DOOR-HANGER.
Specification of Letters Patent.
Patented Mar. 2, 1915.
Application filed July 25, 1914. Serial No. 853,011.
To all whom it may concern Be it known that I, HUBERT F. FRANKLIN, a citizen of the United States, residing in the borough of Brooklyn of the city of New York, in the State of New York, have invented certain new and useful Improvements in Door-Hangers, of which the following is a specification, reference being had to the accompanying drawings, forming a part hereof.
This invention relates to devices for moving positively the separators used for spacing the usual ball or roller supports in traveling doors.
It has been the usual practice, where rolling elements are employed for the support of traveling doors, to hold the rolling ele ments in spaced relationship by means of separators or spacers which are formed to receive the rolling elements and which are themselves impelled by the rolling elements during movement of the door. It has been found that where the balls, for instance, are relied upon to move the separator, the play of the balls in the tracks brings about a creeping of the balls with the separators, with respect to the tracks, so that eventually the supporting elements are moved out of their most effective positions. Then, too, when the balls and the separators thus creep along the track the carrier is apt to become jammed or, at least, the balls do not roll freely with the traveling carrier, but move spasmodically and offer varying degrees of friction to the movement of the door, thus impairing its free anti-friction movement from open to closed position, or vice versa.
In accordance with the present invention the difiiculties recited are met by providing a pinion which is connected to the separator and is in operative engagement with preferably two racks, one of which is mounted on the corresponding carrier and the other of which is mounted in juxtaposition to a fixed part or other stationary object. The use of two such racks, arranged in the manner stated or in some equivalent manner, will probably be the preferred construction in order that the separator may be assured an invariable positive movement at one half the speed of the movement of the traveling carrier on which, of course, is suspended the door.
. In the illustrated embodiment of the in- 5 vention a single traveling door mounted on a carrier which is disposed between two fixed tracks and is mounted on rolling balls, is shown.
Reference is now to be had to the accompanying drawings for a detailed description of the invention.
In these drawingsFigure l is a fragmentary view in front elevation of a single traveling door equipped with the improved devices. Fig. 2 is a view in end elevation of so much of the structure as is shown in Fig. 1. Fig. 3 is'a sectional view taken on the plane indicated by the line 33 of Fig. 1 and looking in the direction of the arrows.
In the construction illustrated, there are two fixed tracks a, 1;, having their proximate edges grooved longitudinally as at a, a, to receive balls 6, between which is supported a moving carrier 0 on the upper and lower edges of which are also formed longitudinal grooves c, 0', to receive the balls. From the carrier 0 is suspended a door (Z of any desired form, as by hangers 0 The balls 6 are held in spaced relationship by a separator e which may be of any approved form.
To the fixed track 0, is secured along the outer face thereof, a rack 7", while along the outer face of the carrier 0 is secured a rack 9, these two racks being engaged operatively by a pinion e and being of such length as to permit the required full movement of the door d while maintaining the engagement of the pinion with each of the racks at all times. The pinion e is secured to the separator e as through a threaded stud 6 engaging an upwardly extending flange e which may be formed integral with the separator 6. It will noW be understood that movement of the carrier 0 through pressure applied to the door d imparts bodily movement to the pinion 6 through its engagement with the racks g and 7", and that such bodily movement of the pinion 0 results in a corresponding movement of the separator e and the balls I) with which the separator engages. The speed of the bodily movement referred to is, by the arrangement employed, necessarily one half of the speed of the door so that the separator e and the balls I) are maintained at all times in such relationship to the carrier 0 as to present a most effective support therefor. Moreover, positive movement of the separator e and of the balls 72 eliminates that free movement of the balls in the grooves a, a, and 0', c, which ordinarily occurs and which results in creeping of the balls With the separator along the tracks or jamming of the balls.
As pointed out hereinbefore, the invention is not to be limited in its application to a'single traveling door, but may be employed equally well with two or more doors traveling at differential speeds, and where the devices are employed under such circumstances, the actuating pinions for the differential doors may serve in a dual capacity and be arranged to drive positively the separators, in the manner pointed out in this specification. Changes of this character and all other changes which fall within the range of mechanical skill may be made without departing from the spirit of the invention, provided such changes fall Within the scope of the appended claims.
I claim as my invention:
1. In combination with a traveling door, a carrier therefor, a fixed track, anti-friction rolling devices interposed between the track and the carrier, a separator for said anti-friction devices, and means to move the separator positively at a predetermined speed during movement of the door.
2. In combination with a traveling door, a carrier therefor, anti-frictionudevices on whichthe carrier is slidably mounted, a separator for the anti-friction devices, gearing connected to the separator and a rack mounted on the carrier and in engagement with the gearing, whereby the separator is moved positively during movement of the carrier.
3. In combination with a traveling door, a carrier therefor, balls on which the carrier is slidably supported, a separator for the 7 balls, a gear mounted movably with thejseparator, a rack carried by the carrier and a second fixed rack, the gear meshing with both of said racks at'all' times, whereby the separator is moved positively during move- 7 ment-of the carrier and at a speed equal to one half of the speed of the carrier. V
4. In combination with a traveling door, a carrier therefor, fixed tracks between which the carrier is 's lidably mounted, balls interposed between the carrier and each of the tracks, a separator for the balls, a gear mounted on the separator, a rack 'fiXed to one of said tracks, and a secondrack secured to the carrier, the gear being in mesh with the teeth of both of said racks at all times, whereby movement of the carrier brings about positive movement of the separatorat a speed equal to one half of the speed of the carrier. 7
