- To all whom it may concern:

Be it known that I, JAMES PHILIP BIRD, a citizen of the United States, residing at Worcester, in the county of Worcester, State of Massachusetts, (post-oflice address Worcester, Massachusetts,) have invented certain new and useful Improvements in Machines for Securing Flies to Boxes, of which the following is a specification.

This invention relates to machines for securing flies to boxes, and is of the kind wherein a continuous strip of paper is gummed, fed onto the box-receiving table, cut into the desired lengths, and secured to the box; and the object of the invention is to simplify the method of securin flies to boxes and obviate the present diffiou ties arising in this class of machines by completing the entire process of gumming, cutting, and pasting with onemachine. tinuous strip of'paper of the Style selected is fed from a roll over a glue-distributing wheel, through an intermittently-operated feed-roll and' feed-wheels, and thence down onto an oscillating box-receiving table, after whichit is cut off and the box-receiving table brought into contact with an intermittently-operated presser-bar when thefly is secured to the box.

The above-recited sequential movements are produced by having the feed-roll intermittently operated by a rack-bar, pinion, ratchet- ,wheel, and intermediate connections and'a series of properly-arranged cams on an auxiliary shaft driven by the main shaft and operating, through intermediate mechanism, the cutting-knife, the oscillating box-receiving table, and the presSer-bar for each complete operation of the machine. Heretofore in this class of machines it has been necessary to previously. prepare the flies before they were placedupon the machine, usually by cutting them intothedesired len ths, gumming,

- and putting them into stac rs or'pads before placing them on the table of the machine.

Each fiy is then dampened, thebox placed in In order to accomplish this, a con,

the box -receiving table, cut OE, and secured to the-box a great saving of time is effected and a uniform condition of the pasted flies is always preserved.

This invention consists of certain new and novel features of construction and operation, which will be fully and clearly set forth in the following specification and the essential points of'merit pointed out in the claims.

In the accompanying drawings, forming a part of the specificatiom Fi'gure 1 is a side elevation of the machine, the parts being shown as ready to receive a box. Fig. 2 is a plan view. Fig. 3 is a partial side elevation with parts of the side frame broken away to show the operating-cams, the position of the parts being the extreme op osite of'that shown in Fig. 1. Fig. 4 is a etail elevation of the rack-bar, pinion, and ratchet-wheel for operating the feed-roll. Fig. 5 is a reverse e evation of a part of the same." Fig 6 shows the feed-roll and one of the feed-wheels. Fig.

section of the cam, driving-gear, and parts for adjusting the throw of the rack-bar. Fig. 10 is a detail view, partially in section, of the "feeding mechanism. Fig. 11 is'a side view of the rack-bar holder, rack, and pinion. Fig. 12 is a detail view of the knife. Fig. 13 is a top plan view of the table 95 and gooseneck 96; and Fig. 14 is a detail end view of the table, the fly-holding plate, and the presser-bar, the parts being open, as shown in- Fig. 1. Similar numerals of reference indicate like parts throughout the specification and the various views of the drawings.

In the practical application and construction of the machine, 1 1 are the side frames supporting the various working parts, the

driving-shaft 2 being journaled therein and.

having on its respective ends the driving-pulley 3 and on the operators side'of the machine 'a pinion 4, meshing with and driving a gearwheel 5, secured to the ,auxiliary shaft 6.-

Bolted to the outer face of the gear-wheel 5 is a block 7, provided with a longitudinal dove-v tailed or beaded groove 8, Fig. 9, adapted to receive and retain a stud 9, having a corresponding dovetailed or beaded head, through which is a threaded opening 10 to receive the adj listing-bolt 1 1, extending along the groove 8 and held in position by caps 12, fastened to. each end of the block. Fitted onthe stud 9 which will move the stud 9 toward or fromthe axis of the gear-wheel to the desired position, when the lock-nuts are tightened and the parts will again be held rigidly together.

A shaft 24 carries the feed-roll 25 and is journaled in bearings 26, bolted to and extending through the side frames, said shaft having a pinion loosely mounted thereon,

