4 Claims.

This invention relates to improvements in playground swings, and more particularly to a new and useful swing support and means for attaching the various desired types of swings and ,5 exercising devices thereto.

An object of the invention is to provide an improved swing support formed with a horizontally disposed supporting bar with attached inverted V-type supporting legs formed with suitable 10 braces, said bar and legs being made of channel iron construction, while the bar is suitably reinforced with a wooden core and an overhanging wooden cap member.

Another object of the invention is to provide 15 an improved bar type swing and exercising device support adapted for use on out door playgrounds, or for use within doors, at which time, suitable rubber foot mats or pads will be provided, whereby the swing support will be retained 20 in substantially fixed position, but readily moved from place to place when desired.

A further object of the invention is to provide a metal fabricated swing support, which will be highly efficient in operation, and quite inexpen- 25 sive to manufacture.

Other objects will appear as the description proceeds.

Like characters of reference are used through- 10 out the following specification and the accompanying drawings to designate corresponding parts.

In carrying out my invention, I provide a channeled U-shape metal supporting bar I, which in 15 turn is provided with a wooden core 2, which extends nearly to the top of the said bar I. A T-shape cap rail 3, preferably of wood, is fitted into the upper portion of the supporting bar I, on top of the core 2, and is formed with the lat- 20 erally and downwardly extending side flanges 4, which serve to protect the core of the support ing bar from the weather, and to deflect and make any drippings from rain, drop off from the said flanges, and not drip on to the metal parts of the bar or the associated swing elements attached thereto. Suitable screws or other fastening means 5 will extend through the cap rail 3 and into the core 2, to hold the several parts of the supporting bar in assembled position. The supporting bar I will be held in position by means of the inverted V-shape supporting legs 6, made from metal channel iron which is U- shape in cross section. The legs 6 instead of extending downwardly at right angles to the supporting bar I, extend outwardly therefrom", as clearly illustrated in Figure 1 of the drawings. The ends of the channel supporting legs 6 are turned inwardly, as shown in Figure 3 of the drawings. Leg bracing members 1 extend between the inverted V-shape legs 6, and are also formed of U-shape channel metal pieces, and have their edges inturned as at 8, as shown in Figure 4 of the drawings. The bracing members I are also provided with the outwardly and downwardly extending fastening tongues 9, which are provided.- with perforations I0, through which suitable fastening bolts II extend, as well as through similar adjacent openings in the legs 6.

For the lower ends of the supporting legs 6, I have provided round foot members I2, formed with central struck up attaching ears I3, said ears being perforated at I 4 and adapted to receive suitable fastening bolts I5, which also pass through the lower portion of the said supporting M foot or base plate, and is adapted to have a positioning spike or other suitable fastener passed therethrough and into the ground, to anchor the swing support firmly to the ground. If the swing support is tobe positioned within the house, a suitable rubber non-skid mat will be placed under the foot member, said mat being shown by the reference character I1.

I have designated several different forms of swings and exercising devices'supported by the swing bar, and have shown two forms of pivotal connections between the swings and the supporting bar, one form being shown in Figures 5, 6, 7 and 8, and the other form being shown in Figures 9, 10, 11 and 12.

The upper ends of the supporting legs 6, are provided with the laterally extending bracing and reinforcing ears 30, which contact the adjacent surface of the supporting bar I, and also contact the underneath surface of the cap rail 3, and are held-in assembled relation with the 7 associated parts by means of the bolts 3| extending through the said ears, the supporting bar I and the Wooden core 2.

I provide a substantially T-shape bearing bracket [8 which is reinforced, and is formed with depending spaced arms 19, which extend through suitable openings (not shown) in the supporting bar I, and are connected by means of the bolt 20, upon which a nigrum bearing ring 2| is disposed. A hook member 22 is rotatably mounted upon the bearing 2!, and is adapted to be connected through the chain 23 to a swing seat 24. The other form of support consists of a U-shape bearing member 25 having laterally extending arms 26 extending in opposite directions, said U-shape portion extending through a slot formed in the lower wall of the supporting bar I, and is adapted to engage a chain or link 21, which in turn is connected with the ladder 28, or other suitable or desired exercising apparatus.

Many minor changes in detail of construction supporting bar, a reinforcing core therein, a protecting cap rail positioned in said bar and extending beyond the sides thereof, means for supporting said bar in spaced relation to the ground,

and exercising means suspended from said bar. 7 2. A playground swing comprising a U-shape supporting bar, a reinforcing core therein, a T- shape cap rail received within said bar and extending beyond the sides thereof, inverted V- shape legs at the opposite ends of said bar for supporting the same in spaced relation'to the ground said V-shape legs being formed with oppositely extending attaching ears engaging the opposite sides of said U-shape supporting bar, fastening means extending transversely through said U-shape bar and reinforcing core, the overhang of said T-shape cap rail protecting the composite rail structure from the weather, and exercising means suspended from said bar.

3. A playground swing comprising a U-shape supporting bar, a reinforcing core therein, a T- shape cap rail received within said bar and extending beyond the sides of the same, braced supporting legs attached to the ends of said bar and extending outwardly and downwardly therefrom braced supporting legs formed with oppositely extending attaching ears engaging the opposite' sides of said U-shape supporting bar, fastening means extending transversely through said U-shape bar and reinforcing core, the overhang of said T-shape cap rail protecting the composite rail structure from the weather, hearing yokes extending through said rail, and eXercising means attached to said yokes.

4. The subject matter as claimed in claim 3, and bearing rollers disposed between said yokes adapted to support the exercising means. 7
