Letters Patent' No. 86,644, dated February l?, i869; vreissue No. 3,686, dated October- 26, 1869` nar-Royen seines-FRAME.,

Tha Schedule referred to in theme Letters Patent; and making part of the same putting together and takinga-part thetslai's and frames as the seasons change; and the object ot' my present invention is not only to avoid the luse of the objec-v tionable woodscrews, and to nlndfacility in attaching together and taking apart the slats and frames,

-but to allori, also,'a.nwrel simple, inexpensive, reihible, :1nd durable inode of compressing and iirn'ily hohling together lhe said slats ami frames, and preventing any oblique movements oi' the one upon the other iu The ti|st' part of my invention relates to the eombination of the wooden slats with the iron end-frames of the settec, by means of a series ot' projecting slopesided studs on the frames, and correspondingly slopesided or under-cut holes in the under sides ofthe slats, in such a manner that when the said slats :ne laid flat upon the said frames, with the studs oi" the latter in the. respective holes ofthe former, and the slats then slipped along and pressed iiixnly itl-the proper direction of their lengths, across the trames, the said slopes of the two parts will thaw the slats undframes into closer Contact, with a firmness proportie ate to the longitudinal pressure g-ivcn to the slats; tl'e objectief this part of my invention boing to afford a more simple, etiloient, and reliable mode of drawing the fiat contact sui-times of tliesaid flames und slats together. The second 'part ot' my invention relatos to the cpmr hination of grooved abutting-plates, having projecting slope-sided studs inserted respectively yin oorreepomh ing slope-slded or underwrit. holes in the, under sides ot' the slats, with grooves in the respective sides oi' the end-frames, and a key-wedge fitted therein, so-that by driving the Said wedge simultaneously into both of the respective grooves of the plate and frame, the inclined or sloped side of the stud on the frame and ofthe stud on the plate, will he forced further apart or against slopes ot' their respective slopesided or under-cut holes in the ulat, so as to securely and rigidly hold the said slat and frame together.

Descpt-ibn of the Accompanying Drawings.

Figure 1 is an elevation, showing the inner side' of one ot' the two corresponding cast-iron end-frames of .thc seti1ee, with transverse sections of two of the wooden slats applied thereto;

vFigure. 2, a plan view of the upper side oi' one of the wooden slats, with sectional plan views of the supl porting faces of the tno ond-frames ofthe sett-ee;

Figure 3, vertical transverse sections ot the sup-V porting-rib of the frame and of the key-wedge, in conuection with vertical longitudinal sections oi' the abut@l ting plate, studs, and sint; and' Figure 4, a. modification of the device for drawing and holding firmly together the sloping sides of the studs and ofthe holes in the slatsj y General Description. The end-frames :A A are inteudeilto he onn open or skeleton style of' construction, for the purpose of givin lightness with strength, and the edges or iii/(ies` to w lich' the wooden sia-ts Tl B are directly secured.

are cast in the well-known T-i'orm in their transverse sections; and along in the mill-width ot' the fiat-face surface ot` eaeh,tl1e series of studs ala project at proper distances apart, to receive over them th wooden slats B, which form the seat and hack otfthe settee,

Each of these studs if is, in height or length, about equal to twothirds of the thickness of the slats, and

the upper end of each one in the serios of the riesnective frames projects laterally, in respect to its fra-Ine, so as to form ou the projecting side an inclined plaine 2, or sloping surface, the series of said slopesidefi studs of each of the. two'frames, A A,.incliu ing or sloping toward contrary sides of the respeotiyo frames. l

In the under side, near each end of each of the slats B, a hole, 5, is bored sutllciently large sud deep to readily receive within it `any one of the studs?, and the side of the hole which is inteudedrto eoine in i" n;

tact with the inclined or slopingsitleef the signifie" underwent or sloped to correspond, in its direction or inclination with the inclination or slope the stud, so that when the two inclined surfaces or planes are pressed together by sliding the slut which covers the stud in the proper direct-ion oi' itslcugth, across the frame, the inclined or sloping surfapes will slide upone'fwh other,'and thus draw the slat'll and the frame into closer contact with each other.

At a short distance from the hole 5in the Slat, other like hole 7 is made, hutwith its sloping or under.

cut side inelining in a direction directly opposite to that of hole 5; and connected witlrthis hole 7 -is the abutting-plate E, whichy has ou one side a projecting slope-sided stud, e', (like the stud a,) to correspond with -the hole 7. i v

' In one end of this plate E there is a groove,8, which corresponds' with a like groove, 9, in that side of the frame A, and in th'se tw grooves a key-wedge, lil),

'isyiitted, sothat by driving the said wedge tightly in between them, when the studs e' and a' are in propel:

connection with their respective hoies 7 and 5, in the sint, the plate E will serve as :mahnt-ment, ami canse the slab to be drawn into closer und rigid Contact with the iurtiwes of tlie jz|me A :ind `plate E, and nonsequently serve the double 'purl'mse of holding the slut 15 tightly against the frame A, and preventing any diagonal r oblique mntions in respect to the ceunectvd frames and slats nf the' settce. A

As a inodificatifm of the abutment-plate E and wedge A10,1`or drawing and tightening together the frame A and slt, B, n curved dmwfboit, G, may be usel. For this purpos, :i :slot or hule, 3, is made tllmugh the sident' the:` fname, at a, point dircatly be! v low in' bvhimi the stud so that when 'he one end of the curved holt C is screwed into the under side oi' the sint, as indicated in tig. 4, the other and can in; tilriti into the hole 3, and a, screw-nut, c', applied anni scwwed up againt the 'side of the frame, so as w rdraw and hold tightiy tagt-ther the said shit mulfmne; .but as thin modilication svrves nly to draw inni hohl the two parte tightly wget-her, :he abuttingplate and key\vedge, shawn in fig. 3, is preferred, as it srvn the additional purpose of preventing, at the game' time, :my diagonali ur oblique motions in the sllathsyin respect tn the 'raines, in using the settee or moving 1t about.

Claims.

1 claim, as my inventionl. The combination of the slope-sided 0r inclined studs aff, m1 the frames A, and the slope-sided or ninder-ut holes in the slats if, substantially :is and ior the. pnrposa herniniefore set: forth.

2. The cnmbinzition nthe abutting-plate E, wedge i0, frame A, land sinty B, substantially as and fr the purpose hcreinbefore set fbi-nh.- r

v 3. The. combination ni' the 'curved draw-bolt U and nut. c', with the: trame A and sian B, as a, mmlicatziun nt' the wedge 1() und :shutting-pint@ E, as an@ for the purpose described.
