'swine HANGER.

My linvention relates to hangers for porch swings and the like and has for its ob ]ect to suspend a hook from a bracket adapted to be secured overhead and to form a ball on the upper end of the hook for swivelly mounting upon a set of ball bearings arranged in the bracket whereby to produce a freely swinging hanger devoid of irritatlng squeaks of any character and which will allow swing to move freely in any direction, forward, backward, side to side and in a whirling circular motion. I

Another object is to provide a late within which the ball from which the ook 1s suspended is swivelly arranged and having an oil groove adapted to keep theparts engaged by the ball well lubricated.

A further object is to provide a device of this character which" is simple and strong 1n construction, easily'and quickly secured to a rafter or other object and Inexpensive to manufacture. f

@Other objects and advantages reside in the special construction,` combination and arj rangement of the various elements forming the invention as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof wherein like numerals refer to like Aparts throughout and in which Figure l shows my invention in use illustrating the radius `of movement of the hook,

Figure 2is a top plan view,

Figure 3 is a vertlcal sectional view taken along a line 3-3of Figure 2. Figure 4 is a detail of therafter attaching bracket, L

Fi re 5 is a view in elevation of the assembled anger employing the use of a bolt'for attaching to the rafter, Y'

Figure@ is a disassembled group view ofthe,

various parts comprisin the invention, and Figure 7 shows a modi ed form in attached position.

Referring now to the drawings wherein for the purpose of illustration I have shown a preferred embodiment of my invention I provide a hanger for porch swings and the like comprisinga pair of annular plates arranged in superimposed relation, each having acentrally aligned opening therethrough and se- .cured by lbolts or similar suitable fastening devices 5. The abutting face of each plate is providedwith a-concaved groove formed.

about the edge of the opening,'the groove in the lower plate 7 being of greater depth than the groove in the upper plate 6 and together combining to form an annular raceway for a set ofball bearings 9. The edge of the groove in the lower plate extends into a slight upturncd lip S so as to form a seat for the balls whereby to prevent displacement thereof.

Arhook lO is adapted to be carried by the plates by means of a ball ll arranged on the upper end of the hook and seated upon the ball bearings 9. rlhe ball ll is of a size to 'freely fitwithin the opening in the upper' plate 6 andthe upper edge of the opening is bevelled to form a groove l2 circumscribing the ball and'withinwhich a limited quantity of oil may -be placed for lubricating the ball and facilitate the free movement thereof.

The seepage of the oil around the sides of the ball will 'further operate to lubricate the ball bearings 9 and the seat for the ball bearings being slightly channelled by virtue of the lip 8 will retain the oil therein and prevent dripping upon occupants of the swing.

The edge of the opening in the lower plate is bevelled so as to provide the greatest possible radius of movement for the shank 13, of thehook.

Upon the upper face of the plate 6 is ar- ,p ranged a substantially U-shaped bracket lli vinvertedly arranged having its ends 15 turned outwardly at a horizontal plane and provided with openings for receiving bolts l5 whereby to secure the bracket to the plates. The intermediate portion of the bracket is also provided with an opening adapted to receive a lag wood screw 16 providing means for attaching the bracket an overhead beam or rafter 17. Y

After the parts above described have been i assembled in the manner illustrated in Figure 3 the ends of cables 18 from which a` swing is suspended may be placed over the hook and the device is then ready for use.

In Fi res 5 and 7 I have illustrated modified formsof the invention, the modification in Figure 5 comprising the substitution of a, threaded bolt 19 having a nut 2O arranged thereon as an alternative means of attaching the bracket to a rafter or the like, in such instance the bolt being inserted through an opening in the rafter anda nut `placed thereon to securely tighten the hanger in position.

In Figure7 the invention is shown-with the bracket omitted and the plates attached direct l of the ball 1l. Means for lubricating the ball and the ball bearings 9 is then provided by drilling a laterally extending opening 22 the" lower edge of the plate 6 and communieating with the recess and through such open,

ing a suitable lubricant may be inserted.

All parts or the hanger may be made oi iron with the lower plate and the ball on the end of the hook case hardened. These comprise the parts of the device that are subject' to wear and the case hardening thereof enables the useage of the same for many years, practically a life time. .ln the manufacture of the parts no welding orother process requiring the expenditure of a great amountof time is necessary.

lt is obvious from the foregoing that various changes in design and construction may be made without departing from the `spirit of theinvention or the scope ot the appended claims and l accordingly claim as rn own all such forms 'of the invention to-whic I am entitled.

.ll claim:

l., A hanger for porch swings comprisin a pair of plates arranged in superimposedre a'- tion and lixedlsecured to -each other and having a centra opening therethrough, a ball seated within said opening and having a hook suspended therefrom, anti-friction means carried by the lowerplate and swivelly su porting said ball said upper plate having tA e upper edge of its opening bevelledto form a groove circumscribin the ball and adapted to permit' the feeding or a quantity of lubricant thereto and asubstantially U-sha ed bracket invertedly arranged and attacha le to said upper plate and adapted to carry a screw for securing the same to a rafter or the like.1

2. A hanger for swings comprising a pair I of plates arranged in superimposed relation and tixedly secured to each other and having a central opening therethrough an annular flange formed at the lower end ot the opening of said lower late and forming a raceway be secured to said upper plate whereby to attach the same to a'rafter or the like.

`3. Ahanger forswings and the like comprising a hook, a ball formedon the shank thereof, a pair .of plates having a central opening therein, aball bearing raceway formedabout the edge of the opening in one of the plates Jl. g

and having a set of ball bearings fitted therein and adapted to swivelly support said ball,

`said raceway having an upturned lip formed about its edge providingan 'annular oil channel for the bearings, saidlother platehaving the edge of its openingibeveled and cooperat- -,ing with said hall' to form an oil rgroove around the -ball whereby to permit the feeding f a quantity of lubricant thereto and a subs'tantially U-sha bracket invertedly arranged .and atta able-to said upper plate for securingthe same tgan object overhead.v
