DOOR OPERATING AND CLOSING MECHANISM.

Specification of Letters Patent.

Fatented Aug. 31 1915.

Application filed December 18, 1914. Serial No. 877,952.

To all whom it may concern 7 Be it known that I, [ARTHUR P. FnLsBERG, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Door Operating and Closing Mechanism; and I do hereby 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 characters of reference marked thereon, which form a part of this specification.

This invention relates, generally, to improvements in heat-regulating devices; and, the present invention has reference, more particularly, to a novel mechanical -means for variously permitting the retention of the furnace door of a furnace orheater in its open relation, but being under the control of a time-operated device, preferably of the character set forth in Letters-Patent No. 1,103,57d, granted to myself July 14th, 191 f, for automatically releasing at a pre-determined time the said door-closing means to automatically close the said furnace-door.

The invention has for its principal object to provide a novel and simply constructed mechanical door-operating means, controlled as above-stated by a time-operated device, which can readily be applied in its operative position upon a heater or furnace, the parts of which can be variously set so that the furnace-door can be retained in various open relations to the heater or furnace, as may be desired, and which mechanism when re leased operates most effectively to close the furnace-door, when required.

The invention has for its further object to provide amechanical door-closing means of the general character hereinafter more particularly set forth, the mechanism comprising a spring-actuated and controlled rotatable stud, and means for variously setting a releasing arm, as well as a door-closing lever separably connected with the said rotatable stud, the said door-closing lever being also adapted for setting said releasing arm, and as an auxiliary means for varying the tension of the spring which is connected with the stud,'so that the door-operating and closing mechanism is applicable to doors ating and closing mechanism hereinafter set forth; and, the invention consists, furthermore, in the novel arrangements and combinations of the various devices and parts, as well as in the details of the construction of the said parts, all of which will be more fully described in detail in the following specification, and then finally embodied in the clauses of the claim which is appended thereto and which forms an essential part of the said specification.

The invention is clearly illustrated in the accompanying drawings, in which 2-- Figure l is fragmentary front elevation of a furnace and the fire-door hinged thereto and shown in its closed relation, said view illustrating in connection therewith and shown in front elevation a door-operating and closing mechanism made according to and embodying the principles of the present invention, the various parts of the said mechanism being represented in their normal initial positions with relation to each other after the furnace-door has been closed; and Fig. 2 is a horizontal sectional representation of said portions of the furnace and closed furnace-door, and a plan or top view of the said door-operating and closing mechanism illustrated in said Fig. 1. Fig. 3 is a similar view of the said devices and parts shown in said Fig. 2, but illustrating the furnace-door in an open position, and the said door-opening and closing mechanism set to close the door when released by a time-operated device. Fig. 4 is an elevation of the door-operating and closing mechanism, looking in the direction of the arrow at in said Fig. 2, with the door and furnace-portion omitted from said view, the parts of the mechanism being represented in their normal initial positions ready for setting; and Fig. 5 is a similar elevation of the saidmechanism with the setting arm represented in its raised and released relation to the remaining parts of the mechanism. Fig. 6 is a plan view of the setting arm shown in its detached relation from the remaining portions of the door-operating and closing mechanism. I p v Similar characters of reference are employed in all of the said above described views, to indicate corresponding parts.

Referring now to the said figures of the drawings, the referencecharacter 1 indicates a fragmentary portion of any suitable furnace or heater, and 2 indicates one of its usual hinge-lugs, with which is pivotally connected by means of a pm or bolt, as 3, one of the hinge-lugs 5 of the furnace-door 4.

