DECALCOMANIA TRANSFERRING MACHINE.

Israel Orswell, Los Angeles, Calif.

Application May 6, 1940, Serial No. 333,558

21 Claims. (01. 41-1) The machine of this invention is intendedto operate or function in such manner as to effect the transposition of a decalcomania from its backing to an object to be decorated by the decalcomania.

Briefly stated, a decalcomania is a pictorial or other representation builded up by layer on layer of color. Each succeeding color being superposed upon the first as to develop harmony and composition. Usually the colors so builded up, rest upon a water soluble gum coated upon a strip or sheet of paper which forms the vehicle for moving the representation after its creation. Decalcomanias are formed of pigments having different characteristics, that is; some decalcomaniac are formed of pigments which are fusible when subjected to heat, hence when a decalco-' mania is transferred to a vitreous surface and is then fused thereto, the pigments must naturally have a lower fusing point than the surface to which or upon which it is to be fused.

Accordingly it is a prime object of the present invention to provide a machine which will transfer a decalcomania from its backing to an object adapted to receive the same, either for the purpose of simple adhesion thereto or for the purpose of being fused thereto by the subsequent application of heat.

Another object of the invention is to provide a machine in which the decaloomania is removed from its backing by the application of pressure contact thereon, and by subsequently applying a laterally directed pressure to slip the decalcomania from its backing.

A further object of the invention is to provide in a decalcomania transferring machine, means to support a wetted decalcomania upon a resilient surface which is movable in a horizontal plane and then to apply a downward pressure upon the decalcomania whereby a transferring head is brought into firm contact therewith; and subsequently operating means based upon a latcral motion to remove the decalcomania from its backing and apply the same upon a receiver.

A still further object of the invention is to provide a decaloomania transferring machine in which a decalcomania is first wetted and is then subjected to downward pressure and then subsequently applied lateral pressure in order to remove a decalcomania from its backing for afflxation to a receiver.

A still further object of the invention is to provide a machine to transfer a decalcomania in which a swingable head is brought into contact with the decalcomania and which is then;

swung laterally to slip a decalcomania from its backing for aflixation upon a receiver.

A still further object of the invention is to provide means to impregnate a decalcomania support with water to loosen or soften the gum base thereon, said means comprising a continuously varying hydrostatic pressure applicable thereto.

Another object of the invention is to provide an intermittently operated means to conduct a decalcomania and its base support through a water bath wherein a constantly varying hydrostatic pressure from immersion to emergence therefrom is adapted to facilitate softening of the gum base used to secure the decalcomania upon its backing, whereby the decalcomania can be readily removed from the said base.

Still another object of the invention is to provide in a transfer machine of the character contemplated, a head construction for transferring decalcomanias and the like, which includes a plane and horizontal transfer contacting surface so formed and arranged as to be deformable Within limits, whereby a decalcomania can be aflixed upon a concave and/or convex surface with equal facility as upon a plane surface.

Other objects, and/or features, and/or advantages of the invention may appear from the accompanying drawings, the specification, and appended claims.

Figure 18 is a fragmental detail taken substantially on line Ill-48, Figure 2, showing a decalcomania positioned between the belts employed in the machine of this invention.

The machine of this invention, may for the purpose of particularizing, be stated to be formed of three divisions which are so co-related in function and service to the other that they form an entity for the purpose of wetting a decalcomania and then delivering the same to definite point for the purpose of transferring the decalcomania from its backing to some object suitable therefor and intended to be decorated by the decalcomania.

In the following specification, detailed reference will be made to the several aforementioned divisions of the machine, and to that end, the

means used to wet and thereby soften the gum base of a decalcomania will be first taken up.

