MACHINE FOR MAKING CORNER MOUNTS.

Application filed June 17, 1924, Serial No. 720,540. Renewed November 29, 1926. g

tions of the mount. Because of the small size of such mounts, the work of preparing them for use takes considerable time and requires delicate fingers and infinite patience which is extremely arduous and nerve racking to the ordinary person, and for these reasons, such vmounts, although attractive and artistic in appearance, have not gone into the general use which their advantages would. warrant.

The main object of my invention is the for producing closed corner mounts which are ready forinstant use without involving any work on the part of the user other than moistening the adhesive coated 'back of the mount and placing it in position. I

In its preferred embodiment, my invention contemplates a machine adapted for mak- .ing and delivering complete closed corner mounts in a continuous manner and at a high rate of speed. The corner so designed to be made comprises a Hat body-portion having on one face a right-angled pocket adapted to receive and hold the corner of a card, photograph, or other similar article, the back face of the said body-portion be ing coated with adhesive whereby the cornor may be affixed in any desired position to the page of an album. For mounting a card, four cornersare employed, and after being aflixed in proper location, the corners of the card or other article to be mounted are inserted in the pockets of the corners, the card covering up or concealing the body:

portions of Wm, leaving only the provision of a simple and eflicient machine faces of the pockets visible, which if,wel]

and artistically made serve rather to en hance the mounting of the card. In the machine hereinafter described, the corners are made from two endless strips of suitable material fed through the machine, 65

the finished corners being discharged at the delivery end in a continuous stream. The body portion of the corner is formed fromone of said strips which is of the exact width of the corner coated with adhesive on its bottom side. In introducing this strip into the machine, its forward end is squared and the corners are cut off diagonally so that when the cut-off corners are turned over upon the body portion at an angle of fortyfive degrees with the longitudinal axis of the strip, the turned over portions form flanges in right angled relation to each other and with a right-angled cap later applied make up the right-angled corner receiving'm pocket. The body strip is fed through the -machine in a step-by-stepmanner, each step being the length of one corner, and passes over a 'die plate where means areprovided for turning up the two pocket forming flanges and then for wiping the said flanges downwardly toward the body portion. From this point, the strip is fed forward against a stop in position to receive the ca means being provided during this period or holding the flanges down upon the body portion until just before the cap is applied.

The cap is perforated from a second strip of suitable material which is preferably fed intermittently through the machine at right angles to and slightly above the body strip and over a die plate, and as soon as the body strip is fed forward, a reciprocating punch descends, perforating the cap from the cap strip, carrying it downwardly through the die plate and pressing it upon the turned over flanges of the body strip, thereby completing the corner. Since the body strip is coated with adhesive on its bottom side, the upper faces of the turned over flanges present adhesive coated surfaces and means are provided for moistening the cap strip so that the cap is in a moistened downward movement of the punches, there-' fore, a corner is completed and out off and on the upward movement the flanges on the next corner are turned upwardly and wiped over and before the punches complete their next full downward stroke, the strip is fed forward in position to receive the cap.

The frame- Referring to the drawings, the frame of the machine may be made in any suitable form, butas shown comprises two upright goosenecked ribbed standards spaced apartfor supporting the driving or operating mechanism and a sub-base plate 31 for carrying the dies and their co-ordinate mechanisms. The standards and plate may be made in one casting and theplate may be provided with ears 32 whereby the frame may be fastened by bolts 33 to a plate 34 supported on legs 35 which may be made in pairs, the two legs of each pair being connected by a web 36. The frame and its supporting structure should be sufficiently substantial to' prevent undue vibration when the machine is'run at a high speed.

The driving mechanism:

' shaft itself, as hereinafter set forth in demazes?- may be connected to a-suitable source of power by a belt. Oil'cups 4.5 are arranged on the bearings 41 for purposes of lubrication. The reciprocating punches may be driven by the crank arm 46 of the shaft and various other co-ord'inatemechanisms may be actuated in various ways from the tail. p

The (lies and punches. Crosswisethe machine, with their longitudinal axes in alignment, are arranged two die-plates 50 and 51, and above, mounted for co-operation therewith, are two reciproeating punches 52 and 53. The die-plates maybe supported upon the frame of the machine in any suitable manner as by a plate 54 and a block 55, preferably of hardened steel, plates 56 and 57 of different thickness being interposed between the block and the die-plates 50 and 51 respectively in order 1 to mount the two die-plates at different levels.-

The die-plate 50, which may-be termed the body die-plate, since that strip of material from which the body portion of the corner is made is fed over it, is' provided with a longitudinal cutout guideway 58 (Fig. 9) through which the body strip is fed and the forward end of the plate is centrally squared at 59 and provided with oblique corner faces 60 at angles of forty-five degrees to its axes,

so that when the finished corner is severed, the end of thebody strip is left in suitable shape for the formation of the next corner.

