Application led May 5, 1906. Serial No. 315,386.

,I 15, having its normally free end recessed to l provide engaging portions 16, formed for en- ,l gagement with the teeth to lock the head Mansfield, in the county of Logan and State y against retrograde movement. of Ohio, have invented new and useful Iml In practice and in the operation of laying provements in Clamps, of which the following l the flooring if one of the boards be warped is a specification. f' it may be properly sprung into place by This invention relates to clamps designed clamping device, in applying To @ZZ whom t may concern.-

Be it known that I, GEORGE WILLIAMS, a States, residing at West l means of the which the fastening member is driven temporarily into the joist 12 and the head 7 arranged to bear on the flooring-strip 10, with the tongue 9 arranged in the groove 8. The lever 13 is then swung on the pivot 6, thereby rotating the head 7 for applying pressure to the board for swinging the latter into place, whereupon the locking member 15 is engaged with one of the teeth 5 for holding the clamping-head in clamping position while nailing the board to the j oist. It is to be particularly observed that owing to the head 7 being eccentrically pivoted the requisite amount of pressure may be brought to bear on the board for forcibly swinging the same into place and, furthermore, that by the provision of the teeth 5 on opposite sides of the arm 4 the device is adapted for use at either end of the and has for its objects to produce a comparatively simple inexpensive device of this character which may be readily applied for use, one whereby a board when sprung may be forcibly retained in proper position while being nailed, and one in which the clamping member may be quickly and securely locked in clamping position.

With these and other objects in view the invention comprises the novel features of construction and combination of parts more fully hereinafter described.

In the accompanying drawings, Figure 1 is a perspective view of a clamp embodying the invention and showing the same applied. Fig. 2 is a detail sectional view taken on a line centrally and longitudinally of the handle.

Referring to the drawings, 1 designates the board. body portion of the device, preferably in the Having thus described my invention, what form of a longitudinal member or bar bifur- I claim is 1. A clamp of the type described comprising a body portion, a head eccentrically pivoted thereto, an operating-lever pivotally connected with the body and engaged with and for moving the head, and means for lockingthe latter in clamping position.

2. A clamp of the type described comprising a body portion provided with teeth, an eccentric clamping-head pivotally connected with the body, an operating-lever pivoted to the body and iixedly engaged with the head for moving the latter, and a locking member connected with the head and adapted for engagement with the teeth to lock the parts in clamping position.

In testimony whereof I aflix in presence of two witnesses.

cated at its forward end to provide a slot 2 and a pair of spaced side portions or arms 3 4, of which the latter is notched or recessed along its side edges to form teeth 5, there being eccentrically pivoted at the forward end of the body 1 within the recess 2 and by means of a pintle 6, extended transversely through the arms 3 4, a disk-like clampinghead 7, provided with a peripheral groove 8, adapted to receive a tongue 9 of a piece of flooring 10, while extended through an opening at the rear end of the body 1 is an engaging member or screw 11, designed for fixing the clamp to a base-piece or joist 12.

Pivoted at its inner end on the pintle 6 is an operating arm or lever 13, having its outer end angularly bent or offset, as shown, said lever being attached at a point between its ends and on a line at right angles with the my signature body portion 1 to the head 7 by means of a Witnesses: fastening member or rivet 14, on which is P.
