MACHINE.

SPECIFICATION forming part of Letters Patent No. 693,099, dated February 1 1, 1902.

Application filed June 14,1901.

To all whom t mag/concern;

Be it known that I, ADOLPH BAYLER, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Wrapping-Machines, of which the following-is a specification.

My invention pertains to machinery for wrapping gum, chocolate, and other commodities, and has reference particularly to certain features or parts of a machine of this character set forth and described in an application tiled in the name of Thomas Adams, Sr., on the 31st day of August, 1900, and designated by Serial No. 28,678. The improvements relate particularly to the mechanism for actuating the nippers or gripping devices by which the paper strip from which the wrappers are cut is drawn forward.

In the particular work for which the machine above noted was primarily designed an inner wrapper of parafined paper and an outer wrapper bearing certain printed matter or devices are employed. The printed matter is repeated a number of times on each strip from which the outer wrappers are cut, and in order that each wrapper may bear its full legend or device and not cut into or carry a portion of that belonging to the next wrapper it s essential that the strip be advanced a definite distance each time. Owing to atmospheric changes and to thehygroscopic nature of paper it is found in practice that in some weather the strip elongates and in other weather contracts. As a consequence the wrapper-blanks cut therefrom are not always severed 0n the proper linesbetween successive designs or printed forms. In some other cases where the strip is elongated it happens that after several blanks have been cut the printed matter or design thereof will be partially clipped or cuto, while when the strip contracts there will sometimes be one entire design or form and a small portion of another on the same blank. To obviate this difficulty, I provide means for varying the throw of the lever by which the grippers are operated, so that while going always to a given point to grasp the forward end of the wrapper-blank they shall be caused to move therefrom a greater or less distance, according to the at- Serial No. 64,622. (No model.)

mospheric conditions and the consequent condition of thewrapper material.

Another serious difculty encountered in the practical operation of machines of this general class resides in the liability of the bladesor members of vthe cutting devices to play slightly or get out'of alinement, and consequently 'to produce a ragged or tearing cut. To obviate this difficulty, Iguide the two members and the actuating-lever of the cutting device in ways, and I provide a yielding pressure-plate to press and hold one blade in close contact with the other. The construction of parts whereby I attain these ends is represented in the accompanying drawings, in Which- Figures 1 and 2 are sectional elevations showing the grippers and their actuating mechanism and also the adjusting devices to which the present invention pertains; Fig. 3, a sectional View of the actuating-lever and its supporting and'adjusting devices; Fig. 4, a view of the actuating-lever and its adjusting devices looking from the opposite face from that seen in Figs. l and 2; and Figs. 5 and 6, elevations of the cutting devices and their actuating mechanism, the bed or table upon which the cutter is mounted being shown in section. Y

Referring first to Figs. l, 2, 3, and 4, A represents the bed or table of the machine; B, a trough in and through which the strip of paper or other material from which the wrapper is formed is fed. Thisjstrip is first advanced along the trough until its forward end encounters a cutting knife or blade C, which rises from beneath and passes through an opening in the bed or table B, coacting just above said bed or table with .a blade D and plate E, the latter urged and held toward the blade D by spring a, encircling a screw-stem b, which passes through a hole or opening in the blade D and screws into the plate E, the spring ct being interposed between Vthe head of the screw b and the blade D. These parts will be more fully describedlater on. When the parts C and D separate, nippers F, comprising a fixed blade c and a pivoted blade d, advance toward the delivery end of the trough B and grasp the protruding end of the paper or wrapper strip. As the construction and IOO operation of the nippers themselves constitute no part of my invention, but are set forth at length in the application of Thomas Adams, Sr., above mentioned, it is unnecessary to make further description of the same herein. is connected by a link II with a lug on the under side of the gripper or the slide which carries the gripper. This lever G is atits lower end carried by a pivot-bolt I, which passes eccentrically through a circular boss or hub e of a rocking block or yoke J. The circular hub or boss e of the yoke J is accurately fitted in a block or standard K, which constitutes a bearing for said boss and which also has a foot or base plate to give steadiness and bearing for the standard upon the base or bed of the machine. The foot or base plate of the standard K is slotted,as shown atf, Figs. 3 and 4, to receive the lower end of the lever G and preclude displacement thereof. As shown in Figs. 1, 2, and 4, the yoke J is formed with two upwardly-extending ears, which project from one face of the yoke into line or plane with the upright portion of standard K. These lugs or ears are tapped to receive thumbscrews L, which, bearing against opposite edges of the standard and being turned one forward and the other backward, serve to adjust the yoke or to swing it about the axis of the circular boss or hub e. The yoke J is slotted, as shown at g, to receive a bindingscrew or tap-bolt M, which, passing through said slot and entering a hole tapped in the standard, serves to bind the yoke to said standard and to hold it in its adjusted position. As the bolt I, which constitutes the pivot of lever G, is eccentrically located in the hub or boss e, it follows that as the yoke J is rocked the position ofthe said pivot-bolt I willfbe varied. With the yoke in its medial position-that is, with its ears equidistant from the standard K-the pivot-bolt I will under the preferred arrangement of parts occupy a position vertically beneath the center of the -boss e. Hence upon rocking the yoke J to one or the other side the axis of the bolt I, and consequently the pivotal axis of the lever G,will be thrown slightly to one or the other side of a vertical line passing through the center of the hub or boss e. This will of course vary the distance to which the lever G Will be thrown in one or the other direction.

