Specification of Letters Patent.

Patented Sept. a, 1917.

Application filed October 6, 1913. Serial No. 793,512.

To all whom t may concern:

Be it known that I, Lucius B. WEY- Mourir, of Hyde Park, in the county of Suffolk and State of Massachusetts, have 1nvented certain new and useful Improvements in Machines for Applying Metallic Leaf, of which the following is a specification.

My invention has reference to improvements in machines for applying metallic leaf to articles, particularly book covers, preparatory to the operation thereon of the stamping press.

The objects of the invention are to provide an efficient machine which may be readily adjusted to automatically and in one operation deposit strips of metallic leaf, on the article to be ornamented, of any desired number, widths,lengths and in any desired positions. Other objects of the invention will appear from the following description.

The invention consists in the means for automatically controlling the operation of a series of metallic leaf applicators and further consists in such other novel features of construction, operation and combination of parts as shall hereinafter be more fully described and pointed out in the claims.

Like reference characters designate corresponding parts throughout.

In the frame 10 of the machine is the opening 11, the top of which is partially closed by the stationary bed plate or table 12 integral with said frame. Within said opening is the reciprocating carriage 13 supported and guided by the track 14, secured to the underside of said table, and the tracks 15, secured to said frame, which are engaged by flanged wheels 16 journaled on pins carried by said carriage. The latter is provided with the upright 17 from which and firmly secured thereto project transve'sely to and above said table the cylindrica supporting rod 18 the ia er Uri in0 bracket 19, the rod 1.9i, the Ibrlcket 2](lpangd the bracket 2l.

Excepting the variation in the width of the package roll holders 22, they and also the means connecting them with the supporting rod 18 are identical so that a description of one of the package roll holders and its connecting mechanism will suflice for all. Upon the rod 18 is placed the sleeve 23 provided with flanges 24L at its. ends, which is secured in any desired position on said rod by the set screw 25. Pivoted on said sleeve, between its flanges, is the lever 26 and formed on the end of the arm 27 of said lever is the lug 28 provided with the leaf spring 28a. Detachably secured to said i lug is the package roll holder 22 by means of the stud 29 projecting from said holder through suitable apertures in said lug and said spring and provided at its end with a nut 30.

The package roll holder is provided with the fork 31 between which is supported on the detachable piu 32 the package roll 33, and the pressure applicator which in the present instance is in the form of a pressure roller 34 j ournaled on the pin 35 extending through the ends thereof. The arm 36 of the lever 26 extends uprightly' and in order to secure longitudinal adjustment of said arm it is made in two parts, the upper part being threaded into the other at 37.

The arm 3G bears against the adjustable stop bar 40, the ends of which extend through and are guided by a horizontal slot 11 in each of the projections 42 and 43 at the ends of the bracket 2l. Extending through and guided by apertures in the ends of said projections are set screws la which are threaded through the ends of said stopbar and engage blocks 45. The latter eX- tend through and are guided by the slots 41 and their forward movement is limited by the pads 48 at the forward ends of said slots. Connecting said blocks with the shaft 50 journaled in the ends of the bracket 21 are the two sets of toggles 51 which consist of arms 52 fixed to said shaft and links 53 connecting said arms with the blocks 4:5. One end of the shaft extends through the upright 17 and on said end is fixed the gear 541 which is in mesh with the gears 55 and 56 through the idle gear 57 on the stud 59 projecting from said upright. The gea- rs 55 and 56 which are integral, are journaled on the stud 62 projecting from the upright 17 and the portions 63 and 611 respectively of their peripheries are free of teeth. rlhe latter gears are intermittently, driven by the gears 65 and 66 respectively on the outer end of the short shaft 67 extending through and journaled in a suitable bearing in the upright 17. The gears 65 and 66 are respectively provided with oppositely disposed internal ratchet teeth 69 and 70 which are adapted to be engaged by suitable spring actuated pawls 71 and 72 in the short shaft 67. Integral with the inner end of said short shaft is the gear 73 which meshes with the rack 741 extending the length of the table 12 through the intermediate gear 741m. Journaled in the inner end of the shaft 67 is the trunnion 75 on one end of the take-up roller 76 and onA the other end of said roller is the trunnion 77 journaled in the outer end of the bracket 20. The gear 73 is provided with internal ratchet teeth which are engaged by the spring actuated pawl 80 in the trunnion 75.

