' To all whom it ma/y concern:

tutti EBEN JAMES. OE TYNGSBOROUGH, MASSACHUSETTS, ASSIGNOR TO HIMSELF AND W. B. BRINLEY, OF THE SAME PLACE.

Letters Pate/nt No. 84,422, dated November 24, 1868.

Be it known that I, EBEN J AMES, of Tyngsborough, in the county of Middlesex, and State of Massachusetts, have invented new and useful Improvements in a Machine for Manufacturing Boxes; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon,

The nature of my invention consists in the arrangement and combination of the stationary and adjustable cutter-heads, with their gang of cutters, and the adjustable table, as hereinafter described.

To enable others skilled in the art to make anduse my invention, I will proceed to describe its 'construction and operation.

Figure 1 represents a plan of my improved machine for mauufacturingboxes.

Figure 2represents alongitudinal section of the same.

Figure 3 represents a plan of the nished side of a box, showing the Work performed by the machine.

Similar letters in the diiierent figures indicate corresponding parts.

I construct my improved'box-.machine with a suitable frame, a. The sides are connected by the requisite girts.

To the top of this frame a are `secured the boxes, b b and c c, which form bearings for the shafts d and e, to Which are secured the cutter-heads, f and g, with their gang of cutters, h eand 7),- the boxes b 'b being stationary and the boxes o c adjustable, sliding on suitable ways.

By thus having the boxes c c adjustable,the cutterhead g, with its gang of cutters, t i, can be adjusted so as to accommodate and facilitate the manufacture of boxes of various sizes; although, in some cases, it might be preferred to have both ofthe cutter-heads, f andy,

adjustable or stationary, this feature 'being governed and regulated to suit the manufacturer.

The shafts d and e are also .provided with the requisite pulleys, j and k, which are secured to thesame, and connect with the pulleys l and m by suitable belts, these pulleys, l and m, being secured to the drivingshaft n. Also, to this shaft are secured the driving and loose pulleys7 o and p, from which motion is imparted to the machine, this shaft n being located and secured 'in the required bearings to one end of the frame a;

Located between the bearings or boxes, d and e, is

an adjustable table, q, sliding on suitable ways Aor grooves, on which the lumber to be operated upon is placed, which is to form or. construct the boxes, as required. This is held secure in its place, Whilst being operated upon, by the assistance of thehand-wheel fr and its follower, s.

This adjustable table, q, is operated by means of the hand-wheel I, which is connected to the shaft u, which revolves in the required bearings, they being secured to the sides of the frame a.

Secured to the shaft s are the pinions e e, which connect with the racks ww, gearing into the same. These racks are secured to the frame of the table q.

The machine being thus constructed, and its several v parts adjusted in positiomis then ready for use, power which brings the table above .the cutter-heads fl and,

e, by the assistance of the hand-Wheel t, which operates, the -pinions e u in the racks w w, whereby the table g is raised, as required'.

The stock, being saWed and finished smooth, of the required length, Width, and thickness, is placed upon the table q, there being the required gauges provided, which will bring the stock true with the gang of cutters 71. and fi, on the cutter-heads f and g.

The table q is packedfull of these prepared pieces of wood, and held with the assistance of the handwheel lr, with its follower s.

The table q is then depressed by aid of the handwheel t, which brings the wood in contact with the gang of cutters hf h and i t', owing to the great speed they revolve, cutting and finishing, at the same time, both sides of this large number of separate pieces', with a series of straight or square tenons, as shown in iig.

pressure relieved from the pieces', which are then taken from the table q and glued, then puttogether,

thus making a box much stronger thanA otherwise'cau be made; the depth of the tenon being governed by the thickness of stock used.

' Thus, with this arrangement and combination of old devices, I am enabled to furnish boxes at a much cheaper rate, being stronger and far more durable than those now made and in common' use; also, after the pieces have passed by the gang of cutters hh and i i, and nished, as represented in fig.. 3, they'are in condition to be put into the required shape.

I do not claim the several devices separate or distinct, as they are old, and have long been in common use; but

What I do claim as myinvention, and desire to secure by Letters Patent, is-

The combined arrangementy of the two gangs of cutters, h h and t i, one being adjustable toward and from the other, and the table q movable between the said gangs of cutters by means of the crank t, pinions v fu, and racks w fw, all substantially. 'as and for the purpose herein specified.

EBEN JAMES.
