DEVICE FOR THE RAPID LAYING AND AUTOMATIC TIGHTENING OF FLOORS.

Specification of Letters Patent.

Patented Oct. 24, 1905.

Application filed January 5, 1905. Serial No. 239,809.

To all whom it 71mg concern:

Be it known that I, ADoLPHn VAN DEN BULOKE, a citizen of the French Republic, and a resident of Lille, France, have invented a certain new and useful Device for the Rapid Laying and Automatic Tightening ofFloors and the Like, of which the following is a specification.

This invention has reference to an arrangement which permits of the rapid laying and automatic tightening of boarded floors, inlaid floors, or wood paneling and paving on metallie or other foundations.

The arrangement constituting the present invention has for its object, first, the rapid laying of boarded floors, inlaid floors, or wood paneling or paving on metallic foundations by means of spring fish-plates; second, the automatic tightening or loosening as they expand or contract of the different parts of which the flooring is composed. These two objects are obtained by means of a combination of special fish-plates and tightening-springs hereinafter described.

In the annexed drawings, given as an example, Figure 1 is a side elevation of one of the fish-plates. Fig. 2 is a front elevation. Fig. 3 represents the arrangement of a tightening-spring. Fig. 4: is a plan View of a portion of a boarded floor, showing diagrammatically in dotted lines the beams or girders C therefor. Fig. 5 shows in detail an angle of the boarded floor seen from below. Fig. 6 is a section on the line K L of Fig. 5. 7 is a plan view of a portion of an inlaid floor, the beams or girders 0 being represented by transverse lines. Fig. 8 shows in detail an angle of the inlaid floors seen from below. Fig. 9 is a cross-section in detail on the line M N of Fig. 8. Fig. 10 is a longitudinal section on the line 0 P of Fig. 8.

1. Fis/t-platcs.-The fish-plates are pieces of wood destined to hold the boards or wood panels, 860., of which boarded or inlaid floors are composed on the flanges of the iron beams U of the framework or bed in such a way as to prevent their rising up, while at the same time allowing of their movement eventually in the direction of the horizontal plane.

The plates A, Fig. 1, an example of which is given in the annexed drawings as a specimen only, can be of various forms and strengths, according to the application and form of the profiles of the iron framework or bed. They are attached underneath the boardpieces in case of need.

ed or inlaid floor by means of a screw B or by any other contrivanee in ordinary use.

2. TgMailing-springs E. --The tighteningsprings E (shown on the axis in action and relaxed in Fig. consist of some kind. of springs calculated in each case for the desired pressure. These springs-are maintained in a special device, which permits of their being compressed or relaxed, as the case may be. The arrangement consists, as shown in Fig. 3, of a simple square D or a double square D, called a blocl -square,fixed and a plate G, guided or otherwise, which can be brought nearer to or drawn farther away from the square at will by means of a screw F or by any other means.

Application of the systcm.-By way of example, in order to show clearly the working of the system an applicationto boardcdflooring or to an inlaidv floor may be shown as follows:

1. Application to a boarded floor. This application is shown in Figs. 4, 5, and 6. As

shown in Figs. 4C and 5, the flooring to be laid down is ordinary flooring. It consists of thin boards H H, &c., to be laid down on the iron girders O, and the tightening is effected in atransversaldirection. The block-squares D are placed at the ends of the iron girders C at the point where they are let in to the masonry and firmly lixed on the girders. The spring E is next placed in position and jammed up tight by means of the plate (:lr and the screw F. The laying of the flooring can then be proceeded with, the boards being previously provided with fish-plates A, suitably arranged. To facilitate the laying, the fish-plates should be placed parallel to the girders C, so that a board put into place and a quarter-turn given to the fish-plates the side all, by which it is held, should dovetail into the upper flange or part of the girder G, thus fixing the board. The same method should be adopted with the other boards until aboard H or key is placed in position. The same operation can be repeated in starting from the opposite wall. Then after a n'eliminary tightening of the other boards the board H can be dropped into its place. This latter being maintained in the grooves of the adjacent boards will not carry fish-plates, which will allow of the floor being easily taken to This being done, the

only thing left to do is to proceed to the tightening up of the boards, which is accom- 2. Application to cm inlaz'dfiomu-This ap-- plication is represented in Figs. 7, 8, 9, and 10. In the case of a wood-paneled floor the tightening should be made in the longitudinal and transverse direction. To further allow of this tightening, the squares D should be fixed to the girder C alongside the Walls and their distance apart maintained by tie-rods R, as shown in detail in Fig. 10. The springs E previously placed in position and tightly compressed, as indicated in the case of the boarded floor, the laying of the panels can then he proceeded with. The panels I, pla'ced alongside the transverse walls, where they are kept in position by a plinth alone, will not have fish-plates. The second row will then be placed and each panel J held up by asingle fish-plate A, as shown in Fig. 8. The panels being firmly held together among themselves tongued and grooved, the fish-plates will hold at the same time the four angles of the panels and will prevent any upheaval. The other rows will then be placed in the same way. The panels thus placed, the springs E will be relaxed, as in the case of the boarded floor, in order to obtain the permanent tightening in the two directions, allowing of the expansion and contraction of the component parts with a view to obtaining a perfect fastening without the possibility of coming undone. The paving on flap-stones is placed in the same manner; but the joints are filled up with putty before tightening. Y

Having now fully described my said invention, what I claim, and desire to secure by Letters Patent, is

An arrangement allowing of the rapid laying of boarded floors, inlaid floors, panels &c., on metal beds or framework and the tightening and relaxing of the same automatically according to the expansion or contraction of the various component parts of the boarded floors, inlaid floors &c. comprising the combination of fish-plates destined to hold the boards or panels, of which the floors are composed, on the flanges of the iron girders of the framework or bed in such a way as to prevent their upheaval while at the same time permitting of their movement in the horizontal plane, and of tightening-springs inserted each one between a fixed square and a plate that can be brought nearer to or drawn farther away from the square at will by means of a screw which allows of these springs being compressed or relaxed as the case may be.

In testimony whereof I have hereunto set my hand in presence of two witnesses.
