Description

e convened portion or the spring. There since the frame i l'oi the panel is held under the tension of the spring 25, Y tendency thereof to rattle is entirely eliminated. i

F or the purpose of concealing the slot 1% when the panel 1 is removed to provide an open body,v there is preferably employed a closure plug 2?" which comprises the spring retaining arms 28 and a bead-like head por tion 29 similar in shape to the bead or moldh1g9 on the top edge of. the'door. Fig. 7 of the drawings shows this plug in perspective above the slot 14, and it will, of course,

' be understood that when the plug is inserted in the slot the latter is entirely closed, and the head portion Q9 thereof cooperates with the head or molding 9 to'iorni a substantially unbroken surface.

ronl the foregoing, it will be apparent that one of the distinctive features of the present invention'is the provision of a yieldable connection betwen the sash panel and thedoor, which can be easily and quickly established and at the same time eliminate all possibility of rattle when the door is closed. By way of forming this yieldable connection it may be noted that when the sash is put in place on the top of the door, eachtenon element carried thereby enters one of the slotsli, which is slightly at one side of the center of the escutcheon plate 13, and moves downwardly in a substantially perpendicular plane along the vertical inner face of the spring as indicated in Fig. 4. The sash panel I may,itherefore, assume a vertical position during the greater part of its movement toward the top of the door, but upon reaching the rounded side of the convened holding hook 524, the end of the tenon becomes deflected against the face of the guard flange 23, as also indicated by dotted lines in Fig. l. This forcing of the free end of the tongue 15 by the spring 25 into engagement with the wall 23, which as previously stated is located at one side of the outer edge 14a of the slot, thus causes the entire sash to tilt inwardly on the head 9 and edge 14% of the slot l-i toward the door jainb, assuming of course that the door is open when the sash is applied thereto. .lgtcordingly it will be apparent that the sziid outer edges 14 of the slots constitute a fixed fulcrum for the l'enons 15 to tilt or cant to the sash, While the inner edges 14: of the slots lie in substantiallytlie same perpendicular plane as the inner vertical .t'ace 25*? of the s pping;

of the slot 1d withrelation tothe socket S,

and the Sitl011 of the rounded nose of the" convened holding portion Elliot the spring 25, the ejnliresash is 'givenan inward tilt away from the vertical as clearly shown in Fig" 3 of the'drawines. when thedoor is i I f closed the upper edge of the sash or frame 1 will abut with theshoulder provided by the rabbcted seat R in the top T of the automobile body, and when the upper edge of the sash panel strikes this abutment, itwill be forced outwardly against spring tension to the position shown in Fig. .2 of the drawings. All of the greatest swinging movement or play oi? the sash takes place at the upper free end thereof, while the lower edge having the groove 10 therein rocks on the beading or molding Furthermore, owing to the relatively large dimensions of the clearance slot 12 beneath the entrance slot 2 14, the rocking movement of the sash on the heading 9 is not hindered, and the spring 25 in each element 11 is relatively recto exert its full influence on the free end of the tenons 15. When the sash is seated on the door and the free end of the tonguei15 is forced into frictional contact with the inner face of the guard flange 23, the holding of the sash in position is assisted by the engagement of the rounded surface of the hooked portion 2% of the spring 25 engaging with the notch 19 of the tongue, thus preventing accidental displacement.

1 Without further description, it is thought that the many features and advantages of the present invention will be readily apparcut, and it will be understood that various changes in the form, proportion and minor details oi construction may be resorted to without departing from the spirit of the inyention or scope of the appended claims.

I claim:

1. A door construction for convertible automobile bodies comprising in combination, a door case and a door permanently hinged thereto, a removable and replaceable 1 1" sash panel adapted to have a rockable hearing engagement with the upper edge of the door and carrying tenon elements therewith, a socket delvice permanently carried by the door for each tenon and havin a loclrin and deflecting spring engaging the lower end of said tenon elements only when the sash is on the door to place the said tenons under tension and tilt the sash panel toward the door case.

economically and conveniently applied to articles of various descriptions.

