Mich.',-'-a corporation of New ersey 7 Application October 31, 193,8, Serial,No. 237,806 3 Claims; (ones-130) V The present invention relates torchairs, particularly such as are installed in'auditoriums, stadia, and the like; and its object is, generally, to provide an improved chair structure including chaplets whereby the hacker the chair is mounted on its supporting standards; and particularly, to provide such a structure and chaplets whereby the curvature of a row of chairs and the spacingv thereof may to a considerable degree be adjusted to meet the requirements of particular installations; and further, to provide in such a structure chaplets partially embedded'in, and thus firmly held by, therchairs cast-metal standards in the moldingthereof; and further, to provide an improved method for thus forming such standards and chaplets. Y c

These and any other objects hereinafter appearing are attained by the method and the illustrative structure particularly described in ,the body of this specification, said structure which constitutesa preferable physical embodiment of the invention being illustrated by the accompanying drawings, in which- Figure 1 is an elevational rear view of a por-'- tion of a standard common to a pair of chairs and portions of the backs of said chairs mounted on the standard by the chaplets;

Figure 2 is a horizontal sectional view thereof taken on line 2-2 of Figure 1;

Figure 3 is a vertical sectional view of the same taken on line 3-3 of Figure 2;

Figure 4 is a perspective View of one of chaplets;

Figure 5 is a front side View thereof;

Figure 6 is a plan view of the same;

Figure 7 is an outer end view thereof;

Figure 8 is a horizontal sectional view of the same taken on line 38 of Figure 5;

Figures 9, 10, 11, 12, 13 and 14 illustrate means and indicate the method for molding the chairs metal standard to partially embed and firmly hold the chaplets therein. In these views, Figure 9 is a sectional view of the molding pattern for the standard taken on line 9-9 of Figure 11;

Figure 10 is a sectional view of the pattern taken on line illl0 of Figure 12, and a rear view of a chaplet positioned thereon;

Figure 11 is a sectional view of the pattern taken on line I ll l of Figure 9;

- therein.

' Figure 14 Ba sectional view of the molded standardwith the chaplet in the sand of the mold, taken on a plane corresponding with that on. which Figure 12 is shown sectioned;

Figure 15 shows a'modified construction of the chaplet; and Figure 16 is a sectional view thereof on line I6 l6'of Figure 15.. c L I As illustrated by these drawings, the backs I of a pair of chairs are mounted on an intervening standard 2. having at its rear side a boss 20 with integral opposite horizontally extending wings 3 wedge shaped in horizontal section, the front sides 24 of the Wings being inclined laterallyrearwardly, as best seen in Figure 2, and the wings having medial depressions" whose bottoms 35 are parallel with said front sides.

' A chaplet 4 on each of the wings is desirably made of sheet metal bent to form at the chaplets outer end a bight portion 5, a forward leaf Band a rearward leaf. 1 which has vertically spaced, rearwardly extending and triangularly shaped portions. 8 with upwardly and downwardly extending flanges Brespectively. These leaves parallelly spaced apart have registering horizontally elongated j slots l0 'therethrough with surrounding inwardly turned flanges ll whose edges mutually contact. The chaplet is held in a closed horizontal slot l2 of the standards Wing 3 which registers with the slots ID of the chaplets forward and rearward leaves 6, l, the horizontal edge portions 26 of the ohaplets forward leaf seating in a pair of rabbet grooves l4 in the front side 24 of the wing 3, the flanges 9 of its rearward leaf seating in a pair of rabbet grooves l5 in the wings rear side 25 and the standard, when of cast metal molded as hereinafter described, extending around the chaplets flanges I l.

A bolt I6 extending through the chaplets slots Ill, the standards slot I2 and an opening H in the chair back secures the same in place, having a nut I8 which with the washer 19 contacts the rear side of the rearward leaf 1 which rests on the bottom 35 of said medial depression in the wing.

As illustrated, the standard desirably has opposite strengthening ribs 2| at its forward side and similar ribs 22 extending above and below the boss 20 at its rearward side.

The standard is desirably made of metal cast to partially embed and securely hold chaplets For thus casting the standard, a suitable pattern 23 therefor, shown in Figures 9-13, is prepared whose parts, corresponding respectively with the parts of the molded standard 2,

are indicated on these views by the same reference numerals, with prime marks added.

The chaplets 4 are applied to the patterns parts 3 (which correspond with the standards wings 3) so as to occupy the same relative positions that the chaplets and the standards wings occupy. To thus apply the chaplets to the pattern, each chaplet is slid into the open-end slot I2 of the patterns part 3 as indicated in Figure 13, the chaplets flanges 9 sliding in said parts rabbet grooves I and when the chaplet reaches its innermost position, the vertical inner edges 21, 28 of its parallel forward and rearward leaves contact at 29, 30 respectively the inner end 36 of slot I2 as best seen in Figure 12, thus closing off the space between the chaplets leaves and around their meeting flanges H, the horizontal edge portions 26 of the forward leaf and the flanges 9 of the rearward leaf closely seating in the rabbet grooves I4 and I5 of the forward and rearward sides 24 and 25 respectively of the patterns part 3 Said pattern with the chaplets thus applied thereto is used for molding the standard'with the chaplets partially embedded therein, by usual foundry methods.

The sand 32, 33 of a two-part mold is packed on the opposite sides of the pattern and around the chaplets thereon respectively so as to pass through the semicircular bottom 34 ofthe slot 12 and into the chaplets slots In. the molds parts being separated and the pattern 23 withdrawn, the chaplets remain in the sand, so that when the molds parts are assembled and the molten metal poured thereinto, the metal fills the space between the chaplets leaves 6, I and around the flanges II.

In its modified construction illustrated by Figures and 16, the chaplet 4 has the .bight outer end portion 5 and spaced leaves 6 l with medial slots (0 therethrough which have closed inner ends 35 and inwardly turned flanges H The chaplet is firmly held in the cast metal bodyl by being fused therewith in the casting of said body with the chaplet partially embedded therein.

The invention being intended to be pointed out whereupon,

in the claims, is not to be limited to or by details of construction of the physical embodiment thereof illustrated by the drawings, or of the method hereinbefore described.

I claim:

1. In a chair: a back; a standard having a lateral wing, the front side of the wing being inclined laterally-rearwardly and the rear side of the wing having a medial depression; a chaplet having forward and rearward leaves engaging the wings front side and the bottom of the depression respectively, the leaves and the wing having horizontally elongated registering slots;

means extending through the slots of the leaves and the wing for adjustably mounting the back on the standard.

2 Ina chair: a back; a standard having a lateral wing with an opening therethrough and front and rear inwardly diverging sides, one of said sides having a medial depression with its bottom parallel with'the Wing's other side; a chapletin the opening having spaced leaves engaging-one :side of the wing and the bottom of the depression respectively, the wing and the leaves having registering openings therethrough; means extending through the openings of the leaves and the wing for mounting the back on the standard.

3. In a chair: a back; a standard having a lateral wing with .an opening therethrough and front and rear inwardly diverging sides, one of said sides having a medial depression with its bottom parallel with the 'wings other side and having grooves parallel with the opening; a chaplet in the opening having spaced leaves engaging one side of the wing and the bottom of the depression in the wings other side respectively, the leaves-having openings therethrough registering with the wings opening, one of the leaves having upper and lower portions with oppositely turned flanges engaging in the grooves respectively; means extending through the openings of the leaves and the wing-for mounting the back on the-standard. i
