JOHN EDWARD OGDEN, OF BROOKLYN, NEW YORK, ASSIGNOR TO THE PATENT APPLI- ANCE COMPANY, A CORPORATION-OF NEW YORK.
Specification of Letters Patent;
Patented Oct. 25', 1910.
Application filed May 2 0, 1910. Seriallo. 562,378.
To all whom it may concern:
Be it known that I, J OHN EDWARD OGDEN, a citizen of the United States of America, and a resident of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Doors and Means for Operating the Same, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.
My invention relates to improvements in doors and means for operating the same, and particularly to that class of doors commonly employed in freight sheds, steamshi docks,
factories, and the like, where large oorway openings are required.v
The main objects of my invention are to reduce 'the space through which a door of this description shall pass in its opening and closing movement, to facilitate the opening and closing thereof, to provide for the convenient partial opening of such doors, and generally to, improve and simplify the construction of doors of this character and the means for'operating them.
In carrying out my invention I construct the door in two parts, an upper and a lower part, the lower part being arranged to slide with respect to the up er part, the lower ends of the two parts eing thereafter arranged to move upward simultaneously in right lines while theupper edges thereof swing outward under the influence of swinging suspension elements pivotally connected thereto and to the doorway framing. My invention also consists in many novel details of construction and combinations of parts as will be fully pointed .out'herein-- after, and in order that my invention may be fully understood, I will now proceed to describe an embodimentv thereof, having reference to the accompanyin trating the same, and will t en point out the novel features in claims.
In the drawings: Figure 1 is a View in front elevation of a door and door operating mechanism constructed in accordance with my invention, the door being shown 1n its fully closed position. Fig". 2 is a view in central vertical transverse section. there through, the door being shown in. full lines in its closed position and in dotted lines in its fully opened position. Fig. 3 is a simi- I lar view showing the door as in its half-way drawings illusopen position. Fig. 4 is a view in horizon.- tal section substantially upon the line 44 of Fig. 1. Fig. 5 is a view in vertical transverse section of a door constructed in accordance with my invention showing a modified form of the supplemental supporting means employed, the door in this instance being shown as in its fully opened position.
The door, as a whole, comprises two sections,-an upper main swinging section 10, and a lower sliding auxiliary section 11. The door sections are arranged to close a doorway formed in a framing 12. The upper or main door section is suspended from the doorway. framing by means of suspension elements convenlently comprising links 13 which are pivotally connected to the doorway framing at their upper ends 14, at points substantially in line with the upper end of the door, and at their lower ends at 15 to way framing. The lower or auxiliary sec-' tion 11 is mounted to slide in guideways 17 'at the front side edges of the upper main door section, the side edges of the said lower section having portions 18 constituting slides which are fitted to the said guideways 17.
'At its lower extremity the said auxiliary door section is provided with laterally extending pins or trunnions. 19 which are received in vertical guideways 20 formed in the side of the doorway framing. Lifting chains 21 are also connected to these pins, the said lifting chains passing over an overhead drum22 to which the opposite ends of these chains are attached and upon which the said chains are arranged to be wound as the drum is rotated. Suitable means is provided for rotating the said drum, and a counterbalancing weight 23 is also provided, the chain 24: thereof beingalso conveniently wound around the said drum whereby the said weight will, in the operation of the door, tend to counterbalance its we' ht. The drum 22 may be rotated to open or c ose the .door by any suitable means, a simple endless chain hanging from a sprocket wheel ing the'eifect of merely lifting the lower auxiliary door section with respect to the upper door section. This lower. door section be lifted to any desired hei ht, up to may point where it is substant1a y upon a the level with the main door section v10. The
two door sections are preferably of. about the same height so that when the door section 11 is lifted to such a level the upper and lower ends thereof will come just about level with the upper and lower ends of the main door section 10, and the entire lower half of the doorway will be open. When the lower door section reaches its uppermost position some portion thereof will be arranged to come into abutting relation with some portion of the upper door section so that it can be moved no farther with respect thereto. Conveniently the trunnions 19 may abut against the lower end of the guide portions 17 of the upper door for this purpose. Thereafter, a continued rotation of the drum 22 will have the effect of lifting the lower end of both the door sections simultaneously, the upper ends being at this guided outward by the links 13. The two door sections will, of course, move as a unit, and the disposition and arrangement of the suspension elements 13 is such that the upper ends thereof will move outward in substantially a horizontal line. The lifting of the lower end of the door sections will cause the door to draw away from the guides 16 so as to free it therefrom, the trunnions 19 being retained however in the guideways 20 so that they act as a vertical guide for the lower end of the door while at the same time permitting the upper end of the door to swing outward under the influence of the suspension elements.
As the door approaches a horizontal position the lower end of the door sections will approach the upper pivotal points 1 of the suspension elements and the door will begin to lose the support of the said suspension elements. For this reason I have provided a supplemental supporting means for supporting the upper and outer edges of the door sections at this time, the same conveniently comprising a rigid support in the form shown in Figs. 2 and 3, or a flexible A chain connection 28 in the form shown n I Fig. 5. In its complete horizontal" position the door will conveniently lie in a positipn substantially parallel with the said suspension elements as is shown in dotted lines in Fig. 2 and in full lines in Fig. 5, and at this time the said door will be wholly supported by the lifting chains and the supplemental supporting fore, be seen that at least half the weight of the door, is directly borne by the lifting chains so that wheirit is desired to lower the door it will be only necessary to start to rotate the drum 22 in a direction to unwind the chains and the door will then start to move downward by its own weight.
By the foregoing it will be seen that the door may be opened at least half way without any appreciable space being occupied in the movement thereof, that is 'to say, no part of the 'door will-be caused to project inward or outward. Itwill also be seen that during the completion of the opening from the half open to the full open position but a minimum of space will be occupied by the door, and that the space which is so occupied is space which is ordinarily of little value.
This type of door is especially adapted for steamship docks, freight and warehouse sheds, factories and the like, in that the lower portion of the door can be opened with a minimum of trouble to allow hand trucks to be run in and out (the entire doorway opening bein'g usually twenty feet and upward) without the main door section being opened at all, and that the opening of the auxiliary door section in this manner can be effected while packages, trucks, or the like are occupyingthe space immediately adjacent to the door. Then if it be required to open the door beyond this point the movement of the main and auxiliary door sections together is one that takes place substantially over-head so that even the small space necessary to accomplish the movement is one which is out of the way of the positions objects are likely to occupy in a dock, warehouse, factory, or the like, the space being one which is usually free and clear in any event.
It will also be noted that the arrangement is such that no head room is necessary above the doorway for the operation of the door. The doorway opening can extend substantially up to the ceiling or roof. The over head mechanism shown including the lifting chains, drum, counterbalance weight, etc., may of course, be located in. any convenient position and designed with respect to the place adapted to receive it. In the drawings this is shown somewhat diagrammatically as the precise form, construction, and arrangep ent thereof is no part of the present invenion.
What I claim is:
1. The combination with a doorway framing and a two-part door fitted thereto, one part comprising an upper door section fitted to the upper portion of the said doorway and means 27 or 28. .It will, therethe other a lower door section fitted to the lower portion of the said doorway, the two said door sections being provided with coengaging slides and guideways whereby the lower said door section is guided vertically eraser in right lines over the face of the upper door section, suspension elements constituting swinging supports pivotally' connected to a part stationarywith-the doorway framing and to the-u per door section, means for first lifting the lower door section in right lines from a position substantially beneath the upper door section we position" substantially sideby side therewith and for thereafter lifting the lower ends of both of the said door sections together in substan-' tially right lines to a position substantially neutral with respect to the-said supporting elements, the said elements serving to guide the upper end of the door sections outwardly during such lifting movement, and supplemental means for supporting the outer end of the said deer sections 'a srth'ey approach a neutral position with respectto the said supporting elements and'thereby lose the supvport thereof.
2. The combination with a-doorway'framing having vertical side guides therein, of an upper door section fitted to the upper portion of the said doorway, a lower door section fitted to the lower portion of the said doorway, the said door sections beingprovided with co-engaging slides and guideways for guiding the lower section vertically in right lines over the face of the upper door section, trunnions projecting fromthe lower ends of the lower door section and engaging the vertical side guides of the framing, suspension elements connected to the framing and tothe upper door section, the said upper door section being otherwise free to move except as it is controlledby its engagement with'the lower door sectio nya stationary guidenormally engaging the up per end of the said lower door section but terminating in a point just above the lower end of the said lower door section when it is in its uppermost position, and means consaid doorway, means for first lifting the lower door section in right lines from a position substantially beneath the upper door section, to 'a position substantially side by side therewith, and thereafter for lifting the lower ends of both the door sections to- I gether, suspension elements pivotally connected to the doorway framing and to the said upper door section, the said suspension elements acting to guide the upper ends of the said door sections outward, during the time the lower end'of the said upper door section is being lifted, and supplementals'upportingmeans forsupporting the outer end of the said "door sections, as the said door sections approach a neutral position with respect to the said suspension elements.
The combination with. a doorway framing having vertical side guides therein, of
a door comprising upper and lower sections,
fitted thereto, the said door sections being" provided with co-enga'ging slides and guidesection, and means connected with the lower end of the lower door section to lift the same, the said lower door'section being arranged to reach a lifting engagement with the upper door section, after the lower door section has been lifted to a predetermined extent, whereby, the lower. end of both of aming, suspension elements connected to the framing and to the upper doorthe door sections will be lifted together in the continuance of such lifting movement,
the said suspension elementsacting at such times to guide the upper ends. of the said sections outward, the lower ends of both the said door sections being at such time entirely guided bythe" engagement of the trunmons ofthe lower section with the said vertical guideways. r
5. The'combination with a doorway fram-- ing, of an upper door section fitted to the upper portion of the said doorway, a lower doorsection fitted to the lower portion of the said doorway, means .for first lifting the lower section in right lines'from a position substantially beneath the upper door section, to a position substantially side by side therewith and thereafter for lifting -the gether, suspension elements pivotally connected to the doorway framing at points therein substantially in line with.the upper end of the upper door section when closed, and to the said upper door .Section at points about midwa between the upper and lower edges thereo and supplemental supporting a means for supporting the outer end of the said door as the lower end thereof approachesth'e polnt of pivotal connection of the suspenslon elements with the doorway framing and so loses the support of'the said suspension elements.
In witness whereof'I have hereunto set my hand this 17thday of May, 1910. I JOHN EDWARDOGDEN. Witnesses:
