(Cl; 216—12) This invention relates broadly to apparatus for automatically mounting a plurality of ele ments upon a backboard. . support the mechanism. , In certain indoor recreational games a plu ‘5 rality of printed, rectangularly shaped strips of paper are individually pasted by one end thereof in uniformly spaced, parallel rows upon a back board, usually of cardboard. chine, which latter is provided with legs 2 and carries a supporting frame work 3 designed to Said strips have Extending longitudi nally is a front drive shaft 4, suitably jour naled in appropriate bearings provided in the ‘ frame 3, said shaft being adapted to be driven by any suitable means, as the pulley wheel 5. Fixed to and actuated by the shaft 4 adjacent the unattached end folded about itself and se cured in folded relation by a transverse gummed retaining band. Printed on the inner surface one end thereof is an eccentric 8 connected to a rocker arm 8 by means of a connecting rod ‘I. of the folded portion of the strip and invisible pawl 9 adapted to successively engage the teeth to the eye by reason of the fold is information of interest pertaining to the game. Upon par ticipating in the game, a player pulls one or more of a ratchet gear Ill ?xed to an upper shaft II, Fixed to the upper end of the rocker arm 8 is a ' which latter‘is journaled in suitable bearings provided in the frame 3 and a pedestal I2, 15 of the pasted strips from the board; ruptures ‘the latter being supported by the bed plate I the paper banding seal, and unfolds the end and attached thereto by ‘bolts. Obviously, this of the strip to reveal, the previously hidden construction affords intermittent rotation of the [20 printed information which informs the player upper shaft II during continuous rotation of the 20 of matter having to do with the further progress front shaft 4. of the game. It is an object of the present invention to pro 2 vide a machine whereby said strips of papers, termed “tickets? in the trade, may be auto matically and neatly applied to the backboard in uniformly spaced parallel rows. The full nature of the invention and. other features thereof will be understood from the ac 30 companying drawings and the following descrip tion. In said drawings- ' , Figure l is a front elevation view of the ma chine; 35 ' Figure 2 is an end elevation of the same; Figure 3 is a top plan view of the same; Figure 4 is an enlarged section taken on line 4-4, of Fig. 1; . Figure 5 is a section taken on line 5--5, Fig. 3, ‘illustrating in detail the glue reservoir and I40 glue rolls; bevel gear l4 ?xed to the end of a short shaft I5 journaled in bearings attached to the frame 3. 25 Spaced sprocket wheels‘ I6 are attached to the shaft I5 intermediate its bearings and are de signed to receive a pair of spaced, parallel, end less ticket carrying chains vI'I which extend throughout the longitudinal extent of the appa ratus and encircle a second pair of sprocket wheels l8 borne by an idler shaft [9 provided on' the opposite end of the apparatus. A plu rality ofv protruding lugs I“!av are provided on each of the chains I‘! at predeterminedly spaced m U! distances and a ticket 24 is designed to be sup ported transversely across the chains I1 between each' two adjacent lugs Ila“, the ticket laying across the chains with its folded end toward the front of the machine. “ I, Figure 6 is an enlarged sectional view taken 45 Carried by the opposite end of the shaft II is a bevel gear l3 designed to mesh with a second , As best shown in Figs. 4 and 7, a guide plate ‘2|! is fastened to and supported by the frame work 3 and extends parallel to the ticket carry on line 6—6, Fig. 3; Figure '7 is an enlarged top plan view of the ticket carrying chain and guide; ‘ing chains I‘I throughout theentire extent of Figure 8 is a detail view taken on 'line a-V-a, the apparatus, the same serving as a straight Figure 9 is a perspective view of one of the edge and tending to keep the carried tickets in alignment.

Referring to said drawings, the reference nu 55 meral l designates .the bed plate of the ma and interposed between the two chains is a longitudinal spacing bar 22, this construction, as shown in Fig. 4, a?ording a separate race for the travel of each chain. A guide plate 23 disposed opposite the straight edge 29, also extends parallel to the chains‘ I'I throughout their longitudinal extent and has its upper end 5,5 2 2,121,484 occupying the same horizontal plane as that occupied by the chains I1. Consequently, the extremity of the unfolded end of the ticket borne by the chains is supported by the plate 23. Said plate 23 has a series of equally spaced upstand ing lugs 25 formed on its upper edge, the lead ing vertical edge thereof being cut away at an angle of approximately 45°. As the tickets pro the six to one transmission gearing, is effected but once to every six intermittent movements of the ticket carrying chains H, as will hereinafter be made apparent during the description of the detailed operation of the apparatus. Angle irons 15 occupy spaced, parallel ‘relation to said chains 38 for forming guide