I?) all whom it may con-com:

Be it known that 1, Joint AUGUST LU- rnnn, a citizen of the United States, residing at Schenectady, in the county of Schenectady and State of New York, have invented new and useful Improvements in Paper Cutting; and Shaping llalachines, of which the following is a specification.

ll'l'y invention relates to a paper cutting and shaping machine, designed especially for cutting and. forming paper automatically in any desired form or shape in a single operation, such, for instance. as in the cutting out and shaping of milk bottle caps having depressed centers and channeled rims and in the production of other articles Where the paper is out out and simultane ously given a required shape.

in shaping paper articles the best results are gained by first steaming or otherwise moist-suing the paper and then subjecting the same to the action of a heated die, Whereby the desired shape or form is imparted thereto, the most cfllcient action being obtained by maintaining the die for a. given period in contact with the paper so as to drive out the moisture and give the paper its final and completed form.

The object of my invention is to provide a machine which will take the paper in sheet form or otherwise, as it is fed up'and simultaneously cut out the section of paper desired and impart the required shape thereto, and whereby the heating and forming die will be maintained in contact with the paper for the requisite period to dry out the moisture and leave the paper in finished form.

A further object of the invention is to provide a machine in which two or more dies of a unit may be alternately operated from a driving mechanism. and wherein any number of units of the character described may be employed, Within reasonable li1nits, and operated from the same driving mechanism.

The invention consists of the features of construction. combination and arrangement oi parts herein fully described and claimed, reference being bad to the accompanying drawings in which Figure l is a top plan view of a. paper cutting and shaping machine embodying my invention. Fig. 2 is a side elevation of the same. Fig. 3 is an opposite side elevation. Fig. 4 is a vertical longitudinal section on or cutting and shaping devices. In the present instance I have shown in detail one conr plete main unit A. and adjacent units B and U, three in all, only suliicient of the units B and C being shown to illustrate the mode of operating a plurality of units from a conunon source of power.

The portion of the frame Work constituting a part of the unit A is of oblong rectan gular form and provides a working space or opening 2. At the opposite ends of this space are arranged stationary die members 3, each, adapted for cooperation with a inovable 0r reciprocating die member t carried by a head 5 fitted to slide in or upon suitable quides 6. These dies are of suitable form to'cut out the blank from a sheet oi paper and press it into the desired form. and are heated in any preferred manner for the purpose of drying out the moist paper to give a finished set to the article Means for heating the dies is not herein shown, as it specifically constitutes no part of the present invention.

Rods or stems 7 connect the respective movable die carrier heads with cranks 8 upon the lower ends of vertical shafts 9 suitably journaled upon the frame, Where-- by on each complete revolution of each shaft the movable die actuated thereby will be moved out on its working Stroke and then retracted to allow the paper to be fed up for the next ensuing operation. On the shafts '0, which are arranged on opposite sides of the center of the working space 2, are spur gears 10 which are adapted to mesh with a motion. transmittins gear 11. The gear 11 is mounted horizontally upon a vertical shalt l2 '{n'ovided at its upper end with a beveled near 13 meshing with a beveled gear 14: on a driving shaft 15 which may receive motion from any suitable source of power. This shaft 15 is provided with av fly Wheel 16 and carries a driving gear 17 for com illuminating driving motion to gears 18. con stitutiug the driving gears of the units B and whereby all three units may be on ended in unison.

, rotate the other gear 10, the gears of the respective movable dies being thereby alternately and successively operated by the mutilated gear. The number of teeth ,11 is sufficient to retract. each movable die and 7 then project it again, and the arrangement of the said teeth 11. is such that after it -operates each movable die head a dwell or pause occurs fora determined interim before it again engages and operates said die, head, during which dwell, pause or interim the movable die remains projected and in contact with the paper blank which has been out out and is being shaped or formed. This period of dwell is especially provided for in order to allow the movable die to remain for a sufficient period in contact with the work.

to drive out the moisture from the paper,

and thus give a finished set to the article hefore it is discharged or removed from the gearing 34 with the shaft 21'.

, machine. By this means articles which are accurately formed, and are thoroughly dried out so that they will retain their given shape,'may-be produced with maximum reliability and efliciency.

The blank is cutout in practice from a -moving web or strip 20 of paper supplied from a roll- 21. The freeend of the paper fed from the roll passes through a steam box 22 .on its feed to the dies, and hence the paper is moistened to a desired degree. The

feeding end of the paper strip runs in contact with a guide-roll or idler 23 and with a cooperating feed roll 24 on a shaft 25 carry ing a beveled gear 26 meshing with a similar gear 27 on a feed transmission shaft 28, which is operated during the retractive motion of the movable die to feed thepaper f forward to a point between the fixed and movable. dies, as will be readily understood. 1 'Motion'is transmitted to the shaft 28 and simultaneously to the shaft 21 of the paper roll from the shaft 9 of the cooperating die head bymeans of a shaft 29 connected to the shaft 9 by intermeshing beveled gears 30, with the shaft 28 by worm gearin 31: and Y with ai-shaft 32 by means of wor gearing 33, said shaft 32 being connected bybeveled l'bwill has be understood that in' the operation of each-unit of the machine,each,

movable diemember will be retracted, the paper then fed up to a position between the stationary. and movable die members by means ofthe paper feedingmechanism just described, the paper being moistened on its passage through thesteam box 22, and the.

the teeth of the actuating gear 11 will pass "beyond the teeth of the cooperating trans- .relatively adjusted for cooperation to form .a given time.

or reasonable number of units may be em- .ployed to vary the working capacity of the movable die member being then projected so as to force the paper against'the station-- ary die, whereby the blank will be cut out and simultaneously shaped. At this point mission gear'lO, and accordingly the movable .die will remain projected while the other movable. die is being retracted and projected for cooperation with the other stationary die, the dwell or period of rest a of the first-mentioned die being sufiicient to effect the heating and drying of the paper blank so that a proper set will be imparted thereto to render the shaping permanent, by means of which accurately formed articles may be produced. While one set of dies is in a relative state of rest for the shaping operation, the other set of dies is being and shape another blank, and this action of alternately. and successively actuating the opposite sets'of dies is carried out continuously during the Working period of the machine,jthereby enabling a large number of articles to be out out and shaped within As hereinbefore described, the units B and C may be operated simul taneously'with' the unit A, and any desired machine as desired.

It will, of course,ibe understood that the machine may be used for making various -.-kinds of cut-out and shaped paper articles,

from cardboard, paper pulp, and other similar kinds of paper. In Fig. 6 I have shown a form of'bottle cap 35 constituting oneof many different articles which may be made, said" cap being provided with a' 'de'105 pressed center 36'and a raised channeled rim 3?. It will be understood from this disclosure that the'paper to form thecap is cut out as a circular blank and the cap i I then shaped by the action of .the dies, the

moistening and subsequent heating and drying of the paper resultingin a permanent set being obtained whereby the. cap will preserve its form. I
