WINDOW CLEANING DEVICE Mmmm Jan. 21, 1964 United States Patent O ,118,166 WINDW CLEANING DEVICE Sidney R. Bell, Stamford, Conn., assigner to `let Brush Products, Ine., New York, NX., a corporation of New Jersey Filed Feb. 11, 1963, Ser. No. 257,675 9 Claims. (Cl. 15-531) This invention relates to devices for cleaning windows, wherein the device includes a brush head, into which water can be discharged in the operation of cleaning and scrubbing a window and, further, a exible wiper blade for linish cleaning the window or removal of water applied to the windowpane. More particularly, the invention deals with a device of the character described having means for manually pumping water from a reservoir in the handle of the device through a discharge tube leading to the brush head.

The novel features of the invention will be best understood from the following description, when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed and, in which, the separate parts are designated by suitable reference characters in each of the views and, in which:

FiG. l is a sectional and face view of a device made according to my invention, with the brush head detached.

FIG. 2 is a section substantially on the line 2-2 of FG. l, with the brush head applied.

FG. 3 is an enlarged sectional view showing a modied form of construction, with the device in the window cleaning use thereof; and

FiG. 4 is a view, similar to FIG. 3, showing the device m a reverse position.

ln FIGS. l and 2 of the drawing, I have shown one adaptation and use of my invention and, considering FIG. l, represents the tubular handle member, having a ribbed outer surface, as indicated, in part, at 11 to provide a secure handgrip, the handle member having a threaded cap 12 at its free end in threaded engagement therewith, the cap having a rubber or other washer 13 to seal a liquid, diagrammatically illustrated, in part, at 14, in the bore or reservoir 15 of the handle member. The other end of the handle member is open, as seen at 16, and fitted and secured in this end of the handle member is an elongated tapered tubular body 17, in the end of which is secured a fitting element 18.

In the handle member 143, inwardly of the open end 16, is a transverse pump cylinder 19, in the open end of which is mounted a closure ring 2t), in which is supported a linger knob 21 of a piston 22 operating in the cylinder 19. A spring 23 is arranged in the cylinder and engages the piston to normally support the same against the ring 20, as shown in FIG. l of the drawing. The cylinder 19 has three radially extending sleeves, one sleeve 24 extending into the open end 16 of the handle member and the other two sleeves 25 and 26 extending into the reservoir 15. The sleeves 24 and 26 have apertures opening into the cylinder 19, which apertures are controlled by spring seated ball valves 27 and 28, respectively. The spring of the valve 27 seats in a multiple diameter coupling tube 2e', with which a liexible tube 30 is coupled, the latter extending to and being mounted in the lower portion of the element 18, as clearly noted in FIG. 2 of the drawing, to communicate with a bore 31 in said element, having a discharge 32 into the chamber 33 of a cup-Shaped extension 34 of the element. This extension is disposed angularly to the longitudinal plane of the body 17, as clearly noted in ilG. 2 of the drawing. The outer peripheral surface or" the extension 34 is bevelled to provide frictional engagement of a brush head 35 therewith, the brush head being in the form of a ring llfl Patented dan. 2l, 1954 having circumferentially arranged bristles 36 thereon, as diagrammatically seen in FIG. 2 of the drawing.

Returning now to the structure of the cylinder 19, it will appear that the spring controlling the ball valve 2S seats on a cap 37 mounted on the sleeve 26. Mounted in the sleeve 2S is a tube 33, which extends to a position adjacent the lower end of the reservoir 1S, as seen in iilG. l of the drawing, so as to be exposed to substantially all of the liquid 14 in the reservoir and a ball check valve 39 seats on the upper end ot the tube 38, so as to prevent discharge of liquid from the cylinder 19 as and when the piston 22 is actuated for discharging liquid from the cylinder up through the tube 3l) and into and through the brush head 35' for application to a surface to be cleaned. Considering FIG. 2 of the drawing, it will appear that the cylinder 19 has laterally extending apertured ribs il at sides thereof, so that, in filling the device through the cap end 12 with a suitable liquid, the device can be lled to an extent greater than the capacity of the reservoir 15 proper, in that this liquid can pass upwardly through the tubular body 17 and passed downwardly into the reservoir 15, as the liquid is consumed.

in the use of the device, it will be understood that one or two manual strokes of the piston through actuation of the linger knob 21 is essential to draw the liquid 14 from the reservoir into the cylinder 19 and in discharging this liquid from the cylinder up through the tube 3i?. in this latter operation, the valve 39 is seated. The valve 27 serves to hold liquid in the tube 3l) as the device is continuously used so that, in actual practice, in a stroke operation of the piston 22, liquid would be discharged through the head and this discharged liquid would be replaced in the outward stroke of the piston through the medium of the spring 23, which sucks the liquid from the reservoir into the cylinder 19.