Extending at a suitable height above the table 12 is the form supporting bed 85 provided with supporting posts 86 bolted to the frame of the machine. Said form supporting bed consists of bars 87 provided with U-shaped grooves 88 and end plates 89. ithin the grooves 88 are supported the longitudinal sides of the form frame 90 which consists of two members having overlapping tongues 91 yand said members are held stationary in their bed by the set screws 92. Extending over the ends of said frame are the clamping bars 95 the under surfaces of which and the top surfaces of the ends of said frame are vcoated with felt or other suitable material between which are clamped by the 'set screws96 any desired number of plates 97 which are adapted to be engaged by beveled surfaces 98 on the ends of the arms 36 of the package roll holder lever 26. The beveled surfaces 98 may also engage adjustable platesl 99 held by set screws 100 in grooves on the bottom of hangers 102. As many of the latter as may be desired are suspended from the rod 103 and detachably secured thereto by set screws 104C. The rod 103`is'supported at its ends in brackets 105 secured longitudinally adjustable to the bars 87 of the form supporting bed 85.

In the frame 10 of the machine is journaled the main shaft 110 which is driven by the pulley 111 through the clutch 112. On said shaft are fixed corresponding gears 113, which mesh with the gears 111 and through the idlers 115 mesh with the gears 116. The gears 1141 and 116 are j ournaled on rods 114 and 116 respectively connecting the forked elbow levers 1187 118 pivoted on the shaft 110 astraddle the gears 113, 113. On each of said elbow levers is a downwardly pro j-ecting arm 119 which is connected to the rod 120 through the links 121. Said rod er tends through and is guided by slots 122 m the posts 123 secured to the frame and at the center of said rod is suspended a weight 124. The gears 111 and 116 alternately mesh with the racks 125 secured to the under side of the 4 carriage 13. Projecting downwardlyfrom said carriage, near its front end, is a stud 126 provided with a beveled surface 127 and adjustably secured to the slotted elongated bar 128 secured to the rear of said carriage is the downwardly projecting stud 129 provided with a beveled surface130.

r1`hel hub of the package roll holder lever is connected to the pressure roller 135, adapted to engage the take-up roller 76, by the link 136 extending over the rod 19a and provided with an adjusting screw 138. Secured to said hub is the downwardly projecting cylinder 139, extending into which is the spring pressed plunger 140 limited in its downward movement by the shoulder' 1411 thereon engaging the corresponding shoulder on the sleeve 113 threaded on the end of saideylinder. The end of said plunger is provided with the gripping plate 1441. Projecting from the top of said hub is the rod 1415 on which is the adjustable weight 1&6.

r1`he machine may be operated as follows The article to be ornamented C is placed on the table 12, against the guides 150 and' 151, secured to the top of said table, either by a suitable feeding mechanism or manually. As the operations necessary for applying all the strips of metallic leaf are the same, a description of the operations necessary for applying only one strip of metallic leaf will suffice for all. The lever 26 with the package roll holder 22 containing the desired width roll 33 of metallic leaf is placed on the supporting rod 18 in line with the portion of the surface of the book cover where the metallic strip is to be deposited. The carriage 13 is then moved forward until the center of the pressure roller 34 is directly above the line wherethe strip to be applied is to end. In turn a plate 97 is clamped in the front end of the form frame 90 with its inner end up to the'end 98 of the lever 26. The carriage is then moved to the limit of its back stroke. The paper strip is in turn passed from the pressure iso roller 34, between the gripping bracket 19 and gripping plate 144,between the takeup roller 76 and the pressure roller 135 and pulled into the tray 160 carried by the bracket 20, until the end of the metallic leaf is directly in line with the center of said pressure roller 34. It is to be understood that all the package rolls of metallic leaf may be applied to the machine before the form is adjusted and during the above described forward movement of the carriage the form is adjusted for them all, so that now no furtheradjustment is necessary, and all that is necessary to deposit the strips of leaf is to apply power to the shaft 110. As the carriage 13 is moved to the limit of its back stroke the beveled surface 127 will en- 'gage the rod 114a forcing the gears 114 into mesh with the racks 125. The rotation of the gears 114 will, through the racks 125, now force the carriage 13 on its forward stroke. During the latter stroke of the carriage the gears 114 will be sustained in mesh with the racks 125 by the weight 124 through their connecting mechanism. During the forward movement of the carriage, as the end 9S of a lever 26 passes the end of its plate 97, its pressure roller 34 is pressed down on to the book cover by gravity of the weight 146, the pressure roller will then be rotated by contact with the book cover until it is moved up out of contact by the beveled surface 98 engaging its plate 97 at the front end of the form. When the strip or strips which extend the farthest forward have been deposited the beveled surface 130 on the stud 129 engages the rod 116a which rocks the elbow levers 18 thereby disengaging the gears 114 from the racks 125 and engaging the gears 116 with said racks. As the gears 116 are driven through the idlers 115 by the gears 113 which are continually rotating in the same direction, the gears 116 will be rotated in an opposite direction to the gears 114 which will force'the carriage 13 on its back or return stroke and the gears 116 will be held in mesh with the racks 125 by the weight 124. lt is to be noted that the shaft 110 continually rotates in the same direction and through the mechanism connecting it with the carriage 13, the latter will be automatically reciprocated, the length of said reciprocation depending on the distance the studs 129 and 126 are apart. As the stud 129 is adjustable said distance maybe varied as'desired.

