ATENT OFFICE 7 Claims.

My invention relates more particularly to hangers for the conventional baggage car doors or doors of mail and combination club doors and particularly of the sliding type; the invention having for its object the provision ofa construction whereby minute adjustments maybe made and such adjustments be practically permanentline 4-4 `of VFigure l.

ly maintained, while the maintenance costdue to proper register with the door openingwill be materially reduced.

The invention has for its object the provision ci av hanger of comparatively simple construction A which may be easily applied and readily adjusted tof-bring the door into complete register with the Ydoor-opening and thus provide a substantially weather-prooi closure without resort to improper pressure and hence undue strains. I The objects and advantages of my invention will all be readily comprehended from'the detailed `description of the accompanying drawing wherein:

Figure l illustrates a pair of my improved hangers, in front elevation, shown applied to a door and top rail of which merely portions 'are shown.

Figure 2 is a side view of my improved hanger.

Figure 3 is a vertical sectional view taken substantially on the line 3-3 of Figure 1.

Figure 4 is a cross sectional view taken on the The specific embodiment of the invention as disclosed in the drawing comprises a roller carrying and rail lapping member or casting Il] of proper width and length to extend from the top or supporting rail II, which is suitably secured to the car wall or side immediately above the door openingarid toward one side thereof in the usual manner; the cross-sectional configuration `of the rail being shown in Figure v3. One leg or side of the channel rail I I constitutes a trackway for th roller I2 which is journaled on the pintle or pin I3 which is removably secured in place.`

' "The upper end of the casting or member I0 is of width greater than the diameter of the roller I2 and is of chambered rectangular cross-section as shown at Ill in Figure 4; the upper end of the casting Ill constituting a housing for the iianged roller I2, open at top and bottom.

The rear wall of the housing I4 is apertured to receive the non-threaded Yend oi the pintle or `pin I3; while the front wall is made of increased thickness or provided with'a boss and this boss portion provided with a tapped opening to receive'the enlarged threaded end I5 of the pintle 13; e end i6 of the pintle I3 beyond the threaded portion I5 is shown rectangular in cross-section so as to lit into a correspondingly shaped slot or opening in a pintle holding plate or locking member I1. Y

The ends of the plate or locking member I1 are each provided with a tapped hole adapted to be brought into register with tapped holes arranged in the-front wall of the casting or member il! on opposite sides Vof the pintle receiving hole. After the pintle i3 is inserted through the hole `in the front wall and through the hub or hole in the roller, plate or locking member I1 may be applied to the rectangular or non-circular end` I6 of the f pintle and the plate used in lirmly screwing the threaded portion of the pintle i3 into the tapped boss portion of the front wall of the casting ID and after the pintle is entirely screwed into place with its inner end in the hole in the rear wall, the pintle with locking plate Il is turned to a Apoint where the tapped holes in the plate il will register with the tapped holes in the front wall of the casting l0; the plate being then secured in this'adf justed position by inserting screws I8, I8 through the plate Il.

With plate or locking member I'I secured in proper place by screws I8, I8, it is apparent that rotative or unscrewing movement of the pintle, due to the rolling action of roller I2 will be impossible, although a'dismantling of the'rrroller carryingfelement may be readily accomplished if occasion should require.

The forward o-r outer face of the casting ID, intermediate of the top and the bottom, is formed with an outwardly disposed boss I9 provided with a tapped opening to receive the threaded end of the bolt 26 which passes through the eye of the eye-'bolt or adjusting screw 2|. Y

The lower end of the casting l0, at a slight distance beneath the boss I9, is provided with a vertically disposed slot 22 `ofpredetermined length and arranged in alignment with the boss lll, as shown in Figure 1.)

' To the rear "of the skirt or slotted lower portion of casting I is a door engaging plate or anchor member 23, which is adapted to be secured to the door 24 in any suitable manner as by screws 25 see Figure 3. The forward face of the anchor member 23 is provided with a vertically elongated boss 26 which is adapted to slidably t into the slot 22 in the casting or roller carrying member I0; and this boss 26 in turn is provided with an outwardly extending lug 21.

