BACK ron SEATS.
7 Specification of Letters Patent. Patented Jan. 25, 1921.
Application filed May 14, 1920. Serial No. 381,355.
. Seats; and I do hereby declare the following to be a full, clear, andexact description of the invention, such aswill enable others skilled in the art to. which it appertains to make and use the same.
This invention relates to seats, and particularly to those which are .plain boards such-as used in boats and canoes; and the object of the sameis to produce a back capable of'attachment to such a seat and adapted to be folded onto it when desired.
The invention consists more particularly in the peculiar means for clamping part of the'attachment to the seat and for hi-nging the back to said part and latching it when it stands upright; and while I- have described my invention herein as applied to the seat of a boat, it is obvious that it could be clamped to and used with other seats. 7
Details of construction are set forth below and shown in the drawings wherein:
Figure 1 is a side elevation partly in section showing this back as attached to the seat and in full lines as raised and in dotted lines as folded. Fig. 2 is a detail of the latch.
Fig. 3 is a plan view of the hinge and the upper end of the clamp.
Fig. 4 is a plan view. 7
The seat S herein shown is a plain board. The attachment includes .a cleat 1 also of wood recessed or c-hamfered on its upper side as at 2 sons to underlie the seat at its front end, and cut off on a slight bevel 3 at its rear end. The seat back is of any appropriate construction and preferably of light material such as wood, and its upright 4c is intended to pass down behind the rear end of the cleat 1, towhich it is hinged, and rest against the bevel 3 so that said upright will incline a little to the rear when the back is in usethe entire back being folded down over the seat when not in use, as seen in dotted lines in Fig. 1. The hardware includes a clamp for connecting the cleat to r may be said to be made up of two wooden elements and the necessary pieces of hardware, and it is quite obvious that it can be made and sold at a reasonable cost.
'The clamp comprises a' bolt whose shank 10. has a rib 11 extending along the rear side of its upper portion, its upper end being turned forward into a hook 12 whose billis widened and flattened to produce a lip 13 edge. This shank passes downvthrough the cleat 1 at the rear of its cut away portion 2, and its threaded end 14 projectsbelow the cleat;;and onto said end is strung a washer 15 and a hand nut 16 having afia-nge 17 at its upperend just beneath the washer.
v The hinge comprises an upper leaf 20 bolted at 21 to the -front of the upright 41,
The latch consists of a metal stri 30 which may be secured to the bottom of the cleat 1 by the same bolt 24: that holds the lower hinge leaf, and the front end of this strip is given a double elbow to form a dropped finger 31 which is preferably slightly dished on its front end as at 32. This finger underlies the flange 17 of the hand nut and prevents the latter from running ff the screw threads 16 while it does not interfere with the rotation of the nut. In other words, this structure produces a swivel mounting for the nut so that when it is turned to the left the entire clamping screw is pushed upward through the cleat and its lip 13 raised off the seat so that the device can be readily removed. The rear end of the latch is given a second double elbow producing a catch 33, beyond which is a thumb piece 34; and in the rear lower corner of the upright 4 is mounted a wear plate 35 which may be held in position by a screw 36. Thus when the back is raised until the lower end of its upright strikes the beveled end 3 of the cleat 1, the wear plate 35 passes over the thumb piece and the latch springs upward until its catch 33 en- I intended to overlie the seat S near its rear gages said plate. By this means the seat back is held upright until it is desired to fold it onto the seat, at which time it will be necessary to depress the thumb piece.
' When the attachment is thus applied, a passenger can Sit on the seat S and lean back in comfort. When it is desired to step over the seat or the use for the back has passed, the latch can be tripped and the back folded down as seen in dotted lines. At other times the clamp can be loosened and'the entire attachment' removed.
I have shown and described but a single upright and hinge. The construction of the seat back itself is not essential to .this in- Y vention, and a single uprightmight support an appropriate back rest. If there be two uprights there should be two hinges and the rear of the same, the clamp including'a nut vbelow the cleatprovided with a flange; of
the cleat in rear of said clamp, and a latch secured to the lower face ofthe cleat for a hinge connecting the front'face of an upright of the back with the upper facev of engaging the lower end of said upright when raised, the front end ofthe latch having a finger underlying said flange;
2. I11 a back for seats, the combination with the upright of the back proper, a cleat chamfered in'its upper forward corner to underlie the seat and a hinge whose leaves are attached -to,the upper face of the cleat and the front face of said upright; of a clamp including a shank passing through the cleat behind the seat and hooked forward, the bill of the hook being provided with a lip to overlie the seat, and a hand nut on the lower end of said shank.
In a back for seats, the combination with the upright of the back proper, a cleat chamfered in its" upper forward corner to underlie the seat, and a hinge whose leaves are attached to the upper face of the cleat and the front face of said upright; of a clamp including a shank passing through the cleat behind the seat and hooked forward, the shank having an'upright rib and the hinge leaf having a notch receiving said rib, a hand nut-screwed onto the projecting lowerend of the shank and having a flange,

In testimony whereof, I affix my signature, in the presence of two witnesses.
