DOOR-HANGER Specification of Letters Patent.

Patented Aug. 20, 1907.

Applicant mea December 21, 190e. serial No. 348,900.

To all 4allor/t it may concern:

Bc it known that I, CHAnLEs DIPPLE, Jr., a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of \'e\\' York,- with postv ollice address 7 St. Francis Iluce, have invented certain new and useful Improvements in Door-Hangers, of which the following is a specilication.

My invention relates to lhe construction of autifriction bearings for sliding doors, windows or other objects.

The invention is especially useful for doors, and for the purposes of illustration I will, therefore, describe the same as applied to a door.

lhe main object of the invention is to. provide a simple and effective device having the necessary strengthand also so constructed as to occupy but little space. I

Briefly' stated, my invention consists in the combination with a hollow track or rail consisting of metal tubing having a longitudinal lslot to permit connection with the door or other object, of a carriage consisting of a bar having two race ways upon its two opposite lvertical faces and anti-friction devices such as balls `suitably lretained upon said race ways and traveling also upon race ways formed on the inner face or wall of Said hollow track or rail.

In carrying out my invention, I prefer to employ a metal tube which, in cross section, would be angular in forni and would have the slot so located that the balls or anti-friction devices will each, in addition to its bearing upon the side of the bar, have a double bearing upon the interior of the rail or track.

My invention consists further in an improved iorni of hollow track which is triangular in cross section and which has the slot formed in one oi its sides.

My invention consists further in other details of construction and combination of parts more particularly hereinafter described and thon specified in the claims.

In the accompanying drawings, Figure l represents my improved apparatus in side elevation as applied to a sliding door. Figs. 2, 3 and 4 are full sized cross scctions through various forms of hollow track or rail.

Fig. 5 is a side elevation to reduced scale of the sliding bar or carriage. Fig. 6' is a cross section of the same. Fig. 'Lis a perspective view of the ball retainer.

l indicates the hollow track or rail suitably supported inlthe desired position by hangers or equivalent devices of any desired number as indicated at 2.

3 is the sliding door and 4 is the bar or carriage to which the door is suitably attached. In the opposite faces of the bar or carriage 4 are formed suitable race ways* or grooves 5 which receive the anti-friction devices consisting, as usual in the art, of the balls 6.

The manner of attaching the door 3 or other object to the bar orcarriage 4 may obviously'be varied indefinitely, some of the orms oi attachment being clearly shown so as not to require further description in Figs. 2, 3 and 4.

The hollow track or rail l has a continuous longitudinal slot formed in its side next the door to permit the passage ofthe bar or carriage or of the attachment by and the door, window sash or other object. The hollow track or rail 1 may be of various forms in cross seej tion; being practically tubular.

The track or rail in Fig. 2 forms a true tube, being practically circular in cross section and each ball 6 while having a bearing in the race way or track 5 has but one bearing against the inner wall of the hollow track.

In the forni shown in Fig. 3, the hollow track or rail forms an angular figure in cross section and the longitudinal slot therein is formed between two ofthe meeting sides. Each of the two sets of balls o n the opposite sides of the bar is then permitted to have two bearings on the inner face oi the hollow track as shown. Obviously the hollow track or rail might be polygonal instead of rectangular in cross section, and the two bearings for each ball upon the inside of the rail instead of being upon meeting sides might be upon sides separatedfrom one another by an intermediate side or face of the gure.

In Fig. 4 I show a preferred form of hollow rail which is, briefly stated, triangular Iin cross section and has its longitudinal slot formed in one side. This gives each anti-friction ball a double bearing on the inside of the hollow track, one bearing being on the side in which the slot is formed and the other on the adjacent inclined side.

Attached to the top of the bar or rail 4 is a suitable devices. This retainer may consist, as shown in Fig. 7, of a channel-shaped piece of metal 7 placed in inverted position on top of the bar or carriage 4 so that its sides will drop below the same and to positionto cngage the balls 6 which run in notches or openings at Y in the ball retainer. The top of the channel-shaped retainer is provided with a slot through which passes the retainer screw 8 which prevents the retainer from entirely leaving the bar and from moving in any direction other than that taken by the bar. Obviously a large number of balls might be used oneach side of the bar, in which case the number of notches 7 would be correspondingly increased.

Near each end of the bar 4 and on the top thereof, I provide a suitable adjustable stop comprising, preferably, a screw 9 by settingwhieh an adjustment is provided for any inequalities of thickness in the rail or track thereby affording means lor preventing the bar from jumping or kicking out ot' its right position as it means of which connection is formed between said bar retainer for the anti-friction balls or other anti-friction' or l`orth in the slotted rail or track. Il' for instance the hm' he of less thickness, it would he Dermittedto settle down further in the hollow truck since it is sustained by the luterul engagement ol the brill with its sides and with the walls oi' said tra-ok. ln such ense the bur would he Cuprthle ol' u greater up und is moved had;

clown play in thehollow trael; und to mko up such play the screw is adjusted to projet-t to u greater (list-nce from the top of the hui' so :is to niovtl very closely to 'the top ol the hollov.v ruil and thereby prevent the Suid btu' from nio'ving in anything but :L straight line.
