AUTOMATIC SELF-DRIVEN FILLET-MACHINE FOR APPLYING METALLIC LEAF.

Application led March'lS, 1915.

To all ywhom it may concern.'

Be it known that I, ADELBERT S. JAQUITH, a citizen cf the United States, and resident of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Automatic Self-Driven Fillet-Machines for Applying Metallic Leaf, of which the following is a specification.

This invention relates to machines for transferring from a package roll to a fillet roll, a fillet of metallic leaf, such as gold, silver. etc., the fillet adhering to the fillet roll and being transferable thereby to a surface to be ornamented.

The invention is embodied in a machine in which the portion of the fillet passing to the fillet roll is supported by and moves on a feeding member such as a rotary drum, until it is taken up by the fillet roll, the feeding member being yieldingly supported in a given normal position and shiftable therefrom by pressure of the fillet roll on the feeding member, such depression causing a fillet-feeding movement to be imparted to the feeding member by a suitable power mechanism or motor, the organization being such that the feeding movement of the feeding member is automatically stopped when the fillet roll is removed and the feeding member returns automatically to its normal position.

The invention is also embodied in various improvements relating to the means for rotatably confining the package roll under tension, to means for feeding from the machine the paper strip which separates the convolutions of the fillet. and to other' parts of the machine.

Of the accompanying drawings forming a part of this specification: Figure 1 represents a top plan view of a machine embodying my invention, the cover hereinafter referred to being removed: Fig. 2 represents a section on line 2 2 of Fig. 1, showing the cover in place: Fi g. 3 represents a section on line 3*?) of Fig. 1: Fig. 4 represents a section on line 4 4 of Fig. 1; Fig. 5 represents a section on line 5 5 of Fig. 1; Fig. 6 represents a section on line 6 6 of Fig. 1: Fig. T represents a section on line 7 7 of Fig. 1; Fig. 8 represents a side view of a aortion of the drum and the fillet roll applie thereto; Fig. 9 represents a side elevation of the Specification of Letters Patent.

machine, the cover being shown in section; Figs. 10, 11, 12 and 13 represent fragmentary views illustrating the means for supporting the pressure roll hereinafter described.

The same reference characters indicate the same or similar parts in all the views.

The machine of my invention includes a motor which is preferably spring driven. To illustrate the invention I have shown a spring motor of the type employed to drive the record cylinder of a phonograph, said motor developing a relatively low degree of power and being adapted to be quickly stopped by the application of a relatively light motion-resisting force.

The motor illustrated is mounted on a base 9, forming a part of the general supporting frame. The motor includes a series of springs 10 (Figs. 2 and 5) inclosed in a case 11, means including a crank shaft 12 having a crank 13 for winding the springs, and a train of shafts and gearing driven by the springs, the several shafts being `journaled in bearings supported on the base as shown. Said train includes a short shaft 14 (Figs. 1 and 3) having a small gear 15 driven by the springs through the intermediate gearing shown, and a larger gear 16. In a motor of this type the speed is controlled by governor and brake mechanism acting through a shaft 18 having a gear 19 meshing with the gear 16. said shaft having a brake flange 35 against which a brake shoe is pressed by the centrifugally operated means commonly employed, and shown by Figs. 1, 5 and 6.

The mechanism thus far briefly described is so well known in phonograph motors that a description of the connections between the small gear 15 of the shaft 14 and the motor springs is not deemed essential. The shaft 14 has another small gear 20 which has been added by me to the described motor mechanism. The gear 20 meshes with a larger gear 25 which is attached to the shaft 26 (Figs. 2 and 7) of a feeding member` which as here shown is a traction roll or drum 27. over which a fillet of metallic leaf is passed to be taken up by a hand-operated fillet roll or a gilding die, as hereinafter described. The drum shaft 26 is journaled in bearings formed in an oscillatory or shiftable drum-supporting lever, the form of which is clearly shown by dotted lines in Fig. 1, said lever being composed of two members 28, 28, a neck 28h connecting said members, and an extension 28 of the member Q8. The members 2S, 28 are fulcrumed at 29, 29, on upright frame members 30, 31, formed on the base 9, the alined fulcrums being arranged in alinement with the shaft 14, as indicated by Fig. 7. The drum 27 is normally supported in a given position by the said supporting lever and by a spring 32 acting thereon, and is shiftable therefrom bv downward pressure on its upper surface without disturbance of the engagement of the gears 20 and the gear being shiftable with the drum and remaining in engagement with the gear 20 during its shifting movements. The drum-supporting lever has a two-part arm formed by the portions of the membersA 28, 2S at one side of the axis of oscillation. said members supporting the shaft 26 and drum 2". and another arm formed by the portions of said members at the opposite side of said axis, and by the extension QSC. The drum supporting` lever is subjected to the biasing action of a spring 32 (Fig. T) which presses downwardly on the extension 28 of said lever and thus holds the two-part arm cf said lever and the drum supported thereby vieldingly raised, the spring 32 being snfliciently strong to support the drum in a raised position, so that the drum is depressible or shiftable by downward pressure exerted upon it, the lever being swung on its fulcrum axis b y the depression of the drum to raise its spring-pressed arm.

