To aZZ whom it may concern.-

Be it known that LFREDRIOK W. COOPER, of Danbnry, county of Fairfield, and State of Connecticut, have invented a certain new and useful Improvement in Machines for Attaching Sweat Leathers and Bands to Hats, of which the following is a specification.

This invention relates to machines for attaching sweat leathers and bands to hats, by means of wire staples which are automatically formed in the machine, and it consists in the construction and novel arrangement of parts, as hereinafter set forth.

I will describe a machine embodying my invention, and then point out the novelfeatures in claims.

In the accompanying drawings, Figure 1 is a front elevation of a machine embodying my improvement. Fig. 2 is a side elevation thereof. Fig. 3 is a plan view below theline 3, 3 of Fig. 2. Figs. 4, 5 and 6 show certain cam mechanism on an enlarged scale. Fig. 7 is an edge view of a cam yoke. Fig. 8 is a top view of the upper portion of the machine showing, among other things a number of cross-bars or cross-heads which connect pairs of rods and thereby transmit motion produced upon one of the cross heads of each pair by a cam.

resented in Fig. 10, but being a rear view,

it of course represents them from the re- Fig. 15 is an enlarged view of a feeding mechanism employed. Fig. 16 is an enlarged plan view of a clinching head employed. Fig. 17 is a vertical section taken parallel with a tang markedf in Fig. 14. Fig. 18 is a horizontal section taken on the plane of the dotted line 18-18, in Fig. 17. Fig. 19 is a perspective View, showing detached from one another, various parts composing a block marked F in Fig. 14.

Referring byletter to the drawings, A designates the main frame of the machine, having at the top forwardly extending arms a, and a Web portion or side wall at extending, as here shown, from the lower end to the lower arm a. A main shaft A has a bearing through the rear portion of the frame A and also in a bracket A attached to the frame A. A power wheel A is mounted on the shaft A. A shaft A for operating certain mechanism hereinafter described, is driven from the main shaft A, but as it is required to stop the rotation of the shaft A at certain inter vals, while the shaft A is rotating, I provide a clutch mechanism between the two shafts, consisting of the section B rigidly attached to the shaft A, the section B rigidly attached to the shaft A and the section B movable longitudinally on the shaft A and provided with a pin b, movable through a hole b in the section B into an are shaped slot 1) in the section B. This slot 1) increases in depth from its entrance end to a shoulder or abutment b at its opposite end. The movable section 13 is chambered at its end as at b to receive the hub like portion 5 of the section B. A spring B surrounds the shaft A between the clutch section B and a collar 12 adjustably secured to the shaft A by means of a set screw. This spring serves to, move the section B longitudinally of the shaft A to engage the pin b with the section B. The pin 17 is moved out of engagement with the section B by means hereinafter described. It will be observed that the one end of the shaft A projects into the hollow end of the shaft A so that the shaft A forms a bearing for one end of the shaft A The section B is not only a section of the clutch mechanism, but is an eccentric for vertically reciprocating an eccentric rod B which is guided by a stud or screw 1) extending through a slot in the rod B into the Web a The lower end of the co centric rod B bears upon or engages with a rock lever l3 fulcrnmed at about its center to a downwardly extending portion C of a bracket 13*, and extending underneath an anvil B movable by said rock lever vertically through a hole in a forwardly extending portion of the bracket B. The eccentric rod B is adjustable longitudinally to accommodate it to the adjustment of the bracket B and as a means for such adjustment I provide it. with a screw bolt b inserted in a tapped hole in the end of the rod, and I employ a check nut on the screw bolt as shown, to hold it as adjusted. The lower portion of the hole in the bracket B through which the anvil 13 passes is enlarged to form a shoulder at its upper end and the anvil is provided with a shoulder 19 A spring b surrounds the anvil between the shoulder b and the shoulder 19 and serves to return the anvil to its downward position. The bracket 13 is rendered adj ustable vertically to accommodate the machine to the thickness of a hat material to which'a sweat band is to be applied, and as a means therefor the vertical portion 0 is movable in a guide way formed by flanges G projecting from the frame A, and a front plate 0 secured by screws or otherwise to the flanges O. The plate 0 is slotted or forked at its upper end and the frame A is provided with a vertical slot 0 so that the bracket B and rock lever 113 may be moved down out of the way when desired, and also to manipulate the finer adjustments of the bracket, which may be done by the following means. A bolt 0 has its upper screw threaded portion 0 engaged in a tapped hole 0 in the end of the portion Got the bracket and a jam nut c is engaged with the threaded end 0 beneath the end of the portion 0. The lower-portion of the bolt 0 is movable through an opening in a plate 0 extendingfrom the frame A and this lower portion is screw threaded and provided with jam nuts 0 A red C screw threaded at its upper end engages in a tapped hole in the bolt 0 and has its lower end engaging with a foot lever, not shown. Obviously the bracket may be lowered so that the nut 0 will appear between the lower ends of the flanges C and the top of the plate 0 The jam nut 0 may then be adjusted by any suitable tool so that the screw thread 0 may be turned in the tapped hole 0 in any desired direction. At this time the jam nuts 0 must also be adjusted. After the required adjustment as described, the bracket is forced upward by means of the foot lever, and a wiper arm 0, pivoted to the plate 0 is moved beneath the shoulder formed by an annular channel 0 in the bolt 0 as plainly shown in Fig. 1. This wiper arm 0 is provided with a suitable handle 0 so that it can be moved by hand.

Having so far described the machine, I will now describe the mechanism for feeding and cuttipg the wire, forming a staple and inserting itf D designates a spool or reel of wire mounted at one end on a fixed center at on a frame D secured to the upper arm a of the frame and at the other end on an adjustable center 0t movable in said frame and held as adjusted by means ofa thumb screw 01 From the spool or reel the wire d extends through anveye d in aguide arm D affixed to the machine frame, and also through a guide 61 secured to the front plate D to feed rollers d d The feed rollers d d have journal bearings in the plate D and in a bracket arm D attached to said plate D The feed roller d is provided with a gear at meshing with a geard on the feed roller (1 and this gear d engages with a larger gear 61 having journal hearings in the plate D and bracket D The gear wheel d vhas affixed to it aratchet wheel (Z with which engages a spring controlled dog d pivot'ed to an arm E which is fulcrumed on the journal of the gear al To the outer end of the arm E a link-E is pivoted. The opposite end of the link E is pivoted to alever E fulcrumed on a screw engaged with the plate D and the opposite end of the lever E has a sliding pivotal connection with a lever E also pivoted on a screw engaging with the plate D The free end of the lever E is projected between lugs e carried by a vertically reciprocating bar F. The lugs eare preferably adjustable on the bar F and I have therefore shown them as slotted longitudinally and held in position by screws passing through the slots into tapped holes in the bar F. The advantage of making these lugs adjustable is to vary the feed. Obviously, when the lugs are adjusted as close together as possible, lost motion between them and the lever E will be avoided, and hence the maximum feed will be obtained. By adjusting the lugsfartherapart, more or less lost motion will be secured,and aconsequent variation of the feed will be obtained. By the construction just described it is obvious 'that by the upward movement of the bar F the feed rollers will be operated to move a sufficient length of wire into the machine to form a staple. From the feed rollers d d the end of the wire-is forced through an openingfin a block F having a plate or tang f through which screws are passed to secure the block to the plate D The block F consists of several pieces, that is, it is made up of a back plate f from which the tang f extends, intermediate plates f f and the outer'platef The plates f f f are secured to the plate f by means of screws. The opening f for the passage of the wire communicates laterally with a groove j, which is substantially V shaped in cross section. The plate f on its inner side is provided with a rib f adapted to fit into the groove f At the rear end of the openingf is a regulating screw f which may be adjusted to regulate the length of wire required to form a staple. Of course, when the screw f is adjusted the. blocks 6 must be adjusted correspondingly. After a wire is fed into the machine as described the proper length to form a staple is cutoff by means of a vertically reciprocating cutter G, movable in a slot 9 in the plate f and coacting with a fixed cutter G in the bottom of said slot. The cutter G may be adjusted vertically to bring its cutting edge substantially flush with the lower side of the wire opening f and held adjusted by means of a set screw 9'. The cutter Gis carried by a bar G reciprocated vertically by the shaft A through cam mechanism as will be hereinafter described. After the length of wire shall have been cut it is bent in staple form by means of a bender H carried by a.

rock lever H fulcrumed at h on the block F and having a link connection h with a plunger rod H The bender H is movable across and considerably above the wire openingf in aslot 71 formed-in the block F. The bender has a yielding connection with the rock lever H, and as a means therefor I attach it to or form it integral with a slide block 72 This slide block 71 is movable in guide ways It formed in the lever H and is held in position by means of a pin h5 on the lever extending into a slot in the slide block. A spring h interposed between a portion of the block H and the lever H serves to hold the cam or curved surfaces 77/7 of the block against the surface of the plate f The bender H will engage the piece of wire at about its center and by a continued upward movement the ends of the wire will be drawn out of the openingfand the said wire will be formed in staple shape. After the bender shall have resumed its normal position a driver H carried by the rod F moves through a vertical hole 7&9 in the block F and serves to force the staple out of the slot 77. and through the hat material and the sweat band.