In approaching the strip the nippers, which are at the moment open, may move a slightly greater or less distance without affecting the final result, as they will simply seize the paper a little nearer to or farther from the end of the trough or guide B; but the outward or backward movement of the nippers must be in exact proportion to the length of blank or wrapper required. By shifting the pivot or fulcrum of the lever G in the manner above described this result is accurately and certainly attained. The thumb-screws L afford means for accurately eifectin g the adjustment G indicates an upright lever, which and for temporarily holding the parts until firmly clamped by the screw or bolt M.

In practical operation this device is found to meet and answer perfectly the conditions above stated and to enable the operator readily to adjust his machine according to all variations of atmospheric conditions.

Figs. l and 2 show the yoke and the pivot for the lever in the medial adjustment. Fig. 4 shows it shifted to one side of the center of the hub or boss e, as shown by the relation of the pivot-pin to the dotted line passing vertically through the axis of said boss or hub.

Referring now to Figs. 5 and 6, illustrating the cutting mechanism of the machine, which, as before indicated, coperates with the gripper devices, the improvements thereinwill he explained. Secured to or formed upon the under side of bed or table A are vertically grooved or slotted guides h, in which moves a slide N, which carries the lower blade or cutting member C and which is reciprocated vertically by an elbow-lever O, fulcrumed in or upon a lug depending from bed or table A and furnished with a stud or bowl, which extends into a cam-groove j in a rotary cam wheel or disk P. On the upper side of the table A are standards k, having horizontally- Aprojecting ears or brackets l, both of said standards being slotted or bifurcated at their upper ends, one to receive the pivotal en d of a lever Q and the other to guide the free or moving end thereof. A pin m, passing through the upper end of one of the standards l; and through lever Q, forms a fulcrum or pivot therefor. The guiding of the free or moving end of the lever Q in the slotted post or standard la is important for the reason that it is thereby given a straight-line movement and is precluded from exerting any lateral or tipping strainupon the upper cutting blade or member D, to which it gives motion. The upper blade or member D is extended lengthwise beyond the limits of the lower blade C, and the extensions are vertically bored or perforated to t closely about vertical guiderods fn., the lower ends of which are seated in the bed or table A of the machine, while the upper ends are held in the projecting lugs or brackets Z of the standards It. This makes a firm and rigid construction and in- IIO sures the true vertical movement of the blade strip which the cutter is designed to sever.

To completelyl guard against this, there is applied to the rear face of the cutter D a pressure-plate E, which is preferably connected by a hinge o, as shown in Figs. l and 2. This pressure-plate is normally drawn to ward the cutter D by a spring a, encircling a screw-threaded stem b, which passe sthrough an opening in the cutter D and is screwed into the plate E, as shown in said iigures. The Spring d, encircling the stem l) and lying between the front face of cutter D and the head of the stern ZJ, tends constantly to draw the plate E into close contact with the blade D, and the degree of pressure may be varied, as desired,by advancing or backing the screwstem b. The inner face of the plateE is beveled slightly from the lower edge upward, as seen in Figs. l and 2, to insure proper entrance of the thin cutting edge of the lower blade C. The construction thus described insures close contact of the proximate faces of the upper and lower cutters D and Gand the consequent clean severance of the strip, the plate E yielding to permit the cutter C to rise to its proper height relatively to cutter D and between it andtheplateE. TheplateEservesthefurther purpose of a presser-foot to prevent the wrapper-strip from being carried upward past the lower edge of the cutter D. Connection is made between the lever Q and the cutter D by means of a short link T, suitably pin- `jointed to the respective members, as indicated,this connection affording sufficient play between the lever and the cutter to prevent cramping or binding of the latter, while leaving it free to follow a true vertical path. The lever Q is raised and lowered through the medium of a lever U, fulcrumed in a post or standard Vin the baseor bed of the machine and having one end connected by a rod or link WV to the lever Q, its other end being provided with a stud or bowl r, which, projecting into a cam-groove s in the wheel or disk P, is given the requisite vibration. The grooves j and s of the cam wheel or disk P are of course fashioned with due reference to each other and to the movements to be given to the respective blades or members and are such as will insure a simultaneous descent of the upper blade or member and rise of the lower blade or cutter. Preferably the lower blade will be caused to withdraw before the upper member rises from its cutting position, but this is not essential.

Vibratory motion is imparted to lever G, which actuates the nippers, by means of a cam wheel X, the periphery of which is grooved to receive a stud or bowl t, projecting from the lever, as indicated in Figs. l and 2.

Features illustrated in the drawings but not herein described are not of my invention, and hence need not be further referred to, nor have I deemed it necessary to show the entire machine, since the featureshere shown and described may be sufficiently explained and fully understood without encumbering the description with matters not original with myself.

The embodiment of the invention herein set forth is deemedtiierbest of several forms in which it may be made; but it is to be understood that the adjustable pivot I may be modied as to its mode of adjustment without departing from the general lines of my invention. So, too, the cutter may have its guides varied in form, and the plate E may be otherwise attached to the upper blade B, provided only it be held thereto by springpressure and be left free to move therefrom to the extent necessary to admit the blade C.