The herein-above mentioned door-operating and closing mechanism, showing one embodiment of the principles of the present invention consists, essentially, of a plate-like upright, as 6, from which extend in lateral directions a pair of lugs or supports 7 and 8. The said lower lug or support 7 is provided with an upwardly extending stud 9, and the upper lug or support 8 is made with a suitable perforation which forms a bearing in which is rotatably mounted a short spindle or stud 10. The upper portion of said spindle or stud 10 projects for some distance above the upper face of said lug or support 8, said upwardly projecting portion of the said spindle or stud being of hexagonal or other suitably formed configuration, as shown in Figs. 2 and 3 of the drawings, and for the purposes to be presently more fully set forth, and the lower cylindrical portion of the said spindle or stud 10 projects below the lower surface of the said bearinglug or support 8, substantially as shown in Fig. 1 of the drawings. Connected with the said bearing-lug or support 8, in any suitable manner, is a segmental element or member, as 11, usually in the form of a quadrant, said element or member being provided upon its upper surface with upwardly projecting ratchet teeth, as 12, also arranged in the arc ofa circle and preferably at the arc-shaped marginal edge of the said segmental element or quadrant 11, substantially in a manner as shown in Figs. 1, 2 and 3 of the drawings. Suitably mounted between the said lugs or supports 7 and 8 with its lower end-portion suitably secured to the upwardly extending stud 9 and its upper end-portion suitably secured to the downwardly projecting portion of the said spindle or stud 10 is a suitable coiled spring 18. That the said plate-like upright 6, and its parts, may be secured in its operative position with relation to the heater or furnace 1 and the furnace-door 2, the said plate-like upright has connected.therewith, and extending therefrom in' a manner illustrated in the several figures of the drawings, a rectangularly shaped and open frame-like structure, as 14, the upper and lower platelike members 15 and 16, are provided with suitable perforationsor holes, as 17 and as indicated in dotted outline in Fig. 1 of the drawings. To positively secure these parts of the mechanism in their operative positions, the pin or bolt 3 is removed, and the hinge-lugs 2 and 5 are sufliciently separated, to permit the said frame-like structure 14 to be slipped upon the hinge-lug 2 so as to embrace the same. The hinge-lug 5 is thereupon placed upon the upper plate-like member 15, and the various parts connected in this assembled relation by the re-insertedpin or bolt 3, as will be evident from an inspection more particularly of Fig. 1 of the drawings. The vertical portion 18 of the said frame-like structure is: suitably provided with a screw-threaded hole forthe reception of a suitable set-screw, as19, the end of which can be screwed against the hingelug 2, so that the frame-like structure will be rigidly secured against accidental displacement in its embracing relation with the said hinge-lug, as will be clearly evident.

The previously-mentioned setting arm, as will be seen from Fig. 6 of the drawings, consists, essentially of two members, 20 and 21, the member 20 having a hexagonal or other polygonally-shaped wrench-like portion 22, adapted to be fitted over the hexagonal or other polygonally-shaped portion of the rotatable spindle or stud 10. Extending laterally from said wrench-like portion 22 are a pair of fingers, as 23 and 24, formed with a space 25 between them. One of the said fingers, as 24, is also provided with a suitably formed and laterally projecting lug, as 26, or other suitable means for providing a stop, and suitably secured to the said fingers 23 and 24, and extending across the space 25, is a pivot-pin 27, upon which is pivotally mounted, so as to swing vertically, the member 21, forming the setting arm of the mechanism. This arm or member 21 is of sufiicient length that its free end-portion can be readily slipped over the ratchet-teeth 12 of the quadrant 11, when moved hori- 1 zontally in one direction, and can be dropped 2 into locked engagement with the desired tooth 12 for set-ting, and to prevent its return to its normal initial position, until disengaged from its retained engagement with the tooth in the manner to be hereinafter more fully described. The said member or arm 21 is also provided in its lower edge with a recess 28 which registers with the stop-lug 26 of the finger 24, to prevent the said member or arm from dropping below the horizontal plane of the quadrant 11, when the parts are in their normal position, before the mechanism is set. In a proper place, and'upon its upper edge,- the said news member or arm 21 may also be provided with a projection or stop-lug, as'29, the purpose of which will be presently described.

In addition to the above described devices and parts, there is also employed a door-engaging arm or lever, as 30, which is provided with a hexagonal or other suitable polygonally-shaped wrench-like end-portion, as 31, adapted to be detachably fitted over the hexagonal or polygonally-shaped end-portion of the previously mentioned spindle or stud 10.

