Application August 12, 1949, SerialNo. 109,893
9 Claims.
This inventionV relates to an automatic foilfeedingmechanism for stamping machines such as are used for branding gold letters into the surface of articles made of leather or other material.
In suchstamping machines, particularly ofthe small manually operated type, a need has existed.
for an automatic foil-feeding mechanism which would be inexpensive, rugged and easily operated by the relatively unskilled operator by whom such machines are usually manipulated.
In the present invention, a frame is mounted on the movable arm and pallet structure of astamping machine of the type as `described and claimed in my `copending application Ser. No. 771,483, filed August 30, 1947, for Stamping Machines, now Patent No. 2,591,369. This frame carries a spool of gold leaf or other printing foi1 machine in a position to be engaged by the feeding mechanism as the arm and pallet structure is brought into the printing position.
Thevarious novel aspects of this invention Will be best understood from the following description of an exemplication thereof, reference being had to the accompanying drawingswherein:
Fig; 1 is a side elevation, with a portion of the handle broken away, of one form of the novel foil-feeding mechanism incorporated in a stamping machine;
Fig. 2 is an enlarged fragmentary prespective view showing the relationship between the ad'- justa'ble detent means and driving ratchetl on the driving roller of the feeding mechanism;
Fig. 3 is a top view of the machine as shown in Fig. 1;
Fig. 4 is-a View of the other side of the machine from thatshown in Fig. l;
Fig. 5 is a fragmentary View, taken along line 5-5 of Fig. 3, `showing the spring bias structure on the feeding rolls; and
Fig. 6 is a fragmentary view of the top of the zev tened upon the base plate 2, and a pair of upstanding side arms 5. A shaft 6 is rotatably mounted between thev arms 5 by pins 'I received in corresponding bores in the arms 5. The shaft 6 carries an arm y8 whichchas formed thereon a branch arm 9 carrying a pallet I rigidly secured thereto. The arm 8 is extended to form a handle I I, whereby the entire arm assembly carrying the pallet IIJ with it may bev rotated about the pins 1.
In order to provide a printing surface at the proper height, a pedestal I2 is also welded or otherwise secured to the base plate I andis in a location preferably directly below the pallet Il) in its stamping position. For the purpose of supporting relatively extended articles, a supporting plate memberv I3 is adapted to be placed upon the pedestal I2 andretained in proper position by pins I4 carried by the pedestal I2 and received into corresponding holes in the` plate I 3. The outer end of the plate, I3 is supported by a pair of legs I5 secured to the plate I3 and resting on the sub base KI. To retain an article to be stamped, the plate I3 is provided with a spring and thus cooperates with the block 2| to retain the guide I9 in position. An end guide block 23 may be clipped into position at any desired location on the guide I9 by means of a spring clip 24 secured to the block |23. The article to be stamped may have one edge bearing against the guide I9 and an adjacent edge against the guide block '23 whereby said article is correctly oriented on the plate I3 so as to be stamped accurately.
The pallet I0 consists of a type-holding block 25 rigidly secured to the outer end of arm Si. The block 25 is formed as described and claimed in my copending application identified above to retain the type II in place by means of a clamping bar 26 and to center the type II by means of a pair of `centering blocks 21.
In order to provide the proper surface beneath the stamping area, the plate I3 has inserted therein an impression pad 6'5, which may be made of;l suitable resilient material such as several layers of cardboard. Heretofore, relatively extended impression pads have been used, necessitating a removal of the guide I 9 when replacing the impression pad when it has become worn. This has further necessitated the resetting of the guide I9 and other gauge members which is quite undesirable. In the present construction the size of the impression pad is limited in its dimensions to substantially the maximum area which may be covered by the type I'I. Further, the impression pad 65 is received in an opening 69 in the plate I3 below the pallet I0. This plate I3 is also cut away at one side of the opening 66 at 61 in order that the impression pad 65 may readily be removed and replaced. A pin 13, secured to the rule and guide I9, projects into a slot 'I4 in the plate I3 so that the rule and guide I9 and its projecting arms 'III and 'I2 are limited in their possible positions of adjustment so as not to overlap the opening 66 or come into contact with the feed mechanism. The arms TI and 'I2 prevent the article being stamped from overriding the rule and guide I9. Due to the above structure, once the guide I9 has been set and the impression pad 65 thereafter needs to be replaced, the guide I9 is not disturbed while the old pad is removed and a new pad inserted.