Reference to the drawings will show that a suitable frame is adapted not only to support the machine as a whole, but also a tank 32 cradled therein. As shown the tank is formed with considerable depth so that a decalcomania 61h which is immersed therein and is then moved to a point adjacent the bottom, is subjected to increasing hydro-static pressure, which fact facilitates and shortens the period of necessary immersion to thoroughly saturate the decalcomania backing and the gum base upon which the decalcomania proper rests. Rails 34 of the frame are adapted to support frames 35 and 38 within which a plural number of grooved wheels 46, 42, 44, 46, and 48 are adapted to rotate upon their respective shafts 50, 52, 54, 56, and 58. It will be recognized that grooved drums could be used instead of the several wheels aforementioned and the same result would be had, for it will be seen that the purpose of the wheels is to provide means to guide the belts and 62 through a definite course from adjacent a point of decalcomania supply, downwardly through the tank, and finally to a delivery point which is co-incidental with a central spot upon the table 64 which is also secured upon the rail 34.

Deep within the tank 32, I position wheel or grooved drums 66 and 68 which ar mounted for rotation upon a suitable support Ill and 1 I. These wheels co-operate with the aforementioned ones in guiding the belts to and 62 through the tank 32.

Reference to Figure 12 will show that the belts EU and 62 are respectively formed of a plural number of individual strands which are slightly spacedapart and of which there may be any desirable number. In the present instance there are nine strands or sub-belts in each of the major belts or belt groups 60 and 62. The purpose of this arrangement is to expose as much of the surface of a decalcomania backing as possible to the wetting action of water within the tank 32, and yet provide such a degree of support as to enable the decalcomania to be carried with stability and without marring the same. Reference to the several figures of the drawings, and in particular to Figure 16, will show that the table 64 is provided with a number of grooves in its top surface, there being one groove for each of the strands or sub-belts of belt 62, for this is the belt which moves over the table. The grooves are adapted to receive the sub-belts when the same are pressed downwardly in a manner to be subsequently shown, so that when thus pressed downwardly, the decalcomania will rest upon the top surface of each of the dividing strips 66 between grooves 68.

A motor l0 mounted upon a base 12, and operating through a belt M and a standard gear ratio reduction device 76, including a pulley I8 and shaft 80, is adapted to drive a shaft 82 by means of which all of the m chanism of this machine is driven.

The shaft 82 is journalled in bearings 84 and 86, and is provided with an adjustable eccentric 88 upon the outer end thereof as shown in particular in Figure 7. The eccentric 88 comprises a rectangular block 99 fixedly secured upon the shaft 82 so as to rotate therewith, and is formed with a groove 92 extending the length thereof for reception of a slide 94 which operating within the confines of the groove, is adapted to hold a saddle 96 upon the exterior of the eccentric 88. A thumb actuated screw 68 held against longitudinal movement by plate I00, is adapted to move the saddle 86 with respect to axial alignment with the shaft 82, thereby enabling the saddle '96 and a pitman rod I02 to be moved through an adjustable arc. The free end of the plate I is bifurcated and the prongs thereof operate in a groove I04 of the screw 98. This construction is both simple and practical, and is well adapted to hold the screw against longitudinal movement, and hence when it is rotated the saddle 96 is moved relative to the axis of the crank 88.

The outer end of the pitman rod I02 is formed as a rack, having teeth I06 which are in mesh with the teeth of gear I08 which is free running upon the shaft 58. However, the gear I88 is provided upon its one side with arms H0 and III upon which are carried eccentric rollers H2 and H4. .A wheel H6 is fixedly secured upon the shaft 50 so as to drive the shaft when the wheel is turned, and such rotation is effected when the gear I 08 and the arms IIOIII are moved in response to pressure by the pitman rod I02, for the reason that the rollers H2 and H4 are set with respect to the periphery of the wheel H6 so as to bite or be pinched between the sur face thereof and the axis of the rollers when moved in one direction, while being free to ride over the surface of the wheel when moved in an opposite direction.

A chain I I8 operating circuitously over gears I20, I22, I24, and I26 is adapted to drive the shafts upon which they are mounted so as to impart synchronous motion to each of the afore-mentioned belt carrying wheels, and the whole of this motion, which is intermittent is obtained by the movement of the pitman rod I02 and its co-related accessories.

