GUILLOTINE PAP ER CUTTING AND TRIMMING MACHINE,

SPECIFICATION forming part of Letters Patent No. 567,576, dated September 15, 1896.

Application filed May 11, 1895. Serial No. 548,978. (No model.) i

To all whom it may concern.-

Be it known that I, ALFRED BRADLEY, a subject of the Queen of Great Britain, residing at Elms Road, London, in the county of Surrey, England, have invented certain new and useful Improvements in Guillotine Paper Cutting and Trimming Machines, of which the following is a specification.

The invention relates to a novel arrange- IO ment and combination of parts whereby the same machine can be used, according to requirements, either as a divider in the same way as an ordinary guillotine-machineor as a trimming-machine, whereby edges alone are cut.

My invention is represented in the accompanying drawings, in which- Figure 1 is a front view, Fig. 2 a side view, Fig. 3 a back view, and Fig. 4 a plan view, 20 of my improved machine. Fig. 5 is a sectional elevation of parts shown at Fig. Fig. 6 is a vertical longitudinal section as seen from the right-hand side of the machine. Fig. 7 is a vertical longitudinal section as seen from the left-hand side of the machine. Figs. 8 and 9 are similar views to Figs. 6 and 7, but showing the parts in different positions. Figs. 10 and 11 are similar views to Figs. 8 and 9, showing the platen and cutter down. Fig. 12 is a sectional elevation of the cut varying cam, indicators, and ratchet driving-gear. Fig. 13 is an end view of Fig. 12 without the pawl-lever, and Fig. 14 is an elevation of the pawl-lever separately. Fig. 15 is a rear view, and Fig. 16 is a.crosssection, of parts drawn to a larger scale than the other figures. Fig. 17 is a cross-section showing the sliding table and its support-ingguides. Fig. 18 is a sectional front elevation, and Fig. 19. is a plan, partly in section, showing the platen and knife and operatingslides. Fig. 20 is a sectional end view of the knife-bar, showing one of its operating-slides. Figs. 21 and 22 are sectional views showing 5 one of the small adjustable stops or gages.-

Fig. 23 is a vertical transverse section of the platen. Fig. 2a is a detail front View of the movable stop. Figs. 1, 2, 3, 4, 6, and 7 show the machine arranged to be used as a divider,

and Figs. 8, 9, 10, andll show it arranged to be used as a trimmer.

a (I are two side frames, and a is an end upright for supporting the bed or table 1) of the machine. a is an upright for supporting the rear end of the driving-shaft c, and a is a cross-bar connecting the upper ends of the side frames a a.

d is the knife-bar, which is mounted in slots in the upper parts of slides d, which carry vertically a fixed bar 61*, extending crosswise of the machine to enable the knife-bar cl to move endwise thereon. These slides d work in guides formed in the side frames a a, and give the ascending and descending motion to the knife-bar dby means of crank-pins 6, carried by cranks fixed on the cross-shaft e and passing through blocks (2 sliding in transverse slots (1 formed in the lower parts of the slides d.

Motion is communicated from the drivingshaft 0 to the shaft 6 in the following manner.

A worm o, fixed on the shaft 0, gives motion through a worm-wheel f to the shaft f,

and this latter, by a toothed wheel f thereon gearing into a toothed wheel 6 fixed 'on the shaft 6, gives motion to this latter.

g is the platen, which is moved up and down in grooves (i provided in the upper part of the side frames a, by means of blocks d on the knife-bar, fitting into inclined slots g in the platen, the action of which is such that as the knife-bar d descends the blocks (1 will press the platen g down onto the pile of paper to be out. Then, as the knife cuts into the pile of paper, leaving the platen behind, the blocks 62 will, by moving in the inclined slots g, give an endwise motion to the knif'ebar d and produce a draw-cut. In the ascending motion a spring'd fixed at one end to the knife-bar d and at the other to a fitting cl, carried by one of the slides d, pulls the knifebar (1 back endwise into position for a fresh out.

o are the driving-pulleys, and o is a flywheel.

h is a traveling gage or stop at the back of the knife. It is formed to travel in inclined gage h to its lowest and most forward position. The distance of the gage h to the rear of the knife at the time when it is in its most forward position is regulated by the cut-varying cam, which is constructed and operated in the following manner.

The body of such cut-varying cam consists of a cylinder 1', mounted on a stud t", fixed in one of the side frames a. It is provided around its periphery with six adjustable studs t the distance of which from the surface of the cylinder c' can be arranged to suit the amount to be trimmed off the different edges of the work. These studs 1' act in connection with an arm 7L fixed on the shaft h, by which the extent of rotation of said shaft, and consequently the forward position of the gage 72-, is regulated to the extent required. The cam-cylinder i is in position to be seen by the operative, and it is provided with indicating-tablets '21 each having the word head, 'tail, or fore edge applied thereto to indicate what kind of out can next be taken.

The cam-cylinder 1' has fixed on its end a ratchet-wheel 11 and mounted loosely on its axis is a pawl-lever z'flwhich is connected by link 2' to a lever 1 mounted on an axis i This lever is acted upon by a cam '5 on the shaft 6 to raise it and thereby to give a partial rotation to the cam-cylinder i, and the weight of said lever and parts connected therewith serves to keep it in contact with the cam 2' A movable stop or support '6 is mounted on an axis i on the side frame a, adjacent to the lever 2 so that when required it may be turned away free from the lever W, in which case the latter will. be allowed to follow the surface of the cam a" while, when the said stop or support 6 is turned so that the ledge i is under said lever, the latter is prevented from descending below a certain point,whereby it is acted upon by the cam 2' during only a portion of its revolution. By these means the pawl is caused to drive the ratchet-wheel i and cut-varying cam 'i a greater or less distance according as the different parts of the latter are required to be brought successively or at intervals into action.

