CHARLES N. EMMON$, OF DETRQIT, MICHIGAN.

CHAIR ATTACHMENT.

Specification of Letters Patent.

Patented Sept. 12, 1911.

Application filed January 16, 1911. Serial No. 602,804.

To all whom it may concern:

Be it known that I, CrrARLns W. Eir- MONS, a citizen of the United States, residing at Detroit, county of "Wayne, State of Michigan, have invented a certain new and useful Improvement in Chair Attachments, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to attachments to chairs and has for its object an improved attachment to childrens high chairs comprising a tray or table adapted to swing forward and downward.

In the drawings :Figure 1, is a side elevation. Fig. 2, is a side elevation of the arm to which the tray is secured. Fig. 3, is a perspective of the arm. Fig. 4:, is a perspective of the detached hook.

The chair 1 may be of any standard construction; the tray 2 is of convenient shape and is preferably provided with a raised rim 3. The brackets 4: upon which the trays rest are preferably of metal, each is pro vided with a standard 5 and a flange 6 with holes 7, through which are inserted the screws by which the bracket is secured to the tray 2; a hook 8 is pivotally secured to the bracket. The bracket is pivotally and slidingly secured to the seat of the chair 1 by a screw that is driven into the seat of the chair and passes through a long slot 9 in the end of the arm 4:; a spring 10 secured to the bracket 1 bears against the lever end of the hook and tends to force the bill end of the hook upward. This upward movement of the bill end of the hook is limited by a stop engagement which (as shown) is made by bending the sheet metal of which the hook is made across the neck of the hook from a to b. The cross web at the bent part engages against the edge of the bracket 4; a catch 11 secured to the chair arm is engaged in the notch of the hook; when the hook is made from stamped sheet metal a flange 12 is turned to form a broad bearing for the spring 10, and a flange 13 is turned to form a broad bearing for the finger on the lever arm side of saidhook when the hook is swung to disengage it from the catch. The tray swings on the pivot 14: and clears the foot rest 15; because of the slot 9 the tray can swing over the knees of the child. The brackets i are of length to hold the tray entirely clear from the chair arms and these are not scratched or marred by it. Lifting the tray does not disengage the hook from the catch 11.

The bracket, preferably made from stamped sheet metal is provided with two narrow slots 16, 17 that part of the flange 6 which is between the slots 16, 17 is bent to form a shallow loop and the end of the spring 10 forced under the loop thus formed.

The tray and its supporting brackets thus.

made can be attached readily to any arm high chair. The tray can be readily swung from its portion above the chair arm, but because of the character and manner of attaching the spring catch, it is not liable to be accidentally moved therefrom.

What I claim is 1. An attachment for chairs, having in combination with an arm chair provided with a catch on one arm, a tray, a bracket supporting said tray and adapted to swing the tray forward, said bracket flaring at its upper end, a hook pivoted to said bracket, the said hook comprising a sheet metal piece having on one side of the pivot a lever end provided with edges turned in to form flanges for a handle, the central portion being bent around said bracket so that the engagement of this bent portion with the flaring bracket acts to stop the hook, the other end portion being notched to form a hook engaging with said catch on the chair arm, and a spring adapted to hold the hook in engagement. with the catch, substantially as described.

2. An attachment for chairs, having in combination with an arm chair provided with a catch projecting from the sideof one of the arms, a tray, a bracket supporting said tray and adapted to allow the tray to swing forward thereon, the said bracket comprising a strip of sheet metal flaring at its upper end and bent into a flange to support the bracket, the said flange being cut and bent to form a loop, a hook pivoted to said bracket and comprising a sheet metal piece at one end having inturned flanges at the mid portion bent about said bracket so that the flare of the bracket forms a stop for the hook, and at the other end notched to engage about the said catch, and a flat spring fastened by being inserted in the loop of said bracket and at the other end engaging the upper flange of-the handle portion of said hook, the said spring thereby adapted to yieldingly hold the hook in en gagement with the catch and be grasped together with the handle portion and compressed to release the hook from the catch, substantially as described.

3. In combination with a chair having arms and a foot rest, the latter of which is an equal or greater distance below the chair seat than the arms are elevated above, a bracket adapted to be pivoted to the side ,of the chair seat and having a slot in which the said pivot engages, the said slot being of snfiicient length to allow the bracket to swingbelow said foot rest, a tray attached to said bracket, a catch attached to one of the chair arms, a hook having a notched portion adapted toengage the catch, pivoted to said bracket and provided. with a lever arm and a spring bearing against said lever arm, and. adapted to hold the hook in engagement with said'catch and remain in engagement during the possible reciprocat ing movement of said tray, substantially as described 4:. In combination with a chair provided with arms, and a foot rest, a tray, a pair of brackets screwed thereto and attached to pivots in the seat of said chair, the said brackets being provided with slots which engage over said pivots, a catch attached to one of said arms, a pivoted hook attached to said bracket having at one end a notched portion adapted to engage said catch and adapted to maintain engagement with said catch during the possible reciprocation of said tray, and at the other end having each edge flanged, the one flange furnishing a spring, bearing and the other flange furnishing; a finger grip, a fiat spring attached to the upper portion of said bracket and engaging against the flanged upper portion of said hook thereby pressing said hook into engagement with said catch, substantially as described.

5. In combination with a chair provided with arms, a catch projecting from the side of one arm, a tray, a bracket supporting the tray, the said. bracket "being pivoted to swing the tray forward from the arms, and i also adapted to reciprocate lengthwise the Copies of this patent may be obtained for five cents each, by addressing the Commissioner of .P'atents,

brackets, a hook pivoted to the side of one of said brackets and having a notched portion engaging the catch from below, the said hook having on the other side of its pivot a handle portion, and a spring connected to the tray and adapted to depress the handle portion, thereby thrusting the notched portion upward in engagement with the catch, whereby the tray is locked against swinging and the hook remains in engagement with the catch during the limited possible reciprocation, substantially as described i 6. In combination with a chair provided with arms, a tray, a bracket supporting said tray and pivoted through a vertical slot therein to the chair, the said pivoting being arranged to allow the tray to lift above the chair arms lengthwise of the slot and swing in an are described by such elongated radius, and means for locking the tray to the chair, whereby the tray in its forward swing may readily clear the knees of the child and the foot rest, substantially as described.

7. In combination with a chair provided with arms, a catch projecting from the side of one arm, a tray, a bracket supporting said traya'nd pivoted through a vertical slot therein to the chair seat, the said pivoting being arranged to allow the tray to reciprocate both the chair arms, assuming a longer radius than when resting above the arms and to swing through: the are of such elongated radius, a hook pivoted to the side of the bracket having a notched portion adapted to engage the catch from below and a handle portion forward of the arms, and a spring connected to the tray and engaging against the handle portion, whereby a reciprocable tray adapted to clear the childs knees and the foot rest, is securely locked against swinging and the hook remains in engagement with the catch during the limited possible reciprocation, substantially as described.

In testimony whereof, I sign this specification in the presence of two witnesses CHARLES W. EMMONS. VVitnesses':
