band-iron in the manufacture of grilled work and so-called Venetian ironwork, and to make a simple single tool to take the place of the several devices usually employed in this class of work. A

In the drawings,in which the same letters refer to the same parts in all of the views, Figure 1 is a side elevation of my device with a portion of the base-plate in partial section and With the end of the lever removed, Fig.'

2 is an elevation of the other side of a portion of the tool, showing the location of the knife.- Fig. 3 is an enlarged detail view of the bifurcated end of the actuating-lever. Fig. 1t is a top plan view of the upper jaw of the binder. Fig. 5 is a side view of the upper portion of the bar, showing the collar of the upper jaw in section. Fig. 6 is a perspective view of the upper portion of the bar. Fig. 7 is a detached perspective view of the clutch of the upper jaw. Fig. 8 is an enlarged side view showing the relative positions of the jaw, the iron bands, and the binder before action 5 and Fig. 9 is asimilar View showing their position after action.

In the drawings, A is a standard consisting of a bed-plate ct, supporting a guide-head a, and a base-plate ct,united by a vertical plate c". The base-plate a is provided with-a central vertical socket s, adapted to receive a" coiled spring s'. The gu ide-head a is proand around which is coiled the spring s', and two central parts, the upper one of which, r', is square or rectangular in section and about the width o f the diameter of the part r, and

the lower one of which, r", may be of any shape in section, but which must be of suflicient size to -prevent its passage upward through the slot in the guide-head et and the lowermost portion of which affords a place of abutment for the upper end ot' the spring 6o s'. The bar R is provided with lugs P and P', the purposes of which will presently appear. To each side of the vertical plate a" is pivotally secured a lever L, which isrbifurcated and slotted at Z and l to admit'of the passage 65 of the lugs P and P'. The outer extremity of the lever is not shown in the` drawings. As will readily be seen, the upward or downward motion of the lever on its pivot will actuate the lugs P and P and through them commu- 7o nicate a reciprocating movement to the bar R, which is normally held in place by the action of the spring s. The lever L is recessed at the inner side of one of its arms,

and in this recess is secured a knife-'edge 75 K by a screw B or other suitable means.

Dprovided with a collar d, adapted to slip over the bar R, and a lower projection d', which forms a jaw, and between the inner face ofpwhich, d, and the bar R is formed a pocket m. Similarly a projection E, having an inner face e, forms,with the bar R, another 9o pocket m. The pockets m and m are preferably of angular form, as shown.

The lmeans which I employ for securing the member D in place on the bar R is a little friction-catch F, loosely pivoted ontop of the memberD atf. This is curved at f and may with the exertion of a little force be moved over a little projecting stud h, normally pressed upward by a spring ,confined in a socket in the member D; The bar R is reroo These two edges K and la, 8o

cessed at g and adapted to receive the end I of the catch, thus preventing its upward movement and securing the member D firmly in place. Vlien it is desired to remove the member D, the catch F is pressed over the stud 71 the catch is throwii out of the recess g, and the collar (Z readily slides upward and oit of the bar.

The method of using my improved tool is as follows: Suppesing that it is desired to unite two or more bands, as N, bythe binder O, the binders are made already bent into U-shaped pieces and are of different sizes to admit of a different number of bands being secured together. rlhe bands N are placed in close Contact and placed within the binder O, so as to be partlyembraeed thereby. The parts thus arranged are placed on the upper edge of the jaw E, so that that portion o" of the binder O rests almost or quite against the bar R. The lever Il is then depressed. This exerts a downward pull upon the bar R,which carries with it the member D and jaw d until the latter is in Contact with one leg o of the binder O. The downward pressure upon the lever being continued, the outer part of the leg 0 is first bent over, as shown in Fig. fi, so as to partly encircle the bands N and bind them closely together. Further pressure being exerted the leg o of the binder() is bent upward against the inner edge of the jaw E and also made to partly encircle the bands N from their lower side. At lhe same time both bands and binder are tightly wedged into the double pocket, formed between the jaws and the bar. The lever now being released, the reaction of the spring s causes the bar R to ily upward and the frictional Contact between the jaw d and the bands usually is sufficient to at once pull the bands out of the pocket. Should it stick, however, a slight pressure ot' the catch F is sufficient to release the jaw d' from the bar I, and thus render the removal of the bands and binder easy.

\Vlien a biiiding-tool is employed which has a fixed upper jaw, it is sometimes extremely diflicultto disengage the jaws and move them away from each other after the binding effect has been accomplished, and a vigorous blow of a hammer is necessary at times to effect this purpose. advantages.

By means of shears formed by the pivoted lever, provided with a knife-edge K and the similar knife-edge set into the vertical plate am, the bands to be united together may be cut any desired length and at any desired angle with great ease, on account ofthe enormous leverage which is gained by the use of the long handle et the lever Ii. The workman is thus enabled to dispense with a separate pair of shears.

That I claim as new is*- l. In a bindiugtool the combination with a bar, of twojaws provided with angular pockets adjoining said bar, and means for bringing the jaws towaid each other.

The combination with a bar carrying a jaw having an angular pocket adjoining said bar, of another jaw also having an angular pocket adjoining said bar and mounted on a guide-liead through which said bar passes.

The combination with a bar and means for moving the saine, of two jaws each provided with an angular pocket adjoining said bar, one detaehably mounted on said bar and the other similarly mounted on the guide for said bar.

et. In a binding-tool the combination with a bar of a jaw provided with an angular pocket adjoining said bar and means for detachably securing the jaw to said bar.

In a bindii'ig-tool the combination willi a bar of two jaws each provided with an angular pocket adjoining said bar, means for actuating said bar and means for normally keeping the jaws apart when not in use.

G. The combination with a standard ofa bar, two jaws provided with pockets adjoining said bar, a lever provided with a knifeedge and adapted to actuate said bar, and a corresponding knife-edge mounted on the Standard.

In testimony whereof I have hereunto set my hand the lith day of December, .1895.
