HIGH CHAIR Filed oct. 18, 1928 ,ja/@22551 L Wm @y Patented Nov. 8, 1932 UNITED Yfrrnmr aoorENHAvERlor cmcAGoJLLrNois l .HIGH C3513 Application mea october 18.1928. serial No. 31:5;210.

The invention relates to high chairs for infants. Y i Infants, Vduring use oftheir highV chairs,

often stamp and exert considerable-pressure' for angularly adjusting the vfoot rest so ,that `the force required toexpandthe springs may4 be varied. i

f Afurther object of the' invention is to form i3 the foot rest as lan attachment which may be applied to chairs of differentconstructions and sizes, and is adjustable vertically relatively to the seat so that the foot rest may beV adjusted in a manner that is best suited to the requirements of the infant.

Other objects of the invention will be apparent from a consideration of the following detailed description.

The invention consists in the several novel 30 features hereinafter set forth and more particularly defined by the claims at the conclusion hereof. p

In the drawing: Fig. 1 is a perspective of a high chair embodying the invention. Fig. 2 is a plan view of the foot rest. Fig. 3 is a rear elevation of the back ofthe chair.

The invention is exemplified in connectionV with a high chair Comprising a seat l5; apair of front legs 6; a pair of rear legs 7 crossbraces 8 which extend between the legs;

ter of the present invention comprises a rectan gular member 13 which is provided at the uta rear thereof with a pair of pivotlugs14. The

lthestrips toslide therein. p has Ybeen found that ywhen the infant findsk vthat member 13 is resiliently supported, he or `she will operate the member Vas an exerou latter are disposed adjacent to the sides: of Y member 13 and are provided .with right angle flanges 15 which are secured to thebottomface of the member by screwsl.- The rear end of member-13 issupported by a rodd'iI which 55 f extends longitudinally of the memberand rhas its endsbent forWardlyand then inwardly to Y form pivotpins 17? which; pljtiinto. soc iets- 14a in lugs 14.;v Rod y1.7 is rigidly connected to the fr ont legs 6 of thechairfby a-pair of-'C- "60` Yclamps 18. The front legs-ofthe latter'are slidably mounted fon rod 17 so that theclamps may beapplied to cha-ir legs kwhich are spaced different distances apart.v Clamps 18 are 'secured-in their? assigned positions by set screws f9.5. 19. To prevent relative rotation ofclamps; 18 and'rod 17 the latterZisl provided with Vlongitudinal'grooves 20 into which the set screws extend. Therear legsof the clamps gare"providedwith-thumb screws 21 forsecur- 'im ing the clamps to the vchair legs. A ch-aracteristic of utilizing C fclamps for connecting rod 17 to the'legs of thechairis thatmember V13 may be readilypositioned vertically soasto- 75 -iit thelegs-of the infant.` l Member 1 3is supported at the front thereofgby'a pair of Aconnections 22; whichjl' extend upwardly between the trayfand arms ofthe Y Y chair kand are anchored tothe rest 10 'which' vformsja part-ofthe chairback 9.

If desired, a corrugated or ribbed strip 29 of rubber or any other suitable material may be secured to the top face of member 13 to prevent the infants feet from sliding or *Y falling off.

` In use, member 13 is adaptedV to bel applied as anattachment tov avhighchair of any type or size by sliding the C-clamps 18 around the legs of the chair and securing them in their assignedv positions byetightening set screws 19. Member 13 is then ade` justed vertically to iit the legs of the infant and secured in its adjusted position by tight? ening thumb screws 21. Connections 22 are .then secured in place by means of straps 27 and theirl length is adjusted by buckle 26 to bringmember 13 intoV theV desired 'angular position; If it' is desired to increasejthe forcefnecessary to operate member V13, connections 22 may be shortened so as to=in` crease the angle of member V13.
