j TO THE NORTHERN rnusr COMPANY Ann rrsnonn :e'osnwnnn As TRUSTEES ADJUSTABLE TABLE AND BENCH Application filed an is,

My invention relates to improvements in adjustable tables and benches and it more es-' pointed out in the annexed claims.

The purpose of my invention is to provide tables and benches in diflerent sizes for children or adults; that are simple to make; that are inexpensive that can be shipped in knock down condition; that are easily assembled; that are readily adjusted'to different heights andthat may, if desired, cooperate'with educationaldevices which can be assembled on the table by sliding ontothe table top or otherwise. j With these and other ends in view I illustrate in theaccompanying drawing such in-' stances of adaptation as will disclose the broad underlying features without limiting myself to the specific details shownthereon I ma use any desired cooperating features which lend themselves to the accomplishment of my purpose. The table top anddra-wer" anddescribed herein.

Fig. 4 is across section in plan of an adjustable leg and connecting clamp.

FigJ-5is an elevation in section of madjustable leg in its assembledrelation to'the top anda foot.

Fig. 6 is a plan view in section of an ad-' justable leg showing a crossbar attached.

These parts are so arranged that the entire table or bench may be easily set up by an inexperienced person. By resasonof this, it is possible to have the tables or benches delivered directly to the users home at small transportation charges. Another important feature is making the I tables and benches adjustable to varying heights 'and in burying the guiding plates which hold the adjustable portion in proper alignment with the stationary part of the sup- Whether a table top lor a bench seat 26 is ference-being that the parts required for *bench are. smaller 111 slze when the bench is to be used Wltll'l given size of table. Otherwise, if the benchis tobe used independently of the'table, its minimum height and length may be whatever the. exigencies of actual use may demand. In a similar sense, the table itself may be proportionately increased or decreased in size as desired. 7

On the under side of the table top 2 or the bench seat 26, side rails 2 are attached byme ans of screws. When these rails are attached to a tabletop they have a drawer ledge formed 011 their inside top corners on rails 2 are ordinarily attached toa seat-26 viously theledges 5 will be omitted. On the -'other hand, if a drawer should be desired he supported on ledges formed on side rails 2 in a similar manner to' the use made of; such ledges on the table.

The side rails 2 are mortised at 1 to receive the tenons S of the sliding support 7. These parts may be glued to each other or ermanently secured in any other manner. lhe sliding supports 7 have holes 10 by means of which the table top may be held at difterent heights on the table legs 13 and 13a. Guide plates 9 are driven into lengthwise grooves formed in the edges of the support 7. These guide plates slide in grooves 14 of the legs 13 and 13a, which construction leaves the outside faces of the supports 7 and the legs 18 and 13a flush with each other. The upper ends of the legs 13 and 13a are drawn toward each other against the sliding supports 7 by means of clamps 19. These clamps are .U- shaped so as to permit the legs 13 and 13a and the support 7 to be positioned between the side members of the clamps. The clamps 19 are pivoted at 20 to the extreme upper ends of the legs 13a and are provided with clamping thumb screws 21 which are sea-ted in bushings 22 that are imbedded in the upper ends of the legs 13. Bolts '23 pass through openings 10 of the supports 7 and through suitable openings in the clamps 19 so as to firmly hold the table in different height adjustments. lVing nuts 24l ion the outer ends of the bolts 23 serve to hold the bolts 23 in position. These bolts have square shoulders under the heads which engage slots in the clamps 19 and are thus prevented turning while the wing nuts 24 are put into place.

The feet 11 for the table legs are mortised at 12 to receive the tenons 16 of a pair of legs 13 and 13a. They are joined at their lower ends by tie blocks 15 which maybe permanently secured to the legs by gluing, the use of corrugated fasteners 27 or they may beheld rigidly connected to each other in any other manner. When so assembled, :a pair ,of legs 13 and 13a with a tie block 15 comprise a single unit to be assembled with a single foot 11 by means of the tenon 16 entering the mortise 12 where the parts are permanently attached to each other by gluing orvotherwise.

The use of clamps 19 overcomes and avoids the necessity of extreme close fitting of the supports 7 and the table legs. In addition, all tendency to wobble of the supports 7 in the legs, is overcome through the use of the clamping screws 21. In thessteps ofmanufacture the grooves 14 on the inner edges of the table legs are usually sawed throughout their length and, if desired, short metal plates similar to the guide plates .9, may 'be inserted in the grooves 14: fatathe lower ends of the -legs and such short length plates may enter grooves formed in the blocks if such additionalreinforcing is desired.

A pair of feet '1; are held vspaced .apartzby a foot rest or cross member 17, the ends of engaging;

which are seated in vertical gains formed in the tie blocks 15 where the parts are held in assembled relation by screws 18.

In knock-down shape, the table top 1 is separated from the under rails 2. A rail 2 and a support 7 form one of a pair of units; a pair of legs 13, 13a and a foot 11 form one of a pair of leg units, while the drawer 6 and the cross member 17 form independent units.

All of these may be packed together in small space and placed in a carton to be sent by parcel post or otherwise.

If desired, side springs may be attached to the drawer as shown in Fig. 7 to overcome any tendency to slide too freely should the table to t'he heles 10, eyelets shown in 'llig. -ilmay be used if desired.
