IMPROVEMENT IN MACHINES FOR MAKING FLY-NETS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whomit may concern. I

Be it known that I, A. PRUTZMANN, of Canton, in

the county of Stark,'al 1d State ofOhio, have invented certain ncwand useful Improvementsin Machines for .Making'Fly-Nets; and I do hereby-declare that the following is-a full, clear, and exact description of my invention, reference beinghad to the accompanying drawings, forming a partof this specification, and to theletters'of reference marked thereon, of which drawings Figure 1 is a plan of my improved machine.

. My invention relates to certain improvements in the construction of machinery for making fly-fnets, said improvements consisting in the novel construction of mechanism for cutting scraps of leather which can be rounded into a circular ibrnninto strips suitable for mechanism for blacking the small straps; these-several improvements affording the manufacturer mechanical facilities for pertbrming all the operations required in making fly-nets, thus greatly diminishing the cost andlabor of'making the same.

To enable others skilled in the art to make and use ,my invention, I will proceed to describe its construction and operation.

Thebase of my machine'consists ot a plate, A,- of

iron or other suitable materiahiu the sides of which are cut slots a a, in which are bolted various parts of the machine, as hereafter shown.

The face-plate G is secured at one edge of'the plate A, and serves, together with a plate at each end, to

support the bed-plate B..

The guide-plate T is made with a flange atits front edge, and is secured. on the bed-plate B by the screw V, which passes through a raised washer on the plate T, down through a hole in said plate, and through a slot in the plate B, into a bevelled nut under the plate B, which bevelled nut fits in the slot in the plate B,.which is also bevelled, thus preventing the nut from turning.

In the plate T is fixed the standard 2, the upper end of which is formed .with an eye, through which passes a tension-bolt, with a thumb-nut, Z. v

The arm U is pivoted, by a bolt, 1, to the lower end of the standard 2, and the spiral spring 3 connects the end of the arm U with the tension-bolt on which is the thumb-nut Z.

The front end of the arm U extends through a slot in the flange of the plate "1, and the roller a is pivoted on it, as shown in figs. 1. and 5. I

The arm W has a slot cut in its rear end, through which passes the screw w, by which it is secured to the plate T; and the front end of this arm extends through a slot in the flange of the plate '1, and is provided with a thumb-screw, w.

The arm S is also secured to the plate T, on the other side ofthe arm U, by a screw, t, passing through a slot in its rear end, and extends through a slot in the flange ofthe plate '1, and is provided with a thumb-screw, 'r, and has a'shonlder formed 0n-its underside, a little distance back of the-screw 'v.

The slide-rails Z pass through holes-in the plate. (L -and are fastened by a clamp on the under side of the-plate B. p

The slide h encircles the rails Z, and on it is pivoted the arm t, the front endof which is provided with the centre-pin It, andthe rear end of which is flattened out and bent down against the rail Z, against which it is pressed by the springj, which is fastened in the slide 7:, and has its other end pressing against the other rail Z, as shOwn iufig. 1.

The knife in (see fig. 1) extends up through a slot in the plate B, and is held against a block on the under side of said plate by a bolt, 4}, which screws through a nut on the under side. of the plate B.

The knife 00 can be made in an ordinary knife-form,

scribed, can be used, by which the leather could be partially trimmed to around section as it was cut off.

The strap-trimmer M7 is composed of the standard M, which is secured by a bolt in a slot, a, in the plate A, and has the cross-bar l 1 at its head, to which the upper end of the guide-bar 6 6 is secured, the lower end of said guide-bar being secured to the standard M, as shown in figs. 2.

The trimming-cutter 7 is made with one or more holes, 8 8, to suit difierent sizes of straps, and is of the cross-section shown in detached view in figs. 2, the V-shaped end being ground sharp around the holes 8 8, and forming around said holes a cutting-edge, which trims the corners from the square strap as itcomes to the cutter through a slot in the guide-bar 6 6.

The lower end of the cutter 7 is made pointed, and fits in a hole in the standard M, and its upper end is formed into a bolt, on which is the jam-nut 9, so that by putting the bolt-end of the cutter 7 into the slot 10, in the cross-bar 1 l, and turning up the nut '9, the cutter is firmly fixed in the standard.

