To all ywhom it may concern Be it known that I, MILTON haar Human, a citizen of the United-States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Ii'nprovenients in Trapping-Machines, of which the following is a specification.
This invention relates to improvements in wrapping or packaging machines and particularly to a machine which will wind the wrapper about the article and enable the ends te be twisted sufiiciently to retain the same in the wound condition.
The machine is particularly adapted to wrap bodies or articles having a circular shape in cross-section whereby the same may be rolled over the wrapper. As an example of such an article attention is directed to cigars, stick candy and other objects of asimilar shape. 1 i
The main object of the invent-ion is to provide a machine of simple construction which will enable the article to be Wrapped and aid the operator in effecting a twisting of the ends in a speedy and expeditious manner.
The accompanying drawings illustrate a practical embodiment vof the invention whereinm- Figure 1, illustrates the machine partly in vertical section and sideelevation. Fig. front or feed-end elevation of the same; Fig. 3, a top plan View thereof; Fig. 4, an enlarged vertical sectional detail taken on the line 451 of Fig. 3. Fig. 5, illustrates an enlarged cross-sectional detail ofone of the side guides,this section being taken on the line 5 5 of Fig. 3.@ Fig. 6, shows a side elevation of one of the roller sustaining carriages or brackets, and Fig. 7, illustrates a package such as a cigar as it is Wrapped with its ends twisted when it leaves the machine.
In `the drawing the numeral, -1, designates the ,corner posts or supports which sustain a horizontal table, 2, the latter preferably having vert-ical side and rear Walls, 3, and, 4, respectively to prevent the articles, which are usually piled or laidv thereon in readiness to be wrapped from rolling off. Atthe rear, the table has an opening, 5, through which the wrapped packages may be dropped into an inclined chute, 7, which latter is located-'beneath and at the under side of the table. v

face of the table, 2, anduhas a smooth eentral rear body portion, 8, which extends forwardly from the edge and a wider front end,'9,\ Where the `wrappmg operation begins.v i This Work bed' is of substantially a T-'shape,the head of g the Wrapperattaching end and the leg of the T serving as the rolling bed on 4which the rolling of the package takes place while the ends .of the wrapper are being twisted. work bed is best illustrated in Fig. 4, Wherein it will b e seen that the same is provided with a coneavity, 10,-which drops from substantially the front edge, 1l, and then gradually curves upwardly and at, 12, merges into the top surface of the Wider end and in front of the rear body por- By referring to Figs. 3, and 4, it will be noted that the top surface of the work bed is elevated with respect to the top surface of the table which is de.- sirable because it gives room for the opera to-rs hands during the twistingoperation, as `will presently be explained. A flexible belt or strip, 13, extends over the upper surface of the work bed and in the present instance one end, 14T, ofthis belt or strip is secured at the rear end of the leg or body, 8, adjacent to the opening, 5, and from that point of attachment Isaid belt or strip extends forwardly along and over the said top surface and then extends centrally across the Wider front end, 9, and dips or follows the contour of the concavity, 10. At the front end the belt or normally extends upwardly from the cavity and forms treme front end, 16, of said beltl or strip eX- tends beneath ablock, 17, and is rigidly secured thereto. It will th`us be noted that the belt 0r strip, 13, has no longitudinal movement bodily because its two ends are rigidly secured, and also that it has a-,fulL ness or is longer than the work bed which enables the loop, 15, to be formed therein.
On` top of the ofthe Work bed, 8,. there are provided longitudinal guide bars, 18, each of which has an overhanging top flange, 19, as clearly seen in Figs. 2, 5 and 6, ofthe drawings. These guide bars extend all the Way across the table top from the front to at least the opening, 5, at the end of the Work hed. vAt the front end the guide bars sustain a. horizontal stop bar,
a loop, 15, and the eX 20, and at the rear ends of the opening, 5,
strip table, 2, and'at each side of the guide bars the wall, 4 of the table is4 rovided with a slot, 21, iior a purpose which will presently be described.
A horizontal shaft, 22, is sustained in suitable brackebbearings, 23 at the rear of the table and said shaft servesas adrum on which one of the ends of twg.,u spacedapart belts, 2l, are wound. These belts eX# .tend from the drum through the slot, 21, and then along the inner side's of the guide bars, 18, as best shown in Figs. 3, 5 and 6 and the overhanging langes, 19, serve to prevent the belts from flopping up and down as they are reciprocated as will presently be explained. The belts extend forwardly over the table and each has its forward end attached to a bearing block, 25, which latter is provided with an upwardly extending lug, 26. One` bearing block is provided for each guide bar and each bloeit projects beneat-h the overhangingz,Y iange, 19, of the guide bar and the belts are secured to the upper surface of the blocks at one side of lug, 26, as shown in Fig. 6. Thus it lwill be understood that there are two bearing blocks, 25,-one for each belt end, 24, and both blocks 'have the same relative vertical positions between the front and ends of the ide bars and one being at one side of the work bed and the other at the opposite side of said bed, as can be seen in Figs. 2 and 3 of the drawings. A roller, 27, ex-
.tends horizontally between and has its ends supported in the Atwo spaced-apart lugs, 2G, of the bearing blocks and said roller extends through the loop,'15, of the belt or strip, 13, as best shown in'Fig. 4.
On the front vertical edge, 28, of the table, I provide two idler or guide pulleys, 29, each yof which has position et the front end of one ofthe guide bars. `Two belts, 30, each have an end secured to one of the bearin blocks and said belts then pass over the pu leys, 29 and extend downwardly and then rearwardly beneath the table, 2, where their other ends are wound on a drum shaft, 31, that extends horizontally below the table, as seen in Figs. 1 and 2.
` Fromthe foregoing explanation itwill be understood each bearing block, 25, is connected b two belts one of which, 24, extends ter to revolve.
rearwar y along the guide bar and through slot, 21, andlms its end wound on shaft, 22, and thel y other belt, 30, extends forwardly 'rom'.,the 'bearing block and then downwsrdlyrover idler, 29, and has its end wound o`n1 clrti1h shat, 31. bviously, if shaft, 22, is revolsed so es to wind belts, 2l, thereon, the bearingfblocks, 25, and roller, 27 will be drawny rearwardly,the roller traveling horizontally over theiwork-bed 8, and at this same time `the two belts, 3 0, will be unwound from drum shaft. 3l, and will cause the lat- This movement ot the bearing blocks and roller rearwardly is effected' in the present instance by means of a foot treadle, 32, which will`be depressed by the foot -o the operator, and through the conneet-ion of said treadle with the shaft, 22, by
' a band orstrap, One end of this strap 1s and pawl takes place secured to the treadle and 'the other end is Wound at, 34, on the shaft, 2,*-the winding being done in a direction reverse to the winding of the st'ra s, 2 4, on said shaft, 22, so that the unwin ing of strap, 33, from shaft,
22, will cause the winding of the straps, 24,'
on said shaft. vlkw-ill also be seen that the winding of the straps 24. on shaft, 22, will cause the unwinding of straps, 30, from the drum shaft, 31. Y
By again referring to Figs. 1 and 2 it will be seen that a tlexib e stra i, 35, is wound on the drum shaft, 31, in a irection that will cause it to wind thereon while the straps, 30, are unwinding ,therefrom and said strap, 35, depends from said drum shaft and is at tached to a foot treadle, 36. Thus it will be seen that wheel treadle, 32, is depressed the bearing'bloclts, 25, and roller, 27, will travel rearwardly over the table und treadle, 36, will be raised and when ireadlc, 36, is depressed a reverse movement of the same parts takes place.
The outer end of drum shaft, 31, is provided with a pinion, 37, which meshes with and turns a gear, 38, which latter is loosely carried on aA. short horizontal convcycr shaft, 39. A ratchet wheel ll0, is rigidly attached to said ennveyer shaft and has position at the side of the loose gear, und a pawl, 41, is pivotally mounted at the side ot the loose gear so as to engage the ratchet wheel. A spring, 42, yieldingly holds the pawl against the vface of the ratchet wheel. It will thus be seen that as the pinion, 37, is turned in one direction the gear, pawl and ratchet will rotate conveyer shaft, 39, but when a return movement of the pi ion, gear the latter will ride over the ratchet wheel. Thusl the conveyer is given an intermediate movement at each operation. of foot treadle, 32. The operation of wrapping is carried on follows A wrapper, 43, of paper tin foil or other material, or of a paper with tin foil sheet laid thereon, is laid in the concavi y, 10, at the front of the-work-bed and on op of the flexible belt or strip, 13, as sho'wn in Figs. 3 and Al,--the wrapper being of greater width than the belt or strip and lay ing cross-wise thereon with its ends projecting beyond the opposite longitudinal side edges of the belt or'strip. The article to be wrapped,' which in the present instance is shown as a cigar, 44C, is then laid on the wrapper in said concavity and the same will thus have position in front of but below the roller` 27, which passes through the loop 15, of said belt or strip. The operator then begins adepression of the foot treadle, 32, and
l simply l a5 to begin wrapping this return motioirthe stopbar, 20, which` extends horizontally between the guide bars` causes shaft 22, Vto revolve 'a direction that will wind the belts, 24, thereon thus pulling or drawing the forward ends-.of said belts and the bearing blocks, 25, attached 5 thereto rearwardly along the guide bars,4 18.` This rearward sliding of the bearing blocks carries the roller, 27, and the loop, 15, ofthe belt .or strip, 13, over the cigar and vin doing this the belt or strip farms a second loop, 45, around the cigaror other article and the edge, 46, of the Wrapper which is to first wind labout thearticle. The continued rearward movement of .the roller, 27, will cause the cigar or other article to roll up out of the concavit andonto the central body portion, 8, of 't e work bed at which point the wrapper will encircle the body of the cigar entirel but the ends will roject over the side edges of' said central ii The operator `then grasps thetwoprojecting ends of the wrapper and holds them firmly with the ngers while the cigar continues to revolve and roll along the central body, 8,-- of course the hands of the operator will folL low along with the rolling cigar while the ends ofthe wrapper' are being held by the fin ers. This revolution of the wrapper bo y, and the inclosed oiga-r, while the ends of the wrapper are being held b the operator against rotation, will obviously cause the two held ends to become twisted-both end twists, 47, (see Fig. 7 oi? the drawing) being made in the same direction, and the wrapper thus held bythe twists., The movement of the roller' is greateijthan the length -ot the work bed, 8, conseqiiently the wrapped ci ar or other article'will b'e carried to and ropped from the. end of the central 'f body portion, 8, through the opening, 5, Vand into chute, 7, which detracts the wrapper and twisted end package onto an endless conveyer, 48, which intermittently moves forward and carries the wrappedcigars. During .the travel'of the bearing blocks, 25, rearwardly to effect a wrapping of the article, the belts, 30, will be drawn from the drum shaft, 31; which effects a. revolution of said drumshaft in such! a direction that strap, 35, will be Wound therewhen the Wrapping operation is completed the said treadle, 36, is elevated and by depressing the latter the bearing blocks and roller are returned to their normal position another package. On
will form a stop for the bearing blocks to limit the forward movement of the latter.