In the present instance we have shown and described our invention as employed for wrapping catalogues, books, pamphlets'or the like, but this is merely for the purpose of illustrating, by a specific example, the function and mode of operation of the machine, and We wish it to be distinctly understood that the invention is not limited in its useful application to this particular pur pose, as the machine may be used for wrapping articles or objects of any character whatsoever and in connection with which its the" employment may be deemed desirable or adva ntageous.

One purpose of the present invention is the provision of a machine wherein articles may be automatically and sequentially wrapped or incased so completely as to preserve the same against such soiling and in- I jury as is liable to occur under ordinary conditions attendant upon handling, transportation and storage. X I

Another object 'is to provide a machine wherein wrapper blanks or sheets may be successively and continuously fed into position to receive the articles which in turn are sequentially and continuously presented to the blanks or sheets, certain instrumentalities acting upon the sheets and articles to accomplish the wrapping operation and then to convey the completely wrapped packages to asuitable'point of discharge Furthermore, we propose to provide amachine capable offincasing or inclosing an article in an envelop or bag-like container or wrapper, which is formed from a single' fiat blank or sheet during the wrapping operation;

A further object "of the invention is the provision of a machine wherein during the wrapping operation certain over-lapped portions or sections of the wrapper are sealed or united through the medium of an adhesive, such as paste or the like, one end of the envelop or wrapper being preferably, though not necessarily, left unsealed, and being tucked in beneath an adjacent portion of the envelop or wrapper to form a free fiapwhich may be withdrawn or opened to permit the ready removal of the inclosed article without the necessity of tearing or destroying such envelop-wrapper.

With the above recited objects and others of a similar nature in view our invention consists in the construction, combination and arrangement of parts set forth in and falling within the scope of the appended claims.

--Before entering into a detailed description of our invention we will brlefly state that it embodies, among other features, a

- table or support upon which may be placed a stack or-pile of the flat sheets or blanks from which the wrappers for the catalogues are to be formed one of the wrappers or blanks being shown in Fig. 27. Suitable sheet selecting and feeding'mechanis'm take these sheets successively and carry or present the same to sheet gripping devices mounted upon and traveling with endless carriers, in

the present instance in the nature of chains traveling over suitably arranged sprockets, the chains running beneath the bed of the machine. When a flat sheet or blank coming from the sheetf selecting and feeding mechanism is'g'rasped by one of these grippers it adjacent longitudinal edge opposite side portion of the lank, as is in-' is carried in the travel of the latter to an adhesive or glue applying device WlllCh applies glue along one si e portion of the sheet and the latter is then carried to a position directly beneath the catalogue-feeding mechanism. In the present instance this catalogue-feeding mechanism includes a magazine or hopper in which a stack or pile of the catalogues are placed in an approximately upright position or are up-ended. The catalogues are fed one at a time from this stack 0r pile and permitted to drop onto a bracket-like support, each catalogue so dropped still maintaining its approximately upright position. When the sheet is brought beneath such catalogue, the latter is tilted or swung forward and downward and permitted to drop fiat, or to a horizontal position upon the subjacent sheet, as diagrammatically indicated in Fig. 28.- The contin-- ued movement of the endless carrier now conveys the sheet with the catalogue lying flat thereon away from beneath the catalogue feeding device and one end of the blank is folded over one end ofthe catalogue to form a. loose, free flap, as indicated in Fig. 29.

The wrapper with the catalogue thereon is now brought by the carrier into position to have'one of the side sections of the blank folded over against the uppermost face of. the catalogue. The other or adhesively coated side portion ofthe blank is now folded inward so as to overlie the opposite side portion of the blank, both of these inwardly folded side portions overlying the previously folded end portion ofthe blank, and the adhesive at the edge of the overlying side portion causes the latter to adhere to the ortion of the dicated in Fig. 30; the initially tucked-in end flap remaining free, that is to say, is

preferably not pasted or attached to the adjacent side sections of the blank by the adhesive. This leaves but one end portion of the wrapper to be folded and fixed in position, and the continued travel of the carrier brings this end portion or end flap into position to receive a strip or. coating of adhesive age so that it appears as shown in Fig. 33,

the package thus completely wrapped and sealed being discharged from the machine.

