ERNEST I. DARGIN, OF LOS ANGELES, CALIFORNIA, ASSIGNOR OF ONE-HALF T0 CHARLES S. BROWN, 0F LOS ANGELES, CALIFORNIA.

FLUSHING APPARATUS FOR GARBAGE-CHUJJES.

To all whom it may concern:

Be it known that I, ERNEs'r P. DARGIN, a citizen of the United States, residing at Los Angeles, county of Los Angeles, and State of California, have invented certain new and useful Improvements in Flushing Apparatus for Garbage-Chutes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in garbage chutes of the character employed in hotels, apartment houses, etc., and of the construction which extends the entire height of the building and which has openings at each floor for the introduction of garbage. My present invention relates specifically to the means for automatically supplying water to these chutes for flushing purposes, whenever a door is opened for the introduction of garbage. This invention discloses in its general characteristics those disclosed in. my simultaneously pending application entitled Improvements in sanitary garbage chutes, but the claims will be drawn to cover the flushing construction alone.

An important feature of my present constructionconsists in the location of the water pipe or conduit from which the supply is taken at each floor, within a closed chamber or compartment adjacent the body of the chute and in communication therewith, whereby in case of a leaky valve, the escaping water will drain into the chute and therefore can do no damage to the building. Heretofore, so far as I am aware, chutes of this character have had the valves for controlling the supply of water to the chute,

struction and arrangementof the door of v the chute at each fioor, whereby as the door is'opened, the water is automatically turned on, while when the door 1S closed, it is turned,

Specification of Letters Patent.

Application filed March 8, 1915. Serial No. 13,067.

ofi. In the drawings, I have illustrated. both a sliding and a hinged door for accomplishing this object.

Having briefly outlined my improvement, I will proceed to describe the same in detail, reference being made to the accompanying drawing, in which is illustrated an embodiment thereof. In this drawing,-

Figure 1 is an elevation of a garbage chute of my improved construction, the same being illustrated in use, enough of the chute being disclosed to permit the explanation of its use on any floor of a building, regardless of the number of floors.

Fig. 2 is a fragmentary elevation of the construction, partly in section, the view being taken in the direction of arrow 2, Fig. 1, the parts being shown on a larger scale.

Fig. 3 is a similar view shown entirely in elevation.

Fig. 4 is a vertical section taken on the line 45, Fig. 3, looking toward the right, and showing the door in the open position.

Fig. 5 is a similar view showing the door in the closed position.

Fig. 6 is a view similar to Fig. 4:, but showing another form of door construction. In this view, the door is shown open.

Fig. 7 is a view similar to Fig. 6, but showing the door closed.

The same reference characters indicate the same parts in all the views.

Referring first to Figs. 1 to 5, inclusive,

let the numeral 5 designate the body of the chute, 6 its upper extremity extending above the roof of the building, and open for ventilating purposes; 7 the garbage receptacle at the bottom of the chute; 8 a vertically movable hood arranged above the receptacle for closing purposes; 9 a lever for raising and lowering the said hood; and 10 a floor of the building where the chute is located, the same being shown in section.

At a suitable distance above each. floor 10, the chute is provided with an opening which is normally closed by a door 12, which, as illustrated in the views now under consideration, is vertically movable in the grooves 13 of channel guides 14 and 15 with which the chute is equipped. The lower members 14 of these guides are built into the housing structure 16 applied to the chute adjacent each opening, while the upper members 15 of these guides are fastened, as by means f ri et it to th u per region of the housing structure 16 and extend above the same, being completely exposed or separated from the body ofthe chute, and are adapted to receive the opposite edges of the door when the latter is-lifted. The upper extremities of the guide members 15 are con;

- spaced at the top and b'ottomby transverse parts 22 and 23. This spacing of- theplates 20 and 21 forms a chamber 24: within the door, into which protrudes a crank arm25, whose outer extremity passes through an openingv 26- formed in the inner wall of a housing27 and whose outer wall 28 is exteriorly cl0sed. Located withinthis housing isa branch pipe 29 which passes through'an opening 30 formed-at the top ofthe housing 27 and is connected within the main water supply conduit--31 by means of a-conduit member 32.

. of: the door, the, spring 39 is stretched or.

Within the chamber 33 of this housing, the branch-pipe 29 is equipped-with-a valve 34:, for controlling the supply of water'to the chute as the dooris opened. The outer extremity of "the crankvarm 25 is connected with. this valve, the arrangement being such that when the door is closed or in the position shown in Figs..2,f3-:and '5, the valve is closed and the watercutoftfrom the chute.

