Patent number: 10166559Abstract: A hose end sprayer has a sprayer lid and a container. The sprayer lid has a cap with a pair of bottle connectors formed of single-ended, fixed diameter, threaded sleeves of different radii mounted on the underside of the sprayer lid's cap. The connectors and a threaded adapter allow the sprayer lid to be connected with containers having mouths of different sizes, including containers in which liquid chemicals are sold. A liquid conduit extends across the cap between a hose inlet on one end and a spray nozzle on the other end, with a siphon tube intersecting the conduit within the periphery of the smaller of the bottle connectors, with mixture of pressurized carrier water entering the liquid conduit at the hose inlet with liquid chemical siphoned from the container through the siphon tube. The chemical/water admixture is expelled from the spray nozzle.Type: GrantFiled: September 2, 2014Date of Patent: January 1, 2019Assignee: Root-Lowell Manufacturing CompanyInventor: Michael T. Clarke

Publication number: 20100019062Abstract: A manually pressurizable house and garden tank sprayer employing a separate diluent tank and liquid chemical concentrate container, wherein the concentrate container is mounted to and carried by the diluent container or by a spray wand. The tank containing diluent is pressurized by a conventional hand pump, and the same hand pump pressure pressurizes the concentrate container. The diluent and concentrate chemical are not admixed until just before the liquids are dispensed, so that unused chemicals are not contaminated or diluted until they are used.Type: ApplicationFiled: July 23, 2008Publication date: January 28, 2010Applicant: Root-Lowell Manufacturing CompanyInventor: Michael T.

Patent number: 7643647Abstract: A speaker support system is adapted for use in a suspended ceiling with grid openings and ceiling panels. The system has a speaker support base capable of supporting at least one speaker within a ceiling opening without interfering with the operation of the speaker. A guide flange is integral to the speaker support base and is adapted to align at least a portion of a ceiling tile within the grid opening. A support flange having an offset at each end is integral to the system, connected to the guide flange, and supports at least a portion of the ceiling tile within the ceiling grid opening so that the opening is filled with the speaker support base and the remaining portion of the opening is filled with ceiling tile. The base and guide flange are formed from a single piece of material, which is perforated substantially to at least some of the edges thereof.Type: GrantFiled: March 8, 2005Date of Patent: January 5, 2010Assignee: Lowell Manufacturing CompanyInventors: Wilhelm R.

Publication number: 20090224072Abstract: A hose end sprayer comprising a sprayer lid and container includes multiple bottle connectors formed of single-ended, fixed diameter, threaded sleeves of different radii mounted on the underside of the cap of the sprayer lid. The connectors allow the sprayer lid to be connected with containers having mouths of different sizes, including containers in which liquid chemicals are sold. A liquid conduit extends across the cap between a hose inlet on one end and a spray nozzle on the other end. A siphon tube intersects the conduit within the periphery of the smallest of the bottle connectors. The siphon tube carries liquid chemical from a container connected to the sprayer lid, such as a bottle of concentrated liquid, into the liquid conduit, where the liquid mixes with carrier water entering the liquid conduit at line pressure from an external hose connected to the hose inlet. The liquid carrier water mixture is then expelled from the nozzle.Type: ApplicationFiled: March 7, 2008Publication date: September 10, 2009Applicant: Root-Lowell Manufacturing CompanyInventor: Michael T. Clarke

Publication number: 20070269254Abstract: An applicator system comprises a reservoir, a conduit extending from a first end at the reservoir to an opposite terminal end, an applicator connected with the conduit, a flow control engaging the conduit, and a holder releasably coupling with the applicator. The applicator has a liquid impermeable back, an opposite porous face, and a plenum. The plenum, situated between the back and face, releasably couples with the conduit terminal end and distributes fluid to the face. The face and plenum may be replaceable and disposable. The holder is a rigid member that releasably couples with the applicator, provides a structural foundation to the applicator, and includes a handle for manipulation by a user. An extension can be employed to connect the flow control to the handle, effectively extending the length of the handle. A helical coil portion of the conduit can be conveniently wrapped around the extension to prevent kinking.Type: ApplicationFiled: May 7, 2007Publication date: November 22, 2007Applicant: ROOT-LOWELL MANUFACTURING COMPANYInventor: Michael Clarke

Patent number: 7120269Abstract: A lay-in tile type system is disclosed for supporting speakers in a new or existing suspended ceiling includes a perforated base section providing maximum free air space. A perforated surface also helps the lay-in tile system blend in with the overall suspended ceiling in which the system is installed. The system further provides integral flanges that form a T-shaped member to support at least a portion of an adjacent ceiling tile, obviating the need to purchase, cut and install a replacement grid member. The base and the flanges are constructed from a single sheet of material that is folded to form the flanges. The base is sized to fit within a portion of a conventional ceiling tile grid opening, and has substantially ninety degree comers so that the ceiling grid opening is completed by a ceiling tile sized with a simple straight cut, simplifying installation.Type: GrantFiled: October 5, 2001Date of Patent: October 10, 2006Assignee: Lowell Manufacturing CompanyInventors: Wilhelm R. Lowell, Carey C. Porter, Jeffrey R. Garstick

Patent number: 5054076Abstract: A device for providing limited-access volume control for at least one remote speaker in an audio system, the device comprising a lockable, key-actuable attenuator that attenuates an input audio signal to provide an attenuated output audio signal. The attenuator is adjustable upon the insertion of a key to selectively adjust the degree of attenuation, and is lockable upon the removal of the key to prevent unauthorized adjustment of the degree of attenuation. The attenuator preferably comprises a transformer having primary and secondary windings. A plurality of tap means is connected to the secondary winding. A lockable, key-actuable, multiple position switch, having a contact corresponding to each switch position, is connected to the tap means with each contact being connected to one of the tap means. The switch can be operated upon insertion of a key to move from position to position and can be locked upon removal of the key.Type: GrantFiled: November 13, 1989Date of Patent: October 1, 1991Assignee: Lowell Manufacturing CompanyInventor: Wilhelm R.

Patent number: 4930686Abstract: A portable sprayer which has a resealable closure, a dispensing valve and a pressure-responsive filling valve attached to a receptacle. As the receptacle is filled with fluid through the valve, air which is entrapped in the receptacle pressurizes the container to facilitate dispensing the fluid. During filling, the inlet valve closes if the pressure of the liquid source to which the sprayer is connected exceeds that within the container by a predetermined amount. The inlet valve also closes when the filling hose is disconnected from the container in order to close the container.Type: GrantFiled: December 21, 1988Date of Patent: June 5, 1990Assignee: Root-Lowell Manufacturing CompanyInventor: Garry L. Ellison

Patent number: 4930664Abstract: A portable sprayer which has a resealable closure, a dispensing valve and a quick disconnect one-way valve attached to a receptacle. As the receptacle is filled with fluid through the one-way valve, air which is entrapped in the receptacle pressurizes the container to facilitate dispensing the fluid. By locking the dispensing valve open or by opening the top closure of the sprayer, and securing a hose to the quick disconnect one-way valve, one can flush the sprayer out by allowing fresh water to flow continually through the system.Type: GrantFiled: June 9, 1988Date of Patent: June 5, 1990Assignee: Root-Lowell Manufacturing CompanyInventor: Garry L.
