Specification of Letters Patent.`

Patented Oct. 16, 1906.

Application flied December z. 1904. serial No. 235,268.

`To a/L whom it may concern:

Be it known that I, EDWIN FIDELL, residing in Jersey City, Hudson county, and State of New Jersey, have invented certainnew anduseful Improvements in Wrapping-Machines, of which the following is a specification.

This invention relates to means for wrappingpaclages of material, and while set forth herein as being intended for applying thewrappers to comparatively small rectangular packets of loose tobacco embodies principles and features applicable to Wrapping machines designed for other purposes.

Among the important objects of the invenv j tion are the positive and efficient operation ofthe wrapping-jaws and the association of said jaws with coacting devices for the rapid conduct of the wrapping operation. t

, j' `The proper feed of the packets in relation to the jaws is a further consideration, while the `removal and delivery of the wrapped packets in a simple and uniform manner constitute another object tobe attained.

A conspicuous vfeature of the invention in- `volves-a pair of complementary Wrappinggard to the wrapper that the jaws movable with respect to eachother and conjointly adapted for serving with an unfolded wrapper, together with coacting grippers andmechanism, whereby when a packet isfproperly positioned the grippers will be actuated to c aspthe packet at the ends and bring said packet into such relation with reacket will be infolded. on' three of its su aces by said wrapper and the latter present `extended folds, one of which is caused to overlie the other on a fourth surface of the packetand be soretainedy by subsequent successive movements yof the jaws.

While any suitable construction of means may be employed for supplying the packets to the end 4that the wrapping `operations can takeplace,.the arrangement disclosed for this purpose comprises a platform having extended pivotal side strips which vare `vibrative to.

packets are effected by so conditioning the apparatus that after the wrapping operation each pair of grippers will so move its particular packet that clasping members will seize the same and upon the relaxation of the grippers carry the packet out of position with respect to the jaws and grippers.

Where occasion requires, mechanism can b'e employed admitting of. the. convenient feeding of sheets of revenue-stamps, the latter being of extended narrow character and successively joined together along parallel transverse rows of perforations. The construction and operation of `this stamp-feeding mechanism `result in each stamp being accurately detached from its sheet .and maintained so that it can be picked up by a stampcarrying head. This stamp feeding and de- ,taching mechanism constitutes thesubjectmatter of a separate application ofmine filed June 16, 1905, Serial No. 265,488, and is dis.-

closed herein for the purpose 0f indicating its relation and function with regard to the wrapping-machine generally. 4

Thestamp-carrying head is conditioned to successively convey the stamp to a device for yapplying paste to the stamp-back and then `to a position above a wrapped packet,after which the head is operated to apply the pasted stamp to the packet, a stripper being combined with the head to insure the timely disv engagement ,of the stamp from said head.

Where the packet and stamp are such'that portions of the stamp extend beyond the packet, a supplemental device serves to properly press the stamp extensions in ,con-

packet. As will hereinafter be manifest, the novel stamp feeding andapplyingmechanism can be utilized in situations other than those set forth in the present case. are other highly advantageous featuresconnected with vthe invention, which, besides those alluded to, are clearly explained in .the subsequent detailed description.

Fig. 4L is another view of the same general character,

illustrating the provision for removing and delivering the wrapped and stamped packets,

and also other parts of the machine incontiguous relation to said provision. Fig. 5 is a detail vertical section of a part of the machine, the plane of section being radial and considerably to the left of the packet-removing provision.

Fig. 19 is a somewhat similar view of the supplemental stampafiixing device and indicating the manner in which said device operates to perform its function. Fig. 2() is an enlarged cross-sectional view of the device for applying paste to the stamp-back. showing the mechanism for affixing the stamp to the packet.

Similar reference characters are employed to designate corresponding parts in the different figures of the drawings, wherein they occur.

The main column or standardA of the supporting-frame of the machine is preferably presented by a single casting and is of the configuration generally indicated in Figs. 1, 5, and 6, from which it will appear that said standard is hollow throughout its length and embodies a lower portion A, which downwardly enlarges andk merges in a circular base-plate A2, resting on and, if necessary, bolted to the floor. prises a vertically-extended body A3, which by reason of its relatively smaller diameter with respect to the portion A contributes to This standard also'com-1f Fig. 21 1s a side view form at its junction with. the top of said por- ICO maintained in position by a sleeve A4, which is bolted to the bearing and snugly embraces the upper'part of the standard.

