the head standard 1 and the tail standard 2, gully connected by the pair of cylindritubular bars 3 and 4-, which are rigidly ared in said standards by nuts 6 and 7.

The head stock 9 is conveniently a casting having split bearings 10 fitted to said bars 3 and and arranged to be clamped thereon by screws 12. Said head stock 9 has the bear-i 's and 16 for the rotary head mandrel which is neyented from axial move- .ient therein by the

collars

18 and 19, and idly connected with the cone clutch Her 20 which fits within the conical seat belt wheel 22 by which it nay be Said belt wheel is loose and axial- .znovahlo on said mandrel 17 but has the with axially opposite inclined sures for alternate engagement with the two radial arms of the rock lever 2-1 which is ifulcrumed in said standard 1 and provided with the spring L5 which normally rocks it to axially shift the clutch belt wheel 22 to the right in Fig. I to release it from said mandrel. However, said rock lever may he tilted to the position shown in Fig. I, in opposition to its spring 25, to thrust said clutch wheel 22 to the left in Fig. I and operatively connect it with said mandrel 17, by means ot the lever 26 wiich is tulcrumed in the boa 27 on said head stock 9 and provided with the chain 28 extending to a pedal 29, which is depressed by the operator at the beginning of the cutting operation and released at the end of said operation.

The tail stock 30 has the bearings 31 fitted to slide on said. bars 3 and l, and has the bearings 32 and for the rotary and axially rcci n-ocatory tail mandrel 34. Said mandrel has the collar 86 rigidly secured thereon as an abutment tor the spring 3'? which bears against the loose collar 38 abutting saio 33, and is arranged to continually said tail mandrel toward the conveniently comprising a circuui'licrentially extending line engraved thereon. The gauge plate 4.5 has the pointer 4:6 arranged to cooperate with said gauge marl; 43, and said gauge plate is arranged to be adjustably secured. in rigid relation with the tail stock 30 by the screws 48 extending from the bearing 33 on said stock through the slot 50 in said plate.

t is to be understood that the arrangement last above described is such that said tail mandrel 34: may be manually axially withdrawn to the right in Figs. 1 and Ill. by its milled head 39, to permit the rollcore 32 to be inserted between said mandrels, and upon releasing); said tail mandrel 34, it is thrust into engagement with said core by its spring 37.

V 0 pre'le to provide the opposed ends of said numdrels 17 and 34 with respective polygonal. (con *eniently square) core ongaging adapters 53 and 54: tor engagement with the tubular core 52 which is conveniently formed of molded hard rubber with an axial opening; 57 theretln-ough oi the cross sectional clmligurationv oi? said polygonal ada dei-s; whereby a series of such cores may be succiv vely engaged between said mandrels, in adpistably prcdeterniined axial position.

f'laid cores are made oi? different lengths, in accordance with the width oil. the web to he wound thereon. However, there is a slight variation in the actual lengths of the cores of each stanoard size incident to inaccuraci a in the manufacture of the cores and to the extent of one thirty-second of an inch, which is the tolerance accepted by the trade. 'liheretorc, we provide means to shift said tail stock 30 tmvard and away from the head stock 9 to not only permit the same nuurhine to be used tor trimming the different standard widths of paper or other web above contcin ilatrd; but to compensate tor the accidental variations in size of the cores 52; so that the web shall be trimmed flush with the ends of the cores, regardless of the variations in the length of the latter, and as follows: Said tail stock 30, which is tree i0 slide longitudinally upon said frame bars 3 and 4-, has the nut 59 detachably rigidly connected therewith by the tap bolt 60, which extends through the washer 6i and the horizontal web of said tail stock 30 into screw threaded engagiui'ient with said nut 59 as indicated in lli V. Said nut 59 is engaged with the screw shalt 63, which journaled in the bearing (34: in said standard 2, as indicated in Fig. V. and provided with. the collar (56 upon the let't hand side of said bearing and the hand. wheel 67 upon the other side; whereby said shaft 63 may be turned to shift said tail stock 30 toward and away from the head stock 9.

The rock shalt (39 extends parallel with the axis of said mandrels and is journaled in the bearings 70 and 71 on said

standards

1 and 2, and extends through the bearing 72 on said tail stock 30 and is prevented from axial movement by the collars 73 and 74-, which abut against said bearings 7 O and 71, and are axially adjustably secured thereon by respective set screws 7 6. Said rock shaft 69 carries the two cutter heads 78 and 79, having

respective keys

81 and 82 engaged in the lce'vway in said shaft. Said outter head i8 l as the set screw 85 whereby it may be set ircd in rigid relation with said shaft G9 when set in the proper position, shown in hig. l, but is axially adjustable on said sha'tt when said set screw is released. c aid cutter headv 79 is provided with the sleeve 86 extending through said bearing 72 and provided with the collar 87 at the right hand end oi said sleeve; sothat said. head 79 is carried to ard and away trom said head 78 by rotation of the hand wheel (37 and screw shaft 63 above described.