engaging the rack 14 on the rack-bar 14. Freely supported on the end of the bearing 26 of shaft 24 between the pinion 30 and the side frame by means of a collar-bearing 29 is a block 27, having a longitudinal groove 28 therein, in which the rack-bar is guided and held in engagement with the pinion as it moves up and down with each revolution of the gear-wheel 5, and has a cut-away portion 31 to permit the rack-bar to mesh with the pinion on shaft 24 and is also free to move in response to the various planes assumed by the rack-bar during its operation. Mounted on the reduced end of the pinion 30 is a pawlcarrying disk 33, said disk having on the hub thereof a pin 34, engaging in a corresponding hole in the pinion and by means of which they are locked together and move as one piece. A disk 35 is loosely carried on the shaft 24 just in front of the pawl-carrying disk, the outer face being covered with some frictional material 36, such as leather or the like, and is held in frictional contact with the inner face of a ratchet-wheel 39 by a spring 41, surrounding the shaft 24 and pressing against the pawl carrying disk 35. The pawl-carrying disk has a pawl 38 pivoted thereto at 40, said pawl having a short under projection 39,with a slot 40 therein that is engaged by a fixed pin 37 on the friction-disk, acting to throw the pawl into engagement with the ratchet-wheel immediately the pawlcarrying disk is moved. The ratchet-wheel 39 is fixed to the outer end of the feed-roll shaft 24 in front of and in contact with the frictiondisk 35 and engages the pawl on the pawl-carrying disk and directly operates the feed-roll 25 by means of the above-described connections with therack-bar. On the end of shaft 24 is a hand-wheel 42 for manually operating the feed-roll when it is so desired. Thus it will be seen that When the gear-wheel 5 revolves it will operate the rack-bar to rotate the pinion 30 on the feed-roll shaft 24, which in turn operates the pawl-carrying disk, and the pawl on said disk will be thrown down into engagement with the ratchet-wheel by the pin on the friction-disk, said disk not moving until the pawl engages the ratchet, when the pawlcarrying disk, the friction disk, and the ratchet-wheel will move together and rotate the feed-roll 25 the desired distance, whereupon the rack-bar will be drawn down and the pinion 30, pawl-carrying disk, and friction-disk will be returned to their initial positions ready for another operation to progress the feed-roll. When the pawl-carrying disk is rotated backward by the rack and pinion, the frictional disk does not immediately respond, and the pin 37 thereon will lift the pawl out of engagement with the ratchetwheel and then move back with the pawl-carrying disk.

Bolted to each inner face of the side frames above the feed-roll 25 are two brackets 50, to which are secured, by means of bolts, a crossbar 51, that supports the feed-wheels above the feed-roll, and they may be adjusted laterally on said cross-bar so that they do not come in contact with the gummed edge of the paper. The feed-wheels 53 are held in frietional contact with the feed-roll and are rubber-faced and carried by brackets 54, Fig. 6, having upwardly-projecting studs 55, that bear in sleeves 56, said sleeves having enlarged openings in their lower ends, in which spiral springs 57 are lodged and surround the reduced ends 58 of the studs 55, said springs bearing against the shoulders on the studs and the shoulders of the sleeves and tending to force the feed-wheels down against the feed-roll. Extending through the reduced portions of the studs are pins 61, that engage in slots 62 in the sides of the sleeves to retain the feed-wheels in their proper positions on the feedroll. The upper ends of the sleeves 56 pass through longitudinal slots 52 in the bar 51 and are threaded to receive nuts 63, which retain them in position by drawing the shoulders 64 on the sleeves against the under portions of the bar 51, and the studs 55 pass through the sleeves and are threaded to receive the adjusting-nuts 65, and by means of which the pressure of the feed-wheels on the feed-roll is regulated to suit the thickness of paper being used for the flies.

A roll of paper is carried on a shaft 7], j ournaled in the side frame of the machine, and is held in position by plates 72, that are adjustable on the shaft 71 to suit any width of paper. Farther to the rear of the machine is a glue-receptacle 73, supported on crossrods 74, secured in the side frames of the ma chine, said glue-receptacle having a heatingchamber 75 underneath it, to which steam is admitted through the supply-pipe 76, having a controlling-valve 78, and exhausted through the pipe 77, located at the opposite end of the heat-chamber. J ournaled on the glue-receptacle in any suitable manner is a shaft 7 9, upon which is securely mounted the glue-distributing wheel and over which the strip of IIC paper passesafter it leaves'the roll; buti'the paper being of greater width than the gluedistributing wheel it is necessary to have some support for it, and this is accomplished by having a semicircular shield 81 fastened to the side frame and the top of the receptacle, and being of the same diameter-as the glue-wheel and almost touching the face of the same the paper will travel along freely and that portion of it exposed to the glue-wheel will be properly gummed. The paper gummed on the under side then passes down underv an idle roller 84, journaled in the side frame and the top of the glue-receptacle, where it comes in contact with a scraper 82, secured to a shaft 83, ournaled in the side frame and the top of the glue-receptacle, where the surplus glue is scraped OE and runs back into the glue-receptacle. Then passing up around an idle roller 87, carried in the ends of the side frames, the paper passes along gummed side up to the feed-roll and feed-wheels, where it is fed down onto the receiving-table, after which it is cut ofl and secured to the box by operations hereinafter more fully described.

