PORTABLE KNOCKDOWN rLooR.

To all whom it may concern:

Be it known that I, ARTHUR BVELDRED, a citizen of the United States, residing at Paola, in the county of Miami, and State of Kansas, have invented a new and useful Portable Knockdown Floor, of which the following is a specification.

The present invention appertains to a portable knockdown floor, and aims to pro-.,

It is the object of the invention to provide a portable knockdown floor which may be' readily and effectively set up or assembled to provide a firm or solid floor or base, which may be used as a skating rink floor, dancing hall floor, and the like, and which floor may be knocked down so that the parts thereof may be readily transported or stored away within small encompass.

The present floor constructionis adapted especially'for use in amusement parks, fairs, and the like,-to enable the structure to be knocked down and shipped readily from place to place, and to enable the parts to be readily assembled in a thoroughly practical and eflicient manner to provide a firm fioor.

As a more specific object, the invention contemplates the provision in a structure of the nature indicated, of unique means for securing the several parts together, whereby they will be held assembled in a most substantial' manner, to resist the strains to which the floor is subjected in use, and without the liability of any of the parts becoming displaced or loosened. It is also within the scope of the'invention to provide a portable knockdown floor having the features above noted, and which is comparatively simple and inexpensive in construction, as well as being convenient, serviceable and practical in its use.

With the foregoing and other objects in view which will appear as the description proceeds, the lnvention resides in thecombination and arrangement of parts and in the details of construction hereinafter .de

scribed and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can bemade Patented Nov. 16,1915.

Application filed. March 19, 1915. Serial No. 15,552.

within the scope of what is claimed without departing from the spirit of the invention.

The invention-is illustrated in the accompanying drawings, wherein v Figure 1 is a plan view of the floor structure, portions being broken away. Fig. 2 is an enlarged transverse section taken on the line 22 of Fig. 1, portions being broken away. Fig. 8 is an enlarged transverse section taken on the line 33 of Fig. 1. Figs. 4: and 5 are sectional details taken on the lines 44 and 55, respectively, of Fig. 2.

In carrying out the invention, there is provided a longitudinal series of transverse joists l and 2, which'are disposed in alternate arrangement, and the'joists of each set arearranged inpairs; The pairs of joists land 2 are spaced apart at suitable distances, and are parallel with one another. The joists extend to the sides of the floor structure, and are divided intermediate or midway between their ends, to provide the side sections 3. The outer or remote ends of the sections 3 are seated upon longitudinal side sills 4, and the inner or adjacent ends of the jois sections 3 are seated upon a central or intermediate longitudinal sill 5. Other longitudinal sills 6' may be disposed between the sills 4 and 5 for supporting the intermediate portions of the sections 3. These

sills

4L, 5 and 6 may be placed upon the ground or other base, for supporting the floor, and the sills may be constructed in sections so that the sill sections can be handled readily.- A tenon 7 is secured between the inner ends of the joist members of one section 3 of each pair of joists,.and is adapted to project between the inner ends of the joist members of the corresponding section 3, for holding the joist sections 3 in alinement. It is evident that when the sections 3 of each joist are assembled, the tenon 7 of one joist section is slipped or inserted into the inner end of the corresponding section 3, which will hold the joist arrangement. The ends of the floor sections 8 abut over and rest upon the joists 2, and the ends of the sections 9 abut over and rest upon the joists 1. These floor sections 8 and 9 may be constructed of boards secured together in any suitable manner.

The central or intermediate row'of floor sections 8 which lie above or rest upon the adjacent or meeting ends of the joist sections 3, are provided with lower longitudinal cleats 10 which are seated within upper notches 11 provided in the jointsections adjacent the inner or meeting ends of the joist sections, whereby the cleats 10 of the sections 8 in engaging or seating within the notchesll will assist in holdingthe joist sections assembled, to prevent their separation until the central or intermediate floor sections 8 are raised or moved.

Mounted or seated upon the outer or remote end portions of the joist sections 3, are upstanding supports 12, which are provided with depending strips or portions 13 over lapping the joist sections 3, to hold the supports 12 slidably upon the joist sections, and to prevent the supports 12*from shifting longitudinally relative to the entire struc ture. Secured in any suitable manner upon the supports 12'are seat boards or sections 14: and foot rests or aisles boards or sections 15. The seat boards or sections 14 are disposed at a higher level than the boards or sections 15, and the boards or sections 15 are disposed inwardly relative to the seat boards or sections 14. The boards'or sections 14 provide seats for the spectators or onlookers, and the boards or sections 15 provide foot rests for the spectators, and also provide aisles extending longitudinally of the structure between the longitudinal seats and the floor proper provided by the sections 8 and 9.

Upstanding railing posts '16 have their. lower ends inserted between the joist members of the sections 3 between the supports 12 and the remote or side floor sections 8, and cables or other members 17 may be stretched between the posts 16 at the opposite sides of the floor proper to divide off the spectators from the persons occupying the floor proper. The boards or sections 15 are raised above the floor proper, and kick boards 18 are set on edge upon the joist sections 3 between the remote or outer floor sections 8 and the posts 16, and will serve to define the sides of the floor proper. The kick boards 18 extend longitudinally of the structure, as will be apparent.

