M. G. BURWELL CONDUIT CLEANING MECHANISM Filed April 4, 1939 Patented Oct. 29 1940 PATENT OFFICE CONDUIT CLEANING MECHANISM Maurel G. Burwell, Columbus, Ohio Application April 4, 1939, Serial No. 286,018
7 Claims.
This invention relates to mechanism for clean ing elongated conduits of the type employed in air conditioning systems. The primary object resides in the provision of a cleaning device having a collapsible brush head at one end of an elongated flexible handle and "further providing a container in which this handle portion may be placed when the device is not in use.
Another object resides in the provision of a drum-like container having a reel rotatably' mounted therein and coiling an elongatedflexible strip in said reel, the-strip being provided at one end with a collapsible brush head to be inserted in a heat conducting pipe to remove dirt or other foreign matter therefrom.
It is also an object to provide a novel brush head having a plurality of arcuate sections and means for supporting the sections for adjustment relative to one another in order that the head -may becollapsed prior'to the insertion in a conduit to becleaned and then expanded prior -.to withdrawal from the conduit Other objects will be apparent from the following description and the accompanying drawing in which: I I i Fig. 1 is a perspective view of a cleaning device formed in accordance with the present invention;
Fig. '2' is a plan view partly in section showing the container for the elongated handle of the cleaning mechanism. H r
Fig. 3 is a vertical transverse sectional view sitaken dfithplane indicatedjby the life III-III orr'ig.2;-'
Fig. 4 is a, vertical longitudinal sectional view taken through the collapsible brush head;
Fig. 5 is a detail sectional view taken on the plane indicated by the line VV of Fig. 4.
Referring more particularly to the drawing,
the numeral l designates the casing of the improved conduit cleaning device. This casing is formed from a pair of telescoping pan-like sections 2 which, when assembled, form a drum-like housing having closed ends. The sections 2 are held in their assembled relation by screws 3 passing through the end walls of the sections into a short hollow shaft 4. Rotatably carried by the shaft is a sleeve 5 having a flange 6 formed atone end thereof. Secured to the flange 6 is a circular plate I provided at its periphery with a laterally bent corrugated extension 8 as illustrated in Fig. 2. The plate 1, together with the extension and the sleeve 5 form a reel in which an elongated flexible steel strip 9 may be coiled as shown in Fig. 2.
To provide for the insertion of the strip in the container, one end wall is formed with an opening Ill over which a guide II is fastened. The outer end of the guide has a narrow slot coniormingsubstantially to the cross section of the strip 9 and through which the strip may pass when being inserted into or withdrawn from the housing I. The opposite end of the guide flares as at l2 to accommodate the strip either when one coil or many coils are placed in the reel. Theouter end of the strip has a threaded bolt l3 carried thereby for connecting the strip to a coupling member I formed with the end of a rod IS. A rectangular block I 6 is slidably positioned on the rod l5 and has angularly disposed side faces in which are formed threaded openings for the reception of screws employed in securing spring strips l8 thereto. By reason of the angularity of the side faces of the block l8, the spring strips will diverge from the longitudinal axis of the bar l5.
In the form of the invention illustrated, four Y strips l8 are provided, alternate strips being of have bristle elements 22 projecting from the outer surfaces thereof. The outer endsof the bristles are also cut to cause them to terminate in a curved brushing surface. By reason of the difference in length between adjacent strips. I8, the brush sections will be disposed in longitudinally spaced order as shownin Fig. 4. The end of the rod i5 adjacent the brush elements has a spreading plate 23 secured thereto. This plate is formed with slots through which the strips l8 extend and move when the plate is adjusted relative to .the body It by moving the rod therethrough.
By reason of the inclination of the strips I 8, movement of the plate 23 toward the block I 6 will cause the outer ends of the strips to separate and increase the outside dimension of the brush head. This operation will be reversed when the plate is moved from the block.- A coil spring 24 extends between the plate 23 and the block it to facilitate the movement of the plate in the brush expanding operation.
In use, the brush head is collapsed and insorted in a conduit to be cleaned. when the head has been inserted to the extent desired, a sharp pull on the handle 9 will cause the plate 23- to move toward the block l6 and expand the head at which time the brush or bristle elements will engage the inner surfaces of the conduit. Outward movement of the handle and the brush head will withdraw all dirt and foreign matter from the conduit. After the cleaning operation has been completed, the flexible handle may be stored in the container by inserting it through the guide II. To facilitate the storage of the device, the brush head may be detached from the end of the handle.
While the preferred embodiment only has been illustrated, it is obvious that many minor changes may be made in the construction and relation of parts without departing from the spirit and scope of the invention as set forth in the following claims.