walls for the backings 53 during their forward travel. , Fixed to and actuated byrotation of the shaft 4 isv an eccentric 55 connected to a rocker arm 10 56 by a connecting rod 51, said rocker arm being folded end of each ticket will periodically en gage the inwardly directed 45° angle of each of - pivoted on the shaft 36 at the side of the ratchet the upstanding lugs 25 of the plate 23 so as to gear 48 opposite that occupied by the rocker force the folded edge of the ticket into contact arm 46. Pivoted to the upper end of the rocker arm 56 is a pawl 58 adapted to oscillate about 15 with the straight edge 26 for maintaining the the ratchet. gear 48. The majority of the teeth alignment of the traveling tickets. gressively move forward on the chain H (from 10 left to right in .Fig. 3) the extremity ofv the un Aligned with the pedestal |2 rearwardly of the latter is a somewhat similar pedestal 26. Journaled in bearings provided in the pedestals 20 l2 and 26 is a transverse shaft 21, the same at its outer end carrying a spiral gear 28 which meshes with a spiral gear 29 ?xed to the shaft ll whereby rotation of the‘ transverse shaft 21 is affected.’ Interposed between the two pedes 25 tals is a reservoir 30, designed to contain liquid glue or muc'ilage. A roller 3| mounted on a shaft 32 is designed to be partially immersed in the liquid adhesive and is rotated therein by means of a chain 33 operable on sprocket wheels car 30 ried by the shafts 21 and 32. A glue disc 34 borne by the shaft 21 contacts the roller 3| for transmitting a quantity of the adhesive to the tickets. Since the glue disc 34 occupies a posi tion in the space intermediate the chains l1 35 and the guide 23 and has its upper periphery oc cupying substantially the same plane as the car ried tickets, a suitable quantity of the adhesive on the ratchet gear 48 are covered by an at tached ‘shield 59 so that but a minor portion of the teeth are exposed to the action of the pawl 58, and, thus, the pawl 58 is effective only when contacting the exposed teeth. Here, again, it 20 may be pointed out that the operation of the rocker arm 56 and pawl 58 is six times faster than the operation of the rocker arm 46 and pawl 49. The function of the chains 38 and the 25 actuating mechanism is to successively deliver the cardboard backings 53 to and beneath the apparatus for mounting the tickets thereon, the timing of the travel of the chains and the op eration of the pawls being designed to move the board at predetermined intervals and distances so as to secure a proper aligned arrangement of the tickets on the backing, all of which will hereinafter be made apparent. Attached to the tallest vertical upright sup 35 ports of the frame work 3 and extending trans» versely of the apparatus are parallel guide rods will be deposited on the under side of the un folded end of each ticket as the apparatus is in 60 on each of which is slideable a bearing block 6|, said bearing blocks being connected by a con operation. A spreader or wiper 35 contacts the roller 3| above the level of the adhesive for as suring a uniform ?lm of adhesive on the roller 3|. necting bar , 62. Depending downwardly from each of the opposite bearing blocks 6| are two An auxiliary frame 33 extends rearwardly of the major mechanism and Supports in appropri spaced, parallel guide pins 63 on each opposite pair of which a plate 64 is vertically slideable. Provided on the outer face of each plate 64 is a roller 65 designed to be received within the 45 ate bearings a driving shaft 36 and a driven shaft longitudinally extending race 66 of an arm 61 31. Two spaced parallel, endless, backboard car rying chains 38 encircle sprocket wheels 39 ?xed pivotally attached at its front end to the frame 3. Connecting the opposite plates 64 are two to the driven shaft 31 at the rear of the machine 50 and extend forwardly to the front of the machine beneath the mounting unit (hereinafter de scribed) where they encircle sprocket wheels 40 borne by an idler shaft 4|. , A pinion 42 borne by the front shaft 4 through 55 the medium of an idler gear meshes with and drives a’ gear 43 ?xed to a rear shaft 44, the spaced, parallel guide rods 68 designed to support in sliding relation thereon a series of- mounting 50 heads 69. Protruding upwardly from each of the mounting heads 69 is a ?xed pin 10 adapted to be received and longitudinally slideable in the way of a registering guide bar 1 |. As best shown in Fig. 3, one such guide bar 1| is provided for each mounting head pin, said bars being sup ported in inwardly, convergently inclined rela to one. Fixed to and actuated by the shaft 44 7 tion by substantially U-shaped supports 12 and 13, the latter having a longitudinal extending is an eccentric 45 connected to a rocker arm 46 by a connecting rod 41, said rocker arm being slot 14 provided therein for affording adjustable ratio of the pinion to the gear herein being six pivoted on the shaft 36, which ‘latter also has ?xed thereto aratchet gear 48. Pivoted to the upper end of the rocker arm‘ 46'is a pawl 49 adapted to successively engage the teeth of the 65 ratchet gear 48 for intermittently rotating the shaft 36. Such intermittent rotation is, in turn, transmitted to the shaft 31 by an endless chain 5|)v operable on sprocket wheels 5| and 52 ?xed means whereby the spacing of the inner ends of the bars 1| may be varied when desired. Pivotally attached to the free, or inner, end of each arm 61 is the upper end of a vertical con necting rod 15, the lower end of the latter being 65 ivotally connected to a lever 16 whose opposite end ‘is pivotally attached to the frame 3. A roller 11 is appropriately attached to each lever to the ends of the shafts 36 and 31, respectively. 