The upper projecting portion of the shaft B has firmly securedthereto a bevel fear-wheel b, the hub of which rests upon |the lbearing a3, and thus serves to suspend the shaft revolubly' within thestandard. Previous to lowering the shaft into position a gear-wheel b is introduced through a hand-hole a4 in the lower portion A and so held that the shaft in descending to engage within the bearing (1.2 will pass through the opening in the wheel b', and the latter can then be properly fastened to said shaft.

gear-wheel b", which meshes with a bevel `gear-pinion .Z110 on and revolving with thef drive-shaft B. Y The sleeve B3 supports and is adaptedto rotate a bowl-shaped carrier B5,

conditioned as generally indicated in Figs. l

and 5` and externally provided with broad horizontal iianges b Z112, annularly disposed, the flange b being intermediately located@- while the flange 612 is at the upper edge of the carrier. v v f j Bolted on the flange Z212 are the inner end portions c of radially-extending flat horizontal arms C, arranged in a circular series, the

saidiinner portions being of such segmental shape that they will fit edge to edge on the liange, and thereby collectively conform to the circular character ofthe latter and pro,`

vide for the radial disposition of the arms.

On each portion c is the base of a bracket C', comprising short inner and outer vertical risers c c2, each of which has at its upper end a transverse tubular bearing c3 c, revoluble .in

each of which is a pin cx cY, having secured on one projecting end of each a gear-pinion c5 c6. The hub c7 of a sector-shaped'member C2 is revolubly confined on a horizontal stud lat-` erally projecting at one side of a lower depending ear e8 of the bracket.

The downwardly-curved forward end of the bar has a transverse horizontal head C4, in which bear a series of small vertical pins c, portions of which project at the under side of the bar and are provided at their lower ends with tapering contractions cl2, merging in spherical extremities c, as illustrated more clearly `in Figs. 8, 12, 13, and 18. r Centrally at the upper sidel of the head C4 is an integral tubular boss c2", the interior of which intersects acontracted opening in the4 lower portion of the head. Vertically guided within said opening and extending up through and above the boss is the stem 021 of a stripper C5, perforated for the vertical play therein of the headed portions of the pins 017. per portion of the stem terminates in an enlargement to form an abutment 022 within the top part of the boss and between which and the bottom of the boss interior is interposed a spiral thrust-spring c2, normally tending to maintain the stripper elevated against the head, so that the lower ends of the pins will project below the under surface of the stripper. At an intermediate point of the arm C is a small vertical bearing c25, in which is rigidly mounted the lower end of a bent stop c2, the upper forward portion of which is laterally disposed. The extremity of said arm is recessed to form a socket for the inner end of a forwardly extending upwardly turned The uphook C22, also designed to serve as a stop, the 2 j and terminates in a shouldered stem, to

which is clamped by a nut d the tubular eye Z2 of a short rearwardly-extending horizontal offset at the upper end of a depending socket D of vertically-extended character, as indicated in Figs. 5, 8, Q, and l0, the passage d3 in which is entirely therethrough, a considerable portion of an intermediate part of the socket being swelled to provide for a somewhat similar enlargement of the passage, and thus while tending to reduce interior frictional surfaces yet provide extended bearing capacity within the socket.

Pivotally confined on front and rear prolizo jections d4 d5, laterally at one side of the socket, near the upper end thereof, are bearings d (Z7, in which are secured the lower portions ofvertically-adjustable rods d8 d, the upper ends of which are bolted in bosses at the corresponding ends of a pair of complementary folding jaws D2 D3. Each of these latter consists of flat bottom di, transverse wall d, and `a wall 12 at each end, the transverse and end walls'ofeach jaw being in upt3-u wardly-iiaringrelation, as indicated in the' several figures in which these features most clearly appear. The inner free edges of the end walls of both jaws have .a certain amount .of shear to present an upwardly-increasing clearance between said jaws. Secured on the arm C is a packet-holder C, consisting `of la flat bottom 028 and front and rear vert-ical walls c29 030, which normally occupy a ,position slightly inside of the vertical plane of the inner ledges of the jaw-bottoms, the under surfaces of which are in `such horizontal plane that they are adapted to be moved in .contact, or very nearly so, with the upper edges ofthe holder-walls. It will be observed that ysaid upper edgesare upwardly beveled in the .direction of the exterior surfaces 4of the walls.

