Ferris, Sterling, Ill., assignor to Frantz Manui'acturing'Ca, Sterling, 111., .a corporation oi’ Illinois Application March 25, 1937, Serial No. ‘132,913 8 Claims. This invention relates to garage doors, or sim ilar doors, and particularly to those that are adapted to open upwardly into an overhead open position. Generally stated, the object of the invention is to provide a novel and improved construction and arrangement whereby a garage door of this general character is constructed and mounted in a way that will more satisfactorily enable it to accommodate itself to varying conditions of door way and building construction. A special object is to provide a novel construc tion and arrangement whereby garage doors of this kind may be used in pairs, say, for a two-car 15 garage, in a manner that will tend to obviate the necessity of using anything between them, inside of the building, that might be quite liable to in juriously engage the sides of the automobiles. Another object is to provide a novel construc 20 tion and arrangement whereby the opening move ment, as well as the closing movement, of the door, is retarded at the end of either movement by friction means that can be easily adjusted or regulated to insure the desired retarding effect, in accordance with the size and weight of any particular door. It is also an object to provide certain details and speci?c features of construction tending to increase the general e?iciency and desirability of 30 a garage door of this particular character. To the foregoing and other useful ends, the invention consists in matters hereinafter set forth and claimed and shown in the accompanying _ drawings in which Fig. 1 is a vertical section of a garage door embodying the principles of the invention, show ing adjacent portions of the building. Fig. 2 is a fragmentary perspective view of cer tain portions of the support upon which the door is mounted for opening and closing movement. Fig. 3 is a perspective of one of the parts shown in Fig. 2 of the drawings. Fig. 4 is a horizontal section on line 4-4 in Fig. 1 of the drawings, on a smaller scale. Fig. 5 is an enlarged vertical detail section on line 5-5 in Fig. 1 of the drawings. Fig. 6 is a side elevation of the parts shown in Fig. 5 of the drawings. Fig. 7 is a diagrammatic view showing certain of the elements of Figs. 5 and 6 in separated condition and in perspective. As thus illustrated, the invention comprises a pair of upright rectangular garage doors I and I, 55 mounted in the two doorways in the front of (CI. 20-16) a the garage building 2, as shown in Figs. 1 and 2 of the drawings. It will be seen that each door is of a width to swing through its doorway, but is preferably of a height to normally engage the top portion 3 of each doorway immediately inside thereof, as ‘shown in Fig. 1 of the drawings, while in this closed position, each door has its lower edge resting upon the floor of the garage. Each door has a pair of upright angle irons 4 secured to the. back or inside thereof, and each angle iron has its rearwardly extending flange formed with a gap at 5, and the horizontal chan nel irons 6 are mounted in these gaps or notches,_ as shown more clearly in Fig. 2 of the drawings. To hold the channel irons 6 for endwise adjust 15 ment in these gaps or notches, guide plates Tare bolted to the rearwardly extending ?anges of the angle irons 4. For each door, there is a horizon tal channel iron 8 bolted to the back or inside of the door, with the adjacent end portions of the channel irons 6 clamped therein by bolts 9 that extend through the doors. The channel irons 8 may have holes or slots for said bolts, and the channel irons 6 may also have bolt holes of this character, whereby the channel irons 6 are ad 25 justable endwise in the channel irons 8, for doors of different widths, or for different distances be tween the sides of the building. The outer end of each channel iron 6 has a right angle channel arm section [0 secured thereto by rivets and 30 plates II, as shown more clearly in Fig. 2 of the drawings, so that these horizontal and parallel arms Ill are rigid with the channel irons 6, and are thereby susceptible of adjustment toward and away from each other, by means of the bolts 9 O: 5. previously described. Each arm ID has a brace Ill extending upwardly from a swivel eye 12 on the arm to an eye 13 on a bracket plate [4 se cured to the back or inner side of the door. Thus, these braces l I I can assume different posi tions, according to the distance between the arms ill, for garage buildings having varying or differ ent structural conditions. Each arm is pivoted on the building at l5, and each arm is preferably provided witha series of holes l6 for adjustably connecting the lower end of a spring I'I thereto, the upper end of each spring being preferably fastened