The frame 34 carries a bed-plate I30 upon which the bearings 84 and 86 are mounted, and also carries a bracket I32 upon which I secure bearings I34 and I36 which journal an oscillatable shaft I38 vertically positioned therein. The upper end of the shaft I38 extends through the bearing I34 and is provided with a radially disposed arm I40 fixedly secured thereto for synchronous movement. Super-posed or positioned above the arm I40, I secure a second radially positioned arm I42 which is loosely positioned upon the shaft I38 whereby the shaft may be oscillated without effecting rotational effort in the arm. The bearing bracket I34a is provided with a bar I 44 fixed thereto, and upon the free end of which a pin I46 is secured for the purpose of forming a stop against excessive movement of the arm I40 and the shaft I38. The arm I42 not only gives the pin I46 stability, but provides an anchorage for a radius rod I48, the use of which will be subsequently set forth. Just above the arm I 42 and extending substantially oppositely therefrom, I place a third arm I50, and this arm has attached to its free end, a spring I52 the opposite end of which is attached to small pin I54, and since the arm I50 i fixedly secured to the shaft I38 the spring I52 operates to place the arm I40 and shaft I38 under a constant pressure which in co-operation with a positive drive to be later described, holds the transfer head assembly I60 centrally positioned over a container or receptacle I62 upon the table-like support I64, because pin I66 secured in the bearing bracket I34a forms a definite stop.

An arm I68 is clamped to the shaft I38 at point I while the opposite end of the arm I68 carries the aforementioned transfer-head assembly I60. A collar I12 upon the arm I68 forms an attachment for a brace member I14, the other end of which is secured to a collar I16 upon the upper end of the shaft I38. This arrangement or a similar construction adds stability to the arm I68.

The free end of the arm I68 is provided with a tubular member I18 which extends a short distance above and below the axis of the arm I68. Upon the upper end of the member I18, I secure a short lever I80 in fixed relation thereto, and this lever is adapted to receive the otherwise free end of the radius rod I48, thus assuring that the transfer head I will be in proper functional alignment when swung arcuately to pick up and then deposit a decalcomania.

The transfer-head I60 is secured upon the lower end of the member I18 and comprises a horizontally disposed plate I in threaded or other connection to the member I18, and is formed with dependent sides or flanges I82, upon which are secured elongated members I84, the outer end of which form journals for rollers I86 positioned between the members I84. These rollers are tubular and are mounted upon pins I88 and I90 which are journalled in the members I84 as above mentioned. The ends of the pins I 88 and I90, which project through the sides of the members I84, are adapted to carry fingers I92 arranged in pairs, and the lower ends of these pairs of fingers are joined by rollers I94, while the other ends of the fingers are each provided with a slot I96 whereby the fingers are permitted a degree of movement, being limited therein because of screws I88 extending through the slots and being fixedly secured in the walls or sides of members Axially aligned Within the member I18, I place a threaded stem I68" upon the lower end of which is secured a small rectangular plate 200 and upon this plate I place a sponge rubber or other resilient pad 202. The upper end of the stem I88" is provided with a nut 204 in face contact with the lever I80 whereby upon turning the nut 204 the stem will be drawn upwardly or if loosened will be forced downwardly by the action of an extensile spring 206 which encircles the stem I98" and which is in abutment with the plate 200 on one hand and an immovable shoulder within the member I18. A perforated belt 208 is secured around each of the rollers I86 and extending downwardly passe over each of the rollers I94 and also across the intervening space including face contact with the pad 202. An extensile spring 210 encircles each of the pins I88 and I 90, and has its one end secured to the inner surface of the cylinder I86, while the other end of the spring is situated within a slot formed in the pins I88 and I90, thereby placing the cylinders under rotational tension to ensure that the belt 208 will always be taut.

For the purpose of function it is necessary that the shaft I88 be made to oscillate and also provide it with a raising and lower-ing motion.

Reference to Figures 4 and 6 among others of the drawings will show that the shaft 82 is provided with a bevel gear 2 I2 which is in mesh with a second and like gear 2 I4 which is secured upon a shaft 2I6 operating Within a sleeve 2I8 formed as an extension of the bearing block 86. A brace 220 secured to the sleeve 2I8 and to the bearing bracket I36a, gives stability to the sleeve 2I8 and the shaft 2 I6 operating therein.