In connection with our machine,we proveyer D. Thiscarrier or conveyer D in the, present lns'tance embodies two pairs. of endtraveling carriers.

messes vide automatically operating means for automatically throwing the machine under- It is of course to be understood that the various power transmitting connections and operating devices are so proportioned and timed in their relative movements that the various operations vwill take place in the order described.

Referringnow to the accompanying drawings in detail, the letter A indicates the frame of the machine which includes a suitable longitudinally slotted bed B. At

. the front end 1, of the frame is located a sheet-feeding mechanism which is indicated as an entirety by the letter C, and is best shown in Figs. 1, 3 andll. It is to be understood that this sheet-feeding mechanism may be of any suitable type or character for feeding sheets individually and successively to the traveling carrier of the ma chine, and which earner is indicated as an entirety by the letter 1).

In the present instance we have shown a form, illustrating and describing only such parts thereof as may be necessary to understand its coiiperation with the remainder of the present machine. In the type of sheetfeedlng mechanism illustrated herein, the stack or pile of sheets, indicated at S, is mounted upon a reciprocating table 2 carried by the swinging frame 3, this frame being swung by means of the worm and sector gear 4. As will be understood by reference to Fig. 11, as the table reciprocates across the top of a suction pickerroll 5, the bottom sheet of the pile or stack is withdrawn by this picker 'roll. As will be understood by reference to Fig. 3, the picker roll is intermittently subjected to suction throu h the agency of a suitable suction pump suitably connected in driving relation with the power transmission devices of the machine, a suction pipe conventionally illustrated at p leading from this pump to the picker roll. As this arrangement of sheet-selecting suction device is also'well known, it need not be further described here in detail.

Referring again to Fig. 11, as each bottom sheet is selected or picked ofi from the bottom of the pile or stack by the picker roll it is carried down between feed rollers 6 and 7 and the guides 8 and 9 to a sheet gripper device E of the carrier or conlesschains 10-10 and 1111 traveling over two pairs of sprockets adjacent opposite ends of the frame, the four endlesschains and as all of the sheet grippers travelin longitudinally of and beneath the slotted ed of the machine: endless chains, for instance, that made up of the two outside chains 10-10 carries a series or set of sheet grippers E, while the other or inside pair of endless chains 11- 11 carries a series or set of other gripping devlces such as are shown at'F, and which for the sake of convenience and distinction, much iglliip and push the catalogues, books or the may be termed pusher grippers inas- As shown in Figs. 5 and 6, at the rear end 1 of the machine is a sprocket shaft 12 which is driven through the train of gears 13, 14 and 15, the latter being on the power shaft 16. On said shaft 12 are mounted the two sprockets 17 and 17' which form the outside sprockets over which travel the chains 10-10, and th'esetwo sprockets 17- 17 have adjustably connected therewith the inner pair of sprockets 18' and 18 over which travel the inner pair' of chains 11. The adjustment of the sprockets 18 and 18 relativeto the sprockets 17 and 17 is accomplished through the racks 19 and inions 20, and it will be noted that each 0 the sprockets 17 and 17 is slotted as at 21 for the reception of the adjusting screws 22 of the companion sprockets 18.-18. Inasmuch as the sheet grippers E are carried by the outside pair of chains and the catalogue pusher grippers F are carried by the inside pair of chains, the adjustment of the sprockets just described enables the distance be tween a sheet gripper and a catalogue pusher to be made greater or smaller. We might here mention that a sheet gripper E and av pusher gripper F constitute a pair of gripping devices for conveying the wrap per and a catalogue through the machine, and of course these grippers E and F are arranged in alternate relation for this pur pose. As shown in Fig. 12, at the opposite or frontend 1 of themachine the outside pair of chains 10 travel over the sprocket members 23 whilethe inside pair of chains.

shaft 26 in turn drives other mechanisms of the machine, as will be hereinafter described.

We will now describe the specific coir struction of one of. the sheet 'ppers E, are similar a description of one will suflice.

