ELECTRICAL ATTACHMENT. ron spoon TOOLS OR NOZZIiES OF AIR-METHOD CLEANERS Daniel Benson Replogle, Berkeley, Calif., assignor _ to The Ohio Citizens Trust Company, Toledo. Ohio, a corporation of Ohio, as trustee > Application June 7, 1928, Serial. No. 283,585 8 Claims. This invention relates to cleaning tools adapted. (Ci. 15-43) but ‘being. su?lciently resilient to permit sufficient to be used in connection with pneumatic. or small vertical vibrations of the stroker I”. , suction cleaners which are electrically driven, The vibrations are‘ produced by the electro magnetic buzzer in the encasements 8, 8, carrying and more particularly in connection with air ’5 method cleaners known commercially under the registered trade-mark “Air-Way". ‘The inven a common plate or vibrator‘ arm 5, screwed to a the encasement walls at 9, 9, etc. . Either type, tion relates more in detail to attachments for vthe current breaker, or the alternating current type buzzer can be used, but the one here shown is an alternating current type buzzer in which the armature strain is regulated by the extension 10 “Air-Way" cleaning tools of the type described in my application for Letters Patent Serial No. 10 15,529, ?led March 14, 1925. , The objects of the invention are to provide an electrically operated attachment to be connected to the ?oor tool and operated by an electrical ex tension cord from the motor, to improve the ac- ' 15 tion of the floor tool by vibrating a portion of the face of the tool, to make and combine an electrical buzzer with such ?oor tool when op erated on stationary plants; and other objects as may appear from this speci?cation and may be 20 pointed out in the claims. ‘ To these ends, the invention consists of the-de sign, construction and arrangement of parts and elements as shall ‘now be described and as are illustrated in the drawing, in which: 26 Figure 1 is a plan view with sections taken on the lines C——D and E-F of Figure 3. ' Figure 2 is a reduced size view in perspective of one end of the buzzer attachment; a similar end being broken away. 30 - Figure 3 shows a section taken on the line A-B of Figure 1.' ‘ Figure 4 is a. greatly reduced viewin perspec- ‘ springs l0, l0, which springs are to be varied in tension by the knurled nuts H, H, according to the power and current applied through the coils l2, I2, etc. which may be’ wound to work in series or in parallel, but are‘ here shown as in 15 two pairs, each pair in series but all designed to act in unison on the common arm 5, to lugs of which the springsv l0, l0, are-hooked at Ill’, ID’. The portions to which the coil cores are ‘attached at l2’, I!’ are the top covers of the encasements 8, 8, connected to the arm 5, which not only vibrates but extendsv through under the pipe 3 the whole length of the device, so that clamps l3, l3 which are welded to the sides of the encasements 8, 8, at 8', 8', will hold the entire device ?rmly in position when the hooks l3’, l3’ are caught over the body of the tool and hooks l3", l3'fof'the clamps are caught under the edge of the tool channel as shown. A rubber guard 8" surrounds the base of encase 30 ment 8. - -_ The vibration of the arm} of the device is tive of an “Air-Way” cleaner with one of the _ e?ected by current from the cord H which may buzzer ‘attachments connected'to the tool there 'lead from any electrical source, but is here shown 36 of. I _ d . - Similar characters of reference refer to like as coming from an extension ‘from the motor of 35 an “Air-Way" cleaner l5 which in turn receives its current from a cord IS, the cords l4’ and H’ and corresponding parts in the several ?gures. _ , Referring to the drawing, the body of the leading to the coils, being merely extensions of floor tool I, having .‘pring support rollers 2, 2' the lead 40 designed to hold it above the carpet to be cleaned, is to be supplied with air suction through the pipe 3. An "Air-way” cleaner tool is provided with channels to hold strokers as 4 but when the present improvement is to be used one of the I I. > I " a The cleaner with the attachment in place is to be used by moving back and forth over the car peted ?oor. ‘As the in-rushing air. lifts the car pet against the strokers, the buzzing or rapid vibrations of the lip or stroker l’ imparts its 45 strokers 4' is to be removed and mounted on the vibrations to the lifted carpet dislodging imbedded 45 vibrator arm 5 carrying the armature 6 and the particles of dust which plain air currents will not channel socket l, in the latter of which the affect. when the tool is pressed down upon the stroker I’ is held securely and to be vibrated so ‘ ?oor between the spring support rollers, the lip or that its lower lip portion shall buzz or beat the stroker 4’ will of course beat upon the ?at lying , 50 carpet which is sucked up against it by the in carpet upon the floor. . rushing air.‘ A rubber‘ substitute strip 4" is placed in the channel of the ?oor tool from which the stroker has been removed and its ‘lower edge is arranged to impinge on the upper side of the 55 tilted stroker 4', making a seal against leakage Having thus described the invention and the operation in the present embodiment thereof, I do not wish to be con?ned to the details as shown since many of them may be greatly modi?ed with out departing from the spirit of the invention. 2 2,120,260 I claim broadly: 1. An attachment unit for a cleaning tool having a ?oor engaging lip, comprising a casing, an electro-magnet carried by said casing having a vibrator arm also carried by the casing and car >10 spaced spring clips carried by the casing and nt ting over the exterior of said nozzle for detach ably connecting said supplemental unit to the. floor tool. ~ , 6. In a pneumatic cleaner, an elongated ‘suc rying another lip for said tool, means for de tion nozzle, supplemental non-‘meta'llic'lip mem tachably connecting the casing to the tool and ' bers carried by the nozzle along the longitudinal ' means for bringing electric current to the elec edges thereof and de?ning a mouth, a vibrator tro-magnet. actuating unit connected to the nozzle externally 2. In combination with the floor tool of a suc . tion cleaner having an unobstructed suction in let, a vibrator unit detachably secured to the floor tool comprising a casing, an electro-magnet and vibrator arm carried by the casing, spring 15 clips for detachably connecting the casing to the exterior of the ?oor tool, and a ?oopengaging lip carried by the vibrator arm. 3. In combination with a suction cleaner hav ing an elongated nozzle with an unobstructed suc tion inlet,-a vibrator unit det'achably connected to the nozzle externally of the suction inlet, com prising a pair of casings each carrying an elec tro-magnet, a common vibrator arm carried joint lyby both of the casings, a ?oor-engaging lip 25 operated by the vibrator arm, and clamps car ried by said casings for detachably securing said unit to the nozzle. ‘ , 4.