Before operating on the work in devices of this kind, it is usually desirable to heat the type to a relatively high temperature to secure the proper transfer of the gold leaf or other printing foil to the article to be stamped. For this purpose the block 25 has contained within it a heating element supplied with heating current through a cable 28 extending from any suitable and wellknown adjustable current controlling means 29 which has its input current supplied from a cable 30.
The printing foils used in machines of this kind usually consist of a strip of paper or plastic coated on one side with a layer of gold leaf or a deposit of metal powder. Such a foil is indicated by the dot-dash line 3| in Fig. 1 and more directly at 3| in Fig. 3. As shown in Fig. l, this foil must be interposed between the face of the type I'I and the surface of the pad 65 with the coated side of the foil next to the pad 65 whereby the coating is transferred by the heated type I1 to the article to be stamped. In order to support and feed the foil 3I, a frame 32, made of an elongated metal bar bent into the desired shape, is pivoted at its ends 33 to the side walls 34 of a frame 35 rigidly secured to the shaft 6. Thus the frame 35 moves as a unit with the combined handle and pallet structure. The outer central portion of the frame 32 snaps under and is retained in position by a spring pressed detent 36 mounted on the arm 8 near the handle I I. The spring is shown at 31 in Fig. l. The detent may be released from the frame 32 by a button 38. At the forward bend of the frame 32 is mounted a guiding plate 32a over which the foil SI passes. This guiding plate also serves to brace and strengthen frame 32.
Two corrugated feeding rollers 39 and 40 are rotatably mounted on the side walls 34 of the rrame 35. The foil 3I is adapted to be received between the feeding rollers to be advanced thereny. As will be seen most clearly in Fig. 4, the corrugations of the smaller upper roller 39 engage in the corrugations in the larger roller 40 in the manner of a pair of gears so that rotation of the roller 40 positively turns the roller 39. The foil 3l engaged by the corrugations is likewise positively advanced by such rotation. In order to accommodate different thicknesses of foil,
the openings 68 in the plates 34 in which the shaft 69 of the roller 39 is received are slightly larger than the shaft itself as shown in Fig. 4. The two rollers 39 and 40 are resiliently urged toward each other by a pair of spring clips 'I9 which engages the opposite end of shafts 69 and 4I of the rollers 39 and 40. This structure at one of the rolls is shown most clearly in Fig. 5. This spring bias structure not only enables the device to accommodate foils of different thicknesses but also takes up any wear so that the feeding rollers 39 and 40 always rmly engage and feed the foil 3|.
In order to produce the desired rotation of roller 40, that roller has the shaft 4I, by which it is mounted in one of the side walls 34, extending through said side wall and provided with a ratchet plate 42. The shaft 4I may be provided with a head 4Ia for manual rotation of the roller 40. The ratchet plate 42 is normally held in position by means of a spring biased detent 43 pivoted to the side arm 34 and biased by a spring 43a. This arrangement prevents a counter-clockwise rotation of the feeding rollers 39 and 40 as viewed in Fig. l and thus prevents a retrograde motion of the foil 3|. The feeding motion of roller 40 is produced by the engagementvof the ratchet plate 42 with a detent pawl 44 pivotally mounted by a pin 45 in one of the side arms 5 of the frame 3. The detent pawl 44 is biased upwardly by a spring 46 coiled around the pin 45. The pawl 44 is provided with a side plate 41 adapted to engage a stop 48 as the pawl 44 moves upwardly by the spring 46 when the arm II is moved upwardly and carries the frame 35 together with the ratchet 42 away from the pawl 44. The stop 48 fixes the level at which the ratchet 42 stops in such upward movement.
