PNEUMATIC CLEANING-TOOL.

Specification 51 Letters Patent.

Patented March 24, 1908.

Application filed April 8, 1907. Serial No. 366,954.

To all whom it may concern:

Beit known'tha't'I, CHARLES MOUKOS, a citizen of the United-States, and residing at Milwaukee,-in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Pneumatic Cleaning-Tools, of which the following is a specification, reference being had to the accom anying drawing, forming apart thereof. y invention relates to improvements in pneumatic cleaning tools and more especially to the class of handles adapted for use with tools employing air as a cleaning agency in roper. The'objects of my invention are to provide an improvement in means whereby a tool handle when attached to the tool may be adapted to turn to any desired position out of t e normal, should it be desired to use the tool for sweeping in places difficult to reach -when the handle is held in the ordinary sweeping-position and at the same time provide an air tight joint between the handle and tool that will preserve a clear unobstructed air passage there between in all positions of the handle.

Other objects and novel features of construction will be pointed out and described in the specification following and are illustrated in'the drawing. accompanying and forming a part of said specification wherein my improved means for connecting a tool and tool handle are shown in connection with a pneumatic cleaning brush.

elevation of t e device showing the clamping member in section and-the external appearance of the joint; and Fig. 3 is a deta1l view showing the structure of the clamping member.

In the drawing, a brush 1 of a constructron common to pneumatic cleaning brushes is provided with a skirt or casing 2, which is i bet of the member 1 Integral with the late 5 and curving upwardly and outward y therefrom is a barrel 7 provided with a bore 7 which latter is largest towards the outer end of the member 7 and is contracted adjacent to the nozzle 4 so that the internal bore 4 of the nozzle 4 and the bore 7 of the member 7 form a continuous passageway, the faces of each of the members 4 and 7 lying flush with each other and offering no protruding parts that may collect dust or interfere with the free passage of the air through the channel or bore in said member.

At the outer end of the member 7 is formed an annular rim 8, this being preferably formed integral with the member 7. The rim or flange 8 is rovided with a beveled exterior face 9 whic 1 slopes rearwardly from the outer face of the member 7 toward the main body thereof. This rim or flange 8 is further provided with a rabbet 9 which forms a seat in the outer face of the member ,7, the purpose of which will hereinafter be more specifically set forth. To cooperate with the member 7 and the flange 8 above described, there is provided a barrel 12 which is similarly to the member 7 provided with a rim or flange 13 having a beveled face 13'.

This flange 13 is further provided with a projecting face or shoulder 14. The object of this projecting face 14 is to seat within the rabbet 9 of the member 7 when the parts are secured in operative position.

It is to be noted that when the parts are brought together in o erative relation that the projecting rim or s oulder formed on the outer face of the member 12 seats in the rabin such a manner as to form a flush joint. The projecting portion 19 of the member 7 forms a bearing face which rests against the recessed 'portion of the member 12, the interior faces of each of these portions lying flush with each other and preferably of a ilexiblematerial impervious not in any way obstructing the bore of the to the air, secured to a body 3 through which 5 barrel thus forming practically an air tight extends a nozzle 4 provided with a borc 4. joint and also one oflermg no obstruction to Set u on the up er face of the body portion the free passage of air and of dustand dirt 3 of t e brush 1 1s a plate 5 which preferably 1 through the bore of the brush handle.

iscircular in formatlon and is secured in the present instance b means of screws 6.

' It is to be on erstood that the plate 5 maybe secured inany suitable manner to the chan e in the osition ofthe barrel or handle 17 w on is a apted to enter the member 12 within the recessed portion 18 of said member 12. This handle 17 is so disposed the member 12 as to have its bore in aimement with the bore of the member 12, the interior face of said member 17 lying flush with the interior unrecessed face of the member 12.

By a rotation of the handle 17 in either direction from its position in Fig. 2, and consequently the member 12, the former can be made to assume various positions intermediate the normal sweeping position illustrated in Fig. 2, and the horizontal position shown in Fig. 1, for cleaningunder furniture and other places not readily accessible with a handle disposed relative to the tool body, as

. the screw 11.

seen'in Fig. 2.

In order to secure the brush handle to the member 7', the member 12 is adapted to be clamped to the member 7 by means of a tightening the screw 11 the clamping ring 10 more firmly secures the members 7 and 12 in locked position and similarly by loosening the screw 11 these members may be permitted a freer rotation or entirely removing the clamping ring the members may be separated. l

The ring 10 is normally loosely clamped about the meeting faces of the'members 7 and 12, so that while insuring an air tight 'oint, it does not cause too eat a friction etween the parts, but permits an easy and free movement therebetween.

