invention relates to-swings andfit is one of -my objects to 'vprovide a swingV in which the idea of safety is paramount. An-

other objectr which I .havewinviewis the provision Vof' a swing whichgwhich may be easily actuated since'thediiculty of Sactu# ating swings ofthe present type' has been the greatest obstacle in popul-arizing" this type of swing. It is the thirdaobject of my invention to makethe swing very attractive tofchildren of alliages.I Having: in view these objects and others which `willibe men- Y tioned Vin the following description,ll `will now refer to the drawings,fin. which `V swing and its `support; y

The loopedp'ortion o f the strap 13 serves as va' bearing -for the'v swing and this bearing shouldbe made .as 'nearlyfri'ctionless yas. possible'bymeans of balls "or rollers or thev like. The bearingpin 'isshown at 15, and secured f tofea'chen'dgof thepin isa U-shaped. clipf 416.

The clip passes through a bracket 17 ,y and if it is desired to suspend the swing from a tubular support as shown in the drawings, a bent bolt 18 passing'v over the top of the support 10 the ceiling.`

The seat of the swing isshown at 19`and in this instance the numeral indicates the saddle of the wooden horse 20.

The swingis also provided with means for actuating it.` 'The yoke 22 basan upwardly and forwardlyextending portion. 22av for receivingf the' horses Yhead-during `them@- and rearwardly extending parts'22l, avr pair c ofrrearwardly-and downwardly extending l y' parts 22, twov parallel pairs 22d and 22e, the

"By vmaking'the pins'integral'withthe plates 26V f and securing the `platesto the .parts 22`,:both

ofthese diiiculties `are remedied. lThe stirrup. straps arelm'ade Aadjustable for the convenienc'e ofthe .ridergf v ,The arm 2 7 extends forwardly'land downz wardlyn from the bracketilf; being secured to frthe" bracket means .of the bolt .which secures the Abracket tofzthei supportl 10. The .armj 27-isfprovid'edat its forwardi end with f A ai pulley28; The-rope or cable29-isxsecur'ed through 'theleyezxof an eye .b'olt.80, this bolt serving also yfto secure the partsfll and112 lof the support. together.l The rope: for 4cable.4 k29 may. be extendedffto ythe syokel 22? but I prefer `portion of the vmember 22.v This motion is of course transmitted *through` the connections 29u Aand 29 to` the support 11, causing the swing to moveV on its pivot 15; It is Va considerable movement of the forward end CTI lreadily reach it with his feet'.

only the forward impulse that is given to the swing, the rearward movement being a Sim le aendulum movement but each for-y ward impulse will carry the swing higher than the preceding one. The pivots 23 are directly underneath the rider, and because of this construction together with the great leverage, the swing` may be actuated with the minimum of effort. yThis advantage is still further increased by the use of bally or roller bearings in the suspension of the swing.

Swings of all kinds may be provided with either a safe or a dangerous construction, and

vin my swing the safety features are of prii the parts, but safely is provided byso elevating the portion 22b that the child cannot One of the most serious dangers,however comes from the fact that any fiexible element 29 will become worn in time. The breakageof the rope 29 allows the Vforward end of the partV 22 to fall to the groundv where Vit is aptto suddenly stop the movement of the swing and to throw the occupant. This difficulty. is avoided in my swing by the employment of certain features of construction of the rear portion of the element 22 in combination with the seat 19. The saddle has laterally extending projections which lie in the projccted planes .of movement of the two parts of the element 22. The parts 22e are there- Vfor@ extended rearwardly of the pivots 23 a suliicientdistance so that the rear end of the element 22 will engage the projecting partsof the saddle tov limit the'downward movement of the front end of the'element V22. Breakage of the rope 29 will then merely ystop the actuation of the swing,

`which will then come to rest gradually and without danger to the rider.

Having thus described my invention in terms which will be readily understood by others skilled in the art to which itpertains, what I claim asV new and desire tosecure by Letters Patent of the United States is 1. A swing including a seat member and a rigid support extending upwardly therefrom, said support being adapted to be pivotally secured'at its upper extremity at afixed overhead point, a Vyoke pivotally secured to said seat member `an d lextending forwardly and rearwardlyfrom its pivotal connection, a pulley xedin position forwardly of said'support, a flexible connectionbetween the forward extremity of said yoke andthe upper portion of said support, said flexible connection Vpassing over said pulley, and an abutment on said seat member for engaging tne rearward portion Aof said yoke to limit the downward vvmovement of the. forward extremity thereof. v Y

2. A swing including a body memberand a rigid support therefor for suspending said body member from a fixed overhead supporting structure, a horizontalV pivotin said rigid support adjacent its upper extremity, a saddle on saidbody Ymember immediately to the rear of said rigid support, said saddle jecting therefrom, a yoke pivotally secured so i having laterally extending portions 'pro to said body member directly underneath said saddle andJ extending forwardly Yfrom its pivotal connection, a pulley fixed in posi tion forwardly Vof said rigid support, a flexible connection between the upperportion of said rigid support and the forward extremity of' said yoke and passing over said pulley, and stirrups depend-ing from said yoke atpointsforward of said rigid support, said yoke having portions projecting rearwardly fromY thev pivotal point of said'yoke, said rearwardly projecting por tions'of the yoke being adaptedgto engage the laterally projecting portions of the saddle to-limit the downward movement of the forward extremity o-f saidyoke.