A? top-plate 62 (Fig. 15) vmay be fastened on the body die-plate by screws 63 which serve also to secure the die-plate in position. At its forward end the top-plate is cut off to expose the forward angular end of .the

. die plate and is provided centrally with a suitable opening 64 to give access to the paper strip within the guideway in case of breakage. may be both provided with a central longitudinal open recess 65 which bifurcates their rear ends to permit the feeding device to be placed in close relation thereto.

The cap die-plate 51 is of general rectangular form and on the under face of its forward end is provided with a recess (Fig. 11) adapted to receive the corner as it is fed forward to' receive the cap, the

back wall of said recess serving as a stop to position the body portion of the corner. On its top face, the plate 51 is cut out from side to side at 71 to permit the cap strip to be fed laterally across it and a vertical right-angled through and through opening 72, the exact shape of the cap to be applied, is out vertically through the forward end of the plate 51. In order to secure a shearinggaction asthe punch cuts the cap in The die-plate and top-plate Y passing downwardly through said opening 5 72, the top face 73 is pitched from the center downwardly toward each side (see' Fig.

11). A. top-plate 74 may be secured to said die-plate 51 by screws 7 5, the die-plate itself being secured in position on the block 55 by screws 76; the top-plate serving to guide the cap strip over the cap-die and having end portions 76 forengaging the forward end of the said die. f An opening 77 maybe providedin the 'top-plate for-the passage,

of the cap punch.

The two punches 52 and 53 may be mounted ina plunger plate 80 in position plunger plate 80 and to be held therein by a set screw 82 threaded laterally through the said plate 80. A plate or flange portion 83 between the punch proper and the shank overlaps and abuts the under face of the plunger plate and thereby regulates the positioning of the punches therein. (Fig. 7.) The plunger plate may be made in any suitable form, but is shown (Fig. 3) as generally square in plan with the side portions cut away to reduce the weight and to'leave corner extensions 85, each bored to receive a bushing 86 which forms a bearing for a guide pin 84 set upright in the block 55. Between the bloek'55 and plate 80 a helical spring 87 may be mounted on each-pin to counter balance the weight of the plunger plate and thereby relieve the strain on the operating mechanism. For-imparting a reciprocating movement to said plunger plate, it is secured in any suitable manner such as by brackets 90 and screws 91 (Fig; 7 to the lower end of a plunger 92 which at its upper end is pivotally connected to a turnbuckle 93 (Figs. 1 and 2) which in turn is connected at its upper end to a split collar 94 mounted on the crank arm of the shaft 40 and provided with an oil cup 95 for lubrication. A yoke bearing cap 96 may be fastened by bolts 97 to intermediate projections 98 on the standards 30 whereby the plunger is guided ,inits reciprocation.

Edge turning mean .9.

, i In order to turn up two edges of the forward end of the body strip to form flanges inright angled relation to each other for receiving the pocket-forming cap which is thefirst operation in the making of a corner, the body die is provided with a tongue located above the body stri as it is fed through the dieand adapte to be pressed down into a suitable recess 101. igs. 9 and 10.) The recess is formed by countersinking the floor of the guideway 58 in its forward portion. The rear wall 102 of the recess is transverse the guideway, but the forward walls 103 and 104 are arranged at right angles to each other and at forty-five degree an les to the axes of the die-plate 50, the point of their junction being at the front face 59 of the die. The tongue 100 is preferably secured by rivets 105 to the under face of the top-plate 62 and therefore lies above the body strip fed through the guideway 58. The forward end of the tongue is right angled with the point 106 of the angle in the center corresponding in shape there-,

fore to the-shape of the recess 101 and the tongue is so locatedthat when it is depresesd into the recess there is just room enough between its forward edges 107 and 108 and the walls 103 and 104 of the recess to accommodate tightly the material used for the body portion of the corner. The edges 107 and.108 of the tongue may be thinned down to facilitate the wiping operation and a rec tangular opening 109 may be centrally disposed for registering with a similar opening in the top-plate.

