MACHINE FOR APPLYING METALLIC LEAF.

Specification of Letters Patent.

Patented Apr. 2, 1918.

Application filed December 5, 1916. Serial No. 135,159.

To all whom it may concern:

Be it known that I, Anne BRooKn, a subject of the King of Great Britain, residing at Glasgow, Scotland, have invented certain new and useful Improvements Relating to Machines for Applying Metallic Leaf, of which the following is a specification,

The present invention, which relates to machines for applying metallic leaf, has reference to improved means for automatically lifting, and (or) transferring and pressing the metallic leaf for ornamentation or other purposes, and is an improvement upon my prior United States invention, Patent No. 1,162,448 issued November 30th, 1915.

In the specification of my prior patent I described a machine into which the leaf was automatically fed and in which the necessary lifting, transferring, and pressing operations were automatically performed by means of an oscillating or reciprocating device which alternated between the leaf and the book or other article to be im pressed.

The present invention consists in providing a. device which is adapted to carry the metallic leaf and the article to be operated on and move them alternately under an impressing device or die, which may be fixed or movable, and which serves both to lift or transfer the leaf and apply it to the article, these operations being automatically performed.

Means, automatically actuated, and substantially described in my said prior specification, may be used to sever portions of the leaf, and same may be placed at any convenient position between the reels of leaf and the feeding mechanism.

The usual greasing device may also be incorporated with the mechanism to insure that the leaf adheres to the lifting device.

In order that the invention may be clearly understood I have hereunto appended explanatory drawings whereon I have shown, by way of illustration or example, a preferred mode of carrying the invention into effect or practice.

On the drawings Figure l is a front elevation of such parts only of the machine as are necessary to explain this invention.

Fig. 2 is a corresponding side elevation.

Fig. 3 is a corresponding plan.

Figs. 4 to 9 are detail views.

The arrangement shown comprises an impressing devlce C and a traveling carriage which is moved backward and forward underneath the impressing device by means of suitable mechanism. The carriage has, on it, two tables, one marked 0 upon which the article to be treated is placed and which may be of substantially the same construction as the table described in the specification of my prior U. S. Patent No. 1,162,448 and a second table 6 over which the leaf is fed. The carriage, which is marked 6 carries also the severing knife 7" and its mechanism, the reels or spools of metallic leaf, and the pulling or feeding device; the knife mechanism, and the spools being arranged on a bracket a at the right hand side of the carriage, Fig. 1, and the pulling or feeding device D being arranged on an extension 6'' at the left hand side of the carriage. The knife and its mechanism may be substan tially the same as that set forth in the specification No. 1,162,448 while the pulling or feeding device may be of essentially the same construction as that set forth in the specification of my co-pending application Serial No. 92137 filed April 19th, 1916.

There may be one or more spools of leaf according to the work to be done and the spool, or spools, is, or are, arranged in the receiver a fitted on the bracket a a shows one of the spools.

The carriage c has rollers e which run upon the surface 1 of the bed B of the machine and this carriage is reeiprocated by means of a rack 71, shown in dotted lines in Fig. 2, which is operated by means of a toothed quadrant i fixed to a shaft j which in its turn, is operated by a pinion j under the action of a rack is connected to a grooved cam Z shown in the detail views, Figs. 7 and 8. In the groove Z of this cam works a pin m projecting from the side of a disk at on the main shaft n which latter is, preferably, driven b a belt pulley E and driven belt I. On t 1e shaft n is a second cam 0 having a groove 0 in which works a pin p on a vertical rod 5 This rod 9 is moved upward and downward in guides g and it operates, through a link f, a toothed sector 9" pivotally mounted on a pin 1' of the frame A. The teeth of this sector mesh with the teeth of a similar sector also marked 1' and also pivotally mounted on a pin r of the frame A and the sectors are adapted to operate links 8. a. so as to raise and lower the impressing device which is guided in its vertical movements by a guide rod 6 working through a guide way in the frame i Now. it is obvious. that. when the shaft It is rotated the cam I will he caused to move backward. and forward thereby reciprocating the rack A and turning the pinion i and quadrant I so as to reciprocate the carriage e and move the tables 6 and 0 alten nately underneath the die block 2* of the impressing device and these movements of the carriage are arranged so as to properly synchronize with the vertical moven'ients of the die block, the cams Z and 0 being groin ed to give the desired movements at the proper times and in the proper sequence.

The operating wheel D of the dcvit't' ii for pulling the paper strip or strips so as to feed the leaf is operated by a long pinion D which is driven by means of shafts 3). i, 3 and gears 6, T. 8. 9, from the main shaft ii. The pinion D is of such length as permits of the full travel of the carriage without the wheel D getting out of gear.

