-1 3e1it'known thatLALFnED P. PERKINS, a c1t1zen of the United States, residing in the city of New York, borough of Manhattan,-

nd State of New York, have inventcoun a ed certain new and useful I rovements in m yeQh i gqf which the ibllowing is a specification;

to provide 1 baby-chair'vertica v to: an rd pense with the use and the invention.

This invention relates chairs'for infants, adapted to be removably inar chair, so as to disof t e usual highchair s has for its object mainly. proved means for adjusting the 11y with relation to its supto portable folding port and also to provide such a chair with safety and with seat and arms. other ends, which will hereinthe. invention consists in the inclination of t 1 To these and after appear, hovel features of improvement tion andarrangement o I hereinafter described and finally summarized g e e shown in view of a modifie safety-catch to sorted in in theap'pende Reference i gdr gs- .tlon, wherein (1 claims.

extend through the uprights, as

Through thes e slots pinsor spin d are adapted to slide theres. being attached to the the back-rest 5, the lower 6 being provided with.spind1e s 7,

which-enter said slot 2 and act as astay for said lower member 6, connecting members i or, rods 8 being also provided to betterstay the members 4 and 6; but the back-rest 5 may be dis ensed with, it being suflicient to provide a ame, adapted to slide between and alon the uprights 2 2, as will be hereinafter escribed. The spindles 3 extend through the, slots 2 sufficiently far to enable a screw-thread to be formed and to allow a wing-nut 9 to be operated thereupon.

It is evident from the foregoing that theslots 2 are for the purpose of adjustment of the chair vertically; Between the members 4 and 6 of the back-rest 5 spindles-1O are adapted to rotate, (see Fig. 3,) the said spin dles being provided at their extremities with reduced portions 11, adapted to enter suitable openings in the members 4 and 6. hook 1-2 is preferably formed integral with the said spindles, the object being to -ov1de a strong hanger for suspending the chair to a support, such as an or inary chair, and thus avoid rivets, bolts, or the like, which are hable to become loosened. A

' To avoid scratching'or marking of the support upon which the chair is hung, I cover the hooks 12 with a covering 13 of anysuitable material, suchas rubber, cloth, &c. As an additional means for safety, so as to avoid total dependence upon the nuts 9 for holding the partsin adjusted position, I provide the back-rest 5 with eccentric catches or the like 14, which are rotatably attached thereto by pins 15, the said eccentric catches belng provided with handles 16 formanual operation. These catches are positioned and shaped to automatically grip theuprights 1 1n the event of the loosening of the nuts 9 in the. manner of a roller-clutch. Theseat 17 is pivotally secured to the uprights 1 by means of hinges 18, Fig. 2, the seat being cut out, as at 19, Fig. 1, to partially surround the uprights. The arms '20 of the chair are also pivotally connected to the .uprightsl by hinges 21. Uprights 22 at the forward end of theseat connect the'seat and arms20, bemgpwotally secured thereto by hinges 23 2ft, respectively The arms 20 project sufficiently far beyond the uprights 22 to accommodate a I 5 Upon the bottom ofthe provide a lug or'block 26, which has a screw-threaded opening in which works a screw-threaded, s 'ndle or the like 27 the same having a km 28 for manipula-j' I 10 tion. The end of the screw-spindle 2? impinges upon an abutment 29, which s cru ried by the uprights 1,"the said abutment at ing also as a rest for the chair proper, masmuch as it tends to keep the chair in a vertlf cal position when hung upon an ordinary chair by impinging upon the framework thereof. .To prevent disfigurement of the 3 object upon which the said abutment imgom: description that my Improved chair i can e folded into a compact structure for lnges, I provide it with a felt cushion 30. A race 31, which extends between the upright 1, may also be provided to act as a rest in the manner of the abutment 29'and is faced with a felt or other cushion 32. The dotted lines B in Fig. 2 illustrate the manner of elevating the seat 17 by means of the screw 27 b simply revolving the screw against the al iutment 29, which tends to throw the seat upward. It will thus be seen that the child is more securely held, and'the elevating of the seat may serve other purposes. The connections existing between the seat 17, arms 20, and uprights 1 and 22 insure a parallel movement of the seat and arms relatively to each other. As an additional bracing means for the back of the chair I provide between the uprights 1 a cross-piece 33.

From the foregoing description it will be seen that my improved chair is suspended by hangers or hooks carried by the back-rest or vertically-sliding frame to which the chair proper is secured, itbeing understood that in practice what I have just termed the slidmg frame is, as a matter of fact, stationary when hung upon a support, such as an ordinary chair-back, and that the chair-back frame of my improved baby-chair is vertically adjustable thereupon without disengaging it from the support. By loosening the wing-nuts 9 and pressing downwardly upon the handles 16 of the catches 14 the chair can be raised or lowered to the desired position, whereupon the wing-nuts can be screwed up, the catches 14 caused to grip the uprights 1, and the chair is then seo'ure against displacement. The nature of the catches 14 is such that the will prevent the chair from falling if through neglector otherwise the wing-nuts are not securel tightened.

In the modi ed form illustrated in Fig. 6 the catch 14 is inserted ina slot 34 a little to one side of the slots 2, thus avoiding contact of these catches withfthe child.

Figs. 4 and 5 illustrate secondary downwardly-inclined slots or recesses 35, formed within the uprights 1 upon one side of the slots 2, which secondary slotsare adapted to receive the spindles 3 and 7. By this means slipping of the chair-back frame from its adj sted position in the slots is prevented, as the spindles 3 and 7, restin in the recesses 35, are securel held therein y the weight at; the child having the tendency to keep said spindles in the upper, ends of the recesses 35 in obvious manner. 'When it is desired to' adjust the chair having this form of the invention, the wing-nuts 9 are loosened, the "spindles 3 and 7 drawn out of their res ect1ve recesses and placed into the desired ones, and the nuts may be tightened again, when the chair is secure; but with .this form of the invention the nuts may be entirely dispensed with,'if desired.

Itwill be seen from the drawings and foreconvenience in storage or shipment.

It will be understood that many of the minor deta'ls of construction hereinabove descri ed ay be varied without departing from the spi or scope of my invention.
