SPECIFICATION forming part of Letters Patent No. 569,965, dated October 20, 1896. Application filed January 20, 1896` Serial No. 576,098. (No model.)

To LZ/f whom t may concer/L:

` Be it known that I, HENRY L. FERRIS, of IIarvard, in the county of McHenry and State of Illinois, have invented certain new and useful Improvements in Door-Hangers and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, 1o which form a part of this specification.

This invention relates to improvements in door-hangers, and more particularly to that class of door-hangers comprising a revoluble wheel mounted in a strap or frame, the latter to be secured to a door, the frame having an overturned portion or housing adapted to protect the wheel from the weather, and in which the wheel is supported upon a track or rail suitably secured to the building.' zo The improvements more particularly relate toa method of securing the wheel and its frame to the door and prevent a buckling of the frame, and also means for securing the wheel within the housing and lto the frame 2 5 in a manner that will greatly reduce friction, obviate the necessity `of oiling, and secure an easy movement without the liability of creaking.

Devices of the character referred to must 3o be strong and durable to withstand the severe usages to which they are put, usually upon barn, stable, or other heavy sliding doors, and mustalso be of cheap construction. It is found in practice that inasmuch as the frame 3 5 which connects the door with the bearingwheel is one side of the line of draft, which passes through the bearing-wheel, and the supporting-track, over which the wheel runs, the said frame has a tendency to and does, in 4o fact, bend and buckleat a point slightly above the door, which, in addition to other inconveniences, causes the door to swing away from the building and not close properly. This difficulty I overcome by so constructing the frame as to embody with it a Vstrap arranged in the form of a truss, one end of which truss is secured to the frame and the door and the other end of which is secured to the upper portion of the frame at a point 5o above the door and opposite the roller or wheel-bearing, while the central portion of said strap or truss is properly supported at or near the upper margin of the door. I nd this expedient not only corrects the fault above/indicated heretofore existing in barn- 5 5 door hangers, but possesses other advantages. Heretofore it has been customary to mount the bearing-wheel upon a short shaft or spindle and to provide suitable bearings in the frame or housing within which the ends of 6o said shaft may rotate, and it has also been the practice in some of the cheaper forms of hangers to mount the shaft or spindle nonrotatively in the housing or frame and to permit the wheel to revolve over it. In both of these constructions considerable friction is developed, and, moreover, the parts speedily wear out, unless a specially-prepared shaft or spindle is provided having accurately-fitting journal-bearings. Such latter construc- 7o tion is, however, undesirable because of the expense. To lessen the friction at this point I have provided apertures in the housing, and have partially filled each of said apertures with a flanged thimble. The hub of the wheel 7 5 is provided with a relatively large opening. A common bolt is then passed through the iianged thimbles and through the opening in the hub of the wheel, and by placing a nut on the bolt the parts will be firmly secured 8o together. In this construction the hub of the wheel has no interior bearing upon the bolt, which does not have the function of an axle or spindle, but solely that of atie-bolt. The outer ends of the wheel-hubs are slightly reduced in diameter, first, to form the shoulders against which the frame or housing may be drawn by the said tie-bolt, and, secondly, to form journals which rest within suitable bearings within the said flanged thimbles. 9o As a special improvement I enlarge the aperture or journals in the flanged thimbles, so as to afford a space between the journals and the ends of the hubs that shall constitute a j runway or race for antifriction-balls, which when used reduce the friction to a minimum. The invention will be more fully understood by reference to the accompanying drawings, in connection with the description and the subjoined claims.

In the drawings, Figure 1 represents in a side view a portion of a door with my irn- TOO proved hanger attached in position upon a rail. Fig. 2 is central vertical section of the same;l taken on the line 2 2 of Fig. l, and looking in the direction indicated by the arrows. Fig. 3 is a view similar to that of Fig. l, illustrating a inodied form of the frame. Fig. 4 isa vertical sectional view taken on the line 4 -t of Fig. 3 and looking in the direction indicated by the arrows.

In said drawings, A represents the side of any suitable building, to which a track A is secured by means of any suitable bracketsupport a.

A2 indicates a door. rlhe frame consists of a plate B of suitable length and width bent upon itself at b, so as to form at its upper end a suitable housing B with two sides H192, between which the wheel C is mounted. The plate B may he secured at convenient points tothe door A2 by means of bolts b3 or otherwise.

I) is tie-bolt, rivet, or the like adapted to secure the wheel Cin position in the housiuo; sud B2 is s strap suitably tout iu its middle portion und seoiired tothe plete B at its lower end bye rivet b or otherwise oud, seoured at its upper eud by tho soule bolt or rivet l) that secures the other parts together. A thimble or spreader-block B3 rests upon the plo-te B sod the .strap B?, sud d bolt oi? rivet posses tht-oust suitobleeooituies in the plete, sui'eederfblook. und the strep oud secures the saine together in an obvious uiouuet lt will thus be eotioed that the stiap T2 with the spreader-.bloeit B3 forms a truss. with the plate l? and by greatly stloustlieuiue und stiiioiiius the letter rieveuts all tendency to bending and buckling at any point above the upper margin of the door.

E is suitable tliiuible or bottling of suoli diameter us to properly tit within apertures through the sides t/ t? of the housing oud fue prevented fioiu pussies ventirely through said apertures by reason of the flanges c thereon. Each thinible-bearin g E has a central aperture e', adapted to receive the bolt or rivet D. The bearing-wheel C is of the usual construction, having a groove orface c, adapted to engage the upper edge ofthe track-rail A and provided with suitable hubs c. Openings c2 are made through the hubs c andare of greater diameter than the diameter of the bolt or rivet D, as clearly illustrated. The ends oi' the hubs o' are turned down or reduced in diameter for the purpose of forming journals c3, on which to support said wheels within said thimblebearings E. The inner side of each thilnblebearing E is provided with an annular recess or opening egof a size adapted to accommodate the said journals c3. In the forni shown in Fig. 2 these apertures or journal-bearings t? uro oousideiablyloisei 1,11A Vdiameter than that of the journals or turnedfdown portions c3 of the hub, whereby a ball-race is aiiorded, Witliiu Whioli. eutifiiotiouftolls F may be placed. If the balls are not used, the

hub-

journals c3 rest directly within the apertures or journal-bearings e2 in the thimbles E, as shown in Fig. 4, but I prefer to use the antifriction ball-bearings illustrated in Fig. 2 as a construction in which the friction is rcduced to a minimum.

Instead of the housing B and the plate B being of one piece, as shown in Fig. l, itis sometimes preferable to make the housing B', as shown in Figs. 3 and 4, of a separate piece. In this form of construction a U-shaped frame-plate B4 is suitably bolted to the door, with its ends, which project above the door, rigidly secured to the housing by rivets b". In this form of frame it is preferable to provide the spreader-block B3 with an annular flange 197 and to extend the bolt or rivet bs, that secured the strap B? to the door at its center, not only through the spreader-block, but also through tlieuoret Doitiou of the door. This modified forni oi? construction constitutes a very strong and substantial frame and will usually be used where the width ofthe plate B would otherwise exceed three or four" inches.

0f coulSe it is immaterial, so far as the truss is concerned, whether the ball-bearings are used ofr Whethoi the wheel has journal-hubs which rest directly within the thimbles. It is equally unimportant to which form of frame the truss shall be applied, and l have therefore illustrated bothfforins in the drawings.

' rlhe invention is neat, simple, and durable aud lios 11o oomplioated puits to eet out of order, is easily assembled Without the oid of skilled labor; "and relatively olioup iu. ooustruction.
