HANDLE MOUNTING FOR BRUSHES.

Application filed December 16, 1926. Serial'No. 155,253.

The present invention relates generally to brushes, such as are commonly used for cleaning floors or walls,`and which type of brushes `are generally provided with handles ofvarious lengths in accordance Vwith the Vparticular use to which the brushis applied. w

i The primary object of the present invention resides in the provision of a novel type of coupling whereby brushes, mops and the like, may be -swivelly mounted upon handles for permitting of the brushy proper to be adjusted relative to the handle. y

A further object of the invention resides in the provision of ,a novel mounting or coupling means between'the brush proper' and handle therefor whereby the angular relation of the handle to the brush may be adjusted, and the position of the longitudinal or major axis of the brush proper adjustedr with respect to the axis of the handle.

A further object of the invention resides in the provision of a novel` type of handle mounting for brushes embodying novel locking features whereby the handle may be ad-l justed and locked at various angles of inclination with the brush proper, and which mounting also permits of the handle to beV rotated about the brush proper and locked at any desired angle for permitting of the brush to be effectively used in close places or locations where it is desirable that the brush properbe disposed with its major axis `at an angle to the axis of the handle.

A still further object of the invention is to provide a handle mounting for brushes which may be economically manufactured from sheet metal, thus providing a mounting which may be applied to brushes without materially increasing of the cost thereof.

Other objects and advantages of the invention will be apparent during the course of the following detailed description, taken in connection with the accompanying drawing forming a part of this specification and in which drawing.

Figure 1 is a side elevation showing the improved mounting or coupling applied to a conventional type of brush.

Figure 2 is a top plan view of the same. Figure 3 is a fragmentary section on line 3,-3 ef Figure 2. Y

Referring tothe drawing 1n detail, and

wherein similar referenee'characters desig-y nate corresponding parts thruout the several views, the letterA may designate a brush or mop'of any suitablelconstruction, and B the improved mounting or coupling for swivel'- l'y connecting of the brush A to the handle C.-

The brush A in the example shown, embodies a head 10 of rectangular shape in plan, and which head serves as a carrier lfor the tufts of bristles V11. The brush A has merely been shown by way of example, one manner lof use for the improvedmounting, and it will be understood that the brush head 10 may serve for the supporting of other elements such as cotton strands or the like and not necessarily serve as a supporting means for bristles such as illustrated.

Referring now to the im roved mounting or coupling B, the same em odies anl attach- .ing cap 12 whereby the handle C maybe rotatably coupled to the brush A,and a. quadrant 14 serving as means whereby the handle C may be adjusted into various angles withk respect to the brushA. v l

Referring particularly know to the Vconstruction of the attachingcap 12, the same is preferably stamped from sheet metal of l,

a suitable vgauge for'providing a bearing ringl5 provided at; its lower edge with radially rprojecting feet v16 which are intendedy to engage fiat upon the upper face of the brush head 10 and be secu'red thereto as by meansof screws or other suitable fastening elements 17. Y Formed inwardly of the bearn ing ring 15, and disposed between the upper and lower` edges thereof, is a pivot plate Y 18 provided with anaxially disposed fianged opening 19.v As will be observed in Figure 3, this pivot plate-18 is formed as an integral part of the bearing ring 15 and provides a circular bearing seat 20 at the upper edge of the attaching cap which is reinforced bya doubling ofthe sheet metal from which the attaching capis formed. Provided in the f pivot plate 18, is an arcuate shaped slot 21 which extends for a distance sli htly more than 180, and which slot is stragi; from the axial center 0f the flanged opening 19. @pene f notches 2Q, the terminally disposed notches forward lower portions of tlieplat preferably being disposed in alignment diai'netrically of lthe pivot plate i8. lt is preferred, but not absolutely essential, that the attachingI cap 12 be mounted uplo'rr. the brush head 10 `with the terminally aligning notches 22 extending parallel with the major of the brush'head as illustrated in Figiues 2 and il, and which Will dispose the arcuate shaped slot 2l to-one side of the longitudinal centcnotI thebrush head. 'v

Referrifng; now. tol the specific' construction of@ the quadrant l `the saine is preferably struck from sheetl metal of a suitable gauge and embodies a bearing plate Qpr'ovided at each longitudinal edge ir/ith .upstanding parallel spaced apart quadrant plates 26. These quadrant plates 26' are adapted to pivotal'ly receive tlireii'ebetweerr, the handle C, the handle being pivotally connected by means ot a suitable transverse bolt 27 extending; thru the V plates Q6 at peint adjacent the handle C maybe flattened as at 28 Wr extends be'tiveei'i the plates 26, and by so having the pivotal connection oil the handle arranged as shoivn', the plates Will not be subje'cted to any Agreat strainy whenl the brush A is beinfginoyed along the floor. Frovided in each oit thequadlrant plates E26, and eX tending concentric with the pivot 27, are aligning arcuate shaped slots 30 provided with inner 'and outer recesses or Vnotches 8l 32 respectively, arranged in staggered relation. thruout the length et the arcuate slots and opening' into'the slots s clearly shown in Figures l and 3. Thel inner notches 3l et one of the' quadrant plates align with similar notches formed in the arcuate slot of the companion plate, While the outer notches 32 alsofalinn with similarly formed notches provided in' the companion quadrant plate By observing` Figures 1 and 3', it will be seen that the bearingy plate 25 is of greater length than the diameterot' the' bearing ring 15, and that the terminal portions ot the bearing plates are intended to seat upon the bearing 20 provided at the upper edgev oi the ring 15.