16 and engages and rides a cam 18 carried by Forward intermittent movement of the upper half of the chains 38 is effected through rota tion‘of the shaft 31. Said chains are designed to support a cardboard backing 53 between each the shaft 44, said roller 11 being maintained in 70 contacting relation on the cam 18 by means of a retractile coil spring 19 connecting the lever 16 with the base plate I. Obviously, the entire two sets of engaging lugs 54 borne bythe chains, mounting mechanism, including the heads 69, 76 and forward movement of the chains 38, due to are maintained elevated until the low portion 3 2,121,484‘ of the cam 18 is reached by the roller, at which time the entire mechanism drops downwardly until it strikes an underlying supporting table 80 whose upper face is a ?at plane. Continued rotation of the cam again elevates the mounting mechanism. ‘ Connecting the upper side of each bearing block Si is a rod 92 to which is pivotally con nected two rearwardly extending connecting rods 10 8!, each having its rear end pivotally fastened to a lever 82 whose lower end is pivoted to the base I. A roller 83 is appropriately carried by each lever 82 and contacts the periphery of a cam 86 mounted on the shaft 44, the roller 83 15 being maintained in contacting relation on the cam 84 by means of a retractile coil spring 85 connecting the lever 82 with the front portion of the frame 3. Actuation of the lever imparts a forward and backward reciprocable movement‘ to the bearing blocks 6! and the thereby sup 69 are thus moved apart a distance correspond ing to the spaced tickets. At this point the cam 9i actuates the vacuum control valve 90 so that the valve is opened, resulting in a suction at the mounting head ports 89. The suction applied above'each ticket results in each ticket being drawn upwardly to attach itself to the head 69 with which it is aligned. Following such attach ment of the ticket to the head, the levers 82 are . automatically moved rearwardly by the cam 84 10 and the entire mounting mechanism is thus like; wise moved rearwardly to a point in vertical‘ alignment with the table 89. As the heads 69 are moved rearwardly, the latter are moved closer together by their pins 10 and the guide II bars ‘I! so that the spacing corresponds to the desired spacing of the rows of tickets on the backboard, it being understood that the distance between the tickets is greater as they are carried on the chains than when they are attached in 20 ported mounting mechanism. rows to the board. A vacuum tank 86 is suitably supported on the rear of the frame and has a conductor line 81 - When the mounting heads with their attached tickets directly overlie the table 8|], the cam 18 - leading to an auxiliary tank 81 mounted adja is so designed and is so timed in its rotation that the‘ roller Ti of the lever 16 rides into the 26 low portion of the cam thereby forcibly dropping cent the top of the machine. A ?exible hose line 88 leads to each mounting head 69 and connects with suction ports 89 provided in the lower face of each head 69. A valve 90 is ‘inter posed between the vacuum tank 86 and the con 30 ductor line 81 and is periodically opened and closed by a cam 9! mounted on the end of the shaft 44. ‘ ‘As previously stated herein, and as illustrated in Fig. 10 of the drawings, it is the object of the invention to neatly attach the tickets in uni formly spaced parallel rows on the backboard 53. ‘The board illustrated is designed to have ‘ the mounting unit downwardly. One of . the backboards 53 has previously beendeposited on said table 85) in an appropriate position and is so supported by the chains 38, angle irons ‘I5 30 and table Bil. The lowering of the mounting unit, as above described, results in the thereby carried tickets contacting the backboard. When this stage is reached, the cam 9| in its continued rotation actuates the vacuum control valve 90 so that it is closed and the vacuum discontinued. attached thereto one hundred and twenty ‘tick With discontinuance of the suction force through‘ the head ports 89, the tickets no longer are at ets, the tickets being uniformly disposed in six rows, each row consisting of twenty tickets. It tached to the heads 69 but, rather, become ad; hered to thebackboard by reason-of the adhesive 40 will be understood, however, that apparatus may be constructed according to the instant inven tion whereby any number of tickets may be borne by the surface of the ticket next to said‘ board. ‘ mounted in any number of rows or combinations. After transfer of the row of tickets to the board, the cam 18 and its associated mechanism It may also be here pointed out that a prede termined sized space adjacent the top of the backboard is devoid of attached tickets, this space being left blank so as to accommodate printed thereafter the cam 84 and its associated mecha nism moves the unit forwardly to secure six matter, as directions, advertising, and the like. The operation of mounting the tickets is ac~ complished in the following manner: The tickets 2% are fed to the ticket carrying chains ii in any appropriate manner and one ticket is deposited, either mechanically or manu ally, on ‘the chains i7 between two adjacent sets elevates the mounting unit and immediately more tickets. ‘~ As the mounting unit moves forwardly to pick ‘ up a second set of tickets, the eccentric 45 50 through its associated rocker arm 5.6; connecting rod 41, and pawl 49 actuates the ratchet gear 48 to rotate forward slightly (one tooth), there by causing slight rotation of the connected shafts 36 and 31. Such slight rotation moves the up of lugs Ila, the folded end of the ticket being per portion of the backboard carrying chains 38 toward the front of the machine. The tickets are then carried longitudinallyof the apparatus forwardly a short distance equal to the distance toward the mounting apparatus by rapid inter— 60 mittent travel of the chains and as they suc cessively pass the glue disc 34 an appropriate desired to separate the transverse rows of tickets on the boards. Thus, the board borne by the chains beneath the mounting unit is advanced 60 forwardly the desired distance to position it quantity of adhesive is deposited on the under for deposition of a second row of tickets thereon ‘side of the ticket adjacent its non-folded end, the lugs 25 of the guide plate 23 keeping the tickets in alignment against the straight edge by the mounting unit. 2i) during travel of the tickets. When six tickets have been successively ad— vanced beneath the mounting apparatus, the levers 82 are actuated to move forwardly, thereby also moving the mounting apparatus toward the front of the machine so that it directly over lies the chains and tickets carried thereby. As the mounting apparatus is so moved forwardly, the guide pins ‘iii travel forwardly in the ways of their respective guide bars ‘H and the heads 45 > i The mounting operation continues until the required twenty rows of tickets‘ have been de 65 posited on the backboard. At this point, the space at the :topzof the backboard where no tickets are desired is beneath the unit and it becomes necessary to remove the ?lled board and replace it with another. This operation is ac 470 complished in the following manner: During the period in which the tickets are being applied to the board, the pawl 58 has been ineffectually actuated because it has been shield ed from the teeth of the ratchet gear 48 by the‘ 4 3512, 1,484 the pawl 49 to space the transverse rows of board so as to appropriately position the latter for the reception of successive rows of articles, and other means for periodically actuating the applied tickets, the exposed teeth of the ratchet gear 48 will be presented to the action of the pawl 58 and are thereby engaged. Since the pawl 58 is actuated six times faster than the vance the thereby carried backboard when said board has had the required rows of articles de posited thereon for discharging the completed pawl 49, the ratchet gear is rapidly and inter board from the apparatus and for depositing a guard. 59. However, when said ratchet gear 48 has been-intermittently rotated twenty times by backboard conveyor means to more rapidly ad mittently rotated so as to rapidly move the chains successive board within the operating area of the 38 forwardly for discharging the ?lled board from the machine and into a suitable receptacle mounting unit. (not shown). The exposed teeth on the ratchet gear‘ 48 correspond to the distance required for the chains to travel to discharge the ?lled board and position another beneath the mounting unit. dividual articles to spaced longitudinal sisting of a conveyor single ?le relation, As soon as this distance is traversed, the shield transporting a plurality of backboards in single ?le relation, a mounting unit at the junction of said conveyors, actuating means for periodically 59 presents itself to the pawl 58 and renders the latter ineffective until the last mentioned board is ?lled and is to be discharged from the appa ratus. The operation of the machine is continuous and the sameis designed to operate at compara -tively high speeds without undue strain or injury‘to any oi the mechanism. The various shafts, cams and eccentrics are produced and assembled with precision so that all movements are synchronized to avoid any interruption of operation or improper function ing of the machine. 7 ' While the invention is designed and is herein described as being utilized for pasting paper tickets on a backing, it will be understood that it is capable of other uses.