Two or more standards, M, with trimming-cutters 7 could be used in succession on the plate A, if found desirable, each taking off a portion of the corners of the strap, and thus gradually reducipg it to a round section.

The bnrnisher 12 is fixed in the standard L, on the plate A, and has formed in it one or moreholes, 1.3, of sizes corresponding to the required size of strap.

' Itis fastened in the standard L by means of one pointed end fitting in a hole in one arm ofsaid standard, while the other threaded end fits in a slot, 15, in the other arrn, (see fig. 1,) andis held by a jam-nut, 14, as shown'.

In order to insure the strap being drawn correctly through the holes 13, in the burnisher 12, or through the holes 8 of the trimming-cutter 7, in case the burnisher 12 be not used, the standard K is attached to the plate A, and has the grooved wheel 16 journaled in a slot at its upper end, in such a position as that its lower face shall be in line with a hole, 13 or 8, through which the strap is to pass, or in line with each of said holes, which are in line with each other, when both burnishcr and trimming-cutter are used.

The vise-drawiug-cylinder standard J is bolted to the plate A, and has a head through which passes the shaft 20, having a crank, 19 19, at one or both ends, as found-desirable.

The vise-cylinder I consists of the jaw I, of a cylindrical form, and of somewhat less circular length than the semi-circumference of the cylinder, and having a circular head at one end, which is fixed to the shaft 20.

The other jaw, 17, is of the same form, but its head is loose on the shaft 20, and is provided with a screw,

18, which works in a nut in said head, and has the cone-shaped wedge 22 at its lower end.

The incline 23 is-secured on the jaw 17 and the incline 24 on the jaw 1', from which it is readily seen, that by advancing the wedge 22, by means of screw 18, the sides of the jaws I, 17, shown in fig. 7, will be caused to separate and that the other edges of said jaws will consequentlyapproach each other, and grasp the ends of the straps, introduced between them, like a vise, and that when so grasped, the strap can be drawn out and wound on the cylinder 1, by turning the cranks 19 or their equivalents.

The lip 21, on the jaw I, works in a slot in the head of the jaw 17, and thus prevents the jaws from separating further than would be desirable, as shown in fig. 5.

The cutter-box N (see figs. (S) is of the general form shown, and has an arm, 65, at one side, by which it is secured by a bolt, 64, to one ofthe upright pieces under the bed-plate B, as shown in fig. l.

- The cuttenbase 32 is secured near the centre of'the box N, and on it are secured one or more cutters, 5 5, by means of the clamp 34 and screw 4.

,the strap to be' to the back plate, under the bedthe other ends of which The cutters 5 are made with grooves in their lower faces, and have their front ends sharpened, so as to present theappearance shown in plan and side elevation in figs. 1 and 6.

The cells 33 are arranged in the box N, under the cutters 5, and the corrugated rod 6, of a square section, is slid into these cells 33, together with the end of pointed, which rests on the rod 6, when, by turning the rod 6 upward until the strap is brought between the cutter 5 and rod 6, and then drawing the strap and rod back, keeping the rod 6 pressed against the cutter 5, as shown in fig. b, it is evident that the strap will be properly pointed.

The frame-piece Y is secured at one end by a bolt plate 13, and its other end is attached to the double plate 40,'whioh is attached to the ends of the inclined plates 54, 54,'(see fig. 11,) which are fastened to the plate 0.

A guide-bar, n, is fastened, by a bolt, in aslot in the frame-piece Y, so that by loosening the bolt, it may be moved along said piece to any desired point.

The bolts q q project through holes in the piece Y, and are held byjam-nuts 1) p, as shown in fig. 1.

The heads 1 are fastened on the ends of the boltg, and in these heads are fastened the tension-rods 'r r, slide through'holes in the compound revolving nuts Z m, which are secured in theplate O, as shown in fig. 1

The straight-cutting knife-shaft 60 is of the form shown in fig. 14, and has a central slot, in which are arranged the knives 61 61, which are maintained at the proper distances apart by the blocks 62 62, which are headed at the ends, as shown in detached view, to prevent any danger of their working up or down in the slot in the shaft 60.

The end block 63 is made longer than the others, so as to act as a gauge to the leather, and the several blocks and knives are firmly secured in the shaft 60, by the clampingscrcw 37, shown.

The shaft 60 is supported between the plates G and 40 by the journals 67 67, one of which fits in a box in the plate 0, and the other projects through a box in the plate 40, and has the handle 36 seclued by a setscrew, 45, on its end.

The knife-pressure roller-shaft slots in the plates 0 and 40, and which slides in said slots, ends of the shaft 56. I

On this shaft are arranged the rollers 59 59, which are of a width equal to that of the strap to be cut, and which have a collar on one end to keep them a little apart, so as to let the knives 61 61 set up between them, when found desirable, or, if preferred, these rollers 59 can be cut out of leather, and be allowed to set up against each other, in which case, the knives 61 would cut into instead of between them.

The end roller 58 is niade larger than the others, so as to act as a gauge to the leather while being drawn through.

The presser-bar door X is of the form shown in figs. 8, and has the journals 46 46, and the back-piece 48, in which are arranged the set-screws 50 50, which press against the plate 49, and thus hold the presserbar 47 in position.

This bar 47 is of wood 56 is arranged in has the yoke 57, with its ends resting on the lead, or any soft metal, and is so arranged as that the knives 61 just cut its lower edge when turned up, as shown in fig. 11.

The door X is held, by its journals 4G 46, in the plates (J and 40, and is held down, eitl er by slotting the holes 41, in the plates 40 and in which the journals 46 work, and having the hooks 53 to hook into slots 55 (see fig. 1) in the plates 0 and 40, by pushing the door X forward when turned down, or by having a retaining-bar,43, arranged in slots 42, in the plates 0 and 40, to slide under the rear flange 51 of the door.

i forcing down inthe slot in'the'plate B.

Thesc rews 35 35, in the doorX, press on the. yoke 57, which presses down theknife-rollers 59 59 and the handle 36, of the knife-shaft 60, has a slot, 44, cut in it, in which the adjustable piece 38 maybe introduced,

by loosening the screw 39 which binds it to the plate a a 40, when, by adinsting the piece 38 and tightening the screw 39, the movement of the handle 36 and shaft 60 may lie-limited as desired, in order to prevent the knives 61 from cutting too deeply into or between the rollers 59.,

The punch-standard 0 is bolted to the bed-plate B,

and has the lever, Q pivoted to i-t by a bolt, 0. (See figs. 1 and 5.), h

The punch-slide P is attached, by a bolt, 11,- which passes through a vertical slot in the standard 0, to the lever Q, and a guide-bolt, g, is also fixed in the slide 13am extendsthrough the slot in the standard 0 and serves to steady the movement of said slide.

' The rod f is fixed infthe slide 1, and extends up through a flange on the side of the standard 0, where it is provided with a thumb and clamp-nut, f. i

The slot'c is cut in the horizontal arm of the sli d I P, and in it-are secured one ormore punches, 1), pro

vided with thread and nut at their upper ends; and made of atapering form, with a cutting-edge, as shown I in fig. 5. a

A slot is made in the plate 13, through which the punches I) pass in punching the holes in the leather, and, if desired, a plate of leather or soft metal can be laid on the plate B, nnderthe punches b, for them to punch through,in order to prevent "the strap from The gauge R is held by the clamp and screw Son the plate B, and serves as a guide in punching thel v l holes in the strap.. x

The blacking-cup G H consists (if the cup H, which is bolted on theplate A, and has the cover G hinged "toit', asshown.

. The edge of the cover G is bent up so as to form an entrance-aperture, 26, and an arm, 31, is. fixedin the cover G, and extends down nearlyto the bottom of the cup, where it is provided with an eye-, 'with aliuing of leather if desired. a

l A clamp, 29, is fastened to the arm 31 at the cover G, and a screw, 27, passes through 'the cover G into said clamp, by means of which the wiping-leather30 is held in position below the exit aperture 28 in the cover G; said cover G being held down by the screw 25, as

shownin figs. 1 aud t. p p p The reel-standard 1) is bolted to the plate A, and has a head, in which the reel-shaft F works; one end ofsaidshatt having acrank, and the other endhaving the reel E attached, as shown in figs. 1 and 5.

Where a small round strapis to be formed from a square strap of weak leather, along, thin trimmingcutter is required, and for this purpose, the trimmer shown in figs. 2 is used.

