To all whom it may concern:

Be it known that I, JULIUS J. MILLER,

a citizen of the-UnitedStates of America,

and resident of St. Joseph, Berrien county, Michigan,- have invented a certain new and useful Improvement in Wire Bound Box- Blank Machines, of which the following is a specification.

- My invention relates to wire bound box blank machines of that kind in which means are provided for securing the binding wires to the veneer by staples that also fasten the limit the output of a machine of this kind.

The principal object of my invention is, therefore, to provide a machine of such character that a plurality of blanks can be made at the same time and by practically one and the same operation.

It is also an object to provide a construc-. tion whereby the doubling or increase of work done by the machine will not require any more attendants for the operation thereof than the previous machines in which only one blank at a time could be made.

Another object is to provide a box blank machine in which the arrangement is such that the pound of the staplers will be less objectionable than heretofore.

To these and other useful ends, my invention consists in matters hereinafter set forth and claimed.

In the accompanying drawings- Figure 1 is an end elevation of a box blank machine embodying the principles of my invention.

Fig. 2 is a, horizontal section on line 22 in Fig. 1.

Fig. 3 is a detail plan view of the ratchet mechanism at the top of the machine for operating the feed mechanism by which the blank sections are moved forward to be stapled and wired together.

Fig. 4 is a perspective of one of the wire bound blanks.

As thus illustrated, my invention comprises a frame or body A having side portions a connected together by horizontal webs a and a and by. a drive shaft B having a pulley and clutch of any suit- .7' and pitmen y able character by which the machine is driven. A hand lever b is provided for controlling said clutch to start and stop the I machine.

The cleat guides C are arranged one above the other at one side of the longitudinal center of the machine, and the similar guides D are arranged one above the other at the other side of said center. The guides C are separated from the guides D y upright frame members E to which the guides are adjustably secured. The said guides are made of angle iron, and each guide has an overlying guard or plate F which bears on the outer surface of the sheets of veneer 1 to keep the cleats 2 in guides. These staplers are mounted on the,

vertical beams H which are disposed at opposite sides of the guides and which rigidly connect the web a With the web a of the frame. These staplers are operated by the 'cross heads or beams I that are disposed vertically at opposite sides of the machine, and which slide in slots in the webs a and a when the machine is in operation. The

staple wire feed devices .9 are of any suitable character, are operatedin the usual manner by vpawls g carriedon the cross heads 1, whereby the wire 3 is fed for the staples. The binding wires 4 are fed from reels of any suitable character.

To operate the cross heads I a vertical and central shaft J is provided and mounted to rotate in bearings on the webs a and aflthis shaft being between the two sets of cleat guides. At its upper and lower ends said shaft J is connected by, eccentric straps with the ends of the cross heads I, whereby the rotating of said shaft serves to reciprocate the said cross heads and thereby operate the said staplers. The shaft J is connected by bevel gearing K vwith the drive shaft B, whereby all-four staplers are operated from the one shaft.

The mechanism for feeding the blanks along the guides consists of a plurality of link belts L, one for each cleat guide, said belts being provided with teeth that impinge upon the outer surface of the veneer to move the blank along. These fceding bclts or chains are arranged immediately behind the said staplers and are carried on sprockets Z mounted on vertical shafts Z, wh1ch latter have tll(:ll"l')Gi11lI1gS on the. frame. The

v length of contact of the chains L along the v Z fixed on the upper ends of the shafts- Z,

as shown in Fig. 3. The pawl arms Z are movable on the shafts Z, and are suitably connected with the pitman Z whereby the arms are moved back and forth. The dogs or pawls Z on the arms Z engage the said ratchet wheels to give the chains L a stepby-step feeding motion in the direction indicated by the arrows. The pitman Z is operated by a crank arm Z on the upper end of the shaft J, the mechanism being timed to feed the blank forward while the staplers are drawing away from the work. The staples are driven While the blanks are stationary, and during the back stroke of the ratchet pawls Z whereby the desired results are obtained. v

There are different ways of using a machine of this character. For example, the veneer can be preliminarily fastened to the cleats, in any suitable manner and by any suitable machinery, and the blank sections thus made can then be placed by hand in the ends of the guides. The operator will push the inserted section, one at each side, along until the first staples are driven therein, and

' then the sections ahead .will pull the newly wired section through the machine. It is as easy for the operator to place the two sections in the guides as it is to place one section in a single machine. With my double machine the two blanks are made at a time, with their inner surfaces facing each other, and the vertical planes of travel of the parallel blanks are so close together that it is practically as easy for the operator to keep the two runs going as it is one, the machine being what may be called a double run machine. The blanks thus fed through 111 two runs are made ust twice as fast as on an ordinary single run machine, and at practically no increase of labor. \Vhen the veneer is thus preliminarily fastened to the cleats, no spacing devlces are necessary, as

the overhanging edges of the veneer serve as a means for spacing the cleats apart enclwise. But, of course, spacing devices, of

toyed. if desired. 7

machine of this character is characterized. obviousl v'. by just double the output of he ordinary machine in which only one nk is made at a time. Thus the cost of any suitable or well known character, can be niuction of wire bound boxes is materially 1 hid very considerably reduced.

l urthermore,-*the arrangement involves an economical use of shafts and frame. In other wor ds, there is only one eccentric shaft, and only one simple frame, notwithstanding the double capacity of the machine. In this way, and by'reason of the close relation of the two sets of guides, the machine is of a I unitary character. It is what may be called sometimes very violently, to the floor on which the machine stands. With the double opposed staplers, however, as herein shown and described, this diificultyis avoided.

The two paths of travel of the blank may be termed runways, and with the two runways so close together and arranged back to back, the machine isaunit. In fact, the two runways are disposed in operative relations to each other, and by this is meant that they are so disposed relative to each other that the two may be taken care of and operated like one machine, and in conjunction with other elements which are common thereto, or distinguished from two separate machines in which all parts are duplicated, and which require two complete sets of operatives or attendants. Of course, the capacity oroutput in any case may be doubled by using two machines, but that would double the cost of the machinery and the amount of labor required, and would not reduce the cost of production. With my invention, however, theoutput is doubled with only a moderate increase of cost of machinery, and with practically no increase of labor. Consequently, my invention tends to reduce the cost of production of boxes and crates of this or similar haracter.