Referring .especially to Figs. 23 and 26, itwill be seen that each gripper comprises a carriage 27 provided with the four rollers 28, one pair at each side of the carriage;

One pair of as their purpose and function is to sheet of paper, these studs being. a apted to pro ect through the openings 32 in the spaced hoolrs 33 of the gripper. These hooks 33 which are adapted to clamp the forward edge portion of the paper a ainst the plate 30 are fast with the rock sha t 34 mounted in the bearings 35 which form a part of the carriage body, as shown in Fig. 6. At the center of this shaft 34 is fastened one end of an arm 7 36, the opposite or free end of WlllGh carries the cam roller 37. The gripper hooks 33 are normally held closed or in contact with the plate 30 by means of the expansion spring 38, but when the roller 37 rides upon the cam track 39 as-shown in Fig. 11, the.

gripper hooks will be opened against the action of the spring 38 to move-the glrip er hooks into one posltion and permit t e orward edge of the sheet to engage the front stops or rods 31. Immediately, however, the cam roller 37 of the gripper E rides or passes down the curved end 40 of the cam bar 39,,the gripper hooks will be automatically thrown into closed position by the spring 38. The sheet S being thus grasped by the gripper E, as shown inFigs. 13 and 14 is carried forward to the glue applying device to have one longitudinal side ed e portion coated with a stripe of glue. s the catalogue pusher'grippers have not up to this time been brought into active operation we will reserve a specific description of the same until deseribmg the part which such pusher ggippers play in the wrappin operation. he glue-applying device, w ich is indicated as an entirety by the letter G, and b means of which the glue is to be applied to one side edge or flap of the sheet, as

shown in Fig. 27 at w, is preferably constructed as follows: Referring to Figs. 13 and 14, this glue-applying device G comprises the glue tank 42 inwhich works the glue-wallower roller'43 which contacts with the glue-applying roller 44, the upper ortions of the peripheries of these ro lers' meeting above the glue tank, and these rollers 43 and 44 are geared together by means of the gears 45 and 46. The glue. tank 42 is carried by a. frame 47, the sleeve 48 of which slides on the rod 49, while a second sleeve 50 of this bracket is threaded and receives the adjusting screw 51 having the operatinghandle 52 at one end thereof. By operatlri the handle 52 in the required direction t e glue tank together with the glue rollers and their accompanyin parts may be adjusted laterally of the pa of travel raeaeoe of the envelop to the requisite distance for properly applying a stnpe'of glue to an edge portion of the sheet, the degree of adjustment depending, of course, upon the widthof such sheet. The amount of glue on the wallower roll may be regulated and rendered uniform by means of a scraper blade 53 swin 'ngly mounted on the stud 54 and adjustab e to and from the wallower roller by the set screw 55. As will be seen from Fig. 14, the glue-applying roller 44 does not touch or contact with the portion of the bed B therebeneath, but is slightly spaced apart therefrom, and in order that the traveling sheet may receive its proper stripe of glue a small angular guide plate 56 is provided which is bolted to the adjacent portion of the bracket 47, as at 57, and the bottom of this guide is slightly inclined to the horizontal so that the sheet in its pas-- sage will be moved upward in position to contact with the periphery ofthe glue-applying roller and receive the glue therefrom. After the sheet has received its stripe of glue from the glue-applying mechanism it continues its forward travel and is brought beneath the catalogue-feeding mechanism which is adapted to supply the catalo es successively, one for each wrapper s eet brought into position therebeneath; this catalogue-feeding mechanism being indicated as an entirety by the letter H. Referring to Figs. 4 7, 8, 9,15 and 16, it will be seen that it comprises an inclined table 58 having spaced slots 59 through which partially project the pairs of rollers 60 and over these rollers run the endless feed tapes or belts 61. The catalogues shown at H are stacked on end on this inclined table as shown in Fig. 4, suitable confining side boards 62 being mounted on the right and left handv fed down to this position by the. endless tapes before referred to. -The catalogue which is in position to be fed to the wrapper mechanism rests against'this plate 64 and in contact with the preferabl rubber faced rollers 65 and 66, the perip cries of which project through slots 67 and 67 in this place and thus slig tly beyond the front face 0 the plate so the foremost catalogue will rest 'in contact with these rollers 65 and 66,