For depressing the forward end of the tongue into the recess at the pro er times, any suitable means may be provide and one such is shown, comprising an arm 110 (see Figs. 7 and 15) pivotall mounted midway in a bracket 111 secured y the screws 63 on one side of the body die-plate and having its front end bent laterally and downwardly to engage the tongue at point 112 and its rear end provided with a laterally extending roll 113 adapted to engage a cam 114 mounted on the body stri feed shaft described hereinafter. The ront edge of the top-plate 62 may be provided with a semicircular recess 115 (Fig. 15) to afford the forward end of the arm 110 free access to the tongue and a spring'116 secured at one end to the rear end of the arm 110 and at its other end to the plate 54 holds the arm in engagement with the cam.

The wiping means.

a base-plate 123 fastened. to the block 55' by screws 124 and a top-plate125 held in by a spring 163 mounted in two place by screws 126, the top-plate being provided with a longitudinal groove or guideway in which the wiper slides (Figs. 5- and 6). The wiping ends are bent downwardly and then horizontally, the body ortions of the wipers being above the bod -die over which the wiping is done.

. The wiping action is accomplished by the longitudinal movement of the wipers, preferably actuated by the reciprocating movement of the plunger plate through the following means. Each top-plate 125 of the wiper casing is rovided with a longitudinal slot (Fig. 3i through which projects upwardly a lug 131 integral with the wiper 120 (Fig. 6), which lug connects by a bellcrank lever 132 and a link, 133 with the plunger plate, 80. The bell-crank lever 132 in each case is pivotally mounted on a fixed shaft 134 carried by a bracket or bearing 135 fixed on the'block 55 and the link 133 is pivotally mounted at its upper end on a shaft 136 held at its ends in straps 137 fas tened to the top face of the plunger plate by screws 138. The wipers are therefore moved laterally by the reciprocating movement of the plunger plate, being thrown inwardly to wipe on the upward movement of the punches and being retracted on the downward movement. To permit relative movement between the lug 131 and bellcrank lever 132 the lower arm thereof is provided with a slot 139, allowing the pivot pin 140 to move therein as the wipers are retracted. a

The body-strip feed.

For feeding the continuous strip of suitable material from which the body portion of the corner is made, intermittent feeding means maybe provided, one form of such means comprising a feed roll having a resilient cam 151 mounted thereon and adaptedto co-operate with an idler roll 152 for feeding the body strip forward the desired distance on each revolution of the feed roll. (Fig. 8.) On one side of the machine, the block 55 is cut out to permit the feeding mechanism to be placed in said recess and close to the rear end of the body die-plate 50. Within said recess are fixed two upright end-plates 154 having each a lateral extension 155 adapted to be fastened to the top face of the block 55 by a-bolt 156, (Fig. 5), and the said end-plates sup port the idler shaft 157 and the feed roll shaft 158, these two rolls being centrally positioned each on its respective shaft by collars 160. The feed-cam 151 is pivotally mounted near its forward end between two ears 161 on a pin 162 held by said ears, and the rear end of said cam is held outwardly o posite pockets in the feed roll and inner ace of the cam respectively. Since the cam is pivoted away from its forward end, the latter acts. as a stop tolimit the outward .movement of the rear-end of the cam under the surfaceon the idler roll are somewhat narrower than the width of thebody strip to be fed and the tworolls are so mounted as to feed the stri b engagement with it on .its central longltu mal axis. To avoid any buckling of the body [strip in' front of the feeding mechanism, the rear ends of the body nuts se.

die-plate and top-plate are each provided with the longitudinal recess 65 which permits the feed to be placed within the body die-plate where the lon itudinal edges of the body stri at either si e of thefeed is held against fo ding or buckling bet'ween the topplate and the die-plate.

