COAL-CHUTE DOOR.
Specification of Letters Patent.
Patented July 215', rare.
Application filed August 26, 1915. Serial No. 47,549.
To all whom it may concern:
Be it known that I, ALLEN A. Bowsnn, a citizen of the United States, residing at Fort Wayne, in the county of Allen and State of Indiana, have invented a certain new and useful Improvement in Coal-Chute Doors, of which the following'is a specification.
This invention relates to doors for coal chutes such as are used for admitting coal through the walls of cellars and like storage places.
The invention consists substantially of the combination and arrangement of parts hereinafter described, illustrated in the accompanying drawings, and more particularly set forth in the appended claims.
In the drawings-Figure 1 is a front elevation of a coal chute door provided with the present invention. Fig. 2 is a vertical sectional view on line 22 of Fig. 1, showing a portion of a cellar wall provided with a coal chute door made according to-this invention. Fig. 3 is a fragmentary detail view of one of the hinges for the coal chute door.
In the drawing the numeral 1 represents a door frame made of suitable material, such as cast iron, and arranged to be built into a cellar wall shown in section at 2. The door frame extends entirely through the wall, thus providing an opening through which coal is transferred into the cellar or like storage room. Secured to the upper portion of the door frame 1, and extending outwardly therefrom, are two lugs 3 and 4, which carry pintles 5 and 6 on which the door 7 is hinged. The door 7 may be made of any suitable'material, but preferably of cast iron, and carries at its upper edge knuckles 8 and 9. The knuckles8 and 9 are provided with openings for the pintles5 and 6, thus providing a hinged or swinging support for the door 7. Theopening 1O inthe knuckle 9 for the pintle 6 is elongated, as
shown best in Fig. 3, to permit a slight movement of the lug 9 relativeto the pintle carrying member 4 for a purpose to be ,de-
The upper rear portion of the member4 is cut away, forming an opening or notch 11 "which terminates at the forward edge in a shoulder 12. A projection 13' is carried on the knuckle 9 in alinement with the opening 11 of the member 4.. The projection 13 is provided. at its upper rear portion with an overhanging offset 14, arranged to cotiperate with the shoulder 12 on the pintle member 4 when the door is in its upper or open position.
Secured to the lower edge of the door isa latch member 15, which carries a sliding bolt 16 arrc nged to cooperate with an opening 17 1n the lower portion of the door frame to hold the door closed position. The door frame is provided with an oflset or shoulder 18, which extends around the door when closed to prevent any lateral play thereof, Which play, but for this offset, would be permitted by the slotted hinge and allow disengagement of the latch 16. It should be noted that latch is placed on the inside of the door, and arranged to automatically u reaches the position shown in Fig. 3, the
offset shoulder 14 of the projection 13 will register with the opening 11 in the pintle carrying member 4, and the door 7 will then, under the influence of gravity, move slightly downwardly and to the right as shown in Fig. 3, the slot 10 moving on the pintle 6 until the offset shoulder 14 drops in behind the shoulder 12 on the pintle carrying member 4. It will be obvious that when the hinge assumes this position, the door will be automaticallylocked open as shown in Fig. 8. When it is desired again to close the door a slight lift in an upward direction will raise the offset shoulder 14 out of the notch 11, and disengage it from the shoulder 12 of the pintle member, and leave it free to swing downwardly into closed position. As will be seen from Fig. 2, the elongated slot 10 would, of itself, permit thedoor, when H closed, to be raised slightly, and make it possible to release the latch 16 from the opening 17. This is prevented,however, by the fact'th'atthe surface 19 of the oflset member 14 would strike the periphery 20 of the 'pintle carrying member 4, andalso by the fact that the door, when closed, fits'into' the offset 18 of the door frame 1, thus preventing any movement ofthe door relative to the frame.
While I have disclosed oneform of my invention, it should be distinctly understood 1. In combination, a vertically'swinging,
coal chute door, a hinge for said door hav ing the parts thereof connected for pivotal movement relative to one another and for relative movement transverse to the axis of said pivotal movement, interlocking members secured to the parts of said hinge and arranged to be moved into cooperative position by the weight of said door when said door is in its upper or open position to retain said door in said position, and means for preventing said movement of the parts of said hinge relative to one another transverse to the axis of said pivotal movement when said door is in its closed position.
