MACHINE FOR MAKING PALLE BXLES.

TO ALL WHOMy IT MAY CONCERlz` Be it known-that I, CHARLES B. HATFIELD, ofgthe city and conty of Philadelphia, in the State of Penn- "sylrania, have invented anew' and useful 'Improvement in Machineryfor Making` Paper Boxes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which make part of this speciication, and in whichl i i Figure 1 represents aplan or top view of my improved machine, the red lines showing'the sliding frame as retracted. i i A i Figure 2 represents a View in elevationot the same, as seen from the front, the red lines showing the headholder in contact with the chuck.V l i Figure 3 represents a face view of the head-holder, and

Figure 4 a similar view ot' the holding-chuck.

It is well'known to paper-boxmanufacturers that boxes, the tops and bottoms of which project beyond the cylindrical body, have hitherto been so expensive and diicult to finishneatly that they have been imported from France, andhave thus come to be designated as AFrenchdge b0xes.' i

A It is the object of myv invent-ion'to finish by machinery paper boxes called technically French-edge boxes, and therefore call this machine the ,FrenclrEdge Machine.

My said improvement consists, first, in a chuck or head (toreceive'and carry the sides or body ofthe box) rotating in a fixed relation to but projecting beyond its supporting-frame so as to leave room for putting the boxon and taking it off without moving the head; second,.in combining with a rotating liolding-chuck a device for discharging the box wheniformed; third, in a vibrating head-holder for receiving the box-head and holding it against the holding-chuck which carries the body of the box; fourth, in combining a vibrating head-holder with a vibrating holding-frameso arranged that when the holder has been forced against the chuck the frame is withdrawn to leave room for the other parts of the mechanism to advance; fifth, in a flanged former or head mounted in a sliding frame, androtated Aby its pressure against the holding-chuck, to paste the strip on the box and to turn over the edge ofthe paper to unite the head and sides of the box; sixth, in so combining a. rotating fixed chuck, a rotating traversing former, anda vibrating head-holdcr that the sides and head et' the box are united. by one continuousoperation.

A paper box consisting of two parts, a top and bottom, the one being a counterpart of the other, speakv of the head and sides only, for convenience, it being `obvious that the bottom and sides are made by the saine` process exactly, and that one expression may be used indilferently for both.

In the accompanying drawings, which show one convenient way of carrying out thc objects of my invention, the holding-chuck A for receiving the body ofthe box is shown as rotating on one end of a shaft, R, turning in proper bearings in a strong frame, P. The forming-chuck or presser-head B is formed with a Bange, b,`on^its outer edge, and with a groove, 6 2, between the head and ang'e, as shown inthe drawings, and is mounted on one end of shaft, S, rotating in proper bearings in a frame, C, which slides on the frame P. A coiled spring, Y, on the shaft S, keeps the presser-head B drawn in towards the frame so that its ilange may press against the face ot' the chuck A, andiyet allow it to yield enough to accommodate 4the thickness of the head of thc box. The sliding-frame C is retracted by a cord, L, passing over a pulley, d, and connected to a foot-lever, L. It isdrawn forward again by springs A vibrating head-holder or disk-recciver, F, is hinged to the frame at T, so

las to string towards'and from the chuck A, against which, when thrown up, it is held by 'a catch, a, and spring detent bl, lThe,head-holder F is drawn down when released by a spring, s, at its hack. This receiver F may be ot' anysize or form requisite for' thc particular' box ybeing finished. lhis/ holder when drawn down rests ina vibrating lmlder-i`rarne, E, hinged concentrically with holder F, and is pressed outward from the frame by a spring, d. '.lhe presser-oil vconsists of a series of ribs, p, arranged radially and parallel to the axis of the shaft v t upon a ring, P', which rotates with the-axis, being pressed outwards by the lever X and inwards by a coiled spring, X', tig. 2. These ribs work endwiso through radial slots in the chuck A to press oii` the box when finished,

The operation of the machine is as follows: The parts being in the position shown in iig. 1, the operator places the disk to form the top `or bottom of the box (which disks have been cut to a proper size) in thc headholder Gr, which forms part of the disk-receiver F.. The sliding-pieces m can bc moved in or out to adapt thc holder E to receive disks of varying sizes. The sliding-frame C having been retracted, the ring forming the sides of the box (which has been already formed) is then slipped on the chuck A, its inner edge resting on the shoulders of the presser-oli` P. The holder E, with the-receiver F, carrying the top ofthe box, is then struck up against the face ofthe chuck A by a smart blow'froin the hand oi the workman; the spring detent l catches in the hook a and holds the disk-receiver F with the box-head firmly against the face of the chuck A, while the holding-frame E flies back to its original position. One end ef a properly-glued or pasted strip of paper somewhat wider than the height of the box is then placed n the ring on the chuck, and lby means of the crunkhandle D the chuck is turned about a quarter of a revolution. The frame C is thenreleased and its spring presses the former B against the chuck A. The continuous rotation of the chuck A causes the glued strip to adhere to the ring on the chuck, while the presser-roller lor former B presses it out smoothly, and the flange b turns the projecting edge of the paper strip over and presses it against'thc disk or head, thus uniting the two securely. The projecting rim of the box enters the groove J on the former, and is thus protected from injury. The frame C is now retracted and the holder F released, when it Hi'es back toits position in the holder-frame E. The lever X is then moved outward from the frame and presses the box oil' the chuck A, when everything is ready for a repetition ol' the operation above described. .l

It will thus be seen that by my invention I am enabled to use la chuck revolving in a fixed, position; to obtain ample room for applying the ring thereto; that the holder keeps the disk securely in place, and that the retracting former leaves room at the proper time for the vibrating holder-frame to work, and unites the top and sides of the box smoothly and securely.

By a mere adaptation of form in the receiver-F square boxes or oval boxes may be made in the manner herein described, the skill of the operator being all that is-requisitc in Working it, and I do not, therefore, confine myself to round boxes. I

W'hat I claim as my invention, and desire to secure by Letters Patent in a. machine for finishing Frenchedge paper boxes, is-

l. A chuck or box-holder, A, arranged to rotate in a fixed position outside of the frame I), substantially :is described.

2. The combination, substantially as described, of a slotted chuck rotating in a fixed position, with a presser-olf rotating concentrically with the chuck, having an endwise motion on itsaxis.l

3. A vibrating head-holder or disk-receiver, arranged substantially as described, for the purpose of holding the disk to form the head of the box against the ring constituting its sides.

4. rlhe combination, substantially as and for the purpose described, ot'a vibrating disk-receivor or headholder, with a vibrating holding-frame.

5. The combination ofthe chuck A, flanged and grooved former B, and sliding-frame C, when arranged and operating substantially as described.

6. The combination, substantially as described, of a chuck rotating in a fixed position outside the frame, a rotating former mounted in a traversing-frame, and a vibrating head-holder or disk-receiver, for the purpose of uniting the head and sides of the box by a single continuous operation.

In testimony whereof` I have hercuntosubscribed my name.

C. B. HATFIELD.