which are geared together in driving engagement to the endless chain 68, until the lowermost roller 66 is rotated by means of the intermittent gear 69, and its clutch connection shown in Fig. 10. This gear 69 in turn is driven through a mutilated gear 70 mounted on the shaft 71, as shown in Fig. 9,

aaeasee and this shaft 71 in turn is driven through the bevel gears '72and 72, the latter being mounted on the shaft 73, the bevel gear 74: of whichreceives motion throu h its corre-, sponding bevel gear 75 on the s aft 76, this shaft having at 1ts opposite end a bevel gear 77 which meshes with the similar bevel gear 78 on the vertical shaft 79, the latter being driven through the bevel gears.80 and .81, which in turn receive motion through the shaft 82 connected in driving engagement with the sprocket shaft 26 through the bevel gears 83 and 84, the sprocket shaft 26 being driven as heretofore described. Thus the lower feed roller 66 will receive'an intermittent motion and in turn will. impart a corresponding motion to its companion roller 65. This will cause the contacting catalogue to be fed downward until its lower portion.

contacts with the roller 85 mounted parallel with and beneath the roller66. The magazine will pass between this roller 85 and the correspondin roller 86 carried by the framework 0 the table 58, as shown in Fig. 4:, and, referring to this figure, 1t w1ll be understood that the table 58, the frame of .which carries this roller 86, is bodily adjustable toward and from the catalogue-sup-' porting plate 61 b means of the adjusting screw 87 threade in the screw sleeve 88 loose on the tie-rod 89, the frame of the table having slots 90 therein to permit of this. This arrangement is simply a to vary the opening or space between the forward edge of the table and the plate 6 1 and between the feed rollers to ermit the handlin of catalogues of various thicknesses. he two rollers 85 and 86 are driven through the in:

termeshing gears 91 and 92, the gear 92 being driven through the relatively large gear 93 on the stud shaft 94:, this gear 93 having integral therewith a smaller gear 95 driven" from the gear 96 on the shaft 76, and it will be further understood that this gear 96 meshes with and drives the gear 97 on the shaft 44 of the glue-applying roller 4d so that motion will be imparted through the shaft 4 1' to the gears 46 and 45 of the glue rollers thereby rotating the latter to insure the presen tation of freshly glued surfaces to the sheets. The feed tapes or belts 61 of the catalogue table 58 are intermittently driven bymeans of the intermittent bevel gears 98 and 98?,

the latter being on the shaft 99, which is geared through a pair of spiral gears 100 to the shaft 101, of one of the pair of rollers 60, and by means of this intermitttent driving of the belt'6l the catalogues will receive an intermittent feed toward the plate 6 1.- As thecatalogues are fed down between the feed rollers 85 and 86, it is to be understood that these latter rollers normally revolve. at a little greater s eed than the rollers 65' and 66. However, a er the catalogue has passed in between these rollers 85 and '86 and is engaged thereby, so as to continue to feed ownward, the roller 66 will be revolved at a greater speed than is normally imparted to it y itsusual driving or power transmission mechanism. This is accomplished by the ball and ratchet clutch drive as will be seen by reference to Fig. 10. This roller 66 is loose on its shaft 66 and between this roller end of the roller 66 thereby driving the latter'in one direction. When the rollers and 86 draw the catalogue along at a greater speed than the normal rotation of the roller 66 this roller travels at the same speed as the catalogue thereby reducing friction between the same, wh ch would occur if the roller 66 was rotati at its initial speed.

The catalogue being ed downward by the feedrollers 85 and 86 drops onto the outturned ends 103 of the flat bars 104; these bars forming a grid bracket or support for the catalogue.