Means are provided for securely fastening the, several parts upon the joists, and'for holding the joist sections together, the said means belng assoclated with the joists 1 and 2. The securlng or fastening means of each 7 pair of joists 1 embodies a pair of cables 19 assembled with the respective joist sections 3 and arranged between theipair of joists.

These cables 19 are passed over pulleys or other guides 20 carried by the lower surfaces of the floor sections 8, and the cables 19 are passed under pulleys or guides 21 carried between the joist members of the sections 3 between the fioor sections 8. The central or intermediate floor section 8 is provided with pulleys or guides 22 at the opposite sides of the adjacent or meeting ends of the joist sections, and over which the cables 19 are passed. The inner or adjacent end portions of the cables 19 arecrossed and extend to the opposite joist sections. The inner end of each cable is provided with a hook 23 engaged toone of a series of rods 24: secured between the joist members of the opposite section 3. The hooks 23 beingen- .gageable with the series of rods 21, provides adjustable means tor engaging the inner'ends of the cables 19 to the opposite joist sections. the cables 19 are passed under pulleys or The outer or remote end portions of guides 25 carried between the joist members of the sections 3 below the supports 12 or adjacent the outer or remote ends of the joist sections, and the outer or remote ends of the cables 19 are attached to rods 26 which are slidable through suitable guides or bearings 27 carried by the respective supports 12. Nuts 28 are threaded upon the rods 26 and bear against the bearings27.

The securing or attaching means of each pair of joists 2 is similar to the securing means of the joists 1, but there are slight differences between the two sets of securing means. Thus, the securing means of each pair of joists 2 embodies a pair of cables 29 associated with the respective joist sections 3, and passed over pulleys 0r guides 30 carried by the lower surfaces of the floor sections 9 and under pulleys or guides 31 carried between the joist members of the respective sections 3 between the floor sections 9. The inner end portions of the cables 29 are crossed and extended to the opposite joist sections 3 and the inner ends ofthe cables 29 are provided with hooks 32 engageable' with a series of rods or members33 carried 7 by the respective joist sections 3, the same as with the securing means of the joists 1. The remote or outer end port-ions of the cables 29 are passed under pulleys or guides 31 carried by the respective joist sections 3 sections 8 and 9, supports 12, railing posts 16' and kick boards 18 are then placed'properly upon the joists, and'at the same'time, the cables 19. and 29 are assembled with the partsin the proper manner. The hooks 23 and 32 will be engageable with the series of rods or attaching elements 24 to provide for a quick adjustment, as will beapparent, and

1 after the parts have been assembledas above spective cables being rendered taut, will pull,

the joist sections 3 tightly into abutment with one another, and furthermore the supports 12 will be moved inwardly. This will.

clamp the floor sections 8 and 9 together for providing a smooth floor surface, and the railing posts 16 and kick boards 18 will also be clamped between the supports 12 and remote or side fioor sectionsS to hold the said posts and kick boards in position. The cables being passed over the pulleys or guides of the joists and floor sections in the manner above indicated, will be disposed in a zig-zag arrangement, and when the cables are tightened, they will tend to straighten out, so as to securely clamp the floor sections upon the joists. As a result of the peculiar means of securing or attaching the various parts together, the parts will be held firmly in place, and will not be liable to become displaced 0r loosened even though the structure is subjected to considerable weight or strains. means are employed for attaching the parts upon the joists, and the securing means of the present device are comparatively simple, and are most expedient and eiiicient in use.

It will be understood that the structure may be made in various sizes and attention is also directed to the fact that the cables being tightened will clamp the supports 12 upon the joists as well as moving the sup ports 12 inwardly to clamp the floor sections, railing posts and kick boards in place. It is thus impossible for any of the parts upon the joists to be raised accidentally, and the cables serve to both hold the parts upon the joists, and to clamp them together, and furthermore, to clamp the joist sections together. hen the cables are loosened or detached, the parts of the structure may be readily separated, so that the structure may be transported readily, or stored within a small encompass.

From the foregoing, taken in connection with the drawings, it is believed that the advantages, attributes and capabilities of the present invention will be obvious to those skilled in the art, without further comment being necessary. The present structure pro- No bolts or similar securing vides a desirable and eflicient portable knockdown floor for use in skating rinks, dance halls, and the like.

Particular attention is directed to the fact that the pulleys or guide members of the floor sections are carried by the intermediate portions of the floor sections, whereby the intermediate portions of the respective floor sections will be drawn downwardly tightly upon the joists, and whereby. the end portions of the floor sections of the alternate rows will be clamped between the intermediate portions of the floor sections of the adjacent rows, in order that the ends of the floor sections will be properly clamped in place. It is also to be noted that the cables 19 being attached at their inner ends to the opposite joist sections, will prevent the floor sections and seat supports from shifting, as

and means connecting the floor sections with- .one another and with the joist and so arranged, that a singleadjustment is transmitted, to simultaneously draw the floor sections together and down tightly upon the joist.
