2 SHEETS$HEET JULIUS J. MILLER-OF ST. JOSEPH, MICH G ASSIGN'OR, BY MESNE ASSIGNMENTS, To WIREBOUNDS PATENTS COMPANY, or KITTERY, MAINE, A CORPORATION OF MAINE.

To all whom it may concern.

Be it known that I, JULIUS J. MILLER, a citizen of the United States of America, and resident of St. Joseph, Berrien county, Michigan, have invented a certain new and useful Improvement in Adjustable Box- Blank Machines, of which the following is a specification.

My invention relates to machines for making wire-bound.boX-blanks of that kind inwhich each blank consists of strips of veneer which are reinforced by cleats secured to the inner surfaces thereof, and which are-connected together by binding wires secured to the outer surfaces thereof, whereby the different sections of the blank are reinforced and flexibly connected together, said cleats being disposed in position to be secured to the end walls of the box.

My invention is applicable to machines of diiferent kindsf I have illustrated my invention in connection with a machine of the general character shown in United States Patent No. 815,197 issued March 13, 1906, and in United States Patent "No. 864,955, issued September 3, 1907.

The object of iny invention is the provision of improved means for quickly and effectively varying the distance between the blocks or other devices for spacing the cleats apart on the wbrk-holderof a machine for making blanks of this character. As herein disclosed, I provide means for permitting a sliding adjustment of the said spacing blocks along the links of the chainsconstituting the traveling work-holder, or along the channels or pockets carried by said chains, whereby the' said work-holder may be used with cleats of different lengths, without the necessity of loosening any of the parts of the chain, or of the pockets or channels carried thereby, and'whereby the machine may be readily and quickly adjusted for the manufacture of box blanks of different sizes.

As will hereinafter more fully appear, I provide each spacing block with a screw, and with means operated by Said screw for engaging the sides of the pockets or channels in which the. blocks are held, whereby the manipulation of the Screws is the only' thing necessary when it is desired to vary the distance between the said blocks.

My invention is in the nature of an im Specification of Letters Patent.

ADJUSTABLE BOX-BLANK MACHINE.

Patented July 11, 1916.

Application filed June 28,1909. Serial No. 504,667.

application of William P. Healy, Serial No. 503,116, filed June 19, 1909..

In the accompanying .drawingsFigure 1 the links of said chain. Fig. 6 is a plan of the same. Fig. 7 is a section on line 7-7 in Fig. 5. Fig. 8 is a section on line 8-8 in Flg. 7. 1

As thus illustrated, the endless link belt or chain A is of the character shown and described in the aforementioned prior patents. The said chain is composed of links provided with pockets or channels B and held together by bolts C, in the well known manner. Each pocket is provided with a spacing block D of the usual or any Suitable form. Each block is provided with avertically disposed screw (Z having a tapered lower end. The tapered lower end of each screw engages the beveled inner end of two oppositely and horizontally disposed retain- 1 ing devices d, which latter project from oppositesides of the block. Theseretaining devices are adapted to engage or impinge upon the inner sides of the pockets or channels B, in the manner shown in Fig. 7,. It will be seen that one of these devices cl, of each block, engages in a. groove 6 in the side wall of the pocket. When the screws are tightened up the devices (Z are forced apart and the blocks are then held inposition in. I

the pockets. By slightly loosening said screws the blocks can be given a'sliding add ustment along the pockets, thus varying the distance between them. In this way the work-holder can be adjusted or changed long cleats are to be used, then theblocks quickly for different lengths of cleats.

are moved apart; but if short cleats are to be used, then the blocks are moved nearer to gether. In doing this it is not necessary to loosen the bolts C, as was necessary in said prior patents.

It follows, therefore, that the blocks are not clamped tightly by the plates of the chain, being free from clamping pressure in this respect. Thus the alteration of the chain work-holder is accomplished quickly iio - length thereof, and free of clamping pres-- gitudinal groove for engaging said means,

and easily and with but very little labor. Box-blanks of different sizes can thereby be made on one and the same machine without loss of time in changing from one size to another.

For the broader purposes of my invention, I do not limit myself to any particular kind of work-holder, although I prefer an endless chain work-holder. 1

By leaving off one of the retaining devices (Z, preferably the one next to the chain, the entire inner face of the block will then bear against the side of the pocket, thereby producing. frictional contact for holding the spacing block in place. This, of course, will leave one retaining device cl in engagement with the groove 1) at theother side of the pocket.

I do not limit myself to the exact construction shown and described.

lV hat I claim as my invention is 1. In a box blank machine, means for making blanks of different sizes, comprising a work-holder having a cleat channel, spacing blocks therefor, adjustable along the sure thereby, and means including a vertical screw in each block for. holding the same in different positions on said work-holder, said work-holder having a. longitudinal groove for engaging said means, the said blocks and means being entirely within the cleat channel of said work-holder,. and each block being formed to engage the opposing ends of two adjacent cleats.

2. In a box blank machine, means for making blanks of different sizes, compris-' .lng a work-holder having a cleat channel,

spacing blocks therefor, adj ustable-along the length thereof, and free of clamping pressure thereby, a screw in each block, and means carried by the blocks and actuated by the lower ends of said screws for holding the blocks in different positions on said work-holder, said work-holder having a loning blocks therefor, adjustable along the lengtlrthereof, a screw for each block, a grooved support for said blocks, and means 'carried by the blocks and actuated by said screws for engaging the groove of sald support tohold the blocks in different positions on said work-h'older, the said blocks and means being entirely within the cleat channel of said work-holder, and each block being. formed to engage the opposing ends of two adjacent cleats.

4. In a box blank machine of'the kind disclosed, a traveling work-holder having a cleat'channel having aplurality of spacing blocks for spacing the cleats apart endwise in the direction of travel thereof, means on the work-holder for *engaging one side of each spacing block, a vertical screw in each spacing block, a retaining member carried by and projecting from the other side of each spacing block, adapted to be operated by said screws, andmeans on said Workholder for engaging said retaining mem-' bers, whereby the distance between the spacingblocks may be varied at will, all Within the cleat channel of said work-holder, and

means for'stapling the blanks as'they move JULIUS J. MILLER.