to the building at I8, by any suitable or desired means. _ Thus, each door normally occupies its closed 5 50 position, as shown in Figs. 1 and 4 of the draw ings, but, with the assistance of the springs, may be raised into the position shown in dotted lines in Fig. 1 of the drawings, in which position the 55 2 2,114,419 lower end portion of each door rests against the under side of the top portion 3 of its allotted door way. The Springs help to raise the doors into open position, and then cushion the downward movement of the doors into closed position. When two doors are arranged this way, as close together as possible, something must be provided, in an upright position, between the adjacent arms II, to support the pivots l5 of these arms. If a 10 support of that kind should be vertical, it would then be far enough within the building to en danger the sides of the automobiles. Therefore, to avoid such danger, an inclined ?xed support i9 is provided, which extends upwardly from a point 15 between the adjacent lower corners-of the two doors, to a point above on the building some dis tance back from the front of the building, so that the upper and lower ends of this inclined support are held in ?xed position. This inclined support 20 I! is of advantage, it will be seen, for the reason that it provides clearance below it, at its lower portion, for the wheels and foot-board and mud guards of the vehicles, which are the things on the automobiles that are most likely to be injured 25 by a side swerve in driving the vehicles into and out of the building. Preferably, each pivot I5 is constructed as shown in Figs. 5, 6 and '7 of the drawings, in order to provide a retarding friction at the end 30 of the upward movement of the door into open position, and also at the end of the downward and the disk 21 in unison, so that no friction is exerted during the main portion of the opening movement of the door. However, when the lug ' 39 on the disk 21 strikes the ing 38 previously mentioned, the rotation of the disks 26 and 21 is stopped, and the disk 23 then rotates alone until the ends of the slots 25 engage the bolts 28 previously mentioned, and it is during such ?nal rotation of the disk 23 that su?lcient fric tion is developed between this disk and the disk 21 to retard the end portion of the opening move ment of the door. Thereafter, when it is desired to close the door, all three disks rotate with a swinging motion of the arm l0 until the ing 39 strikes the lug 31 previously mentioned, and 15 then again the disk 23 rotates alone in frictional contact with the disk 26, thereby frictionally re tarding the end portion of the closing movement of the door. Preferably, each disk 21 is provided with another lug 40, diametrically opposite the 20 lug 39, so that the same disks can be used either at the right or the left. In this way, the plates 3| can all be alike, but those at one side will have their lugs 31 and 38 into position to cooperate with the ing 39, while those at the other side of 25 the doorway will be turned around to have their lugs 31 and 38 in position to cooperate with the lug 40 instead. Thus, the pivot of each arm ID has a friction device therein, that develops friction at the end 30 of the opening movement of the door, and at the movement of the door into closed position. For end of the downward or closing movement of the that purpose, each arm I ll has a bracket plate 20 secured thereto, as by means of bolts inserted door, su?lciently to bring the door softly and easily into open position, and softly into closed position, when the friction devices are properly adjusted or regulated to insure the desired or requisite degree of friction necessary for that through holes 2| in said plate, and through the arms. Each plate 20 has a squared hub portion 22, and a metal disk 23, with a su_bstantially rec tangular opening 26, is mounted on said squared portion of the plate, the squared portion extend 40 ing through and substantially ?tting this open ing. This disk 23 is also provided with diametri cally opposite curved slots 25. A disk 26 of as bestos, or other suitable ?brous material, en gages the face of the disk 23, and a cup-shaped 45 or ?anged disk 21 has its inner flat surface arranged to engage the other side of the disk 26, as shown in Fig. 5 of the drawings. Bolts 28 are inserted through all three disks, and through the slots 25, to clamp the three disks together, and 50 by means of these bolts the friction between the disks can be adjusted or regulated to suit the conditions, and in accordance with the weight of the door and the tension of the said springs. The disks 26 and 21 are provided, respectively, 55 with round openings 29 and 36 to receive the hub portion 22, so that these disks 26 and 21 will have rotary movement on said hub, while the disk 23 is held against rotation on said hub and will move in unison with the swinging movement of the arm l0, when the doors are opened and closed. A bracket plate 3| is secured to the building, in rigid and stationary position, for each pivot i5; and for each pivot, there is a stud 32 extending through the bore or opening 313 of the plate 20, 65 formed at its outer end with a head 34, and at its inner end with a reduced portion 35 which ex tends through the opening 36 in said bracket plate, this reduced portion 36 being riveted over to make the stud 32 rigid with said bracket plate. 