The feeding mechanism may be operated preferably from the main shaft 40. The feed shaft' 158 is extended to one side through a ri 'ht-angled bearing bracket 170 mounted on te block and provided on its end with a spiral gear. 171 which meshes with a similar gear 172 (Fig. 5) on the end of a shaft 173 arranged at right angles to said feedin shaft along the adjacent side of the mac ine and slgiported in bearing brackets '174'and 175. shaft 173 carries a spiral gear 176 (Fig. 3) meshing with a similar gear 177 on the lower end of a shaft 178 (Fig. 1) arranged in approximately vertical position and carrying on its upper end a spiral gear 179 which meshes with a similar gear 180 (Fig. 2) fixed on the main shaft '40 whereby the feeding shaft is rotated one complete revolution for each revolution of the main shaft.

A bearingbracket 182-may be fastened by bolts 183 to the plate 54; to give additional support to the end of the shaft.173 and the shaft 178 may be sup orted on one of the standards 30 by suita l) 185. Wherever'n'eeded to take up the lon itudinal thrust, ball bearings; 186 may e arranged on the shafts 158, 173 and 178 and the spiral gears ma be held on their respective shafts byysuita 1e washers 188 and The flange holding means.

For the purpose of holding down the turned over flanges of the-body portion while it is being fed forward into cap receiving position and until just before the cap is applied, a pair of movable wire fingers may be provided with means for moving them into and out of operative position at the exact times required. The two fingers 192 t its other end, the 1 le bearing brackets the machine in any suitable manner to may be slideably mounted in two bores, circular in crossection running longitudinally the cap die-p ate, said bores being formedby cutting opposite semicircular grooves in the engaging faces of the cap die-plate 51 and supporting plate .57 11) so that each bone is located half in the die-plate and half in the under plate. The rear ends of the fingers may be turned upwardly at right angles and anchored by pins 193 in an upright block 194 on the top face of die-plate 51 and vertical .slots 195 in said die-plate may be provided topermit the block and wires to be moved longitudinally the dieplate (Fig. 13). The forward end of each 8 finger IS HIIClGI'CIIt (Fig. 14) to form a sharp point which is uppermost so that when the bodystrip is fed forward it slides under the rightblock 194. The withdrawal of the an 05 gers 192 from the turned overflanges to per mit the cap to'be applied thereto may be accomplished by means of a hook-shaped cam 203 depending from .the plunger plate which engages the bevelledtop edge of the upright finger carrying block 194 and pushes it rearwardly against the pressure of the spring 198. By mounting the retracting means upon the plunger plate the withdrawal of the fingers may beitimed to such 1 a nicety in relation to the application of the cap by the cap punch that the flanges do not have time to resume their natural form and turn upwardly between the withdrawal and the appli.cation.- When the plunger plate moves upwardly, the spring 198 forces the block 194 and fingers 192 back to normal position.

Gap atnp feed. "5

fabric actuated by feed rolls maybe provided, "the belt also serving as a delivery means for the completed corners, The endless belt 210 may be arrangeddin eliver the cap strip through the cap die and to carry the completed corners to the delivery endofthe machine. It travels from the rearto the front or delivery end of .the machine (Fig. 1) passing under the adjacent or forward ends of the two die-plates then between two feed-rolls 241 and 212 at the delivery end, over a delivery shelf and back under the machine over rolls 213, 214, and 215. Any suitable means may be provided for guiding the belt to prevent its shifting laterally as it enters the machine such as two collars 217' mounted on a pin 218 fixed in one of the standards 30; the collars being held in adjusted position on either-side of the belt by set screws 220 which are purposely elongated to facilitate manipulation. To keep the belt taut a spring tension device 221 carrying a roll 222 on its upper end may be provided. The movement of the belt through the machine is produced by the two co-operating feed-rolls 211 and '212, the former of which is driven and the latter of which is an idler and is yieldable in. relation to the former. The two feed rolls.211 and 212 are fixed respectively on shafts 213 and 214 which are mounted in collar bearings 215-carried by end plates 216 and 217 respectively. The plates 216 may be supported on a table 218 secured to the under face of the block 55 (Fig. 6) and may be held thereon in upright position by screws 220. The end plates 217 are each loosely mounted above a plate 216 on two screws 221 threaded into the upper part of the said plate 216 and the weight 'of the roll 212 and its end plates normally causes the roll to-engage the under roll 211. (Fig. 5.) In order to hold said upper roll or idler, however, in feeding engagement with the lower roll, while permitting it to yield for varyingthickness'es of stock, the

two screws 221 in each end plate are connected together at their tops by a plate 223 held thereon by nuts 224 and set nuts 225 and a spring 226 bearing at its upper end against the. plate 223 is inserted under compression in a pocket in the top .of the end plate 217, The downward pressure exerted by the two springs 226 may be regulated by I adjustment up or down of the two connecting plates 223. In case the cap applied to the corner is embossed, then the idler roll 212 should have a cut away portion or re-v duced diameter 230 to allow the embossed portion of the corner to pass between said rolls to the delivery table without being subjected to a pressure which would tend to flatten the embossing and obliterate it. (Figs. 3 and 23).

