UNITED STATES THEODORE ERNST, OF BAYFTELD, WISCONSIN.

NURSERY-CHAIR.

Specification of Letters Patent.

Patented War. 15, 1921.

Application filed August 26, 1920. Serial No. 406,218,

T 0 all whom it may concern Be it known that I, THEODORE ERNST, a citizen of United States ofAmerica, residing at Bayfield, in the county, of Bayfield and State of Wisconsin, have invented certain new and useful Improvements in Nurscry-Chairs; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to nursery chairs for use in a nursery, and one object of the invention is to provide a chair which may be used as a high-chair and which may also be used as a combined chair and table when turned to a lowered position. Another object oi": the invention is to provide the highchair with an improved type of tray which may be firmly held in place across the chair and may be entirely disconnected from the arms of the chair or only disconnected from one arm and then swung to one side where it will hang at the side of the chair. Another objectofthe invention is to so construct the tray and locking means that it may not move out of the proper position when in use. Another object of the invention is to so construct the latch mechanism for thetray that it may be easily movedto a releasedvposition but at the same timeso constructed that it will normally remain in an'active position and serve to very securely hold. the tray in place.

This invention is illustrated in the accompanying drawings, wherein Figure 1 'is a view showing the improved chair in front elevation;

Fig. 2 is a view similar to Fig. 1, showing the tray swung to one side and suspended from the arm rail of the chair;

Fig. 3 is a view showing the chair in side elevation with the tray in place;

Fig. 4: is a view showing the chair in side elevation with the tray removed and supported upon brackets carried upon the back Fig. 5 is a fragmentary sectional view taken on the line 5-5 of Fig. 1;

Fig. -6 is an enlarged sectional view taken on the line 6-6 of Fi 3 Fig. 7 is a sectional view taken on the line 7-7 of Fig. 6; r

' Fig. Sis a sectional'view taken on the line 8-8 of Fi 7;

Fig. 9 is a sectional view taken on the line 99 of Fig. 7;

Flg. 10 is a view similar to Fig. 9 showing a sectlon taken on line 1010 of Fig. 7.

This chair is provided with an improvement over the chair disclosed in my prior Patent #l,277,888, issued September 3, 1918. This prior patent shows the general arrangement of chair provided with the supporting structure which may be folded to a lowered position or used in the set up position and further shows the arms carried by the upper portion beneaththe chair seat and serving as locking means to retain the chair in the set up position. The prior patent does not however show the improved tray disclosed in the accompanying drawings and shows an arrangement of springs for the latching arms somewhat different from the present disclosure.

This chair is provided with a seat I having a back 2 and-arms 3. The arms and back are of a conventional construction and the seat 1 is mounted upon supporting legs 4c and 5 which have their upper portions 6 and 7 cut from the lower portion. Hinges 8 are provided to connect the upper sections 6 with the lower sections of the forward legs 1 and it will thus be seen that the upper portion of this chair will be hingedly connected with the lower portion thus permitting it to be swung out of the position shown in Figs. 3 and 1. The legs 1 and 5 will be braced after the manner disclosed in the prior patent and the legs 5 are provided adjacent their ends with rollers 9 which serve as supporting rollers when the chair is in a lowered. position. A cross bar 10 extends between the upper end portions of the legs 5 and serves as a bar for engagement by the latching arms 11 which are pivotally mounted upon the rod or pivot pin 12 and are connected by a cross bar 13. The latching arms are yieldably held in an operative position by the springs 14: which are connected to this cross bar 13 and with the crossbar 15 carried by the upper sections 7 of the legs 5 and the latching arms carry rollers 16 forming supporting rollers when the chair is in the lowered position. It will thus beseen that the latching arms will be normally held in an operative position but may be swung out of the operative position when desired. This portion of the chair is very similar to that which is disclosed in the prior. patent, the main difference residing in the arrangement of springs for retaining the latching arms in the operative position. The arms 3 are provided with head-rails or bars 17, and a rod 18 is connected with each of these head rails 17 and positioned to one side thereof as-shown in Fig. 7. 7 Each of these rods 18 has one end portion 19 connected with the side of the head-rail and has its opposite end portion bent to provide a side arm 20' which in its turn'is bent back toward the outer end of the head rail '17 and connected with, the free end of this head-rail. It will thus be seen that the rods 18' extend beyond the forward end of the head-rail of the chair arms. v

The tray :21 will extend transversely of the chair'and rest upon the head-rails 17 of the arms and has its end portions extended beyond the arms and its forward portion extending beyond the forward ends ofthe arms. The forward end portion of this tray is cut out to provide a recess or pocket 22 in which will be positioned a rod 23' having balls 24 loosely mounted thereon. A channel bar 25 is provided beneath each end of the tray to receive the rod 18 and these channel bars 25 have their inner flanges provided with notches 26 and 27. notches 26 are provided to receive the arms 20 of the rods 18 and it will thus be seen that the tray can be put in place and will rest back upon the head-bars or head-rails of the chair arms. Latching strips 28 are provided to releasably prevent the tray from being removed 'fro m the arms of the chair and each is provided with a handle 29 thus permitting the latches to be easily removed to an inoperative position when desired. The latches may have the specific construction shown inthe majority of the figures or they may have the modified construction shown in Fig.10. In the majority of the figures the latch has been shown in the form of an angle strip which extends longitudinally of'the channel bar 25'and is provided with arms or fingers'3'Q which extend between the channel bar and under-face of the tray and terminate in hooked end portions for engaging the end portions of a spring 31 mounted in a p0cket'32 formed in the under-face of the tray. The form shown in Fig. 10 is s'omewhat'similar except that instead of being' provided with an elongated flange for engagingthe rods '18 the latch has been provided with a finger 33 which extends through an eye 34: carried by the channel bar 25 and further the latching strip is provided with a single finger 35 which extends between the latching bar and tray and has hooked end portion engaging the central portion o-f'the'leafspring 36.

When this chair is in use it will'be set up as shown in the drawing and will be retained in this set up position by the latching The arms 11. The tray will be put-in-place as shown in Figs. 1 and 3 with the latches engaging the rods 18 and thus preventing the tray from slipping off of the arms of the chair. It will be noted that, the tray will thus be held against movement transversely ofthe chair or longitudinally ofthearms. l/Vhen it is no longer desired to usethe' tray 2 the latch connecting the tray with-one arm may be released and the tray swung'from provided with a pin 38 -which extends through one of the channelbars 25 and has a turned end whichextends out through the notch 27 of the channel bar. Therefore when the tray is in place behind the chair back and'the latchesreleased so that they extend across the chann'elbars' 25- the tray will be-securely but 'releasably held in place. The tray will thus be securely but releasably held behind the chair-back until it isagain desired to use the same. With thetray removed the chair may be left i i-the set-up position shown or the latches 11v may be released and the chair turned down to rest upon the rollers 9 and 16.
