CHARLES TRAMILL AND JAMES H. TR AMILL, OF KANSAS CITY, MISSOURI.

PORTABLE sEoTIoNAL rLooR.

' Application filed October a, 1911. Serial no. 652,570.

To alt whom it may concern: Be it known that we,-CB:ARLEs TRAMILL and JAMES H.' TRAMILL, citizens of the United States, residing at Kansas City, in

the county of Jackson and State of Missouri,

have invented certain new and useful Improvement's in Portable Sectional Floors, of which the followin is a specification.

Our invention re ates to improvements in portable sectional floors. I

The object of our invention is to: provide a sectional floor whichimaybe-disposed in compact and convenient form for transpor tation and which may be quickly assembled in condition for. use and as quickly dismantled into knock down condition for shipment.

;A further object of our invention is to provide a structure which is cheaply made, which "is strong andrigid after being assembled in operative condition, and whichwhen assembled will floor surface.

The novel features of our invent-ion are hereinafter fully described and claimed.

While our invention is susceptible of being embodied in various forms, we have, in the accompanying drawings, illustrated the present a smooth even Figure 1 is a plan view, partly broken away showing sections of our improved floor connected in operative relation to each other, a section being shown detached from those which are connected witheach other. Fig. 2 is a vertical section on the line a-b of Fig. 1. Fig. 3 is a vertical section,'enlarged, on the line 0.d of Fig. 1. Fig. 4 is a vertical section, enlarged, on the line e-f of Fig. 1.

Similar characters of reference designate similar parts'in the different views. 7

The floor comprises a pluralitymf sections provided with means for being detachably connected together. Each section comprises a rectangular frame having two horizontal side joists. 1, two end joists 2 disposed against the ends of joists 1 to which they are rigidly secured by means of bolts 3 secured to the joists 1 and extending through the adjacent joists 2', and provlded with nuts 4 bearing against the outer sides of the endjoists 2.

Specification of Letters latent.

mediate joists 5 having-secured to them bolts 6 which extend through the adjacent ing against the outer sides of the joists 1. Extending between the joists 1 and parallel with and adjacent to one ofthe end joists 2 is an intermediate joist 8 having secured to it bolts 9 which extend through the adjacent joists 1 and are provided with nuts 10 which bear against the outer sides of joists '1. Secured also to thejoist 8 are bolts 11 which extend through the adjacent joist 2 and are Extending-- between the joists 1 are inter- "joists 1 and are provided wit-h nuts 7 bearprovided with nuts 12 which bear against said joist.

Secured to the floor frame are floor boards 13 which are preferably nailed to the intermediate joists 5 and 8 of the frameand have one set of ends resting upon the joist 2 which is adjacent to the joist 8, the other set of ends of the floor boards 13 being secured to and extending beyond the other end joist 2.

Preferably the floor boards; 13 have matching edges and ends, the ends being disposed in staggered relation to each other so as to I break joints when the section is connected to another section.

When the floor is to be assembled in operative condition, the frames may be mounted upon vertical pillars 14:, the sides of adjacent frames being disposed parallel with each other, and the adjacent ends of different frames being disposed-parallel with each other, as shown in Fig. 1. Whenthe frames are so arranged the projecting ends of the floor boards 13 of one frame are placed in matching engagement with the ends of the floor boards 13 which rest upon the end joist 2 connected to the joist 8 of the adjacent frame, the projecting ends of the floorboards also resting upon said end joist. Bolts 15 are, then inserted through the end joists 2 which are adjacent to each other,

said bolt-s having nuts 16 mounted thereon 13 of the, two sections in engagement with each other. I