As shown, the feed rolls are actuated in a step-by-step manner from the main shaft. The shaft 213 of the lower roll may be extended on one side. being supported at its end by a bracket 232 secured to the plate 54 by a bolt 233, and may have fixed thereto a ratchet wheel 234 adapted to be operated, to turn said shaft, by a dog 235 carry-ing a pawl 236 and being loosely mounted on said shaft: The dog is pivotally connected to the lower end of a rod. 238 which at its upper end is pivotally connected to a crank-disk 239 fixed on the end of the main shaft. In

order to make possible an adjustment of the length of feeding movement, the rod 238 may be connected to the crank-disk in such a way that the elfective throw of the rod.

due to the rotation of the crank-disk may be varied by changing the point of pivotal connection. For this reason the crank-disk may be provided with a diametrical slot 240 undercut to receive the head of a pivot pin- Moistening ale vice for-cap strip.

Any suitable means may be employed for moistening the cap strip to effect adhesion between the perforated cap and the adhesive coated flanges to which it is applied and one form is shown (Fig. 1) comprising a small water receptacle 250 secured to a bracket 251 fastened in turn to the table 34 and a roll 252 mount'ed therein for transferring moisture from the water in the receptacle to the cap strip fedover said roll in engagement therewith. To insure contact between the cap-strip 255 and the roll 252 any suitable tension means may be provided, such as a small weight 256 loosely mounted on pins 257 fixed on a bracket 258 at the entrance to the water receptacle and a fixed spring finger 260 at the exit. In leaving the water receptacle the strip passes over the upper edge 261 of the exit endthereof and a transverse finger 262 may be arranged within the receptacle above the water level but sufliciently low to hold the cap-strip down upon the roll 252 and in'engagement with the edge 261 so that the surplus moisture nay be removed from the strip and run back into the receptacle.

Impression table.

moved downwardly by the cap punch to a bumper where the final pressure is applied.

The table 270 may be supported on two upright pins 272 which are movably mounted in suitable bores in the'plate 54 and block 55 (Fig, 6) and pivotally connected at their lower ends to a yoke 273 which may be provided midway with lateral upturned ears 274 whereby it is in turnpivotally connected.

by pins 275 to two brackets 276 fixed to the under side of the plate 54. (Figs. 7 and 12.) The rear end of the yoke 273 may be pivotally connected by a pm 277 to the lower end of a frame 278 made u of two plates connected at their uplper en s by a pin 279 carrying a roll 280. or controlling the position of the table; a cam 281 is fixed on a shaft 282 arried by brackets 283 secured to the bloc 55 by screws 284, which cam engages the roll 280 and thereby reciprocates the frame 278 and table 270 through the medium of the yoke 273. The plates of the frame may be slotted at 285 to permit this movement of the frame in relation to the shaft 282. For operating the cam 281, theshaft 282 is extended on one side (Fi 3) and provided with a spiral gear 287 mes ing with a similar gear 290 on a shaft 173, the end of shaft 282 being supported in an upright bracket 291. To hold the table 270 'in an uppermost position except when lowe'red by *the operation of the cam, springs 293- bearing at their upper ends against the under side of the table at each end may beplaced in suitable pockets formed in the top of the block 55. (Fig. 6.)

'- Bumper mechanism.

To receive the final pressure of the cap punch a bumper mechanism may be provided consisting of an inverted cup-shaped cap 300 mounted on a circular block-301 fixed on the upper end of a large screw 302 threaded through the plate 54', the block 55 being cutout at 303 to receive the bumper. The cap should fit the block 301 sufficiently closely to avoid any tilting action on its part when subjected to the pressure of the punch, but the block may have a plurality of vertical grooves 304 out in itsperiphery to facilitate the removal of the cap there from when necessary. To secure a certain amount ofv resiliency in the bumper and thereby avoid shock and wear upon-the cap punch in the rapid operation of the machine, a disk cushion 305 (Fig. 22) may be interposed between the two, which cushion may be made in any suitable manner. Preferably it is'made up of a layer of rubber or rubber composition between two layers of fabric anda lurality of circular openings or holes may be punched through the cushion at variouspomts to render it more compressible.