The spring actuating the valve 23 will be a very light spring, sucient to normally maintain the valve in a seated position, but to enable liquid to drain from the cylinder when the device is not in use and positioned or stored in the upright position shown in FIG. l in providing a discharge from the cylinder 19 and, in some instances, this discharge can be through a tube extending from the cap 37, as indicated by the dot-dash showing at 37 in FG. l.

The element 18 has an angularly extending flared tongue 411, shown in section in FIG. 2, and the flare of which is clearly illustrated in FG. Il. Descriptively speaking, the brush head may be said to be angularly disposed on one side of the body 17; whereas, the tongue is angularly disposed at the opposed side thereof. Mounted on the tongue i1 are a of wiper blade holding plates i2 riveted or otherwise fixed together, as seen at 43 in FIG. l of the drawing, in securely supporting the plates on the tongue 41 and in gripping a wiper blade 44 in the jaw side portions 45 of the plates, these jaws engaging an enlarged portion 46 on the blade '44, as clearly illustrated in FIG. 2 of the drawing. it will be understood that, after the window or surface has been cleaned by actuation of the brush thereover, the wiper blade can be utilized in removing liquid from the surface, as with other devices of this type and kind. At this time, it is well to mention that, while the device has a der'inite use as a window cleaner, it can be utilized for cleaning and wiping any type and kind of surface and, lfurther, can be utilized in operation of the device with the brush and wiper end in a raised position v ith respect to the hand or operator, or in a lowered poistion.

'In some instances, a one unit device can be utilized and sold for two distinct purposes, namely as a device, including the wiper blade or a device in which the wiper blade and its supports are removed and the tongue 14 aliarse 3 would then be used as a scraper blade in uses of the device as a dish cleaner, in which latter use, the liquid i4 can be in the form of a detergent discharged into the brush head, similar to devices, such as shown in Patent NurL ber 2,772,430, granted December 4, 1956.

ln devices of the kind referred to above, i have shown a modified adaptation oi FlGS. 3 and 4. and, in these figures, dit" represents the handle member, l?" the tubular body, 19" the cylinder, 2'9" the coupling tube arranged on the sleeve 24. iAt 43 are indicated ribs, similar to the ribs il of FlG. 2, except that 4d are not apertured. With the structure shown in FlGS. 3 and 4, the sleeves 25 and 2d are omitted and a single sleeve extension 47 is employed, having a bore 5:18 angular in cross-sectional form and communicating with the cylinder l. This angular bore provides passage of rluid into the cylinder when the parts are in the position of FIG. `Mounted on 47 is a two-part valve plug 49, comprising the parts Se and 5l adhesively or otherwise secured together along the parting line k52. Extending from the parting line 52, the part 5i has a tubular valve seat 53 tapered to t snugly in a socket 54 in the part 5d. The part 5d' has a corresponding valve seat 55. A ball check valve S6 operatively engages both of these seats 5'3 and 55, as will appear from a consideration of FlGS. 3 and 4.

ln this connection, it is pointed out that most of the reference characters referred to above and `which will follow are applied to the showing in FIG. 3 and will not be completely repeated in the showing in FIG. 4.

Communicating with the bore extending from the seat 53 is a port or passage 57, which also passes through the part 5t? and opens into the reservoir l5' of the handle member 'lili'. In like manner, the part Sil has a port 5d extending from the seat SS and communicates with a pipe or tube 38', which would be similar to the tube 3S of FIG. 1, the latter extending to the lower portion of the reservoir l5. With the parts in the position shown in lFlG. 3, the modified form of device can be used, similarly to the device as shown in FIGS. 1 and 2, the liquid drawn from the reservoir v passing into the cylinder lg' through the lport d8, this passage bein(7 controlled by a ball valve 59, as is indicated by the arrow in FG. 3 of the drawing.

In the reverse use of the device as noted in FIG. 4, liquid in the reservoir 15 will be positioned in the reservoir around the cylinder yi9 and, in operation of the piston in the cylinder 19', this lliquid will be drawn into the cylinder through the port @il in the direction of the arrows of FlG. 4 with the ball 56 in the seated position shown in said ligure to prevent discharge through the tube 31S. ln this same connection, it will be apparent that, in the use as sh wn in FlG. 3, the ball S6 seals the discharge through the port 57. In FIG. 3, it will be understood that the liquid positioned in the cylinder l5" is discharged upwardly through i7 to the brush head; whereas, in FIG. 4, the discharge is through the same head, which is then directed downwardly.

ln the present showing, no attempt has been made to identify types of materials employed in the various parts in the shading used. The parts could be composed entirely or" metal, except, possibly, the tubes as at 39, 38, 3S. However, in certain uses of this device, all of the parts, except the springs and, possibly, some of the ball valves and the plates `4t2, could be composed of plastic material, even to the structure oi the vwiper blade which, in the present illustration, is indi ated as composed ot rubber.
