Be it lznown that` LWWILLIAM W. `Duemila, a citizen of the United States, residing `at Davis, in the county of Tucker-and `.State of WestVirginia, have invented certain `new and `useful Improvements in Pivoted Swing Hangers, of whichthe following is a speciiication. y l y y v 1 invention relates broadly` to supports, and has particular reference to pivotedhangers, :For swings, hammocks, or the like. f,

An important obje-ct of the invention is to provide a pivoted hanger of the` above mentioned character, which may be main tained suitably lubricated `for a long` period, C, in` operation. I i

A further objectuoffthe invention vis to provide pivotedihanger ofthe abovefmentioned character, equipped with ball bearings, `so constructed thatthefy takeradial and end thrusts, whereby the hanger may be vertically disposed, or arranged atanangle, inuse j y i A urtherobject of the invention" is to provide a pivoted hanger ofthe above Inentioned character, which isistrong, durable, and will ,last `practically indefinitely.

Other objects and ``advantages of `the in? lvention `will be apparent during the` .course of the following descriptionj y Inthe accompanying drawings forming a part of this speciiication, and in which like numerals are employed to designate like parts throughout the same,

Figure lis a side elevation of a pivoted hanger embodying my invention,

Figure 2 is an edge elevation of the saine, Figure 3 is a side elevation of the device, parts being shown `in central vertical section` Figure i is a transverse sectional viewy taken on line 4 4: of Figure 1, parts broken away, and parts omitted, and,

Figure 5 is a. detail section taken on line 5 5 oit' Figure 3.

In the drawings, wherein for the purpose of illustration is shown a preferred emthrough which screws 12 may be passed, for

engagement with a horizontal support 13,

` suoli the ceiling otra porch. The numeral 14 `designates a screw, which has its head anchored orembeddedin the casting l0,`and this screw is adaptedl for engagement with the support 13. lt is obvious that the screw 14: mayl be used alone or with the screws 12,. The invention is not restrictedto the ein ployment of screw or screws as attaching means, as any other suitable means may be employed for this purpose, such as bolts.

The body portion or housing is pro vided upon its opposite sides with preferably cylindrical,chambers 15, formed there-- in, ior the reception of ball bearings. These ball bearings comprise race-ways `orguides 16, receiving balls 17 held therein by re` tainerslS, as shown. The race-ways 16 enat their inner ends, `an :annular Yflange V19, forming a central iieed chamber`20 for grease .or other lubricant, which is ted to the ball bearings, as will be described.L The chambersl and 20 form a recess .extending through the hanger block from one. side to `central feed chamber 20, as shown.

The numeral 23 designates a pivot suspen sion pin, provided at one end with ahead 211;, Carried by the` pin 23 is a thrust ring 25, having `at ,itsv inner end` a ball receiving groove or race-way'26, arranged obliquely. The pin 28 has a portion of its length, outwardly of thering 25, slightly reduced in diameter, and screw threaded, for receiving thereon a coacting thrust ring 27 provided at its inner face with a ball receiving groove or race-way 28, arranged obliquely. The race-ways 26 and 28, face inwardly, and are arranged opposite to each other, and engage with the balls 17, as shown. The thrust rings 25 and 27 coact with the ball bearings, constituting ball bearing devices for taking both radial and longitudinal thrusts. As the screw threaded portion ot the pin 23 is slightly reduced in diameter, the same does not contact with the raceways 15, but are spaced therefrom, and this permits the grease within the central feed chamber 20 passing' to the balls in the ball bearings, to retain them suitably lubricated. rlhe numeral `2S) designates a swinging member' or yoke, preferably embodying sidesBO, the lower ends oit which are apertured for receiving threaded shanks 31, carried by a transverse member or boss 32, having an eye 33 formed thereon. The threaded shanks 3l carry nuts 34, having screw threaded engagement therewith, and lock washers 35 are preferably arranged between these nuts and the sides 30, to lock the'same together. It is thus seen that the sides 30 are rigidly connected with the transverse member or boss 32, but may be separated therefrom, when desired. The upper ends of the sides 32 are provided with enlarged preferably circular heads 36. These hea-ds have openings 37 formed therein. |The head 36 to the left, Figure l, is arranged between the head 24 of the pin 23 and the thrust ring 25, while the head 36 to the right is arranged between the thrust ring 27 and a nut 38, having screw threaded engagement with the screw threaded portion of the'pin 23. Any suitable means may be employ-ed to prevent accidental rotation of this nut 38, such as a cotter pin 39. Means are provided to prevent the heads 36 turning upon the pin 23, and to accomplish this, these heads are provided with inwardly projecting keys or extensions 40, adapted to enter a longitudinal groove 41, formed in the pin 23. In order that the grease may not work outwardly from the bearings, I arrange washers 42 such as felt washers, between the keepers 18 of the ball bearings, and the heads 36.

In view of the foregoing description, it is obvious that I have provided a hanger, which will operate without noise, which is strong and very durable. The pivoted yoke 29 will turn about the axis of the pin 23, with the least friction, by virtue of the ball bearing devices. The arrangementvof the race-ways of the ball bearing devices, provides means whereby these devices servo to take up radial and longitudinal thrust.

This permits of the han-ger being supported vertically, as illustrated in Figure l, or the same may be arranged diagonal, as when it is employed to support a hammock. The swing or the like is suspended from the eye 23, as is obvious.

It is to be understood that the form of my invention herewith shown and described are to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the subjoined claim.

Having thus described my invention, what I claim is:

A hanger block to be secured to a support and having a recess formed therein extending from one side thereof to the other', said recess having an internal annular flange arranged centrally thereof, a grease cup attached to the central portion of the block to supply grease to the recess at its center, race ways mounted within the end portions of the recess and engaging the sides of the internal flange, balls held within the race ways, a pivot suspension element passing through the recess and race ways, radial and end thrust rings mounted upon the pivot suspension element upon the outer side of the race ways and engaging the balls, a hanger element embodying side plates arranged in close relation to said sides and apertured for receiving the pivot suspension element, packing arranged between said sides an-d the side plates, and means carried by the pivot suspension element for holding the side plates in proper contact with the packing.

In testimony whereof I affix my signature.

WILLIAM W. DEGLER.
