TABLE i-kTTACl-ZEJIENT FOR SEATS.

T 0 (iii whom it may concern:

Be it lrnown that l, "d rnl 1 l3. Cocoon, a citizen of the United States residing at Chicago, in the county of Cool; and State of lllinois, have invented a new and useful Table ilttachnient tor heats of which the following is a specification.

This invention relates to improvements in table-attachments for seats, ant pertains more especially to a vertically adjustable table-attaclnnent which has its table adjustable at dillerent angles to a horizontal plane as required to render the table suitable for reading, drawing etc.

She object of this invention is to produce a highly practical table-attachment which 'cids interference with the requisite l: eeroom for the occupant of the seat provided with the tab e-attachment.

Another object is to render said tableattacl'nnent transportable in a knock-down condition, and to facilitate the assemblage of its component parts and tie manipulations requiren for a readjustment oi the table. 7

Another object is to render the table-attachment attractive in appearance and simple, strong and dura' is in construction.

lVith these objects in view, and to attain any other object hereinafter appearing, this invention consists in certain res 0t construction d combinations and relative arrangement of parts, hereinafter described in this specification, pointed out in the claims, and illustrated in the acconi aanying drawings.

In said drawings, Figure 1 partly in section and partly is a sine view broken away,

of a table-attachment embodyingrny invention. 2 is a horizontal section taken Fig. 3 1s a vertialong the line 2 2, i. U cal section taken alon tiie line 33, Fig. 1. Fig. 4 is side view or the upper portion of the table attachrnent and shows the table at an angle to a horizontal plane, whereas in Figs. 1 and 3 the table is shown horizontal.

In said drawings A indicates two forwardly and rearwardly spaced substantially vertical members which are preferably of wood and rendered rigid in any approved manner with the framework of a seat and arranged at t is forward end and right-hand side edge of the seat-proper B which preferably of wood and at said side edge has a forward extension 5 to which the uprights Specification of Letters Patent.

A are glued or otherwise secured. One of the members A preferably forms aforward leg of the seat. The members A form a substantially vertically arranged slideway engaged by a substantially vertically adj ustable standard C which is preferably of wood and (see Figs. 2 and 3) engages the outer portion of the space between said slidewayforming members and overlaps the laterally and outwardly facing sides of the said slide- "ay-forriing members.

Means for se tiring; the standard C to the members A in the desired vertical adjustment of the standard are shown as coinprising a clamping bar 7, a bolt 8 and a nut 10, all relatively arranged and applied as shown more clearly in Fig. 2. Said clamping means are preferably arranged lower than the seatproper l3. lhe bar 4 extends transversely of and somewhat into the space between the members A and overlaps the laterally and inwardly sides of said members. The bar 7 is shown provided between the members A with two substantially horizontal and parallel laterally extending dowel-pins 12 which are spaced transversely of the standard C and project into holes 13 formed in said standard. The bolt 8 is sul stantially parallel with and arranged substantially centrally between said pins and has its head overlapping the laterally and inwardly facing side of the bar 7 and has its shank extending laterally and loosely through said bar and laterally and loosely through the standard C and beyond the outer side of the standard. Preferably the standard C has its portion which is penetrated or entered by the bolt 8 and dowelpins 12 reinforced at its outer side by a wooden cleat 14; glued or otherwise secured to the remainder or body and forming a part of the standard. The shank of the bolt 8 extends or course through and outwardly beyond said cleat. The nut 10 is screwed onto said shank at the outer side of said cleat, and a washer 15 is interposed between said nut and the cleat. Obviously a. manipulation of said nut as required to withdraw it from the washer l5 renders the standard 0 free to be readjusted, and manipulation of said nut as required to press said washer against the standard results in clamping the standard against the laterally and outwardly "facing sides of the slideway-forniing members A and in causing the bar 7 to clamp the opposite sides of said slideway-forming member, so as to secure the standard to said slideway-i orming members in the desired vertical adjustment of the standard.

At the inner side of the upper portion of the standard C (see Figs. 1 and 3) is a bracket D consisting preferably of a laterally facing substantially vertical cast metal plate arranged in proximity to said side of the standard. A suostantially horizontal bolt E, shown arranged centrally between the upper end portions of the slidewayforming members A and substantially parallel with the hereinbefore mentioned bolt 8, has its head arranged at the outer side of the standard (I and has its shank extending laterally through said standard and laterally through the lower end portion of the bracket l) and laterally through the lower end portion 16 of a substantially straightmetal brace G and inwardly leyond said brace. The brace G extends laterally or" and inwardly from the plate D and forwardly in relation to the seat-proper D. The bracket 1) and the brace E extend upwardly above the standard C, and H indicates a desk-top or table extending over and seated on the upper end of said brace and extending over and scared on the upper end of said bracket.