.A cam 222 is secured upon the upper end of. the

shaft 255 and is adapted to rotate therewith, while immediately above the cam I place a rod 226 having a fiared end 226 within which is formed a slot 228 so proportioned as to snugly receive the upper and free end of the shaft 2 I6. A boss 286 pinned to the extreme upper end of the shaft M6 is adapted to hold the rod 224 in contact with the cam and to prevent dislocation thereof. An idler wheel 232 is mounted upon the rod 225 and is in contact with the cam 222 so that rotation of the cam will cause simultaneous movement of the rod 224 which is also connected in pivotal manner with an arcuately movable rack 26 which is fulcrumed upon a bolt 236 in the bearing bracket I 36a. An extensile spring 258 secured at its one end to the shaft 2l6 or rather to the base 260 and at its other end to the rod 224 is adapted to exert a pull upon the rod 224 and the rack 234 whereby the same will be caused to oscillate in response to release of pressure by the cam 222.

The rack 236 is in mesh with a gear 262 which is adapted to rotate or oscillate the shaft I38 because of a keyed relationship operating in a spline 254 formed in the shaft I 38. It is to be noted that the gear 242 rests upon the upper face of the bearing bracket I36a and is held in this position by means of a bar 246 which at its one end encircles the shaft I38 while its other end is held in fixed position by means of the bolt 236. just described apparatus will oscillate the arm I 68 and the transfer head I 66. Apparatus neces sary to lift the shaft 538 and associated parts will now be described.

The shaft 82 is provided with a cam 256 formed with certain lifting faces, the uses of which will be described in the description of operation. A bearing bracket 252 is mounted upon the base I36, and a pin 254 therein forms a fulcrum point for a lever 256, the other end of which is bifurcated, as partially shown in dotted lines in Figure 6, and carries rollers 258 upon the inner sides of the arms 268 and 262 formed by the bifurcation. These roller rest between the faces of collars 264 and 268 which are positioned upon the shaft I38, while an anti-friction roller 268 is pivotally mounted upon the lever 256 in medial vertical alignment with a plane passing through the shaft 82, and since the roller 268 rests directly upon the top side of the cam 256, it accordingly constitutes the sole support for the shaft I88 and associated elements, hence any movement imparted to the lever 256 by the cam 258 will cause the shaft I38 to raise or will permit gravitational lowering thereof.

Reference has previously been made to the power drive used to effect operation of the machine of this invention. In order that operation of the machine may be controlled, I provide a clutch 218 comprising a driven element 212 and a driving element 214 which are joinable upon meshing of teeth 216 which are adapted to be separably dove-tailed when the driven element 212 is forced into engagement with the driving element 218 upon an inward thrust of the manually operated rod 218, as shown in Figure 5.

The table I64 is vertically adjustable by means of a clamp 280 secured upon the frame 66 of the machine, and is adapted to support a decalcomania receiving object I62 in vertical adjustability with respect to the head I66. The object I62 being centered between aligning supports 284 and 286.

Reference has previously been made to the fact that the weight of the shaft and its associated The parts, rest upon the cam 256 by means of lever 2 56. The several figures of the drawings will show that such gravitational effort is augmented by mean of a spring 266, the one end of which is held in fixed relation to the frame 38, while the other end is secured to a metal strap 292 or equivalent device having an over-hanging portion 266 which engage the shoulders of the aforementioned bifurcated lever 256 and thereby exert a downward pressure proportional to the distention of and strength of the spring 268.

Operation of the machine of this invention will be described in the following statement.