2. In combination, a door frame, a pair of pintle carrying members mounted on said frame, a door having a pair of knuckles pivotally supported by said pintle carrying members for movement about a horizontal axis, interlocking devices on one of said knuckles, and pintle carrying members ar ranged to be automatically moved into cooperative relation to one another by the weight of said door when said door is raised to its open position for holding said door in said position, and means for preventing movement of said door'transverse to the axis of the pivotal movement thereof when in its closed position.
3. In a device of the character described, a vertically swinging door, a hinge for said door having a horizontal pivot and two relatively movable parts secured together by said pivot, one of said parts being provided with an elongated slot to permit lateral movement thereof relative to said pivot, interlocking shoulders carried by said parts and arranged to be automatically moved under the weight of said door by the lateral movement of said parts relative to one another into position to hold said door from closing when it has been raised to open position and means for preventing movement of said door in the direction of said slot when said door is closed.
4., A coal chute door comprising a door frame, a door pivotally mounted on said frame for movement about a horizontal axis, a hinge for securing said door to said frame provided with two parts having a pinand slot connection to permit lateral movement of said parts, interlocking members for preventing pivotal movement of said door on. said hmge and arranged to be moved into or out of operative relation by the lateral movement of the parts of said hinge relative to one another-when said door is open, and
means for preventing lateral movement of the parts of said hinge relatlve to one another in the direction of the slot of said pin and slot connection when said door is closed.
5. In combination, a door frame, a pintlecarrying member secured to the upper portion of said frame, a door for said frame having a knuckle secured to its upper edge, a loose motion pivotal connection between said pintle-carrying member and said knuckle arranged to permit vertical swinging opening and closing movement of said door and also lateral movement thereof relative to said frame, interlocking members on said knuckle and pintle-carrying members arranged to be moved into contact with one another by said lateral movement to lock said door in open position, a latch forholding said door in closed relation with said frame, and means on said frame arranged, when said door is in closed position, to prevent lateral movement of said door and knuckle relative to said frame and pintlecarrying member transverse to the axis of I ber extending into said slot and forming a loose motion pivotal connection between said door and frame, an upwardly extending shoulder on said pintle-carrying member, and a catch member on said lmuckle arranged to slide over said shoulder as said door is opened to raise said door and move the slot in said knuckle relative to said pintle and to automatically drop under the weight of said door behind said shoulder to lock said door open when said door has reached its uppermost position.
7. The combination with an upright frame for acoal chute door, of a pintle member secured to the upper portion of said frame and havmg a horizontal pintle carried thereby, a door for said frame having a lmuckle 1 provided with an elongated slot mounted on said pintle and arranged with its longitudinal axis approximately parallel with the plane of said door, a cam on said pintle member having a surface arranged to curve 1 upwardly and outwardly from the axis of said pintle, and a stop on said knuckle arranged to cooperate with said cam when said door is swung upwardly to slide said slot on said pintle and force the door upwardly in a direction transversely to the axis of said pintle, said cam and stop being shaped to permit said door when raised to its extreme vupper position to fall by its own weight in the direction of the axis of said slot to move said cam and stop into interlocking position to prevent closing of said door.
8. The combination with an upright frame for a coal chute door, of a pintle member secured to the upper portion of said frame and having a horizontal pintle carried thereby, a door for said frame having a knuckle provided with an elongated slot mounted on said pintle and arranged with its longitudinal axis approximately parallel with the plane of said door, a cam on said pintle member having a surface arranged to curve upwardly and outwardly from the axis of said pintle, a stop on said knuckle arranged to cooperate with said cam when said door isswung upwardly to slide said slot on said pintle and force the door upwardly in a direction transversely to the axis of said pintle, said cam and stop being shaped to Copies of this patent may be obtained for permit said door when raised to its extreme upper position to fall by its own weight in the direction of the axis of said slot to move said cam and stop into interlocking position to prevent closing of said door, a flange on said frame arranged to cooperate with said door when closed to prevent movement of said slot transversely to the axis of said pintle, and a latch inaccessible from the interior of said door for holding said door closed.
