SPECIFICATION forming part of Letters Patent No. 3,523,415I dated Angus-51:4, 1885.

Application filed May 7, 1885. (No model.)

To all whom, it may concern/.-

Beit known that I, JOHN F. GRnssLE, of Hamilton, Butler county, Ohio, have invented certain new and useful Improvements in Tree- Seats, of which the 'following is a specification.

This invention pertains to a seat for use in combination with the trees of a lawn, park, or picnic ground.

The invention will be readily understood from the following` description, taken in connection with the Iaceoinpanying drawings, in which- Figure l is a plan of a tree-seat embodying iny improvement, a number of the wooden sectors forming the seat proper being omitted, so that the inetal work below may be exposed; Fig. 2, a half-vertical section and halfclevation ofthe same, and Fig. 8a bottoni view of one oi the seat-boards. Y

In the drawings, A indicates a ila-t ring, formed of cast-iron, in segments bolted or otherwise secured together; B, a joint of separation where two contiguous segments are united 5 C', a downwardlyprojecting iiange at the inner margin of the ring; D, an ornamental skirting cast upon the periphery of the ring; E, radial slots through the metal of the ring; F, lugs projecting upward from the face oi' the ring and disposed at the periphery of the ring in line with the slots; G, holes through the metal of the ring, serving to lighten the casting; H, sector-shaped pieces of wood forming a ilat circular series disposed upon the top ot' the metal ring and forming the Vseat proper; J, bolts engaging through the seatboards and the slots of the ring, K, a longitudinal groove in the under side oi' each seat board, adapted to engage the lugs F; L, castV legs secured to the periphery of the ring-cast ing, as by bolting, riveting, or by tenoning after the manner of stovelegs; M, leg-screws having foot-pieces cast or otherwise secured to their lower ends and engaging upward within the legs; N, nuts for the screws M, set in transverse mortises cast in the legs; O, the central aperture in the seat proper for the reception of the tree, and P the tree-receiving central aperture oi' the ring-casting.

The seat is to be applied as follows: The ring is opened at two of its joints, and then reconnected around the tree. The seat-boards are then applied and adjusted inwardly to iit the tree, and the bolts screwed up with sufricient force to hold the seat-boards to the cast- 5- ing without interfering with the outward radial movement of the boards as the tree increases in size. The legscrews are then adjusted to bring the seat to the proper height, each leg-screw being adjusted with reference to the inequality of the ground at the foot of the tree. As the tree grows the seat-boards are forced outward, and the seat is kept properlyleveled by occasional adjustment of the leg-screws to compensate for irregularities in ground-surface produced by the swelling growth of the roots of the tree. The seatboards are guided in their radial travel by the bolts engaging the slot-s and by the lugs engaging the groove. Then the growth of the tree 7o has expanded the seat as far as is thought desirable, the inner ends of the seat-boards may be sawed off and the sectors again set inward;

or new seat-boards, of the desired length, may

be applied, and the older and longer boards may be applied at a smaller tree.

I claim as my inventionl. In a tree-seat, the combination. with a ring and its supporting-legs, of a circular series oi' sector-shaped seat-boards secured to 83 said ring, as by means of bolts engaging in radial slots, and adapted to move radially outward as the tree expands in growth, substantially as set forth.

.2. In a tree-seat, the combination of a radially-slotted ring-piece, a circular series of sector-shaped seat-boards secured thereto and vertical extensible legs secured to the iinopiece, substantially as and for the purpose st forth.

3. In a tree-seat, the combination of rin@ A having slots E and lugs l?, supporting-lega@ sei' cured to the same, and sector-shaped seatboards H, provided with guide-grooves K and secured to the ring by bolts J, substan gr tially as and for the purpose set forth.

4. In a treeseat, the combination of radially-slotted ring A, sector-shaped seat-boards H, secured thereto, legs L, secured to the ring and footed screws M, engaging the legs sub 1c stantially as and for the purpose set forth.
