said at arms beih g bent outwardly at their upper, portions, said-outwardly bent portions being yieldingly engaged within. the body of the In testimon whereof I aflix si ature. DAN IIL BENSON RE LO LE.