The frame member 31 has a slot 34 through which the shaft 26 passes. said slot permitting the shaft and roll to move vertically. The downward movement of the drum 2T. cause-d by the downward pressure of a fillet roll on the highest portion of its lperiphery. is utilized through the means next described to start the motor and cause the rotation of the drum. The brake flange (Figs. l and 6) is connected with the shaft 1S to rotate with it, but as here shown is movable lengthwise of the shaft by the action of governor weights 36 carried by springs 3T. which are attachedv at their respective ends to a collar 38 fast on the shaft 1S and a collar 39 fast on a sleeve 40 formed with the flange 35.

41 (Figs. 1. 5 and G) represents a brake shoe mounted on the swinging end of an oscillating carrier 42 which is pivoted at 43 (Fig. (3) and normally holds the shoe 41 against one side ef the flange 35. so that the shoe prevents rotation of the said flange and of the shaft 18. The brake shoe carrier #l2 is connected by a rod 4l with one arm of a bell crank lever 45 (Fig. 6) Which is fulcrumed at 46 and has on its other arm an extension 45HL which extends through a slot i? in the frame member' 31 and enters a slot 48 (Fig. 7) in the spring-pressed portion '28 of the drum-supporting lever.

The described parts are so arranged that a slight depression of the drum 27 will raise the lever extension 28C sufficiently to cause the bell crank lever 45 and rod #il to swing the shoe carrier l2 away from the flange 35, and thus permit the rotation of the shaft f8. It follows, therefore. that the depression of the drum starts the motor and causes the rotation of the drum. Upon the removal -of downward pressure from the drum, the spring 32 acts to raise the drum and at the same time set the brake shoe against the fiange 35, thus stopping the motor and the drum. Then the motor is running, the governor acts to move the fiange 35 toward the brake shoe and into suflicient contact therewith to reduce the speed in it becomes more than normal. As hereinbefore stated, the governor is not of itself a part of my invention. In fact, the governor illustrated may be dispensed with, the flange being attached immovably to the shaft 1S in case automatic speed regulation is not desired.

The fillet 5() of metalli." leaf. shown by broken lines in Figs. T and 8. is wound with a paper strip .31 on a core (Fig. (i). the convolutions of the fillet and strip alternating. and the whole constituting a package roll designated by the reference p in Figs. 5 and 6. Said package roll is rotatably sup ported between a fixed head 53 on the frame member 31 formed to bear on one side of the core 52. and a movable head 5l formed to bear on the opposite side of said core, said hea-ds having bosses 55 entering the bore of the core. The movable head 5l is attached to rods 56 which are slidable in guides in the frame member 30, and are connected by a cross bar 5T having a knob or handle A spring 59 interposed bctween the frame member 3() which constitutes a fixed spring abutment and the head 54. presses thelatter against the core. The fixed head 53 andthe spring abutment portion of the fixed frame member 30 are separated b v a relatively wide invariable space containing the movable head. the spring, and a package roll. The heads .33 and 54 are adapted to confine package rolls y) of various widths, the spring 59 yielding to accommodate the width of the roll, and being of tapering or conical helical form, so that its convolutions nest into each other when the spring is compressed. The tension or pres sure ofi the spring on the movable head 54 is therefore automatically regulated according to the width of the package roll. lf the roll is relatively narrow or of minimum wid-th, it requires less spring pressure than a wider roll. The conical form of the spring enables the spring to be compressed with a constantly increasing pressure and without interference of its convolutions with each other. until the spring assumes approximately a fiat spiral form with all its convolutions in close proximity to the fixed abutment. The conical spring therefore enables a much Wider roll to be employed. Without adjustment of the abutment. than would be possible if the spring were helical with all its convolutions of the same diameter. The pressure of the conical spring is greater on a relatively wide roll than on a roll of minimum Width, there being no limitation of the spring pressure by interference of the convolutions .vith each other. The movable head 5-1 is readily displaceable b v the knob or handle 58.

The drum '27 has a peripheral face 27 of yielding frictional material. such felt. leather. etc. Yhen the fillet roll (31 carried by the usual shank G3 and handle (3l (Figs. S and 9) is pressed downwardly on a fillet 50 resting on the drum.y the pressure causes the rotation of the drum as above stated. and the fillet adheres to the periphery of the roll, which is usuaily heated preparatory to use. the fillet being thus separated from the strip 51, which is carried away by the rotation of the drum. The fillet is subsequently applied as usual by the roll to the surface to be ornamented.