Now after the sheet gripper E has taken a sheet from the sheet feeder, as shown in Fig. 3,it carries this sheet along in the travel of the conveyer and past the glue applying device as indicated in dotted lines in Fig. 13, so that the stripe of glue X is applied to one longitudinal edge of the sheet, as before stated and as indicated in Fig. 27. It

will be-noted that the sheet is carried be tween a gripper E and one of the pusher grippers F. The construction of these pusher grippers will be readily understood by reference to Figs. 24 and 25. Each pusher gripper comprises a carriage 105 surmounted by a plate 106 forming a platform. This carriage is provided with the four I wheels 107 traveling in the trackways, the carriage of course being attached to the chains 11. Mounted on the axle 112 of the carriage is a depending yoke 113, the par- .allel arms of which are formed with elongated slot's 114 through which the axle 112 passes. This yoke carries an upwardly extending hooked arm 115 which is adapted to engage the rear end of the catalogue, as hereinafter described. Loosely mounted upon the axle 112 between the arms of the yoke .is a collar 1l6 carrying an arm 117 provided at its free end with a cam roller 118. This collar 116 is also formed with a projecting lug 119 bored for-the passage of the pin 12 0, thelower end of said pin. being socketed in the bight 121 of the yoke, and a coil expansion spring 122 surrounds this pin 120 between the lug and the bight of the yoke. The normal tendency of the spring-is to hold the pushed in open position, with the cam the carriage the pusher gripper roller arm hanging vertically as shown in Fig. 24. When, however, in the travel of reaches the cam bar 123 located beneath the sheet feeding mechanism as shown in Fig. 3, it will ride up the inclined face 124 thereof, and the cam arm will be elevated so as to throw the hooked arm 115 to the position shown in dotted lines 'in Fig. 24, and thus the pusher gripper may pass freely beneath the sheet feeding devices. It continues in this position so long as the cam wheel 118 rldes on the bar 123. At this point I might mention that, as indicated in Fig. 24, this pusher gripper has three distinct positlons which it may assume, that is to say, the w de open position indicated in full lines 1n said figure, the intermediate position as indicated in dot-and-dash lines wherein the hook of the arm 115 overlies the platform 106, but 1s elevated a considerable distance therefrom, and the final catalogue gripping pos1t1on, indicated in dotted lines in said figure wherein the hook of the arm is depressed toward the platform as when gripping the catalogue.

' These positions will be referred to later on,

but at the timethe pusher gripper is riding on the cam bar 123 it is, as before stated, moved to its depressed or dotted positlon to enable it to-safely pass thepaper sheet feeding guides.

Referrin to Fi per drops 0%lover t e rounded end of the cam bar 123 it flies to its open position, at which time the sheet is being drawn through the glue-applying device and the upward and backward. movement of the hooker arm 115 will lift up the rean end of the sheet, as shown in Fig. 4. The sheet is now broughtby the carrier directly beneath the catalogue feeding device with the two grippers occupying the positions shown in Fig. 4, and the catalogue which is resting upon the bracket grid is tilted over and onto the sheet by the kicker blocks 125 fast on the shaft 76 and which have been brought into position by the turning of the shaft into position to push the catalogue off the bracket, as shownin Fig. 15. The catalogue thusfalls face downward upon the sheet and is carried along thereon. In the progress of the carrier the cam roller 118 of the pusher gripper rides up the inclined face 127 of the stepped cam Joar 128,

' and onto the level section 129.thereof, shown in Fig. 4. This causes the hooker arm 115 of the pusher gripper to assume its intermediate position shown in Fig. 17, and thus fold over the rear end lap s of the sheet on the catalogue. The continued travel of the carrier brings the forward end of the catalogue up against the rocking usher fingers 130, as shown in Fig. .16, an these pusher fingersshove the catalogue slightly rearward -on the wrapper sheet so that the rear end of the catalogue will snugly seat or fit in Fig. 18. At this "1311118, of course, both the 130 4, when the pusher grip aeaaoe this shaft is. rocked at proper intervalsthrough the link bar 132 connected at one end to the rod and at its opposite end as-at 133 to the lower end of a rocking calm lever 134 mounted on the stud 135 carried by the frame of the machine, the upper end of this lever 134 having a cam roller 136 operated by the cam 137 on the shaft 7 6. Extending parallel with the shaft 131, but somewhat in advance thereof, is a second shaft 138, which is in the nature of a right and left hand screw thread and is operated by a suitable handle 139. This shaft has threaded thereon a pair of spaced sleeves 140 carrying the guide bars 141 which terminate at their free end in the vertically inclined guide arms 142. The sleeves 140 are preferably connected through webs 143 with the sleeves 144 on the shaft 131, these latter sleeves each carrying one of the pusher fingers 130. Of-course the vertical arms 142 and the side bars 141 act' ward. and from each other to accommodate hooks or catalogues of difierent widths.

