HENRY H. PAINE, OF PHILADELPHIA, PENNSYLVANIA.

TRAY FOR CHILDRENS OHAiRS.

SPECIFICATION forming part of Letters Patent No. 318,131, dated May 19, 1885.

Application filed July 3, i884.

To all whom it 77mg concern.-

Be it known that I, HENRY H. PAINE, of the city and county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Trays for Childrens Chairs, of which the following is a specification.

My invention has reference to trays for babychairs; and it consists in certain improvements in the means of attachment of said tray to said chair-arms, whereby it automatically ad justs itself to chairs the arms of which are at different distances apart, all of which is fully set forth in the following specification, and shown in the accompanying drawings, which form part thereof.

There are certain makes of babys chairs in the market without trays, the arms of which chairs are made of bent wood, and from the nature of their construction the said arms are not a uniform distance apart in all chairs of the same make. It has therefore been diffieult to provide suitable locking devices whereby a tray might be secured to said chairs and automatically adjust itself to the difference in width, so that the manufacturer might manufacture the trays independently of the chairs and be assured that they would fit all chairs of the class for which they were designed.

The object of my invention is to overcome the above difficulty by the simple construction set forth in detail hereinafter.

In the drawings, Figure 1 is a perspective viewjof my improved tray for a childs chair, inverted. Fig. 2 is a side elevation of the same attached to a chair in which the arms are not rounded. Fig. 8 is a similar view, only in this case the arms of the chair are rounded; and Fig. 4 is a cross-section of Fig. 2 on line 00 w.

A is the tray, and is cutout at the inner edge, as at A, to fit the child and allow the sides to extend back to obtain a suitable hearing.

B are blocks of wood, having apertures I). O is a guide and retaining piece, and extends between blocks 13, and has the notches or slots D, which act as guides. E is a spring having loops c, the side arms, E, thereof extending through the slots D and terminating in locking-pins F, which work through the apertures b.

(X0 model.)

The length between the outer faces of the blocks B is made equal to or less than the narrowest space between the arms G- of the chairs, so that they shall it between the arms of any chair of this class. These arms have holes preferably cut in about half an inch, as shown in Fig. l, or they may be cut entirely through, if desired, and the pins F are drawn together, and aft-er the tray has been put in position they are allowed to expand and fit into the holes H, the said pins F being forced out by spring E more or less to automatically adjust themselves to suit chairs of various widths. \Vhen the arms G are straight, as shown in Fig. 2, the tray is supported horizontally by resting thereon; but when they are rounded, as shown in Fig. 3, then it becomes necessary to put blocks B upon the under side of the tray or extend out the guide-strip B, as indicated in dotted lines in Fig. 1.

\Vhile I have shown the pins F made integral with the arms E and spring E c, it is evident that they may be made independent and simply hinged to the spring; or, it desired, one of these pins F may be made fixed and the other movable.

The spring F, as shown, is made of bent wire, and is held in place by blocks 13 and guide-strip G; but it may be secured to the tray in any other suitable manner desired.

\Vhile I prefer the construction shown I do not limit myself thereto, as the details may be modified in various ways without departing from my invention.

I am aware of the patents to l'lownin No. 140,900, and Barnes, No. 213,610, and claim nothing therein shown or set forth.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-- l. A tray for a babys chair, having supporting-pins one or both of which are forced outward by springs, whereby they may automatically adjust themselves to chairs of different width, in eombinatton with said springs, substantially as and for the purpose specified.

2. A tray for a babys chair, having supporting-pins secured to or carried by springs, in combination with said springs, and guides to limit the movement of said pins, substantially as and for the purpose specified.

3. A tray for a babys chair, having sup porting-pins secured to or carried by springs,

in combination with said springs, and guides to limit the movement of said pins and support said springs to said tray, substantially as and for the purpose specified.

4. A tray for a babys chair, having supporting-pins one or both of which are forced outward by springs, whereby they may auto matically adjust themselves to chairs of different width, and supporting-blocks to fit up- 'on the rounded arms of the chair to hold the pins F, and springs E 0 .u, substantially as and for the purpose specified.

7. The combination of tray A, blocks 13, guide-piece 0, having slots D, pins F, and springs E c E, substantially as and for the purpose specified.

S. The combination of tray A, blocks 13, supporting-blocks 13, pins F, and springs E e D, substantially as and for the purpose specifled.

9. The combination of tray A, blocks 13, guide-piece 0, having slots D, supportingblocks B, pins F, and springs E e E, substantially as and for the purpose specified.

In testimony of which invention l. hereunto set my hand.

HENRY H. PATNE.
