To all whom it may concern:

Be it known that I, FRANCIS K. Fassnrr, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented a new and useful Improvement in Door Hangers, oi which the following is a specification.

My invention relates to door hangers of the type wherein rubbing contacts are, as far as possible, replaced by rolling contacts, and one of the objects of the invention is to confine the rubbing contacts to points where very little pressure is sustained. Another object is to provide that such metallic parts as have rubbing contact with non-metallic parts shall also have rolling contact with metallic parts, whereby they will receive a planishing efi'ect in the normal operation of the hanger. Another object is to provide simple and effective means for attaching the door to the hanger after the latter is in place, by whichthe door can also be raised or lowered, and plumbed. Another object is to construct the hanger in such manner that the door may hang plumb without putting unequal strains on the hanger parts, even though the parts are not perfect. or are imperfectly installed. Another object is to construct a hanger in such a manner that drawn steel can be used to a great extent,

and castings nearly, if not wholly, eliminated. v

rangement for connecting thehanger to a door, and

Figure 6 is an isometric view of a washer forming a part of the structure shown in Figure 5. p

Referring now to Figures 1, 2 and 3, a sin gle track 50 is secured to the wall by any well known means, and grooved wheels 51, having axles 52, carry a rider composed of parallel strips 53-53, one strip resting on the axles at each side of the wheels. The

strips are united by screws 54: passing through spreaders 55, anclalso by the upper ends of the pendents 56 which, being formed into U shape are riveted to the strips. The lower ends of the pendents are bent inward- 1y to form feet and are provided with open slots 57 to receive the bodies of bolts 58. A hole 59 is formed in each pendent of such size as to allow the head of the bolt to pass through, these holes uniting with the slots 57, thereby enabling the door to be attached alter the hanger is in place and the bolts screwed into or otherwise attached to the door. The holes extend a short distance on the horizontal part of the pendents, as will be seen in Figure 5. A clip 60 having upturned flanges 62, and a slot which reaches from one flange to the other is strung on each bolt above the jamb nut 63, and after the bolts are in place in the slots 57 the clips are pushed up into place, the flanges 62 serving to close the ends of slots 57. After the nuts 63 are screwed up against the clips, or even near them, it is impossible for the bolts to slip out of the pendent slots. The threads of the bolts may be slightly Inutilated after the nuts are screwed up, to prevent the nuts working far enough down to let the bolts out.

The wheels 51 are connected together by links 65, preferably made of wood and boiled in paraifine to furnish lubrication and at the same time render the wood insensible to atmospheric conditions. Recesses 67 (see Figure 4C) are formed in the upper edges of the links by boring holes so close to the upper edge that the edge is out out, forming narrow slots. lVhen these links are hung on the axles of the wheelsa narrow portion of the top of the axle is left exposed, thus affording an opportunity for the rider bars 53 to rest on the axles. As the slots in the upper edges of the links are narrower than the diameter of the axles, the axles are enabled to support the links. This is very clearly shown in Figure 1. In Figure 3 it will be seen that the links and the rider bars are in contact with the same zones of the axles. In other words, the bars 53 are in the same vertical plane as the links 65. The links are connected together by sprcaders 66 and screws which pass through the links and into the Spreaders, thus preventing them from slipping off of the ends or" the axles.

In addition to economizing space, which the axles and the edges of the rider bars on similar to the rolling action which. takes place between the treads of the wheels and the track 50. This rolling action has the effect of planishing the axles, giving them a hard, glossy, rust-free surface, which rotates inthe recesses 67 in the links with a very slight amount of friction. lVhen it is recalledthat the links are made of wood and are therefore very light, and it is realized that the only friction between the axles and the woodis that which is due to the weight of the links. it will. be realized how nearly frictionless this hanger is.

For the purpose of avoiding rubbing at points where metal contacts with metal, the parts are specially formed. The treads ol: the wheels are crowned and the flanges flare outward. As the tread of the track ill 1: flat, it follows thatthe points of contact be. tween the flanges of the wheels and the cor-- ners, of the track are just the same di no? from the axis of the wheel as the portin of the wheel tread which contacts with the track. Therefore the contact between the flanges and the track is a rollin ii a rubbing contact. The same pris applied at the hubs, through n'iakiin'; the hubs of the wheels slightly conical. The only part of thehnbs that contacts with the rider bars is the part which is of the same diameter as the axle, and thus rubbing contact is avoided at this point. While it might be thought that the limitations imposed by considerations ofeconomy in the commercial application of the principle just described would prevent its success in practice, this has been found, through actnal experience, not to be the case. Experience has shown that hangers constructed as above described operate with extraordinary case and. entire absence of squcaking or other noise. These hangers never require lubrication, which is a very desirable quality, for

axles to roll quite to the ends of the riders.

It will benoticed in Figure 1 that the wheel at theleft of the figure would impinge on the spreader 55 at about the time the axle of theright hand wheel. reached the end of the rider. The wheelatthe right hand of the figure would then extend about half its diameter past the edge of the door, but since that would occur when the door was at the left hand extremity of its run, there would be no objection to this. The point of all this is that the distance between the wheels may be greater that is, the wheel base'ofthis hanger is longer, in proportion to the space required for the hanger to run in,

than that of any hanger of its type heretofore made. This is an important feature in view of the prevailing use of two-part doors. As the panels of atwo-part door are usually very narrow, it is important to have the wheel base of the hanger as long as possible, and since the spacefor the hanger is frequently no longer than the space allotted to the door, hangers of the type here shown have been ill suited to such doors.

lVhile I have shown and described the preferred embodimentof this type of hanger, it is not to be understood that my invention is limited to the structure shown, as various nieiilitications are possible without departure from the spirit of the invention or exceeding the scope of the appended claims.