When the pressure roller 34 is in contact with the article the pressure roller 135 will hold the paper strip in contact with the take-up roller 76 and the gripping plate 144 will be out of contact with said strip allowing the take-up roller by rotating to remove the paper strip from the metallic leaf as the latter is applied. As each of the levers 26 is tilted to move the pressure roller 34 out of contact with the article to be ornamented the adjusting screw 138 will engage the rod 19a which will swing the pressure roller 135 away from said take up roller and gripping plate 144 will be moved down to coperate with the gripping bracket 19 to grip the paper strip. This is an important feature, for if the paper were not gripped it might adhere to the take-,up roller and thereby unwind the package roll or it might drop down between the take-up roller and the pressure roller.

During the forward stroke of said carriage the take-up roller 76, which is common to all the paper strips, is rotated but during the return stroke of said carriage said takeup roller does not rotate, this is due to the ratchet and pawl connection with its driving gear 73 driven by the rack 74. At the start of the return stroke of the carriage 13 the rotation of the short shaft 67 through the gear 73 74a and rack 74 will rotate the gear 65 through their ratchet and pawl connection which will rotate the shaft 50 through their connecting chain of reducing gears until the toggles 51 are moved from the position shown in Fig. 1 to the position shown in Fig. 6, when the shaft 50 will come to rest due to the lack of teeth on the portion 63 of the gear 65. This straightening of the toggles will lift the pressure rollers 34 through the connecting mechanism away from the article on which the strips of metallic leaf have been deposited. At the start of the forward stroke of the carriage the shaft 50 will be rotated by the shaft 67 through their connecting chain of gears, until the toggles have returned to their initial position due to the lack of teeth on the portion 64 of the gear 66 allowing the pressure rollers 34 to operate upon the next article except so far as they are limited by the form plates 97.

lt is to be undefstood that after the machine is started it will operate wholly auto matically and it is only necessary to feed each article to be ornamented onto the table and at the completion of the forward stroke of the carriage the desired amount of metallic leaf will be deposited, then the article is removed from the table during the return stroke of the carriage and a new one is placed on the table by the time the carriage has moved forward sufficiently for the pressure rollers to operate.

The downward movement of the pressure 'rollers 34 is limited by the stop bar 40 which may be varied by manipulating the screws 44. It may be desired to vary the length of the form 90 and this is accomplished by loosening the set screws 92 and sliding the two members of the form toward or away from each other. The swivel connection of the package roll and pressure roller holder 22 with its supporting lever 26 will allow said pressure roller to adjust itself to any irregularity of the surface of the article to be ornamented.

When it is desired to lay two or more strips in the same line but some distance apart the adjustable plates 99 may be einployed as hereinbefoi'e described.

Vhile I have shown but one form of my invention, it is to be understood that this form is but one of many that might be employed and still be Within the scope of the yfollowing claims.