The main body 95 of the box-receiving table, having a frame 95 secured thereto, is bolted to a gooseneck bracket 96, having split journal-bearings that encircle the bearings 26 of the feed-roll 25 and are loosely secured thereto, so as to form a pivot connection for the oscillatory movement of the table. Pivoted to the lower end of the table is a toggle-link 98, to which is pivoted an under toggle-link 99, said under toggle-link 99 being supported on a rock-shaft 94, journaled in the side frames of the machine at 1001and pivoted to the table toggle-link at 101, therey forming a toggle-j oint connection for raisingand lowering the table. J ournaled on a rod 102 in the'side frame is a downwardlyprojecting cam-lever. 103, pivoted at its lower end to a rod 104, connected with the lower toggle-link 99, said cam-lever carrying a roller 106, that travels in a groove 107 in the face of a cam 108, fixed to the auxiliary shaft 6, said cam giving a backward-and-forward thrust to the cam-lever, thereby moving the connecting-rod 104 and operating the togglejoint to' raise and lower the table for each revolution of the cam with the auxiliary shaft. The connecting-rod 104 has a right and left handed nut or' turnbuckle 105, adapted'to shorten or lengthen the rod for adjustingthe throw of the toggle and the movement of the table. The main body of the table has two vertical holes 115, that re ceive studs 1 16 therein, said-studs protruding beyond the top plane of the table and are secured to a dovetail key-bar 117, that lies longitudinally along the top of the table and has slidably arranged thereon dovetail grooved blocks '1 18, ada ted to receive the fly and the box to which t e fly is secured, as shown in dotted lines in Fig. 8. The dovetail slots ,journaled on the rod'102, the lower arm of 117 inthe'slidable blocks are of 'greater de pth than'the thickness of the keybar, so that when the key-bar is released by turning the The stud is thendrawn down by the handwheels, in turn forcing the key-b ar against the table and locking the slidable blocks in the desired positions, as .seen in Figs. 7 and 8. The number of'slidable blocks on the key-bar is one less than the number re uired to completely occupy the surface of t e key-bar, so that sufficient space is left to adjust the blocks for the diflerent sizes of boxes. i

The flyholding plate 125 extends forward on the :table far enough to cover the fly, with the exception of the gummed portion, and has downwardly-projecting pins 126 on the rear edge thereof, that slide in holes 127 in the rear portion of the table-frame 95, the lower end of said pins being provided with heads that abut the lugs 128, secured to the side frame of the machine, and springs 129, surrounding said pins and held in position by the heads on the pins and the bottom of the table. After the fly has been fed onto the table the table i rises, the pins 126 are removed from contact with the lugs 128, and the fly-plate is drawn down against the ungummed part of the fly by the springs 129 in such manner that the plate will securely hold the fly until the presserbar has operated and the table has returned to the position shown in Fig. 1, when the flyholding plate will'be raised againand another fly fed down onto the table.

The paper-cutting mechanism consists of a U-shaped bracket 130, havin split journalbearings 131, Fig. 3, that are loosely secured to the'feedroll shaft 24; the end of the bracket 130 extending along the inner end of the ta+ ble in an oblique direction (see Fig. 3) and has adjustably secured thereto the knife 132 y neath the knife-bracket and fastened thereto is an elongated: curved late134, that serves as a guide and hold-up or the paper after the knife has descended. The loose end of the continuous stri of paper is supported on the plate 134, an when the knife-bracket returns to the position shown in Fig. 1that is, the initial condition of the machine-the bottom of the plate 134 will be flush with the tops of the slidable blocks 1 18, so that the paper can again be fed down onto the table and the machine be ready for another operation. The inner end of the table-body 135 serves as an opposing shear-block for the knife, so

that when the obliquely-arranged knife descends it will have a shearing action'and cut the paper in a clear and'decisive manner. A rod 136 is pivoted to one side of the knifebracket and extends down to'and is pivotally connected with a bell-crank lever 137,

means of'screws 133. Located under IIO the bell-crank carrying a roller 138, that rides in a groove 139 in the face of a cam 140, fixed to the auxiliary shaft 6, said cam operating to raise and lower the knife-bracket for each revolution of the auxiliary shaft 6.

