DANIEL BBUHN, 0F HAMMOND, INDIANA.

COAL-CHUTE.

To all whom it may concern:

Be it known that I, DANIEL. BRUHN, a citizen of the United States, residing at Hammond, Lake county, Indiana, have invented certain new and useful Improvements in- Coal-Chutes, of which the following is a specification.

My invention relates to so called coal chutes which are in the form of an iron frame which is inserted in anopening in a basement wall and is provided with a cover, door or closer which may be opened only from within and which door may also, when desired, contain a heavy glass which makes itserve as a window when not in service as a coal chute.

For practical purposes the questions of simplicity of construction and even a small reduction in cost are important in connection with these structures owing to the quantities of same that are being used.

The objects of the present invention are to reduce the weight,the amount of metal required and the number of parts, and to obviate the use of pivot lugs, friction-parts and the like at comparatively vital points in the construction, so as to make the chute comparatively light in handling and shipment, simple in the matter of installation, and comparatively free from the liability of derangement.

With these objects in view the invention consists in the novel construction, combination and arrangement of parts hereinafter described in detail, illustrated in the accompanying drawing and incorporated in the appended claims.

In the drawing-Figure 1 is a vertical section through the chute and a section of building wall into which the chute has been inserted. Fig. 2 is a similar view showing the door open and is substantially a section taken on line22 of Fig. 8. Fig. 3 is a perspective view ofthe chute alone, open. Fig. 4 is a broken away detail view.- Fig. 5 is an enlarged section taken substantially on line 55 of Fig. 1.

In the several views 2 represents the wall of a building in which has been made an opening 3 for the reception of the chute which consists of a rectangular, box-like framed having flanges 5, 6, 7 and 8 which Speeificationof Letters Patent."

serve as a frame around-the. chute-opening as seenfrom-the outside of .the building.

In the front portion of this openingor of the. frame 4 is pivoted the door 9. to'which are riveted segmental plates 10 and 11 which form sides for that portion of the chute which projects beyondthe exterior of the building when the chute is open-as inFigs. 2and3. p U I As showniin Fig. 1 the'door 9, when closed, is arranged to be within the vertical plane of the wall and of theopening frame consisting of the flanges 5, 6', 7 and 8, which prevents water running downthe outer face of the wall from-entering within the chute. At the lower side of the opening under the door the frame portion, 6 is provided with an inclined sill portion 12 which is formed with an upward bulge,ridge5or bead 13 which extends above the lower edge of the door at its rear side and serves to prevent water running down the door from entering the inclined chute portion lhof the frame 4. At its lower edge the door 9 is provided with a stiffening rib 15 the ends of which are bent over to form substantially round trunnions 16 and 17 which are journaled in openings 18 and 19in the sides. of the frame 4:, said rib 15, as shown in Fig. 4:, beinghalf round in cross section and riveted to the door. A simple form of wall shield that is inexpensive .andmounted to insure strength and permanency is provided in a plain rectangular plate of metal which is formed with lugs bent into loops or eyes 21 and 22 that rotatably engage a fixed rod 23 riveted at its ends 24: and 25 into bores in the sides 10 and 11 into which said'ends fit snugly. This plain rod mounted in this fixed manner obviates the usual unstable mountings for these shields and obviates the need of special dies and parts which. are not even if these studs should accidentally be broken off that would not in the least incapacitate or disarrange the chute for working purposes, the construction being designed throughout to obviate liability to accidental breakage in any of the vital parts such as the mounting ofthe door, its pivotal supports and the pivotal supports for the shield 20 designed to protect the wall of the building when coal is thrown into the chute. The lug or pin 27 is also used as a part of a simple latch arrangement for locking the door shut against being opened from the outside. On one of the vertical sides of the frame 4 is secured in any suitable manner, as by rivets 28 and 29, a bearing bar 30 on which is pivoted or fulcrumed at 31 a lever or handle 32 in which is formed a notch 33 adapted to engage the pin or stud 27 the moment the door is in its vertical or closed position as in Fig. 1. This lever is provided with an incline or beveled portion 34 against which a stud 34 strikes in its rearward movement, thus raising the handle or lever so that it may be engaged with said pin. The release to open the door is efiected by simply raising the handle and pushing against the door from its rear or inside.

From the outer face of each side 10 and 11 projects a stud 34 for which there is room between said sides and the ends of the frame 4 to substantially the extent of the thickness shown in Fig. 5 of a narrow inturned flange 35 formed on each of the flanges 7 and 8. This flange 35 is in each instance secured to 4 in Fig. 5, and side views of it are shown by dotted lines in Figs. 1 and 3 and partly in full lines in Figs. 2 and 4. The vertical edges where the leader lines. from 35, 35 in Fig. 5 strike also constitute stops for the stud or pin 34, thus simplifying the construction by doing away with special parts for that purpose. On the other hand, as will more fully appear hereinafter the stud 34 serves the dual purpose of a stop on 10 or 11 engaging the flange 35 to limit the outward drop or opening movement, as well as a part to be engaged by a latch to prevent opening of the door from the outside, the purpose being to so coiirdinate and arrange the parts as to eliminate the cumbersomeness, expensiveness, lack of neatness, and complexity prevalent in devices heretofore produced for this purpose. This flange 35 serves as a stop for the pin 34 and limits the outward drop of the door, and as in the other features of construction the flange is made to serve not only as the fastening means for the face flange 8 orpart of the outer frame but as a practicably indestructible stop for the pin 34 which may be firmly and also unbreakably riveted into the side of the movable portion of the chute forming a part of the door. As the pin 34 is between the side 1.0 or 11 and the vertical side of the frame 4 it offers no obstruction within the chute and is not exposed to breakage by coal being thrown against it. On the lower edge of the frame portion 5 is a pair of lugs 36 and 37 against which the upper edge of the door rests in its closed position and on the bar 30 is a lug 38 which limits the downward movement of the lever 32.

Having thus described my invention 1 claim as new and desire to secure by Letters Patent 1. In a coal chute, a frame adapted to be inserted in a wall-opening, a door having segmental sides secured thereto and forming the sides of the outwardly projecting portion of the chute when open, and a stifiening rib having a fiat side riveted to said door the ends of which are bent upon themselves and form trunnions which are revolubly mounted, in the sides of said frame.