As the carrier D with the catalogue in its wrapper held as shown in Fig. 17 continues its travel, it brings these to the side folders 145, as shown in Fig. 18. These side folders which are. adjustable toward and from each other by means of the pin and slot connection 146 are of a well-known form, and together constitute a folder or former having a flaring mouth formedof the vertically inclined sides 147 gradually merging into the inturned parallel sections 148 so that the two side sections of the wrapper sheet will be folded over on the catalogue and in overlapping relation to the endflap .9. By reference to Fig. 18 it will be seen that owin to the peculiar formation of the two fol ing plates, the unglued side 8 'of the sheet will be first folded over, and subsequently the glued section 8 of the sheet will be folded over on the section 8. These two folder plates 145 are adjustable toward and from each other by means of the right and left handed screwed shaft 149 passing through the threaded sleeves 150 of the plates. Just before the catalogue with its wrapper passes into the side folder, the cam roller 118 of the pusher gripper rides up the second inclined wall 151 of the cam bar 128, and onto the top edge of this bar, as shown at the right hand side of Fig. 4, and this moves the hooked arm 115 to its final or'dotted positionshown in Fig. 24, thus firmly gripping the end of the catalogue and the end flap s overlapping the latter, in which condition the catalogue ,passes into the-side folder as indicated in menace usher gripper F sheet gripper E and the y wrapped cataowever, as the sheet gripetes the operation of drawing wrapped Catalogue through the and past the spring tension creasing blocks 152 which crease or press the side folders of the wrapper along the longitudinal-side edges of the catalogue, this sheet gripper E rides up on the cam bar 153 and is opened thereby as shown in Fig. 19, thus 153,- as will be seen by reaches the releasing its hold on the package and then continues its travel around the'sprockets, the gripper again closing by the action OfltS spring immediately 1t leaves the cam bar reference to Fig. 20. The pusher gripper F, however, pushing against the rear of the latter beneath the works the glue roller 155, this roller receiving a rotary motion through the intermeshing bevel gears 156 which may be given by any suitable power transmission gear. As the forward end section of the wrapper sheet 155 the terminals 157 of the rocking fingers 158, engage the under faceof the end portion of the sheet, and as these fingers-rock upward on their shaft159, the end of the sheet shown at s in Fig. 20 is pushed against the glue roller and receives a coating of glue therefrom. The continued advancing of the package by the pusher grippenn'ow carries it beneath the presser rollers 160 and 161, the presser roller 160 being formed by a series of annular preferably rubber disks likewise constructed, but is preferably ten-, b

the intermeshing gears mounted in spaced relation on a shaft 162, and between which disks the fingers 158 project. The lower presser roller 161 may be sioned and held up to its work by means of springs 163, yieldingly supporting the bearings of the shaft 164 of the lower roller.

The rock shaft. 159 receives its motion through the tooth segment 159' which meshes with the arcuate rack 165 at the upper end of the lever 166 mountedto swing on the pivot stud 167, the lower end of this lever being connected at 168 to the link rod 169,

the latter in turn being pivoted as at 170 to the lever arm 171 mounted to rock back and forth on the shaft 172. The presser roll 160 has a gear 160' which is driven through a gear 173 loose on the shaft 159, this gear in turn being driven by a corresponding gear 174:, which also meshes with and drives the gear 161 of the roll 161. This gear 174=is driven through the large gear wheel 175, and through this gear 175 are also driven 176 and 177 which drive the gears 178 and 179 of the rear presser rollers 178179. On the transverse rod- 180 are mounted the hangers 181 for the upper horizontal presser bars 182, which act it along withthe travel package carries the. glue pan 154 in which position beneath this glue roller 20 to 22 inclusive,

loose clutch gear member 193 -to bear against the upper surface of the catalogue and properly guide the same to the rear or lastset of presser rolls.

