NURSERY-CHAIR.

SPECIFICATION formingpart of Letters Patent No. 485,382, dated November 1, 1892.

Application filed June 10,1892. fierial No. 436,260. (No model.)

To all whom it may concern.-

I do hereby declare the following to be 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.

The invention relates to an improvement in chairs to which a childs table is attached.

It has for its object to provide a chair which will be simple of construction, inexpensive of production, and durable in-use.

With these objects in View the invention consists in certain features of construction and combination of parts of the same, which will be hereinafter set forth.

In the drawings, Figure 1 is a perspective view showing a high chair with a movable table attached to it and supported and securely held in place by means of my invention. Fig. 2 is an enlarged side elevation of my device, showing those portions to which it applies detached from the chair. Fig. 3 is an enlarged plan view of the bottom of a detached portion of the chair-seat, better showing my method of locking the table in position; and Fig. 4 is a similar View of the top of a detached portion of the chair, better showing the slot in the chair-arm and the position in the slot of the supporting-pin of the table-arm.

Similar letters refer to similar parts throughout the several views.

A represents those portions of the ordinary frame of an infants high chair which are not affected by my improvements.

B B represent the chair-arms, in which are placed the slots I I, preferably rectangular in shape, as shown in Fig. 2, for supporting the removable table C by means of the pins H, projecting inwardly from the upper part of the table-arms D D. chair-seat E are attached the pins F, adapted to engage with a slot G near the lower end of the arms D D.

In order to place the table in position it is To each side of theonly necessary to drop the arm-pins H into the slots I I, with the table slightly raised above the horizontal position, draw it forward to the position shown in Fig. 2, which brings the pins into secure engagement with the lower arm-slots G, when the table is dropped to its horizontal position ready for use. It will readily be seen that this simple method of adjustment of two sets of pins and the corresponding slots provides without more a firm and solid support for the table against any downward pressure and prevents any danger of displacement while the table is in a horizontal position. In order to lock the table in place, so that the child may not either accidentally or designedly remove it, as often happens with the removable tables hitherto used with infants chairs, I attach a single spring-catch K to the bottom of one side of E at d, provided with a shoulder 6, adapted to abut against the arm D when its slot G is brought into engagement with the pin F. K has a projecting arm I), held in place on E by the staple c, by means of which K may be readily pressed to free its shoulder e from D when it is desired to remove the table from the chair. I do not confine myself to this precise form of a catch, as the objects of my improvements might be attained by any convenient mode of locking mydevice to prevent its accidental displacement at the .lower arm-slot G, and a simple bolt attached to the under side of E in place of the springshoulder 6 would be sufficient for this purpose, though perhaps not so satisfactory; nor do I confine myself to the precise form of arm shown in the drawings, as the great advantage of additional strength and firmness in the support may be secured by the larger leverage of the table-arm secured by placing one of the points of support below the horizontal plane of the chair-arm. D might therefore, instead of being curved, as shown, project backward at an angle from the pin H and have its second point of support farther back on the side of E or even upon the rear vertical side of the chair-frame A; but the shape of the arms and mode of attachment and locking shown are perhaps as strong and convenient as any.

Having thus described my invention, what chair-seat, and a lock carried by the chair- I claim, and desire to secure by Letters Patseat to engage the table-arm at a point oppoent, issite to the slot therein to hold the table in The combination of a chair having arms position for use, substantially as set forth.
