BOTTLE-CiP-EKAKING MACHINE.

Application filed J'uly 2 2, 1922. Serial No. 576,743.

' fication.

l The invention relates to a bottle cap making machine, and more particularly to the classof machines for punching and printing milk bottle caps. r

The primary object of the invention is the provision of a machine of this character, wherein strips of paper are properly fed into the same, and subsequently acted upon for the. printing thereof, and finally the caps in the form of disks are cut from the strips, in a continuous operation of the machine, the latter being of novel form, as it comprises but few parts.

Another object of the invention is the provision of a machine of this character, wherein the printing plate or die is inked in a novel manner, and also operated to make the required impression upon the strip fed to the machine, so that the necessary marking is had upon the disks, which are cut from the strip to form the caps for bottles.

A further object of the invention is the provision of amachine of this character, which is extremely simple in construction, thoroughly reliable and G'illCiQIll? in opera tion, strong, durable, and inexpensive to manufacture and install.

lVith these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts, as will be hereinafter fully described,

illustrated in the accompanying drawings, and pointed out in the claims hereunto appended.

In the accompanying drawings:

Figure 1, is a side elevation of the ma chine constructed in accordance with the invention.

Figure 2, is a top plan view thereof.

Figure 3, is a vertical longitudinal sectional view through the machine.

Figure 4, is a sectional view on the. line 14 of Figure 1.

Figure 5, is an end elevation.

Figure 6, is a detail plan view of the ink ing platen, showing fragmentarily by full line and dotted lines the inking device.

Similar reference characters indicate corresponding parts throughout the several views in the drawings. I

Referring to the drawings, in detail, A,

designates generally the supporting frame of the machine, and includes the legs 10, of anydesirable form, for a bed having spaced par allel side rails '11, in which are journaled in any suitable manner the rollers 12, and 13,

respectively, for an. endless conveyor apron or belt 1d, the roller 12, being located at the forward end of the bed, while the roller 13, is removed a distance froni' the rear end thereof. r

immediately beneath the upper stretch .of V

the conveyor apron or belt 14, close to the roller 13, is a printing bed 15, having an adustable upper section 16, to permit the levelling thereof, and this section is provided with a resilient covering 17, to assure tne proper impression from printing mechanism hereinafter fully described Rising from the bed ofthe frame A, of the machine, is stand 18, which is disposed directly over the bed 15, and in this stand is a horizontally arranged inking platen or plate 19, through which Works a printing die 20, carried upon the lower end of a vertical. plunger 21, slidably fitted within the guide ortion 22, ofthe standilS, the 35 plunger 21, being held normally elevated above the printing bed 15, through the medium of-an expansion spring 23, coiled about said plunger and working against the guide portion and the upper striking head 24, on

the {plunger at its upper end.

1/ ounted upon the side rails 11, of the bed of the machine, at the end next to the roller '13, are vertical uprights 25, having at their tops bearmgs 26, inwhich 1s Journaled a cranked shaft 27, the medial crank 28, of which has connected thereto a pitman or connecting rod'29, for acutting punch 30, which i pivotally connected with the itman or rod 29, as at 31, so that on rotation 1 of the shaft 27, the punch 30, will be reciprocated vertically in a guide head 32, the base of the latter being formed with a die 33, for the punch 30, as will be clearly apparent,

so that disks will be cut by the latter when actuated, in the operation of the machine.

On the pltman or rod 29, is a presser arm 84, which acts directly upon the striker head 24. of the plunger 21, so that on rotation of the shaft 27, the latter will be operated to 119 bring the printing plate or die 20, into posi tlon relative to the pr1nt1ng bed 15, for making an impression upon a strip of paper fed therebetween on the conveyor apron or belt 14. r

(lo-acting with the conveyor apron or belt 14, directly over the roller 13, is a feed roller 35, having on the outer end of its shaft a ratchet wheel 36, With which engages a dog or pawl 37, mounted in a rocker lever 38, engaged upon the crank arm 39, at one end of the shaft 27, while engaged with the crank arm 40, at the other end of said shaft is a connecting rod 41, pivoted to a bell-crank lever 42, mounted on one side rail 11, of the bed of the machine, and this bell-crank lever has also connected therewith an arm 43,.

which likewise is pivoted to a second bellcrank lever 44, mounted upon the inking plate or platen 19, the said lever 44, being fitted with an inking roll 45, adapted to supply ink from the platen or plate 19, to the printing plate or die 20, as will be clearly apparent.

The shaft 27, isfitted with a fly-wheel 46, and a power or belt wheel 47, adapted to be driven from an engine or any other suitable source of power, for the operation of the machine.

Suitably secured to the base 48, oi the guide head 32, for the punch 30, and in vertical alignment with the opening in the die 33, for the latter is a receiver 49, for the punched or cut disks forming the bottle caps made by the punch in the working of the machine.

In the operation of the machine a strip of paper of the required thickness is placed upon the conveyor apron or belt 14, which latter is moved intermittently to bring the strip into position under the printing die 20, and over the bed 17, so as to receive an impression from the said die 20, for the printing of the strip, while the advanced strip is acted upon by th punch 32, for the cutting of a disk and in this manner bottle caps with printed matter thereon are formed in the machine in the continuous operation of the same.

The finished printed caps are deposited into the receiver 49, beneath the bed for the punch, and there removed. in any suitable manner.

The plunger 21, at the upper end 24, can be readily adjusted through the medium of the lock nuts at the said end. The ink roll 45, is augmented by the usual ink fountain 50, and spreading roll 51, while 52, is the rachet pawl actuating the ink roll to impart movement thereto, in the ordinary well known manner.

What is claimed is:

A machine of the character described, comprising a frame having a bed formed with spaced parallel side rails, rollers journaled in the side rails, an endless conveyor trained over the rollers, a printing bed beneath the upper stretch of the conveyor, a stand rising from the side rails over the printing bed and having an inking platen, a printing d-ie working through the platen, a plunger for the printing die and guided in the stand, a feed roller for th conveyor, uprights on the side rails, a cranked shaft journaled in the uprights, a disk cutting punch operatively connected to one 01 the cranks of the shaft, a punch die in the frame, to coact with the punch, a disk receiver beneath the punch die,

for the deposit of the severed disks therein, means connected with another of the cranks of the shaft to operate the feed roller, an inking roller movable over the inking platen to supply ink to the printing die, and means connected with the remaining crank of the shaft for operating the inking roller, and means operated by the connection between the shaft and punch for actuating the plunger of the printing die.

In testimony whereof I aflix my signature.

JOHN STASZAK.