From the shaft 10 of the wheel T) the severing knife is driven by means of gears 12,

shafts

13, 14, and face cam .r. 'l he severing mechanism is shown at Figs-z. i and 5 and, as will he seen, it is similar to that described in my prior specification No. 1,162,448 except that the knife 7" has actuating rod operated by the face cam a). f is a roller over which the strips with the metallic leaf pass, under the knife f. and then over the table a to the pulling device D. There may he any desired mun-- its her of strips used. the rolls for the strips being simply inserted into the receiver frame a fixed on the bracket (4 This frame has grooves 1.5 in its sides and each roll of leaf is secured to a plate 16 which is then dropped into one pair of grooves l-i so that the roll appears as at Fig. 3 which is a plan view of part of the frame which latter also shown in vertical section at Fig. i. To separate the rolls from one another partition plates. as at lT. Fig. i are used and dropped into the grooves 15. In the machine I have only shown two strips of leaf 18. 19, with two winding spools for taking up the paper strips. these spools being indicated at 20, 21. Fig. 1.

The arrangement is. preferably. such that when the table 6 is under the impressing device the latter first descends. contact with, and then lifts up the severed piece. or pieces. of leaf on the table 0" and which it is desired to apply to the article. To do this. at the next forward movement of the carriage, the table 6 is moved froi'n under the impressing device while the table 0 is brought under the impressing device whereupon the latter descends and applies the leaf to the article on the table.

In the arrangement hovvn the article to be treated is placed upon the table c by hand but it may he mechanicall fed thereto in any well known and usual manner, the table being constructed and arranged accordingly.

The cam I. \vhlch is shown in detail at Figs. T and S, has its groove Z of a peculiar shape. the groove being curved at the sides Z Z and straight at the parts F, The circle m Fig. 7. indicates the path of the pin m. of the dish m and the pin. as it travels this patl'i. moves the cam, when it is in the part. Z toward the left and. when it is in the part I". toward the right. hen the pin traverses the curved groove Z the cam is held stationary and consequently the carriage is statioi'iary and thus a pause takes place. during the lifting of the leaf from the table 6 by the die 0, and, when the pin travels the longer curve 1 the earriage is again caused to pause, and this pause takes place when the table 0 is under the die L and the gold leaf is being pressed and blocked upon the article. The reciprocatory action of the cam Z is sufficient to cause the quadrant i' to move the table first toward the right hand. Fig. 2. and from underneath the impressing device. at the same time simultaneously moving the table 0 under the said device. and. then. at the next return movement. to shift the table 1." from under the impressing device and bring the table (1 thereunder. the table 0" and the table 0 being, in this manner. brought alternately underneath the impressing device. It is necessary when the tables are underneath the impressing device and the latter is acting upon the leaf or the article, as the case may be. tha the carriage should be held stationary for a momentary period and this is effected as before stated by the action of the pin "m and the cam grooves Z Z Likewise. it is necessary during the blocking operation that. the aticie should remain in contact with the. article for a short period and this eifreted by the action of the cam 0 whose groove o it will be noticed, Fig. 2, is flattened at its upper part so as to produce the necessary pause in the movement of the die W hile the article is being impressed and blocked the pulling mechanism D comes into operation and effects a feeding movement of the metallic leaf so as to bring a new piece, or pieces, of leaf upon the table in order to be. transferred by the impressing device to the next article.

The severing device f is arranged to act properly in conjunction with the pulling device D this being effected in the manner set forth in my said U. S. specificat ion'Sei-ial No. 92137.

llO

The die block 1 of the impressing device, (7 is greased automatically ll) means of a greasing roller u shown at Fig. '3 and also to an enlarged scale at Fig. 9. This roller is mounted on the upper end of a rod u carried in brackets 11 u. on the rack 11. A spring It acts to force up the rod u and the extent of the upward movement can he regulated by means of the screw out f. livoted on the bracket u" is a catch :1" wh'ch has a downward extension u weighted at N". Ah the carriage travels toward the right hand Fig. 9. the rod u eventually meets a pin a in a bracket 11* on the frame A and strikes thereagainst causing the catch a to swing and disengage the pin of the roller u. whereupon the greasing roller springs upward so as to contact with the underside of the die block 1 and. as the carriage moves along; grease the die hlcelc. When the rod 1/ is free from the pin u it acts automatically to catch the roller u again, while the latter is forced down bv the die block 1.. and hold it in the position shown at F ig. 9.

It is obvious thedetails of construction of the various parts of the mechanism can be altered or modified without departing from the invention.
