FLOOR.

Specification of Letters Patent.

Patented July 16, 1918.

Original application filed July 28, 1916, Serial No. 111,928. Divided and this application filed September 18, 1917. Serial No. 191,990.

To all whom it may concern:

Be it known that I, NORMAN JOHN MAC- DONALD, of the city of .Winnipeg, in the Province of Manitoba, Canada, have invented certain new and useful Improvements in Floors, of which the following is the specification.

The invention relates to improvements in fioorsand the object of the invention, which is a division from application Number 111,928, filed July 28, 1916, is to provide an inexpensive easily constructed floor which can be quickly set up. whenrequired for use and as easily taken down for shipping or storage purposes and while providing a floor of this type, construct it so that it will be tight fitting, whichfeature is an important one as will readily be appreciated.

A still further object of the invention is to constructafloor which requires no nailin or similar permanent fastenings when being set up, and while avoiding these, to supply a rigid structure serviceable as a flooring. V v c I I.

With the above objects in-view the invention consists essentially in a substantially rectangular take-down frame, a floor formed from floorboards insertible within the frame, filling strips associated with the floor boards and floor joists or sleepers passing lengthwise of the frame and beneath the floor boardsthe parts being arranged and constructed as hereinafter more particularly described and later pointed out in the appended claims, reference being had to the accompanying drawing in which Figure 1 represents a perspective view of a floor constructed in accordance with my invention, parts of-the floor being broken away to expose construction. m

Fig. 2 represents an enlarged detailed perspective View of one of the corner joints of t e frame, the said joint being pulled apart.

Fig. 3 represents a vertical sectional view through the floor at the end. I

I have found hat there is considerable demand for a collapsible ior'knockdown floor which can be utilized for camping purposes seasonafter season or as" the floor of a sectional house and in vordertdsupply-such a demand I have invented the present floor which can be manufactured cheaply, can be set up or taken down quickly and is of su he naturezthat'it-canbe shippe r t red very conveniently. v Refe ees sew m the stems i Wi h like characters of reference indicate corresponding parts in the several figures.

1 represents a substantially rectangular floor frame formed from similar side members 2 and 8 and similar end members 4 and 5. The said side and end members are actually made from a body or main strip 6, to the top and bottom sides of which I permanently, fasten, suchas by nailing, equal width top and bottom strips 7 and 8, the outer edges of the latter strips lying flush with the outer edge of the main strip while the inner edges of the top and bottom strips overhang the inner edge of the body strips and form with it a channel 9.

It will here be observed that the main strips of the end members 4: and 5 are somewhat longer than the attached top and bottom strips so that they project in extensions 6 and 6 which are adapted to be received between the extending ends 7 and 8 of the top and bottom strips of the side members of the frame.

From the above construction it will be obvious that the frame members can be quickly put together by fitting the extending ends 6 and 6 of the end members between the extensions 7 and 8 of the side members and holding them together by inserting through the openings 10, corner bolts 11.

In this connection it is to be noticed that once the corner bolts are inserted the frame is more or less a rigid one as the manner in which the corners go together provides a tight fittingcorner once the bolt is inserted.

The end members of the frame are arranged to lie on floor joists or sleepers 12, which joists have their ends rabbeted away as indicated at 12 to receive the lower cross strips of the end'members 4: and 5 in such a manner that their upper faces Will lie flush with the upper faces of the said cross strips. The joists are held to the end members by inserting bolts 13 through the joists and the end members, registering-openings being provided. j

Within the frame I insert floor boards 14 which floor boards passina direction at right angles to the joists on which they lie. The floor boards are all of an equal length and are-so, adapted that when in position their. ends lie in the" channels of the side members 2 and 3. In connection with the insertion of these floor boards within the I may mention that I have found it fr m he h h a sale 019 de r le to e ter by cutting away a portion of the body strip 3 6. By providing this opening it will be seen that I am-able toset the frame noon the joists and then put the floor boards in porsition -by threading them, so to speak,

through the opening 15 until the cn'dsthereof take theirpositions in the channels and then sliding the boards one after the other in oppositedirections to the ends of the frame.

In the drawing I have shown the last board to beinserted as only partially in and I- have also-shown the inner or advanced end of this board- With its sides slightly cutaway to provide a more or less Wedge shaped or driving end- 14*. This arrangement allows ofthe easy entering of the last floor board to be laid and, also permits of the effective tightening up of the floor, as after the pointed end of the lastfioor board has beeirinserted through the opening" it can be driven in by} a mallet to close the cracks in the floor.

After the floor boards have been placed in positionfilling strips '16 are-inserted Within "thechannels'abovethe floor boards and beily apparent that this floor can be ;very

quickly set up and as easily taken apart and that it requires no specialtools to lay it and further that it is a particularlyneatflight, convenient, and durable floor for camping or other similar purposes.

VV hi1e lhaveideseribed one, and possibly the most preferable, manner ofsettingflup the floorstill it 'will be understoodthat this is not the only Way it can be set up in a *quick and eflicient manner as 'obviously'the i --frame could be set up. With one of the side '-members removed and the-floor boards could be placed in position on the attached joists and 'then'the removed side piece could be 'fiirallyplaced in position onthe ends of the boards.
