EDMUND ROENIUS, OF GRAND RAPIDS, WISCONSIN.

CHUTE.

To all whom 'it may concern:

Be it known that I, EDMUND RoENIUs, a citizen of the United States, residing at Grand Rapids, in the county of Wood and State of Filisconsin, have invented a new and useful Chute, of which the following is a specification.

This invention relates to coal, wood and merchandise chutes intended to be used in basements or other walls through which articles can be passed.

The invention has for one of its objects to improve and simplify the construction and operation of devices of this character so as to be comparatively simple and inexpensive to manufacture, reliable and efficient in use, and readily manipulated.

Another object of the invention is the provision of an improved closing means for the chute composed of operatively connected upwardly and downwardly swinging sections so as to open or close together, one of the sections being glazed to serve as a window, while the other constitutes a hopper, there being improved means for locking the sections in closed position.

lith these objects in view and others, as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawings, which illustrate one embodiment of the invention, Figure 1 is a sectional perspective view of the chute shown inv place in a wall, the closure sections being in closed position. Fig. 2 is a vertical section of the chute with the closure sections open by full lines, and closed by dotted lines. Fig. 3 is a rear elevation with the casing in section. Fig. 4 is an enlarged detail sectional view, showing the latch device for locking the closure sections or doors closed. Fig. 5 is an -enlarged detail sectional view, showing one of the hinges for the upper closure section. Fig. 6 is a detail sectional view, showing` one of the hinges for the lower closure section. Fig. 7 is a detail view of the latch or locking device for the closure sections. Fig. 8 is an enlarged detail sectional view of the means for securing the glass plate in the upper section. v

Similar reference characters are employed to designate corresponding parts throughout the views.

Referring to the drawings, A designates the casing of the chute, which may be of any approved construction, size or shape, and which is set into an opening 1 in a basement or other wall 2, the casing beingprovided with a marginal outer flange 3 which bears against the outer face of the wall. The chute has a rectangular or other opening -t at its outer end which is normally closed by closures or door sections designated generA ally by B and C respectively, operatively connected with each other and mounted on the casing of the chute in such a manner that they open or close simultaneously, the

lower section C forming a hopper, while the upper section may serve as a shield for preventing coal, wood or other articles from striking the wall above the chute and marring the same, as when the sections are in open position, as shown in Fig. 2.

The upper section B is preferably a rectangular frame 5 having an opening 6 that is closed by a glass or other transparent `plate 7, the frame i5 being of such size as to substantially cover half the outer end of the chute. Arranged within the chute are bearing blocks 8 fitted against the top and end walls 9 and 10 of the casing and secured to the latterl by screws or other fastenings 11, the said bearing blocks projecting forwardly lout of the chute. These projecting' ends form lugs which are apertured to receive horizontal pintles 12 that are carried by lugs 13 formedbn the upper door section frame 5, so that the said door section will be suspended from the top. On the ends of the door section are inwardly laterally-projecting ears 14 to which are connected links 15 disposed in close proximity to the end walls of the casing so as to be out of the way of the articles delivered through the chute, the said links being connected with the lower door section so that the two sections will move together.

The lower door section C consists of a plate 16 so proportioned as to close the space left uncovered by the upper door section, and this plate is pivoted at its bottom to the casing A by means of U-shaped clips 17 fastened in upstanding lugs 1S at the lower corners of the casing A, the said clips enconnected by pivots 21 to the rear extremities of the arms 2O to swing the lower door outwardly and downwardly as the upper door section is swung outwardly and upwardly. Adjacent the front end of the casing A and arranged on the end wallsl() thereof are inwardly-extending projections 22 constituting stops with which the arms 20 engage for limiting the opening movement of the door sections, the projections being located in such position as to engage the bottom of the upper doo-r section when in closed position so as to limit the inward or closing movement of the door sections. When the lower door section is opened, the plate 16 will be approximately in the same plane with the bottom 23 of the chute casing so as to form a continuation thereof, as shown in Fig; 2. The weight of the lower door section will be such as to maintain the upper door section in raised position above the chute so as to protect the wall from damage and also conduct the articles that might strike the upper section, into the chute. In other words, the upper and lower door sections constitute an inwardly-contracting mouth for the chute.

In order to prevent breakage of the glass plate 7, the frame 5 ofthe upper door section is formed with an inwardly-extending flange 24 which has its inner surface undercut to form a channel or seat for the reception of a cord 25 that constitutes a cushion against which the glass plate bears, the glass plate being secured in place by clamping members 26 that are secured to the frame 5 by bolts 27. By this arrangement, the glass plate is prevented from being broken by jars or ordinary shocks. The glass plate is protected by a shutter 2S in the form of a metal plate which has its normally lower edge formed into a bead 29 through which passes a pintle rod 30 mounted in `lugs 31 on the rear side of the frame 5.

This swinging shutter or protecting plate is held in closed position by turn buttons 32 pivoted on screws 33 fastened to the frame 5. When delivering articles through the chute, the shutter will be held in closed position as shown in Fig. 2, so as to prevent articles from striking the glass plate and breaking the same. When the door sections are closed .and it is desired to admit light to the cellar or basement, the shutter can be opened by releasing the turn buttons 32, whereupon the shutter swings inwardly and downwardly.

A locking means is provided for fastening the door sections in closed position. In the present instance, the locking means consists of a swinging latch 34 having its extremi ties formed into eyes 35 which engage the extremities of the pintle rod 30, the said extremities project-ing laterally from the lugs 31 on the frame 5, as clearly shown in Figs. 3 and 4. This latch has terminal projections 36 so arranged as to engage behind the stops 22 on the casing A of the chute, the rear or inner surfaces 37 of these stops being beveled as shown in Figs. 1, 2 and 7, so that the latch will have a positive locking engagement therewith. The weight of the latch will maintain the projections 36 in engagement with the stop, and while thus engaged, the upper door section will bear against the front sides of the stops, so that it is impossible to open the upper section and thereby the lower door section. In order to release the latch, it is merely necessary to swing the same upwardly on its hinges so as to disengage the projections 36 thereof from the stops, whereupon the door sections can be swung open, the latch being permitted to hang loosely on the upper door section when in open position. The lower edge of the frame 5 is formed with an outwardly and downwardly curved iiange which laps over the upper edge of the lower door section to form means for shedding the water and also to constitute a convenient means for gripping the door section in opening the same.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are within the scope of the claims appended hereto.

So far as I am aware, I am the first to provide a door for coal chutes composed of two sections which are mounted so as to swing in opposite directions, one upwardly above. the plane of the chute and the other downwardly to a point where it forms a continuation of the chute casing, the upper door sect-ion being provided with a glass plate, wherebv when the door sections are in their normally closed position, the glass plate permits light to enter the chute and thus the interior is illuminated.

Looeie Having thus described the invention, what I claim .is new, and desire to secure by Letters Patent, is

l.