70 The latter is also provided with outwardly bent lugs 31 and 38, arranged substantially ninety de grees apart, as shown. With this arrangement, when a door is raised into open position, the disk 23 of each pivot turns on the axis of the latter TI and, by frictional contact, rotates the disk 26 purpose. 35 _ This application discloses matter common to that disclosed in copending application to same 40 inventor, Serial #97376, ?led Aug. 26, 1936. What I claim as my invention is: - 1. In a garage door, a single rigid door section normally in vertically disposed position in the doorway of the building, a horizontal arm rigid with and extending at right angles to the back or inside surface of the door, an inclined ?xed support extending upwardly and inwardly of the doorway, from a point adjacent the lower corner of the door, at the front of the building, to a 50 point above and in rear of its lower end, and a pivot for said arm, on said inclined support, the latter providing clearance below its lower portion for the mud-guards and foot-board of an auto mobile, the door thus constructed having a hori zontally disposed overhead open position, when moved upwardly about the axis of said pivot. 2. A structure as speci?ed in claim 1, compris ing another similar door, with a similar rigid arm, the two doors being side by side in the same ver 60 tical plane, and a pivot for the latter on said inclined support, so that the latter is between the two arms, whereby the clearance below said inclined support is eii‘ective for an automobile at either side thereof. ’ 65 3. In a garage door, asingle rigid door sec tion normally occupying a vertically disposed po sition in the doorway of the building, a horizon tal channel iron on the back or inside surface of the door, the length of said channel iron being 70 less than the width of the door, horizontal par allel arms joined to sections of channel iron that are slidable endwise in the channel of said ?rst mentioned channel iron, so that the distance between said arms may be changed, vertically 76 3 2,114,419 disposed angle irons on the back of the door, provided with guiding means for said adjustable sections of channel iron, and pivots for said arms on the structure of the building, whereby the said door has a horizontally disposed over head open position. 4. A structure as speci?ed in claim 3, com prising inclined braces extending inwardly and downwardly from the back of the door to said 10 arms, and means whereby the upper and lower ends of said braces are adjustably and movably engaged with the back of the door and said arms, to accommodate the adjustment of the latter to ward and away from each other. 5. In a garage door, a single rigid door section 16 normally disposed in substantially vertical posi tion in the doorway of the building, an arm rigid with the inside surface or back of the door, and a pivot for said arm on the structure of the 20 building, said pivot comprising a polygonal hub ing lugs, with a‘ projection on the periphery of said third disk operating between the lugs on said bracket plate, and a stud inserted through the arm and hub and fastened to said bracket plate, so that said arm and hub and ?rst-men tioned disk oscillate in unison about the axis of said stud, and said curved slots permitting slip page between disks, thereby providing lost mo tion retarding friction for the end portion of both the opening or closing motion of the door. 10 6. A structure as speci?ed in claim 5, the lugs on said bracket plate being spaced substantially ninety degrees apart, on the line of a circle struck from said axis. 7. A structure as speci?ed in claim 5, said third 15 disk having another projection diametrically op posite its ?rst-mentioned projection, so that this disk can be used as either a right or a left, with bracket plates which are exactly the same in form, but differently positioned on the build 20 on said arm, a metal disk provided with a cen ing structure. tral opening formed to receive said hub, and with curved diametrically opposite slots, a disk of friction material engaging said ?rst-mentioned disk, a third disk having bolts extending through the friction disk and the slots of the ?rst disk, a stationary bracket plate secured to the building 8.
