FLOOR-CLAMP.

SPECIFICATION forming part of Letters Patent No. 781,312, dated January 31, 1905.

i Application filed June 8, 1904. Serial No. 211,712.

To all whom, it 11i/fry concer-ro: n

Be it known that we, ALANsoN R. SWETT and FRANK A. SIssoN, citizens of theUnited States, residing atAinsworth, in the county of Brown and State of Nebraska, have invented a new and useful Floor-Clamp, lof which the fol# lowing is a specification.

This invention relates to implements employed for forcibly pressing the contiguous edges of flooring, sheathing, and similarmaterial closely together in securing the samevto the substructure, and has for itsobject to produce a simply-constructed and efiicient device of this character vwhich may be employed upon the joist when the material'is to be attached directly to the joist or adapted with equal facility for operation upon the material resting upona level subfoundation. y

With these and other objects in view, which will appear as the nature of the invention is better understood, the same consists in certain novel features ofconstruction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which corresponding parts aredenoted by like designating characters, is illustrated the preferredy form of the embodiment of the invention capable of carrying the same into practical operation, it being understood that the invention is not necessarily limited thereto, as various changes in the shape, proportions, and general assemblage of the parts may be resorted to without departing from the principle of the invention or sacrificing any of its advantages,

and the right istherefore reserved of making all the changes and' modifications which fairly fall within the scope of the invention and the claims made therefor. i

In the drawings thus employed, Figure lis a longitudinal sectional elevation of a floorclamp constructed in accordance with the invention. Fig. 2 is a plan View of. the same.

- Fig. Sis a transverse section on the-line 3 3 of ,"headfl() oi' any suitablematerial, such as wood or metal or a combination of wood and metal, and adapted for resting upon the floor joist-(represented at 11) and provided with longitudinal guide-ribs 12 13 for engaging the n sides of the joist when the device is employed upon the iiooring (represented at 14) to berattached directly to the joist.

, 4 When'the device is employed upon iiooring attached-to a level subfoundation, as when the flooring is laid over sheathingthe ribs 12 13 will rest uponthe foundation.

' The bottom of the frame 1() and likewise theA ribs 12 13 are provided with inclined spurs 15 to enter the joist or subfoundation, according as to which -it rests upon, to cause'the frame to grip the part'upon which it rests and lprevent slipping'upon the same whe'nthe .plained f Mounted for movement longitudinally of I the frame 10 and near its lower side is a pressure-bar 16, projecting from one end of the frame and terminating in head 17, having a groove for engaging the tongue 18 on the` flooring 14. l

An operating-lever 19 is pivoted at 2O in the frame 10 and connected at its lower end by a link 21to the inner end of the bar 16, The bar 16is supported in position by a guideeplate 22, detachably connected to the frame 10."

Attached to the frame l0 is a curved notched segment 23, and the lever 19 is provided with means, Vsuch as a resilient pawl 24, for engaging the notches to maintain the lever at any p desired point.

i gage the tongue on the flooring 14, with the frame 1() resting upon the joist, and when reversed in position the groove in the head will engage the tongue on the flooring with the ribs resting upon the' sheathing or subfoundation level with the under surface of the fiooring.

By merely reversing the position of the head 17 the device may be adapted Jfor use upon the joist or upon a subfloor under the flooring to be clamped. The sam.eresult may be accomplished by forming the pressu re-bar with the head 17 set to one side of its center in the same manner as shown in Figs. 7 and 8 and reversing the pressure-bar bodily when the device is to be changed, as above noted; but the results would be the same and the manner of producing the desired results substantially the same.

Pivoted to the frame 10 at opposite sides and supported by hangers 30 31 are bars 26 27 for extension in advance of the frame, these bars fitting under the Hoor on opposite sides of the joist and serving to prevent displacement of the clamping-head and at the same time aiord a support for the clamp asa whole and prevent its movement from the approximately vertical operating position. When not required, the bars may be folded back to inoperative position.

When the device is employed for assisting in attaching sheathing or ceiling material, a bar 28 is mounted to swing upon the frame at one side and with a set-screw 29 in one end for engaging the studding or joist to enable the frame to be temporarily and adjustably connected in vertical or reversed position. By this simple arrangement it will be obvious that a strong leverage force may be applied against the edge of the flooring 14 to force it into close engagement with the next member and any .curves or irregularity in the same may be easily corrected.

Having thus described our invention, what we claim is- 1. In a floor-clamp, a pressure-bar, means for operating the same, and a detachable clamping-head having a grooved face engaging the tongued strips of flooring, said clamping-head being reversible to permit the adjustment ol the device to different horizontal planes.

2. A Hoor-clamp adjustable to diiferent horizontal planes, and having means for engaging a joist, and a detachable and reversible clamping-head adjustable to positions correspomlinj.;` to the operative position of the Hoor-clamp.

3. In a device of the class described, a frame having spaced longitudinal ribs for engaging the sides of the joist and with inclined spurs for engaging the joist and with inclined spurs in said ribs for engaging a level surface when the frame is placed thereon, a pressure-bar slidably disposed in said frame and having` a head for engaging the flooring and reversible in the frame, a lever pivoted in said frame and a link between said lever and pressure-bar.

4. In a device of the class described, a frame for resting on the joist and having inclined spurs for engaging the same, a pressure-bar slidably disposed in said frame adjacent to the joist and having a head Jfor engaging the iiooring to be clamped,a lever pivoted in said frame, and connected for operating said pressure-bar, and holding members movably connected to said frame for projection beneath the liooring.

5. In a device of the class described, a frame for resting on the joist and having inclined spurs for engaging the same, a pressure-bar slidably disposed in said frame adjacent to the joist and having a head for engaging the Hooring to be clamped, a lever pivoted in said frame, and connected to said pressure-bar. holding guide members movably connected to said frame for projection beneath the iiooring, and foldable rearwardly of the frame when not in use, and stops for limiting the movement in one direction.

In testimony that we claim the foregoing as our own wehave hereto aixcd our signatures in the presence of two witnesses.