This crank arm, when the door is closed,

is downwardly inclined from the valve at.

an angle of approximately 45 degrees and is provided with a slot 35 which is entered by a pin '36 fast uponthe door. Connected with this crank arm at a suitable-point between its extremities, is one end of a spiral spring 39, whose upperextremityis connected with the-part 22 at the top of the'door, as shown at 37.

"Gonsequently, as the dooris raised, the crank arm 25 is carried upwardly therewith and imparts suflicient movement to the valve 34 to open the-same. The position of the crank-arm when the door has reached its upwardlimit of movement is indicated by dottedlines in Fig. In other 'words,when the crank arm .2 5 has-rea ched this position, the door cannot be raisedfarther, since the pin 36 engagingthe slotj35 of the crank arm will not permrt further movement. 5 During this upward movement placed under tension, since the point "37 where the upperextremity ofthe spring '39 is connected with the door, must travel .far-

- ther than the point 38' wher'e -this same 1 spring-is connected with .the'crank arm. In other words, the point 37 must travel the full distance between the full line position of the pin 36 in Fig. 2 and the dotted line position of thesaid pin in the same figure, while the point'38 can only travel the distance betweenthe full line position of this point in Fig. 2 and the dotted line position of the same point in the same figure, hence the spring 39 will be distended and its recoil action will aid in returning the door to its closed position, and also perform the function of closing the valve 34..

The outer wall of the housing 27 is downwardly inclined at its lower extremity, as shown at 40, whereby any water which leaks into the chamber-33 of this housing will pass downwardly into the chute through an opening 4 1 'formed .in the inner wall of the housing, and communicating with the interior of the chute.

In the form of construction shown in Figs. 6 and 7, a door 42 is hingedto a housing 43,-whichis offset from the body of the chute. Within this housing is located a branchpipe or conduit 44 in which a valve 45 is located. Connected with this valve is a crank arm 46 with which one extremity of a rod 48 is pivotally connected, as shown at 47,-the opposite extremity of the said rod being pivotally connected as shown at 49, with an inwardly projecting crank arm 50, which is secured-to the lower extremity of the door, and is raised by the opening movement of the door, as illustrated in Fig-6. The door is normall y held in the closed position bymeans of a weight 51 which is connected withthc inner extremity of the crank arm 50 this weight also has the function of aiding, in closing the door.

The housing structure in which the pipe 44, its valve and the means connected with. the door for operating the valve, are located, is ofi'set from the body'5 of the chute in such a manner as'to be out of the path of the garbage passing thcrethrough from the floors above any door and its connections. The lower extremity-of the branch water supply pipe 44 extends transversely of the chute and parallel with the lower edge of the door, as shown at 52 inboth forms of constructions, this pipe member being perforated for the escape of water into the chute for flushing purposes. In the form of construction shown in Figs. '6 and 7, a defiectingplate 53 extends inwardly from the outer wall of the housing below the-door and above the transverse perforated member 52 of thewater supply pipe, and prevents anywater from escaping into the apartment when the door is open.

From the foregoing description, the use and operation of myimproved flushing ati tachment for garbage chutes will be readily understood. In'the form-shown in-Figs. 1 t0;;5, inclusive, the door which is provided with a handle 54;for thepurpose, is raised till for opening purposes, whereby it is carried upwardly so that its opposite vertical edges engage the channel members 15. The door is shown in this position in Fig. 4, the spring 39 being distended as illustrated in this view. The opening movement of the door actuates the crank arm 25, with which the said spring is connected, sufiiciently to open the valve 34, whereby water is allowed to enter the chute for flushing purposes.

In the form of construction shown in Fi s. 6 and 7, the door is swung outwardly tor opening purposes (see Fig. 6), and during this movement, the inner extremity of the crank arm 50 is moved upwardly sufiicien'tly to actuate the valve 45 for opening purposes, through the medium of the crank arm 46 and connecting rod 48. The act of closing either form of door, reverses the movement of the valve piece and cuts 0d the water so that there shall be no escape of the water when the door is open.

Having thus described my invention, what I claim is,

1. A garbage chute having a water supply pipe connected therewith to deliver water thereto, a valve in said pipe, a door slidably mounted, a crank arm connected at one extremity with the valve piece and at its opposite extremity with the door by means of a pin and a slot, and a spring connecting the door with the crank arm at a point be tween the pin and the valve.