When the machine is to be used for dividing, the lever 2' is raised out of reach of the cam 2' and held in such position by resting on the ledge 6 of the stop or support i An arm h on the shaft h is acted upon by an inclined projection or cam h fixed on the knife-bar (1, so that when the platen g has descended onto the work the said projection or cam 71 shall, by depressing the arm 72 gradually move the gage h rearward as the knife is cutting through the paper.

When the machine is to be used as a divider, the traveling gage h is raised out of action in the position shown at Figs. 2, 3, 4L, 6, and '7 and held in such position by means of a bolt or stop h acting in connection with a slot or hole in the disk 77, fixed on the shaft h and by withdrawing such bolt or stop 7L the gage h can again be thrown into act-ion.

The platen g has a movable portion g which is to be used as an adjusting-gage to facilitate the placing of the paper on the machine in its correct position for dividing. This part 9 is normally kept in its raised position, that is, in a line with the bottom face of the platen, by a spring 9 but which can be depressed by means of the knob g, as shown in dotted lines in Figs. 1 and 8, and thus enable the pile of paper to be placed at once into the required position without having to move the knife-bar.

I also provide the rear part of the machine with an extended sliding table j, mounted on V-guides j, to support the sheets of paper .to be divided, and, in connection with such extended table j, I use atraveling gage 75, which can be set by means of the screw 7a to any required position, and it iscaused to move away automatically from the edge of the paper as the latter is being divided in order to afford room for the movement of the paper as it is forced forward by the beveled face of the knife and to return to its true position for gaging a fresh out. For this purpose the screw 71; works in a nut 76 fixed to the gage 7c, and its two ends are mounted in bearings k with capability of moving a certain distance endwise therein. The screw-shaft also passes through a sliding block 70 mounted in guides fixed to the under side of the bed or table I), but is prevented moving in rela tion thereto by collars 70 This block 70 is, by a fork-ended link 7a, connected to a lever 70 fixed on a shaft 7.0 and it has pin-jointed near the center thereof aslotted arm 7c, fitting and guided by the shaft e and provided with antifriction-wheels 70 bearing against opposite edges of the cam 7a By these means the gage 713 is moved into and out of its gaging position and is retained for a certain time at its foremost and rearward positions. The screw 7t" is rotated by a small hand-Wheel on the front end thereof.

The gage 70 can be thrown out of action when it is required to use the machine as a trimmer by separating the forked end of the link 70 from the pin at the upper end of the lever 70 as shown at Figs. 8 and 10, when the said lever can move without imparting motion to the screw 70 and gage 7c.

The sliding tablej is capable of being placed in contact with the rear edge of the fixed table b, as shown at Figs. 2, 4, 6, and 7, to form a convenient support for the paper to be divided and of being placed at a distance therefrom, as shown at Figs. 8, 9, 10, and 11, when the machine is to be used for trimming edges, and a bolt 7' is employed, as shown at Fig. 4, for locking such table in either its forward or rearward positions.

I also employ a simple arrangement of parts whereby the clutch Z for throwing the machine into and out of action can be thrown out of gear automatically after each out, can be kept continuously in gear, and can be thrown out of gear, when desired, by the foot. For this purpose the clutch-rod Z has a pin Z acted upon by a rotating arm or wiper Z fixed on the shaft f, to throw the machine automatically out of gear after each cut. This rod Z has a pin Z, passing through a vertical slot in the upper end of a lever Z fixed on the treadle-shaft which is capable of being operated by the treadle Z at any desired time to throw the machine out of action, and such rodl has a longitudinal slot at its front end through which passes a pin at the rear end of a lever Z by depressing the outer end of which the pin Z is raised above the reach of the wiper Z and the machine set in action at any desired time, and by the aid of this lever Z and a locking-pin Z the machine can be kept continuously running until such locking-pin is removed or the treadle Z is depressed. A spring Z around the clutch-rod 1 acts to force the latter rearward and to place the two parts of the clutch Z in gear with each other when the said rod is not pulled forward by the wiper Z or treadle F.

It will be understood from the foregoing that when the machine is to be used for trimming the gage h and parts acting therewith will, as shown at Figs. 8, 9, 10, 11, 15, and 16, be in position for use, while the table j is in its rearward position and the gage 7i; and screw 70 disconnected from their operatinglever 70 by disconnecting the link it from the upper end of said lever, and that when the machine is to be used as a divider the gage h and parts acting therewith will, as shown at Figs. 1 to 7, be out of action, while the table j is in its forward position and the gage 7c and screw 70 connected with their operating-lever 70 by means of the link k.

The gage 70 has connected thereto a gagebar 71: which slides in a groove in the table I) and acts in connection with divisions on the sides of the groove to regulate the position cf said gage. By constructing the gage 7c and parts connected therewith so as to enable it to be set near to the knife it may be used both when trimming and dividing paper.

on m are gages working in slots in the table Z) and adjustable by means of screws 9%, working in tapped lugs m fixed to such gages, the said screws being capable of rotation by means of disks m on the ends thereof.
