Application July 1931. Serial mfssasss lClaim. (c1. 306-30) This invention relates to attachments for interchangeable handles for brooms, brushes and the like, and particularly relates to a type of such attachments whereby the handles of push brooms land the like may have eliminated therefrom the usual thread on the connecting end which attaches to the block of a broom.
While the invention is described herein with relation to push brooms, it is to be understood Ias adaptable for use with mops, wall cleaning brushes, window cleaning devices and the like.
Heretofore it has been customary to manufacture handles for devices of the kinds above mentioned and provide at the end thereof which is 15" to be connected to the broom or mop, a threaded portion which is adapted to be engaged in a threaded recess in a broom block. These handles are made of both hard and soft wood, and in the case of soft wood, the cutting of the thread Ireduces transversely the size of the handle so that there is the likelihood of breaking of the threaded shank from the handle, and also likelihood of breakage in the handle from its normal use or from being stepped on by the operator. In the case of hard wood handles, it isdiflicult to cut the thread, the threaded shank is liable to break at point of connection with the handle, and in both the hard wood and soft wood handles, the threads of the shank chip off due to the fact that they run with the grain of the wood and the threads have no lateral support.
By providing an attachment for connecting,
handles to broom blocks in which the threaded shank is rigid metal, and a tubular sleeve is provided of resilient material, the thread of the wooden handle may be entirely eliminated and handle members of varying transverse dimensions may be used, and the handles may be made interchangeable, thus accomplishing a saving in the cost of cutting threads on the handle, and also making the handles interchangeable in case of breakage. I
Objects of the invention are to provide an attachment for connecting push broom handles to a broom block and wherein the handle may be interchangeable; to provide such an attachment whereby the usual threaded portion of a push broom handle may be eliminated; to provide such an attachment having a resilient portion to engage the handle and a rigid portion to engage the push broom block; to provide such an attachment in an integral structure wherein one portion is resilient and another portion rigid.
With the above mentioned and other objects in view, the invention consists in the novel construction and 'combinationof parts hereinafter described, illustrate'd'in the accompanying drawing and pointed out. in the claim hereto ap- I pended; it being understood that variouschanges in the form, proportion, size and minor details of construction within the scope of the claim may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention. I
To more clearly comprehend the invention, reference is directed to the accompanying drawing', wherein- Fig. 1 is an end view of push broom with handle I therein, showing position of handle attachment of arrow i 10 represents generally a push broom having a broom block 11 provided with bristles l2 and having connected thereto an elongated handle 13.
An elongated tubular sleeve member generally indicated 14 is provided, which is adapted slidably to receive through an open end l4: one end portion of the broom handle 13, the opposite end of the sleeve being flanged radially inwardly upon itself, providing a shoulder 14 which has anelongated extension or shank 16 which is preferably tubular and is provided with a helical thread 16 It is preferred that the sleeve and threaded shank be formed of an integral sheet of spring metal such as sheet steel of about 20 gauge, which is readily obtainable in the commercial market.
The main body portion 14 of the tubular sleeve is preferably arcuate in lateral transverse cross section, providing substantially parallelly spaced edges 17 and 18, each of said edges being provided with means whereby the transverse cross sectional diameter of the sleeve portion 14 may be contracted, said means as exemplified consisting of outwardly turned lugs or ears 20 and21, which, in Fig. 3, are shown as beingtwo on each of the edges 1 7-18, and on each edge.
The ears 2021 have openings 20 and 21 in Fig. 7 as one elongated ear through which are received headed bolts 22. 23, 3 1 0 material having a degree of resiliency, as above stated, it is apparent that the sleeve portion 14 will have a degree of resiliency in its arcuate= form so that when a broom handle isplaced therein and the bolts tightened, the 'h'and-le will. ,bev
securely held therein, and so that the handle may be removed by loosening theboltsa:
Because of the shoulder 14' being flanged ra:-
dially inwardly from the wall of sleeve 14,..it is obvious that there will be subs'tantiallyno resil ience at the flanged end but that the-resiliency will increase by degrees in the direction of the open end 14 The' corrugationsrforrn'ed by the threadslG of shank 16 willlreinforce the walls of the shank to an extent that radial resiliency of the shank will be completely negatived, and'a tight abutment will be formed by the parallel abutting opposing edges 27, 28 of the shank wall. Having thus described our invention, what we claim and desire to secure by Letters Patent is:-
vA device of the character described comprising en elongated: tubular longitudinally 5 split 7 sleeve open at one end and flanged radially inwardly at the opposite end providing a circumferential shoulder, a rigid externally threaded hollow cy lindrical shank extended from saiolflanged shoulderportion-and of lesser lateral transverse diameterthan the tubular sleeve, and said sleeve including means: whereby the sleeve may be releas- -ably-;;clamped about an implement handle, said sleeve and threaded end portion being of substantially uniform'thickness of material whereby said i device maybe formed from sheet metal,