The bumper may be vertically adjusted by turning the screw 302 in one direction or the other through the plate 54, the head 307 of' the screw being pierced by a handle bar 308 (Fig. 7). A block 310 secured on 'the under face of the plate 54 by a rivet 31] increases thebearin surface for the screw. A set screw 314 having a head 315 and handle bar 316 is threaded on the screw 302 in order to hold it, the bumper-screw, in adjustedpositi'on. Since the stroke of the cap punch is constant the amount of pressure to which the cap portionof the corner is subjected on the. completion of the corner is regulated by vertical adjustment of the bumper mechanism.

Rewinding mechanism.

Since the caps are punched out of the cap ets 321 fastened to the frame of the machine or by the bolts 97 used to secure the plunger cap in position and the reel may be frictionally turned by a belt 322 running over a groove 323 in the hub of the wheel 43 on the main shaft.

I Operation of the machine.

7 In Fig. 23 is shown thecorner which the machine is adapted to turn out; the cap and the body ortion of the corner being separated to illustrate more clearly the exact construction. In that view 330 designates the body. portion of the corner, 331 the turned over corner edges or flanges with the adhesive coated sides uppermost in position to receive the cap 332 which is shown with an .embossed design. The rear edge of the corner is of such form that the body strip is left in proper condition for the formation of the next corner.

In the use of the machine for making corners two continuous strips of suitable material such as paper are fedin'to the ma chine, the cap strip 255 from a roll 340 at the rear of the machine, and a body strip 341 from a roll 342 on one side of the ma chine. The body strip is of the exact width of the corner desired so that: there'is no waste audit is coated with a suitable adhesive on its bottom side. It may be of thinner material than the cap strip which should be sufliciently heavy to make a strong corner-receiving pocket and to retain any design which may be embossed thereon by the ca punch. The body strip 341 passes from t e roll 342 through a suitable tension device consisting of small weight plates 346 loosely supported on a bracket 348 secured to the plate 54, thence between the feed-roll 150 and idler roll 152, and through -the guideway '58 in the body-die. The cap str p 255 passes from. the roll 340 through the moistening device, through the cap-die and finally between the feed-rolls 211 and 212 to the rewinding reel.

The machine .isdesigned to. operate c011- tinuously and at a speed of from two hundred and fifty to four hundred revolutions a minute, turning out a complete corner sure is applied.

On the upward stroke of the plunger plate and punches after a completed corner is severed from the body strip leaving its forward end in shape for the next corner, thefinger 110 is operated by the cam-roll 114 to depress the tongue 100 to press the forward end of the body strip into the recess 101 and to turn up the corner edges in right-angled relation to each other. This operation may be timed to take place just after the severing of the" I plunger plate, the Wipers are refracted, the

depressing finger raised and the tongue released whereupon the feed-roll 150 is timed to feed the body strip forward under the adjacent end of the cap-die and under the flange or edge-holding wire fingers 192. These fingers continue to hold down the turned over edges of the corner until just before the cap is applied,.when they are suddenly retracted by means of the block 194 and cam 203, this operation being so timed that the cap is applied before the flanges.

Meanwhile, the cappunch has perforated a right-angled cap from the cap strip carried it downwardly through the opening 72 and applied it to the turned over flanges on the body portion carrying the corner, which is severed from the body strip at the same time by the other punch 52, belt 210 and table 27 0 downwardly to the bumper cap 300 where the final pres- The cap strip and belt are fed forward one step just after the cap punch has on its upward movement passed out of the cap die,

this feeding movement causing the cap strip to present a .new surface to the cap punch on its next downward trip and the belt-to move the completed corner one step toward the delivery end of the machine. There the belt passes over the edge of a table 360 where the corners are stripped from the belt and slide down an inclined shelf 362 connected by hinges 364 to thetable 360 and adjustably supported by a bar 366 so that the finished corners may be delivered into a suitable receptaclo.