Before describing the means for turning or clinching the ends of the staples, I will describe the connections between the shaft A and the parts F, G2 and H whereby said parts are reciprocated. I is a cam secured to the shaft A and coacting with a cam yoke I, having its grooved edges engaging with ribsz' secured to or formed integral with the inner surface of cheek pieces t secured by screws or bolts to the opposite sides of the arms a. From the yoke 1' a stud 1 extends upward through an opening in the upper arm a and from this stud I a cross-head 1 extends to and engages with the cutter bar G J is a cam mounted on the shaft A and coacting with a cam yoke J having edge grooves to engage ribs 2' on the cheek pieces t". From this cam yoke a'stud J extends upward through an opening in the upper arm a and a cross-head J connects this stud with the rod H K is a cam mounted on the shaft A and coacting with a cam yoke K having edge grooves engaging ribs *6 on the cheek pieces i. From this cam yoke a stud K extends through the upper arm a and a cross-head K connects this red with the bar F. The studs 1 J and K are threaded at their upper ends, where they receive the cross-heads, and jam nuts are provided as shown, to secure the cross heads at any elevation it may be found necessary to adjust them. Each cam I, J, K, has a plate is secured to one side. These plates have their greatest length transverse to the length of the cams and the ends thereof bearing at certain times against the surface of the top bars of the respective yokes serve to steady the cams. These cams I, J K are suitably shaped to operate their respective parts at the proper time. t

I will now describe the manner of turning or clinching the staple ends. L designates a clinching head arranged beneath the opening 71 and provided in its upper surface with oppositely extending grooves Z, the bottoms of which incline upward from the adjacent ends. The clinching head is mounted on a resilient arm L which is adjustable longitudinally and laterally so as to align the grooves l with the ends of the staple. The arm L extends from a block L resting on the upper surface of the bracket B between side lugs Z and forward of an end lug Z Screws Z extending through the lugs Z and impinging against the sides of the block L serve to adjust the arm L laterally and a screw Z extending through the lug 1 serves to adjust the arm longitudinally. A bolt L serves to clamp the arm rigidly in position. The hole in the block L through which the bolt L passes is larger than the bolt so that the several adjustments may be made. After the several staples shall have been inserted in a hat the operation of the shaft A must stop, otherwise the machine would continue forming staples after removal of the hat, as the shaft A is in constant rotation.

As a means of disengaging the clutch section 13 from the clutch section B and holding it out of engagement, I employ a lever N fulcrumed intermediate of its ends to a box like structure N secured to the web a. The upper end of the lever N has a pin n projected into a cam slot n'in the clutch section B A latch N is movable into the line of 0s cillation of the lower end of the lever N and when in its upper position the lower end of the lever N will strike against the latch which will thus prevent further oscillation and the cam surfaces or side walls of the annular slot 77/ impinging against the pin n will cause the clutch section B to move longitudinally of the shaft A and out of engagement with the section B. As a further means for prevent ing the shaft A from rotating beyond a certain limit, I employ a yielding stud N having a taper upper end over which a U shaped notch n in the clutch section B engages when the said section is moved longitudinally as described. This stud N 3 extends into a hole in the structure N and a spring a is interposed between the lower end of the stud and the bottom of the hole. The latch N is secured to and extends outward from asliding bolt N movable vertically in a way formed in the structure N and havinga rod connecfoot lever to move the latch N downward and allow the clutch sections to engage. It is to be understood that before starting the machine, a hat is in position, with the sweat leather and band in place, between the lower end of the block F and the clinching head L. The rotation of the shaft A will now cause the cutting, forming and insertion of the staple through the material, as before described, at the instant the staple ends come in contact with the clinching head the anvil B contacts with the arm Lbeneath the head L and supports the same until the ends of a staple are clinched. After inserting one sta ple the hat is turned by the operator to a position to receive another staple and the operation is continued until a sufficient num:

her, say six or seven, staples shall have been inserted. Then of course the latch N is allowed to assume its upper position to stop the machine.

It will be observed that this machine forms and inserts the staples lengthwise of the circumference of the hat.

The essentials of the machine are a feeding mechanism for a wire, a cutting mechanism for severing pieces of wire of the proper length to form staples, a bending mechanism for forming severed pieces of wire into staples, one at a time, a driving mechanism for driving a staple through parts to be connected by it, and a clinching mechanism; each of these mechanisms in my machine, being wholly independent of the others, in the sense that it does not derive motion through any of the others, but takes all its motion from its own cam mounted upon the driving shaft. This is extremely advantageous because it enables me to provide for adjustments in the difierent mechanisms, so as to make all these mechanisms operate in the proper relation to each other.
