J 7,2505. v.5 62 I I ATTORNEY v wlTNE S v g Patented June 24, 1930 UNITED; STATES PATENT OFFECE JACOB HELGESEN, OF WHITE PLAINS, NEW YORK GARBAGE CHUTE This invention relates to improvements in garbage chutes.

The primary object of the invention resides in a garbage receptacle for facilitating the disposal of garbage in a sanitary manner without necessitating a trip exteriorly of a building in which the device is installed, and which will be found convenient for use in hotels, restaurants, and hospitals, as well as for homes.

Another object of the invention is to provide a built in garbage receptacle which includes a chute, access to which may be had from the interior of a building through a door provided therein, while the lower end of the chute enters an enclosed pit exteriorly of the building inwhich a garbage receiving can is placed to receive the garbage dropped into the chute, the door when opened causing the actuation of another door within the chute to seal the same to preclude the odors of the garbage can from escaping into the interior of the building.

Another object of the invention is the provision of a garbage chute through which a circulation of atmospheric air is passed to expel the odors therefrom, and inwhich a pipe spray is arranged to allow flushing of the chute as required.

With these and other objects in view, the

invention resides in certain novel construc-.

Application filed October 5, 1928. Serial No. 310,553.

Referring to the drawings by reference characters, the numeral 10 designates the vertical outer wall of a building structure, 11 the flooring on the inside of the wall, and 12 a concrete foundation or base, the latter having a pit 13 provided therein below the exterior surface level. The pit opens onto the surface through an opening 14 in the top thereof which is normally closed by hinged door 15 having air openings 16 therein.

' Installed on the interiorside of the wall 10 is a chute 17 which is constructed of an upper casing section 18 which rises above the floor level and which has its lower end fitting within a casing section 19 which depends below the plane of the floor 11 into arecess 20 in the concrete base 12, which recess communicates with a' downwardly inclined passage 21 which enters the pit 13. A garbage receiving can A is placed in the pit to receive the garbage entering the same from the inclined passage of the chute, however, other cans may be stored .within the pit as they become filled and pending their removal by the garbage collector.

The top end of the casing section 18 is formed with a right angularly disposed neck 22 which extends through the side wall 10. A grating 23 is mounted on the outside-of the wall against the open end of the, neck 22 ancl has baffle plates '24: which deflect the odors from the chute downwardly and prevent the insertion of refuse into the chute from the exterior of the side walls. The inner top of the casing section 18 is inclined at an angle and has an opening 25 therein for register with an opening 25 in the housing 26 which fits against the wall 10 and floor 11 and is anchored thereto by anchor screws 27.. The outer housi'n 26 may be of a cast metal suitably porcelained to impart a clean and sanitary appearance thereto. The housing conforms to the shape of the upper portion of the chute and is bolted thereto while a hinged door 28 is mounted thereon for sealing the opening 25.

The anchor screw 27 above mentioned is of a novel construction and includes a. threaded shank 29 having an enlarged threaded head 30 provided with a kerf 31.

The anchor screw is threaded into its supporting structure by inserting a screw driver into the kerf and turning the same, and after being screwed home, a rounded finishing head 32 is threaded to the head 30 of the screw.

For the purpose of sealing the chute upon opening of the door 28 to prevent odors from the pit from escaping into the build ing, I provide a door 33 hinged to the rear wall of the casing section 18 adjacent the top thereof. The door is of such length as to strike the front wall of the casing section when in a closed position, in such a manner that the door is rearwardly inclined. The door 33 is operatively connected to the door 28 by a flexible chain 34, whereby, opening of the door 28 to deposit garbage in the chute will cause the sealing .of the chute by the door 33. The deposited garbage will be supported by the door 33, but when the door 28 is closed, the door 33 will automatically drop under its own weight and release the garbage to the bottom of the chute.

For keeping the interior of the chute "in a sanitary condition, I mount a pipe spray 35 within the chute at the top thereof and which is connected with a water supply pipe, the flow thereto being controlled by a regulating valve 36. The water discharged from the spray pipe when turned on, washes down the inner side walls of the chute to effectively clean the same, while the bottom of the pit 13 has a drain 37 therein for carrying off the water during a spraying operation. The chute may bc flushed as often as is necessary.

. seen that when the door 28 is in theposition shown in full lines in Figure 3 of the draw mg, atmospheric air will circulate through the chute and pit to prevent the accumulation'of odors therein, while any odors which may be present inthe chute are sealed upon opening of the door '28 to deposit refuse therein. As the garbage can A becomes filled, it may be removed upon opening of the door 15 and an empty can substituted therefor, or the filled cans may be stored in the pit pending their removal by the garbage collector.

lVhileI have be the most desirable embodiment of my invention, it is obvious that many of the details may be Varied without in any way departing from the spirit of my invention, and I therefore do not limit myself to the exact details of construction herein set forth nor to anything less than the whole of my invention limited only by the appended claims.

hat is claimed as new is 1. In a garbage chute, an enclosed chute,

From the foregoing description, it will be described what deem to one end of which opens directly to the atmosphere, a pit at the bottom of said chute, an openable cover in the top of said pit, a door at the top of said chute through which refuse may be deposited upon opening of the same, and means operable upon the opening of said door for sealing the lower end of said'chute therefrom, said cover having ventilating openings therein for circulating atmospheric air through said chute and pit when said door is in a closed position. 7 2. In a built-in garbage chute, the combination of a building structure having a side walland a foundation, a chute having its upper end opening through said side wall to the atmosphere, a pit in said foundation into which the lower end of the chute enters, a door for access to said pit, and

a door in said chute through which refuse 1 said chute through which refuse may .be de posited into said chutev upon opening of the same, and chutesealing means for sealing said chute below said door upon opening of the latter to prevent odors from the pit and lower end of said chute from passing said open door. v

i. In a building structure, a pit exterior-1y of the same below the level of the earths surface, a perforated cover in the top of said pit, a chute having its lower end opening into said pit and its upper end opening to the atmosphere whereby air may freely circulate through said chute, a door in said chute accessible from the interior of said buiiding structure, and means operable by the opening of saiddoor forsealing said chute below the same, substantially as and for the purpose specified.

In testimony whereof I have affixed signature Sept. 5, 1928.

JACOB HELGESEN.
