The invention to be hereinafter described relates to improvements in standards for school furniture and the like.

One of the purposes of the inventions toV provide a lstandard which may be died out of and pressed from sheet'steelwith economy ofmaterial. Anotherv purpose of the inventionA isv to provide simple and efficient hinge means for the seat receiving arms.

v"lhe character of the invention may be best understood by reference tothe following description of one good-form thereof shown in the accompanying drawings, wherein:

FigrGa is a horizontalsection taken on line (5--6a of Fig. 1; Yand y j' v l y Figs. 7 to 19 are. views illustrating steps in the manufacture of thestandards. Referring/tothe drawings, the combination desk and seatconstrn'ction shown therein comprises a 'desk 1 which is supported on `and secured tothe upper ends of a pair of standards. 5. Each fof these standards. is died out of and Vpressed from. sheet steel or'othermetal as more' fnlly hereinafter described. Each standard has arms 7- anddivergent legs 9 .e0r which are curved 1outwardto `give them the proper spread. The 'armsand legs are formed Y with flanges to .stifen the'same. Located in.-

. termediately of. the arms and'legs is a body 11 which is ofch'annelformA and has a depressed panel 13 for ornamental and strengthening effect. i

Fitted into the body of the standard Vand forming a part of the Vchannel form and'having flanges4 17 which y5) may be riveted or otherwiseeecured tothe flangesof the body.

rPhe seat back 19 may be secured to the'front sides of the standards by fins 2O (Fig-6a) which enter a pair of oppositely inclined kerfs cut into the rear vside of the back and oblique to the plane -of the back, thereby to'hol'dthe back to the standards andprevent the same from moving laterally with respect thereto.

A pair of seat supporting arms 21 are diedy ont of andforined of sheet steel and have depressed, panels 23 for ornamental effect. At the upper edges of the arms'are flanges 25 to contribute to the stifness'of., the arms, and projecting obliquely from the flanges 25 are lins 27 adapted tolenter a pairof oppositely inclined kerfs 29`cut into the under side of the wooden seat 31 and oblique to the plane of thel seat. The construction is such that theY seat may be presented to thearms and slid along the flangesv thereof, so that the fins 27. will slide into the kerfs 29 and therebyhold the woodenseat down onto the arms and prevent Y web and marginal strengtheningflange 37 the arm 21. `The shoulder has a which isia continuation of the arm flange 25. To furthercontribute tothe strength of the arm, itmay have an inwardlyI projecting bote' he' arms provided.

tomflange 39. Each of with the panel or web 23 and flanges 25 andV 39 is'channelshaped in cr-oss-section. v Since the fin 27'projectsfrom the edge of the flange V25,-and the arm lis formed ofV sheet steel, the

liiange .and .fin have an y inherent resilienceV which contributesl to tight fit ofthe flnsin the kerfs in the seat.

Itis not always possible to cut kerfs in the seat of thesame'width as the fins, but by rela-V tively springingthe arms, the inherent resilience of the fins may be taken advantage of, and the' 'fins may be placed under tension so that they will press'tightly against walls of the kerfs.v Similarly by relatively springing thefstandards Ythe fins' on the front 1 flanges ico Vthereof may be placed under tension so that they will press tightly against walls of the kerfs in Vtheseat back. The standards will be has va cup 41 formed'in the web thereof,and

registering or maintained in the positions to which they are Y f sprung by .being secured to thedesk body 1.

Theshoulder 35 overlaps the body 11 and mating with a cup 43 formed in the web vofithe Kfiller referred to. A bolt 45projectsthrou'gh registering holes in' the oups 41 "and 43. InterposedV between theV cups'Y 1s a cup-shaped brass washer 47, and inter- 1 posed between the cup 41 and the nut of the Kbolt is a brass washer 49. Thesebrass wash` ers serve to prevent squeaking when the arms are rocked to raise and lower the seat.

A leaf. spring 51 is confined between the head Vof the bolt and the inner face' of the filler 15, thereby to exert ai pressure for causing the bolt to grip thecups 41 and 43 between the head and nut of the bolt with sufficient friction to hold the arms and the seat in positons OfKadjustment. vThe shank ofy the bolt is flattenedand projects through elongated holes in the'spring, the filler vcup 43 and the brass-washers, so as toV prevent Vturningl of the bolt and loosening of itsnut..l The hole inthe cup 41is lsomewhat larger thanthe shank ofthe bolt to allow enough'clearance topermit rocking of the arm.