For the purpose of securing the barrel or handle 17 within the member 12 there are provided 111 s 15, 15 upon the outer surface of the mem% drawn together by means of the thumb screw 16. This clamping member consisting of the lugs 15, 15 and thethumb screw 16 secures the member 17 in locked engagement within the member 12 and should it be desired to remove this member 17 the clamping member'just described is loosened to permit ofthe easy removal of the member 17 The oper'aLion of the device herein de-- scribed is readily apparent from the foregoing descri tion but may be summed up briefl as ollows. When the parts are as semb ed member 12 through means of its projecting rim13, seats within the recess 9 of the member 7 with its bearing face 20 resting upon the bearing face 19 of the member 7.

er 12 which are adapted to be p The clamping ring is then placed in oper-' 'ative position and is tightened to secure together, and at the same 'time permit a free -movement of the parts,.the handle 17 and the member 12, the handle being ordinarily at the normal angle convenient for sweeping as shown in Fig. '2'. When it is desired to sweep in places not readily accessible-in the normal position of the handle, the handle together with member 12 is turned until such a position or angle is reached as will enable the o erator to readily sweep the portion of the cor desired. After sweeping this portion of the floor it is of course understood that the handle. is turned back to its norinal position, this being done without the operator being bothered with any ad'ustments of screws, clamping means or ot er parts. These adjustments in the position of the handle are accomplished by the movement .of'the op'erators arm in sweeping, and take place as often as the need arises in the course of operation'of the tool; In the actual use of the tool, the clamping ring is normally ad justed to permit of an easy and free movement between the two barrels. This freedom of movement allows the handle to be rotated was to assume various positions between the normal sweeping position of Fig. 2 and that shown in Fig. 1, in harmony with the movements'of the operators arm, and

without interruption of. the operation of swee ing, for the purpose of adjusting the han e. Owing to the angular relation of the meeting faces of the two barrels, the handle receives upon rotation two adjustments relative to the brush, that of its vertical angle and also that of its horizontal angle thereto, so that beside taking any desired vertical position, it'is turned to one side or the other to take u any desired horizontal I an 1e with the brus The handle is thus se -adjustin in actual use, to the movement of the arm 0 the operator, and freely adapts itself to. the various changes in position neces-. sarily assumed by the. operators arm in sweeping beneath and around sundry articles of furniture and other objects.

The special structure'of the joint which permits of the accomplishment of the objects herein-before set forth has been described and the operation of the brush handle provided with this special construction of joint fully set forth. It is understood that only the preferable form of this joint constituting my present invention has been described and that various modificationsmay be introduced into details thereof without in the least departing from the spirit and member having its end face cut away at an oblique angle, and provided with an annular rim, a rotatable barrel having its end face cut at an oblique angle and provided with an annular rim, said barrel being mounted for rotation upon the tubular memher, the annular rims and angular end faces of the parts interfittingj and adjustable means for securing these parts in operative position and to permit rotation of the barrel about the tubular member, substantially as described.

2. In a pneumatic cleaning tool of the character described, a tubular member having its end'iace out at an oblique angle, an annular rim formed thereon and provided with a rabbet, said rim being provided with a projecting portion, a rotatable barrel having its end face cut at an obli ue angle and provided with an annular rim iaving a projecting portion and a recess, said projecting portion of the rim being adapted to seat within the rabbet of the tubular member when the parts are brought into operative clamping means for securing thebarrel upon the tubular member, said clamping means permitting the free rotation of the tubular member, and a tubular handle mounted within said barrel.

4. The combination, in apneumatic cleaning tool, oi a tubular member, a barrel rotatably mounted upon said tubular member, the end faces of the tubular member and barrel being cut away at oblique angles and contacting, and adjustable clamping means for holding said barrel in rotative relation to the tubular member, and permitting the horizontal and vertical angular adjustment of the barrel with respect to the tubular member, substantially as described.

5. In a pneumatic cleaning tool, a tubular supporting member mounted upon the tool. an annular rim disposed at the outer end 01 said supporting member, said rim being provided with a bearing face and a rabbet, a barrel provided with a rim coi'iperating with the rim of the supporting member and seat ing within the rabbet thereof and against the bearing face of said supporting member rim, and means for loosely clamping said barrel and supporting member in operative relation, to permit free rotation of said barrel.

In witness whereof I hereto afiix my signature in presence of two witnesses.

CHARLES MOUKOS.