Fig. 6 shows a steady pin 56a attached to the fixed head 53 and passing through an orifice in the movable head 54 to prevent the binding or cramping of the rods 56 in their guides. A pressure roll (i6 bearing loosely on the periphery of the drum holds the strip 51 against a part of said periphery. as shown by Fig. 7, and insures the separation of the strip from the fillet. Said pressure roll has trunnions (i7. (38. which rotate in bearings formed by an inclined recess G9 Fig. 13) in one of the frame members. and b y an inclined slot (Fig. 11) in a plate 71. which is connected bv a hinge 72 with a fixed plate 73 on another frame member. The hinge is inclined. and the trunnion G8 has a groove 74 (Fig. 12) engaging the plate 71 to prevent separation of the trunnion GS therefrom. as shown by Fig. 12. The pressure roll Gti is adapted to be displaced. as shown by Fig. 10. by a swinging movement of the plate 71. W'hen the roll is returned to its operative position, its trunnions are free to slide in the recess 69 and slot 7() toward and from the drum '27. The `iveight of the pressure roll is therefore sufficient to hold it operatively against the strip. no springs being required. The frame members 30 and 31 are provided With flanges 30 and 3la which overhang portions of the drum and are separated by a space vvidc enough to expose the facing 27a. A removable cover 78. fitted at its edges on a seat 31" on the frame member 31, and in a groove 9a in the base S), forms. with said base and frame member. a casing inclosing the motor and the described gearing. It will now be seen that the drum is started by the pressure of the fillet roll against it, and stopped when the pressure is removed. The spring 59 and head 54 exert sufficient pressure on the package roll p to prevent loose rotation thereof, so that the fillet and the paper strip stop instantly when the fillet roll is removed. and are not fed forward by any slight continuation of the rotation of the drum diie to its momentum after the removal of the fillet roll. hence Vthere is no waste of the fillet. The lever extension :28 is preferably provided with a stop stud 28d arranged to abut against a fixed .frame member above it and limit the depression of the drum by the fillet roll. The sliiftable stripand-fillet feeding member or drum 27 may be used with a motor or driving mechanism of any other suitable type and construction. the organization being such that the motor is caused to operate by the shifting of the drum from its normal position. and is auto matically stopped by the return of the drum to its normal position.

As above stated. the casing or cover 7S. the frame base 9. and the frame member 31 entirely inclose the motor and the gearing. To prevent talnpering with the said inclosed mechanism I prefer to secure the cover 78 by practically invisible or secret means, so that the cover can be removed only by an authorized person having knowledge of said means. l have embodied the secret cover-securing means in small pins 80 (Fig. 2), driven into registering holes in the cover 78 and in the seat 31b on the frame member 31. and similar pins 80 driven into registering holes in the cover and in the portion of the base 9 in which the groove 9a is formed. Said pins have a close driving fit in the holes and are so small that their outer ends are practically invisible and can be detected only by a person having knowledge of their location. The pins may be ejected inwardly to release the cover by a small punch driven against their outer ends.

The frame member 31 is preferably formed as an integral part of the base 9, and the frame member' 30 is formed independently and provided With integral flanges 30 and 30d (Figs. 1, 7 and 9), one located behind and the other in front of thel drum 27, as shown by Fig. 7. said flanges abutting against the frame member 30, and being secured thereto by screws 82 (Figs. 1 and 7). The said screws are inserted from the space under the cover 78, so that they are inaccessible when the cover is in place. The detachable frame member 30 is secured to the base by screws 84 (Figs. 1 and 2) inserted in the base and engaged with slotted ears 85 on the member 30, the ears being movable horizontally under the heads of the screws.

One of the fulcrum studs 29 is attached to the frame member 30, as shown by Fig. 2. The drum 27 and its supporting lever are installed before the frame member 30 is located and secured, said member being then moved horizontally inward on the base until its ears engage the screws 84, and its flanges 30c and 30d abut against the frame member 31, the fulcrum stud 29 carried by the member 30 being at the same time engaged with the drum-supporting lever. The screws 82 are then inserted to confine the frame member 30 in place, this being done before the cover 78 is applied and secured. The fiange 80C is provided With an extension 30e (Fig. 7) projecting toward the rear side of the drum and covering the lever portionsl 28, 28@ and 28d. The flange 30d is curved at its upper portion into close proximity to the front side of the drum, the outer side of said flange forming a guide for the paper strip 51.

lt will now be seen that the detachable frame member 30 and its flan es coiiperate with the frame member 3l an the base in forming an inclosure which contains the drum and its shiftable supporting lever, and is interrupted only by an opening exposing only the upper portion of the periphery of the drum. The detachable frame member can only be removed by withdrawing the screws 8:2, and this can be done only when the cover 7 8 is removed, hence the securing of the cover in the manner above described prevents access to the main portion of the drum and to the drum-supporting means.