Assuming of course that the machine is in good working order, that a supply of decalcomanias rest upon the table 568, and that the tank 32 is filled to a substantial depth with water, and that the motor I6 is idly rotating the pulley wheel 18 (the clutch 216 being disengaged). Upon forcing the clutch control rod 218 inwardly in the direction of the arrow A, the clutch 218 is engaged and operating through the gear-ratio reduction device 16, drives shaft 82 and its crank :38, pitman-rod I62 and the rack I86, which being in mesh with the gear I88 forces the same in a clockwise direction and carrying the arms Ill] therewith, causes the eccentric rollers I I2 and lid to be forced into pressure contact with the wheel I I6 thereby driving the shaft 56 and causing the belts 66 and 62 to travel over each of the several wheels or grooved cylinders 46, 42, 44, 46, d8, 66, and 66. Decalcomanias are now fed from the supply upon table 366 to enter between and carriedby the belts 66 and 62 beginning at point between wheels 46 and 48. Continued belt travel carries the decalcomanias progressively deeper in the tank of water 32, see Figure 18, and readily saturates them by reason of pressure due to hydro-static head.

Heavy lines 884 in Figure 13 indicate the course of travel of the decalcomanias and also the manner in which they are held between the belts. This movement is intermittent due to the backward sweep of the pitman-rod which is permitted for the reason that in so moving the eccentric rollers i I2 and I I4 are free to be drawn over the surface of the wheel H6. It may be here stated that each of the eccentric rollers in the instant illustration are spring actuated by means of the springs 366 to hold the greater axis thereof in face contact with the wheel I I8 thereby acting as a spur to efieot one-way movement thereof.

The machine is so timed as to cause a decalcomania to be delivered at a spot on the table 64 or immediately thereabove, for the decalcomanias now reset upon the taut belt 62, which is in alignment with the medial vertical center of the transfer head I68 and when so placed the whole of the belt system comes to rest pending completion of removal of the decalcomania from its paper or other backing or support.

Assuming that the head I68 is spotted over the table I66 as shown in Figure 2, it Will be noted that the cam 258 on shaft 82 is positioned with its concave face c-d so positioned as to permit the roller 268 and lever 256 to be at their lowest point and accordingly permitting the shaft 336 and the head I66 to likewise be in their lower most position. Movement of the shaft 82 rotates the cam 256 and in so doing cam face d-e pressing upwardly upon the roller 268, causing it and its lever 256, the shaft I38 and the head I66 to be raised to a plane which is just above the belt 62 and the decalcomania thereon and this position of elevation is held by the face d-f of cam 250, being defined by a constant radius from the shaft 82. p

' From the moment that cam face d-gf becomes operable, a second force is brought into action, that is, the shaft 2 I6 driven by gears 2 I2 and 2 I4 causes cam 222 to rotate and to force the roller spring 240 is placed under an increasing degree of tension and hence gives stability to the head I60 in its poised position over the table 64 by taking any possible back-lash out of the just mentioned gear 242 and rack 234.

Continued rotation of the cam 250 will bring.

the face j-g into play and at this time the roller 268 drops slightly permitting the head I60 and associated supporting elements to also drop slightly. This movement causes the decalcomania contacting surface 207 to press upon the decalcomania and the belt which supports the same, pressing downwardly until the belt 62 (each group of belt strands being considered to constitute a belt) has been forced within the grooves of the table 64, in which there is one groove for each of the strands constituting a belt. Thus it will appear that the decalcomania will be forced into contact with the surface 65 (upper) of the dividing strips between the grooves. Firm contact between the belt surface area 201 and the decalcomania expels air and moisture thereby raising the degree of surface tension between these elements to a point sufficiently great to cause the decalcomania to adhere to the surface area 201 of the head. It may be here noted that the sponge rubber pad 200 together with the yieldable pressure of the spring 206 effects the aforementioned pressure upon the decalcomania rather than a precise mechanical movement of the parts concerned.

The sponge rubber pad 202 and the plate 200 to which the pad is secured are given lateral stability by means of a guide rod 3I0 the upper end of which is free to move through an opening in the plate I80 when firm pressure is placed upon a decalcomania. Naturally the apparent length of the stem I98" is fore-shortened, that is, the pad area 201 is moved closer to the plate I80 when pressure is placed upon it and this condition would cause the perforated belt 208 to become loose if it were not for the fact that the rollers I86, to which the ends of the belt 208 are secured, are under constant tension of spring 2I0 and 1381108 wind-up any slack that may develop in the belt 208.

