CUTTING MACHINE.

application filed December I, 1925, Serial No. 72,436, and in France December 17, 1924.

'llhis invention refers to machines comprising a press and a tool for cutting or working; in any manner upon the maternal being pressed; and relates more particularly, although not exclusively, to machines of this type for cutting or clipping paper, card board and other like material, as it is in the case of such material that the machine would appear to offer the greatest advantages.

It has for its object, to so construct such machines that they respond in a more satis factory manner than has hitherto been the case to practical industrial requirement-s.

According to the general principle of the invention, machines of the class in question are so constructed that there is interposed in the driving train between the press on the one hand and the tool on the other hand, cpicyclic gearing, so that suitable pressure on a pile of the material to be treated can he scoured. irrespective of the heightof such pile within the limits imposed by the size of the machine. Such suitable pressure is secured during thc'cntire period of operation of the device, without any adjustment. of the press with respect to the height of the pile of u'iaterial, in order to ensure the necessary pressure upon the said pile. Use made of the reaction resulting from the resistance encountered by the n'loving part or parts of the device. as a force for ensuring the necessary pressure for pressing and u'iaintaining the action upon the said materials, the said force increasing with the resistance encoun te (d by the tool. The pressure exerted by tie press on the materials to he treated can he varied at will according to the nature of the work to be performed.

The invention consists, in addition to the principal feature already stated, of certain other features which are preferably utilized at the same time and which will he more full descrihed hereafter.

it includes more particularly certain methods of application (those in which the invention is ap lied to cutting or trimming mach nes for paper. cardboard and like ma tcricli and to certain constructional ernhcdi shown) T he in the H ments of its principles (which will be more fully set out hereafter); and it includes in particular, and as new industrial products, machines ot the class in question including the application of such arrangements, special parts and tools adapted for their construc- 'tion.

The invention will, in any case, be well llJlClGIFShOOd by means of the following de scription, as well as from the annexed drawings, which description and drawings are, it is to he clearly understood, merely given hy way of example.

Fig-I. 1 is a diagrammatic vertical elevation partially in section, of the essential parts of a machine constructed according to my invention, this view heing taken on the line l.-1 of Fig. 2.

liip'. :2 is a. vertical section on the line 2--2 of Fig. 3.

l igz. 3 is a denil view showing another embodiment of the hralte control mechanism.

According to the invention, and more particularly according to those methods of ap plication and, to those constructional emhodi- Jucuts of its various features to which it would appear that preference should he 'QjlVGYI. in coiistrucit-inc a machine for cutting piles of paper, to the following principles of constiuiotion.

'lhe general construction includes a framework 1 of suitable shape, size, and strength. 2 is a primary shaft mounted in hearinpjs in the framework. horizontally for instance. This shaft has coi'mnunicated to one end thereof the. motion from a motor (not primary shaft 52 carries a pinion 3 the other end thereof.

4- is near or toothed annulus adapted to mesh with the pinion 3 and mounted loosely with respect to the first aligned shaft 5 which parallel to the shaft 2 and is mounted in hearings on the framework. The

annulus t is fixed to a casing 6 revolulole with respect to the shaft 5 and also mounted upon and revoluhle with respect to a second firmed separate therefrom, located with shaft 5 and also mounted lid in hearings on the framework. This casing 6 is adapted to contain a set of epicyclic gearing of any desired type, for instance of 'the planetary type, and consisting of two planet bevel gears 8 fixed respectively to the shafts and 7 and by two sun bevel gears 9 mounted on spindles perpendicular to the previously mentioned shafts and carried by the said casing, so that said sun bevel gears can freely revolve in casing 6.

10 are two vertical racks fixed tothe platen 11 of the press and adapted to'mesh resp'ec- Y framework and; adapted to be rotated by the shaft: 5; means of two gears 15' and 1.6, meshing with one another and fixed respectively upon the said shafts 14 and 5. The

sh-aft 1 4 operatesthe vertically movable knife by" means of two crank pins 17 and two connectingrods- 19. One of said pins 17 is mounted upon the toothed wheel 15, and the other of them is mounted upon a disc 18 which will be mentioned hereafter. The slide which carries the vertically movable knife 20 and the plate 11 ofthe press, is located above a horizontal table 21 carried by v the framework.

22 is a fly wheel mounted on the shaft 5 and adapted as will be seen hereafter to be acted upon by a brake or tobe allowed to run freely.

