T0 @ZZ whom it may concer-12,:

Beit known that I, SETH D. TRIPP, of Lynn, county of Essex, State of Massachusetts, have invented an Improvement in Wrapping-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the` drawings representing like parts.

. This invention relates to Wrappingmachines and is intended as an improvement upon the wrapping-machine shown and described in United States Patents No. 472,202, dated April 5, 1892, No. 5l6,136,datedv March l6, 1894, and No. 548,677, dated October 29,

1895, which is especially designed for wrapping more or less spherical objects, such as oranges. Heret-ofore it has been customary in machines of this kind to place the oran ge or other article in a wrapper and then form a twist in the gathered-in edges of the wrapper, either by holding the article and twisting the gathered-in edges or by holding the gathered-in edges and rotating the article, and such a twist given to the gathered-in edges holds the Wrapper in place.

I find in practice that by gathering inthe edges of the wrapper and then firmly jamming them together or pinching them with jaws which are constructed and arranged to more or less corrugate, score, or indent them the wrapper having its gathered-in edges so jammed or pinched together will hold onto the orange or other article sufiiciently for all practical purposes; and therefore my present invention consists in providing a Wrappingmachine with a set of jaws or nippers adapted to firmly jam together and more or less corrugate, score, orindent the gathered-in edges of the wrapper.

The invention also consists in a holder for the orange or other article which is constructed and arranged to not only hold the article with the Wrapper more or less wrapped about it while its edges are being gathered in and jammed together, but is also adapted to rise and fall so that vit may approach the holder or rest upon which the wrapper is deposited,

' and while dwelling directly beneath it may receive the article and wrapper and then descend, and, furthermore, its construction is such that as the article is forced down into its grasp with the wrapper by a suitable plunger provided for the purpose it will operate to lay the wrapper upon or about the article preparatory to having its edges gathered in and jammed together, thereby obviating the necessity of especially providing means for accomplishing this result.

Figure 1 shows in side elevation a sufficient portion of a wrapping-machine embodying this invention to enable the invention to be understood. Fig. 2 is a detail showing a side View of one of the arms of the orange-holder and its operating mechanism; Fig. 3, a detail showing the upper end of the orangeholding arms; Fig. 4, a detail of a modified form of orange-holding arm; Fig. 5, a detail of the upper end of the modified orange-holding arms; Fig. 6, a plan view of a set of jaws adapted to gather in the edges of the wrapper and jam them together and more or less corrugate or indent said gathered-in edges; Fig. 7, a cross-section of the set of jaws shown in Fig. 6, taken on the dotted line a: x; and Fig.8, a detail showing the wrapper upon the orange or other article with its edges gathered in, jammed together, and more or less corrugated or indented. j

The base A, stand or column b, rising therefrom and supporting the table or framework for the operating parts, the centering device, consisting of a ring M7 and spring-acting 1ingers u8, down through which the orange or article is forced by the plunger c', the arm c3, pivoted at c4 to the stand b, and link c2, connecting its forward end with the lower end of the plunger c', the stationarily-attached arms or brackets a d3 on the stand l), which afford bearings for the plunger c', and the wires 80, which project forward beneath the centering device and which hold the severed wrapper directly beneath said centering device, are all substantially as shown in the patents referred to, to which reference may be had.

The holder for the orange or other article which holds it and its wrapper while the edges of the wrapper are being gathered in and jammed together consists, essentially, of two arms s s', pivotally attached at s2 to a crossbar s3, secured to a vertical rod or bar s4, and said arms are bifurcated at their upper ends,

IOO

presenting like forks arranged opposite to 35, as shown in Fig. 2, is provided, which extends from tine to tine of the fork, and spiral springs s connect the tines of the opposite forks, so that a ring-like opening is produced at the upper end of the arms, which is shown as square in Fig. 3, although it may be of other shape, and is expansible.

The spiral springs s join the two arms s s' together, and adjustable limiting-stops 37 on a cross-bar S8, secured to the rod or bar s4, limit the movement of said arms toward each other. By connecting the upper end of the arms s s' in this manner it will be seen that when the orange or other article and its wrapper are forced down into the grasp of the arms they will yield and will also lay the wrapper upon or about the article the full extent of the grasp, which, by referring to Fig. l, will cover a little more than one-half the article. These arms s s' are designed to be raised and lowered in addition to yielding to receive the article and its wrapper, and to accomplish this result the rod or bar S4, to which they are pivotally connected,is movable vertically in bearings provided f or it in the stationary brackets a a3, and said arms are guided by the crossbars as, there being two such bars provided, secured at one end to the stand b and at the other end to the brackets. As a means of raising said rod or bar and arms supported by it long spiral springs s are provided, attached at their upper ends to the stationarilysupported cross-bars as and attached at their lower ends to a collar or iiange S10, adj ustably secured to the lower end of said rod or bar, said springs by their contractile force when permitted so to act lifting bodily the said rod or bar. The arms are thus raised to a point directly beneath the wrapper-holder 80, so that the wrapper held by it and the article which is forced down through the centering device will be both forced into the grasp of said arms, which are disposed t0 receive them, and said arms in their passage pass up through an opening formed by the jaws which are provided for gathering in and jamming together the edges of the wrapper, as will be described. To the lower end of the verticallymovable rod or bar 34 a loop or strap S12 is secured, which passes down and around the actuatin g bar or lever c3 for the plunger, so that said bar may be raised independently of the actuating-lever c3, but will be lowered by said actuating-lever.

After the arms s s have been raised to receive an article and its wrapper and then lowered, bodily carrying both the article and its wrapper within its grasp, it is necessary that the article shall be then held while the edges of the wrapper are gathered in and jammed together, and instead of providing special actuating devices for said rod or bar in order that it may dwell at such time while the gathering-in devices operate I have provided a locking device, shown as a latch S13, pivoted at 514 to the bracket a3 and pressed by a spring S15 into engagement with the ange or collar 310 on said rod or bar, and an arm S16 projects from said latch .313, which lies in the path of movement of the catch 317 on the actuating-lever c3, to be struck by said catch and thereby operated to move the latch and release the rod or bar. Thus when the rod or bar is depressed by the actuating-lever c3 it will be caught and held by said latch S13 until released, and it is during this time that the gathering-in devices for the wrapper opcrate; also, it is necessary before releasing said locking device and permitting the arms s s to return to separate them sufficiently for the discharge of the wrapped article, and this is accomplished by extending the lower ends of the pivoted arms s s into the path of movement of two cam-like projections S18, secured to the actuating-lever c3, so that when said actuating-lever is raised said cam-like projection 318 will strike the lower ends of said arms and by closing them together will separate the opposite ends of said arms for the discharge of the wrapped article. It will thus be seen that by the construction thus described the arms will rise and will receive in their grasp an article with its wrapper, which is more or less wrapped about it as it is re ceived in its grasp, that said arms will then descend, carrying bodily said article and its wrapper, and that they will become locked in their lowermost position, where they will dwell while the devices which gather in and jam together the edges of the wrapper perform their work, and that said arms will then be separated and the wrapped article discharged, after which the locking device will be released and the arms permitted to rise for the next article. It' desired, this holder may be employed in connection with a twisting device such'as Shown in the patents referred to, which is designed and intended to twist the gathered-in edges of the wrapper, as well as in connection with the many other devices shown in said patent.

The devices herein shown for gathering in the edges of the wrapper while the article with its wrapper is held by the holder consist of a set of jaws adapted to close together and gather in the edges of the wrapper and jam or pinch said edges tightly and by so doing will more or less corrugate or indent the wrapper, and by so gathering together the edges of the wrapper and corrugating or indenting them, as shown in Fig. 8, said wrapper will be sutliciently secured for all practical purposes. This set of jaws comprises two sets or piles of plates o t', each cut and made to present two arms, projecting at right angles with relation to eachother, and said plates c o of one set are joined together by a bolt c', passing through them at the junction of the arms, and in order that said plates maybe held more or less separated washers 122 of suitable thickness are interposed between them, and, furthermore, in order that said plates may be separated with a certain degree of freedom a spring- IOO IIO

IIS

acting washer @Sis provided for the bolt; The uppermost plate of the set of plates c v is attached tothe extremities of two bars 04, ar-

. The other set or pile of plates, which form a coperative part of the set of jaws, likewise consists of a pile of plates 05125, each cut to present two arms at right angles with relation to each other, like the platesvv, and said plates o5 v5 are arranged in a pile opposite the plates mi and so disposed with relation to said plates o i: that the arms thereof will occupy positions between said plates 'u o and move freely back and forth.

The

plates

12,5 v5 are secured together at their junction by the bolt o6, and-washers of suitable thickness are interposed between the plates f0.5 o5, in order that they may be held separated sufticientl y to receive between them the plates o U, as aforesaid, and in order that said plates fur o5 may yield somewhat bodily a spring acting washer o7 is provided. The plates o5 o5 are secured to a bar v8, having its bearings in the table and movable longitudinally in parallelism with the bars v4 o4. It is designed and intended that said plates/v n and plates v5 v5 shall move toward and from each other and thus constitute a set of jaws which gather in the edges of the wrapper and jam them firmly together or pinch them, and as they are made quite.thin and held separated the gathered-in edges of the wrapper will be more or less corrugated or indented or scored to better hold together.

As a means of moving the two sets of plates I have herein formed upon the adjoining sides or edges of the bars r4 r4 rack-teeth, and upon each side of the central bar similar rack-teeth and two pinions v9 @lo are provided, turning in suitable bearings in the table,one of which,

as o9, meshes with the rack-teeth on the bars U4 11B and the other of which, as 1110', meshes with the rack-teeth on the other bar o4 and on the opposite side of said bar t8, and said pinions are revolved in opposite ways, and the bars o4 LrL thus move Oneway, while the bar v8 will be moved in the opposite way. As a simple way of thus turning the pinions in opposite ways a double rack-bar 'U12 is provided, the rack-teeth upon one side of which engage the pinion of and the rack-teeth upon the other side of which engagethe pinion @10. The rack-bar @12 is reciprocated longitudinally to thus turn the pinions, and to thus reciprocate said rack-bar it is provided with an elongated slot @1,4 at one end, which serves as a guide-slot for the bar, the main shaft passing through said slot and said bar thereby working upon said shaft as a rest or support, and upon one side of saidvbar a projection 1215 is formed, which is engaged by a pin o1, projecting from a disk o, secured to said shaft, and upon each revolution of said disk its pin strikes said projection andv moves the rackbar one way a predetermined distance. During the revolution of said disk said pin o16 passesl by said projection @15, and when the rack-bar is thus disengaged a spring fuis, attached at one end to the rack-bar and at the other end to the frame, acts to restore or return said bar. It is obvious that this set of jaws may be moved toward and from each other in many different ways, so I do not desire to limit my invention to the particular way herein shown, although this particular way possesses some advantages owing to its simplicity of construction; nor do I' desire to limit the invention to any `particular construction of jaws so long as they operate to jam the gathered-in edges of the wrapper together and more or less corrugate or indent them.

It is obvious that a set of jaws may operate to gather in and jam together and score the wrapper regardless of how the article to be wrapped may be held, and therefore I desire it to be understood that so far as said jaws are concerned other parts of the machine may be constructed in any desirable way.

`I claiml.