This consists of'a standard, M, which is bolted in the plate A, in place of the standard shown in 1,.and on the face of which is secured the retaining-plate 71,

as shown; p h h p The cutter 7 O is.of the tapering form shown, and

, hasa long, thin section, as shown; the hole 80 in said that hy loosening the bolt 72, the plate 71 may be i turned around said bolt as an axis, away from the standard M, when the cutter 7 0;niay he removed and replaced by another cutter, with a different size of hole, 80, if desired. a

the cutter 70 will he firmly heldiu position, but.

Where scraps of leather are to be cut'into small made with a tapering point, is secured in the slot 83,

by means of the screw 82, which bears against ablock, 8b, which. rests on the knife, as shown.

In using this device, one leg of a common pair of compasses is secured between the knife 85 and plate 86, and the knife is set so as to projectbeloiv the wheel 84, (which runs on the leather,) adistance equal.

to the thickness of the leather.

, The other leg ofthe compasses is then set in the centre of the scrap, and the other leg is so adjusted as to bring the knife 85 into the circumference of the circle to which the scrap'isto bereduced, when, by pressing down on the block 81 and turning the compasses, the scrap will be out out, as desired.

. Having thus fully described the construction of my improved machine, its operation will be easily understood from the following description 2' g a When a scrap of leather is to be out into straps, it

is first trimmed into a circular form, by means of a The starting-piece is then passed between the' plate T and knife x, under the roller -u, thence through a hole, 8, in the trimmer 7, and a hole, 13, in the bur nisher 12, under the grooved wheel 16, to the visecylinder 1, into which it isclamped, when, by turning round form by the cutter 7, and is further reduced and pressed bythe burnisher 12, and, finally, is wound up on the cylinder I. h

As the last of the strap is cut,'aud after it has all passed through the burnisher 12-or cutter 7, if no burnisher is used-the end is taken to the box N,

and is pointed, after which it is passed through the eye in the arm 31, in the blackiug-cup cover G, and

through the hole in the wiping-leather 30, and out of,

the hole 28, and is attached to-the reel E, when, by

filling the cup H with blacking, asteuing down the cover G by the bolt 25, and turning the crank F, the strap is unwound from the cylinder I, blacked, and wound on to the reel E, as is readily seen. 'To cut the straps of leatherfi'om 'a long strip'of leather, the guide a is first fixed on the piece Y, ata distance from the plate 0 equal to the widthof the strip to be cut. a v The heads -rare then set at the samedistance from the plate 0, by turning the jam-nuts p; the knives til are adjusted at the required distances for cutting the desired width of strap, by the introduction of suitable blocks, 62, (the distance between the guide-block 63 and plate being the same as that between said. plate and the heads 1 and guide 72,) and the rollers 59 and guide-roller 58 are arranged to correspond with the knives 61 and block 63.

The strip to be cut is then introduced into the slot in the piece Y, between the plate 0 and guide 21, and passes over one tension'rod, a, under the next, over the next, said rods being turned so as to give such 'an amount of tension on the leather as will serve to keep it drawn straight and smooth.

The handle 36 being turned up, as shown in fig. 5,

- throws the points of the knives 61 down, so that the strip can be passed in between the presser-bar 47 and rear inclined plate 54, and between the front plate 54 and the rollers 59.

The screws 35 are then'turned down, so as to bind the rollers 59 down on to the strip of leather, a cord is put through holes in the end of the strip, and its ends are clamped in the vise-cylinder I, which is slid out in front of the cutting-mechanism, when, by turning up the knives 61, by. means of the handle 36, into the position shown in fig. 11, they cut through the strip, which is then drawn forward, by turning the cranks 19, and is cut into straps of the required width, as is readily seen, the bar or plate 47 and rollers 59 keeping the leather pressed down on to the knives 61, so as to insure its being cut.

The straps of leather thus cut out together, and wound on the cylinder I, may be separated from each other, and be rounded, pointed, blacked, and wound on the reel E, by the use of the devices hereinbefore described. 1

The .punches b b are set in the groove or slot 0, in the slide P, at such distances as will cause the holes to he punched at the proper distances from the edge of the strap and from each other, said strap being moved along under the punches, and against the punclvstandard o and the sizes of the holes punched are regulated by turning the nut f up or down on the rod f, which limits the movement of the conical-shaped punches, and, consequently, the sizes of the holes punched, as is readily seen.
