ROYAL 1v. RIBLET; or sPoKn vE, wnsnmeron swrvELnn iannenn Application filed June 26,

My present invention relates to improvements in swiveled hangers which while designed for various uses, as for. instance in supporting sliding doors on roller-carriages when used in garages, warehouses and other bucket type.

buildings; for use with-other types of overhead carriers or carriages; are here shown in connection with the carrier frames or trolley frames of overhead conveyers of the dump The primary object provision of means for hanging or suspending the load from a carriage in such manner that the load will'automatically adjust itself to changing relations between the carriage and the load for facilitating the travel of the In the exemplification of the in-,

carriage. ventionherein disclosed two tandem trolleys or wheel-carriers are showntraveling over a supporting cable and drawn by a traction cable. A conveyer bucket is suspended from the two carriers by a hanger, and means are provided whereby the hanger is capable of two swivel movements with relation to the carriers, one in a horizontal plane and the other in a vertical plane, for the purpose of facilitating the travel of the carriers around curves and up and down grades without disturbing the equilibrium of the bucket.

The invention consists in certain novel combinations and arrangements of parts as will hereinafter be more fully set forth. In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention wherein the parts are combined and arranged according to one mode I have thus far devised for the practical application of the principles of my invention.

Figure 1 is a View in side elevation showing a pair of tandem carriages and the dump bucket of an overhead conveyer, the hanger for the bucket being suspended from the carriages with the swiveled equipment of my invention. Figure 2 is an edge view of Figure 1 as seen from the right in Figure 1. Figure 3 is a view similar to Figure 1 showing the conveyer traveling upgrade on a supporting cable. Figure 4 is an enlarged side view of one of the carriages, with a of the invention is the r 1929; Serial no, 373,782.

hanger suspended therefrom. Figure his a top'plan ofthe central portion of one of the I carriages. Figure'6 is an enlarged vertical sectional view-at line GFQ-OI Figure 4. Figures and 8 are detail views of members of the swivel devicelfor a carriage.

. In the assembly views of Figures 1, 2 3, a dump bucket or conveyerl is'shown as 'pivotedat 2 at 'the lower ends ofapairof parallel hangers 3 and 4 which form part of the rigid frame from which the bucket is pivctally suspended. The hanger-frameis ccupled to traction cable 5 by means of a grip 6, and the entire'conveyer apparatus is suspended to travel ona supportingrail 7,

inFigures 1 and 2, or a cable as inFigure 3. Preferably eachof thehanger bars '3 and 4 is suspended from, a carriage, as 8 and'9, and these'carriages have their pairs of rollers 10 arranged in tandem formation to travelover the supporting cable or trackway. The two carriages provide for a flexibility that enables the device as a wholeto readily-adapt itself to rounding curves, and traveling up and down grade, and as the carriages are of similar construction, a description of one will suflice for both.

o In. addition to its wheels, each carriage includes a frame having parallel, top, side bars 11 and 12, at the ends 13 of which the wheels are ournaled at 14, the wheels or rollers be.- inglocated between the adjoining side bars and of course adapted to roll along the supporting cable.

At the longitudinal center of the carriage frame, between the rollers, is a transversely extending bar 15 that rigidly oins the tops of the side bars of the frame, and below the'axes of the wheels, the carriage is fashioned with n a second. cross bar, or transverse swivel head 16. The side bars of the frame are shown as open plates of truss shape and thetwo central 7 cross members 15 and 16 are integral with the side bars, but it will be understood that the carriage frame may be made up in other suitable manner if desired, and to suit different conditions. The swivel head 16 is located below the plane of the axes of the rollers, and this horizontally disposed head hasva swivel "OF-Fl I 5;

hole or socket 17 therein in line with the longitudinal axis of the carriage.

A swivel bushing 18 is supported centrally of the carriage and fashioned with a bottom r, boss 19 seated to turn in the hole 17 of the swivel head, and between the lower flat face 20 of the bushing and the head 16 a wear ring or washer 21 is placed as an anti-friction element.

The upper end of each hanger bar 3 and is fashioned as a journal 22, a bend or angle 23 being provided between the vertical bar and its horizontal journal, and it will be apparent that the journal is designed to lit and turn within the bore of the bushing.

The end of the journal is fashioned with a transversely extending hole for the reception of a cotter pin 24, and it will be evident from an inspection of Figure 6 that the journal ex- 20 tends through one of the open plates forming a side bar of the carriage frame, and also through the bore of the bushing, a cotter pin being employed to retain the journal Within the bushing. I

25 The bushing is thus swiveled to turn or oscillate on the vertical axis of the boss 19 of the bushing, and for the purpose of guiding and retaining the bushing in proper position I utilize a set bolt 25 threaded into an opening in the top cross bar 15 and alined with the vertical axis of the swivel boss. The lower end 26 of the bolt is smooth and it fits into a socket 27 in the upper part of the bushing, thus providing the bushing with both an upper and a lower axial bearing for its support and guidance. The swivel movement on the vertical axis is illustrated by dotted lines in Figure 5, and it will also be obvious that the carriages may pivot on the journals 22, thus permitting the carriages to ascend or descend a grade without disturbing the equilibrium of the suspended load. The swivel movement on the vertical axes insures flexibility of the carriages and permits them to round curves with comparatively slight friction, and without disturbing the load carried.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is The combination in a carriage frame with an upper cross bar, and a lower cross-head having a swivel socket therein, of a horizontally disposed bushing having a boss in the swivel socket, a bolt supported in the cross bar axially alined with the boss and loosely engaging the bushing, a hanger-bar, and a horizontal journal on the hanger bar supported in the bushing.

In testimony whereof I afiix my signature.

ROYAL N. RIBLET.
