METER-CLAMP.

Application filed March 7, 1917.

citizen of the l'nitcd Stat s residing at Dal: Park, in the county of Cool: and State of lllinois, have invented new and useful Improvements in Miterllainps' of which the following is a specification.

This invention roniprcheniils improvements in clamps and relates more particuarl to a miter clamp for use in securing are frame sections and analogous sec- 1 gluing or nailing the same.

ol the objects oil the invention t.

a very simple and practical miter clamp whici will engage the n'iitered ends or two members and hold them in such fashion that the will not split when nailed to ctheri Another object of the invention is to provide a niiterclainp having a. frame or base plate upon which is} slidahly mounted a clamping plate, the base plate being provided with flanges haying notches therein to permit nailing and the clamping place being formed in sections between which are secured holding; spurs.

The invention also aims to generally improve clamps of this nature to render hem more nractical, useful and commercially desirahle.

With these and'other objects in View as will become more apparent as the description proceeds, the invention consists in certain novel features of construction. combina- 2 is a side elevation of the clamp.

The tor-ward edges of these plates are convergent toward the longitudinal center of the frame screws connect the plates 7 and 8 and the ruler plate .10.

memlier as will be readily understood.

From the foregoing description taken in connection with the accompanying drawings,

'it will be seen that l. have provided a very i wish to be limited to this construction, but

may make such changes as will fall within the :scope and spirit of the invention as claimed.

lVhat I claim is:--

1. A miter clamp comprising a frame plate, flanges on said frame plate forming a closed angle, a clamping member slidable on theframe plate, said clamping member being formed of two superposed plates, spursremovably secured between said plates and projecting beyond the forward edges thereof, each of the plates being formed with grooves. and the grooves of one plate cooperating with the grooves of the other plate to form sockets for the spurs, and means for forcing the clamping member to ward the flanges.

2.."1 miter clamp comprising a frame plate, flanges mounted on said plate and converging toward the medial line thereot, said flanges being disposed at right angles to each other and meeting at their opposed ends to form a closed angle. the flanges being formed with upwardly opening nail slots, a clamping member slidable on said frame plate toward and away from said flanges, said clamping member being formed of two superposed plates, spurs removably nae-ease secured between said plates and projecting beyond the forward edges thereof, each of the plates being formed with grooves, and the grooves of one plate cooperating with the grooves of the other plate to form socketsgether and means for moving the clamping member longitudinally.

L. A miter clamp comprising a frame plate, flanges mounted, on said plate at right angles therefrom, said flanges converging toward the medial line of the plate and forming a closed angle, the flanges being provided with nail slots, a clamping member slidable on said frame plate and comprising a pair of superposed plates, spurs ren'iovably fitted between said plates, each of the plates being formed with grooves and the grooves of one plate cooperating with the grooves of the other plate to form sockets for the spurs, screws reniovably securing said last mentioned plates to each other, the frame plate bein formed with openin s with which said screws are adapted to register and means for moving the clamping member longitu dinally.

In testimony whereof I aflix my signature.
