BOAT OR CANOE CHAIR.

SPECIFICATION forming part of Letters Patent No. 441,534, dated November 25, 1890.

Application filed May 28, 1890.

To wZZ whom it may concern.-

Be it known that I, THOMAS H. OHUBB, of Post Mills, in the county of Orange and State of Vermont, have invented a new and useful Improvement in Boat or Canoe Chairs, of which the followingis a full, clear, and exact description.

My invention relates to a boat or canoe chair, and has for its object to provide achair consisting of a back, side arms, and clamps capable of being conveniently, expeditiously, and strongly attached to the seat of a canoe or boat, and which when so secured will form a perfect, complete, and comfortable chair.

A further object of the invention is to so construct the device that when not in use it may be folded up or made into a package so small as not to interfere in the least with the movements of the occupant or the occupants of the boat or canoe when paddling or rowing.

The invention. consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and

- pointed out in the claims.

Reference is to be had to the accompanying drawing, forming a part of this specification, in which is represented a perspective view of the device, illustrated as applied to the seat of a boat.

The frame of the device consists of two

vertical bars

10 and 11, which constitute the side bars of the back and stay-bars 12 and 13, one of said bars being pivoted at one of its extremities to the lower end of each of the

side bars

10 and 11 of the back, and to the opposite end of each of the stay-bars 12 and 13 a clamp 14 is pivotally secured, which clamps may be of any approved construction, being preferably made as shown in the drawing, in which they are illustrated as essentially U-shaped, and one member is provided with a setscrew.

In attaching the clamps to the stay-bars the stay-bars are ordinarily bifurcated, as illustrated at a, and between the arms of the bifurcated ends of said stay-bars the upper members of the clamps are pivoted.

The frame is virtually completed by hinging to the upper end of the back side bar 10, for instance, one extremity of a rod 15, the other end of which rod is adapted to rest in a Serial No. 353,428. (No model.)

fork 16, formed at the upper end of the opposite side bar 11.

In order to prevent the side bars of the back from inclining out but little beyond a right angle to the stay-bars 12 and 13, straps 17 are attached near the upper ends of the said side bars and near the outer ends of the stay-bars, the said straps being provided with buckles, whereby, if desired, the back of the chair may be more or less inclined. Instead of the straps, an equivalent therefor may be employed. The said'straps are attached at their ends to the sidebars and stay-bars, prefably by means of loops or rings 18, hinged or pivoted to the bars. I

In the stay-bars, near their pivotal connection with the side bars of the back, a key-hole slot 19 is formed, and between the side bars 10 and 11 a strip 20, of canvas, carpet, or other fabric or material, is stretched, adapted to afford a support against which the back of the person to be accommodated may rest. The strip of canvas 20 is substantially of a length corresponding to the length of the side bars and practically of a width corresponding to the width of the space intervening the said bars, and at the top and bottom of the strip 20

a hem

21 and 22 is respectively produced. Through the upper hem 2 1 the rod 15 is passed, and through the lower hem 22 a similar rod 23 is passed, the ends of which rod are also passed through transversely -aligning apertures 19 in the stay-bars. The lower rod is removable, and is provided near each extremity with an annular groove or channel to receive the walls of the slots 19, and the upper rod 15, at the end adapted to enter the fork 16, is also preferably provided with alike groove or channel.

In applying the device to a canoe or boat the

side bars

10 and 11 are folded out to a perpendicular position, or practically so, and the stay-bars 12 and 13 are made to rest upon the upper surface of the seat A. The clamps or cleats 14 are made to contact with the top and bottom of the said seat at one side, and are secured in place by means of set-screws forming a portion of the clamps.

plished by removing the lower rod 23 from contact with the frame and drawing the upper rod 15 out from the strip. The clamps or cleats are then disengaged from the seat and folded up against the

side bars

10 and 11. The two side bars and their attached staybars are then brought to a contact and the rod 15 folded down against the side face of the side bar to which it is pivoted. The

rods

15 and 23 may be then brought into engagement with the folded bars, and the entire set of bars be rolled in the canvas back 20.

I have used the word canvas as designating the material of which the strip constitutingthe back proper of the chair is composed, as canvas or duck is preferably employed; but I desire it to be distinctly understood that any desired material may be substituted for this purpose; also that the various portions enumerated as belonging to the frame may be made as light as possible consistent with strength, and that any contour maybe imparted thereto that fancy may dictate.

Having thus described my invention, 1

claim as new and desire to secure by Letters Patent-- 1. As an improved article of manufacture, a boat-chair comprising stay-bars provided with clamps at their forward ends, side bars hinged to the rear ends of the stay-bars, straps secured to the stay and side bars, and a detachable back held between the sidebars, substantially as described.

2. In a boat-chair, the combination, with stay-bars and side bars hinged thereto, of a bar secured in the rear ends of the stay-bars, a bar held in the upper ends of the side bars, and a piece of fabric secured to the said bars, substantially as described.

3. In a chair for boats, the combination, with side bars and stay-bars hinged together, of a rod detachably secured in the stay-bars, a rod hinged to one side bar and engaging the other side bar, and a piece of fabric provided with hems at the top and bot-tom to receive the said bars, substantially as and for the purpose set forth.

4.111 a chair of the characterdescribed, the combination with stay-bars having a clamping device pivoted at one end and provided with spaced apertures near the opposite end, and side bars pivotally attached to the apertured ends of the stay-bars, one of which side bars is provided with a forked upper end, of a strip of canvas or similar material provided with a hen: at each end, a rod passed through the upper hem and pivotally secured to one side bar and adapted to engage with the forked extremity of the opposite side bar, a detachable rod passed through the lower hem of the back strip and through the aligning apertures in the stay-bars, and an adjusting strap connecting the side bars and stay-bars, substantially as and for the purpose specified.