Said cutter heads 78 and 79 carry respeciw: taco plates 89 and 90 which are rotataly adjustable on said heads to the extent the urcuate slots 91 in said plates, through which extend set screws 92 by which raid plates Said rock shalt o9 has the lever 95) whereby said c tters may be manually pressed :lSZttlilSt? the roll oi carbon paper, or other ch carried by said core betwee said 'iandrels l7 and 3%; said. lever having the spring lOl extending from the rear end thereof to the rod 102 on said head stock 9 and continually tending; to turn said rock shalt to uplitt said cntte's trom operative position, when said lever released.

As shown in Fig. I; the ends r said bcarings bars 9st adjoining said cutters e? are wedge shaped at 103 to press axially outward the i: innned oil portions 104. of said web lOtl. In order to prevent said CUtLOl'S 97 from penetrating

d core

52, 1 provide the adjustable stop screw 105 in the bracket 1%, which is rigidly connected with said h ead stock 9. Said. screw may be to limit the approach of said cutters to said core and be secured in such adjusted position by the not 107. i

It is to be understood that said cutter head 78 is so set upon said rock sh aft (if) tl ii; the cutter 97 carried thereby is always presented in the proper plane to trim the left ltli hand end of said roll of web 100 as desired. However, said cutter head 79 being adjustable toward and away from said cutter head 78 by rotation of said hand wheel 67 and screw (53 as above described; the pointer 46 is so set upon the tail stock 30 that the gauge mark 43 on the hub of the knob 89 0f the mandrel 3d registers with said pointer only when the cutter 97, carried by said cutter head 79, is presented in proper position to trim the right hand end of said Web 100. That is to say; the axial position of said aanerel 34 with respect to the mandrel 17 will, of course, vary with the aforesaid acll( al variations in the lengths of the 52, and the tail stock 30 carrying the right hand cutter 97 is axially adjustable, by rotation the hand wheel (37, with refen once to said mandrel 34 and the gauge mark carried by it; to insure the presentation of the right hand cutter in the proper position with reference to said cores in correspondence with the accidental variations in the length of the latter.

The mechanism above described may be operated as follows: A roll l()() of carbon paper, carried by a core 52, is inserted be tween said inandrels 17 and the latter being first retracted by its milled head 39 and then released to permit both adapters 53 and 5a to enter the opposite ends of the axial opening 57 of said core under prespure of the spring 37 hearing against the 36 on said mandrel 34:. If said core is a the predetermined. standard length; the gauge mark 43 encircling the hub of said head is presented in registry with the index pointer 4.0. However, if said. core is longer or shorter than its i'iominal size, that fact is manifested by the relative posit-ion of said mark and pointer, and, thereupon, the operator turns the hand wheel 67 to brir rid pointer 46 into registry with said The operator starts positive rothe mandrel 17 by depressing the a 43. f course, rotation of said mandrel l7 in engagement with said core 52, causes latter to idly rotate said mandre" 'lhercupon, said lever 99 is depressed by the hand of the operator, in opposition to the stress of said spring 101, thus bringsaid cutters 97 into contact with the outer convolution of the roll of carbon paper 100. The operator continues to thus press said cutters 97 against the carbon paper 100 wih the ell'ect of uniformly trimming the iner at each end at right angles to the common axis of notation of said mandrels, said lever 99 comes to rest upon the v 105, which has been so set that said cutters 97 penetrate the innermost convolution of said paper 100, without cutt g the core 52. Thereupon, the operator stops the re ion of said mandrcls, by role" the pe al 29; and removes the core with the trimmed roll 100, by again retracting the mandrel 34 by its head 39. Thereupon, the entire operation above described may be repeated.

As it is necessary to sharpen the cutters 97, they are, of course, reduced in diameter by each successive sharpening operation, and though originally of the same diameter, may be thus reduced to different diameters Therefore, the capacity of said face plates 89 and 90 for relative rotary adjustment, is advantageous in that it permits said plates to be so adjusted as to simultaneously present said cutters 97 in contact with the web roll 100, regardless of any differences in diameters of said cutters.

We do not desire to limit ourselves to the precise details of construction and arrangement herein set forth, as it is obvious that various modifications may be made therein without departing from the essential features of our invention, as defined in the appended claims.
