FLOORING-CLAMP.

SPECIFICATION forming part of Letters Patent No. 654,365, dated July 24, 1900.

Application filed July 29, 1899. Serial No. 725,513. (No model.)

To all whom, it may concern:

Be it known that we, ARTHUR LUOIUS SToWELL and ARTHUR HERMAN RoUNDs, of Gays Mills, in the county of Crawford and State of Wisconsin, have invented a new and Improved Flooring-Clamp, of which the following is a full, clear, and exact description.

One object of our invention is to provide a simple, durable, and economic device for clamping flooring together when laying the same and for drawing down drop-siding, ship-lapped sealing, or any matched or un matched lumber where it is necessary that a tight joint should be made, and whereby She material may be laid upon joists or studing.

Another object of the invention is to construct a flooring-clamp capable of use upon lumber of different thickness and which may be manipulated with one hand.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of the improved device, parts thereof being broken away. Fig. 2 is a perspective view of the device, illustrating it as applied to studding and sealing to be secured to the studding. Fig. 3 is a section taken practically on the line 3 3 of Fig. 1, and Fig. l is a section taken substantially on the line 4 4 of Fig. 1, but looking in an opposite direction.

A plate A is employed adapted to engage with the edges of the boards 0, that are to be secured either to studding D, as shown in Fig. 2, joists, or their equivalents. This plate A may be of any desired size and is provided near one end upon its upper face with a bear ing 10 of any suitable character, and near its opposite end, also uponits upper face, the said plateis provided with transversely-alluing jaws 11.

A body-arm B is used in connection with the plate. This arm comprises a sleeve 12,

having a horizontal recess 12 in its outer end, a member 13, and a connecting member 14, the connecting member being at an angle to both the sleeve 12 and themember 13. The member 13, which may be termed the biting member, is provided with a polygonal or square section 15. This section is located between the jaws 11, and one face of the section rests upon the upper surface of the plate. The'jaws 11 firmly clamp the biting member 13 adjacent'to each end of the polygonal section 15, and at the outer end of the biting me1nber l3 a spur-l6 is secured or integrally formed, and this spur is curved inwardly and upwardly and extends upward at an angle to the upper face of the plate A When the device is horizontally located. Thus it will be observed that the body-arm B is rigidly attached to the plate A.

A clampingbar 17 is mounted to turn loosely in the bearing 10, and said bar 17 is carried loosely through the sleeve 12 of the body-arm and is attached to a handle 18. A lug 17 is formed upon said clamping-bar, and this lug is adapted to turn in the recess 12 of the sleeve of the body-arm B, as shown in Figs. 1 and 4.. A dog 19 is located at the outer end of the clamping-bar 17, opposite the spur 16, and said dog is provided with an inner convexed surface and usually with an outer concaved surface. The dog is further provided in its inner convexed surface with series of teeth 20, as shownin Figs. 2 and 3.

It will be observed that the bearings 10 and 11 are made in two sections, so that the parts to be received may be placed between the sections and the sections shaped over the parts.

In operation when the device is to be used in connection with studding D the plate A is made to rest upon the upper edge of the board 0 to be laid, or that edge of the board which is to receive a fellow board, and the spur 16 is made to enter one side of the stud= ding. The clamping-bar 17 is then turned to bring the teeth of the dog 19 in engagement with the opposite side of the studding, and by further turning the bar 17 upon the dog 19 as a pivot-point the board Owill be forced against the board previously laid and. may be held in close engagement with saidboard until the board to which the device is applied can be nailed properly to the studding.

The device is exceedingly simple, durable,

and economic, and, as stated, may be readily manipulated by one hand.

Having thus described our invention, we claim as new and desire to secure by Letters Patent-- l. A clamp, comprising a compressingplate, an angular armattached to said compressing-plate, one member of which angular arm is tubular, a spur attached to one member of said angular arm, a bar held to turn in the tubular portion of the angular arm, and a dog carried by said bar, the dog being opposite said spur and provided with teeth in the surface that faces the said spur, for the purpose described.

2. A compressing-plate, an angular bodyarm secured rigidly to said compressing-plate, the inner member of said angular body-arm being tubular and the outer member provided with an inwardly and upwardly curved spur, a bar held to turn upon the co mpressing-plate and in the tubular portion of the body-arm, and a curved dog secured to the outer end of the said bar, the convexed face of which dog faces said spur and is toothed, for the purpose described.

3. A compressing-plate, an angular bodyarrn secured rigidly to said compressing-plate, the inner member of said angular body-arm being tubular and the outer member provided with an inwardly and upwardly curved spur, a bar held to turn upon the compressing-plate and in the tubular portion of the body-arm, a curved dog secured to the outer end of the said bar, the convexed face of which dog faces said spur, a handle for the said bar, and means for limiting the movement of the said bar, for the purpose set forth.

4:. In a flooring-clamp, a compressing member, a stationary clamping member comprising an arm extending at right angles beyond one side of the compressing member, terminating in a spur, an intermediate section ex tending along the opposite side of the compressing member and a sleeve at an angle to the intermediate section, a bar held to turn in the sleeve-section of the clamping member, and a dog fastened to said bar, the working surface whereof faces the spur, as described.