Having in the foregoing described the general arrangement and construction of the various devices and parts of a furnace-dooroperating and closing mechanism illustrating one embodiment of the principles of the present invention, I will now briefly set forth the manner of setting the mechanism, whereby the furnace-door may be retained in its open relation to the furnace, and when the mechanism is released by a time-com trolled device of any suitable construction bringing the furnace-door into its closed relation with the furnace or heater.

During the night, when the fire door of the furnace or heater is to remain open, all that is necessary is to swing the setting-arm or element 21 horizontally in the direction of the arrow w in Fig. 2 of the drawings, causing said arm or element to be brought into retained engagement with any one of the ratchet teeth 12 according to the degree of open relation of the fire-door desired. This movement of the said arm or element 21 produces a rotary movement of the spindle or stud 10, whereby the coiled spring is brought imder tension. The door-engaging arm or lever 30 is then properly connected by means of its portion 31 with the hexagonal or other polygonally shaped end-portion of the spindle or stud 10, with the said lever or arm 30 resting against the face of the door, substantially in the manner shown in Fig. 3 of the drawings. The ring or link 32 of the usual chain 33 leading to and connected with the time-controlled diaphragm-rod of the furnace or heater, adapted to be released by a time set clock, is then inserted over the free endportion of said setting element or arm 21,

as indicated in said Fig. 3 of the drawings, the said chain being held in its position by contact of the said link or ring 32 with the stop-lug 29, as shown, and without, however, lifting the element or arm from its retaining engagement with the ratchet-tooth 12. In the morning, at the previously determined time, when the time-set clock releases the diaphragm-rod, in the manner of my said former Letters-Patent No. 1,103,574, and raises the end of the diaphragm-rod to which said chain is attached, the consequent pull upon the chain will lift the element or arm into the position, indicated in Fig.

o of the drawings, out of its retaining engagement, thus immediately allowing the coils of the spring 13 to act, and cause the spring to assume its normal position at rest. The rotatable returning movement of the spindle or stud 10, simultaneously returns the members 20 and 21, and the lever or arm 30 from their relative positions, indicated in Fig. 3 of the drawings to their normal initial positions represented in Figs. 1 and 2 of the drawings, the returning movement of the lever or arm 30, on account of its action upon'the outer face of the fire-door 4, also returning said door into its closed relation with the heater or furnace, as will be clearly evident.

With large and heavy furnace-doors it may be necessary to increase the tension of the spring 13. This is readily accomplished, without opening the fire-door 4, by taking hold of the lever or arm 30 and moving it in the direction of the arrow 3 in Fig. 3 of the drawings, and thereby likewise rotating the spindle or stud 10' and bringing the setting member or arm 21 into retained engagement with any one of the ratchet-teeth 12 that may be desired, thus partially winding the spring 13 and bringing its coils under the necessary tension. The lever or arm 30 which now stands, say in the position represented in Fig. 3 of the drawings, is now removed from the polygonal portion of the spindle or stud 12 and-then replaced upon said portion of the spindle or stud so that it will stand in the position shown in Fig. 2 of the drawings, resting directly against the face of the closed fire-door 4. WVhen the door 4 is opened for the night, the swinging action of the door against the lever or arm 30 will still further move the setting element or arm 21 into another ratchet tooth 12 to be held thereby, and whereby the tension of the spring 13 is still further increased. The chain 33 is then applied to said element or arm 21 in the manner and for the purposes herein-above described.

My novel form of furnace-door operating and closing mechanism may be readily applied to any suitable furnace, heater, boiler, and the like, and with slight changes and modifications may be used with any suitable construction of time-controlled damper-regulating and door-controlling devices for such furnaces, heaters, and the like, without departing from the principles of the present invention.

I am fully aware, that changes may be made in the general arrangements and combinations of the various devices and parts, as well as in the details of the construction of the said parts, without departing from the scope of the present invention as set forth in the foregoing specification, and as defined in the clauses of the claim which is appended thereto. Hence, I do not limit my invention to the exact arrangementsand combinations of the said various devibes and partsa described in the said specification, nor do I confine myself to the eXact'det-ails of the construction of the said'parts, 'as'illu's trated in the accompanying drawings. vl I claim: Y I I l 7 1.