The bottom of the holder C6 centrally contains `a small circular perforation registering with the vertical opening-an enlargement cal-at the under side of the bar C. This perforation and the .opening form a bearing fora short cylindrical'pin c3?, capable of moving vertically therein. This pin is capable of being maintained with a portion thereof projectinga'bove the bottom 028, through the medium of afriction-clamp C7, comprising two thin flat members C33 c, pivotally connected together at `one end, the inner straight edges of said members containing semicircularrecesses of such size that the mem-bers can yclamp the pin 032 without completely closing. The free .ends 034 of the members are relatively diverging and are connected together by a small contractile spring C35, which normally tends to cause the members to frictionally retain the pin clamped between them, but which will permit said pin to move vertically when a modera-te pressure is exerted thereon. The holder-bottomc2s is cut away, as indicated at c3, Figs. 9, 10, and 14, to snugly accommodate the pin-.clamping portions of the clamp C7, when said portions are slightly separated by the interposed pin c, said cutaway feature ;also permitting those portions v.of the clamp within the holder to present an upper surface substantially flush with the top surface of the bottom .028. The clamp in the v absence of .the pin can be readily inserted in or withdrawn from position through a transverse slot therefor in the front wall c29 of the holder, lsaid slot being in a horizontal plane common to the recess formed by the cutaway part of the bottom. When i-n position frictionally engaging the pin, the clamp, not only serves to maintain the pin in position to the desired extent,.but the pin in turn prevents the withdrawal of the clamp from the holder. Fig. 14 indicates these functions of the clamp and pin and also indicates the lower slot in the wall c2. On the lower portions of the rods d8 d, closely below the bearings d 17, are front and rear .upwardly-curved 4bearers c37 038, in the upper tubular bearings of which are bolted the ends of horizontal jourj nals 4on which are revolubly .Confined front and rear rollers 039 c4, which, together with their bearers, are .of sufficient weight .to normally contribute in throwing the foldingjaws D2 D3 away from each other, which opposite movements are limited by the jaws coming in contact with the strips 027 c2, as most clearly illustrated in Fig. 8.

Pivotally mounted on the lower flange b of the carrier B5, and disposed in the same vertical radial plane as the particular arm -C that has thus far been specially described, is a lever E, comprising a comparatively .short rear parte, downwardly curved and extending through an aperture 613 thereforin said carrier and provided at its inner extremity within the carrier with a bearing e in which is secured a short ourn-al, on `which is revolubly confined a roller e2. The longer forward part e3 of the lever E presents at its forward end a bifurcation e, the forwardly-extending tines of which have pivotally connected .thereto the u per ends of a companion pair yof substantially parallel rigid straps e5 4e5 vat .opposite sides of the 4socket D5, said straps being of the extended depending character illustratedinFigs. 1, 8, 9, and 10 and bolted at their lower ends in a plane below the lower end of said socket to a small horizontal disk e, centrally to which latter is secured the lower vextremity of an extended rod E vertically guided in the socket, the upper end of said rod having a cylindrical head e7, adapted to be stopped by and rest on the u per end of the socket when the rod is in its kowest position.

The head .elhas integrally an upwardlyextending section es, which lis rearwardly curved, as shown in Figs. 5 and 8, and which section embodies two oppositely-disposed and slightly oblique ears, in the end bearings `of which are secured short forwardly-projecting ,arbors e9 el", on which are revolubly conlined a pair of bell-crank levers E2 E3 of the sha e most clearly disclosed in Figs. 19 and 10 an which constitute the main parts of the packet-gripping means. yIt will be observed that the rpivots of said levers kare at points slightly inside of their elbows. The lower shorter members en. cl2 converge and are at vangles slightly obtuse to the other members ,of these levers, the member e11 terminating a-t about the center ofthe section es in an eye cl3, carrying a fixed pin e, which projects both at the front and rear of said eye, the front projection being the longer. The lever E3 is so supported on its Ypivot that while its vertical member is coincidently opposite the corresponding member of the lever'E2 the lower shorter member cl2 Vof said lever E3 extends in a plane immediately to the rear side of the eye e13 and terminates in a fork ,015, adapted to engage the rear projecting portion of the pin @14. At their upper extremities the vertical members of the levers are provided with tubular bearings el, in which are the horizontal Shanks @17 of the gripping-plates' which said plates are normally maintained in opposition. A coiled contractile spring E5 hasyits upper end en aged with the forked extremity ofthe lever J3, while the lower end of the spring is attached to a lower independent movable part of the machine, and thereby tends to maintain theJ levers and their gripping-plates in the position set forth in Fig. l0. On the longer forward projection of the pin @14 is revolubly confined a roller E6.

