To all whom t may concern.'

Be it known that I, RAFFORD PITT, a citilzen of the United States, and a resident of This invention relates to improvements in door hangers.

By the use' of my invention I am enabled to produce a door hanger preferably of the ball-bearing type which will not only be very light in weight, noiseless and inexpensive to manufacture, but will be free from dust and dirt, consequently permitting the movement of a door to which it is attached with great facility, and said hanger will also have great rigidity and durability.

In the preferred embodiment of my invention which comprises a stationary member and a member movable relatively thereto, the stationarymember is rolled from sheet metal to provide a t-rack portion preferably with raceways for balls or other similar antifriction devices, and has a securing portion in the form of a Harige integral and preferably co-extensive with said track portion, said integral` securing flange forming a shield against the admission of dust to the raceways in the track portion of said stationary member and providing a flat securing 'surface for said stationary member, thus enabling the same to be secured at various points over the doorway, and adding rigidt sity to the structure without undue weight.

vThe movable `member is also preferablyl rolled from sheetY metal bent to provide a track portion with raceways registering with the raceways in the stationary member to form channels to receive balls or other anti-friction devices and a securing portion `iin the form of a flange integral andl preferably co-extensive with said track portion so as to provide a ready device for securing the movable member rigidly and securely to the door and keeping out dust and dirt from the operating parts thereof, balls be tween the raceways in the movable and staf tionary members and ball-containers preferablyfcomprising two abutting and connected lstrips of sheet metal ribbed longitudinally to a'ord rigidity and provided with 'ball-containing pockets formed by cut-4 ting spaced and registering apertures in each of the abutting strips and blistering7 or bending the edges of the lower strip downwardly and blistering or bending the edges of the apertures of the upper strip upwardly, whereby a pocket is formed for the balls.

Figs. 8 and 9 are sections at right angles to each other of a ball pocket or ball seat in said container; and

Fig. 10-is a side elevation of a construction embodying a modified arrangement of the ball containers.

Referring now to Figs. 1 to 3 and 5 to 9 inclusive, l indicates the wall surrounding a doorway, 2 the stationary member of a hanger embodying my invention which is preferably of the cross-sectional form shown in Figs. 3 and 6 and comprises a track portion 2a and a combined securing portion and dust shield 2b provided along its length with suitable screw apertures to permit fastening thereof by screws 3 to the doorway. The said stationary member, as shown, is preferably co-eXtensive with the doorway and is preferably rolled up from a strip of sheet metal to provide intermediate the longitudi-V nal edges of said strip, tracks or raceways 2c, 2d and 2e respectively, terminating at one longitudinal edge in the flange 2b which eX- tends at an angle to said track portion, the other longitudinal edge being so disposed with. relation to said flanged portion that when the said stationary member is secured.,

I to the doorway an entrance or operating slot 2' will be provided to permit the reciprocation therein of the door connecting ortions of the movable member hereina ter described.

The movable member 4 of the hanger also preferably comprises a track portion 4a and flange portion 4b which 1s preferably provided With suitable screw a ertures and 1s connected along the upper e ge of the door n by screws. Said movable Vmember is, as

shown, preferably co-extensive with the.

transverse edge of the door and is also preferably rolled up from a strip of sheet metal to provide intermediate the longitudinal edges of such strip, tracks or raceways 4, 4d and 4*3 respectively which reglster with the tracks or raceways 2c, 2d and 2e of the st ationary memberand one edge of saldl strip terminates in the said securing flange 4b which is of such conformation and is so disposed with relation to the stationary member as to extend through the slot 2f and permit attachment of said track portion to'the door.

In Fig. 4 said securingflange is angular in conformation, Figs. 3, 5 and 6 lllustrating the same as extendlng upwardly from the track-portion and thence outwardly through the slot 2f and downwardly to the door where it is'secured in any sultable manner. n

In Figs. 3 and 5 said flange 1s shown as secured at one side of the door adJacent to the top edge thereof, and in Fig. 6 as abutting against and secured to the top transverse edge of the door.

In Fig. 4 I have illustrated a hanger embodying a modified form of my lnventlon in which the stationary member is rolledup from a sheet of metal 10 to provide a track portion 10a having longitudinal raceways 10c--10d and a securing flange 10b'at one longitudinaledge thereof, the opposite longitudinal edge being so disposed in rela-' tion to said flange 10b as to provide an operating slot 10f. The movable member lis also preferably rolled up from a single strlp of sheet metal to provide a track portion 14 having ball raceways 14a-14b registering with the raceways 1()c and 101 of the stationary member to form ball channels therebetween, one longitudinal edge of said strip being bent to provide a flange 14c to permit the securing of the same in any sultable manner to the door.

In all the figures of the drawings I have illustrated balls 7 interposed in the ball channels formed between the longitudinal raceways of the stationary and movable l members respectively and these balls are preferably seated in ball-containing pockets formed in ball containers 8 comprising two abutting and connected strips of sheet metal 81-8", ribbed longitudinally to afford Maaate rigidity and pierced with spaced apertures, the edges of which apertures are blistered or bent upwardl and downwardly as illustrated in Figs. 8 and 9 to provide such pockets.

Separate hall containers are preferably provided for each set of balls. rIhus in the construction shown in Figs. 3, 5 and 6, separate ball containers will be provided for the upper hold-down balls which are preferably disposed above the container for the lower or carryin balls and in the relationship shown in ig. 1, namely, the ball-'container for the carrying balls extends substantially three-quarters of the length of the stationary member and the containers for the hold-down balls extend substantially onehalf of the length of the door which it is 'desired to hang, and is disposed centrally above the carrying-ball container.

Stops are also preferably provided at suitable points to prevent a creeping of the balls and as shown in said Figs. 1, 3, 5 and 6 stops 20 are attached by screws 20L at each end of the'stationary member and such stops close or seal up the ends of the said stationary member, thus adding to the dustproof characteristics of the device. Stops 40 are also preferably provided at opposite ends of the door to limit the movement of the hold-down ball-container with relation to the carrying-ball container, so that during the continuance of such movement said container will always be' in substantially the same disposition to the carrying-ball container, though both containers will change their positions relatively to the door and stationary member, and the said stops 40 are preferably of the configuration illustrated in Fig. 6 so as to limit the movement of the hold-down ball-containers only while permitting free movement of the carryingball containers.

In- Fig. 10, I have shown a construction in which the container for the upper or hold-down balls may be equal in length to the container for the carrying balls. yIn this construction, the stops 20 at the ends of the door orl movable member may be omitted. Such an arrangement of containers is suitable for the construction shown in cross-section in Fig. 4, though it may be employed in the construction shown in cross-sectioniin Figs. 3, 5 and 6. With said last mentioned arrangement of containers, however, the upper ball container.

istl

Laagste;

permanently magnetic, and 4counsefpiently the balls lof the upper or hold-down ballcontainers will be retained against the track or tracks below which such balls abut.

In other respects, the construction shown in Fig. is similar to that'illustrated in Fig. 1.

If desired, eitherv of the constructions may be so magnetized and while such magnetizing of the track member willfhold the balls against the respective tracks so` that` it will be unnecessary to connect the cond tainers by a Web or the like, it will have no eifect upon the movement of such balls or containers in relation to the tracks.

Another feature of my invention is the provision in a hanger of the' type'speciied of a wiping element adapted to close .the space between the stationary and movable members and therefore keep out any dust from the movable parts, and also keep out cold air .and draftsfwhich are ordinarily admitted through the spaces betweenthe parts of ball bearingA door hangers.l