The stop 48 is mounted at the outer end of an arm 49 pivoted by pin 50 to one of said side arms 5. The arm 49 carries at its upper end an arm 5I so that the position of said arm and of its stop 48 may be adjusted. The arm 49 is held in any one of a plurality of positions by having a reduced section 52 thereof receivable in notches formed in a plate 53 secured to said side arm 5.
Upon the side of the frame 32 adjacent its upper ends are fastened two arms 54 and 55 adapted to receive a rod 56 having one end threaded into a corresponding threaded opening 51 in'arm 55. The'other end of the rod 56 has a head 58 whereby the rod may be turned into position. The rod 56 is adapted to pass through and support a spool 60 upon which is wound the printing foil 3I. The rod 56 is made removable as above described so that any desired printing foil may be placed in the machine. In order to exert a tension on the foil 3| so as to keep it in close contact with the type II, a friction brake arm 6I, held in place by set screw 59, is mounted on the arm 55 so that its outer end bears against an end plate 62 of the spool 50. The degree of pressure between the brake arm 6I and the end plate 62 may be regulated by a screw 63 threaded through the arm 55. A spring 64 interposed between the head of screw 63 and arm 55 tends to prevent screw 63 from turning unless manipulated by the operator. 4
The operation of the machine is as follows. The button 38 is pulled upward to release the frame 32 from the handle II and arm 8. Thereupon said arm and handle may be rotated upwardly, leaving the frame 32 resting on the plate I3. This exposes the pallet II] upon which .the
type Il may then be assembled as described in myy above-identified copending application. .A selected spool of printing foil may then be inserted between the arms 5.5i and 55 and secured in place. At this point, the frame 3.2 may be swung up and snapped in position under Athedetent 35. Thereupon the end of the foil 3 I- ispulled over the guide plate 32a, over the face of thety-pe El and then inserted between the feeding rollers 3.9 and 4Q.. A few turns of the head lila will pull the foil through the rollers and take up any slack in the foil against the tension of the brake arm (il. The cable 3i) is then energized and the current .controlling means 29 set for the proper degree ofheating of the type. When the proper temperature has been reached, the stamping may begin. The article to be stamped is suitably fixed on .the plate I3 and the handle il is lowered to bring the type i] and foil 3l into engagement with that article. Just prior to the time the foil 3|. engages the article, the ratchet i2 comesinto position where the pawl et engages one of the ratchet teeth. Further rotation of the arm 8 forces the pawl it downward against Vthe action of spring tt, and, at the same time, the pavvl lli rotates the ratchet plate t2 which turns the roller 453, advancing a fresh portion of the foil 3l over the type l'l. This motion of the ratchet, feeding roller and foil ceases just as the coil comes into contact with the article to be stamped and further pressure on the handle Il completes the stamping operation. When the handle ii is subsequently raised, the ratchet i2 rises to permit the pawl @il to rise to the level at which it is stopped by the stop 118.
It will be noted that the higher the pawl llrises, the sooner it will engage the ratchet t2 on the next stamping stroke. This means that the pavvl 44 will engage a lower tooth of the pawl 42 and thus produce a greater rotation of the collar 4G and a greater feeding of the foil 3 l. Thus the position of adjustment cf the arm 49 and its stop 118 adjusts the amount by which the foil 3| is fed on each stroke. This permits the feeding of the foil Si to be matched to the size of type used for maximum utilization of the foil. it should also be noted that, by feeding a fresh area of foil onto the type immediately prior to the imposition of stamping pressure, an exact uniformity of stamping conditions is obtained irrespective of the interval of time elapsing between printing strokes.
This completes the description of the above embodiment of the invention in which many equivalents of the details described will suggest themselves to those skilled in the art.