Continued movement of the cam 250 causes cam face 9-72 to lift the head I60 and associated parts so that the head lifts from a point at which the belt 62 is under pressure thereby and the point of head elevation thereby attained is held during the interval that the cam 222 moves from maximum throw to minimum throw. However, as pressure of the cam 222 is eased, the spring 240 forces the rack 234 to return toward its point of beginning and therefore reverses the previous movement of shaft I 38, arm I68, and head I60 and in so doing causes the head to move laterally to point in vertical alignment with its point of beginning. As cam face c--e passes under the roller 268, the shaftand associated parts includtni ing the head are moved downwardly under the combined influences of gravity and the urging of the distended spring 290 thereby bringing the pad area I07 with the decalcomania thereon into firm contact with the surface of a bottle or other object I62.

After completion of the transfer-head lift effected by operation of cam surface gh, it is to be noted that the decalcomania adhering to the area 201 is slid by lateral movement from the paper backing which previously supported it, and this movement is accomplished by reason of the fact that adhesion to the area 201 is of greater tenacity than that offered by the largely dissolved gum previously used to hold the decalcomania to its backing, for when wet and in fact partially dissolved, the gum in effect offers a vehicle to expedite lateral movement of the decalcomania, for in being slid laterally natural air pressure upon the parts is of no concern, for in this case conditions of air pressure are not being disturbed, as would be the case if the decalcomania were moved upwardly or lifted from its backing.

After being brought into physical contact with the bottle I62, the resiliency previously noted in the parts immediately associated with the contact area 201, is again brought into play for it is now necessary that the pad area 26! give up the decalcomania it has carried and that the same be deposited upon the bottle. With the table I64 placed in properly adjusted height in relation to the head I60 considering the ware to be decorated by the decalcomania, contact by the pad 202 upon the object I62 will place the decalcomania thereon, first in gentle contact or pressure and then with increasing pressure as the object I62 gradually displaces normal ex tended position of the pad 202, for previously stated the pad is accommodated in relative upward movement by the movable stem I98" although such movement is resisted by the spring 206 and thereby forces the pad and belt 268 into such firm contact with the object I62 as to cause the same to literally mould itself to the contour of the object I62,

The fact that the pad 202 under pressure of the spring 206 follows the contour of the object I62 is of greatvalue and convenience for it enables decalcomanias to be afiixed to objects having a frosted or etched type of surface, and including surfaces which carry raised letters or other indicia, and including surfaces which are either concave and/0r convex, or concavo-convex when viewed in the same plane or as an undulating surface. Naturally the above mentioned types of contour must be within limits otherwise a pad having modified characteristics would have to be employed, but otherwise the application would not be disturbed in principle or in fact.

Upward movement of the head is accomplished as mentioned in the beginning of this description, and because of the fact that the decalcomania still has a small quantity of gum adhering thereto, and because the pad and belt 208 progressively fold a decalcomania arcuately over a convex surface (the most usual type) all air is naturally expelled from between the decalcomania and the surface to which it is affixed, thereby firmly securing the same in position. Lifting of the pad area 201 does not disturb the decalcomania for by the time spring and pad pressure is eased, air will flow between the parts concerned and entering through the minute apertures in the belt 208 will destroy any vacuum created by the closely related surface relations between the belt and decalcomania previously existing.

Upon partially lifting the head I60, the control rod 218 may be pulled outwardly to disconnect the clutch 2'") thereby bringing the machine to rest pending other and like operations.

It is believed that from the foregoing description it will be clearly apparent that I have provided a simple, easily used and novel decalcomania and/or label transferring machine, however;

It would appear obvious that various changes and modifications and variations may be made in practicing the invention in departure from the particular showing of the drawings, and description as given, without however, departing from the true spirit of the invention as defined by the scope of the appended claims which form the true measure of this invention.