A catch 35 is provided ,vherebythe anguf lar relation of the handle C niay be adjusted Y with respect to ther brush A.

This catch 35 and which is intended tobe slidablymounted upon the handle C, is'ot T-shape in formation and embodies a shank 36 provided at its for- Wardend with a transversely extending` head 3? the ends of which are intended* to be moved into either the inner or

outer recesses

31 and 32 which open into the arcuate shaped slot 30. The substantially flat shank portion 36 is providedv With a longitudinally extending slot'38 thru which a suitable headed ,fastening ele`- ment 39 may be passed and threaded into the handle C' for' slidably mountingo-t-l'ieeatch` upon the upper face of the handle between the quadrant plates 26'.. The rear end of the catch 35 is preferablyV curled' upivardlyas at l0 for permitting ot the ready sliding of the catch longitudinally along the handle C. rhus it Will be seen that When the catch Sois slid to', a position whereby the ends of the head 37 align `With the arcuate slots 30, that the l-rand'le nia-y be swung about its pivot point 27 for varying` the a "ular relation of the handle with respect to the brush: A; and when' moved tothe ""ed angle, the catch 36 may b-e slid longitiu nally o-' the handle 'for moving,l the head 3?' into locking' engagement TLvith either the inner orl outer recesses or 232 respectively. i' The quadrant lll, is pivotally connected to the attaching` cap lby means of: a pivot bolt which is passedy thru the bearingplate 25 and extendsl loosely vthru the flanged opening 19 of the pivot plate 18. As- Will be observed in Figure 3, this pivot bolt llefis otless diam'- eter than the inner'4 diameter of the flanged opening 1S) Aand which construe-tien has been i'rr'ivided"y tor permitting of slightV tilting l el the quadrant upon the attaching cap.

Rigi/diy secured to the bearingplate 25 to the rear of the pivot bioltl, and extending below the bearingplate, is a; lrey'fl oi special torina-tion, and which key serves foradjusth ably locking the handle @with its airis in various angular positions with respect to the major axis oi the'brush head A. This key e6, and which may be formed of a single con,- stru'ctionpeinbodies an arcuate'shape'd guide plate 48 provided centrally ot' its end with any upwardly extending shank port-ion Y il@ which may be secured to the bearing plate as means of a nut 50. Projectingv troni each side ofthe arcuate shaped' guide plate e8; adjacenty the upper edge thereof, andipreersev ter-

ably arranged atlthe, longitudinal center of the plate, are alignin'v ears 51 which are adapted for lit Ing into the aligning notches 22 for locking the quadrant le at various locations of rotationup'on the attaching cap 12. rfhi's arcuate shaped guide plate e8 is intended to nieve in the arcuate shaped slot 21 and when desiring'A to adjust the position ot the quadrant 145,- the quadrant is sprungupwardly byv means' of' the handle C' as illustrate'd inr Figure 3:5* and which upward seringing of the quadrant Will allow the earsl to nieve tree ot the slot 21 and be guided across the upper face ofthe pivot plate 18 to the desired location whereby upon releasing ofup- Y ivardv pressure on the handle, the ears k51 Will again engage in the desired recess 22y for retaining thev quad-rant and handle in the desired angular position. The sheet 'metal oi vvhich' the sections'lQ andlllare formed', Will permit of this slight relative yielding for moving ofthe' ears v51 out of locking engagement with either of the aligningrecesses'ZQ. When desiring to adjust'the' angular-relelas tion of the handle C to the brush head l0, the catch 35 is first slid longitudinally along the handle sothat the arms of the head 37 align with the arcuate shaped slots 30, and in which position the handle Cmay be readily swung about its pivotQT to the desired'angle and after which the catch 35 may be slid into either of the recesses 3l or 32 for locking the handle in the desired angular position. lVhen desiring to rotate the handle C upon the brush head l0, the pivot bolt 45 will permit of the quadrants lto be tilted so as to lift the ears 5l out of the notches 22 of the slot 2l and thus permitting the handle to be adjusted relative to the brush head for disposing thel longitudinal or major axis of the brush head in the desired adjusted position with respect to the axis of the handle C.

From the foregoingdescription it will be apparent that a novel and efficient vhandle mounting for brushes, mops and the like has been provided, which is oi extremely simple and durable construction, and which. is of' such construction as to permit of the angular I' relation of a. handle to be adj usted into various positions with respect to the brush head, and embodying locking means' whereby the handle is retained in 'either of its various adjusted positions with respect to the brush proper.