The intermediate joists 8 are provided so astosupport the adjacent end joists 2 v against the strain placed upon them by the bolts 15. They also serve as joists to which r y bolts 17 which extend through adjacent other and placed in matchin ened, thereby forcin joists land have mounted on them nuts 18 {which bear against the inner sides of the joists 1. Before the nuts 18 are tightened intermediate floor boards. 19 are mounted upon the joists 1 which are adjacent to each engagement with the longitudinal edges 0 the adjacent floor boards 13. The nuts 18 are then tight the adjacent floor boards 13 tightly against the opposite edges of the intermediate floor board 19. It will be noted that the outer floor boards 13 of each section do not fully extend to the outer edges of the joists 1. This provides a bearing surface upon the upper side of each joist 1 for supporting an intermediate floor board 19. Neither do the boards 13 extend to the outer edge of the joist 2 which is next adjacent to the intermediate joist 8, thereby providing on the upper side of said joist 2 a surface for sup orting the pro'ected ends of the floor boar s 13 of the a jacent section. j Any number of sections may thus be assembled to form a floor. To disassemble the floor it is but necessary to remove the nuts 16and 18 after which the sections may be detached from each' other and from the intermediate floor boards 19. a

By securing the intermediate joists 5 and 8 to the side joists 1 by bolts 6 and 9 respectively, there is no danger of the side joists 1 being detached from the intermediate joists by the tension placed on the sidejoists by the clamping bolts 17. When the sections are detached, they may be stored in compact form.

We do not limit our invention to the structure shown and described as many modifications may be made within the scope of the appended claims, without departing from the spirit of our invention.

Having thus described our invention what we claim and desire to secure by Letters Pat ent is 1 In a portable sectional floor, two.floor sections spaced apart and comprising each a floor frame and floor boards secured to the frame, a detachable intermediate floor board resting upon said two frames and abutting at its longitudinal edges against adjacent floor boards of saidtwo sections, and means for detachably connecting to each other said two frames and for clamping the intermediate floor board against said adjacent floor boards. j

2Q Ina portable sectional floor, two floor sections-spaced apart and comprising each affioor frame having side joists and floor boards secured to the frame, two joists of said two frames being disposed parallel with each other, a detachable intermediate floor board resting upon said two-joists of said two frames and abutting at its longitudinal edges against adjacent floor boards of said two sections, and bolts extending through said two joists and having nuts fordetachably connecting together said two frames and for clamping the intermediate floor board against said adjacent floor boards.

3. In a portable sectional floor, two floor sections spaced apart and comprising each a floor frame and floor boards secured to the frame, a detachable intermediate floor board resting upon said two frames and. at its longitudinal edges having a matching engagement with adjacent floor boards of said two sections, and means for detachably connecting to each other said two frames and for retaining theintermediate floor board engaged with said adjacent floor boards.

4. Ina portable sectional floor, two floor sections spaced apart and comprising each a floor frame and floor boards secured to the frame, a detachable intermediate floor board resting'upon said frames and at its longitudinal edges havin a matching engagement with adjacent oor boards of the two sections, and a bolt having a nut and connecting said frames detachably with each other and retaining the intermediate floor board engaged with said adjacent floor boards. 1

5. In a portable sectional floor, two floor sections comprising each a floor frame and floor boards secured to the frame, the floor boardsof one section having one set of ends projecting and resting upon the frame of the other section and abutting against the ends of the floor boards of the other section, the frames. being spaced apart and means for detachably connecting to each other saidframes and for clamping together the floor, boards of the two sections.

6. Ina portable sectional floor, two floor sections spaced apart and comprising each a floor frame and floor boards secured to the frame one frame having an end joist an intermediate joist parallel to the end oist and bolts connecting said two joists, the

floor boards of the last named frame being secured to the intermediate joist and resting upon the end joist, the floor boards of the other section having one set of ends projectinge and resting upon said end joist and abutting against the adjacent ends of the floor boards of the opposite section, and means for detachably connecting to each other said frames and for clamping together the abutting ends of the floor boards of said sections.

In testimony whereof We have signed our CHARLES TRAMILL. I JAMES TRAMILL.
