JOHN B. HOWAT, OF SHARON, PENNSYLVANIA, ASSIGNOR TO SHARON HARDWAE MANUFACTURING COMPANY, OF SHARON, PENNSYLVANIA, A CORPORATION.
DOOR-HANGER IVICHANISIVI.
Application led December 6, 1918.
To all whom 'it may concern.'
Be it known that I, JOHN B. Hownr, a citizen of the United States, residing at Sharon, county of Mercer, and State of Pennsylvania, have invented certain new and useful Improvements in Door-Hanger Mechanism, of which l do declare the following to be a full, clear, and exact description, reference being had to the accompanying drawing, forming a part. of this specification.
The present invention has relation to that class of door hangerme'chanism more particularly designed for use uponY doors formed of a plurality of folding sections, the hanger mechanism serving to aid in sustaining and to guide, by means of the overhead track and trolley, the door sections as they are opened and closed. An example of this type of door hanger mechanism is illustrated in United States Letters Patent No. 1,243,499, granted to the Sharon Hardware Manufacturing Company as assignee of lV. D. Ferris, October 16, 1917.
The present invention consists in the features of novelty hereinafter described, illustrated in the accompanying drawing and particularly pointed out in the claims at the end of this specification.
Figure 1 is a front view showing right and left double doors equipped with my invention, the door sections at the left being` shown in open position and the door sections at the right being shown inclosed position. Figure 2 is a view in -vertical section upon an enlarged scale on line 2-2 of Fig. 1.
i Figure 3 is a detail plan lview of the connecting bar, the connecting link, ythe pivot pin and anti-friction roller, parts being also `shown .in section. Figure L is a plan view showing the left hand double door` with connecting bar and connecting link and showing-.the door partially opened. A designates the'wall of abuilding in whichthe door opening c is formed and B denotes a straight tubular track that is attached to the building wall and extends across the opening of the doorway, this tubular track being suitably supported, as by brackets Z). Each of the double doors C and D is formed o-f two sections hinged together, the inner section of each double door being suitably connected by hinges 5 to the building wall. Each of the inner sections of the doors is preferably provided with suitable Serial No. 265,505.
handles 6 whereby the doors may be manipulated. The top of each of the inner door sections has fastened thereto a connecting bar 8, which has an outwardly extending or offset portion 9 (see Fig.i2), the top and bottom of this offset portion 9 being perforated to receive the pivot pin 10, as most clearly shown in Fig. 2 of the drawing. This pivot pin 10 has its outer end preferably bent inwardly and downwardly, as at 11, for a purpose to be presently stated. Within the offset portion 9 of the connecting bar 8 is arranged the outer en d of the connecting link` 15, this outer end of the connecting link being preferably bifurcatedy and ,i
formed with vertical holes to receive the pivot pin 10. My purpose in forming the connecting link 15 with the outer bifurcated end is to permit an anti-friction roller 16 to be conveniently carried between the bifur` cated ends of the link, this roller being mounted upon the pivot pin 10. t is not essential that this roller 16 should be used under all circumstances, although under certain conditions its use is desirable, andY obviously when the roller is not employed, the outer .end of the link 10 need not be bifurcated. The link 15 is preferably formed as shown, its outer end fitting between the top and bottom portions of the offset part 9 ofA the connecting bar 8, as clearly shown in Fig. 2, as by this arrangement an extremely stable connection is afforded between the bular track B, the bottom of this track AB being slotted from end to end to permit the passage of the bolt 18 therethrough. The threaded portion of the .bolt 18 is provided with nuts 20 and 21 tol hold the bolt in proper relation to the connecting link 15.
When the double doors are in the closed position, as indicated at the right hand side of Fig. 1 of the drawing, the connecting link 15 will extend towards the outer edge of the door opening, so that when the door is' in such closed position, there is no danger of interference of the links 15 or the trolleys 19 by which the double doors are sustained.
As the door (for eXample the door D) is moved from closed to open position (which will be effected by the attendant grasping the handles 6 and pulling outward), the sections of the door will swing outwardly, as indicated in Fig. t of the drawing, hinging with respect to each other at their abutting edges and turning also on the hinges 5. As the sections of the door D are thus swung outwardly and towards the hinges 5, the outer end of the connecting link 15 will swing outwardly, its inner end pivoting upon the bolt 18 depending from the trolley 19. The trolley 19 will move freely along its track until the. door D is completely opened, at which time the parts will occupy positions corresponding to the position of the parts shown at the left hand side of Fig. 1 of the drawings. That is to say, the sections of the double door will be folded against each other and against the front wall of the building and the trolley will be at the end of the track B.
By reference to Figs. 2, 3 and 4; of the drawing, it will be seen that the downwardly turned end 11 of the pivot pin 10 crosses the inner edge of the upper plate of the offset portion 9 of the connecting bar S, and the purpose of this downwardly turned end 11 of the pivot pin lO is to act as a stop and limit the extent to which the connecting link 15 may be swung with respect to the connecting bar 8. By this reference to Figs. 3 and 4i of the drawing, it will te seen that when the connecting bar 8 is moved outwardly and the. link 15 turned to the position shown in Fig. e* in the act of opening the door, the link 15 will contact with the downwardly turned portion of the pivot pin 11 and this will prevent the link 15 from swinging further towards the inner edge `of the door. By reference to Fig. 1 of the drawing, it will be seen that if the connecting link 15 at the top` of the door C were allowed to swing to the left hand side of the connecting bar S, then when the doors were closed the trolleys 19 would cross the center of the doorway and would necessarily interfere and prevent the closing of the doors.
As the doors are manipulated in opening and closing them, the anti-friction roller 16 will contact with that partl of the building wall immediately above the door opening (or a suitable track plate placed at such point) and will prevent the marring of the wall andadd to the ease vof movement of the door.
YBy reference to Patent No. 1,243,499 hereinbefore mentioned, it will be seen that the connecting bar fastened to the top of the double door is united to the connecting link by a headed pin and in such construction, the connecting bar is not extended upwardly and inwardly to form a double bearing for the pivot pin. In my present construction, such double bearing is provided and a much more stable connection between the connecting bar and connecting link is aorded. By arranging the connecting bar to extend across the outer end of the connecting link, it will in no wise interfere with the free movement of the link. This construction is particularly advantageous in preventing the sagging of heavy doors.
It will be understood that the precise details of construction above set out may be varied without departing from the spirit of the invention and that features of the invention may be employed without its adoption as an entirety.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is- 1. In a door structure, the combination with a track and a trolley mounted thereon, of a connecting link pivoted at its inner end to said trolley, a connecting bar adapted to be attached to the door and to project above the upper edge thereof, said connecting bar extending outside of and over the outer end of said link, and a pivot pin extending inside of said connecting bar and through the outer end of said link, said pivot pin having a downwardly extended upper end adapted to engage the connecting bar and to limit the swinging movement of the connecting link.
2. In a door structure, the combination with a track and a trolley mounted thereon, of a connecting link pivoted at its inner end to said trolley, a connecting bar adapted to be attached to the door and pivotally connected to the outer end of the connecting-l link, and an anti-friction roller mounted at the outer end of said connecting link.
3. In a door structure, the combination with a track and a trolley mounted thereon,
of a connecting link pivoted at its inner end'f to said trolley and having its outer end bifurcated, an anti-friction roller mounted at the outer end of said link, a connecting bar adaptedto be attached to the door, said connecting bar extending outside of and?? across the outer end of said link, and a pivot pin uniting the outer end of said link to the connecting bar.