The presser.

device J also includes a table-like support, 7

made up of the spaced parallel bars 183 upon which the catalogue rests in its travel through the presser, the rear terminals of these bars being rounded as at 183 to cause which works in the elongated slot 191 in the frame 184, the operation of the hand shaft 187, through the train of mechanisms just mentioned enabling the table 183 with its frame to be raised and lowered to accommodate catalogues of various thicknesses as will be'readily understood.

Thus it will be seen by reference to Figs. that after the end flap s of the catalogue has had the glue applied thereto and has been folded over against the previously folded Side fiaps or sections of the sheet, as shown in Fig. 17, and the pusher gripper F has released the catalogue, by the action of the gripper passing off of the end 128 of the cam 128, the catalogue now completely wrapped will pass through the presser device J and the laps or joints firmly sealed so that the package. will appear as shown in Fig. 33, presenting a neat appearance, with the catalogue completely wrapped and'with one flap tucked in utnot secured, so that it may be readily pulled out to remove the catalogue from the that the sheet will be interposed between the gripper hook and the platform plate of the gripper the machine will be automatically stopped, thereby preventing the dropping or feeding of a catalogue when no sheet is present to receive it. This is accomplished as followsz'The power shaft of the machine is provided with the usual clutch 193 normally held in driven engagement with the by meansof the spring .19 1. The clutch shaft 195 is pivoted at 196 to the shipping lever 197 which is fulcrumed at its lower end at 198 to' a bracket forming part of the frame of the machine. This shipping lever 197 may be manuallyshifted by grasping the handle 199, to throw the clutch out. It may also be thrown out automatically to stop the mameshing with the gear 188 of the cam shaft 189, the cam 190 of chine through certain electrically controlled mechanism of the general character shown in the patent to Reifsnyder and Schwerdtle, No. 1,171,804, dated February 15,1916. In the present instance the shifting lever 197 carries an electric solenoid 200, the plunger 201 of which carries the shipper yoke 202, which engages with the grooved roller 203 sliding on the stud 204 also carried by the shifting clutch lever 197. The coil spring 205 normally tends to hold this roller 203 out of the path of the cam 206 mounted 'on the continuously rotating shaft 207. As will be seen by reference to Figs. 12 and 23, the platform plate of the gripper E is insulated from the bed of, the carriage 27. Connected to the underside of the bed of the machine but insulated therefrom, and located a short distance beyond the point where the gripper E should grasp a sheet is a contact plate 208 in circuit with the battery 209 and consequently with the solenoid 200, as diagrammatically illustrated in Fig. 26. Now should the gripper hooks fail to grasp a sheet, the contact strip 210 on the carriage will contact with the contact plate 208, and

the circuit will be closed to the solenoid, through the gripper hook, the contact strip 210, the contact plate 208, and the circuit wires, thereby energizing the solenoid, pulling inward on the plunger and bringing the sliding roller 203 in the path of the cam 206, the cam thus pushing on the roller and consequently throwing the lever 197 to disconnect the power clutch.

Should a catalogue fail to'feed, the lever will likewise be thrown out by the solenoid through the mechanism diagrammatically illustrated in Fig. 26. To the back of the supportin bars 104 which form the brackets grid for olding the catalogue just before it is deposited on the sheet we fasten and insulate a pair of contact brushes 211 between. which is located the partly insulated rotating armature 212. Now at certain times in the rotation of the armature, as

, when the insulated section thereof spans the brushes 211, no current can pass t h erethrough from the battery 209, while atother times the circuit is closed at this point. When a catalogue drops onto the supporting ends 103 of the bracket 104, it will depress the adjacent end 213 of the rocking arm 214 and lift the end 215 of the latter out of contact with the arm 211 of the brush 211, so that even if the circuit is complete or closed by the rotating armature at that point, the circuit to the ground or frame of the machine will be broken and the solenoid will not be energized. However, should the catalogue not be fed the end 215 of the arm 214 will rest upon the brush arm 211' and when the rotating armature closes the circuit between the brushes 211 the solenoid will be energized, the clutch lever .197