The dotted circles in Figs. 9 and 10 indicate lthe position of this roller with respect to the inner engaged ends of the levers, such roller, i

by reason of the lane of section in which these views are ta en, not appearing in full lines.

The body of the hanger D is rectangular in cross-section for the major portion of its length and is embraced by a rear horizontal loop elsmintegrally extending from the section `e8 and closely conforming to the cross-sectional shape of the body of the hanger. By thisfmeans the vertical movements of the shaft E and partsin immediate actuative relation thereto are positively guided and tendency to torsionaltwist of said shaft and contiguous parts avoided.

AI horizontal disk E is `secured on the standard A, so as to remain stationary therewith,`said disk occupying a position in the upper part of the carrier B5 and havingupper and lower annular ways f f varying at certain predetermined points to present cams. By comparing the detail perspective view, Fig. 6 with the relative position of the standard A inFig. 1 it willbe noted that both positions correspond, so that the particular location of' the upper and lowercams with regard to the rest of the machine can be generally understood. The upper way involves two recesses or depressions f 2 f 4 and an intermediate cam f 3, while the lower way, which, it will be noted, occupies a position concentrically outside of the upper way, embodies a pronounced depending cam f5, somewhat adjacent tothe depression f2, and at about one-V quarter around the cam to the right, Fig. 6, said lower waypresents another depending The weight of the roller 61 pertaining to the sectorshaped member C2, together with theweightV of the journal parts of said roller and the arm C3 and its connections, will all suffice to maintain such roller in contact with the way j and follow the depressions and cam therein. The weight of the forward portion of the lever E, together with the normal tension of the particular spring E5 coacting indirectly with wrapping-jaws D2 D3, lever E, socket E, and

all the immediate appurtenances of said element, are duplicated to any desired extent and number, and all radially disposed in a horizontal arrangement and conditioned to coperate with other parts of the machine, whereby each group will in regularand consecutive order undergo a corresponding series of operations. The character and purpose of this series of operations will clearly appear in a subse uent part o'f this description.

Rigidly secured in the base A2 of the standard A is a circular series of radially-disposed brackets G. In Fig. l, which is the Jligure best adapted for showing said brackets for clearness of illustration, but two of said brackets appear. The upper horizontal part of each bracket has an outer bearing g, in which is secured the lower end of a vertical support g', the entire circular series of said supports having their upper ends secured to the inner side of anl annular rail G to rigidly support the same. This rail and its supports partially constitute the supportingframe of the machine. Said rail is in a slightly-lower plane and somewhat outside of the position of the rollers 034 pertaining to the folding-j aws.

At a point in the machine radially corresponding with and in proximity to the means for feeding the packets to be clasped by the grippers and which means are hereinafter described in detail the rail G has bolted thereto a short vertical standard g2, the upper end of which has engaged therewith and supports a camway G2, which is of the peculiar form represented in Fig. 6 and comprises a curved rising portion g3, terminating at its top in an outward bend g4, which merges in the perforated end engaged with the standard. This cam G2 is in the path of travel of the rollers E6, coperating with the grippers, said rollers being adapted as the machine is actuated to successively ride up the portion g3 and by reason of the outward bend g4 to clear the cam and assume the position they occupied 4previous to mountin the cam. At a point considerably to the eft of the position of the packet-feed means previously alluded to a skeleton cam G3 is secured at the inner side of the rail G and is in the path of travel of the rollersc3, cooperating with the outer wrapping-jaws. Still further to the left, but

at a more interior point of the machine, is a cam-bar G4, rigidly maintained/by a bracket and rod ,support similar to one of the brackets G and its rod g, the right-hand curved 13o IOO IIO

end of saidcam, as well as its top edge, being' There is also another fixed camA G5 contiguous to the cams G3 G4.