The lug 21 is intended to extend outwardly a distance sufficient to bring the vertical opening through the lug into vertical alignment with the pivot screw Z and therefore into position to receive the depending eye-bolt or screw 2|, see Figure 3.

The threaded portion of eye-bolt 2! is provided with adjusting nuts 28, 28; one of the nuts being threaded onto the bolt before the latter is inserted through the hole in the lug 2'! of the anchor member or plate 23, while the lower nut 28 is then screwed onto the bolt 2i and this nut preferably locked in its adjusted position in any suitable manner as by means of a lock-nut 29.

As shown in Figures 1 and 3, the vertically elongated boss portion 26 of the door anchor member 23 is of length considerably less than the length of the slot 22 in the roller carrying plate or casting I0, thus permitting relative adjusting movement between door anchor 23 and the roller carrying plate l0.

Where the door hanger is used for the large sliding doors of a baggage car, it is usual to employ at least a pair of hangers, as shown in Figure l, adjacent opposite ends of the door; and if desired the rear lower part oi" the casting i@ may be provided with a pair of vertically disposed serrated ribs or flanges, as at 3U, arranged on opposite sides of the door anchor receiving slot 22 in the casting i6; the serrations being adapted to effect slight frictional relation with the face of the door 24 and thus somewhat assist the door anchor 23 in holding the door.

The application of my improved hanger and the mounting of the door on an overhead rail may be readily accomplished by assembling the roller as heretofore described and locking the pintle I3 against accidental movement induced by the repeated back and forth rolling of the rollers along rail Il; then apply the roller carrying element to the overhead rail Il. The anchor members or plates 23 are then vertically secured to the door so as to register with the slot 22 in each roller carrying member or casting I0 and the lug 21 disposed through the slot 22.

The eye-bolt 2 i, with the upper nut 28 screwed thereon, is then inserted through the hole in the lug 21 and bolt 29 passed through the eye of the bolt and screwed into the tapped hole in the enlarged or boss portion I9 of the roller carrying plate or casting lll. With the bolt 2D in place, the lower nut 28 is then screwed onto the end of the door suspending bolt or member 2l until it engages the lower face of the lug 27. After the lower nut 28 has been screwed lengthwise of the door suspending bolt 2| until the door has been raised from the floor and at the same time will freely t the door opening, lock-nut 2S is then applied to the bolt 2| and the upper nut 28 screwed downwardly into firm contact with the top of the lug 21. v

Member I0 is shown provided with vertically elongated slots 3l, on opposite sides of slots 22, adapted to loosely receive bolts with washers as at 32; the bolts being secured to the door. This permits vertical adjustment between door and member IG to be made while assisting the boss 26 against lateral movement.

With the elongated boss 26 of anchor member 23 slidably fitting into the slot 22 in the roller or bearing carrying member, it is evident that lateral or sidewise movement between the door and the hanger member Il! will be impossible and a positive relation between the door and roller carrying member I maintained.

As is apparent from the construction illustrated, the door is entirely suspended from the bolt 2| and practically micrometer or very fine adjustments can be made. With the conventional door hangers adjustments of a coarser nature, as for example about one-eighth of an inch, are merely possible; whereas with my improved construction adjustments of one-thousandth of an inch are possible and these adjustments made practically permanent, which is not the case with the conventional hangers due to slippage of the ratchets, permitting the door to get out of adjustment and at times making it impossible to operate.

The eye portion of the door suspending bolt 2l is preferably provided with iiat faces so the bolt may be free to swing on the bolt 20; and instead of the plain roller i2 it is apparent that a rollerbearing type may be employed; and while I believe the construction shown to be the best embodiment of my invention certain modiiications may be made without departing from the spirit of my invention which has been described in terms employed merely as terms of description.
