ATTACHMENT FOR INFANTS’ CHAIRS.

SPECIFICATION forrhing part of Letters Patent No. 646,084, elated March 27,1900.

Application filed July 15,1899. Serial No. 723,921. (Nomodel.)

To all whom it may concern:

Beit known that I, William E. Thompson, a citizen of the United States, residing at Roseville, in the county of Greene and State 5 of Missouri, have invented a new and useful Attachment for Infants’ Chairs, of which the following is a specification.

My invention relates to plate-holders generally, but is designed especially for applicaio tion to the table of a child’s high-chair; and it consists in providing the chair-table with an elongated slot, dovetailed notches formed in the sides of and near the respective ends of said slot, clamping-arms secured to the ta15 ble and which extend through the slot and provided with shoulders to engage notches to hold them in any extended position, the object of the invention being to rigidly secure a plate or similar article to the table of a child’s 20 high-chair to prevent the same and its contents from being accidentally thrown upon the floor.

In the drawings which accompany and form a part of this application, Figure 1 is a per25 spective view of a table of a high-chair with my invention attached. Fig. 2 is a perspective view of my invention detached, one of the supporting-arms being removed. Fig. 3 is a side elevation of one of the clamping-arms.

Fig. 4 is a top plan view of the clamping-arms and a detail cross-sectional view of the same on the line x x. Fig. 5 is a top plan view of a table of a high-chair detached.

represents the table of a high-chair of any 35 approved construction, through the center of which is cut an elongated slot 2, near each end of which is' a substantially - dovetailed notch 3, to be hereinafter referred to.

are spring-arms suitably joined at their 40 lower ends by welding or riveting, said arms being of light metal and crimped at 5 for a considerable distance. If desired, the arms may be roughened instead of crimped. The upper end of each of these arms is joined at 45 right angles to the body and bent around in a semicircular shape, the semicircular portion being bent to form a groove 6, running the entire length of said portion. (See Fig. 2.) is a clamping-ring loosely secured around 50 the arms 4 and adapted to engage the crimped or roughened portion 5 to hold the arms securely around the plate. The arms 4 are flared slightly at 8 (see Fig. 3) at their j unc_:ture with, the right - angle portion, thereby forming shoulders. 55 are supports, the lower ends of which are suitably secured to the lower ends of the spring-arms 4, asclearlyshowninFig. 2. The upper ends of said supports are bent at ah angle, as at 11, and provided with screw- 60 holes; through which screws pass to secure the whole to the under side of the table 1.

The clamping members being secured to the table 1, the whole is ready for use. If it is desired to hold the clamping members in an ex- 65 tended position, itisonly necessary to spring them apart until the respective shoulders 8 engage the respective dovetailed notches 3. A plate being placed between the clamping members, they are released from notches 3 70 and snap around the rim of the plate 12, and in order to rigidly hold them in engagement with the plate the ring 7 is pushed upward Upon the crimped or roughened surface 5 on the clamping-arms 4 until the grooves 6 are 75 firmly pressed around and over the rim of the plate, whereby the plate is firmly secured to the table against accidental displacement.