After the box has been placed inposition on top of the fly lying on the slidable blocks secured to the table the table is raised until it meets the presser-bar 144. The presser-bar is preferably rectangular in shape, is of suflicient width to cover the gummed portion of the fly, and is pivotally connected to the lower toggle-links 145, pivoted to upper togglelinks 146, said upper toggle-links pivotally dependent from the supporting-arm 148, secured to the top and side of one of the side frames, and a bar 150, that serves to connect the two toggle-joints together, is secured to the operating-lever 151 by a link 152. This operating-lever is journaled on a stud 153 to the side frame and has pivoted thereto above the said 'ournal a connecting-rod 154, provided wit an elongated right and left threaded nut or turnbuckle 155 for regulating the throw of the operating-lever. The opposite end of this connecting-rod is pivotally connected with the cam-lever 156, j ournaled on the stud 102, said cam-lever carrying a roller 157, that travels in a groove 158 in the face of a cam 159, that is fixed on the auxiliary shaft 6. Attached to the bottom of the presserbar is a piece of soft material 160, such as rubber or the like, so that the box when brought in contact with the presser-bar will receive sufficient pressure at all points to make the fiyadhere firmly thereto.

The cams controlling the paper-cutting knife, the box-receiving table, and the presserbar are mounted on the auxiliary shaft 6, driven by the main shaft, and are so arranged and timed that they will cause the paper cutting knife to descend simultaneously with the upward movement of the table, and the presser-bar will begin to descend when the table has about reached the limit of its upward movement, so that when the presserbar meets the table sufficient pressure will be exerted to secure the fly to the box. (See Fig. 3.) After this operation as the cams continue to rotate they will cause the table to descend, the paper-cutting knife to ascend, and the presser-bar to recede to their initial positions ready for another operation, as shown in Fig. 1.

The operation of the machine is controlled by a treadle 161, located on the operators side of the machine and having a short shaft 163 rigidly secured thereto, that is journaled in arms 162, bolted to the side frame and ex tending inwardly under the table. The shaft 163 has fixed thereto an upright standard 164, provided with a semicircularly-grooved head 165. on the top thereof and vertical slots in the side of said head that receive a horizontal pin 168, carried by the clutchshifting rod 167, that is journaled in the side frames, said clutch-shifting rod having secured on the end opposite the treadle an arm 170, that engages the clutch 169, secured on the end of the main driving-shaft. Thus it will be seen that when the treadle is depressed the short shaft 163 will be rocked, thereby moving the upright standard 164, engaged by the pin 168 in the clutch-shifting rod 167, thereby drawing the clutch-rod toward the operators side of the machine and causing the arm 170 to force the clutch into engagement with the drivingpulley 3 and start the operation of the machine. Any standard form of clutch may be employe, as the particular construction of the clutch forms no part of this invention.

The operation of the machine is as follows: Presuming the paper to be in position to be operated upon by the feedroll and feedwheels, power is applied by depressin the treadle and through its connections with the clutch-rod throwing the clutch into engagement with the drivingpulley, thereby rotating the main shaft and the pinion on the end of said shaft driving the gear 5 and the auxiliary shaft 6. An intermittent forward feed is given to the feed-roll by the gear 5, operating the rack-bar that meshes with the pinion loosely mounted on the bearing of the feedroll shaft, said pinion intermittently driving the pawl-carrying disk, the friction-disk, and the ratchet-wheel secured to the feed -roll shaft and operated by the pawl on the pawlcarrying disk. For each upward movement of the rack-bar the feed-roll and feed-wheels are operated and the paper with the gummed side upward is fed forward and down onto the table, when the feeding will cease because the rack-bar has reached the limit of its upward throw, and as the rack-bar descends it will carry back withit to the initial position the pinion, the pawl-carrying disk, and friction-disk, the ratchet-wheel remaining in its progressed position. The knife-controlling cam, located on the auxiliary shaft 6, driven by the gear 5, having by this time rotated a sufiicient distance to reach the operating portion thereof will draw down the bell-crank lever 137 and rod 136, connected to the knifebracket, and start the knife in a downward direction, The box to which the fly is to be secured is then placed over the fly that rests on the slidable blocks on the table, and simul= taneously with the above.- described action the table-controlling cam on the auxiliary shaft 6 will be in position to draw the cam.- lever arm 103 toward its axis, thereby giving a thrust to the connecting-rod 104, that will operate the toggle-links 98 and 99 and gradually straighten said toggle-joint and cause the table to ascend. The descent of the knife and the ascent of the table will produce a shearing action between the knife and the end of the table, and the paper will be severed The presser-bar is operated at the same time by acam located onthe auxiliary shaft 6, that forces the cam-arm 156 away from its axis, which will give a thrust to the connecting-rod 154, thereby pulling the long operating-lever 151, that in turn will operate the toggle- links 145 and 146 to force the presser- 7 they .continue to rotate the reverse actionwill take place, the knife will ascend, the tabar down against the table when the table has reached the limit of its upward movement, as shown in Fig. 3. After the cams have operated in the manner described and ble descend, and the presser-bar recede to the positions shown in Fig. 1.

Having thus described my invention, the following is what'I claim as new and desire -to secure by Letters Patent:
