LINT TRAP Filed April 5, 1948 2 Sheets-Sheet 2 Fig.3.

54 Inventor Kenneth E. Hendricksbn y WW jag Patented May 30, 1950 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to new and useful improvements in lint traps and the primary object of the present invention is to provide a novel and improved attachment for tumbling machines and more particularly those machines employed in laundry plants, dry cleaning plants and dyeing plants for drying and deodorizing clothes, that are so designed as to remove lint from the exhausted air leaving the tumbling machine.

Another important object of the present invention is to provide a lint trap applicable for attachment to a tumbling machine for clothing and embodies a novel and improved filter screen that is manually agitated in a convenient manner to effect a removal of the lint therefrom whereby the lint will descend into a lint chamber which is quickly and readily accessible for cleaning.

A further object of the present invention is to provide a, lint trap that is applied to the exhaust pipe of a tumbler or tumbling machine for clothing and the like and which is disposed in the same room with the tumbling machine so that the said trap can be cleaned quickly during the emptying and refilling operation of the tumbling machine, without the necessity of having to shut down the tumbling machine and without the necessity of having to employ special tools or skilled labor.

A still further aim of the present invention is to provide a lint trap that is simple and practical in construction, strong and reliable in use, small and compact in structure, neat and attractive in appearance, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended,

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a perspective view of the lint trap constructed in accordance with the present invention, and showing the same removed from a tumbling machine, and with parts of the intake pipe and outlet pipe thereof broken away and shown in section;

Figure 2 is a longitudinal vertical sectional view taken substantially on the plane of section line 2--2 of Figure 1;

Figure 3 is a longitudinal horizontal sectional view taken substantially on the plane of section line 3-3 of Figure 2;

Figure 4 is a transverse vertical sectional view taken substantially on the plane of section line 4--4 of Figure 2, and with parts removed therefrom; and,

Figure 5 is a fragmentary transverse sectional view taken substantially on the plane of section line 5--5 of Figure 1, and showing the locking device that is employed in conjunction with the present invention.

Referring now to the drawings in detail, wherein for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral l0 represents a substantially rectangular casing or housing of any suitable material generally, that includes a bottom wall [2, an upper wall l4, a forward wall or end wall It, a rear wall or end wall It, and a pair of side walls 20 and 22. One of the side walls, for example side wall 20, is formed with a longitudinal opening 24 in its lower portion and receives a door or panel 26 that is hinged as at 28 to the side wall 20.

The hinged panel 26 supports a rotatable bar or pin 30 the inner end of which is provided witha fixed locking lip or lug 32 that engages the inner face of an upstanding lug 34 that is rigidly secured to the bottom wall l2 for normally holding the panel 26 in a closed and locked position. A finger grip 36 is secured to the outer end of the bar 30 for rotating the same into and out of a locked position with the lug 34.

The forward wall I6 of the casing I0 is provided with an entrance opening 38 in the upper portion thereof that is disposed centrally within a collar or sleeve 40 that projects outwardly or forwardly from the forward wall It and which engages the inner surface of an exhaust or intake pipe 42.

Projecting upwardly from the upper wall 14 of the casing I0, is an annular sleeve 44 that engages an outlet pipe 46. The upper wall [4 is provided with an exit opening 48 that communicates with the sleeve 44.

Fixed to the inner surface of the forward wall [6 and below the entrance opening 38, is the flanged end portion 50 of a substantially horizontal, lower bafile plate 52 the free rear end of which terminates in spaced relationship from the rear wall l8 and is turned upwardly to provide a substantially vertical section 54 that opposes a portion of the entrance opening 38.

The numeral 58 represents a downwardly and. rearwardly inclined upper baflle and support plate that opposes the exit opening 48. One end 58 of this plate 56 is fixed to the upper wall I4 of the casing l0 between the exit opening 48 and the forward wall [8, and the remaining and lower end 60 of this plate 56 terminates above and rearwardly from the vertical section 54 of the lower bafile plate 52 to provide a transverse opening 62.

Hinged to the rear wall l8 of the casing I0, is the upper edge 64 of a rear baffie plate 66 that supports pivotal holding bars 68 the free ends of which terminate in bearing fingers 10 for engaging strips or lugs 12 fixed to the inner surface of the rear wall 18, to normally hold the bafiie plate 66 in a forwardly and downwardly inclined position as shown in Figure 2, opposing the trans verse opening 62 between the baflies 52 and 56. When the bearing finger 10 are disengaged with the strips 72, the bafiie plate 66 will drop to the dotted line position shown in Figure 2.

Extending transversely between the side walls and 22 of the casing 10, is apivot shaft 14 that is spaced slightly adjacent and above the lower edge 60 of the upper bafile plate 56. This pivot shaft 14 is fixed to one edge of a substantially rectangular filterunit orscreen'16 the upper edge or free edge 18 of which is normally engaged with the inner face of the upper wall 14, to retain the filter-unit spaced parallel tothe-bafile plate 66.

. It should benotedythat when the baffle plate 55 is raised in its normal position or inclined posi tion, the upper edge 64 thereof will engage the upper edge 180i the filter screen 76 to limit the downward pivotal movement ofthe latter,howeven-when the bafileplate is lowered orwhen the same is in the dotted line position as shown in Figure 2,the filter screen 16 may be easily pivoted to a vertical position illustrated'bydotted lines in Figure 2. I

Integrally formed with the pivot shaft 14 at one'end thereof, is 'a lever or handle 80 that is casing 10 will pass :between the baffle plate 52 and 56 through the-opening 62 engage the inclined rear bafile plate 66 and will be directed through the filter screen 76 and hence outwardly through the exit opening -48. As the .lintcarried by the air-engages the filter screen 16 the same will .be retained thereon wherebythe air leaving the casing 10 will be .filteredandfree efrom lint.

To remove the lint from the screen 16, it is merely necessary to actuate the lever 80 in a raising and lowering motion which will cause the lint carried by the screen 16 to drop therefrom into the chamber 82. The chamber 82 is easily accessible by raising the hinged panel 26 so that the present casing I0 and parts thereof may be quickly and readily cleaned for continuous use.

.In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the device will be quite apparent to those skilled in' this art. A more detailed description is accordpreferred embodiment of the invention the same is susceptible to certain changes fully comprehended :by the spirit of the invention as herein an entrance opening-therein, said upper wall having an exitopening therein, apair of bailies mounted in the casing and arranged toprovide a restricted opening for air entering the casing from the entrance opening, a filter'screenrpivoted within the casing adjacent the exit opening, means for agitating the filte'r'to remove lint therefrom, means provided in the casing for receiving lint removed from they filter during agit-ation thereof, and an inclined baffle hingedly mounted within the casing having an upper edge for normally limiting 'the'pivotal movement of the filter in one direction, and'means normally retaining the hinged bafflein an inclined position and spaced parallel .to' the filter.