The packet-feed means hereinbefore mentioned 'is illustrated in Figs. .1 and 2 and as disclosed involves a radially-arranged horizontal table H, which is firmly mounted at the upper ends of two vertical pillars hX, rigidly secured at `their lower ends to a basebracket similar to the brackets G; Depending from the table at the outer end thereof are hangers h, revolubly in which is a horizontal shaft h, on which and between the brackets is secured a small drum H, the upper portion of which isadapted to rotate in a horizontal plane substantially coinciding with that of the table-top, the plane of the table being somewhat higher than that of the wrapping-jaws as they move in proximity to the inner end of the table. An endless belt or carrier h2, passing around the drum, is so driven that its upper pass will receive and convey the packets to be wrapped, saidpackets being so supplied tothe belt that they will be carried by the same and delivered onto the table in a continuous series, the feed being maintained by the packets crowding those preceding. In order to insure an accurate as Well as positive feed of the packets along the table, a transverse bar H2 is supported near the inner end of and above the table to afford clearance for the packets passing beneath the bar, and .on vertical pivots h3, depending from the ends of said bar, are slightly-diverging horizontal strips 71,4, which extend outwardly above the sides of the table .and end portionv of the bellJ h2. Inner end portions of these strips are closely contiguous to the :corresponding extremity of the table H. vTorsional springs h5, coacting with the pivots and strips, tend to maintain the lat- Mounted on the projecting ends lof the shaft h to ro- ,tate therewith are cylindrical cams h6 7L, one V,at each side of the belt h2 and outer end portion of the table H. As the cams rotate, their shoulders are adapted to rvibrate the strips h, so that the latter will act to rectify any irregularity of position of the packets and -maintain them roperly during their movement on the tab e. In order to cushionthe vibratory or jogging motion thus imparted to the strips, the latter are externally provided near their outer ends with horizontally-arranged leaf-springs k7, obliquely disposed, so that their free ends will be acted upon by the cams h6 and the motion thus induced transmitted to the strips `with a modified effect. `Connected centrally to the under side of the bar H2 is the outer end of an inwardly-extending reach H3, the inner end whereof is downwardly turned to support on a level with the adjacent table end a short horizontal bar hs,

vhaving secured thereto a pair of short horizontal tongues hg, extending in the direction of and complementary to a similar pair of tongues oppositely projecting from and supported immediately from below the table end. These four tongues are adapted to receive from the table a packet and support the latter above the holders and jaws, but in the same vertical plane in which-they move, so thatthe grippers can rise and grip the packet at itsends and carry it out of position, the separated relation of the pairs of tongues permitting the upper portions of the gripperlevers to pass between the tongues. The atter will preferably be pivotally secured and provided with torsional s rings, so that while said tongues will normal y be maintained as represented in Fig. 2 they will be capable of lateral yield should they be struck by a gripper portion out of alinement, and thus avoid the possible derangement of portions at this part of the machine. a stop for properly positioning the packets to be grasped by the successive pairs of grippers. At a point considerably to the left of the acket-feed means is the stampA feeding and etaching mechanism the details of which will be described more particularly' in connection with Figs. 1, 3, 11, 12, and 13.

Rigidly bolted to the top of the sleeve A4 on the upper end of the standard A is the inner integral circular flange i of an extended arm I, which overhangs the body of the machine and terminates at its outer extremity in a short bend having a disk flange c', which occupies a` vertical plane coincident with that of the rail G, as indicated in Fig. 3. A short vertical hanger I has at its upper end a flanged .disk i2, corresponding with and bolted to the disk, and at its lower portion, but to one side, said hanger rigidly carries a radially-positioned bar I2, having a slight inclination in the direction of its outer end,.as indicated in Figs. 1, 12, and 13. It will be noticed by reference to the last Ytwo mentioned figures that the inner end of the bar I2 is configurated to provide two upper bearings and la lower intermediate bearing .arranged intriangular relation, the bearing at the extreme inner end of the bar being in a slightly-lower horizontal plane .than the companion upper bearing. Revolubly mounted in these bearings are three shafts I3 I4 I5 of comparatively smalll diameter and which are maintained in braced relation through themedium of a side bar I7, in the latter of which bear the upper shafts I3 I5 and a spindle IX, on which the lower shaft, which is of tubular character, turns.

end of the bar I6 is adapted to be detachably enga ed.` Secured on the shafts I3 I5 and spin le I at points between the bars I2 I7 are small pinions i3, Figs. 3, l1, 12, and 13, the pinion of the spindle I simply serving to communicate motion to the pinion of the shaft I5, thatv will cause the latter to revolve in a direction corresponding With that of the shaft I3. Also secured on the shaft I3 at the end thereof projecting immediately outside of the bar I7 is a small sprocket-wheel it,

which is geared by a chain belt i5 with a `sprocket-wheel i", secured on the projacting j onse-` left-hand end of the outer shaft I8. quently the said bar and the said shafts will be locked in engagement. The principal `object of the arrangements is to facilitate the application of endless bands or tapes i7 around the shafts ISIS, said bands being disposed in parallel relation. The functions of these bands will presently become apparent.

Referring to Figs. 12 and 13, firmly supported by the bars I?l I7 immediately at the inner side of the position of the shaft I3' is a cross-bar I", which is recessed. at one side to closely conform to the rounded surface of the adjacent part of the shaft I3, whereby the horizontal top edge of the bar 'will overhang and be iiush with the top of said shaft.` Secured to this bar I9 is 'a narrow transverse stamp-bed comprising a bar i, longitudinally recessed for. the reception and positive bed. The bands tu are spaced in parallel re lation, and for the purpose ofso maintaining them the shafts I4 I5 can have annular surface channels i12 for receiving and retaining said bands in guided proper position. A

`short arm 1113, adjustably clamped externally on the bar I7, extends above the same and carries a revoluble` roller il, bearing on the upper pass of the gear-chain i5 to take up slack therein. This tightener appears in Fig. 11, but is omitted from Fig. 8.

An extended tubular bearing J has a strong connection with the arm I at one side of the latteradjacent to the forward curved end portiony thereof, the bearing extending considerably above the arm and integrally presenting a short inner horizontal bracket j, provided at its extremitywith a short vertical uide which is shown as having flat paralel sides. Slidingly in thebearing J is a stem 3'7, which is of such length that end portions `thereof are adapted to project above and be-4 The stamp-bed thus i low the bearing J. A small cross-head J has a socket ja, secured in which is the upper end of the stem jz, whereby said head is su ported horizontally in position, the rear bi urcated end jt of the head slidingly embracing the guide j, which thereby permits the head to move vertically, but contributes to prevent lateral. play of the same. A strong spiral thrust-spring j, embracing the upper part of the stem jz, is interposed between the bearing J and socket js of the cross-head J and normally tends to maintain said head and the stem in an elevated position. Pivotally confined on a studprojecting at the front ofthe socket y'a is the upper end jf of a depending pitman je, the lower end of which is pivotally` attached to the outer end of an arm j7, secured on the outer end of a shaft J 7, revolubly supported in an extended radial bearing jg, bolted on the side of the arm I opposite to that at which the bearing J is situated. As indicated in Figs. 3v and 1l, the inner projecting end of the shaft J 2 has rigidly affixed thereto a crank 9, which extends horizontally toward the left and carries a spring-mounted roller jl in operative relation with a cam j on a shaft'J3 counter to the shaft J 2, said cam arrangement being designed `to positively rock the latter shaft as the oounter-shaftis revolved. It will be seen that the lifting of the crank j by the cam j will swing the arm y'7 downward, and said arm through the pitman connection depress the head J and the stem jz counter to the action of the spring j#. When the cam j turns to ermit the lower ing movement of the cran j", the spring j# will obviously operate to restore the head J and stem to their elevated position.` further effect of the spring is to `maintain the crank-roller jl in contact with the cam ju.

The shaft J 3, which is of the extended lengthillustrated most clearly i'n Fig. 3, is revolubly supported in a rear horizontal IOC bracket-bearing j, rigidly projecting from the side of the arm I, Asaid shaft being revolubly supported at its outer portion by one of a i pair forwardly-disposed horizontal bearings j j, presented by a member J4, rigidly conneoted to the outer bent part of the arm I. On the shaft J3 immediately in front of its bearing j is secured a gear-wheel J 5, adapted to be driven by a similar wheel J 6, meshing therewith and secured on the forward portion of an extended shaft J7, supported in the bearin j and also in a bearing j, the latter rigidIy on the side of the rear part of the arm I contiguous to its connection with the sleeve A4 at the top of the standard. On the inner extremity of the shaft J7 is bolted a bevel gear-wheel jl, which meshes with the wheel b on the upper part of the shaft B, and thus provides for driving the shaft J7.

An arm J8, loosely supported on the forward extremity of the shaft J7, extends transversely, as illustrated in Figs. l and 3, and
