CHAIR-GUIDE,

SP ECIPICATION forming part of Letters Patent No. 355,689, dated January ll, 1887.

(No model.)

To aZZ whom it may concern.-

' Be it known that I, GEORGE FELDKAMP, of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful my improved locking device; Fig. 2, a plan view of the same; Fig. 3, an enlarged side view, partly in section, with the locking mechanism; Fig. 4, an enlarged external View of the locking attachment, and Fig. 5 a plan View of the locking attachment'detached; and Fig. 6, a perspective view of themet-al piece forming the hinge.

This invention relates to an improvement in lockin g attachments for childrenshigh chairs, consisting of the guard hinged to the arm at one side of the chair, and connecting at the opposite side with a spring-bolt, so as to be held in position beneath the arms of the chair, the said bolt having a ring at its lower end, so as to be readily opened while the said guard rests upon the case containing-the bolt, which prevents it from becoming twisted or broken,

all of which will now be fully set forth.

In the accompanying drawings, A, Fig. 1, represents an ordinary childs highchair. The arm-support B is secured to the frame or seat of the chair as ordinarily constructed, and the upper end of this said support is provided with a metal case, D, fitted thereon, for which purpose the shoulder E, at its upper end, is placed lower down than ordinarily, instead of simply resting against the lower side of the arm F. This metal piece D, placed on the upper end of the support B, is so disposed as to have a flange,,G,' rearwardly provided with an opening, so as to secure it to the lower side of the arm F by means of the screw H.

This metal piece D projects forwardly from the support B, with its upper side provided with a rabbet, I, the thickness of the guard J. This forward part K of the metal piece D has vertical openings L, and is provided therein with a bolt, M, projecting up through the cross-piece M, having a ring, N, at its lower end, the upper end designed to project somewhat above the face of the rabbet I, forming a bolt or catch for the guard J; for which purpose a suitable opening, 0, is provided in the under face of the guard J.

A spiral spring, P, is placed on the bolt M, and interposed between the upper and lower faces of the forwardly-projecting part K of the metal piece D. The spiral spring P is secured to the bolt M, and to the upper part 01" the metal piece D, and has such a tension that the normal position of the bolt M is with its upper end projecting through and into the rabbet I, so as to engage with the opening 0 of the guard J. The arm of the chair having the guard J hinged thereto is provided with a metal piece, D, corresponding to theone already described, except that in place of the bolt M, extending through the forward part of the metal piece D, a fixed lug or stud, Q, is provided on the upper face of the metal piece and extending up to the under surface of the arm F, which receives the end of the'guard J, and thus acts as a hinge. Ordinarily these guards J are placed upon and hinged directly to the upper end of the support B,or are hinged immediately over the'arm; but, as will be n0 ticed, one of the features of my device is that the forward and laterally projecting sides of the metal piece D, in conjunction'with the under surface of the arms F, permit of the guard J swinging around beneath the arm without being liable of getting twisted or broken,

as in the ordinary guard.

In operating the device, the guard J being I hinged to one of the arms, it is simply swung around so as to come in contact with the shoulder of the rabbet I, where the vertical and the chair-arms F,combined with the metal piece D, fitted on the upper end of the support B, and the pivoted guard J, all substantially as and for the purpose described.

2. In a high chair,the metal piece placed on the upper end of the side support, beneath the arm, having a rabbet forwardly to act as a support for the guard, anda vertical bolt so the piece D under the other arm, provided disposed as to engage with the recess of the guard, substantially as herein set forth.

3. A childs high chair having a guard pivoted on hinge under one arm and recessed under the other end, combined with a metal piece under the other chair-arm, provided with a springbolt adapted to fit into said recess, all substantially as described.

4. In combination with the chair, the hinge piece D, having stud Q under one arm and with a spring-bolt, and the swinging guard J, 7 adapted to be caught by the said spring-bolt, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 20th day of February, 1886, in the presence of witnesses.

GEORGE FELDKAMP.
