HENRY WEBER OF CHICAGO, ILLINOIS, ASSIG-NOR TO LATHAIVI MACHINERY COMPANY,

OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS. t

I To all whom it may concern:

zen of the United States, residing s f WIBE-ST'APLING MACHINE.

W BER, a citiat Chicago, county of C0ok,and State ofIllinois, have invented certain new and useful Improve- Ma chines, of'which' Be it known that I, HENRY fica'tion. A

' This invention relates to wire stapling machines of the class shown and described in my -U. S. Letters Patent N 0. 683,823,

issued October 1, 1901, and isdesigned as an improvement thereon. i

The improvements relate to the means for guiding the wire properly into position on the anvil,

aswellas to features of minor 1 importance hereinafter pointed out.

201 while a former which embraces the anvil,

and, by engaging home by a suitable driver.

The anvil, in the usual machine of this class, is provided witha slot open at one side, into which the wire is projected and rests,

the projecting ends of the wire, turns said ends downwardly to produce the staple, which is thereafter forced This former has at grooves in its opposed faces arranged length r position directly 1 in wise of its line of movement receiving the ends of the stapleand holding and guiding the same while the staple is driven, and it is found to be quite diflicult occupy a to at all times line with to induce the wire these grooves, at the start.

.One object of the invention, therefore, is for holding the grooves of the former after it is placed on the anvil or and "the accomplishment within the groove of theanvil.

With a viewto the attainment of this end, of certain other objects which will hereinafter appear, the

- invention] consists in certain features of "novelty in the construction,

combination, and arrangement of parts, which willnow be described with reference to the accompanying drawings, and more a pointed out in the clalms.

according to this invention;

particularly In the said drawings, Figure l is a front elevation ofa partofawire stapling machine, partially broken away, constructed Fig. 2 is a detail perspective view of a wire guide hereinafter described; Fig. 3 is-an enlarged side and in line with, the inner end of the slot in the anvil, for

elevation of a part of a wire stapling machme embodying my invention, partially broken away, and disclosing the wire guide; Fig. 4 is a section taken on line 4, 4, of Fig. .1.-Fig. is a detail of the construction shown in the lowerpart of Fig. 4, to show the staple former provided with grooves, with which the wlre must come into alinement when it 1s properly positioned in the anvil member.

e wire from which the staples are formed may be stored on spoolor reel, as

usual in machines of this type, and not necessary to illustrate or describe herein, and

from this reel it is fed through suitable guide passages to a tube or passage, which is usually constituted by a section of tube 1, screwed into the frame portion 2, for holding the wire preparatory to being severed by the wire knife 3, all as usual in machines of this kind. The wire in its passage to the tube 1 runs over a fixed support 4, over which is arranged a holding dog in the form of a serrated wheel 5, pivoted in an arm 6 in such a manner that wire attempt to make a retrograde or backward movement, and

may freely move upwardly away from the support in the direction of feeding movement of the wire, 5 being prevented by any suitable means, such as a set-screw 7 screwed through the side of' the arm 6. From the support 4, the wire passes overa second support 8, which is suitably mounted upon a pair of guide-rods 9, 10, as usual, and over which support is arranged of a serrated wheel 11 mounted in a pivoted arm 12, as usual, allow the dog 11 to move upwardly in the direction of m0vement of the wire, but to grip the wireagainst the seat or support 8 for preventing a relative rearward movement between the wire and the feeding dog.