The standard C and the bracket l) are shown arranged under the table H adjacent the right-hand side edge o1 the table, and said bracket is secured at its upper end, preferably removable by screws 17, to the table. The brace G is shown secured at its upper end, by screws 13, to the table H. The bracket D and the brace G are rotatably mounted on the bolt E, and a nut 20 is screwed onto the shank of said belt at the laterally and inwardly facing side of the lower end portion 16 of the brace. A washer 21 is shown extending circumferentially of the bolt E between the bracket D and the standa "l C, and a washer 22 is shown interposed between the head of said bolt and the standard. The nut 20 prevents displacement of the brace G oi'f the shank of the bolt E. Obviously the bolt E pivots the bracket D and the brace G to the standard (1, and the lower end portion 16 01": the brace is seated, below said bolt, on a. flange 23 formed on said bracket and extending circumferentially of said bolt and embracing said end portion of and forming a seat for the brace.

' The table H (see Figs. 1 and 3) is provided over the standard C and at the standard-facing side of the bracket D with a recess 25 extending forwardly and rearwardly of the table and engaged by a metal section it which is secured by screws 24: to and forms a part of the table. The standard 0 has a curved top which is concentric relative to the pivotal bolt E, and the standard is shown provided at said top and centrally between its sides with an upwardly projecting tongue 27 which extends from the forward edge to the rear ed e of the standard and circumfer- 'entially of said bolt and is concentric relathe under side or bottom of the section it.

The standard C is provided at each side of its tongue 27 with a curved top surface 29 extending from the forward edge to the rear edge of the standard and arranged concentrically relative to the pivotal bolt E. The metal section it is seated at the sides of its groove 28 on the top surfaces 29 of the standard. Hence the table has bearing at each side of said groove on the standard. The tongue 27 and the side walls of the groove 28 coiiperate in preventing displacement of the table laterally of the standard. By the construction hereinbefore described it will be observed that the metal section it straddles the tongue 27 on the standard, and the tongue-straddling portion of said section extends farther circuinterentially oi": the pivotal bolt E than the top of the standard and covers said tongue and the surfaces 29 in any adjustment of the table circumferentially of the pivotal bolt E.

Means for securing the bracket D, and consequently the table H, in the desired adjustment circum'terentially of the pivotal bolt E are provided and arranged between said bolt and the upper extremity of the standard G and preferably farther from said bolt than from said extremity and (see Figs. 1 and 3) comprise a bolt 31 and a nut 32 which is in the form of a hand-wheel. The bolt 31 is substantially parallel with the pivotal bolt E and has its head arranged at the laterally and inwardly facing side of the bracket l) and has its shank extending through a curved slot (Z formed in the bracket and laterally and loosely through the standard C and beyond the outer side of the standard, and the nut 32 is screwed onto said shank at said side of the standard. A washer 33 is interposed between the nut 32 and the standard (I. A.washer 34 extends circumferentially of the bolt 31 between the standard C and the bracket D, and a washer 35 is interposed between said bracket and the head of said bolt. The slot cl is arranged concentrically relative to the pivotal bolt E. Obviously a manipulation of the nut 32 as required to render the bracket D free to be readjusted permits readjustment of the table H and brace G circumterentially of said bolt, and the bracket and consequently the table are secured to the standard in the desired adjustment upon a manipulation of said nut as required to clamp the bracket to the standard. The bolt 31 and one end wall of said slot cooperate in limiting the adjustment of the table circumferentially of the pivotal bolt E in one direction, and the other end wall of said slot and said bolt cooperate in limiting the adjustment of the table circumferentially of the said bolt in the opposite direction. The relative arrangement of the parts is preferably such that when the table is in a substantially horizontal position the slot cl has its end wall which faces in a forward direction relative to the seat-proper l3 cooperating with the clamping bolt 31 in limiting movement of the table in said direction. Fig. l shows the table adjusted at an angle to a horizontal plane.

By the construction hereinbefore described it will be observed that not only is a standard C arranged at the forward end and one side of and rigid with a seat, and. a table H provided forward of and above said seat and adapted to be supported wholly from said standard, but that a bracket D is arranged at the laterally inwardly facing side of the standard and extends downwardly from the under side of the table, that the table extends over the upper end of and is rigidly secured to said bracket, that the table is also rigidly secured at a point spaced laterally inwardly from the upper end of the bracket to and extends over the upper end of a diagonal brace G which is arranged wholly under said table at the laterally inwardly facing side of the bracket and extends from said point downwardly and toward the lower end of the bracket and has its lower end arranged opposite and next said side of the bracket, that the axes of the brace and bracket are therefore coincident, that the bracket and brace are adj ustable circumferentially of the axis of said pivotal member, that the table is therefore adjustable circumferentially of said pivotal member, that means are provided for securing the bracket to the standard in the desired adjustment of the table circumferentially of said pivotal member, that the upper end of the standard has the contour, dimensions and arrangement required to permit readjustment of the table circumferentially of said pivotal member and to permit the table to have bearing on said end of the standard, that the clamping means for clamping the bracket to the standard in the desired adjustment of the table circumferentially of said pivotal member are arranged between the table and the axis of the bracket, that the bracket is provided under and next the lower end of the brace with a flan e extendin circumferentiall of and D C! J concentric in relation to said pivotal memher, and that the relative arrangement of the parts is such that the hereinbefore stated objects of my invention are successfully attained.
