The invention relates to' improvements in.

preciable movement in an endwise direction,A

so that there is no vdanger of the seat bump ing upon the ends of the supporting frame or catching upon the seat Suspenders.

With the foregoing in' View, the inventiony resides in the novel subject matter herein-` after 'described and claimed, description being accomplished by referenceto the acl-- -companying drawing.

Fig. 1 is a front elevation partly brokenl away and in section. y y y Fig. 2 is a top plan view. y

Fig. 3 is a view similar to l but showing a different form of construction.

A mainstationary frame is shown em-' bodying two"spaced vertical end frames 5 and a longitudinal barb connecting the lower portions of said frames and suitably braced thereto asy at 7. Above the bar 6 is` a seat frame 8`su'spended from the upper portions of the frames 5 by chains, rods or other desired means' 9.

' In Figs. 1 and 2, two contrivances C which I term equalizers, are shown connecting the frame-8 with the bar 6 to prevent endwise A movement of the former. Any desired numl ber of these contrivances may be used and as the two shown vare of identical construction1 only' one will be described in detail.'

The numeral 10 denotes a substantially 40 vertical link which is pivotally hungpvfrom either the front or rear portion of the seat frame 8, and twin links 11 are disposed substantially in horizontal positions, are-shown. -These links 11 converge to a common point and at this point are pivoted at 12; to .the lower end of the linklO. The widely spaced ends of the twin links 11 are pivoted at 13 to the bar. Preferably-this bar is provided with two rigid Lshaped lbrackets-111 engaging the pivots 13. vSimilarbrackets lare.4

suspen ers 9 or the end frames 5. ously, all front-to-rear and all vertical moveemployed at the upper end of the link 1() and \contacting with opposite sides of the latter,

said link 10 being connected with these brackets by a rivet or other pivot 16.

All lof the link pivots 12-13-16 have their. vaxes disposed longitudinally of the frame 8 and bar 6 so that they will not interfere with proper swinging of the'seat. The links 10-11 arel substantially rigid in a v,direction at right angles to the front-to-rear vline of movement ofthe seat and 'hence they prevent this seat from moving endwise with any discomfort to the occupant or with danger of art'sfof the seat striking against the Obvii ments of'v the seat are permitted by the. mounting of the links so that the latter may follow all movements of the seat except end--y wise movement thereof and will prevent the latter. f Y Inl Fig. 3, `allconstruction is the same as that above drscrilmd with the exceptionthat eachl equalizer-.0 embodies two downwardly converging verticale links 10u instead of one vertical link such as 10.` The upper ends of these links 10a are pivoted at 16a to brackets 15il secured to the 'seat frame 8 and the lower ends of said links 10a are pivoted at 12a to the closely spaced front ends of the links 11.. This provides a construction which is even more stable against endwise shifting.`

' Excellent results are obtainable from the details disclosed and they are therefore pre` ferably followed. However, within the scope of the invention as claimed, variations may be made. 1

Iclaim 1. In/ a glider, a stationary frame mem-a rvbeing substantially rigid in ydirections at righ'tiangles to saidfront-to-rear line to:

frames and a central 4horizontal bar conneetl ing the lower portions thereof, Suspenders` hung Jfrom saidV end frames and@J seat frame prevent vmovement of the seat member transversely of this line.

In a glider,`a stationary 'frame member, afseatmember movable with respect thereto, twin links pvoted at spaced pointsto said frame member and converging to a common point, and twin. links pivoted to said y Seat member. at spacedpoint's and also converging to a common point, the two sets of twin links being pivoted together at sai-d common point.L

3.; A glider comprising two stationary end supported by' said Suspenders, twin links downwardly converging. to a common point from said seat frame and pivoted at their upper ends to the latter, and additional substantially horizontal twin links converging to said common point and pivoted to said horizontal bar, the two sets of twin links. l

being pivoted to eachother at said common point. f

In testimony whereof I have' yhereunto ajfixedmy signature.

DUANE M. LILLIBRIDGE.