Means are also provided for connecting the shaft 2 to the driving shaft or for disconnecting it therefrom. These means include for instance, a member 23 connected to said shaft 2 by'a longitudinally slidable key and adapted to be, connected tothe said driving shaft by any suitable clutch means. Such means may for instance include. conical clutch elements, and member 23 may be released whenit is moved into. a conical recess 24 provided for the purpose in the framework.

25 is a lever pivoted to theframework and furnished. with a fork at one of its extremities. This. fork engages a groove provided for the purpose in the member 23 so as to actuate said member 23 to and fro. At its other end the lever 25 is provided with an edge adapted to be engaged by or released from an engaging hook 26. The disc 18 is provided with a boss or projection which operates. upon the said hook 26 to disconnect it from lever 25. I

The spring 27 then moves member 23, into the inoperative position so that shaft 2' is disconnected from the drawing shaft. Means are provided for enabling the fly wheel 22 to be subjected more or less to a braking action or to be allowed to run freely.

The means in question may be of various kinds, but may be for example of one of the following As shown in Figs. 1 and 2, the fly wheel 22 is furnished with two brake shoes 28 pivoted together by means of a pivot pin 29 fixed to the framework. 30 is a cam member adapted to operate these brake shoes and connected to a lever 31.

A cam 32 is mounted on shaft 14:, half of said cam having a circular contour, the

other half thereof being tapered as shown in Fig. 1. the greatest radius of said tapered portion being less than the radius of said circular portion. A spring 33 tends to force the brake shoes 28 into the operative or braking position. Since the movement of the brake shoes turns the cam 30 and the attached lever 31, said spring 37 causes lever B1 to contact with cam 32. Hence, the brake shoim are movedto the inoperative position during substantially a half-revolution of the shaft 14, when the lever 31 is moved in a counterclockwise direction by cam 32. Likewise, the circular portion of cam 32 forces lever 31 to a position in which cam 30 forces the brake shoes 28 to the inoperative position, during the second half-revolution of shaft 14:, and while the crank pins 17 are moving from lower dead center to upper dead center. The brake pressure is greater when crank pins 17 are in substantially the position shown in Fig. 1, due to the shape of cam 32.

As an alternative, and as shown at Fig. 3, there may be provided an arrangement suchas that already described, that is to say two brake shoes 28, a cam 30 for oper atingthese brake shoes, a lever 31. a cam 32 and a. spring 33 for forcing the brake shoes to operative position. but with th s difference that the freeextremity of the lever 31 in this case enters a notch 36 as hereafter mentioned. In addition an auxiliary mechanism is provided including a bcll crank lever 34 pivoted, to a fixed portion of the framework by means of a pivot pin 35 parallel to the shafts previously mentioned. This hell-crank lever has one of its arms provided with the notch 36 just mentioned. Then the lever 31 is engaged by the notched end of lever 34;, said lever Si is kept in this position by a suitably arranged tension spring 37 The other arm of the said lever 34 is adapted to be moved in the direction in which it liberates the lever 31 by an. arm 38 attached to the hub of one of the gears 12. 39 is a lever pivoted at :0 to u. lived part of the framework, and adapted to oscillate under the action of the cam similar to the lever 31 of the previous arrangement. This: lever 39 is also pivotally (mum-ted to a, link 4-1. which is pivoted to a lever 42 mounted loosely on the shaft of can) 30, and provided with a projecting finger 4-3 adapted at a predetermined moment to come into :ill)

stoppage of the press at any point of its course according to the thickness of the material to be cut.

Pressure adjustable at Will according to the work to be carried out.

Increase in the automatic character of the working of the press, the pressure exerted being increased as a function of the resistance encountered by the knife during its cutting stroke.

Grreat ecomony in driving power, since a.

very large proportion of the pressure is produced by'the reaction due to the cutting action of the blade.

Aswill be clearly understood, and as has already been pointed out, the invention is not limited in any way to those applications or to those constructional embodiments of its various principles which have been more particularly described herein. It includes all modifications coming with-in a fair inter pretation of the claims, and it is to be observed that the transmission mechanisms may be of any desired description, those L shown on the drawings being represented planetary gearing having separate elements separately connected to said clamping member and to said cutting member, and brake means adapted to check the movement of one of the elements of said train of gearing.
