SAMUEL C. PANDOLFO, OF ST. CLOUD, MINNESOTA.

CHAIR.

'1 ,aoa'sss.

To (all whom it may concern:

Be it known that I, SAMUEL C. PANDOLFO, a citlzen of the United States, and a resident of St. Cloud, in the county of Stearns and formed so as to collapse or fold into com pact form when not in use. The invention has for its object the provision of a chairor seat which will be comparatively light in weight and at the same time possess theadesired strength and rigidity.

My invention comprises a chair or seat provided 'with a back or support adapted to fold parallel and into compact relation with the seat when the chair is collapsed or folded; while at the same timethe back or support will have such pivotal relation with the seat proper that its position will be maintained while the chair is in set up position.

The purpose of my invention is to provide a chair entirely made of metal and adapted to various uses, as for example, for camping, as an auxiliary seat in automobiles; and other like uses; which uses, and the advantages of my improved chair will be readily comprehended from the following detailed description of the accompanying drawings, wherein:

at the same time reenforces it and prevents.

The legs 12, 12 at a suitabletative movement during the setting up or collapsing manipulation of the chair. The rod 15 where it passes through the legs 12 and 16 1s preferably slightly reduced, as

shown at 17 in Figure 4, in order that the shoulder formed thereby will maintain legs 16, 1G in spaced relation with each other; and these reduced portions of the rod 15 are preferably provided'with small spacers or washers as at 18 arranged between each leg 12 and 16 so as to maintain a slight spaced relation between the legs, which enables a more easy manipulation or movement of the legs, while at the same time they will pre vent such rubbing contact between the legs, as would likely scratch or mar the latter.

' The upper ends of the le s 16, 16 are connected together by a suita le brace rod 19, which is adapted to be engaged and held by a suitable clip or lip 20 formed integral with the flange 11*at the front of the seat 10, as shown in Figure 2. The lip 20 is preferably bent slightly upward toward the bottom of the seat 10,-at a point intermediate of its ends, in order to provide a restricted passage therebetween for the rod 19 and thereby prevent the accidental movement of rod 19 past the clip or lip 20 and therefore hold the legs 17 in distended or set up osition. With the clip 20, like the seat 10 an flanges the bottom of the back;

' as at 25 beneath stood that the clip 11, formed of sheet metal, it will be under- 20 will possess sufficient resiliency to permit the rod 19 to be forced past the free end of the clip or lip and permit the latter to'spring back to normal position.

The flange 11 at the front side of the seat 10 is cut away at both ends, as shown at 20, to an extent commensurate with the thickness of both legs 12 and 16, in order that the seat 10 may fold into parallel relation with the .legs 12 and 16 when the chair is collapsed into the condition shown in Figure 3. The legs16, like the legs'12, are also provided at their lower ends with a brace rod 21 secured thereto in a manner similar to rod 14 in order to maintainthe proper spaced relation at the lower ends of legs 16; and this rod 21 is arranged to come into a different horizontal planefrom rod 14 when the chair is collapsed, so that the two rods will not interfere with a complete folding of the legs into parallel relation, see Figure 3. In order to permit such folding relation q'f the legs, the legs 16, at a po1nt adapted to register with rod 14, are each provided with a notch 22 adapted to receive the rod 14 of the legs 12 as shown 1 in Figure 3. The lower are preferably chamfered or rounded, as shown in Figures '1 and 2, in order that they may firmly rest, on the floor and at the same time preventing marring of the floor.

The pivots 13 at the upper ends of legs ends of the legs 12 also constitute pivotal pomts for the back 23 wh' ich'consists of sheet metal preferably provided with an upper rounded edge, while the side edges are each provided with a right angularly disposed and ta ered portion or flange 24 increasing in wi th toward the back being of such width as to permit the flanges to overlap the rear side of the seatlO sufiiciently to receive the pivot-forming rivets 13. The back 23. is so pivoted that it extends somewhat beneath the seat 10; and the lower ends of the flanges 24 are bent inwardly the seat, see Figure 2, so as to extend substantially parallel with the lower edge of the back. This bent portion 25 in turn has an upturned lip or projection as at 26 which is adapted to extend substantially parallel with and bear against when the chair is in set up. position. The bent portions back 23 if desired; although where sheet in raised position; while a be formed by severlng the lower ends 1 inwardly at right angles to b metal of proper thickness is employed, the lips 25 and '26 will have suflicient strength to obviate the necessity of welding the parts.

t is apparent from the construction shown and described that the back 23 will not only be held at proper inclination to the seat 10, but will be firmly maintained t t e same time the back 23 is'so secured that it may be folded forwardly and downwardly upon the seat 10 into parallel relation therewith, as shown in Figure 3.

Instead of constructing the legs of bar metal as shown in the drawings, the legs may be constructed out of strips of sheet metal bent longitudinally into channel or U-shape, as shown in the detail view in Figure 6. In order to prevent the legs having sharp lower ends or edges, the inter-- mediate or curved portion of the strips may be extended slightly beyond the channeled portion and this extended portion bent back between the sides of the channel as shown at 27 in Figure 6, thereb providing a closed end to the lower part of the legs and therefore a smooth surface which will prevent marring or scratching of the floor; and this ip or extension 27 may be brazed or welded in place if desired. p

I have shown and described what I believe to be the simplest form of my metal chair; but modifications may be made in certain details without departing from the-spirit of the invention.

What I claim is 1. A chair of the class ing a seat portion formed of sheet metal, three edges whereof are turned downwardly or flanged, with the turned edge at one end of the seat provided with an integral extension or lip disposed beneath the seat, a plurality of metallic le s arranged in pairs to extend in opposite d iagonal directions, the legs of one pair being pivotally secured to the turned downedges at one end of the seat and connected together intermediate of their ends by a tie-rod, the legs of the second pair being pivotally mounted at a point intermediate of their ends on said tie-rod so as to be disposed intermediate of the legs ofthe first pair, the upper ends of the legs of the second pair being secured together by a cross-rod adapted to be engaged by said 1i sition an thereby hold the second pair of egs in place, and a sheet metal back, two sides whereof are bent forwardly and adapted to overlap the sides of the seat, the two out sides of the back being pivotally mounted on the .pivots of the first mentioned pair of legs to adapt the back the seat, with the lower ends of said bent to extend beneath and have abutting ends of said first when the chair is in set up poto 'fold down onto mentioned pair of legs to support the back in raised position, the turned down edge of the seat provided with the integral lip being cut away to permit the seat and both pairs oflegs to fold into parallel relation when the chair is collapsed.

2. A chair of the class described, comprising a sheet meta-l seat, the marginal edges whereof are turned downwardly, metallic legs arranged in pairs, the legs-of one pair being pivotally secured to the turned down edges at the rear end of the seat, a cross-rod secured to said legs at an intermediate point, said cross-rod being shouldered at its ends intermediate of said first mentioned legs, the legs of the second pair being pivotally mounted at a point intermediate of their ends on said cross-rod intermediate of its shoulders and the legs of the first pair wherehaving flanged sides pivotally mounted on the pivots of the legs of the first pair and to the outside of the rear end of the seat so as to permit the back to fold down onto the seat, while the turned down edge at the front of the seat is notched to receive the legs of both pairs and permit the seat, back and both pairs of legs to fold into parallel relation with one another.