K To limit the rocking movements of the arm,

K it is formed to'provide anV arcuate groove 53 which is struck from the center of the bolt hole Vinthe cup 41. A stop in the form of a j collar 55 is pressedfrom the web of` the liller.15, and

An important feature of the invention is the method practiced in the manufacture of the standard Kfrom metal stripstock of sub- .stantially uniformV width. This method is K y -7 to 19 inclusive, and corn- 1 illustrated inFigs. prises the following-steps.:V` Y Y K Addie 63V (Fig. 7) hasa iin 65 for cutting the slot 67to provide the legs yof the unit, and the die has provide the arms of the unit. The die is brought down to Vcut at intervals strip stockA of steel or other s uitablemetal, andin so portion of one unit and the end portion of the neKXt adjacent unit.

YThen the unit is pressed to form the flange 7 5 (Fig, 8) extending along one of the arms a fin 69 to cut outthev slot L71 to and one ofthe legs, and in the same operation the foot 77 is formed. Then by va similar operation the unit is pressed to form the opposite flange 79 extending along the lother arm and the other leg, and in this same operation the foot 81 is formed. i f K. l K

Next are formed the vpanel 83 (Fig. 9)- inl 'the portion-of the unit intermediate the slots 65 and 71, lthe panel 85 extending along the margins of the legs, andthe panelY 87 extend- Aing along the margins ofthe arms.

Then the unit 1s pressed to bend the leg 89 (Fig. 12) away from the other leg` v91,'and then Vwith a differently shaped die the legf91 is bent with a curvature away from the leg 89 so that it assumes the form in Fig. 13. One i of the arms 92 is bentV with a curvature away from the other arm; i

Then the feet are. trimmed and changed from the form indicated bythe dotted 'Kline 93 in Fig. 17 to the line V95 in said ligure. Y Theny the feet"v are pressed to provide the flange 97 (Figs. 18 and form indioatedby the full 19) and the countersunk portions 99Ywhich are" pierced to provide .theholes 101 through whichV the nails or screws areKinsertKed 'for f ysecuring the feet to the floor. 103.0f one of the arms of the standard is bent s othat it changes from theV form shown in K 'A Fig. 13Y to the form shown'in Fig. 16.

The last stepis thebendinggof'r the margin seat for securing'the seatto the standard.

readily apparent that there would Vbe great waste of material. K r K It will be noted that the flanges 7 K5 and 79 KK are .tapered with theirv greatest width V yj 'i This saving of material is an'important e'confV only. inKthe `manufactur e of these standards.` r f stock were required of'agfwidth equal tothe .127 Y distancebetween the tips of thefeet, it will be .Y

A (Fig. 19) of substantial length and enables the screw holes 101 in each foot to be located a suihcient distance apart so that when the feet are screwed to the loor lateral tilt of the standard will be eliectively resisted.

By this method a single piece of sheet metal may be formed to provide a channel-shaped body, angle-shaped divergent legs projecting therefrom with feet at the lower ends thereof,

a portion above the body for supporting a desk, and a member for receiving a seat back, the body being of suiiicientarea and form to cover the hinged portion or shoulder vof the lseat arm. The standard is not only strong and durable in construction, but also has a desirable ornamental design.

It will be understood that the invention is not limited to the speeiiic embodiment shown, and that various deviations may be made therefrom without departing from the spirit and scope of the appended claims.

What is claimed is: Y

1. In a standard, a single piece of sheet metal formed to provide a channel-shaped body, Vangle-shaped legs projecting down from the body and having flanges in the plane of the back of the body, and other lflanges perpendicular to said plane and longitudinally tapered so that the lower portions of said erpendicular flanges are materially wider t an the upper portions of said flanges, and feet pressed from the lower end portions of the anges of said legs and of substantial width for resisting lateral tilting oit' the standard.

2. In a standard, a single piece of sheet metal formed to provide a channel-shaped body, angle-shaped legs projecting from the body, and feet at the ends of said legs having a spread substantially greater than the width of the channeleshaped body a channel-shaped filler secured to said body, anarm having a portion for supporting the seat and a portion overlapping the body and filler, and hinge means for the arm including mating cups and a bolt projecting through said cups.

3.111 a standard, a single piece of sheet secured to the flanges of the channel-shaped bod an arm for su ortin a seat and means including a hinge connecting the arm with the ller.
